Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, and in particular to an automotive stabilizer bar bending and forming equipment. Background Technology

[0002] A stabilizer bar, also called an anti-roll bar, functions to reduce body roll during cornering and improve ride comfort. Stabilizer bars are found in the front suspension of most vehicles, from small cars to heavy-duty trucks. Due to the need to avoid interference with surrounding components during design, stabilizer bars come in various forms, but are generally integrated with a torsion bar. Furthermore, the material cross-section can be solid or hollow, with hollow materials, which are advantageous for weight reduction, increasingly being used.

[0003] There are many shapes of existing car stabilizer bars, and each shape requires specialized equipment to be fully formed, making it difficult to meet the production needs of different car stabilizer bars. Summary of the Invention

[0004] The purpose of this invention is to provide an automotive stabilizer bar bending and forming equipment, which can achieve the bending and forming of automotive stabilizer bars of different sizes.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an automotive stabilizer bar bending and forming device, comprising a support frame, processing frames sliding on both sides of the support frame, a processing table and a positioning cylinder located above the processing table fixedly mounted on each of the processing frames, and a connecting plate rotatably mounted on each of the processing frames, the positioning cylinders being located between the connecting plates, a positioning block sliding on the processing frame being fixedly attached to the output end of the positioning cylinder, a forming cylinder being fixedly mounted on the connecting plate, a connecting frame sliding on the connecting plate being fixedly attached to the output end of the forming cylinder, a forming wheel rotating at the end of the connecting frame away from the forming cylinder, and an adjustment mechanism for driving the processing frames on both sides to slide mirror images on the support frame.

[0006] By adopting the above technical solution, the heated, red-hot stabilizer bar is sent to the processing table. The positioning cylinders on both sides are activated to drive the positioning blocks on both sides to descend and press the stabilizer bar tightly. Then, the forming cylinder is activated to drive the connecting frames and forming wheels on both sides to descend and bend the two ends of the stabilizer bar into a predetermined shape. After bending, the workpiece is still in a high-temperature state. The adjustment mechanism is activated to drive the processing frames on both sides to slide mirror-slide along the support frame to adjust the position of the processing frames, so that the processing frames can support stabilizer bars of different lengths. There is no need to equip each stabilizer bar of a specific length with special equipment, which greatly reduces equipment investment costs and workshop space occupation.

[0007] A further configuration of the present invention is as follows: the adjustment mechanism includes an adjustment screw with reverse threads at both ends rotatably connected to the support frame and an adjustment motor fixedly installed on the support frame to drive the adjustment screw to rotate; the support frame is fixedly provided with first slide rails at the top and bottom; and the processing frame is fixedly provided with a fixing block threaded to the adjustment screw and a first slider sliding on the first slide rail on the side away from the processing table.

[0008] By adopting the above technical solution, the adjustment motor is started, which drives the adjustment screw to rotate. In turn, the adjustment screw drives the two processing frames on both sides to move in a mirror image to adjust the position of the processing frame, so that it can support the stabilizing rods of different sizes.

[0009] A further configuration of the present invention is as follows: a second slide rail is provided on the processing frame, a third slide rail is provided on the connecting plate, a second slider that slides on the second slide rail is fixed on the positioning block, and a third slider that slides on the third slide rail is fixed on the connecting frame.

[0010] By adopting the above technical solution, when the positioning cylinder is started, the piston rod end pushes the positioning block and the second slider to lift and lower on the second slide rail to achieve pressing and positioning or loosening and unloading of the stabilizer rod. The forming cylinder pushes the connecting frame and the third slider to lift and lower on the third slide rail to achieve bending and forming work at both ends of the stabilizer rod.

[0011] A further feature of the present invention is that: the processing frame is rotatably connected to a positioning cam, the forming wheels on both sides are located between the positioning cams on both sides, a positioning plate is fixed to the positioning cam circumferentially along its outer wall, and a positioning mechanism for driving the positioning cam to rotate is provided on the processing frame.

