Description

Technical Field

[0001] This utility model belongs to the field of powder metallurgy technology, specifically referring to a uniform feeding device for metal powder in powder metallurgy. Background Technology

[0002] In the powder metallurgy production process, workers need to frequently move and pour metal powder in the traditional manual feeding method. This is not only extremely labor-intensive and prone to fatigue from long-term operation, but also leads to low production efficiency. Moreover, manual operation makes it difficult to ensure the consistency and accuracy of each feeding.

[0003] To address the shortcomings of manual feeding, some production processes employ a method where metal powder is first fed into a hopper, and then the hopper is pushed to deliver the powder into the mold. However, this method still has significant drawbacks: firstly, it increases feeding time; secondly, during the movement of the hopper, the powder inside is prone to accumulation and uneven distribution due to inertia, friction, and other factors, affecting the quality of subsequent molded products. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a uniform feeding device for metal powder in powder metallurgy, which effectively solves the problems of long feeding time by manual labor and material box, and the easy accumulation and uneven distribution of powder, which affect product quality.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: A uniform feeding device for metal powder in powder metallurgy includes a base, a mold is provided on the base, an mounting frame is fixed on one side of the base, a hopper is installed on the mounting frame, a stirring device is provided in the hopper, a conveying pump connected to the bottom of the hopper is installed on one side of the bottom of the hopper, one end of the conveying pump is connected to a telescopic discharge pipe, which conveys the metal powder in the hopper to the mold through the telescopic discharge pipe, and a pushing structure is provided at the connection between the mold and the base to uniformly disperse the metal powder pumped into the mold.

[0006] Preferably, the pushing structure includes a lifting cylinder, which is fixed inside the base and extends to the top surface of the base. An L-shaped support frame is fixed to the top of the lifting cylinder. A hollow outer plate is fixed to the outer side of the mold. The top of the support frame extends vertically through the outer plate. A support column is horizontally fixed inside the outer plate. A spring is fitted around the support column and fixed between the outer plate and the support frame. A rotary motor is installed outside the support frame. A cam is fixed to the output end of the rotary motor. An abutment plate is also fixed to the outer plate, and the cam abuts against one side of the abutment plate.

[0007] Preferably, the mold includes a bottom mold and an outer mold. The bottom mold is slidably disposed on the top surface of the base, and the outer mold is sleeved outside the bottom mold and fits tightly. The outer connecting plate is fixed on the outer side surface of the outer mold.

[0008] Preferably, the bottom of the bottom mold is provided with a horizontal sliding groove, and a slider that cooperates with and slides relative to the sliding groove is fixed on the top surface of the base. The longitudinal section of the sliding groove and the slider is T-shaped or L-shaped.

[0009] Preferably, the length of the slider is less than the length of the groove and it is located near one end of the groove.

[0010] Preferably, the telescopic discharge pipe is a corrugated pipe, and a fixed connecting plate is fixed to one end of the telescopic discharge pipe. A telescopic cylinder is fixedly connected to the fixed connecting plate, and the movable end of the telescopic cylinder is fixedly connected to the fixed connecting plate.

[0011] The beneficial effects achieved by adopting the above-described structure are as follows:

[0012] 1. By pumping powder and using a mold-driven structure, the feeding and powder distribution can be completed quickly. Compared with traditional manual or hopper feeding, the feeding time of a single product is greatly shortened, the overall production efficiency is significantly improved, and the needs of large-scale production are met.

[0013] 2. The pushing structure ensures that the metal powder pumped into the mold is evenly dispersed, effectively avoiding powder accumulation and agglomeration, ensuring that the density of each part of the molded product is consistent, and improving product quality stability and yield.

