Description
Technical Field
[0001] This utility model relates to the field of soft magnetic material processing technology, specifically a soft magnetic material cutting debris recycling device. Background Technology
[0002] Soft magnetic materials often contain high-value metals or special components: such as silicon steel sheets (high-quality steel containing 3%-5% silicon, used in motor cores), permalloy (a precious metal alloy containing 30%-80% nickel, used in high-precision sensors), and ferrites (containing functional components such as iron oxide and zinc oxide). These materials have high raw material procurement costs. Even if the fragments produced after cutting are not destroyed, their core components can still be crushed, purified, remelted, and pressed to reconstitute soft magnetic blanks or low-specification soft magnetic components, such as small transformer cores and toy motor cores, thus avoiding waste of raw materials.
[0003] Based on the above, the inventors have discovered the following problems: In current soft magnetic material cutting and processing, the generated debris generally contains a mixture of different materials such as silicon steel sheets, permalloy, and ferrite. If these mixed debris are directly recycled, they cannot directly enter the remelting or reprocessing process due to the significant differences in the composition and magnetic properties of different soft magnetic materials. Otherwise, it will lead to the deterioration of the performance of the reused finished product. For example, silicon steel sheet debris mixed with permalloy will reduce the high-precision magnetic sensing performance of permalloy; ferrite mixed with silicon steel sheets will increase the loss of the motor core. The recycling process must rely on manual sorting. Workers need to use magnets to adsorb and judge the difference in coercivity to separate the debris of different materials one by one, thereby reducing the recycling efficiency.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a soft magnetic material cutting debris recycling device in order to achieve a more practical purpose. Utility Model Content
[0005] The purpose of this invention is to provide a soft magnetic material cutting debris recycling device to solve the problems mentioned in the background art.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A soft magnetic material cutting debris recycling device includes a drive assembly and a separation assembly. The separation assembly includes a first half-cylinder, a second half-cylinder at the bottom of the first half-cylinder, and first half-magnetic rings mounted opposite each other on the inner walls of both the first and second half-cylinders. Second half-magnetic rings are also mounted opposite each other on the inner walls of both the first and second half-cylinders on the side of the first half-magnetic rings, and third half-magnetic rings are mounted opposite each other on the inner walls of both the first and second half-cylinders on the side of the second half-magnetic rings. The magnetic properties of the first half-magnetic rings are less than those of the second half-magnetic rings, and the magnetic properties of the second half-magnetic rings are less than those of the third half-magnetic rings. Split flanges are installed at both ends of the first and second half-cylinders. A feed inlet is provided at one end of each of the first and second half-cylinders, and a vacuum pump is provided at the end of each half-cylinder away from the feed inlet.
[0007] Furthermore, a pair of first connecting seats are installed on the outer wall of the first half-cylinder, and a second connecting seat is installed on the outer wall of the second half-cylinder opposite to the pair of first connecting seats. Bolts are threadedly connected between the opposing first connecting seats and the second connecting seats.
[0008] The beneficial effects of adopting the above-mentioned further solution are that, through the cooperation of the first connecting seat, the second connecting seat and the bolt, the first half-cylinder and the second half-cylinder can be quickly spliced and tightly fixed, and the threaded connection of the bolt can provide a stable locking force; at the same time, the detachability of the threaded connection makes it convenient to clean the soft magnetic cutting material adsorbed by the first half-magnetic ring, the second half-magnetic ring and the third half-magnetic ring in the first half-cylinder and the second half-cylinder in the later stage, or to disassemble the half-cylinder for maintenance as needed, thereby improving the convenience of equipment maintenance.
[0009] Furthermore, the drive assembly includes two first half-circles, which are respectively installed on the outer walls of both ends of the first half-cylinder. A second half-circle is hinged to one side of the bottom end of each of the two first half-circles, and the two second half-circles are respectively installed on the outer walls of both ends of the second half-cylinder.
[0010] The beneficial effect of adopting the above-mentioned further solution is that the hinge structure of the first half-circle and the second half-circle provides a stable rotation fulcrum for the opening and closing of the first half-cylinder and the second half-cylinder, so that the first half-cylinder and the second half-cylinder can rotate smoothly around the hinge axis and realize the switching of opening and closing operations.
[0011] Furthermore, each of the two first half-circles has a first groove inside, each of the two second half-circles has a second groove inside, each of the two second grooves has a slide bar inside, and each of the two slide bars has a connecting plate installed at its bottom end. The outer wall of the slide bar slides in cooperation with the inner wall of the first and second grooves.
[0012] The beneficial effect of adopting the above-mentioned further solution is that the slider can slide in the first and second slide grooves, providing guidance and limiting function for the rotation of the overall structure of the first and second half-cylinders.
[0013] Furthermore, the drive assembly also includes a pair of upright plates, each of which has a reinforcing seat mounted on its opposite side, and the top surfaces of the two reinforcing seats are respectively fixedly connected to the bottom ends of the two connecting plates.
