Multiple composite rare earth tungsten electrodes swaging process string playing devices invented by two of the same model is used , the same frequency and speed of rotary forging machine (B201-B201, B202- B202) consisting of string playing devices multiple composite rare earth tungsten electrode material B202, B201 stage processing , B203, B202, B201 as tungsten and molybdenum in the regular machining processes , typically used for segmentation swaging process , is the use of B-203, B-202, B-201 swaging the swaging machine for processing . B-203, B-202, B-201 rotary forging machine for the device model , B-203 rotary forging machine rotary hammer stroke max , suitable for processing large workpieces ; B-202 rotary forging machine rotary hammer stroke , followed by appropriate machining small parts ; B-203 rotary forging machine rotary hammer stroke minimum , generally used for processing smaller parts. Die change system Φ6 other means swaging touched minimum diameter of 6mm.

Multiple composite rare earth tungsten electrodes swaging process parameters string playing devices formulation is based on multiple composite rare earth tungsten electrode materials developed organizational variation , the process of deformation of the electrode material organizational changes, recovery temperature and the recrystallization temperature is also based on the degree of deformation change so as to avoid multiple composite rare earth tungsten electrode material embrittlement recrystallization , also need to change the processing temperature to keep the temperature in the reply above the recrystallization temperature. Therefore, the equipment and technology to match the technical parameters , and is limited to multi-composite production and processing of rare earth tungsten electrodes , the main advantages of this process are: ( 1 )A process through two rotary forging dies , the original B202 6 step process reduced to three , the B201 process in four steps to reduce the current two , the processing efficiency doubled. ( 2 )Use of string playing techniques , billet machine after the first one rotary hammer forged quickly after entering the next rotary hammer forging machine , to avoid heat loss , and thus economic energy .
