Description

Technical Field

[0001] This invention relates to the field of hydraulic bending machine technology, specifically to a torsion shaft synchronous hydraulic bending machine unit. Background Technology

[0002] With the continuous development of modern industrial manufacturing technology, bending of metal sheets has become one of the key processes in many industries. In order to meet the bending needs of workpieces of different shapes and sizes, a torsion shaft synchronous hydraulic bending machine unit has been widely used due to its high efficiency and precision.

[0003] While existing torsion shaft synchronous hydraulic bending machines play a vital role in industrial production, several technical shortcomings remain. For example, current equipment often lacks the flexibility to switch the number of bends per workpiece, limiting its adaptability to different bending requirements. Furthermore, workpieces may shift during bending due to unstable positioning, affecting bending quality and accuracy. Simultaneously, during continuous production, waste chips easily accumulate on the bearing surface, and existing equipment typically lacks effective automatic cleaning mechanisms. This increases manual maintenance workload and can negatively impact equipment performance and workpiece quality. These technical deficiencies urgently need to be addressed through technological innovation to meet the growing demand for efficient and precise bending processes. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a torsion shaft synchronous hydraulic bending machine unit, comprising a base, a support is provided on the upper part of the base, a hydraulic cylinder is installed on the top of the support, the output shaft of the hydraulic cylinder is connected to a bending mechanism, and a support platform is also provided on the upper part of the base below the bending mechanism, with a cleaning component provided on the support platform.

[0006] The bending mechanism includes a hollow shaft connected to the output shaft of a hydraulic cylinder. A base plate is connected to the lower end of the hollow shaft. A bending plate one is vertically integrally formed on one side of the base plate, and a bending plate two is hinged to the other side of the base plate. A switching drive assembly for driving the bending plate two to rotate is provided on the base plate, thereby completing the process of switching the number of bends. Two positioning components for positioning the workpiece are provided at the bottom of the base plate.

[0007] Preferably, the position of the support platform corresponds to the position of the base plate, and the width of the support platform is equal to the width of the base plate. When both the first folding plate and the second folding plate are in a vertical state, the first folding plate and the second folding plate correspond exactly to the two sides of the support platform.

[0008] Preferably, the switching drive assembly includes a movable plate that is longitudinally slidably sleeved outside the hollow shaft. A connecting rod is integrally formed at one end of the movable plate away from the hollow shaft. Both ends of the connecting rod are vertically provided with racks. The switching drive assembly also includes two arc-shaped gears disposed on the side of the folding plate away from the substrate. The two arc-shaped gears mesh with the two racks respectively. The switching drive assembly also includes a drive unit for driving the longitudinal displacement of the movable plate.

[0009] Preferably, the drive unit includes a servo motor installed on the top side inside the hollow shaft. The output shaft of the servo motor is connected to a screw. A connecting block is screwed to the outside of the screw. The two ends of the connecting block are fixedly disposed on the inside sides of one end of the moving plate. Guide grooves are provided on both sides of the hollow shaft, and the two ends of the connecting block pass through the guide grooves.

[0010] Preferably, the hinge point of the arc gear and the second folding plate is located on the same axis, and the upper part of the base plate is provided with two through holes, so that the lower end of the rack and the other end of the arc gear can pass through the through holes.

[0011] Preferably, the positioning element includes a positioning rod that slides longitudinally through the bottom of the substrate, the lower end of the positioning rod is connected to a positioning plate, and the upper end of the positioning rod is connected to a flange. A spring is sleeved on the outside of the positioning rod, and the two ends of the spring are respectively connected to the upper part of the positioning plate and the bottom of the substrate.

[0012] Preferably, when the spring is in the reset state, the bottom of the positioning plate is lower than the bottom of the first folding plate.

[0013] Preferably, the cleaning component includes a limiting seat disposed on one edge of the support platform, a stepper motor is mounted on one side of the limiting seat, the output shaft of the stepper motor is connected to a threaded rod, a nut sleeve is screwed onto the outside of the threaded rod, an L-shaped rod is disposed on the upper side of the nut sleeve, and a scraper is connected to the other end of the L-shaped rod, the scraper being attached to the upper part of the support platform.

[0014] Preferably, a collection box is magnetically attached to one side of the support platform, and an inclined surface corresponding to the collection box is provided on the upper part of the support platform.

[0015] This invention provides a torsion shaft synchronous hydraulic bending machine unit, which has the following advantages compared with the prior art:

[0016] 1. This torsion shaft synchronous hydraulic bending machine unit can easily achieve one or two bends on a workpiece by controlling different rotation angles of the second bending plate. When the second bending plate rotates to a vertical position, in conjunction with the hydraulic cylinder, the first and second bending plates can perform precise double-bend bending operations on the workpiece; while when the second bending plate remains horizontal, single-bend bending can be performed. This design not only improves the applicability and flexibility of the equipment, but also simplifies the operation process, increases production efficiency, and provides a more precise and efficient solution for workpieces with different bending requirements.

