Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal accessory processing, and particularly relates to an automatic press and application thereof in metal accessory processing. BACKGROUND

[0002] In the processing of aerospace high-strength aluminum alloy forgings, aluminum alloy precision die forgings, high-speed rail shafts, body die forgings, marine diesel engine die forgings and automobile metal accessories, a press is needed to process the above metal accessories; in the prior art, the work of the press is to move the press plate and the die driven by the driving part to apply process force to the above metal accessories to realize the processing of aluminum alloy precision die forgings and the like.

[0003] However, in the prior art, although the related technology of the press has been mature, there are still some problems in actual use; in the process of moving the press plate and the die driven by the press, the existing press is usually of the upper pressing type, that is, the upper hydraulic column extends downward to drive the upper die to move downward, and the lower press plate and the die remain stationary; however, this mode causes rapid wear of the die in actual use, which is not conducive to prolonging the service life of the die and increases the cost of metal accessory processing.

[0004] In the use of the press, only the upper hydraulic column moves, and when the press works, the efficiency is generally pursued to be improved, so the upper die is pressed downward quickly, which is not conducive to dispersing the material between the upper die and the lower die; when processing in a complex die, although the aluminum alloy precision die forgings and the like are heated to a certain extent, the aluminum alloy precision die forgings and the like still have a certain hardness, so the material of the aluminum alloy precision die forgings and the like often cannot be dispersed and uniformized in a very short time, thereby causing the processed aluminum alloy precision die forgings and the like to have uneven thickness.

[0005] Although slow extrusion can achieve good dispersion effect of the aluminum alloy precision die forgings and the like, when slow extrusion is performed, only extrusion in the upward direction is performed, so the stress direction of the metal is fixed and the metal material cannot be well expanded to the surroundings, so there is still the problem of uneven dispersion of the metal, thereby increasing the probability of defects of the processed metal accessory. SUMMARY

[0006] The present application aims to provide an automatic press and application thereof in metal accessory processing, which solves the problems of rapid wear of the die, uneven distribution of the metal material during processing and high defect rate of the metal accessory after processing.

[0011] Preferably, a plurality of guide sleeves are fixedly arranged on the lower die, and a plurality of insertion rods corresponding to the guide sleeves and capable of being inserted into the corresponding guide sleeves are fixedly arranged on the upper die.

[0012] Preferably, the vibration assembly includes a guide member fixedly arranged on the lower die away from the upper hydraulic column, a rotating member rotatably arranged in the lower pressing plate, and a plurality of knocking members fixedly arranged on the rotating member and capable of contacting the guide member.

[0013] Preferably, a pull rope is wound around the knocking members, a fixed column is fixedly arranged on the press body, and a free end of the pull rope is fixedly connected to the fixed column.

[0014] Preferably, when the lower hydraulic column moves downward, the lower pressing plate moves downward, the rotating member moves downward synchronously, under the traction of the fixed column and the pull rope, the rotating member drives the knocking members to rotate, the knocking members knock the guide member to generate vibration, and the metal material is evenly distributed.

[0015] Preferably, a reset member is arranged between the rotating member and the lower pressing plate, when the rotating member moves toward the upper pressing plate, the reset member drives the rotating member to rotate in the opposite direction, and the pull rope is wound on the rotating member again.

[0016] Preferably, the press body is provided with a controller, a pressure sensor is arranged between the end of the guide away from the lower die and the lower pressing plate, the pressure sensor is electrically connected with the controller, a hydraulic oil tank is arranged in the press body, the upper hydraulic column and the lower hydraulic column are connected with the hydraulic oil tank through proportional valves and conveying pipelines, and the proportional valves and the hydraulic oil tank are electrically connected with the controller.

[0017] The metal accessory is processed by using the automatic press.

[0018] Compared with the prior art, the beneficial effects of the present application are:

[0019] 1. By controlling the hydraulic oil tank and the proportional valve through the controller, the proportion of the hydraulic oil delivered and extracted between the upper hydraulic column and the lower hydraulic column is different, so that the speed of the upper hydraulic column and the lower hydraulic column when moving downward and upward at the same time is different, so that when the upper die and the lower die process the metal accessory, the impact force between the upper die and the lower die during processing is reduced, thereby reducing the wear between them, thereby increasing the service life of the upper die and the lower die.