[0014] The beneficial effect of adopting the above-mentioned further solution is that the upright plate, as a supporting foundation, is connected to the connecting plate through the reinforcing seat, providing an installation carrier for the slide bar.
[0015] Furthermore, each of the two upright plates has an annular guide rail installed on its opposite side, and guide rail sliders are slidably connected to the outside of the two annular guide rails. The opposite sides of the two guide rail sliders are respectively fixedly connected to the outer walls of the two second half rings.
[0016] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the annular guide rail and the guide rail slider, a circumferential motion guide is provided for the second half-circle and the connected second half-cylinder, so that the closed first half-cylinder and the second half-cylinder as a whole move in a circular motion under the action of the slide bar, so that the soft magnetic cutting material in the closed first half-cylinder and the second half-cylinder is uniformly attracted by the first half magnetic ring, the second half magnetic ring and the third magnetic ring respectively.
[0017] Furthermore, a stainless steel filter screen is installed inside the air inlet of the air pump.
[0018] The beneficial effects of adopting the above-mentioned further solution are that the stainless steel filter can effectively intercept fine soft magnetic debris (especially powdered ferrite debris) that enters the air pump with the airflow, preventing debris from entering the air pump and wearing the impeller and clogging the air passage, thereby protecting the air pump and extending its service life; the filter is made of stainless steel, which has the characteristics of rust resistance and high strength, and can adapt to dust and slight moisture in the debris recycling environment.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: In this soft magnetic material cutting debris recycling device, when the split flange closes under the action of the first and second half-cylinders to form a complete flange ring, a pipe connects the debris conveying channel of the cutting equipment to the air inlet. Then, the flange at the air inlet end of the suction pump is connected to the complete flange ring located away from the air inlet. The suction pump is then started, causing the debris to enter the closed first and second cylinders. Subsequently, because the magnetism of the first half-magnetic ring is less than that of the second half-magnetic ring, and the magnetism of the second half-magnetic ring is less than that of the third half-magnetic ring, the first half-magnetic ring... The first half of the magnetic ring is weakly magnetic, the second half is moderately magnetic, and the third half is strongly magnetic, thus forming a gradient magnetic field from weak to strong. This matches the magnetic characteristics of ferrite (low coercivity), silicon steel (medium coercivity), and permalloy (high coercivity). Ferrite debris is adsorbed in the weak magnetic region of the first half of the magnetic ring, silicon steel debris is adsorbed in the moderate magnetic region of the second half of the magnetic ring, and permalloy debris is adsorbed in the strong magnetic region of the third half of the magnetic ring. This achieves the physical separation of soft magnetic debris of three different materials without manual intervention, solving the problem of difficulty in separating mixed materials during recycling.

[0022] 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.
[0023] Please see Figures 1-5 This utility model provides a technical solution: a soft magnetic material cutting debris recycling device, including a driving component 1 and a separation component 2. The separation component 2 includes a first half-cylinder 21, a second half-cylinder 22 at the bottom end of the first half-cylinder 21, and first half-magnetic rings 23 mounted opposite each other on the inner walls of both the first half-cylinder 21 and the second half-cylinder 22. Second half-magnetic rings 24 are mounted opposite each other on the inner walls of both the first half-cylinder 21 and the second half-cylinder 22 on the side of the first half-magnetic ring 23. Third half-magnetic rings 25 are mounted opposite each other on the inner walls of both the first half-cylinder 21 and the second half-cylinder 22 on the side of the second half-magnetic ring 24. The magnetism of ring 23 is less than that of the second half-magnetic ring 24, and the magnetism of the second half-magnetic ring 24 is less than that of the third half-magnetic ring 25. Both ends of the first half-cylinder 21 and the second half-cylinder 22 are equipped with split flanges. A feed inlet is provided at one end of each half-cylinder 21 and the second half-cylinder 22. A vacuum pump 3 is provided at the end of each half-cylinder 21 and the half-cylinder 22 furthest from the feed inlet. A pair of first connecting seats 26 are installed on the outer wall of the first half-cylinder 21, and a second connecting seat 27 is installed on the outer wall of the second half-cylinder 22 opposite to the pair of first connecting seats 26. The opposing first connecting seats 26 and second connecting seats 27 are connected by screws. The flange is connected by bolts 28. When the split flange closes under the action of the first half-cylinder 21 and the second half-cylinder 22 to form a complete flange ring, the chip conveying channel of the cutting equipment and the air inlet are connected by a pipeline. Then, the flange at the air inlet end of the suction pump 3 is connected to the complete flange ring away from the air inlet. The suction pump 3 is started to allow the chips to enter the interior of the closed first and second cylinders. Since the magnetism of the first half-magnetic ring 23 is less than that of the second half-magnetic ring 24, and the magnetism of the second half-magnetic ring 24 is less than that of the third half-magnetic ring 25, the first half-magnetic ring 23 is weakly magnetic, the second half-magnetic ring 24 is moderately magnetic, and the third half-magnetic ring 25 is strongly magnetic. The magnetism creates a gradient magnetic field from weak to strong, matching the low coercivity of ferrite, the medium coercivity of silicon steel sheets, and the high coercivity of permalloy. Ferrite debris is attracted in the weak magnetic region of the first half-magnetic ring 23, silicon steel sheet debris is attracted in the medium magnetic region of the second half-magnetic ring 24, and permalloy debris is attracted in the strong magnetic region of the third half-magnetic ring 25, thus achieving physical separation of soft magnetic debris of three different materials. When the first half-cylinder 21 and the second half-cylinder 22 are closed, they are locked and fixed by bolts 28. When the locking bolts 28 are loosened and removed, the first half-cylinder 21 and the second half-cylinder 22 can be opened.
