Detailed Description of the Invention [Object of the Invention] (Industrial Application Field) The present invention relates to a press that presses a workpiece placed between a punch and a die by pressing the punch with a pressing mechanism, such as a cylinder mechanism. Regarding equipment.

(Prior Art) With the corresponding molds of a punch and a die each supported by a support member, and a workpiece to be processed being placed between the punch and the die, the punch is punched by a cylinder mechanism placed above the punch. A press device is known that presses a workpiece by pressing downward. FIG. 8 explains such press working, where 1 is a workpiece to be machined, 2 is a punch fixed to a punch holder 3 and placed above the workpiece 1, and 4 is a punch fixed to a die boulder 5 and attached to the workpiece 1. The die 6 arranged on the lower side is a cylinder mechanism to which a bolt-like rod 7 is attached.

When pressing a workpiece with such a press device, the workpiece 1 is usually pressed in the X and Y directions.
As shown in FIG. 9, a large number of processed holes la, lb, lc, . . . are formed by repeating pressing in the same direction. For pressing here, before placing the workpiece 1, the punch 2 which is the upper die and the hole 4 of the die 4 which is the lower die.
It is necessary to perform alignment with a, so-called type alignment.

To perform die matching, first, the punch 2 is roughly lowered together with the cylinder mechanism 6, and then the die 4 is moved horizontally in the X and Y directions by the die holder 5 to position it. Opposing die 4
This is done by moving up and down on the top to make fine adjustments. Here, fine adjustment of the vertical movement of the punch 2 is performed by inserting an adjustment bar 8 into the horizontal hole 7A of the bolt-shaped rod 7 that supports the punch 2 at the tip, and rotating the adjustment bar 8, as shown in FIG. This is done by moving the punch holder 3 up and down.

(Problems to be Solved by the Invention) In conventional press devices, the vertical movement of the punch is finely adjusted by rotating a bolt-like rod. but,
During the press operation, a load of several tons is applied, so the bolt-like rod is constructed to be large in order to withstand this load. Therefore, there is a problem in that it is difficult to rotate such a large bolt-like rod.

Furthermore, during press working, all of the press pressure is applied to the bolt-like rod, making it susceptible to fatigue.

The present invention has been made in response to the above-mentioned problems.
It is an object of the present invention to provide a press device that allows easy fine adjustment of the vertical movement of a punch when performing die matching, and that also allows for miniaturization of the device.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a method for disposing a workpiece between a punch and a die, each of which is supported by a support member, and providing a workpiece above the punch. In a press device that presses a workpiece by pressing a punch downward with a pressing mechanism, the pressing mechanism is arranged between the pressing mechanism and the punch, contacts at least one of them via a tapered surface, and is movable in a horizontal direction. The present invention is characterized in that it includes a height adjustment member, and by moving the height adjustment member in the horizontal direction, the tapered surface is moved to finely adjust the vertical movement of the punch.

(Function) A height adjustment member is disposed between the pressing mechanism and the punch so as to be in contact with at least one of the two via the tapered surface, and by moving this height adjustment member in the horizontal direction, the taper is adjusted. moving said contact surface of the surface; As a result, the distance between the pressing mechanism and the punch can be changed, so that the vertical movement of the punch can be finely adjusted.

(Example) The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a side view showing an embodiment of the press device of the present invention.
1 is a workpiece to be processed; 2 is a punch fixed to a punch holder 3 and placed above the workpiece 1; 4 is a die holder 5
A die 6 fixed to and arranged below the workpiece 1 is a cylinder mechanism to which a rod 27 is attached.

Reference numeral 9 denotes a height adjusting member disposed between the rod 27 and the punch holder 3, and is used to finely adjust the vertical movement of the punch 2 when performing die matching.

