AI Technical Summary
Existing EDM machines for copper electrode processing are prone to damage during replacement or maintenance, mainly because the main body of the EDM machine is easily detached during disassembly due to its fixed structure.
A discharge motor including a pushing structure and a supporting structure was designed. By rotating the third bolt, the insertion plate is separated from the rotating plate. Combined with the cooperation of the spring and the slide rod, the main body of the discharge motor can be stably tilted and slid, which facilitates disassembly and maintenance.
This effectively prevents damage to the main body of the discharge generator from impacts during disassembly, improves the convenience of replacement and maintenance, and reduces the probability of damage.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of discharge machine technology, specifically to a discharge machine for processing copper electrodes. Background Technology
[0002] Electrical discharge machining (EDM) is a special machining technology widely used in mold manufacturing and machining industries. It can be used to process ultra-hard materials and complex-shaped workpieces that are difficult to machine using traditional cutting methods.
[0003] For example, an electrical discharge machine (EDM) for processing copper electrodes in molds, with authorization announcement number "CN216462288U," uses a rotating rod to drive a clamping fixture, thereby rotating the workpiece inside the fixture. This allows for adjustment of the workpiece's angle during processing, facilitating operation and improving worker efficiency. However, the device is secured to the main body of the EDM with two bolts. When the main body needs replacement, loosening the bolts causes it to lose support, making it prone to falling during replacement or repair, and thus easily damaged. Utility Model Content
[0004] The purpose of this invention is to solve the problem of easy damage during device replacement, and to propose a discharge machine for copper electrode processing.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] Design a discharge machine for processing copper electrodes, including a housing and a discharge machine body. The inner wall of the housing is fitted to the discharge machine body. The outer wall of the housing is provided with a support structure. The inside of the housing is provided with a pushing structure. The lower end of the housing has a through hole. The left end of the inner wall of the housing has a groove. The upper end of the discharge machine body is electrically connected to a power line. The lower end of the discharge machine body is electrically connected to a copper tube.
[0007] Preferably, the pushing structure includes a support plate and a slide rod. The outer wall of the support plate is fixedly connected to the inner wall of the outer shell. The support plate is slidably connected to the slide rod through a through hole on its surface. A disk is fixedly connected to one end of the slide rod. The disk and the support plate are respectively fixedly connected to both ends of the spring. The other end of the slide rod is movably connected to the push plate through a pin.
[0008] Preferably, the outer wall of the pusher plate is in contact with the main body of the discharge machine, and the lower end of the copper tube penetrates the outer shell.
[0009] Preferably, the right end of the outer casing abuts against the mounting plate, and the mounting plate is threadedly connected to the outer casing by two first bolts and a second bolt.
[0010] Preferably, the support structure includes a rotating plate and insert plates. The rotating part of the rotating plate is movably connected to the outer shell through a bearing. The outer wall of the rotating plate is in contact with two insert plates. The outer walls of the insert plates are slidably connected to two frames respectively. One end of each frame is fixedly connected to the outer shell. Each frame is threadedly connected to two third bolts through threaded holes on its surface. One end of each third bolt is inserted into the insert plates on both sides respectively. An inclined plate is fixedly connected to the left end of the outer shell.
[0011] Preferably, the outer wall of the rotating plate is in contact with the main body of the discharge machine.
[0012] The present invention discloses a discharge machine for processing copper electrodes, which has the following advantages: By cooperating with the push structure and the support structure, the operator rotates the third bolts on both sides, so that the third bolts on both sides are no longer inserted with the insert plates on both sides, so that the insert plates on both sides can be pulled out and separated from the surface of the rotating plate. The rotating plate can then rotate to a state of contact with the inclined plate and stop rotating. At the same time, under the pull of the spring, the disc moves, causing the slide rod to slide in the through hole on the surface of the support plate. The slide rod pushes the upper end of the discharge machine body through the push plate, causing the discharge machine body to tilt towards the rotating plate. The operator can then pull the discharge machine body out along the surface of the rotating plate for maintenance. The discharge machine body can be stably supported, making replacement more convenient and reducing the probability of damage. Attached Figure Description

Detailed Implementation
[0020] The present invention will be further described below with reference to the accompanying drawings:
[0021] See attached document Figure 1-6 In this embodiment, a discharge machine for processing copper electrodes includes a housing 1 and a discharge machine body 3. The inner wall of the housing 1 is attached to the discharge machine body 3. The outer wall of the housing 1 is provided with a support structure 2. The inside of the housing 1 is provided with a pushing structure 9. The lower end of the housing 1 is provided with a through hole. The left end of the inner wall of the housing 1 is provided with a groove. The upper end of the discharge machine body 3 is electrically connected to a power line 4. The discharge machine body 3 is already very mature in the prior art and will not be described in detail again. The lower end of the discharge machine body 3 is electrically connected to a copper tube 5.
