Multiple Composite Rare Earth Tungsten Electrodes Swaging String Object of The Invention To Play Equipment and Technology and Their Characteristics

Multiple composite tungsten electrodes swaging process strings play equipment technical problems , multiple composite tungsten electrodes swaging equipment technology invented string playing the main purpose is to adapt to multiple composite rare earth tungsten electrodes mechanical properties of materials , the use of string playing techniques to achieve efficient processing of tungsten materials , multiple composite tungsten electrodes swaging string playing equipment technology invented by two of the same model using the same frequency, the same speed rotary forging machine (B201-B201, B202-B202) string playing devices consisting of multiple composite rare earth tungsten electrode material B202 , B201 stages of processing , wherein :

( 1 ) First, the first heating furnace 1, the second heating furnace 4 heated to 1450 ~ 1500 ℃, and after the swaging through B203 diameter Φ6.5 polyhydric composite rare earth tungsten electrode material to rate 2 ~ 3m/min fed rotary hammer device starts playing string processing ;

( 2 ) In the B202 stage three times to go through processing , process systems as :

First: the first rotary hammer machine 2 optional Φ6.0 mold ; second rotary hammer machine 5 matching Φ5.6 mold ; first furnace, the second furnace temperature is set to : 1450 ~ 1500 ℃;

Second: the first rotary hammer machine matching Φ5.2 mold ; second rotary hammer machine matching Φ4.8 mold ; first furnace, the second furnace temperature is set : 1400 ~ 1450 ℃;

The third way: the first rotary hammer machine matching Φ4.4 mold ; second rotary hammer machine 5 matching Φ4.1 mold ; first furnace, the second furnace temperature is set to : 1400 ~ 1450 ℃;

( 3 ) In the B201 through two sub- processing stage , the process system is :

First: the first rotary hammer machine matching Φ3.9 mold ; second rotary hammer machine matching Φ3.6 mold ; first furnace, the second furnace temperature is set : 1400 ~ 1450 ℃;

Second: the first rotary hammer machine 2 optional Φ3.3 mold ; second rotary hammer machine 5 matching Φ3.0 mold ; first furnace, the second furnace temperature is set to : 1350 ~ 1400 ℃; through the above processing can get Φ6-Φ3 diverse composite rare earth tungsten electrode material .
