Description

Technical Field

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

[0002] Gears, as one of the most basic components for transmitting motion and power, are widely used in industry due to their advantages such as high meshing efficiency, low noise, and large transmission load. Gear composite forging requires first hammer forging the forging blank, followed by die forging using specialized dies. In gear manufacturing, in addition to conventional steel, high-quality aluminum, high-quality magnesium, and high-quality titanium are also required for forging in fields such as aerospace.

[0003] Generally, in gear composite forging, the movement, blanking, and positioning of the forging billet all rely on manual labor, and special tools are required. The forging billet itself is often quite heavy, which makes it not only laborious to move the forging billet manually, but also limits the processing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a gear composite forging equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A gear composite forging forming device includes a base, a control console fixedly connected to the base, and a hydraulic cylinder fixedly connected to the base. It also includes: A composite forging structure connected to a base includes a forging table fixedly installed on the base. A through slot is provided in the middle of the forging table. A blank placement slot is provided on the forging table. A lower die body is assembled on the forging table. An arc-shaped linkage frame is fixedly connected to the moving end of the hydraulic cylinder. An upper die body and a forging hammer are respectively assembled at the two lower ends of the arc-shaped linkage frame. The upper die body is located above the lower die body, and the forging hammer is located above the blank placement slot. A three-position movable structure is installed on the base. The three-position movable structure includes a movable linkage mechanism connected to the base. The movable linkage mechanism is connected to a centering and angle-changing clamping mechanism. The three-position movable structure is used to drive the centering and angle-changing clamping mechanism to move between the three stations: the forging billet placement slot 7, the upper part of the through slot, and the lower mold body.

[0006] As a further improvement of the present invention: the moving linkage mechanism includes a bridge-shaped frame fixedly connected to the base, the bridge-shaped frame having a bridge-shaped through groove, a rectangular slot block being slidably connected to the bridge-shaped through groove, a bent arm being fixedly connected to one end of the rectangular slot block facing the centering angle clamping mechanism, the bent arm being fixedly connected to the centering angle clamping mechanism, a protruding shaft being fixedly installed at one end of the rectangular slot block away from the centering angle clamping mechanism, a first motor being fixedly connected to the base, a swing arm being fixedly connected to the output shaft of the first motor, and a straight groove being slidably connected to the protruding shaft on the swing arm.

[0007] As a further improvement of the present invention: the centering angle clamping mechanism includes a central frame fixedly connected to the curved arm, a set of electric telescopic rods fixedly installed in the middle of the central frame, a cross slidably connected to the moving end of the electric telescopic rods, extension frames slidably connected to the four ends of the cross, a hinge plate hinged to the extension frame, a swing frame hinged to the hinge plate, a strip hinge seat slidably connected to the central frame, a driven telescopic frame fixedly connected to the strip hinge seat, a driven telescopic frame fixedly connected to the end of the driven telescopic frame away from the strip hinge seat, a clamping claw assembled on the swing frame, a second motor fixedly installed in the middle of the central frame, a four-slotted plate fixedly connected to the output shaft of the second motor, four sets of inclined slots equally spaced along the circumference of the four-slotted plate, the four sets of inclined slots arranged around the central axis of the four-slotted plate, each set of inclined slots slidably connected to the axial protruding end of a set of strip hinge seats.

[0008] As a further improvement of the present invention: the central frame is coaxially fixedly connected to a ring body, and the four slotted discs are fixedly connected to four sets of support plates, each set of support plates being slidably connected to the ring body.

[0009] As a further improvement of the present invention: a collection box is provided below the through groove, the collection box is fixedly connected to the base, an inclined guide surface is provided at the bottom of the inner cavity of the collection box, the inclined guide surface is provided below the through groove, and a material dispensing port is provided on the collection box.

[0010] As a further improvement of the present invention: two sets of sliding rods are fixedly installed on the top of the bow-shaped linkage frame. The sliding rods are slidably connected to the base, and the axial extension direction of the two sets of sliding rods is parallel to the extension and retraction direction of the hydraulic cylinder.

[0011] As a further improvement of the present invention: the bow-shaped linkage frame has a honeycomb structure inside.

[0012] Compared with the prior art, the beneficial effects of the present invention are: In use, the forging blank to be processed is placed in the forging blank placement slot. The centering and angle-changing clamping mechanism centers and clamps the forging blank. Then, the centering and angle-changing clamping mechanism releases the forging blank. Subsequently, the moving linkage mechanism drives the centering and angle-changing clamping mechanism to move, so that the centering and angle-changing clamping mechanism moves above the through slot, providing space for the forging hammer to approach the forging blank. The hydraulic cylinder extends and retracts, driving the bow-shaped linkage frame to move back and forth. The forging hammer strikes the forging blank to perform preliminary forging. Then, the hydraulic cylinder retracts, driving the bow-shaped linkage frame to move upward. The moving linkage mechanism drives the centering and angle-changing clamping mechanism to move, centering and angle-changing. A variable-angle clamping mechanism holds the forging blank. A moving linkage mechanism drives the variable-angle clamping mechanism to move downwards into the lower die body, placing the forging blank into the lower die body. The moving linkage mechanism then drives the variable-angle clamping mechanism to move above the through slot. As the hydraulic cylinder extends, the upper and lower die bodies close, completing the forging process of the forging blank. After forming, the hydraulic cylinder retracts and resets. The moving linkage mechanism then drives the variable-angle clamping mechanism to move the formed forging blank back above the through slot. Finally, the variable-angle clamping mechanism releases the formed forging blank, allowing it to fall into the through slot. This invention utilizes a composite forging structure combined with a three-position moving structure to perform composite forging processing on the forging blank, automating the movement, positioning, and unloading of the forging blank, saving manpower and improving processing efficiency.

