Next, mainly referring to FIG. 3, processing using the above-mentioned transfer press device will be explained.

The sheet material is fed through the pre-processing area P of the sub-press section 4, and in a specific example, in FIGS. 1 and 3, the sheet material is fed in a direction perpendicular to the page from the front side to the rear side of the page. In the pre-processing area P, the first slide 50
(FIG. 2) causes the upper forming tool 16 to act on the sheet material, and the upper forming tool 16 and the lower forming tool 14
A preform of the desired shape (for example, circular) is formed from the sheet material by the cooperative action of the two. This preformed body is attached to a button plate 72 which is reciprocated in the left and right direction in FIG.
is fed to the idle region by the action of The idle regions exist between the pre-processing region P and the transfer processing regions TI to Tlff1, and in the specific example, four idle regions are provided. This idol area! .

In I4 to I4, the preformed body is not processed, an idle area! , ~! 4 is for guiding the preformed body punched in the pre-processing area P to the transfer processing area T+, and when the distance between the pre-processing sI@P and the transfer processing area T is long, the number is If the above-mentioned distance is short or short, the number becomes small.In the transfer processing area T, - to Tl!, each upper molding is the tool 24 acts on the corresponding preform;
Through the cooperative action of the upper forming tool 16 and the lower forming tool 22, the preformed body is subjected to the required drawing process (or drawing and ironing process). In the specific example, the transfer processing area T
The diameter of the upper forming tool 24 corresponding to , (the transfer processing area existing at the upstream end as seen in the moving direction of the preformed body) is the largest, and the diameter of the upper forming tool 24 corresponding to The diameter of the forming tool 24 becomes somewhat smaller, and the transfer machining area TI! The diameter of the upper forming tool 24 corresponding to (the transfer processing area existing at the downstream end when viewed in the transfer direction of the preformed body) is the smallest.

Then, corresponding to this, the transfer processing area T

The diameter of the hole formed in the lower forming tool 22 corresponding to the hole is the smallest. As described above, the pre-formed body punched into a circular shape, for example, in the pre-processing area P is slender (to be processed Finally, for example, a cylindrical case with an open top surface is formed.

Note that the above-described transfer of the preformed body is accomplished by the action of a transfer mechanism that will be described later. In the specific example, there are 12 transfer processing regions, but when the amount of processing of the preformed body is small, the number may be reduced, and when the amount of processing of the preformed body is large, the number may be increased.

Since the second slide 54 of the transfer press section 6 is separately movable in the vertical direction, the processing pressure in the pre-processing area P of the sub-press section 4 substantially acts on the second slide 54 of the transfer press section 6. In this way, highly accurate molding becomes possible. To be more specific, in the above-mentioned type of transfer press equipment that performs punching in the pre-processing area and then performs drawing or drawing and ironing in the subsequent transfer processing area, a relatively large processing pressure is generally applied during the punching process. 2 of the processing pressure of the entire transfer press equipment.
0-30% is used. Therefore, the sub-press part is assembled into the transfer press part (i.e., the crankshaft is not supported between the sub-press part and the transfer press part, or the upper forming tool of the sub-press part is attached to the slide of the transfer press part. (also installed)
Due to the above-mentioned factors, during punching, the force in the pre-processing area comes to act on the slide of the transfer press section, and this slide tends to tilt, thus reducing the processing accuracy of the transfer press section. decreases. On the other hand, in the transfer press apparatus of the above-described specific example, the processing pressure in the pre-processing area P does not substantially act on the second slide 54 of the transfer press section 6, and the above-mentioned disadvantages are eliminated and the accuracy is improved. High-quality processing becomes possible.

Processing by the sub-press section 4 having the above-described configuration is performed as follows.

FIG. 7 shows the relationship between the rotation angle of the crankshaft 26 rotated by the main drive source of the press body 2 and the effects of various components, and the solid line A shows the relationship between the rotation angle of the crankshaft 26 and the transfer shaft 1. The solid line B shows the relationship between the vertical position of the second slide 54 of the brace part 6, and the solid line B shows the relationship between the rotation angle of the crankshaft 26 and the vertical position of the first slide 50 of the sub-press part 4. In the specific example, as understood from FIG. 8, the first slide 50 of the sub-press section 4 and the second slide 5 of the transfer press section 6
4, there is a phase shift of substantially 105 degrees, and the first slide 5G reaches the top dead center and bottom dead center substantially 105 degrees later than the second slide S4.

Next, the operation of the sub-press section 4 will be explained with reference to FIG. 7 as follows.

When the crankshaft 26 rotates in a predetermined direction and its rotational angular position reaches 0 degrees, the first movable upper part 12 and therefore the first slide 50 move as shown in FIG. 6-A, as understood from FIG. The position is approximately halfway between the position shown in FIG. 5, that is, the top dead center position, and the position shown in FIG. 5, that is, the bottom dead center position. At this time, the second slide 54 of the transfer press section 6 is brought to the top dead center position, which will be described later.

Next, when the crankshaft 26 rotates to a rotation angle position of 105 degrees, the state shown in FIG. 6-A is reached.

That is, the first movable upper part 12 and therefore the first slide 50
is positioned at the top dead center position (the state at the top dead center position will be described in detail later).

Next, when the crankshaft 26 rotates to a rotation angle position of 180 degrees, the first slide 50 is moving from the above-mentioned top dead center position toward the bottom dead center position described later, but the transfer press section 6 The second slide 54 is brought to the bottom dead center position, which will be described later.

Next, when the crankshaft 26 further rotates to a rotation angle position of 255 degrees, the state shown in FIG. 6-B is reached. (Then, the lower surface of the upper forming tool 16 provided on the first movable upper portion 12 comes into contact with the upper surface of the sheet material S existing in the pre-processing area P through the through hole 153 formed in the stripper 152, and the crankshaft 26 The subsequent rotation of the upper forming tool 16 causes the upper forming tool 16 to act on the sheet material S. As can be seen by comparing Figures 6-A and 6-B, the first movable upper part 12 When descending from the top dead center position to a predetermined position, the lower press rod 118 of the press mechanism 114 (more specifically, the lower end surface of the lower press rod 118 protruding downward from the lower surface of the upper forming tool 16) moves into the pre-processing area P. abutting the existing sheet material S, the first

6 and is forced to move relatively upward against the force of 6. When the state shown in FIG. 6-B is reached (the state in which the rank shaft 26 is rotated to a rotation angle position of 255 degrees), the lower end of the lower pressing rod 118 is inserted into the through hole of the upper forming tool 16. The lower end surface of the upper forming tool 16 and the lower end surface of the lower pressing rod 118 define substantially the same plane and act on the upper surface of the sheet material S.

Next, when the crankshaft 26 rotates a little further from the rotation angle position of 255 degrees, the state shown in FIG. 6-C is reached. mosquito(
Then, the upper forming tool 16 provided on the first movable upper portion 12 and the lower forming tool 1 provided on the first stationary lower portion 10
4 acts on the sheet material S existing in the pre-processing area P,
By the cooperative action of the upper forming tool 16 and the lower forming tool 14, a preformed body R in the form of a disc, for example, is formed from the sheet material S (thus, the sheet material S is punched out).

