Description

A kind of WEDM

Technical field

The utility model relates to metal material processing equipment, especially referring to the processing (precision prescribed height, long processing time, surface smoothness special requirement) to thick and heavy big workpiece, must be the WEDM (Electric Discharge Wire-cut Machine) of wire electrode by alloys such as molybdenum or copper.

Background technology

Existing WEDM comprises that upward planker (Y direction moves), wire storage cylinder, column reach coil holder group and tapering header structure up and down for lathe bed pedestal, following planker (X-direction moves), wherein: the coil holder group was fixed about wire storage cylinder reached, with processed metal works, be positioned on the folded mutually planker of two intersections, be on the mobile planker of mobile following planker of left and right directions (X-axis) and fore-and-aft direction (Y-axis), do moving of different directions respectively.Because planker itself is subject to requirements such as rigidity intensity, certain area and thickness must be arranged, deadweight has at least also just been arranged.When mobile, the weight of planker itself adds the weight of big workpiece, must start with bigger horsepower and pass.Again according to the effect of inertia on the physics, start when mobile so, desire is static as the same in the motion, requires high accuracy control when displacement is with frequent commutation at a high speed more difficult.In addition, when the bigger workpiece of thickness add man-hour often deslagging often be not easy, also need simultaneously big electric current, this moment as adopt soaking type processing, water filling soaks that completely to reach draining be again a difficulty during operation, can not realize the most basic processing request with present domestic existing mechanical structure, and international existing completely different of a structure and fast wire structure of being careful, not only the manufacturing cost height does not have wire storage cylinder again, transport the mode difference of silk, can not be used for the WEDM of quick wire.

The utility model content

In view of existing WEDM does not reach the requirement of thick and heavy big workpiece Precision Machining, the applicant provides a kind of quick wire and slow two kinds of methods of operation of formula wire, water spray and spendable WEDM of immersion mode of having concurrently.

A kind of WEDM provided by the utility model, comprise the lathe bed pedestal, down planker, go up planker, wire storage cylinder device, column and composite set, the tapering header structure of coil holder up and down, it is characterized in that: the first half of described lathe bed pedestal is processed into the platform of place work piece, and the left side is equipped with the following planker that can relatively move with it; On following planker, be equipped with can relatively move with it on planker, wire storage cylinder device and column and the composite set of coil holder up and down are installed above the planker on this.

In above-mentioned WEDM, platform is provided with as immersion or water spray and adds water storage or the tank used of dash in man-hour.

In above-mentioned WEDM, the mode that following planker is installed on the described lathe bed pedestal is: the screw mandrel and the line slideway of X axis are installed above the described lathe bed pedestal, and described planker down flexibly connects thereon with slide block and nut sleeve form.

In above-mentioned WEDM, the mode that last planker is installed on the described down planker is: described install above the planker down Y-axis to screw mandrel and line slideway, the described planker of going up flexibly connects thereon with slide block and nut sleeve form.

In above-mentioned WEDM, the wire storage cylinder device is placed in the left side of planker, except can positive and negative rotation, be mutually vertical 90 ° displacement with following planker on last planker, to keep the position of center line of wire at upper and lower coil holder.

In above-mentioned WEDM, the column vertical fixing is in last planker right side, coil holder in the support, and the device of Z axial adjustment height is arranged, to cooperate the thickness of work piece; Following coil holder also is fixed in planker, hangs down as for the column of supporting to go up coil holder, and parallel with last coil holder.

Owing to adopted above-mentioned technical solution, a kind of quick wire and slow two kinds of methods of operation of formula wire, water spray and all spendable WEDM of immersion mode of having concurrently promptly be provided.

Description of drawings

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is a side view of the present utility model.

The specific embodiment

Shown in Fig. 1～3, whole machinery of the utility model is by six most of compositions: lathe bed pedestal 1, down planker (X-axis) 2, go up planker (Y-axis) 3, wire storage cylinder 4, column and about composite set 5, the tapering header structure (U, V axle) 6 of coil holder.

1) lathe bed pedestal 1 is whole the member that machinery is maximum, is formed by a foundry goods, and first half is processed into the platform 7 of place work piece, can add the tank (not shown) and add man-hour as immersion or water spray, and water storage or dash are used.Because lathe bed pedestal 1 is motionless, platform 7 does not just have displacement yet, can place the workpiece also heavier than lathe bed, and center of gravity is low, steady, and it is its great advantage easily that workpiece is placed up and down.Left side processing is also installed the screw mandrel and the line slideway 81 of X axis, to support down planker 2 and to do the displacement of left and right directions (X).

2) down planker 2 forms relative motion to pedestal with slide block and nut sleeve (not shown), the screw mandrel and the line slideway 82 of Y direction is installed again, to carry planker 3 above it.

3) go up planker 3 bottom surfaces and still form to front and back (Y) axial displacement of planker 2 down installation wire storage cylinder device 4 and column 51 and the composite set 5 of

coil holder

52,53 above up and down with slide block and nut sleeve (not shown).When following plankers 2 displacements of 3 pairs of last plankers, also equal Y to the lathe bed pedestal to displacement, and same also passive and then down the displacement of planker 2 and to the X of lathe bed pedestal 1 to displacement.

4) wire storage cylinder 4 is a unique apparatus, is placed in the left side of planker 3, except can positive and negative rotation, still can be mutually vertical 90 ° displacement with following planker 2 on last planker 3, keeps the position of center line of wire at upper and lower coil holder 52,53.Wire does not have wire storage cylinder at a slow speed, but can install the receipts metal wire structure.

5) column 51 vertical fixing are in last planker 3 right sides, and coil holder 52 in the support, and the device of Z axial adjustment height is arranged, to cooperate the thickness of work piece.Following coil holder 53 also is fixed in planker 3, hangs down as for the column 51 of supporting to go up coil holder 3, and parallel with last coil holder 52.

The tapering header structure can adopt the acquired patent of the applicant (patent No.: ZL200420022893.1), be installed in coil holder foremost as the device of U, V axle cutting tapering, axially displaced with respect to (U) front and back (V) about last coil holder.

Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong within the category of the present utility model, should be limited by each claim.And include within the scope of claim.
