Description

Technical Field

[0001] The present invention relates to the technical field of metal fitting processing, and particularly relates to an automatic press and its application in metal fitting processing. Background Art

[0002] In the processing of high-strength aluminum alloy forgings for aerospace, precision die forgings of aluminum alloy, shafts for high-speed rail, die forgings for car bodies, die forgings for marine diesel engines, and automotive metal fittings, a press is required to process the above-mentioned metal fittings. In the prior art, the operation of the press is that a driving component drives a pressure plate and a mold to move, applying a process force to the above-mentioned metal fittings to achieve the processing of precision die forgings of aluminum alloy, etc.

[0003] However, in the prior art, although the related technology of the press has been mature, there are still some problems in the actual use process. During the process of the press driving the pressure plate and the mold to move, the existing press is usually of the upper pressing type, that is, the upper hydraulic column extends downward to drive the upper pressing mold to move downward, while the lower pressure plate and the mold remain stationary. However, in the actual use process, this method will cause rapid wear of the mold, which is not conducive to extending the service life of the mold and increases the cost of metal fitting processing.

[0004] Moreover, during the use of the press, since only the upper hydraulic column moves, and when the press is working, generally the improvement of efficiency is pursued, so the upper mold presses down quickly, which is not conducive to the dispersion of the material between the upper pressing mold and the lower pressing mold. When processing in a complex mold, although the precision die forgings of aluminum alloy, etc. are heated to a certain extent, the precision die forgings of aluminum alloy, etc. still have a certain hardness, resulting in that the materials of the precision die forgings of aluminum alloy, etc. often cannot be dispersed evenly in a very short time, thus resulting in uneven thickness of the processed precision die forgings of aluminum alloy, etc.

[0005] Although slow extrusion can achieve a good dispersion effect on the dispersion of metal materials such as precision die forgings of aluminum alloy, etc., during slow extrusion, due to only extrusion in the upper pressing direction, the metal stress direction is relatively fixed, and the metal material cannot expand well around, so there is still a situation where the metal dispersion is not uniform enough, resulting in an increased probability of defects in the processed metal fittings. Summary of the Invention

[0006] The purpose of the present invention is to provide an automatic press and its application in metal fitting processing, which solves the problems of fast mold wear, uneven distribution of metal materials during processing, and high defect rate of metal fittings after processing.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions: An automatic press includes a press body, and further includes an upper hydraulic column and a lower hydraulic column arranged on the press body. The opposite ends of the upper hydraulic column and the lower hydraulic column are respectively connected with an upper die and a lower die through connecting components. When the upper hydraulic column extends towards the lower hydraulic column, after a certain pressure is generated on the lower die, the lower hydraulic column contracts in a direction away from the upper hydraulic column, and the contraction speed of the lower hydraulic column is less than the extension speed of the upper hydraulic column, which is used to prevent the upper die and the lower die from wearing too fast. A vibration component is arranged inside the connecting component connected to the lower hydraulic column, and the vibration component is used to vibrate the connecting component so that the processed metal material is evenly distributed between the upper die and the lower die.

[0008] Preferably, the connecting component includes an upper pressing plate fixedly arranged on the upper hydraulic column and a lower pressing plate fixedly arranged on the lower hydraulic column. The opposite ends of the upper pressing plate and the lower pressing plate are respectively detachably connected with the upper die and the lower die.

[0009] Preferably, a plurality of limiting grooves are formed on both the upper die and the lower die. A plurality of screws corresponding to the limiting grooves are respectively threadedly connected to the upper pressing plate and the lower pressing plate, and a limiting block capable of being inserted into the corresponding limiting groove is respectively rotatably arranged on each screw.

[0010] Preferably, a plurality of guide sleeves are fixedly arranged on the lower die, and a plurality of inserting rods corresponding to the guide sleeves and capable of being inserted into the corresponding guide sleeves are fixedly arranged on the upper die.

[0011] Preferably, the vibration component includes a guiding member fixedly arranged at one end of the lower die away from the upper hydraulic column. A rotating member is rotatably arranged inside the lower pressing plate, and a plurality of knocking members capable of contacting the guiding member are fixedly arranged on the rotating member.

[0012] Preferably, a pulling rope is wound around the knocking member, and a fixing column is fixedly arranged on the press body. The free end of the pulling rope is fixedly connected with the fixing column.