[0012] By adopting the above technical solution, before the positioning cylinder pushes the positioning block to press and position the stabilizer bar, the positioning mechanism drives the positioning cams on both sides to rotate synchronously in opposite directions. Then, the positioning plates on both sides rotate synchronously to push the stabilizer bar, so that the stabilizer bar is centered on the processing table. This ensures that for the same model of stabilizer bar, the support point and centering state are the same every time, so that the stabilizer bar bends symmetrically from left to right, ensuring the bending geometric accuracy.

[0013] A further configuration of the present invention is as follows: one side of the processing frame has a through hole located between the positioning cylinder and the processing table; the positioning mechanism includes a fixed rod fixed to the positioning block and passing through the through hole; a rack is fixed to one end of the fixed rod away from the positioning block; a first telescopic rod is rotatably connected between the two sides of the processing frame; a gear meshing with the rack is fixed to the body of the first telescopic rod; and first bevel teeth are fixed to both ends of the first telescopic rod; the positioning cam is fixed to a transmission shaft rotatably connected to the processing frame; and a second bevel tooth meshing with the first bevel tooth is fixed to one end of the transmission shaft away from the positioning cam.

[0014] By adopting the above technical solution, during the period when the positioning cylinder pushes the positioning block down to prepare to press the stabilizer bar, the positioning block drives the fixed bar to descend in the through hole, thereby the fixed bar drives the rack to descend. When the rack meshes with the gear, the gear rotates, which in turn drives the first telescopic rod to rotate and the first bevel teeth at both ends to rotate. The first bevel teeth drive the second bevel teeth to rotate. The rotation of the second bevel teeth, the transmission shaft and the positioning cam realizes the centering positioning of the stabilizer bar. The centering positioning action of the stabilizer bar is integrated into the pressing action of the stabilizer bar, which is used to shorten the overall working time and ensure that the stabilizer bar completes all bending actions before cooling down to below the recrystallization temperature.

[0015] A further configuration of the present invention is as follows: the connecting plate is fixed with an adjusting shaft that rotates on the processing frame; a worm gear is fixed at one end of the adjusting shaft away from the connecting plate; a second telescopic rod is rotatably connected between the two processing frames; worms meshing with the worm gear are fixed at both ends of the second telescopic rod; the threads on the worms at both ends are reversed; and a drive motor for driving one end of the worm to rotate is fixedly installed on one side of the processing frame.

[0016] By adopting the above technical solution, the drive motor is started, which drives the worm to rotate. Then, the two worms on the coaxial ends and the second telescopic rod in the middle rotate synchronously. The worm with reverse threads at both ends drives the worm wheel that meshes with it to rotate in the opposite direction. Then, the adjusting shafts on both sides, the connecting plate, the forming cylinder and the forming wheel rotate in the opposite direction on the processing frame to adjust the angle between them and the processing table. Thus, it is possible to bend and process different shapes of car stabilizer bars as needed, maintain the left and right symmetrical bending of the stabilizer bar, and have a wider range of applications.

[0017] A further configuration of the present invention is as follows: both the first telescopic rod and the second telescopic rod include a sleeve rod with an inner cavity and a slide rod that slides out of the inner cavity of the sleeve rod. The inner cavity wall of the sleeve rod is provided with a plurality of keyways, and the outer wall of the slide rod is fixed with a plurality of keys that slide in the keyways and cooperate with the keyways along the circumferential direction.

[0018] By adopting the above technical solution, the slide rod and the sleeve rod are rotatably connected to the processing frames on both sides. When the processing frames on both sides move relative to each other under the drive of the adjustment mechanism, the end of the slide rod slides in the inner cavity of the sleeve rod, so that the overall length of the first telescopic rod or the second telescopic rod is extended or shortened, maintaining the connection of the first bevel teeth at both ends or the worm gears at both ends. When one end of the first bevel tooth or the worm gear rotates, the slide rod and the key drive the keyway and the sleeve rod to rotate synchronously, thereby causing the first bevel teeth at both ends or the worm gears at both ends to rotate synchronously, realizing the reverse rotation of the positioning cams on both sides or the reverse angle adjustment of the forming wheels on both sides.

