特徴とするダイクツシヨンの予備下降装置。 A lower mold cushion pad 2 provided near the lower mold 2 installed on the bolster 1a of the press body 1
A is elastically supported by the dictation 4 via the dictation pin 3, and a hydraulic cylinder 13 is provided between the coupling cylinder 4 of the dictation 4 and the pin holder 5 to urge the pin holder 5 upward. Hydraulic cylinder 14 that urges downward
and supply hydraulic pressure to these hydraulic cylinders 13 and 14 via servo valves 17 and 19, respectively, and an upper mold 2 that descends together with the slide 20.
The servo valve 19 is controlled to supply a flow rate to the hydraulic cylinder 14 to achieve a sliding speed at the pin touch position where the pin holder 1 collides with the lower cushion pad 2a, and the pin holder 5 is forcibly pulled down. Preliminary lowering device for the dictation.