[0017] 2. This torsion shaft synchronous hydraulic bending machine unit employs a spring-loaded positioning plate to fix the workpiece in place, ensuring that the workpiece does not shift during the bending process. As the base plate moves downward, the positioning plate contacts and gradually presses against the workpiece, relying on the elasticity of the spring to gradually apply pressure to the workpiece, thereby ensuring the stability and positioning accuracy of the workpiece during bending. This design effectively improves bending quality and reduces errors caused by workpiece shift.

[0018] 3. This type of torsion shaft synchronous hydraulic bending machine unit, driven by a stepper motor, can automatically remove waste from the bearing platform, ensuring the cleanliness and flatness of the workpiece placement surface. This design reduces the need for manual cleaning and improves the automation level of the production process. The waste is pushed by the scraper and slides down the slope into the collection box, which not only keeps the working environment clean, but also helps to improve the stability of the workpiece during bending and the quality of the finished product.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-4 This invention provides three technical solutions:

[0026] Example 1

[0027] Please see Figure 1 In this embodiment of the invention, a torsion shaft synchronous hydraulic bending machine unit includes a base 1, a support 2 is provided on the upper part of the base 1, a hydraulic cylinder 3 is installed on the top of the support 2, the output shaft of the hydraulic cylinder 3 is connected to a bending mechanism 4, and a support platform 5 is also provided on the upper part of the base 1 below the bending mechanism 4, and a cleaning component 6 is provided on the support platform 5.

[0028] Please see Figure 2 In this embodiment of the invention, the bending mechanism 4 includes a hollow shaft 41 connected to the output shaft of the hydraulic cylinder 3. The lower end of the hollow shaft 41 is connected to a base plate 42. A bending plate 43 is vertically integrally formed on one side of the base plate 42, and a bending plate 44 is hinged on the other side of the base plate 42. A switching drive assembly 45 for driving the bending plate 44 to rotate is provided on the base plate 42, thereby completing the process of switching the number of bends. Two positioning members 46 for positioning the workpiece are provided at the bottom of the base plate 42.

[0029] Please see Figures 2-3In this embodiment of the invention, the switching drive assembly 45 includes a movable plate 451 that is longitudinally slidably sleeved outside the hollow shaft 41. A connecting rod 452 is integrally formed at one end of the movable plate 451 away from the hollow shaft 41. Both ends of the connecting rod 452 are vertically provided with racks 453. The switching drive assembly 45 also includes two arc-shaped gears 454 disposed on the side of the second folding plate 44 away from the base plate 42. The two arc-shaped gears 454 mesh with the two racks 453 respectively. The switching drive assembly 45 also includes a drive part for driving the longitudinal displacement of the movable plate 451.

[0030] Please see Figures 2-3 In this embodiment of the invention, the drive unit includes a servo motor 456 installed on the top side inside the hollow shaft 41. The output shaft of the servo motor 456 is connected to a screw 457. A connecting block 455 is screwed onto the outside of the screw 457. The two ends of the connecting block 455 are fixedly disposed on the two sides inside one end of the moving plate 451. Guide grooves 458 are provided on both sides of the hollow shaft 41. The two ends of the connecting block 455 pass through the guide grooves 458.

[0031] In this embodiment, during use, the servo motor 456 drives the screw 457 to rotate. The screw 457 causes the moving plate 451 to move longitudinally on the hollow shaft 41, which in turn drives the connecting rod 452 to move longitudinally. When the connecting rod 452 moves downward, the racks 453 at both ends of the connecting rod 452 drive the arc gear 454 to rotate counterclockwise, and vice versa. When the arc gear 454 rotates counterclockwise, it drives the folding plate 44 to rotate upward. When the arc gear 454 rotates clockwise, it drives the folding plate 44 to rotate upward. The second 44 is rotated downwards to a vertical position, and then the workpiece is placed on the support 5. If the workpiece is to be bent twice, the second 44 is rotated to a vertical position, and then the hydraulic cylinder 3 drives the base plate 42 at the lower end of the hollow shaft 41 to move downwards. The first 43 and the second 44 will then bend the workpiece. If the workpiece is to be bent once, the second 44 is rotated to a horizontal position, and then the hydraulic cylinder 3 drives the base plate 42 at the lower end of the hollow shaft 41 to move downwards. In this way, the first 43, which is integrally formed with the base plate 42, will press down on the workpiece, causing the workpiece to be bent into a bend.

[0032] For further details, please refer to Figures 2-3 In this embodiment of the invention, the position of the support platform 5 corresponds to the position of the base plate 42, and the width of the support platform 5 is equal to the width of the base plate 42. When both the first folding plate 43 and the second folding plate 44 are in a vertical state, the first folding plate 43 and the second folding plate 44 correspond exactly to the two sides of the support platform 5. When the first folding plate 43 and the second folding plate 44 move down, they can bend the workpiece and complete the bending operation.