FIG. 2 shows only this height adjusting member 9 taken out. Further, FIG. 3 shows an exploded view of this height adjusting member 9. As shown in FIG. As is clear from Figures 2 and 3,
The height adjustment member 9 includes a movable body 10 having a screw hole 10A in the horizontal direction and a tapered surface 10B on the upper surface, and a U-shaped first side plate 11 fixed to both side surfaces of the movable body 10. and the second side plate 12 and the tapered surface 1 of the moving body 10
It is composed of a convex upper plate 13 that is slidably in contact with the lower surface 13C of the movable body 10, and a reversely convex lower plate 14 that is slidably in contact with the lower surface 10C and the lower surface 14C of the moving body 10. where each upper piece 11 of the first and second side plates 11.12
A, inner surfaces 11B, 12B of 12A and both side stepped surfaces 13A of the upper plate 13.

13B and the lower surface 13C are each formed with a tapered surface having the same shape as the tapered surface 10B of the movable body 10, so that the inner surface 11B, the stepped surface 13A, and the inner surface 12B
and the stepped surface 13B are configured to be slidable.

Further, the upper surface 13D of the upper plate 13 is fixed to a rod 27 as shown in FIG. 1, and the upper surface 14D of the lower plate 14 is fixed to the punch holder 3. As a result, the rod 27 can only move up and down, so the upper plate 13 and the lower plate 14 are also configured to move only up and down. On the other hand, the movable body 10 is not shown in FIG. 1, but as described later, a lead screw is screwed into the screw hole 10'A of the movable body 10, so that the movable body 10 can move in the horizontal direction integrally with the side plates 11 and 12. is configured to allow. Therefore, when the movable body 10 moves in the horizontal direction, the contact position between the tapered surface 10B of the movable body 10 and the lower surface 13C of the upper plate 13 is at the tapered surface 10B.
, the height position of the upper plate 13 changes. As a result, the distance between the rod 27 and the punch holder 3 changes, making it possible to finely adjust the vertical movement of the punch 2.

FIG. 4 shows the horizontal movement mechanism of the movable bodies 1 and 0. An L-shaped holder member 15 is fixed to the end of the lower plate 14, and a vertical plate 15A of this holder member 15 has screws. An insertion hole 15C is provided, and this screw insertion hole 1
A lead screw 16 is screwed into the screw hole 10A of the movable body 10 via the screw 5C. Figure 5 shows holder member 1
FIG.

A rotation operation part 17 for rotating the lead screw 16 is provided on the left side of the lead screw 16 in FIG. Large diameter flange 19
and a small diameter flange 20 which is integrally connected to the large diameter flange 19. Further, a guide hole 21 for guiding the left end of the lead screw 16 is provided inside the large diameter flange 19 and the small diameter flange 20.
A spring 22 is interposed between the left end of the lead screw 16 and the side wall of the large diameter flange 19. Normally, due to the biasing force of the spring 22, the rotation operation section 17 is located at the leftmost position as shown in the figure.

On the left side of the vertical plate 15A of the lead screw 16 is a pair of pins 23A, as shown in FIG. 6(a).

23B, and on the side wall of the small diameter flange 20, a pair of grooves 24A, 24B are provided for engaging the pair of pins 23A, 23B. Each of these pins 23A, 23B is connected to a groove 24A.

24B, the small diameter flange 20 is locked to the lead screw 16, and if the handle 18 is rotated in this state, the lead screw 16 will rotate and can be moved horizontally (forward or backward). Become.

A spring pin 25 is provided on the horizontal plate 15B of the holder member 15, as shown in FIG. 6(b). On the other hand, a stopper groove 26 is provided around the small diameter flange 20, as shown in FIG. 6(C), and a spring pin 25 is configured to be able to be locked in this stopper groove 26. When the rotary operation unit 17 is at the leftmost position as shown in FIG.
A spring pin 25 is locked in the stopper groove 26, and when in this locked state, the handle 18 of the rotary operation section 17 is positioned upward so that it does not get in the way during the press operation. If the small diameter flange 20 is moved from the position shown in FIG. 4 to the right against the biasing force of the spring 22, the locked state is released and the handle can be rotated.

