Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnet processing technology, and in particular to a magnetizing device for magnet processing. Background Technology
[0002] In the field of magnet processing, magnetization is a key process for imparting stable magnetism to permanent magnet materials. The performance of the magnetization device directly affects the magnetization effect, production efficiency, and operational safety of the magnet.
[0003] Traditional magnetizing devices often have fixed clamping mechanisms that can only accommodate magnets of a single size. For smaller magnets, excessive clamping force can easily cause the magnetic material to break. For larger magnets, insufficient clamping stroke makes stable fixation impossible. Furthermore, the clamping action and the movement of the magnetizing cover are often independently controlled, requiring manual adjustment of the clamping position to ensure the magnet is in the strong magnetic field region of the magnetizing coil. This is not only cumbersome to operate, but also prone to uneven magnetization due to positioning deviations, resulting in problems such as localized weak magnetism and magnetic pole misalignment, which affects the product qualification rate. Utility Model Content

[0006] In one embodiment, a clamping block is detachably connected to the positioning block by bolts, the rack is slidably connected to the surface of the slider, a locking bolt is threaded onto the slider, one end of the locking bolt abuts against the square bar, and the end of the locking bolt near the square bar is provided with anti-slip texture.
[0007] In one embodiment, the top of the fixing frame is provided with a through groove corresponding to the square bar, the positioning grooves are symmetrically arranged on the top of the base plate, and each positioning groove is rotatably connected with a lead screw.
[0008] In one embodiment, the base plate is further provided with a discharge mechanism, which includes a first piston rod symmetrically arranged on the fixed frame and a second piston rod symmetrically arranged on the top of the base plate, the second piston rod being perpendicular to the fixed frame.
[0009] In one embodiment, the first piston rod and the second piston rod are connected by an oil pipe, and the first piston rod and the second piston rod are provided with corresponding hydraulic oil.
[0010] In one embodiment, a spring is fixedly connected between the telescopic end of the second piston rod and the surface of the second piston rod, and the telescopic end of the first piston rod is disposed in the slide groove and located directly above the slider.

[0013] Beneficial effects
[0014] 1. The magnetizing device for magnet processing described above has a rack on only the lower half of the square bar. With the help of locking bolts, the height of the square bar can be flexibly adjusted, thereby changing the meshing timing of the rack and gear. When clamping and fixing large magnets, the square bar is lowered to extend the clamping stroke of the positioning block; when clamping and fixing small magnets, the square bar is raised to shorten the clamping stroke, thus preventing the magnetic material from breaking. Moreover, the clamping mechanism is linked to the movement of the magnetizing cover, eliminating the need for manual adjustment of the positioning and ensuring that the magnet to be magnetized is always in the strong magnetic field area directly below the magnetizing cover, effectively avoiding the problem of uneven magnetization caused by positioning deviation.
[0015] 2. The material discharge mechanism does not require an additional independent power source. After magnetization is completed, the electric push rod drives the magnetization cover to move upward, and simultaneously drives the slider to move upward, squeezing the telescopic end of the first piston rod. This causes the hydraulic oil in the first piston rod to flow into the second piston rod through the oil pipe, driving the telescopic end of the second piston rod to extend and automatically push the magnetized magnet out of the clamping area, achieving rapid material discharge and improving production efficiency.

Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0025] The following is combined Figure 1 - Figure 5 This invention describes a magnetizing device for magnet processing.
[0026] In one embodiment, a magnetizing device for magnet processing includes: a base plate 100, with symmetrically arranged support legs 110 at the bottom of the base plate 100, a fixed frame 200 fixedly connected to the center of the top of the base plate 100, an electric push rod 210 fixedly mounted on the top of the fixed frame 200, and a magnetizing cover 220 fixedly connected to the telescopic end of the electric push rod 210; and a clamping mechanism 300 disposed on the fixed frame 200, the clamping mechanism 300 including sliding grooves 310 formed on both sides of the fixed frame 200. A slider 320 is slidably connected inside the groove 310. The slider 320 is fixedly connected to the magnetizing cover 220. A square bar 330 is installed on the slider 320. A rack 340 is provided at the lower position of the surface of the square bar 330. A positioning groove 360 is opened at the top of the base plate 100. A lead screw 370 is rotatably connected inside the positioning groove 360. A positioning block 380 that meshes with the positioning groove 360 is slidably connected inside the positioning groove 360. A gear 350 that meshes with the rack 340 is fixedly connected to one end of the lead screw 370.
[0027] like Figure 1 , Figure 3 and Figure 5 As shown, a clamping block is detachably connected to the positioning block 380 by bolts. A rack 340 is slidably connected to the surface of the slider 320. A locking bolt 390 is threaded onto the slider 320. One end of the locking bolt 390 abuts against the square bar 330, and the end of the locking bolt 390 near the square bar 330 has anti-slip textures. The top of the fixing frame 200 has a through groove corresponding to the square bar 330. Positioning grooves 360 are symmetrically arranged on the top of the base plate 100, and a lead screw 370 is rotatably connected to each positioning groove 360. An arc-shaped groove is provided on the side of the clamping block away from the positioning block 380. A rubber pad is pasted in the arc-shaped groove, and the surface of the rubber pad has anti-slip ridges.
[0028] In this embodiment, the clamping block is detachably connected to the positioning block 380 by bolts, facilitating the replacement of suitable clamping blocks according to the shape and size of the magnet, thus improving the device's adaptability to magnets of different specifications. The anti-slip texture on one end of the locking bolt 390 enhances the friction with the square bar 330, ensuring stable fixation of the square bar 330 after height adjustment and preventing displacement of the square bar 330 during magnetization, which would affect clamping accuracy. The through slot at the top of the fixing frame 200 provides vertical movement space for the square bar 330, preventing interference between the square bar 330 and the fixing frame 200. The arc-shaped groove on the clamping block is adapted to cylindrical magnets, the rubber pad prevents damage to the magnet surface during clamping, and the anti-slip texture further improves clamping stability, preventing the magnet from sliding during magnetization and ensuring magnetization stability. The model and size of the clamping block can be selected as needed.
[0029] It should be noted that the magnetizing cover 220, as the core magnetizing component of the device, is not a single shell structure; it integrates a magnetizing coil, wiring terminals, and a heat insulation layer.
[0030] Magnetizing coil: It is made of multiple turns of high-strength enameled copper wire. The shape of the coil is adapted to the shape of the magnet to be magnetized. The central area of the coil is the area of strong magnetic field action, which is the core position when the magnet is magnetized.
[0031] Terminal blocks: located on the side wall of the magnetizing cover 220, connected to an external magnetizing power supply via wires, used to receive instantaneous large currents;
[0032] Heat insulation protective layer: Wrapped around the outside of the magnetizing coil. Because the coil will generate instantaneous heat during magnetization, the protective layer can prevent the heat from being conducted to the magnetizing cover 220 housing and surrounding components, and at the same time prevent operators from being burned by contact.
[0033] like Figure 1 , Figure 2 and Figure 4 As shown, a discharge mechanism 400 is also provided on the base plate 100. The discharge mechanism 400 includes a first piston rod 410 symmetrically arranged on the fixed frame 200, and a second piston rod 420 symmetrically arranged on the top of the base plate 100. The second piston rod 420 is perpendicular to the fixed frame 200. The first piston rod 410 and the second piston rod 420 are connected by an oil pipe, and corresponding hydraulic oil is provided in the first piston rod 410 and the second piston rod 420. A spring 430 is fixedly connected between the telescopic end of the second piston rod 420 and the surface of the second piston rod 420. The telescopic end of the first piston rod 410 is located in the slide groove 310 and is directly above the slider 320. A pedal switch electrically connected to the magnetizing cover 220 is provided at the bottom of the base plate 100.
[0034] In this embodiment, the first piston rod 410 and the second piston rod 420 are connected by an oil pipe to form a hydraulic circuit, ensuring smooth flow of hydraulic oil for power transmission. The spring 430 can pull the telescopic end of the second piston rod 420 back to its original position after discharge, preparing for the next discharge without requiring an additional power source. The telescopic end of the first piston rod 410 is located directly above the slider 320, ensuring that the slider 320 accurately squeezes the first piston rod 410 when it moves upward, triggering the discharge action and expelling the magnetized magnets. A foot pedal switch at the bottom of the base plate 100 allows operators to easily control the magnetization cover 220 with their feet, freeing their hands and improving operational convenience and safety.
[0035] Working principle: First, according to the size of the magnet to be magnetized, loosen the locking bolt 390, move the square bar 330 up and down to adjust the initial position of the rack 340, and after adjustment, tighten the locking bolt 390 to fix the square bar 330. Place the magnet to be magnetized between the two clamping blocks, and the operator steps on the pedal switch to start the electric push rod 210. The telescopic end of the electric push rod 210 drives the magnetizing cover 220 and the slider 320 to move downward along the slide groove 310. The downward movement of the slider 320 drives the square bar 330 to move downward synchronously. When the rack 340 on the square bar 330 meshes with the gear 350, the downward movement of the rack 340 is converted into the rotational movement of the gear 350. The gear 350 drives the lead screw 370 to rotate in the positioning groove 360. The rotation of the lead screw 370 drives the positioning block 380 to move towards each other along the positioning groove 360, clamping the magnet through the clamping blocks.
[0036] As the electric push rod 210 continues to extend, the magnetizing cover 220 moves further down. At this time, the part of the square bar 330 without the rack 340 moves to the gear 350, the rack 340 disengages from the gear 350, the positioning block 380 stops moving, the magnet remains in a stable clamped state, and the magnetizing operation begins after the magnetizing cover 220 moves to the appropriate position.
[0037] After magnetization is complete, the telescopic end of the electric push rod 210 drives the magnetizing cover 220 and the slider 320 to move upward. The upward movement of the slider 320 drives the square bar 330 to move upward. The rack 340 and gear 350 mesh in opposite directions, driving the lead screw 370 to rotate in the opposite direction. The positioning blocks 380 move in opposite directions, and the clamping blocks are released. At this time, during the upward movement of the slider 320, the telescopic end of the first piston rod 410 is squeezed, forcing the hydraulic oil in the first piston rod 410 into the oil pipe. The hydraulic oil flows into the second piston rod 420 through the oil pipe, pushing the telescopic end of the second piston rod 420 to extend, pushing the magnetized magnet out from between the clamping blocks, completing the discharge. When magnetization is performed again, the telescopic end of the second piston rod 420 is reset under the tension of the spring 430, and the hydraulic oil resets the telescopic end of the first piston rod 410, waiting for magnetization.
[0038] It should be noted that the electric push rod 210, magnetizing cover 220, first piston rod 410, and second piston rod 420 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the electric push rod 210 and magnetizing cover 220 can be powered by mains power. The specific power supply method can be selected according to the situation, which will not be elaborated here.
[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
