The forming process of push elbow is complex, which needs to be welded according to different materials and USES and gradually formed under certain pressure. The forming of push elbow should be carried out in accordance with certain working procedure, and the corresponding process should be strictly followed. Otherwise, quality problems will occur in the production of push elbow.

The forming process of bending pipe

The production and processing of push elbow need to use this process for production, production in strict accordance with the rules to ensure the production of push elbow elbow has a good quality assurance.

The forming process of push elbow is complex, which needs to be welded according to different materials and USES and gradually formed under certain pressure. The forming of push elbow should be carried out in accordance with certain working procedure, and the corresponding process should be strictly followed, otherwise the quality problems will be caused by the production of push elbow elbow.

The basic process of push elbow forming technology is as follows: welding a polygonal annular shell with polygonal cross section or a polygonal fan-shaped shell with two closed ends. When the pressure medium is filled inside, internal pressure is applied. Under the action of internal pressure, the cross section gradually turns into a circular annular shell from a polygon. This is the process of pushing elbow molding.

According to the need, a circular ring shell can be cut into 4 90 degree elbow or 6 60 degree elbow or other specifications elbow elbow, this process is suitable for manufacturing elbow elbow middle diameter and elbow inner diameter ratio of more than 1.5 any specification of large push elbow, is the ideal method for manufacturing large push elbow at present. This process molding method is used in the production of different elbow bend pipe, showing good use value in different fields, so that the process in different elbow bend pipe operation has a good value.

The advantages of the forming process of push elbow are mainly manifested in the following aspects:

(1) tube billet is not needed as raw material, which can save the cost of tube making equipment and die, and push elbow elbow with arbitrarily large diameter and relatively thin wall thickness can be obtained. This kind of push elbow bend is made of special raw material, which does not need to add the raw material of tube billet.

(2) the blank for pushing elbow bend is flat plate or developable surface, so the cutting is simple, the precision is easy to ensure, the assembly and welding is convenient, the raw material is easy to control in the processing, the operation is simple, there are no complicated procedures, and the welding and assembly is convenient.

(3) because of the above two reasons, the manufacturing cycle can be shortened and the production cost can be greatly reduced. Because no special equipment is needed, it is especially suitable for processing push elbow on site.
