As optimization, the above-mentioned cutting facility frame one side fixed head that is spirally connected, above-mentioned trimming cylinder is screwed onto on the fixed head.
As optimization, be spirally connected on the above-mentioned cutting facility frame and fix a protective cover, the axle head of above-mentioned trimming cylinder is arranged in the protective cover.
As optimization, above-mentioned stationary knife one side has " U " shape groove corresponding with above-mentioned through hole, and above-mentioned connecting pin passes " U " shape groove and is inserted in the through hole.
As optimization, have a blind hole in the above-mentioned cutter groove, be provided with a moving knife top spring in this blind hole, this moving knife top spring one end is provided with a top spring steel ball, and above-mentioned moving knife top spring pushes up cutting blade to stationary knife by top spring steel ball.
Three, the beneficial effects of the utility model
The utility model pneumatic type automatic tangent apparatus solves looper mechanical resistance properties problem and tangent mechanism weares and teares easily, stuck problem, equally can not produce any additional forces to wanting machine yet, finish the workpiece operation afterwards by the disposable thread cutting action of finishing of solenoid control cylinder cutter, this thread cutting device adopts cylinder to connect the trimming blade and once finishes thread cutting action, can reduce again the time waste that manually-operated produces, improve again tangent line efficient.
Description of drawings
