Description

Technical Field

[0001] This invention relates to the field of aluminum alloy forging technology, and more specifically to an automated aluminum alloy scroll forging system. Background Technology

[0002] A scroll compressor is a device consisting of an involute rotating scroll and a stationary scroll that mesh together. During operation, the stationary scroll is fixed to the frame, while the rotating scroll is driven by an eccentric shaft and moves around the center of the stationary scroll in a small-amplitude planar rotation.

[0003] Scroll compressors are positive displacement compressors characterized by high energy efficiency, low noise, stable operation, and relatively simple structure. They are widely used in fields such as air conditioning for new energy vehicles and air compressors, and the scroll plate is one of the key components.

[0004] In existing scroll plate manufacturing processes, aluminum alloy is often forged into a scroll plate structure. However, due to the inherent properties of aluminum alloy, its high thermal conductivity and low melting point create a space between the bottom of the workpiece and the mold during forging. Under significant impact pressure, gases inside the mold can easily become trapped between the mold and the workpiece, causing porosity during forging. This results in defects in the forged scroll plate and reduced forging quality. Furthermore, the workpiece is prone to positional deviations due to the high impact pressure, reducing forging accuracy. After forging, the aluminum alloy scroll plate tends to stick to the mold, making demolding difficult and requiring manual hammering for release – a time-consuming, labor-intensive, and cumbersome process.

[0005] In view of this, and to address the aforementioned shortcomings, this invention develops an automated aluminum alloy scroll plate forging system. Summary of the Invention

[0006] The technical problem to be solved by the present invention is that in the manufacturing process of existing scroll plates, the gas inside the mold is easily sealed between the mold and the aluminum alloy workpiece, which will lead to the generation of air holes during forging. At the same time, due to the large impact force, the position of the workpiece is prone to deviation during forging, and the aluminum alloy scroll plate sticks to the mold after forging, making demolding difficult.

[0007] This invention provides the following technical solution: an automated aluminum alloy scroll forging system, comprising a forging machine body, a housing, a suction assembly, an auxiliary assembly, and a control assembly; the housing is fixedly mounted on the forging machine body, the housing being a hollow structure, and a suction assembly is fixedly mounted on the bottom of the housing. The suction assembly extracts gas from inside the mold by moving the forging machine body up and down, then injects gas and pushes the workpiece in the mold. The assembly can be connected by bolts or welding. An auxiliary assembly is fixedly mounted on the top of the housing; the auxiliary assembly positions the workpiece and demolds it by moving the forging machine body up and down. This auxiliary assembly can also be connected by bolts or welding. The forging machine body is electrically connected to the control assembly.

[0008] During the forging process of aluminum alloy scroll plates, the gas inside the lower die can easily cause porosity in the forged scroll plate. To avoid the gas affecting the workpiece during forging, a suction component is used to extract the gas from the lower die during the forging process. This prevents the gas inside the lower die from causing porosity in the forged scroll plate. After forging, when demolding, the suction component injects gas into the lower die, so that the workpiece on the lower die is subjected to an upward thrust, preventing the workpiece from sticking to the die and facilitating demolding. At the same time, an auxiliary component can be used to position and fix the workpiece to be forged, and after forging, the forged workpiece can be quickly demolded.

[0009] The suction assembly includes an upper mold, a lower mold, an air tube, a piston, a connecting rod, a U-shaped rod, a ring, and a linkage rod. Multiple air holes are formed on both sides of the bottom of the lower mold, with diameters between 0.5-1 mm. The distance between two adjacent air holes is five times the diameter of the air hole. A circular through-hole is formed in the center of the lower mold. The lower mold is fixedly mounted on a housing. Air tubes are fixedly mounted on both sides of the bottom of the lower mold, and these connections can be made by bolting or welding. A piston is movably mounted inside the air tube. A connecting rod is fixedly mounted at the bottom of the piston. The bottom of the connecting rod is fixedly mounted in the middle of the U-shaped rod. A ring is fixedly mounted at the top of the U-shaped rod, located on the outer surface of the air tube. The bottom of the linkage rod is fixedly mounted between two rings. The upper mold is fixedly mounted at the top of the linkage rod, and the linkage rod is located within the circular through-hole. These connections can also be made by bolting or welding.

