Description

Technical Field

[0001] This invention relates to the field of gear forging technology, specifically to a forging equipment for gear blank forming and processing. Background Technology

[0002] Gears are mechanical components that transmit motion and power through continuous meshing of gears on their rims. Gears are widely used in the machinery industry, and the processing quality of gears is a key factor restricting the improvement of product level. As industry becomes more and more developed, the demand for gears is also increasing. Gear blanks are blank products that have undergone preliminary forging but have not undergone deep processing. Generally, heated gear blank raw materials need to be placed into a special mold for pressure forging into a wheel-shaped structure with multiple sets of annular grooves on the surface.

[0003] During the forging process of gear blanks, some residues will detach from the gear blanks due to pressure and cooling and adhere to the mold cavity. In order to ensure the forging quality, the residues need to be removed during the forging intervals. This is generally done manually. However, some residues adhere to the upper mold, limiting the viewing angle and making it difficult to clean quickly. There is also a risk that personnel may be accidentally burned or crushed during the cleaning process. Summary of the Invention

[0004] The purpose of this invention is to provide a forging equipment for gear blank forming and processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A forging machine for forming gear blanks includes a housing, a frame fixedly connected to the housing, a servo hydraulic cylinder fixedly connected to the frame, and further includes: An upper forging structure connected to the moving end of a servo hydraulic cylinder; A forging structure for conversion connected to a chassis includes a first motor connected to the chassis, the output shaft of the first motor being fixedly connected to a rotary table rotatably mounted inside the chassis, two sets of lower die bodies being symmetrically mounted on the rotary table, a rectangular through slot being provided inside the rotary table, a rectangular block being coaxially fixedly connected to the rotary table, two sets of first electric telescopic rods being fixedly connected to the chassis, the two sets of first electric telescopic rods being jointly fixedly connected to a limiting frame movably connected to the rectangular block, and the limiting frame being slidably connected to the chassis; A scraping and cleaning structure installed inside a chassis, the scraping and cleaning structure including a lifting and rotating assembly connected to the chassis, a scraping and extrusion assembly mounted on the lifting and rotating assembly, the scraping and extrusion assembly being located below the rotary table, the scraping and extrusion assembly being used to perform residue removal and cleaning operations on the upper forging structure and the lower die body.

[0006] As a further improvement of the present invention: the upper forging structure includes a fixed sleeve fixedly connected to the moving end of the servo hydraulic cylinder, the fixed sleeve is detachably connected to a connector, and an upper die body adapted to the shape of the lower die body is fixedly installed at the lower end of the connector. The forging cavity of the upper die body and the forging cavity of the lower die body have the same structure.

[0007] As a further improvement of the present invention: the lifting and rotating assembly includes two sets of track frames fixedly installed inside the chassis. The track frames are fixedly connected to a second electric telescopic rod. The moving end of the second electric telescopic rod is fixedly connected to a pressure sensor. The pressure sensor is fixedly connected to a synchronization frame that is slidably connected to the track frames. The synchronization frame is fixedly connected to multiple sets of ball sleeves. The ball sleeves are rotatably connected to balls. A second motor is fixedly installed at the bottom of the chassis. The output shaft of the second motor is fixedly connected to an umbrella-shaped disk. The umbrella-shaped disk is coaxially fixedly connected to a sleeve. The sleeve is slidably connected to a prism. The prism is connected to a scraping assembly. The prism is fixedly connected to two sets of supports. The two sets of supports are jointly fixedly connected to a ring that is slidably connected to the outer wall of the sleeve. The ring abuts against multiple sets of balls.

[0008] As a further improvement of the present invention: an isolation plate that is slidably connected to the track frame is fixedly installed on the synchronization frame, the isolation plate is slidably connected to the outer wall of the second electric telescopic rod, and a lower pressure frame is fixedly connected to the synchronization frame, the lower pressure frame being rotatably connected to the ring body.

[0009] As a further improvement of the present invention: the scraping assembly includes a base fixedly connected to the top of the prism, a scraper seat is assembled on the base, the scraper seat is hinged to a swing arm, the swing arm is fixedly connected to a spring, the spring is fixedly connected to the inner wall of the scraper seat, and the swing arm is fixedly connected to a friction wheel.

[0010] As a further improvement of the present invention: a maintenance cover is movably installed on the chassis.

[0011] As a further improvement of the present invention: the chassis assembly is connected to a protective cover, and the rectangular block, the first electric telescopic rod, and the limiting frame are all set in the space enclosed by the protective cover and the chassis.