[0013] Preferably, when the lower hydraulic column moves downward, the lower pressing plate moves downward, and the rotating member moves downward synchronously. Under the pulling of the fixing column and the pulling rope, the rotating member drives the knocking member to rotate, so that the knocking member knocks on the guiding member to generate vibration, making the metal material evenly distributed.

[0014] Preferably, a reset member is arranged between the rotating member and the lower pressing plate. When the rotating member moves towards the upper pressing plate, the reset member drives the rotating member to rotate in the opposite direction, so that the pulling rope is wound around the rotating member again.

[0015] Preferably, a controller is provided on the press body. A pressure sensor is provided between the end of the guiding member away from the lower die and the lower pressing plate. The pressure sensor is electrically connected to the controller. A hydraulic oil tank is provided inside the press body. The upper hydraulic column and the lower hydraulic column are both connected to the hydraulic oil tank through proportional valves and delivery pipes. The proportional valves and the hydraulic oil tank are both electrically connected to the controller.

[0016] A metal fitting processed by an automatic press uses the automatic press to process the metal fitting.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By enabling the controller to control the hydraulic oil tank and the proportional valves, and controlling the different proportions of hydraulic oil delivered and extracted between the upper hydraulic column and the lower hydraulic column, the speeds of the upper hydraulic column and the lower hydraulic column moving downward and upward simultaneously are different. Thus, when the upper die and the lower die process the metal fitting, the impact force between the upper die and the lower die during processing is reduced, the wear between the two is reduced, and the service life of the upper die and the lower die is increased.

[0018] 2. By slow extrusion, it can prevent metal chips on the metal fitting from spreading around, prevent metal particles from scattering into the surrounding environment and threatening the health and safety of workers. During slow extrusion, it can play a certain delaying role, enabling the metal material to pass through the different moving speeds of the upper die and the lower die when being extruded by the upper die and the lower die.

[0019] 3. By extending the processing time of the upper die and the lower die, the metal material can be better extended between the upper die and the lower die, so that the metal material is evenly distributed.

[0020] 4. Through the provided rotatable rotating member, knocking member and pull rope, it can better make the guiding member drive the upper die and the lower die to vibrate, thus cooperating with the synchronous differential movement of the upper hydraulic column and the lower hydraulic column. While the vibration of the upper die and the lower die speeds up the diffusion efficiency of the metal material.

[0021] 5. It can provide sufficient diffusion time for the metal material through the differential co-directional movement of the upper hydraulic column and the lower hydraulic column. Thus, when the metal material is processed using the automatic press, it is more evenly dispersed, the generation probability of defects is reduced, and the yield rate is improved.

[0022] 6. Through the provided insertion rod and guiding sleeve, when the distance between the upper die and the lower die increases or decreases, that is, when the upper die and the lower die move relatively or away from each other, the insertion rod can move in the guiding sleeve, playing a good guiding role and preventing the upper die and the lower die from shifting, resulting in the failure of processing metal fittings such as aluminum alloy precision forging parts and increasing the probability of defective products.

[0023] 7. By setting the screw, the limit block and the limit groove, the upper die and the lower die can be restricted, preventing the die from slipping during operation, and at the same time facilitating the replacement and repair of the die. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present invention. Embodiment 1

[0037] Although the related technologies of the press are mature, there are still some problems in the actual use process. When the press drives the pressure plate and the mold to move, the existing press is usually of the upper pressing type, that is, the upper hydraulic column extends downward to drive the upper pressing mold to move downward, while the lower pressure plate and the mold remain stationary. However, in the actual use process, this method will cause rapid wear of the mold, which is not conducive to extending the service life of the mold and increases the cost of metal parts processing.

[0038] Moreover, during the use of the press, since only the upper hydraulic column moves, and when the press is working, generally the improvement of efficiency is pursued. Therefore, the upper mold presses down relatively fast, which is not conducive to the dispersion of the material between the upper pressing mold and the lower pressing mold. When processing in a complex mold, although the aluminum alloy precision forging parts, etc. are heated to a certain extent, the aluminum alloy precision forging parts, etc. still have a certain hardness, resulting in the fact that the materials of the aluminum alloy precision forging parts, etc. often cannot be evenly dispersed in a very short time, thus resulting in uneven thickness of the processed aluminum alloy precision forging parts, etc.

