Description

Technical Field

[0001] This utility model relates to the field of medium-speed wire EDM machine technology, and in particular to a high-stability medium-speed wire EDM machine with an automatic compensation structure. Background Technology

[0002] Medium-speed wire EDM machines are a type of electrical discharge wire cutting machine. Developed from fast-speed wire EDM machines, their wire feed speed and workpiece quality fall between those of fast and slow wire EDM machines. Medium-speed wire EDM machines use molybdenum wire as the electrode wire, which moves continuously during the machining process. This machine is mainly used for cutting metal materials. Through the electrical discharge between the electrode wire and the workpiece, excess metal is removed, thus shaping the workpiece into the desired form.

[0003] During operation, the wire EDM machine connects the workpiece and the electrode wire (molybdenum wire) to a pulse power supply. The molybdenum wire is supplied by a wire spool and moves along the wire feed track. In the machining area, the molybdenum wire maintains a certain discharge gap with the workpiece, while working fluid is sprayed. The instantaneous high temperature generated by the pulse power supply discharge melts and vaporizes the metal on the workpiece surface, thereby removing the metal. In the multiple cutting processes, the first cut uses a larger current to quickly remove most of the excess material; subsequent cuts gradually reduce the current to improve machining accuracy and surface finish. Through the coordination of multiple cuts, the workpiece is ultimately machined to the required shape and precision.

[0004] In existing technologies, molybdenum wire in some medium-speed wire EDM machines is easily affected by dust during processing. Due to the lack of an effective cleaning structure, a large amount of dust accumulates on the surface of the molybdenum wire on the winding drum after prolonged use. This dust interferes with the electrical discharge process between the molybdenum wire and the workpiece, leading to a decrease in machining accuracy. Furthermore, excessive dust accumulation can cause localized overheating of the molybdenum wire, accelerating its wear and shortening its service life. Therefore, a high-stability medium-speed wire EDM machine with an automatic compensation structure is proposed to solve these problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a high-stability medium-speed wire EDM machine tool with an automatic compensation structure. It aims to improve the problem in some existing medium-speed wire EDM machines where a large amount of dust accumulated on the surface of the molybdenum wire on the winding drum after long-term use interferes with the discharge process between the molybdenum wire and the workpiece, resulting in a decrease in machining accuracy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-stability medium-speed wire EDM machine tool with an automatic compensation structure includes a medium-speed wire EDM machine tool body, a winding drum fixedly connected to the rear top of the medium-speed wire EDM machine tool body, a wire feeding track fixedly connected to the outside of the medium-speed wire EDM machine tool body, a cleaning mechanism fixedly connected to the top rear end of the medium-speed wire EDM machine tool body, and a water blocking mechanism fixedly connected to the front end of the medium-speed wire EDM machine tool body.

[0008] The cleaning mechanism includes a square box, the front end of which is fixedly connected to the rear end of the main body of the wire EDM machine. A connecting pipe is fixedly connected to the bottom end of the square box, and an air inlet pipe is fixedly connected to the bottom end of the connecting pipe.

[0010] The water-blocking mechanism includes a water-blocking plate. A worktable is fixedly connected to the front end of the main body of the wire EDM machine. The bottom side of the water-blocking plate contacts the top side of the worktable. Square blocks are fixedly connected to both the left and right sides of the water-blocking plate. A cavity is opened inside the square block. A square plate is slidably connected to the inner wall of the cavity. A locking rod is fixedly connected to the middle of the square plate. A spring is sleeved on the outside of the locking rod.

[0011] As a further description of the above technical solution:

[0012] A V-shaped plate is fixedly connected to the inner wall of the square box, and a dust filter plate is fixedly connected to both the left and right sides of the V-shaped plate.

[0013] As a further description of the above technical solution:

[0014] The two dust filter plates are fixedly connected to the left and right inner walls of the square box on opposite sides. Collection boxes are slidably connected to the left and right sides of the inside of the square box, and handles are fixedly connected to the rear sides of the two collection boxes.

[0015] As a further description of the above technical solution:

[0016] A positioning plate is fixedly connected to the top of the workbench. The outer wall of the positioning plate contacts the inner wall of the baffle plate. A circular hole is opened inside the positioning plate, and the outside of the clamping rod engages with the inside of the circular hole.

