Description

Technical Field

[0001] This invention belongs to the field of wire EDM wire disassembly technology, and particularly relates to a wire EDM metal wire disassembly tool. Background Technology

[0002] Wire EDM is a metal cutting method that uses the principle of electrical discharge to cut metal. It typically uses a thin metal wire (such as molybdenum, copper, or alloy wire) as the electrode wire. Under the action of a pulsed power supply, a spark discharge is generated between the electrode wire and the workpiece, producing high temperatures that melt or vaporize the metal, creating a gap and thus cutting out the desired part. Replacing the wire in a wire EDM requires disassembling the old wire. Since the wire is wound around the rollers of the equipment and is approximately 300 meters long, each replacement requires manual pulling, which is inefficient and can easily cause cuts. Summary of the Invention

[0003] This invention provides a wire cutting wire disassembly tool to overcome the shortcomings of the prior art.

[0004] The technical solution adopted in this invention is as follows: a wire cutting metal wire disassembly fixture, including a wire winding drum and a motor. The wire winding drum includes a left shaft and a right shaft. The inner end of the left shaft has a flange one coaxially, and the inner end of the right shaft has a flange two coaxially. Several wire winding rods and a wire unloading rod are arranged circumferentially between flange one and flange two. The left end of the wire winding rod is fixedly connected to flange one, and the right end is detachably connected to flange two. The two ends of the wire unloading rod are detachably connected to flange one and flange two, respectively. A fastening screw is radially arranged on the wire unloading rod, and the fastening screw is located near the left shaft end. The left shaft and the right shaft are rotatably mounted on the top of a support. An electromagnetic base is fixed at the bottom of the support. The motor is fixed on the support and driven by the left shaft to rotate the wire winding drum.

[0005] The left end of the winding rod is threadedly connected to the threaded hole on flange one. The left end of the unloading rod passes through the through hole on flange one and is threadedly connected to the unloading rod by a nut, thus fixing the left end of the unloading rod to flange one. The right ends of both the winding rod and the unloading rod are inserted into the through holes on flange two. The through hole is composed of a first circular hole and a first strip hole that passes through it, and the first strip hole is located inside the first circular hole and is arranged radially; the left end of the unloading rod has an external thread section and a positioning section with a rectangular cross section, the width of the first strip hole is smaller than the length of the rectangular cross section and the diameter of the first circular hole, and the width of the rectangular cross section is smaller than the width of the first strip hole; the positioning section with the rectangular cross section is inserted into the first circular hole and the length direction of the rectangular cross section is perpendicular to the first strip hole, so that the left end of the unloading rod does not slide into the first strip hole.

[0006] It also includes a guide plate, which has second circular holes evenly distributed around the circumference and second strip holes arranged radially. The guide plate is fitted onto the winding screw through the second circular holes and onto the unloading screw through the second strip holes, and can move axially along the winding screw and the unloading screw.

[0007] The motor is fixed on a support near the left end of the shaft, and the motor is connected to the left shaft via a belt drive mechanism.

[0008] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention enables the rapid disassembly and automated collection of old metal wires from the equipment rollers, improving the replacement efficiency of wire cutting wires and avoiding cuts caused by manual pulling.

[0009] 2. This invention enables the rapid removal of old metal wire from the winding drum by setting a wire unloading rod.

[0010] 3. This invention uses a magnetic base to adhere to the wire cutting equipment, making it easy to install and move, and suitable for disassembling old metal wires from different wire cutting equipment. Attached Figure Description

The inner end of the left shaft 1-1 has a flange 1-1-1 coaxially, and the inner end of the right shaft 1-2 has a flange 1-2-1 coaxially. A plurality of wire winding rods 1-3 and a wire unloading rod 1-4 are arranged circumferentially between the flange 1-1-1 and the flange 1-2-1. The left end of the wire winding rod 1-3 is fixedly connected to the flange 1-1-1, and the right end is fixedly connected to the flange 1-2-1. The unloading rod 1-4 is detachably connected to flange 1-1-1 and flange 2-2-1 at both ends. A fastening screw 1-5 is radially arranged on the unloading rod 1-4, and the fastening screw 1-5 is located near the end of the left shaft 1-1. The left shaft 1-1 and right shaft 1-2 are rotatably mounted on the top of the support 3. An electromagnetic base 4 is fixed at the bottom of the support 3. The motor 2 is fixed on the support 3 and driven by the left shaft 1-1 to drive the winding drum 1 to rotate.

[0014] In one embodiment, the left end of the winding rod 1-3 is threadedly connected to the threaded hole 1-1-2 on flange 1-1-1, and the left end of the unloading rod 1-4 passes through the through hole 1-1-3 on flange 1-1-1 and is threadedly connected to the unloading rod 1-4 by a nut 6, thus fixing the left end of the unloading rod 1-4 to flange 1-1-1; the right ends of the winding rod 1-3 and the unloading rod 1-4 are both inserted into the through hole 1-2-2 on flange 2-1; the through hole 1-1-3 is composed of a first round hole 1-1-5 and a first strip hole 1-1-4 that passes through it, and the first strip hole 1... -1-4 is located inside the first circular hole 1-1-5 and is arranged radially; the left end of the unloading rod 1-4 has an external thread section 1-4-1 and a rectangular cross-section positioning section 1-4-2. The width of the first strip hole 1-1-4 is smaller than the length of the rectangular cross-section and the diameter of the first circular hole 1-1-5. The width of the rectangular cross-section is smaller than the width of the first strip hole 1-1-4. The positioning section 1-4-2 is inserted into the first circular hole 1-1-5 and the length direction of the rectangular cross-section is perpendicular to the first strip hole 1-1-4, so that the left end of the unloading rod 1-4 does not slide into the first strip hole 1-1-4.

[0015] In one embodiment, to facilitate the reinstallation of the winding screw, the unloading screw, and the flange, a guide plate 5 is also included. The guide plate 5 has second circular holes 5-1 evenly distributed circumferentially and second strip holes 5-2 radially. The guide plate 5 is fitted onto the winding screw 1-3 through the second circular holes 5-1 and onto the unloading screw 1-4 through the second strip holes 5-2, and can move axially along the winding screw 1-3 and the unloading screw 1-4.

[0017] In use, first attach the above-mentioned fixture to the worktable of the wire cutting equipment using the magnetic base 4. Then, wrap the end of the old metal wire around the screw 1-5 of the wire unloading rod 1-4 and tighten the screw to fix the old metal wire onto the wire unloading rod 1-4. Then, start the motor 2, which drives the winding drum 1 to rotate, winding the old metal wire on the wire cutting equipment drum onto the winding drum 1. After winding, turn off the motor 2 and the right electromagnetic base 4. Then, move the right electromagnetic base 4, the right shaft 1-2, and the support 3 to the right along the worktable of the wire cutting equipment, so that the wire unloading rod 1-4 and the winding rod 1-3 are pulled out from the through hole 1-2-2 of the flange 2 1-2-1. Separate from the right shaft 1-2, then loosen the nut 6 at the left end of the unloading rod 1-4, rotate the unloading rod 1-4 so that the width direction of the rectangular section is aligned with the first strip hole 1-1-4 and slide into it. Move the unloading rod 1-4 toward the center of the winding drum 1 so that the old metal wire wound on the winding rod 1-3 changes from a tight state to a loose state, and can be easily removed from the right end of the winding rod. Then move the guide plate 5 to the right to complete the positioning of the right end of the unloading rod 1-4 and the winding rod 1-3. Fit the flange 1-2-1 with the right end of the unloading rod 1-4 and the winding rod 1-3. The winding drum 1 is reassembled to prepare for the next operation.
