Hydraulic numerical control bending machine with auxiliary positioning structure

Abstract

The hydraulic numerical control bending machine with the auxiliary positioning structure comprises a hydraulic numerical control bending machine body, a bending opening is formed in the outer wall of one side of the hydraulic numerical control bending machine body, and a fixing frame is fixedly connected to the position, close to the lower portion of the bending opening, of the outer wall of one side of the hydraulic numerical control bending machine body through bolts; a first inner cavity is formed in the outer wall of the side, away from the hydraulic numerical control bending machine body, of the fixing frame, and a sliding groove is formed in the inner wall of one side of the first inner cavity. According to the hydraulic numerical control bending machine with the auxiliary positioning structure, a plate can adaptively move along with transverse feeding and longitudinal lifting of the plate through transverse movement of the transverse plate in the movable frame and longitudinal movement of the supporting plate in the vertical plate sleeve, so that one side end of the plate can be supported; and the discharging length and supporting stability of the plates are guaranteed, and the problem that the plates are bent and deformed in the discharging process, and consequently positioning dislocation happens to the follow-up bent positions is solved.

Description

technical field [0001] The invention relates to the technical field of numerical control bending machines, in particular to a hydraulic numerical control bending machine with an auxiliary positioning structure. Background technique [0002] The CNC bending machine is to use the equipped mold to bend the cold metal sheet into various geometric cross-sectional shapes. It is a sheet forming machine designed for cold-rolled sheet metal processing. It is widely used in automobiles, aircraft manufacturing, Plate bending processing in light industry, shipbuilding, container, elevator, railway vehicle and other industries. [0003] In order to realize the positioning of the plate during CNC bending machine processing, the Chinese patent "A Hydraulic CNC Bending Machine with Auxiliary Positioning Structure" (Patent No.: 202010856176.2) is equipped with a rotating shaft, a connecting rod and a limit block to perform plate positioning. When feeding, insert the board horizontally into ...
