Description
Technical field
The present invention relates to forcing press accessory field, particularly relate to the improvement that the brake apparatus of flywheel in forcing press is proposed.
Background technology
In prior art, during forcing press braking, usual first disable motor is progressively braked flywheel again; But along with the increase of the tonnage of forcing press, the size of flywheel and quality are also increasing, make the man-hour of the braking of above-mentioned middle flywheel more and more longer, the serious working (machining) efficiency reducing forcing press.To this, State Bureau once disclosed on May 21st, 2014 document that portion is called " punch press flywheel brake device ", application number is " 201210456455.5 ".Propose one in this case and flywheel is completed to the flywheel brake device braked fast and efficiently by " piston rod " promotion " brake body " and then utilization " brake ribbon ".
But people find after reality uses, because inertia during flywheel turns is very big, when therefore it being braked, great turning moment will be produced, and in this case, the motion of piston rod is one along the moving of radial direction of flywheel; Like this, great shear stress will be brought to piston rod when braking it, thus significantly reduce service life and the operation stability of piston rod; Meanwhile, also significantly reduce the service life of brake ribbon, significantly improve use cost.
