Description

Technical Field

[0001] This utility model belongs to the technical field of stamping devices, and in particular relates to a continuous stamping gear stamping device with waste material recycling. Background Technology

[0002] In the mass production of small- and medium-sized powder metallurgy gears, continuous stamping has become the mainstream production method in the industry because it can directly press metal powder into shape and reduce subsequent processing. Existing continuous powder metallurgy gear stamping equipment mainly consists of a frame, servo drive mechanism, punch assembly, master die, and feeding mechanism. During operation, the feeding mechanism continuously conveys premixed metal powder to the top of the master die, and the servo drive mechanism drives the punch to repeatedly press down, so that the powder is compacted in the cavity of the master die to form a gear blank, realizing continuous production.

[0003] However, after powder stamping, existing equipment leaves loose powder and scrap from the edges of the die cavity at the bottom. Since existing equipment lacks an automatic cleaning function, this scrap accumulates. When it accumulates to a certain extent, it encroaches on the effective space of the cavity, causing the clearance between the punch and the die to deviate from design requirements. This results in uneven density of the gear blanks, significant deviations in key dimensions, and surface depressions or impurities due to friction between the residual powder and the blank surface, leading to a significant decrease in product yield. Furthermore, to prevent blank cracking and die jamming caused by scrap accumulation, the machine must be stopped after stamping a certain number of parts, and the scrap in the die cavity must be manually cleaned with a soft brush or special scraper. Taking a typical daily production run as an example, this results in long downtime, reduced equipment efficiency, and a significant decrease in daily production capacity.

[0004] To address these issues, we provide a continuous stamping gear stamping device with waste recycling function. Utility Model Content

By cooperating with the waste recycling component, the stamping component and the rotating component, the problem that the existing gear stamping device does not have a waste recycling function is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0025] Please see Figure 1-5 This utility model relates to a continuous stamping gear stamping device with waste material recycling, comprising a frame 1, a waste material recycling component 2, a stamping component 3, and a rotating component 4.

The waste material recycling component 2 includes a sleeve fitted around the bottom of the female mold 31. The receiving cylinder 21 has a cleaning brush 22 fixedly connected to its inner cavity via a bearing. A gear 23 is fixedly connected to the bottom of the surface of the cleaning brush 22. A gear 24 meshes with the surface of the gear 23. A motor 25 is fixedly connected to the top of the gear 24. The motor 25 is fixedly connected to the receiving cylinder 21. A discharge pipe 26 is connected to the bottom of the cleaning brush 22 via a bearing. The rotating assembly 4 includes a hydraulic telescopic rod 41 fixedly connected to the ground. A motor 42 is fixedly connected to the top of the hydraulic telescopic rod 41. A connecting seat 43 is fixedly connected to the top of the motor 42. One side of the connecting seat 43 is fixedly connected to the receiving cylinder 21.

[0026] Specifically: the cleaning brush 22 has a hollow plastic body and wear-resistant nylon bristles. The bristles are evenly distributed in a ring array on the surface of the brush body, and the length of the bristles fits snugly against the inner wall of the female mold 31. The bottom of the cleaning brush 22 is connected to the discharge pipe 26 through a sealed bearing. The female mold 31 is made of metal and has a cavity on its top that matches the gear blank. The male mold 32 is a metal stamping head that matches the cavity of the female mold 31. The hydraulic telescopic rod 33 can drive the male mold 32 to rise and fall stably in the vertical direction. Example

