Description

Technical Field

[0001] The invention relates to the field of powder metallurgy mixing, and in particular to a processing mechanism for powder metallurgy. Background Art

[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder (or a mixture of metal powder and non-metallic powder) as metal powder, and then forms and sinters it to manufacture metal materials, composite materials and various types of products.

[0003] An industrial powder metallurgy kneading machine with publication number CN117398871A in the prior art, through the arrangement of the cooperation between the kneading mechanism and the crimping mechanism, can improve the compactness between the raw materials and extrude the raw materials in the process of stirring and kneading the raw materials with the cooperation of the crimping mechanism, thereby cooperating with the kneading mechanism to improve the uniformity of the raw material mixing and the kneading efficiency.

[0004] Although it can improve the uniformity of mixing powder metallurgy raw materials, in the actual processing process, since the powder metallurgy raw materials are mixed when poured into the mixing box, a certain amount of raw materials are generally poured into the mixing box in batches. This will cause the raw materials to be stratified in the mixing box, and the position of the feed port is fixed, so the raw materials will accumulate in one place in the mixing box. Therefore, it takes a long time to stir the raw materials in the subsequent process to mix them evenly, which greatly reduces the production efficiency of the device. Otherwise, it will affect the subsequent powder metallurgy production quality. However, the mixing time of the powder particles cannot be too long, otherwise it will cause problems such as changes in the distribution of the powder particles and work hardening on the particle surface.

[0005] Therefore, a processing mechanism for powder metallurgy is provided to solve the above-mentioned problems. Summary of the invention

DETAILED DESCRIPTION

[0028] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0029] like Figure 1-Figure 8 A processing mechanism for powder metallurgy shown in the figure comprises a mixing tank 1, and a fixed rod 2 rotatably connected to the inner side of the mixing tank 1, a plurality of stirring rods 22 are fixedly connected to the outer wall of the fixed rod 2, a discharge pipe 24 is fixedly connected to the bottom of the mixing tank 1, a fixed cover 3 is arranged on the top of the mixing tank 1, and the bottom end of the fixed cover 3 is inserted into a part of the top of the inner side of the mixing tank 1, a rotating rod 4 is fixedly connected to the top of the fixed rod 2 and rotatably connected to the inner top of the fixed cover 3, a plurality of discharge tanks 5 are arranged on the outer side of the fixed cover 3, and a connecting frame 40 is fixedly connected between the bottom of the plurality of discharge tanks 5 and the mixing tank 1 A fan-shaped discharge port 6 is provided at the bottom of the discharge tank 5, and an adjustment mechanism for controlling the discharge amount is provided at the discharge port 6. A through hole 17 is provided on the outer wall of the fixed cover 3 and at a position corresponding to the discharge port 6. A guide frame 7 is obliquely fixedly connected between the discharge port 6 and the through hole 17. An upper fan-shaped plate 8, a middle fan-shaped plate 11 and a lower fan-shaped plate 13 are obliquely arranged on the inner side of the fixed cover 3, and the upper fan-shaped plate 8, the middle fan-shaped plate 11 and the lower fan-shaped plate 13 are staggered on the inner side of the fixed cover 3. The rotating rods 4 are all penetrated and fixedly connected to the top inner sides of the upper fan-shaped plate 8, the middle fan-shaped plate 11 and the lower fan-shaped plate 13;

[0030] A material distribution cover 10 is fixedly connected to the outer wall of the rotating rod 4 and is located between the lower fan-shaped plate 13 and the stirring rod 22. A material distribution port 38 is opened at the eccentric position of the bottom of the material distribution cover 10. A fixing ring 12 is fixedly connected to the top of the material distribution cover 10 and is located between the mixing tank 1 and the fixed cover 3. The fixing ring 12 is rotatably connected to the outside of the fixed cover 3 and the inside of the mixing tank 1 respectively. A servo motor 39 is fixedly connected to the top of the fixed cover 3. The output end of the servo motor 39 passes through the fixed cover 3 and is fixedly connected to the top of the rotating rod 4.

