发明名称 PORTABLE PIPE BENDING DEVICE USING HYDRAULIC PRESSURE
摘要 Disclosed is a portable pipe bending device using a hydraulic pressure which does not use a motor; does not require a separate electricity supply (a power source); and can be driven anywhere on a site where a hydraulic facility such as a hydraulic pump exists to carry the same to the work site to use the same as a work tool to provide excellent on-site usage and mobility. According to the present invention, the portable pipe bending device using the hydraulic pressure comprises: a hydraulic cylinder operated by a hydraulic pressure supplied from a hydraulic drive unit to supply a hydraulic fluid; a forward/backward guide member connected to a piston rod of the hydraulic cylinder to move forwards and backwards, and provided with a rack gear disposed on one side thereof; a drive member having a drive gear installed above a drive shaft, and a pinion gear installed below the drive shaft and meshed with the rack gear; a driven member having a driven shaft on which a bending former is axially mounted from an upper side of a housing, and a driven gear installed in the driven shaft, and meshed with the drive gear of the drive member in the housing; and a control unit to control an operation of the hydraulic cylinder.
