However, this method requires the staff to clamp and position each part and component in advance before the bending process. When the number of plates to be processed is large, the workload of the staff for clamping the parts and components will increase accordingly, which will affect the bending processing efficiency of the parts and components.

[0017] In this embodiment: the base 1 is used to provide a mounting surface for each component of the device, the support plate 11 is located directly above the base 1, and a plurality of support rods 12 are fixedly connected between the base 1 and the support plate 11 to provide support for the support plate 11 and the mounting plate 3 that slides vertically below the support plate 11. The workbench 2 is used to support the component plate to be processed. A mounting groove for the bending mold 21 is provided in the middle of the workbench 2. The bending mold 21 is detachably connected to the inner side of the mounting groove in the middle of the workbench 2, which can be easily replaced by the staff according to the required processing component model. , several guide seats 22 are respectively fixed on both sides of the workbench 2, and the guide seats 22 are used to guide the limit plates 23 that slide horizontally at their tops, so that during the bending operation, the limit plates 23 can slide smoothly in the direction of the component plate. The lower inclined block 24 is fixed on one side of the limit plate 23, and the lower inclined block 24 is used to drive the limit plate 23 to slide horizontally. The mounting plate 3 slides vertically above the workbench 2, and the mounting plate 3 is used to provide a mounting surface for the bending tool 31 and the upper inclined block 32, and can drive the bending tool 31 and the upper inclined block 32 to move vertically. The bending tool 31 corresponds to the position of the bending die 21. When in use, the staff places the component plate to be processed on the top of the workbench 2, and then controls the mounting plate 3 to move vertically downward, driving the bending tool 31 to bend the component plate. In the process of the mounting plate 3 being driven downward, the bending tool 31 will also drive the several upper inclined blocks 32 on the top of the mounting plate 3 to move downward synchronously. The several upper inclined blocks 32 will first squeeze the several lower inclined blocks 24 below. Under the action of the inclined surface, the several lower inclined blocks 24 will be subjected to the lateral force and will move together in the direction of the component plate. When the lower inclined block 24 slides horizontally to the end point, the bending tool 31 will move to contact with the top of the component plate to perform the bending operation. At this time, several lower inclined blocks 24 can limit the two ends of the component plate at the same time to prevent the two ends of the component from curling up during the bending process. After the bending tool 31 squeezes the bent part of the plate into the inner side of the bending mold 21 to complete the bending operation, the mounting plate 3 is controlled to rise upward, and several lower inclined blocks 24 will slide outward to reset, which can facilitate the staff to take out the component plate that has been bent and perform the bending operation on the next component plate.
[0018] A guide groove 221 is provided inside the guide seat 22, a guide rod 222 is fixedly connected to the inner side of the guide groove 221, a driving block 223 is slidably connected to the outer side of the guide groove 221, a limit plate 23 is fixedly connected to the top of the driving block 223, a spring is provided between one side of the driving block 223 and the guide groove 221; the guide groove 221 provides a mounting surface for the guide rod 222, a clearance groove having a size matching that of the guide rod 222 is provided inside the driving block 223, and the guide rod 222 is used to guide the horizontal sliding of the driving block 223, so that a plurality of limit plates 23 can be moved when performing a bending operation. The plate 23 can slide smoothly in the direction of the component plate, and when the limit plate 23 slides horizontally under the action of the lower inclined block 24, the driving block 223 follows the limit plate 23 to slide synchronously on the inside of the guide groove 221, which will squeeze the spring inside the guide groove 221. When the staff completes the bending operation and controls the mounting plate 3 to rise upward, several lower inclined blocks 24 will slide outward and reset under the action of the elastic release force of the spring inside the guide groove 221, which is convenient for the staff to take out the component plate that has been bent and perform the bending operation on the next component plate.
[0019] A hydraulic telescopic rod 111 is fixedly connected to the bottom end of the support plate 11, and one end of the hydraulic telescopic rod 111 is fixedly connected to the mounting plate 3; the hydraulic telescopic rod 111 between the support plate 11 and the mounting plate 3 is mainly used to provide a stable downward pressure, so that the bending tool 31 can slide downward under the drive of the hydraulic telescopic rod 111, and exert sufficient pressure on the required component plate to bend or shape it, thereby completing the bending process of the component plate.
[0020] The inner side of the limit plate 23 is rotatably connected to a plurality of rotating cylinders 231; a damping layer is arranged on the outer side of the rotating cylinder 231. When the limit plate 23 moves toward the direction of the component plate under the action of the lower inclined block 24, the plurality of rotating cylinders 231 will rotate along the top end of the plate. The arrangement of the rotating cylinders 231 can reduce the friction between the limit plate 23 and the surface of the plate, so that the limit plate 23 can slide more smoothly toward the direction of the plate, thereby completing the limitation of both ends of the plate.
[0021] A positioning rod 211 is provided at the top of the workbench 2; the positioning rod 211 provided at the top of the workbench 2 is used to position the component plate. After the staff places the component plate on the top of the workbench 2, one end of the plate is aligned with the two positioning rods 211 at the top of the workbench 2. At this time, the bending tool 31 will be exactly aligned with the bending part in the middle of the plate. The staff can drive the mounting plate 3 to move downward through the hydraulic telescopic rod 111 to perform the bending operation on the plate.
[0022] The working principle and use process of the utility model are as follows: when in use, the staff places the component plate to be processed on the top of the workbench 2, and aligns the component plate with the two positioning rods 211 at the top of the workbench 2, and then the hydraulic telescopic rod 111 can be controlled to drive the mounting plate 3 to move vertically downward, and drive the bending tool 31 to bend the component plate. In the process of driving the bending tool 31 to move downward, the mounting plate 3 will also drive the several upper inclined blocks 32 at the top of the mounting plate 3 to move downward synchronously. The several upper inclined blocks 32 will first squeeze the several lower inclined blocks 24 below. Under the action of the inclined surface, the several lower inclined blocks 24 will be subjected to the lateral force and will move together in the direction of the component plate. When the lower inclined block 24 slides horizontally to the end point, the bending tool 31 will just move to contact with the top of the component plate for bending operation. At this time, the several lower inclined blocks 24 can move simultaneously When the bending tool 31 squeezes the bending part of the plate into the inner side of the bending mold 21 to complete the bending operation, the mounting plate 3 is controlled to rise upward, and the lower inclined blocks 24 slide outward and reset under the action of the spring inside the guide groove 221, so that the staff can take out the bent plate and perform the bending operation on the next plate. Through the cooperation of the lower inclined block 24 and the upper inclined block 32, when the staff is bending the plate, the limiting plates 23 can slide in the direction of the plate, and at the same time, the two ends of the plate are limited to prevent the two ends of the plate from curling up during the bending process, eliminating the need for the staff to clamp the two ends of the component in advance, reducing the workload of the staff, and thus improving the bending efficiency of the plate.
