Description

Technical Field

[0001] This invention belongs to the field of aluminum profile straightening technology, specifically referring to a stamping processing equipment for straightening aluminum profiles. Background Technology

[0002] Profiles are generally long and narrow. Although the cross-sections vary, the bottom and top are mostly flat. Due to their long length, they are prone to slight bending during storage and transportation. Therefore, it is necessary to check the bending condition of the profiles and straighten them before use. For aluminum profiles, the aforementioned testing and straightening processes still need to be completed manually, and manual operation is highly dependent on the experience and skills of the workers.

[0003] Currently, when conducting bending inspections on aluminum profiles, conventional methods such as manual visual inspection or feeler gauge inspection are mostly used. This not only results in high labor costs, but also requires frequent inspections during the straightening process. The low efficiency of manual inspections can be amplified as the number of inspections increases.

[0004] Because aluminum profiles have a certain degree of elasticity, simply pressing a bent profile flat will cause it to spring back slightly after the pressure is removed. The extent of this springback is related to factors such as the material's formulation, the shape of the cross-section, and the thickness of the sheet material, making it difficult to standardize. This is precisely why the cold pressing and straightening effect of aluminum profiles is unstable and often requires the use of other complex processes. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a stamping processing equipment for straightening aluminum profiles. The present invention adopts an over-extrusion method so that the aluminum profile can be straight after springback. In this process, since the over-extrusion range is unknown, the present invention creatively proposes an extrusion straightening component and a ratchet temporary locking component. By extruding multiple times and increasing the stamping amount by a small amount each time, and performing a re-inspection after each extrusion, the aluminum profile is straightened.

[0006] This solution uses the support block under the workpiece as the contact point in the detection circuit. When the aluminum profile comes into contact with the detection table, the detection table will be connected as a branch circuit. The detection tables are connected in parallel. By analyzing the path and open circuit of the detection table, the flatness of the bottom of the current profile workpiece can be quickly and accurately determined.

[0007] The side pressure blocks and the straightening base can abut against the upper and lower sides of the profile from both directions to fix and clamp the profile. Then, the straightening pressure blocks can apply pressure to the profile to correct it. Through the relative sliding of the straightening pressure blocks and the side pressure blocks, the arched part in the middle of the profile can be squeezed downward to correct the bending of the profile.

[0008] Since the hydraulic drive itself has insufficient control precision over the stamping stroke, the present invention proposes a springback sensing component, which can not only send a signal when the straightening block extends relative to the side block, but also release the relative locking between the straightening block and the side block by actively retracting, thus preparing for the next straightening.

[0009] The technical solution adopted by the present invention is as follows: The present invention proposes a stamping processing equipment for straightening aluminum profiles, including a contact detection component, an extrusion straightening component, a ratchet temporary locking component, a springback sensing component, a hydraulic lifting component, a traverse component, and a frame. The contact detection component is disposed on the frame, the extrusion straightening component is disposed below the hydraulic lifting component, the ratchet temporary locking component is symmetrically disposed in the extrusion straightening component, the springback sensing component is disposed between the two sets of ratchet temporary locking components, and the traverse component is symmetrically disposed on the frame. The contact detection assembly includes a detection plate, a detection stage, and two independent correction bases. The detection stage is located on the detection plate, and the correction bases are located on the detection plate. The top surface of each detection stage is at the same height as the top surface of the transverse component.

[0010] Preferably, the array of testing stations is provided in several groups. No testing station is provided at the position of the correction base on the testing plate. When the aluminum profile comes into contact with the testing station, the testing station will be connected as a branch circuit. The testing stations are connected in parallel. By analyzing the path and open circuit of the testing station, it is possible to determine whether the aluminum profile at the current position is deformed.

[0011] The continuity status of each testing station can be displayed through a screen or light group. By analyzing the light group, it is possible to determine whether the profile has undergone bending deformation at its current position and the direction of the bending deformation.

