Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of forging die forging processing, in particular to an aviation aluminum alloy forging die forging forming processing equipment. BACKGROUND

[0002] The aviation aluminum alloy forging is an aviation core structural part made of high-strength aluminum alloy as raw material through forging processes such as free forging and die forging. Through high-temperature and pressure in the forging process, it can effectively eliminate internal defects such as pores and porosity, promote grain refinement and arrange along the stress direction, thereby combining excellent mechanical properties. Not only can the strength be comparable to some steel materials, realizing significant lightweight, but also has excellent fatigue resistance, corrosion resistance and good processing formability.

[0003] The aviation aluminum alloy forging is mainly made by die forging machine. In specific processing, the aluminum alloy blank is heated to a plastic temperature and then placed in the die cavity of the die forging machine. The die forging machine applies pressure through the slide and other components to force the blank to deform plastically under the constraint of the cavity to fill the cavity and obtain the predetermined shape. At the same time, the pressure refines the material grains and eliminates defects, and finally forms a high-performance forging.

[0004] After the forging is formed, it is difficult to take out from the cavity. Usually, the forging is ejected from the cavity by a top piece, or the forging is pried out from the outside by a tool. Since the forging temperature is high at the beginning of forming and is still in the plastic stage, the surface is fragile. If the forging is immediately taken out by the top piece or the tool, it is easy to cause surface scratches, indentation and other defects of the forging, and even cause shape distortion and size precision decrease. Furthermore, in the prior art, the forging is usually taken out after cooling for a period of time. The cooling time prolongs the forging processing cycle, resulting in low work continuity and thus reducing the production efficiency of the aviation aluminum alloy forging. SUMMARY

DETAILED DESCRIPTION

[0034] The embodiments of the present application will be described below with reference to the accompanying drawings.

[0035] Example 1

[0036] Please refer to Figures 1-11 The application provides an aviation aluminum alloy forging die forging forming processing equipment, which comprises 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 comprises a top frame 62, a hydraulic cylinder 63 and a lifting platform 64, vertical columns 61 are respectively fixed at four top corners above the workbench 1, the top ends of the four vertical columns 61 are fixed with the top frame 62, the lifting platform 64 is slidingly sleeved on the four vertical columns 61, that is, the lifting platform 64 has the ability to move up and down along the vertical column 61, the forging die 5 is fixed to the lower surface of the lifting platform 64, the hydraulic cylinder 63 is vertically fixed to the top of the top frame 62, and the telescopic end extends to below the top frame 62 and is fixedly connected with the lifting platform 64, the lifting platform 64 and the forging die 5 can be driven to move downward and upward by the telescopic working of the hydraulic cylinder 63, thereby providing driving for the downward forging and upward resetting of the forging die 5.

[0037] The die forging forming processing equipment further comprises a driving mechanism 2, a cylindrical body 3 and a shaping die 4, the cylindrical body 3 is installed above the workbench 1 through 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 the axis of the cylindrical body 3, and the cavity opening of the shaping die 4 faces outward along the radial direction of the cylindrical body 3, wherein the driving mechanism 2 is used to drive the cylindrical body 3 to rotate around the axis thereof, and in the rotating process of the cylindrical body 3, the cylindrical body 3 drives each shaping die 4 to sequentially correspond to the position of the forging die 5;

[0038] The equipment provided by the application sets multiple shaping dies 4 on the circumferential path, so that each shaping die 4 sequentially corresponds to the position of the forging die 5 in the rotating process of the cylindrical body 3 to complete the forging processing, and when one shaping die 4 corresponds to the position of the forging die 5, the remaining shaping dies 4 do not participate in the forging processing, so that the forged workpiece has sufficient cooling time, and the forging operation can be continuously carried out, thereby improving the production efficiency.

[0039] The cylindrical body 3 has a circular cavity 31, a circular floating body 32 is horizontally arranged in the circular cavity 31, the axis of the circular cavity 31 and the circular cavity 31 are parallel, and the diameter of the circular floating body 32 is smaller than the inner diameter of the circular cavity 31, so that the circular cavity 31 has an additional space for the movement of the circular floating body 32, and the circular floating body 32 can dynamically move in the rotating process of the cylindrical body 3 due to the buoyancy, in addition, the two ends of the circular floating body 32 are respectively movably attached to the inner walls of the two sides of the circular cavity 31, so as to avoid the dislocation caused by the arbitrary deflection of the circular floating body 32 in the circular cavity 31.

