Description

Technical Field

[0001] This utility model relates to the field of wire cutting technology, specifically a wire cutting device for inner holes of copper sleeves that eliminates the need for wire threading. Background Technology

[0002] Wire EDM is a machining method that uses a moving metal wire (molybdenum wire, copper wire, or alloy wire) as an electrode wire. The high temperature generated by the pulsed electric spark discharge between the electrode wire and the workpiece melts or vaporizes the metal, forming a kerf, thereby cutting out the part.

[0003] When wire cutting the inner hole of a copper bushing, it is necessary to disassemble the guide wheel and other devices, and then pass the electrode wire through the inner hole of the copper bushing. Figure 1 As shown, each cutting process requires disassembling and reassembling the electrode wire, which is cumbersome, greatly prolongs the production time, and reduces the production efficiency. Therefore, this wire-threading-free device was designed to improve the winding of the electrode wire, so that the electrode wire can be inserted into the inner hole of the copper sleeve for processing without disassembling the device. Utility Model Content

[0004] The purpose of this invention is to provide a wire cutting device for copper bushings without threading the electrode wire. A sliding frame slides within a slide rail, and the electrode wire is wound vertically around the winding assembly. By moving the sliding frame up and down, the electrode wire is inserted into the copper bushing for cutting. This eliminates the need to disassemble the electrode wire and guide wheel on traditional wire cutting equipment. Cutting can be controlled simply by sliding the sliding frame, saving the equipment disassembly and electrode wire threading process, and significantly improving the processing efficiency of batch copper bushings.

[0005] This utility model provides the following technical solution: a wire cutting device for inner hole of copper sleeve without threading, including an upper support and a lower support. A connecting frame is fixed on the top surface of the upper support, and a slide rail is connected to the side of the connecting frame. A sliding frame slides in the slide rail, and a winding assembly is installed on the sliding frame. An electrode wire is wound on the winding assembly. The electrode wire is in the shape of a vertical strip on the sliding frame. The sliding frame slides up and down to insert the electrode wire into the copper sleeve for processing. The winding assembly includes an upper wheel and a lower wheel distributed vertically. The upper wheel and the lower wheel are respectively located on the upper and lower parts of the sliding frame. The upper end of the electrode wire is wound around the upper wheel, and the lower end of the electrode wire is wound around the lower wheel. During cutting, the upper wheel and the lower wheel are located above and below the copper sleeve, and the electrode wire is inserted into the copper sleeve from above to cut the copper sleeve.

[0006] Furthermore, the winding assembly also includes an infeed wheel and an outfeed wheel. The infeed wheel is rotatably connected to the upper support via a pin, and the outfeed wheel is rotatably connected to the lower support via a pin. A guide wheel is also rotatably connected to the upper support, and the guide wheel is located below the infeed wheel. At least two guide wheels are rotatably connected to the sliding frame. The electrode wire is led out from the infeed wheel, wound around the upper wheel via the guide wheel, then led to the lower wheel, and wound around the outfeed wheel via the guide wheel and the guide wheel. By setting the guide wheel and the guide wheel, the electrode wire is guided so that the inner electrode wire does not interfere with the copper sleeve during the up and down movement.

[0007] Furthermore, a tensioning wheel is rotatably connected to the sliding frame. The tensioning wheel is located on one side of the guide wheel, which keeps the electrode wire in a taut state and ensures cutting accuracy.

[0008] Furthermore, a drive assembly is fixed on the side of the slide rail, the drive assembly is located above the slide frame, the drive assembly is connected to the slide frame, and drives the slide frame to move up and down.

[0009] Furthermore, the drive component is a cylinder or an electric push rod.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: A sliding frame slides inside the slide rail, and the electrode wire is wound around the winding assembly so that the electrode wire is in the shape of a vertical strip. By moving up and down the sliding frame, the electrode wire is inserted into the copper sleeve during cutting. It is no longer necessary to disassemble the electrode wire and guide wheel on the traditional wire cutting equipment. Cutting can be carried out simply by sliding the sliding frame to insert the electrode wire into the copper sleeve. This eliminates the need for equipment disassembly and the electrode wire insertion process, and greatly improves the processing efficiency of batch copper sleeves. Attached Figure Description

A sliding frame 3 slides in the slide rail 2. A winding assembly is installed on the sliding frame 3. An electrode wire is wound on the winding assembly. The electrode wire is in the shape of a vertical strip on the sliding frame 3. The vertical strip formed by the winding of the electrode wire is inserted into the copper sleeve 7 from above under the up and down movement of the sliding frame 3 to process the copper sleeve 7. The electrode wire is located on the outside of the sliding frame 3. The winding assembly includes an upper wheel 31 and a lower wheel 32 distributed vertically. The upper wheel 31 and the lower wheel 32 are located on the upper and lower parts of the sliding frame 3, respectively. The upper end of the electrode wire is wound around the upper wheel 31, and the lower end of the electrode wire is wound around the lower wheel 32. The electrode wire is vertical outside the upper wheel 31 and the lower wheel 32. During cutting, the upper wheel 31 and the lower wheel 32 are located above and below the copper sleeve 7. The electrode wire is inserted into the copper sleeve 7 from above to cut the copper sleeve 7. The electrode wire moves up and down with the sliding frame 3. By adjusting the height of the sliding frame 3, the height of the electrode wire is controlled, and the outer electrode wire is moved into the copper sleeve 7 to cut the copper sleeve 7. After cutting, the electrode wire can be moved to the top of the copper sleeve 7, reducing the preparation time before cutting.

At least two guide wheels 33 are rotatably connected to the sliding frame 3. The guide wheels 33 guide the winding direction of the electrode wire. The electrode wire is led out from the infeed wheel 4, passes through the guide wheels 33, winds around the upper wheel 31, and then leads to the lower wheel 32. After passing through the guide wheels 33 and the guide wheels 35, it winds around the outfeed wheel 5. The movement of the sliding frame 3 can drive the electrode wire to slide on the guide wheels 33, the upper wheel 31, and the lower wheel 32.

[0015] A tensioning wheel 34 is also rotatably connected to the sliding frame 3. The tensioning wheel 34 is located on one side of the guide wheel 33. The total length of the electrode wire on the winding assembly remains unchanged. Furthermore, under the action of the tensioning wheel 34, the electrode wire is always kept in a taut state to ensure cutting accuracy.

[0016] A drive assembly 21 is bolted to the side of the slide rail 2. The drive assembly 21 is located above the slide frame 3 and is connected to the slide frame 3. It drives the slide frame 3 to move up and down. The drive assembly 21 is a cylinder or an electric push rod.