[0010] To ensure the suction assembly can quickly extract gas, the downward movement of the upper mold is transmitted to the suction assembly. The piston on the suction assembly moves within the air pipe, drawing air out of the lower mold. The diameter of the vent holes is between 0.5-1mm to prevent impurities from entering during forging, and also to prevent the forged workpiece from entering the vent holes. The distance between two adjacent vent holes is five times the diameter of the vent hole, ensuring that all gas is quickly extracted from the lower mold during forging. Furthermore, during demolding after forging, this allows gas to quickly enter the lower mold, and the bottom of the workpiece receives a uniform upward thrust. As gas enters, the air pressure at the bottom of the workpiece increases, pushing the workpiece and accelerating demolding efficiency.

[0011] It is important to note that when extracting gas from the lower mold, a piston is used for gas extraction, and both the piston and the gas pipe must be made of high-temperature resistant materials. This is because the lower mold needs to be maintained within a certain temperature range during forging. If the temperature is too low or too high, it will affect the forging efficiency and the forging quality.

[0012] The lower mold has a circular groove at the top, and an annular groove is formed radially outward from the top of the circular groove. Circular holes are formed on both sides of the annular groove. Spiral protrusions are provided inside the circular groove. Air holes are located between the spiral protrusions, and multiple air holes are arranged in a spiral shape along the spiral protrusions. A connecting pipe is fixedly installed at the bottom of the air hole, and the connecting pipe is connected to the air pipe. The diameter of the circular hole is 3 / 4 of the difference between the outer diameter and the inner diameter of the annular groove. The ratio of the width of the spiral protrusion to the distance between adjacent spiral protrusions is 3:2. The specific installation method can be to connect by bolts or welding.

[0013] The circular groove on the lower die is used to place the workpiece to be forged. The spiral protrusions inside the circular groove are used to forge the scroll plate. The air holes are located between the spiral protrusions. This is to prevent the spiral protrusions from being damaged due to excessive pressure during forging. At the same time, when the gas is compressed, it will be distributed between the spiral protrusions to prevent incomplete gas extraction. Finally, the gas from each air hole is gathered through a connecting pipe and drawn into the air pipe. The diameter of the circular hole is 3 / 4 of the difference between the outer diameter and the inner diameter of the annular groove. This is to allow for a sufficiently large circular hole to be opened in the annular groove to support the movement of the ring. The ratio of the width of the spiral protrusion to the distance between adjacent spiral protrusions is 3:2 to ensure that the forged scroll plate can meet certain precision requirements during forging.

[0014] The length of the trachea is 2:5 to the height of the box, the diameter of the trachea is between 2 and 5 cm, and the ratio of the diameter of the trachea to the diameter of the connecting pipe is 5:1.

[0015] To ensure all the gas inside the lower mold is extracted into the air pipe, the piston needs a certain stroke to move. Sufficient space is required for the piston to move. The ratio of the air pipe length to the height of the housing is 2:5 to allow for sufficient movement of the connecting rod connected to the piston, enabling the piston to slide from the top to the bottom of the air pipe. When the air pipe diameter is less than 2cm, the volume of gas extracted from the lower mold will decrease, and the extraction speed will be slower, failing to meet the extraction requirements. While a diameter greater than 5cm increases the volume of gas extracted, excessive gas will lead to slow exhaust. The ratio of the air pipe diameter to the connecting pipe diameter is 5:1 to ensure increased exhaust pressure, allowing the gas to be discharged under high pressure and push the workpiece on the lower mold for demolding, thus improving demolding efficiency.

[0016] The width of the U-shaped rod is 1.2 times the diameter of the trachea, the length of the U-shaped rod is in the ratio of 4:5 to the length of the trachea, and the height of the U-shaped rod is equal to the length of the connecting rod.

