Description

Technical Field

[0001] The invention belongs to the technical field of die forging, and specifically relates to a die forging device and a forging process specially used for large die forging. Background Art

[0002] In the die forging process, the metal blank needs to be placed in the cavity of the die first. Then, pressure is applied to the die through the forging equipment, so that the metal blank undergoes plastic deformation under the constraint of the die, fills the cavity of the die and gradually forms the desired forging shape. Finally, when the metal blank is completely deformed and reaches the desired size and shape, the forging is removed from the die.

[0003] The prior art also proposes some solutions: for example, a patent application with publication number CN117399548A discloses a forging device for high-quality mold steel. When the forging module moves downward, the main connecting rod drives the transmission mechanism to operate, so that the V-shaped bracket drives the transmission belt to slide along the Z-shaped sinking groove track and move out from the inside of the transmission groove, so as to avoid the mold steel plate being compressed and causing damage to the transmission belt, thereby improving the service life of the transmission belt; when the forging module moves downward for forging, the connecting rod drives the supporting mechanism to operate, so that the T-shaped pad moves up along the L-shaped adjustment groove track and flips ninety degrees before inserting into the inside of the transmission groove. At this time, the T-shaped pad is flush with the top surface of the support plate to support the mold steel plate, so as to avoid the formation of indentations on the surface of the mold steel plate during the forging process.

[0004] In the existing device, a large amount of forging slag will appear during the die forging process, and the slag will remain on the forging table. When there is a large amount of slag on the forging table, when the die is turned over or a new die is forged, the remaining slag will adhere to the bottom surface of the forging die. After the slag adheres, the shape and size of the bottom surface of the die will be changed during the forging process, resulting in a decrease in the die accuracy. The slag will also be embedded in the die surface to form bumps or pits, affecting the surface quality of the forged part.

[0005] To this end, the present invention provides a special die forging equipment and a forging process for large-scale die forging. Summary of the invention

[0028] The beneficial effects of the present invention are as follows:

[0029] 1. The forging equipment and forging process for a special die forging for large die forging described in the present invention can drive a cleaning component to work during the process of the die leaving the top of the forging table for flipping or cooling and taking out after each forging. The cleaning component can quickly and correctly sweep out the slag remaining on the top of the forging table. The rapid removal of the slag helps to maintain the continuity and stability of the forging operation, avoids residual slag from adhering to the bottom surface of the forging die, causing the slag to be embedded in the die surface to form bumps or pits, which helps to keep the die in good condition and ensure the size and shape accuracy of the forged parts.

[0044] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0045] like Figures 1 to 10As shown, the present invention provides a technical solution: a large-scale die forging special die forging device, comprising a workbench 1, a cooling table 2 and a forging table 3 are fixedly installed above the workbench 1, a fixed frame 36 is fixedly installed on the top of the workbench 1, a telescopic cylinder 37 is fixedly installed above the fixed frame 36, a forging part 38 is fixedly connected to the output end of the telescopic cylinder 37, and the forging part 38 is located directly above the forging table 3, an inner slide 4 is symmetrically fixedly installed on the top of the workbench 1, and an electric slider 5 is slidably connected to the inside of the two inner slides 4, and a clamping assembly is arranged on one side of the two electric sliders 5, and the clamping assembly is used to clamp the die during the forging process, a cleaning assembly for sweeping slag above the forging table 3 is arranged on one side above the forging table 3, and a flipping assembly is arranged on one side of the two inner slides 4, and the flipping assembly can drive the die to flip, and a collecting box 39 is arranged on the outer wall of the forging table 3.

