Forming steps of stamping elbow

The forming process of stamping elbow is complex, which needs to be welded according to different materials and uses, and gradually formed under a certain pressure. The forming of stamping elbow needs to be carried out according to a certain process, and the corresponding process should be strictly followed, otherwise the quality problems will arise. The basic technological process of forming large stamping elbow is to weld a polygonal annular shell or a closed polygonal sector shell with two ends. When the pressure medium is filled in the shell, internal pressure is applied, and the cross section changes from polygonal to circular gradually under the action of internal pressure, and finally to a circular annular shell. This is the process of forming large elbow.
forming steps of stamping elbow
1. Stamping is highly efficient, easy to operate, easy to achieve mechanization and automation, this is because stamping is to rely on stamping die and stamping equipment to complete processing, ordinary press stroke times per minute can reach dozens of times, high-speed pressure per minute can reach hundreds or even thousands of times, and each stamping stroke can be. You can get a punching piece.
2. Stamping is a kind of material-saving and energy-saving processing method, and the cost of stamping parts is lower.
3. Stamping can produce parts with large size range and complex shape, such as stopwatch as small as clocks and watches, automotive longitudinal beam, panel, etc. The strength and stiffness of stamping are higher due to the cold deformation and hardening effect of materials during stamping.
4.The stamping quality is stable and the interchangeability is good because the die guarantees the dimension and shape precision of the stamping parts, and generally does not destroy the surface quality of the stamping parts, while the life of the die is generally long, so the stamping quality is stable and the interchangeability is good, and it has the characteristics of "exactly the same".
