[0002] For the large integral top cover due to its huge volume and weight, it is difficult to achieve one-time forming by the current free forging process. The current integral top cover is to form a hollow annular cylinder first, and then form a hollow annular cylinder with the inner diameter The same barrel-shaped body with an open upper end and a closed lower end, the outer diameter of the barrel-shaped body is smaller than the outer diameter of the hollow annular cylinder, and then the lower end of the hollow annular cylinder and the upper end of the barrel-shaped body with an open upper end and a closed lower end are welded together to form a belt Integral top cover with flanges, so that the welds are easy to crack, unsafe and unstable to use

Embodiment
[0020] Embodiment: a kind of molding process method of integral top cover, its steps are as follows:
[0021] a. Billet making: after the riser is removed from the high-temperature steel ingot, a distributed extrusion process is used to form a barrel blank 1 with an open upper end and a closed lower end;
[0022] b. Flange upsetting: The flange upsetting process is divided into multiple upsetting, followed by the first upsetting: the center of the upsetting upper die 3 is aligned with the center of the upsetting lower die 2, and the upper side wall of the barrel blank 1 is just accommodated. In the longitudinal annular opening 31 of the upsetting upper die 3, the upsetting upper die 3 moves downward to the set position, so that the side wall of the barrel blank 1 forms an annular protrusion 11 along the upper end of the outer wall of the upsetting lower die 2; Second upsetting: the center of the second upsetting upper die 6 is aligned with the center of the upsetting lower die...

The invention discloses a molding process method of an integral top cover and an upsetting mold thereof. The high-temperature steel ingot is distributed and extruded into a barrel body blank and then fixed in the upsetting lower mold. In the annular opening, the upsetting upper die moves downward to make the barrel body blank form a ring-shaped protrusion on the upper end of the outer wall of the upsetting lower die, and the plastic upper die moves downward to level the inner surface of the barrel body blank, and finally The upper end of the annular protrusion formed on the side wall of the barrel blank is just accommodated in the annular forming opening of the forming upper die, and the forming upper die moves downward to squeeze the annular protrusion of the barrel blank into a circle of set specifications. Shaped flange, the overall top cover formed by this process is integrally formed, without welds, cracks, safe and stable; the upsetting lower die of the upsetting mold for the integral top cover is a barrel-shaped cylinder with an open upper end, and the upper end surface of the side wall There is a circular arc transition between the inner side wall and the lower end of the upsetting upper die.
Description
technical field [0001] The invention relates to a metal processing process method and related molds, in particular to a forming process method of an integral top cover and an upsetting mold thereof. Background technique [0002] For the large integral top cover due to its huge volume and weight, it is difficult to achieve one-time forming by the current free forging process. The current integral top cover is to form a hollow annular cylinder first, and then form a hollow annular cylinder with the inner diameter The same barrel-shaped body with an open upper end and a closed lower end, the outer diameter of the barrel-shaped body is smaller than the outer diameter of the hollow annular cylinder, and then the lower end of the hollow annular cylinder and the upper end of the barrel-shaped body with an open upper end and a closed lower end are welded together to form a belt There is an integral top cover with flanges, so the welds are easy to crack, and it is not safe and unstab...
