Tight type steel pipe cutting machine

The utility model relates to a machinery dismounting device technical field, especially a tight type steel pipe cutting machine. It includes base, cutting frame, motor and saw bit, and cutting frame swivelling joint is on the base, and the motor is installed on the cutting frame, and the saw bit is installed on the motor, is equipped with constant head tank, clamp plate and strut on the base. Set up clamp plate and forked strut of constant head tank, splayed, two -way fixture inside and outside the formation on the base. During the use, lay the steel pipe in the constant head tank earlier, prevent to roll to the cover is at the front end of strut, then the decline clamp plate makes the both ends of clamp plate push the tail end of strut and the outer wall of steel pipe respectively, and according to lever principle, when the tail end of strut closed up, the front end launched, exerts the power of propping to the inner wall of steel pipe, with the clamp plate cooperation, grasps the steel pipe jointly, has both improved the clamping -force degree, has avoided the steel pipe damage to be out of shape again.
