Description

Technical Field

[0001] This utility model relates to the field of wire cutting machines, specifically a wire cutting machine for processing magnets. Background Technology

[0002] Wire EDM, short for CNC wire electrical discharge machining, is a machine tool that uses the principle of electrical discharge to cut workpieces. It mainly consists of three parts: the machine tool, a CNC system, and a high-frequency power supply. A moving metal wire (such as copper or molybdenum wire) serves as the tool electrode, and a pulsed current is applied between the wire and the workpiece. The corrosive effect of the pulsed discharge cuts the contour of the workpiece. Wire EDM machines offer advantages such as high machining accuracy and good surface quality, and are widely used in various industries including motors, electronics, home appliances, and building materials.

[0003] For example, authorization announcement number CN221415266U discloses a wire cutting machine for processing magnets, relating to the field of wire cutting machine technology. This utility model includes a cutting base plate, with a groove on the upper surface of the base plate. The groove has an isosceles trapezoidal cross-section. A U-shaped frame is provided on the upper surface of the base plate, and a slider is fixedly installed on the lower surface of the U-shaped frame. The slider is slidably connected within the groove. A first threaded rod is provided on one side of the base plate. This utility model clamps and fixes the magnet through the cooperation of a second threaded rod, a clamping plate, and a second torsion block. The left and right positions of the magnet are adjusted through the cooperation of the groove, slider, first threaded rod, and first torsion block. This not only prevents the magnet from shifting under force during cutting, thus avoiding affecting the cutting effect, but also allows for more flexible cutting lengths and more precise cutting of magnets of different specifications.

[0004] In the aforementioned technology, the magnet is supported and fixed by a U-shaped frame. However, when the cutting wire descends and completely cuts the magnet, the cutting wire will also cut the U-shaped frame, causing damage to the frame and affecting subsequent use. Therefore, the market urgently needs to develop a wire cutting machine for magnet processing to help people solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to provide a wire cutting machine for processing magnets, in order to solve the problem mentioned in the background art where the magnet is supported and fixed by a U-shaped frame, but when the cutting wire descends and completely cuts the magnet, the cutting wire also cuts the U-shaped frame, causing damage to the U-shaped frame and affecting subsequent use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1-5This utility model provides an embodiment of a wire cutting machine for processing magnetic steel, comprising a support platform 1. Linear guide rails 101 are fixedly connected to both the front and rear ends of the upper middle portion of the support platform 1. Side plates 102 are fixedly connected to both sides of the two linear guide rails 101. A C-shaped clamp 3 is connected to one side of the upper end of the two linear guide rails 101. Linear sliders 301 are fixedly connected to both the front and rear ends of the lower end of the C-shaped clamp 3. The two linear sliders 301 slide between the two linear guide rails 101 respectively. Next, a threaded slider 302 is fixedly connected to the middle of the lower end of the C-shaped clamp 3. A screw 103 is rotatably connected between the middle of the two side plates 102. The screw 103 passes through the middle of the threaded slider 302 at the lower end of the C-shaped clamp 3 and is threadedly connected to the threaded slider 302. A first hydraulic rod 303 is fixedly connected to the middle of the upper end of the C-shaped clamp 3. A pressure plate 304 is provided on the upper inner side of the C-shaped clamp 3. The telescopic end of the lower end of the first hydraulic rod 303 passes through the upper surface of the C-shaped clamp 3 and is fixedly connected to the upper end of the pressure plate 304. A support plate 4 is fixedly connected to the outer side of one side plate 102. A second hydraulic rod 401 is fixedly connected to the middle of the outer side of the support plate 4. The telescopic end of the second hydraulic rod 401 extends through the middle of one side of the support plate 4 to the other side of the support plate 4 and is fixedly connected to a clamping plate 402. The end of the magnet away from the cutting position is inserted into the C-shaped clamp 3. The first hydraulic rod 303 drives the pressure plate 304 to descend and clamp one end of the magnet, thus suspending the cutting position of the magnet. The screw 103 rotates and drives the threaded slider 302 to move. In turn, the threaded slider 302 drives the C-shaped clamp 3 to slide on two linear guide rails 101 through two linear sliders 301. The C-shaped clamp 3 moves the clamped magnet and adjusts the position of the magnet cutting position on the upper end of the support table 1. After the adjustment is completed, the second hydraulic rod 401 extends and the clamping plate 402 contacts the end face of the magnet away from the C-shaped clamp 3 to clamp the magnet, thus achieving double fixation of the magnet.

[0025] Please see Figure 2 and Figure 5 A drive box 2 is fixedly connected to the middle of the outer side of the other side plate 102. A drive motor 201 is fixedly installed inside the drive box 2. One end of the screw 103 passes through the side plate 102 and extends into the drive box 2 and is connected to the drive motor 201 through a coupling. The drive motor 201 drives the screw 103 to rotate.

[0026] Please see Figure 2 , Figure 3 and Figure 4An L-shaped support frame 5 is fixedly connected to the middle of the rear end of the upper surface of the support platform 1. A third hydraulic rod 501 is fixedly connected to the front end of the upper surface of the L-shaped support frame 5. An electrode box 502 is set on the upper inner side of the L-shaped support frame 5. A connecting frame 503 is fixedly connected to one side of the electrode box 502. A cutting line 504 is fixedly set on the inner side of the connecting frame 503. The telescopic end of the lower end of the third hydraulic rod 501 passes through the L-shaped support frame 5 and is fixedly connected to the upper end of the electrode box 502. When the C-shaped clamp 3 moves the magnet to adjust its position, the magnet moves to the lower end of the cutting line 504. The electrode box 502 is lowered by the third hydraulic rod 501, which in turn lowers the electrode box 502, the connecting frame 503, and the cutting line 504. The electrode box 502 is activated to perform pulse spark discharge on the cutting line 504, so that the cutting line 504 cuts the magnet.

[0027] Working Principle: In use, first place the magnet to be processed on the support platform 1 and insert one end of the magnet into the C-shaped clamp 3. Then, activate the first hydraulic rod 303, causing it to lower the pressure plate 304, thereby clamping one end of the magnet and ensuring the cutting part of the magnet is suspended. Next, drive the screw 103 to rotate via the drive motor 201. Since the screw 103 is threadedly connected to the threaded slider 302 at the lower end of the C-shaped clamp 3, the rotation of the screw 103 will cause the C-shaped clamp 3 and the magnet on it to slide along the linear guide rail 101, adjusting the magnet to a suitable cutting position. After adjustment, activate the second hydraulic rod 401, causing it to extend and push the clamping plate 402 to press tightly against the other side of the magnet, achieving double fixation of the magnet. At this time, the C-shaped clamp 3 has moved the magnet directly below the cutting line 504. Finally, the third hydraulic rod 501 is activated, causing the electrode box 502, its connecting frame 503, and the cutting wire 504 to descend. Simultaneously, the electrode box 502 generates a pulsed spark discharge, enabling the cutting wire 504 to precisely cut the magnet. Throughout the cutting process, the magnet is stably fixed, ensuring cutting accuracy and efficiency.
