Device for straightening steel wire split from steel wire rope

Abstract

The invention discloses a device for straightening a steel wire split from a steel wire rope. A base disc, three supports, a stepping motor, a ball screw, two guide rails, a clamping mechanism, a straightening wheel frame, four straightening wheels, a supporting frame, a synchronous belt, two synchronous belt wheels, a feeding assembly and a pre-tightening mechanism are installed inside an enclosure. The steel wire to be straightened penetrates from a point B to a point A, sequentially passes through the pre-tightening mechanism, the feeding assembly and the four straightening wheels, and is clamped by the clamping mechanism. The stepping motor is started to drive the ball screw to rotate, and then the two synchronous belt wheels and the straightening wheel frame are further driven to rotate simultaneously, so that the steel wire can be straightened in an omnibearing mode. The ball screw rotationally drives the clamping mechanism to move leftwards. The steel wire is pulled out from the point B to the point A, and straightening of the steel wire is achieved. An experiment with the device shows that the split steel wire with the diameter below 3 mm can be straightened, and the requirements of tensioning, twisting and repeatedly bending the steel wire subsequently are met. In addition, the surface of the steel wire is basically not damaged, the performance of the steel wire is not damaged, equipment is easy to operate, and the operation speed is adjustable.

Description

technical field [0001] The invention relates to a steel wire rope detection device, in particular to a device for straightening steel wire rope split strands. Background technique [0002] Steel wire rope is an important construction engineering material, which is widely used in elevators, mines, buildings, and bridges. The steel wire rope product standard requires steel wire inspection after splitting, and the inspection items require tensile test, torsion test, repeated bending test, etc. Steel wire Must be straight. The split steel wire of the steel wire rope is in the shape of a spiral, with high hardness and high elasticity, especially for those with a larger diameter (more than 1mm per wire) and higher strength (more than 1470MPa), it is difficult to straighten by hand. At present, the commonly used method is to knock flat with a wooden mallet. This kind of manual straightening is labor-intensive, dangerous, and easy to hurt people. At the same time, the surface of th...

Problems solved by technology

At present, the commonly used method is to knock it flat with a wooden mallet. This kind of manual straightening is labor-intensive, dangerous and easy to hurt people. At the same time, the surface of the steel wire is seriously deformed after being struck vigorously, which will affect the follow-up test results.

According to the needs of steel wire rope detection work, this subject develops a device that can automatically straighten steel wire rope and split steel wires from the actual situation, so as to solve the problems of inaccurate straightening, high risk and inaccurate results in manual straightening.
