An adjustable stress relief mechanism for steel cold rolling

Abstract

The invention provides an adjustable cold-rolled stress relief mechanism for steel bars, which includes a base plate, the left edge position and the right edge position of the upper end of the base plate respectively fix the second support plate and the first support plate, the first support plate and the second support plate Both support plates are provided with guide holes for steel bars to pass through, and at least two curved assemblies with equal spacing are fixed horizontally on the top of the bottom plate. Bending parts for multi-directional bending of steel bars are fixed between the vertical plates, and two control parts are fixed up and down on the vertical end faces of the opposite sides of the two vertical plates, and the four control parts There are traction ropes inside, and the four traction ropes respectively pass through the circular grooves at the corresponding positions on the two vertical plates and are connected with the upper and lower positions of the front and rear ends of the bending piece. The invention increases the multi-directionality of steel bending, Improve the stress release limit inside the steel bar and increase the elongation of the steel bar.

Description

technical field [0001] The invention relates to an adjustable stress relief mechanism for steel bar cold rolling, which belongs to the technical field of steel bar stress relief. Background technique [0002] Generally, the strength of the smooth round steel bar of the wire rod is improved after cold rolling, and the same diameter can withstand a greater breaking force, but the result is a decrease in elongation, which is also a disadvantage of cold rolled steel bars. In order to restore the elongation of the rolled steel bar, a stress relief device is generally installed at the rear of the rolling mill to increase the elongation by eliminating stress. [0003] At present, the method used by the stress relief device is generally repeated bending. For example, in the shaft type steel bar stress relief machine whose Chinese patent publication number is CN204486460U, all the bending wheels used for bending the steel bar are on one plane. When the steel bar passes through the be...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a cold-rolled steel bar adjustable stress-relief mechanism to solve the problem that all the bending wheels for bending steel bars proposed in the background art are on one plane, causing the steel bar The deformation is only in one direction, and the effect of stress relief is not thorough. The invention increases the multi-directionality of steel bending, improves the stress release limit inside the steel bar, and increases the elongation of the steel bar.
