Supporting and positioning device used for curved plate manufacturing

Abstract

The invention belongs to the related technical field of ship complex curvature plate machining, and discloses a supporting and positioning device used for curved plate manufacturing. The positioning device comprises a transverse guide rail, a longitudinal guide rail and supporting units, the transverse guide rail and the longitudinal guide rail are used for correspondingly adjusting the transverseposition and the longitudinal position of the supporting units so as to adapt to the size of a to-be-supported curved plate; a plurality of supporting units are arranged, the supporting units are used for making contact with the to-be-supported curved plate so that supporting the curved plate can be carried out; the supporting units comprise bases, hydraulic cylinders and magnetic sucking discs,the bases are used for connecting the supporting units with the longitudinal guide rail, the hydraulic cylinders are connected with the magnetic sucking discs, the up and down positions of the magnetic sucking discs are adjusted through up-and-down motion of pistons in the hydraulic cylinders, and the magnetic sucking discs are attracted to the surface of the to-be-supported curved plate. By meansof the supporting and positioning device used for curved plate manufacturing, effective positioning of the plate is achieved, the curved plate is sufficiently restrained in the manufacturing process,and the problems that a clamp is long in mounting and dismounting time and position interference occurs are solved.

Description

technical field [0001] The invention belongs to the technical field related to the processing of complex curvature plates of ships, and more specifically relates to a support and positioning device for the manufacture of curved plates. Background technique [0002] Incremental forming is a commonly used technical method in the processing of complex curvature plates for ships. Incremental forming usually uses rollers as processing tools to achieve local deformation of the sheet by constructing local bending conditions of the sheet or reducing the local thickness of the sheet, and the rotation of the processing tool drives the sheet to move, so that the deformation gradually expands to the whole. During its processing, a large forming force is required. At the same time, it belongs to the local cold bending technology. The plate is not constrained enough in the process of processing, and the plate is easy to shake, which is not conducive to processing. The method of using cla...
