Description

Technical Field

[0001] This application relates to the field of straightening mechanism technology, and more specifically, to a straightening mechanism for an aluminum alloy extrusion forming equipment. Background Technology

[0002] Aluminum alloy profiles are one of the most widely used non-ferrous metal structural materials in industry. Aluminum alloys have low density but high strength, approaching or exceeding that of high-quality steel. They have good plasticity and can be processed into various profiles. They also have excellent electrical conductivity, thermal conductivity, and corrosion resistance. They are widely used in industry, second only to steel in terms of usage. Some aluminum alloys can be heat-treated to obtain good mechanical properties, physical properties, and corrosion resistance. Due to the long length of aluminum alloy tubes, local bending can easily occur at the stress points when moving or hoisting them in the workshop. In addition, irregularly shaped aluminum materials with local bulges are also prone to appear during processing and transportation. Straightening equipment is usually required to straighten the tubes.

[0003] A search revealed that patent CN218340710U discloses "a straightening device for processing aluminum alloy profiles, belonging to the field of aluminum alloy profile straightening technology, including a positioning plate and a worktable for straightening aluminum alloy profiles... This straightening device for processing aluminum alloy profiles is easy to adjust and can straighten aluminum alloy tubes of different specifications, while ensuring the stability of the aluminum alloy tubes during the straightening process." However, after straightening an aluminum alloy tube and removing it to install the next aluminum alloy tube, it is necessary to manually tighten two fixing screws to release the fixation, then remove it, install the aluminum alloy tube to be straightened, and then tighten two fixing bolts to fix it. This operation method is cumbersome, resulting in a long downtime for the device and thus affecting work efficiency.

[0004] To address the aforementioned problems, this application provides a straightening mechanism for an aluminum alloy extrusion forming equipment. Utility Model Content

[0005] One objective of this application is to provide a straightening mechanism for an aluminum alloy extrusion forming equipment, comprising a supporting base plate, a worktable disposed above the supporting base plate, a fixed frame fixedly connected to the top of the worktable, a second electric push rod fixedly connected to the top of the fixed frame, the output end of the second electric push rod extending to the bottom of the fixed frame and fixedly connected to a straightening block, a groove formed on the top of the worktable, two operating tables slidably connected inside the groove and fixedly connected to each other, a limit rod fixedly connected inside the groove, and the two operating tables slidably sleeved on the outside of the limit rod, a threaded rod rotatably connected inside the groove, and the two operating tables threadedly sleeved on the outside of the threaded rod, a first motor for driving the threaded rod to rotate fixedly connected to the outside of the worktable, a support block disposed at the middle of the top of the operating table, and a fixing mechanism for fixing the workpiece to be straightened disposed on the operating table.

[0006] Furthermore, the supporting base plate is connected to the worktable via a lifting mechanism. The lifting mechanism includes two first electric push rods, which are symmetrically fixedly connected to the top of the supporting base plate. The output end of each first electric push rod is fixedly connected to the bottom surface of the worktable.

[0007] Furthermore, rectangular tubes are fixedly connected to the top four corners of the support base plate, and rectangular rods are slidably inserted into the inside of the rectangular tubes. The top ends of the rectangular rods are fixedly connected to the bottom surface of the workbench.

[0008] Furthermore, the inner wall of the groove is symmetrically fixedly connected with a limiting strip, and the outer sides of both operating tables are provided with limiting grooves that are adapted to the limiting strips.

[0009] Furthermore, the operating platform has an internal cavity, and symmetrical sliding grooves communicating with the cavity are formed on the top of the operating platform. The fixing mechanism includes a second motor, which is mounted on the outside of the operating platform. The drive end of the second motor is connected to a bidirectional lead screw. The bidirectional lead screw is rotatably connected inside the two sliding grooves. Limiting blocks are also slidably connected inside the sliding grooves. The two limiting blocks are symmetrically threaded onto the outside of the bidirectional lead screw. Each limiting block has a placement hole and a rectangular hole. The bottom surface of each limiting block has symmetrical openings communicating with the rectangular holes. A sliding hole is provided, and a vertical plate is slidably inserted inside the sliding hole. A connecting plate is provided inside the rectangular hole. A pressure plate is provided on the upper side of the placement hole. A through hole is provided between the placement hole and the rectangular hole. A sliding block is provided inside the through hole. The two ends of the sliding block are fixedly connected to the connecting plate and the pressure plate, respectively.

[0010] Furthermore, both sides of the bidirectional lead screw are provided with slide rods, the two ends of the slide rods are fixedly connected to the inner wall of the sliding groove, and the limiting block is slidably sleeved on the outside of the slide rod.

