Description

Technical Field

[0001] This utility model belongs to the field of metal sheet processing machinery technology, specifically relating to a multi-point adjustable support device for a steel plate bending machine. Background Technology

[0002] Steel plate bending machines are widely used in sheet metal processing. During the bending process, especially when bending long or thick steel plates, the middle of the plate will naturally sag due to the weight of the steel plate and elastic deformation, affecting positioning accuracy and bending accuracy, and ultimately impacting product quality.

[0003] In existing technologies, a simple, integrated support frame is often installed below the lower die of a bending machine. However, the height of this support frame is fixed, making it unable to adapt to different bending angles and varying degrees of sheet deformation. When the bending angle changes, the deformation curve of the steel plate during the bending process also changes. A fixed-height support either fails to provide effective support or interferes with the bending process. Therefore, there is an urgent need for a support device that can flexibly and precisely adapt to different bending conditions. Summary of the Invention

[0004] To overcome the limitations of fixed-height support frames in the prior art, which cannot adapt to different bending angles and varying sheet deformation amounts, and to address the issue that fixed-height supports either fail to provide effective support or interfere with the bending process when the bending angle changes, this invention provides a multi-point adjustable support device for a steel plate bending machine.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A multi-point adjustable support device for a steel plate bending machine mainly includes a frame 1, a support unit 2, a drive mechanism 3, and a control system 4. The frame 1 is installed on the side of the lower die of the bending machine. The support units 2 are evenly installed on the frame 1 through the drive mechanism 3. The drive mechanism 3 is used to drive the support units 2 to move independently up and down in the vertical direction perpendicular to the steel plate feeding direction. The control system 4 is installed on one side of the frame, and the drive mechanism 3 is signal-connected to the control system 4. The control system 4 is used to control the lifting position of each support unit 2.

[0006] Furthermore, the drive mechanism 3 includes a guide groove 31, a lifting frame 32, and a lifting device 33. The guide groove 31 is installed upright on both sides inside the frame 1. Both sides of the lifting frame 32 can be slidably installed in the guide groove 31. The bottom end of the lifting device 33 is installed on the frame 1, and the top end of the lifting device 33 is installed on the lifting frame 32. The support unit 2 is installed on the top of the lifting frame 32. The guide groove 31 guides the lifting frame 32 to prevent the lifting device 33 from being subjected to bending force.

[0007] Furthermore, the lifting device 33 is one of a hydraulic cylinder, a pneumatic cylinder, or an electric push rod.

[0008] Furthermore, the support unit 2 is a support roller or support wheel. The support roller or support wheel is rotatably mounted on top of the drive mechanism 3.

[0009] Furthermore, the control system 4 includes a human-machine interface 41 and a controller 42. The human-machine interface 41 is connected to the controller 42 by signal, and the controller 42 is connected to the drive mechanism 3 by signal. The bending angle of the target workpiece and / or the target height value of each support unit (2) can be input through the human-machine interface 41.

[0010] The beneficial effects of this utility model are: This invention utilizes multiple independently and precisely controllable support units to perfectly match the elastic deformation curve of the steel plate during bending, providing uniform and accurate support and completely solving the problem of inconsistent bending angles caused by sagging due to its own weight. Through the control system, the height of each support point can be quickly adjusted, easily adapting to the processing of steel plates of different thicknesses, materials, and bending angles, demonstrating strong versatility. Operation is simple; by inputting key parameters, the system can automatically adjust all support points, greatly improving production efficiency and reducing reliance on operator experience.

[0017] This utility model discloses a multi-point adjustable support device for a steel plate bending machine. The multi-point adjustable support device mainly includes a frame 1, support units 2, a drive mechanism 3, and a control system 4. The frame 1 is installed on the lower die side of the bending machine. The support units 2 are evenly installed on the frame 1 via the drive mechanism 3, which drives the support units 2 to independently move up and down in a vertical direction perpendicular to the steel plate feeding direction. The control system 4 is installed on one side of the frame, and the drive mechanism 3 is signal-connected to the control system 4. The control system 4 controls the lifting position of each support unit 2. During operation, the support unit 2 is raised and lowered via the drive mechanism 3. Multiple independently and precisely controllable support units perfectly match the elastic deformation curve of the steel plate during bending, providing uniform and accurate support and completely solving the problem of inconsistent bending angles caused by sag due to its own weight.

[0019] The lifting device 33 is one of a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, and has a simple structure, stable operation, and reliable performance.

[0020] The support unit 2 is a support roller or support wheel. The support roller or support wheel is rotatably mounted on the top of the drive mechanism 3 and can rotate freely with the feeding of the steel plate, reducing the friction on the steel plate.

Multiple support units that can be independently and precisely controlled can perfectly match the elastic deformation curve of the steel plate during the bending process, providing uniform and accurate support for the steel plate and completely solving the problem of inconsistent bending angles caused by self-weight sag; through the control system, the height of each support point can be quickly adjusted, easily adapting to the processing of steel plates of different thicknesses, materials and bending angles, with extremely strong versatility; the operation is simple, and the system can automatically complete the adjustment of all support points by inputting key parameters, which greatly improves production efficiency and reduces the dependence on the operator's experience.