) When the preformed body R is formed as described above, the upper forming tool 16, which is lowered by the rotation of the crankshaft 26, and the lower pressing rod 118, which is receiving the elastic biasing force of the coil spring 136, Acts on the upper surface of body R,
The thus punched preformed body R is caused to fall downward by the action of the upper forming tool 16 and the lower pressing rod 118.

As shown in FIG. 4, the through hole 142 formed in the upper forming tool 14 tapers downward at its lower part, and the through hole 147 formed in the member 144 tapers downward.
The diameter of the through hole 142 is substantially the same as the diameter at the lower end of the through hole 142, and therefore the punched preform R can be easily dropped downward. This pre-formed body R is dropped onto the bottom surface of a recess 156 formed in the guide member 154, as shown in FIG.

Thereafter, when the crankshaft 26 rotates to a rotation angle position of 285 degrees, the state shown in FIG. 5 is reached.

That is, the first movable upper part 12 and therefore the first slide 50
is placed at the bottom dead center position.

It is drivingly connected to a sprocket portion 278 of a double sprocket 276 mounted on the rotating shaft 194 via a transmission means 274 such as a chain. Further, the sprocket portion 280 of the double sprocket 276 is drivingly connected to, for example, the main drive source of the press body 2 via a transmission means such as a chain. As described above, when the crankshaft 26 of the transfer press device described above is rotated, the rotating shaft 194 is thereby rotated in synchronization with the rotation of the crankshaft 26, and the sheet material feeding device 170 is rotated. The sheet material is fed as required as follows. In the specific example, the rotating shaft 194 is configured to rotate once when the crankshaft 26 rotates twice. Further, the sheet material feeding means 172 is composed of a known device capable of advancing the sheet material by a predetermined amount, and includes a feeding mechanism for feeding the sheet material and a feeding mechanism for holding the sheet material, although not shown. The feeding mechanism includes a pair of movable clamping members that can be selectively brought into an active state of clamping the sheet material and a non-operational state of releasing the sheet material, and the pair of movable clamping members clamp the sheet material. The holding mechanism includes a pair of stationary clamping members that are reciprocally movable in the forward direction, and the holding mechanism includes a pair of stationary clamping members that can be selectively brought into an operative state for clamping the sheet material and a non-operative state for releasing the sheet material. A pre-processing area P that exists on the downstream side of the pair of movable holding members, that is, in the sub-press section 4 when viewed in the advancing direction of the sheet material.
It is placed on the side.

Feeding of the sheet material by the sheet material feeding device described above is performed as follows. 11 and 12 show the relationship between the rotation angle of the crankshaft 26 and the effects of various components.

The solid line iB in FIG. 11 indicates the relationship between the rotation angle of the crankshaft 26 and the vertical position of the first slide 50 of the sub-press section 4. As can be easily understood, the solid line B in FIG. The solid line B corresponds to the solid line B), and the solid line indicates the relationship between the rotation angle of the crankshaft 26 and the left-right position of the driven slider 178 (left-right direction in FIGS. 8 and 9). Corresponding to the cam diagram of the cam 176, the protrusion 204 has the required shape to move the driven slider 178 as shown by the solid line)
Therefore, in the specific example, as understood from FIG. 11, when the crankshaft 26 rotates twice (that is, the movable upper part 12 of the sub-press section 4 makes two reciprocations in the vertical direction), the cylindrical cam 176 rotates. one rotation (i.e., the support slider 17
8 makes one reciprocation in the left and right direction).

Next, the operation of the sheet material feeding device will be explained with reference to FIGS. 11 and 12 as follows. In addition, substantially two rotations of the crankshaft 26 from the rotation angle position of 285 degrees in the first rotation to the rotation angle position of 285 degrees in the third rotation will be described.

The crankshaft 26 is at the rotation angle position of 285 degrees during the first rotation (
At this time, while the movable upper part 12 of the sub-press section 4 is rotating from the bottom dead center position to the second rotation angle position of 45 degrees, a pair of stationary clamping members (not shown) of the holding mechanism
is maintained in its active state, ensuring that the sheet material is held in position without being advanced. During this time, the pair of movable clamping members (not shown) of the feeding mechanism are held inactive and are moved backwards (thus, in the forward direction of the sheet material, i.e., in the direction perpendicular to the plane of the paper in FIG. 8). (However, since the feed mechanism is inactive, this return movement does not move the sheet material.) Then, when the crankshaft 26 rotates to the second rotation angle position of 45 degrees, the return movement of the movable clamping member of the feeding mechanism is completed. At this time, in the sub-press section 4, processing of the sheet material existing in the pre-processing area P is completed, and the upper tool 16 and the lower pressing rod 118 (see FIG. 5) provided on the movable upper part 12 of the sub-press section ) rises upward from the pre-processing area P (therefore, the upper tool 16 and the lower pressing rod 118 do not act on the sheet material present in the pre-processing area P).

Next, while the crankshaft 26 rotates from the second rotation angle position of 45 degrees to the rotation angle position of 165 degrees, the stationary clamping member (not shown) of the holding mechanism is held in an inactive state and The movable gripping member of the feeder is held in an operative state, and the movable gripping member is moved forward, ie, in the direction of advancement of the sheet material. Furthermore, during this period, the support slider 178 is moved forward, that is, in the direction shown by arrow 282 (FIG. 9), by the action of the cylindrical cam 176.

When the stationary clamping member is inactive, movement of the sheet material is enabled, and when the movable clamping member is activated, the sheet material is clamped between the pair of movable clamping members, thus as the movable clamping member moves forward. The sheet material is advanced. Furthermore, when the support slider 178 is moved in the direction indicated by the arrow 282 by the action of the cylindrical cam 176, as can be seen from FIGS. through the swinging member 18
2 is rotated in the direction shown by arrow 284.

Ru. When the swinging member 182 is pivoted about the pin member 222 in the direction shown by the arrow 284, the support slider 186 is rotated in the direction shown by the arrow 284 via the second connecting arm 184.
86 and the sheet material feeding means 172
is moved to the left in FIGS. 8 and 10 together with the support slider 186. As shown above, the crankshaft 26 moves 2 degrees from the 45 degree rotation angle position of the second rotation.
As is easily understood, while the rotation angle is 165 degrees, the sheet material feeding means 172 advances the sheet material by a predetermined amount, and the feeding means reciprocating mechanism 17
4 moves the sheet material feeding means 172 by a predetermined amount in the direction shown by arrow 286, that is, to the left in FIGS. It is fed diagonally to the left with respect to the forward direction. Then, the crankshaft 26 rotates at 165 in the second rotation.
When the movable clamping member rotates to the rotational angle position of
The forward movement of the 7 crystals also ends (therefore, the sheet material feeding means 1
72 in the direction indicated by arrow 286 also ends). still,
During this period, the movable upper part 12 of the sub-press section 4 passes through the top dead center position (it reaches the top dead center position when the rotation angle of the crankshaft 26 reaches 105 degrees) and descends. Upper tool 16 and lower pressing rod 118
does not act on the sheet material existing in the pre-processing area P.

Next, while the crankshaft 26 is rotated from the 165-degree rotation angle position of the second rotation to the 45-degree rotation angle position of the third rotation, the stationary clamping member (not shown) of the holding mechanism is in the operating state. At the same time, the movable clamping member (not shown) of the feeding mechanism is held in an inactive state, and the movable clamping member is further moved back.

