Abstract

The invention discloses a wire rod straightening device for a screw. The wire rod straightening device for the screw comprises a rack, a guiding unit, a pre-bending unit, a longitudinal straighteningunit, a transverse straightening unit and an input roller. The pre-bending unit comprises an upper compression roller driven by an air cylinder to move up and down and a lower compression roller located below the upper compression roller and driven by a third motor to rotate. Side compression rollers are separately arranged on two sides of the upper compression roller and the lower compression roller. The longitudinal straightening unit comprises a first straightening box, a plurality of longitudinal straightening wheels fixed to the first longitudinal straightening box and a fourth motor which drives the longitudinal straightening wheels to rotate. The transverse straightening unit comprises a second straightening box, a plurality of transverse straightening wheels fixed to the second straightening box and a fifth motor which drives the transverse straightening wheels to rotate. Heating strips are also separately arranged in the first and second straightening boxes. The wire rod straightening device for the screw can straighten big and small curves of the wire rod.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of screws, in particular to the technical field of a wire straightening device for screws. [0003] 【Background technique】 [0004] The screw preparation process includes steps such as wire coiling, wire drawing and cutting, cold heading, tooth rolling, heat treatment and electroplating. The wire rods are hot-rolled round steel supplied in coils with a diameter of 5 to 9 mm in total and eight specifications. Because they are delivered in coils, they are also called wire rods. Before the wire is used, it usually needs to be straightened by a wire straightening device. The wire straightening device is a device for straightening the wire. It squeezes the wire through the straightening roller to change the straightness of the wire. The traditional straightening machine consists of a frame and two rows of staggered straightening rollers arranged horizontally on the frame. Since the direction of the stra...
