Zusammenfassung:PROBLEM TO BE SOLVED: To provide a lubricant supply device for a press machine, the device being able to improve work efficiency for set up, by automating connection between a lubricant supply source and a metal-mold-side passage.SOLUTION: A lubricant supply device 5 for press machine comprises a valve seat 71, a valve body 72, a coil spring 73, and a pressing unit 152. The valve seat is provided in slide-side passages 53 and 54 to which lubricant is supplied and which is formed in a slide 2. The valve body opens/closes the slide-side passages by coming into contact with or separating from the valve seat. The coil spring presses the valve body in a direction in which the valve body comes into contact with the valve seat. The pressing unit is provided in a metal mold and, when the metal mold is mounted between the slide and a bolster plate, presses the valve body against the pressing force of the coil spring in a direction in which the valve body is separated from the valve seat. In the metal mold, a metal-mold-side passage 62 that, when the metal mold is mounted between the slide and the bolster plate, is located to face the slide-side passages and communicates with a surface to be processed by press.SELECTED DRAWING: Figure 3 【課題】潤滑油供給源と金型側の流路との接続を自動的に行うことで、段取の作業効率を向上させることが可能なプレス機用潤滑油供給装置を提供する。【解決手段】プレス機用潤滑油供給装置5は、弁座71と、弁体72と、コイルばね73と、押圧部152とを備える。弁座は、潤滑油が供給される流路でありスライド2に形成されるスライド側流路53,54に設けられる。弁体は、弁座に対して着座する又は離座することによりスライド側流路を開閉する。コイルばねは、弁体を弁座に着座する方向に付勢する。押圧部は、金型に設けられ、金型がスライドとボルスタプレートとの間に取り付けられたとき、コイルばねの付勢力に抗して弁体を離座する方向に押す。金型には、金型がスライドとボルスタプレートとの間に取り付けられたとき、スライド側流路と対向し、かつ、プレス加工面に連通する金型側流路62が形成されている。【選択図】図3