[0017] As a further description of the above technical solution:

[0018] The external part of the lever is slidably connected to the inside of the baffle plate, and the external part of the lever is slidably connected to the inside of the square block;

[0023] This utility model has the following beneficial effects:

[0024] 1. In this invention, a fan generates power to circulate air, drawing dust from the surface of the molybdenum wire. The inlet pipe and connecting pipe smoothly transmit the dust-laden air to the square box. A V-shaped plate inside the square box guides the air and dust to flow to both sides, while a dust filter plate blocks the dust, which falls into the collection box. This ensures that dust on the surface of the molybdenum wire is effectively cleaned, preventing dust accumulation that could affect its performance. Excessive dust on the surface of the molybdenum wire can lead to unstable discharge between the wire and the workpiece, affecting machining accuracy. The air passing through the dust filter plate is then ejected from the nozzle via the fan and outlet pipe, cooling the molybdenum wire in the square box, thereby extending its service life, reducing the frequency of replacement, and lowering production costs.

[0025] 2. In this utility model, when it is necessary to install the baffle plate, the operator pulls the pull plate, which moves the clamping rod and the square plate to compress the spring. After placing the baffle plate on the worktable along the positioning plate, the pull plate is released. The spring drives the square plate and the clamping rod to engage with the round hole of the positioning plate, realizing quick installation, protecting the machine tool from the damage of coolant, thereby extending the service life of the machine tool and reducing the maintenance cost of the machine tool.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment of a high-stability medium-speed wire EDM machine tool with an automatic compensation structure. The machine tool includes a main body 1, a wire winding drum 2 fixedly connected to the rear top of the main body 1, a wire conveying track 3 fixedly connected to the outside of the main body 1, a cleaning mechanism fixedly connected to the top rear end of the main body 1, and a water-blocking mechanism fixedly connected to the front end of the main body 1. The main body 1 provides a stable mounting platform for components such as the wire winding drum 2, the wire conveying track 3, the cleaning mechanism, and the water-blocking mechanism. Its structural design ensures overall stability during processing, withstands various forces during processing, and guarantees the accuracy of the coordinated operation of each component. The main function of the wire winding drum 2 is to store molybdenum wire, which is released or retracted during processing by rotation. The wire conveying track 3 provides a precise guiding path for the movement of the molybdenum wire.

[0035] The cleaning mechanism includes a square box 4, the front end of which is fixedly connected to the rear end of the main body 1 of the wire winding machine. The square box 4 provides a closed space for other components in the cleaning mechanism, allowing dust collection and airflow to occur in a relatively independent environment. This space helps to centrally handle dust and prevents dust from spreading to other parts of the machine tool and affecting its normal operation. A connecting pipe 5 is fixedly connected to the bottom end of the square box 4, and an air inlet pipe 6 is fixedly connected to the bottom end of the connecting pipe 5. The connecting pipe 5 acts as a bridge connecting the air inlet pipe 6 and the square box 4. An air inlet hood 7 is fixedly connected to the drive end of the air inlet pipe 6. The main function of the air inlet pipe 6 is to transfer the air and dust drawn in by the air inlet hood 7 to the square box 4. An exhaust fan 11 is fixedly connected to the top of the square box 4. The exhaust fan 11 is the power source of the cleaning mechanism, generating power to drive airflow by turning on the exhaust fan 11. The function of the air inlet hood 7 is to directly cover the surface of the molybdenum wire on the winding drum 2. By turning on the exhaust fan 11 on the square box 4, the dust on the surface of the molybdenum wire is drawn into the air inlet hood 7. An exhaust pipe 12 is fixedly connected to the top of the exhaust fan 11, and an air nozzle 13 is fixedly connected to the output end of the exhaust pipe 12. The function of the air nozzle 13 is to spray out the cleaned and cooled air, which can cool the molybdenum wire on the square box 4 at the same time. A V-shaped plate 8 is fixedly connected to the inner wall of the square box 4, and dust filter plates 9 are fixedly connected to both sides of the V-shaped plate 8. During the cleaning process, when air carrying dust enters the square box 4 through the air inlet pipe 6 and the connecting pipe 5, the V-shaped plate 8 guides the air and dust to flow to both sides. Combined with the dust filter plates 9, the dust is prevented from re-entering the machine tool with the air, thus ensuring the cleaning effect. The two dust filter plates 9 are fixedly connected to the left and right inner walls of the square box 4 on opposite sides. Collection boxes 10 are slidably connected to the left and right sides of the interior of the square box 4, and handles are fixedly connected to the rear of the two collection boxes 10. The collection boxes 10 are used to collect the dust that falls down after being blocked by the dust filter plates 9. Its sliding connection structure makes it easy to clean after the dust collection box is full. The collection box 10 can be easily removed by pulling the handle, the dust can be emptied and then put back in its original position.