[0046] During operation: before forging the mold, first place the mold to be forged in the center above the forging table 3, and clamp the outer wall of the mold through the clamping assembly. The mold clamping can ensure that the mold works stably during the forging process, avoid shaking or sliding, and ensure the shape and size accuracy of the forged part. Then start the telescopic cylinder 37, and its output end will drive the forging part 38 to continuously rise and fall to form an impact force to forge the top surface of the mold. When one side of the forging is completed, control the electric slider 5 and the clamping assembly to slide from one end inside the inner slide seat 4 to the other end. During the sliding process, the clamping assembly can drive the mold to slide. When the mold leaves the top of the forging table 3 and continues to slide, the electric slider 5 will first touch the cleaning assembly. The cleaning assembly can clean the slag generated above the forging table 3 just after forging. The cleaned slag will fall into the collection box 39 for collection, and it will also touch the flip assembly during the sliding process of the mold. The flipping assembly will flip the mold by driving the clamping assembly to flip. After flipping, the top and bottom surfaces of the mold are exchanged. At this time, the electric slider 5 is controlled to slide inside the inner slide seat 4 to drive the mold to return to its original position. The mold returns to the top of the forging table 3, and then the other side is forged. The forging is repeated in this way. After the last forging is completed, the mold is slid to the top of the cooling table 2 for cooling and shaping before being taken out. During the process of the mold leaving the top of the forging table 3 for flipping or cooling and taking out after each forging, the cleaning assembly can be driven to work. The cleaning assembly can quickly and correctly sweep out the slag remaining on the forging table 3. The rapid removal of slag helps to maintain the continuity and stability of the forging operation, avoid residual slag adhering to the bottom surface of the forging mold, causing the slag to embed into the mold surface, forming bumps or pits, which helps to maintain the integrity of the mold and ensure the size and shape accuracy of the forged part.

[0047] like Figure 4 and Figure 7As shown, the cleaning assembly includes a swing rod 11, the bottom of the swing rod 11 is rotatably connected to the top of the workbench 1, the outer wall of the swing rod 11 is fixedly connected to a gear 12, the top outer wall of the swing rod 11 is fixedly connected to a scraper 18, the bottom of the scraper 18 is flush with the top of the forging table 3, the teeth of the gear 12 are meshed with an arcuate toothed belt 13, and a pushing assembly is arranged under one of the electric sliders 5, and the pushing assembly is used to drive the teeth of the arcuate toothed belt 13 to mesh with the teeth of the gear 12.

[0048] During operation: after forging is completed, slag will remain on the top surface of the forging table 3. When the electric slider 5 slides inside the inner slide seat 4 to make the mold leave the top of the forging table 3 for flipping or cooling, the pushing component will push the outer wall of the arc toothed belt 13, so that the arc toothed belt 13 and the gear 12 will be meshed. After the arc toothed belt 13 is pushed, it will drive the gear 12 to rotate, and the gear 12 will drive the swing rod 11 to rotate. During the rotation of the swing rod 11, the scraper 18 will sweep and rotate with the swing rod 11 as the central axis. The scraper 18 will gradually pass through the upper surface of the forging table 3 when rotating and sweeping, and because the bottom of the scraper 18 is flush with the top of the forging table 3, the scraper 18 can sweep away the slag on its surface when sweeping the top surface of the forging table 3, thereby ensuring that the next time the mold is placed on the top of the forging table 3, the surface of the forging table 3 is in a clean state, avoiding the residue of slag causing defects, cracks and other problems on the mold surface.

[0049] like Figure 4 and Figure 7 As shown, an annular groove 24 is provided on the inner wall of the top surface of the workbench 1, and the arc-shaped toothed belt 13 is located directly above the annular groove 24. Two inner slide columns 14 are fixedly connected to the bottom of the arc-shaped toothed belt 13, and the outer walls of the two inner slide columns 14 are slidably connected to the inner wall of the annular groove 24, and a rubber elastic tube 15 is fixedly connected between the two inner slide columns 14.

[0050] During operation: when the pushing component pushes one end of the arc-shaped toothed belt 13, the arc-shaped toothed belt 13 will mesh with the gear 12, and the moving route of the arc-shaped toothed belt 13 is consistent with the inner wall of the inner slide column 14 in the annular slide groove 24. After the pushing component pushes the arc-shaped toothed belt 13 to a certain position, it will not be able to contact and push the arc-shaped toothed belt 13, and at this time, the gear 12 can just rotate 90 degrees to complete the cleaning work.

