2. Description of the Related Art C type frame press is
A generic term for a press machine in which a bolster (table) for fixing the lower mold is supported on the lower arm of the frame of the mold, and a ram (slide) for fixing the upper mold that moves back and forth with respect to this bolster is supported on the upper arm. The reaction force of processing is received by the upper arm and the lower arm of the C-shaped frame. This C-type frame press has a characteristic that it has better workability than a straight side frame press, but on the other hand, since the frame is C-shaped, the frame is easily deformed (easily opened) due to the load during processing. The deformation of the C-shaped frame causes a change in the direction of up-and-down movement of the ram (upper die) with respect to the bolster (lower die), so that the machining accuracy is reduced. Therefore, it has been difficult to use the C-type frame press for high precision processing. Further, not only the C-type frame press but also a relatively inexpensive press machine in which the direction of the vertical movement of the ram with respect to the bolster changes, has the same problem.

SUMMARY OF THE INVENTION A die set device of the present invention includes a lower die support fixed to a bolster side; a lower die support supported on the lower die support via a guide mechanism, and a lower die via a ram. In a die set device provided with an upper die support that receives a moving force to the support side, one of a convex spherical washer and a concave spherical washer, which come into contact with a part of a spherical surface, is attached to the upper end of the upper die support. It is characterized in that it is fixed and the other of the convex spherical washer and the concave spherical washer is brought into contact with the ram side member fixed to the ram. The convex spherical washer or the concave spherical washer that contacts the ram side member is preferably slidable with respect to the ram member in a direction orthogonal to the up-and-down direction of the ram. According to this die set device, even if the change in the vertical movement of the ram slightly changes, the spherical washer absorbs the change in the direction and maintains the linear movement of the upper die support with respect to the lower die support.
Therefore, highly accurate processing can be performed.

A spherical washer unit 30 is provided at the upper end of the upper die support 26. This spherical washer unit 3
As shown in FIG. 3, 0 is a concave spherical washer 31 having a part 31 s of the concave spherical surface, and a concave spherical washer 31 s of the concave spherical washer 31.
Convex washer 32 having a part of a convex spherical surface 32s engaging with
And the concave spherical washer 31 is fixed to the upper die support 26. On the other hand, the convex spherical washer 32 has the ram 1 at its upper surface.
It simply contacts the lower surface of the ram side member 33 fixed to the ram 5, and is slidable in a direction orthogonal to the vertical direction of the ram 15. The concave spherical washer 31 and the convex spherical washer 32 are
It is possible to freely rotate along the contact surface between the spherical surfaces 31s and 32s, so that the upper die support 26 can rotate with respect to the ram side member 33. In order to ensure the free movement of the upper die support base 26 with respect to the ram side member 33, the upper die support base 26 and the ram side member 33 are not in contact with each other. A suspension rod 36 that is loosely fitted in a play hole 35 formed in the ram side member 33 is provided on the upper die support 26. A spring receiver 37 fixed to the upper end of the suspension rod 36 and a ram side. Member 3
The contact state between the concave spherical washer 31 and the convex spherical washer 32 is maintained by the compression coil spring 38 inserted between the concave spherical washer 31 and the convex spherical washer 32. The spring receiver 37 and the compression coil spring 38 are unitized mainly so that the concave spherical washer 31 and the convex spherical washer 32 are not separated when the die set device 20 is moved out of the space between the bolster 14 and the ram 15. To act. The concave spherical washer 31 is replaced by an air cylinder device or a hydraulic cylinder device instead of the spring receiver 37 and the compression spring 38.
It is also possible to form a unit so that the convex spherical washer 32 and the convex spherical washer 32 are not separated from each other.

The die set device 20 having the above structure is inserted between the bolster 14 and the ram 15, the lower die support 21 is fixed to the bolster 14, and the ram side member 33 is fixed to the ram 15. The lower die fixing surface 22 of the lower die supporting base 21 and the upper die supporting surface 25 of the upper die supporting base 26 respectively support the lower die and the upper die for press working. When the ram 15 is reciprocally moved with respect to the bolster 14 and press-worked after the above-mentioned setting is completed, the descending force of the ram 15 is transmitted to the concave spherical washer 31 via the convex spherical washer 32, and the upper die supporting base is supported. 26 descends. At this time, if the direction of the vertical movement of the ram 15 changes as a result of the upper arm 12 and the lower arm 13 of the C-shaped frame 11 opening slightly, the concave spherical washer 31 and the convex spherical washer 3
The spherical engagement of 2 changes the contact position according to the change of the direction, and transmits only the force perpendicular to the bolster 14 to the upper die support 26. At this time, the ram side member 33
The concave spherical washer 32 slides with respect to the ram side member 33 when a force greater than a certain value in the sliding direction is applied between the convex spherical washer 32 and the convex spherical washer 32. For this reason, the upper die support 21 performs a correct vertical movement along the guide posts 23 and the guide rails 24 even when the upper arm 12 and the lower arm 13 of the C-shaped frame 11 are slightly opened. For this reason, even if there is a slight change in the ascending / descending direction of the ram 15, the die set device 20 can perform highly accurate press working.

Although a certain effect can be expected even if the convex spherical washer 32 is fixed to the ram side member 33, if it is slidable as in the illustrated embodiment, the force in the direction orthogonal to the vertical direction of the ram 15 is generated. The upper die support 26 is rarely affected.