[0024] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0025] Example 1, see Figures 1-10 As shown, a gear composite forging forming equipment includes a base 1, a control console 2 fixedly connected to the base 1, a hydraulic cylinder 3 fixedly connected to the base 1, and further includes: A composite forging structure 4 connected to the base 1 includes a forging table 5 fixedly installed on the base 1. The forging table 5 has a through groove 6 in the middle and a blank placement groove 7. A lower die body 8 is assembled on the forging table 5. The connection between the forging table 5 and the lower die body 8 can be selected as a bolt connection or a quick-release structure connection. The moving end of the hydraulic cylinder 3 is fixedly connected to an arc-shaped linkage frame 9. An upper die body 10 and a forging hammer 11 are respectively assembled at the lower two ends of the arc-shaped linkage frame 9. The upper die body 10 is located above the lower die body 8, and the forging hammer 11 is located above the blank placement groove 7. A three-position movable structure 12 is installed on the base 1. The three-position movable structure 12 includes a movable linkage mechanism 13 connected to the base 1. The movable linkage mechanism 13 is connected to a centering and variable angle clamping mechanism 14. The three-position movable structure 12 is used to drive the centering and variable angle clamping mechanism 14 to move between the three stations: above the forging blank placement groove 7, the through groove 6, and the lower mold body 8.

[0026] In use, the forging blank to be processed is placed in the forging blank placement slot 7. The centering and angle-changing clamping mechanism 14 centers and clamps the forging blank. Then, the centering and angle-changing clamping mechanism 14 releases the forging blank. Subsequently, the moving linkage mechanism 13 drives the centering and angle-changing clamping mechanism 14 to move, so that the centering and angle-changing clamping mechanism 14 moves above the through slot 6, providing space for the forging hammer 11 to approach the forging blank. The hydraulic cylinder 3 extends and retracts, driving the bow-shaped linkage frame 9 to reciprocate. The forging hammer 11 hammers the forging blank to perform preliminary forging. Then, the hydraulic cylinder 3 retracts, driving the bow-shaped linkage frame 9 to move upward. The moving linkage mechanism 13 drives the centering and angle-changing clamping mechanism 14 to move, centering and changing the angle. Angle clamping mechanism 14 clamps the forging blank. Motion linkage mechanism 13 drives the centering angle clamping mechanism 14 to move downwards to the lower die body 8, placing the forging blank into the lower die body 8. Motion linkage mechanism 13 then drives the centering angle clamping mechanism 14 to move above the through groove 6. As the hydraulic cylinder 3 extends, the upper die body 10 and lower die body 8 close, completing the forging process. After forming, the hydraulic cylinder 3 retracts and resets. Motion linkage mechanism 13 drives the centering angle clamping mechanism 14 to move the formed forging blank back above the through groove 6. Then, the centering angle clamping mechanism 14 releases the formed forging blank, causing it to fall into the through groove 6. This invention uses a composite forging structure 4 in conjunction with a three-position moving structure 12 to perform composite forging processing on the forging blank, automating the movement, positioning, and unloading of the forging blank, saving manpower and improving processing efficiency.

[0027] In one embodiment, the moving linkage mechanism 13 includes a bridge-shaped frame 15 fixedly connected to the base 1. The bridge-shaped frame 15 has a bridge-shaped through groove 16. A rectangular slot block 17 is slidably connected to the bridge-shaped through groove 16. A bent arm 18 is fixedly connected to one end of the rectangular slot block 17 facing the centering angle clamping mechanism 14. The bent arm 18 is fixedly connected to the centering angle clamping mechanism 14. A protruding shaft 19 is fixedly installed at one end of the rectangular slot block 17 away from the centering angle clamping mechanism 14. A first motor 20 is fixedly connected to the base 1. The first motor 20 is a servo motor. A swing arm 21 is fixedly connected to the output shaft of the first motor 20. A straight groove 22 is slidably connected to the protruding shaft 19 on the swing arm 21. When the mobile linkage mechanism 13 is working, the first motor 20 reciprocates and drives the swing arm 21 to rotate. The swing arm 21 moves the protruding shaft 19 through the straight groove 22, so that the rectangular groove block 17 slides back and forth along the bridge-shaped through groove 16, thereby completing the position drive and transfer of the centering angle clamping mechanism 14.

