Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire EDM, and in particular to a wire recovery device for a wire EDM machine. Background Technology
[0002] In the field of wire EDM, wire recycling devices are crucial for ensuring the stable operation of the machining machine and improving the reuse rate of the wire.
[0003] However, in existing wire EDM machines, the tension of the wire changes during processing due to factors such as the workpiece being cut. Existing devices struggle to automatically and accurately adjust this tension, leading to wire slack or excessive tightness during operation. This negatively impacts processing accuracy and stability, reducing overall quality. Furthermore, insufficient wire cleaning and drying results in impurities and moisture adhering to the cut wire surface. Existing cleaning components are ineffective at removing these impurities, and the lack of a proper drying function prevents rapid and thorough drying. This not only affects the quality of wire recovery but may also adversely impact subsequent processing. To address these issues, we propose a wire recovery device for wire EDM machines.

A cleaning component is also provided on the outer side of the machine body 1 and is located behind the tension adjustment mechanism. A take-up component is provided at the other end of the wire body 3. The take-up component includes a drive motor 19 and is located on the outer side of the machine body 1. A first vertical plate 22, a second vertical plate 23, and a third vertical plate 24 are fixedly connected to the inner side of the machine body 1. The wire body 3 is slidably connected to the first vertical plate 22, the second vertical plate 23, and the third vertical plate 24.
[0024] In this embodiment, the tension adjustment mechanism includes a first moving wheel 6, which is sleeved on the inner side of the yarn body 3. A first bracket 7 is rotatably connected to the outer side of the first moving wheel 6. The first bracket 7 is fixedly installed on the upper end of the inner cavity of the processing machine body 1. A second moving wheel 8 is arranged below the first moving wheel 6, which is sleeved on the outer side of the yarn body 3. A second bracket 9 is rotatably connected to the outer side of the second moving wheel 8. A connecting rod 10 is fixedly connected to the front end of the second bracket 9.

Both the spring 11 and the circular plate 12 are located on the outer side of the processing machine body 1.
[0025] Specifically, the object to be cut is first placed on the upper end of the placement table 4. At this time, the main body of the processing machine 1 is started, so that the wire body 3 is released from the wire feeding head 2. When the wire body 3 cuts the object, the tension will change. The wire body 3 will push the second moving wheel 8 to move, which in turn drives the connecting rod 10 to slide. When the tension increases, the second moving wheel 8 moves backward, and the circular plate 12 will compress the spring 11. When the tension decreases, the spring 11 pushes the circular plate 12 to cause the second moving wheel 8 to move forward, thereby automatically adjusting the tension of the wire body 3.
[0026] In this embodiment, the space between the first upright plate 22 and the second upright plate 23 is a cleaning chamber. The cleaning component is located inside the cleaning chamber. The cleaning component includes a first cleaning block 15 and a second cleaning block 16. The first cleaning block 15 and the second cleaning block 16 are respectively located on the outside of the wire body 3. A bidirectional lead screw 13 is rotatably connected to the inside of the processing machine body 1. The first cleaning block 15 and the second cleaning block 16 are respectively threaded onto the forward and reverse threaded sections of the bidirectional lead screw 13. A guide rod 14 is slidably connected to the outside of the first cleaning block 15 and the second cleaning block 16. The guide rod 14 is fixedly connected to the inner wall of the processing machine body 1. A handwheel 25 is fixedly connected to one side of the bidirectional lead screw 13. The handwheel 25 is located on the outside of the processing machine body 1.
[0027] Specifically, after the silk thread body 3 is cut, impurities will adhere to the outside. At this time, turn the hand dial 25, which will drive the bidirectional lead screw 13 to rotate. With the guidance of the guide rod 14, the first cleaning block 15 and the second cleaning block 16 can be moved relative to each other, thus adhering to the silk thread body 3. While the silk thread body 3 is moving, wiping and cleaning are achieved.
[0028] In this embodiment, the space between the second vertical plate 23 and the third vertical plate 24 is a drying chamber. A drying fan 17 is fixedly installed on the main body 1 of the processing machine on one side of the drying chamber, and a plurality of ventilation holes 18 are provided on the main body 1 of the processing machine on the other side of the drying chamber.
[0029] Specifically, when the cleaned yarn enters the drying chamber, the drying fan 17 is activated to blow hot air to remove the moisture from the yarn body 3, and the humid air is discharged through the ventilation hole 18 to accelerate the drying of the yarn.
[0030] In this embodiment, the output end of the drive motor 19 is fixedly connected to the take-up reel 21, one end of the wire body 3 is wound around the outside of the take-up reel 21, and the lower end of the drive motor 19 is fixedly connected to the mounting block 20. The drive motor 19 is fixedly mounted on the outside of the processing machine body 1 through the mounting block 20.
[0031] Specifically, by starting the drive motor 19, the take-up reel 21 is rotated, which pulls the wire body 3 back in. The take-up speed can be adjusted by controlling the speed of the drive motor 19 to adapt to different processing needs.
[0032] In this embodiment, the upper end of the cleaning chamber is provided with a maintenance cover plate 5 hinged to the main body 1 of the processing machine, and a handle is fixedly connected to the upper end of the maintenance cover plate 5.
[0033] Specifically, the first cleaning block 15 and the second cleaning block 16 can be inspected or replaced through the inspection cover 5 at the upper end of the cleaning chamber.
[0034] It should be noted that this utility model is a wire recovery device for a slow wire EDM machine. The user first places the object to be cut on the upper end of the placement table 4. Then, the main body 1 of the EDM machine is started, releasing the wire body 3 from the wire feeding head 2. When the wire body 3 cuts the object, tension changes occur, causing the wire body 3 to push the second moving wheel 8 to move, which in turn drives the connecting rod 10 to slide. When the tension increases, the second moving wheel 8 moves backward, and the circular plate 12 compresses the spring 11. When the tension decreases, the spring 11 pushes the circular plate 12, causing the second moving wheel 8 to move forward, thus automatically adjusting the tension of the wire body 3. After cutting, impurities will adhere to the outer side of the wire body 3. At this time, rotating the handwheel 25 will cause the handwheel 25 to... The bidirectional lead screw 13 rotates, and with the guidance of the guide rod 14, the first cleaning block 15 and the second cleaning block 16 can move relative to each other, thus adhering to the yarn body 3 for wiping and cleaning. The first cleaning block 15 and the second cleaning block 16 can be inspected or replaced through the inspection cover 5 at the upper end of the cleaning chamber. When the cleaned yarn enters the drying chamber, the drying fan 17 is started to blow hot air to remove the moisture on the yarn body 3. The humid air is then discharged through the ventilation hole 18 to accelerate the drying of the yarn. The drive motor 19 is started to drive the take-up reel 21 to rotate, pulling the yarn body 3 back. The take-up speed can be adjusted by controlling the speed of the drive motor 19 to adapt to different processing needs, which is quite practical.