[0012] Furthermore, the extrusion straightening assembly includes side pressure blocks, straightening pressure blocks, and springs. The side pressure blocks are symmetrically arranged on both sides of the straightening pressure block and are fixedly connected to the hydraulic lifting assembly. The straightening pressure block has symmetrically arranged laterally extending sliding parts on both sides, which are longitudinally engaged and slidably disposed in the side pressure blocks. The spring is disposed between the side pressure blocks and the straightening pressure block. The side pressure blocks are located directly above the straightening base. The side pressure blocks and the straightening pressure block are driven to rise and fall by the hydraulic lifting assembly, and the profile is straightened by the misaligned extrusion of the side pressure blocks and the straightening pressure block.

[0013] The side pressure blocks and the straightening base can be used to press against the two sides of the straightening position from the top and bottom. The straightening pressure blocks can apply pressure to the profile to straighten it.

[0014] By controlling the relative slippage of the correction block and the side block, the extreme position of the correction block's descent can be controlled, thereby controlling the amplitude of the correction pressure.

[0015] Furthermore, the ratchet temporary locking assembly includes a hydraulic box, a locking tongue, and a hydraulic pipe. The hydraulic box is located in the side pressure block, the locking tongue is engaged and slidably located in the hydraulic box, and one end of the hydraulic pipe is located in the hydraulic box.

[0016] Preferably, the side of the correcting block is provided with a ratchet row, and the end of the locking tongue is provided with a ratchet portion that matches the ratchet row. When the correcting block slides vertically relative to the side block, the locking tongue will move laterally and retract in the hydraulic box to avoid the position due to ratchet interference.

[0017] By cooperating with the ratchet row and ratchet section, the straightening block can maintain its current relative position and retract together after extending relative to the side block, thereby setting the pre-position for the next extrusion and achieving the technical goal of increasing the extrusion depth by one level each time.

[0018] Furthermore, the rebound sensing component includes a hydraulic cylinder, a piston, and a locking and return spring. The hydraulic cylinder is fixed to the hydraulic lifting component, the piston is engaged and slidably disposed in the hydraulic cylinder, the other end of the hydraulic pipe is disposed on the hydraulic cylinder, and the locking and return spring is disposed between the two pistons.

[0019] Preferably, the rebound sensing component further includes two electromagnets, which are respectively disposed on two pistons. When the two electromagnets are energized, they will attract each other. The electromagnets are also provided with sensing contacts.

[0020] The sensing contact can send a signal when the correcting block extends one level relative to the side block, thus solving the problem of insufficient control precision of the hydraulic system itself, making it difficult to sense small displacements.

[0021] Furthermore, the hydraulic lifting assembly includes a gantry support, a hydraulic cylinder, a telescopic guide rod, and a lifting frame. The gantry support is mounted on the machine frame, and the hydraulic cylinder and the telescopic guide rod are mounted on the gantry support. The ends of the hydraulic cylinder and the telescopic guide rod are respectively mounted on the straightening pressure block and the side pressure block.

[0022] Preferably, the lifting frame is fixed to the outside of the side pressure block, the correcting pressure block is slidably disposed in the lifting frame, and the hydraulic cylinder is fixed to the outside of the lifting frame.

[0023] Furthermore, the transverse assembly includes a transverse conveyor belt, a transverse support, and support legs. The support leg array is disposed on the transverse support, the support legs are fixed to the frame, and the transverse conveyor belt is disposed on the transverse support.

[0024] The lateral movement component can control the lateral movement of the profile, allowing the profile to switch back and forth between the inspection station and the correction station, achieving the technical effect of multiple small-amplitude corrections.

[0025] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The continuity and disconnection status of each testing station can be displayed through a screen or light group. By analyzing and judging the light group, it can be determined whether the profile has undergone bending deformation at its current position and the direction of bending deformation.

