Description

Steel wire heald

Technical Field

The utility model relates to a steel wire heald.

Background

Steel wire harnesses are widely used in textile jacquard looms. The traditional steel wire heald is characterized in that two steel wires are arranged in parallel, a rod body is formed by welding the two steel wires in the middle, heald lugs are wound at the two ends of the rod body by a forming machine, local soldering tin between the two steel wires is split in the middle of the rod body, a washer mounting hole is formed, a washer with a hole is embedded in the washer mounting hole and is welded, and the steel wire heald is low in machining efficiency and high in production cost. When the jacquard loom works, the warp threads pass through the thread penetrating holes to realize warp feeding, and the steel wire heald moves up and down to drive the warp threads to move up and down, so that the warp and weft weaving operation is completed. However, the rod body is formed by welding two steel wires in parallel, so that the welding surface is small, the bonding force is poor, the phenomena of rod body cracking and washer falling can be generated in use, and the service life of the steel wire heald is short.

Disclosure of Invention

The utility model provides a steel wire heald which has the advantages of low production cost, high processing efficiency, firm connection and long service life.

In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides a steel wire heald, includes harness wire and china department, the harness wire comprises a flat metal strip, and the upper and lower both ends of harness wire are bent and are formed the heald ear, and the harness wire middle part is got one section and is formed two fixed strips along the thickness direction of length direction broken harness wire, the coupling part of two fixed strips and harness wire forms the china department mounting hole, be equipped with the wire drawing hole in the middle of the china department, the china department left and right sides limit respectively is equipped with a draw-in groove, two fixed strips imbed respectively and correspond the draw-in groove and form the cooperation to both ends reduce the china department mounting hole about two fixed strips through rotatory winding, form closely to cooperate with the china department.

The beneficial effects provided by the utility model are as follows: whole harness wire comprises a flat metal strip, can directly produce processing harness wire raw and other materials through the mode of punching press or cutting when producing the harness wire, low in production cost, machining efficiency is high, get one section two fixed strips that cut off its punching press formation in harness wire middle part simultaneously, and fix the china department in the china department mounting hole through two fixed strips of rotatory winding, and through the cooperation of fixed strip and draw-in groove, make the china department firmly install in the china department mounting hole, whole course of working is very simple and convenient, the finished product is firm, long service life.

Furthermore, the washer is of a metal block structure, and the washer is simple in structure, strong in firmness and high in machining efficiency.

The utility model is described in further detail below with reference to the figures and examples.
