This utility model relates to the field of boiler inner lining plate production, and discloses a high-precision multi-directional bending device for boiler inner lining plates. It includes a
processing table, with a bending mechanism mounted on the upper part of the
processing table. The bending mechanism includes an auxiliary component and a bending component. The bending component is located in front of the auxiliary component and includes a housing. The housing is fixedly connected to the
processing table. Bending components are provided at both the upper and lower parts of the housing. Each bending component includes a guide rail, which is fixedly connected to the housing. A guide block is slidably connected to the outside of the guide rail. A
hydraulic cylinder is fixedly connected to the side of each guide block that is close to each other. In this utility model, by setting the cooperation between the bending mechanism and the auxiliary component, the device can limit the plate material through the auxiliary component to cooperate with the bending operation of the bending component, eliminating the need for manual operation. Furthermore, by setting two sets of bending components, multi-directional bending of the inner lining plate can be achieved, making it more practical.
