Bending-angle-adjustable hardware punching die structure

Abstract

The invention discloses a bending-angle-adjustable hardware punching die structure. The bending-angle-adjustable hardware punching die structure comprises an upper die base and a lower die base. The lower end of the upper die base is fixedly provided with a mounting base, the lower end of the mounting base is provided with an upper die in a matched manner, the lower end of the mounting base is provided with dovetail grooves, two sides of the upper end of the upper die are fixedly provided with dovetail-shaped sliding blocks, and the sliding blocks of the upper die are mounted in the dovetail grooves of the mounting base in a matched manner. The upper die is of a C-shaped structure, the front end of a lower arm of the upper die is provided with an adjusting plate, the tip of the front end of the lower arm of the upper die is provided with a through hole, and the lower end of the adjusting plate is fixedly provided with a rotating shaft. By means of the bending-angle-adjustable hardwarepunching die structure, the bending angle of an abrasive tool can be adjusted in a stepless manner, and the adjustment manner is simple and quick, beneficial to reducing the experiment expense and accelerating the experiment progress.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a metal stamping die structure with adjustable bending angles. Background technique [0002] Stamping machine tools are commonly used mechanical equipment in the field of metal processing. Stamping machine tools are stamping equipment that use molds to stamp stamping materials. Commonly used stamping equipment is divided into two categories: mechanical presses and hydraulic presses. Generally, mechanical presses are used. The type of stamping equipment is selected according to the nature of the stamping process, production batch, size and precision of stamping parts, etc. For small and medium-sized blanking parts, bending parts or deep-drawing parts, open mechanical presses are mainly used; for large and medium-sized stamping parts, closed mechanical presses are mostly used; for stamping parts produced in small batches, hydraulic presses or friction presses are mostly use...

AI Technical Summary

Problems solved by technology

[0003] During product development, some product raw materials have great resilience. When these raw materials are used for production, the bending cannot meet the product requirements due to the resilience of the material during bending.

In order to solve the springback problem, a negative angle is required when bending. Because the springback angle cannot be calculated, it is necessary to conduct a large number of bending experiments on raw materials to collect experimental data. Each bending angle requires a mold with a corresponding angle. This increases the cost of the experiment, and the mold production cycle is longer, which seriously affects the collection of experimental data
