Description

Technical Field

[0001] The present invention relates to the technical field of hot die forging, and in particular to a high-efficiency hot die forging device for manufacturing a transmission assembly of a gearbox. Background Art

[0002] As a key transmission component of the gearbox, the gear assembly of the gearbox is widely manufactured using hot die forging technology. This process can give the gear good internal structure and mechanical properties, effectively improving its reliability under complex working conditions. The hot die forging process needs to be implemented with the assistance of hot die forging equipment.

[0003] When using the existing hot die forging device, it is necessary to first forge and hammer flat the alloy raw material block, and then forge the initial forging formed by the hammering into a disc-shaped rough-machined forging that is convenient for subsequent processing of the gear, and finally forge the rough-machined forging into a precision gear to complete the manufacture of the gear. The transfer operation of the above-mentioned alloy raw material block and the rough-machined forging between the forging bearing component, the rough-machined die and the fine-machined mold is usually implemented by clamping with an external clamp that is separately provided with the device. Although the external separate clamp is more flexible to use, first, during the transfer process, it is necessary to use hand force to resist the gravity of the alloy raw material block or the rough-machined forging, and the operation is more laborious. Second, during the transfer process, it is necessary to first lift the alloy raw material block or the rough-machined forging upward to form a passage space between the two and the forging bearing component, the rough-machined die or the fine-machined mold to facilitate the smooth and unobstructed transfer of the two, and then translate the two horizontally. Such step-by-step operation is more troublesome and inconvenient. Summary of the Invention

[0011] Furthermore, a U-shaped handle frame is welded to the closed end of the U-shaped retaining frame, and the closed end of the U-shaped pull frame is slidably placed inside the U-shaped handle frame.

This can save the trouble of lifting the clamp to an empty position first during the clamping and transfer of the forging, so that the forging is in an unobstructed sliding state, and then horizontally moving the clamp to perform the sliding transfer of the forging. It eliminates the step of lifting the clamp to an empty position, is easy to operate, helps to improve the transfer efficiency of the forging and indirectly improves the forging processing efficiency of the forging.

[0018] 4. In the process of continuously sliding the U-shaped pull frame and compressing the force transmission spring, the compression force applied by the U-shaped pull frame to the force transmission spring through the transmission ring gradually increases. The gradually increasing compression is transmitted to the two clamping plates in turn through the sliding shaft and the U-shaped transmission frame, prompting the two clamping plates to clamp the forgings strongly and stably, which helps to ensure the clamping stability of the forgings by the fixture during the transfer of the forgings.

