Background technique
Gas shielded arc welding (abbreviation gas shield welding) has high production efficiency, at low cost, low power consumption and other advantages, in production practice
It is widely used.Meanwhile gas shield welding the disadvantages of that there is also spatters is unstable, appearance of weld deviation.In order to reduce gas shield welding
Spatter loss coefficient, improve weldquality, it is necessary to allow the gas shield welding droplet transfer to become regular.Realizing the most effective approach of this point is
Change the continuous wire feeding mode of traditional constant speed, that is, uses push-pull wire feeding.
Push-pull wire feeding refers to that under wire feed step pitch and the push-and-pull suitable situation of frequency, the droplet transfer in gas shield welding changes
Scrambling when fast wire feed and become " molten drop of step one ", i.e., be sent into every time and all cause first short circuit transition, the frequency of transition
Equal to the frequency of push-pull wire feeding.Since the critical short-circuit condition (like the non-shorting state of short circuit) of moment is acted in mechanical pull-back forces
Under, so that electric arc forms stable molten drop, and regularly it has been transitioned into molten bath, has reached the welding effect entirely without splashing
Fruit.Using plug-type wire feeding mode, i.e. " advance-rollback-advance-rollback " (displacement of the displacement of advance greater than rollback
Amount), current foreign countries can only be realized using high performance servo motor (high-frequency rotates and reverse alternate run).Using servo motor
This mode realized is at high price, it is difficult to realize that market is widely applied.
Has the push-pull wire feeding device of welding wire " advance-rollback-advance-rollback " function, core component is one kind three
Steel ball wire feed chuck (shown in Fig. 1).This collet is mainly led by cylinder casing 1, tapered sleeve 2, spring 3, steel ball retainer 4, welding wire