[0040] As Figure 2As shown, the cylinder body 3 is provided with an inflow system 33 on one side and an outflow system 34 on the other side, the inflow system 33 is used to guide the cooling medium into the circular cavity 31, and the outflow system 34 is used to guide the cooling medium after heat exchange in the circular cavity 31 out, so as to realize the circulating water cooling.

[0041] When there is liquid cooling medium in the circular cavity 31, the circular floating body 32 always floats at the top of the circular cavity 31 due to the gravity and the characteristics of the liquid flowing to the low place, and the buoyancy of the liquid to the circular floating body 32, and then a crescent-shaped gap is formed between the outer wall of the circular floating body 32 and the inner wall of the circular cavity 31, as shown in Figure 3 and Figure 5 As shown, the cooling area 01 formed by the cooling medium flowing in the gap covers the shaped die 4 except the top part, that is, the cooling medium in the cooling area 01 can cool the position of the shaped die 4 except the top part.

[0042] Through the above cooling mechanism, the cooling position is mainly concentrated in the non-forging position of the cylinder body 3, and then the forged part can be fully cooled when moving downstream after being shaped, and the top part of the shaped die 4 as a forging position is far away from the cooling medium, which can avoid excessive cooling of the workpiece when not being shaped, thereby affecting the shaping quality.

[0043] By setting the circular floating body 32 in the circular cavity 31 to form a specific cooling area, and the circular floating body 32 always floats at the top of the circular cavity 31 during the rotation of the cylinder body 3, the above cooling area always remains consistent, which ensures the consistency of the cooling of each forged part. On the other hand, the circular floating body 32 occupies a certain space in the circular cavity 31, so as to save the use amount of the cooling medium in the circular cavity 31, which achieves two purposes at once.

[0044] In addition, the amount of cooling medium on both sides of the crescent-shaped gap gradually increases with the decrease of the height, and different amounts of cooling medium have different cooling effects on the forged part, which ensures that the cooling degree of the forged part gradually increases in a step-by-step manner during the rotation of the cylinder body 3, avoids excessive and rapid cooling of the forged part to produce large internal stress, cracking, deformation or uneven hardness, and further improves the shaping quality of the forged part.

[0045] As shown in 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, and the bottom ends of the two guide cylinders 211 extend into the hollow cavity, and a vertical support column 212 is slidably installed in the two guide cylinders 211, and a shaft rod 301 is rotatably installed on the top of the two support columns 212 through a bearing seat 21, and the cylindrical body 3 is fixed between the two shaft rods 301, and the cylindrical body 3 is coaxially arranged with the two shaft rods 301, so that the cylindrical body 3 has the ability to lift and rotate, and the support column 212 and the guide cylinder 211 are used to limit and guide the cylindrical body 3 in the vertical direction.

[0046] As shown in Figure 8 , 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 on the workbench 1 through a mounting seat 22, and a belt pulley A231 is fixed on the output shaft, the connecting shaft 24 is in transmission connection with the end of the shaft rod 301 on the same side, and a belt pulley B241 is fixed on the connecting shaft 24, the vertical frame 25 is vertically fixed on the workbench 1, and a front and rear sliding guide rod 251 is slidably installed on the end of the vertical frame 25, one end of the guide rod 251 is fixed with a U-shaped frame 252, and the other end is fixed with an end plate 27, the U-shaped frame 252 is rotatably installed with a belt pulley C253, the synchronous belt 26 is in transmission with the belt pulley A231, the belt pulley B241 and the belt pulley C253, and a restraining spring 28 is sleeved on the guide rod 251, one end of the restraining spring 28 is fixed with the vertical frame 25, and the other end is fixed with the end plate 27.

[0047] The driving motor 23 can drive the belt pulley A231 to rotate, and under the transmission 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, and then the cylindrical body 3 and the shaft rod 301 on the other side can be driven to rotate.

[0048] The cylindrical body 3 will be periodically adjusted in the working process, in order to adapt to the position change of the cylindrical body 3, the guide rod 251, the end plate 27 and the restraining spring 28 are arranged in the application, when the cylindrical body 3 rises, the synchronous belt 26 pulls the guide rod 251 and the belt pulley C253 to the front side, at this time the restraining spring 28 is elastically compressed, when the cylindrical body 3 descends, the guide rod 251 and the belt pulley C253 are driven to move back to the original position under the elastic force of the restraining spring 28, so that the tension of the synchronous belt 26 can be self-adaptively adjusted with the lifting of the cylindrical body 3, to ensure the stability of the driving mechanism 2 driving the cylindrical body 3 to rotate.