Next, the operation of this embodiment will be explained.

As shown in FIG. 4, when the rotation operation part 17 is in the leftmost position under the force of the spring 22, the spring pin 25 of the horizontal plate 15B is engaged with the stopper groove 26 of the small diameter flange 20, and the lock state is reached. , the handle 18 is positioned upward and cannot be rotated.

Further, the contact state of the lower surface 13C of the upper plate 13 and the contact state of the lower surface 14C of the lower plate 14 of the height adjustment member 9 with the tapered surface 10B of the movable body 10 in FIG. 2 has a relationship as shown in FIG. 7(a). It is in. At this time, the upper surface of the upper plate 13 and the lower plate 1
4, that is, the distance between the rod 27 and the punch holder is Dl.

Next, when fine-tuning the vertical movement of the punch, as shown in FIG. 26 and spring pin 2
5 is released, and the pair of pins 23A and 23B are inserted into the groove 24A of the small diameter flange 20 by moving further to the right.
.

24B. As a result, the small diameter flange 20 is locked to the lead screw 16, and in this state, the handle 1
By rotating 8, the lead screw 16 is screwed into the screw hole 10A of the movable body 10 of the height adjusting member 9, and can be moved forward or backward.

For example, if the handle 18 is operated to rotate the lead screw 16 in the backward direction (to the left in FIG. 4), the movable body 10 will move to the right in opposition to this, and the tapered surface of the movable body 10 13 will move to the right. Therefore, the contact state of the lower surface 13C of the upper plate 13 and the contact state of the lower surface 14C of the lower plate 14 change as shown in FIG. 7(b), and the distance D1 in FIG. 7(a) is changed.
will now decrease to D2. Therefore, the lower plate 14 rises, and the punch holder 3 connected thereto moves upward.

If the handle 18 is operated in the opposite direction, the lead screw 16 moves forward, the movable body 10 moves to the left, and the tapered surface 13 moves to the left. Therefore, in this case, the distance D1 in FIG. 7(a) increases to D3 (not shown). Therefore, the punch holder 3 moves downward.

As described above, according to the present embodiment, by operating the rotary operation section 17, the lead screw 16 is moved forward or backward, and the movable body 10 is moved in the horizontal direction. First. Second side plate 11,1
2 moves, the vertical movement of the lower plate 14, the punch holder 3 and the punch 2 connected thereto can be easily finely adjusted. After making fine adjustments to the appropriate height position, return the nozzle 18 to the left position as shown in Figure 4, and the handle 18 of the rotary operation section will be locked upwards, so it will not get in the way. Since the lead screw 16 is also unlocked, the fine adjustment state will not be impaired even if a shock is applied to the handle by mistake.

If the handle is operated only when fine adjustment of the vertical movement is desired, and the handle and lead screw 16 are left unrelated at other times, the handle 18 will not move due to vibrations generated during punching. Malfunctions such as the lead screw 16 rotating against one's will can be prevented. Therefore, fine adjustment of the vertical movement of the punch can be performed accurately.

In addition, since the rod 27 and the height adjustment member 9 are in surface contact, the press pressure during press working is not entirely applied to the threads as in conventional equipment, but is dispersed over the surface. The height adjustment member 9 can be configured to be compact, and the entire device can be made compact. Fatigue is reduced. Furthermore, the life of the height adjusting member can be extended.

In the description of the embodiments in this text, only the basic configuration of the device is shown, and various additional parts will be installed in the actual device, but the basic operation will not change in any way. Further, the position of the tapered surface is not limited to the position shown in the embodiment.

[Effects of the Invention] As described above, according to the present invention, since horizontal movement is changed to vertical movement using the tapered surface, fine adjustment of the vertical movement of the punch when performing die matching can be easily performed. It can be carried out. Further, it is possible to provide a punching device that can be miniaturized.