When the stationary clamping members are activated, the sheet material is clamped between the stationary clamping members and held securely. Furthermore, when the movable clamping member becomes inactive, the movable clamping member becomes movable relative to the sheet material clamped by the stationary clamping member, and can be moved back without substantially acting on the sheet material. Ru. During this period, as can be easily understood from FIG. 11, the movable upper part 12 of the sub-press section 4 (see FIGS. 2 and 5) is at the bottom dead center position (the rotation angle a position of the crankshaft 26 is 285 As described above, the movable upper part 12 and the stationary lower part 10 of the sub-press part 4 act on the part of the sheet material existing in the pre-processing area P of the sub-press part 4 in order to pass through the bottom dead center position. Then, in the pre-processing area P, the sheet material is processed as required (punching in the specific example).Then, the crankshaft 2
6 is rotated to the third rotation angle position of 45 degrees, the return movement of the movable clamping member is completed in the same manner as described above.

After that, while the crankshaft 26 rotates from the 45 degree rotation angle position of the third rotation to the 165 degree rotation angle position,
A stationary clamping member (not shown) of the holding mechanism is held in an inactive state and a movable clamping member of the feeding mechanism is held in an active position, and the movable clamping member is moved forward, ie, in the direction of advancement of the sheet material. be done. Furthermore, during this period, the support slider 178 is moved backward, that is, in the direction shown by arrow 288 (FIG. 9), by the action of the cylindrical cam 176. When the stationary clamping member is inactive, movement of the sheet material is enabled, and when the movable clamping member is activated, the sheet material is clamped between the pair of movable clamping members, thus as the movable clamping member moves forward. The sheet material is advanced. Furthermore, when the support slider 178 is moved in the direction indicated by the arrow 288 by the action of the cylindrical cam 176, as can be seen from FIGS. 9 and 10, the first connecting arm 180 The swinging member 182 is rotated in the direction shown by the arrow 290 via. When the swinging member 182 is pivoted about the bottle member 222 in the direction indicated by the arrow 290, the second connecting arm 1
84, the support slider 186 is moved in the direction indicated by arrow 292, and the sheet material feed means 172 is moved together with the support slider 186 to the right in FIGS. 8 and 10. As shown, the crankshaft 26
As is easily understood, while the sheet material is rotated from the 45 degree rotational angle position of the third rotation to the 165 degree rotational angle position, the sheet material feeding means 172 advances the sheet material by a predetermined amount; The means reciprocating mechanism 174 moves the sheet material feeding means 172 in the direction indicated by arrow 292, ie, in FIGS.
The sheet material is moved by a predetermined amount to the right in the figure, and thus the sheet material is fed diagonally to the right with respect to its advancing direction toward the pre-processing area P of the sub-press section 4.

Then, when the crankshaft 26 rotates to the third rotation angle position of 165 degrees, the forward movement of the movable clamping member ends,
The backward movement of the driven slider 178 by the cylindrical cam 176 also ends (therefore, the movement of the sheet material feeding means 172 in the direction indicated by the arrow 292 also ends). In addition, even during this time, the movable upper part 12 of the sub-press section 4 does not act on the sheet material existing in the pre-processing area P.

Next, while the crankshaft 26 is rotated from the 165 degree rotational angular position of the third rotation, through the 285 degree rotational angular position of the third rotation, to the 45 degree rotational angular position of the fourth rotation,
As described above, a stationary clamping member (not shown) of the holding mechanism is held in an active state and a movable clamping member (not shown) of the feeding mechanism is held in a non-activating state, and the movable clamping member (not shown) of the feeding mechanism The member is moved back. Therefore, during this time, the sheet material is reliably held by the stationary clamping member, and the sheet material is subjected to the desired processing as described above.

As described above, the above-mentioned sheet material feeding device 1
70, a sheet material feeding means 172 advances the sheet material by a predetermined amount every one revolution of the crankshaft 26, and a feeding means reciprocating mechanism 174 advances the sheet material every two revolutions of the crankshaft 26. The means 172 is made to reciprocate once (more specifically, in the first rotation, the sheet material feeding means 172 is made to move forward by a predetermined amount in a predetermined direction substantially perpendicular to the advancing direction of the sheet material, and in the second rotation, the sheet material feeding means 172 is made to reciprocate by a predetermined amount In order to move the material feeding means 172 back by a predetermined amount in a direction opposite to the above-mentioned predetermined direction, the sheet material is reliably fed through the pre-processing area P in a so-called staggered manner. As a result, the sheet material can be used effectively in the processing in the pre-processing area P of the sub-press section 4, and it becomes possible to reduce waste of the sheet material.

A knockout actuation mechanism 556 is provided for each of the three sets of knockout mechanisms 526 corresponding to T1g to T1g. The four knockout actuation mechanisms 556 have substantially the same configuration, and one of them will be described next.

The illustrated knockout actuation mechanism 556 includes an actuation cam 558
, a driven rod 56 that is moved up and down by an operating cam 558.
0, and an actuating movement member 562 that acts on the knockout mechanism 526. In the space between the support base 8 and the support base plate 548, a rotation shaft 564 extending in the lateral direction (in the left-right direction in FIGS. 1 and 19, and in the direction perpendicular to the plane of the paper in FIG. 18) is rotatably installed. An actuating cam 558 is mounted on the shaft 564. This rotating shaft 558 rotates in synchronization with the crankshaft 26 (FIG. 2), and when the crankshaft 26 rotates once, it rotates once in the direction indicated by an arrow 566. The driven rod 560 is attached to the support base plate 548 via a support member 568 so as to be slidable in the vertical direction. A U-shaped bracket portion 570 is provided at the upper end portion of the driven loft 560 (the upper end portion protruding upward from the support member 568), and this bracket portion 570 has a pin member 570.

Furthermore, support brackets 576 are attached to the bottom surface of the support base plate 548 at intervals in the lateral direction using mounting screws 577, and an actuation movement member 562 is attached between the support brackets 576 via a support shaft 578 so as to be freely swingable. has been done.

One end side (the right end side in FIG. 20) of the actuating movement member 562 has an elongated rectangular shape, and the driven rod 5 is attached to this one end.
A screw member 580 that abuts on 60 is screwed together. Further, the other end side has a substantially triangular shape that widens laterally toward the other end, and three abutment pins 582 are screwed into this other end at intervals in the lateral direction. Each of the abutment pins 582 acts on the lower rod 536 of the corresponding knockout mechanism 526. The aforementioned actuating movement member 562 is resiliently biased counterclockwise in FIG. That is, in the specific example, protrusions 584a and 584b are provided at both ends of the actuating movement member 562, and pin members 586a and 586 are provided on the protrusions 584a and 584b.

Coil springs 596a and 5 through openings formed in
96b is interposed. Therefore, the actuating movement member 562
is the second one due to the action of coil springs 596a and 596b.
0, the driven rod 560 is elastically biased counterclockwise, thereby biasing the driven rod 560 upward;
The driven roller 574 is brought into elastic contact with the circumferential surface of the actuating cam 558.

