[0001] The invention belongs to the technical field of automobile parts processing, and in particular relates to a bending device for producing environmentally friendly vehicle steel plates. Background Art

[0002] As a key component of the automotive suspension system, the manufacturing quality of leaf springs directly impacts vehicle comfort and safety. Traditional leaf spring processing involves multiple steps, including material preparation, heating, forming, cooling, and testing. Heating enhances the material's plasticity for subsequent forming operations, while forming involves precisely bending and curling the steel sheets to meet specific design requirements. The entire production process requires strict quality control at every stage to ensure the final product can withstand long-term dynamic loads.

[0003] After heating the steel plate in an existing heating furnace, the plate is typically transferred to a specialized ear-rolling machine for end-earing, and then moved to another bending machine to complete the shaping process. This production method not only requires the use of multiple machines to complete a series of processes, but also requires a dedicated operator to monitor and adjust each machine, which undoubtedly increases production costs and human resources. In addition, the transition between processes and the handling of materials between equipment can lead to low production efficiency and difficulty in ensuring consistent product quality.

DETAILED DESCRIPTION

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

[0028] Example 1: A bending device for producing environmentally friendly vehicle steel plates, such as Figure 1-Figure 7As shown, it includes a base 1, a stand 2, a bending mechanism 3 and an ear-rolling mechanism 4. The stand 2 is connected to the left and right sides of the top of the base 1. The bending mechanism 3 is installed between the two stands 2. 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. The main hydraulic cylinder 31 is installed on the opposite side of the two stands 2. The piston rods of the two main hydraulic cylinders 31 are connected to the lower movable beam 33. Through the telescopic action of the main hydraulic cylinder 31, the bending mechanism 3 can be To drive the lower movable beam 33 to move up and down, an upper fixed beam 32 is fixed between the tops of the two upright frames 2, and the lower end of the upper fixed beam 32 and the upper end of the lower movable beam 33 are respectively connected to multiple upper forming plates 34 and lower forming plates 35. The upper forming plates 34 and the lower forming plates 35 are staggered left and right and an arc-shaped gap is left between the upper and lower parts. The minimum spacing of the arc-shaped gap is designed to be 3 mm larger than the thickness of the steel plate 100 to be processed. A rolling ear mechanism 4 is installed between the front sides of the two upright frames 2. The rolling ear mechanism 4 includes a horizontal The two ends of the lateral adjustment plate 41 are slidably connected to the two side frames 2, and the linear slide rail 42 and the spacing adjustment assembly 44 are installed on the top of the lateral adjustment plate 41. The linear slide rail 42 is slidably connected to the two left and right symmetrical sliding modules 43. The two sliding modules 43 are connected through the spacing adjustment assembly 44. The spacing adjustment assembly 44 is used to adjust the distance between the two sliding modules 43. The rear end of the sliding module 43 is connected to the fixed shaft 45, and the outer side of the fixed shaft 45 is rotatably connected to the swing arm 46. The swing arm 46 takes the center of the fixed shaft 45 as the starting point, and one end is longer than the other end. The rear side of the shorter end of the swing arm 46 is fixed with a rolling ear rod 47. The distance between the rolling ear rod 47 and the swing arm 46 is equal to the thickness of the steel plate 100. The driving assembly 48 is installed on the sliding module 43, and the driving assembly 48 is used to drive the swing arm 46 to rotate.

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

[0030] When bending the vehicle steel plate 100, the vehicle steel plate 100 is calcined in a heating furnace and placed into the gap between the upper forming plate 34 and the lower forming plate 35 by a manipulator. Since the minimum spacing 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 easy to place the steel plate 100 into the arc-shaped gap. After placing it, first push the transverse adjustment plate 41 backward so that the fixed shaft 45 and the ear rod 47 are located on the upper and lower sides of the steel plate 100 respectively, and start the bidirectional servo motor 441 to drive the screw rod 442. The screw rod 442 rotates, driving the two sliding modules 43 to move toward or away from each other, thereby adjusting the ear position of the steel plate 100. After adjustment, the bidirectional servo motor 441 is turned off, and the drive assembly 48 is activated to drive the swing arm 46 to rotate. The swing arm 46 drives the ear rod 47 to rotate circumferentially along the fixed shaft 45, so that the two ends of the steel plate 100 are synchronously ear-wound, and the steel plate 100 is tightly attached to the outer wall of the fixed shaft 45. When the swing arm 46 rotates 270 degrees, the steel plate 100 is completely ear-wound, and the lateral adjustment plate 41 is pushed forward to return to its original position, and the drive assembly 48 is activated to return to its original position. The main hydraulic cylinder 31 is then activated to extend, and the lower movable beam 33 moves upward through the lower forming plate 35, driving the steel plate 100 upward. The lower forming plate 35 and the upper forming plate 34 cooperate to bend the steel plate 100 into an arc. The main hydraulic cylinder 31 is then activated to shorten, and the formed steel plate 100 moves downward. The formed steel plate 100 can then be removed by the robot.