[0033] For further details, please refer to Figures 2-3In this embodiment of the invention, the hinge point of the arc gear 454 and the second folding plate 44 is located on the same axis. The upper part of the base plate 42 is provided with two through holes, so that the lower end of the rack 453 and the other end of the arc gear 454 can pass through the through holes. When the rack 453 drives the arc gear 454 to rotate, the two can move in the through holes.

[0034] Example 2 differs from Example 1 in that:

[0035] Please see Figure 2 In this embodiment of the invention, the positioning member 46 includes a positioning rod 461 that slides longitudinally through the bottom of the substrate 42. The lower end of the positioning rod 461 is connected to the positioning plate 462, and the upper end of the positioning rod 461 is connected to the flange 464. A spring 463 is sleeved on the outside of the positioning rod 461, and the two ends of the spring 463 are respectively connected to the upper part of the positioning plate 462 and the bottom of the substrate 42.

[0036] In this embodiment, when the substrate 42 moves down, the positioning plate 462 will contact the workpiece. As the substrate 42 continues to move down, the positioning plate 462 will gradually press the workpiece with the elasticity of the spring 463 to prevent the workpiece from shifting when bending.

[0037] Please see Figure 2 In this embodiment of the invention, when the spring 463 is in the reset state, the bottom of the positioning plate 462 is lower than the bottom of the bending plate 43. When the bending plate 43 moves down, the positioning plate 462 will first contact the workpiece to complete the positioning operation, and then perform the bending operation to prevent the workpiece from shifting.

[0038] Example 3 differs from Example 1 in that:

[0039] Please see Figure 1 and Figure 4 In this embodiment of the invention, the cleaning component 6 includes a limiting seat 61 disposed on one side edge of the support 5. A stepper motor 62 is installed on one side of the limiting seat 61. The output shaft of the stepper motor 62 is connected to a threaded rod 63. A nut sleeve 64 is screwed onto the outside of the threaded rod 63. An L-shaped rod 65 is disposed on the upper side of the nut sleeve 64. A scraper 66 is connected to the other end of the L-shaped rod 65. The scraper 66 is attached to the upper part of the support 5.

[0040] Please see Figure 1 and Figure 4 In this embodiment of the invention, a collection box 51 is magnetically attached to one side of the support platform 5, and an inclined surface 52 corresponding to the collection box 51 is provided on the upper part of the support platform 5.

[0041] In this embodiment, when there is a lot of waste on the bearing platform 5, the stepper motor 62 is started to drive the threaded rod 63 to rotate. The threaded rod 63 drives the nut sleeve 64 to move, and the nut sleeve 64 will cause the scraper 66 at the other end of the L-shaped rod 65 to move laterally. The scraper 66 will scrape the waste on the bearing platform 5. When the waste is scraped to the inclined surface 52 on the bearing platform 5, the waste will slide off the inclined surface 52 into the collection box 51, completing the cleaning operation of the bearing platform 5. This allows the workpiece to be placed flat on the bearing platform 5, which is convenient for bending the workpiece.

[0042] Working principle: The servo motor 456 drives the screw 457 to rotate, which in turn causes the moving plate 451 to move longitudinally on the hollow shaft 41. This, in turn, causes the connecting rod 452 to move longitudinally. When the connecting rod 452 moves downward, the racks 453 at both ends of the connecting rod 452 drive the arc gear 454 to rotate counterclockwise, and vice versa. When the arc gear 454 rotates counterclockwise, it drives the second folding plate 44 to rotate upward. When the arc gear 454 rotates clockwise, it drives the second folding plate 44 to rotate upward. Rotate downwards to a vertical position, then place the workpiece on the support 5. If the workpiece is to be bent twice, rotate the second folding plate 44 to a vertical position, and then the hydraulic cylinder 3 drives the base plate 42 at the lower end of the hollow shaft 41 to move downwards. The first folding plate 43 and the second folding plate 44 will then bend the workpiece. If the workpiece is to be bent once, rotate the second folding plate 44 to a horizontal position, and then the hydraulic cylinder 3 drives the base plate 42 at the lower end of the hollow shaft 41 to move downwards. In this way, the first folding plate 43, which is integrally formed with the base plate 42, will press down on the workpiece, causing the workpiece to be bent into a bend.

[0043] When the substrate 42 moves down, the positioning plate 462 will contact the workpiece. As the substrate 42 continues to move down, the positioning plate 462 will gradually press the workpiece with the elasticity of the spring 463 to prevent the workpiece from shifting when bending.

[0044] When there is a lot of waste on the bearing platform 5, the stepper motor 62 is started to drive the threaded rod 63 to rotate. The threaded rod 63 drives the nut sleeve 64 to move, and the nut sleeve 64 will cause the scraper 66 at the other end of the L-shaped rod 65 to move laterally. The scraper 66 will scrape the waste on the bearing platform 5. When the waste is scraped to the inclined surface 52 on the bearing platform 5, the waste will slide off the inclined surface 52 into the collection box 51, completing the cleaning operation of the bearing platform 5. This allows the workpiece to be placed flat on the bearing platform 5, which is convenient for bending the workpiece.

[0045] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
