Main composition of medium frequency pipe bender
Main composition of medium frequency pipe bender
Intermediate frequency pipe bender is for petrochemical, electric power, urban construction engineering, equipment deployment of important set of equipment, its what principle is the use of intermediate frequency power supply for steel pipe (include low alloy steel, stainless steel tube, etc.) hold heat, will be at a constant speed steel pipe at the same time, make the heating unit of steel pipe to walk along a predetermined path to form a certain curvature radius and Angle of bend.Features: the bent pipe has small deformation, small wall thickness difference, no stress.Bending radius 0-1800 adjustable for simple controls.
The hydraulic system of medium frequency pipe bender is composed of 9 hydraulic cylinders and 2 hydraulic motors.The main clamping cylinder always ensures that the pipe is firmly on the rotary arm through the clamp when bending the pipe to ensure that the pipe is bent according to the predetermined radius;The guide and clamp cylinder plays a role in helping the clamp pipe, and has the function of guiding and supporting.The propulsion cylinder provides power for the pipe bender when it is held in the bending pipe;When the auxiliary clamping cylinder is bending the pipe, the elbow is firmly placed on the pushing car to prevent the vibration of the pipe when it is advancing.The positioning clamping cylinder locates the main chuck on the rocker arm guide rail to prevent it from moving due to the force in the matter;Positioning hydraulic motor to realize the movement of rocker arm platform;Reset the motor is to reset the rocker arm when the elbow is broken.In the hydraulic system of the pipe bender, the main bending clamping cylinder, the guide clamping cylinder, the auxiliary clamping cylinder, the propulsion cylinder and the positioning clamping cylinder all accept the hydraulic control one-way locking valve to eliminate the loss of pressure and ensure the reliable clamping and bending action in the process of pipe bending.
The use of pipe bender for pipe bender production
When the bending pipe produced by the pipe bender is processed and formed, the convex side pipe wall is thinned or cracked, the concave side pipe wall is thickened or wrinkled under pressure, and the flat pipe section is changed, which is the technical problem that troubles the processing industry.The problem of lack of theoretical guidance in pipe bending processing technology in China has been fundamentally changed.After the research results are applied to industrial production, good social and economic benefits have been obtained.
The traditional bending pipe will cause the convex edge pipe wall to be pulled and thinned, the concave edge pipe wall to be compressed and thickened, so that the place where the bending pipe is stressed is weak, and the place where the stress is small is thick, which is unreasonable.This process defect is one of the important reasons for the bending pipe burst problem, but also the hidden danger of causing explosion, fire and other malignant consequences.
The bender produced by our company is widely used in petroleum, chemical, navigation, aviation and nuclear industry. It is of special significance in the environment of high temperature and high pressure.The theory of plastic forming of wall thickness elbow and the related research results of process equipment have been adopted by many heavy enterprises, and the produced elbow has been widely used in the national key construction project of ten thousand tons ethylene project and many petrochemical enterprises.After inspection, the quality of the bending pipe exceeds the national similar products, not only replaced the import, but also exported to Japan, the United States and so on, which has produced remarkable economic and social benefits.
