The use of hydraulic pipe bender in pipe bender production

The use of hydraulic pipe bender in pipe bender production

When the bending pipe produced by the hydraulic 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 hydraulic pipe bender produced by our company is widely used in petroleum, chemical, navigation, aviation and nuclear industry. It has a 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.

This process can avoid the uneven phenomenon of pipe bend wall thickness caused by the tension thinning of the convex edge of pipe wall and the compression thickening of the concave edge of pipe wall.The small radius, thin wall and 180 elbow with uniform wall thickness can be produced by using this process, which can not be achieved by other bending processes.If the design of various technological parameters is reasonable, the thickness of the pipe wall in each part of the bending pipe forming process can be kept constant, that is, it is always equal to the thickness of the straight pipe blank before deformation.The process can be used to produce 45°, 90°, 180° and other bending angles of the same caliber with the same horn mandrel at one time, and the production efficiency is high.

Usage of medium frequency pipe bender :(1) Refer to the operation manual of electric oil pump.(2) first screw the working cylinder into the internal thread of the square block, so that the rear end of the cylinder is mounted on the wheel on the bracket downward.(3), choose according to bend the pipe by the outer diameter of the die set in column fortress, two roller groove which corresponds to die, and then in the corresponding size of the plate hole, then the cover plate, the curved pipe inserted into the slot, then quick joint activities of high pressure oil pipe end part of the back and set on the joint of working cylinder, electric oil pump on the oil drain screw tightening, can bend.When the bend is finished, loosen the oil drain screw and the plunger will reset automatically.
