An electric winding roller 308 is installed at the bottom, and the electric winding roller 308 is fixedly connected to the lower end of the wire rope 307. The limit bracket 404 is connected to the cutter assembly 4 by a fixing screw, and spring winding rollers 406 are installed at both ends of the limit bracket 404. One end of the spring winding roller 406 is fixedly connected to the upper end of the wire rope 307. The spring damper 304 and the wire rope 307 are used for limiting, so that the shearing process is set to be nonlinear, so that the overall force effect of the channel steel 2 to be sheared and the shearing machine loading rack 1 is uniform, which meets the actual working intensity, so as to carry out long-term work, improve the stability of the device, and improve the processing effect.

[0022] A connecting ear 305 is installed at the upper end of the fixing frame 303, and the lower end of the spring damper 304 is movably connected to the fixing frame 303 through the connecting ear 305. A bearing sleeve 306 is installed between the spring damper 304 and the cutter assembly 4. The spring damper 304 is movably connected to the cutter assembly 4 through the bearing sleeve 306. During the downward pressing work, the cutter assembly 4 is limited by the spring damper 304, which improves the position stability and is conducive to long-term work.

[0023] Specifically, after the support frame 3 is installed on the shearing machine feeding frame 1 and the channel steel 2 to be sheared is fixed, the shearing work is carried out. During the shearing process, the cutter assembly 4 is limited by the spring damper 304 and the wire rope 307 during its movement, so that the shearing process is set to be nonlinear, so that the overall force effect of the channel steel 2 to be sheared and the shearing machine feeding frame 1 is uniform and meets the actual working intensity, so as to carry out long-term work, improve the stability of the device, and improve the processing effect.

[0024] In order to solve the problem that the shearing machine has poor position stability during the actual use of the existing technology, which affects the processing, please refer to Figure 1 , Figure 4 , this embodiment provides the following technical solutions:

[0025] A movable slide 101 is installed in the middle of the shearing machine loading rack 1.

Positioning slide rods 102 are installed on both sides below the shearing machine loading rack 1. During operation, the length of the shearing machine loading rack 1 is adjusted by adjusting the movable slide 101 and the positioning slide rod 102, so that the position of the spring damper 304 and the cutting knife assembly 4 can be adjusted, and adjustments can be made according to the shearing position to adapt to different processing intensities.

[0026] First hydraulic cylinders 302 are installed on both sides of the support frame 3, and the first hydraulic cylinders 302 are fixedly connected to the support frame 3 and the shearing machine feeding frame 1 respectively. The lifting and pressing plates 301 are driven to move by the first hydraulic cylinders 302, and the support frame 3 is installed on the shearing machine feeding frame 1. The lifting and pressing plates 301 are driven downward by the first hydraulic cylinders 302 to fix the channel steel 2 to be sheared. After the fixing is completed, the cutter assembly 4 is driven to rise and fall by the second hydraulic cylinder 403 to perform shearing. Connecting rods 401 are installed on both sides of the cutter assembly 4, and a lifting frame 402 is installed on one side of the connecting rod 401.

The lower end of the cutter assembly 4 is provided with an integrally formed cutting head 405.

[0027] Specifically, when in use, the length of the shearing machine loading rack 1 is adjusted by adjusting the movable slide plate 101 and the positioning slide rod 102, so that the positions of the spring damper 304 and the cutting knife assembly 4 are adjusted, and adjustments are made according to the shearing position to adapt to different processing intensities. The support frame 3 is installed on the shearing machine loading rack 1, and the lifting and pressing plate 301 is pressed down by the first hydraulic cylinder 302 to fix the channel steel 2 to be sheared. After the fixing is completed, the cutting knife assembly 4 is driven to rise and fall by the second hydraulic cylinder 403 to perform the shearing work.

[0028] Working principle: before work, the length of the shearing machine feeder 1 is adjusted by adjusting the movable slide plate 101 and the positioning slide rod 102, so that the positions of the spring damper 304 and the cutting knife assembly 4 are adjusted, and adjustments are made according to the shearing position to adapt to different processing intensities. During work, the support frame 3 is installed on the shearing machine feeder 1, and the lifting and pressing plate 301 is pressed down by the first hydraulic cylinder 302 to fix the channel steel 2 to be sheared. After the fixing is completed, the cutting knife assembly 4 is driven to rise and fall by the second hydraulic cylinder 403 to perform shearing work. The support frame 3 is installed on the shearing machine feeder 1. After the channel steel 2 to be sheared is fixed, the shearing work is performed.
