Referring to fig. 1-4, an integral shaping tool for a rolled shaft sleeve comprises a base 1 and a shaping female die 5, wherein two movable cushion blocks 4 which are oppositely arranged are connected to the top end surface of the base 1 in a sliding manner, semicircular grooves are respectively formed in the opposite side surfaces of the two movable cushion blocks 4, and a through cavity 43 is formed after alignment; the movable cushion block 4 positioned at the periphery of the through cavity 43 is provided with a containing groove 41 for placing the shaping female die 5; a discharge hole 12 is formed in the base 1 positioned below the through cavity 43; the die cavity 51 of the shaping die 5, the through cavity 43 and the discharge hole 12 are all coaxially arranged; after the two movable pads 4 are aligned, the inner diameter of the through cavity 43 is smaller than the inner diameter of the cavity 51. The movable pad forms a stop step 42 at the periphery of the die cavity, and the roll sleeve in the die cavity is blocked from continuing to move downwards. Meanwhile, the problem that the shaping force applied when the shaping core rod passes through the inner hole of the shaft sleeve is larger than the static friction force between the female die and the shaft sleeve, so that the shaft sleeve is taken out of the die cavity together by the shaping core rod is solved. After the two movable cushion blocks are separated, the inner diameter of the through cavity is not smaller than the inner diameter of the die cavity, and the rolled shaft sleeve enters the through cavity from the die cavity and finally comes out from the discharge hole.
Specifically, grooves are respectively formed on the inner side wall and the top end surface of the movable cushion block 4, and then the two movable cushion blocks 4 are aligned to form a through cavity 43 and a containing groove 41, wherein the through cavity 43 and the mold cavity 51 are coaxially arranged, and the containing groove 41 is just used for placing the bottom end of the shaping female mold 5. When the movable cushion block 4 moves on the base 1, the gland 6 and the shaping female die 5 are fixedly connected together and then fixed on the base 1 through the supporting rod 7, so that the gland 6 and the shaping female die 5 are fixed.
