,Use hydraulic rolling shear cut, cut flat without burr. The cutting process is non-sparking, noise is low, and it is safer. 2,The fixed mold is used to make the tube size more accurate and uniform, and it is more convenient, stable, rapid and flexible to change the die with different dimensions and adjust the spiral angle. 3,The hydraulic system is adopted to complete the operation of material conveying, cutting, cutting, turning, and the like, and the degree of automation is high. The strip material can flexibly adjust the pressure of the material according to different materials, the thickness and the pipe diameter, and ensure the quality. 4,The two-way throttle speed-regulating valve is adopted, so that the adjustment of each moving part is more convenient.
