Description

Technical Field

[0001] The present invention relates to the technical field of die forging processing of forgings, in particular to die forging forming processing equipment for aviation aluminum alloy forgings. Background Art

[0002] Aviation aluminum alloy forgings are core aviation structural parts made from high-strength aluminum alloys through forging processes such as free forging and die forging. The high temperature and pressure during the forging process can effectively eliminate defects such as pores and looseness inside the material, promote grain refinement and arrangement along the direction of force, thus having excellent mechanical properties. Not only is the strength comparable to that of some steels, achieving significant lightweighting, it also has excellent fatigue resistance, corrosion resistance and good processing formability.

[0003] Aviation aluminum alloy forgings are mainly produced through die forging processing. During the specific processing, the aluminum alloy billet is first heated to the plastic temperature and then placed in the forging mold cavity of the die forging machine. The die forging machine applies pressure through components such as the slider, forcing the billet to undergo plastic deformation under the constraints of the cavity, filling the cavity to obtain a predetermined shape. At the same time, the pressure refines the material grains and eliminates defects, ultimately forming high-performance forgings.

[0004] After the forging is formed, it is difficult to remove it from the cavity. Usually, a ejector is used to push the forging out of the cavity, or a tool is used to lift the forging out from the outside. Since the temperature of the forging is high at the initial stage of forming and it is still in the plastic stage, the surface is relatively fragile. If the forging is immediately removed using a ejector or a tool, it is easy to cause scratches, indentations and other defects on the forging surface, and even cause shape distortion and reduced dimensional accuracy. Furthermore, in the existing technology, it is usually chosen to wait for the forging to cool for a period of time before removing it. The cooling time prolongs the forging processing cycle, resulting in low work continuity, thereby reducing the production efficiency of aviation aluminum alloy forgings. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects.

[0018] Several shaped dies are evenly spaced and embedded in the outer wall of the cylinder. A drive mechanism rotates the cylinder so that each shaped die is aligned with the forging die in sequence, achieving multi-station alternating operation. While the top shaped die and the forging die are completing the forging, the forgings in the other shaped dies can be cooled simultaneously. This solves the problem of traditional single-station cooling, which leads to extended processing cycles, and significantly improves production continuity and efficiency.

[0019] The circular float and the inner wall of the circular cavity form a crescent-shaped clamping cavity. The cooling area formed by the cooling medium in the clamping cavity covers the area except the topmost shaping die. This not only ensures the effective cooling of the forgings in non-forging stations, but also avoids the plastic deformation performance of the forging blank in the topmost shaping die being affected by excessive cooling, thereby reducing the forming defects of the forgings caused by improper cooling.

[0020] The amount of cooling medium in the crescent-shaped cavity increases as the height decreases, causing the cooling of the forging inside the die to intensify in a step-by-step manner. This gradient cooling avoids excessive internal stress in the forging caused by rapid cooling, reduces defects such as cracking and deformation, and helps ensure the uniformity and stability of the forging's mechanical properties.

[0021] The linkage mechanism drives the cylinder to rise and fall periodically. When it descends to the extreme position, the cylinder abuts the arc-shaped opening of the support seat. At this time, the top forming die corresponds to the forging die, and the bottom forming die corresponds to the material-retrieving mechanism. The support of the support seat enhances the structural stability during forging. The rising action avoids excessive wear on the cylinder and the support seat during rotation and adjustment, extending the life of the equipment while ensuring precise docking of the process.

DETAILED DESCRIPTION

[0034] The embodiments of the present invention are described below with reference to the accompanying drawings.