[0031] When mixing raw materials during powder metallurgy processing, first, the raw materials of the matching ratio are put into the discharge tank 5 respectively. When discharging, the sealing plate 25 can be adjusted to close the discharge port 6. When the material port is added, the sealing plate 25 can be opened and the servo motor 39 can be controlled to start. Then the raw materials in the discharge tank 5 are discharged from the through hole 17 through the guide frame 7, and then the servo motor 39 will drive the rotating rod 4 and the fixed rod 2 to rotate at the same time, and then the upper fan-shaped plate 8, the middle fan-shaped plate 11 and the lower fan-shaped plate 13 are driven by the rotating rod 4 to rotate under the multiple through holes 17, and then the raw materials falling from the through holes 17 are successively caught. At the same time, the raw materials falling on the upper fan-shaped plate 8 will slide to the middle fan-shaped plate 11 below by its own gravity, mix with the raw materials on the middle fan-shaped plate 11 and fall, and then slide to the lower fan-shaped plate 13, mix with the raw materials on the lower fan-shaped plate 13 and fall into the material distribution cover 10;

[0032] Then, the rotating rod 4 drives the distribution cover 10 and the distribution port 38 to rotate. Since the distribution port 38 is set at the eccentric position below the distribution cover 10, the raw materials that have been mixed multiple times can be evenly discharged to every place in the mixing tank 1, thereby realizing the pretreatment of the mixed raw materials and avoiding the problem of the raw materials being layered and piled up in one place, which leads to the subsequent long mixing time. After the discharge is completed, the servo motor 39 can continue to drive the rotation of the fixed rod 2 and the stirring rod 22 to achieve uniform mixing of the raw materials in the mixing tank 1. Finally, after the mixing is completed, the discharge pipe 24 is opened to discharge the raw materials.

[0033] In order to avoid the blockage of raw materials in the discharge tank 5 and affect the normal operation of the device, the inner side of the discharge tank 5 is rotatably connected to the limit rod 14, and the outer wall of the limit rod 14 is fixedly connected to the auger piece 15. A connecting mechanism for transmission is provided between the limit rod 14 and the fixed ring 12, and the connecting mechanism includes a gear ring 16. The bottom of the limit rod 14 is fixedly connected to a connecting rod 23 and runs through the bottom of the discharge tank 5. The bottom of the connecting rod 23 is fixedly connected to a gear 18. The gear ring 16 is fixedly connected to the outer wall of the fixed ring 12, and the gear 18 and the gear ring 16 are meshed with each other;

[0034] When the raw materials in the discharge tank 5 enter the mixing tank 1 for mixing, the rotation of the rotating rod 4 and the fixed rod 2 is driven by the servo motor 39, which will drive the material distribution cover 10 and the fixed ring 12 to rotate, and at the same time drive the gear ring 16 to rotate, thereby driving the multiple meshing gears 18 to rotate at the same time, and then drive the limit rod 14 and the auger piece 15 to rotate at the same time through the connecting rod 23, thereby realizing the material guiding processing of the raw materials in the discharge tank 5, avoiding blockage caused by material agglomeration and affecting the normal operation of the device.

[0035] In order to improve the stability of the rectangular plate 20, the upper fan-shaped plate 8, and the middle fan-shaped plate 11 during rotation, circular grooves 9 are provided on the inner side of the fixed cover 3 and at positions corresponding to the upper fan-shaped plate 8, the middle fan-shaped plate 11, and the lower fan-shaped plate 13. The outer walls of the upper fan-shaped plate 8, the middle fan-shaped plate 11, and the lower fan-shaped plate 13 are fixedly connected with arc plates 19 and slidably connected to the inner side of the circular grooves 9. Through the arrangement of the arc plates 19 and the circular grooves 9, the outer sides of the rectangular plate 20, the upper fan-shaped plate 8, and the middle fan-shaped plate 11 can be supported and guided when the raw materials are pre-mixed, so as to avoid excessive falling of raw materials on the rectangular plate 20, the upper fan-shaped plate 8, and the middle fan-shaped plate 11, which may cause unstable operation of the device due to gravity.

