Stainless steel reducer

The stainless steel reducer tube moves along the die cavity and shortens the forming process by limiting the axial direction along the tube blank. According to the diameter of the reducer, it is divided into one limit forming or repeated limit forming. Expanding tube is less than the diameter pipe end diameter, with inner diameter along the tube expanding die forming. The diameter expanding technology is mainly used to deal with the reducer whose diameter is bigger than that of the diameter reducing tube, and sometimes the method of enlarging and reducing diameter is merged according to the forming demand of the material and the commodity. In the process of reducing or enlarging the deformation limit, the cold pressing or hot pressing should be chosen according to the different material and the change of diameter. Pipes have alloy reducer, molded reducer and double flanged reducer.

The stainless steel reducer is usually used as cold pressure as possible, but the condition of severe working hardening, the condition of thicker wall thickness, or the material of alloy steel should be selected for hot pressing. In addition to the use of steel tubes for the production of materials, for some standards of different diameter tube can also be used in sheet metal stamping forming technology for production. The shape of the die used in the drawing is planned according to the dimension of the inside and outside table of the diameter reducer. The stamping and drawing forming of the steel plate after blanking is done by the blanking die. Eccentric different diameter pipe used in steel pipe material production for different diameter pipe, reducing pipe necking forming technique is with different diameter Guan Daduan tube diameter flat in forming model. For some standard reducer, the steel plate can be produced by stamping forming technology. The shape of the die used in the drawing is planned according to the dimension of the inside and outside table of the diameter reducer, and the stamping and drawing of the steel plate after blanking is done by the blanking die.