[0026] (2) The side pressure blocks and the straightening base can press against the two sides of the correction position from the top and bottom. The straightening pressure blocks can apply pressure to the profile and correct it.

[0027] (3) By controlling the relative slippage of the correction block and the side block, the limit position of the correction block's descent can be controlled, thereby controlling the amplitude of the correction pressure.

[0028] (4) Through the cooperation of the ratchet row and the ratchet part, the straightening pressure block can maintain its current relative position and retract together after it extends relative to the side pressure block, thereby setting the forward position for the next extrusion, thus achieving the technical purpose of increasing the extrusion depth by one level each time.

[0029] (5) The sensing contact can send a signal when the correcting block extends one level relative to the side block, thereby solving the problem that the hydraulic system itself has insufficient control accuracy and is difficult to sense small displacements.

[0030] (6) The lateral movement of the profile can be controlled by the lateral movement component, so that the profile can switch back and forth between the inspection station and the correction station to achieve the technical effect of multiple small-amplitude correction.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0036] like Figures 1-8 As shown, the present invention proposes a stamping processing equipment for straightening aluminum profiles, including a contact detection component 1, an extrusion straightening component 2, a ratchet temporary locking component 3, a springback sensing component 4, a hydraulic lifting component 5, a lateral movement component 6, and a frame 7. The contact detection component 1 is disposed on the frame 7, the extrusion straightening component 2 is disposed below the hydraulic lifting component 5, the ratchet temporary locking component 3 is symmetrically disposed in the extrusion straightening component 2, the springback sensing component 4 is disposed between the two sets of ratchet temporary locking components 3, and the lateral movement component 6 is symmetrically disposed on the frame 7. The contact testing assembly 1 includes a testing plate 11, a testing table 12, and two independent correction bases 13. The testing table 12 is located on the testing plate 11, and the correction bases 13 are located on the testing plate 11. The two correction bases 13 are symmetrically arranged with respect to the central axis of the frame 7, and the width of the correction base 13 is greater than the width of the profile.

[0037] The array of testing stations 12 is set in several groups. No testing station 12 is set at the position of the correction base 13 on the testing plate 11. When the aluminum profile comes into contact with the testing station 12, the testing station 12 will be connected as a branch circuit. The testing stations 12 are connected in parallel. By analyzing the path and open circuit of the testing station 12, it is possible to determine whether the aluminum profile at the current position is deformed.

[0038] The continuity and disconnection status of each testing station 12 can be displayed through a screen or light group. By analyzing and judging the light group, it is possible to know whether the profile has undergone bending deformation at its current position, and the direction of bending deformation.

[0039] The extrusion straightening assembly 2 includes a side pressure block 21, a straightening pressure block 22, and a spring 23. The side pressure block 21 is symmetrically arranged on both sides of the straightening pressure block 22. The side pressure block 21 is fixed in the hydraulic lifting assembly 5. The straightening pressure block 22 has symmetrically arranged laterally extending sliding parts 221 on both sides. The sliding parts 221 are longitudinally engaged and slidably arranged in the side pressure block 21. The spring 23 is arranged between the side pressure block 21 and the straightening pressure block 22.

[0040] The side pressure block 21 is located directly above the straightening base 13, and the profile is located between the side pressure block 21 and the straightening base 13 during straightening. The side pressure block 21 and the straightening base 13 can press against the top and bottom of the correction position from the top and bottom directions respectively, and the straightening pressure block 22 can apply pressure to the profile to correct it.

[0041] The side pressure block 21 is located directly above the straightening base 13. The side pressure block 21 and the straightening pressure block 22 are driven to rise and fall by the hydraulic lifting assembly 5. The profile can be straightened by the misaligned pressing of the side pressure block 21 and the straightening pressure block 22. The extreme position of the straightening pressure block 22 can be controlled by the relative sliding of the straightening pressure block 22 and the side pressure block 21, thereby controlling the amplitude of the straightening pressing.

