Description

Technical Field

[0001] The invention belongs to the technical field of automotive parts processing, and particularly relates to a bending device for producing environment-friendly vehicle steel plates. Background Art

[0002] As a key component of the vehicle suspension system, the manufacturing quality of vehicle leaf springs is directly related to the comfort and safety of vehicle driving. The traditional leaf spring processing process mainly includes multiple steps such as material preparation, heating, forming, cooling, and inspection. Among them, the heating process is to improve the plasticity of the material to facilitate subsequent forming operations; forming involves precise bending and ear curling of the steel plate to meet specific design requirements. The quality of each link in the entire production process needs to be strictly controlled to ensure that the final product can withstand long-term dynamic loads.

[0003] After the existing steel plate heating furnace completes heating the steel plate, it is usually necessary to first transfer the steel plate to a dedicated ear curling device for end ear curling treatment, and then move it to another bending device to complete the shaping of the shape. This production method not only requires multiple devices to complete a series of processes, but also each device needs to be equipped with corresponding operators for monitoring and adjustment, which undoubtedly increases production costs and consumption of human resources. In addition, due to the conversion between processes and material handling between devices, there may also be problems such as low production efficiency and difficulty in ensuring product quality consistency. Summary of the Invention

[0004] In order to overcome the disadvantages in the prior art that multiple devices are required to complete the ear curling and bending processes of steel plates, resulting in high production costs, large consumption of human resources, low production efficiency, and difficulty in ensuring product quality consistency, the invention provides a bending device for producing environment-friendly vehicle steel plates that can simultaneously perform ear curling and bending processing of steel plates on one device.

[0007] Furthermore, the driving assembly includes a reduction motor, a worm, a worm gear, a gear reduction group, and an annular rack. The reduction motor is installed on the sliding module. A worm is connected to the output shaft of the reduction motor. A bushing is rotatably connected to the sliding module, and a worm gear is connected to the bushing. The worm meshes with the worm gear. The other end of the swing arm is installed with an annular rack. The gear reduction group is arranged between the sliding module and the bushing and is used to transmit the rotational force of the worm gear to the annular rack.

[0008] Furthermore, a guiding mechanism is also included. The guiding mechanism includes an auxiliary hydraulic cylinder, a linkage bracket, a sliding frame, sliding blocks, positioning strips, and guiding columns. The auxiliary hydraulic cylinder is installed on the vertical frame. The linkage bracket is connected to the auxiliary hydraulic cylinder. Both ends of the linkage bracket are each connected to a sliding frame. Two sliding blocks are slidably connected inside the sliding frame. The guiding columns are connected to the sliding blocks. Eighth-shaped sliding grooves are opened on both side vertical frames. The guiding columns are slidably mated with the eighth-shaped sliding grooves.

[0009] Furthermore, a guiding rod and a limiting stop block are also included. The guiding rod is connected to the vertical frame. The limiting stop block is slidably connected to the guiding rod. A fastening bolt is provided on the limiting stop block.

[0010] Furthermore, a flared guide plate is also included. The feeding ends of both positioning strips are each connected to a flared guide plate. The distance between the two flared guide plates gradually converges from the feeding hopper end to the other end.

[0011] Furthermore, a cooling mechanism is also included.

Detailed implementation mode

[0027] The preferred technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Embodiment 1: A bending device for producing steel plates for environmental protection vehicles, as Figures 1-7As shown in the figure, it includes a base 1, a vertical frame 2, a bending mechanism 3 and an ear-rolling mechanism 4. On both the left and right sides of the top of the base 1, there are vertical frames 2 connected. Between the two vertical frames 2, there is a bending mechanism 3 installed. The bending mechanism 3 includes a main hydraulic cylinder 31, an upper fixed beam 32, a lower movable beam 33, an upper forming plate 34 and a lower forming plate 35. On the opposite sides of the two vertical frames 2, there are main hydraulic cylinders 31 installed. On the piston rods of the two main hydraulic cylinders 31, there is a lower movable beam 33 connected. Through the telescopic action of the main hydraulic cylinder 31, the lower movable beam 33 can be driven to move up and down. Between the tops of the two vertical frames 2, there is an upper fixed beam 32 fixedly connected. At the lower end of the upper fixed beam 32 and the upper end of the lower movable beam 33, there are multiple upper forming plates 34 and lower forming plates 35 connected respectively. The upper forming plates 34 and the lower forming plates 35 are arranged with a left-right offset and there is an arc-shaped gap between them up and down. The minimum distance of this arc-shaped gap is designed to be 3 millimeters larger than the thickness of the steel plate 100 to be processed. Between the front sides of the two vertical frames 2, there is an ear-rolling mechanism 4 installed. The ear-rolling mechanism 4 includes a horizontal adjustment plate 41, a linear slide rail 42, a sliding module 43, a spacing adjustment component 44, a fixed shaft 45, a swing arm 46, an ear-rolling rod 47 and a driving component 48. The two ends of the horizontal adjustment plate 41 are respectively connected to the two vertical frames 2 in a sliding manner. On the top of the horizontal adjustment plate 41, there is a linear slide rail 42 and a spacing adjustment component 44 installed. On the linear slide rail 42, there are two sliding modules 43 symmetrically arranged left and right connected in a sliding manner. The two sliding modules 43 are connected by a spacing adjustment component 44. The spacing adjustment component 44 is used to adjust the distance between the two sliding modules 43. The rear end of the sliding module 43 is connected to a fixed shaft 45. On the outside of the fixed shaft 45, there is a swing arm 46 rotatably connected. One end of the swing arm 46 is longer than the other end with the center of the fixed shaft 45 as the starting point. On the rear side of the shorter end of the swing arm 46, there is an ear-rolling rod 47 fixedly connected. The distance between the ear-rolling rod 47 and the swing arm 46 is equal to the thickness of the steel plate 100. On the sliding module 43, there is a driving component 48 installed. The driving component 48 is used to drive the swing arm 46 to rotate.

