Description

[Detailed description of the invention] This invention has a mechanism to automatically remove scraps or products remaining in the lower mold when trimming etc. are performed by press working, and also to take out the products or scraps removed from the upper mold to the outside. The present invention relates to a press device equipped with a mechanism.

Automation of press equipment has been promoted in recent years, and this has had great effects in increasing production volume, saving labor costs, and improving product precision.

Automation of press equipment is indispensable, especially when producing products in an integrated process together with other equipment.

Conventionally, a type of automated press equipment is equipped with an auxiliary bed provided at one end of the bed of the main body and rotated by a rotational drive mechanism, which is provided following the bed, and a bolster to which a lower die is fixed is attached to the bed and the auxiliary bed. The lower mold, which is placed so as to be able to reciprocate on the bed and has scraps left behind from press work such as trimming, is moved onto the auxiliary bed together with the bolster, and then the bolster is rotated together with the auxiliary bed to remove the lower mold. There was one to remove the remaining scrap.

However, with the conventional device described above, if the rotation drive mechanism is activated before the bolster moves onto the auxiliary bed and reaches the predetermined position, the rotation centers of the bolster and the auxiliary bed do not coincide, resulting in However, there is a disadvantage that excessive force is applied to the drive cylinder and piston rod that move the bolster, causing damage.Also, even if the bolster rotates correctly with the auxiliary bed, if the scrap is not removed from the lower mold in a timely manner, it will be scrapped. There was a drawback that the next pressing step was carried out with the particles remaining in the lower die, causing damage to the product or equipment.

The above disadvantages include the provision of a locking mechanism that allows rotation of the bolster and auxiliary bed only when the rotation center axis of the bolster and the rotation center axis of the auxiliary bed match, and that the auxiliary bed and bolster can be rotated to a predetermined position. The problem was solved by providing a fixed protrusion that automatically ejects the product or scrap from the lower mold when the mold is moved.

However, in order to take out the product removed as described above, it is common to install an inclined chute and drop the product diagonally down the chute, which has the disadvantage that the product is easily damaged.

The purpose of this invention is to provide a press device that is equipped with a known press device having the above-mentioned locking mechanism and the above-mentioned fixing protrusion, as well as a sending mechanism that moves the crushed product or scrap in a horizontal direction and sends it to the next process. It is in.

Next, an embodiment for achieving the above object will be described.

Figures 1 to 5 show the press apparatus. This press device automatically trims a molding 10 (FIG. 1) formed by a die-casting device (not shown) and sent automatically, and further produces a product 12 (FIG. 5) by trimming. and scrap 14 (FIG. 5) are automatically removed.

The main body 16 of the press apparatus opens in the left-right direction in FIG. 1, and a bolster 20 that can be moved left and right is placed on a bed 18 of the main body 16.

An upper die 24 is attached to the lower end of the ram 22 of this press device.

is fixed.

As shown in FIG. 1, the molding material 10 formed by the die-casting device is placed on the lower mold 26, and the lower mold 26 is moved under the upper mold 24 as shown in FIG. 4 by the movement of the bolster 20. After the ram is moved, the above-mentioned plastic surgery 10 is trimmed by the vertical reciprocating motion of the above-mentioned ram.

A transfer mechanism 28 for moving the bolster 20 is mounted on the bed 18 of the main body 16, and the mechanism 28 has a pair of guide rails 30, 30 made of a hexagonal polished steel bar (the third
figure).

The guide rail 30°30 fits into a groove 32°32 (FIG. 2) formed on the lower surface of the bolster 2, and
is guided in the left or right direction shown in FIG. 1, that is, in the direction A or B shown by the arrow.

The transfer mechanism 28 also has a drive cylinder 34 for moving the bolster 20 disposed on the bed 18, and the cylinder 34 moves the bolster 20 in directions A and B in FIG. 1 via a piston rod 36.

A bolster 20 is supported at the right end of the piston rod 36 so as to be rotatable about a rotation shaft (not shown) provided perpendicular to the plane of the paper of FIG.

When trimming is performed to a molding amount of 10 using the upper die 24 and the lower die 26, the product 12 or scrap 14 is usually placed on the upper die.
remains attached and remains on the lower mold, scrap 14 or product 12
remains attached.

The type in which the scrap 14 remains in the product 12 is determined based on the type of product, the work process, etc., but even if the scrap 14 remains in either type, it does not affect the essence of the present invention. As shown in FIG.
The explanation will be made assuming that the product 12 remains on the side of the mold 26 and the scrap remains on the side of the lower die 26.