[0035] Example 1

[0036] See also Figures 1-11 The present invention provides a die forging processing equipment for aviation aluminum alloy forgings, including a workbench 1, a forging die 5 is installed above the workbench 1 through a pressing mechanism 6, specifically, combined with Figure 11 The pressing mechanism 6 includes a top frame 62, a hydraulic cylinder 63 and a lifting platform 64. Vertical columns 61 are fixed at the four corners above the workbench 1. Top frames 62 are fixed to the tops of the four columns 61. The lifting platform 64 is slidably mounted on the four columns 61, that is, the lifting platform 64 has the ability to move up and down along the columns 61. The forging die 5 is fixed on the lower surface of the lifting platform 64. The hydraulic cylinder 63 is vertically fixed on the top of the top frame 62, and the telescopic end extends through to the bottom of the top frame 62 and is fixedly connected to the lifting platform 64. The telescopic work of the hydraulic cylinder 63 can drive the lifting platform 64 and the forging die 5 downward and upward, thereby providing drive for the downward forging and upward resetting of the forging die 5.

[0037] The die forging processing equipment also includes a driving mechanism 2, a cylindrical body 3 and a shaping die 4. The cylindrical body 3 is mounted above the workbench 1 by the driving mechanism 2 and extends along the length direction of the workbench 1. A plurality of shaping dies 4 are embedded on the outer peripheral wall of the cylindrical body 3 at equal intervals around its axis. The cavity openings of the shaping dies 4 face outward along the radial direction of the cylindrical body 3. The driving mechanism 2 is used to drive the cylindrical body 3 to rotate around its own axis. During the rotation of the cylindrical body 3, the cylindrical body 3 drives each shaping die 4 to correspond to the position of the forging die 5 in sequence.

[0038] The equipment provided in this application arranges multiple shaping dies 4 on a circumferential path so that during the rotation of the cylinder 3, each shaping die 4 is aligned with the forging die 5 in turn to complete the forging process. Furthermore, when one of the shaping dies 4 corresponds to the forging die 5, the remaining shaping dies 4 do not participate in the forging process, so that the forgings after forging have sufficient cooling time, and the forging operation can be carried out continuously, thereby improving production efficiency.

[0039] Among them, the cylindrical body 3 has a circular cavity 31, and a circular float 32 is horizontally arranged in the circular cavity 31. The circular cavity 31 and the axis of the circular cavity 31 remain parallel, and the diameter of the circular float 32 is smaller than the inner diameter of the circular cavity 31, ensuring that there is additional space in the circular cavity 31 for the circular float 32 to move, so that the circular float 32 can move dynamically due to buoyancy during the rotation of the cylindrical body 3. In addition, the two ends of the circular float 32 are movably fitted with the inner walls of the two sides of the circular cavity 31, so as to avoid the circular float 32 from arbitrarily deflecting and misaligning in the circular cavity 31.

[0040] like Figure 2As shown, an inlet system 33 is provided on one side of the cylinder 3, and a discharge system 34 is provided on the other side. The inlet system 33 is used to introduce the cooling medium into the circular cavity 31, and the discharge system 34 is used to discharge the cooling medium after heat exchange in the circular cavity 31, so as to realize circulating water cooling.

[0041] When there is liquid cooling medium in the circular cavity 31, the cooling medium will always float at the top of the circular cavity 31 due to gravity, the property of liquid flowing downwards, and the buoyancy of the liquid on the circular float 32, thereby forming a crescent-shaped cavity between the outer wall of the circular float 32 and the inner wall of the circular cavity 31. Figure 3 and Figure 5 As shown, the cooling area 01 formed when the cooling medium flows in the clamp cavity covers the shaping mold 4 except the top, that is, the cooling medium in the cooling area 01 can cool the shaping mold 4 except the top.

[0042] Through the above-mentioned cooling mechanism, the cooling area is mainly concentrated in the non-forging area inside the cylinder 3, so that the forging can receive sufficient cooling when moving downstream after forming. The topmost forming die 4 serves as a forging station, away from the cooling medium, which can avoid excessive cooling of the workpiece when it is not forming and affecting the forming quality.

[0043] A specific cooling zone is formed by arranging a circular float 32 in the circular cavity 31. During the rotation of the cylindrical body 3, the circular float 32 can always float to the top of the circular cavity 31, so that the above-mentioned cooling zone always remains consistent, ensuring the consistency of cooling of each forging. On the other hand, the circular float 32 occupies a certain space in the circular cavity 31 to save the use of cooling medium in the circular cavity 31, killing two birds with one stone.

