[0002] Stamping dies are special tools used for metal processing and are widely used in manufacturing industries such as automobile manufacturing, home appliance manufacturing, and electronic equipment manufacturing. Stamping processing is achieved by placing metal sheets in a die and then applying pressure to cause the sheets to undergo plastic deformation or separation to obtain the desired shape and size.

[0003] When the stamping die is in use, in order to avoid the workpiece from deviating during the stamping process, the two sides of the workpiece will be positioned. However, during positioning, it is necessary to manually operate the clamping mechanism to move and clamp the workpiece, which is more troublesome. Moreover, after the stamping is completed, the workpiece cannot be conveniently removed because it is positioned. Utility Model Content

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the present invention, the workpiece is placed between the two limit plates by arranging the lower die seat, the limit rod, the limit plate and the support block to cooperate with each other. The two limit plates automatically perform preliminary clamping and positioning on the workpiece under the push of the clamping spring. At this time, the workpiece is in a state of being held up by the support block. Then the upper die seat descends under the control of the lifting device. When the pressure rod of the upper die seat contacts the workpiece, as the upper die seat continues to descend, the pressure rod will press the workpiece downward. At this time, the support block will compress the push spring. When the pressure rod drops to a certain height , the limit rod on the upper die seat will first be inserted into the limit hole of the limit plate and contact with the lower die seat, so that the limit plate can be positioned. At this time, the pressure rod continues to descend. During the process of the pressure rod continuing to descend, the limit rod will be pushed up by the lower die seat until the pressure rod presses the workpiece on the lower die seat and completes the processing. Finally, the upper die seat rises, and the support block will lift the workpiece up under the pushing action of the push spring. Since the limit rod has been pulled out of the limit hole at this time, the staff can easily remove the workpiece from between the two limit plates. BRIEF DESCRIPTION OF THE DRAWINGS