[0019] A further feature of the present invention is that the positioning cam is provided with an adjustment hole through which the end of the transmission shaft passes, and the end of the transmission shaft is fixed with a limiting plate and a mounting plate located on both sides of the positioning cam and abutting against the end faces of both sides of the positioning cam, and the mounting plate is threadedly connected with a mounting bolt extending into the positioning cam.

[0020] By adopting the above technical solution, the position of the positioning cam relative to the drive shaft can be adjusted by installing bolts, and the position of the positioning cam can be adjusted according to the size of the stabilizer bar.

[0021] A further feature of the present invention is that the bottom end of the positioning block is provided with a first limiting groove, and the outer wall of the forming wheel is provided with a second limiting groove in the circumferential direction.

[0022] By adopting the above technical solution, the first limiting groove increases the contact area between the positioning block and the stabilizer bar, so that the positioning block can better press the stabilizer bar, and the second limiting groove is used for the forming wheel to better push the stabilizer bar, so that the stabilizer bar can be bent and shaped.

[0023] A further feature of the present invention is that a bracket is fixed to the side of the second slider away from the forming wheel, and a support plate is fixed to the bottom end of the bracket.

[0024] By adopting the above technical solution, after the bending operation is completed, the forming cylinder first drives the forming wheel to rise and return, and then the positioning cylinder drives the positioning block and the second slider to rise and return. During the rise of the second slider, the bracket drives the support plate to rise, so that the support plate rises from below the processing table to the processing table and lifts the stabilizing rod, so that the stabilizing rod is detached from the processing table, which is conducive to the subsequent unloading work of the operator and avoids the situation that the stabilizing rod may bite the processing table due to cooling and shrinkage, which may affect the unloading.

[0025] The beneficial effects of this invention are:

[0026] 1. The adjustment mechanism can drive the processing frames on both sides to slide and adjust the position of the processing frames along the support frame, so that the processing frames can support the stabilizer bars of different lengths. There is no need to equip each stabilizer bar of a specific length with special equipment, which greatly reduces the equipment investment cost and workshop space occupation.

[0027] 2. The positioning mechanism can drive the positioning cams on both sides to rotate synchronously in opposite directions, thereby rotating the positioning plates on both sides to push the stabilizer bar synchronously, so that the stabilizer bar is centered on the processing table, ensuring that for the same model of stabilizer bar, the support point and centering state are the same every time, so that the stabilizer bar bends symmetrically from left to right, ensuring bending geometric accuracy.

[0028] 3. Integrate the centering and positioning action of the stabilizer bar into the stabilizer bar clamping action to shorten the overall working time and ensure that the stabilizer bar completes all bending actions before cooling down to below the recrystallization temperature;

[0029] 4. By driving the motor, worm gear, second telescopic rod, and worm wheel, the two side adjusting shafts, connecting plates, forming cylinders, and forming wheels rotate in opposite directions on the processing frame to adjust the angle between them and the processing table. This allows for the bending and processing of different shapes of car stabilizer bars as needed, maintaining the left and right symmetrical bending of the stabilizer bar, and thus expanding its application range.

[0030] 5. The position of the positioning cam relative to the drive shaft can be adjusted by mounting bolts, and the position of the positioning cam can be adjusted according to the size of the stabilizer bar;

[0031] 6. The pallet can rise from below the processing table to the processing table to lift the stabilizing bar, so that the stabilizing bar is detached from the processing table, which is beneficial for the operator to unload the material later and avoids the situation where the stabilizing bar may get stuck on the processing table due to cooling and shrinkage, which may affect the unloading.