[0049] Example 2

[0050] Please refer to Figure 3 , the difference between this embodiment and example 1 is:

[0051] Both shafts 301 are provided with flow channels 302. Both flow channels 302 extend inside the cylindrical body 3 and are connected to both sides of the circular cavity 31 respectively. One flow channel 302 is connected to the inlet system 33, and the other 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 on the side 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 outlet of the water cooling equipment (not shown in the figure). Figure 6 As shown, the circular float 32 has an inlet 321 on the side of the end face away from the drive motor 23, and the inlet 321 and the flow channel 302 on the same side always have a connected overlapping area. Several inlet channels 322 are arranged in a ring array on the inner edge wall of the inlet 321, and the other end of each inlet channel 322 penetrates 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 clamping cavity through the inlet channel 322.

[0053] like Figure 4 As shown, the drainage system 34 includes a water collection cover 341 and a drainage pipe 342. The water collection cover 341 is rotatably mounted on a shaft 301 on the side away from the connecting sleeve 331. One end of the drainage pipe 342 is connected to the water collection cover 341, and the other end is connected to the return water end of the water-cooling equipment. Several flow holes 344 for connecting the flow channel 302 and the water collection cover 341 are arranged in a ring array on the outer wall of the shaft 301 on the side away from the connecting sleeve 331. The circular cavity 31 is away from the water collection cover 341. The side wall of the sleeve 331 is arranged in a ring array with several L-shaped extended drainage channels 343. The other end of each drainage channel 343 is connected to the flow channel 302 on the same side. The port of each drainage channel 343 that connects to the circular cavity 31 is located near the inner edge wall of the circular cavity 31. This ensures that no matter how the circular float 32 moves in the shaft 301, the cooling medium can flow from the crescent-shaped clamp cavity into the flow channel 302 on the corresponding side through the drainage channel 343.

[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 sleeve 331 and the inlet pipe 332 in sequence. Since the inlet 321 and the flow channel 302 on the same side always maintain a continuous overlapping area, the medium enters the inlet channel 322 through the inlet 321, and then flows into the crescent-shaped clamping cavity through the inlet channel 322 to form the cooling area 01 to cool other positions except the top shaping mold 4. After heat exchange, the cooling medium flows into the flow channel 302 on the same side through the outlet channel 343, and then flows into the water collection cover 341 through the flow hole 344. Finally, it flows back into the water cooling equipment through the outlet pipe 342, realizing the circulation of the cooling medium.

[0055] Example 3

[0056] Referring to Figure 1 and Figure 8 , the difference between this embodiment and example 2 is that:

[0057] The workbench 1 and the connecting shaft 24 are jointly provided with a linkage mechanism 8 for linking the periodic lifting of the cylindrical body 3 during the rotation of the cylindrical body 3. The workbench 1 is symmetrically fixed with two support seats 7 on the top, and the top of the two support seats 7 has an arc-shaped opening matching the curvature of the outer wall of the cylindrical body 3. The workbench 1 is provided with a material taking mechanism 9 between the two support seats 7 on the top for taking the forging from the cavity of the sizing die 4. During the periodic lifting of the cylindrical body 3, when the cylindrical body 3 drops to the limit position each time, the outer wall abuts against the arc-shaped opening at the top of the two support seats 7, and at the same time, the topmost sizing die 4 corresponds to the position of the forging press die 5, and the bottommost sizing die 4 corresponds to the position of the material taking mechanism 9.

[0058] The linkage mechanism 8 links the periodic lifting of the cylindrical body 3 during the rotation of the cylindrical body 3. When the cylindrical body 3 drops to the limit position each time, the outer wall abuts against the arc-shaped opening at the top of the two support seats 7, and at the same time, the topmost sizing die 4 corresponds to the position of the forging press die 5 for forging, and the bottommost sizing die 4 corresponds to the position of the material taking mechanism 9 for facilitating material taking. The support seats 7 provide effective support for the cylindrical body 3 and the sizing die 4 to ensure stability during the downward pressing of the forging press die 5 driven by the downward pressing mechanism 6.