[0028] In one embodiment, the centering angle clamping mechanism 14 includes a central frame 23 fixedly connected to the curved arm 18. A set of electric telescopic rods 24 are fixedly installed in the middle of the central frame 23. The moving end of the electric telescopic rods 24 is fixedly connected to a cross 25 slidably connected to the central frame 23. The four ends of the cross 25 are slidably connected to extension frames 40. The extension frames 40 are hinged to hinge plates 26. The hinge plates 26 are hinged to swing frames 27. The swing frames 27 are hinged to strip-shaped hinge seats 28 slidably connected to the central frame 23. The strip-shaped hinge seats 28 are fixedly connected to driven telescopic frames 39. One end of the telescopic frame 39 away from the strip hinge seat 28 is fixedly connected to the extension frame 40. The swing frame 27 is equipped with a clamping claw 29. The center frame 23 is fixedly installed with a second motor 30. The output shaft of the second motor 30 is fixedly connected to a four-slot plate 31. The extension directions of the four sets of strip hinge seats 28 are all staggered at the same point, and this point is located on the rotation axis of the four-slot plate 31. The four-slot plate 31 is provided with four sets of inclined grooves 32 at equal angles along the circumference. The four sets of inclined grooves 32 are arranged around the central axis of the four-slot plate 31. Each set of inclined grooves 32 is slidably connected to the axial protruding end of a set of strip hinge seats 28. If the second motor 30 drives the four-slotted disk 31 to rotate, the four-slotted disk 31 pushes the strip-shaped hinge seat 28 to move radially synchronously through the inclined slot 32. Simultaneously, the strip-shaped hinge seat 28 slides relative to the center frame 23, driving the extension frame 40 to move via the driven telescopic frame 39. The extension frame 40 slides relative to the cross 25. The strip-shaped hinge seat 28 and the extension frame 40 respectively drive the swing frame 27 and the hinge plate 26 to move radially, so that they can move synchronously inward or outward without rotating the four sets of clamping claws 29, completing the centering and clamping of forging blanks of different sizes. Adjustment is required when needed. When the angle of the variable angle clamping mechanism 14 is adjusted, the electric telescopic rod 24 extends and retracts, driving the cross 25 to move. The cross 25 pulls the hinge plate 26 through the extension frame 40, and the hinge plate 26 pulls the swing frame 27 to rotate. The swing frame 27 drives the clamping claw 29 to rotate, thereby adjusting the clamping angle of the clamping claw 29 and completing the adaptive adjustment of the angle of the forging. This also facilitates the clamping operation of the variable angle clamping mechanism 14 on the bevel gear forging. During this process, as the distance between the extension frame 40 and the strip hinge seat 28 changes, the extension length of the driven telescopic frame 39 changes.

[0029] In one embodiment, the central frame 23 is coaxially fixedly connected to a ring 33, and the four-groove disk 31 is fixedly connected to four sets of support plates 34, each set of support plates 34 being slidably connected to the ring 33. When the four-groove disk 31 rotates, the support plates 34 slide along the ring 33, and the ring 33 provides guidance and support for the support plates 34, preventing the four-groove disk 31 from swaying and shaking when under force.

[0030] In one embodiment, a collection box 35 is provided below the through groove 6, and the collection box 35 is fixedly connected to the base 1. An inclined guide surface 36 is provided at the bottom of the inner cavity of the collection box 35, and the inclined guide surface 36 is located below the through groove 6. A material dispensing port 37 is provided on the collection box 35. A torsion spring 41 is fixedly installed inside the collection box 35, and a buffer plate 42 is rotatably installed inside the collection box 35 and fixedly connected to the torsion spring 41. The buffer plate 42 is located below the through groove 6. A limiting post 43 is fixedly connected to the inner wall of the collection box 35, and the limiting post 43 is located below the buffer plate 42. After the forged billet has been processed, it falls onto the buffer plate 42 after passing through the through groove 6. During this process, the buffer plate 42 rotates and impacts the inclined guide surface 36. As the forged billet slides off the buffer plate 42 and falls onto the inclined guide surface 36, the buffer plate 42 resets under the drive of the torsion spring 41, and the forged billet slides along the inclined guide surface 36 to the material dispensing port 37, facilitating the operator to remove the processed forged billet.

[0031] In one embodiment, two sets of slide rods 38 are fixedly installed on the top of the bow-shaped linkage frame 9. The slide rods 38 are slidably connected to the base 1, and the axial extension directions of the two sets of slide rods 38 are parallel to the extension and retraction directions of the hydraulic cylinder 3. The slide rods 38 guide the movement of the bow-shaped linkage frame 9, improve the stability of the movement of the bow-shaped linkage frame 9, and prevent the bow-shaped linkage frame 9 from tilting.

[0032] Example 2, based on Example 1, see [link / reference] Figure 1 and Figure 2 The bow-shaped linkage frame 9 has a honeycomb structure inside. By setting the internal structure of the bow-shaped linkage frame 9 to a honeycomb structure, the weight of the bow-shaped linkage frame 9 is reduced while ensuring its structural strength, thereby reducing the load on the hydraulic cylinder 3 and improving the operational stability of the equipment.

[0033] 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.
