Description

[0001] Apparatus for cutting wire [0002]

The present invention relates to a wire cutting apparatus, and more particularly, to a wire cutting apparatus capable of preventing a wire from being entangled even when cut to a long length.

A wire drawing machine is a device for drawing a wire having various diameters as is generally known, and uses a principle of pulling a wire rod, a wire rod, a pipe, and the like.

According to the diameter of the wire, wire produced by such a wire drawing machine can be classified into fine wire (less than 0.1 mm), median wire (0.5 to 2.5 mm), and wire wire (more than 2.5 mm) With the development of the semiconductor industry and the new drug business, wire manufacturing technology has been greatly developed through the expansion of the wire market and the enhancement of added value.

The wire produced by such a drawing machine is bundled into a bundle of wires by bundling a plurality of wires by a winding machine, and the bundle of wires is cut into a predetermined length and then packaged and supplied to a consumer.

On the other hand, such a cutting operation of the wire has been performed by a cutting device such as a grinder type, a hydraulic type, or a laser type.

The grinder-type cutting apparatus has a problem in that during the cutting of the wire bundles, the wires are tangled and tangled together, or the temperature rises during the cutting process, and the ends of the cut wires are pressed together. In the grinder-type cutting apparatus, scratches are generated on the surfaces of the wires due to friction between the grinder and the wires rotating at high speed, burrs are generated at the cut ends of the wires, and straightness and precision are lowered There is a problem that the quality of the product deteriorates. The laser cutting device has a higher straightness and accuracy than the grinding-type cutting device and the hydraulic-type cutting device. However, when cutting the laser cutting device, the sintering phenomenon occurs similarly to the grinder method.

In order to solve the above problems, Korean Patent Laid-Open Publication No. 10-2013-0060559 discloses a control unit which can be operated from the outside, and a moving unit is formed at a lower portion thereof. A cutting press for cutting the wire in the vertical direction at the rear end of the roller feed part, and a product storage part for holding a plurality of storage spaces for storing the wire cut at the rear end of the cutting press and the product storage part, The wire cutting apparatus according to claim 1,

However, the wire cutting apparatus proposed in the above publication has a problem in that the roller supply unit and the cutting press are independently operated by separate driving sources.

In order to solve the problem of the wire cutting apparatus proposed in the above publication, Korean Patent Registration No. 10-1415964 discloses a wire cutting apparatus capable of continuously cutting a lead wire to a predetermined length continuously while minimizing a cutting tolerance, A possible lead wire cutting device has been proposed.

On the other hand, in the wire cutting apparatus proposed in the above publications, only one end of the wire is clamped and then the wire is cut. Accordingly, when the wire is cut to a long length, there is a problem that the wire tangles.
