Double-centre wire rewinding machine for wire drawing machine

Abstract

The invention discloses a double-centre wire rewinding machine for a wire drawing machine. The double-centre wire rewinding machine comprises a machine frame, a wire wheel subassembly, a tension mechanism, a meter wire metering subassembly, a wire arranging mechanism, a spool wire rewinding mechanism and a wire rewinding motor, wherein the wire wheel subassembly, the tension mechanism, the meter wire metering subassembly, the wire arranging mechanism, the spool wire rewinding mechanism and the wire rewinding motor are arranged on the machine frame. Compared with traditional wire rewinding machine, the double-centre wire rewinding machine disclosed by the invention has the advantages that the spool wire rewinding mechanism adopts the combination of two groups of contact ball bearings under opposite angles, therefore, a wire rewinding shaft can be stable in rotating along with low vibration and low noise; two spools which are respectively BS200 and NTC210 can perform wire rewinding without replacing the centers; the lifting mechanisms for loading and unloading a spool adopt chain type transmission in a lifting way, and the operation is convenient to carry out; ball screws can be driven through the wire arranging mechanism by utilizing a servo motor, thus, the wires can be precisely layered and flatly arranged; and the tension mechanism adjusts the tension through a balancing weight and an adjusting spring, and the tension mechanism is simple in structure and convenient to adjust. The double-centre wire rewinding machine disclosed by the invention is compact in structure, stable in running, convenient to operate, safe and reliable, and low in noise.

Description

technical field [0001] The invention belongs to the field of wire drawing in the industrial production of metal products, and in particular relates to a double-top wire take-up machine for a wire drawing machine. Background technique [0002] The wire take-up machine is generally used in metal wire drawing machines, strand twisting machines and other wire taking-up occasions. Existing wire take-up machines mainly include wire passing, wire arranging, and wire take-up mechanisms, but in the process of wire passing and arranging, tension is unstable, resulting in uneven winding, uneven winding, and easy wire breakage. The cable adopts electromagnetic cable, pneumatic cable and polished rod cable. The electromagnetic and pneumatic cable cannot realize the adjustable row spacing, and the polished rod cable is not evenly arranged. The top of the I-shaped wheel of the take-up mechanism has only one type of I-shaped wheel mounting surface, and only one type of I-shaped wheel can b...

Problems solved by technology

The existing wire take-up machine mainly includes wire passing, wire arranging, and wire take-up mechanism, but the tension in the process of wire passing and arranging is unstable, resulting in uneven winding, uneven winding, and easy wire breakage

The cable adopts electromagnetic cable, pneumatic cable and polished rod cable. The electromagnetic and pneumatic cable can not realize the adjustable row spacing, and the polished rod cable is uneven.

The top of the I-shaped wheel of the take-up mechanism has only one type of I-shaped wheel mounting surface, and only one type of I-shaped wheel can be used to take up the wire. If other I-shaped wheels are used for the wire take-up, the top needs to be disassembled and replaced with a matching top. It is time-consuming and laborious to use, and different I-wheels use backing plates of different heights when loading and unloading the I-shaped wheels, which is very inconvenient to operate; in addition, the fixed end and the moving end assembly of the I-shaped wheel take-up mechanism use two deep grooves The combined structure of ball bearings and thrust ball bearings is not stable enough and noisy
