Bending and shaping structure for slide block of continuous punching die

Abstract

The invention discloses a bending and shaping structure for a slide block of a continuous punching die. The structure comprises a lower die holder, a lower die plate, a first nitrogen spring, a secondnitrogen spring, a first slide block, a second slide block, a third slide block, a fourth slide block and a shaping block. The lower die plate is arranged at the upper end of the lower die holder, the shaping block is arranged on the lower die plate, the first and second slide blocks are arranged on one side of the shaping block, the third and fourth slide blocks are arranged on the other side ofthe shaping block, the first and second slide blocks are matched with the first nitrogen spring mounted on one side, the third and fourth slide blocks are matched with the second nitrogen spring mounted on one side, first inserted blocks are arranged at the lower ends of the first and second slide blocks, and second inserted blocks are arranged at the lower ends of the third and fourth slide blocks.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a bending and shaping structure of a continuous stamping die slider. Background technique [0002] With the continuous improvement of the quality of industrial products and the increasing complexity of workpieces, the production of mold products presents multiple varieties, small batches, complex, and large-scale precision replacements are developing rapidly. The high precision, high complexity, high productivity, high consistency and consumption of mold production parts cannot be fully displayed in other manufacturing and processing aspects, so it has good economic benefits. [0003] In the stamping process of metal processing parts, bending is a common process. Different workpieces have different requirements for the bending angle. When the workpiece needs to be bent at an angle of 90 degrees, the quality of the bending cannot be guaranteed during the bending process thro...

Problems solved by technology

[0003] In the stamping process of metal processing parts, bending is a common process. Different workpieces have different requirements for the bending angle. When the workpiece needs to be bent at an angle of 90 degrees, the quality of the bending cannot be guaranteed during the bending process through the mold. , causing the workpiece to fail to meet the process requirements and be scrapped, and at the same time cause damage to the mold itself

At the same time, a slight deviation in the bending positioning of the workpiece end will cause the appearance to be scrapped

Moreover, due to the high hardness of some plates, the rebound after bending is also large, and the product size is difficult to control within the tolerance range. Therefore, it is necessary to increase the secondary shaping process, which wastes manpower and material resources.
