Description

Technical Field

[0001] This invention relates to the field of tungsten rod production, specifically to a drying and compaction device for tungsten rod production. Background Technology

[0002] Tungsten rods are rod-shaped materials made primarily of metallic tungsten. They have low thermal expansion and good thermal conductivity, sufficient electrical resistance, and high elastic modulus. Due to their extremely high melting point, density, and hardness, they have important applications in industry, military, scientific research, and other fields.

[0003] Tungsten rods require drying and compaction during preparation, primarily to increase the density of the billet, improve material properties, and ensure the stability of subsequent sintering processes. Furthermore, the reduced friction between dried tungsten powder particles makes them easier to compact during vibration, improving compaction efficiency. Workers first load the dried tungsten powder into rubber sleeves, then compact it using a vibrator. Currently, existing drying and compaction devices use a screw-equipped conveyor pipe to transport the tungsten powder, and a rotating table to reposition multiple rubber sleeves for continuous feeding. However, when the rotating table repositions the rubber sleeves, if the screw continuously transports the tungsten powder, it can easily fall into the gaps between the rubber sleeves, increasing the difficulty of feeding the tungsten powder.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-8The diagram shows a drying and compacting device for tungsten rod production, comprising a base 1 and a feeding cylinder 2 fixedly installed on top of the base 1. Multiple rubber sleeves 3 are arranged symmetrically on the inner side of the feeding cylinder 2. A storage tank 4 is installed above the base 1 to store tungsten powder. A heater 5 is installed on the outer side of the storage tank 4 to heat and dry the tungsten powder inside. The storage tank 4 is connected to the base 1 via multiple legs. A discharge pipe 6 is fixedly installed at the bottom of the storage tank 4 to discharge the dried tungsten powder downwards. A vibration platform 7 is fixedly installed on top of the base 1. The rubber sleeves 3 containing tungsten powder can be placed on top of the vibration platform 7, and the tungsten powder inside the rubber sleeves 3 is compacted by the vibration platform 7. The device also includes a receiving mechanism that allows the multiple rubber sleeves 3 to receive material sequentially. The receiving mechanism is installed on top of the feeding cylinder 2.

[0022] The receiving mechanism includes a top plate 8 rotatably mounted on the top of the material receiving cylinder 2. The surface of the top plate 8 has multiple centrally symmetrically distributed first receiving holes, the number of which is the same as the number of rubber sleeves 3. The top of the discharge pipe 6 contacts the top of the top plate 8, and the top of the rubber sleeve 3 contacts the bottom of the top plate 8. A material receiving tray 9 is provided inside the material receiving cylinder 2, and the bottom of the rubber sleeve 3 contacts the top of the material receiving tray 9. Multiple centrally symmetrically distributed U-shaped frames 10 are fixedly installed at the bottom of the top plate 8, the number of which is the same as the number of rubber sleeves 3. The outer sides of the rubber sleeves 3 are... The inner side of the U-shaped frame 10 contacts each other, allowing the top plate 8 to cooperate with the feeding tray 9 to store multiple rubber sleeves 3. When the top plate 8 rotates, the U-shaped frame 10 drives the rubber sleeves 3 to move in a circular motion around the top plate 8. When the rubber sleeves 3 are aligned with the discharge pipe 6, the tungsten powder in the storage tank 4 can enter the rubber sleeves 3 through the first receiving hole, realizing continuous feeding of tungsten powder. A toothed ring 11 is fixedly installed on the outer side of the top plate 8, and an annular support 12 is fixedly installed on the top of the feeding cylinder 2. A drive motor 13 is fixedly installed on the bottom of the annular support 12, and the output end of the drive motor 13 is fixedly installed with the toothed ring. The drive gear 14, which is matched with the drive motor 13, can drive the drive gear 14 to rotate intermittently. The outer side of the feeding cylinder 2 is provided with a feeding opening and a discharging opening. An empty rubber sleeve 3 can be inserted through the feeding opening, and a rubber sleeve 3 containing tungsten powder can be removed through the discharging opening. A first baffle 32 and a second baffle 33 are fixedly installed on the top of the top plate 8. The second baffle 33 is located inside the first baffle 32. The inner side of the first baffle 32 and the outer side of the second baffle 33 are in contact with the outer side of the discharge pipe 6, so that when the top plate 8 rotates, it can drive the first baffle 32 and the second baffle 33 along the discharge pipe. The outer side of tube 6 rotates to shield the leaking fine tungsten powder. A sealing disc 34 is rotatably installed on the inner side of the top plate 8. The surface of the sealing disc 34 has multiple second vent holes corresponding to the first vent hole. A pull block 35 is fixedly installed on the outer side of the sealing disc 34. Both the material cylinder 2 and the outer side of the top plate 8 have long grooves for the pull block 35 to slide and limit its movement. Pulling the pull block 35 can make the sealing disc 34 rotate along the inner side of the top plate 8, so that the second vent holes on the sealing disc 34 are misaligned with the first vent holes on the top plate 8, thereby sealing the top plate 8 and cleaning the fine tungsten powder remaining on the top plate 8.