[0017] Because the U-shaped rod needs to slide on the trachea, it ensures the piston can make stable vertical reciprocating motion during movement. The U-shaped rod enhances the piston's stability during operation. Due to the different directions of force, the width of the U-shaped rod is 1.2 times the diameter of the trachea to ensure that the U-shaped rod can move outside the trachea and drive the piston. The ratio of the length of the U-shaped rod to the length of the trachea is 4:5 to ensure that the piston has a larger stroke when moving in the trachea. The increased stroke means a larger space inside the trachea, which will increase the amount of gas that can be extracted and discharged. The height of the U-shaped rod is equal to the length of the connecting rod, ensuring that the movement distance of the U-shaped rod and the piston are equal.

[0018] A rectangular block is fixedly installed at the bottom of the linkage rod, and the two ends of the rectangular block are fixedly installed between two rings; a trapezoidal tooth is opened at the bottom 1 / 3 of the linkage rod; the length of the linkage rod is telescopic, and the shortest distance of the linkage rod is the height of the lower mold.

[0019] When the connecting rod is driven by the upper mold and moves downward, it transmits force to the rectangular block, which then evenly transmits the force to the two rings, causing them to move on the air pipe. This prevents the rings from tilting and jamming due to uneven force distribution, and also avoids damage to the outer wall of the air pipe. The trapezoidal teeth at the bottom third of the connecting rod are used to transmit the force to the auxiliary components. The connecting rod moves with the upper mold, and the upper part of the connecting rod is usually on the outer surface. To facilitate the placement of the workpiece to be forged, the upper mold needs to move upward a considerable distance. The length of the connecting rod is extendable, and the shortest distance of the connecting rod is the height of the lower mold, which ensures the smooth sliding of the connecting rod on the lower mold.

[0020] The auxiliary components include a gear column, a gear disc, a rotating shaft, a ring sleeve, a rack, and a slide rod. The rotating shaft is horizontally rotatable inside the housing. A gear column is fixedly mounted on the rotating shaft, and a gear disc is fixedly mounted at one end of the gear column. The ring sleeve is located within an annular groove, and a slide rod is fixedly mounted on one side of the bottom of the ring sleeve, with the slide rod located within a circular hole in the annular groove. The length of the slide rod is 2 / 3 of the length of the rack. A rack is fixedly mounted on the other side of the ring sleeve. The rack can be connected by bolts or welding. The rack meshes with the gear disc, and the width of the gear disc is equal to the width of the rack. The gear column meshes with the trapezoidal teeth on the bottom of the connecting rod, and the length of the gear column is equal to the width of the trapezoidal teeth on the bottom of the connecting rod.

[0021] It should be noted that during forging, the workpiece to be forged needs to be positioned. To prevent deviations during forging, the power is transmitted to the ring sleeve via a connecting rod through a toothed column. This allows the ring sleeve to move downwards with the movement of the lower die, keeping the workpiece in a vertical position. After forging, the workpiece needs to be clamped mechanically or manually. However, some workpieces stick to the lower die after forging and cannot be quickly demolded. The upward movement of the connecting rod moves the ring sleeve upwards, allowing the workpiece to be quickly demolded. The length of the slide bar is 2 / 3 of the length of the rack. The slide bar is used to stabilize the up-and-down movement of the ring sleeve, preventing it from shifting during movement. The width of the toothed disc is equal to the width of the rack, and the length of the toothed column is equal to the width of the trapezoidal teeth at the bottom of the connecting rod. This is to enable the force on the connecting rod to be quickly transmitted to the auxiliary components, making the force transmission more stable. At the same time, the slide bar enhances the stability of the ring sleeve sliding on the lower die, preventing the ring sleeve from shifting during up-and-down movement.

[0022] The thickness of the ring sleeve is equal to the height of the annular groove, and the outer diameter of the ring sleeve is equal to the diameter of the annular groove. The thickness of the ring sleeve is to ensure that it is on the same horizontal line as the top of the lower mold, so as to avoid the difference in height affecting the forging accuracy. The outer diameter of the ring sleeve is equal to the diameter of the annular groove so that the ring sleeve and the annular groove can fit together.