[0059] In addition, when the cylindrical body 3 rotates to adjust the position of the sizing die 4, the linkage mechanism 8 links the upward movement of the cylindrical body 3, so that the cylindrical body 3 is separated from the support seats 7, thereby avoiding excessive wear of the cylindrical body 3 and the arc-shaped opening at the top of the support seats 7. The periodic lifting of the cylindrical body 3 ensures that the forging and material taking processes are stably performed at the corresponding stations.

[0060] Example 4

[0061] Referring to Figure 7 and Figure 8 , the difference between this embodiment and example 3 is that:

[0062] Specifically, the linkage mechanism 8 includes a half gear 81 and a gear ring 82, the annular inner side of the gear ring 82 is provided with two vertical toothed racks, the half gear 81 is fixedly sleeved on the connecting shaft 24, the gear ring 82 is vertically fixed on the workbench 1 through a support (not marked in the figure), the teeth on the half gear 81 are alternately engaged with the two toothed racks on the inner side surface of the gear ring 82, wherein the half gear 81 rotates one circle, can be sequentially engaged with the two toothed racks on the inner side of the gear ring 82 in turn, to complete one up-down movement, the side of one side bearing seat 21 is fixed with a speed reducer 83 through a support, one end of the speed reducer 83 is fixed with the shaft rod 301 on the same side, the other end is fixedly connected with the connecting shaft 24, the connecting shaft 24 is coaxially arranged with the shaft rod 301 on the same side, wherein the half gear 81 rotates one circle, under the speed reduction transmission of the speed reducer 83, can drive the cylinder body 3 to rotate one sixth of a circle.

[0063] When the driving motor 23 starts to work, the output shaft drives the pulley A231 to rotate, the pulley A231 drives the pulley B241 and the connecting shaft 24 to synchronously rotate through the transmission of the synchronous belt 26, since the half gear 81 is fixedly sleeved on the connecting shaft 24, the connecting shaft 24 directly drives the half gear 81 to rotate together.

[0064] In the rotating process of the half gear 81, the teeth on the edge thereof will first be engaged with the toothed rack on one side of the inner side surface of the gear ring 82, since the gear ring 82 is fixed on the workbench 1, the position remains fixed, the engagement of the half gear 81 with the toothed rack on one side of the gear ring 82 will generate an upward force, the force is sequentially transmitted to the connecting shaft 24, the speed reducer 83, the shaft rod 301, and finally drives the cylinder body 3 and the components connected thereto to move upward as a whole, in this process, the cylinder body 3 gradually separates from the arc-shaped opening at the top of the support seat 7, to realize the lifting action.

[0065] With the continuous rotation of the half gear 81, when the teeth of the half gear 81 are disengaged from the toothed rack on one side of the gear ring 82, the half gear 81 will continue to rotate to be engaged with the toothed rack on the other side of the inner side surface of the gear ring 82, at this time, the engagement of the half gear 81 with the toothed rack on the other side of the gear ring 82 will generate a downward force, the force is also sequentially transmitted to the connecting shaft 24, the speed reducer 83, the shaft rod 301, to drive the cylinder body 3 and the related components to move downward as a whole, until the cylinder body 3 is lowered to the limit position, the outer wall thereof is in close abutment with the arc-shaped opening at the top of the support seat 7, to complete one up-down movement cycle.

[0066] At the same time, the rotation of the connecting shaft 24 will be transmitted through the speed reducer 83, since one end of the speed reducer 83 is fixedly connected with the connecting shaft 24, the other end is fixedly connected with the shaft rod 301 on the same side, and the connecting shaft 24 is coaxially arranged with the shaft rod 301, the speed reducer 83 will reduce the rotating speed of the connecting shaft 24 and then transmit it to the shaft rod 301. When the half gear 81 rotates one circle, under the speed reduction of the speed reducer 83, the shaft rod 301 will drive the cylinder body 3 to rotate one sixth of a circle.

[0067] During the process of rotating the cylinder body 3 by one sixth of a circle, some of the shaping molds 4 on the outer circumferential wall of the cylinder body 3 will rotate with it, so that the shaping molds 4 originally in the non-top position are moved to the top position and correspond to the position of the forging die 5, ready for the next forging process; while the shaping molds 4 originally in the top position are moved to other positions and enter the cooling area 01 for cooling, realizing the sequential switching of the shaping molds 4 and ensuring the continuous performance of the forging, cooling and other processes.