With this structure, when the actuating cam 558 rotates in the direction shown by the arrow 566 and the driven rod 560 moves downward, the lower end of the driven rod 560 acts on the threaded member 580 to cause the actuating movement. The moving member 562 is pivoted clockwise in FIG. 20 against the elastic biasing forces of coil springs 596a and 596b. (Then, the abutment pin 582 of the actuating movement member 562 comes to act on the lower end of the lower rod 536 of the corresponding knockout mechanism 526, and thus the knockout pin 528 is moved against the elastic biasing force of the spring member 540. It is moved upward via a lower rod 536, a connecting loft 534, an intermediate rod 532, and an upper rod 530, which are moved upward.

Processing by the transfer press section 6 having the above-mentioned configuration is as follows:
It is carried out as follows.

FIG. 21 shows the relationship between the rotation angle of the crankshaft 26 rotated by a main drive source (not shown) and the actions of various components. The solid line A in FIG. 21 indicates the relationship between the rotation angle of the crankshaft 26 and the vertical position of the second slide 54 of the transfer press section 6. The solid line E indicates the relationship between the rotation angle of the crankshaft 26 and the vertical position of the molded body holding member 422 of the molded body holding means 414.
(corresponding to the cam diagram of the first cam 426 in FIG. (corresponding to the cam diagram of the second cam 480 of the second actuating means 478), the solid line G indicates the rotation angle of the crankshaft 26 and the knockout actuating mechanism 556.
(Accordingly, it corresponds to the cam diagram of the operating cam 558), and the dashed line H indicates the relationship between the rotation angle of the crankshaft 26 and the knockout mechanism 5.
The relationship with the vertical position of No. 26 knockout pins 528 is shown.

Next, referring mainly to FIG. 21, the operation of the transfer press section 6 will be summarized as follows.

While the crankshaft 2& rotates from the 0 degree rotation angle position to the 180 degree rotation angle position, the transfer press section 6
The second slide 54 of is moved downward (i.e., from the top dead center position to the bottom dead center position shown in FIGS. 3 and 15), during the lowering of the second slide 54. , between the rotation angle position of 10 degrees and the rotation angle position of 110 degrees of the crankshaft 26, the molded body holding member 422 of the molded body holding means 414 and the molded body holding means 4
The molded body holding members 476 of Nos. 16, 418 and 420 are the second
It is moved downward as shown by solid line E and broken line F in FIG. That is, with reference to FIG. 15 and FIG. 17-A, in the molded body holding means 414, the driven member 427 is rotated clockwise in FIG. The swinging arm 428 is rotated in the 17th-A direction via the connecting member 430.
The movable sleeve member 4 is rotated counterclockwise in the figure.
The molded body holding member 422 attached to the molded body 72 is moved downward. Then, when the crankshaft rotates to a rotational angle position of 100 degrees, the preformed body (in a specific example,
A pre-formed body holding member 422 acts on the upper peripheral edge of the pre-formed body (this pre-formed body has only been subjected to a punching process, so it has a disc shape, for example), and the pre-formed body holding member 422
22 presses and holds the preformed body in the transfer processing area TI. 15 and 18, in the molded body holding means 416 (and 418, 420), the driven member 482 is moved clockwise in FIG. 18 by the direction indicated by the arrow 488 of the second cam 480. As a result, the movable arm 484 is rotated clockwise in FIG. 18 via the connecting member 486, and the plurality of molded body holding members 476 attached to the movable member 516 are integrally moved downward. Then, when the crankshaft rotates to a rotational angle position of 100 degrees, the transfer machining areas T3 to Ts (and T4 to T91
The pre-formed bodies transferred to Tl@ to T+*) (the pre-formed bodies transferred to these transfer processing areas have been subjected to drawing or drawing and ironing in the previous transfer processing area, so they are, for example, approximately cylindrical. The molded body holding members 476 corresponding to the upper end periphery (which is the shape) act, and each preformed body holding member 476 holds the preformed body in the corresponding transfer processing area T2 to Tl! Press and hold.

On the other hand, when the crankshaft 26 rotates to a rotation angle position of about 120 degrees, each of the upper forming tools 16 provided on the second slide 54 moves to each transfer machining area T1 to Tl! (As understood from the above description, in this case, each preform is applied to the transfer processing area T'+ to T, t as required.
), in the specific example, the transfer processing areas T1 to Tl! Because the drawing or drawing or ironing process is performed in the preform, the preform becomes elongated on the downstream side in the transport direction, and due to this, the forming process of the upper forming tool 16 The transfer processing is performed from the transfer processing area located downstream in the transfer direction. As described above, the upper forming tool 16 is transferred to the transfer processing area T.

It is understood from FIG. 20 that the forming process of the preformed body is started by the cooperative action of the lower forming tool 14 and the upper forming tool 16 in the transfer processing regions TI to T1g. As shown in FIG.
is moved downward as shown by the dashed line H in FIG. 21 against the elastic biasing force of the spring member 540 (at this time,
As will be readily appreciated, the upper rod 538, intermediate rod 532, connecting loft 534, and lower rod 536 of the knockout pin 526 are also moved downwardly).

When the crankshaft 26 rotates to a rotation angle position of 180 degrees, the state shown in FIGS. 3 and 15, that is, the second slide 54 is located at the bottom dead center position, and each transfer processing area T, TI2 In this step, the preformed body is subjected to the desired forming process by the cooperative action of the lower forming tool 14 and the upper forming tool 16.

Next, while the crankshaft 26 rotates from the 180 degree rotation angle position to the 360 degree rotation angle position, the second slide 54 of the transfer press section 6 is moved upward (i.e. from the bottom dead center position). (moved to top dead center position). While the second slide 54 is rising,
The molded body holding member 422 of the molded body holding means 414 is raised by the opening amount from the 180 degree rotational angular position of the crankshaft 26 to the 240 degree rotational angular position, and further from the 280 degree rotational angular position of the crankshaft 26. It is raised again until it reaches the rotation angle position of 325 degrees (second
1) as shown by the solid line E in FIG.

That is, referring again to FIG. 15 and FIG. 17-4, when the molded body holding member 422 is raised, the spring means (not shown) is activated as the first cam 426 rotates in the direction indicated by the arrow 434. The action causes the driven member 427 to rotate counterclockwise in FIG. 17-4, thereby causing the connecting member 43
The swinging arm 428 is rotated clockwise in FIG. 17-4 through the movement of the movable sleeve member 472, and the molded body holding member 422 mounted on the movable sleeve member 472 is moved upward. On the other hand, in the knockout mechanism 526 corresponding to the transfer machining area TI, the driven rod 560 of the knockout actuation mechanism 556 is moved by the solid line G in FIG. It is lowered as shown in . Referring to FIG. 20, the driven rod 5 is inserted through the screw member 580.
60 acts on the actuating movement member 562 and the actuating movement member 56
2 rotates clockwise in FIG. Then, when the actuation movement member 562 rotates by a predetermined amount due to the action of the action cam 558 (at the time when the crankshaft 26 has rotated to a rotational angle position of about 220 degrees), the movement member 562 provided in the actuation movement member 562 The abutment bottle 582 is connected to the knockout mechanism 52
6, and thereafter the driven rod 5
As the pin 60 is lowered, the knockout pin 528 is raised as required. As described above, in the transfer machining area T1, the molded body holding member 422 is also lifted by the rising body of the upper forming tool 16, and the knockout pin 528 is also raised as required, so that the molding is not performed in the transfer machining area T1. The processed preformed body (for example, a disc-shaped body is molded into a cylindrical body, for example) is raised by the action of the knockout pin 528.

