The development and use of the trellage machine

With the development of pipe materials all over the world, the company produces the pipe grilling machine and the machine to manufacture the steel pipe for the production of pipe fittings, in the production of steel pipe according to the requirements of customers to manufacture a variety of different types and diameters of pipe.The processing of steel tubes by technicians is now developing with the speed, especially in the construction of cities and the installation of pipelines in the petrochemical industry.

The material of steel pipe is divided into: carbon steel, alloy steel, stainless steel and so on.In the process of use, the tube grilling machine is simple to operate, high production efficiency, and is the common equipment for customers in the steel pipe industry.

The production line of the pipe lacing machine adopts the combined mold, direct production and processing technology, and has the characteristics of fast production and processing without dismantling the main shaft.

Pipe grilling machine is mainly used for forming steel pipes, which are divided into spiral pipes, square pipes and other steel pipes.

Using the skin effect and proximity effect of the high frequency current, the metal at the welding place of the welded pipe can be heated to the molten state quickly, and the welding can be realized by extrusion.High frequency welding usually uses a current frequency range of 300-450 kHz and power of 100-1000 kW.High frequency welder is currently used.High frequency welding equipment is one of the core equipment of high frequency welded pipe production line.

Although the diameter setting device of the high frequency welded pipe is fixed in the radial direction, the bending degree still exists in the length direction.Therefore, the high frequency welded pipe straightening, straightening machine is generally divided into pressure straightening machine and roller straightening machine.The working principle of the roll straightener is: the high frequency welded pipe in the inclined hyperboloid straightening roller between the straight line forward at the same time also rotating motion, through the high frequency welded pipe in the straightening roller back and forth many times elastoplastic bending so that the high frequency welded pipe to achieve the purpose of correction.

Flatten the strip before forming the tube lacing machine.It is generally composed of upper frame, lower frame and transmission device, with five rollers and seven rollers, etc. In the high-frequency welded pipe production line, a pinch roller is usually set before the leveler.
