[CN 201620737477.2] Steel Pipe Rotary Pulse Cold Forging Unit
[CN 201620737477.2] Title of Steel Pipe Rotary Pulse Cold Forging Unit: Steel Pipe Rotary Pulse Cold Forging Unit Application Number: CN 201620737477.2 Applicant: Wang Jianbo Application Date: 2016-7-14 Patent Type: Utility Model The utility model discloses a steel pipe rotary pulse cold forging unit, the utility model includes an axial conveyor arranged in sequence along the forward direction of the steel pipe to convey the raw material pipe forward, a radial cold forging machine for cold forging the raw material pipe, and an axial traction machine for pulling the finished pipe forward after the end of the raw material pipe leaves the axial conveyor. The utility model realizes the forging processing of reducing the diameter and wall of the raw material pipe through high-frequency pulse continuous reciprocating motion, and the cold forging production speed is greatly improved, reaching 1m 4 m/min, the steel pipe after cold forging has high dimensional accuracy and can achieve the purpose of non-cutting processing: and the product has good mechanical properties, increased surface hardness, increased tensile strength, yield strength and fatigue strength; eliminating the deformation stress of ingredients, no need to do Failure treatment; the production process of the utility model does not require heading, pickling, saponification, phosphating and other processes, so it will not cause any pollution to the environment.
