Stamping die capable of keeping pressing leftover material parts of plates

Abstract

The invention provides a stamping die capable of keeping pressing leftover material parts of plates. The stamping die comprises an upper die seat and a lower die seat. A convex die is arranged at thelower end of the upper die seat, and a concave die is arranged at the upper end of the lower die seat. Multiple pressing devices are evenly distributed on the upper die seat with the convex die as thecenter. Each pressing device comprises a base, a press plate below the base and multiple pressing mechanisms between the base and the press plate. A press pad is arranged on the lower end face of each press plate. A concave cavity is arranged at the lower end of the upper die seat, and a base body of the convex die is mounted in the concave cavity and is fixed by a locating pin mounted on the upper die seat. The structural design of the stamping die is reasonable; and through the arranged pressing devices, in the stamping process, the leftover material parts of the plates are kept being pressed, leftover materials are prevented from rebounding, and the effect is remarkable. The convex die is fixed to the upper die seat through the locating pin, demounting and replacement can be facilitated, universality is good, the locating pin only achieves a locating function and does not achieve the function of mainly bearing stamping loads, the structure stability is good, and the service life islong.

Description

technical field [0001] The invention belongs to the technical field of stamping equipment, and in particular relates to a stamping die capable of keeping the leftover parts of a plate pressed. Background technique [0002] The application fields of sheet metal parts are extremely wide, and they penetrate into all aspects of the manufacturing industry. Sheet metal forming is mainly realized by stamping dies. Using the stamping process, it has a series of advantages such as high precision, high efficiency, good quality, cost saving, material and energy saving. However, when the existing stamping equipment stamps the workpiece, it is easy to cause the punched off scraps to be picked up by the punch, or to be splashed by the impact force during the stamping process, which does not affect the processing accuracy, and even easily causes personal injury. Injuries are in dire need of improvement. Contents of the invention [0003] The problem to be solved by the present inventio...