[0020] 2. Slow extrusion can prevent metal debris on the metal accessory from spreading around, prevent metal particles from scattering to the surrounding environment, and pose a threat to the health and safety of workers.

[0022] 4. The rotating member, the knocking member and the pull rope can better make the guide drive the upper die and the lower die to vibrate, thereby cooperating with the synchronous differential movement of the upper hydraulic column and the lower hydraulic column, and accelerating the diffusion efficiency of the metal material while the upper die and the lower die vibrate.

[0023] 5. The differential synchronous movement of the upper hydraulic column and the lower hydraulic column can provide sufficient diffusion time for the metal material, so that the metal material is more evenly dispersed when processed by the automatic press, the probability of defects is reduced, and the yield is improved.

[0024] 6. The insertion rod and the guide sleeve can move in the guide sleeve when the distance between the upper die and the lower die increases or decreases, i.e. when the upper die and the lower die move relatively or away from each other, thereby playing a good guiding role and preventing the upper die and the lower die from moving away from each other, which can cause the processing of aluminum alloy precision die forgings and other metal accessories to fail, thereby increasing the probability of defective products.

[0025] 7. Through the set screw, limit block and limit groove, the upper die and the lower die can be limited, the slip of the die during working is prevented, and the replacement and maintenance of the die are facilitated. BRIEF DESCRIPTION OF DRAWINGS

[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application. Embodiment 1

[0043] Although the related technology of the press machine is mature, there are still some problems in actual use. In the process of moving the press plate and the die driven by the press machine, the existing press machine is usually upper pressing type, that is, the upper hydraulic column extends downward to drive the upper die to move downward, and the lower press plate and die remain stationary. However, this way will cause rapid wear of the die in actual use, which is not conducive to prolonging the service life of the die and increasing the cost of metal part processing.

[0044] And in the process of using the press machine, since only the upper hydraulic column moves, and when the press machine works, the efficiency is generally pursued to be improved, so the upper die is pressed down quickly, which is not conducive to dispersing the material between the upper die and the lower die. When processing in a complex die, although the aluminum alloy precision die forging parts and the like are heated to a certain extent, the aluminum alloy precision die forging parts and the like still have a certain hardness, which causes the material of the aluminum alloy precision die forging parts and the like to often fail to disperse uniformly in a very short time, so that the processed aluminum alloy precision die forging parts and the like exist the situation of uneven thickness.

[0045] In order to solve the above technical problems, please refer to the drawings of the specification Figures 1 to 10The first embodiment of the present application provides an automatic press, which comprises an automatic press body 1, an upper hydraulic column 2 and a lower hydraulic column 3 fixedly arranged on the press body 1, an upper die 5 and a lower die 6 connected to the opposite ends of the upper hydraulic column 2 and the lower hydraulic column 3 through a connecting assembly 4, respectively, wherein when the upper hydraulic column 2 extends towards the lower hydraulic column 3, a certain pressure is generated on the lower die 6, then the lower hydraulic column 3 shrinks away from the upper hydraulic column 2, and the shrinking speed of the lower hydraulic column 3 is less than the extending speed of the upper hydraulic column 2, so as to prevent the upper die 5 and the lower die 6 from being worn too fast, the connecting assembly 4 connected to the lower hydraulic column 3 is internally provided with a vibration assembly 7, the vibration assembly 7 is used for vibrating the connecting assembly 4, so that the metal material to be processed is evenly distributed between the upper die 5 and the lower die 6, the connecting assembly 4 comprises 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 on the upper hydraulic column 2 close to one end of the lower hydraulic column 3, the lower pressing plate 402 is arranged on the lower hydraulic column 3 close to one end of the upper hydraulic column 2, the opposite ends of the upper pressing plate 401 and the lower pressing plate 402 are detachably connected with the upper die 5 and the lower die 6, respectively, the vibration assembly 7 comprises a guide piece 701 fixedly arranged on the lower die 6 away from one end of the upper hydraulic column 2, the press body 1 is provided with a controller 8, a pressure sensor 9 is arranged between the end of the guide piece 701 away from the lower die 6 and the lower pressing plate 402, the pressure sensor 9 is electrically connected with the controller 8, the press body 1 is internally provided with a hydraulic oil tank 10, the upper hydraulic column 2 and the lower hydraulic column 3 are connected with the hydraulic oil tank 10 through proportional valves 11 and conveying pipelines, the connecting pipelines are not shown in the figure, the proportional valves 11 and the hydraulic oil tank 10 are electrically connected with the controller 8.

