Before reconstruction
・It takes great force to tighten the clamping bolt enough so that it won’t loosen. Also, the point where the lower side of the die and the die block hole connects seizes easily.
After reconstruction
・The clamping bolt is lightly tightened and then locked in place by a gear, so it can be taken off and put on rapidly and with little force. Also, there is no risk of the die loosening by vibration during production, so unmanned production can be safely performed.
・Since it is just lightly locked, the lower side of the die’s connection point doesn’t seize, and an improvement in changeover workability can be measured.
