Description

Stainless steel strip cutting structure Technical Field The utility model relates to the technical field of stainless steel strip cutting, in particular to a stainless steel strip cutting structure. Background The stainless steel strip is steel which takes stainless and corrosion resistance as main characteristics, has a chromium content of at least 10.5 percent and a carbon content of maximally not more than 1.2 percent. It is a metastable austenitic stainless steel having a complete austenitic structure, and its strength and hardness can be remarkably improved by cold deformation processing while retaining sufficient plasticity and toughness. In the conventional cutting process of the stainless steel strip, uneven stress distribution can be formed by the operation mode of unidirectional rotation of the cutting wheel. When the cutting edge cuts into the material in a single direction, the steel strip section is subjected to asymmetric shear forces, which can easily lead to microcracks or burrs at the cut. Because the stainless steel material has higher toughness and work hardening property, heat generated by unidirectional cutting can be concentrated in a local area, and the change of the metallographic structure of the material can be possibly caused. The cutting mode can also cause the waveform deformation of the edge of the steel belt, and the accuracy of the subsequent processing procedures such as bending, welding and the like is affected. In the operation process, vibration generated in the moment that the cutting wheel is in contact with the steel belt can be transmitted to the whole roll of material through equipment, so that transverse swing of the steel belt is enhanced. This process is particularly true for thin gauge precision stainless steel strips, which often require additional shaping steps to correct the deformation. The Chinese patent discloses a steel belt cutting device (grant bulletin No. CN 201455414U), which mainly comprises a frame body, wherein a conveying part and a cutting part are arranged on the frame body, the cutting part comprises a cutter head and a cylinder connected with the cutter head, the cutting part also comprises a control part, the conveying part comprises a fixed clamp, a movable clamp and a movable clamp cylinder, the movable clamp is in transmission connection with the movable clamp cylinder, the movable clamp cylinder is provided with a stroke control structure, and the control part is respectively and electrically connected with the cylinder connected with the cutter head and the movable clamp cylinder. However, the stainless steel strip is cut by a cutting device, but when the cutting wheel on the cutting device cuts, the cutting efficiency is low, and the cutting force is unbalanced easily, so that the stainless steel strip is deformed. Accordingly, a person skilled in the art provides a stainless steel strip cutting structure to solve the problems set forth in the background art.
