Problems solved by technology

At present, the straightening mechanism of bar often adopts single straightening, and the production efficiency is low
At the same time, many straightening mechanisms can only straighten the curvature of the bar in one direction, and the bar often bends in multiple directions during transportation and processing. In this case, it is difficult for ordinary straightening mechanisms to fully correct the curvature. The bar is straightened, which ultimately affects the quality of the screw
In addition, in the process of bar straightening, there will be friction with the straightening wheel, especially the threaded bar will rotate around its own axis, which will damage the surface of the bar and affect the quality of the best product.

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] Such as Figure 1~3 As shown, the bar straightening mechanism of the present embodiment includes a workbench 1, a traction unit 2 and a straightening unit 3 arranged on the workbench 1, and the straightening unit 3 includes five straightening rollers 31, five straightening rollers 31 is divided into two groups up and down, the upper group is two, the lower group is three, and the upper and lower two groups of straightening rollers 31 are staggered. In order to carry out straightening more effectively, three grooves 311 are provided along the circumferential direction on the straightening roller 31, and the grooves 311 are evenly distributed along the axial direction of the straightening roller 31, and three groups of balls 312 are arranged on both sides and the bottom of the groove 311. , where there are twelve balls 312 on both sides,...

Abstract

The invention relates to a bar straightening mechanism, which includes a workbench, a pulling part, and a straightening part. There are grooves, and balls are arranged in the grooves, and the grooves on the upper and lower two sets of straightening rollers are opposite to form straightening holes for bars to pass through. The bar can be straightened at multiple angles through the straightening hole, and due to the existence of balls, there will not be too much friction between the bar and the straightening roller, and there will be no impact on the straightening roller. The surface is damaged.

Description

technical field [0001] The invention relates to the field of screw forming and manufacturing equipment, in particular to a bar straightening mechanism. Background technique [0002] The first step in screw forming is to straighten the bar required for production. At present, the straightening mechanism of bar often adopts single straightening, and the production efficiency is low. At the same time, many straightening mechanisms can only straighten the curvature of the bar in one direction, and the bar often bends in multiple directions during transportation and processing. In this case, it is difficult for ordinary straightening mechanisms to fully correct the curvature. The bar is straightened, which ultimately affects the quality of the screw. In addition, in the process of bar straightening, there will be friction with the straightening wheel, especially the threaded bar will rotate around its own axis, which will damage the surface of the bar and affect the quality of ...