Then, when the crankshafts 2 and 6 rotate to a rotational angle position of 275 degrees, the lifting of the knockout pin 528 is substantially completed, and the preformed body formed in the transfer processing area T is separated from the knockout pin 528 and the preformed body. It is held between holding members 422.

Such preformed body holding member 422 and knockout pin 52
The preformed body held between the preformed body holding members 4 and 8 is then held by a transfer mechanism as described later, and the preformed body holding member 4
22 (rising starting from the 280 degree rotation angle position of the crankshaft 26), the preformed body holding member 422
The holding by the knockout pin 528 is released, and the preformed body is thus delivered to the transfer mechanism.

Furthermore, while the second slide 54 is being raised,
The molded body holding member 476 of the molded body holding means 416 (and 418° 420) is raised as shown by the broken line F in FIG. It will be done. That is, the 15th
18, when the molded body holding member 476 is raised, the driven member 482 is moved in the direction shown by the arrow 488 of the second cam 480 in FIG. 1B by the action of a spring means (not shown). This causes the swinging arm 484 to rotate clockwise in FIG. 18 via the connecting member 486, and the molded body holding member 476 attached to the moving member 516 is moved upward. . On the other hand, in the knockout mechanism 526 corresponding to the transfer machining area Ti (and T, to T+g), similarly to the knockout mechanism 526 corresponding to the transfer machining area T, the rotation angle position of the crankshaft 26 is 275 degrees from the 175 degree rotation angle position. The driven rod 560 of the knockout actuating mechanism 556 is lowered as shown by the solid line G in FIG. 21 until the rotational angle position is reached.

Thus, as described above, the actuation movement member 562 is rotated, and the abutment pin 582 provided on the actuation movement member 562 is rotated.
(acts on the lower end of the lower rod 536 of the corresponding knockout mechanism 526 and acts when the crankshaft 26 is rotated to a rotation angle position of approximately 220 degrees), the knockout pin 52
8 is raised as required. As shown above, the transfer processing area Tt (and T, to T+z)
In this case, since the knockout pin 528 is also raised as required as the upper forming tool 16 is raised, the preformed body (for example, a cylindrical one) formed in the transfer processing area Tt (and T, to T+z) is (which is further shaped to be somewhat elongated) is raised as required by the action of the knockout pin 528. Then, when the crankshaft 26 rotates to a rotation angle position of 275 degrees, the lifting of the knockout pin 528 is substantially completed, and the transfer machining area T8 (and T3 to T
The preformed body formed in step 13) is held between the knockout pin 528 and the preformed body holding member 476. The preformed body held between the preformed body holding member 476 and the knockout pin 528 is then held by a transfer mechanism as described below, and the preformed body holding member 476
The above-described rise (starting from the 280 degree rotational angular position of the crankshaft 26) causes the preform holding member 476 to
The holding by the knockout pin 528 is released, and the preformed body is thus delivered to the transfer mechanism.

The preformed body delivered to the transfer transport mechanism as described above is sent to the next transfer processing area as will be described later. The above-described operation is performed every rotation of the crankshaft 26. Thus, the preformed body (for example, a disc-shaped one) fed to the transfer processing area T1 is transferred from the transfer processing areas TI to T+. While being transferred through □, each transfer processing area T, to T
At +z, processing is performed as required, and the finished product is formed into, for example, a cylindrical shape.

As understood from the above description, the transfer press section 6 as described above has the following features.

First, in the idle region, the transfer processing region T following areas 11 to 4, drawing is performed on the plate-shaped pre-formed body, so the length of the pre-formed body changes greatly before and after the forming process. It turns out. Due to this, in the past, a preformed body holding member for holding the preformed body was configured to be moved up and down by two cams. That is, one of the cams lowers the preform holding member as the second slide ``lowers'' to press and hold the preform holding member present in the transfer processing area TI, and as the second slide r rises. The other cam temporarily stops the rising of the preform holding member as the second slide V rises, and then lifts the preform holding member by a predetermined amount. It increases the

Therefore, in the conventional cam, when the action of both cams is switched (i.e., the time when the action on the preformed body holding member is transferred from one cam to the other cam), there is contact between the driven member and both cams. There is an inconvenience that a high-speed molding process cannot be achieved due to vibrations caused by the shock caused by the detachment. On the other hand, in the transfer press section 6 described above, the first actuating means 424 in the molded body holding means 414 adjusts the length of the vertical stroke of the molded body holding member 422.
(in the specific example, the first adjustment mechanism 452 for
The swing arm 428 and the connecting member 4 are adjusted by the adjustment mechanism 452.
In particular, by displacing the position of the connecting portion 30, the lowermost position of the preformed body holding member 422, that is, the 21st
(In the figure, the position of the crankshaft 26 can be adjusted from a rotation angle position of 100 degrees to a rotation angle position of 180 degrees.) and a second adjustment for adjusting the vertical position of the molded body holding member 422. mechanism 454 (in the specific example, such second adjustment mechanism 454
In particular, by changing the length of the pre-formed body holding member 422, the
(in the figure, the position of the crankshaft 26 can be adjusted from a 240 degree rotation angle position to a 280 degree rotation angle position). As a result, as shown by the solid line E in FIG. 21 (□), it is possible to move up and down as required, and high-speed molding can be achieved without generating the above-mentioned impact.

Second, it is necessary to hold the pre-formed body as required in the transfer processing area T, and also in the transfer processing areas T2 to T, t, and each transfer processing area T2
~Tl! Conventionally, each transfer processing area T2 to T1□
An actuating means including a cam was provided for each molded body holding member corresponding to the molded body.

Therefore, the configuration of the transfer press section becomes complicated, the overall size of the apparatus becomes large, and the manufacturing cost becomes high. On the other hand, in the transfer press section 6 described above, the plural molded body holding members 476 are moved by the moving member 516.
The moving member 516 is attached to the second actuating means 478.
The single second actuating means 47
8, the plurality of molded body holding members 476 are integrally held in the second
The transfer press section 6 can be moved as shown by ff1llF in FIG. 1, simplifying the configuration of the transfer press section 6 and reducing manufacturing costs. In addition, when a plurality of molded body holding members 476 are moved together, if the lengths of the preformed bodies in each transfer processing area are different, there is a possibility that the preformed bodies cannot be held reliably. However, in the specific example, each knockout mechanism 5
26 has a spring member 540 that elastically biases the knockout pin 528 upwardly, the difference in preform height is compensated for by the elastic deformation of the upper spring member 540, thus causing some of the preform height to be biased upwardly. The preformed body can be held securely regardless of the difference in length. Due to the above, in the specific example, the knockout pin 528 is further positioned at the uppermost position, that is, from the 275 degree rotational angular position of the crankshaft 26 to the approximately 480 degree rotational angular position in FIG. When in this position, this knockout pin 528 is configured to be held by the action of a spring member 540 (!p, between the lower surface of the upper rod 530 and the upper surface of the intermediate rod 532, (configured so that a gap is created to accommodate the height difference).

