| titleOfInvention | The manufacturing process of interior trapezoidal grooved ring shape part |
| abstract | The invention discloses the manufacturing process of interior trapezoidal grooved ring shape part, its technique is as follows: blanking → forging base is rolled over the processing of ring → annealing → finish turning, be characterized in: (1) is forged base rolling ring process and comprised that the first base of forging and just base rolling encircle two operations, first use upper punch and low punch punching, make just base; Then first base is carried out to conventional rectangle rolling, blank in the middle of making; Re-use main mould, the special-shaped core roller of rolling of abnormity to the rolling of middle blank abnormity; (2) in annealing, interior trapezoidal grooved ring shape part blank at normal temperatures, with 130～155 DEG C/time speed be warming up to 400～500 DEG C, be incubated 2～4 hours, then air cooling. Its advantage is: manufacturing process of the present invention has adopted rational processing step and mold tooling, mechanical performance and the dimensional stability of trapezoidal grooved ring shape part blank in having improved, reduce the difficulty of finish turning processing and the consumption of raw material, improved production efficiency, reduced production cost. |
