Description

Technical Field

[0001] This utility model relates to the technical field of bending equipment, and specifically to a bending mechanism. Background Technology

[0002] Traditional bending mechanisms include a motor, a ball screw, and a bending head. The parts that need to be bent are placed in the processing position, the motor drives the ball screw to rotate, and the ball screw drives the bending head to abut against the parts to achieve the bending operation.

[0003] To maximize efficiency, existing bending mechanisms are typically equipped with tonnage requirements. Small-tonnage bending mechanisms can only bend small-tonnage parts, while large-tonnage bending mechanisms can only bend large-tonnage parts. Large-tonnage bending mechanisms generally involve directly increasing the capacity of the servo motor, thereby outputting greater power and enabling high-tonnage pressing and bending.

[0004] However, companies with limited funds cannot simultaneously equip themselves with bending equipment of various tonnages, and it is also difficult to standardize parts, requiring processing of both large and small tonnage components. Equipping themselves directly with large-tonnage bending equipment would be particularly wasteful for processing small-tonnage parts, increasing operating costs. Utility Model Content

[0005] The purpose of this invention is to provide a bending mechanism that solves the problems mentioned in the background art by improving the driving structure.

[0006] To achieve the above objectives, the present invention provides a bending mechanism, including a worktable, a bending power component, and an auxiliary power component. The worktable has a part processing position. The bending power component includes a main motor, a reducer, a ball screw, and a pressure joint. A mounting frame is provided on the worktable, and the main motor is fixed to the mounting frame. The output end of the main motor is connected to the reducer, and the output end of the reducer is connected to the ball screw. The ball screw is rotatably connected to the pressure joint, which is confined and can move closer to or further away from the part processing position. The auxiliary power component is located on one side of the bending power component and includes an auxiliary motor and a connecting belt. The auxiliary motor is fixed to the mounting frame, and the connecting belt connects the auxiliary motor and the ball screw.

[0007] Furthermore, the ball screw includes a connecting seat and a rod body. One end of the connecting seat is connected to the rod body, and the other end is connected to the output end of the reducer. A synchronous pulley is provided on the connecting seat, and a connecting pulley is provided at the output end of the auxiliary motor. The connecting belt connects the connecting pulley and the synchronous pulley.

[0008] Furthermore, the bending mechanism also includes a switching clutch, which is disposed on the connecting seat and drives the connecting seat to connect or disconnect from the output end of the reducer.

[0009] Furthermore, the mounting frame includes a first support frame and a second support frame, the main motor is fixed on the first support frame, the auxiliary motor is fixed on the second support frame, and the second bracket is located on one side of the first bracket.

[0010] Furthermore, the workbench includes a fixed plate and a supporting side plate, the pressure joint is slidably connected to the supporting side plate, and the part processing position is provided between the fixed plate and the supporting side plate.

[0011] Furthermore, there are two supporting side plates arranged opposite to each other, and the fixing plate connects the two supporting side plates. The supporting side plates are provided with grooves, and the fixing plate is located below the grooves, forming the part processing position at the grooves.

[0012] Furthermore, a reinforcing beam connects the two supporting side plates.

[0013] Furthermore, the bending power component and the auxiliary power component are in two sets, each set being located close to one side of the worktable. The two sets of bending power components work synchronously, and the two sets of auxiliary power components work synchronously.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The reducer amplifies the torque of the main motor, and the ball screw converts the rotary motion into the linear motion of the crimping joint. When heavy-duty bending operations are required, the main motor and auxiliary motor work simultaneously, and their torques are simultaneously output to the ball screw, increasing the crimping force of the crimping joint and enabling heavy-duty bending operations. When light-duty bending operations are required, the main motor works alone, and the auxiliary motor does not work. In this case, the ball screw torque is smaller, and the crimping force of the crimping joint is smaller, enabling light-duty bending operations. By adding an auxiliary power component, this application can meet the bending processing requirements of different tonnages. The processing tonnage can be selected according to the actual processing requirements, which greatly reduces the motor capacity while meeting the bending requirements, achieving a simultaneous reduction in overall machine cost and power consumption, and making it more widely applicable.

[0016] 2. The bending mechanism also includes a switching clutch. When the switching clutch drive connector is connected to the output end of the reducer, bending operations can be performed with both the main motor and the auxiliary motor operating simultaneously, or with the main motor operating alone and the auxiliary motor not operating. When the switching clutch drive connector is disconnected from the output end of the reducer, bending operations can be performed with only the auxiliary motor operating. By setting the switching clutch, bending operations under three different tonnage modes can be achieved.

[0017] 3. The bending power component and auxiliary power component are in two sets, each set is located near one side of the worktable. The two sets of bending power components work synchronously, and the two sets of auxiliary power components work synchronously. This ensures that the pressure on the crimp joint is even, avoiding excessive local extrusion pressure that could lead to uneven bending. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] Reference Figures 1 to 3 As an embodiment of this utility model, a bending mechanism includes a worktable 1, a bending power component 2, and an auxiliary power component 3. The worktable 1 has a part processing position 11. The bending power component 2 includes a main motor 21, a reducer 22, a ball screw 23, and a pressure joint 24. The worktable 1 has a mounting frame 12. The main motor 21 is fixed on the mounting frame 12. The output end of the main motor 21 is connected to the reducer 22, and the output end of the reducer 22 is connected to the ball screw 23. The ball screw 23 is rotatably connected to the pressure joint 24. The pressure joint 24 is defined and can move closer to or away from the part processing position 11. The auxiliary power component 3 is located on one side of the bending power component 2. The auxiliary power component 3 includes an auxiliary motor 31 and a connecting belt 32. The auxiliary motor 31 is fixed on the mounting frame 12, and the connecting belt 32 connects the auxiliary motor 31 and the ball screw 23.