Thirdly, in the transfer press section 6 mentioned above,
As understood from FIG. 20, the knockout actuation mechanism 5
56 operating cams 558 and the rotating shaft 564 on which the operating cams 558 are mounted are connected to the support base 8 and the support base plate 548.

In the specific example, a pawl opening/closing cam 632 is inserted into the opening 626, and a pair of screw members 6 screwed onto the rear end of the gripping pawl 616 are inserted.
By bringing 34 into contact with the claw opening/closing cam 632,
A claw opening/closing cam 632 is mounted so as to move together with the gripping claw 616.

This pawl opening/closing cam 632 has a cam groove 636 formed in its lower part. The cam groove 636 is shown in FIGS. 23 and 24.

As shown above, 1. As can be easily understood by comparing FIG. 24 and FIG. 26, the opening/closing bar 60 is
6a (or 606b) is moved in the direction shown by the arrow 612, the roller 640 is moved in the direction shown by the arrow 612 relative to the pawl opening/closing cam 632, and the roller 640 is moved into the cam groove 636. Due to this movement, the gripping claws 616 are moved outward, ie, to the left in FIG. 24. Also, contrary to the above, the opening/closing bar 606a (or 606b) is relatively aligned with the arrow 614 with respect to the transfer bar 6σ4a (or 604b).
When the roller 640 is moved in the direction shown by the claw opening/closing cam 6
32 in the direction shown by the arrow 614, and the roller 640 is moved along the cam groove 636, the gripping claw 616 is moved inward, that is, to the right in FIG. .

Next, referring to FIGS. 22 and 23, the actuating means 608 for moving the transfer bars 604a and 604b and the opening/closing bars 606a and 606b will be described. The illustrated actuating means 608 includes a cylindrical cam member 642, It includes a first driven slider 644 and a second driven slider 646. To explain further, a pair of support rods 650a and 650b are spaced apart from each other in the direction indicated by arrows 612 and 614 in the downstream portion 648 of the transfer processing area T1□ when viewed from the direction in which the preformed body is transferred in the transfer press section 6. A first driven slider 6 is slidably attached to the supporting rods 650a and 650b.
Both ends of 44 are attached. A rectangular opening 652 is formed approximately in the center of the first driven slider 644, and a driven roller 656 is rotatably mounted on the lower surface of both end portions of the first driven slider 644 via a pin member 654. The support rods 650a and 650b to which the first driven slider 644 is mounted extend in the direction of the transfer processing region T''+z, and their ends are connected to a connecting block 658, respectively. Furthermore, one ends of the transfer bars 604a and 604b described above are connected by a mounting screw.Therefore, when the first driven slider 644 is moved as described later, the transfer bars 604a and 604b are connected to each other through the support rods 650a and 650b and the connection block 658. Transfer bars 604a and 604b are reciprocated as required.Furthermore, a pair of support rods 660a are spaced apart between both ends of the first driven slider 644.
and 660b are slidably mounted in the directions shown by arrows 612 and 614.

The second driven slider 646 is the first driven slider 6.4.
4, and both ends thereof are slidably attached between the support rods 660a and 660b. Accordingly, the second driven slider 646 is located within the opening 652 of the first driven slider 644 relative to the first driven slider 644 at the arrows 612 and 61.
It is movable over a predetermined range in the direction indicated by 4. Support rod 660a to which this second slider 646 is attached
and 660b also extend in the direction of the transfer processing area T+□, and their ends are connected to the connecting member 662, respectively. Further, one end of the aforementioned opening/closing bars 6063 and 606b is connected to both ends of the connecting member 662 by a mounting screw. Further, a pin member 664 is implanted on the lower surface of the second driven slider 646, and a driven roller 666 is rotatably mounted on the pin member 664. As shown above, the second driven slider 6
46 is moved as described below, the support rod 660a
and 660b and the opening/closing bar 6 via the connecting member 662.
06a and 606b are reciprocated as required.

A cylindrical cam member 642 is disposed below the first driven slider 644 and the second driven slider 646. The cam member 642 has a cylindrical body portion 668, and a protrusion 670 having a predetermined width and a desired shape is provided on the circumferential surface of the body portion 668.
A concave groove 672 of a desired shape is formed on the circumferential surface of 0. A first driven slider 6 is provided on both sides of the protrusion 670.
A driven roller 6.56 mounted on the groove 672 is positioned and engaged with the driven roller 6.56, and a second driven slider 646 is located within the groove 672.
A driven roller 666 mounted on is positioned and engaged therewith. Therefore, the protrusion 670 of the cam member 642
The recessed groove 672 acts as a cam action part for moving the second driven slider 644.
It acts as a cam action part for moving the 6. This cylindrical cam member 642 rotates in synchronization with the crankshaft 26 (FIG. 2), and when the crankshaft 26 rotates once,
Rotate.

Transfer of the preformed body by the transfer transfer mechanism 602 having the above-described configuration is performed as follows.

Referring again to FIG. 21, FIG. 21 also shows the relationship between the rotation angle of the crankshaft 26 and various components in the transfer mechanism 602.

That is, the solid line J in FIG. 21 shows the relationship between the rotation angle of the crankshaft 26 and the movement of the transfer bars 604a and 604b, and therefore corresponds to the cam diagram of the protrusion 670 of the cam member 642). The solid lines in (and FIG. 7) indicate the rotation angle of the crankshaft 26 and each gripping claw 616.
(Accordingly, it corresponds to the relative relationship between the cam diagram of the protrusion 670 of the cam member 642 and the cam diagram of the concave groove 672).

Next, the operation of the transfer mechanism 602 will be summarized as follows, mainly referring to FIG. 21 and FIG. 22.

While the crankshaft 26 (FIG. 2) rotates from the 310 degree rotational angular position of the previous rotation to the 70 degree rotational angular position of the next rotation, the transfer bars 6048 and 604b are moved to the preform shown by arrow 612. is moved in the direction of transport. Second

As shown in FIG. , and by the movement of the second driven slider 646, the support rods 660a and 660b and the connecting member 6
The opening/closing bars 606a and 606b are connected to the arrow 61 via 62.
It is moved in the direction shown by 2. Therefore, during this period, the transfer bars 604a and 604b and the opening/closing bar 6
Because there is no relative movement between 06a and 606b, each gripping pawl 616 continues to be held in the operative position shown in FIG.
The preformed body held between the gripping claws 616 of one transfer bar 604a and the gripping claws 616 of the other transfer bar 604b is transferred in the direction shown by arrow 612 as transfer bars 604a and 604b move. (The function of holding the preformed body by positioning the gripping claws 6'16 at the above operating position will be described later).

Then, when the crankshaft 26 rotates to the above-mentioned 70 degree rotation angle position, the transfer bars 604a and 604b
Then, the movement of the opening/closing bars 606a and 606b is completed, and each gripping claw 616 attached to the transfer bars 604a and 604b is moved to the corresponding idle area ■8 to ■4.
and transfer processing areas T1 to TI! The preform is then transferred to the next area as required. During this time, as can be seen from FIG.
44 pressing members 356 and 392 (FIG. 14), a plurality of upper forming tools 16 (
3 and 15), and molded body holding means 414, 4
16. Molded body holding members 422 and 4 of 418 and 420
76 (FIGS. 3 and 15) are located above the idle regions (1) to (4) and the transfer processing regions T (T1t), respectively, and therefore accommodate the above-mentioned transfer force of the preform.

