4, the cylinder blank that insulation is finished takes out in heating furnace by discharging machine, and the automatic centering function by manipulator is positioned over down the center of hammering block to cylinder blank again, and regulates vertical centering.
5, press unlatching main piston cylinder carries out the jumping-up distortion to blank, and the biscuit thickness behind jumping-up reaches technological requirement.
6, under the non-return situation of principal post plug cylinder, keep restriction, open the 1250t hydraulic cylinder that liquidates simultaneously, punching pin and following punching pin are carried out punching the biscuit that jumping-up finishes blank.
7, the 1250t hydraulic cylinder below the operation is return, and drives down that punching pin is retracted into the home position, and going up punching pin simultaneously continues downward feeding, up to remaining gross weight core material is washed out, and is clamped by the long hook of artificial use that hammering block goes out 10 taking-ups of gross weight mouth under the jumping-up.
8, all hydraulic cylinder all is retracted into the home position, the compacting of flange biscuit and punching combination process process finished, and blank melts down waiting temperature and gos up to go up to the initial forging temperature Ring Rolling Machine and carry out essence and roll over shaping.
As shown in Figure 8, early stage of the present invention, the basis was: the inner plunger that 1250t is installed in the plunger rod of the body center pillar plug cylinder of 5000t hydraulic press, the position at the center of hydraulic press workbench centrally aligned principal post plug cylinder is installed the plunger of a secondary 1250t more simultaneously, circular jumping-up hammering block is installed respectively on entablature and lower table then, be provided with the circular port that manufactures with the 1250t hydraulic cylinder in the middle of the hammering block, be used for installing down the punching pin of punching.The cylindrical blank that heats is placed on down on the circular hammering block, hydraulic press is suppressed biscuit with 5000t pressure then, wait to reach the requirement height dimension after, master cylinder stops to press down, at this moment, start the hydraulic cylinder of two 1250t up and down, two punching pines that liquidate that promotion is installed carry out punching, after punching finishes, punching pin returns to the plane concordant with the hammering block working face, and master cylinder is return simultaneously, the compacting of whole biscuit and finish in punching combination process process one fire time.
The invention has the beneficial effects as follows:
1, provides the ring base of high-quality for smart rolling on the numerical control Ring Rolling Machine of wind power flange is shaped, guaranteed that smart wind power flange ring yield rate of rolling over shaping improves more than 20%;
2, shortened traditional jumping-up punching technology necessary operations time greatly, traditional method of operating on average needs 25-35 minute operating time, and the present invention only needs 4-6 minute, and efficient has improved more than 80%;
3, the inferior heating again of two fire has been avoided in the minimizing significantly of operating time, save energy resource consumption and raw-material loss greatly, improved stock utilization, increased substantially last product efficient, improve the performance of product, guaranteed the security reliability of wind-powered electricity generation equipment.
4, labour intensity is little, has saved manpower, and operating process is simple and easy to control, easily cylinder blank is positioned over the hammering block center.
