Description

Technical Field

[0001] This invention relates to the field of soft magnetic powder preparation technology, and in particular to a powder collection device used in pressing equipment. Background Technology

[0002] Soft magnetic powder compression molding is a process in which soft magnetic powder that has undergone insulation coating is compressed into shape under pressure according to a certain ratio.

[0003] In existing technologies, during the pressing of soft magnetic powder, a feeding mechanism is typically used to transport the powder into a pressing groove on a mold. To ensure that the powder is evenly layered to a certain thickness within the pressing groove, the discharge end of the feeding mechanism is often tightly fitted to the mold surface and reciprocated along the length of the mold. When the discharge end of the feeding mechanism moves from the area outside the pressing groove on the mold surface to above the pressing groove, the powder can smoothly fall from the feeding mechanism into the pressing groove. Since the feeding mechanism is in motion, the powder will evenly spread within the pressing groove along the direction of its movement.

[0004] However, when the discharge end of the feeding mechanism is in contact with the non-pressing groove area on the mold surface, the flatness of the mold surface or the discharge end of the feeding mechanism cannot be ideal, and there will be unevenness. At this time, during the movement of the discharge end of the feeding mechanism, some powder will leak from the contact area between the feeding mechanism and the mold, and some powder will remain on the surface of the mold or the discharge end of the feeding mechanism. If these powders cannot be recovered in time, not only will some soft magnetic powder be wasted, but the feeding process of the feeding mechanism may also be affected. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a powder collection device for use in pressing equipment, which aims to solve the problems of soft magnetic powder leakage and residue in the prior art.

[0006] This invention provides a powder collection device for use in a pressing equipment. The pressing equipment includes a press, a mold, and a feeding mechanism. The mold is mounted on the press and has a pressing groove. The powder collection device includes a translation mechanism, a powder scraping and adsorption component, and a negative pressure storage device. The translation mechanism moves horizontally along the length of the mold, and one end of the feeding mechanism is fixedly connected to the translation mechanism. The powder scraping and adsorption component is mounted on the translation mechanism and has pushing parts located at both ends of the feeding mechanism's moving direction. Each pushing part has a receiving chamber with an opening facing the mold. The mold, the translation mechanism, and the pushing parts form a relatively closed space. The pushing parts scrape powder from the mold surface and push it into the receiving chamber during movement. The discharge end of the feeding mechanism extends into the relatively closed space in a sealed manner. The size of the discharge end of the feeding mechanism is adapted to the pressing groove and fits against the surface of the mold. The negative pressure storage device is connected to the receiving chamber and generates negative pressure to adsorb and store the powder at the opening of the receiving chamber.

[0007] In addition, the powder collection device applied in a pressing device according to the present invention may also have the following additional technical features:

[0008] Furthermore, the mold includes a template and a protective plate. The template has an inwardly recessed pressing groove on one side of its surface facing the discharge end of the feeding mechanism. The protective plate is arranged around the periphery of the template. The translation mechanism includes a frame plate and a cover plate. The mold is set in the inner cavity of the frame plate. The cover plate is located above the protective plate and is movably connected to the frame plate to move horizontally along the length of the template. The powder scraping and adsorption assembly includes a first hose and a powder scraping box. The powder scraping box is hollow inside to form a receiving chamber. The powder scraping box is located between the cover plate and the template. One end of the powder scraping box is fixed to the cover plate, and the other end of the powder scraping box is open with the edge of the opening abutting against the surface of the template. The powder scraping box abuts against the protective plate on both sides along the width direction of the template. One end of the first hose is sealed through the cover plate and communicates with the receiving chamber. The other end of the first hose is sealed and connected to the negative pressure storage device.

[0009] Furthermore, the negative pressure reservoir includes an upper tank, a lower tank, a filter assembly, and a vacuum generator. The upper tank is detachably connected to the lower tank. The filter assembly is used to divide the internal space of the upper tank into a first region and a second region. The first region is close to the lower tank. The negative pressure port of the vacuum generator is connected to the second region. The first hose is connected to the first region inside the upper tank.

