Four-column hydraulic machine is mainly used for multi-purpose machine tools, internal combustion engines, electrical appliances, bearings, washing machines, cars, general motors, air conditioning motors, stepper motor industry. Pressure has mounted on the shaft parts, plastics, powder products, pipeline assembly function. Main features: 1, this machine uses four-post three-plate kind of open space, a four-poster with precision linear bushings, high stability, may be suitable for processing of different products, the size of its working height and working area, the actual per customer request. 2, hydraulic power systems use high-pressure pumps, hydraulic circuit specifically designed to reduce standby power consumption of, to achieve energy saving, stable performance, low noise, small horsepower requirements, output, speed, stroke can be adjusted, but also based on customer requirements, changes to circuit design, to work purposes. 3, the hydraulic power system is a standard built-in ease of maintenance, maintenance, optional water cooler, hydraulic oil temperature slowly, less failure, high efficiency, long operating production, long service life. 4, the hydraulic cylinder rise height (adjustable finger stroke cylinder) by a limit switch positioning and adjustment nut with the cylinder and a timer circuit, according to different working properly adjusted can play a very high efficiency. 5, security design comprehensive, hands, with an emergency button and move up and down mode, easy installation and calibration abrasive; can be based on customer-specific installation of photoelectric safety protection. 6, the bottom of the desktop stand are equipped with casters, it can be portable mobile machines, energy efficient. 7, another increase in the heating module and the upper and lower temperature control box (for the production of hot trademark, brand, etc.). Product output has 50-500t choose from, optional installation. Machine audience before additional buffer tank or stripper tank, countertops additional automatic back wheel, automatic feeding or withdrawal feeding device; clamping cylinder device, the body may be additional slide guides can accept the specified manufacturing.
