The material is formed into a tube of good quality by a forming machine, which is then welded into a circular tube by a welding machine. The quality of the forming process directly affects the welding quality. Under certain equipment conditions, taking appropriate adjustment measures is the basis for good forming of the pipe forming equipment.
The material passes through the forming machine to form a tube of good quality, which is then welded into a circular tube by a welding machine. The quality of the forming process directly affects the welding quality. Under certain equipment conditions, taking appropriate adjustment measures is Square Tube Machine the basis for good forming equipment.
1. Basic requirements for forming quality include:
A. The formed tube blank has the correct circular tube shape;
B. The tube dimensions meet the needs of the die design;
C. The edges of the weld seam are straight and there is no high and low welding;
D. There is no twisting phenomenon in the weld seam;
E. There is no wave or bulge phenomenon on both edges of the weld seam of the square tube machine;
F. Adjust the opening angle to the required degree (2～6 degrees)
G. The tube blank has no roll pressure marks or serious scratches and other surface defects.
2. Adjustment and maintenance of the forming machine
① Flat roll adjustment
A. Pressure adjustment: By rotating the nut of the pressure down screw on the bearing seat, the pressure down screw is raised and lowered, driving the bearing to rise and fall. The two bearing seats are adjusted independently.
B. Axial adjustment
3. A positioning surface is left at one end of the lower bearing to position the lower roll. A set of nuts is installed at both ends of the upper roll shaft. By rotating the nuts, the upper roll is moved to achieve axial adjustment.
