Description

Technical Field

[0001] This invention belongs to the field of axle machining technology, specifically an environmentally friendly axle forging device. Background Technology

[0002] The automotive half-shaft is a crucial component connecting the engine and wheels. Located at the end of the transmission system, it is responsible for altering the speed and torque from the gearbox. Automotive half-shafts are typically manufactured using a forging process. The metal billet, after being burned, is subjected to pressure by a forging press, causing plastic deformation to achieve excellent mechanical properties and a specific shape and size. In existing technologies, after the final forging step, the half-shaft often requires a cooling process. Natural cooling is commonly used, but this method offers no advantages beyond low cost. Since half-shafts require mass production, the efficiency of cooling is critical. Existing improvements utilize water-cooled spray for cooling, but this method's cooling speed is still limited by the contact time and area between the workpiece and the air / liquid, failing to achieve ideal results. Therefore, this invention addresses these potential shortcomings by providing an environmentally friendly half-shaft forging device. Summary of the Invention

A device located inside the water storage ring is rotatably mounted on the top of the forging die. The rotating ring on the side has multiple sets of inclined plates fixedly connected to its top. Multiple sets of sealing cylinders are fixedly installed on the front side of the top of the worktable. The sealing cylinder has a sealing block and a second spring inside its sealing sleeve. The piston rod is sealed and inserted into the sealing cylinder and elastically connected to the second spring. A connecting cylinder is fixedly connected to the left rear side of the inner ring surface of the worktable. A sealing column is fixedly installed on the inner wall of the worktable. The connecting cylinder has a connecting pipe and a third spring inside its sealing sleeve. The sealing column extends to the inner wall of the connecting cylinder and can be interference-fitted with the inner wall of the connecting pipe. An external gear ring is installed on the inner ring surface of the worktable. Gears are installed on the outer surface of the forging die. A water inlet mechanism is installed on the rear side of the top of the worktable.

[0005] In a preferred embodiment of the present invention, the bracket is fixedly installed on the front side of the top of the workbench, the hydraulic cylinder is installed on the top of the bracket, the motor is installed on the bottom of the bracket, the sealing block is located at the bottom of the inner wall of the sealing cylinder, and the bottom of the sealing block abuts against and seals with the cooling water located in the inner cavity of the workbench.

[0006] In a preferred embodiment of the present invention, the forging hammer is located at 0° in the inner annular surface of the workbench, the sealing column is located at 120° in the inner cavity of the workbench, the sealing column is coaxially distributed with the connecting cylinder, and the gear meshes with the external gear ring.

[0007] As a preferred embodiment of the present invention, the water inlet mechanism includes a one-way plate fixedly installed on the rear side of the top of the workbench, and the outer surface of the water inlet pipe is movably sleeved with a one-way plate located in the inner cavity of the workbench. One end of the one-way plate is elastically connected to the top of the inner cavity of the workbench, and the other end of the one-way plate is elastically connected with a spring.

[0008] As a preferred embodiment of the present invention, the inner ring surface of the workbench is designed in a stepped manner, and the bottom of the forging die abuts against the inner side of the top of the workbench.

[0009] As a preferred embodiment of the present invention, the number of jet nozzles is eight groups, the axis of each group of jet nozzles points to the axis of the forging die, and the inclined plate is designed to be inclined and directly opposite the axis of the jet nozzle.

[0010] As a preferred embodiment of the present invention, when any group of forging dies moves to the 120° position in the inner ring of the workbench, the axis of the water receiving pipe and the connecting pipe that have moved to this position coincides.

[0011] As a preferred embodiment of the present invention, a sealing ring 1 is fixedly sleeved on the outer surface of the water receiving pipe, and a sealing ring 2 is fixedly sleeved on the outer surface of the connecting pipe. Both the sealing ring 1 and the sealing ring 2 are made of rubber blocks.

[0012] In a preferred embodiment of the present invention, the connecting pipe does not abut against one end of the sealing ring in the initial position, and the sealing post is sealed and inserted into the inner wall of the connecting pipe at this time.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. This device has been redesigned to achieve dual cooling functions of air and liquid cooling for forged workpieces, which can greatly improve the cooling efficiency of the device. A hydraulic cylinder drives the connecting plate and piston column to move downward, and the compression springs apply pressure to the sealing blocks, pushing the cooling water in the inner cavity of the worktable to gather inside the connecting cylinder. When the forging mold carrying the workpiece that has completed the forging process and the water receiving pipe move to the cooling zone, the connecting pipe moves towards one end of the water receiving pipe under the strong water pressure, and the sealing column disengages and abuts against the water receiving pipe, connecting the inner cavity of the worktable and the inner cavity of the water storage ring. The high-pressure cooling water squeezed by the piston column and sealing blocks is ejected through the nozzle and pushes the inclined plate to rotate, generating wind. At the same time, the cooling water increases the contact area with the workpiece by impacting the inclined plate. Combined with air cooling, the cooling capacity of the workpiece is greatly improved.

