Technical Field

[0001] This invention relates to the field of aluminum alloy forging processing equipment, specifically to an aerospace aluminum alloy forging processing equipment and method. Background Technology

[0002] Aerospace components typically use lightweight aluminum alloys. To improve the structural strength of these components, forging is often used to extrude heated aluminum alloys. However, existing aluminum alloy forging equipment still has some problems:

[0003] In the process of using aluminum alloy forging processing equipment on the market, in order to ensure that each part of the forging is fully formed, when the equipment extrudes the aluminum alloy raw material, the excess part of the raw material often overflows from the forging structure, producing flash. However, existing forging processing equipment is difficult to remove the flash of the forging quickly, requiring workers to process the flash of the forging through subsequent processing equipment, thus reducing work efficiency.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on existing aluminum alloy forging processing equipment. Summary of the Invention

[0005] The purpose of this invention is to provide an aerospace aluminum alloy forging processing apparatus and method to solve the following problems of existing aluminum alloy forging processing apparatuses mentioned in the background art: In order to ensure that each part of the forging is fully formed, when the apparatus extrudes the aluminum alloy raw material, the excess part of the raw material often overflows from the forging structure, generating flash. Existing forging processing apparatuses cannot quickly remove the flash from the forging, requiring workers to process the flash with subsequent processing equipment, thereby reducing work efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an aerospace aluminum alloy forging processing apparatus and method, comprising:

[0007] The forming base, which can be detachably installed on the workbench by bolts, also includes: symmetrically distributed side tube frames fixedly installed on both sides of the forming base; a horizontally set fixing frame fixedly installed on the top of the side tube frames; a forging rod slidably inserted into the lower part of the fixing frame; convex shafts on both sides of the loading frame rotatably embedded on the outer wall of the middle part of the side tube frames; and a flash shearing mechanism for removing flash from forgings is movably installed on the side of the loading frame facing the forging rod.

[0008] The side tube frame is equipped with a progressive drive module, which can drive the flash shearing mechanism to perform position adjustment and shearing operations in sequence.

[0009] Preferably, the forging head at the lower end of the forging rod is fitted and inserted into the forming cavity at the top of the forming base. The forging head of the forging rod is used to extrude aluminum alloy forging raw materials. The moving end of the bottom of the telescopic cylinder is rotatably connected to the outer wall of the forging rod, and the top of the telescopic cylinder is rotatably mounted on the fixed frame. The telescopic cylinder is tilted so that it can drive the forging rod to move.

The side of the limiting block away from the forged rod is fitted to the lower part of the limiting frame, and the limiting frame is fitted to the side wall of the fixed frame. A transmission cylinder is fixedly connected to the top of the limiting frame. After the limiting block enters the transmission cylinder along the limiting frame, the fixed frame will no longer restrict the rotation of the limiting block, and the forged rod can drive the limiting block to move along the limiting frame.

[0011] Preferably, the two ends of the transmission cylinder are rotatably embedded in the fixed frame and the side cylinder frame, respectively, and the axis of the transmission cylinder and the axis of the forging rod intersect perpendicularly in a vertical plane. The insertion port at the end of the transmission cylinder is smoothly connected to the upper port of the limiting frame, and the end of the transmission cylinder is coaxially fixedly connected to the drive gear. The transmission cylinder can drive the drive gear to rotate synchronously. A vertical baffle is fixedly connected to the outer wall of the fixed frame, and the baffle is fitted to the outer wall of the limiting frame. The drive gear is an incomplete gear, and the drive gear is located inside the side cylinder frame, so that the transmission cylinder can drive the drive gear to rotate.

[0012] Preferably, the progressive drive module includes a toothed plate frame fitted inside the side tube frame. The toothed portion of the toothed plate frame is disposed on the side of the drive gear. The top of the toothed plate frame slides through the top of the side tube frame. A first pull plate and a second pull plate are fixedly connected to the bottom two sides of the toothed plate frame, respectively. The first pull plate and the second pull plate are vertically slidably inserted into the lower part of the side tube frame. The toothed plate frame can drive the first pull plate and the second pull plate to move vertically inside the side tube frame. A first control groove is formed on the side wall of the first pull plate, and the first control groove has an inverted "L" shape. A second control groove is formed on the side wall of the second pull plate, and the height of the inclined groove of the second control groove is lower than the height of the top horizontal groove of the first control groove, so that the toothed plate frame can drive the first pull plate and the second pull plate to move.

