Stamping elbow,its full name is stamping welding elbow,is produced through using pressing tool to make the board having the same material with the pipe become a half block of annular elbow and then weld the two half elbow together.Due to the difference of various pipe welding standards,and site operation is usually welding according to pipe weld grade,therefore,it is also known as the two-half welding elbow.

The advantages of the production process of stamping elbow:

The processing efficiency of stamping elbow processing is high,and the operation is convenient,and it is easy to realize mechanization and automation.This is because stamping relies on die and punching equipment to complete the processing.The number of strokes of ordinary presses can reach dozens of times per minute. High-speed pressures can reach hundreds or even thousands of times per minute,and a stamping can be obtained for each press stroke.

Since the die ensures the size and shape accuracy of the stamping part during stamping,and generally does not damage the surface quality of the stamping part,the life of the die is generally long, so the quality of the stamping is stable,the interchangeability is good,and it has the same “all the same” feature.

Stamping can process parts with large size range and complicated shape,such as small timepieces with small clocks,large automotive longitudinal beams, covering parts,etc.,plus cold deformation hardening effect of materials during stamping, strength and rigidity of stamping. Both are higher.

Stamping generally has no chip waste,less material consumption, and no need for other heating equipment. Therefore,it is a material-saving and energy-saving processing method,and the cost of stamping parts is low.

The forming process of the stamping elbow is complicated,and it needs to be welded according to different materials and uses,and gradually formed under a certain pressure.The forming of the punching elbow needs to be carried out according to a certain process,and the corresponding process is strictly followed, otherwise the produced stamping elbow will have quality problems.