[0044] In addition, the amount of cooling medium on both sides of the crescent-shaped cavity gradually increases as the height decreases. Different amounts of cooling medium have different cooling effects on the forgings, ensuring that during the rotation of the cylinder 3, the cooling degree of the forgings changes in a gradually intensified step-by-step manner, avoiding excessively rapid cooling of the forgings and causing defects such as large internal stress, cracking, deformation or uneven hardness, thereby further improving the forming quality of the forgings.

[0045] like Figure 7As shown, the workbench 1 has a hollow cavity, and a pair of guide cylinders 211 are fixed on the top of the workbench 1. The bottom ends of the two guide cylinders 211 extend through the hollow cavity, and vertical support columns 212 are slidably installed in the two guide cylinders 211. The tops of the two support columns 212 are rotatably installed with shafts 301 through bearing seats 21. The cylindrical body 3 is fixed between the two shafts 301, and the cylindrical body 3 and the two shafts 301 are arranged coaxially. Such a layout enables the cylindrical body 3 to have both the ability to lift and lower, and the ability to rotate, and the sliding cooperation between the support columns 212 and the guide cylinders 211 plays a role of limiting and guiding the cylindrical body 3 in the vertical direction.

[0046] like Figure 8 As shown, the driving mechanism 2 includes a driving motor 23, a connecting shaft 24, a vertical frame 25 and a synchronous belt 26. The driving motor 23 is fixed to the workbench 1 through a mounting seat 22, and a pulley A231 is fixed on the output shaft. The connecting shaft 24 is transmission-connected to the end of the shaft rod 301 on the same side, and a pulley B241 is fixed on the connecting shaft 24. The vertical frame 25 is vertically fixed to the workbench 1, and a guide rod 251 that can slide back and forth is slidingly installed at its end. A U-shaped frame 252 is fixed at one end of the guide rod 251, and an end plate 27 is fixed at the other end. A pulley C253 is rotatably installed on the U-shaped frame 252. The synchronous belt 26 is transmission-mounted on the pulley A231, the pulley B241 and the pulley C253. A restraining spring 28 is sleeved on the guide rod 251, and one end of the restraining spring 28 is fixed to the vertical frame 25, and the other end is fixed to the end plate 27.

[0047] The driving motor 23 can drive the pulley A231 to rotate. Under the transmission cooperation of the synchronous belt 26 and the three sprockets, the connecting shaft 24 and the shaft rod 301 on the same side can be driven to rotate, thereby driving the cylinder 3 and the shaft rod 301 on the other side to rotate.

[0048] Among them, the cylinder 3 will be periodically raised and lowered during the working process. In order to adapt to the position changes of the cylinder 3 when it is raised and lowered, the present application provides a guide rod 251, an end plate 27 and a restraining spring 28. When the cylinder 3 rises, the synchronous belt 26 pulls the guide rod 251 and the pulley C253 to the front side. At this time, the restraining spring 28 is elastically compressed. When the cylinder 3 descends, the guide rod 251 and the pulley C253 are driven to move backward under the action of the elastic force of the restraining spring 28, so that the tension of the synchronous belt 26 can be adaptively adjusted with the raising and lowering of the cylinder 3 to ensure the stability of the driving mechanism 2 driving the cylinder 3 to rotate.

[0049] Example 2

[0050] See also Figure 3 The difference between this embodiment and embodiment 1 is that:

[0051] A flow channel 302 is provided in each of the two shafts 301 . Both flow channels 302 extend in the cylindrical body 3 and are connected to both sides of the circular cavity 31 , respectively. One side of the flow channel 302 is connected to the inlet system 33 , and the other side of the flow channel 302 is connected to the outlet system 34 .