[0010] Furthermore, the filter assembly includes a frame and a mesh bag. A cap is provided on the upper barrel, the frame is set on the cap and extends into a second area inside the upper barrel, the periphery of the mesh bag is pressed by the cap, and the middle of the mesh bag is opened by the frame.

[0011] Furthermore, a partition is also provided in the first area. The partition is funnel-shaped and has a discharge port in the middle. The connection port between the first hose and the upper tank is located below the partition, and the filter assembly is located above the partition.

[0012] Furthermore, the translation mechanism also includes a driving component, which is mounted on the side plate and is connected to the cover plate in a transmission manner.

[0013] Furthermore, the feeding mechanism includes a second hose and a funnel head. One end of the second hose is used to connect to the feeding device, and the other end of the second hose is connected to the funnel head. The funnel head passes through the cover plate and is fixed on the cover plate. The outlet of the funnel head is provided with a baffle, which abuts against the surface of the template.

[0014] Furthermore, the powder collection device used in the pressing equipment also includes a vibration device. The vibration device includes a housing and a turntable. The housing has a receiving cavity that can accommodate the rotation of the turntable. The receiving cavity is connected in series with a first flexible tube, and the first flexible tube is arranged around the edge of the receiving cavity. The circumferential edge of the turntable is provided with striking elements at intervals. The striking elements are rotatably arranged on the turntable. The edge of the receiving cavity and the striking elements are both made of soft material. The first flexible tube arranged around the edge of the receiving cavity squeezes the striking elements and contacts the second flexible tube.

[0015] Furthermore, the first hose is provided with rubber protrusions, which are in contact with the surface of the second hose.

[0016] Furthermore, the negative pressure storage device also includes a support assembly, which includes a first support and a second support. The second support is slidably mounted on the first support, the lower bucket is rotatably mounted on the first support, and the upper bucket is fixed on the second support. A spring is also provided between the first support and the second support. A handle is provided on the second support, and a roller is provided at the bottom of the first support.

[0017] The beneficial effects of the present invention include at least the following: the powder is evenly spread in the pressing groove by the translation mechanism, and the sealed space can prevent the powder from drifting and leaking in the workplace. In addition, the powder residue on the mold surface can be effectively collected by the powder scraping and adsorption component and the negative pressure storage device. Moreover, in the non-pressing groove area on the mold surface, the powder scraping and adsorption component can adsorb the powder as the translation mechanism reciprocates, so that the newly residual powder on the mold surface can be adsorbed in a timely manner.

[0028] The following detailed description, in conjunction with the accompanying drawings, will further illustrate the present invention. Detailed Implementation