However, in FIG. 5, a feed plate 52 and related parts of the product delivery mechanism 40, which will be described later, and a product receiving plate 53, which are not directly related to the explanation given using this figure, are omitted.

Reference numeral 40 denotes a delivery mechanism that is attached to the upper die 24 and sends out the product 12 removed by the product delivery cylinder 17 to the outside of the press device, that is, in this case, a product delivery mechanism.

A chute support member 44 belonging to the mechanism 40 and supporting the chute 42 substantially horizontally is connected to the bolster 20 and driven by the drive cylinder 34 to move along the guide rail 30.30 in the directions A and B in FIG. Can be moved.

The chute 42 is a flat channel-shaped member that is open to the left end in FIG. 1 and upwardly.

Above the chute 42, there is provided a mechanism that belongs to the product delivery mechanism 40, is attached to the main body 16, and sends the product 12 placed on the chute 42 in the direction A in FIG.

The mechanism consists of an air cylinder 46, a box 49 that is connected to a piston rod that cooperates with the air cylinder 46 and moves up and down and opens downward, and guide members 48, 48 that guide the up and down movement of the box 49. Become.

The box body 49 includes a horizontal member 50 and a feed plate 52 extending downward from the periphery of the horizontal member 50.

As shown in FIG. 1, on the left side of the chute 42, a receiving plate, in this case a product receiving plate 53, is attached to the main body 16, and is disposed at a position lower than the chute 42 and substantially horizontally adjacent to the chute 42.

As will be explained later, the product 12 dropped from the upper mold 24 is
Due to the horizontal movement of the chute 42 and the vertical movement of the box body 49, the product is moved leftward on the chute 42 and transferred onto the product receiving plate 53, and further pushed leftward by the movement of the chute 42, so that the next product is It is sent to a mechanism such as a machine tool or a packaging device (not shown).

Figures 10a to 10f show the box 49 shown in Figure 1.
and the movement of the chute 42, the product 12 (No. 1
and No. 2) are sent out to the left of the figure in order.

Since the figure is for explaining the movement of the product, only main related members such as the box body 49, the chute 42, the product receiving plate 53, and the product 12 are shown.

In FIG. 10a, the box 49 is in the lowered position, the chute 42 is in the right position, and there are two products 12 (No. 1).

2) shows the state in which the product 12 is dropped from the upper die onto the chute 42 (hereinafter, to distinguish between the products 12, 2)

will be moved to

Next, a modification 40a of the above-described product delivery mechanism 40 will be described with reference to FIGS. 11a to 11f and 12a to 12c.

These figures also show only important points, similar to Figures 10a to 10f.

This mechanism 40a includes a pair of guide plates 51 on the chute 42.
．． 51 is provided, which is different from the mechanism 40 described above.

The guide plate 51.51 is connected to the chute 42 as shown in the above figure.
It is located on the left side of the road, spreads to the right, and runs parallel to the left.

Movement of the box body 49 and chute 42 and accompanying product N
The left and right movements of o, 1~No, 6 are as follows: 10a~
Since this is the same as in the case of FIG. 10f, explanation regarding the movement will be omitted.

However, in this case, product no. 1 to No. 096, etc. are sequentially lined up and sent one after another to the left, so this point will be mainly explained.

Figures 12a, 12b, and 12e are the 11th
Fig. C, Fig. 11d, and Fig. 11e are viewed from above, and Fig. 12a, that is, Fig. 11C shows the product defect.

1, No. 2, and 2 are pushed into the parallel part between the guide plates 51 and 51 while in contact with the right feed plate 52 and aligned in a certain direction. In FIG. 12b or FIG. 11d, product No. The relative positions of 1 to No. 4 and the chute 42 and guide plate 51, 51 do not change, and new product No.
3, No. 4 are placed directly under the box body 49.

In Figures 12c and 12e, the product side. 1.No
, 2 (indicated by two-dot chain lines) are pushed by the products No. 3, No. 4, and are pushed out from the left end of the chute 42 in an aligned state, and the products No. 3, No. 4 are guided instead. It enters the parallel part between the plates 51.51 and is aligned in a certain direction.

As described above, in the operation of the product delivery mechanisms 40 and 40a, although the product numbers are different in FIGS. 10e and 10c and FIGS. 11e and 11c, they are in substantially the same operating state, and FIG. Continuing from Figure 11e,
By moving the box 49 up and down according to the above-mentioned idea and moving the chute 42 left and right accordingly, the products can be sent out one after another toward the device 55.