[0015] 2. This device is also equipped with a gear located on the outer surface of the forging die and an outer gear ring located on the inner ring surface of the worktable that mesh with each other. When the motor drives the mounting ring and the forging die to revolve, the forging die can rotate on its own. This design allows the workpiece located in the mold cavity of the forging die to dynamically adjust its position through relative rotation with the forging die. After forging, a large amount of waste and debris will be generated. Through the centrifugal force generated by the rotation, these impurities can be "thrown" to the surrounding area, so as not to affect the water cooling of the workpiece.

[0016] 3. This device is also equipped with a connecting cylinder located in the cooling zone, which realizes the automatic opening and closing of the cooling water flow. When the device is forging, the hydraulic cylinder drives the forging hammer and piston column to move down, and generates high-pressure water inside the connecting cylinder. The water is sealed and inserted into the inner wall of the connecting pipe through the sealing column, forming a seal. This pushes the connecting pipe to move away from the sealing column, opening the connecting pipe. At the same time, the spring three is compressed. When the sealing column leaves the inner wall of the connecting pipe, the connecting pipe is just abutted against one end of the water inlet pipe, forming a seal, thus realizing the opening of the cooling water. When the hydraulic cylinder moves up and resets, the connecting pipe, which has lost the water pressure, is reset under the action of the spring three and re-sealed and inserted into the sealing column, automatically closing the water outlet. This design helps to save cooling water resources. Attached Figure Description

[0027] 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.

[0028] like Figures 1 to 9 As shown, this embodiment of the invention provides an environmentally friendly half-shaft forging device, including a workbench 1, a support 2, a motor 3, and a hydraulic cylinder 4. A connecting plate 5 is installed at the telescopic end of the hydraulic cylinder 4. A piston column 6 and a forging hammer 16 are fixedly installed at the bottom of the connecting plate 5. A connecting frame 10 is fixedly installed on the output shaft of the motor 3. Three sets of mounting rings 11 are fixedly installed on the outer side of the connecting frame 10. A forging die 12 is rotatably mounted inside the mounting rings 11. The inner cavity of the workbench 1 is filled with cooling water. A water storage ring 14 is fixedly installed on the top of the forging die 12. Multiple sets of spray nozzles 17 are opened on the inner ring surface of the water storage ring 14. A water inlet pipe 20 is fixedly installed on the outer ring surface of the water storage ring 14. A rotating ring located inside the water storage ring 14 is rotatably mounted on the top of the forging die 12. 18. Multiple sets of inclined plates 19 are fixedly connected to the top of the rotating ring 18. Multiple sets of sealing cylinders 7 are fixedly installed on the front side of the top of the worktable 1. The sealing cylinder 7 has a sealing block 22 and a spring 23 inside the sealing sleeve. The piston column 6 is sealed and inserted into the sealing cylinder 7 and elastically connected to the spring 23. A connecting cylinder 15 is fixedly connected to the left rear side of the inner ring surface of the worktable 1. A sealing column 24 is fixedly installed on the inner wall of the worktable 1. The connecting cylinder 15 has a connecting pipe 25 and a spring 26 inside the sealing sleeve. The sealing column 24 extends to the inner wall of the connecting cylinder 15 and can be interference-fitted with the inner wall of the connecting pipe 25. An external gear ring 8 is installed on the inner ring surface of the worktable 1. A gear 13 is installed on the outer surface of the forging mold 12. A water inlet mechanism 9 is installed on the rear side of the top of the worktable 1.

[0029] This device has been redesigned to achieve dual cooling functions of air and liquid cooling for forged workpieces, which can greatly improve the cooling efficiency of the device. A hydraulic cylinder 4 drives the connecting plate 5 and piston column 6 to move downward, and the compression spring 23 applies pressure to the sealing block 22, pushing the cooling water in the inner cavity of the worktable 1 to gather inside the connecting cylinder 15. When the forging mold 12 with the workpiece that has completed the forging process and the water receiving pipe 20 move to the cooling zone, the connecting pipe 25 moves towards one end of the water receiving pipe 20 under the strong water pressure, and the sealing column 24 disengages and abuts against the water receiving pipe 20, connecting the inner cavity of the worktable 1 and the inner cavity of the water storage ring 14. The high-pressure cooling water flow squeezed by the piston column 6 and the sealing block 22 is ejected through the nozzle 17 and pushes the inclined plate 19 to rotate, generating wind. At the same time, the cooling water increases the contact area with the workpiece by impacting the inclined plate 19. Combined with air cooling, the cooling capacity of the workpiece is greatly improved.

