Description
Technical field
The utility model relates to a kind of fine electric spark punch.
Background technology
Punch also is the pore Electrical Discharge Machine, and its operation principle is to utilize the moving thin metal copper pipe (being called wire electrode) that moves both vertically up and down continuously to make electrode, and workpiece is carried out pulse spark discharge generation high temperature corrosion metal forming.Electrode and intermetallic discharge generation high temperature corrosion metal reach the purpose of perforation.Its wire electrode of existing punch generally is installed on the swivel head, swivel head drives it by belt and moves both vertically up and down, but often there is the larger problem of vibration in belt, so that the machining accuracy of product is received impact, and the electric current on the existing punch wire electrode is larger, also so that the machining accuracy of product is not high.
Summary of the invention
For solving the existing low problem of punch machining accuracy in the background technology, the utility model provides a kind of fine electric spark punch.
The technical solution of the utility model is: a kind of fine electric spark punch, comprise housing, workbench, swivel head, input module, change-over switch and rectistack, the output of described change-over switch is connected with the input of rectistack, described housing comprises dust cover, be provided with servomotor in the described dust cover and by the leading screw of driven by servomotor, swivel head is fixed on the leading screw by the feed screw nut fixed mount; Described rectistack links to each other with the input of control module, and described control module is provided with the vernier control circuit; The output of described control module is connected respectively with for the servomotor input of leading screw control, the processing module of processing for product.
As a kind of improvement of the present utility model, described input module for the voltage input is connected with change-over switch by transformer.
As another kind of improvement the of the present utility model, the chip that described control module adopts is 4051.
The beneficial effects of the utility model are that servomotor makes steadily adjustable moving both vertically up and down of swivel head by leading screw, has guaranteed that pore adds the machining accuracy in man-hour.Simultaneously by increasing the vernier control circuit, so that the electric current of control module output is less, adds and man-hour the single electric current in hole is diminished, guaranteed the precision of pore processing.

The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
By Fig. 1 in conjunction with shown in Fig. 2,3,4, a kind of fine electric spark punch, comprise housing, workbench 1, swivel head 5, input module, change-over switch and rectistack, described housing comprises dust cover 2, the leading screw 4 that is provided with servomotor 3 in the described dust cover 2 and is driven by servomotor 3, swivel head 5 is fixed on the leading screw 4 by feed screw nut fixed mount 6.
Described input module for the voltage input is connected with change-over switch by transformer, and the setting of transformer can be so that the user inputs high, medium and low voltage signal according to different situations.
The output of described change-over switch is connected with the input of rectistack, and described rectistack is rectifier, and its model is 6RI50E-080.Described rectistack links to each other with the input of control module, and described control module is provided with the vernier control circuit; The vernier control circuit can according to the current value that is input to the automatic regulation output end of the magnitude of current on the control module, guarantee that the electric current of output is steady.
The output of described control module is connected respectively with for the servomotor input of leading screw control, the processing module of processing for product, described processing module adds the feedback signal that produces man-hour and feeds back to control module, by the action of control module control servomotor, the model of the control chip of described control module is 4051.
The beneficial effects of the utility model are that servomotor makes steadily adjustable moving both vertically up and down of swivel head by leading screw, has guaranteed that pore adds the machining accuracy in man-hour.By increasing the vernier control circuit, so that the electric current of control module output is less, the single electric current for the treatment of machining hole diminishes simultaneously, has guaranteed the precision of pore processing.
The utility model is adding man-hour, can input different voltage signals to system according to client's different situations, after the change-over switch conversion, by rectistack to the control module input current signal, difference according to input current signal is exported to processing module, treat the processing metal surface and carry out the pulse spark discharge, make the high temperature corrosion metal of generation, form through hole.Since added the vernier control circuit, less through every part of pulse current of control module output, avoided in the past once large electric current to the destruction of metal surface, so that pore diameter to be processed becomes large problem, thereby guaranteed machining accuracy and the crudy of pore.Simultaneously when meeting metal to be processed somewhere when really up to the mark, signal according to the processing module feedback, control module is sent signal, carry on servomotor control swivel head is temporary transient, and then swivel head is descended, metal is crossed hard portion realize repeatedly little electrolytic corrosion, guarantee the processing of pore, and the safety of equipment.
Every technical staff's notice: although the utility model describes according to the above-mentioned specific embodiment; but invention thought of the present utility model is not limited in this utility model; the repacking of any utilization inventive concept all will be included in this patent scope of patent protection.
