Embodiment 1

[0035] like figure 1As shown, this embodiment provides a bending plate follower supporting device, which is mainly used in bending equipment such as bending machines, and supports during the bending process of the plate, so as to ensure the bending accuracy of the plate and the stability of the plate. The surface quality of the material is especially important for large-sized and thin sheets. The main body of the device is mainly composed of a base 100 , an active support rod 200 , a driven support rod 300 , a support plate 400 and a drive cylinder 500 , forming a connecting rod overturning support structure.

[0036] Specifically, the base 100 is used as the installation foundation of the whole device, which can be directly used as the foundation on the ground, or fixedly installed on the ground, and a pit is opened on the ground below the base 100, the cylinder of the driving cylinder 500 is hinged on the base 100, and the cylinder The lower part of the cylinder extends int...

Embodiment 2

[0050] The foregoing embodiment provides a mechanical structure that can realize the sheet metal bending follower device, but to complete the reliable follow-up action of the mechanical part, as well as other flipping actions, it is necessary to rely on precise control. On the basis of the mechanical structure of the follow-up material holding device, the plate follow-up material holding hydraulic system 600 is provided to control the expansion and contraction of the driving cylinder 500 to complete the turning action requirement. At the same time, it also solves the problems of extremely high requirements and poor reliability of the follow-up tracking support control system of the existing bending machine.

[0051] like Image 6 As shown, the hydraulic system 600 of the curved plate follower supporting material is composed of three parts: an oil tank 610 , a material supporting control part and an oil supply part 620 . The oil inlet side of the oil supply part 620 is connect...
