A key process. Traditional disc shears are divided into single-blade disc shears and double-blade disc shears. Single-blade disc shears have a simple structure and relatively small investment, but the production rhythm is insufficient, so they are generally only used in discontinuous units; and The double-blade disc shears are relatively complicated in structure and relatively large in investment, but they can meet the conditions of high production rhythm, so the continuous unit adopts double-blade disc shears.

The traditional double-head disc shears design adopts a structure in which the disc shears are equipped with two knife seats on the transmission side and the operation side respectively, and each knife seat is equipped with a set of knife heads; at the same time, in order to meet the needs of changing the cutting blade According to the needs, the two tool holders are arranged on a rotary table, and the steering is realized through the rotary bearing. Therefore, the structure is complicated and the investment cost is high. In particular, in the process of replacing the cutting blade, it is necessary to move the knife seat to the limit position of the support through the width adjustment device, then drive the slewing support to rotate 180°, and finally move the knife seat to the cutting position, which is a complicated process , and it takes a lot of time, which seriously affects the production rhythm of the unit. Therefore, it is very necessary to develop a brand-new disc shear, which can maintain the advantages of simple structure and low investment of single-blade disc shears, while satisfying the function of double-blade disc shears that can replace the cutting blades outside the line, and can improve The efficiency of replacing the cutting blade can improve the production rhythm of the unit.

Therefore, it is very necessary to develop a brand-new disc shear, which can maintain the advantages of simple structure and low investment of single-blade disc shears, while satisfying the function of double-blade disc shears that can replace the cutting blades outside the line, and can improve The efficiency of replacing the cutting blade can improve the production rhythm of the unit.
