Description

Technical Field

[0001] The invention belongs to the technical field of hot die forging presses, and in particular relates to a lightweight aluminum alloy hot die forging press. Background Art

[0002] Hot die forging presses can produce high-strength aluminum alloy forgings in a relatively short period of time through forging processing at high temperatures. This equipment uses dies to accurately shape aluminum alloy materials, ensuring the shape and dimensional accuracy of the forgings. Using aluminum alloy forgings to replace some steel parts can effectively improve the performance of parts, ensure the quality of parts, and extend the service life of parts.

[0003] Publication No.: CN119319199A, discloses: a lightweight aluminum alloy hot die forging press for automobiles, which can drive the arc-shaped support seat to rotate during the rising process of the forging block by setting a transmission component, a connecting rod and an arc-shaped support seat. During the rotation process, the arc-shaped support seat can drive the lower die to tilt, and at the same time, the guide column and the guide slide groove squeeze each other. At a certain inclination angle, the unloading push plate is driven to completely push out the formed workpiece, so as to achieve the purpose of demolding the formed workpiece and avoid problems such as workpiece residue or die jamming. The rack 2 at the bottom end of the arc-shaped support seat is meshed with the rack 1 of the unloading module. When the arc-shaped support seat is rotated to the demolding angle, the unloading guide plate and the lower die are fitted together to collect the pushed-out molded parts, which is convenient for subsequent processing and achieves the purpose of demolding and unloading.

[0004] The above-mentioned prior art still has the following disadvantages in the specific implementation process:

[0005] It can only realize demoulding and unloading of the workpiece after forging, but it is not convenient to place the unforged and high-temperature workpiece into the forging position, and it is only applicable to the workpiece formed by a single forging, and the scope of application is relatively limited. When the workpiece needs to be forged multiple times, the forging block needs to move up and down repeatedly. At the same time, in the process of the forging block rising and falling, it will drive the transmission assembly to rise and fall synchronously. Two telescopic cylinders are required to cooperate with the lifting and lowering of the forging block for contraction, which has certain difficulties in actual application, and two telescopic cylinders are set as the driving mechanism, which increases the use cost of the device. If one of the telescopic cylinders fails, the demoulding and unloading functions cannot be realized, and the forging operation of the workpiece is affected, and the use effect is not good.

[0041] The linkage assembly includes a second gear 27 and a first gear 29. A rotating rod 5 is fixed to both the front and rear sides of the movable block 3. The second gear 27 is arranged on the rotating rod 5, and the second gear 27 is arranged on the upper side of the rack 18. The second gear 27 is meshed with the rack 18. A fixed block 33 is fixed to the front side of the top of the press base 1. The front and rear rotating rods 5 respectively penetrate the fixed block 33 and the fixed frame 2, and the front and rear rotating rods 5 are respectively rotatably connected with the fixed block 33 and the fixed frame 2.

[0042] In the above structure, the pulley 30 and the transmission belt 31 cooperate with each other, so as to drive the rotating shaft 28 and the support shaft 7 to rotate synchronously. The rotating shaft 28 drives the first gear 29 to rotate. Under the meshing action of the first gear 29 and the second gear 27, the second gear 27 on the rear side is driven to rotate.

[0045] Example:

[0046] During use, a conveyor is provided on the left side of the temporary storage box 24, which is convenient for intermittently conveying the high-temperature workpiece to the loading plate 25 in the temporary storage box 24. When the workpiece is forged, the servo motor 35 is first started, and the servo motor 35 drives the rotating shaft 28 to rotate. Under the action of the pulley 30 and the transmission belt 31, the support shaft 7 is driven to rotate synchronously;

[0047] The first gear 29 is driven to rotate by the rotating shaft 28. Under the meshing action of the first gear 29 and the second gear 27, the second gear 27 is driven to rotate. Combined with the rotation installation of the rotating rod 5, the movable block 3 and the second gear 27 on the front side are driven to rotate. At the same time, under the meshing action of the second gear 27 and the rack 18, and the sliding cooperation between the T-shaped block 17 and the T-shaped groove, the rack 18 is driven to slide stably to the right;

[0048] When the rack 18 slides to the right, the disk 22 and the connecting rod 23 drive the temporary storage box 24 to move toward the press base 1. At the same time, when the movable block 3 rotates around the rotating rod 5, the lower die 4 is driven to tilt toward the temporary storage box 24 until the discharge port of the temporary storage box 24 moves to the upper side of the lower die 4. At this time, the lower die 4 is in a slightly tilted state.

