Description

Technical Field

[0001] The utility model relates to the technical field of punching assistance, in particular to a plate feeding auxiliary positioning device for a punching die. Background Art

[0002] The plate feeding auxiliary positioning device for stamping dies is a device used to help the stamping die to accurately position the plate during the stamping process. It is usually composed of a base fixed on the die and a movable plate feeding device. During the stamping process, the plate feeding device moves with the opening and closing of the die, thereby achieving the positioning and stamping of the stamped parts.

[0003] In the prior art, the feeding plates are usually clamped in the slide grooves on both sides of the mold. However, after each stamping, the plate will produce a slight shrinkage deformation due to the stamping of the concave and convex mold, which reduces the tightness of the clamping with the slide groove, and is easy to deviate when continuing to move, resulting in a decrease in stamping accuracy, thereby affecting production efficiency. In addition, the slide grooves used to clamp the feeding plates are all of fixed depth. The plate can be clamped just right at the beginning, but after the mold is pressed, the plate will usually shrink slightly, resulting in the slide groove and the plate not fitting together. At present, there is basically a lack of devices that can fine-tune the depth of the slide groove, resulting in poor auxiliary positioning effect for the feeding plate in actual use. At the same time, the precise fitting is too rigid during use, and the stamping effect will be affected. Utility Model Content