[0036] In order to further improve the pre-mixing effect of the device, the upper fan-shaped plate 8, the middle fan-shaped plate 11 and the lower fan-shaped plate 13 are fixedly connected to the end portions on one side thereof. Through the arrangement of the rectangular plate 20, the raw materials falling on the rectangular plate 20, the upper fan-shaped plate 8 and the middle fan-shaped plate 11 can be better dropped onto the plate below and mixed with the raw materials below. Moreover, the top sides of the rectangular plate 20, the upper fan-shaped plate 8, the middle fan-shaped plate 11 and the lower fan-shaped plate 13 are fixedly connected with baffles 21. Through the arrangement of the baffles 21, the raw materials falling on the rectangular plate 20, the upper fan-shaped plate 8 and the middle fan-shaped plate 11 can be shielded to avoid directly sliding into the mixing tank 1 and affecting the pre-mixing effect.

[0037] In order to control and adjust the amount poured into the mixing tank 1 according to the ratio of the powder metallurgy raw materials, the regulating mechanism includes a blocking plate 25, an adjusting chamber 26 is provided at the bottom end of the discharge tank 5, the end of the blocking plate 25 is rotatably connected to the middle part of the inner side of the adjusting chamber 26 and blocks the discharge port 6, an arc groove 27 is provided at the top of the discharge tank 5 and is connected to the adjusting chamber 26, a rotating rod 28 is movably connected to the inner side of the arc groove 27, a threaded rod 29 is fixedly connected to the bottom of the rotating rod 28, a threaded groove 31 is provided at the top of the blocking plate 25, the bottom of the threaded rod 29 is threadedly connected to the inner side of the threaded groove 31, and the top of the rotating rod 28 is connected to the inner side of the threaded groove 31.

A chute 32 is provided on the side wall of the discharge tank 5 and is connected to the arc groove 27. A pointer 33 is slidably connected to the inner side of the chute 32. The movement of the pointer 33 is facilitated by the chute 32 during adjustment. The side wall of the pointer 33 is rotatably connected to the outer wall of the rotating rod 28 to prevent the pointer 33 from rotating when the rotating rod 28 rotates, which affects the normal operation of the device. An indicator plate 34 is fixedly connected to the outer wall of the discharge tank 5 and is located below the chute 32. A displacement scale 35 is provided on the top of the indicator plate 34 and at a position corresponding to the pointer 33.

[0038] When the raw materials poured into the mixing tank 1 are controlled and adjusted, the polygonal block 30 is first twisted with a wrench to drive the rotating rod 28 and the threaded rod 29 to rotate, and a part of the threaded groove 31 is screwed out, so that the polygonal block 30 can release the squeezing of the upper surface of the discharge tank 5, and the position restriction of the blocking plate 25 can be released. Then, the polygonal block 30 is pushed to drive the rotating rod 28 to slide in the arc groove 27, and at the same time, the blocking plate 25 is driven to rotate inside the adjustment cavity 26, so as to adjust the size of the discharge port 6, so as to realize the amount of raw materials discharged from the discharge tank 5. At the same time, the movement of the rotating rod 28 will drive the pointer 33 to move on the indicator plate 34, and then observe the position of the pointer 33 on the displacement scale 35, and the blocking position of the discharge port 6 can be accurately adjusted according to the ratio of the raw materials. After the adjustment is completed, the polygonal block 30 can be tightened in the reverse direction with a wrench to drive the rotating rod 28 and the threaded rod 29 to rotate in the reverse direction, so that the threaded rod 29 is screwed into the inner side of the thread groove 31, and then the bottom of the polygonal block 30 will squeeze the upper surface of the discharge tank 5 to fix the position of the blocking plate 25.
