Description

Technical Field

[0001] This utility model relates to the field of gear forging technology, specifically to a high-efficiency gear forging equipment. Background Technology

[0002] Powder metallurgy gear manufacturing can minimize material waste by precisely controlling the amount of powder used and the forming process. Compared with traditional cutting, it does not require a lot of cutting to remove excess material, and the material utilization rate can reach more than 90%. The main process is to press the powder into shape, sinter it to form a gear, and finally polish it.

[0003] Existing equipment for gear forging using powder metallurgy lacks a buffer device during the pressing step. When pressing the powder, the pressing force is applied instantaneously, and the powder cannot be evenly distributed under the force. This results in defects in the internal structure of the pressed gear, with inconsistent density in different parts, making the gear relatively fragile. Furthermore, the pressed gear only relies on the limited bonding force between the powder particles to maintain its shape. During subsequent handling and storage, it is extremely easy to break due to slight bumps. This not only affects the yield and quality of the gears but also delays the production efficiency. Summary of the Invention

[0004] In view of the problems existing in the current high-efficiency gear forging equipment, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a high-efficiency gear forging equipment, which solves the problem that existing gear forging equipment lacks a buffer device during the pressing step, which easily leads to uneven dispersion of powder under force, and the pressed gears are easily broken, affecting the yield and quality of gears, and also delaying the production efficiency of gears.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-efficiency gear forging equipment includes a chamber, with multiple hydraulic spring buffer cylinders fixedly connected to the bottom of the chamber cavity, a pressing table fixedly connected to the top of the multiple hydraulic spring buffer cylinders, multiple gear mold slots opened on the top of the pressing table, a central positioning rod fixedly connected to each gear mold slot, a gear-shaped top plate slidably connected to each gear mold slot, and an ejection mechanism fixedly connected to the multiple gear-shaped top plates in the cavity of the pressing table.

[0008] Both ends of the top of the hopper are fixedly connected to U-shaped seats. The top of each U-shaped seat is fixedly connected to a hydraulic cylinder and a stirring device assembly, respectively. One end of the hydraulic cylinder passes through the corresponding U-shaped seat and is fixedly connected to a buffer chamber. A heating unit is fixedly connected to the cavity of the buffer chamber through a buffer mechanism. Multiple pressing heads are fixedly connected to the bottom output end of the heating unit. Each pressing head corresponds to the position of the gear mold groove. A cylinder is fixedly connected to the cavity of one end of the pressing table. The other end of the cylinder passes through the side wall of the pressing table and is fixedly connected to a loading and unloading slide box device. A feeding assembly is fixedly connected between the loading and unloading slide box device and the stirring device assembly.

[0009] Preferably, the ejection mechanism includes an electric push rod, a support plate, a U-shaped rod, and a sliding hole. The electric push rod is fixedly connected to the cavity of the pressing table, and the other end of the electric push rod is fixedly connected to the support plate. Multiple U-shaped rods are fixedly connected to the top of the support plate. Sliding holes are opened at both ends of the bottom of each gear mold groove. The two ends of the U-shaped rod pass through the sliding holes and are fixedly connected to the bottom ends of the gear-shaped top plate.

[0010] Preferably, the buffer mechanism includes a spring-hydraulic buffer, a first positive magnetic plate, and a second positive magnetic plate. Multiple spring-hydraulic buffers are fixedly connected between the heating unit device and the side wall of the buffer chamber. The top of the heating unit device is fixedly connected to the first positive magnetic plate, and the top of the cavity of the buffer chamber is fixedly connected to the second positive magnetic plate.

[0011] Preferably, the top two ends of the stirring device assembly are respectively fixedly connected to a metal powder inlet and a thermosetting adhesive inlet.

[0012] Furthermore, the feeding assembly includes a pump body and a feeding pipe. The pump body is fixedly connected to the output end of the stirring device assembly, and the output end of the pump body is fixedly connected to the feeding pipe.