[0011] The beneficial effects of this application are:

[0012] 1. When straightening aluminum alloy tubes on one workbench, the operator uses a fixing mechanism to fix the next aluminum alloy tube to be straightened on another workbench. When the aluminum alloy tube on one workbench is straightened, the first motor is controlled to drive the threaded rod to rotate, thereby causing the two workbench to move inside the groove. This moves the straightened aluminum alloy tube to one side of the fixing frame, while the bent protrusion of the aluminum alloy tube to be straightened on the other workbench moves to the underside of the straightening block for straightening. During the straightening process, the operator removes the straightened aluminum alloy tube, thus achieving simultaneous straightening and removal of aluminum alloy tubes, avoiding excessive downtime and affecting work efficiency.

[0013] 2. Controlling the third electric push rod to retract and move the rectangular plate downwards, the rectangular plate moves the rectangular sleeve downwards, the rectangular sleeve moves the vertical plate downwards, thereby moving the connecting plate and sliding block downwards, and then moving the pressure plate downwards to quickly fix both ends of the aluminum alloy tube, further improving work efficiency.

[0024] Example:

[0025] Please see Figure 1 and Figure 2This application discloses a straightening mechanism for an aluminum alloy extrusion forming equipment, used to straighten an aluminum alloy tube. The straightening mechanism includes a support base plate 1, a worktable 5 above the support base plate 1, a fixed frame 10 fixedly connected to the top of the worktable 5, the fixed frame 10 being located in the middle of one side of the worktable 5, approximately L-shaped, its vertical part fixed to the middle of one side of the worktable 5, and its horizontal part extending to the top of the worktable 5. A second electric push rod 11 is fixedly connected to the top of the fixed frame 10, the output end of the second electric push rod 11 extending to the bottom of the fixed frame 10 and fixedly connected to a straightening block 12. The second electric push rod 11 is mounted on the horizontal part of the fixed frame 10. The extension of the second electric push rod 11 can drive the straightening block 12 to descend, and the straightening block 12 applies pressure to the bent part of the aluminum alloy tube multiple times, thus straightening the bent part of the aluminum alloy tube. A groove 6 is provided on the top of the worktable 5, the groove 6 extending along a first direction, the first direction being the length direction of the worktable 5. Two operating platforms 14 are internally slidably connected and fixedly connected. The sliding direction is the first direction. A limiting rod 7 extending along the first direction is fixedly connected inside the groove 6, and the two operating platforms 14 are slidably sleeved on the outside of the limiting rod 7. The limiting rod 7 plays a role in limiting the operation platform 14 and improving the stability of the operation platform 14 when moving in the groove 6. A threaded rod 9 is rotatably connected inside the groove 6. The threaded rod 9 extends along the first direction, and the two operating platforms 14 are threadedly sleeved on the outside of the threaded rod 9. A first motor 8 for driving the threaded rod 9 to rotate is fixedly connected to the outside of the worktable 5. Controlling the first motor 8 to drive the threaded rod 9 to rotate, thereby controlling the two operating platforms 14 to move alternately to the bottom of the straightening block 12, realizing the alternating use of the two operating platforms 14 and improving work efficiency. A support block 13 is set at the top middle of the operating platform 14. The support block 13 plays a role in supporting the aluminum alloy tube. A fixing mechanism for fixing the part to be straightened is also set on the operating platform 14.

[0026] Please see Figure 1 and Figure 2The support base plate 1 is connected to the worktable 5 via a lifting mechanism. The lifting mechanism includes two first electric push rods 2. The top of the support base plate 1 is symmetrically and fixedly connected to the two first electric push rods 2. The retraction or extension of the first electric push rods 2 can drive the worktable 5 to move downward or upward, thereby facilitating the height adjustment of the worktable 5. The output end of the first electric push rod 2 is fixedly connected to the bottom end face of the worktable 5. Rectangular tubes 4 are fixedly connected to the four corners of the top of the support base plate 1. Rectangular rods 3 are slidably inserted into the inside of the rectangular tubes 4. When the worktable 5 is raised or lowered, the worktable 5 drives the rectangular rods 3 to move inside the rectangular tubes 4, thereby improving the stability of the worktable 5 when it is raised or lowered. The top end of the rectangular rods 3 is fixedly connected to the bottom end face of the worktable 5. Limiting strips are symmetrically and fixedly connected to the inner wall of the groove 6. Limiting grooves that match the limiting strips are opened on the outer side of the two operating tables 14. The limiting strips and limiting grooves extend along the first direction. The cooperation of the limiting strips and limiting grooves limits the operating tables 14 and improves the stability of the operating tables 14 when they move.

