cold sawing machine is widely used in steel metallurgical plant, especially for special section steel rolling production line as cutting equipment, generally mounted at the back of the rolling mill in sectional work plant finishing line, functioning in head or tail cutting and fixed length cutting on sectional bars after cooling bed or straightening, compared with other cutting equipment, cold sawing machine take more advantages such as simple structure, light weight and high efficiency etc,
cold sawing machine is sorted similar to hot saw machine, in structurally available with slide seated and four-bar linked two categories, upon to the arrangement in the production line is divided into stationary saw cutting machine and movable saw cutting machine according to the main transmission form can be divided into motor-direct passing type and belt-indirect transmission type; depend onto the transverse form can be divided into three kinds, as fixed type, slide plate type and trolley type, based on sawing form can be divided into four-bar linked and toothed bar type etc.
the disc cutting machine nhi designed and developed has 50 years of history. our company has developed a disc saw machine with sawing blade diameter ranges from φ1100 ~ φ1800mm. mobile cold saw blade drive a pair of spiral bevel gears by the ac motor, and feed by hydraulic blade, depending on the cutting section and cutting force, adjustable to the blade feed rate, and referred to sectional bar clamped to the roller bed, also completed by hydraulic device mounted on the saw machine. the whole sawing process can be achieved plc program control, and with reasonable structure, adopted rolling friction and hydraulic feed, ensure smooth and reliable operation.