[0029] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] reference Figure 1-8This invention provides a powder collection device for use in a pressing device. The pressing device typically includes a press 100, a mold 200, and a feeding mechanism 300. The mold 200 is mounted on the working position of the press 100, and a pressing groove 210 is provided on its surface. When pressing magnetic powder cores, a certain thickness of magnetic powder is first laid in the pressing groove 210, and then the powerful pressing force of the press 100 is used to shape the magnetic powder. The powder collection device includes a translation mechanism 400, a powder scraping and adsorption component 500, and a negative pressure storage device 600. During powder spreading, the translation mechanism 400 moves horizontally back and forth along the length of the mold 200. One end of the feeding mechanism 300 is fixedly connected to the translation mechanism 400, so that the feeding mechanism 300 can move horizontally back and forth with the translation mechanism 400, achieving uniform powder spreading within the pressing groove 210. The powder scraping and adsorption component 500 is also mounted on the translation mechanism 400, so that the powder scraping and adsorption component 500 can also move horizontally with the translation mechanism 400. The powder scraping and adsorption assembly 500 is provided with a pushing part, which is located at both ends of the feeding mechanism 300 in the moving direction. The pushing part has a receiving chamber 510, which is open at one end facing the mold 200. The mold 200, the translation mechanism 400, and the pushing part form a relatively closed space 700. The pushing part is used to scrape the powder on the surface of the mold 200 and push it into the receiving chamber during movement. The discharge end of the feeding mechanism 300 extends into the closed space 700 in a sealed manner. The size of the discharge end of the feeding mechanism 300 is adapted to the pressing groove 210 and the mold... The surface of the feeding mechanism 300 is in contact with the mold 200. This ensures that the powder within the feeding mechanism 300 will only fall into the pressing groove 210 when the discharge end of the feeding mechanism 300 overlaps with the area of ​​the pressing groove 210. When it does not overlap, the powder cannot escape from the feeding mechanism 300 because the discharge end of the feeding mechanism 300 is in contact with the surface of the mold 200. Furthermore, since the discharge end of the feeding mechanism 300 moves horizontally back and forth, the overlapping area first increases linearly and then decreases linearly until the discharge end of the feeding mechanism 300 is completely in contact with the surface of the mold 200. During the movement, although the powder cannot escape from the feeding mechanism 300, the surface of the mold 200 is not ideally smooth; many rough areas appear. In this case, the powder within the feeding mechanism 300 will remain in these rough areas. To this end, by setting pusher parts on both sides of the moving direction of the feeding mechanism 300 and connecting the negative pressure storage 600 to the receiving chamber 510, the negative pressure storage 600 is used to generate negative pressure. During the movement of the pusher parts, the surface of the mold 200 is scraped. At this time, some powder is pushed to the edge of the bottom opening of the receiving chamber 510. Under the action of negative pressure, these powders are adsorbed into the inside of the receiving chamber 510 and finally flowed back into the negative pressure storage 600 for storage. It can be understood that since some powders are not deeply adhered to the surface of the mold 200, scraping is not required. Instead, they are directly sucked into the inside of the receiving chamber 510 under the action of negative pressure.

[0032] In some alternative embodiments, such as Figure 2-4 As shown, the mold 200 includes a template 220 and a guard plate 230. The surface of the template 220 facing the discharge end of the feeding mechanism 300 is recessed inward to form a pressing groove 210, corresponding to the upper side of the template 220 in the attached figure. The guard plate 230 is arranged around the four edges of the upper surface of the template 220, thereby forming a rectangular working area on the upper surface of the template 220. The translation mechanism 400 includes a frame plate 410 and a cover plate 420. The frame plate 410 is fixedly installed on the working position of the press 100. The mold 200 is placed entirely in the inner cavity in the middle of the frame plate 410. The cover plate 420 is mounted on the guard plate 230 and is movably connected to the frame plate 410 to move horizontally back and forth along the length direction of the template 220. Specifically, to achieve the movable connection between the cover plate 420 and the frame plate 410, sliders can be set on the left and right sides of the lower surface of the cover plate 420, and corresponding guide rails can be set on the frame plate 410. By aligning the sliders with the guide rails, the cover plate 420 can slide horizontally back and forth on the frame plate 410. The powder scraping and adsorption assembly 500 includes a first flexible tube 520 and a powder scraping box 530. The powder scraping box 530 is located within the rectangular working area formed on the upper surface of the template 220, and the powder scraping box 530 is located at both ends of the cover plate 420 in the direction of movement. The powder scraper box 530 is hollow inside to form a receiving chamber 510. The powder scraper box 530 is located between the cover plate 420 and the template 220, and the upper end of the powder scraper box 530 is fixedly installed on the cover plate 420. The lower end of the powder scraper box 530 is open and the edge of the opening abuts against the surface of the template 220. The left and right sides of the two powder scraper boxes 530 abut against the guard plate 230. In this way, a relatively closed space 700 is formed between the powder scraper box 530, the guard plate 230, the template 220, and the cover plate 420. The discharge end of the feeding mechanism 300 extends into the closed space 700. In this way, when the discharge end of the feeding mechanism 300 does not completely overlap with the area where the pressing groove 210 is located, even if some powder is blown out from the pressing groove 210, it will only be confined within the closed space 700 and will not pollute the surrounding environment. Furthermore, one end of the first flexible tube 520 is sealed and passes through the cover plate 420 and communicates with the receiving chamber 510, while the other end of the first flexible tube 520 is sealed and connected to the negative pressure storage device 600. During the movement of the powder scraper box 530 driven by the translation mechanism 400, to prevent the powder scraper box 530 from adsorbing and carrying away powder when passing through the pressing groove 210, the negative pressure storage device 600 can be temporarily controlled to stop generating negative pressure. Alternatively, an opening and closing device such as a solenoid valve can be installed on the first flexible tube 520 to prevent airflow from the first flexible tube 520. The timing of opening and closing can be determined based on the distance between the powder scraper box 530 and the pressing groove 210, as well as the size of the pressing groove 210.

