a cutting die

Abstract

The invention discloses a shearing die which comprises a die body and a cutting board base. A loading channel which is used for loading a material and adapts to a material structure is horizontally arranged on the right side of the die body, the cutting board base is vertically inserted into the die body and penetrates out of the middle of the loading channel. The upper portion and the lower portion of the cutting board base are respectively provided with a first channel and a second channel which adapt to the loading channel structure, and the positions of wall edges of two sides of the second channel are sharp and abut against the wall of the die body. A pressure application device is arranged above the cutting board base. The material is inserted into the loading channel from the side right of the die body, penetrates the second channel and then abuts against the bottom of the channel, and at the time, the length of the material located in the second channel is consistent with the length of the material located on the left side of the second channel. After the material is loaded well in the loading channel, the pressure application device works to drive the loading channel to move downwards, and the two ends of the material located in the second channel are sheared and two sections of materials with a predetermined length are obtained. Compared with a conventional cutting machine, the shearing die greatly improves shearing efficiency.

Description

technical field [0001] The invention relates to a cutting device, in particular to a shearing die. Background technique [0002] Cutting is a commonly used processing method in the industrial field. The commonly used cutting method is realized by sawing machines, which are divided into circular sawing machines, band sawing machines, and bow sawing machines. The circular sawing machine is a circular saw blade that performs a rotating cutting motion, and at the same time performs a feed motion with the saw knife box. The band saw machine is a circular saw band tensioned on two saw wheels, and the saw wheels drive the saw band to cut. The bow sawing machine is a saw bow equipped with a saw blade that reciprocates, and is fed by swinging the saw frame around a point. The machine tool has a simple structure and a small size, but its efficiency is low. There are two types of motion trajectory of bow saw blade: straight line and arc. When the arc moves, the saw bow swings around...

AI Technical Summary

Problems solved by technology

[0003] However, whether it is a circular saw machine, a band saw machine or a bow saw machine, there are cutting debris in the cutting process, so there is a material loss, which is about 4% to 6%, resulting in an increase in production costs.

In addition, the current cutting of materials is to obtain a workpiece with a suitable length at one time, and the work efficiency of cutting workpieces in a large number of materials is not high