With these product delivery mechanisms 40, 40a, the product is moved almost horizontally, and the downward movement can also be performed with a small drop, so that the product can be delivered without damaging the product.

The products No. 1 to No. 6 are transferred onto the chute 42 by driving the ejecting cylinders 17 and 17 provided on the ram 22 shown in FIGS.
This is done by ejecting the product adhering to 4.

Further, at the right end of the main body 16 (FIG. 1), there is provided a take-out mechanism for removing the scrap 14 remaining on the lower mold 26 after the trimming process, that is, a scrap take-out mechanism 54 in this case.

The scrap removal mechanism 54 is located on both sides of the right end of the bed 18, that is, at a position spaced apart in a direction perpendicular to the paper surface of FIG.
A pair of bearing members 56, 56 (Fig. 1, Fig. 2, Fig. 3,
8, 9, etc.).

Between the bearing members 56, 56 is an auxiliary bed 58 (a first
8, 9, etc.) is rotatably supported by a rotating shaft 38 attached to the bearing members 56, 56.

The auxiliary bed 58 is rotated by a rotational drive mechanism 61,
The lower side of the auxiliary bed 58 has a bolster rotation cylinder 6.
0 piston rod 62 is provided with its upper end rotatable relative to the auxiliary bed 58.

The cylinder 60 is also mounted on the main body 16 so as to be rotatable about an axis (not shown) parallel to the rotation axis 38.

When the piston rod 62 extends from the cylinder 60 due to the action of the bolster rotation cylinder 60, the auxiliary bed 58 rotates clockwise about the rotating shaft 38, and the piston rod 62 is pulled into the cylinder 60. Then, the auxiliary bed 58 rotates counterclockwise about the rotating shaft 38.

On the auxiliary bed 58, a pair of auxiliary guide rails 64.
64 (Fig. 2) are bored, and these auxiliary guide rails 64
．． 64 guides the bolster 20 onto the auxiliary bed 58.

When the bolster 20 is moved onto the auxiliary bed 58 by the action of the drive cylinder 34, the pivot axis of the bolster 20, which is rotatably attached to the right end of the piston rod 36 of the drive cylinder 34, is aligned with the support member 56.56. It is formed to coincide with the rotation center shaft 38 attached to the.

Further, guides 68°68 having engaging grooves 66 and 66 are integrally provided on both edges of the upper part of the auxiliary bed 58, while engaging protrusions 68 and 68 are provided on the bolster 20 in correspondence with the guides 68 and 68, respectively. 70,70 are drilled.

Since the engaging protrusions 70, 70 are slidably engaged with the engaging grooves 66, 66, when the bolster 20 is moved from side to side in FIG. It never wavers.

Lock mechanisms 72 (FIGS. 1, 6, and 7) are attached to both sides of the auxiliary bed 58.

The mechanism 72 has a pair of locking rods 74, 74, which rise at a base 76 formed along the bottom surface of the auxiliary bed 58 and at the right side of the auxiliary bed 58, respectively, and at the upper end of the auxiliary bed 58. It has a protrusion 80 that protrudes from toward the bolster 20.

Further, the base 76 of the lock rod 74 has a locking protrusion 82 (sixth
(Fig. 7) are drilled.

The locking protrusion 82 and the base 76 are guided by mounting members 84 and 86 attached to the lower side of the auxiliary bed 58, respectively, and are formed to be movable in the direction along the auxiliary guide rails 64 and 64.

A compression coil spring 88 is interposed between the mounting member 86 and a stepped portion formed at a portion connecting the engagement protrusion 82 and the base 76, and the lock rod 74 protrudes toward the bed 18 due to the action of the spring 88. (Figure 6).

When the locking rod 74 protrudes toward the bed 18 as described above, the locking protrusions 82, 82 engage with the bottom surface of the bed 18 and lock the auxiliary bed 58 from rotating clockwise.

However, when the bolster 20 is moved to the right in FIG. 1 and hits the protrusion 80, the locking rod 74 is moved to the right against the compression coil spring 88, and the locking protrusion 82 is retracted to the right. The rotation of the auxiliary bed 58 is unlocked.

As shown in FIG. 8, each of the support members 56, 56 is provided with a fixing protrusion 90 that protrudes to the right (only one is visible in FIG. 8).

A pair of extrusion pieces 92 and 94 are attached to both sides of the bolster 20 at positions facing each of the fixing protrusions 90, 90.