[0039] To solve the above technical problems, please refer to the Figures 1 to 10It can be seen that the first embodiment of the present invention provides an automatic press, including an automatic press, including a press body 1, and further including an upper hydraulic column 2 and a lower hydraulic column 3 fixedly arranged on the press body 1. The opposite ends of the upper hydraulic column 2 and the lower hydraulic column 3 are respectively connected with an upper die 5 and a lower die 6 through a connecting component 4. When the upper hydraulic column 2 extends towards the lower hydraulic column 3, after a certain pressure is generated on the lower die 6, the lower hydraulic column 3 contracts in the direction away from the upper hydraulic column 2, and the contraction speed of the lower hydraulic column 3 is less than the extension speed of the upper hydraulic column 2, so as to prevent the upper die 5 and the lower die 6 from wearing too fast. A vibration component 7 is arranged inside the connecting component 4 connected to the lower hydraulic column 3. The vibration component 7 is used to vibrate the connecting component 4, so that the processed metal material is evenly distributed between the upper die 5 and the lower die 6. The connecting component 4 includes an upper pressing plate 401 fixedly arranged on the upper hydraulic column 2 and a lower pressing plate 402 fixedly arranged on the lower hydraulic column 3. The upper pressing plate 401 is arranged at one end of the upper hydraulic column 2 close to the lower hydraulic column 3, and the lower pressing plate 402 is arranged at one end of the lower hydraulic column 3 close to the upper hydraulic column 2. The opposite ends of the upper pressing plate 401 and the lower pressing plate 402 are respectively detachably connected to the upper die 5 and the lower die 6. The vibration component 7 includes a guiding member 701 fixedly arranged at one end of the lower die 6 far from the upper hydraulic column 2. A controller 8 is arranged on the press body 1. A pressure sensor 9 is arranged between the end of the guiding member 701 far from the lower die 6 and the lower pressing plate 402. The pressure sensor 9 is electrically connected to the controller 8. A hydraulic oil tank 10 is arranged inside the press body 1. The upper hydraulic column 2 and the lower hydraulic column 3 are both connected to the hydraulic oil tank 10 through a proportional valve 11 and a conveying pipeline (the connecting pipeline is not shown in the figure). The proportional valve 11 and the hydraulic oil tank 10 are both electrically connected to the controller 8.

[0040] During specific use, first, the controller 8 controls the hydraulic oil tank 10 to extract the hydraulic oil in the upper hydraulic column 2 through the connecting pipeline and the corresponding proportional valve 11. The connection method between the controller 8 and the hydraulic oil tank 10 is the prior art and will not be described in detail here. The connecting pipeline is not shown in the figure, and the connection between the upper hydraulic column 2 and the lower hydraulic column 3 through the connecting pipeline and the proportional valve 11 is the prior art and will not be described in detail here. The upper hydraulic column 2 is contracted, so that the upper hydraulic column 2 drives the upper pressing plate 401 and the like to move upward. The upper pressing plate 401 drives the upper die 5 to move upward through the limiting block 405 and the limiting groove 403, so that metal fittings can be placed between the upper die 5 and the lower die 6, which is convenient for processing the metal fittings.

[0041] The placement of metal fittings can be driven by existing transmission equipment, which is prior art and will not be described in detail here. When the metal fittings are transmitted to the lower die 6, a vision sensor on the upper pressure plate 401 detects them. The vision sensor is not shown in the figure and is electrically connected to the controller 8. After the metal fittings reach the designated position, the controller 8 activates the hydraulic oil tank 10 to deliver hydraulic oil into the upper hydraulic cylinder 2 through a connecting pipe and a proportional valve 11, causing the upper hydraulic cylinder 2 to extend downward. Thereby, the upper die 5 is driven downward through the connecting assembly 4 thereon to process the metal fittings.

[0042] After the upper hydraulic cylinder 2 extends downward by a certain length, the upper hydraulic cylinder 2 begins to apply pressure to the lower pressure plate 402 through the upper pressure plate 401 and the metal fittings. When the applied pressure reaches a certain level, the pressure sensor 9 detects this pressure value and sends a signal to the controller 8. The controller 8 controls the hydraulic oil tank 10 to extract the hydraulic oil in the lower hydraulic cylinder 3 through the connecting pipe and the proportional valve 11, causing the lower hydraulic cylinder 3 to start contracting. And by controlling the ratio of the delivery and extraction of the proportional valve 11, the extension speed of the upper hydraulic cylinder 2 is made greater than the contraction speed of the lower hydraulic cylinder 3, thereby achieving a good buffering effect, enabling a uniform pressure distribution, reducing die surface damage or breakage, improving the machining quality and surface of the parts, reducing vibration or noise caused by impact force, providing higher machining flexibility, not only being able to give time for the metal material to extend outward, but also being able to prevent metal debris of the metal material from spreading around due to rapid forging, and preventing metal particles from scattering into the surrounding environment, posing a threat to the health and safety of personnel.