[0012] Compared with the prior art, the beneficial effects of the present invention are: The gear blank is placed into the upper die body of the forging die cavity. Driven by a servo hydraulic cylinder, the upper forging structure moves down to the lower die body, causing the lower die body to close with the upper forging structure to forge the gear blank. During this process, the first motor restricts the rotation of the rotary table, and the limit frame restricts the rotation of the rectangular block to prevent the lower die body from driving the rotary table to rotate due to pressure. Then, the servo hydraulic cylinder drives the upper forging structure to move up and detach from the lower die body. After the forged gear blank is removed from the lower die body, the operator starts the first electric telescopic rod through the control panel, causing the first electric telescopic rod to drive the limit frame to detach from the rectangular block. The first motor drives the rotary table to rotate, causing the rectangular through slot to rotate to a vertical position, with one end of the rectangular through slot facing the upper forging structure and the other end facing the scraper. The extrusion assembly is set up, and then a servo hydraulic cylinder drives the upper forging structure to move downwards and pass through the rectangular through slot. Meanwhile, a lifting and rotating assembly drives the scraping and extrusion assembly to rise and rotate, allowing the scraping and extrusion assembly to clean the upper forging structure. Afterwards, the lifting and rotating assembly drives the scraping and extrusion assembly to reset, and the servo hydraulic cylinder drives the upper forging structure to reset and move upwards. A first motor drives the rotary table to rotate, so that the forging cavity of the used lower die body faces the scraping and extrusion assembly. The lifting and rotating assembly drives the scraping and extrusion assembly to rise and rotate, cleaning the lower die body. During this process, the gear blank is placed into another set of lower dies. The first motor restricts the rotation of the rotary table, and the limit frame restricts the rotation of the rectangular block. The upper forging structure forges the gear blank, achieving simultaneous cleaning and processing, thus improving the processing efficiency of this invention. This invention achieves automated cleaning and forging operations by cooperating with the upper forging structure, the shifting forging structure, and the scraping and cleaning structure, saving manpower. Furthermore, some cleaning and forging operations are performed simultaneously, improving the overall processing efficiency and operational safety of this invention. Attached Figure Description

[0027] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0028] Example 1, see Figures 1 to 13 As shown, a forging equipment for gear blank forming includes a housing 1, a control console 2 fixedly connected to the housing 1, a frame 3 fixedly connected to the housing 1, a servo hydraulic cylinder 4 fixedly connected to the frame 3, the servo hydraulic cylinder 4 being disposed above the housing 1, and further includes: The upper forging structure 5 is connected to the moving end of the servo hydraulic cylinder 4; The forging structure 6 is connected to the housing 1. The forging structure 6 includes a first motor 7 connected to the housing 1. The output shaft of the first motor 7 is fixedly connected to a rotary table 8 rotatably installed inside the housing 1. Two sets of lower die bodies 9 are symmetrically installed on the rotary table 8. A rectangular through slot 10 is opened in the rotary table 8. The opening size of the rectangular through slot 10 is larger than the outer contour size of the upper forging structure 5. A rectangular block 11 is fixedly connected to the rotary table 8 coaxially. Two sets of first electric telescopic rods 12 are fixedly connected to the housing 1. The two sets of first electric telescopic rods 12 are fixedly connected to a limiting frame 13 that is movably connected to the rectangular block 11. The limiting frame 13 is slidably connected to the housing 1. A scraping and cleaning structure 14 is installed inside the chassis 1. The scraping and cleaning structure 14 includes a lifting and rotating assembly 15 connected to the chassis 1. A scraping and extrusion assembly 16 is installed on the lifting and rotating assembly 15. The scraping and extrusion assembly 16 is located below the rotary table 8. The scraping and extrusion assembly 16 is used to perform residue removal and cleaning operations on the upper forging structure 5 and the lower die body 9.

