The invention relates to a device for automatically
cutting a
pipe fitting, which comprises a feeding mechanism, a clamping mechanism and a
cutting mechanism, wherein the feeding mechanism comprises a sliding clamp die and a feeding cylinder, the sliding clamp die of a clamping
pipe fitting is driven by a sliding clamping cylinder, and the feeding cylinder drives the sliding clamp die to slide; the clamping mechanism comprises a fixed clamp die and a fixed clamping cylinder, the fixed clamp die is capable of clamping the feeding mechanism to be fed to the
pipe fitting, the fixed clamping cylinder drives the fixed clamp die to clamp the
pipe fitting, and the fixed clamp die and the sliding clamp die are arranged in juxtaposition; and the
cutting mechanism is located at the outer side of the fixed clamp die in juxtaposition and comprises an upright fixed seat, a main shaft head, a motor, a lifting oil cylinder and a saw blade, wherein the saw blade is fixed at the main shaft head and driven to rotate by the motor, the main shaft head is slidably fixed on the upright fixed seat through a sliding seat, and the sliding aiming at the
pipe fitting is controlled by the lifting oil cylinder. In the invention, the operations, such as feeding, clamping, fixing, cutting, discharging, and the like of the
pipe fitting can be automatically realized, and the
processing efficiency of the pipe fitting is improved.
