| Development and use of aligning machine
With the development of pipes all over the world, the company's grid pipe machine and machine will produce pipe fittings of the production of steel pipe forming, in the production of steel pipe according to the requirements of customers to produce a variety of different types and calibers of steel pipe. Steel pipe processing is now with the speed of development, especially in the construction of the city and petrochemical pipeline installation is the company's steel pipe machine production.
Steel pipe material is divided into: carbon steel, alloy steel, stainless steel, etc. Lattice pipe machine in the process of use, simple operation, high production efficiency, is the steel pipe industry customers general equipment.
The aligning machine production line adopts the combination of molds, direct production and processing technology, with the characteristics of fast production and processing without removing the main shaft.
The straightening machine is mainly used to form steel pipes. The main steel pipes processed are divided into spiral pipes, square pipes and other steel pipes.
Using the skin effect and proximity effect of high frequency current, the metal in the welded pipe to be welded can be heated to the melting state quickly, and welding can be realized by extrusion. High-frequency welding usually uses a current frequency range of 300-450KHZ and a power range of 100-1000KW. High frequency welder is used at present. High frequency welding equipment is one of the core equipment of high frequency welded pipe production line.
Although the sizing device of HF welded pipe is set in radial direction, it still has bending degree in the length direction. Therefore, the high frequency welded pipe is straightened. The straightener is generally divided into pressure straightener and roll straightener. The working principle of the roller straightener is as follows: the high-frequency welded pipe moves forward in a straight line between the slanted hyperboloid straightening rollers and rotates at the same time. The high-frequency welded pipe achieves the purpose of correction through several elastic-plastic bending of the high-frequency welded pipe in the straightening roller.
The strip is levelled before the formation of the straightener. It is usually composed of upper frame, lower frame and transmission device, etc., with five rolls and seven rolls, etc. In the high-frequency pipe welding production line, there is usually a clamping roller in front of the leveler.