[0029] The reducer 22 amplifies the torque of the main motor 21, and the ball screw 23 converts the rotary motion into the linear motion of the crimping head 24. When heavy-duty bending operations are required, the main motor 21 and the auxiliary motor 31 work simultaneously, and their torques are simultaneously output to the ball screw 23, increasing the crimping force of the crimping head 24 and enabling heavy-duty bending operations. When light-duty bending operations are required, the main motor 21 works alone, and the auxiliary motor 31 does not work. At this time, the torque of the ball screw 23 is smaller, and the crimping force of the crimping head 24 is smaller, enabling light-duty bending operations. In this application, by adding the auxiliary power component 3, bending processing requirements of different tonnages can be met. The processing tonnage can be selected according to the actual processing requirements, which greatly reduces the motor capacity while meeting the bending requirements, achieving a simultaneous reduction in overall machine cost and power consumption, and making it more widely applicable.

[0030] Specifically, the ball screw 23 includes a connecting seat 231 and a rod body 232. One end of the connecting seat 231 is connected to the rod body 232, and the other end is connected to the output end of the reducer 22. A synchronous pulley 25 is provided on the connecting seat 231, and a connecting pulley 26 is provided at the output end of the auxiliary motor 31. A connecting belt 32 connects the connecting pulley 26 and the synchronous pulley 25. After the auxiliary motor 31 rotates, it can transmit torque to the connecting seat 231 through the connecting belt 32. At the same time, the torque of the main motor 21 is amplified by the reducer 22 and transmitted to the connecting seat 231, and then synchronously transmitted to the rod body 232. The worktable 1 includes a fixed plate 13 and a supporting side plate 14. A pressure joint 24 is slidably connected to the supporting side plate 14. A connecting sleeve is provided on the supporting side plate 14. The connecting sleeve has an internal thread and is threadedly connected to the rod body 232. After the rod 232 rotates, it can drive the connecting sleeve to move downward, thereby converting the rotational motion into the linear motion of the connecting sleeve. After the connecting sleeve moves downward, it can drive the crimping head 24 to move downward synchronously, realizing the crimping and bending operation.

[0031] The mounting frame 12 includes a first support frame 121 and a second support frame 122. The main motor 21 is fixed on the first support frame 121, and the auxiliary motor 31 is fixed on the second support frame 122. The second support frame 122 is located on one side of the first support frame 121 and the distance between them is small, which facilitates the adjacent arrangement of the auxiliary motor 31 and the main motor 21, and facilitates the connection of the belt 32 to the auxiliary motor 31 and the ball screw 23.

[0032] A part processing position 11 is provided between the fixed plate 13 and the supporting side plate 14. In this embodiment, there are two supporting side plates 14 arranged opposite to each other, and the fixed plate 13 connects the two supporting side plates 14. The supporting side plates 14 are provided with grooves 141, and the fixed plate 13 is located below the grooves 141. The part processing position 11 is formed at the grooves 141, and the crimping joint 24 can move toward the grooves 141. In order to further enhance the connection stability between the fixed plate 13 and the supporting side plates 14, a reinforcing beam 15 is connected between the two supporting side plates 14. One or more reinforcing beams 15 can be provided according to the actual use.

[0033] Furthermore, the bending mechanism also includes a switching clutch 4, which is mounted on the connecting seat 231. The switching clutch 4 drives the connecting seat 231 to connect or disconnect from the output end of the reducer 22.

[0034] Specifically, the switching clutch 4 is located within the connecting seat 231, directly driving the connecting seat 231 to connect or disconnect from the output end of the reducer 22. When the switching clutch 4 drives the connecting seat 231 to connect with the output end of the reducer 22, bending operations can be performed simultaneously by the main motor 21 and the auxiliary motor 31. Alternatively, the auxiliary motor 31 can be disabled, with the main motor 21 operating alone for bending operations. In this case, to avoid excessive power consumption of the main motor 21, the pulley needs to be removed to prevent the auxiliary motor 31 from interfering with the work of the main motor 21. When the switching clutch 4 drives the connecting seat 231 to disconnect from the output end of the reducer 22, bending operations can be performed with the auxiliary motor 31 operating alone. In this embodiment, by setting the switching clutch 4, bending operations under three tonnage modes can be achieved, broadening the applicability. The processing tonnage can be selected according to actual processing needs, significantly reducing motor capacity while meeting bending requirements, thus simultaneously reducing overall machine cost and power consumption.

[0035] Furthermore, the bending power component 2 and the auxiliary power component 3 are in two sets, each set being located near one side of the worktable 1. The two sets of bending power components 2 work synchronously, and the two sets of auxiliary power components 3 work synchronously. This ensures that the pressure on the pressure joint 24 is balanced, avoiding excessive local extrusion pressure that could lead to uneven bending.

[0036] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