[0038] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] Example 1: A vehicle stabilizer bar bending and forming equipment, such as... Figure 1 , 3As shown, the system includes a support frame 1, with processing frames 2 sliding on both sides of the support frame 1. Each processing frame 2 has a processing table 3 and a positioning cylinder 4 fixedly mounted on it. A connecting plate 5 is rotatably mounted on each processing frame 2. The positioning cylinder 4 is located between the connecting plates 5. A positioning block 6, which slides on the processing frame 2, is fixed to the output end of the positioning cylinder 4. A forming cylinder 7 is fixedly mounted on the connecting plate 5. A connecting frame 10, which slides on the connecting plate 5, is fixed to the output end of the forming cylinder 7. A forming wheel 8 rotates on the end of the connecting frame 10 away from the forming cylinder 7. An adjustment mechanism 9 is installed on the support frame 1 to drive the mirror sliding of the processing frames 2. In use, a heated, red-hot stabilizing rod is placed on the processing table 3. The positioning cylinders 4 on both sides are activated, causing the positioning blocks 6 to descend and press the stabilizing rod. Then, the forming... The forming cylinder 7 drives the two connecting frames 10 and forming wheels 8 to descend. The two forming wheels 8 contact the two ends of the stabilizer rod respectively, bending the two ends of the stabilizer rod into a predetermined shape. After bending, the forming cylinder 7 first drives the forming wheels 8 to rise back, and then the positioning cylinder 4 drives the positioning block 6 to rise back. The workpiece is still in a high temperature state. The operator uses tools to remove the stabilizer rod from the processing table 3 and quickly transfers the workpiece to the quenching tank or spray device for rapid cooling by immersion or spraying quenching oil. In use, the adjustment mechanism 9 is activated to drive the two processing frames 2 to slide mirror-slide along the support frame 1 to adjust the position of the processing frame 2. This allows the processing frame 2 to support stabilizer rods of different lengths, eliminating the need for special equipment for each specific length of stabilizer rod, greatly reducing equipment investment costs and workshop space occupation.

[0040] like Figure 3 As shown, the adjustment mechanism 9 includes an adjustment screw 91 with reverse threads at both ends rotatably connected to the support frame 1 and an adjustment motor 92 fixedly installed on the support frame 1 to drive the adjustment screw 91 to rotate. The support frame 1 is fixedly equipped with a first slide rail 93 at the top and bottom. The processing frame 2 is fixed with a fixing block threaded to the adjustment screw 91 and a first slider 94 sliding on the first slide rail 93 on the side away from the processing table 3. By starting the adjustment motor 92, the adjustment motor 92 drives the adjustment screw 91 to rotate, and then the rotation of the adjustment screw 91 drives the two processing frames 2 to move in a mirror image. The first slider 94 slides on the first slide rail 93 to guide and adjust the position of the processing frame 2 so that it can support stabilizer bars of different sizes.

[0041] As a further feature of the present invention, the processing frame 2 is provided with a second slide rail 11, the connecting plate 5 is provided with a third slide rail 12, the positioning block 6 is fixed with a second slider 13 that slides on the second slide rail 11, and the connecting frame 10 is fixed with a third slider 14 that slides on the third slide rail 12. When the positioning cylinder 4 is started, the piston rod end pushes the positioning block 6 and the second slider 13 to rise and fall on the second slide rail 11 to achieve pressing and positioning or loosening and unloading of the stabilizing rod. The forming cylinder 7 pushes the connecting frame 10 and the third slider 14 to rise and fall on the third slide rail 12 to achieve bending and forming work at both ends of the stabilizing rod.

[0042] like Figure 1 , 2 As shown, the processing frame 2 is rotatably connected to a positioning cam 15, and the two forming wheels 8 are located between the two positioning cams 15. The positioning cam 15 is fixed with a positioning plate 16 along its outer wall circumferentially. The processing frame 2 is provided with a positioning mechanism 17 that drives the positioning cam 15 to rotate. Before the positioning cylinder 4 pushes the positioning block 6 to press the stabilizing rod into position, the positioning mechanism 17 drives the two positioning cams 15 to rotate synchronously in opposite directions. Then, the two positioning plates 16 rotate synchronously to push the stabilizing rod, so that the stabilizing rod is centered on the processing table 3. This ensures that for the same model of stabilizing rod, the support point and centering state are the same every time, so that the stabilizing rod bends symmetrically from left to right, ensuring the bending geometric accuracy.