[0046] In 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 pipelines and the corresponding proportional valves 11, the connection mode of the controller 8 and the hydraulic oil tank 10 is the prior art, which is not described in detail here, and the connection between the upper hydraulic column 2 and the lower hydraulic column 3 through the connecting pipelines and the proportional valves 11 is the prior art, which is not described in detail here, so as to make the upper hydraulic column 2 shrink, make the upper hydraulic column 2 drive the upper pressing plate 401 and the like to move upwards, make the upper pressing plate 401 drive the upper die 5 to move upwards through the limiting block 405 and the limiting groove 403, so as to place the metal fittings between the upper die 5 and the lower die 6, and facilitate the processing of the metal fittings.

[0047] The placement of the metal fittings can be driven by the existing transmission device, which is the prior art and will not be described in detail. When the metal fittings are driven onto the lower die 6, the visual sensor on the upper platen 401 detects. The visual sensor is not shown in the figure, and the visual sensor is electrically connected with the controller 8. After the metal fittings reach the designated position, the controller 8 starts the hydraulic oil tank 10 to deliver hydraulic oil into the upper hydraulic column 2 through the connecting pipeline and the proportional valve 11, so that the upper hydraulic column 2 extends downward, thereby driving the upper die 5 to move downward through the connecting assembly 4 on the upper hydraulic column 2, and processing the metal fittings.

[0048] After the upper hydraulic column 2 extends to a certain length, the upper hydraulic column 2 starts to apply pressure to the lower platen 402 through the upper platen 401 and the metal fittings. When the applied pressure reaches a certain degree, the pressure sensor 9 detects the 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 column 3 through the connecting pipeline and the proportional valve 11, so that the lower hydraulic column 3 starts to contract, and the proportion of delivery and extraction is controlled by the proportional valve 11, so that the extension speed of the upper hydraulic column 2 is greater than the contraction speed of the lower hydraulic column 3, thereby achieving good buffering effect, realizing uniform pressure distribution, reducing damage or destruction of the mold surface, improving the processing quality and surface of the parts, reducing vibration or noise caused by impact force, providing higher processing flexibility, not only giving the metal material time to expand outward, but also preventing metal debris caused by rapid forging from spreading around, preventing metal particles from scattering to the surrounding environment, and threatening the health and safety of personnel.

[0049] While the upper hydraulic column 2 drives the upper die 5 to move downward, the lower hydraulic column 3 starts to drive the lower die 6 to move downward, and the extension speed of the upper hydraulic column 2 is greater than the contraction speed of the lower hydraulic column 3, so that the metal material is slowly forged, and the pressure that can be applied by the upper hydraulic column 2 and the lower hydraulic column 3 fully meets the processing needs. After the lower hydraulic column 3 is extended to the limit position, the metal material between the upper hydraulic column 2 and the lower hydraulic column 3 is processed, and then the controller 8 controls the hydraulic oil tank 10 to extract the hydraulic oil in the upper hydraulic column 2, while the hydraulic oil tank 10 delivers hydraulic oil into the lower hydraulic column 3, and the proportion of delivery can make the upper hydraulic column 2 contract faster and the lower hydraulic column 3 extend slower, so that the distance between the upper platen 401 and the lower platen 402 gradually increases, facilitating the transfer of the processed metal fittings and the delivery of the metal fittings to be processed.

[0050] The controller 8 controls 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 proportions, so that the extension and contraction speeds of the upper hydraulic column 2 and the lower hydraulic column 3 are different when they move downward and upward at the same time, thereby reducing the impact force between the upper die 5 and the lower die 6 during processing, reducing the wear between them, increasing the service life of the upper die 5 and the lower die 6, and preventing metal debris from spreading around during slow extrusion, preventing metal particles from scattering to the surrounding environment, threatening the health and safety of workers, and delaying the movement of the material during slow extrusion, providing enough time for the material to move, preventing uneven distribution of the material due to poor material flow when the shape to be processed is complex, and allowing the metal material to be better stretched between the upper die 5 and the lower die 6 by changing the movement speed of the upper die 5 and the lower die 6 and extending the processing time of the upper die 5 and the lower die 6, thereby making the metal material more evenly distributed. Embodiment 2

[0051] Although slow extrusion can achieve good dispersion effect on aluminum alloy precision die forgings and other materials, slow extrusion only allows extrusion in the upward direction, which makes the metal force direction fixed and unable to make the metal material better spread around, so there is still a situation that the metal is not evenly dispersed, which increases the probability of defects in the processed metal fittings.