[0023] Example 2: Please refer to Figures 3-8This embodiment further illustrates Example 1. The material-setting mechanism shown in the figure includes multiple support rods 17 centrally symmetrically fixedly installed on the top plate 8. Two symmetrically distributed clamping plates 18 are provided on the outer side of the rubber sleeve 3. A rotating rod 19 is fixedly installed at one end of the clamping plate 18, extending to the bottom of the material tray 9, allowing the clamping plate 18 to swing around the rotating rod 19 as a fulcrum. Anti-slip texture is provided on the side of the clamping plate 18 near the rubber sleeve 3. A sleeve plate 20 is fixedly installed on the inner side of the material tray 9, and the support rods 17 slide through the sleeve plate 20. When the top plate 8 rotates, the sleeve plate 20 can be rotated through the support rods 17, thereby realizing the rotation of the material tray 9. A frame-shaped slide 21 is provided between the two rotating rods 19, and the frame-shaped slide 21 is fixedly installed on the bottom of the material tray 9. The bottom end of the rotating rod 19 is fixedly installed with a driven gear 22. A rack 23 that cooperates with the driven gear 22 is slidably installed on the outer side of the frame-shaped slide 21, so that when the rack 23 moves, it can drive the driven gear 22 to rotate, thereby realizing the swing of the clamping plate 18. The two adjacent racks 23 are symmetrically distributed, so that the two adjacent clamping plates 18 can clamp the outer side of the rubber sleeve 3, thereby positioning the rubber sleeve 3. A moving plate 24 is fixedly installed between the two racks 23. A first spring 25 is fixedly installed between the moving plate 24 and the frame-shaped slide 21. A guide rod 26 is fixedly installed at the bottom of the moving plate 24. A second frame 27 is fixedly installed at the bottom of the material tray 9. A fixed plate 28 is provided on the inner side of the second frame 27. The top of the fixed plate 28 is... The guide rod 26 is provided with a first arc-shaped groove and a second arc-shaped groove for limiting and sliding. The radius of the first arc-shaped groove is smaller than that of the second arc-shaped groove. The first arc-shaped groove is connected to the second arc-shaped groove through two inclined grooves. The two ends of the second arc-shaped groove are aligned with the material inlet and outlet of the material cylinder 2, respectively. When the guide rod 26 moves from the second arc-shaped groove to the inclined groove, it can drive the moving plate 24 on the guide rod 26 to move along the outside of the frame-shaped slide 21, thereby realizing the movement of the rack 23. A first frame 15 is fixedly installed at the bottom of the material cylinder 2. A positioning plate 16 is rotatably installed on the inner side of the first frame 15. The bottom end of the support rod 17 is fixedly connected to the top of the positioning plate 16, so that when the top plate 8 rotates, the positioning plate 16 can be driven to rotate synchronously through the support rod 17. To improve the stability of the circular motion of the support rod 17, multiple abutment rods 36 are slidably installed on the inner side of the positioning plate 16 in a centrally symmetrical manner. The number of abutment rods 36 is the same as the number of U-shaped frames 10. A second spring 37 is fixedly installed between one end of the abutment rod 36 and the inner side of the positioning plate 16. The end of the abutment rod 36 away from the second spring 37 is a hemispherical structure. A one-third spherical groove is opened on the inner side of the first frame 15 for the abutment rod 36 to be inserted into the groove for positioning. When the top plate 8 rotates, the abutment rod 36 on the positioning plate 16 can disengage from the spherical groove on the inner side of the first frame 15 and compress the second spring 37. When the top plate 8 stops rotating, the rebound force of the second spring 37 can be used to insert the abutment rod 36 into the corresponding spherical groove to provide positioning for the top plate 8.

