Convolution Bending Machine

This machine is specially designed for producing convolution-shaped heater tubes. The mould is driven to revolve by speed-reducing electric gear. The mould is driven to hoist or lower by split nuts silk pole mechanism. The air-driven compacting mechanism coils and processes the tubes into pagoda shape, and at the end the air-driven ejector mechanism finishes the stripping step. The whole machine is automatically controlled by electric relay. Shift production (8 h) exceeds
