Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a tipping bucket feeding device for metal powder metallurgy. Background Technology

[0002] Metal powder metallurgy is a technology that uses metal powder as raw material to manufacture metal products through processes such as forming and sintering. Metal powder metallurgy is widely used in the fields of automobiles, aerospace, electronics, medical devices, and tool manufacturing. Common products include gears, bearings, cutting tools, and high-performance medical implants.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN219703503U) discloses a tipping bucket feeding device for metal powder metallurgy. The device includes a housing, a partition plate installed on the bottom surface inside the housing with its front and rear sides connected to the front and rear inner walls of the housing, respectively; a column rod movably installed on the upper part of the partition plate, with its front and rear ends hinged to the front and rear inner walls of the housing, respectively; a hopper connected to the column rod, with a tipping drive mechanism connected to the hopper; an installation chamber installed on the upper side wall of the housing; a cleaning mechanism located within the installation chamber; and a cylinder with its extended end connected to the cleaning mechanism. When cleaning the hopper is required, the hopper is kept in a tipped state, and the cleaning mechanism flushes the inner wall of the hopper. Since there are no working parts inside the hopper, only the inner wall surface needs to be rinsed, resulting in good cleaning performance and avoiding the problem of incomplete cleaning due to multiple dead corners.

[0004] Although the aforementioned patent has a good cleaning effect through the setting of the cleaning mechanism, which can avoid the problem of incomplete cleaning due to multiple dead corners, when feeding metal powder, the metal powder is easy to spill during the turning process, which wastes the metal powder. In addition, some metal powder will be adsorbed on the surface of the hopper during feeding, making it difficult to turn the metal powder more thoroughly and reduce the residue during feeding.

[0005] Therefore, this utility model provides a tipping bucket feeding device for metal powder metallurgy to solve the above problems. Utility Model Content

[0017] (III) Beneficial Effects

[0018] 1. With the scraping mechanism, when feeding metal powder, some powder will remain on the inner wall of the hopper. Over time, it will accumulate and stick to the hopper, making it difficult to clean. The scraping mechanism can scrape off the powder adsorbed on the inner wall of the hopper when the hopper is tipped to clean up the residual powder, making it easier to clean the hopper later. It can also reduce the residue during feeding and reduce the waste of metal powder.

[0019] 2. With the tilting mechanism, when the bucket is being fed, the tilting mechanism tilts the bucket upwards. When the bucket is at the top, the tilting mechanism helps the bucket tip over, preventing the bucket from getting stuck when it is halfway tipped over, which would cause metal powder to spill and result in waste. The tilting mechanism makes it easy to tip the bucket smoothly and steadily. Attached Figure Description

[0027] 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.

[0028] This utility model provides a tipping bucket feeding device for metal powder metallurgy, such as Figures 1-5 As shown, the tipping bucket feeding device for metal powder metallurgy includes a hopper 1, an inclined plate 2 fixedly connected to the bottom of the hopper 1, a scraping mechanism fixedly connected to the front of the inclined plate 2, a groove opened on the inner side wall of the hopper 1, an opening and closing mechanism slidably connected inside the groove, and a tilting mechanism fixedly connected to the back of the hopper 1.

[0029] The scraping mechanism includes a base plate 3, the outer surface of which is snapped onto the bottom of the hopper 1. An electric push rod 4 is fixedly connected to the bottom of the base plate 3. The outer surface of the electric push rod 4 is fixedly connected to the front of the inclined plate 2 via a support rod. Rotating sleeves 5 are fixedly connected to both ends of the base plate 3. A scraper 7 is rotatably connected to the inside of the rotating sleeve 5 via a rotating rod 6. Metal powder flows out from the hopper 1. After most of the metal powder has flowed out, the electric push rod 4 is activated. The electric push rod 4 drives the base plate 3 to extend and retract. The base plate 3 drives the scraper 7 to move on the inner wall of the hopper 1 via the rotating sleeve 5 and the rotating rod 6, scraping off the residue adsorbed on the inner wall of the hopper 1, reducing resource waste and facilitating subsequent cleaning.