[0033] In some alternative embodiments, such as Figure 5-7As shown, the negative pressure reservoir 600 includes an upper tank 610, a lower tank 620, a filter assembly 630, and a vacuum generator 640. The upper tank 610 is detachably connected to the lower tank 620. The filter assembly 630 divides the internal space of the upper tank 610 into a first region 611 and a second region 612. The first region 611 corresponds to the lower region of the upper tank 610, and the second region 612 corresponds to the upper region of the lower tank 610. The vacuum generator 640 is located outside the upper tank 610 and the lower tank 620. Specifically, the vacuum generator 640 can be installed and fixed to the upper tank 610, the lower tank 620, or independently on a fixed support device. Preferably, the vacuum generator 640 is installed and fixed to the upper tank 610. In this case, the negative pressure port of the vacuum generator 640 is connected to the second region 612 of the upper tank 610, and the first flexible hose 520 is connected to the first region 611 inside the upper tank 610.

[0034] In this embodiment, after the vacuum generator 640 is activated, it generates negative pressure. The airflow carrying the powder flows sequentially through the receiving chamber 510, the first hose 520, and the first region 611. The powder is filtered at the filter assembly 630 and trapped. Under the influence of gravity, the powder falls into the lower container 620. The airflow without powder flows through the filter assembly 630, and then flows through the second region 612 before entering the vacuum generator 640. When these powders are needed, only the powder stored in the lower container 620 needs to be transferred away.

[0035] In some alternative embodiments, such as Figure 6 , 7 As shown, the filter assembly 630 includes a frame 631 and a mesh bag (not shown in the figures). The top of the upper barrel 610 is provided with a cover 613. The frame 631 is installed and fixed on the cover 613, and the frame 631 extends downward into the second region 612 inside the upper barrel 610. The periphery of the mesh bag is pressed by the cover 613, and the middle part of the mesh bag is located inside the upper barrel 610 and fixed on the frame 631. The frame 631 presents a scattering state as a whole, and its size increases from top to bottom. Under the limiting action of the frame 631, the mesh bag is opened, thereby forming a contact surface that can intercept powder. The negative pressure port of the vacuum generator 640 is connected to the cover 613. In this embodiment, because the periphery of the mesh bag is pressed against the cap 613, powder cannot enter the vacuum generator 640. Simultaneously, the frame 631 fully expands the mesh bag, giving it a large interception area, effectively intercepting a large amount of powder and preventing powder from accumulating on the mesh bag. This allows the powder to fall smoothly into the lower container 620 under gravity. Furthermore, when it is necessary to replace the mesh bag or clean the internal space of the upper container 610, simply open the cap 613 and perform the corresponding operation through the opening on the upper container 610 corresponding to the cap 613.

