Forging is performed using a forging press. When using a forging press to process aluminum alloy forgings, it is necessary to process the aluminum alloy forgings in a low-heat state.

[0003] During the processing, most equipment uses hydraulic cylinders to stamp aluminum alloy forgings. Since the hydraulic cylinder is formed once during the forging process of aluminum alloy forgings, a single forging will produce great stress on the surface of the high-strength aluminum alloy, causing the surface of the aluminum alloy forgings to be distorted or even broken under the action of stress.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 8 , a processing device for aluminum alloy forgings, including a forging machine body 1, the top of the forging machine body 1 is fixedly connected to a forging frame 5, two groups of forging units 6 are fixedly arranged on the forging frame 5, the forging unit 6 includes a cylinder 7 fixedly installed on the top of the forging frame 5, and the telescopic end of the cylinder 7 passes through the forging frame 5 and is fixedly connected to a rectangular plate 9, a plurality of groups of guide rods 8 are fixedly arranged between the forging frame 5 and the forging machine body 1, each group of guide rods 8 passes through the rectangular plate 9, and the guide rods 8 have a sliding guiding effect on the rectangular plate 9, a first driving motor 4 is fixedly installed on the outer surface of the forging machine body 1, two groups of sprocket wheels 2 are rotatably arranged inside the forging machine body 1, the outer surfaces of the two groups of sprocket wheels 2 are sleeved with chains 3, and the two groups of sprocket wheels 2 are driven by the chains 3, the output end of the first driving motor 4 is fixedly connected to one of the groups of sprocket wheels 2, a total of two groups of forging units 6 are arranged and are distributed left and right, a pre-forging assembly 10 is fixedly arranged at the bottom of one of the forging units 6, and a continuous forging assembly 11 is fixedly arranged at the bottom of the other forging unit 6.

[0021] The pre-forging assembly 10 includes a water tank 34 fixedly installed at the bottom of one group of rectangular plates 9, a pressure chamber 12 is opened in the water tank 34, the inner wall of the pressure chamber 12 is fixedly connected to a limiting ring 13, the limiting ring 13 divides the pressure chamber 12 into a lower circular chamber 14 and an upper circular chamber 15, a forging column 16 is provided with a sliding seal in the lower circular chamber 14, and the limiting ring 13 limits the forging column 16.

[0022] The continuous forging assembly 11 includes a second driving motor 24 embedded in another set of rectangular plates 9 . The output end of the second driving motor 24 extends to the bottom of the rectangular plates 9 and is fixedly connected to the forging head 25 .

[0023] A receiving plate 35 is fixedly provided on the inner wall of the forging machine body 1. The receiving plate 35 is used to support the chain 3. The chain 3 is used to transport the aluminum alloy forgings.

[0024] When it is necessary to process the aluminum alloy forgings, first place the aluminum alloy forgings on the forging machine body 1, then the first drive motor 4 is started, and under the transmission action of the two sets of sprockets 2, the aluminum alloy forgings are transported to the bottom of the pre-forging assembly 10 through the chain 3, then the chain 3 stops transporting the aluminum alloy forgings, and the cylinder 7 works and extends through the rectangular plate 9 to lower the entire pre-forging assembly 10 until the forging column 16 begins to contact the surface of the aluminum alloy forgings, at this time, as the cylinder 7 descends, the forging column 16 moves upward in the lower circular cavity 14, and then under the limiting action of the limiting ring 13 on the forging column 16, the forging column 16 will leave a circle of shallow pits on the surface of the aluminum alloy forging, so that the subsequent forging assembly 11 continues to perform subsequent forging processing on the aluminum alloy forgings, and then the forging unit 6 moves up and resets the entire pre-forging assembly 10 through the contraction of the cylinder 7; After the pre-forging assembly 10 is reset, the first drive motor 4 works again, so that the chain 3 conveys the aluminum alloy forging to the bottom of the subsequent forging assembly 11. At this time, when the forging head 25 is aligned with the pit on the surface of the aluminum alloy forging processed by the forging column 16, the first drive motor 4 stops working, and then the aluminum alloy forging stops moving. At this time, the forging unit 6 works through the action of the cylinder 7 gradually extending, so that the forging head 25 gradually contacts the pit on the surface of the aluminum alloy forging. At the same time, the second drive motor 24 starts to work and rotates with the forging head 25 to perform forging and punching processing on the pit of the aluminum alloy forging. The processing of the pre-forging assembly 10 to press out the pit of the aluminum alloy forging facilitates the positioning of the subsequent forging assembly 11 for the aluminum alloy forging where it needs to be forged, and avoids the situation that the forging surface is deformed or even cracked due to the different pressures on the various parts of the aluminum alloy forging when the position where the aluminum alloy forging needs to be forged is not a horizontal plane; The conventional forging method of pressing holes in aluminum alloy forgings with one-time downward pressure will cause different stresses on the inner wall of the hole of the aluminum alloy forging due to the presence of an inclined surface at the forging position of the aluminum alloy forging. Due to the deformation and distortion of the inclined surface during forging, different stresses are generated on the inner wall of the hole of the aluminum alloy forging. As the forging depth increases, the probability of fracture at the forging position increases. The pre-forging component 10 can forge shallow pits on the surface of the aluminum alloy forging, thereby reducing the occurrence of fractures at the forging position of the forging component due to excessive stress generated during one-time forging. The use of graded forging can generate less stress on the surface of the aluminum alloy forging, making its force-bearing surface as uniform as possible in all directions, thereby reducing the scrap rate of the product and improving the production efficiency of the product.