[0022] The outer wall of the push plate 905 is in contact with the main body 3 of the discharge machine. The lower end of the copper tube 5 passes through the outer shell 1. The right end of the outer shell 1 is pressed against the mounting plate 6. The mounting plate 6 is threadedly connected to the outer shell 1 by two first bolts 7 and a second bolt 8. The outer wall of the rotating plate 201 is in contact with the main body 3 of the discharge machine.
[0023] The pushing structure 9 includes a support plate 903 and a slide rod 904. The outer wall of the support plate 903 is fixedly connected to the inner wall of the outer shell 1. The support plate 903 is slidably connected to the slide rod 904 through a through hole on its surface. One end of the slide rod 904 is fixedly connected to a disc 901. The disc 901 and the support plate 903 are respectively fixedly connected to both ends of a spring 902. The elastic coefficient of the spring 902 is determined according to actual needs and meets the working requirements. The other end of the slide rod 904 is movably connected to a push plate 905 through a pin.
[0024] The support structure 2 includes a rotating plate 201 and an insert plate 203. The rotating part of the rotating plate 201 is movably connected to the outer shell 1 through a bearing. The outer wall of the rotating plate 201 is in contact with the two insert plates 203. The outer walls of the insert plates 203 are slidably connected to the two frames 205 respectively. One end of the two side frames 205 is fixedly connected to the outer shell 1. The frames 205 are threadedly connected to the two third bolts 204 through threaded holes on their surfaces. One end of the two side third bolts 204 is inserted into the two side insert plates 203 respectively. An inclined plate 202 is fixedly connected to the left end of the outer shell 1.
[0025] Working principle:
[0026] The mounting plate 6 in this device needs to be fixed to the multi-axis linkage structure of the EDM machine tool so that the multi-axis linkage can drive the mounting plate 6 to move and control the EDM machine body 3 to perform discharge operation. The high temperature formed by the discharge channel through the copper tube 5 causes the local metal on the workpiece surface to melt and vaporize rapidly. When the voltage between the electrodes reaches the breakdown threshold, the insulating medium is locally ionized to form a plasma discharge channel with a current density as high as 10. 6 ~10 7 A / cm 2 The instantaneous temperature can reach over 10,000°C. This process takes only microseconds and is accompanied by a high-pressure explosion effect. The molten metal is ejected in the form of particles under the explosion pressure, forming tiny pits that allow the mold to be precisely machined.
[0027] When the main body 3 of the discharge machine needs to be disassembled and repaired, the operator rotates the third bolts 204 on both sides, so that the third bolts 204 on both sides are no longer inserted with the insert plates 203 on both sides, so that the insert plates 203 on both sides can be pulled out, so that the insert plates 203 on both sides can be separated from the surface of the rotating plate 201, so that the rotating plate 201 can be rotated to the state of being in contact with the inclined plate 202 and stop rotating. At the same time, under the pull of the spring 902, the disc 901 is driven to move, so that the slide rod 904 slides in the through hole on the surface of the support plate 903. The slide rod 904 pushes the upper end of the discharge machine main body 3 through the push plate 905, so that the discharge machine main body 3 tilts towards the rotating plate 201. The operator turns the discharge machine main body 3 so that the lower left corner of the discharge machine main body 3 enters the groove on the inner wall of the outer shell 1, so that the rotation center of the discharge machine main body 3 is restricted, reducing the probability of damage caused by the copper tube 5 hitting the outer shell 1 when the discharge machine main body 3 slides on the slide when tilting, so that the discharge machine main body 3 tilts to the state of being in contact with the inclined plate 202. Figure 4 Once the discharge machine body 3 is in the correct state, the operator can simply pull it out along the surface of the rotating plate 201 and then perform maintenance on the discharge machine body 3.
[0028] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