[0013] Preferably, a force-bearing rod is fixedly connected to one side of the loading frame, and the axis of the force-bearing rod is parallel to the axis of the loading frame. An arc-shaped groove is formed on the side wall of the side cylinder frame, and the center of the arc-shaped groove is on the rotation axis of the loading frame. The top of the arc-shaped groove is on the moving path of the vertical groove part of the first control groove. When the first pull plate drives the force-bearing rod to move through the first control groove, the force-bearing rod will drive the loading frame to rotate along the arc-shaped groove. The bottom end of the arc-shaped groove is fitted with and passes through the force-bearing rod, and the end of the force-bearing rod away from the loading frame is fitted with the first control groove, so that the first pull plate can drive the force-bearing rod to rotate along the arc-shaped groove.

[0014] Preferably, a tension rod is rotatably and slidably installed at the rotation axis of the loading frame. The tension rod can move axially within the loading frame. The end of the tension rod away from the loading frame is rotatably embedded in a horizontal guide block, and the horizontal guide block is slidably installed on the inner wall of the side cylinder frame. A thrust rod is horizontally fixedly connected to the side wall of the horizontal guide block, and the thrust rod is inserted into the vertical groove at the top of the second control groove. When the second pull plate moves, the inclined groove portion on the second control groove can drive the tension rod to move through the horizontal guide block. The body of the tension rod is fixedly installed through the transmission gear plate, and the transmission gear plate is slidably installed on the inner wall of the loading frame, so that the second pull plate can drive the horizontal guide block and the tension rod to move through the thrust rod.

[0015] Preferably, the flash shearing mechanism includes a transmission gear, which is coaxially fixedly connected to the rotating disk. A transmission gear plate is meshed below the transmission gear. The rotating disk is rotatably embedded in the inner wall of the loading frame. A pressure groove is centrally symmetrically distributed on the side of the rotating disk away from the transmission gear, and the distances from the two ends of the pressure groove to the center of the rotating disk are different. The pressure groove has an arc-shaped structure. A pressure rod is inserted into the pressure groove, and a limiting block is fixedly connected to the end of the pressure rod. The limiting blocks are symmetrically distributed on the surface of the rotating disk and are slidably installed on the loading frame. A guide rod is fixedly installed inside the loading frame, and the axis of the guide rod is perpendicular to the axis of the rotating disk. The guide rod slides through the limiting block. An arc-shaped cutter is fixedly connected to the end of the limiting block away from the pressure rod, so that the transmission gear plate can drive the rotating disk to rotate through the transmission gear, and the rotating disk will drive the limiting block to move through the pressure rod.

[0016] A method for machining aerospace aluminum alloy forgings includes the following steps:

[0017] S1: The telescopic cylinder inside the device can drive the forging rod to move within the forming base, thereby forging the high-temperature aluminum alloy raw material into shape;

[0018] S2: After the forging is processed, the telescopic cylinder first drives the forging rod away from the forming base. When the forging head at the bottom of the forging rod just leaves the forming base, the forging rod will drive the limiting block into the insertion port at the end of the transmission cylinder. When the telescopic cylinder continues to retract, the forging rod can drive the transmission cylinder to rotate through the limiting block. The transmission cylinder will drive the drive gear to rotate. Since the drive gear is an incomplete gear, it will drive the gear plate frame to move only after the drive gear rotates at a set angle.

[0019] S3: The toothed plate frame will drive the first pull plate and the second pull plate to move synchronously. The first control groove on the first pull plate will first drive the force rod to rotate 90° along the arc groove. The force rod will drive the loading frame to rotate synchronously. The flash shearing mechanism will cover the flash part of the forging. Then the force rod will enter the vertical groove part of the first control groove.

[0020] S4: Next, the second pull plate will push the push rod to move through the inclined groove of the second control groove. The push rod will drive the horizontal guide block and the pull rod to move. The pull rod will drive the transmission gear to rotate through the transmission gear plate. The transmission gear will drive the pressure rod to move through the pressure groove on the rotating disk. The pressure rod will drive the limiting block to move along the guide rod. The limiting block will drive the corresponding arc-shaped cutter to move. The arc-shaped cutter will be used to remove the flash of the forging.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: This aerospace aluminum alloy forging processing device and method has the ability to automatically shear the flash of forgings, and can quickly remove the flash after forging processing, thereby improving work efficiency. In addition, the device is equipped with a forging rod structure that automatically deflects after moving upward, which is safer than the traditional vertical downward forging rod. In case of worker misoperation, the deflected forging rod will not directly squeeze the human body. The specific details are as follows:

[0022] 1. The progressive drive module includes a toothed plate frame fitted inside the side cylinder frame. A first pull plate and a second pull plate are fixedly connected to the bottom two sides of the toothed plate frame, respectively. A first control groove is formed on the side wall of the first pull plate, and the first control groove has an inverted "L" shape. A second control groove is formed on the side wall of the second pull plate, and the height of the inclined groove portion of the second control groove is lower than the height of the top horizontal groove of the first control groove. A force-bearing rod is fixedly connected to one side of the loading frame.