[0043] While the upper hydraulic cylinder 2 drives the upper die 5 downward, the lower hydraulic cylinder 3 begins to drive the lower die 6 downward, and the extension speed of the upper hydraulic cylinder 2 is greater than the contraction speed of the lower hydraulic cylinder 3 to slowly forge the metal material. And the pressure that the upper hydraulic cylinder 2 and the lower hydraulic cylinder 3 can apply fully meets the processing requirements. After the lower hydraulic cylinder 3 retracts and extends to the limit position, the metal material between the upper hydraulic cylinder 2 and the lower hydraulic cylinder 3 is processed. Then the controller 8 controls the hydraulic oil tank 10 to extract the hydraulic oil in the upper hydraulic cylinder 2, and at the same time, the hydraulic oil tank 10 delivers hydraulic oil into the lower hydraulic cylinder 3, and the delivery ratio can make the upper hydraulic cylinder 2 contract faster and the lower hydraulic cylinder 3 extend slower, so that the distance between the upper pressure plate 401 and the lower pressure plate 402 gradually increases, facilitating the transfer of the processed metal fittings and the conveyance of the metal fittings to be processed.

[0044] By making the controller 8 control the hydraulic oil tank 10 and the proportional valve 11 to deliver and extract hydraulic oil between the upper hydraulic column 2 and the lower hydraulic column 3 at different ratios, the extension and contraction speeds of the upper hydraulic column 2 and the lower hydraulic column 3 when moving downward and upward simultaneously are made different. When the upper die 5 and the lower die 6 process metal fittings, the impact force between the upper die 5 and the lower die 6 during processing is reduced, thereby reducing the wear between the two, increasing the service life of the upper die 5 and the lower die 6, and slow extrusion can prevent metal debris on the metal fittings from spreading to the surrounding area, preventing metal particles from scattering into the surrounding environment and posing a threat to the health and safety of workers. Moreover, during slow extrusion, it can play a certain delaying role, providing sufficient time for the movement of materials, preventing poor material flow effect and uneven material distribution when the shape to be processed is complex. When the metal material is extruded by the upper die 5 and the lower die 6, due to the different movement speeds of the upper die 5 and the lower die 6 and the extended processing time of the upper die 5 and the lower die 6, the metal material can be better extended between the upper die 5 and the lower die 6, making the metal material evenly distributed. Embodiment 2

[0045] Although slow extrusion can achieve a good dispersion effect on materials such as aluminum alloy precision die forgings, during slow extrusion, since only extrusion in the upward pressing direction is performed, the stress direction of the metal is relatively fixed, and the metal material cannot expand well to the surrounding area. Therefore, there is still a situation where the metal dispersion is not uniform enough, increasing the probability of defects in the processed metal fittings.

[0046] To solve the above technical problems, on the basis of the above embodiments, referring to the Figures 1 to 10 As can be seen, the technical solution adopted includes a vibration assembly 7. The vibration assembly 7 includes a guide member 701 fixedly arranged at one end of the lower die 6 away from the upper hydraulic column 2. A rotating member 702 is rotatably arranged in the lower pressing plate 402. A plurality of knocking members 703 that can contact the guide member 701 are fixedly arranged on the rotating member 702. A pulling rope 704 is wound around the knocking member 703. A fixed column 705 is fixedly arranged on the press body 1. The free end of the pulling rope 704 is fixedly connected to the fixed column 705. When the lower hydraulic column 3 moves downward, the lower pressing plate 402 moves downward, and the rotating member 702 moves downward synchronously. Under the pulling of the fixed column 705 and the pulling rope 704, the rotating member 702 drives the knocking member 703 to rotate, causing the knocking member 703 to knock on the guide member 701 to generate vibration, making the metal material evenly distributed. A reset member 706 is arranged between the rotating member 702 and the lower pressing plate 402. When the rotating member 702 moves in the direction of the upper pressing plate 401, the reset member 706 drives the rotating member 702 to rotate in the opposite direction, causing the pulling rope 704 to be wound around the rotating member 702 again.