[0023] A circular groove is horizontally formed around the inner side of the ring. A compression spring is fixedly installed in the circular groove. A sleeve is fixedly installed on the outer surface of the outer end of the compression spring. The length of the sleeve is equal to the difference between the inner diameter and the outer diameter of the ring. The specific installation method can be bolt connection or welding.

[0024] To ensure that the workpiece does not shift during positioning, a pressure spring installed inside the sleeve positions the workpiece to be forged. This ensures that the workpiece is subjected to equal pressure around its perimeter during forging. Furthermore, the workpiece will undergo radial deformation under pressure during forging, compressing the spring and causing the sleeve to enter the circular groove, thus ensuring the workpiece is positioned during forging.

[0025] An elastic ring is fixedly installed on the outer end of the sleeve. The specific installation method can be bolt connection or welding. The maximum diameter of the elastic ring is the inner diameter of the ring sleeve, and the minimum diameter of the elastic ring is the diameter of the aluminum alloy rod.

[0026] After forging, the elastic ring on the outer side of the sleeve contacts the workpiece and is clamped by the pressure of the compression spring. As the upper die moves upward, the workpiece can be quickly demolded. The maximum diameter of the elastic ring is the inner diameter of the sleeve to match the formed workpiece, while the minimum diameter of the elastic ring is the diameter of the aluminum alloy rod. To position the forged aluminum alloy rod workpiece, the elastic sheet is made of high-temperature resistant material and has a certain elasticity at high temperatures. Because the aluminum alloy raw material needs to be heated to a certain temperature before forging, and the aluminum alloy workpiece needs to be positioned by the sleeve, it is necessary to use high-temperature resistant material to increase its service life.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. This invention, by setting a suction component on the box body, and through the cooperation between the forging machine body and the suction component, extracts the gas inside the mold during forging, preventing the internal gas from causing porosity in the forged workpiece, thus improving the quality of forging. At the same time, after forging is completed, the workpiece can be quickly demolded by injecting gas.

[0029] 2. By providing auxiliary components on the housing, the forging machine body and the auxiliary components work together to position the workpiece during forging, and prevent the workpiece from shifting due to excessive impact pressure during forging, thereby improving forging accuracy and efficiency.

[0030] 3. The present invention provides a ring and a sleeve on the auxiliary component. Through the cooperation of the compression springs inside the ring and the sleeve, a clamping force can be applied to the forged workpiece after forging, which can realize the rapid and automatic demolding of the workpiece. At the same time, the clamping force can also fix the workpiece during forging, so that the position of the workpiece will not shift. Attached Figure Description

[0043] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0044] like Figures 1 to 5 As shown, an automated aluminum alloy scroll forging system includes a forging machine body 1, a housing 2, a suction assembly 3, an auxiliary assembly 4, and a control assembly. The housing 2 is fixedly mounted on the forging machine body 1. The housing 2 is a hollow structure. The suction assembly 3 is fixedly mounted on the bottom of the housing 2. The suction assembly 3 extracts gas from inside the mold by moving the forging machine body 1 up and down, then injects gas and pushes the workpiece in the mold. The assembly is installed using bolts. The auxiliary assembly 4 is fixedly mounted on the top of the housing 2. The auxiliary assembly 4 positions the workpiece and demolds it by moving the forging machine body 1 up and down. The assembly is also installed using bolts. The forging machine body 1 is electrically connected to the control assembly.

[0045] During aluminum alloy scroll plate forging, the control component controls the start of the forging machine body 1. Driven by the forging machine body 1, the suction component 3 starts to move. During forging, the suction component 3 extracts the air from the bottom of the mold. The auxiliary component 4 positions the workpiece. After forging, the suction component 3 blows air into the bottom of the mold to push the workpiece to move. The auxiliary component 4 then removes the workpiece, achieving rapid demolding.

