Description

Wire cutting machine for line machine

Technical field

The utility model relates to processing equipments for line machine, especially with regard to a kind of wire cutting machine for line machine.

Background technique

In the technical field of general wire electrode cutting machine, process principle is divided into slow wire feeding processing and fast wire winding or middle wire Processing, slow wire feeding processing and fast wire winding or the principle of middle wire processing are close, and only device structure and the consumptive material used are different, And the finished product for generating two kinds of process principles is not completely identical.

Slow wire feeding processing mainly uses brass wire, tungsten wire or galvanized wire as wire electrode, and using pure water as dielectric, And the structure of slow wire feeding processing machine is mainly by the mode wire transporting of one-way movement, since brass wire, tungsten wire or galvanized wire are unidirectional After wire transporting is primary, i.e., can be discarded, and brass wire, tungsten wire or galvanized wire to conductive material process when, every time with lead Electric material contact line footpath thickness it is all the same, make its process after precision be easily retained within ± 0.005 mm, more because Only one-way movement is without reciprocal wire transporting for brass wire, tungsten wire or galvanized wire, therefore the conductive material after processing will not generate commutation Lines and make finish very good, disadvantage be then because brass wire, tungsten wire or galvanized wire are only unidirectionally using once abandoning, because This use cost is very high.

Fast wire winding or middle wire processing use emulsion as cooling and electric discharge mainly using molybdenum filament as electrode consumptive material The structure of medium, fast wire winding or middle wire processing machine can mainly allow molybdenum filament to move back and forth, and process by molybdenum filament reciprocating motion Conductive material, since molybdenum filament is after unidirectional wire transporting is primary, can again towards reversed wire transporting actuation, due to molybdenum filament can repeatedly actuation to leading Electric material processing, therefore cost is low with respect to slow wire feeding processing machine, however, its molybdenum filament can all generate consumption in actuation repeatedly every time Damage causes conductive material after processing can be because consume causes precision in the variation of ± 0.03mm or more slightly.

Fig. 1 and Fig. 2 is please referred to, is the winding mode of fast wire winding or middle wire processing machine, mainly includes a fast wire winding Or middle wire processing machine 10, and there is a folding and unfolding line wheel 11 and multiple guide rollers 12 on the fast wire winding or middle wire processing machine 10, Wherein one end of molybdenum filament 20 is fixed in the folding and unfolding line wheel 11 and around the respectively guide roller 12, and the other end of last molybdenum filament 20 is solid again Due to being surrounded on the molybdenum filament 20 in the folding and unfolding line wheel 11 and the respectively guide roller 12；Fig. 2 is please referred to receive The cross-sectional view of molybdenum filament 20 is wound on actinobacillus wheel 11, one layer of molybdenum filament 20 of winding is only capable of in the folding and unfolding line wheel 11, and cannot make molybdenum filament 20 Xiang Die, since the folding and unfolding line wheel 11 is in rotation, the molybdenum filament 20 in the folding and unfolding line wheel 11 is released from wherein one end, and molybdenum filament 20 From the other end winding displacement of folding and unfolding line wheel 11, winding displacement of the molybdenum filament 20 during folding and unfolding can not be adjusted due to folding and unfolding line wheel 11 and voluntarily Position, the molybdenum filament 20 of folding and unfolding line wheel 11 is easy to knot in process if two layers of the molybdenum filament 20 that mutually change, and the only single layer of molybdenum filament 20 It is wound in folding and unfolding line wheel 11, so that the total length of molybdenum filament 20 is shorter, shorter molybdenum filament 20 then often forward and reverse must alternately be transported Silk, however the every steering of molybdenum filament 20 once requires Suspend Job and adjusts wire transporting direction, not only postpones process time, each molybdenum filament 20 when changing a wire transporting direction, and whole thickness produces wire transporting processing next time all because a preceding wire transporting is consumed Raw error.

From the foregoing, it can be seen that due to general fast wire winding or the not unidirectional Cable Assembly system of middle wire processing machine 10, therefore can not twine Around such as brass wire of slow wire feeding processing machine, tungsten wire or galvanized wire, if general processing factory must use fast wire winding or middle wire simultaneously Processing and slow wire feeding processing, then must buy fast wire winding or middle wire processing machine and slow wire feeding processing machine simultaneously, however fast wire winding Or the price of middle wire processing machine and slow wire feeding processing machine is all very expensive, if buying two kinds of processing machines simultaneously, certainly will become plus The big burden of the one of work factory, in view of this, it is necessory to solve that fast wire winding or middle wire processing machine 10 need to be bought simultaneously and be careful Silk processing machine causes the case where greatly bearing, and more it is necessary to solve molybdenum filament 20 to be only capable of winding of single layer in folding and unfolding line wheel 11, because of molybdenum Silk 20 is too short to lead to the wire transporting that must commutate often, and generates process time delay and generate the missing of mismachining tolerance.
