Abstract

The utility model discloses a wire drawing mold for manufacturing tank wires, which comprises multiple wire drawing molds, wherein the apertures of the wire drawing molds are in decreasing distribution according to the wire drawing direction, and the aperture of the final wire drawing mold (1) in the multiple wire drawing molds is 1.315mm. When the technical scheme is adopted, the technical problem which is difficult to understand and difficult to solve for a long time in the tank wire industry is solved, and on the basis of tank wire drawing extension, drawn tank wires meet the accuracy requirement of the minimum diameter size.

Description

A kind of system jar silk thread wire-drawing die

Technical field

The utility model belongs to the copper wires machining technology, relates to the process equipment of jar silk thread, and more particularly, the utility model relates to a kind of system jar silk thread wire-drawing die.

Background technology

At present, the diameter of general jar of silk is 1.38mm.Draw 1.38mm Wiring technology maturation, the wire drawing die aperture is by (mm) 2.67-→ 2.38-→ 2.11-→ 1.90-→ 1.68-→ 1.515-→ 1.395-→ 1.38 proportionings, and the linear diameter of pulling out just in time is 1.38mm.

System jar industry wish that jar silk is thin more good more, but through overtesting, the thinnest diameter again can not be less than Φ 1.30mm for reducing production costs.Therefore Φ 1.30 lines are system jar most popular kinds of industry, can satisfy system jar requirement, again can economical with materials.But draw Φ 1.30 lines, if last one die channel directly joined Φ 1.30mm, the linear diameter of pulling out has only Φ 1.28mm, and this is jar silk industry insoluble again technical barrier of indigestion for a long time.

The utility model content

The problem that the utility model solves provides a kind of system jar silk thread wire-drawing die, its objective is to obtain wire drawing diameter dimension accurately.

To achieve these goals, the technical scheme taked of the utility model is:

System provided by the utility model jar silk thread wire-drawing die comprises the multiple tracks wire drawing die, and its aperture is the distribution of successively decreasing by wire-drawing direction, and the aperture of the final wire drawing die 1 in the described multiple tracks wire drawing die is 1.315mm.

2.67mm, 2.38mm, 2.11mm, 1.90mm, 1.68mm, 1.515mm, 1.395mm, 1.315mm layout are pressed in the aperture of described multiple tracks wire drawing die.

The utility model adopts technique scheme, has solved jar silk industry insoluble again technical barrier of indigestion for a long time, and on the basis that the wire drawing of jar silk is extended, the jar silk of pulling out has satisfied the requirement of minimum diameter accuracy of gauge.

Description of drawings

Below expressed content of this Figure of description and the mark among the figure are briefly explained:

Fig. 1 is a structural representation of the present utility model;

Be labeled as among the figure:

1, final wire drawing die, 2, jar silk.

The specific embodiment

Contrast accompanying drawing below, by description to embodiment, to effect and operation principle, the manufacturing process of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.

The of the present utility model structure expressed as Fig. 1 for a kind of system jar silk thread wire-drawing die, comprises the multiple tracks wire drawing die, and its aperture is the distribution of successively decreasing by wire-drawing direction.

In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realize obtaining the goal of the invention of wire drawing diameter dimension accurately, the technical scheme that the utility model is taked is:

As shown in Figure 1, system provided by the utility model jar silk thread wire-drawing die, the aperture of the final wire drawing die 1 in the described multiple tracks wire drawing die is Φ 1.315mm.

Φ 2.67mm, Φ 2.38mm, Φ 2.11mm, Φ 1.90mm, Φ 1.68mm, Φ 1.515mm, Φ 1.395mm, Φ 1.315mm layout are pressed in the aperture of multiple tracks wire drawing die described in the utility model.

Pass through test of many times and grope, Φ 2.67-→ Φ 2.38-→ Φ 2.11-→ Φ 1.90-→ Φ 1.68-→ Φ 1.515-→ Φ 1.395-→ Φ 1.315 proportionings are pressed in the wire drawing die aperture, and the linear diameter of pulling out just in time is Φ 1.30.The aperture of last one wire drawing die is 1.315 rather than 1.30, and this is an important breakthrough.

Technical know-how foundation of the present utility model:

What the production of jar silk 2 was adopted is to connect to draw (silk) even to move back (fire), the back copper wire deliquescing of annealing, and percentage elongation strengthens, and is thin more big more.In the annealing process, a jar silk 2 also might attenuate, and Φ 1.35mm is a critical dimension just, and is not obvious greater than Φ 1.35mm extension, extends obviously less than Φ 1.35mm.Therefore Φ 1.30mm line can not use Φ 1.30mm mould, but outline is for more greatly.

In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.

Claims

1. a system jar silk thread wire-drawing die comprises the multiple tracks wire drawing die, and its aperture is the distribution of successively decreasing by wire-drawing direction, it is characterized in that: the aperture of the final wire drawing die (1) in the described multiple tracks wire drawing die is 1.315mm.

2. according to the described system of claim 1 jar silk thread wire-drawing die, it is characterized in that: 2.67mm, 2.38mm, 2.11mm, 1.90mm, 1.68mm, 1.515mm, 1.395mm, 1.315mm layout are pressed in the aperture of described multiple tracks wire drawing die.
