Abstract

The combined double-head linear cutting machine includes machine bed, guide rails, X-Y trailing bar and cutting head including mainly line barrel, machining electrode filament and upright line holder. On the same guide rail pair, there are two X-Y trailing bars with separate cutting head, and the bench with workpiece to be cut is fixed onto the machine bed. This kind of combined double-head linear cutting machine has increased work stroke, and thus can machine large workpiece and has doubled linear cutting function and doubled cutting efficiency.

Description

Combined type double end wire cutting machine tool

Technical field

The present invention relates to a kind of wire cutting machine tool, particularly a kind of combined type double end wire cutting machine tool.

Technical background

Existing wire cutting machine tool all is made up of a cover numerical control electrical equipment, lathe bed, silk tube, column guide frame and a secondary X-Y axis carriage etc., be cut workpiece clamp and be contained on the workbench on the X-Y axis carriage, the workpiece that is cut that is driven on the planker by numerical control program control moves by track; And the machined electrode molybdenum filament on silk tube and the column guide frame is fixed on definite operating position and does the linear speed motion, forms the machined electrode molybdenum filament and is cut the relative motion of workpiece, thereby reach the purpose of cutting.But this structure is owing to be cut workpiece and be fixed on the X-Y axis carriage, and the ability that makes it to carry workpiece is restricted, and when overweight, the stepper motor moment that the X-Y axis carriage can occur driving causes step-out inadequately; In addition, be subjected to the influence of stroke limitation, particularly process workpiece such as big mould, it is very low that working (machining) efficiency just shows, and process time can be very long, so every lathe, the scope that its processing is used just seems very little; In order to satisfy the needs of different big or small work pieces, the general user often needs to buy the wire cutting machine tool of a lot of various models, so just causes equipment to use site area to increase, and investment repeats, defectives such as feature of environmental protection difference.

Summary of the invention

The objective of the invention is to provide that a kind of working (machining) efficiency height, the processing scope of application are big for the deficiency that solves above-mentioned technology, lathe low cost of manufacture and reduce the combined type double end wire cutting machine tool of floor space.

In order to achieve the above object, a kind of combined type double end wire cutting machine tool that the present invention is designed, it comprises lathe bed, guide rail, X-Y axis carriage and mainly comprises the cutting head of silk tube, machined electrode silk and column coil holder, be provided with the X-Y axis carriage that two pairs respectively carry cutting head on the same secondary guide rail of lathe bed.Fixedly connected with lathe bed to being cut the bearing capacity of workpiece, clamping the workbench that is cut workpiece in order to improve lathe.In order to guarantee that two cover cutting heads can realize cutting function as required separately separately, on the Y-axis planker of two secondary X-Y axis carriages, be provided with separately and drive the screw mandrel of Y-axis planker at the guide rail top offset.

The resulting a kind of combined type double end wire cutting machine tool of the present invention, owing on a secondary guide rail of a big lathe bed, realize two cover X-Y axis carriages, and what load on the X-Y axis carriage is the cutting head of little load, made it to strengthen the impulse stroke of former ordinary lines cutting off machine, the workpiece of energy machining large wire cutting machine tool, and, can be used as the logical wire cutting machine tool of two Daeporis again uses, possesses the line cutting function that the logical wire cutting machine tool of two Daeporis works independently simultaneously, make it under equal occupation of land situation, than the large-scale wire cutting machine tool efficient raising 100% of original common single cutting head; Under equal process velocity, the equipment occupation of land reduces half, thereby has reduced the pollution of equipment to environmental protection, has improved the feature of environmental protection; In addition, because the load of work piece directly is carried on the lathe bed, for the stepper motor that drives the X-Y axis carriage, the load of its carrying will not be influenced by the weight of work piece will, thereby improved the bearing capacity of the big die workpiece of machine tooling, guaranteed the cutting processing precision of excess weight workpiece; When increasing work efficiency and reducing floor space, it has reduced the manufacturing cost of equipment again, saves manufactured materials, has also reduced the energy consumption when using under the condition of the identical cutting member of processing; It has very real positive effect to the development of wire cutting machine tool.

The specific embodiment

The invention will be further described in conjunction with the accompanying drawings below by embodiment, but following embodiment does not limit content of the present invention.

Embodiment 1

As Fig. 1, Fig. 2, shown in Figure 3, a kind of combined type double end wire cutting machine tool that present embodiment is described, it comprises lathe bed 1, guide rail 2, X-Y axis carriage 34 and mainly comprise silk tube 5, the cutting head 11 of machined electrode silk 7 and column coil holder 8, on the same secondary guide rail 2 of lathe bed 1, be provided with the X-Y axis carriage 34 that two pairs respectively carry cutting head 11, cutting head 11 is fixing with the X-axis planker 3 in the X-Y axis carriage 34, clamping the workbench 6 that is cut workpiece 10 fixedlys connected with lathe bed 1, be provided with separately on the Y-axis planker 4 of two secondary X-Y axis carriages 34 and drive the screw mandrel 12 of Y-axis planker 4 at guide rail 2 top offsets, Y-axis planker 4 can roll by ball 9 with 2 on guide rail and cooperate.

A kind of combined type double end wire cutting machine tool that present embodiment obtains, during work, two cover cutting heads 11 are on same guide rail 2, along with moving of the X-Y axis carriage of being controlled by numerical control 34, can be opposite on the stationary work-table 6 same is cut workpiece 10 and carries out cutting processing, again can be on demand to the different independent cutting processing of workpiece that are cut, thereby be implemented on the wire cutting machine tool, can the workpiece that be cut of all size specification be carried out the line cutting processing, improve working (machining) efficiency and machining accuracy.