[0031] like Figure 6 and Figure 7 As shown, the drive assembly 48 includes a reduction motor 481, a worm 482, a worm wheel 483, a gear reduction group 484 and an annular rack 485. The reduction motor 481 is installed on the sliding module 43. The output shaft of the reduction motor 481 is connected to the worm 482. The sliding module 43 is rotatably connected to a sleeve. The front end of the sleeve is connected to the worm wheel 483. The worm wheel 483 and the sleeve are both sleeved on the outside of the fixed shaft 45. The worm 482 is meshed with the worm wheel 483. The longer end of the swing arm 46 is installed with an annular rack 485. The fixed shaft 45, the worm wheel 483, the sleeve and the annular rack 485 are fixed. The annular rack 485 is concentrically arranged, and the gear reduction group 484 is arranged between the sliding module 43 and the shaft sleeve, 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 fixed to the shaft sleeve. The large gear is respectively engaged with the small gear and the annular rack 485. When the reduction motor 481 is driven, the annular rack 485 drives the swing arm 46 to swing around the fixed axis 45 after transmission through the worm 482, the worm gear 483 and the gear reduction group 484.

[0032] When the fixed shaft 45 and the ear rod 47 are positioned above and below the steel plate 100, respectively, the reduction motor 481 is activated, driving the worm 482, which in turn causes the worm gear 483 to begin rotating. This worm gear mechanism reduces the rotational speed while increasing the output torque. The rotation of the worm gear 483 is transmitted via the bushing to the pinion, which in turn drives the large gear, further reducing the rotational speed and increasing the torque. The large gear meshes with the annular rack 485, causing it to rotate accordingly. The rotation of the annular rack 485 drives the swing arm 46 around the fixed shaft 45. Because the swing arm 46 is designed with one end longer than the other, and the rear end of the shorter end is fixedly connected to the ear rod 47, the action of the annular rack 485 on the longer end of the swing arm 46 allows the ear rod 47 to rotate axially around the fixed shaft 45 with less effort. This design utilizes the principle of leverage, making the annular rack 485 more efficient in driving the swing arm 46, thereby achieving a more labor-saving operation.

[0033] Example 2: Based on Example 1, Figure 1 、 Figure 2 、 Figure 8 and Figure 9 As shown, it also includes a guide mechanism 5, which includes an auxiliary hydraulic cylinder 51, a linkage bracket 52, a slide frame 53, a slider 54, a positioning bar 55 and a guide column 56. Auxiliary hydraulic cylinders 51 are installed at the lower part of the two uprights 2, and the piston rods of the two auxiliary hydraulic cylinders 51 are connected to the linkage bracket 52. The two ends of the top of the linkage bracket 52 are connected to the slide frame 53. Two sliders 54 are slidably connected in each slide frame 53, and each slider 54 is connected to a guide column 56. An eight-shaped slide groove 21 is provided on the uprights 2 on both sides. The upper end of the eight-shaped slide groove 21 is connected through a straight hole. The guide column 56 slides with the eight-shaped slide groove 21. The slider 54 and the guide column 56 are embedded with a positioning bar 55. The cross section of the positioning bar 55 is L-shaped, and the minimum distance between the two positioning bars 55 is less than the width of the steel plate 100.

[0034] Further, if Figure 8 As shown, a bell-mouth guide plate 57 is also included. The feeding ends on the left sides of the two positioning bars 55 are connected with the bell-mouth guide plates 57, and the distance between the two bell-mouth guide plates 57 gradually converges from left to right.