[0042] The ratchet temporary locking assembly 3 includes a hydraulic box 31, a locking tongue 32, and a hydraulic pipe 33. The hydraulic box 31 is located in the side pressure block 21. The locking tongue 32 is laterally engaged and slidably located in the hydraulic box 31. One end of the hydraulic pipe 33 is located in the hydraulic box 31. The hydraulic box 31 and the hydraulic pipe 33 are filled with transmission oil.

[0043] The straightening block 22 has a ratchet row 222 on its side and a ratchet part 321 that matches the ratchet row 222 at its end. When the straightening block 22 slides vertically relative to the side block 21, the locking tongue 32 will move laterally and retract in the hydraulic box 31 to avoid the ratchet interference.

[0044] By cooperating with the ratchet row 222 and the ratchet part 321, the straightening pressure block 22 can maintain its current relative position and retract together after extending relative to the side pressure block 21, thereby setting the pre-position for the next extrusion and achieving the technical purpose of increasing the extrusion depth by one level each time.

[0045] The rebound sensing component 4 includes a hydraulic cylinder 41, two pistons 42 and a locking and returning spring 44. The hydraulic cylinder 41 is fixed to the hydraulic lifting component 5. The pistons 42 are engaged and slidably disposed in the hydraulic cylinder 41. The other end of the hydraulic pipe 33 is disposed on the hydraulic cylinder 41. The locking and returning spring 44 is disposed between the two pistons 42.

[0046] The rebound sensing component 4 also includes two electromagnets 43, which are respectively mounted on two pistons 42. When the two electromagnets 43 are energized, they will attract each other. The electromagnets 43 are also provided with sensing contacts 431.

[0047] When the straightening block 22 extends one level relative to the side block 21, the locking tongue 32 reaches its maximum lateral movement, and at the same time pushes the two pistons 42 closer together. The two sensing contacts 431 can send a signal when they come into contact, thereby solving the problem that the hydraulic system itself has insufficient control precision and is difficult to sense small displacements.

[0048] The hydraulic lifting assembly 5 includes a gantry support 51, a hydraulic cylinder 52, a telescopic guide rod 53, and a lifting frame 54. The gantry support 51 is mounted on the frame 7. The hydraulic cylinder 52 and the telescopic guide rod 53 are mounted on the gantry support 51. The end of the hydraulic cylinder 52 is mounted on the straightening pressure block 22, and the end of the telescopic guide rod 53 is mounted on the side pressure block 21.

[0049] The lifting frame 54 is fixed to the outside of the side pressure block 21, the straightening pressure block 22 is slidably disposed in the lifting frame 54, and the hydraulic cylinder 41 is fixed to the outside of the lifting frame 54.

[0050] The transverse assembly 6 includes a transverse conveyor belt 61, a transverse support 62, and support legs 63. The support legs 63 are arranged in an array on the transverse support 62 and fixed to the frame 7. The transverse conveyor belt 61 is arranged on the transverse support 62. The top surface of the inspection table 12 is at the same height as the top surface of the transverse conveyor belt 61, and the heights between each inspection table 12 are equal.

[0051] The lateral movement component 6 can control the lateral movement of the profile, thereby allowing the profile to switch back and forth between the inspection station and the correction station, achieving the technical effect of multiple small-amplitude corrections.

[0052] This device can be used for aluminum profiles such as aluminum plates and aluminum squares with flat bottom surfaces.

[0053] In practical use, with the movement direction of the transverse conveyor belt 61 as the X direction, the profile approaches the device from the X direction and is transferred to the transverse assembly 6. First, the transverse conveyor belt 61 places the profile at the inspection station. If the profile is straight, it will contact each inspection station 12 below it, and the branch circuit where the inspection station 12 is located will be connected. The power supply, workpiece, inspection station 12, lamp beads and frame together form a closed loop, where the power supply, workpiece and frame are the main circuit part, and each inspection station 12 and lamp beads are located in the branch circuit. The inspection station 12 is equivalent to the connecting switch between the branch circuit and the main circuit. When the inspection station 12 contacts the workpiece, the switch is closed, and when the inspection station 12 does not contact the workpiece, the switch is open. Each branch circuit is connected in parallel. When the branch circuit where the inspection station 12 is located is connected, its corresponding lamp beads will be lit.

