Continuous automation production method and equipment for stainless steel harness wire

Abstract

The invention discloses a continuous automation production method and equipment for a stainless steel harness wire. The production method comprises the following steps of punching, chamfering for the first time, chamfering for the second time, broadening holes, feeding and aligning, shaping and shearing for harness wire production by a positioning time delay control device, wherein all steps are continuously and automatically finished. The production equipment comprises harness wire conveyors, wherein a punching punch press, a primary chamfering punch press, a secondary chamfering punch press, a broadening hole punch press and a shaping punch press are successively arranged above the harness wire conveyors along the conveying direction of the harness wire; the harness wire conveyor between the punching punch press and the primary chamfering punch press is provided with the positioning time delay control device; and the harness wire conveyor between the broadening hole punch press and the shaping punch press is provided with an aligning traction device. In the continuous automation production method and equipment, the continuous automation production of the stainless steel harness wire can be realized, the output is drastically improved, and the energy consumption is obviously lowered. The produced harness wire has the advantages of stable quality, smooth edge and no burr for punching, smooth and flat harness wire surface and long service life, and the harness wire freely slides without resistance.

Description

technical field [0001] The invention relates to a continuous automatic production method and equipment for stainless steel heddles. Background technique [0002] Heddles are used on looms. There are three ring holes in the upper, middle and lower positions of each heald. The middle ring hole is small and called the middle hole, which is used for threading the yarn warp; of. Hundreds of healds pass through the heddles or hangers to form a heald frame or heddles, which are used in the belly of the loom, like a multi-layer screen seal. The control and warp threads are alternately divided into upper and lower layers of weaving holes, allowing the weft threads to pass through to weave cloth. [0003] Heddles have various specifications, and the specifications used for weaving cotton, hemp, silk, wool, etc. are different. [0004] Healds are a bulky consumable accessory in textile production. China, as a densely populated area of ​​global textile enterprises, consumes tens of ...

Problems solved by technology

[0005] Traditional healds are made of stainless steel. Since the stainless steel material for healds is rolled and slender, in order to achieve the purpose of continuous automatic stamping, it is necessary to solve the problem of continuous and accurate delivery of stainless steel strips in production. However, the existing general-purpose technology is difficult to achieve

For example, cylinder conveying, roller conveying, punch crankshaft conveying, inclined wedge conveying, etc., even if this kind of conveying is equipped with a guide needle, it is difficult to achieve synchronous and accurate conveying of stainless steel strips to multiple stamping equipment

[0006] Therefore, the existing domestic technologies for producing stainless steel healds are all single punching, and the roughness of the product section and the burrs generated are all manually polished.

The healds produced in this way have many stamping processes, poor product consistency, and high labor costs.

In addition, in order to make the yarn lint-free and uninterrupted when the yarn moves in the heald hole, most of the domestic methods use a separate polishing process for the center hole, which is time-consuming and laborious.
