Description
Method field:
The invention belongs to vehicle body fittings field, particularly relate to a kind of production method of power transmission shaft.
Background technology:
In prior art, the step of the production method of power transmission shaft is generally: first carry out shaping stock by common casting process; Finally by shaping for cast turning.But due to the cast that stock is common, material structure and crystal density loose, easily affect the quality of product, therefore yield rate is lower, and cost is high.
Summary of the invention:
The present invention is directed to the production method that above problem provides the more senior lower-cost power transmission shaft of a kind of yield rate.
The present invention overcomes the above problems technical scheme used: the production method providing a kind of driving member, and it comprises the following steps:
1) adopt water atomization to obtain powder of stainless steel and carry out mold pressing, isostatic cool pressing system under 0.5 ~ 1kPa pressure, the time is 2 ~ 4h;
2) isostatic cool pressing base sinter molding in a vacuum furnace at 1315 ~ 1355 DEG C of temperature;
3) by step 2) shaping blank tack and turning on instrument lathe, make and meet step 5) stock of die of press;
4) by step 3) stock in high temperature 600 ~ 800 DEG C annealing, temperature retention time is 12h, when stove is as cold as below 200 DEG C subsequently, air cooling of coming out of the stove;
5) by step 4) stock after process forcing press on that bigger diameter end is carried out cold extrusion is thick;
6) by the stock centering on instrument lathe after thick for pressure, and after centre bore reaming, chamfering is carried out, turning subsequently to the centre bore of bigger diameter end and end face angle, then chamfering is carried out to the centre bore of miner diameter end;
7) by step 6) workpiece that processes punch press on the process of cold-extruded spline is carried out to the centre bore of the nearly bigger diameter end of miner diameter end;
8) subsequently on instrument lathe by step 7) the rough turn plane of end face of workpiece bigger diameter end that processes carry out chamfering;
9) again on instrument lathe by part car long for workpiece miner diameter end except and chamfering after rough turn plane;
10) on numerically controlled lathe, turning is carried out to the cylindrical of the bigger diameter end of workpiece, the shape needed for car becomes, and groove is cut to the position of miner diameter end periphery proximal end face, chamfering is carried out to the centre bore of miner diameter end simultaneously;
11) on numerically controlled lathe by step 10) workpiece that processes carries out flat head chamfering and is finished product after expanding endoporus.
Described numerically controlled lathe is high-precision numerically controlled lathe.
After adopting above method, the present invention compared with prior art, owing to adopting powder metallurgical technique to instead of original casting process, it is less that allowance can stay, and eliminates the activity time of a large amount of equating surpluses, and save raw material, and owing to being carried out cold extrusion forming again after powder metallurgical technique, the structure of material and crystal density are all higher, constant product quality, therefore yield rate of the present invention is higher, and cost is lower.
