Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die with a replaceable stamping die head. Background Art

[0002] A stamping die is a process equipment used for stamping processing. It achieves plastic deformation or separation of the material by applying pressure to the material at room temperature, thereby manufacturing the required parts or semi-finished products.

[0003] After searching, it was found that the Chinese patent announcement number CN217223249U discloses a stamping die for stamping. The device retracts into a movable groove 1 under the action of the die gravity and the sliding component through the universal wheel to fix the lower die, making the installation of the die faster and more convenient. Since the stamping die requires the upper die to stamp the lower die, and frequent operations can easily damage the upper die, the upper die needs to be replaced at this time, but the upper die head of the device is fixedly installed at the bottom of the upper die, and the upper die is installed and connected using a spring and a mounting bracket. When replacing, the spring, the upper die body and other parts need to be replaced as a whole. The operation is relatively cumbersome, and the material loss is large, so the existing device needs to be improved to meet actual needs. Utility Model Content