[0036] In some alternative embodiments, such as Figure 7 As shown, a partition 650 is also provided in the first area 611. The partition 650 is funnel-shaped with its opening facing upward. A discharge port 651 is provided in the middle of the partition 650. The connection port between the first hose 520 and the upper tank 610 is located below the partition 650, and the filter assembly 630 is located above the partition 650. In this embodiment, since the connection port between the first hose 520 and the upper bucket 610 is located below the partition 650, when the airflow carrying powder from the first hose 520 hits the partition 650, some of the powder will lose kinetic energy and fall into the lower bucket 620. The remaining gas carrying powder enters at a reduced speed due to the obstruction of the partition 650, and then flows upward from the discharge port 651. When passing through the mesh bag, the powder in the gas is intercepted and falls downward under the action of gravity. Since the partition 650 is funnel-shaped, the powder falling on the partition 650 can smoothly fall into the lower bucket 620 from the discharge port 651 along the slope of the partition 650.

[0037] To control the horizontal reciprocating movement of the translation mechanism 400, in some optional embodiments, such as Figure 2 , 3 As shown, the translation mechanism 400 also includes a drive component 430, which is mounted on the frame plate 410 and is connected to the cover plate 420 via a transmission connection. Optionally, the drive component 430 can be a linear motor or a cylinder. Preferably, the drive component 430 is a cylinder, with the piston rod at the front end of the cylinder fixed to the cover plate 420. When the piston rod extends or retracts, it drives the cover plate 420 to move on the frame plate 410. Moreover, it is convenient to install a displacement sensor on the cylinder, which can measure the piston rod stroke in real time. Based on the piston rod stroke, the negative pressure reservoir 600 can be controlled to stop generating negative pressure and the timing of generating negative pressure, or the timing of opening and closing the first hose 520 can be controlled, to prevent the powder scraper box 530 from adsorbing and carrying away powder when it passes through the pressing groove 210 during the movement of the translation mechanism 400 driving the powder scraper box 530.

[0038] In some alternative embodiments, such as Figure 2 , 3As shown, the feeding mechanism 300 includes a second flexible hose 310 and a funnel head 320. One end of the second flexible hose 310 is connected to a feeding device, and the other end is connected to the funnel head 320. The funnel head 320 passes through the upper surface of the cover plate 420 and is fixed to the cover plate 420. A baffle 321 is provided around the outlet of the funnel head 320 located in the sealed space 700. The baffle 321 abuts against the surface of the template 220. Preferably, the baffle 321 is cubic in shape, and the size of the bottom of the baffle 321 matches the size of the pressing groove 210. In this embodiment, by setting the baffle 321, the powder flowing out of the funnel head 320 can be prevented from floating in the sealed space 700. At the same time, by abutting the baffle 321 against the surface of the template 220, the powder flowing out of the funnel head 320 can be prevented from flowing out in large quantities from the gap between the baffle 321 and the template 220 and remaining on the surface of the template 220.

[0039] In some alternative embodiments, such as Figure 8 As shown, the powder collection device used in the pressing equipment also includes a vibration device 800. The vibration device 800 includes a housing 810 and a turntable 820. The housing 810 has a receiving cavity 811 that can accommodate the rotation of the turntable 820. The housing 810 can be fixed by a fixing device to prevent the turntable 820 from deviating from its position when it rotates. The receiving cavity 811 is connected in series with a first flexible tube 520, that is, one end of the first flexible tube 520 is connected to one side of the receiving cavity 811, and the other end of the first flexible tube 520 is connected to the other side of the receiving cavity 811. In this way, the airflow carrying powder flowing in the first flexible tube 520 can enter the receiving cavity 811 from the first flexible tube 520 on one side. Under the impact of the airflow, the turntable 820 is driven to rotate. Then, the airflow flows into the first flexible tube 520 on the other side of the receiving cavity 811 as the turntable 820 rotates, and finally flows into the upper container 610. When specifically setting the installation position of the first hose 520, a portion of the first hose 520 is arranged around the edge of the receiving cavity 811, for example, the circumference of this portion of the first hose 520 is a semi-circle. Striking elements 821 are spaced apart along the circumferential edge of the turntable 820. The striking elements 821 are rotatably mounted on the turntable 820. The distance from the outermost edge of the striking element 821 to the rotation center of the turntable 820 is slightly smaller than the radius of the portion of the receiving cavity 811 not connected to the first hose 520, while the radius of the portion of the receiving cavity 811 surrounding the first hose 520 is smaller than the distance from the outermost edge of the striking element 821 to the rotation center of the turntable 820. The portion of the first hose 520 surrounding the edge of the receiving cavity 811 presses against the striking elements 821. To prevent severe wear or jamming of the turntable 821 when striking the receiving cavity 811, both the edge of the receiving cavity 811 and the striking elements 821 are made of soft materials, such as rubber. The portion of the first hose 520 disposed around the edge of the receiving cavity 811 is in contact with the second hose 310.

