Six major forming methods of stainless steel elbow

Stainless steel elbow forming six ways of analysis

First, bending forming method: there are three methods commonly used, one method is called extension method, another method is called stamping method, the third roller method, there are 3-4 rollers, two fixed rollers, an adjustment roller, adjust the fixed roller distance, the finished elbow is bent.

Two, forging and pressing method: the end or part of the pipe is extended by a type forging machine to reduce the outside diameter. The commonly used type forging machine is rotary type, connecting rod type and roller type.

3. Roller method: The core is placed in the tube, and the roller is used to push and press around the tube for round edge processing.

Four, stamping method: in the punch with taper core to expand the tube end to the required size and shape.

Five, bulging method: one is to place rubber in the tube, above the punch compression, so that the tube protruding into shape; Another method is hydraulic bulking, in which a liquid is pumped into the middle of the tube and the pressure of the liquid pushes the tube into the desired shape. This method is used in most bellows.

Six, rolling method: generally do not need a mandrel, suitable for thick wall tube inner round edge.