The top of the arc-shaped groove is on the moving path of the vertical groove portion of the first control groove, and the bottom of the arc-shaped groove... A force-bearing rod is provided at the end of the loading frame, with the end of the force-bearing rod away from the loading frame fitting into the first control groove. A tension rod is rotatably and slidably installed at the rotation axis of the loading frame, with the end of the tension rod away from the loading frame rotatably embedded in the horizontal guide block. A push rod on the side wall of the horizontal guide block is inserted into the vertical groove at the top of the second control groove, so that the progressive drive module can drive the first pull plate and the second pull plate to move synchronously. At this time, the first pull plate can drive the loading frame to rotate along the arc groove through the force-bearing rod, and the second pull plate can drive the tension rod to move through the horizontal guide block. The tension rod drives the flash shearing mechanism to run through the transmission gear to perform flash removal operation.

[0023] 2. Symmetrically distributed limiting blocks are fixedly installed on the side wall of the forging rod. The limiting blocks are slidably embedded in the vertical groove at the bottom of the fixed frame. The side of the limiting block away from the forging rod is attached to the lower part of the limiting frame. The top of the limiting frame is fixedly connected to the side wall of the transmission cylinder. The telescopic cylinder is tilted. The two ends of the transmission cylinder are respectively rotatably embedded in the fixed frame and the side cylinder frame. The axis of the transmission cylinder and the axis of the forging rod intersect perpendicularly in a vertical plane. The inlet at the end of the transmission cylinder is smoothly connected to the upper port of the limiting frame. The end of the transmission cylinder is coaxially fixed and connected to the drive gear. After the telescopic cylinder drives the forging rod to detach from the forming base, the limiting blocks on the forging rod enter the transmission cylinder along the limiting frame. The fixed frame will no longer restrict the rotation of the limiting blocks. The telescopic cylinder will drive the forging rod to rotate. The limiting blocks on the forging rod drive the transmission cylinder to rotate synchronously. The transmission cylinder can drive the drive gear to rotate. Attached Figure Description

[0040] Please see Figures 1-14 This invention provides a technical solution: a processing device and method for aerospace aluminum alloy forgings, comprising:

[0041] The forming base 1, which can be detachably installed on the workbench by bolts, also includes: symmetrically distributed side tube frames 2 fixedly installed on both sides of the forming base 1; a horizontally set fixing frame 6 fixedly installed on the top of the side tube frame 2; a forging rod 3 slidably inserted into the lower part of the fixing frame 6; convex shafts on both sides of the loading frame 15 rotatably embedded on the outer wall of the middle part of the side tube frame 2; and a flash shearing mechanism 22 for removing flash from forgings is movably installed on the side of the loading frame 15 facing the forging rod 3.

[0042] The side tube frame 2 is equipped with a progressive drive module, which can drive the flash shearing mechanism 22 to perform position adjustment and shearing operations in sequence.

