Description

Technical Field

[0001] This utility model relates to the field of wire cutting technology, and in particular to a wire cutting device. Background Technology

[0002] Wire EDM is a special processing technology that uses pulsed spark discharge to remove metal. It precisely cuts conductive materials by moving a thin metal wire (electrode wire).

[0003] Existing wire EDM equipment typically involves immersing the workpiece in an insulating liquid within the device before cutting it using a wire cutting mechanism. However, the cutting process generates metal debris, and existing equipment lacks an integrated structure for filtering this debris. This debris easily mixes with the insulating liquid, affecting the stability of the wire cutting mechanism's discharge and ultimately reducing the cutting quality. Therefore, we provide a wire EDM device to address this issue. Utility Model Content

[0004] To address the problem of difficulty in filtering out metal debris mixed in insulating liquid in the aforementioned background technology, this utility model provides a wire cutting device.

[0005] This utility model is achieved by the following technical solution: a wire cutting device, including a box and a filter assembly, a bracket is fixedly connected to the box, a servo electric cylinder is fixedly connected to the bracket, a wire cutting mechanism is fixedly connected to the telescopic end of the servo electric cylinder, a filter plate is provided inside the box, and a support base is fixedly connected to the bottom of the box.

[0006] The filter cake assembly includes a frame positioned below the filter plate. Top rods are uniformly fixed to the top of the frame. Four sets of vertical rods are symmetrically fixed to the top of the frame, penetrating the filter plate. A ring is fixedly fitted around the outside of each vertical rod. A connecting rod is fixedly connected to the top of each vertical rod via a connecting plate. A bidirectional lead screw is rotatably connected to the support base. Moving plates are threaded to the outside of both sides of the bidirectional lead screw. A connecting rod is hinged between the moving plates and the connecting rod on the same side via a hinge. A motor is fixedly connected to the support base, with the rotor end of the motor coaxially fixed to one end of the bidirectional lead screw. Four sets of fixing rods are symmetrically fixed to the bottom of the filter plate, penetrating the housing. Four sets of fixing frames are symmetrically fixed to the bottom of the housing, slidingly connected to the fixing rods on the same side. Springs are fitted around the outside of each fixing rod.

[0007] As a further improvement to the above solution, the position of the filter holes on the filter plate corresponds to the position of the top rod, and the diameter of the filter holes on the filter plate is adapted to the diameter of the top rod.

[0008] As a further improvement to the above solution, two sets of guide rods are symmetrically fixedly connected to the support base, and the guide rods are simultaneously slidably connected to the two sets of moving plates.

[0009] As a further improvement to the above solution, a sealing ring is added to the sliding connection between the box and the fixed rod.

[0010] As a further improvement to the above solution, two sets of guide frames are symmetrically fixedly connected to both sides of the box, and the guide frames are slidably connected to the connecting rods on the same side.

[0011] As a further improvement to the above solution, the two ends of the spring are respectively fixedly connected to the external protrusion of the fixing rod and the fixing frame.

[0012] As a further improvement to the above solution, four sets of connecting frames are symmetrically fixedly connected to the top of the filter plate. A screw is threadedly connected to the connecting frame. A circular pressure plate is rotatably connected to the bottom end of the screw, and a knob is coaxially fixedly connected to the top end of the screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model utilizes a motor to drive a bidirectional lead screw, employing a sliding connection between the moving plate and the guide rod, and a threaded connection between the moving plate and the bidirectional lead screw. This allows two sets of moving plates to move simultaneously in opposite directions. A sliding connection between the connecting rod and the guide frame, and a hinged connection between the connecting rod, the moving plate, and the connecting rod, enable the frame to descend as the moving plate moves. This allows the top rod to move out of the filter holes on the filter plate. As the frame descends, when the ring contacts the filter plate, it causes the filter plate to descend as well, immersing the workpiece in the insulating liquid for processing. At this time, the fixed rod descends along with the frame and compresses the spring. When the wire cutting ends and the drive frame resets, the spring's rebound action causes the filter plate to reset as well. This automatically removes metal debris generated during wire cutting from the insulating liquid, facilitating unified cleaning. This design is highly practical.

[0015] 2. When the filter plate and frame are reset sequentially, the push rod on the frame will automatically insert into the filter hole on the filter plate, thereby pushing out the metal debris inside the filter hole and avoiding residue during cleaning, thus effectively ensuring the quality of the workpiece during wire cutting.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example 1:

[0023] Please combine Figure 1-3 The wire cutting device of this embodiment includes a housing 1, a bracket fixedly connected to the housing 1, a servo electric cylinder 2 fixedly connected to the bracket, a wire cutting mechanism 3 fixedly connected to the telescopic end of the servo electric cylinder 2, a filter plate 4 provided inside the housing 1, and a support base fixedly connected to the bottom of the housing 1.

