Description

Technical Field

[0001] The utility model relates to the technical field of gear metallurgy processing, in particular to a gear metallurgy processing quantitative feeding device. Background Art

[0002] In the powder metallurgy double gear processing mold, the general mold design is to design a stepped countersunk hole in the middle mold. The double gear parts are completely surrounded by the upper punch, the middle mold and the lower punch during shaping, forming a relatively closed space between the three. The upper punch and the lower punch apply pressure to the parts at the same time to force the parts to undergo plastic deformation for processing.

[0003] At present, the existing gear metallurgical processing (such as patent number: CN213469572U) discloses an automatic feeding device for powder metallurgical gear processing, which is provided with a conveying device and a feeding box. The conveying device can drive the feeding box to perform translational movement, thereby changing the position of the feeding box relative to the entire box body, so that the feeding box can move to the bottom of the discharge port by itself to complete the loading work, and then provide power for it through a hydraulic cylinder and a telescopic rod to transport the metal powder required for metallurgical gear processing to the loading position, thereby realizing automatic loading.

[0004] However, in the process of implementing the above technical solution, it was found that there were at least the following technical problems: automatically adding materials to the interior of the mold through a conveyor belt, opening the intercepting plate at the bottom to allow the materials to enter the interior of the mold, and manually controlling the closing of the intercepting plate, resulting in different closing speeds and different amounts of material put in each time, which affects the processing of the gears.

[0007] (II) Technical solution

The overall idea is as follows:

[0022] In view of the problems existing in the prior art, the utility model provides a quantitative feeding device for gear metallurgical processing, comprising a mold body 1 and a gear body 11, wherein both side ends of the mold body 1 are fixedly installed with a first telescopic rod 12, a material storage box 14 is arranged at the top of the mold body 1, a second closing sleeve 24 is fixedly installed inside the material storage box 14, a first closing sleeve 23 is rotatably installed at the top of the second closing sleeve 24, a transmission rod 22 is fixedly installed at the top of the first closing sleeve 23, a gear ring 21 is fixedly installed at the top of the transmission rod 22, and the first closing sleeve 23 and the gear ring 21 are fixedly installed at the top of the transmission rod 22. The second closing sleeve 24 is symmetrically designed. The interior of the second closing sleeve 24 is hollow, and there are two downward grooves at the top of the second closing sleeve 24. The gear ring 21 and the transmission rod 22 are rigidly connected. The gear ring 21 and the transmission rod 22 rotate synchronously. The gear ring 21 drives the transmission rod 22 to rotate forward, allowing the first closing sleeve 23 to slide inside the second closing sleeve 24. At the same time, the first closing sleeve 23 rotates inside the sealing groove 25. The first closing sleeve 23 and the second closing sleeve 24 rotate alternately to open one side of the second closing sleeve 24.

[0023] A sealing groove 25 is provided at the top of the second closed sleeve 24, and two fixed plates 15 are fixedly installed at the top of the storage box 14. A rack 19 is slidably installed inside each fixed plate 15, and a second telescopic rod 18 is fixedly installed on both side ends of each rack 19. The end of the second telescopic rod 18 is fixedly connected to the fixed plate 15 for telescoping. A diverter ring 16 is fixedly installed at the bottom end of the storage box 14, and a feeding port 17 is provided at the bottom end of the diverter ring 16. The material enters the interior of the diverter ring 16 through the second closed sleeve 24. At the same time, a feeding port 17 is provided at the bottom end of the diverter ring 16. The feeding port 17 is annular in design. The material enters the top of the mold body 1 along the feeding port 17, and the distribution area of ​​the material is increased through the feeding port 17. Support plates 13 are fixedly installed on both side ends of the storage box 14, and the end of the support plate 13 is fixedly connected to the first telescopic rod 12.

[0024] Working principle:

[0025] The first step is to add raw materials into the storage box 14 during use, and then drive the first telescopic rod 12 to extend and retract the first telescopic rod 12. The top of the first telescopic rod 12 drives the support plate 13 to move, so that the storage box 14 moves to the top of the mold body 1, and drives multiple second telescopic rods 18 to extend and retract the second telescopic rods 18 on the inner side of the fixed plate 15. At the same time, the top of the second telescopic rod 18 drives the rack 19 to slide on the side end of the fixed plate 15. At the same time, one side of the rack 19 is equipped with multiple latch teeth, which fit with the surface of the gear ring 21. At the same time, the rack 19 on the other side moves in the opposite direction, driving the gear ring 21 to rotate. The gear ring 21 It is rigidly connected to the transmission rod 22, and the gear ring 21 rotates synchronously with the transmission rod 22. The gear ring 21 drives the transmission rod 22 to rotate in the positive direction, allowing the first closing sleeve 23 to slide inside the second closing sleeve 24. At the same time, the first closing sleeve 23 rotates inside the sealing groove 25. The first closing sleeve 23 and the second closing sleeve 24 rotate alternately, and one side of the second closing sleeve 24 is opened. The material enters the inside of the diverter ring 16 through the second closing sleeve 24. At the same time, a feeding port 17 is opened at the bottom end of the diverter ring 16. The feeding port 17 is annular in design. The material enters the top of the mold body 1 along the feeding port 17, and the distribution area of ​​the material is increased through the feeding port 17.

[0026] In the second step, the material enters the top of the mold body 1 through the feeding port 17, and the powder is thermoplastically molded by heating metallurgy to form the gear body 11. The first telescopic rod 12 is driven to move to one side, and the support plate 13 is pushed to move. The support plate 13 drives the storage box 14 to leave the top of the mold body 1, so as to facilitate the material collection of the gear body 11. At the same time, the rack 19 is pushed to slide on one side of the fixed plate 15 by driving the second telescopic rod 18, and the gear ring 21 and the transmission rod 22 are driven to rotate, so that the first closing sleeve 23 rotates at a uniform speed inside the sealing groove 25. When the first closing sleeve 23 and the second closing sleeve 24 are interlaced with each other, the first closing sleeve 23 and the second closing sleeve 24 are in a semi-closed state, and the material will also enter the inside of the diverter ring 16 along the second closing sleeve 24. By controlling the interlacing range of the first closing sleeve 23 and the second closing sleeve 24, the feeding speed and feeding amount of the material are adjusted.