[0052] Specifically, the inlet system 33 includes a sleeve 331 and an inlet pipe 332. The sleeve 331 is rotatably mounted on the end of the shaft 301 away from the drive motor 23. The inlet pipe 332 is fixedly connected to the side of the sleeve 331. One end of the inlet pipe 332 is connected to the flow channel 302 on the same side through the sleeve 331, and the other end is connected to the water outlet of the water cooling device (not shown in the figure). Figure 6 As shown, an inlet 321 is provided on the end face of the circular float 32 away from the drive motor 23, and there is always an overlapping area in which the inlet 321 and the flow channel 302 on the same side are connected. A number of inlet channels 322 are arranged in a circular array on the inner edge wall of the inlet 321, and the other end of each inlet channel 322 passes through the outer edge wall of the circular float 32, ensuring that no matter how the circular float 32 moves in the shaft 301, the cooling medium can enter the inlet 321 from the flow channel 302, and finally flow into the crescent-shaped clamp cavity through the inlet channel 322.

[0053] like Figure 4 As shown, the drainage system 34 includes a water collecting cover 341 and a drainage pipe 342. The water collecting cover 341 is rotatably mounted on the shaft 301 away from the side of the socket 331. One end of the drainage pipe 342 is connected to the water collecting cover 341, and the other end is connected to the return water end of the water cooling device. A plurality of flow holes 344 for connecting the flow channel 302 and the water collecting cover 341 are arranged in an annular array on the outer wall of the shaft 301 away from the side of the socket 331. The circular cavity 31 is away from A number of L-shaped extended drainage channels 343 are arranged in a circular array on the side end wall of the sleeve 331. The other end of each drainage channel 343 is connected to the flow channel 302 on the same side, and the ports of each drainage channel 343 communicating with the circular cavity 31 are all arranged near the inner edge wall of the circular cavity 31 to ensure that no matter how the circular float 32 moves in the shaft 301, the cooling medium can flow from the crescent-shaped clamping cavity through the drainage channel 343 into the flow channel 302 on the corresponding side.

[0054] The working principle of this embodiment is as follows: the cooling medium output by the water cooling equipment flows into the flow channel 302 on the same side through the connecting sleeve 331 and the inlet pipe 332 in sequence. Since the inlet port 321 and the flow channel 302 on this side always maintain an overlapping area connected, the medium enters the inlet channel 322 through the inlet port 321, and then flows into the crescent-shaped clamping cavity through the inlet channel 322, forming a cooling area 01 to cool other positions except the top forming mold 4. The cooling medium after heat exchange flows into the flow channel 302 on the same side through the discharge channel 343, and then flows into the water collecting cover 341 through the circulation hole 344, and finally flows back to the water cooling equipment through the discharge pipe 342, thereby realizing the circulation of the cooling medium.

[0055] Example 3

[0056] See also Figure 1 and Figure 8 The difference between this embodiment and embodiment 2 is that:

[0057] A linkage mechanism 8 is provided on the workbench 1 and the connecting shaft 24, which is used to link the cylinder 3 to periodic lifting and lowering during the rotation of the cylinder 3. Two support seats 7 are symmetrically fixed on the top of the workbench 1. The top of the two support seats 7 has an arc-shaped opening that matches the curvature of the outer wall of the cylinder 3. A material-removing mechanism 9 for removing the forging from the cavity of the forming mold 4 is provided at the top of the workbench 1 between the two support seats 7. During the periodic lifting of the cylinder 3, when the cylinder 3 drops to the extreme position each time, its outer wall abuts against the arc-shaped openings on the top of the two support seats 7. At the same time, the topmost forming mold 4 corresponds to the position of the forging mold 5, and the bottommost forming mold 4 corresponds to the position of the material-removing mechanism 9.

[0058] The linkage mechanism 8 links the cylindrical body 3 to perform periodic lifting and lowering during the rotation of the cylindrical body 3. Each time the cylindrical body 3 drops to the extreme position, its outer wall abuts against the arc-shaped openings at the top of the two support seats 7. At the same time, the topmost shaping die 4 corresponds to the forging die 5 for forging. The support seat 7 is used to provide effective support for the cylindrical body 3 and the shaping die 4 to ensure stability when the pressing mechanism 6 drives the forging die 5 to press down for forging. The bottommost shaping die 4 corresponds to the position of the material taking mechanism 9 to facilitate material taking.

