Member bar bending device

Abstract

The invention discloses a member bar bending device which comprises an engine base, and an elastic mold with an annular curved surface, wherein the elastic mold is arranged on the engine base and can elastically deform along the radius direction of the annular curved surface. In the member bar bending device, the material of the elastic mold is changed into an elastic material, so that a member bar is fuller in deformation under the condition of the curved elastic mold, the stress and strain of internal and external sides are larger, and the spring back angle is reduced. Therefore, by adopting the member bar bending device, the problem that the spring back amount of the member bar after being curved is relatively large can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of tool machinery, and more specifically, relates to a bar bending device. Background technique [0002] The use of the elbow prevents the components from interfering with each other, which can reduce the weight of the overall structure and save raw materials. The elbow also has the function of absorbing impact energy and is widely used in industrial production. However, after the bending of the pipe is completed and the mold is removed, the rebound recovery effect of the pipe reduces the final bending angle and increases the bending radius, thereby reducing the geometric and shape accuracy of the pipe and making the connection between the elbow and other parts Decreased performance and compactness of the overall structure. [0003] To sum up, how to effectively solve the problem of relatively large springback after bending of the bar is an urgent problem for those skilled in the art. Contents of the inve...