[0046] like Figures 1 to 8As shown, the suction assembly 3 includes an upper mold 31, a lower mold 32, an air pipe 33, a piston 34, a connecting rod 35, a U-shaped rod 36, a ring 37, and a connecting rod 38. The lower mold 32 has multiple air holes 321 on both sides of its bottom. The diameter of each air hole 321 is between 0.5-1 mm, and the distance between two adjacent air holes 321 is five times the diameter of the air hole 321. A circular through hole 322 is formed in the center of the lower mold 32. The lower mold 32 is fixedly mounted on the housing 2, and air pipes 3 are fixedly mounted on both sides of the bottom of the lower mold 32. 3. The specific installation method adopts welding connection; a piston 34 is movably installed inside the air pipe 33, a connecting rod 35 is fixedly installed at the bottom of the piston 34, the bottom of the connecting rod 35 is fixedly installed in the middle of the U-shaped rod 36, a ring 37 is fixedly installed at the top of the U-shaped rod 36, the ring 37 is located on the outer surface of the air pipe 33, and the bottom of the connecting rod 38 is fixedly installed between the two rings 37; an upper mold 31 is fixedly installed at the top of the connecting rod 38, and the connecting rod 38 is located in the circular through hole 322. The specific installation method adopts bolt connection.

[0047] When the forging machine body 1 starts moving through the control components, the upper mold 31 on the suction component 3 will move downward along with the forging machine body 1. The upper mold 31 will drive the connecting rod 38 to move downward, and drive the rectangular block 381 at the bottom to move downward. The rectangular block 381 will drive the ring 37 to move downward. The ring 37 moves downward on the outer surface of the air pipe 33, and at the same time drives the connecting rod 35 on the U-shaped rod 36 to move downward. The piston 34 at the top of the connecting rod 35 slides inside the air pipe 33, thereby drawing out the air inside the lower mold 32.

[0048] After forging is completed, the upper mold 31 on the suction assembly 3 will move upward with the forging machine body 1. The upper mold 31 will drive the connecting rod 38 to move upward, and drive the rectangular block 381 at the bottom to move upward. The rectangular block 381 will drive the ring 37 to move upward. The ring 37 moves upward on the outer surface of the air pipe 33, and at the same time drives the connecting rod 35 on the U-shaped rod 36 to move upward. The piston 34 at the top of the connecting rod 35 slides inside the air pipe 33, thereby injecting air into the lower mold 32.

[0049] like Figure 7 and Figure 8As shown, the lower mold 32 has a circular groove 323 on its top, and an annular groove 324 is formed radially outward from the top of the circular groove 323. Circular holes 325 are formed on both sides of the annular groove 324. Spiral protrusions 326 are provided inside the circular groove 323. Air holes 321 are located between the spiral protrusions 326, and multiple air holes 321 are arranged in a spiral shape along the spiral protrusions 326. A connecting pipe 327 is fixedly installed at the bottom of the air holes 321, and the connecting pipe 327 is connected to the air pipe 33. The diameter of the circular hole 325 is 3 / 4 of the difference between the outer diameter and the inner diameter of the annular groove 324. The ratio of the width of the spiral protrusion 326 to the distance between adjacent spiral protrusions 326 is 3:2. The specific installation method is to connect them by welding.

[0050] The length of the air pipe 33 is 2:5 to the height of the housing 2, the diameter of the air pipe 33 is between 2 and 5 cm, and the ratio of the diameter of the air pipe 33 to the diameter of the connecting pipe 327 is 5:1; the width of the U-shaped rod 36 is 1.2 times the diameter of the air pipe 33, the length of the U-shaped rod 36 is 4:5 to the length of the air pipe 33, and the height of the U-shaped rod 36 is equal to the length of the connecting rod 35; during the forging process, the U-shaped rod 36 transmits power to the piston 34 through the connecting rod 35, driving the piston 34 to reciprocate.

[0051] As the forging machine body 1 operates, when the air inside the upper and lower molds 32 of the suction assembly 3 is extracted, the air will be drawn out from the air holes 321 between the spiral protrusions 326 on the lower mold 32 and flow into the air pipe 33 through the connecting pipe 327. During the operation of the suction assembly 3 with the forging machine body 1, the piston 34 will move back and forth in the air pipe 33 to extract and release the air inside the lower mold 32.

