SU94835A1 - Adaptation to a punching press for raising and lowering a crimp ring with a part stamped on a piercing table - Google Patents

Description

The existing tools for punching to lift and lower the crimp ring with the part to be stamped on the table are complex in their design, since they consist of separate manipulator mechanisms, which significantly reduces the operational qualities of the installation.

The proposed device differs from the known ones in order to lift and lower the crimp ring with the part without using separate handling devices and to speed up the lifting and lowering of the crimp ring, it is made in the form of several spring-mounted lever hooks with protrusions and corresponding im the number of levers.

The drawing shows part of a vertical punching press with a device.

The fixture is intended for lifting and lowering a compression ring in which a disk-shaped part is pressed.

The device consists of several lever grippers 2 and levers 3, of which the first are mounted directly on the upper die 4, and the second on the piercing table 5.

To ensure interaction between the lever arms 2 and the arms 3, they are spaced evenly around the compression ring I, one above the other in a vertical position.

Lever clamps 2 upper part freely suspended on horizontal axis x 6, mounted in the brackets 7, which are rigidly fixed on the top of the stamp 4. The lower ends of the lever grippers provide bevel n reverse projections, made in the form

hooks. In order to ensure reliable operation of the lever grippers 2, the upper part of them is loaded with a flat spring 8.

The upper ends of the two-shoulder arms 3 have bevels, and the lower ones are equipped with weights 9. The levers 3 have a middle part freely suspended on horizontal axes x 10 to the brackets I, which are rigidly attached to the “piercing table 5.

When the press operates, the lever grippers 2, with their bevels, interact with the bevels of the levers 3, thus achieving the possibility of raising and lowering the crimping ring with the part being stamped into it.

When lowering the press yoke, the lever arms 2 slide along the lateral outer surface of the compression ring 1 lying on the table, are moved apart, and the action of the spring 8 moves beyond the shoulder of the ring 1, and the upper arms of the levers 3 turn towards the center of the table. When lifting the yoke, the lever grippers 2 capture the crimp ring 1 and lift it off the table.

When the traverse is re-lowered with a compression ring 1 on the piercing table 5, the lever clamps 2, interacting with the levers 3, are again moved apart and, releasing the clamping ring shoulders, leave it on the piercing table 5. Then the work of the tool is repeated.
