There are two times in a press cycle to mechanically feed the terminals. One is during the upward motion of the crimp tooling and the other is during the downward motion of the crimp tooling. In a bench type application wherein an operator will hand present the wire end to the terminal applicator, it is important for the terminal to already be positioned in place over the crimp anvil awaiting the presentation of the wire end. In other words, the terminal is stationary and provides a target for operator wire positioning. Therefore, the terminals must feed on the upstroke after crimping the previous terminal.
Bench applications require an upstroke cam.
In an automatic type application, the wire processing machine automatically positions the wire into the terminal applicator and then must remove the crimped terminal out of the applicator. In this case, it is desirable to provide both an unobstructed area over the anvil and sufficient time to swing the wire in and out of the crimping area. Automatic applications use a downstroke cam. Given this, the applicator cam profile must be matched to the terminal press stroke. Return to FAQ list.
