![]() ![]() The tool guide pins and bushings need to be robust enough to overcome these lateral forces. Remember, every tool and press has some lateral play, which in turn affects stability and tooling life. Balance the tooling forces under the press ram. The goal is, by design, to have the tool naturally want to close evenly on all four corner die stops. Balance All Work Being Done in the Tool and in the Press If you are forming with spring-loaded punches, calculate the force required and double it to prevent punch backup as the die closes. If by design you are doing work as the stripper closes, the lifters must sufficiently clamp the die strip under the pilots and against the stripper face plate to maintain a consistent part. Make sure the space between the lifters is not so big that it allows the strip to sag. The strip needs to be parallel through the entire press cycle. Design Lifters as Needed to Keep the Strip Level in Progression and Level as the Die Closes ![]() Carbide is like concrete it will disintegrate before it wears. ![]() Less movement results in less shock and vibration. Reduced die stroke yields reduced ram speed relative to strokes per minute. This helps minimize the die stroke and imparts better dimensional stability to the strip because of less movement and tool component travel and wear. Stagger your cutting punches and minimize strip lift. ![]()