[0027] Please see Figure 1-5 Based on Embodiment 1, the stamping assembly 3 further includes a sealing cylinder 34 fixedly connected to the other side of the connecting seat 43. Both the sealing cylinder 34 and the receiving cylinder 21 are fixedly connected to a fixing member 35. The fixing member 35 includes a gear ring 351 and a motor 352 fixedly connected to the surfaces of the sealing cylinder 34 and the receiving cylinder 21 via bearings. A gear 353 meshes with the surface of the gear ring 351. The bottom of the gear 353 is fixedly connected to the output shaft of the motor 352. A bevel gear 354 meshes with the top of the gear ring 351. A threaded tube 355 is fixedly connected to the inner cavity of the bevel gear 354. A lead screw 356 is threadedly connected to the inner cavity of the threaded tube 355. The other end of 56 extends into the inner cavity of the female mold 31. The fixing member 35 also includes mounting holes opened on the surfaces of the sealing cylinder 34 and the receiving cylinder 21. The threaded tube 355 is fixedly connected to the inner wall of the mounting hole through a bearing. Limiting holes are opened on the surfaces of the sealing cylinder 34 and the receiving cylinder 21 on both sides of the mounting hole. The inner cavity of the limiting hole is slidably connected to the limiting rod 357. The other end of the limiting rod 357 is fixedly connected to the lead screw 356. The surface of the female mold 31 is provided with a pin hole 358 for use with the lead screw 356. The cleaning brush 22 adopts a hollow design and has adsorption holes on its surface. The bottom of the receiving cylinder 21 is provided with a groove. The motor 25 is installed in the inner cavity of the groove.

[0028] Specifically: the sealing cylinder 34 seals the bottom of the female mold 31, providing stable bottom support and sealing for the stamping operation. Motor 352 drives gear 353 to rotate, which in turn rotates the gear ring 351, and then, through bevel gear 354, causes the threaded tube 355 to rotate. The threaded tube 355 drives the lead screw 356 to move, thus fixing the sealing cylinder 34 and the receiving cylinder 21 to the female mold 31. The mounting hole provides a stable bearing mounting position for the threaded tube 355, ensuring no offset during rotation. The limiting hole cooperates with the limiting rod 357. The screw 356 can be restricted from rotating with the threaded tube 355, ensuring that the screw 356 only extends and retracts axially. This prevents the rotation of the screw 356 from affecting the fixing effect on the female mold 31, improves the reliability and accuracy of the fixing operation, and reduces the fixing failure problem caused by the offset of the screw 356. The pin hole 358 is adapted to the screw 356, so that the screw 356 can be accurately inserted into the pin hole 358 when it extends and retracts. The hollow design of the cleaning brush 22, combined with the adsorption hole, provides a channel for the discharge of waste materials, preventing the accumulation of waste materials in the cleaning brush 22. The groove provides installation space for the motor 25.

[0029] The working principle of this utility model is as follows: Before the device operates, the frame 1 and the bottom of the rotating assembly 4 are fixed to the ground with bolts to ensure overall stability. During the stamping operation, the hydraulic telescopic rod 33 in the stamping assembly 3 drives the male mold 32 to move downwards and cooperate with the female mold 31 on the frame 1, compacting the metal powder in the cavity of the female mold 31 into a gear blank. During the waste recycling process, the motor 352 drives the gear 353 to rotate, the gear 353 drives the gear ring 351 to rotate, the gear ring 351 drives the bevel gear 354 to rotate, the bevel gear 354 drives the threaded tube 355 to rotate, the threaded tube 355 drives the lead screw 356 to move, and after the lead screw 356 disengages from the pin hole 358, the hydraulic telescopic rod 352 moves downwards. The retraction rod 41 retracts, causing the motor 42 and connecting seat 43 to descend, thereby separating the sealing cylinder 34 from the mother mold 31. Then, the hydraulic telescopic rod 41 extends out and fits against the bottom of the waste recycling component 2. Then, the reverse motor 352 fixes the receiving cylinder 21 to the mother mold 31. Then, the motor 25 starts, driving the gear 24 to rotate. The gear 24 drives the gear 23 to rotate, thereby causing the cleaning brush 22 to rotate in the inner cavity of the mother mold 31. The brush bristles clean the loose powder and corner waste remaining in the inner cavity of the mother mold 31. Under the action of the rotating cleaning brush 22, the waste enters the discharge pipe 26 through the suction hole and is finally discharged from the device, realizing automatic waste cleaning.
