Description

Technical Field

[0001] This utility model belongs to the field of steel beam processing technology, and specifically relates to a straightening device for automotive steel beams. Background Technology

[0002] Straight steel beams are used in vehicle production and maintenance. These beams may be direct vehicle components or indirect components used to manufacture direct components. However, during manufacturing and transportation, steel beams may deform, such as arching or denting, affecting assembly accuracy, device quality, and operational safety. Therefore, it is necessary to straighten deformed steel beams to ensure they meet design dimensions and tolerances, guaranteeing the overall performance and durability of the vehicle. Current technology uses hydraulic straightening machines or mechanical presses for straightening steel beams. The beam is supported on a support structure, and then a mold or pressure head applies a downward counterforce to plastically deform the material and restore its flatness.

[0003] However, in the existing technology, steel beams are straightened in a cooled state. Since the plasticity of steel decreases when it is cooled, more external force is required for straightening, which can easily lead to cracking or internal damage to the steel beams. Furthermore, cold straightening requires greater extrusion pressure, which increases the load on the straightening equipment. Utility Model Content

[0004] This utility model provides a straightening device for automotive steel beams, which facilitates rapid heating of the steel beams, placing the steel beams on two moving blocks, and then using the pressing blocks to press down on the arched parts for straightening, thus solving the problems in the aforementioned prior art.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A vehicle steel beam straightening device includes a base and a second lifting mechanism. The upper surface of the base is provided with a support frame and two adjustable-spaced movable blocks. The movable blocks are located inside the support frame. The opposite side walls of the support frame are respectively provided with a telescopic mechanism and a first lifting mechanism. The telescopic mechanism is connected to a conductive spiral tube. The first lifting mechanism is provided with a mechanical claw that can clamp one end of the steel beam. The first lifting mechanism can move the steel beam to align with the conductive spiral tube. The telescopic mechanism can move the conductive spiral tube onto the steel beam. The second lifting mechanism is located at the top of the support frame. The bottom of the second lifting mechanism is connected to a pressing block through a translation mechanism. The translation mechanism can move the pressing block along the length of the steel beam. The second lifting mechanism can lift and lower the pressing block to press the steel beam.

[0007] Furthermore, the telescopic mechanism includes a slide that slides through the side wall of the support frame. The slide has a U-shaped structure. A telescopic drive component is connected between the closed end of the slide and the outer side wall of the support frame. The two ends of the conductive spiral tube are respectively connected to the two ends of the slide opening.

[0008] Furthermore, the lifting mechanism includes a screw, with its two ends respectively connected to the top of the support frame and the base. The screw is connected to a motor mounted on the support frame. A lifting block is fitted together on the screw and the side wall of the support frame. The mechanical claw is located on the lifting block near the telescopic mechanism.

[0009] Furthermore, the mechanical claw includes a sleeve disposed on the lifting block, and four telescopic drive members are equally spaced on the inner wall of the sleeve, and the telescopic end of the telescopic drive member is connected to a clamping block.

[0010] Furthermore, the clamping block is provided with a force-shaping rod, which slides through the side wall of the sleeve.

[0011] Furthermore, the sleeve is rotatably mounted on the lifting block, and a toothed ring is fitted on the sleeve. The toothed ring meshes with a gear, and the gear is connected to a motor mounted on the lifting block.

[0012] Furthermore, the second lifting mechanism includes a sliding frame that slides through the top of the support frame, a telescopic drive component three connecting the top of the sliding frame and the top of the support frame, and a translation mechanism located at the bottom of the sliding frame.

[0013] Furthermore, the translation mechanism includes a second screw rod rotatably disposed at the bottom of the slide frame, the extrusion block being sleeved on the second screw rod and the slide frame, and the second screw rod being connected to a third motor disposed on the slide frame.

[0014] Furthermore, the upper surface of the base is provided with two side seats, and a bidirectional screw is rotatably provided between the two side seats. The bidirectional screw is connected to a motor four provided on the side seats. Two moving blocks are respectively sleeved on both sides of the bidirectional screw, and the lower side of the moving blocks slides across the base.

