Problems solved by technology
[0004] However, the conventional motor drive method requires an external power supply, so there is a problem that it cannot be used in the field where the power supply cannot be supplied. The conventional hydraulic drive method is equipped with a hydraulic pump or a hydraulic oil tank, so there is a problem that the device is large and fixed. Setting type or complex structure for controlling bending angle

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.
Description
technical field [0001] The present invention relates to a portable pipe bender using hydraulic pressure, which does not use a motor and does not require a separate electric supply (power supply), and can be driven anywhere on the site with hydraulic equipment such as a hydraulic pump, so that it can be carried to the site without using a separate electric power supply (power supply). Portable pipe bender using hydraulics that can be used as a work tool and has excellent on-site practicality and mobility. Background technique [0002] Generally, pipe bending devices are divided into mandrel bending devices and mandrel-free bending devices according to whether the mandrel is installed or not. The mandrel bending device has a large volume of the overall device due to the installation of the mandrel, so it has the disadvantage of inconvenient movement. Disadvantages, on the contrary, the non-mandrel bending device has the advantage of being easy to move because of its simple str...