[0052] To solve the above technical problems, on the basis of the above embodiment, referring to the drawings of the specification Figures 1 to 10 It can be seen that the technical scheme adopted includes a vibration assembly 7, which includes a guide piece 701 fixedly arranged on the lower die 6 away from the upper hydraulic column 2, a rotating piece 702 rotatably arranged in the lower pressing plate 402, a plurality of knocking pieces 703 fixedly arranged on the rotating piece 702 and capable of contacting the guide piece 701, a pull rope 704 wound on the knocking piece 703, a fixed column 705 fixedly arranged on the press body 1, and a free end of the pull rope 704 fixedly connected with the fixed column 705. When the lower hydraulic column 3 moves downward, the lower pressing plate 402 moves downward, the rotating piece 702 moves downward synchronously, and under the traction of the fixed column 705 and the pull rope 704, the rotating piece 702 drives the knocking piece 703 to rotate, so that the knocking piece 703 knocks and vibrates the guide piece 701, making the metal material evenly distributed. The rotating piece 702 and the lower pressing plate 402 are provided with a reset piece 706, which drives the rotating piece 702 to rotate in the opposite direction when the rotating piece 702 moves in the direction of the upper pressing plate 401, so that the pull rope 704 is wound on the rotating piece 702 again.

[0053] In specific use, when the controller 8 controls the hydraulic oil tank 10 to drive the upper hydraulic column 2 to generate a certain degree of extrusion force on the lower die 6, the pressure sensor 9 starts to send a signal to the controller 8, so that the hydraulic oil tank 10 draws the hydraulic oil in the lower hydraulic column 3 through the connecting pipeline and the proportional valve 11, so that the lower hydraulic column 3 starts to shrink. At the same time that the lower hydraulic column 3 shrinks, the lower pressing plate 402 starts to drive the guide 701 to move downward, and the guide 701 starts to drive the rotating piece 702 to move downward, so that the rotating piece 702 drives the pull rope 704 and the knocking piece 703 to move downward, and the fixed end of the pull rope 704 away from the fixed end of the rotating piece 702.

[0054] Since the pull rope 704 is wound on the rotating piece 702, when the rotating piece 702 moves downward, the rotating piece 702 drives the knocking piece 703 to rotate, and the reset piece 706 is retracted, so that the knocking piece 703 knocks the guide 701, thereby causing the guide 701 to vibrate, and the vibration is transmitted to the lower pressing plate 402 and the lower die 6 through the guide 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, so that the upper die 5 and the lower die 6 vibrate at the same time, thereby causing the metal material to rapidly spread and distribute more uniformly between the upper die 5 and the lower die 6, and achieving a better effect of uniformly distributing the metal material.

[0055] The vibration of the upper die 5 and the lower die 6 is matched with the same direction 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, and at the same time, increases the vibration when the upper pressing die and the lower pressing die move downward at the same time, so that the upper die 5 and the lower die 6 can produce vibration in the same direction and at the same frequency, so as to eliminate the stress inside the aluminum alloy precision die forging or other metal workpieces, eliminate the stress influence inside the workpiece after forming, and prevent cracking or cracking.

[0056] At the same time of vibration, the flow of aluminum alloy material can be more uniform (the periodic stress provided by the plastic deformation vibration of dislocation motion promotes the dislocation motion inside the aluminum alloy. The dislocation motion is the main mechanism of material plastic deformation. This dynamic load makes the dislocation more easily slip and climb, thereby reducing the yield strength of the material and reducing the energy required for deformation), and the vibration will cause the metal material to have a grain boundary lubrication effect. The vibration energy will weaken the bonding force between the grain boundaries, so that the grains are more easily relative to slip during the deformation process, reducing the flow resistance caused by grain boundary friction. After the machining is completed, during the upward movement of the upper hydraulic column 2 and the lower hydraulic column 3, the rotating piece 702 starts to move upward under the action of the reset piece 706, and the rotating piece 702 rotates in the opposite direction, so that the pull rope 704 is wound on the rotating piece 702 again.