[0015] Furthermore, a aligning rod is provided on the side wall of the support frame. The aligning rod is parallel to the bidirectional screw. The upper side of the aligning rod is located near the upper surface of the moving block, and the aligning rod is located near the front side of the moving block.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] After clamping one end of the steel beam with a mechanical gripper, a lifting mechanism moves the steel beam to align with the conductive spiral tube. A telescopic mechanism then drives the conductive spiral tube to fit over the steel beam and move along it. Simultaneously, an alternating current is passed through the spiral tube, generating eddy currents inside the steel beam for rapid and uniform heating. This method provides uniform heating and is easy to operate. A translation mechanism adjusts the position of the extrusion head, and a second lifting mechanism lowers the extrusion head to apply pressure to the steel beam. Because the plasticity of the steel is significantly increased in the hot state, only a small extrusion force is needed to complete the straightening process, avoiding cracking or internal damage that may occur during cold straightening, while also reducing the load on the straightening equipment.

[0021] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0022] See Figures 1 to 2This utility model provides a straightening device for automotive steel beams, including a base 4 and a second lifting mechanism. The upper surface of the base 4 is provided with a support frame 16 and two adjustable movable blocks 1. The support frame 16 has a U-shaped structure with its opening facing downwards. The movable blocks 1 are located inside the support frame 16. A telescopic mechanism and a first lifting mechanism are respectively provided on opposite side walls of the support frame 16. The telescopic mechanism is connected to a conductive spiral tube 9, which is connected to a power source. The power source provides alternating current to the conductive spiral tube 9. The first lifting mechanism is equipped with a mechanical claw capable of gripping... One end of the steel beam is tightened, and the lifting mechanism can move the steel beam to be aligned with the central axis of the conductive spiral tube 9. The telescopic mechanism can move the conductive spiral tube 9 onto the steel beam. The lifting mechanism is located at the top of the support frame 16. The bottom of the lifting mechanism is connected to the extrusion block 11 through the translation mechanism. The bottom of the extrusion block 11 has an arc-shaped structure, which can reduce the damage to the steel beam during extrusion. The translation mechanism can move the extrusion block 11 along the length of the steel beam. The lifting mechanism can lower the extrusion block 11 to extrude the steel beam.

[0023] When straightening is required, a mechanical claw is used to clamp one end of the steel beam, causing the steel beam to deform into an upward convex state. A lifting mechanism is used to move the steel beam to the center position aligned with the center of the conductive spiral tube 9. The telescopic mechanism then moves the conductive spiral tube 9 to the right, allowing it to fit onto the steel beam and move along its length. During this movement, an alternating current is input to the spiral tube, causing eddy currents to be generated inside the steel beam, resulting in rapid and uniform heating. Preferably, the entire steel beam is heated uniformly from left to right. This method provides uniform heating and is easy to operate. The heating steel beam is lowered to near the top of the moving block 1 using the lifting mechanism 1. The mechanical claw is then released, allowing the steel beam to be supported on both sides of the moving block 1. Since the steel beam is deformed and convex upwards, the position of the extrusion head is adjusted using the translation mechanism. Once the extrusion head is aligned with the highest point of the convexity, the lifting mechanism 2 lowers the extrusion head to apply pressure to the steel beam. Because the plasticity of the steel is significantly increased when it is hot, only a small extrusion force is needed to complete the straightening operation, avoiding the cracking or internal damage that may occur during cold straightening, and reducing the load on the straightening equipment.

[0024] Preferably, the telescopic mechanism includes a slide 7 that slides horizontally through the side wall of the support frame 16. The slide 7 has a U-shaped structure. A telescopic drive component 8 is connected between the closed end of the slide 7 and the outer side wall of the support frame 16. The telescopic drive component 8 adopts an electric push rod, pneumatic telescopic rod or hydraulic telescopic rod in the prior art. The two ends of the conductive spiral tube 9 are respectively fixedly connected to the two ends of the opening of the slide 7.

[0025] When the telescopic drive component 8 shortens, it causes the slide 7 to move to the right on the left side wall of the support frame 16. The slide 7 causes the conductive spiral tube 9 to move horizontally to the right. When the telescopic drive component extends, it causes the conductive spiral tube 9 to move to the left.

[0026] Preferably, the lifting mechanism includes a screw 19, with both ends of the screw 19 being connected to the top of the support frame 16 and the base 4, respectively. The screw 19 is vertically arranged and connected to a motor 15 fixed on the support frame 16. A lifting block 20 is sleeved on both the screw 19 and the side wall of the support frame 16. The lifting block 20 is threadedly connected to the screw 19 and slidably connected to the right side wall of the support frame 16. A mechanical claw is located on the side of the lifting block 20 near the telescopic mechanism.

