Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.
[0033] Reference Figure 1 and Figure 2This utility model discloses a forging device for valve body production, comprising a processing platform 1. A servo motor 3 is fixedly connected to one end of the processing platform 1. The servo motor 3 allows a transmission rod 4 to rotate within the processing platform 1. The output end of the servo motor 3 passes through the processing platform 1 and is fixedly connected to the transmission rod 4, which is rotatably connected to the processing platform 1. The transmission rod 4 allows a worm gear 5 to rotate within the processing platform 1. A protective cover 2 is provided around the top of the processing platform 1 to prevent waste material from splashing. A hydraulic cylinder 21 is fixedly connected to the top of the protective cover 2, allowing a connecting plate 29 to slide up and down within the protective cover 2. A disassembly assembly is provided inside the fixing rod 10. A collection component is provided on the side. The top of the fixing rods 10 on both ends are connected to a fixing plate 9 through and slidingly. The fixing plate 9 is connected to the limiting rod 12 through and slidingly. The required structure and components can be connected and fixed by the fixed plate 9. The top of the fixing plate 9 is fixedly connected to a pressure block 13. The pressure block 13 can drive the pressure rod 16 to move closer or further away from each other. One end of the carrying box 26 is connected to a storage box 27 through and slidingly. The collected dust can be discharged to the outside through the storage box 27. The bottom of the second slide rod 17 is provided with an upper mold 19. One end of the first slide rod 14 is provided with a pressure rod 16. The top of the bottom support rod 30 is provided with a lower mold 20. The linkage between the upper mold 19, the lower mold 20 and the pressure rod 16 can extrude and shape the raw material.
[0034] Reference Figure 2 and Figure 3One end of the transmission rod 4 is fixedly connected to a worm gear 5. A bidirectional threaded rod 6 is rotatably connected through the middle of the top of the processing platform 1. One end of the bidirectional threaded rod 6 is fixedly connected to a worm wheel 7, and the worm wheel 7 meshes with the worm gear 5. The output end of the hydraulic cylinder 21 passes through the protective cover 2 and is fixedly connected to a support rod 30. Fixed rods 10 are slidably connected to the inner wall of the support rod 30, and the fixed rods 10 are fixedly connected to the processing platform 1. Nut pairs 8 are threadedly connected to the outer ring of the bidirectional threaded rod 6, and the nut pairs 8 are slidably connected to the processing platform 1. The nut pairs 8 are fixedly connected to the fixed rods 10. By rotating the worm gear 5, the worm wheel 7 rotates, which in turn rotates the bidirectional threaded rod 6, causing the nut pairs 8 to slide on the processing platform 1. This prevents the device from shifting during processing, thus ensuring the dimensional accuracy and shape consistency of the valve shell. The disassembly assembly includes the first... Spring 11, one end of each spring 11 is fixedly connected to a limiting rod 12, and the limiting rod 12 is slidably connected to the support rod 30. By allowing the limiting rod 12 to slide into the fixed rod 10, the first spring 11 is compressed, thus adapting to the production of valve shells of different sizes and shapes. One end of each pressure block 13 is slidably connected to a first slide rod 14, and one end of the outer ring of each first slide rod 14 is fitted with a first damping spring 15. The top and four sides of the connecting plate 29 are slidably connected to a second slide rod 17, and one end of the outer ring of each second slide rod 17 is fitted with a second damping spring 18. By sliding the first slide rod 14, the first damping spring 15 is compressed, and then by sliding the second slide rod 17, the second damping spring 18 is compressed, thus ensuring that the raw material being processed is subjected to uniform force during the molding process, thereby improving product quality.
[0035] Reference Figure 1 and Figure 4 The bottom of the top fixing rod 10 is fixedly connected to a connecting plate 29. The collection assembly includes a through tube 24, which is fixedly connected to both ends of the other side of the processing platform 1. An air pump 25 is installed at one end of the through tube 24. A sealing plate 22 is slidably connected to the top side of the protective cover 2. A pull rope 23 is fixedly connected to one side of the sealing plate 22, and one end of the pull rope 23 is fixedly connected to the connecting plate 29. By moving the connecting plate 29 up and down, the pull rope 23 is pulled, thereby allowing the sealing plate 22 to slide inside the protective cover 2. This maintains the sealing of the mold during the forging process and prevents impurities from entering. At the same time, the door opens automatically during cleaning for easy operation. A carrier box 26 is fixedly connected to the middle of one side of the processing platform 1. A fan 28 is fixedly connected to one side of the carrier box 26. By starting the air pump 25, gas is sprayed out of the through tube 24. At the same time, driven by the fan 28, the processing platform 1 and the working environment are kept clean, reducing the equipment failure rate and extending the service life of the equipment.
[0036] Working principle: By allowing the limiting rod 12 to slide into the fixing rod 10, the first spring 11 is compressed, causing the two fixing plates 9 to slide into the fixing rods 10 on both sides. Then, due to the rebound of the first spring 11, the limiting rod 12 slides out of the fixing rod 10 and into the fixing plate 9, thus fixing the fixing plate 9 onto the nut assembly 8. This fixes the required pressure rod 16 in the designated position. Then, the support rod 30 slides into the top fixing rod 10, and again, due to the rebound of the first spring 11, the limiting rod 12 slides into the support rod 30, thus... The designated connecting plate 29 is fixed in the designated position to limit and fix the required upper mold 19. Then, the bottom support rod 30 is slid into the bottom fixing rod 10. Subsequently, the rebound of the first spring 11 limits and fixes the required lower mold 20. Then, the downward movement of the connecting plate 29 brings the upper mold 19 into contact with the lower mold 20. The connecting plate 29 continues to move downward, causing the second slide rod 17 to slide on the connecting plate 29, thereby compressing the second damping spring 18. Subsequently, the rebound of the second damping spring 18... To provide the necessary buffering capacity between the upper and lower molds, the worm gear 5 rotates, and through the meshing connection between the worm gear 5 and the worm wheel 7, the worm wheel 7 rotates within the processing platform 1, causing the bidirectional threaded rod 6 to rotate within the processing platform 1. This brings the two nut pairs 8 closer together, allowing the pressure rod 16 to slide into the upper and lower molds for further processing of the raw material. Subsequently, through the contact between the pressure rod 16 and the raw material, the first sliding rod 14 slides within the pressure block 13, thereby compressing the first damping spring 15. Then, through the first damping spring 15... The rebound provides the necessary cushioning to the pressure rod 16. Then, when the connecting plate 29 moves downward, it pulls the rope 23, causing the sealing plate 22 to slide within the protective cover 2. Subsequently, the air pump 25 is activated, causing the through tube 24 to blow up the waste material remaining in the lower mold 20. At the same time, the blower 28 is activated to suck the blown waste material to a designated location, where it is then filtered by the filter screen shown in the figure. The waste material generated during processing is collected into the carrier box 26, and then discharged from the carrier box 26 by the sliding of the collection box 27.
