Advantage of the present invention or good effect show:
The present invention adopts double-crankshaft structure or flywheel slide block mechanism, makes the movement locus of the existing constant speed helix (spiral of Archimedes) of moving knife cause for gossip, thereby make the moving knife mouth carry out 360 ° around blank, radially shears gradually.
Because the moving knife mouth is to carry out 360 ° around blank radially to shear, make and cut blank along even circumferential stress, otch can not produce oblique angle or the angle of collapsing, and blank can not produce yet and lose the circle distortion.
, around the blank high-speed revolution shearing, make that to be cut blank incision material sharply tired due to the moving knife mouth, otch crackle rapid diffusion, thus reach the purpose of high efficiency, low energy consumption.
Because its cardinal principle is shearing motion, so without waste of raw materials.
Blank is axially retrained, make blank be subjected to the effect of three-phase unequal stress, thereby can shear the very little blank of draw ratio.