[0051] like Figures 3 to 6As shown, the pushing assembly includes an articulated seat 8, a connecting rod 7 is fixedly connected to the top of the articulated seat 8, a bottom slide groove 6 is provided on the bottom inner wall of one of the electric sliders 5, the outer wall of the connecting rod 7 is slidably connected to the bottom slide groove 6 and is adapted to each other, the top of the connecting rod 7 is fixedly connected to the top of one of the electric sliders 5, a T-block 9 is fixedly connected to the bottom of the articulated seat 8, a T-slot 10 is provided on the top inner wall of the workbench 1, the T-block 9 and the T-slot 10 are slidably connected and adapted to each other, an articulated rod 19 is fixedly connected to the outer wall of the shaft rod of the articulated seat 8, one end of the articulated rod 19 is fixedly connected to a push block 20, one side of the articulated rod 19 is fixedly connected to a limiting block 21, and one side of the articulated seat 8 is fixedly connected to a blocking column 22.

[0052] During operation: when the electric slider 5 slides inside the inner slide seat 4 so that the mold leaves the forging table 3, the articulated seat 8 will be driven to move through the connecting rod 7, and the articulated seat 8 will slide along the inner wall of the T-shaped slide groove 10 through the T-shaped block 9. When the push block 20 moves to one end of the arc-shaped toothed belt 13 and contacts it, the push block 20 will squeeze and push the arc-shaped toothed belt 13 to move in the moving direction, and through the restrictions of the limit block 21 and the blocking column 22, the articulated rod 19 and the push block 20 push one end of the arc-shaped toothed belt 13 forward. When moving, there will be no hinge movement in the extrusion direction between the articulated seat 8 and the articulated rod 19, and the push block 20 can push the arcuate toothed belt 13 to engage with the gear 12. The position of the arcuate toothed belt 13 will gradually change during the pushing process, and finally the push block 20 will not be able to contact the arcuate toothed belt 13. At this time, the meshing relationship between the arcuate toothed belt 13 and the gear 12 can just drive the gear 12 to rotate 90 degrees, so that the scraper 18 rotates 90 degrees with the swing rod 11 as the center axis to remove the slag above the forging table 3.

[0053] like Figures 3 to 6 As shown, a damping rod 17 is fixedly connected to one side of one of the inner sliding columns 14, a return spring 16 is arranged outside the damping rod 17, one end of the return spring 16 is fixedly connected to the outer wall of the inner sliding column 14, and the other end of the return spring 16 is fixedly connected to the inner wall of the annular slide groove 24, and a return spring 23 is fixedly connected between the push block 20 and the side of the hinge seat 8.

[0054] During operation: after the push block 20 pushes the arc-shaped toothed belt 13 to move, when the articulated seat 8 continues to slide in the inner wall of the T-shaped slide 10, the arc-shaped toothed belt 13 and the inner slide column 14 can automatically reset under the action of the reset spring 16 and the damping rod 17. The arc-shaped toothed belt 13 will drive the gear 12 to rotate in the opposite direction again during the reset process. Therefore, the scraper 18 will reset during the reverse rotation of the gear 12, which will not prevent the mold from returning to the top of the forging table 3, and it will also facilitate the next cleaning work. When controlling the electric slide 5 to slide inside the inner slide seat 4 to drive the mold to reset, the scraper 18 will reset in the process of the reverse rotation of the gear 12. In the process of returning to the top of the forging table 3, the articulated seat 8 can move in the opposite direction along the inner wall of the T-shaped slide groove 10. At this time, since the arc-shaped toothed belt 13 has been reset and is restricted by the annular slide groove 24, when the push block 20 contacts the outer wall of the arc-shaped toothed belt 13, it cannot drive the arc-shaped toothed belt 13 to move, and will squeeze the reset spring 23 inward and cause the articulated rod 19 and the articulated seat 8 to articulate and rotate, and the push block 20 will reset along the outer wall of the arc-shaped toothed belt 13. When the articulated seat 8 returns to its original position, the cleaning assembly and the pushing assembly are both reset to facilitate the next cleaning work.

