The helical gear Forging Technology of single oil groove, is characterized in that, comprise following processing step:
1., blanking: arrange corresponding raw material weight on cutter, allowance control is between ± 10g, and cutter blanking, then carries out shearing sub-material by cutter;
2., heating: by intermediate frequency heating to 1000-1200 DEG C, temperature must not be too high and too low, and the too high meeting of temperature causes product burning, and the too low meeting of temperature causes product not enough;
3., base: with 1000T friction press base, blank diameter is less than mold cavity diameter 2-3mm;
4., be shaped: be shaped with 1000T friction press, before being shaped, forging is first by after mould and die preheating 10-15min, then blank after preheating is put in mold cavity and forges, and it is more than 800 DEG C that blank final forging temperature controls;
5., hot piercing: pierce punch diameter carries out design and manufaction by the minimum of a value of hole size, and punching counterdie die cavity diameter 0.3mm larger than forging die cavity diameter, then carries out punching with 200T punch press;
6., trimming: excise unnecessary overlap with 200T punch press, adopt pneumatic mode to be blown off by waste material forge piece while excision;
7., isothermal normalizing: with net belt type constant-temperature oven by carrying out isothermal normalizing process, until interior tissue reach regulation require after, stop heating;
8., ball blast: Shot Blasting is carried out to forging surface with apron type airless shot blasting machine;
9., half finish turning: with numerically controlled lathe, polishing processing is carried out to two of forging planes, ensure thickness one to property, and the forging depth of parallelism ensures within 0.05mm.
10., cold punching oil groove: drift and the jig of choosing band oil groove, be then installed on 200T punch press, mix up punching machine stroke, directly rush oil groove.
rough turn: to carry out rough turn by regulation fineness to forging with numerically controlled lathe, then carry out spraying antirust oil, finally pack, single oil groove helical gear required for the present invention can be obtained.
The invention has the beneficial effects as follows: in the present invention, the applicant, for above-mentioned existing issue, has carried out technical study and improvement, determine by cold punching oil groove technique, oil groove directly to be rushed out, after punching, oil groove meets process requirements, simplifies production technology, save production cost, improve production efficiency.