[0029] As Figure 5 shown, the spacing adjustment component 44 includes a bidirectional servo motor 441 and a lead screw 442. The bidirectional servo motor 441 is installed in the middle of the horizontal adjustment plate 41. The output shafts at both ends of the bidirectional servo motor 441 are both connected to a lead screw 442. The lead screw 442 is installed on the horizontal adjustment plate 41 through a bearing block. The lead screw 442 threadedly penetrates through the sliding module 43.

[0030] When bending the vehicle steel plate 100, the automotive steel plate 100 is calcined in a heating furnace, and the calcined steel plate 100 is placed into the gap between the upper forming plate 34 and the lower forming plate 35 by a manipulator. Since the minimum distance of the arc-shaped gap is designed to be 3 mm larger than the thickness of the steel plate 100 to be processed, it is convenient for the steel plate 100 to be placed into the arc-shaped gap. After placement, first push the transverse adjustment plate 41 backward so that the fixed shaft 45 and the coiling ear rod 47 are respectively located on the upper and lower sides of the steel plate 100. Start the bidirectional servo motor 441 to drive the lead screw 442 to rotate. The rotation of the lead screw 442 drives the two sliding modules 43 to move towards or away from each other, thereby adjusting the coiling ear position of the steel plate 100. After adjustment, turn off the bidirectional servo motor 441, and then start the driving assembly 48 to drive the swing arm 46 to rotate. The rotation of the swing arm 46 drives the coiling ear rod 47 to perform a circumferential rotational movement along the fixed shaft 45, so that the two ends of the steel plate 100 are coiled simultaneously. The steel plate 100 is closely attached to the outer wall of the fixed shaft 45. When the swing arm 46 rotates 270 degrees, the coiling of the steel plate 100 is completed. Then push the transverse adjustment plate 41 forward to reset and start the driving assembly 48 to reset. Then start the main hydraulic cylinder 31 to extend, and the lower movable beam 33 moves upward to drive the steel plate 100 to move upward through the lower forming plate 35. The lower forming plate 35 and the upper forming plate 34 cooperate to bend the steel plate 100 into an arc shape. Then start the main hydraulic cylinder 31 to shorten, and the formed steel plate 100 moves downward, and then the formed steel plate 100 is taken away by a manipulator.

[0031] As Figure 6 and Figure 7 shown, the driving assembly 48 includes a reduction motor 481, a worm 482, a worm gear 483, a gear reduction group 484, and an annular rack 485. A reduction motor 481 is installed on the sliding module 43. A worm 482 is connected to the output shaft of the reduction motor 481. A bushing is rotatably connected to the sliding module 43, and a worm gear 483 is connected to the front end of the bushing. Both the worm gear 483 and the bushing are sleeved outside the fixed shaft 45. The worm 482 meshes with the worm gear 483. An annular rack 485 is installed at the longer end of the swing arm 46. The fixed shaft 45, the worm gear 483, the bushing, and the annular rack 485 are concentrically arranged. The gear reduction group 484 is arranged between the sliding module 43 and the bushing and is used to transmit the rotational force of the worm gear 483 to the annular rack 485. The gear reduction group 484 includes a large gear and a small gear. The large gear is rotatably connected to the sliding module 43, and the small gear is fixedly connected to the bushing. The large gear meshes with the small gear and the annular rack 485 respectively. When the reduction motor 481 is driven, after the transmission of the worm 482, the worm gear 483, and the gear reduction group 484, the annular rack 485 drives the swing arm 46 to swing around the fixed shaft 45.