[0047] During specific use, when the extrusion force generated by the hydraulic oil tank 10 driven by the controller 8 to drive the upper hydraulic column 2 to drive the upper die 5 against the lower die 6 reaches a certain level, the pressure sensor 9 starts to send signals to the controller 8, causing the hydraulic oil tank 10 to extract the hydraulic oil in the lower hydraulic column 3 through the connecting pipe and the proportional valve 11, making the lower hydraulic column 3 start to contract. While the lower hydraulic column 3 contracts, the lower platen 402 starts to drive the guide member 701 to move downward, the guide member 701 starts to drive the rotating member 702 to move downward, the rotating member 702 drives the pull rope 704 and the knocking member 703 to move downward, making the end of the pull rope 704 fixed to the rotating member 702 move away from the end of the pull rope 704 fixed to the fixed column 705.

[0048] Since the pull rope 704 is wound around the rotating member 702, when the rotating member 702 moves downward, it drives the knocking member 703 to rotate, the reset member 706 is contracted, and the knocking member 703 knocks the guide member 701, thereby causing the guide member 701 to vibrate. The vibration is transmitted to the lower platen 402 and the lower die 6 through the guide member 701. Since there is a certain pressure between the lower die 6 and the upper die 5 at this time, the vibration is transmitted to the upper die 5 through the metal material, causing the upper die 5 and the lower die 6 to vibrate simultaneously, so that the metal material diffuses rapidly and is distributed more evenly between the upper die 5 and the lower die 6, achieving a better effect of making the metal material distribution uniform.

[0049] Moreover, the vibration of the upper die 5 and the lower die 6 is coordinated with the co-directional movement of the upper die 5 and the lower die 6, which not only provides sufficient diffusion time, but also accelerates the diffusion efficiency of the metal material. At the same time, when the upper pressing die and the lower pressing die move downward simultaneously, vibration is increased, enabling the upper die 5 and the lower die 6 to generate co-directional and co-frequency vibration, thereby eliminating the internal stress in the aluminum alloy precision forging or other metal workpieces, being able to eliminate the influence of the internal stress in the workpiece after forming, and preventing cracking or fissuring.

[0050] During vibration, it can make the flow of the aluminum alloy material more uniform (the dislocation movement promotes plastic deformation. The periodic stress provided by the vibration will activate the dislocation movement inside the aluminum alloy. Dislocation movement is the main mechanism of material plastic deformation. This dynamic load makes dislocations easier to slip and climb, thereby reducing the yield strength of the material and the energy required for deformation). And the vibration will cause the grain boundary lubrication effect in the metal material. The vibration energy will weaken the bonding force between grain boundaries, making the grains more likely to slide relative to each other during the deformation process, reducing the hindrance of grain boundary friction to flow. After the processing is completed, during the upward movement of the upper hydraulic column 2 and the lower hydraulic column 3, since the rotating member 702 starts to move upward, under the action of the reset member 706, the rotating member 702 rotates in the opposite direction, making the pull rope 704 wind around the rotating member 702 again.

[0051] By means of the rotatable rotating member 702, the knocking member 703 and the pull rope 704 provided, the guiding member 701 can better drive the upper die 5 and the lower die 6 to vibrate, so as to cooperate with the synchronous differential movement of the upper hydraulic column 2 and the lower hydraulic column 3. While the vibration of the upper die 5 and the lower die 6 accelerates the diffusion efficiency of the metal material, the differential co-directional movement of the upper hydraulic column 2 and the lower hydraulic column 3 can provide sufficient diffusion time for the metal material, so that when the metal material is processed by an automatic press, it is dispersed more evenly, the generation probability of defects is reduced, and the yield rate is improved. Embodiment 3

[0052] When processing metal materials such as aluminum alloy by an automatic press, especially when processing into precision die forgings, although vibrating the upper die 5 and the lower die 6 can make the material distribution more uniform and reduce the generation probability of defective products, in the actual processing process, due to the inability to ensure the synchronous vibration between the upper die 5 and the lower die 6, when the upper die 5 and the lower die 6 are vibrated, it may cause the upper die 5 and the lower die 6 to shift during vibration, resulting in the upper die 5 and the lower die 6 shifting when processing metal materials such as aluminum alloy into precision die forgings, resulting in the need to reprocess the metal material, reducing the production efficiency while increasing the generation probability of defective products.

