【概要描述】When the used welded pipe machine is used to make welded pipes, springback is generally not a very prominent problem. With the development of China's welded pipe industry, the application of various new materials in the welded pipe industry, the addition of various low-alloy and alloy steel welded pipes, stainless steel welded pipes and other metal elements, and the development and production of alloy welded pipes, they rebound during forming has become a more prominent problem.

When the used welded pipe machine is used to make welded pipes, springback is generally not a very prominent problem. With the development of China's welded pipe industry, the application of various new materials in the welded pipe industry, the addition of various low-alloy and alloy steel welded pipes, stainless steel welded pipes and other metal elements, and the development and production of alloy welded pipes, they rebound during forming has become a more prominent problem.

 

Used welded pipe machine

 

How to overcome the springback of the used welded pipe machine:

(1) Appropriately increase the deformation of the forming roll

When designing the forming rolls of certain materials with large springback or large-size welded pipes, the factor of large springback needs to be considered, and the deformation of each forming roll should be increased appropriately, so that the shape of the tube blank can be made after springback. Achieve the required shape. Especially for the edge part of the metal band, this method is helpful to prevent the production of peach-shaped tubes.

 

(2) Using thermoforming method

Since the yield strength and elastic modulus of metal materials will decrease with the increase of temperature, the use of thermoforming method can reduce the amount of springback during molding.

 

Used welded pipe machine

 

(3) Adopt asymmetric molding method

The asymmetric forming method refers to the use of two sets of asymmetric forming rolls before the squeeze roll, so that the tube blank produces two asymmetric deformations before entering the squeeze roll. As long as the design of the asymmetric roller is reasonable, the tube blank can keep the two edges in close contact within a certain distance under the action of the two sets of squeezing rollers to meet the welding requirements.

 

The above are three ways to overcome the springback when the used welded pipe machine is used to manufacture welded pipes.

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.