[0025] like Figure 6 As shown, a circle of water chamber 17 is provided inside the water tank 34 . The water chamber 17 is outside the pressure chamber 12 . The water chamber 17 is connected to the pressure chamber 12 through a first one-way valve 18 . A second one-way valve 19 is fixedly installed at the bottom of the water chamber 17 .

[0026] First, when the forging column 16 gradually moves downward to contact the aluminum alloy forging, the forging column 16 will gradually move upward in the lower circular cavity 14, and push the gas in the lower circular cavity 14 into the upper circular cavity 15. Since the upper circular cavity 15 is connected to the water cavity 17, the gas in the lower circular cavity 14 pushes the gas in the upper circular cavity 15 into the water cavity 17, and squeezes the water flow in the water cavity 17 to flow out through the second one-way valve 19 and drip on the surface of the aluminum alloy forging. When the forging column 16 performs forging processing on the aluminum alloy forging, the tension generated by the forging column 16 when processing the aluminum alloy forging is reduced by the tension of the water flow, and the deformation and cracking of the aluminum alloy forging due to uneven surface force during forging are reduced, thereby further reducing the scrap rate of the product and improving the production efficiency of the product. The aluminum alloy processed by the pre-forging assembly 10 will squeeze out a part of the water flow after working, and the water flow will flow into the groove on the surface of the aluminum alloy forging due to its own gravity. Then, in the subsequent process of the forging head 25 processing the aluminum alloy forging, the water flow in the groove will also reduce the stress generated during forging, and this part of the water will mix the debris generated by the forging head 25 during forging, thereby reducing the splashing of the aluminum alloy forging debris when the forging head 25 rotates. It should be noted that the water spraying direction of the second one-way valve 19 is the bottom of the forging column 16, and the flow rate of the water flow can be adjusted by controlling the speed of the forging unit 6 moving downward; The first one-way valve 18 allows the gas in the upper circular cavity 15 to enter the water cavity 17 , and the second one-way valve 19 allows the water in the water cavity 17 to flow out of the water cavity 17 .

[0027] like Figure 6As shown, a first thrust spring 20 is arranged inside the pressure chamber 12, the top end of the first thrust spring 20 is fixedly connected to the inner wall of the top of the upper circular chamber 15, the bottom end of the first thrust spring 20 is fixedly connected to the forging column 16, the upper circular chamber 15 is connected to the outside of the water tank 34 through a third one-way valve 22, an external water pipe 21 is fixedly inserted into the inner wall of the water chamber 17, the external water pipe 21 can supply water to the inside of the water chamber 17 through an external water pump, and a water pressure sensor 23 is fixedly installed on the inner wall of the water chamber 17; The horizontal height of the inner wall at the top of the upper circular cavity 15 is greater than the horizontal height of the inner wall at the top of the water cavity 17 . In a static state, the forging column 16 has the same volume as that inside the lower circular cavity 14 and the volume in the water cavity 17 below the water pressure sensor 23 .

[0028] After the forging column 16 completes the processing of the aluminum alloy forging, as the forging unit 6 moves upward, under the action of the first thrust spring 20, the forging column 16 will gradually separate from the limit ring 13 from the state of being close to the limit ring 13, so as to achieve the effect of moving downward and resetting in the lower circular cavity 14. When the forging column 16 moves downward in the lower circular cavity 14, the gas outside the water tank 34 is sucked into the pressure chamber 12 through the third one-way valve 22, so as to balance the air pressure in the pressure chamber 12. At the same time, under the action of the external water pump, water is pumped into the water chamber 17 through the external water pipe 21. When the horizontal position of the water reaches the water pressure sensor 23, the water pressure sensor 23 transmits a signal to the forging machine body 1, thereby stopping the external water pump, thereby realizing the resetting action of the pre-forging component 10 after processing the aluminum alloy forging, and improving the automation degree of the pre-forging component 10. It should be noted that the water pressure sensor 23 and the external water pump are both electrically connected to the forging machine body 1 and are controlled by the control system on the forging machine body 1; The third one-way valve 22 is used to draw external gas into the pressure chamber 12 to balance the internal air pressure of the pressure chamber 12 , thereby achieving the reset action of the pre-forging assembly 10 .

