Online straightening mechanism for continuous cold drawing and unwinding of finished oxygen-free copper rod

Abstract

The invention discloses an online straightening mechanism for continuous cold drawing and unwinding of a finished oxygen-free copper rod, and relates to the technical field of metal rod straightening devices. The online straightening mechanism comprises a guide assembly, a primary straightening assembly, a secondary straightening assembly and a reinforcing and shaping assembly which are sequentially arranged in the advancing direction of an oxygen-free copper rod body, the guide assembly comprises a fixing pipe, and a plurality of guide wheels are arranged on the periphery of the inner axis of the fixing pipe at equal intervals by a lap. The guide wheels are installed on the inner wall of the fixing pipe through a fixing rotating shaft and a supporting frame, and the side surfaces of the guide wheels are in a concave groove shape. By arranging the guide assembly, the primary straightening assembly, the secondary straightening assembly and the reinforcing and shaping assembly, the problems that most of existing online straightening mechanisms are used for temporarily and intensively straightening, and internal stress is gradually released after oxygen-free copper rods come out of the straightening mechanism, as a result, the straightened oxygen-free copper rod is insufficient in structural stability and has a bending angle are solved.

Description

technical field [0001] The invention relates to the technical field of straightening devices for metal rods, in particular to an online straightening mechanism for continuous cold drawing and unwinding of finished oxygen-free copper rods. Background technique [0002] As the raw material for oxygen-free copper wire production and processing, oxygen-free copper rods are packaged in rolls when purchased, and then before cold-drawing production and processing, the coiled oxygen-free copper rods need to be unrolled and straightened continuously on-line , and then it can be processed by the processing equipment. Most of the existing online straightening mechanisms are short-term centralized straightening, that is, the overall length of the straightening mechanism is relatively small. When the bent oxygen-free copper rod passes through the straightening mechanism, it is reversely bent and squeezed by standard-shaped modules and components. Pressure makes it become a straight rod....

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides an online straightening mechanism for continuous cold drawing and unwinding of finished oxygen-free copper rods, which solves the problem that most of the existing online straightening mechanisms are short-term concentrated straightening, and the oxygen-free copper rods are straightened After the straightening mechanism comes out, the internal stress is gradually released, resulting in insufficient structural stability of the oxygen-free copper rod after straightening, and problems with the bending angle