[0043] like Figure 3As shown, one side of the processing frame 2 has a through hole 18 located between the positioning cylinder 4 and the processing table 3. The positioning mechanism 17 includes a fixed rod 171 fixed to the positioning block 6 and passing through the through hole 18. A rack 172 is fixed to the end of the fixed rod 171 away from the positioning block 6. A first telescopic rod 173 is rotatably connected between the two sides of the processing frame 2. A gear 174 meshing with the rack 172 is fixed to the body of the first telescopic rod 173, and first bevel teeth 175 are fixed to both ends of the first telescopic rod 173. A transmission shaft 176 rotatably connected to the processing frame 2 is fixed to the positioning cam 15. A second bevel tooth 177 meshing with the first bevel tooth 175 is fixed to the end of the transmission shaft 176 away from the positioning cam 15. During the period when the positioning cylinder 4 pushes the positioning block 6 down to prepare to press the stabilizing rod, the positioning block 6 drives the fixed rod 171 to... The through hole 18 descends, causing the fixed rod 171 to drive the rack 172 to descend. When the rack 172 meshes with the gear 174, the gear 174 rotates, which in turn drives the first telescopic rod 173 to rotate and the first bevel teeth 175 at both ends to rotate. The first bevel teeth 175 drive the second bevel teeth 177 to rotate. The rotation of the second bevel teeth 177, the drive shaft 176, and the positioning cam 15 achieves centering of the stabilizer rod. The centering action of the stabilizer rod is integrated into the clamping action of the stabilizer rod to shorten the overall working time and ensure that the stabilizer rod completes all bending actions before cooling down to below the recrystallization temperature. After the stabilizer rod is centered, the positioning cylinder 4 continuously pushes the positioning block 6 downward until the positioning block 6 clamps the stabilizer rod. During this period, the rack 172 no longer meshes with the gear 174, and the positioning cam 15 no longer rotates.

[0044] like Figure 3 As shown, the connecting plate 5 is fixed with an adjusting shaft 19 that rotates on the processing frame 2. A worm gear 20 is fixed at the end of the adjusting shaft 19 away from the connecting plate 5. A second telescopic rod 21 is rotatably connected between the two processing frames 2. Worms 22 that mesh with the worm gear 20 are fixed at both ends of the second telescopic rod 21. The threads on the worms 22 at both ends are reversed. A drive motor 23 that drives one end of the worm 22 to rotate is fixedly installed on one side of the processing frame 2. When the forming wheel 8 is above the processing table 3, the drive motor 23 is started, causing the drive motor 23 to drive the worm 22 to rotate. Then, the two worms 22 at both ends and the second telescopic rod 21 in the middle rotate synchronously. The worms 22 with reversed threads at both ends drive the worm gear 20 that meshes with them to rotate in the opposite direction. Then, the two adjusting shafts 19, connecting plate 5, forming cylinder 7 and forming wheel 8 rotate in the opposite direction on the processing frame 2 to adjust the angle between them and the processing table 3. This allows for the bending and processing of different shaped car stabilizer bars as needed, maintaining the left and right symmetrical bending of the stabilizer bar, and expanding its application range.