One end of each of these extruded pieces 92 and 94 is connected to a pin 96.
．． It is rotatably attached to the bolster 20 at 96.

A hole (not shown) is formed at the other end of each of the extruded pieces 92 and 94, and these holes are loosely connected by a pin 98.

Note that one of the holes drilled in the other end is the extrusion piece 9.
2 and 94 are formed into elongated holes so that they can rotate at a predetermined angle about pins 96 and 96.

As shown in FIG. 8, the lower mold 26 is provided with a plurality of ejection holes 100 passing through it in the vertical direction.

Furthermore, there is a gap 102 between the lower die 26 and the bolster 20.
is provided, into which a springing member 104 is inserted.

A plurality of push-out pins 106 are installed in the push-out member 104 facing the push-out hole 100, and these pins 1
06 is adapted to protrude from the surface of the lower mold 26 by the movement of the protrusion member 104 toward the upper mold 24.

Therefore, when the bolster 20 rotates together with the auxiliary bed 58, the fixed protrusion 90 pushes the other end of one extrusion piece 94 toward the lower die 26, and the extrusion pieces 92 and 94 cooperate to expel the extrusion member. 104 toward the lower mold 26.

Therefore, the push-out pin 106 projects outward from the lower mold 26 and serves to remove the scrap 14 adhering to the lower mold 26 from the lower mold 26.

Next, the operation of the press device configured as described above will be explained.

The molded product 10 molded by a die-casting device (not shown) is
It is placed on the lower mold 26 located to the right of the upper mold 24 (FIG. 1).

The piston rod 36 is then retracted into the drive cylinder 34 and the chute support member 4 connected to the piston rod 36
4 and the bolster 20 are moved to the left or in the direction A along the guide rail 30.30 to the position shown in FIG.

When the chute support member 44 finishes moving in the A direction, the feed plate 52 guided by the two guide members 48° 48 is moved downward by the air cylinder 46 and comes into contact with the chute 42 and stops.

A product 12 formed by trimming the molded product 10 is placed on the chute 42, as will be described later, and is located between the feed plates 52.

Due to the movement of the chute 42 in the direction A, the products 12 that have already been transferred onto the product receiving plate 53 are removed from the chute 42.
is pushed to the left on the product receiving plate 53 and sent to another device (not shown) for processing the product, such as a product storage device.

In the position shown in FIG. 4 where the bolster 20 has moved in the direction A, the lower die 26 fixed to the bolster 20 is moved by the ram 22.
It occupies a position opposite to the upper mold 24 fixed to.

Therefore, if the upper mold 24 is lowered at a position where the upper mold 24 and the lower mold 26 face each other, the molded product 1 placed on the lower mold 26 will be removed.
0 is trimmed.

When the ram 22 is raised again, the product 12 formed by the trimming remains on the upper mold 24 and the scrap 14 formed by the trimming remains on the lower mold 26.

After the ram 22 is raised, the piston rod 36 protrudes from the drive cylinder 34 and the chute support member 4
4 and the bolster 20 to which the lower die 26 is fixed is moved in the direction of arrow B.

The product 12 on the chute 42 is blocked by the feed plate 52 and
It cannot move in this direction, but moves to the left with respect to the chute 42 by the movement stroke of the chute 42.

At the position shown in FIG. 1 where the movement of the chute 42 in the direction B is completed, the position of the chute 42 facing the upper die 24 is in an open state.

Therefore, by driving the product ejection cylinder 17, the product 12 attached to the upper mold 24 can fall onto the chute 42 without being disturbed.

At this time, the feed plate 52 is moved upward by the action of the air cylinder 46, and the product 12 that has newly fallen onto the chute 42 is driven by the drive cylinder 34 and transferred to the chute 42.
2 moves in the A direction, it can move in the A direction without being hindered by the feed plate 52.

As mentioned above, when the chute 42 moves in the B direction by the action of the drive cylinder 34, the bolster 20 also moves in the B direction.
moving in the direction from the guide rail 30.30 on the bed 18 to the auxiliary guide rail 64.64 on the auxiliary bed 58.58.
Shift upward and push the protrusions 80, 80 of the lock rod 74 forming the lock mechanism 72 to the right.

Therefore, the protrusions 80, 80 and therefore the locking rods 74, 7
4 and the locking protrusion 82.82 are compressed coil springs 88.
The locking protrusions 82, 82, which had been engaged with the lower surface of the bed 18 and locked the rotation of the auxiliary bed 58, are moved to a position where they are removed from the lower surface of the bed 18. This allows the auxiliary bed 58 to rotate, thereby allowing the scrap removal mechanism 54 to operate.