[0032] When the fixed shaft 45 and the lug rod 47 are respectively located on the upper and lower sides of the steel plate 100, start the reduction motor 481. The motor drives the worm 482 to rotate, and then the worm wheel 483 starts to rotate. Through the action of the worm and worm wheel mechanism, the rotational speed is reduced and the output torque is increased. The rotation of the worm wheel 483 is transmitted to the pinion through the bushing, and the pinion drives the large gear to rotate, further reducing the rotational speed and increasing the torque again. The large gear meshes with the annular rack 485, causing the annular rack 485 to rotate accordingly. The rotation of the annular rack 485 drives the swing arm 46 to rotate around the fixed shaft 45. Since the swing arm 46 is designed with one end longer than the other end, and the shorter end is fixedly connected to the lug rod 47 at the rear side, when the annular rack 485 acts on the longer end of the swing arm 46, it can more labor-savingly make the lug rod 47 rotate axially around the fixed shaft 45. This design utilizes the lever principle, making the annular rack 485 more efficient when driving the swing arm 46, thus achieving a more labor-saving operation effect.

[0033] Embodiment 2: On the basis of Embodiment 1, as Figure 1 , Figure 2 , Figure 8 and Figure 9 shown, it further includes a guiding mechanism 5. The guiding mechanism 5 includes an auxiliary hydraulic cylinder 51, a linkage bracket 52, a sliding frame 53, a sliding block 54, a positioning strip 55 and a guiding column 56. Auxiliary hydraulic cylinders 51 are installed at the lower parts of the two vertical frames 2. Linkage brackets 52 are connected to the piston rods of the two auxiliary hydraulic cylinders 51. Both ends of the top of the linkage bracket 52 are connected with sliding frames 53. Two sliding blocks 54 are slidably connected in each sliding frame 53. A guiding column 56 is connected to each sliding block 54. E-shaped sliding grooves 21 are formed on both sides of the vertical frames 2. The upper ends of the E-shaped sliding grooves 21 are connected through a linear hole. The guiding column 56 is slidably matched with the E-shaped sliding groove 21. Positioning strips 55 are embeddedly connected to the sliding blocks 54 and the guiding columns 56. The cross-section of the positioning strip 55 is L-shaped. The minimum distance between the two positioning strips 55 is less than the width of the steel plate 100.

[0034] Furthermore, as Figure 8 shown, it further includes a flared guide plate 57. Feeding ends on the left sides of the two positioning strips 55 are both connected with flared guide plates 57. The distance between the two flared guide plates 57 gradually converges from left to right.

[0035] Furthermore, as Figure 4 shown, it further includes a guiding rod 12 and a limiting block 13. A guiding rod 12 is horizontally connected to the left side of the right vertical frame 2. A limiting block 13 is slidably connected to the guiding rod 12. The limiting block 13 is located between the two positioning strips 55. A fastening bolt is provided on the limiting block 13.

[0036] The steel plate 100 is clamped by a manipulator and inserted between the two bell-mouth guide plates 57 from left to right. The steel plate 100 moves to the right through the straight hole. Since the distance between the two bell-mouth guide plates 57 gradually gathers from left to right, it is more convenient to insert the bell-mouth guide plates 57. Since the cross-section of the positioning strip 55 is L-shaped, the steel plate 100 can be supported by the horizontal part of the positioning strip 55. The steel plate 100 is guided by the two positioning strips 55, so that the steel plate 100 can be accurately placed between the upper forming plate 34 and the lower forming plate 35. Loosen the fastening bolts on the limit stopper 13, pull the limit stopper 13 to move horizontally on the guide rod 12, and after adjustment, tighten the fastening bolts. When the end of the steel plate 100 abuts against the limit stopper 13, the steel plate 100 no longer moves to the right, thereby adjusting the steel plate 100 on the positioning strip 5 5, so that the steel plate 100 is accurately in the position to be bent. When the steel plate 100 needs to be rolled and bent, the auxiliary hydraulic cylinder 51 is started to extend, and the sliding frame 53 is driven to move downward through the linkage bracket 52, and the guide column 56 moves downward. Under the action of the eight-shaped slide groove 21, the two guide columns 56 move downward while moving away from each other, and the slider 54 slides in the sliding frame 53. When the positioning bar 55 moves to a position lower than the rolling ear rod 47, the positioning bar 55 no longer supports the steel plate 100, and the steel plate 100 falls on the top of the lower forming plate 35, pushing the lateral adjustment plate 41 to move backward, and the steel plate 100 is located between the rolling ear rod 47 and the fixed shaft 45. Then, the steel plate 100 is bent and rolled. The guide mechanism 5 can conveniently guide the steel plate 100 to avoid the steel plate 100 from deflecting.

