Adjustable bent steel strip straightening machine

Abstract

The invention relates to an adjustable bending steel bar straightening machine, comprising a steel bar conveying system and a bending straightening system. Straightening unit, the unit connection sequence from left to right is horizontal conveying unit, horizontal straightening unit, horizontal conveying unit, vertical straightening unit and vertical conveying unit; the present invention can correct the bent steel bar in all directions through the horizontal straightening unit and the vertical straightening unit; The heating wire of the bending correction system provides heat to promote the temperature of the steel bar to change the internal structural stress of the steel bar, so that the steel bar becomes straight and no longer bends after correction; the shear difference, distance adjustment nut and distance adjustment screw of the bending correction system can be used. Adjust the gap of the straightening wheel to avoid the ordinary replacement of the straightening wheel; the straightening is comprehensive, the work efficiency is high, the adjustment is convenient, the straightening quality is improved, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of production of steel cable clips, in particular to an adjustable straightening machine for curved steel bars. Background technique [0002] At present, in the cold heading production process of steel cable clips, the raw steel strips used for the production of steel cable clips are rolled into a coil shape due to transportation and storage needs. The steel bar is transported to the cold heading machine for cold heading production; however, the existing steel bar straightening machine only has a horizontal straightening device and the stress of the bent steel bar cannot be eliminated after straightening, resulting in the steel bar still being bent. It affects the quality of the steel cable clips produced by cold heading steel bars; in addition, the straightening wheel of the straightening device of the existing steel bar straightening machine cannot adjust the size of the correction gap. When producing diff...

[0002] At present, in the cold heading production process of steel cable clips, the raw steel strips used for the production of steel cable clips are rolled into a coil shape due to transportation and storage needs. The steel bar is transported to the cold heading machine for cold heading production; however, the existing steel bar straightening machine only has a horizontal straightening device and the stress of the bent steel bar cannot be eliminated after straightening, resulting in the steel bar still being bent. It affects the quality of the steel cable clips produced by cold heading steel bars; in addition, the straightening wheel of the straightening device of the existing steel bar straightening machine cannot adjust the size of the correction gap. When producing different types of steel cable clips, different sizes of steel In order to achieve a better correction effect, it is necessary to replace the correction wheels with different radii, which is cumbersome to operate, affects the efficiency of production, and wastes manpower and material resources.
