Gear is one of the most widely used mechanical parts in mechanical transmission. For a long time, gear processing required specialized equipment and tools, long machining route, and complex process. So, low processing efficiency, high cost has been the main disadvantages of gear processing. With the rapid growth of automobile and motorcycle production, market competition has intensified. Now the demand for gear has increased, plus the variety, specification, precision, strength, and gear cost. This situation has put forward higher requirements.
Precision forging, temperature extrusion, cold extrusion, and hot and cold composite extrusion are widely used in gear forming technology. But cold extrusion forming stands out from all these forming technologies.
It offers high production efficiency, material saving, low cost, high part strength, precision, and good surface quality. Cold forging has been widely used in gear processing of medium and small modules and specification sizes in the automotive and motorcycle industries.
Cold extrusion technology started late in china. Plus, the long-time research on the cold extrusion technology concept of forging gear, results have taken many detours. But with the improvement of mold technology, especially the application of advanced manufacturing technology such as CAD/CAM technology, precision processing technology, special processing technology, and coordinate measurement technology, it has been able to produce high-precision, high-precision molds to meet the requirements of gear forming accuracy. So, we have no problem with the correct design of the gear cavity and cold extrusion molding process.
