Embodiment Construction
[0053] figure 1 , figure 2 a and figure 2 The mold buffer device 10 shown in b is composed of a normal-pressure air buffer device 12 installed on the press machine 11 and arranged under the backing plate 13, and combined with the lower part of the lower mold 14 arranged on the backing plate 13. The friction die buffer 15 constitutes. Reference numeral 16 is a supply system for supplying and circulating lubricating oil which also serves as cooling oil to the friction die cushion 15 . figure 1 The left side of is the state that the slider of press machine 11 is rising, and the right side is the state of falling. exist image 3 , Figure 4 It is the same in a. The press machine 11 is composed of a frame 18, the above-mentioned backing plate 13, a slider 19 that moves up and down, and a known slider driving mechanism (not shown) that drives the slider up and down.
[0054] The air cushion device 12 includes a multi-stage bellows 20, air (pressurized air) filled inside, ...