[0027] Please see Figure 1 , Figure 2 and Figure 3The operating table 14 has an internal cavity 19. The top of the operating table 14 has symmetrical sliding grooves communicating with the cavity 19. The axis of symmetry extends along a second direction, which is perpendicular to the first direction and is the width direction of the worktable 5. The fixing mechanism includes a second motor 15, which is mounted on the outside of the operating table 14. The drive end of the second motor 15 is connected to a bidirectional lead screw 21, which is rotatably connected to the inside of two sliding grooves. A circular hole is formed between two adjacent sliding grooves, and the bidirectional lead screw 21 is rotatably connected to the inside of the circular hole. Both ends of the bidirectional lead screw 21 are rotatably connected to the inner wall of the sliding groove through bearings. A limiting block 16 is also slidably connected inside each sliding groove. Two limiting blocks 16 on the same operating table 14 are symmetrically threaded onto the outside of the bidirectional lead screw 21. The limiting block 16 has a placement hole 23 and a rectangular hole 28. The through direction of both holes is the first direction, and the rectangular hole 28 is located within the placement hole 23. Above, the bottom end of the limiting block 16 is symmetrically provided with a sliding hole communicating with the rectangular hole 28. Its axis of symmetry extends along the first direction, and the sliding hole is vertical. A vertical plate 26 is slidably inserted into the sliding hole. A connecting plate 25 is provided inside the rectangular hole 28, and the connecting plate 25 is fixedly connected to the vertical plate 26. A pressure plate 27 is provided on the upper side of the placement hole 23. A through hole is provided between the placement hole 23 and the rectangular hole 28. The through hole is vertical, and the inside of the through hole is provided with... A sliding block 24 is provided, and the two ends of the sliding block 24 are fixedly connected to the connecting plate 25 and the pressure plate 27 respectively. A third electric push rod 17 is fixedly connected to the inner bottom wall of the cavity 19. The extension and retraction direction of the third electric push rod 17 is vertical. A rectangular plate 18 is fixedly connected to the output end of the third electric push rod 17. The length direction of the rectangular plate 18 is the first direction. Rectangular sleeves 20 are slidably sleeved on the outer sides of both ends of the rectangular plate 18. The rectangular sleeves 20 are fixedly connected to the end of the vertical plate 26 away from the connecting plate 25.

[0028] By controlling the second motor 15 to drive the bidirectional lead screw 21 to rotate, the rotation of the bidirectional lead screw 21 allows the two limiting blocks 16 to move towards or relative to each other within the two sliding grooves, thus facilitating the straightening of aluminum alloy tubes of different lengths and expanding the applicability of the device. Specifically, when the two limiting blocks 16 move relative to or towards each other, the limiting blocks 16 drive the vertical plate 26 to move, and the vertical plate 26 drives the rectangular sleeve 20 to slide on the outside of the rectangular plate 18.

[0029] Please see Figure 2 and Figure 3Both sides of the bidirectional lead screw 21 are provided with slide rods 22. The slide rods 22 extend along the first direction and the two ends of the slide rods 22 are fixedly connected to the inner wall of the sliding groove. The limiting block 16 is slidably sleeved on the outside of the slide rods 22. The two slide rods 22 located inside the sliding groove play a role in limiting the sliding of the limiting block 16. When the limiting block 16 moves, it slides on the outside of the two slide rods 22, which improves the stability of the limiting block 16 when it moves.

[0030] The implementation principle of this application embodiment is as follows: First, the aluminum alloy tube to be straightened is placed inside the placement hole 23 on the two limit blocks 16 on the same operating table 14, and the protruding part of the bent aluminum alloy tube is placed directly below the straightening block 12. The third electric push rod 17 is controlled to retract and drive the rectangular plate 18 to move downward. The rectangular plate 18 moves downward and drives the rectangular sleeve 20 to move downward. The rectangular sleeve 20 moves downward and drives the vertical plate 26 to move downward, thereby driving the connecting plate 25 and the sliding block 24 to move downward, and then driving the pressure plate 27 to move downward to fix the aluminum alloy tube.

[0031] Secondly, the second electric push rod 11 is controlled to drive the straightening block 12 to descend. The straightening block 12 applies pressure to the bent part of the aluminum alloy tube multiple times, thereby straightening the bent part of the aluminum alloy tube.

[0032] When straightening an aluminum alloy tube on one operating table 14, the operator uses a fixing mechanism to fix the next aluminum alloy tube to be straightened onto another operating table 14. When the aluminum alloy tube on one operating table 14 is straightened, the first motor 8 is controlled to drive the threaded rod 9 to rotate, thereby causing the two operating tables 14 to move inside the groove 6. This moves the straightened aluminum alloy tube to one side of the fixing frame 10, while the bent protrusion of the aluminum alloy tube to be straightened fixed on the other operating table 14 moves to the underside of the straightening block 12 for straightening. During the straightening process, the operator removes the straightened aluminum alloy tube, thus achieving simultaneous straightening and removal of the aluminum alloy tube, avoiding excessive downtime that could affect work efficiency.

[0033] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and application concept of this application, should be included within the scope of protection of this application.