[0055] like Figures 8 to 10 As shown, the clamping assembly includes two clamping heads 27, the inner walls of the two electric sliders 5 are rotatably connected with a rotating rod 25, one end of each rotating rod 25 is fixedly connected with a telescopic rod 26, and one end of each telescopic rod 26 is fixedly connected to the sides of the two clamping heads 27.

[0056] During operation: when the forging die is placed on top of the forging table 3, the two telescopic rods 26 are controlled to make the two clamping heads 27 move closer to each other, and the two clamping heads 27 will eventually contact the outer wall of the die to achieve a clamping effect.

[0057] like Figures 8 to 9 As shown, the flip assembly includes two gears 28, and the sides of the two inner slide seats 4 are provided with side slide grooves 29. The rotating rod 25 and the side slide grooves 29 are slidably connected and adapted to each other. The two gears 28 are respectively fixedly installed on the outer walls of the two rotating rods 25, and the bottoms of the two inner slide seats 4 are fixedly connected with connecting members 30, and one side of the connecting member 30 is fixedly connected with a fixing rod 35. The outer wall of the fixing rod 35 is slidably connected with an iron block 32, and the top of the iron block 32 is fixedly connected with a rack plate 31. The number of teeth of the rack plate 31 is half the number of teeth of the gear 28.

[0058] During operation: when the electric slider 5 slides on the inner wall of the inner slide seat 4, the gear 2 28 will mesh with the rack plate 31, and because the number of teeth on the rack plate 31 is half of the number of teeth on the gear 2 28, the rack plate 31 can make the gear 28 rotate 180 degrees during the sliding process, and the gear 2 28 will make the rotating rod 25 rotate 180 degrees, and use the telescopic rod 26 and the clamping head 27 to make the mold rotate 180 degrees, thereby achieving the effect of flipping the mold, and the flipped mold can be forged on the other side.

[0059] like Figures 8 to 9 As shown, one end of the fixing rod 35 is fixedly connected to the electromagnet 34, and the outer wall of the fixing rod 35 is provided with a return spring 33, one end of the return spring 33 is fixedly connected to one end of the iron block 32, and the other end of the return spring 33 is fixedly connected to one side of the electromagnet 34.

[0060] When working: in the initial state, the rack plate 31 and the gear 2 28 maintain the same horizontal position. After the rack plate 31 and the gear 2 28 are in meshing relationship, the inner slide seat 4 is installed to continue to slide so that the electromagnet 34 is energized. After the electromagnet 34 is energized, it can generate an adsorption force on the iron block 32, so that the iron block 32 slides along the outer wall of the fixing rod 35. After the iron block 32 slides, the rack plate 31 and the gear 2 28 will not be kept in the same horizontal line. During the resetting process of the gear 2 28, it will not mesh with the rack plate 31. Therefore, the mold will not flip over again during the resetting process after flipping. When the reset of the inner slide seat 4 is completed, the control electromagnet 34 is powered off. At this time, under the action of the reset spring three 33, the iron block 32 and the rack plate 31 can be reset, which is convenient for the next use.

[0061] A forging equipment for large die forging is proposed. The forging process suitable for the equipment is proposed:

[0062] S1. Before forging, heat the die to be forged at high temperature;

[0063] S2, placing the die on the forging table 3, first clamping the die by a clamping assembly, and then starting to continuously forge the top surface of the die;

[0064] S3, after one side of the die is forged, the die is transported to one end of the forging table 3 by the flipping assembly and the die is flipped, and the bottom and top surfaces of the die are swapped after flipping;

[0065] S4. During the turning process, the slag remaining on the forging table 3 during the forging process can be cleaned by the cleaning component;

[0066] S5, the die is flipped over and reset to return to the forging table 3 to continue forging. After the forging is completed again, the die is flipped over again to forge again. This is repeated many times to forge the die into a finished product.

[0067] S6. After forging, the mold is transported to the cooling table 2 for cooling to form a fixed shape and then taken out.