[0013] Preferably, the inner end walls of the loading and unloading slide box device are fixedly connected with shovel plates, and the loading and unloading slide box device and the shovel plates are slidably connected to the surface of the pressing table.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model utilizes a pressing platform set on top of multiple hydraulic spring buffer cylinders to provide initial buffering, effectively reducing the instantaneous impact force during pressing. The spring hydraulic buffer set in the buffer chamber, combined with the first and second positive magnetic plates with the same magnetic poles repelling each other, further enhances the buffering effect, ensuring that the powder is evenly stressed during the pressing head's impact. At the same time, the heating unit can preheat the pressing head to realize the hot pressing process. After the powder mixed with thermosetting adhesive particles is formed, the gear strength and deformation resistance are greatly improved. This solves the problems of uneven powder stress and easy gear breakage during traditional equipment pressing, significantly improving the gear yield and quality.

[0016] 2. This utility model utilizes multiple gear mold slots and a central positioning rod set on the pressing table to precisely match the pressing head, thereby achieving accurate powder pressing and molding. A support plate set at one end of the electric push rod drives the U-shaped rod to move in the sliding hole, and the pressed gear is smoothly ejected through the gear-shaped top plate. The operation is simple and efficient, reduces manual intervention, and greatly improves gear production efficiency.

[0017] 3. This utility model utilizes an inlet for metal powder and thermosetting adhesive located at the top of the mixing device assembly to facilitate raw material injection. A feeding assembly consisting of a pump body and a feeding pipe precisely delivers the mixed powder into the loading and unloading slide box device. Driven by a cylinder, the loading and unloading slide box device not only completes the unloading process, but its body and the shovels at both ends of the cavity also scrape the discharged powder into the gear mold groove, achieving automated material conveying, ensuring continuous production, effectively solving the problems of untimely material conveying and low efficiency in traditional equipment, and comprehensively improving the production efficiency of gear forging equipment.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses a high-efficiency gear forging equipment.

[0027] This utility model provides, for example Figure 1-4 The high-efficiency gear forging equipment shown includes a chamber 1. Multiple hydraulic spring buffer cylinders 2 are fixedly connected to the bottom of the cavity of the chamber 1. A pressing table 3 is fixedly connected to the top of the multiple hydraulic spring buffer cylinders 2. Multiple gear mold slots 4 are opened on the top of the pressing table 3. A central positioning rod 5 is fixedly connected to each gear mold slot 4. A gear-shaped top plate 6 is slidably connected to each gear mold slot 4. An ejection mechanism is provided in the cavity of the pressing table 3 and fixedly connected to the multiple gear-shaped top plates 6.

[0028] U-shaped seats 7 are fixedly connected to both ends of the top of the silo 1. Hydraulic cylinders 8 and stirring device assemblies 9 are fixedly connected to the top of the U-shaped seats 7 respectively. One end of the hydraulic cylinder 8 passes through the corresponding U-shaped seat 7 and is fixedly connected to a buffer chamber 10. A heating unit device 11 is fixedly connected to the cavity of the buffer chamber 10 through a buffering mechanism. Multiple pressing heads 12 are fixedly connected to the bottom output end of the heating unit device 11. Each pressing head 12 corresponds to the position of the gear mold groove 4. A cylinder 13 is fixedly connected to one end of the cavity of the pressing table 3. The other end of the cylinder 13 passes through the side wall of the pressing table 3 and is fixedly connected to a loading and unloading slide box device 14. A feeding assembly 15 is fixedly connected between the loading and unloading slide box device 14 and the stirring device assembly 9. The pressing table 3, which is set on top of multiple hydraulic spring buffer cylinders 2, achieves the first step of buffering during the pressing process. The multiple gear mold grooves 4 and the center positioning rod 5 facilitate the pressing and shaping of powder with the pressing head 12. The gear-shaped top plate 6 is driven by the ejection mechanism. To facilitate the ejection of the pressed gears from each slot, a buffer chamber 10 located at one end of the hydraulic cylinder 8 is used. By pushing downwards, multiple pressing heads 12 pass through the buffer mechanism and perform pressing work on the gear mold slots 4 corresponding to their positions. This ensures that the powder is evenly stressed. Simultaneously, the pressing heads 12 can be preheated by the heating unit device 11 to hot-press the mixed powder. Under hot pressing, the powder mixed with thermosetting adhesive particles can enhance the strength and deformation resistance of the gears. The loading and unloading slide box device 14 located at one end of the cylinder 13 can push the ejected gears towards the discharge port of the chamber for unloading. During the pushing process, the raw materials mixed in the stirring device assembly 9 can be fed into each gear mold slot 4 by the feeding assembly 15. This solves the problem that existing gear forging equipment lacks a buffer device during the pressing step, which easily leads to uneven distribution of powder stress and makes the pressed gears easily breakable, affecting the yield and quality of the gears and delaying the production efficiency of the gears.

