Deliver to and coordinate with bottom frock at lathe, while delivery sheet resets under the effect of feeding gear motor, wait next feeding；It is located at
Hydraulic jack on lathe promotes hydraulic stem to press top frock, and upper frock dnockout core moves down the pipe promoted in the frock of top
Elbow is moved down, and the power of ball pin that pipe bend overcomes continues to be displaced downwardly to lower frock dnockout core, and under pressure, in the frock of bottom
Back-moving spring is compressed, and upper frock dnockout core matches with lower frock dnockout core and is encircled into the shape of pipe bend and pipe bend is realized to press from both sides
Hold, then the cutterhead on lathe is processed to pipe bend, completion of processing, hydraulic jack drives hydraulic stem to reset, back-moving spring
By the lower upward jack-up of frock dnockout core, moved on lower frock dnockout core and above push away pipe bend, while upper frock dnockout core is acted in return spring
Pipe bend is above pushed away and moved between ball pin and upper frock dnockout core in the power and continuation for overcoming ball pin by lower upper shifting, lower frock dnockout core, plus
The good pipe bend of work resets in the presence of push-pull arm, when being reset to the feed opening top of workbench, linear electric motors action, upwards
Jack-up push-pull arm, moves on push-pull arm in the dynamic top frock of shipper pole, return plate is touched down with the top board of feed mechanism mounting bracket
Push back a plate, upper frock dnockout core is moved down and promotes the pipe bend for processing to move down the power that overcomes ball pin and depart from top frock, is fallen into
Feed opening, completes a processing for product.
