Wear-resistant pump tube processing method

There are many types of pump tubes, including wear-resistant pump tube, thick-walled pump tube, thin-walled pump tube, wear-resistant pump many also belong to the category of machining category, the most used stamping method, forging method, Rolling method, bulging method, stretching method, bending method, and combined processing method. Wear-resistant pump tube machining is an organic combination of machining and metal pressure machining.

Wear-resistant pump tube is now an example as follows:

Forging method: With a forging machine to be part of the end of the pipe to be punched, so that the outer diameter to reduce the commonly used swaging machine rotary, connecting rod, roller type.

Stamping method: The taper core is used to expand the pipe end to the required size and shape on the punch press.

Roller method: placed in the tube core, the outer wheel with a push, for round edge processing.

Rolling method: General mandrel, suitable for thick-walled tube inside the round.

Bending forming method: There are three methods are more commonly used, one method called extension method, the other method is called stamping method, the third is familiar roller method, there are 3-4 rollers, two fixed rollers, an adjustment Roller, adjust the fixed roller distance, finished pipe is curved. This method is widely used, if the spiral tube production, the curvature can be increased.

Bulging method: one is placed in the tube of rubber, the top with a punch compression, the tube protruding shape; the other method is hydraulic bulge forming, the middle of the tube filled with liquid, liquid pressure drum into the desired shape.
