Description

Technical Field

[0001] The invention relates to the technical field of rubber production and cutting, in particular to a cutting device for wear-resistant rubber. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a molecular weight that is often large, greater than hundreds of thousands. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from plants such as rubber trees and rubber grass; synthetic rubber is obtained by polymerization of various monomers.

[0003] A support device for cutting a rubber hose with the announcement number CN216442635U relates to the technical field of rubber hoses, and includes a working platform, a top frame is provided above the working platform, support rods are fixedly connected at the corners of the bottom surface of the top frame, the upper end of each support rod is fixedly connected to the bottom surface of the top frame, an electric push rod is fixedly connected to the bottom surface of the top frame, a motor 1 is fixedly connected to the bottom end of the electric push rod, and a cutting blade is installed on the output shaft of the motor 1. The patent has a reasonable design structure, and it can drive the lifting slide rod, the cross frame and the extrusion plate to descend through the coordinated design of the working platform, the support rod, the top frame, the electric push rod, the motor 1, the cutting blade, the lifting mechanism, the clamping mechanism and the slide groove, and the cross bar is lowered to drive the lifting slide bar, the cross frame and the extrusion plate to descend, and the hose is fixed in the vertical direction by the extrusion plate, so as to achieve a good fixing effect on the hose. When cutting the hose, the incision of the hose will not be uneven, and the cutting quality of the hose will not be affected.

However, since the hose itself is made of soft material, the clamping force of the clamping blocks is large and will cause it to deform, which will affect the cutting accuracy. Moreover, since the hose needs to be docked, its incision is not entirely a disposal cut. Some rubber hoses need to be cut at an angle. The cutting method of the device is single and cannot meet most needs. Therefore, the above device needs to be improved. Summary of the invention
