Forming Process Of Stainless Steel Elbow

Forming process of stainless steel elbow pipe

The push bending method is a common method for bending stainless steel pipe fittings and is mainly used for elbow bending. According to the characteristics of different bending activities, it can be divided into cold push bending and hot push bending of the mandrel.

Cold push bending uses different bending experimental devices. Push the bent tube blank in an ordinary hydraulic press or crank press, and press the stainless steel straight tube blank into the mold at room temperature to form a stainless steel elbow, which is suitable for cold push bending of stainless steel. The bending radius of the elbow becomes smaller, the minimum bending radius is relative r≤d≤1, the ovality of the elbow section is small (≤3%≤5%), the outer pipe wall gradually becomes thinner (≤9%), the structure is simple, and no special The equipment has high production efficiency, but the design of stainless steel elbows of different thicknesses requires t ≥ 0.06. Otherwise, due to poor stiffness, the steel billet will often lose stability, causing the elbow to wrinkle or deform.

Under the action of special axial thrust, the hot push rod pushes the bending deformation of the tube at the axial center to expand in the circumferential and axial directions, and the small diameter tube is pushed into the large diameter elbow.
