Häufige Fragen zur Fertigung: Double-wound spring cotter pin (similar to DIN 11024)
You can produce Double-wound spring cotter pin (similar to DIN 11024) on the FMS-Q 80 RS and FMS-Q 120 RS. The FMS-Q 80 RS works with 80 kN punching force, strip material up to 50 mm width, wire up to 4 mm. At up to 400 parts per minute, the machine is designed for series production — finished parts come straight off the machine.
The radial design positions the bending slides freely through 360° around the central bending core — ideal for parts like Spring cotter pin with multiple bends in different directions. Tool changes take less than 30 minutes, so even smaller batches are economical.
Spring steel wire 1.4310 (ø 0.8 mm) runs through the punch-bending machine as strip or wire stock in a progressive process: punching, bending, and inspection happen in one pass. Instead of buying parts from suppliers, you produce them in-house at significantly lower unit costs from medium quantities upwards — Biegema configures the machine specifically for your part.