[0036] Reference Figure 1 , Figure 2 and Figure 5The water-blocking mechanism includes a water-blocking plate 15. The main function of the water-blocking plate 15 is to prevent coolant and other liquids from splashing onto other parts of the machine tool during workpiece processing. A worktable 14 is fixedly connected to the front end of the main body 1 of the wire EDM machine tool. The bottom side of the water-blocking plate 15 contacts the top side of the worktable 14. Square blocks 16 are fixedly connected to both the left and right sides of the water-blocking plate 15. A cavity 17 is opened inside the square block 16. A square plate 18 is slidably connected to the inner wall of the cavity 17. A locking rod 19 is fixedly connected to the middle of the square plate 18. The square block 16 provides installation space for the square plate 18, locking rod 19 and other components, and limits the movement direction of these components through the internal cavity 17, ensuring that each component can move in the predetermined direction during the installation and disassembly of the water-blocking plate 15. A positioning plate 20 is fixedly connected to the top of the workbench 14. The outer wall of the positioning plate 20 contacts the inner wall of the baffle plate 15. The positioning plate 20 provides a locking position for the locking rod 19. Its contact structure with the baffle plate 15 helps to determine the installation position of the baffle plate 15. A circular hole is opened inside the positioning plate 20, and the outside of the locking rod 19 engages with the inside of the circular hole. The outside of the locking rod 19 is slidably connected to the inside of the baffle plate 15 and the inside of the square block 16. A spring 21 is sleeved on the outside of the locking rod 19. The adjacent sides of the two springs 21 are fixedly connected to the opposite sides of the two square plates 18, and the opposite sides of the two springs 21 are fixedly connected to the opposite inner walls of the two chambers 17. Pulling plates 22 are fixedly connected to the opposite sides of the two locking rods 19, and the adjacent sides of the two pulling plates 22 contact the opposite sides of the two square blocks 16. Spring 21 is the power component during the installation and removal of the baffle 15. Square plate 18 transmits force. When the operator pulls the pull plate 22, square plate 18 slides within chamber 17 and compresses spring 21. When the pull plate 22 is released, square plate 18 moves inward under the elastic force of spring 21, causing locking rod 19 to engage. Locking rod 19 is a key component for the installation and fixation of the baffle 15. By engaging with the round hole on positioning plate 20, it enables the quick installation and fixation of the baffle 15 on the workbench 14, ensuring the stability of the baffle 15 during use.

[0037] Working principle: By turning on the exhaust fan 11 on the square box 4, the power is generated to drive the air to flow. The dust on the surface of the molybdenum wire on the winding drum 2 is sucked in by the air intake hood 7. The air and dust will enter the square box 4 through the air intake pipe 6 and the connecting pipe 5. With the help of the V-shaped plate 8, the air and dust will flow to both sides. Then the air will pass through the dust filter plate 9 and the exhaust fan 11 and the air outlet pipe 12, and finally be sprayed out from the jet nozzle 13. At the same time, the molybdenum wire on the square box 4 is cooled down. The dust will be blocked by the dust filter plate 9 and fall into the collection box 10 by gravity for collection.

[0038] When the workpiece needs to be processed, the operator pulls the pull plate 22 to move the clamping rod 19 and the square plate 18 to compress the spring 21 and place the baffle 15 on the worktable 14 along the positioning plate 20. After the baffle 15 and the positioning plate 20 are engaged, the pull plate 22 is released. The pressure generated by the compressed spring 21 will move the square plate 18 inward, which in turn will move the clamping rod 19 inward and engage with the round hole on the positioning plate 20, thus quickly completing the installation and fixing of the baffle 15. After the workpiece is processed, the baffle 15 can be removed by pulling the pull plate 22.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
