Problems solved by technology

[0003] We have conducted research on domestic bridges, containers, ships, automobiles and other large-scale enterprises that use steel plates, and found that using three methods of flame, plasma, and roller shears to separate steel plates longitudinally and linearly has many processing defects that are difficult to correct by themselves. The process and structure process bring the disadvantages of the same type, bury hidden dangers for the processed products, and seriously affect the reliability and stability of the products

[0004] The disadvantages of cutting steel plates with flame cutting machines are that the preheating and perforation time required for cutting is long, the cutting speed is slow, the thermal deformation during cutting is large, and the burning of fuel causes serious environmental pollution.

There is an oxide layer left in the double-sided incision, which needs to be ground off during welding, especially the steel plate after thermal deformation is difficult to correct, and some products are used in equipment with different deformed workpieces, which seriously affects the internal quality of the product

[0005] Plasma cutting cannot cut thick plates, and its cutting precision is high, but the use cost is also high, so it is not suitable for large-volume and high-efficiency production links

[0006] The steel plate is cut by roller shearing, the steel plate is in the form of pressure tearing, the workpiece has a double-sided camber, and the metallographic structure within 10-15mm undergoes fusion. To meet the strict technical requirements of the mechanical structure or welding structure, it is necessary to cut off 10-10mm on both sides of the steel plate. 15mm edge material, resulting in huge waste of material, increasing the processing cost of straightening on both sides