[0024] 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.
[0025] Please see Figures 1-5 This utility model provides a technical solution: the drive assembly 1 includes two first semicircles 11, which are respectively installed on the outer walls of both ends of the first semi-cylinder 21. A second semicircle 12 is hinged to one side of the bottom end of each of the two first semicircles 11, and the two second semicircles 12 are respectively installed on the outer walls of both ends of the second semi-cylinder 22. A first groove 13 is formed inside each of the two first semicircles 11, and a second groove 14 is formed inside each of the two second semicircles 12. A slide bar 15 is provided inside each of the two second grooves 14, and a connecting plate 16 is installed at the bottom end of each of the two slide bars 15. The outer wall of the slide bar 15 slides in cooperation with the inner wall of the first groove 13 and the second groove 14. The drive assembly 1 also includes a pair of upright plates 17, each with a reinforcing seat installed on its opposite side. The top surfaces of the two reinforcing seats are respectively connected to the two connecting plates 17. The bottom end of 6 is fixedly connected, and a pair of upright plates 17 are each equipped with annular guide rails 18 on their opposite sides. Guide rail sliders 19 are slidably connected to the outside of the two annular guide rails 18. The opposite sides of the two guide rail sliders 19 are respectively fixedly connected to the outer walls of the two second half-circles 12. A stainless steel filter screen is installed inside the air inlet end of the air pump 3. Through the cooperation of the annular guide rails 18 and guide rail sliders 19, circumferential motion guidance is provided for the second half-circle 12 and the connected second half-cylinder 22, so that the closed first half-cylinder 21 and the second half-cylinder 22 move in a circular motion under the action of the slide bar 15, so that the soft magnetic cutting material in the closed first half-cylinder 21 and the second half-cylinder 22 is evenly attracted by the first half-magnetic ring 23, the second half-magnetic ring 24, and the third magnetic ring respectively. The two annular guide rails 18 drive the two guide rail sliders 19 to move in the same direction and at the same speed.
[0026] Specifically, the working principle of this soft magnetic material cutting debris recycling device is as follows: During use, when the split flange closes under the action of the first half-cylinder 21 and the second half-cylinder 22 to form a complete flange ring, a pipe connects the debris conveying channel of the cutting equipment to the air inlet. Then, the flange at the air inlet end of the suction pump 3 is connected to the complete flange ring located away from the air inlet. The suction pump 3 is then started, causing the debris to enter the closed first and second cylinders. Because the magnetism of the first half-magnetic ring 23 is less than that of the second half-magnetic ring 24, and the magnetism of the second half-magnetic ring 24 is less than that of the third half-magnetic ring 25, the first half-magnetic ring 23 is weakly magnetic, the second half-magnetic ring 24 is moderately magnetic, and the third half-magnetic ring 25 is strongly magnetic, thus forming a gradient magnetic field from weak to strong. This matches the low coercivity of ferrite, the moderate coercivity of silicon steel sheets, and the high coercivity of permalloy. The ferrite debris is then adsorbed in the weak magnetic region of the first half-magnetic ring 23. Silicon steel sheet fragments are adsorbed in the magnetic region of the second half-magnetic ring 24, while permalloy fragments are adsorbed in the strong magnetic region of the third half-magnetic ring 25, achieving physical separation of the three different soft magnetic fragments. Through the cooperation of the annular guide rail 18 and the guide rail slider 19, circumferential movement guidance is provided for the second half-ring 12 and the connected second half-cylinder 22, so that the closed first half-cylinder 21 and the second half-cylinder 22 move in a circular motion under the action of the slider 15, so that the soft magnetic cutting material in the closed first half-cylinder 21 and the second half-cylinder 22 is evenly adsorbed by the first half-magnetic ring 23, the second half-magnetic ring 24, and the third magnetic ring respectively. After separation, the locking bolt 28 is loosened and removed, making it easy to open the first half-cylinder 21 and the second half-cylinder 22. The soft magnetic cutting material of different materials on the inner wall of the first half-magnetic ring 23, the second half-magnetic ring 24, and the third half-magnetic ring 25 can be scraped off using tools such as scrapers.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. Furthermore, since this application is mainly used to protect mechanical devices, the control methods and circuit connections will not be explained in detail in this application.
