1¡¢Adopting three-parts combined machine body and four tensile screws rods with two times nominal force and high pressure oil locking ensure high rigidity. 2¡¢Eccentric shaft adopting four-point support and the deformation of main spindle is slight after strong force.Both main spindle and connecting rod adopt imported heavy duty and precise roller bearing. 3¡¢Slider guide adopting imported linear roller bearing ensure haigh guiding precision and strong anti-eccentric ability.The slider won't diverge in the botton dead center. 4¡¢Eccentric shaft is made of high-strength alloy steel treated by heating and processed by grinding so the ability of bearing strength is strong and it will not deform. 5¡¢It adopts reserved upper-die weight balancing device,reducing the machine'svibration and noise,extending the service life of the dies and improving working environment. 6¡¢Connecting rod regulates screw by hydraulic locking device ensuring the die's normal working in the state of high speed.