[0049] At this time, the servo motor 35 stops running and starts the hydraulic rod 26. Under the hinged action at both ends of the hydraulic rod 26, combined with the hinged installation of the loading plate 25, the loading plate 25 is driven to flip, and combined with the inclined structure on the right side of the temporary storage box 24, the workpiece on the loading plate 25 slides onto the lower die 4, realizing the loading operation of the workpiece, solving the problem that the prior art can only realize demoulding and unloading of the forged workpiece, but is not convenient for placing the unforged high-temperature workpiece into the forging position;

[0050] In the initial state, there is a certain gap between the lower side of the push plate 10 and the bottom of the inner cavity of the lower mold 4, so that when the temporary storage box 24 is adjusted close to the lower mold 4, the support shaft 7 rotates synchronously and drives the winding roller 8 to wind up the steel rope 9;

[0051] After the workpiece slides onto the lower die 4, the servo motor 35 is driven to rotate in the opposite direction, driving the rack 18 to move to the left until the lower die 4 returns to its initial state. At this time, the lower die 4 is located directly below the upper die 37. When the workpiece is forged, the hydraulic cylinder 38 is started to drive the forging block 36 to move downward, thereby driving the upper die 37 to move toward the lower die 4, and forging the workpiece on the lower die 4;

[0052] The sliding cooperation between the guide block and the guide rod effectively limits and guides the forging block 36, thereby ensuring the stability of the forging block 36 and the upper die 37 in the up and down movement process during the forging process.

[0053] After the forging of the workpiece is completed, the servo motor 35 continues to operate, driving the rack 18 to continue to move to the left, and under the action of the universal wheel 21, the collection box 19 is driven to move toward the press base 1, and at the same time, under the action of the movable block 3, the lower die 4 is driven to flip toward the collection box 19;

[0054] During this process, the driving belt 31 and the pulley 30 cooperate with each other, driving the support shaft 7 to rotate synchronously, thereby driving the winding roller 8 to release the steel rope 9. At this time, the downward pulling force of the steel rope 9 on the push plate 10 is released. Under the elastic action of the spring 14, combined with the telescopic rod 13 and the fixed plate 12, the piston rod 11 is pushed upward, and then the push plate 10 is squeezed toward the outside of the lower mold 4. The workpiece formed in the lower mold 4 is ejected outward by the push plate 10, thereby achieving the purpose of demolding the workpiece;

[0055] The flipping of the lower die 4 is synchronized with the movement of the collecting box 19. When the lower die 4 is flipped and tilted to a certain angle, the open end of the collecting box 19 cooperates with the right side of the lower die 4. At this time, the demolded workpiece slides to the right into the collecting box 19 under the action of the tilt of the lower die 4, thereby realizing the unloading and collection of the formed workpiece. This solves the problem that the prior art is only applicable to workpieces formed by a single forging process and has a relatively limited scope of application. When the workpiece needs to be forged multiple times, the forging block 36 needs to move up and down repeatedly. At the same time, during the rising and falling process of the forging block 36, the transmission assembly will be driven to rise and fall synchronously. Two telescopic cylinders are required to cooperate with the lifting and lowering of the forging block 36 for contraction. There are certain difficulties in actual application, and two telescopic cylinders are set as the driving mechanism, which increases the use cost of the device. At the same time, it solves the problem that if one of the telescopic cylinders in the prior art fails, the demolding and unloading functions cannot be realized, which affects the forging operation of the workpiece and has a poor use effect.

[0056] It should be further explained that the installation structure, connection method or setting method of each component in the present invention are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects. At the same time, the hydraulic rod 26, servo motor 35 and hydraulic cylinder 38 in the present invention are all purchased on the market, and technical personnel in this field can install and use them as required.
