High frequency welded pipe equipment to produce welded pipe forming technology is developed in three stages according to time period and forming method: Roll Forming,Caga Forming, and Flexible Forming Excellent.

 

High frequency welded pipe equipment

 

High frequency welded pipe equipment welded pipe forming technology includes two parts: rough forming and fine forming. It is the core of high-frequency welded pipe production technology. If the forming quality of the steel strip in the rough forming and finishing stages is not good or the forming is not in place, it is difficult to produce Produce high-quality welded pipes. Therefore, the forming technology determines the output, variety, quality, raw material and roll consumption of the high-frequency welded pipe, which is a matter of great concern to the design and manufacturing department and the user department of the welded pipe equipment.

 

High frequency welded pipe equipment

 

Let's start to talk about the characteristics of these three molding technologies.

1. Roll forming technology

Roll forming technology adopts two-roll horizontal frame for rough forming and fine forming, and some vertical roll frames are set between the horizontal frames. For larger welded pipes, in order to improve the quality of deformation and reduce the speed difference, the roller adopts a combined roller. Because high frequency welded pipe equipment has fewer space constraints and greater adaptability, it can produce thin-wall welded pipes and is also suitable for thick-wall welded pipes. This roll forming technology has been used for a long time. However, a set of rolls is required for each size of welded pipe. Therefore, the more types and specifications of welded pipes, the greater the number of rolls and the greater the cost. In the absence of a rapid roll change device, the roll change time is very long, and generally requires 1 to 2 shifts of work time, which reduces the production efficiency and increases the product cost. Therefore, it is not suitable for small batch, multi-variety welded pipe production.

Why does the used roll forming machine flying saw saw lack of lubrication?
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.