[0030] This device is also equipped with a gear 13 located on the outer surface of the forging die 12 and an outer gear ring 8 located on the inner ring surface of the worktable 1, which mesh with each other. When the motor 3 drives the mounting ring 11 and the forging die 12 to revolve, the forging die 12 can rotate. This design allows the workpiece located in the mold cavity of the forging die 12 to achieve dynamic position adjustment through relative rotation with the forging die 12. After forging, a large amount of waste and debris will be generated. Through the centrifugal force generated by rotation, these impurities can be "thrown" to the periphery, so as not to affect the water cooling of the workpiece.

[0031] This device is also equipped with a connecting cylinder 15 located in the cooling zone, which realizes the automatic opening and closing of the cooling water flow. When the device is forging, the hydraulic cylinder 4 drives the forging hammer 16 and piston column 6 to move down, and generates high pressure water inside the connecting cylinder 15. The water is sealed and inserted into the inner wall of the connecting pipe 25 through the sealing column 24 to form a seal. The connecting pipe 25 is pushed to move away from the sealing column 24, opening the connecting pipe 25. At the same time, the spring 3 26 is compressed. When the sealing column 24 leaves the inner wall of the connecting pipe 25, the connecting pipe 25 is just abutted against one end of the water inlet pipe 20 to form a seal, thereby realizing the opening of the cooling water. When the hydraulic cylinder 4 moves up and resets, the connecting pipe 25, which loses the water pressure, is reset under the action of the spring 3 26 and re-sealed and inserted into the sealing column 24, automatically closing the water outlet. This design helps to save cooling water resources.

[0032] Among them, the bracket 2 is fixedly installed on the front side of the top of the workbench 1, the hydraulic cylinder 4 is installed on the top of the bracket 2, the motor 3 is installed on the bottom of the bracket 2, the sealing block 22 is located at the bottom of the inner wall of the sealing cylinder 7, and the bottom of the sealing block 22 abuts against and seals the cooling water in the inner cavity of the workbench 1.

[0033] The sealing cylinder 7 and the piston rod 6 are nested together, providing a guiding function for the up and down movement of the forging hammer 16. When the piston rod 6 does not move downward, the sealing block 22 is higher than the bottom of the inner wall of the sealing cylinder 7. When the piston rod 6 moves upward, the sealing block 22 is pulled upward by the second spring 23, and the water inlet mechanism 9 is opened to automatically add cooling water.

[0034] Among them, the forging hammer 16 is located at 0° in the inner ring surface of the worktable 1, the sealing column 24 is located at 120° in the inner cavity of the worktable 1, the sealing column 24 is coaxially distributed with the connecting cylinder 15, and the gear 13 meshes with the outer gear ring 8.

[0035] like Figure 7 As shown, the perimeter of the worktable 1 is represented by 0°, 120° and 240°, which helps to increase the understanding of the device's workflow. The motor 3 drives the mounting ring 11 and the forging die 12 to rotate clockwise, moving the workpiece to different areas for different processing operations.

[0036] The water inlet mechanism 9 includes a one-way plate 92 located in the inner cavity of the workbench 1, which is fixedly installed on the rear side of the top of the workbench 1. The outer surface of the water inlet pipe 91 is movably sleeved with a one-way plate 92 located in the inner cavity of the workbench 1. One end of the one-way plate 92 is elastically connected to the top of the inner cavity of the workbench 1, and the other end of the one-way plate 92 is elastically connected with a spring 93.

[0037] The water inlet mechanism 9 is connected to an external water tank. When the piston rod 6 moves downward and applies pressure to the inner cavity of the worktable 1, the spring 93 moves upward under the action of water pressure and blocks the water inlet pipe 91 to prevent cooling water from being discharged from here. When the piston rod 6 moves upward, it drives the sealing block 22 to move upward and allows the spring 93 to move downward, opening the water inlet pipe 91. At this time, the external water tank can replenish new cooling water to the water inlet pipe 91.

[0038] The inner ring surface of the workbench 1 is designed in a stepped manner, and the bottom of the forging die 12 abuts against the inner side of the top of the workbench 1.

[0039] like Figure 5 As shown, the inner ring surface of the workbench 1 is designed in a stepped manner, and its inner top abuts against the bottom of the forging mold 12. When the forging mold 12 is hit by the forging hammer 16, the workbench 1 can provide support to prevent the connecting frame 10 from being damaged.

