Description

Wire supply machine of wire cutting machine

The present invention relates to a wire feeding machine for processing machinery, in particular to a wire feeding machine for wire cutting machines.

In the technical field of general wire cutting machines, the processing principles are divided into slow wire processing and fast wire or medium wire processing. The principles of slow wire processing and fast wire or medium wire processing are similar, but the equipment structure and the use of The consumables are different, and the finished products produced by the two processing principles are completely different.

The wire walking process mainly uses brass wire, tungsten wire or galvanized wire as the electrode wire, and pure water is used as the insulating medium, and the structure of the wire walking machine mainly moves the wire by unidirectional movement. The wire, tungsten wire or galvanized wire will be discarded after the one-way wire is finished once, and when the brass wire, tungsten wire or galvanized wire is processed on the conductive material, the wire diameter of each contact with the conductive material The thickness is the same, which makes it easy to maintain the accuracy after processing within ±0.005 mm, and because the brass wire, tungsten wire or galvanized wire only moves in one direction and does not reciprocate the wire, so the processed conductive material will not The reversing texture produces a very good finish. The disadvantage is that the brass wire, tungsten wire or galvanized wire is discarded only once after one-time use, so the cost of use is very high.

Fast wire or medium wire processing mainly uses molybdenum wire as electrode consumables, and uses emulsion as a cooling and discharge medium. The structure of the fast wire or middle wire processing machine can mainly make the molybdenum wire reciprocate. Processing conductive materials, because the molybdenum wire will move in the reverse direction after the wire is transported in one direction. Since the molybdenum wire can repeatedly process the conductive material, the cost is relatively slow. The wire processing machine is low. However, its molybdenum wire Every time the operation is repeated, there will be wear and tear, resulting in a slight loss of the conductive material after processing, resulting in a change in accuracy of more than ±0.03mm.

Please refer to FIG. 1 and FIG. 2, which is a winding method of a fast wire or middle wire processing machine, which mainly includes a fast wire or middle wire processing machine 10, and the fast wire or middle wire processing machine 10 has a The take-up reel 11 and the plurality of wire wheels 12, one end of the molybdenum wire 20 is fixed on the take-up reel 11 and surrounds each of the wire wheels 12, and finally the other end of the molybdenum wire 20 is fixed on the take-up reel 11, Make the molybdenum wire 20 wrap around the take-up reel 11 and each of the wire wheels 12; please refer to FIG. 2 for a cross-sectional view of winding the molybdenum wire 20 on the take-up reel 11, only one layer of molybdenum wire 20 can be wound on the take-up reel 11 And the molybdenum wire 20 cannot be stacked, because when the retractable reel 11 is rotating, the molybdenum wire 20 on the retractable reel 11 is discharged from one end, and the molybdenum wire 20 is reeled from the other end of the retractable reel 11 Because the reel 11 can not adjust the position of the molybdenum wire 20 in the rewinding process, if two layers of molybdenum wire 20 are stacked, the molybdenum wire 20 of the reel 11 is easily knotted during the processing, and the molybdenum The wire 20 is only wrapped around the take-up reel 11 in a single layer, so that the total length of the molybdenum wire 20 is shorter. The shorter the molybdenum wire 20 must be alternately forward and reverse. And adjust the wire transport direction, not only delay the processing time, each time the molybdenum wire 20 changes the wire transport direction, its overall thickness is consumed by the previous wire transport, which in turn causes errors in the next wire transport processing.

As can be seen from the foregoing, since the general fast-wire or middle-wire processing machine 10 does not have a one-way cable system, it cannot be wound with brass wire, tungsten wire or galvanized wire such as the slow wire processing machine. If the general processing factory must simultaneously To use fast wire or medium wire processing and slow wire processing, you must purchase fast wire or medium wire processing machine and slow wire processing machine at the same time, but the price of fast wire or medium wire processing machine and slow wire processing machine Both are very expensive. If you buy two processing machines at the same time, it will inevitably become a big burden for the processing factory. In view of this, it is really necessary to solve the need to buy fast-thread or medium-wire processing machines 10 and slow-wire processing machines at the same time. In the situation, it is more necessary to solve the problem that the molybdenum wire 20 can only be wound on the take-up reel 11 in a single layer. Because the molybdenum wire 20 is too short, the wire needs to be reversed from time to time, resulting in a delay in processing time and a lack of processing error.

The first object of the present invention is to solve the problem of the lack of communication between the wire winding methods of the fast-wire or middle-wire processing machine and the slow-wire processing machine, thereby solving the problem of excessive cost for users.

The second object of the present invention is to solve the problem that the molybdenum wire of the fast-travel or medium-wire processing machine can only be wound on the reel in a single layer, resulting in the lack of frequent reversing and transporting of the wire, thereby solving the problems of processing delay and processing errors .