[0029] like Figure 8 As shown, the forging head 25 is divided into a plurality of groups of wide heads 26 and round heads 27 in order from large to small in size. The wide head 26 is located below the round head 27 . The wide head 26 is conical in shape, and the round head 27 is cylindrical in shape.

[0030] When a round hole is required at the forging position of an aluminum alloy forging, the wide head 26 can be used to drill in gradually, and the round head 27 can be used to round the round hole, so as to forge the required round hole step by step. When a wide-mouthed hole needs to be forged on an aluminum alloy forging, the wide-mouthed hole can be made on the aluminum alloy forging by drilling with the wide head 26. At the same time, since the forging head 25 is divided into multiple groups of wide heads 26 and round heads 27 in order from large to small in size, it can be suitable for processing more round holes and wide mouths of different sizes on the aluminum alloy forging. By adjusting the elongation of the cylinder 7, the purpose of increasing the size of the round hole and the wide mouth on the aluminum alloy forging can be achieved. It should be particularly noted here that the wide head 26 and the round head 27 of the forging head 25 are both drill bits.

[0031] like Figure 4 , Figure 7 and Figure 8 As shown, another group of rectangular plates 9 is fixedly connected to the bellows 28 at the bottom, an air suction cavity 29 is opened inside the bellows 28, and a plurality of groups of air suction pipes 30 connected to the air suction cavity 29 are fixedly inserted at the top of the bellows 28. Each group of air suction pipes 30 is symmetrically distributed on the bellows 28 in a circular shape, and each group of air suction pipes 30 is connected to an external air suction pump.

[0032] When the forging head 25 forges holes on the surface of the aluminum alloy forging by rotating, the forging machine body 1 controls the external suction pump to work, and sucks away the debris generated by the forging head 25 and melted in the water through the suction chamber 29, thereby reducing the friction of the debris generated by the forging head 25 on the hole wall, resulting in the hole wall being too large and uneven, further reducing the scrap rate, thereby further improving the production efficiency of the product; It should be noted that the distance between the bottom of the bellows 28 and the aluminum alloy forging is no more than 1 cm, so as to ensure that the bellows 28 has sufficient suction force to absorb the mixture of water and debris on the surface of the aluminum alloy forging.

[0033] like Figure 4 , Figure 7 and Figure 8 As shown, the bottom of the bellows 28 is fixedly connected to the ring plate 31, and the size of the ring plate 31 is larger than that of the bellows 28. A plurality of groups of second thrust springs 33 are equidistantly arranged on the circumference of the ring plate 31. Each group of second thrust springs 33 is used to connect the ring plate 31 and the rectangular plate 9. Two groups of L-shaped plates 32 are symmetrically arranged at the bottom of the other group of rectangular plates 9. The bottom ends of the two groups of L-shaped plates 32 are located at the bottom of the ring plate 31.

[0034] In order to ensure that the bellows 28 has sufficient suction force to absorb the mixture of water and debris on the surface of the aluminum alloy forging, when the forging head 25 gradually moves downward due to the processing of the aluminum alloy forging, under the action of the L-shaped plate 32, the distance between the ring plate 31 and the aluminum alloy forging is always kept constant. At the same time, after the continued forging assembly 11 is reset, under the action of the second thrust spring 33, the entire bellows 28 can be reset, which cooperates with the reset effect of the pre-forging assembly 10 to further improve the degree of automation of the device.

[0035] Usage: When it is necessary to process the aluminum alloy forgings, first place the aluminum alloy forgings on the forging machine body 1, and convey the aluminum alloy forgings to the bottom of the pre-forging assembly 10 through the chain 3. At this time, the chain 3 stops conveying the aluminum alloy forgings, and the cylinder 7 works and extends through the rectangular plate 9 to make the entire pre-forging assembly 10 descend. The forging column 16 will leave a circle of shallow pits on the surface of the aluminum alloy forgings, so that the subsequent forging assembly 11 can continue to perform subsequent forging processing on the aluminum alloy forgings. Then, the forging unit 6 moves the entire pre-forging assembly 10 upward and resets through the contraction of the cylinder 7. After the pre-forging assembly 10 is reset, the first drive motor 4 works again, so that the chain 3 transports the aluminum alloy forging to the bottom of the subsequent forging assembly 11. At this time, when the forging head 25 is aligned with the pit on the surface of the aluminum alloy forging processed by the forging column 16, the first drive motor 4 stops working, and then the aluminum alloy forging stops moving. At this time, the forging unit 6 works through the gradual extension of the cylinder 7, so that the forging head 25 gradually contacts the pit on the surface of the aluminum alloy forging. At the same time, the second drive motor 24 starts to work and rotates the forging head 25 to perform forging and hollowing processing on the pit of the aluminum alloy forging.

[0036] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
