Abstract

The invention provides a processing device for a high-precision pipe fitting molding tool. The processing device is characterized by comprising a workbench, an expanding device and a contracting device; an expanding station is arranged at the left side of the horizontal top of the workbench, and while a contracting station is arranged at the right side of the horizontal top of the workbench. The processing device for the high-precision pipe fitting molding tool has the advantages that the structure is simple, and the design is reasonable; the aperture of a pipe fitting to be processed is selected to be 70mm, so that the expanding position is greatly prevented from springback during expanding, and the influence on the aperture of the expanding position is reduced; the contracting is performed by stamping contracting, namely, the pipe fitting is stamped for contracting through a second air cylinder and a stamping die, and therefore, the circumstance of failure of the aperture of the pipe fitting can be reduced, the time of processing and contacting the pipe fitting can be effectively decreased, and moreover, the contracting and expanding can be synchronously performed, and as a result, the process is optimized, the labor cost and energy consumption are saved, and the process operation is sped up; meanwhile, the pipe fitting is vertically fixed, so that the axial position of the pipe fitting is avoided deviation due to the influence of gravity can be avoided.