[0030] The opening and closing mechanism includes a cover plate 8. Both sides of the cover plate 8 are slidably connected to the inside of the slide groove via sliders. A connecting rod 9 is fixedly connected to the upper surface of the cover plate 8. When the hopper 1 moves to the top, the electric push rod 10 is activated to drive the connecting rod 9 to extend and retract. The connecting rod 9 drives the cover plate 8 to extend and retract inside the hopper 1, so that the outlet of the hopper 1 can be blocked by the cover plate 8, so as to prevent metal powder from spilling out of the hopper 1 when the hopper is tipped, thus avoiding waste.

[0031] One end of the connecting rod 9 is fixedly connected to the electric push rod 10 (B), and the outer surface of the electric push rod 10 (B) is fixedly connected to one side of the hopper 1 by a fixing block.

[0032] The tilting mechanism includes a rotating component A 11, one end of which is fixedly connected to the back of the hopper 1, and the other end of which is fixedly connected to an electric push rod C 12. The bottom of the electric push rod C 12 is fixedly connected to a rotating component B 13. When tilting the hopper, the electric push rod C 12 is activated, which drives the rotating components A 11 and B 13 to rotate, making it easy to tilt the hopper 1 smoothly and avoiding jamming when the hopper 1 is tilted halfway, which would cause metal powder to spill and result in waste. The tilting mechanism makes it easy to tilt the hopper 1 smoothly and stably.

[0033] The tilting mechanism is set in two sets, one set is fixedly connected to the back of the hopper 1, and the other set is fixedly connected to the back of the inclined plate 2. The electric push rod 12 is set in two sets, one set going up and the other set going down, which makes it easy to tilt the hopper 1.

[0034] A sliding block 14 is fixedly connected to the bottom of the inclined plate 2. An arc plate 15 is slidably connected to the outer surface of the sliding block 14. When the hopper 1 is tipped, the inclined plate 2 slides within the arc plate 15 through the sliding block 14, which plays an auxiliary role and facilitates the smooth tipping of the hopper 1.

[0035] A sleeve rod 16 is fixedly connected to the top of the back of the hopper 1. Both ends of the sleeve rod 16 are rotatably connected to magnetic blocks 17. The hopper 1 is engaged in the external lifting module by the sleeve rod 16 and the magnetic blocks 17, and the hopper 1 is moved upward to facilitate material feeding.

[0036] Specifically, metal powder is placed in hopper 1, which is then secured to the external lifting module via sleeve rod 16 and magnetic block 17. Hopper 1 is moved upwards for easy material transfer. When hopper 1 reaches its highest point, electric push rod B 10 is activated, causing connecting rod 9 to extend or retract. Connecting rod 9 then causes cover plate 8 to extend or retract within hopper 1, effectively blocking the outlet of hopper 1 and preventing metal powder from spilling out during tipping, thus avoiding waste. Subsequently, during tipping, electric push rod C 12 is activated, causing rotating parts A and B to rotate. The push rods 12 are in two sets, one set pointing upwards and the other downwards, to facilitate the tipping of hopper 1. When tipping hopper 1, the inclined plate 2 slides within the arc-shaped plate 15 via the sliding block 14, which assists in the smooth tipping of hopper 1. After hopper 1 is tipped over, the cover plate 8 is opened, and the metal powder flows out from hopper 1. After most of the metal powder has flowed out, the A electric push rod 4 is activated. The A electric push rod 4 drives the bottom plate 3 to extend and retract. The bottom plate 3 drives the scraper 7 to move along the inner wall of hopper 1 through the rotating sleeve 5 and the rotating rod 6, scraping off the residue adsorbed on the inner wall of hopper 1, reducing resource waste and facilitating subsequent cleaning.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