[0024] Example 3: Please refer to Figure 3 and Figure 4 This embodiment further illustrates other embodiments. The adjusting mechanism shown in the figure includes a screw 29 rotatably mounted on the bottom of the top plate 8. A handle 30 is fixedly mounted on the top of the screw 29. The sleeve 20 is threadedly assembled with the screw 29 via an internal thread. When the handle 30 is rotated, the sleeve 20 can be moved along the outside of the support rod 17 via the screw 29, thereby adjusting the height of the material tray 9. This facilitates the storage of rubber sleeves 3 of more sizes. Furthermore, a scale strip is provided on the inner side of the material tray opening of the material tray 2. The fixed plate 28 is rotatably mounted on the inner side of the second frame 27. Multiple centered... Symmetrically distributed support arms 31 have protrusions at the ends of the support arms 31 away from the fixed plate 28. The inner side of the material cylinder 2 has a limiting groove for the protrusions to slide. When the material cylinder 9 pulls the fixed plate 28 upward through the second frame 27, the fixed plate 28 can drive the protrusions on the support arms 31 to move along the limiting groove, providing a limit for the fixed plate 28 and preventing the fixed plate 28 from rotating. Multiple centrally symmetrically distributed sliding balls 38 are fixedly installed on the inner side of the second frame 27. The top of the fixed plate 28 has an annular sliding groove for the sliding balls 38 to slide, which facilitates the smooth rotation of the second frame 27 along the outer side of the fixed plate 28.

[0025] Working principle: First, the operator starts the heater 5 to heat and dry the tungsten powder in the storage tank 4. The dried tungsten powder enters between the discharge pipe 6 and the top plate 8. At this time, the operator starts the drive motor 13. The drive motor 13 drives the gear ring 11 to rotate through the drive gear 14, which in turn drives the top plate 8 to rotate. The top plate 8 moves along the bottom of the discharge pipe 6. The top plate 8 drives the sleeve plate 20 to move synchronously through the support rod 17, which in turn drives the placing plate 9 to rotate. The placing plate 9 rotates through the clamping plate 18 and the U-shaped frame 10. Multiple rubber sleeves 3 revolve around the center of the feeding cylinder 2, causing the empty rubber sleeve 3 to move directly below the discharge pipe 6. The tungsten powder inside the discharge pipe 6 then enters the rubber sleeve 3 through the first receiving hole on the top plate 8. Subsequently, the drive motor 13 restarts, causing the top plate 8 to move along the bottom of the discharge pipe 6, sealing the bottom of the discharge pipe 6 with its top. The rubber sleeve 3 containing tungsten powder moves away from the discharge pipe 6, while another empty rubber sleeve 3 moves directly below the discharge pipe 6. Thus, with the drive motor... The intermittent rotation of gear 14 enables continuous feeding of tungsten powder, preventing powder leakage. Simultaneously, the feeding tray 9, via the frame-shaped slide 21, drives the moving plate 24 between the two racks 23 to perform circular motion. This causes the guide rod 26 at the bottom of the moving plate 24 to move along the first arc-shaped groove on the fixed plate 28. When the guide rod 26 enters the inclined groove on the fixed plate 28, its movement causes the moving plate 24 to move along the outer side of the frame-shaped slide 21. The moving plate 24 then drives the two symmetrical... The rack 23 moves synchronously, causing the rack 23 to drive the driven gear 22 to rotate. The driven gear 22 then drives the clamping plate 18 to swing through the rotating rod 19, causing the clamping plate 18 to move away from the rubber sleeve 3. The operator can then take out the rubber sleeve 3 containing tungsten powder from the feeding port of the feeding cylinder 2. Finally, the operator places the rubber sleeve 3 containing tungsten powder on the vibrating platform 7 and starts the vibrating platform 7 to vibrate and compact the tungsten powder in the rubber sleeve 3, thereby achieving the effect of continuous powder receiving and improving the production efficiency of tungsten rods.