[0059] In addition, when the cylinder 3 rotates to adjust the position of the forming mold 4, the cylinder 3 is moved upward through the linkage mechanism 8, so that the cylinder 3 is separated from the support seat 7, thereby avoiding excessive wear at the arc-shaped opening at the top of the cylinder 3 and the support seat 7. The periodic lifting and lowering of the cylinder 3 is coordinated with the above-mentioned position correspondence to ensure that the forging and material removal processes are carried out stably at the corresponding workstations.

[0060] Example 4

[0061] See also Figure 7 and Figure 8 The difference between this embodiment and embodiment 3 is that:

[0062] Specifically, the linkage mechanism 8 includes a half gear 81 and a gear ring 82. Two vertical racks are provided on the inner side of the ring 82. The half gear 81 is fixedly mounted on the connecting shaft 24. The gear ring 82 is vertically fixed to the workbench 1 through a bracket (not marked in the figure). The teeth on the half gear 81 are alternately meshed with the two racks on the inner surface of the gear ring 82. When the half gear 81 rotates one circle, it can mesh with the two racks on the inner side of the gear ring 82 in turn to complete an up and down movement. A reducer 83 is fixed to the side of the bearing seat 21 on one side through a support. One end of the reducer 83 is fixed to the shaft rod 301 on the same side, and the other end is fixedly connected to the connecting shaft 24. The connecting shaft 24 is coaxially arranged with the shaft rod 301 on the same side. When the half gear 81 rotates one circle, it can drive the cylindrical body 3 to rotate one-sixth of a circle under the speed transmission action of the reducer 83.

[0063] When the drive motor 23 starts working, its output shaft drives the pulley A231 to rotate. The pulley A231 drives the pulley B241 and the connecting shaft 24 to rotate synchronously through the transmission action of the synchronous belt 26. Since the half gear 81 is fixedly mounted on the connecting shaft 24, the connecting shaft 24 directly drives the half gear 81 to rotate together.

[0064] During the rotation of the half gear 81, the teeth on its edge will first engage with the rack on the inner surface of one side of the gear ring 82. Since the gear ring 82 is fixed on the workbench 1 and its position remains fixed, the engagement of the half gear 81 with the rack on one side of the gear ring 82 will generate an upward force, which is transmitted to the connecting shaft 24, the reducer 83, and the shaft 301 in sequence, and finally drives the cylinder 3 and the parts connected to it to move upward as a whole. During this process, the cylinder 3 gradually separates from the arc-shaped opening at the top of the support seat 7, realizing the upward action.

[0065] As the half gear 81 continues to rotate, when the teeth of the half gear 81 disengage from the rack on one side of the gear ring 82, it will continue to rotate until it engages with the rack on the inner surface of the other side of the gear ring 82. At this time, the engagement of the half gear 81 with the rack on the other side of the gear ring 82 will generate a downward force, which is also transmitted to the connecting shaft 24, the reducer 83, and the shaft 301 in sequence, driving the cylinder 3 and related components to move downward as a whole until the cylinder 3 drops to the extreme position, and its outer wall is tightly abutted against the arc-shaped opening at the top of the support seat 7, completing an up and down movement cycle.

[0066] At the same time, the rotation of the connecting shaft 24 is transmitted through the speed reducer 83. Since one end of the speed reducer 83 is fixedly connected to the connecting shaft 24 and the other end is fixedly connected to the shaft 301 on the same side, and the connecting shaft 24 and the shaft 301 are arranged coaxially, the speed reducer 83 reduces the rotation speed of the connecting shaft 24 and transmits it to the shaft 301. When the half gear 81 rotates one full revolution, the speed reduction of the speed reducer 83 causes the shaft 301 to rotate one-sixth of a full revolution.

[0067] During the process of the cylinder 3 rotating one-sixth of a circle, several forming dies 4 on its outer wall will rotate accordingly, so that the forming dies 4 originally in a non-top position move to the top, corresponding to the position of the forging die 5, and prepare for the next forging process; and the forming die 4 originally at the top moves to other positions and enters the cooling area 01 for cooling, realizing the sequential switching of the forming dies 4 and ensuring the continuous progress of the forging, cooling and other processes.