Next, while the crankshaft 26 further rotates from the rotation angle position of 110 degrees to the rotation angle position of 160 degrees (
Note that when the crankshaft 26 rotates to a rotation angle position of 140 degrees, transfer bars 604a and 60, which will be described later,
4b), the gripping claw 616 is moved as shown by the solid line in FIG. Referring to FIGS. 23, 24, and 26, during this period, the second driven slider 646 moves along the arrow 612 relative to the first driven slider 644 due to the action of the groove 672 of the cam member 642. (Note that between the rotation angle position of 140 degrees and the rotation angle position of 160 degrees of the crankshaft 26, the first driven slider 644 is moved as described later by the action of the protrusion 670 of the cam member 642. is moved in the direction indicated by arrow 614, so that the second driven slider 646 moves in the direction indicated by arrow 614.
(in the direction indicated by arrow 412 relative to driven slider 644). Thus, the above-described movement of the second driven slider 646 causes the opening/closing bars 606a and 606b to move toward the arrow 612 relative to the transfer bars 604a and 604b as described above.
The opening/closing bars 606a and 606b are moved in the direction shown by
Due to the action of each driven roller 640 mounted on the transfer bar 604a and the cam groove 636 provided on each gripping claw 616, the gripping claw 616 is located on the outside in the opening direction, that is, in the gripping claw 616 mounted on the transfer bar 604a, as shown in FIG. and the gripping claw 6 attached to the transfer bar 604b in the upper part in FIG.
16, it is moved downward in FIGS. 22 and 23. Thus, transfer bar 604a
Then, the holding of the preformed body by the gripping claws 616 of 604b is released (such holding is released by the transfer bar 604a).
and 604b), each pre-formed body is in the idle region! , to I4 are held as required by the action of the pressing members 356 and 392 (FIG. 14) of the holding means 338, 340, 342, and 344, and the molded object holding means 414, 416 are held in the transfer processing regions T1 to Tlt. .41
8 and 420 molded body holding members 422 and 476 (third
It is held as required by the action shown in FIG. 15).

Then, when the crankshaft 26 rotates to a rotation angle position of 160 degrees, the transfer bars 6041 and 6 described above
04b and the opening/closing bars 606a and 606b, each gripping claw 616 is positioned at the retracted position shown in FIGS. 23, 24, and 25, and does not act on the preformed body.

Between the above-mentioned rotational angular position of 140 degrees and the rotational angular position of 260 degrees of the crankshaft 26, the transfer bars 604a and 604b are moved in the direction opposite to the direction of transfer of the preformed body shown by arrow 614. Referring again to FIGS. 22 and 23, during this time, the protrusion 6 of the cam member 642
70 causes the first driven slider 644 to become real*J.
It is moved as shown in (Fig. 21). Thus, the movement of the first driven slider 644 causes the transfer bars 604a and 604b to move forward in the direction indicated by the arrow 614, as described above. When the transfer bars 604a and 604b start reciprocating, as can be seen from FIG. Therefore, the preformed body is not gripped between the pair of gripping claws 616, and the gripping claws 616 do not act on the preformed body transferred as described above. Reciprocal movement of transfer bars 604a and 604b is allowed.

Then, when the Kurarev shaft 26 rotates to a rotation angle position of 260 degrees, the above-mentioned return movement of the transfer bars 6043 and 604b is completed, and the transfer bars 604a and 604b
Each gripping claw 616 attached to 4b has a corresponding idle area! 1~! 4 and transfer processing areas TI to T
It is positioned opposite to 1□. Therefore, each gripping claw 516 has adjacent areas (!, to I4 and T, to T
, e) can be moved back and forth between.

On the other hand, while the crankshaft 26 is being rotated as described above,
While being rotated from the 60 degree rotation angle position to the 230 degree rotation angle position, the arrow 61 of the first driven slider 644
Similarly to the movement in the direction indicated by 4, the concave groove 6 of the cam member 642
72 also moves the second driven slider 646 at substantially the same speed in the direction indicated by arrow 614. Therefore, during this time, transfer bars 604a and 604
There is no relative movement between the opening/closing bars 606a and 606b, and each gripping claw 616 is in the retracted position (FIG. 23 to
It continues to be held in the position shown in Figure 5).

While the crankshaft 26 rotates from the rotation angle position of 230 degrees to the rotation angle position of 280 degrees (in addition, when the crankshaft 26 rotates to the rotation angle position of 260 degrees, as described above, the transfer bars 604a and 604b When the backward movement of the gripping claw 616 is completed, the gripping claw 616 is moved as shown by the solid line in FIGS. 9 and 21. Referring again to FIGS. 23, 24, and 26, during this period, the second driven slider 646 moves in the arrow direction relative to the first driven slider 644 due to the action of the groove 672 of the cam member 642. 614

4). Thus, the above-mentioned movement of the second driven slider 646 moves the opening/closing bars 606a and 606b in the direction indicated by the arrow 614 relative to the transfer bars 604a and 604b, as described above, and the opening/closing bars 606a and Due to the action of each driven roller 640 mounted on transfer bar 606b and the cam groove 636 provided on each gripping claw 616, the gripping claw 616 is moved in the inner gripping direction, that is, in the gripping direction of the gripping claw 616 mounted on transfer bar 604a, as shown in FIG. The grip claw 616 attached to the transfer bar 604b is moved downward in FIG. 23, and upward in FIGS. 22 and 23. The gripping pawls 616 are thus positioned in the operative position shown in FIG. 26, and each preform is held between the gripping pawls 616 of transfer bars 604a and 604b. Note that when the crankshaft 26 rotates to a rotation angle position of approximately 280 degrees, the required forming process of the preformed body is completed in the transfer processing area T to TI2, and this preformed body is molded. Body holding means 414.4
16. Molded body holding members 422 and 4 of 418 and 420
76, and therefore the gripping claws 61
6 grips the pre-formed body after the required molding process. and,
When gripping the preformed body, use the transfer bar 604a.
Since the return movement of 604b and 604b has been completed, the above-mentioned gripping of the preformed body is achieved as required.

Thereafter, when the crankshaft 26 rotates to a rotation angle position of 310 degrees, the transfer bar 6 as described above is rotated again.
04a and 604b Opening/closing bars 606a and 60
6b starts to move forward, and the preformed body gripped as described above is transferred between gripping claws 616 of transfer bars 604a and 604b.

As described above, in the transfer transport mechanism 602 described above, the upper forming tool 16 of the transfer press section 6 is in the transfer processing area TI to Tl! The transfer of the preform (i.e., the forward movement of transfer bars 604a and 604b) is performed when the upper forming tool 16 is in the transfer processing area T to the TiK
The return movement of the transfer bars 604a and 604b is performed while acting on the preformed body existing in the preformed body (including immediately before and after acting on the preformed body), and the crankshaft 2
The above-mentioned transfer of the preform is carried out every 601 revolutions.

