[0002] The circular shear uses two circular shears for shearing. It is an instrument that shears according to the different relative positions of the axes of the two scissors and the different angles between the axes and the sheet material. It is divided into straight rolling shears, return disc shears and oblique rolling shears. For this type of circular shear, it is usually mainly used for finishing of thick plates and other steel materials.

[0003] According to a disclosed disc shearing machine (publication number: CN 208513761 U), a disc shearing machine includes a frame, a driving mechanism fixed on the frame, and two mounting plates. The first rotating shaft and the second rotating shaft are synchronously connected by a belt. A fixed shaft is arranged between the two mounting plates, and a plurality of horizontally arranged pressure plates are sleeved on the fixed shaft. A transmission platform is arranged on both sides of the frame. The transmission roller is driven by the driving mechanism. The transmission platform is located on both sides of the lower cutting disk. The transmission belt is tilted downward for transmission. The above mechanism drives the first rotating shaft and the second rotating shaft through a driving motor to cut the plate. This cutting method can only produce one finished product at a time, and can only cut one size, so the cutting efficiency is low. Utility Model Content

[0025] In this way, the plate to be cut is placed on the conveyor belt 402 and transported to the cutting mechanism 1 by the conveyor belt 402. The plate is cut by the first shearing wheel 103 and the second shearing wheel 102. When the cutting size needs to be changed, the drive motor 101 is started to change the position of the cutting mechanism 1, thereby changing the cutting size. Two cutting mechanisms 1 are fixed on the frame 5, and the plates can be cut at the same time. By adjusting the position of the cutting mechanism 1 to different positions, two sizes of plates can be cut at one time, thereby reducing working hours and improving work efficiency.

[0026] As an optional implementation, Figure 3 As shown, the clamping mechanism 2 includes an upper clamping block 201 and a lower clamping block 204, the upper clamping block 201 is slidably connected to the upper fixed frame 106, a number of first springs 202 are evenly fixedly connected between the upper fixed frame 106 and the upper clamping block 201, a number of clamping wheels 203 are evenly fixedly connected to the end of the upper clamping block 201 away from the first spring 202, the lower clamping block 204 is slidably connected to the lower fixed frame 108, a number of second springs 205 are evenly fixedly connected between the lower fixed frame 108 and the lower clamping block 204, and a number of clamping wheels 203 are evenly fixedly installed on the end of the lower clamping block 204 away from the second spring 205.

Under the action of the first spring 202 and the second spring 205 on the upper fixing frame 106 and the lower fixing frame 108, the clamping wheel 203 is always kept in a clamping state, so that the first shearing wheel 103 and the second shearing wheel 102 cut the plate without warping, so that the cutting size is more accurate. When the cutting size needs to be changed, the driving motor 101 is started to change the position of the cutting mechanism 1, and then the cutting size is changed.