[0029] In order to eject the pressed gear, such as Figure 2 As shown, the ejection mechanism includes an electric push rod 16, a support plate 17, U-shaped rods 18, and sliding holes 19. The electric push rod 16 is fixedly connected to the cavity of the pressing table 3. The other end of the electric push rod 16 is fixedly connected to the support plate 17. Multiple U-shaped rods 18 are fixedly connected to the top of the support plate 17. Sliding holes 19 are opened at both ends of the bottom of each gear mold groove 4. The two ends of the U-shaped rods 18 pass through the sliding holes 19 and are fixedly connected to the two ends of the bottom of the gear-shaped top plate 6. By pushing the support plate 17 at one end of the electric push rod 16 upward, the multiple U-shaped rods 18 move in the sliding holes 19, thereby ejecting the pressed gear through the multiple gear-shaped top plates 6.

[0030] To achieve and enhance the buffering effect, such as Figure 2 As shown, the buffer mechanism includes a spring-hydraulic buffer 20, a first positive magnetic plate 21, and a second positive magnetic plate 22. Multiple spring-hydraulic buffers 20 are fixedly connected between the heating unit device 11 and the side wall of the buffer chamber 10. The first positive magnetic plate 21 is fixedly connected to the top of the heating unit device 11, and the second positive magnetic plate 22 is fixedly connected to the top of the cavity of the buffer chamber 10. By using the spring-hydraulic buffers 20, the multiple pressing heads 12 at the bottom are buffered by the heating unit device 11 when moving downward. By using the first positive magnetic plate 21 and the second positive magnetic plate 22, the buffering effect is enhanced by the repulsion of the same magnetic poles through the magnetic plates with the same magnetic field at both ends.

[0031] To facilitate the injection of metal powder and thermosetting adhesive particles into the stirring device assembly 9, such as Figure 1 and 2 As shown, the top two ends of the mixing device assembly 9 are respectively fixedly connected to a metal powder inlet 23 and a thermosetting adhesive inlet 24. By utilizing the metal powder inlet 23 and the thermosetting adhesive inlet 24, it is convenient to inject metal powder and thermosetting adhesive particles into the mixing device assembly 9.

[0032] In order to feed the mixed powder into the loading and unloading sliding box device 14, such as Figure 2 As shown, the feeding assembly 15 includes a pump body 25 and a feeding pipe 26. The pump body 25 is fixedly connected to the output end of the stirring device assembly 9. The output end of the pump body 25 is fixedly connected to the feeding pipe 26. The other end of the feeding pipe 26 is fixedly connected to the top input end of the loading and unloading slide box device 14. By using the feeding assembly 15 composed of the pump body 25 and the feeding pipe 26, it is convenient to feed the mixed powder into the loading and unloading slide box device 14.

[0033] Finally, to facilitate scraping the discharged powder into each gear mold groove 4, such as... Figure 2 and 4 As shown, the side walls at both ends of the cavity of the loading and unloading slide box device 14 are fixedly connected with shovel plates 27. The loading and unloading slide box device 14 and the shovel plates 27 are slidably connected to the surface of the pressing table 3. By using the shovel plates 27, it is easy to scrape the discharged powder into each gear mold groove 4, which is convenient for pressing.