[0053] To solve the above technical problems, on the basis of the above embodiments, referring to the Figures 1 to 10 It can be obtained that the adopted technical solution includes a lower die 6, on which a plurality of guide sleeves 601 are fixedly arranged, and on the upper die 5, a plurality of inserting rods 602 corresponding to the guide sleeves 601 and capable of being inserted into the corresponding guide sleeves 601 are fixedly arranged. A plurality of limiting grooves 403 are respectively formed on the upper die 5 and the lower die 6, and a plurality of screw rods 404 corresponding to the limiting grooves 403 are respectively threadedly connected to the upper pressing plate 401 and the lower pressing plate 402. A limiting block 405 capable of being inserted into the corresponding limiting groove 403 is respectively rotatably arranged on each screw rod 404.

[0054] During specific use, when the upper die 5 and the lower die 6 move upward or downward, since a plurality of inserting rods 602 are fixedly arranged on the upper die 5, and a plurality of guide sleeves 601 corresponding to the inserting rods 602 one by one are fixedly arranged on the lower die 6, and the inserting rods 602 are all inserted into the corresponding guide sleeves 601 and can slide in the corresponding guide sleeves 601, when relative movement occurs between the upper die 5 and the lower die 6, the inserting rods 602 first slide in the corresponding guide sleeves 601, guiding the movement of the upper die 5 and the lower die 6. When the distance between the upper die 5 and the lower die 6 increases or decreases, the inserting rods 602 slide in the guide sleeves 601, preventing the situation of deviation between the upper die 5 and the lower die 6.

[0055] At the same time, it can make the upper die 5 and the lower die 6 vibrate synchronously. When processing metal materials into metal fittings, it can play a better clamping and fixing role. And when the mechanical components vibrate synchronously, the vibration phases of each component are consistent, which can make the force more uniform, reduce the additional stress and impact force caused by asynchronous vibration, extend the service life of the mechanical components, and reduce the maintenance cost and equipment failure rate.

[0056] At the same time, through the arranged screw rod 404, limit block 405 and limit groove 403, the upper die 5 and the lower die 6 can be restricted to prevent the die from slipping during operation. And it is convenient to disassemble the upper die 5 and the lower die 6. When disassembly is required, rotate the screw rod 404 to make the screw rod 404 no longer threadedly connected to the corresponding lower pressing plate 401 and upper pressing plate 402, then take out the limit block 405 from the limit groove 403, remove the upper die 5 and the lower die 6, and then replace them with new dies.

[0057] Through the arranged insertion rod 602 and guide sleeve 601, when the distance between the upper die 5 and the lower die 6 increases or decreases, that is, when the upper die 5 and the lower die 6 move relatively or away from each other, the insertion rod 602 can move in the guide sleeve 601, playing a good guiding role to prevent the upper die 5 and the lower die 6 from shifting, resulting in the failure of processing metal fittings such as aluminum alloy precision forging parts and increasing the probability of defective products. At the same time, through the arranged screw rod 404, limit block 405 and limit groove 403, the upper die 5 and the lower die 6 can be restricted to prevent the die from slipping during operation, and at the same time, it is convenient for die replacement and maintenance. Embodiment 4

[0058] On the basis of the above embodiments, this embodiment also provides an application of an automatic press in the processing of metal fittings, including using the automatic press to process metal fittings.

[0059] In specific applications, metal materials such as aluminum alloy are conveyed between the upper die 5 and the lower die 6 through a conveying device. Then, a vision sensor is used to detect whether the position of the metal materials such as aluminum alloy is correct. After confirmation, a signal is sent to the controller 8. Subsequently, the upper hydraulic column 2 drives the upper pressing plate 401 and the upper die 5 to move downward to extrude the metal materials such as aluminum alloy. When a certain pressure is reached, the pressure sensor 9 sends a signal to the controller 8 to cause the lower hydraulic column 3 to contract. The contraction speed of the lower hydraulic column 3 is less than the extension speed of the upper hydraulic column 2 to process the metal materials such as aluminum alloy. During the contraction process of the lower hydraulic column 3, the knocking member 703 knocks on the guiding member 701 to cause the upper die 5 and the lower die 6 to vibrate. At the same time, the insertion rod 602 and the guiding sleeve 601 can guide the movement of the upper die 5 and the lower die 6. When the lower hydraulic column 3 moves downward to the limit position, the processing of the metal materials such as aluminum alloy is completed, and corresponding precision die forgings of aluminum alloy or other metal fittings are processed.

[0060] As mentioned above, the above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