[0043] The forging head at the lower end of the forging rod 3 is fitted into the forming cavity at the top of the forming base 1. The forging head of the forging rod 3 is used to extrude aluminum alloy forging raw materials. The moving end of the bottom of the telescopic cylinder 5 is rotatably connected to the outer wall of the forging rod 3, and the top of the telescopic cylinder 5 is rotatably mounted on the fixed frame 6. The telescopic cylinder 5 is tilted. When the telescopic cylinder 5 drives the forging rod 3 to move upward, since the two sides of the forging rod 3 are fitted into the lower inner wall of the fixed frame 6, symmetrically distributed limiting blocks 4 are fixedly installed on the side wall of the forging rod 3, and the limiting blocks 4 are slidably embedded in the vertical groove at the lower part of the fixed frame 6. The side of the limiting block 4 away from the forging rod 3 is fitted into the lower part of the limiting frame 7, and the limiting frame 7 is fitted into the side wall of the fixed frame 6. The top of the limiting frame 7 is fixedly connected to the transmission cylinder 8. After the limiting block 4 enters the transmission cylinder 8 along the limiting frame 7, the fixed frame 6... The limiting block 4 will no longer be restricted from rotating. At this time, the forging rod 3 will drive the limiting block 4 to enter the transmission cylinder 8 along the limiting frame 7. The two ends of the transmission cylinder 8 are respectively rotatably embedded in the fixed frame 6 and the side cylinder frame 2. The axis of the transmission cylinder 8 and the axis of the forging rod 3 intersect perpendicularly in the vertical plane. The insertion port at the end of the transmission cylinder 8 is smoothly connected to the upper port of the limiting frame 7. The end of the transmission cylinder 8 is coaxially fixed and connected to the drive gear 9. The transmission cylinder 8 can drive the drive gear 9 to rotate synchronously. A vertical baffle 23 is fixedly connected to the outer wall of the fixed frame 6. The baffle 23 is attached to the outer wall of the limiting frame 7. The drive gear 9 is an incomplete gear and is located inside the side cylinder frame 2. At this time, the telescopic cylinder 5 can drive the forging rod 3 to deflect. The forging rod 3 will drive the transmission cylinder 8 to rotate through the limiting block 4. The transmission cylinder 8 will drive the drive gear 9 to rotate.

[0044] The progressive drive module includes a toothed plate frame 10 fitted inside the side tube frame 2. The toothed portion of the toothed plate frame 10 is located on the side of the drive gear 9. The top of the toothed plate frame 10 slides through the top of the side tube frame 2. A first pull plate 11 and a second pull plate 16 are fixedly connected to the bottom two sides of the toothed plate frame 10, respectively. The first pull plate 11 and the second pull plate 16 are vertically slidably inserted into the lower part of the side tube frame 2. The toothed plate frame 10 can drive the first pull plate 11 and the second pull plate 16 to move vertically within the side tube frame 2. A first control groove 12 is formed on the side wall of the first pull plate 11, and the first control groove 12 has an inverted "L" shape. A second control groove 17 is formed on the side wall of the second pull plate 16, and the height of the inclined groove portion of the second control groove 17 is lower than the top of the first control groove 12. The height of the transverse groove allows the drive gear 9 to drive the first pull plate 11 and the second pull plate 16 to move upward synchronously via the gear plate frame 10. A force-bearing rod 14 is fixedly connected to one side of the loading frame 15, and the axis of the force-bearing rod 14 is parallel to the axis of the loading frame 15. An arc-shaped groove 13 is provided on the side wall of the side cylinder frame 2, and the center of the arc-shaped groove 13 is on the rotation axis of the loading frame 15. The top of the arc-shaped groove 13 is on the moving path of the vertical groove portion of the first control groove 12. When the first pull plate 11 drives the force-bearing rod 14 to move via the first control groove 12, the force-bearing rod 14 will drive the loading frame 15 to rotate along the arc-shaped groove 13. The bottom end of the arc-shaped groove 13 is fitted with and passes through the force-bearing rod 14, and the end of the force-bearing rod 14 away from the loading frame 15 is fitted with the first control groove 12. At this time, the first pull plate 11 will drive the loading frame 15 to rotate along the arc groove 13 through the force rod 14. Since the tension rod 20 is rotatably and slidably installed at the rotation axis of the loading frame 15, the tension rod 20 can move axially within the loading frame 15. The end of the tension rod 20 away from the loading frame 15 is rotatably embedded in the horizontal guide block 19, and the horizontal guide block 19 is slidably installed on the inner wall of the side cylinder frame 2. A thrust rod 18 is horizontally fixedly connected to the side wall of the horizontal guide block 19, and the thrust rod 18 is fitted and inserted into the vertical groove at the top of the second control groove 17. When the second pull plate 16 moves, the inclined groove part on the second control groove 17 can drive the tension rod 20 to move through the horizontal guide block 19. The rod body of the tension rod 20 is fixedly installed through the transmission gear plate 21, and the transmission gear plate 21 is slidably installed. Mounted on the inner wall of the loading frame 15, the second pull plate 16 moves the horizontal guide block 19 and the pull rod 20 via the push rod 18. The pull rod 20 rotates the transmission gear plate 21, which in turn rotates the transmission gear 2201.