[0029] The gear blank is placed into the upper die body 9 of the forging die cavity. Driven by the servo hydraulic cylinder 4, the upper forging structure 5 moves down to the lower die body 9, so that the lower die body 9 and the upper forging structure 5 are closed to forge the gear blank. During this process, the first motor 7 restricts the rotation of the rotary table 8 and the limit frame 13 restricts the rotation of the rectangular block 11 to prevent the lower die body 9 from driving the rotary table 8 to rotate due to pressure. Then, the servo hydraulic cylinder 4 drives the upper forging structure 5 to move up and separate from the lower die body 9. After the forged gear blank is removed from the lower die body 9, the operator starts the first electric telescopic rod 12 through the control console 2, so that the first electric telescopic rod 12 drives the limit frame 13 to separate from the rectangular block 11. The first motor 7 drives the rotary table 8 to rotate, so that the rectangular through slot 10 rotates to a vertical position, with one end of the rectangular through slot 10 facing the upper forging structure 5 and the other end facing the scraper. Component 16 is set up, and then the servo hydraulic cylinder 4 drives the upper forging structure 5 to move down and pass through the rectangular through slot 10. The lifting and rotating component 15 drives the scraping component 16 to rise and rotate, so that the scraping component 16 can clean the upper forging structure 5. Then the lifting and rotating component 15 drives the scraping component 16 to reset, the servo hydraulic cylinder 4 drives the upper forging structure 5 to reset and move up, and the first motor 7 drives the rotary table 8 to rotate, so that the forging cavity of the used lower die 9 faces the scraping component 16. The lifting and rotating component 15 drives the scraping component 16 to rise and rotate to clean the lower die 9. During this period, the gear blank is placed in another set of lower die 9. The first motor 7 restricts the rotation of the rotary table 8 and the limit frame 13 restricts the rotation of the rectangular block 11. The upper forging structure 5 forges the gear blank, realizing that cleaning and processing are carried out at the same time, improving the processing efficiency of the present invention. This invention achieves automated cleaning and forging operations by cooperating with the upper forging structure 5, the shift forging structure 6, and the scraping and cleaning structure 14, saving manpower. Furthermore, some cleaning and forging operations can be performed simultaneously, thereby improving the overall processing efficiency and operational safety of this invention.

[0030] In one embodiment, the upper forging structure 5 includes a fixed sleeve 17 fixedly connected to the moving end of the servo hydraulic cylinder 4. A connector 18 is detachably connected to the fixed sleeve 17. An upper die body 19, whose shape is adapted to that of the lower die body 9, is fixedly mounted at the lower end of the connector 18. The forging cavity of the upper die body 19 has the same structure as that of the lower die body 9. By removing the connector 18 from the fixed sleeve 17, the upper die body 19 can be disassembled separately, facilitating its disassembly and replacement.

[0031] In one embodiment, the lifting and rotating assembly 15 includes two sets of track frames 20 fixedly installed inside the housing 1. Each track frame 20 is fixedly connected to a second electric telescopic rod 21. A pressure sensor 22 is fixedly connected to the moving end of the second electric telescopic rod 21. The pressure sensor 22 is fixedly connected to a synchronization frame 23 slidably connected to the track frame 20. Multiple sets of ball sleeves 24 are fixedly connected to the synchronization frame 23. A ball 25 is rotatably connected to each ball sleeve 24. A second motor 26 is fixedly installed at the bottom of the housing 1. The second motor 26... An umbrella-shaped disk 27 is fixedly connected to the output shaft. A sleeve 28 is coaxially fixedly connected to the umbrella-shaped disk 27. A prism 29 is slidably connected to the sleeve 28. A baffle 41 for guiding the residue is fixedly connected to the prism 29. The baffle 41 is positioned above the sleeve 28 to prevent the residue from falling into the gap between the sleeve 28 and the prism 29. The prism 29 is connected to the scraping assembly 16. Two sets of supports 30 are fixedly connected to the prism 29. The two sets of supports 30 are jointly fixedly connected to a ring 31 that is slidably connected to the outer wall of the sleeve 28. The ring 31 abuts against multiple sets of spheres 25. The second electric telescopic rod 21 drives the synchronous frame 23 to move via the pressure sensor 22. The synchronous frame 23 drives the ball sleeve 24 to move, and the ball sleeve 24 drives the ball 25 to move. As the ball 25 pushes the ring 31 to rise, the ring 31 drives the prism 29 to rise via the bracket 30. The prism 29 slides relative to the sleeve 28, thereby increasing the height of the scraping assembly 16. The pressure sensor 22 measures the transmitted force in real time. The control console 2 uses the extension and retraction of the second electric telescopic rod 21 and the force value measured by the pressure sensor 22 to determine the lifting and lowering of the synchronous frame 23, and thus obtain the lifting and lowering of the scraping assembly 16. If the scraping assembly 16 directly presses on the residue generated by forging, the pressure sensor 22 will abnormally increase the value of the second electric telescopic rod 21 before it reaches the preset extension and retraction amount. At this time, the retraction of the second electric telescopic rod 21 is stopped, and the second electric telescopic rod 21 extends to make The scraping assembly 16 descends and detaches from the residue. Then, the second motor 26 drives the umbrella-shaped disk 27 to rotate. The umbrella-shaped disk 27 drives the sleeve 28 to rotate. The sleeve 28 drives the prism 29 to rotate. The prism 29 drives the ring 31 to rotate through the bracket 30. The rotating ring 31 is supported by the ball 25. At the same time, the prism 29 drives the scraping assembly 16 to rotate. The second electric telescopic rod 21 drives the pressure sensor 22 to rise again until the scraping assembly 16 completely contacts the lower die 9 or the upper forging structure 5. Then, the second motor 26 drives the umbrella-shaped disk 27 to rotate. The umbrella-shaped disk 27 drives the sleeve 28 to rotate. The sleeve 28 drives the prism 29 to rotate. The prism 29 drives the ring 31 to rotate through the bracket 30. The rotating ring 31 is supported by the ball 25. At the same time, the prism 29 drives the scraping assembly 16 to rotate, so that the rotating scraping assembly 16 cleans the residue on the lower die 9 or the upper forging structure 5. The residue falls off under the action of gravity.