[0034] The following is a detailed explanation of the working principle, specific details, implementation steps, functions and interrelationships of the various features of the above embodiment, and the role played by these features in implementing the technical solution: The transmission assembly of the gearbox includes a transmission gear. The device is suitable for forging the transmission gear. When forging the transmission gear, the alloy raw material block 11 is first placed on the top of the circular supporting platform 401 using an external fixture. Then, the hand is waved above the photoelectric switch 10 to block and trigger the photoelectric switch 10. After the photoelectric switch 10 is triggered, the trigger signal is transmitted to the electrical control unit. When the electrical control unit receives the trigger signal, it starts the two forging cylinders 2 and controls the piston rods of the two forging cylinders 2 to slide down and extend. When the two piston rods slide down and extend, they drive the counterweight block 3 and the forging hammer column 301 to slide down, and perform preliminary processing on the alloy raw material block 11 by forging and flattening, so that the alloy raw material block 11 after preliminary processing can be forged into a rough-machined forging with a flat disc structure. After the piston rods of the two forging oil cylinders 2 slide down and extend to complete the preliminary processing of the alloy raw material block 11, they are automatically controlled by the electrical control unit to slide up and retract, and the forging hammer column 301 is controlled to separate from the preliminarily processed alloy raw material block 11. After the forging oil cylinder 2 shrinks and returns to its position, it stays in the retracted state. Then, the preliminarily processed alloy raw material block 11 is clamped and transferred to the rough processing die 402 through the clamp 7 and carried on the top of the top shaft 602 in the upward sliding ejection state (the top shaft 602 is the top shaft 602 on the rough processing die 402). Then, the hand is waved again to trigger the photoelectric switch 10. After the photoelectric switch 10 is triggered, the electrical control unit controls the piston rods of the two forging oil cylinders 2 to extend downward, and at the same time controls the piston rod of the ejection oil cylinder 6 to retract downward, wherein, the top When the piston rod of the oil cylinder 6 retracts, the driving top shaft 602 slides down and resets, and drops the preliminarily processed alloy raw material block 11 into the forming die cavity on the rough processing die 402. When the piston rods of the two forging oil cylinders 2 extend downward, they drive the forging hammer column 301 to slide down and forge the preliminarily processed alloy raw material block 11 into a rough processing forging, so that the transmission gear can be accurately processed later. After completing the processing of the rough processing forging, the piston rods of the two forging oil cylinders 2 automatically slide up and retract to separate from the rough processing forging and drive the sliding assembly 302 to slide up and reset. When the sliding assembly 302 slides up and resets, it moves away from the photoelectric switch 10, releases the blocking trigger of the photoelectric switch 10, and restores the photoelectric switch 10 to the untriggered state. When the photoelectric switch 10 returns to the untriggered state, it will be restored. The reset signal is transmitted to the electrical control unit. When the electrical control unit receives the recovery signal, it controls the piston rod of the ejection cylinder 6 to slide upward and extend, and drives the horizontal synchronous plate 601 and the ejector shaft 602 to slide upward, ejecting the rough-machined forging from the forming cavity of the rough-machined die 402 (Note: After the forging cylinder 2 drives the forging hammer column 301 to slide and separate from the rough-machined forging, the sliding assembly 302 slides away to a height that restores the photoelectric switch 10 to the untriggered state). After the piston rod of the ejection cylinder 6 slides upward and extends, it stops and remains in the extended state. Thereafter, the ejected rough-machined forging is transferred to the finishing die 403 by the clamp 7 and carried on the top of the ejector shaft 602 in the upward sliding and ejecting state (the ejector shaft 602 is the ejector shaft 602 on the finishing die 403).Then, the hand is waved again to trigger the photoelectric switch 10. After the photoelectric switch 10 is triggered, the electrical control unit controls the forging cylinder 2 and the ejection cylinder 6 to repeat the above actions, performing precise forging on the rough forging to complete the manufacturing of the transmission gear, and ejecting the formed transmission gear. Finally, the ejected transmission gear is transferred to the unloading station on the rectangular mounting seat 4 near the finishing die 403 by the clamp 7, and the transmission gear is loosened and dropped to unload. At this point, the first forging and forming of the transmission gear is completed. The above process can be repeated to carry out continuous processing and manufacturing of the transmission gear.

[0035] The photoelectric switch 10 and the electrical control unit together constitute an intelligent control system for controlling the ejection cylinder 6 to automatically extend and automatically eject the forging (the forging includes the alloy raw material block 11 after preliminary processing, the rough-processed forging, and the formed transmission gear). This system can save the trouble of manually operating the ejection cylinder 6 multiple times to eject the forging during the forging process, and is easy to operate and use.

[0036] The two splints 701, the two connecting rods 708 and the U-shaped transmission frame 702 are connected together to form a crank rocker mechanism. Through this mechanism, the U-shaped transmission frame 702 can be slid toward or away from the U-shaped handle frame 704, which can drive the two splints 701 to swing relative to each other and tighten or loosen the forging; the U-shaped transmission frame 702 can be driven to slide in the above manner through the sliding shaft 705; the U-shaped transmission frame 702 can slide along the rotating shaft 7011 in the above manner through two sliding grooves 7021.

[0037] The elastic force of the return spring 7052 is less than the elastic force of the force transmission spring 7053. The hand can pull the transmission ring 7061 toward the U-shaped handle frame 704 through the U-shaped pull frame 706. When the transmission ring 7061 is driven to slide in this direction, the power transmission of the force transmission spring 7053 and the retaining ring 7051 can compress the return spring 7052, and push and drive the sliding shaft 705 and the U-shaped transmission frame 702 to slide toward the U-shaped handle frame 704, controlling the two splints 701 to swing toward each other and clamp; when the forging is transferred to place, the U-shaped pull frame 706 is released. After the U-shaped pull frame 706 is released, the return spring 7052 loses the compression holding force indirectly from the U-shaped pull frame 706, and can automatically push back to drive the retaining ring 7051 and the U-shaped transmission frame 702 to slide away from the U-shaped handle frame 704, controlling the two splints 701 to swing back and loosen, thereby releasing the clamping state.