[0021] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-5 As shown, this utility model proposes a uniform feeding device for metal powder in powder metallurgy, including a base 1, a mold 2 on the base 1, a mounting frame 3 fixed on one side of the base 1, a hopper 4 on the mounting frame 3, a stirring device 5 inside the hopper 4, a conveying pump 6 connected to the bottom of the hopper 4 on one side of the bottom of the hopper 4, a telescopic discharge pipe 7 connected to one end of the conveying pump 6, the telescopic discharge pipe 7 being a corrugated pipe, a fixed connecting plate 21 fixed to one end of the telescopic discharge pipe 7, a telescopic cylinder 22 fixedly connected to the fixed connecting plate 21, the movable end of the telescopic cylinder 22 being fixedly connected to the fixed connecting plate 21, the telescopic cylinder 22 being used to adjust the length of the telescopic discharge pipe 7, so that the metal powder in the hopper 4 is sent to the mold 2 through the telescopic discharge pipe 7, and a pushing structure 8 is provided at the connection between the mold 2 and the base 1, so that the metal powder pumped into the mold 2 is evenly dispersed, effectively avoiding powder accumulation.

[0023] like Figure 3As shown, the pushing structure 8 includes a lifting cylinder 13, which is fixed inside the base 1 and extends to the top surface of the base 1. An L-shaped support frame 14 is fixed to the top of the lifting cylinder 13. A hollow outer plate 15 is fixed to the outer side of the mold 2. The top of the support frame 14 extends vertically through the outer plate 15. A support column 16 is horizontally fixed inside the outer plate 15. A spring 17 is fixed between the outer plate 15 and the support frame 14 and the support column 16. A rotary motor 18 is installed outside the support frame 14. A cam 19 is fixed to the output end of the rotary motor 18. An abutment plate 20 is also fixed on the outer plate 15. The cam 19 abuts against one side of the abutment plate 20. The motor drives the cam 19 to rotate. The cam 19 presses against the abutment plate 20, which drives the outer plate 15 and the outer mold 10 to move. The outer mold 10 drives the bottom mold 9 to move. Under the action of the spring 17's own restoring force, the mold 2 moves back and forth, dispersing the metal powder evenly inside the mold 2.

[0024] like Figure 2 , 3 As shown in Figure 5, the mold 2 includes a bottom mold 9 and an outer mold 10. The bottom mold 9 is slidably disposed on the top surface of the base 1, and the outer mold 10 is fitted over the bottom mold 9 and fits tightly. An outer plate 15 is fixed on the outer side of the outer mold 10. The bottom of the bottom mold 9 is provided with a horizontal groove 11. A slider 12 that cooperates with and slides relative to the groove 11 is fixed on the top surface of the base 1. The longitudinal section of the groove 11 and the slider 12 is T-shaped or L-shaped, which limits the vertical movement of the bottom mold 9. The length of the slider 12 is less than the length of the groove 11 and is located near one end of the groove 11, ensuring that the bottom mold 9 will not detach from the slider 12 during the sliding process, making it easy to remove the bottom mold 9 for replacement.

[0025] In practical use, metal powder is poured into hopper 4, the control system is turned on, and the feeding amount, mold 2 pushing parameters, etc. are set. Telescopic cylinder 22 drives fixed connecting plate 21 and one end of telescopic discharge pipe 7 to move. One end of telescopic discharge pipe 7 is moved above mold 2. Conveying pump 6 is started. Under the action of the pump, the metal powder in hopper 4 is transported to mold 2 and bottom mold 9 along telescopic discharge pipe 7. At the same time, the control system starts pushing structure 8 according to preset parameters. The motor drives cam 19 to rotate. Cam 19 presses against plate 20, driving outer plate 15 and outer mold 10 to move. Outer mold 10 drives bottom mold 9 to move. Under the action of spring 17's own restoring force, mold 2 moves back and forth, so that the powder falling into mold 2 is gradually distributed evenly during the movement. After pushing structure 8 stops running, it can enter the subsequent pressing process. After pressing is completed, lifting cylinder 13 drives support frame 14 and outer mold 10 to rise as a whole, and the formed metal part is removed and enters the subsequent sintering and other powder metallurgy forming processes. The above steps are repeated to carry out the next round of feeding operation.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
