Description

Technical Field

[0001] This utility model relates to the field of wire electrical discharge machining (EDM) technology, specifically to a wire electrical discharge machining coolant collection device. Background Technology

[0002] Electrical discharge wire cutting, or wire EDM for short, is a cutting method developed from electrical discharge drilling and forming. A conductive medium (usually electrolyte) is coated along the metal surface. When the applied voltage reaches a certain value (10-15kV), the conductive medium breaks down, generating a spark discharge that vaporizes the metal, achieving a small cutting depth (typically only a few micrometers). As the spark discharge continues, the small hole gradually enlarges, forming a continuous trajectory. The electrode wire continuously moves and approaches the workpiece until the entire workpiece is cut. This is a high-speed cutting method.

[0003] Coolant effectively reduces the temperature of the spark discharge during wire electrical discharge machining (EDM), preventing workpiece damage due to high temperatures. It also adsorbs and removes molten metal particles, preventing contamination and damage to the workpiece surface. Furthermore, it acts as a lubricant, reducing friction between the electrode wire and the workpiece surface and improving cutting efficiency.

[0004] Coolant ensures that metal particles and other impurities in the coolant are removed, preventing damage to the equipment and maintaining the cleanliness and effectiveness of the coolant. If the coolant is not recovered in a timely manner, impurities in the coolant may damage the electrode wire and workpiece surface, affecting cutting quality and efficiency. Therefore, we propose an EDM wire cutting coolant collection device to ensure the recovery and effective utilization of the coolant. Utility Model Content

[0005] The purpose of this invention is to provide a device for collecting coolant in wire electrical discharge machining (EDM) to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electrical discharge wire cutting coolant collection device, comprising a base, an electrical discharge wire cutting machine mounted on the rear side of the upper surface of the base, a handwheel slide provided on the front side wall of the electrical discharge wire cutting machine, and the lower surface of the handwheel slide fixedly connected to the upper surface of the base, a concave box fixedly connected to the upper surface of the handwheel slide, a through groove provided on the rear side wall of the concave box, and the through groove fitting into the cutting part of the electrical discharge wire cutting machine, one side of the inner cavity of the concave box being inclined, a square tube fixedly connected to the outer wall of the inclined side of the concave box, and a liquid storage structure fixedly connected to the side wall of the base, with the top of the liquid storage structure corresponding to the lower surface of the square tube.

[0007] Preferably, the liquid storage structure includes a liquid storage tank, which is fixedly connected to the side wall of the base. The top of the liquid storage tank corresponds to the lower surface of the square tube. A through-hole plate is provided at the top of the inner cavity of the liquid storage tank. The side wall of the through-hole plate is clearance-fitted with the inner cavity of the liquid storage tank. A round hole block is fixedly connected to one side of the upper surface of the through-hole plate. The round hole block is fixedly connected to the liquid storage tank by bolts.

[0008] Preferably, the device also includes a clamping structure, wherein there are two clamping structures arranged laterally symmetrically, the clamping structures are fixedly connected to the inner cavity of the concave box, and the inner side is clearance-fitted with the cutting position of the wire EDM machine.

[0009] Preferably, the clamping structure includes a support plate, the lower surface of which is fixedly connected to the inner cavity of the concave box, inner rods are symmetrically sleeved on the top of the support plate with clearance fit, a clamping block is fixedly connected to the end of the inner rod, a rotating block is sleeved in the inner cavity of the clamping block with rotatable connection, a screw is fixedly connected to the side wall of the rotating block, and the outer wall of the screw is threadedly connected to the inner cavity of the support plate.

[0010] Preferably, a glass plate is fixedly connected to the front side wall of the concave box.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: During wire electrical discharge machining (EDM), a concave box is set at the cutting position. A through groove is opened on one side of the concave box, through which the cutting part of the EDM machine passes, and the metal wire is then connected to the EDM machine. Simultaneously, the through groove extends laterally to avoid affecting the movement of the EDM machine. An incline is set on one side of the concave box, which makes it easier for coolant to accumulate on the inclined side. When it reaches a certain height, it contacts a square tube, which then drains into a liquid storage structure. The liquid storage structure is fixed to one side of the base via a liquid storage tank. The liquid storage tank has a rectangular inlet, and when the handwheel slide moves back and forth, the square tube remains at the top of the liquid storage tank, preventing coolant spillage and allowing for timely coolant recovery. The combination of the concave box and the square tube more effectively collects and guides the coolant flow to the liquid storage structure, thereby improving the coolant recovery rate. It also filters out impurities in the coolant, preventing these impurities from affecting the cutting quality and efficiency. Attached Figure Description

A liquid storage structure 6 is fixedly connected to the side wall of the base 1, and the top of the liquid storage structure 6 corresponds to the lower surface of the square tube 5.