[0057] Through the setting of the rotatable rotating piece 702, the knocking piece 703 and the pull rope 704, the guide piece 701 can better drive the upper die 5 and the lower die 6 to vibrate, thereby cooperating with the synchronous differential speed movement of the upper hydraulic column 2 and the lower hydraulic column 3. When the upper die 5 and the lower die 6 vibrate to accelerate the diffusion efficiency of the metal material, the differential speed and same direction movement of the upper hydraulic column 2 and the lower hydraulic column 3 can provide sufficient diffusion time for the metal material, so that the metal material is more evenly dispersed when processed by the automatic press, the probability of defect generation is reduced, and the yield is improved. Embodiment 3

[0058] When the aluminum alloy and other metal materials are processed by the automatic press, especially when the precision die forgings are processed, although vibrating the upper die 5 and the lower die 6 can make the material distribution more uniform and reduce the probability of defective product generation, in the actual processing process, since the synchronous vibration between the upper die 5 and the lower die 6 cannot be guaranteed, when the upper die 5 and the lower die 6 vibrate, the upper die 5 and the lower die 6 may deviate, which causes the aluminum alloy and other metal materials to deviate between the upper die 5 and the lower die 6 when processed into precision die forgings, resulting in the need for reprocessing of the metal material, reducing the production efficiency and increasing the probability of defective product generation.

[0059] To solve the above technical problems, on the basis of the above embodiment, referring to the drawings of the specification Figures 1 to 10 It can be seen that the technical scheme adopted includes the lower die 6, the lower die 6 is fixedly provided with a plurality of guide sleeves 601, the upper die 5 is fixedly provided with a plurality of insertion rods 602 corresponding to the guide sleeves 601 and capable of being inserted into the corresponding guide sleeves 601, the upper die 5 and the lower die 6 are both provided with a plurality of limiting grooves 403, the upper pressing plate 401 and the lower pressing plate 402 are respectively threadedly connected with a plurality of screw rods 404 corresponding to the limiting grooves 403, and each screw rod 404 is respectively rotatably provided with a limiting block 405 capable of being inserted into the corresponding limiting groove 403.

[0060] In specific use, when the upper die 5 and the lower die 6 move upward or downward, since the upper die 5 is fixedly provided with a plurality of insertion rods 602, the lower die 6 is fixedly provided with a plurality of guide sleeves 601 corresponding to the insertion rods 602, and the insertion rods 602 are all inserted into the corresponding guide sleeves 601 and can slide in the corresponding guide sleeves 601, therefore, when the upper die 5 and the lower die 6 relatively move, the insertion rods 602 first slide in the corresponding guide sleeves 601, guiding the movement of the upper die 5 and the lower die 6, so that when the distance between the upper die 5 and the lower die 6 increases or decreases, the insertion rods 602 slide in the guide sleeves 601, preventing the deviation between the upper die 5 and the lower die 6.

[0061] Meanwhile, the upper die 5 and the lower die 6 can be vibrated synchronously, when the metal material is processed into the metal fittings, the better clamping and fixing effect can be achieved, when the mechanical parts are vibrated synchronously, the vibration phases of the parts are consistent, the stress can be more uniform, the extra stress and impact force caused by the asynchronous vibration can be reduced, the service life of the mechanical parts is prolonged, and the maintenance cost and the equipment failure rate are reduced.

[0062] Meanwhile, the upper die 5 and the lower die 6 can be limited by the screw rod 404, the limiting block 405 and the limiting groove 403, the slip of the die during the work can be prevented, and the upper die 5 and the lower die 6 can be conveniently disassembled, when the disassembly is needed, the screw rod 404 is rotated, the screw rod 404 is no longer threadedly connected with the corresponding lower pressing plate 401 and upper pressing plate 402, then the limiting block 405 is taken out from the limiting groove 403, the upper die 5 and the lower die 6 are disassembled, and then the new die can be replaced.

[0063] Meanwhile, the upper die 5 and the lower die 6 can be limited by the screw rod 404, the limiting block 405 and the limiting groove 403, the slip of the die during the work can be prevented, and the upper die 5 and the lower die 6 can be conveniently disassembled, when the disassembly is needed, the screw rod 404 is rotated, the screw rod 404 is no longer threadedly connected with the corresponding lower pressing plate 401 and upper pressing plate 402, then the limiting block 405 is taken out from the limiting groove 403, the upper die 5 and the lower die 6 are disassembled, and then the new die can be replaced.
