A wire drawing and unwinding device for surface treatment of metal products

Abstract

The invention discloses a wire drawing and unwinding device for surface treatment of metal products. In the present invention, the joint use of the first clamping strip, the limiting groove, the spring, the protective block and the telescopic mechanism is used, and the first clamping strip and the second clamping strip in the inner cavity of the limiting groove are clamped and limited, so that the movable rod can be stabilized. Placement, easy to adjust, through the use of the spring, the spring can drive the movable rod to move backward automatically, preventing the movable rod from breaking away from the limit slot, and the line is limited by the protective block, which effectively prevents the line from breaking away from the bottom of the second pulley. The use of the telescopic mechanism achieves the purpose that the spring can move up and down while being limited by the movable block, and solves the problem that the existing wire drawing and unwinding device cannot adjust the tightening degree of the wire during use, which may easily cause the wire to fall off the pulley, and the protection effect is low The problem.

Description

technical field [0001] The invention relates to the technical field of surface treatment of metal products, in particular to a wire drawing and unwinding device for surface treatment of metal products. Background technique [0002] Metal surface treatment is a process of artificially forming a surface layer on the surface of a base material with mechanical, physical and chemical properties different from that of the base. The purpose of surface treatment is to meet the corrosion resistance, wear resistance, decoration or other special functions of the product. Require. [0003] In the process of metal surface treatment, a wire drawing and unwinding device is required, but the existing wire drawing and unwinding device cannot adjust the tightening degree of the wire during use, which may easily cause the wire to detach from the pulley, and the protective effect is low, which reduces the use of the surface treatment of metal products. The practicability of the wire drawing an...
