The structure of the new-type precision forging die and extrusion die for cylindrical gears was pointed out. And the design of the tool profile of the precision forging die for the gears and the processing method were stated. The cylindrical gear can be completely formed after one-time hammering with the new-type precision forging die on the friction press, without any burrs. After annealing and surface cleaning, the forged gear will be extruded with the new-type extrusion mould on the hydraulic machine for precision adjustment. The precision of the forged gear is prominently improved and the life of the precision forging die increased.Key words precision die forging, gear manufacture, die design, die manufacture”BZ](Jiangsu Institute of Petrochemical Technology, Changzhou 213016)(Jiangsu Institute of Petrochemical Technology, Changzhou 213016) Abstract:Bobillier construction approach for the inflection circle of a four bar linkage is an easy and practical synthesis approach for approximate straight line linkages. Bobillier construction approach and its characteristics was introduced in detail. Two approximate straight line linkages were synthesized using this approach.
