Characteristics of pipe bender

Pipe bender is a general mechanical composition: it is composed of base, reducer transmission device transmission arm, sliding sleeve, fixed bracket, eccentric fixture, fixed fixture, Angle plate, etc. It can be processed and bent with different angles and different bending radii for pipes of various specifications without mould. Applicable bending Angle can reach 120°, bending pipe diameter range of φ 15 - φ 40, bending radius of 5-10 times. Small in size and light in weight. With wheels and movable legs, it is convenient to move, operation, labor saving, high work efficiency. Compared WITH the traditional hydraulic and mechanical pipe bender, it saves the mold and is suitable for the bending pipe in the work of water supply, gas supply and heating, electric wire and cable protection pipe.

Pipe bender is widely used in pipeline prefabrication in electric power, petroleum, chemical industry, navigation, nuclear industry and other engineering fields. However, the wave fold of pipe bender is obviously larger at the arc starting point, especially when the bending radius is less than 3Do (Do is the outer diameter of pipe), the wave fold of inner arc is larger, which seriously affects the appearance quality of the product. This is a problem that domestic pipe bender can not solve for decades and also needs to be solved urgently: refer to the operation manual of electric oil pump. First, the working cylinder is screwed into the internal thread of the square stop block, so that the wheel mounted on the bracket at the rear end of the cylinder is downward.

, 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 pipe is bent, loosen the oil drain screw and the plunger will reset automatically.