[0054] By analyzing the lighting status of the LEDs in the light cluster, it is possible to determine whether the profile is currently bent and the direction of the bend. If all the LEDs in the row below the profile are lit, it means that the profile is currently in a straight state. At this time, the profile can be moved axially by the external mechanism to inspect the next section of the profile. If the row of LEDs below the profile is lit at both ends and off in the middle, it indicates that the profile in the middle area is arched and not in contact with the testing table 12. In this case, it is necessary to first make a slight axial adjustment to the profile (which can be done by pushing with an external push rod) so that the arched position is in the middle of the equipment, and then start the straightening process to straighten the position: The profile is transferred from the inspection table 12 to the straightening base 13 by the transverse conveyor belt 61. The arched position of the profile is located in the middle of the two straightening bases 13. Then, the straightening block 22 is pushed down by the hydraulic cylinder 52. In the initial state, the straightening block 22 transmits the force to the side block 21 through the sliding part 221 and the spring 23. The side block 21 descends together with the straightening block 22. When the side pressure block 21 and the straightening base 13 simultaneously press against the profile from both sides, the side pressure block 21 cannot continue to descend because the profile below has already pressed against the straightening base 13, while the straightening pressure block 22 can continue to descend because the profile below is suspended in the air.

[0055] When the straightening block 22 descends relative to the side block 21, it pushes the locking tongue 32 to move laterally through the ratchet. When the relative displacement of the two reaches one tooth pitch, the lateral displacement of the locking tongue 32 reaches its maximum. At the same time, the oil in the hydraulic box 31 enters the hydraulic cylinder 41 through the hydraulic pipe 33 and pushes the two pistons 42 to overcome the elastic force of the locking return spring 44 and approach each other. At this time, the two sensing contacts 431 contact each other and send a control signal to change the hydraulic cylinder 52 from extension to retraction. When the hydraulic cylinder 52 begins to retract, the relative displacement of the straightening block 22 and the side block 21 has exceeded one tooth pitch.

[0056] Due to the unidirectional limiting effect of the ratchet, the straightening block 22 remains in a state of being extended relative to the side block 21 when it retracts. Then, the profile is transferred from the straightening base 13 to the inspection table 12 for re-inspection by the transverse conveyor belt 61. If the re-inspection is qualified, the next section of the area is inspected. If the arching persists after re-inspection, return to the straightening base 13 and continue pressing. Since the straightening pressure block 22 is already in a state of protrusion relative to the side pressure block 21, the range of pressing this time will be greater than the previous one, and the pressing will stop after increasing by one tooth pitch. The above method is used to gradually increase the degree of over-extrusion, and a re-inspection is performed after each extrusion until the profile becomes straight.

[0057] If the row of LEDs at the bottom of the profile is off at both ends and lit in the middle, it indicates that the profile in the middle area is bent downwards. In this case, the profile needs to be flipped over by external equipment or manually, and then straightened according to the above straightening method for arching.

[0058] The density of the testing platform 12 is related to the hardness of the profile. For workpieces with low strength, easy bending and deformation and large amplitude, the layout density of the testing platform 12 needs to be increased appropriately. For workpieces with high strength, not easy to bend and deform and small amplitude, the layout density of the testing platform 12 can be reduced appropriately.

[0059] As another new embodiment of the present invention, if the profile itself is large and difficult to move laterally, the lateral conveyor belt 61 can be connected to the contact detection component 1. Through the lateral movement of the contact detection component 1 itself, the profile can also be reciprocated between the detection table 12 and the correction base 13.