[0052] like Figure 4 and Figure 5 As shown, a rectangular block 381 is fixedly installed at the bottom of the linkage 38, and the two ends of the rectangular block 381 are fixedly installed between two rings 37; a trapezoidal tooth 382 is provided at the bottom 1 / 3 of the linkage 38; the length of the linkage 38 is telescopic, and the shortest distance of the linkage 38 is the height of the lower mold 32.

[0053] When the linkage 38 is subjected to force and moves upward or downward, the linkage 38 can transmit power to the rectangular block 381, causing the rectangular block 381 to move upward or downward. At the same time, the rectangular block 381 will cause the ring 37 to move upward or downward.

[0054] like Figure 4 , Figure 5 , Figure 9 and Figure 10As shown, the auxiliary component 4 includes a gear column 41, a gear disc 42, a rotating shaft 43, a ring sleeve 44, a rack 45, and a slide rod 46. The rotating shaft 43 is horizontally rotatably installed inside the housing 2. The gear column 41 is fixedly installed on the rotating shaft 43. The gear disc 42 is fixedly installed at one end of the gear column 41. The ring sleeve 44 is located in an annular groove 324. The slide rod 46 is fixedly installed on one side of the bottom of the ring sleeve 44, and the slide rod 46 is located in a circular hole 325 on the annular groove 324. The length of the slide rod 46 is 2 / 3 of the length of the rack 45. The rack 45 is fixedly installed on the other side of the ring sleeve 44. The rack 45 is connected by welding. The rack 45 meshes with the gear disc 42. The width of the gear disc 42 is equal to the width of the rack 45. The gear column 41 meshes with the trapezoidal teeth 382 on the bottom of the connecting rod 38, and the length of the gear column 41 is equal to the width of the trapezoidal teeth 382 on the bottom of the connecting rod 38.

[0055] During the forging process, when the forging machine body 1 drives the connecting rod 38 on the suction assembly 3 to move downward, the trapezoidal teeth 382 on the connecting rod 38 will drive the meshing tooth column 41 to rotate. The rotation of the tooth column 41 will drive the toothed disc 42 to rotate, and the toothed disc 42 will drive the meshing rack 45 to move downward. The rack 45 will drive the ring sleeve 44 to move downward. At the same time, the sliding rod 46 on the ring sleeve 44 will slide downward in the circular hole 325 on the annular groove 324, thereby achieving the positioning of the workpiece during forging.

[0056] When the forging machine body 1 drives the connecting rod 38 on the suction assembly 3 to move upward, the trapezoidal teeth 382 on the connecting rod 38 will drive the meshing tooth column 41 to rotate in the opposite direction. The rotation of the tooth column 41 will drive the tooth disk 42 to rotate in the opposite direction, and the tooth disk 42 will drive the meshing rack 45 to move upward. The rack 45 will drive the ring sleeve 44 to move upward. At the same time, the sliding rod 46 on the ring sleeve 44 will slide upward in the round hole 325 on the annular groove 324, thereby realizing the demolding of the workpiece after forging.

[0057] The thickness of the ring sleeve 44 is equal to the height of the annular groove 324, and the outer diameter of the ring sleeve 44 is equal to the diameter of the annular groove 324. The ring sleeve 44 will move with the movement of the connecting rod 38. When the ring sleeve 44 moves down to the lowest end, the top of the ring sleeve 44 will be level with the top of the lower mold 32.

[0058] like Figure 9 and Figure 10 As shown, a circular groove 441 is horizontally formed around the inner side of the ring 44. A compression spring 442 is fixedly installed in the circular groove 441. A sleeve 443 is fixedly installed on the outer surface of the outer end of the compression spring 442. The length of the sleeve 443 is equal to the difference between the inner diameter and the outer diameter of the ring 44. The specific installation method is bolt connection.

[0059] When the workpiece to be forged is placed inside the ring sleeve 44, the compression spring 442 on the ring sleeve 44 remains in its original state. As the forging machine body 1 runs, the workpiece will be compressed and forged. The ring sleeve 44 moves downward with the upper mold 31 until it moves to the top of the annular groove 324. At the same time, the compression spring 442 will also be compressed, and the sleeve 443 will slide into the circular groove 441 around the ring sleeve 44 to position the workpiece and prevent it from shifting during forging.