[0024] A filter assembly for automatically removing metal debris includes a frame 101 positioned below a filter plate 4. Top rods 102 are uniformly fixedly connected to the top of the frame 101. Four sets of vertical rods 103 are symmetrically fixedly connected to the top of the frame 101, penetrating the filter plate 4. A ring 104 is fixedly fitted around the outside of each vertical rod 103. A connecting rod 105 is fixedly connected to the top of each vertical rod 103 via a connecting plate. A bidirectional lead screw 106 is rotatably connected to a support base. Moving plates 107 are threaded onto both sides of the bidirectional lead screw 106. A connecting rod 108 is hinged between the moving plate 107 and the connecting rod 105 on the same side. A motor is fixedly connected to the support base, with the rotor end of the motor coaxially fixedly connected to one end of the bidirectional lead screw 106. Four sets of fixing rods 109 are symmetrically fixedly connected to the bottom of the filter plate 4, penetrating the housing 1. Four sets of fixing rods 109 are symmetrically fixedly connected to the bottom of the housing 1. The frame and the fixed frame are slidably connected to the fixed rod 109 on the same side. A spring 110 is sleeved on the outside of the fixed rod 109. The two ends of the spring 110 are fixedly connected to the external protrusion of the fixed rod 109 and the fixed frame, respectively. The position of the filter hole on the filter plate 4 corresponds to the position of the top rod 102. The diameter of the filter hole on the filter plate 4 is adapted to the diameter of the top rod 102, which facilitates the complete removal of metal debris from the filter hole. Two sets of guide rods 5 are symmetrically fixedly connected to the support base, and the guide rods 5 are slidably connected to two sets of moving plates 107 at the same time, which can play a certain guiding role in the horizontal movement of the moving plates 107. A sealing ring is added to the sliding connection between the box body 1 and the fixed rod 109 to increase the sealing performance and prevent the leakage of insulating liquid. Two sets of guide frames are symmetrically fixedly connected to both sides of the box body 1, and the guide frames are slidably connected to the connecting rod 105 on the same side, which can play a certain guiding role in the vertical movement of the connecting rod 105.

[0025] The implementation principle of a wire cutting device in this embodiment is as follows: First, the workpiece is placed on the filter plate 4. Then, the motor is started, and the motor drives the bidirectional lead screw 106 to rotate. The sliding connection between the moving plate 107 and the guide rod 5, and the threaded connection between the moving plate 107 and the bidirectional lead screw 106, allow the two sets of moving plates 107 to move simultaneously in opposite directions. The sliding connection between the connecting rod 105 and the guide frame, and the hinge connection between the connecting rod 105 and the moving plate 107 and the connecting rod 108, allow the frame 101 to descend as the moving plate 107 moves. This allows the top rod 102 to move out of the filter hole on the filter plate 4. As the frame 101 continues to descend, when the ring 104 contacts the filter plate 4, it causes the filter plate 4 to descend as well, allowing the workpiece to be cut to be immersed in the insulating liquid for easier cutting. During processing, the fixed rod 109 descends and compresses the spring 110. Then, the servo cylinder 2 is activated, which precisely pushes the wire cutting mechanism 3 closer to the workpiece. The wire cutting mechanism 3 then cuts the workpiece. Subsequently, the motor is reversed to reset the frame 101. At this time, the spring 110's own rebound action allows the filter plate 4 to reset as well, thus automatically removing the metal debris generated during wire cutting from the insulating liquid for easy cleaning. Simultaneously, after the filter plate 4 and frame 101 reset, the push rod 102 on the frame 101 automatically re-inserts into the filter hole on the filter plate 4, thereby pushing out the metal debris inside the filter hole and preventing residue during cleaning. This effectively ensures the quality of the workpiece during wire cutting. Finally, the workpiece is removed and the surface of the filter plate 4 is cleaned.

[0026] Example 2:

[0027] Based on Example 1, this embodiment is further improved in that: four sets of connecting frames are symmetrically fixedly connected to the top of the filter plate 4, and screws 6 are threadedly connected to the connecting frames. A circular pressure plate 7 is rotatably connected to the bottom end of the screws 6, and a knob is coaxially fixedly connected to the top end of the screws 6. By rotating the screws 6 through the knob, the circular pressure plate 7 can be driven to descend and contact the surface of the workpiece, thereby clamping and fixing the workpiece to ensure stability during wire cutting.