[0035] Further, if Figure 4 As shown, it also includes a guide rod 12 and a limit block 12. The left side of the right stand 2 is horizontally connected with the guide rod 12. The limit block 13 is slidably connected to the guide rod 12. The limit block 13 is located between the two positioning bars 55 and is provided with a fastening bolt.

[0036] The steel plate 100 is clamped by the 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 to the positioning strip 5 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 and 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 horizontal 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, which 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 inclined guide groove 72 is opened on the linkage connecting block 71. The inclined guide groove 72 is L-shaped, and the angle of the inclined guide groove 72 is 135 degrees. The bottom of the lateral adjustment plate 41 is connected to the transmission connecting rod 73, and the lower end of the transmission connecting rod 73 is connected to the sliding shaft 74. The sliding shaft 74 is located in the inclined guide groove 72. When the linkage bracket 52 moves downward, the sliding shaft 74 is driven to slide backward through the inclined guide groove 72 to move the ear rolling mechanism 4 toward the steel plate 100.

[0038] When the linkage bracket 52 moves downward, the sliding shaft 74 is driven backward through the oblique guide groove 72, and the lateral adjustment plate 41 is moved backward through the transmission link 73. Conversely, when the linkage bracket 52 moves upward, the sliding shaft 74 is driven forward through the oblique guide groove 72, and the lateral adjustment plate 41 is moved forward through the transmission link 73. In this way, the following actions can be achieved: when the positioning bars 55 move downward and away from each other, the fixed shaft 45 and the winding ear rod 47 are inserted into the outside of the steel plate 100; when the positioning bars 55 move upward and toward each other, the fixed shaft 45 and the winding ear rod 47 move away from the steel plate 100. This simplifies the operation steps, makes the actions more consistent, and thus improves work efficiency.

[0039] Example 3: Based on Example 2, Figure 1 and Figure 10 As shown, a cooling mechanism 6 is also included, which 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 on the inside of the base 1, and the high-pressure water pump 62 is installed on the front side of the base 1. A groove 63 is opened in the middle of the upper fixed beam 32 and the lower movable beam 33, and the water outlet pipe 64 is connected to the groove 63. The two water outlet pipes 64 are connected to the opposite sides with nozzles 65 at intervals. The nozzles 65 are evenly distributed between the two adjacent upper forming plates 34 and the 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 a flexible connecting pipe 66. The flexible connecting pipe 66 at the water outlet end of the high-pressure water pump 62 is respectively connected to the two water outlet pipes 64, and the flexible connecting pipe 66 at the water suction end of the high-pressure water pump 62 passes through the base 1 and the circulating water tank 61 in sequence.

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

[0041] After the master hydraulic cylinder 31 drives the upper and lower forming plates 34 and 35 to complete the forming process on the steel plate 100, the high-pressure water pump 62 is activated, drawing water from the circulating water tank 61 via the flexible connecting pipe 66. The water then flows through the outlet pipe 64 and is sprayed onto the surface of the steel plate 100 through the nozzle 65, achieving the cooling and shaping effect. The sprayed water eventually flows back to the circulating water tank 61 for recycling. The water is then removed by the filter 67 to prevent impurities from entering the flexible connecting pipe 66 and the high-pressure water pump 62 through the water intake port and causing blockage, ensuring stable operation of the device.

[0042] Example 4: Based on Example 3, Figure 1 and Figure 2As shown, it also includes a cylinder 8, a connecting member 9, an arc-shaped pusher plate 10 and an inclined guide plate 11. The cylinder 8 is installed on the top of the upper fixed beam 32. The connecting member 9 is connected to the telescopic rod of the cylinder 8. The lower end of the connecting member 9 is connected to the 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 curvature of the arc-shaped pusher plate 10 is consistent with the formed steel plate 100. The upper rear side of the base 1 is connected to the inclined guide plate 11, and 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, the main hydraulic cylinder 31 is activated to shorten, aligning the formed steel plate 100 with the arc-shaped pusher plate 10. Subsequently, the cylinder 8 is activated, which drives the arc-shaped pusher plate 10 backward through the connector 9, pushing the formed steel plate 100 backward, causing it to fall onto the inclined guide plate 11 and then be guided out through the inclined guide plate 11. This method eliminates the need for a robot to remove the steel plate 100, thereby improving removal efficiency.