[0027] When the motor 15 drives the screw 19 to rotate, with the cooperation of the right side wall of the support frame 16, the screw 19 can drive the lifting block 20 to move vertically along the screw 19.

[0028] Preferably, the mechanical claw includes a sleeve 22 disposed on the left end of the lifting block 20. Four telescopic drive components 21 are fixedly disposed at equal intervals on the inner wall of the sleeve 22. The first telescopic drive component 21 adopts an electric push rod or a hydraulic telescopic rod in the prior art. The telescopic end of the second telescopic drive component 21 is fixedly connected to a clamping block 25.

[0029] When the telescopic drive component 21 extends, it will simultaneously drive the four clamping blocks 25 to move toward the center of the sleeve 22 to clamp the steel beam component, and control it to release the steel beam component when it shortens.

[0030] Preferably, the clamping block 25 is provided with a force-sharing rod 24, which slides through the side wall of the sleeve 22. The clamping block 25 can drive the force-sharing rod 24 to slide on the side wall of the sleeve 22. The force-sharing rod 24 can share the lateral force of the telescopic drive component 21, so that the design structure is reasonably stressed.

[0031] Preferably, the sleeve 22 is rotatably mounted on the lifting block 20, and a toothed ring 23 is fixedly mounted on the sleeve 22. The toothed ring 23 meshes with a gear 18, and the gear 18 is connected to a motor 17 mounted on the lifting block 20.

[0032] When the mechanical gripper clamps the steel beam, the motor 17 drives the gear 18 to rotate. The gear 18 drives the sleeve 22 to rotate through the gear ring 23, which in turn drives the steel beam to rotate. When the steel beam rotates 90 or 180 degrees, the mechanical gripper places the steel beam on the moving block 1, which facilitates the flipping of the hot steel beam to make it easier to straighten the steel beam in all directions.

[0033] Preferably, the second lifting mechanism includes a sliding frame 14 that slides through the top of the support frame 16, and a telescopic drive component 3 13 is connected between the top of the sliding frame 14 and the top of the support frame 16. The telescopic drive component 3 13 adopts an electric push rod, pneumatic telescopic rod or hydraulic telescopic rod in the prior art, and the translation mechanism is located at the bottom of the sliding frame 14.

[0034] The telescopic drive component 13 can drive the slide frame 14 to slide vertically on the top wall of the support frame 16, and the slide frame 14 can drive the extrusion block 11 to rise and fall vertically through the translation mechanism.

[0035] Preferably, the translation mechanism includes a second screw 12 that is horizontally rotatable at the bottom of the slide frame 14, the vertical projection of the second screw 12 falling on the bidirectional screw 2, an extrusion block 11 sleeved on the second screw 12 and the slide frame 14, the extrusion block 11 being threadedly connected to the second screw 12, the second screw 12 being slidably connected to the bottom wall of the slide frame 14, and the second screw 12 being connected to a third motor 10 disposed on the slide frame 14;

[0036] When the motor drives the screw 12 to rotate, the screw 12 can drive the extrusion block 11 to move horizontally left and right under the cooperation of the bottom wall of the slide frame 14, thereby adjusting the appropriate downward pressure position.

[0037] Preferably, two side seats 5 are fixedly provided on the upper surface of the base 4, and a bidirectional screw 2 is horizontally rotatably provided between the two side seats 5. The bidirectional screw 2 is rotatably connected to the side seats 5, and a motor 6 is provided on the side seats 5. Two moving blocks 1 are respectively sleeved on both sides of the bidirectional screw 2 and threadedly connected to it. The lower side of the moving blocks 1 is slidably mounted on the base 4.

[0038] When the motor 6 drives the bidirectional screw 2 to rotate on the side seat 5, the moving block 1 can only slide left and right on the base 4 and cannot rotate on the bidirectional screw 2. This allows the bidirectional screw 2 to drive the two moving blocks 1 to move closer or further apart, which is convenient for adjusting the distance between the two moving blocks 1 and is suitable for adjusting different support distances.

[0039] Preferably, a leveling rod 3 is horizontally provided on the side wall of the support frame 16. The leveling rod 3 is parallel to the bidirectional screw 2. The upper side of the leveling rod 3 is located near the upper surface of the moving block 1, and the leveling rod 3 is located near the front side of the moving block 1.

[0040] After applying pressure to straighten, use the alignment rod 3 to easily observe whether the steel beam is parallel to the alignment rod 3. When it is parallel, it means that the straightening is complete.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