[0019] The liquid storage structure 6 includes a liquid storage tank 61, which is fixedly connected to the side wall of the base 1. The top of the liquid storage tank 61 corresponds to the lower surface of the square tube 5. A through-hole plate 62 is provided at the top of the inner cavity of the liquid storage tank 61. The side wall of the through-hole plate 62 is clearance-fitted with the inner cavity of the liquid storage tank 61. A round hole block 63 is fixedly connected to one side of the upper surface of the through-hole plate 62. The round hole block 63 is fixedly connected to the liquid storage tank 61 by bolts.

[0020] It also includes a clamping structure 8, of which there are two clamping structures 8, which are arranged symmetrically in the horizontal direction. The clamping structures 8 are fixedly connected to the inner cavity of the concave box 3, and the inner side is in clearance fit with the cutting position of the wire EDM machine 7.

[0021] The clamp structure 8 includes a support plate 81. The lower surface of the support plate 81 is fixedly connected to the inner cavity of the concave box 3. The top of the support plate 81 is symmetrically fitted with inner rods 82 with clearance fit. The end of the inner rod 82 is fixedly connected with a clamping block 83. The inner cavity of the clamping block 83 is fitted with a rotating block 85 and is rotatably connected. The side wall of the rotating block 85 is fixedly connected with a screw 84. The outer wall of the screw 84 is threadedly connected to the inner cavity of the support plate 81.

[0022] A glass plate 4 is fixedly connected to the front side wall of the concave box 3.

[0023] Working principle: During wire EDM, a wire EDM machine 7 is mounted on the surface of the base 1, forming a complete cutting machine. A handwheel slide 2 is mounted on the surface of the base 1. The movement of the concave box 3 is controlled by rotating the handwheel of the handwheel slide 2. A through groove is opened on one side of the concave box 3. The cutting part of the wire EDM machine 7 passes through the through groove, and then the metal wire is connected to the wire EDM machine 7. At the same time, the through groove extends laterally to avoid affecting the movement of the concave box 3. Then, it is clamped by the clamping structure 8, which is supported by symmetrical support plates 8. 1, as the main body, is set on both sides of the cutting part of the wire EDM machine 7, and is higher than the metal wire. An inner rod 82 is sleeved inside the cavity of the support plate 81. The inner rods 82 are symmetrically arranged and can slide inside the cavity of the support plate 81.

A screw 84 is fixed to the other end of the rotating block 85. The screw 84 is threadedly connected to the cavity of the support plate 81. When the screw 84 is rotated, the screw 84 moves inside the cavity of the support plate 81, and the other end rotates inside the cavity of the clamping block 83 via the rotating block 85, causing the clamping blocks 83 on both sides to move. Moving inwards, the workpiece to be cut can be clamped, and simultaneously cut by the wire EDM machine 7. The workpiece is completely severed by moving the handwheel slide 2. During the cutting process, the wire EDM machine 7 is cooled by coolant to reduce the temperature during spark discharge and prevent damage to the workpiece due to high temperature. An incline is provided on one side of the concave box 3, where coolant accumulates. When it reaches a certain height, it contacts the square tube 5, which then drains towards the liquid storage structure 6 on one side of the base 1. The liquid storage structure 6 is connected to the liquid storage tank 6. 1. Fixed to one side of the base 1, and the liquid storage tank 61 has a rectangular inlet. When the handwheel slide 2 moves back and forth, the square tube 5 is always at the top of the liquid storage tank 61 to prevent the coolant from spilling. The coolant can absorb and remove molten metal particles and flow into the liquid storage tank 61. At the same time, a through-hole plate 62 is provided in the inner cavity of the liquid storage tank 61 to filter impurities. The through-hole plate 62 is fixed by a round hole block 63 on one side and is connected by bolts. The coolant is recovered in time. Impurities in the coolant may damage the electrode wire and the surface of the workpiece, affecting the cutting quality and efficiency.
