The utility model discloses an end upsetting device, the thickening mould and the clamping mechanism that provide including the interval, the last circular body that is equipped with the pipe end and treats the thickening that presss from both sides of clamping mechanism, the upset end protrusion clamping mechanism of circular body and to the extension of thickening mould, the thickening is equipped with the elongated hole with the external footpath looks adaptation of round tube in the mould, and the one end that clamping mechanism was kept away from to the elongated hole is equipped with a bell mouth, answer the extension that is equipped with the external diameter in the thickening mould of position and is lighter than bore diameter on the circular body with bell mouth path terminal pair, the thickening mould is close to clamping mechanism's tip and the distance between the bell mouth path end is less than or equal to the length that circular body extends clamping mechanism. Guarantee the internal diameter size, realized the one shot forming of pipe end toper portion and the increase of pipe end wall thickness simultaneously, improved pipe end leakproofness and working strength, behind the pipe end processing screw thread, threaded connection's resistance to deformation strength reinforcement has effectively improved life, and improved material utilization rate, machining efficiency is high.
