How to use and types of pipe expanding machines
There are many types of pipe expanding machines, which can be divided into CNC pipe expanding machines, hydraulic pipe expanding machines, etc. Hydraulic pipe expanding machines are mainly used in the laying and repair of pipelines in railways, bridges, ships, boilers, etc. It is mainly used for plastic forming of pipes. It has the advantages of multi-function, reasonable structure, simple operation, convenient movement, and quick installation. The hydraulic pipe expanding machine can also be divided into standard type and rotary type according to the different bases. There are manual, automatic, half-cycle, full-cycle and other functions to choose from. Its main feature is the use of a mobile foot switch, which has three functions of automatic start, emergency stop and continuous emergency stop, which is safer.
The two sets of machine heads can be operated separately or simultaneously. In addition to the function of bending pipes, this pipe expanding machine can also use the oil cylinder as a hydraulic jack. Compared with CNC pipe bending equipment, it has the characteristics of low price and easy use. It occupies the leading position in the domestic pipe expanding machine market. The bending clamping ability is stronger, the processing is more precise, and multiple pieces can be processed at the same time. The cyclic operation is more efficient. The pipe expanding machine adopts NC control, which is flexible to operate and powerful. It looks small and exquisite, with a very simple design and easy operation, providing a large bending space.
When using it, first refer to the instruction manual of the electric oil pump. Select the die head according to the outer diameter of the bent pipe, put it on the plunger, put the corresponding grooves of the two rollers toward the die head, and then put it into the corresponding holes, and then cover it with a plate, insert the pipe to be bent into the groove, and then pull the movable part of the quick connector at the end of the high-pressure oil pipe backwards, and put it on the joint of the oil cylinder, and then tighten the screw, and you can bend the pipe. After the pipe expanding machine bends the pipe, loosen the drain screw and the plunger will automatically return to its original position. The CNC pipe expanding machine performs winding bending with one bending radius or two bending radii in a cold state, which is widely used in the bending of various pipe fittings and wires in the automotive, air conditioning and other industries.
