Description

Technical Field

[0001] The utility model relates to an electric spark wire cutting device. Background Art

[0002] Electrospark machining is a process that uses pulsed spark discharge to erode the material being machined. There is no contact between the machining electrode and the material being machined due to the presence of a liquid dielectric, so a softer electrode (tool) can be used to machine hard and brittle conductors such as metals and semiconductor materials.

[0003] The most widely used EDM process is the moving wire electrode cutting process. The cutting wire used in wire electrode cutting is the electrode wire (metal wire). In the current equipment, the electrode wire is wound on the drum, and before the electrode wire is wound on the drum, it needs to be "drawn". "Wire drawing" means that the electrode wire that has been "threaded" is pulled to the side of the drum. "Wire drawing" needs to be manually operated by workers. There is no special wire drawing mechanism, which is time-consuming and labor-intensive, with high labor costs, and the wire drawing effect cannot be guaranteed, and the efficiency is low. Summary of the invention

[0004] The technical problem to be solved by the utility model is that the existing electric spark wire cutting equipment does not have a special wire drawing mechanism and relies entirely on manual wire drawing, which is time-consuming and labor-intensive, has high labor costs, cannot guarantee the wire drawing effect, and has low efficiency.

[0006] The wire drawing clamp cylinder is connected to the wire drawing clamp and can control the opening and closing of the wire drawing clamp.

[0007] The above technical solution is further limited in that it also includes a left wire drawing fixing seat, a right wire drawing fixing seat installed and fixed on the right side of the left wire drawing fixing seat, and a clamping seat mounting seat;

[0008] The linear guide rail is installed and fixed on the left wire drawing fixing seat and the right wire drawing fixing seat;

[0009] The clamping seat mounting seat is mounted and fixed on the guide rail slider;

[0010] The wire drawing clamp seat is installed and fixed on the clamp seat mounting seat.

[0011] A further limitation of the above technical solution is that the wire drawing clamp includes two clamping pieces that can be opened and closed, and the wire drawing clamp cylinder can control the opening and closing of the two clamping pieces of the wire drawing clamp.

[0012] A further limitation of the above technical solution is that it also includes a clamp seat cover plate, which is fixedly mounted on the top of the wire drawing clamp seat and covers the wire drawing clamp and the wire drawing clamp cylinder.

[0013] The above technical solution is further limited in that it also includes a motor bracket, a wire drawing motor, a wire drawing driving wheel, a driven wheel mounting plate, a wire drawing driven wheel and a wire drawing synchronous belt;
