Reducing elbow

Reducing elbow is also called reducing elbow, which is a pipe fitting used to connect two pipes with different diameters as steering pipes. It is a production technology that uses a standard elbow blank to cut into a V-shaped elbow, and then applies pressure. With the power of conventional or one-to-one stamping equipment, the elbow blank is directly subjected to deformation force in the mold and deforms, so as to obtain product parts with certain shape, size and performance. Under the effect of pressure, it gradually becomes round, becomes a circular ring shell, and is welded into shape, Then use the elbow to adjust the equipment and the adjustment is complete. This process is called "sliver drawing" in the industry. Pipe blank, die and equipment are the three elements of reducing elbow processing. Reducing elbow machining is a metal cold deformation processing method. It is one of the main methods of metal plastic processing (or pressure processing), and also belongs to material forming engineering technology
