Stamping die

Abstract

The invention discloses a stamping die which comprises an upper die, a lower die and a supporting seat, wherein the upper die comprises an upper punch-die; the lower die comprises a lower punch-die; the upper punch-die is matched with the lower punch-die; the lower die is arranged on the supporting seat; the lower die further comprises a guide device; and the guide device is arranged at the upper end face of the lower punch-die and provided with a guide part which is matched with the upper punch-die so as to enable the upper punch-die to slide in the guide part. The stamping die provided by the invention comprises the upper die, the lower die and the supporting seat, wherein the lower die is provided with the guide device; and the guide part of the guide device is matched with the upper punch-die of the upper die. Since the guide device is simple in structure, compared with the prior art, the stamping die has the advantages that a guide post structure and a guide sleeve structure are omitted, the overall structure of the stamping die is simplified, the difficulty of the processing process is reduced, and the production cost is lowered.

Description

technical field [0001] The invention relates to sheet material processing technology, in particular to a stamping die. Background technique [0002] Stamping dies are dies used for sheet metal stamping and blanking separation, including punching dies, bending dies, deep drawing dies, and hole turning dies. In the stamping die, the sheet is formed through the mold cavity, and the sheet is separated or cut through the punching edge of the stamping die. The most commonly used stamping die has only one station to complete a production process. In order to improve productivity, multiple stamping processes, such as blanking, deep drawing, punching, trimming and other processes, can be designed on one stamping die, so that the sheet can complete multiple stamping processes at one station. The mold is called a compound mold. [0003] Stamping dies usually include upper die, lower die, upper die fixing plate, lower die fixing plate, guiding device, positioning device and unloading...

AI Technical Summary

Problems solved by technology

[0004] During the research process of the present invention, the inventor found that the stamping dies of the above-mentioned prior art have the following technical defects: the existing stamping dies usually have independent guiding devices and unloading devices, thus resulting in complex structures of the stamping dies and difficult processing.