At this time, as shown in FIGS. 5 and 9, the bolster rotation cylinder 60 is driven and the piston rod 62 is projected upward, and the bolster 20
It is rotated in the direction of the arrow in FIGS. 8 and 9 about a rotation axis that is coaxial with .

At this time, the fixing protrusion 90 drilled in the support member 56, 56
, 90 push the push-out pieces 92, 94 in the direction B (FIGS. 5 and 9), causing the push-out member 104 and therefore the push-out pin 106 to project to the right.

Therefore, the ejector pin 106 hits the scrap 14 attached to the lower mold 26, removes it, and drops it into a suitable scrap receptacle (not shown).

When the scrap 14 is removed as described above, the bolster rotation drive cylinder 60 is driven, the auxiliary bed 58 is rotated in the opposite direction to the above-mentioned upward direction, and the bolster 20 and the lower die 2 are rotated.
6 returns to the horizontal position.

When the bolster 20 returns to the horizontal position as described above, the operation of the drive cylinder 34 causes the bolster 20 and the chute 42 to be moved again in the A direction, and the locking rod 14.14 is moved in the A direction by the action of the helical compression springs 88, 88. Move to.

Therefore, the locking projections 82,82 are attached to the peds 18 of the main body 16.
It engages with the lower surface and prevents the auxiliary bed 58 from rotating.

That is, the auxiliary bed 58 and the scrap removal mechanism 54
is locked.

When the bolster 20 and the chute 42 move further in the direction A, the plurality of products 12 that have been trimmed in the previous process and have been dropped onto the chute 42 are sequentially fed out of the device as described above.

As mentioned above, the bolster rotation drive cylinder 60, the drive cylinder 34, the ram 22, and the product ejecting cylinder 17
By sequentially operating these using a limit switch (not shown) or the like, the trimming work can be performed automatically.

Therefore, by using the press device of this invention in combination with a die-casting device and a device that sends the molded product 10 manufactured by the die-casting device to this press device, the entire process for permeating the product 1 can be automatically carried out. I can do it.

At this time, the rotation of the auxiliary bed 58 and the bolster 20 and the operation of the scrap removal mechanism 54 are controlled by the lock mechanism 72.
As a result, rotation of the bolster 20 at an incorrect position may cause a failure in related mechanisms. Moreover, the inconvenience that the scrap 14 is not completely removed does not occur.

Further, in the case where the fixed protrusions 90, 90 are provided on the bearing members 56, 56 as in this embodiment, the fixed protrusions 90, 90 are pushed off via the extruded pieces 92, 94 when the bolster 20 is rotated. The extrusion member 104 is extruded, and the scrap 14 is placed in the lower mold 2.
6, the scrap 14 can be taken out very reliably, and there will be no inconvenience such as the scrap 14 being partially stuck to the lower die 26 during the next press process.

In a press machine having a locking device which, upon movement, draws the locking protrusion from the lower part of the bed into the lower part of the auxiliary bed, allowing rotational movement of the auxiliary bed and the bolster; Between the highest position of the upper die and the bed, a receiver is attached to the piston rod of the transfer mechanism to hold the press molded product removed from the upper die on the upper surface, and the piston rod is moved with the same stroke, a chute that is driven to reciprocate in the delivery direction and the opposite direction at the same time as the bolster; a product delivery mechanism supported on the delivery direction side of the ram and above the chute so as to be movable up and down; The product delivery mechanism includes a box body having a delivery direction side feed plate and a reverse direction side feed plate which are spaced apart from each other by approximately the same distance as one stroke of the piston rod of the transfer mechanism in the moving direction of the chute. , the box body moves the chute in the delivery direction at a position where the distance between the opposite direction side feed plate and the opposite end of the press molding taken out on the chute is approximately equal to one stroke of the piston rod. When moved, the feed plate is moved to a high position where it does not come into contact with the forming technique on the chute, and when the chute is moved in the opposite direction, the feed plate is moved to a high position where it does not come into contact with the forming technique on the chute, and when the chute is moved in the opposite direction, the feeding plate abutting and moving the former in the delivery direction relative to the chute, so that each reciprocating movement of the chute causes the former on the chute to move approximately 1 in the delivery direction.
A press device that is characterized by being fed out in strokes.