In the transfer press apparatus of the specific example, a transfer defect detection means is further provided in conjunction with the transfer transfer mechanism 602 described above. Referring again to FIG. 3, the illustrated conveyance failure detection means includes a control means (not shown) for controlling the main drive source of the press body 2 and a plurality of (in the specific example, one
5) preformed body detection means 676 are provided. Each preform detection means 676 can be constituted, for example, by a proximity switch, which is known per se, and is disposed proximately below the transport path of the preform, as described above. As shown in FIGS. 3 and 14, between the areas (2) to (4) and the transfer processing area (T), the preformed body detection means 676 is attached to the plate member 404, and the support guide plate (398) is as described above. In this way, the preformed body being transferred is detected. In addition, between the transfer processing area TI and T1□,
As shown in FIG. 5, the preform detection means 676 is mounted between adjacent holders 412 and detects a preform transferred over the lower forming tool 22 as described above.

Signals from each preform detection means 676 are sent to a control means (not shown), and the control means controls the main drive source based on the transfer state of the preform as follows. That is, in the specific example, in relation to the crankshaft 26 (FIG. 2), an angular position detection means (not shown) for detecting a specific angular displacement t (for example, a rotational angular position of approximately 15 degrees) of the crankshaft 26 is used. ) is arranged, and the angular position detecting means is the crankshaft 2.
6 is rotated to the specific angular position, a signal is generated and sent to the control means. On the other hand, when the crankshaft 26 rotates to the specific angle position, the transfer mechanism 6
02, each preformed body is transferred as described above and passes over each preformed body detection means 676.

Therefore, each preformed body detection means 676 detects the preformed body being transferred and sends the detection signal to the control means. As can be easily understood, the control means determines that when all the preformed body detection means 476 generate detection signals at the same time as the angular position detection means generates the signal, the preformed body transfer state is normal; Therefore, the main drive source continues to operate, and the transfer press equipment continues to operate normally).
Simultaneously with the signal generation of the angular position detection means, at least one of the preformed object detection means 476 does not generate a detection signal (in other words, there are places where the preformed object is not gripped as required between the gripping claws 616). Sometimes the state of transfer of the preform is abnormal, and therefore the operation of the main drive source is stopped (therefore, the operation of the transfer press apparatus is stopped). The main drive source may be stopped immediately when the preformed body detection means 676 does not generate a detection signal, or may be stopped after a predetermined period of time has elapsed.

In the transport defect detection means having the above-mentioned configuration, since a proximity switch is used as the preformed object detection means, even if the preformed object is transferred at high speed, it can be reliably detected, and molding can be performed at high speed. Suitable for transfer press equipment that performs processing.

Transfer Press Expo. The transfer press device described above performs punching in the pre-processing area P of the sub-press section 4, and then performs the punching process in the transfer processing area T of the transfer press section 6 to TI! However, instead of this, drawing processing is performed along with punching in the pre-processing area P of the sub-press section 4, and further drawing processing is performed in the subsequent transfer processing areas TI to T''+t. Alternatively, drawing and ironing may be performed. In such a case, a short cylindrical preformed body, for example, is formed in the preprocessing area P, and due to this, the idle area 11 to The 4th neighborhood is shown in Figure 27 and 2.
It can be configured as shown in FIG. Holding means 338

In addition, the holding member 704a
A pin member 716 that protrudes downward is implanted at the other end of 704b, the upstream end when viewed in the direction indicated by arrow 706, and on the inner surface of this pin member 716 (the side facing support plate 708). A notch is formed. On the other hand, the support plate 70
A recess 718 is formed on the side surface facing the pin member 716 of No. 8, and a spring member 720 is housed in the recess 718.
One end of the spring member 720 is locked to the pin member 716. As shown above, each case member 7
04a (or 704b) is elastically biased clockwise (or counterclockwise) in FIG. 27 by the action of the spring member 720, and is normally held at the position shown in FIG. 27 (in such a state, As will be readily understood, transport of the preform is permitted between the upstream ends of the pair of retaining members 704a and 704b).

Further, in FIG. 28, which shows a part of a modified example of the transfer mechanism 602 in an enlarged manner, in the specific example described above, the butcher plate 72 is provided corresponding to the pre-processing area P, and each idle area (2).

Each sliding member 724 has substantially the same configuration as the gripping claw 616 of the specific example described above except for the claw portion 630, and
16 to transfer bars 604a and 604b. Then, the sliding member 7 attached to the transfer bar 604a (or 604b)
A gripping member 722a (or 722b) is attached between the 24 with a mounting screw 726. Gripping member 722
A and 722b have four arcuate gripping portions 730a, 730b spaced apart from each other in the direction shown by arrow 706 on the inner surfaces thereof.
730c and 730d are formed. These gripping members 722a and 722b are connected to the transfer bar 604a.
When the above-described return movement of 722a and 604b is completed, the gripping members 722a and 722b are positioned at the position shown in FIG.
grip part 730a (or 730b, 730c, 730
゛(d) is the pre-processing area P (or idle area 11 + I
t+Is).

Next, the effects of the above-mentioned configuration will be explained.
It is as follows.

It will be understood from the above description that when the opening/closing bar (see FIGS. 22 and 23) is moved in the direction opposite to the direction indicated by arrow 706 relative to transfer bars 6043 and 604b in transfer mechanism 602, Ru like (
, gripping members 722a and 722 via sliding member 724.
The gripping member 722a is moved in the gripping direction in which b is inside, and the gripping member 722a
and 722b are positioned at the working position and are connected to the pre-processing area P and the idle area 1. The preforms present at points I to I are gripped as required.

Next, transfer bars 604a and 604b are moved in the direction indicated by arrow 706, and when the forward movement is completed,
The preformed body held between the gripping members 722a and 722b is transferred to the next area as required (for example, the preformed body that was in the preprocessing area P is sent to the idle area (2)). The preformed body is transferred between the holding members 704a and 704b in FIG. 27. Therefore, at the beginning of the transfer, gripping members 722a and 722b
The holding member 70 is moved by the movement of the preformed body held therebetween.
4a and 704b are pivoted against the elastic biasing force of the spring member 720, thus releasing the holding of the preform by the holding members 704a and 704b as desired. Further, at the end of the transfer, the holding members 704a and 704b are rotated against the force of the spring member 720 by the passage of the preformed body, and then are rotated in the opposite direction to the rotation direction by the action of the spring member 720, Thus, the holding members 704a and 704b hold the transferred preformed body in their gripping portions 71.
5. Grip elastically between the two.

After that, the opening/closing bars 606a and 606b move toward the arrow 70 relative to the transfer bars 604a and 604b.
6, the gripping members 722a and 722b are moved outward through the sliding member 724 in the opening direction and are positioned at the retracted position shown in FIG. , the gripping of the preformed body by the gripping members 722a and 722b is released. In this way, the transferred preformed body is elastically and reliably held between the holding members 704a and 7046 in the idle areas 1 to 14. In the specific example, since the gripping members 722a and 722b are arranged slightly above the holding members 704a and 704b, the holding members 704a and To"4b
holds the lower part of the preformed body, and the gripping members 722a and 72
2b comes to grip the upper part of the preformed body.

If the above configuration is adopted, the preformed body can be reliably held in the idle areas ① to I4 with a relatively simple configuration, and the preformed body can be transferred as required. Regarding this transfer, the pusher plate 72 and the mechanism for reciprocating it in the above specific example can be omitted.
