Abstract
The utility model provides an annular pressing die for a clamping-pressing type pipe fitting, and belongs to the technical field of machinery. The annular pressing die solves the problem that the compression joint effect of an existing annular pressing die for a pipe fitting is poor. The annular pressing die comprises a circular-arc-shaped fixed die and two circular-arc-shaped movable dies. The inner ends of the two movable dies are hinged to the two ends of the fixed die respectively. The outer ends of the two movable dies can be buckled together, and the fixed die and the inner sides of the movable dies form an annular clamping-pressing ring after the outer ends of the two movable dies are buckled, wherein the clamping-pressing ring is used for clamping and pressing the outer side of a pipe fitting and provided with a plurality of evenly distributed clamping-pressing portions. After the annular pressing die is buckled, the contact between clamping-pressing portions and the pipe fitting can be converted from line contact or local surface contact to the situation that the clamping-pressing portions are totally squeezed on the outer side of the pipe fitting. In the compression joint process of the pipe fitting, the contact between the clamping-pressing portions and the pipe fitting can be converted from line contact or local surface contact to the situation that the clamping-pressing portions are totally squeezed on the outer side of the pipe fitting. In this way, at the very beginning of the compression joint process, the pressure exerted on the pipe fitting by the clamping-pressing portions is high; finally, the clamping-pressing portions are totally attached to and squeezed on the outer side of the pipe fitting, and therefore the compression joint effect of the pipe fitting is good.