[0045] like Figure 4As shown, both the first telescopic rod 173 and the second telescopic rod 21 include a sleeve rod 24 with an inner cavity and a slide rod 25 that slides out of the inner cavity of the sleeve rod 24. The inner wall of the sleeve rod 24 is provided with multiple key 26 grooves. The outer wall of the slide rod 25 is fixed with multiple keys 26 that slide in the key 26 grooves and cooperate with the key 26 grooves. The slide rod 25 and the sleeve rod 24 are rotatably connected to the processing frames 2 on both sides. When the processing frames 2 on both sides move relative to each other under the drive of the adjustment mechanism 9, the end of the slide rod 25 slides in the inner cavity of the sleeve rod 24, so that the overall length of the first telescopic rod 173 or the second telescopic rod 21 is extended or shortened, maintaining the connection of the first bevel teeth 175 at both ends or the worm gears 22 at both ends. When one end of the first bevel tooth 175 or the worm gear 22 rotates, the slide rod 25 and the key drive the key 26 groove and the sleeve rod 24 to rotate synchronously, thereby causing the first bevel teeth 175 at both ends or the worm gears 22 at both ends to rotate synchronously, realizing the reverse rotation of the positioning cams 15 on both sides or the reverse angle adjustment of the forming wheels 8 on both sides.

[0046] As a further feature of the present invention, the positioning cam 15 is provided with an adjustment hole 27 through which the end of the drive shaft 176 passes. The end of the drive shaft 176 is fixed with a limiting plate and a mounting plate 28 located on both sides of the positioning cam 15 and abutting against the end faces of the positioning cam 15. The mounting plate 28 is threadedly connected with a mounting bolt 29 extending into the positioning cam 15. The positioning cam 15 is pressed between the limiting plate and the mounting plate 28. The position of the positioning cam 15 relative to the drive shaft 176 can be adjusted by the mounting bolt 29, and the position of the positioning cam 15 can be adjusted according to the size of the stabilizer bar.

[0047] As a further feature of the present invention, the bottom end of the positioning block 6 is provided with a first limiting groove 30, and the outer wall of the forming wheel 8 is provided with a second limiting groove 31. The first limiting groove 30 increases the contact area between the positioning block 6 and the stabilizing rod, so that the positioning block 6 can better press the stabilizing rod. The second limiting groove 31 is used for the forming wheel 8 to better push the stabilizing rod, so that the stabilizing rod is bent and shaped.

[0048] As a further feature of the present invention, a bracket 32 ​​is fixed to the side of the second slider 13 away from the forming wheel 8. A support plate 33 is fixed to the bottom end of the bracket 32. The support plate 33 may be provided with a groove to facilitate the lifting of the stabilizing rod. When the stabilizing rod is placed on the processing table 3, the positioning block 6 is located above the processing table 3, while the support plate 33 is located below the processing table 3. After the bending operation is completed, the forming cylinder 7 first drives the forming wheel 8 to rise and return, and then the positioning cylinder 4 drives the positioning block 6 and the second slider 13 to rise and return. During the rising process of the second slider 13, the support plate 33 is driven to rise through the bracket 32, so that the support plate 33 rises from below the processing table 3 to the processing table 3 to lift the stabilizing rod, so that the stabilizing rod is detached from the processing table 3. This facilitates the subsequent unloading work of the operator and avoids the situation where the stabilizing rod may bite the processing table 3 due to cooling and shrinkage, which may affect the unloading. After completion, the positioning cylinder 4 drives the second slider 13, bracket 32 ​​and support plate 33 to descend a short distance until the support plate 33 is below the processing table 3 (at this time, gear 174 is not meshed with gear 174). Then, the next stabilizer bar to be processed is placed on the processing table 3 for bending. When bending is performed again, the positioning cylinders on both sides are activated first to drive the positioning blocks on both sides 6 to descend and press the stabilizer bar tightly (during this period, the rack 172 meshes with the gear 174, driving the first telescopic rod 173 and the first bevel gear 175 to rotate. The first bevel gear 175 drives the second bevel gear 177 to rotate. The second bevel gear 177, the drive shaft 176 and the positioning cam 15 rotate to center the stabilizer bar). Then, the forming cylinder 7 is activated to drive the connecting brackets on both sides 10 and the forming wheel 8 to descend and bend the two ends of the stabilizer bar to bend it into the predetermined shape.
