When the used ERW tube mills is used to make welded pipes, the judgement of the qualified quality of the welded pipe depends on the control of the squeeze roller, so the control of the squeeze roller is very important. There are many ways to control the squeeze roll, and "up and down two" is one of the squeeze roll methods.

 

Used ERW tube mills

 

Although the "up one down two" three-roller extrusion method has the characteristics of independent adjustment, three-roller unified adjustment, overall rotation and easy adjustment of the It covers 120 degrees, and the diameter and load capacity of each roller is effectively reduced, which avoids many of the disadvantages of the two-roller and the top three-roller. However, it is still impossible to avoid the existence of the independent top-roller three-roll squeeze mode. Shortcomings. Because of the small roll diameter of the used ERW tube mills, its bypass current is much smaller than that of the "two on one side" top roll extrusion device. However, equipment manufacturing also has the problems of relatively high technical requirements, processing accuracy requirements and relatively high cost, and relatively difficult adjustments. Only a few manufacturers currently use it.

 

The above is the method of adjusting the squeeze roll of the used ERW tube mills "up one down two", the next issue will introduce the method ④ "two top rolls and two side vertical rolls". If you need it, you can pay attention to the method in the next issue. At the same time, if you need used welded pipe equipments, please contact us. You only need to inform us of your pipe-making needs, and our company will provide you with used welded pipe equipments that really suits your needs.

Why does the used roll forming machine flying saw saw lack of lubrication?
When the used roll forming machine produces steel pipes, the pipe fittings move at a constant speed according to the set speed, and the saw car is stationary relative to the unit before the sawing process. When the steel pipe reaches the set length, the clamping device of the saw car clamps the steel pipe, and the drive mechanism drives the saw car to move with the steel pipe and perform the sawing process until the sawing operation is completed. When the sawing process of the flying saw is completed, the driving device drives the saw carriage to return to the initial position. The reciprocating motion of the saw car is realized by the relative movement of the rack at the bottom of the saw car and the gear fixedly installed on the machine bed system.

Weld quality failure caused by used welded pipe machines (9)
When manufacturing welded pipes for used welded pipe machines, judging that the quality of the welded pipes meets the standard depends on the quality of the welds. Therefore, the quality of the weld is very important, so sometimes it is necessary to rule out the quality of the weld. We perform analyses to understand weld quality failures.