[0068] During the entire process, the meshing transmission of the half gear 81 and the gear ring 82 realizes the periodic lifting and lowering of the cylinder 3, and the variable speed transmission of the reducer 83 realizes the precise rotation angle control of the cylinder 3. The two work together to ensure that the cylinder 3 is stably supported by the support seat 7 during forging, and that the forming mold 4 can switch work stations in sequence according to a predetermined rhythm, thereby improving the continuity and stability of the equipment operation.

[0069] Example 5

[0070] See also Figure 7 and Figure 9 The difference between this embodiment and embodiment 4 is that:

[0071] Specifically, the material-taking mechanism 9 includes a cylinder 91, a power guide rail 92 and a vacuum suction cup 94. The cylinder 91 is vertically fixed on the top wall of the hollow cavity of the workbench 1, and the telescopic end extends through and extends above the workbench 1. The power guide rail 92 is installed on the telescopic end of the cylinder 91. A mounting plate 93 is fixed on the top of the movable seat 921 on the power guide rail 92. The power guide rail 92 is used to drive the mounting plate 93 to move back and forth. A pair of vacuum suction cups 94 are symmetrically installed on the top of the mounting plate 93. The power guide rail 92 installed at its end can be driven to rise and fall by the extension and contraction of the cylinder 91, so as to adjust the height of the power guide rail 92 and subsequent components to ensure that they are height-matched with the shaping mold 4 at the lowest position.

[0072] When the cylinder 3 drops to the limit position and the bottommost shaping mold 4 corresponds to the position of the material-removing mechanism 9, the power guide rail 92 drives the mounting plate 93 to move forward, and the cylinder 91 extends to push the power guide rail 92 upward, so that the two vacuum suction cups 94 are precisely aligned with the cavity opening of the shaping mold 4. After cooling, the forging shrinks and there is a movable gap between it and the inner wall of the cavity. Through the operation of the air distribution system, the two vacuum suction cups 94 are used to suck and grab the forging. Then, the cylinder 91 retracts to drive the forging to move downward. Subsequently, the power guide rail 92 works to transfer the forging to the unloading station on the rear side.

[0073] Among them, a robotic arm is installed at the unloading station, which can be used to grab the forgings and transfer them to the conveyor line so that the forgings can be transported to the downstream process.

[0074] like Figure 10 As shown, a side plate 95 extending forward and backward is fixed to the front surface of the mounting plate 93, and a pair of upward-facing air nozzles 96 are installed on the side plate 95. The two air nozzles 96 are connected to an air intake pipe 961 on the side close to each other. The ends of the two air intake pipes 961 are respectively connected to the two ends of a three-way joint 97. The third end of the three-way joint 97 is connected to an air pump (not shown in the figure) through an air guide pipe 98 to form a complete air injection passage. When the power guide rail 92 drives the vacuum suction cup 94 to reach the unloading station at the rear, the air nozzle 96 moves synchronously to the position corresponding to the lowest shaping mold 4.

[0075] When the power guide rail 92 drives the vacuum suction cup 94 to the rear unloading station, the air nozzle 96 moves synchronously with the mounting plate 93 to the position corresponding to the lowest shaping mold 4. At this time, the air pump supplies air to the air nozzle 96 through the air guide pipe 98, the three-way joint 97, and the air inlet pipe 961. The gas ejected upward by the air nozzle 96 can be used to clean the residual oxides and impurities in the cavity of the shaping mold 4 to prevent the residual impurities from affecting the next forging forming, and can also assist in cooling the cavity.

[0076] During the entire process, the lifting and lowering of the cylinder 91 ensures height adaptation, the forward and backward movement of the power guide rail 92 realizes the position switching between material collection and unloading, the vacuum suction cup 94 is responsible for grabbing the forgings, and the air jet from the air nozzle 96 assists in ensuring the processing quality from the two aspects of cleaning and cooling. All components work together to efficiently complete the entire process of removing the forgings from the cavity of the finalizing mold 4 and transferring them to the unloading station.

[0077] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field, so the present invention will no longer explain the control method and circuit connection in detail.

[0078] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