[0040] There are eight sets of jet nozzles 17, and the axis of each set of jet nozzles 17 points to the axis of the forging die 12. The inclined plate 19 is designed to be inclined and is directly opposite to the axis of the jet nozzles 17.

[0041] The high-pressure water jet from the nozzle 17 directly drives the inclined plate 19 to rotate. At the same time, the impact causes the cooling water to splash, which increases its contact area with the air and the workpiece, thereby improving the cooling efficiency of the device.

[0042] When any set of forging dies 12 moves to the 120° position in the inner ring of the workbench 1, the water receiving pipe 20 that moves to this position coincides with the axis of the connecting pipe 25.

[0043] When the forging die 12 moves the water pipe 20 to a position of 120°, the rotating forging die 12 can align and coincide the axis of the water pipe 20 with the axis of the sealing column 24. Thus, when the connecting pipe 25 moves outward, it can abut against one end of the water pipe 20 to form a perfect seal.

[0044] Among them, a sealing ring 21 is fixedly sleeved on the outer surface of the water inlet pipe 20, and a sealing ring 27 is fixedly sleeved on the outer surface of the connecting pipe 25. Both the sealing ring 21 and the sealing ring 27 are made of rubber blocks.

[0045] When the connecting pipe 25 and the water inlet pipe 20 come into contact, the sealing ring 27 and the sealing ring 27 press against each other, thereby providing an external sealing function between the connecting pipe 25 and the water inlet pipe 20 to prevent cooling water leakage.

[0046] In the initial position, the connecting pipe 25 does not abut against one end of the sealing ring 21, and at this time the sealing post 24 is sealed and inserted into the inner wall of the connecting pipe 25.

[0047] When the connecting pipe 25 is in its initial position, it is located inside the connecting cylinder 15. At this time, the sealing column 24 is inserted into the inner wall of the connecting pipe 25 to form a seal and prevent water in the inner cavity of the workbench 1 from leaking along the connecting pipe 25.

[0048] Working principle:

[0049] When this device is in operation, the 240° position around the workbench 1 is set as the loading and unloading area, the 0° position is the forging area, and the 120° position is the cooling area. The red-hot workpiece is placed in the mold cavity of the forging mold 12.

[0050] Then, start motor 3 and drive connecting frame 10 and mounting ring 11 to rotate. Forging die 12 rotates by gear 13 and external gear ring 8 to adjust the position of workpiece and drive the three sets of forging dies 12 to rotate 120° clockwise. At this time, the workpiece is driven to the forging zone. Start hydraulic cylinder 4 and drive connecting plate 5, forging hammer 16 and sealing cylinder 7 to move downward. On the one hand, forging hammer 16 presses the workpiece downward and forges one end of the workpiece under the action of the mold cavity of forging die 12. On the other hand, piston column 6 is driven downward synchronously and compresses spring 23 to press sealing block 22 downward, so that the cooling water in the inner cavity of worktable 1 is filled in.

[0051] Then, the hydraulic cylinder 4 resets, and the motor 3 drives the connecting frame 10, mounting ring 11, and forging die 12 to continue rotating 120°. At this time, the forged workpiece moves to the cooling zone, while a new workpiece enters the forging zone. At this time, the axis of the sealing ring 21 in the cooling zone coincides with the sealing column 24. As the piston column 6 moves down again, the workpiece in the forging zone is forged. At the same time, as the piston column 6 compresses the space inside the worktable 1, the connecting pipe 25 moves towards the side closer to the water receiving pipe 20 under the action of water pressure and connects with the water receiving pipe 20. Pipe 20 abuts, and is sealed by sealing ring 21 and sealing ring 27. The connecting pipe 25 moves to make the sealing column 24 leave it. The worktable 1 and the water storage ring 14 are connected, and a large amount of cooling water can enter the water storage ring 14 and be sprayed outward through the spray nozzle 17. The high-pressure water flow hits the inclined plate 19, causing multiple sets of inclined plates 19 to drive the rotating ring 18 to rotate, generating axial wind force. The cooling water dispersed by the inclined plate 19 falls on the surface of the workpiece, making the workpiece cool down quickly. Combined with the airflow generated by the rotation of the inclined plate 19, the workpiece is effectively cooled.

[0052] Subsequently, the hydraulic cylinder 4 moves upward and resets, and the sealing block 22 and spring 23 reset. At this time, supplementary cooling water can be injected through the water inlet pipe 91, and the motor 3 continues to rotate 120° to move the workpiece to the loading and unloading area. The cooled workpiece is taken out, and then the red-hot workpiece to be forged is put in.