[0038] The pulling, sliding and releasing operations of the U-shaped pull frame 706 can be driven by the free fingers of the hand holding the U-shaped handle frame 704.

[0039] The clamp 7 transfers the forging by sliding the U-shaped slide frame 707 along the two track grooves 501. This allows the gravity of the forging to be offset by the support of the track plate 5 during the transfer process, eliminating the need for workers to exert additional manual effort to counteract the gravity, and making the operation more labor-saving. The rectangular limit frame 8 slides in conjunction with the U-shaped slide frame 707 to implement swing limit on the U-shaped slide frame 707 and the clamp 7, thereby preventing the clamp 7 from swinging and shifting when sliding the forging, thereby affecting the stability of the sliding transfer operation.

[0040] When the U-shaped pull frame 706 is driven to slide toward the U-shaped handle frame 704 and the two clamps 701 are driven to swing and clamp against the forging, the U-shaped transmission frame 702 and the sliding shaft 705 stop sliding under the abutment limit of the forging. When the sliding shaft 705 is stopped, the U-shaped pull frame 706 is pulled and slid toward the U-shaped handle frame 704. When the U-shaped pull frame 706 is continued to be pulled and driven, it begins to compress and transmit force through the transmission ring 7061. The spring 7053 drives the two L-shaped driving plates 7062 to contact the inclined surfaces of the two triangular force blocks 802. When the L-shaped driving plates 7062 contact the inclined surfaces of the triangular force blocks 802, the two L-shaped driving plates 7062, the U-shaped pull frame 706 and the clamp 7 as a whole can be pushed and driven to slide upward through the guiding principle of the inclined surfaces of the two triangular force blocks 802, thereby lifting the forging clamped on the clamp 7 upward so that the forging is aligned with the clamp 7. The circular supporting platform 401 and the rough processing die 402 are separated, and an interval space is left between the forging and the circular supporting platform 401 and the rough processing die 402 for the clamp 7 to implement an obstacle-free sliding transfer of the forging; in this way, through the guiding principle of the inclined surfaces of the two triangular force blocks 802, the upward sliding operation of the clamp 7 can be indirectly driven by the driving force of the clamp 7 controlled by the sliding U-shaped pull frame 706, which makes the clamping operation and the upward sliding operation of the clamp 7 possible to be implemented by a one-time pulling and driving of the U-shaped pull frame 706, and can save the trouble of first lifting the clamp 7 to an empty position during the process of clamping and transferring the forging, so that the forging is in an obstacle-free sliding state, and then the clamp 7 can be translated to implement the sliding transfer of the forging, eliminating the step of lifting the clamp 7 to an empty position, and is easy to operate and use, which helps to improve the transfer efficiency of the forging and indirectly improve the forging processing efficiency of the forging.

[0041] In the process of continuously sliding the U-shaped pull frame 706 and compressing the force transmission spring 7053, the compression force applied by the U-shaped pull frame 706 to the force transmission spring 7053 through the transmission ring 7061 gradually increases, and the gradually increasing compression is transmitted to the two clamps 701 in turn through the sliding shaft 705 and the U-shaped transmission frame 702, prompting the two clamps 701 to clamp the forging strongly and stably, which helps to ensure the clamping stability of the forging by the clamp 7 during the transfer of the forging.

[0042] When the forging is transferred into place and the U-shaped pull frame 706 is released, the force transmission spring 7053, which is continuously compressed by the sliding of the U-shaped pull frame 706, loses the compression holding force from the U-shaped pull frame 706, and can automatically push back to drive the transmission ring 7061 and the U-shaped pull frame 706 to slide back and reset, and control the L-shaped drive plate 7062 to slide and separate from the triangular force block 802, so that the clamp 7 relies on gravity to slide down and reset to release the upward sliding space of the forging.

[0043] It is worth noting that when the U-shaped pull frame 706 in a continuously sliding state compresses the force transmission spring 7053 to the limit state, the L-shaped driving plate 7062 still remains in the use state of abutting against the inclined surface of the triangular force block 802 and does not separate from the triangular force block 802.

[0044] It is worth noting that the composition of the electrical control unit, the selection of the models of the photoelectric switch 10 and the solenoid valve, and the connection and wiring method between the photoelectric switch 10 and the solenoid valve and the electrical control unit are existing technologies for technicians in this field engaged in the electrification and intelligent transformation of equipment, so they will not be described in detail here.