The transmission gear plate 21 is meshed below the transmission gear 2201. The rotating disk 2202 is rotatably embedded in the inner wall of the loading frame 15. A centrally symmetrical pressure groove 2203 is provided on the side of the rotating disk 2202 away from the transmission gear 2201. The distances from the two ends of the pressure groove 2203 to the center of the rotating disk 2202 are different, and the pressure groove 2203 has an arc-shaped structure.A pressure rod 2204 is fitted and inserted into the pressure groove 2203, and a limiting block 2205 is fixedly connected to the end of the pressure rod 2204. The limiting blocks 2205 are symmetrically distributed on the surface of the rotating disk 2202 and are slidably mounted on the loading frame 15. A guide rod 2206 is fixedly mounted inside the loading frame 15, and the axis of the guide rod 2206 is perpendicular to the axis of the rotating disk 2202. The guide rod 2206 slides through the limiting block 2205. An arc-shaped cutter 2207 is fixedly connected to the end of the limiting block 2205 away from the pressure rod 2204. At this time, the transmission gear 2201 will drive the rotating disk 2202 to rotate synchronously. The pressure groove 2203 on the rotating disk 2202 will drive the limiting block 2205 to move through the corresponding pressure rod 2204, and the limiting block 2205 will drive the arc-shaped cutter 2207 to move.

[0045] A method for machining aerospace aluminum alloy forgings includes the following steps:

[0046] S1: The telescopic cylinder 5 inside the device can drive the forging rod 3 to move within the forming base 1, thereby forging the high-temperature aluminum alloy raw material into shape;

[0047] S2: After the forging is completed, the telescopic cylinder 5 first drives the forging rod 3 away from the forming base 1. When the forging head at the bottom of the forging rod 3 just leaves the forming base 1, the forging rod 3 will drive the limiting block 4 into the insertion port at the end of the transmission cylinder 8. When the telescopic cylinder 5 continues to retract, the forging rod 3 can drive the transmission cylinder 8 to rotate through the limiting block 4. The transmission cylinder 8 will drive the drive gear 9 to rotate. Since the drive gear 9 is an incomplete gear, it will drive the toothed plate frame 10 to move only after the drive gear 9 rotates at a set angle.

[0048] S3: The toothed plate frame 10 will drive the first pull plate 11 and the second pull plate 16 to move synchronously. The first control groove 12 on the first pull plate 11 will first drive the force rod 14 to rotate 90° along the arc groove 13. The force rod 14 will drive the loading frame 15 to rotate synchronously. The flash shearing mechanism 22 will cover the flash part of the forging. Then the force rod 14 will enter the vertical groove part of the first control groove 12.

[0049] S4: Next, the second pull plate 16 will push the push rod 18 to move through the inclined groove of the second control groove 17. The push rod 18 will drive the horizontal guide block 19 and the tension rod 20 to move. The tension rod 20 will drive the transmission gear 2201 to rotate through the transmission gear plate 21. The transmission gear 2201 will drive the pressure rod 2204 to move through the pressure groove 2203 on the rotating disk 2202. The pressure rod 2204 will drive the limiting block 2205 to move along the guide rod 2206. The limiting block 2205 will drive the corresponding arc-shaped cutter 2207 to move.

2. A method for processing aerospace aluminum alloy forgings using an aerospace aluminum alloy forging processing apparatus as described in claim 1, characterized in that, Includes the following steps: S1: The telescopic cylinder (5) inside the device can drive the forging rod (3) to move within the forming base (1), thereby forging the high-temperature aluminum alloy raw material into shape; S2: After the forging is completed, the telescopic cylinder (5) first drives the forging rod (3) away from the forming base (1). When the limiting block (4) on the forging rod (3) enters the transmission cylinder (8), the forging rod (3) can drive the transmission cylinder (8) to rotate. The transmission cylinder (8) drives the toothed plate frame (10) in the progressive drive module to move through the drive gear (9). S3: The progressive drive module moves upward as a whole. The first pull plate (11) in the progressive drive module will first drive the force rod (14) to rotate 90°. The force rod (14) drives the loading frame (15) to rotate synchronously. The flash shearing mechanism (22) will cover the flash of the forging. S4: Next, the second pull plate (16) in the progressive drive module will drive the horizontal guide block (19) and the pull rod (20) to move through the push rod (18). The pull rod (20) drives the flash shearing mechanism (22) to run through the transmission tooth plate (21). The arc cutter (2207) in the flash shearing mechanism (22) moves synchronously, thereby removing the flash of the forging.
