Background
At present, wire cut electrical discharge machining is rapidly developed in special machining, is widely applied to industrial production and plays an important role in dies, precision parts, special materials and micro-machining, but the mainstream wire cut electrical discharge machining machine carries out machining under the condition that a workpiece is drilled with a hole. This directly increases the processing cost and processing time. The invention is based on the idea of modularization, combines the electric spark perforating machine and the electric spark wire cutting machine, and facilitates the conversion of processing modes by modularly designing the perforating machine.
Disclosure of Invention
An electric spark wire cutting device capable of carrying out online punching comprises a machine body, a punching module, a guide frame, a suspension arm and the like. The punching tool electrode is fixed on the electrode clamping head through the adjusting screw to form an integral module, the integral module is connected with the connector through the screw, the connector is connected with the upper support through the screw, the support is provided with the through hole through which the electrode wire can pass, and the wire penetrating is carried out after the tool electrode is dismounted, so that the wire penetrating is carried out on the next step of wire cutting processing.
The wire electric discharge machine capable of performing online punching according to claim 1, characterized in that: after the punching processing is finished, the workpiece can be continuously subjected to linear cutting processing under the condition that the workpiece position does not move by rapidly disassembling the punching module.
The invention has the advantages that: because the secondary clamping is not needed, the positioning precision of the workpiece can be ensured, the punching module is of a detachable structure, the assembly and disassembly are convenient, the processing steps are simple, efficient and easy to implement, the processing efficiency can be improved to the maximum extent, and the processing precision of the workpiece is improved.

The invention is further described below with reference to the accompanying drawings.
FIG. 1 is a schematic diagram of the on-line punching operation of the present invention.
Fig. 2 is a schematic view of the wire cutting operation of the present invention.
Fig. 3 is a punching module of the present invention.
In the figure: 1-base, 2-workbench, 3-tool electrode, 4-electrode clamping head, 5-connector, 6-fixing frame, 7-bearing, 8-rolling pulley, 9-overhanging arm, 10-guide frame, 11-wire electrode, 12-adjusting screw.
Detailed Description
The utility model provides a spark-erosion wire cutting device that can punch on line, the device includes fuselage, the module that punches, wire-electrode cutting module, leading truck, cantilever arm etc. its characterized in that: the processingequipment the module of punching on line has, the module of punching fix on electrode holding head 4 and be connected through set screw with connector 5 and constitute by instrument electrode 3 through adjusting screw 12, connector 5 pass through the fix with screw on mount 6, the mount link to each other with overhanging arm 9, 9 one side of mount have the dovetail structure card and can follow the dovetail and reciprocate on the guide holder 10 that also has the dovetail structure, other side rolling pulley 8 and bearing 7, pulley 8's effect is dredged electrode wire 11 and is passed through the guide wire hole on the mount of below. The guide frame 10 is fixed to the table 2, thus completing the installation of the main part of the device of the invention.
The electrode clamping head 4, the connector 5 and the fixing frame 6 are provided with passages through which electrode wires can pass, so that the tool electrode can be taken down only to thread the electrode wires, and the next step of electrospark wire-electrode cutting machining can be completed.

Claims (4)

1. An electric spark wire cutting device capable of carrying out online punching comprises a machine body, a punching module, a guide frame, a suspension arm and the like.
2. The method is characterized in that: the punching tool electrode is fixed on the electrode clamping head through the adjusting screw to form a whole, the whole is connected with the connector through the screw, the connector is connected with the upper support through the screw, the through hole is formed in the support and can be used for the electrode wire to pass through, and therefore the wire can be threaded after the tool electrode is detached to perform linear cutting machining on the next step.
3. The wire electric discharge machine capable of performing online punching according to claim 1, characterized in that: after the workpiece is punched, the punching module can be rapidly detached, after the wire threading work is finished, the wire cutting machining is continuously carried out under the condition that the position of the workpiece does not move, and thus the reduction of the precision caused by secondary clamping can be avoided.
4. The wire electric discharge machine capable of performing online punching according to claim 1, characterized in that: the suspension arm can move up and down on the guide frame through the driving of the motor, so that the online punching of the workpiece is completed.