[0060] like Figure 9 and Figure 10 As shown, an elastic ring 444 is fixedly installed on the outer end of the sleeve 443, and the specific installation method is bolt connection; the maximum diameter of the elastic ring 444 is the inner diameter of the ring sleeve 44, and the minimum diameter of the elastic ring 444 is the diameter of the aluminum alloy rod.

[0061] After the workpiece is placed in the forging process, it is compressed into the sleeve 443 and then into the ring 44. Due to the elastic potential energy of the compression spring 442 inside the sleeve 443 and the elastic potential energy of the elastic ring 444, a clamping force is applied to the forged workpiece. As the upper mold 31 moves upward, the ring 44 moves upward through the connecting rod 38, thereby moving the workpiece upward and achieving rapid demolding of the workpiece.

[0062] In the overall working process, when forging aluminum alloy scroll discs, the control component controls the forging machine body 1 to start. Driven by the forging machine body 1, the upper die 31 on the suction component 3 will move downward with the forging machine body 1. The upper die 31 will drive the connecting rod 38 to move downward, and drive the rectangular block 381 at the bottom to move downward. The rectangular block 381 will drive the ring 37 to move downward. The ring 37 moves downward on the outer surface of the air pipe 33, and at the same time drives the connecting rod 35 on the U-shaped rod 36 to move downward. The piston 34 at the top of the connecting rod 35 slides inside the air pipe 33, thereby drawing out the air inside the lower die 32 through the air holes 321 between the spiral protrusions 326 on the lower die 32, and flowing into the air pipe 33 along the connecting pipe 327.

[0063] Furthermore, when the connecting rod 38 on the suction assembly 3 moves downward, the trapezoidal teeth 382 on the connecting rod 38 will drive the meshing tooth column 41 to rotate. The rotation of the tooth column 41 will drive the toothed disc 42 to rotate, and the toothed disc 42 will drive the meshing rack 45 to move downward. The rack 45 will drive the ring sleeve 44 to move downward. At the same time, the sliding rod 46 on the ring sleeve 44 will slide downward in the circular hole 325 on the annular groove 324. As the forging machine body 1 runs, the workpiece will be compressed and forged. The ring sleeve 44 moves downward with the upper mold 31 until it moves to the top of the annular groove 324. At the same time, the compression spring 442 will also be compressed, and the sleeve 443 will slide into the circular groove 441 around the ring sleeve 44 to position the workpiece and keep it from shifting during forging.

[0064] After forging is completed, the upper mold 31 on the suction assembly 3 will move upward with the forging machine body 1. The upper mold 31 will drive the connecting rod 38 to move upward, and drive the rectangular block 381 at the bottom to move upward. The rectangular block 381 will drive the ring 37 to move upward. The ring 37 moves upward on the outer surface of the air pipe 33, and at the same time drives the connecting rod 35 on the U-shaped rod 36 to move upward. The piston 34 at the top of the connecting rod 35 slides inside the air pipe 33, thereby injecting air into the lower mold 32.

[0065] Simultaneously, when the connecting rod 38 on the suction assembly 3 moves upward, the trapezoidal teeth 382 on the connecting rod 38 will drive the meshing toothed column 41 to rotate in the opposite direction. The rotation of the toothed column 41 will drive the toothed disc 42 to rotate in the opposite direction, and the toothed disc 42 will drive the meshing rack 45 to move upward. The rack 45 will drive the ring sleeve 44 to move upward. At the same time, the sliding rod 46 on the ring sleeve 44 will slide upward in the circular hole 325 on the annular groove 324. Due to the elastic potential energy of the compression spring 442 inside the sleeve 443 on the ring sleeve 44 and the elastic potential energy of the elastic ring 444, a clamping force will be applied to the workpiece after forging. During the upward movement of the upper mold 31, the ring sleeve 44 will be driven upward by the connecting rod 38, thereby driving the workpiece to move upward, realizing the rapid demolding of the workpiece.
