Abstract
PURPOSE:To obtain a forging part of good shape by providing a blank sensing sensor on the pressurizing face of a sub-die and performing the braking control of the sub-die based on the signal of the blank sensing sensor. CONSTITUTION:When a blank 4 is pressurized by a punch 5 and die 6, a space part 10 is caused without the contact of the blank 4 with the blank sensing sensor 11 which is provided on the pressurizing face of a sub-die 7, then a signal is turned ON and the signal generating a underfil part is transmitted to a control panel 16 through lead wires 12, 13. The signal stopping the lift of the subdie 7 is transmitted from the control panel 16 by this signal and only the punch 5 starts to ascend gradually. The blank 4 is thus stopped at the sub-die 7, having missed escaping and flows into the space part 10 caused between the sub-die 7 and punch 5. when the space part 10 is eliminated, the blank 4 is brought into contact with the sensor 11 and a signal is turned OFF, and the ascent of the punch 5 and sub-die 7 is started again. When the space part 10 is caused again a signal is turned ON, the pattern is repeated and the product having no underfill 10 can be obtd.
