Servo Transfer
A through-the-window servo-driven transfer system often requires transfer hardware to be mounted on each end of the press, which may prove chal- lenging when working with progressive dies. But such a system is ideal if fre- quent access to the die is required. Transfer-drive mechanisms on both ends and the ability to uncouple the tooling bar ease access.
modular front-and-back systems can provide stampers with the flexibility to address future production needs. Dual-lane production for each system eliminates the need for a second press and utilizes a smaller, more efficient footprint, which can double production output. The full-servo drive system allows for independent control of each axis, production of parts from the right or left side, and the ability to incorpo- rate special tooling orientations or techniques.
Incorporating a U-turn configura- tion in the die line—possible in either type of system—also can eliminate the
need for a second press. A U-turn arrangement allows for finger grips to transfer the part from station to sta- tion, and when a part reaches the end of the first production die line, the part is shifted 90 deg. and is trans- ferred to the second production die line, which runs alongside the first. Since each tooling bar operates inde-
pendently on the X axis, transfer bars move in opposite directions simulta- neously, thus optimizing press loading and throughput.
Given the options in current servo- driven transfer technology, imple- menting a servo-transfer system into an existing press often is a cost-effective solution. MF