[0032] In one embodiment, an isolation plate 32, which is slidably connected to the track frame 20, is fixedly installed on the synchronization frame 23. The isolation plate 32 is slidably connected to the outer wall of the second electric telescopic rod 21. A lower pressure frame 33 is fixedly connected to the synchronization frame 23, and the lower pressure frame 33 is rotatably connected to the ring body 31. The isolation plate 32 is used to prevent residue from contacting the moving part of the second electric telescopic rod 21, thus preventing residue from hindering the extension and retraction of the second electric telescopic rod 21. If the prism 29 gets stuck with the sleeve 28 when it falls, the lower pressure frame 33 moves down as the synchronization frame 23 moves down, pressing the ring body 31. The ring body 31 then moves the prism 29 down through the bracket 30 to ensure that the prism 29 falls smoothly.

[0033] In one embodiment, the scraping assembly 16 includes a base 34 fixedly connected to the top of the prism 29. A scraper seat 35 is mounted on the base 34. A swing arm 36 is hinged to the scraper seat 35. A spring 37 is fixedly connected to the swing arm 36. The spring 37 is fixedly connected to the inner wall of the scraper seat 35. A friction wheel 38 is fixedly connected to the swing arm 36. As the prism 29 drives the seat 34 to rotate, the seat 34 drives the scraper seat 35 to rotate. The scraper seat 35 scrapes away the residue and drives the swing arm 36 to move. Under the action of the spring 37, the swing arm 36 keeps the friction wheel 38 in close contact with the center surface of the lower die body 9 or the upper forging structure 5. As the seat 34 rises and falls, the friction wheel 38, which is in contact with the lower die body 9 or the upper forging structure 5, impacts or rubs the residue on the center surface of the lower die body 9 or the upper forging structure 5 while rotating with the swing arm 36. This cleans the residue in the center area that the scraper seat 35 cannot clean, and prevents the scraper seat 35 from continuously pressing on the lower die body 9 or the upper forging structure 5. The residue on the central surface of the die body 9 or the upper forging structure 5 improves cleaning efficiency and solves the problem of dead corners in the center of the rotating cleaning. In addition, the elasticity of the spring 37 can effectively buffer the impact force on the friction wheel 38 during the cleaning process, thereby extending the service life of the scraping assembly 16. Furthermore, the modular installation method of the scraper seat 35 is easy to disassemble and replace. Operators can quickly replace different specifications of scraper seats 35 according to actual needs to adapt to different types of cleaning tasks. This modular design not only improves the versatility of the equipment, but also significantly reduces maintenance costs and time consumption.

[0034] In one embodiment, a maintenance cover 39 is movably mounted on the chassis 1. The maintenance cover 39 facilitates the cleaning of debris inside the chassis 1.

[0035] Example 2, based on Example 1, see [link / reference] Figure 1 , Figure 2 , Figure 5The chassis 1 is equipped with a protective cover 40. The rectangular block 11, the first electric telescopic rod 12, and the limiting frame 13 are all located within the space enclosed by the protective cover 40 and the chassis 1. By setting up the protective cover 40, personnel are prevented from accidentally touching the rectangular block 11, the first electric telescopic rod 12, and the limiting frame 13 during operation, thus protecting personnel safety.

[0036] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention.