[0037] like Figure 3 and Figure 5 As shown, a linkage mechanism 7 is also included, and the linkage mechanism 7 includes a linkage connecting block 71, a transmission connecting rod 73 and a sliding shaft 74. The middle part of the linkage bracket 52 is connected to the linkage connecting block 71, and an oblique guide groove 72 is opened on the linkage connecting block 71. The oblique guide groove 72 is L-shaped, and the angle of the oblique guide groove 72 is 135 degrees. The bottom of the lateral adjustment plate 41 is connected to a transmission connecting rod 73, and the lower end of the transmission connecting rod 73 is connected to a sliding shaft 74, and the sliding shaft 74 is located in the oblique guide groove 72. When the linkage bracket 52 moves downward, the sliding shaft 74 is driven to slide backward through the oblique guide groove 72, so that the ear rolling mechanism 4 moves toward the direction of the steel plate 100.

[0038] When the linkage bracket 52 moves downward, it drives the sliding shaft 74 to move backward through the inclined guide groove 72, and then drives the lateral adjustment plate 41 to move backward through the transmission connecting rod 73; conversely, when the linkage bracket 52 moves upward, it drives the sliding shaft 74 to move forward through the inclined guide groove 72, and then drives the lateral adjustment plate 41 to move forward through the transmission connecting rod 73. In this way, the following actions can be achieved: when the positioning strips 55 move downward and away from each other, the fixed shaft 45 and the ear rod 47 are inserted outside the steel plate 100; when the positioning strips 55 move upward and close to each other, the fixed shaft 45 and the ear rod 47 move away from the steel plate 100, simplifying the operation steps and making the actions more coherent, thus improving the work efficiency.

[0039] Embodiment 3: On the basis of Embodiment 2, as Figure 1 and Figure 10 shown, it further includes a cooling mechanism 6. The cooling mechanism 6 includes a circulating water tank 61, a high-pressure water pump 62, a water outlet pipe 64, a nozzle 65 and a flexible connecting pipe 66. The circulating water tank 61 is installed inside the base 1, the high-pressure water pump 62 is installed on the front side of the base 1, grooves 63 are opened in the middle of the upper fixed beam 32 and the lower movable beam 33, the water outlet pipe 64 is connected inside the grooves 63, nozzles 65 are connected at intervals on the opposite sides of the two water outlet pipes 64, and the nozzles 65 are evenly distributed between two adjacent upper forming plates 34 and between two adjacent lower forming plates 35. The water outlet end and the water suction end of the high-pressure water pump 62 are both connected with flexible connecting pipes 66. The flexible connecting pipes 66 at the water outlet end of the high-pressure water pump 62 are respectively connected with the two water outlet pipes 64, and the flexible connecting pipe 66 at the water suction end of the high-pressure water pump 62 sequentially penetrates through the base 1 and the circulating water tank 61.

[0040] Further, as Figure 10 described, it further includes a filter 67. The filter 67 is connected to the flexible connecting pipe 66 at the water suction end of the high-pressure water pump 62, and the filter 67 is located inside the circulating water tank 61.

[0041] After the main hydraulic cylinder 31 drives the upper forming plate 34 and the lower forming plate 35 to complete the forming process on the steel plate 100, the high-pressure water pump 62 is started to draw water from the circulating water tank 61 through the flexible connecting pipe 66. Then the water flow passes through the water outlet pipe 64 and acts on the surface of the steel plate 100 in the form of spraying by the nozzles 65 to achieve the effect of cooling and shaping. The sprayed water finally flows back to the circulating water tank 61 for recycling; and impurities are removed through the filter 67 to prevent them from entering the flexible connecting pipe 66 and the high-pressure water pump 62 from the water suction end and causing blockage, ensuring the stable operation of this device.

[0042] Embodiment 4: On the basis of Embodiment 3, as Figure 1 and Figure 2As shown in the figure, it further includes a cylinder 8, a connecting member 9, an arc-shaped pusher plate 10 and an inclined guide plate 11. A cylinder 8 is installed at the top of the upper fixed beam 32. A connecting member 9 is connected to the telescopic rod of the cylinder 8. The lower end of the connecting member 9 is connected to an arc-shaped pusher plate 10. The arc-shaped pusher plate 10 and the connecting member 9 are both located on the front side of the upper fixed beam 32. The radian of the arc-shaped pusher plate 10 is the same as that of the formed steel plate 100. The upper rear part of the base 1 is connected to an inclined guide plate 11. The upper end of the inclined guide plate 11 is lower than the lower end of the arc-shaped pusher plate 10.

[0043] After the steel plate 100 is formed, start to shorten the main hydraulic cylinder 31 to align the formed steel plate 100 with the arc-shaped pusher plate 10. Then start the cylinder 8. The cylinder 8 drives the arc-shaped pusher plate 10 to move backward through the connecting member 9, pushing the formed steel plate 100 backward so that it falls on the inclined guide plate 11 and is then led out through the inclined guide plate 11. This method eliminates the need to use a manipulator to remove the steel plate 100, improving the removal efficiency.