[0068] During the whole process, the periodic lifting of the cylinder body 3 is realized by the meshing transmission of the half gear 81 and the gear ring 82, and the precise rotation angle control of the cylinder body 3 is realized by the variable speed transmission of the speed reducer 83. The two work together to ensure that the cylinder body 3 is stably supported by the supporting seat 7 during forging, and to ensure that the shaping molds 4 can be sequentially switched to the next position at the predetermined rhythm, improving the coherence and stability of the equipment operation.

[0069] Embodiment 5

[0070] Please refer to Figure 7 and Figure 9 The difference between this embodiment and embodiment 4 is:

[0071] Specifically, the taking mechanism 9 includes a cylinder 91, a power guide rail 92 and a vacuum chuck 94. The cylinder 91 is vertically fixed on the inner top wall of the workbench 1 and extends through the top of the workbench 1. The power guide rail 92 is installed on the extension end of the cylinder 91. The top of the moving seat 921 on the power guide rail 92 is fixed with a mounting plate 93. The power guide rail 92 is used to drive the mounting plate 93 to move forward and backward. A pair of vacuum chucks 94 is symmetrically installed on the top of the mounting plate 93. The height of the power guide rail 92 and the subsequent components can be adjusted by the extension and retraction of the cylinder 91 to ensure the height adaptation with the shaping molds 4 in the lowest position.

[0072] When the cylinder body 3 is lowered to the limit position and the shaping mold 4 at the bottom position corresponds to the position of the taking mechanism 9, the power guide rail 92 drives the mounting plate 93 to move forward. By the extension of the cylinder 91, the power guide rail 92 is pushed upwards, so that the two vacuum chucks 94 are accurately aligned with the cavity of the shaping mold 4. After cooling, the forging is cooled and shrunk, and there is a gap between the inner wall of the cavity and the forging. By working of the gas distribution system, the forging is sucked and grabbed by the two vacuum chucks 94. Then, the cylinder 91 retracts to move the forging downwards. Subsequently, the forging is transferred to the downstream unloading station by the power guide rail 92.

[0073] Among them, a mechanical arm is arranged at the unloading station. The mechanical arm can be used to grab and transfer the forging to the conveying line, so as to convey the forging to the downstream process.

[0074] As Figure 10 shown, the front side surface of the mounting plate 93 is fixed with a front and rear extending side plate 95, the side plate 95 is installed with a pair of upward air jet nozzles 96, the two air jet nozzles 96 are communicated with air inlet pipes 961 on the side close to each other, the two air inlet pipes 961 are respectively communicated with two ends of a three-way joint 97, the third end of the three-way joint 97 is communicated with a gas pump (not shown in the figure) through a gas guide main pipe 98, so as to form a complete air jet path, wherein, when the power guide rail 92 drives the vacuum chuck 94 to reach the rear unloading station, the air jet nozzle 96 is synchronously moved to the position corresponding to the lowermost forming die 4.

[0075] When the power guide rail 92 drives the vacuum chuck 94 to reach the rear unloading station, the air jet nozzle 96 is synchronously moved with the mounting plate 93 to the position corresponding to the lowermost forming die 4, at this time the gas pump supplies air to the air jet nozzle 96 through the gas guide main pipe 98, the three-way joint 97 and the air inlet pipe 961, the gas jetted upward by the air jet nozzle 96 can blow and clean the residual oxides and impurities in the cavity of the forming die 4, so as to avoid that the residual impurities affect the next forging forming, and at the same time the cavity can be assisted to cool.

[0076] During the whole process, the lifting of the gas cylinder 91 ensures the height adaptation, the forward and rear movement of the power guide rail 92 realizes the position switching of material taking and unloading, the vacuum chuck 94 is responsible for forging grabbing, and the air jet of the air jet nozzle 96 assists in guaranteeing the processing quality from the aspects of cleaning and cooling, and the whole process of taking out the forging from the cavity of the forming die 4 and moving to the unloading station is efficiently completed through the linkage of various components.

[0077] The control mode of the present application is automatically controlled through a controller, the control circuit of the controller can be realized through simple programming by those skilled in the art, and the power supply also belongs to the common knowledge in the art, so the control mode and circuit connection of the present application will not be explained in detail.

[0078] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or essential characteristics of the present application.
