Electric cutting device of cold-bending molding machine

一种冷弯压型机电动切断装置

Abstract

本发明涉及冷弯压型机,是一种冷弯压型机电动切断装置。它包括机架,龙门架,下刀板,下刀片和电动切断装置,龙门架立柱垂直固定在机架上,下刀板和下刀片固定在角座上,电动切断装置包括电动减速机、主轴、若干偏心轮、连杆、上刀板和上刀片,偏心轮偏心套装在主轴上,连杆的上下两端分别与外径装有轴承的偏心轮的轴心和上刀板固定连接,构成曲柄连杆机构,电动减速机带动偏心轮旋转使上刀片向下运动切断物料。进一步改进,本发明还包括上刀片导向装置,上刀片间隙调整装置,下刀片平整度、平直度调整装置以及推料装置。本发明,因为采用电机驱动偏心轮带动上刀板上下运动完成切断工作,不再需要液压系统,因此结构简单,成本低。
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, aportal 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 bladeare 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 eccentricwheels, 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.
