Electric cutting device of cold-bending molding machine

Abstract

The invention relates to a cold bending moulding machine and an electric cutting device of the cold bending moulding machine is provided. The cold bending moulding machine comprises a machine frame, a portal frame, a lower cutting board, a lower blade and an electric cutting device. The studs of the portal frame are vertically fixed on the machine frame. The lower cutting board and the lower blade are fixed on an angle seat. The electric cutting device comprises an electric speed reducer, a main shaft, a plurality of eccentric wheels, a connecting rod, an upper cutting board and an upper blade. The eccentric wheels are eccentrically sheathed on the main shaft. The upper end and the lower end of the connecting rod are respectively and fixedly connected with the axle centers of the eccentric wheels, the external diameters of which are installed with bearings, and the upper cutting board to form a crank and connecting rod mechanism. The eccentric wheels are driven to rotate by the electric speed reducer so as to lead the upper blade to move downwards to cut materials. With further improvement, the invention also comprises an upper blade guiding device, an upper blade gap regulating device, a regulating device for regulating the flatness and the straightness of the lower blade and a material-pushing device. As the eccentric wheels is driven by adopting a motor to drive the upper cutting board to make up and down movement to complete cutting, the cold bending moulding machine has simple structure and low cost by requiring no hydraulic system.

Description

technical field [0001] The invention relates to a cold-bending forming machine, in particular to a cutting device of the cold-bending forming machine. Background technique [0002] After the existing cold roll forming machine is formed, its cutting device generally adopts hydraulic drive to cut off the plate. For example, the Chinese utility model patent with application number 200620107658.3 discloses a steel structure forming cutting device, which mainly consists of a base with a column and a bottom plate, a belt Cylinder seat of punching cylinder, main slider, upper forming die and adjusting bolt, lower forming die and adjusting bolt, cutting cylinder of cutter slider, upper cutter, lower cutter with adjusting bolt, gear and its meshing The rack and so on. When working, under the control of the control system, the feeding mechanism feeds the material with a set length and starts stamping. When stamping and forming, the cutting oil cylinder does not work, the upper cutte...