[0040] In this embodiment, the airflow entering the receiving cavity 811 drives the turntable 820 to rotate. When the striking element 821 on the turntable 820 rotates to the part where the first hose 520 is located around the edge of the receiving cavity 811, since the radius of this part is smaller than the distance from the outermost part of the striking element 821 to the rotation center of the turntable 820, and the striking element 821 will be squeezed and deformed, the outermost part of the striking element 821 will hit the side wall of this part. The deformation of the striking element 821 will buffer and prevent this part from being broken. Afterwards, the impact force is transmitted to make the second hose 310 vibrate, causing the powder adhering to the inner wall of the second hose 310 to be shaken off. Similarly, it can be understood that when the outermost part of the striking element 821 hits the side wall of this part, it will also cause the first hose 520 to vibrate, causing the powder adhering to the inner wall of the first hose 520 to be shaken off. Furthermore, since the striking element 821 can rotate relative to the turntable 820, when the striking element 821 rotates to this part, it will be blocked by the side wall of this part. At this time, the striking element 821 can abut against the side wall and rotate, so that the entire turntable 820 will not be stuck, ensuring its continuous rotation, so that the side wall of this part can be periodically impacted by the striking element 821.

[0041] In some alternative embodiments, such as Figure 8 As shown, rubber protrusions 521 are spaced apart on the outer wall of the first flexible tube 520, and the rubber protrusions 521 contact the outer wall surface of the second flexible tube 310. This allows the rubber protrusions 521 to act as a buffer when the striking element 821 periodically impacts the portion of the first flexible tube 520 surrounding the edge of the receiving cavity 811, preventing the second flexible tube 310 from vibrating too violently and causing unbalanced shaking, which would hinder the process of the powder entering the pressing groove 210 and affect the pressing of the magnetic powder core.

[0042] In some alternative embodiments, such as Figure 5As shown, the negative pressure storage device 600 also includes a support assembly 660, which includes a first support 661 and a second support 662. The second support 662 is slidably mounted on the first support 661, the lower container 620 is rotatably mounted on the first support 661, and the upper container 610 is fixed on the second support 662. A spring 663 is also provided between the first support 661 and the second support 662. A handle 664 is provided on the second support 662, and a roller 665 is provided at the bottom of the first support 661. When it is necessary to remove the stored windproof powder in the lower container 620, the upper container 610 is first lifted upward by the handle 664. The second support 662 slides upward relative to the first support 661. Due to the presence of the spring 663, the upper container 610 can be lifted without applying too much lifting force. After the upper container 610 has risen to a certain height, since the lower container 620 is rotatably mounted on the first support 661, only a force needs to be applied to tilt the lower container 620, and then the powder inside can be easily removed. In addition, when it is necessary to move the upper barrel 610 and the lower barrel 620 away at the same time or move them to the side of the press 100, a force can be applied to the lower barrel 620, the upper barrel 610, or the handle 664, so that the roller 665 can be rotated to drive the negative pressure storage device 600 to move as a whole.
