Description
Technical field
The utility model relates to a kind of electric spark linear cutting machine, particularly a kind of electricity-supply device that is used for electric spark linear cutting machine.
Background technology
Electricity-supply device is important spare part in the fast wire electrical discharge machine tool, its effect is to make the wire electrode of high-speed cruising and electricity-supplying piece excellent contact and form negative pole in the processing, processing parts is as the positive pole of the pulse power, under the control of computer, thereby reach the purpose of corroding metal by pulsed discharge.Electricity-supply device mainly is made of electricity-supplying piece, electricity-supply seat and collets, and electricity-supplying piece is installed on the electricity-supply seat, and electricity-supply seat is installed on the collets.
In existing electricity-supply device, electricity-supplying piece adopts circular block structure, is installed in the endoporus at copper frame center, and two ends are fixed with holding screw, and whole then parts are installed on the electricity-supply seat.In use, wire electrode is pressing circular electricity-supplying piece, makes wire electrode become negative pole.Wire electrode can constantly hurt circular electricity-supplying piece in the high-speed motion process, therefore circular electricity-supplying piece can rotate use together with the copper frame on electricity-supply seat, to avoid card outage polar filament.Although circular electricity-supplying piece can be by rotation change use location, but along with the line cutting processing is constantly carried out, cut channel on the circular electricity-supplying piece is more and more, change the arbitrarily angled cut channel that formerly forms all can't avoided fully, this will influence discharge effect and badly influence, at last may the wire electrode card is disconnected, therefore need often to change electricity-supplying piece, be unfavorable for reducing production costs.
The utility model content
Technical problem to be solved in the utility model provides a kind of electric spark linear cutting machine electricity-supply device, and it is disconnected to avoid wire electrode to be blocked effectively, improves the crudy of wire cutting machine tool, and the service life of improving electricity-supplying piece significantly.
The technical scheme that its technical problem that solves the utility model adopts is: electric spark linear cutting machine electricity-supply device of the present utility model, comprise electricity-supply seat, electricity-supplying piece and collets, it is characterized in that: described electricity-supplying piece is a rectangular block, offer the slippage groove suitable with the electricity-supplying piece width on electricity-supply seat, holding screw is fixed on electricity-supplying piece in the slippage groove on the electricity-supply seat by being installed in.
As a kind of preferred version of the present utility model, for farthest improving the service life of electricity-supplying piece, the width of described electricity-supplying piece equates with thickness.
The beneficial effects of the utility model are, the rectangle electricity-supplying piece can change contact position with wire electrode by the slippage in the slippage groove on its total length direction, and the use of electricity-supplying piece turnable, therefore the service life that can improve electricity-supplying piece significantly, help reducing production costs; Can avoid the cut channel that formerly forms behind the change of location fully, it is disconnected therefore can to avoid wire electrode to be blocked effectively, and improves the crudy of wire cutting machine tool, can guarantee all the time that the surface roughness value of processing parts reaches Ra≤2.5 μ m.
Description of drawings
This specification comprises following three width of cloth accompanying drawings:
Fig. 1 is the structural representation of the utility model electric spark linear cutting machine electricity-supply device;
Fig. 2 is an electricity-supplying piece front view in the utility model electric spark linear cutting machine electricity-supply device;
Fig. 3 is the structural representation of electricity-supply seat in the utility model electric spark linear cutting machine electricity-supply device.
Parts shown in the figure, toponym and pairing mark: electricity-supply seat 10, slippage groove 11, holding screw 12, attachment screw 13, electricity-supplying piece 20, collets 30.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, electric spark linear cutting machine electricity-supply device of the present utility model comprises electricity-supply seat 10, electricity-supplying piece 20 and collets 30.See figures.1.and.2, described electricity-supplying piece 20 is a rectangular block.With reference to Fig. 3, on electricity-supply seat 10, offer and the suitable slippage groove 11 of electricity-supplying piece 20 width.With reference to Fig. 1, holding screw 12 is fixed on electricity-supplying piece 20 in the slippage groove 11 on the electricity-supply seat 10 by being installed in.Rectangle electricity-supplying piece 20 can change contact position with wire electrode by the slippage in slippage groove 11 on its total length direction, and electricity-supplying piece turnable 20 uses, and therefore the service life that can improve electricity-supplying piece 20 significantly, helps reducing production costs.And can avoid the cut channel that formerly forms behind the change of location fully, it is disconnected therefore to avoid wire electrode to be blocked effectively, and improves the crudy of wire cutting machine tool, can guarantee all the time that the surface roughness value of processing parts reaches Ra≤2.5 μ m.
See figures.1.and.2, for farthest improving the service life of electricity-supplying piece 20, the width of described electricity-supplying piece 20 equates that with thickness promptly four of electricity-supplying piece 20 equal turnables of outer surface use.Fig. 1 shows a kind of typical mounting means of electricity-supply seat 10 simultaneously, and promptly described electricity-supply seat 10 is installed in collets 30 on by two attachment screws 13 of laying thereon at interval at least.
Some principles of the above the utility model electric spark linear cutting machine electricity-supply device that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
