Automatic R-Shaped Spring Cotter Pin Making Machine

Automatic R-Shaped Spring Cotter Pin Making Machine (R Clips Retaining Cotter Pin Making Machine or R Hitch Pin Making Machine)  is a high-speed wire forming machine designed for producing R-shaped spring cotter pins (R clips, hairpin cotters) with high precision and efficiency. It utilizes a gear-driven cam mechanism to perform continuous wire feeding, bending, and forming operations. This machine is widely used in industries such as automotive, machinery, agriculture, and hardware manufacturing. Automatic Gear Cam Type R-Shaped Spring Cotter Pin Making Machine is an ideal solution for manufacturers seeking efficient, precise, and automated production of cotter pins, ensuring high productivity and consistent quality.

R-shaped spring cotter pins are essential fastening components used to secure shafts, bolts, and other mechanical parts. This machine automates the entire production process, converting steel wire into finished cotter pins through precision forming and bending operations.

The gear cam system ensures synchronized movement of forming tools, providing stable performance and consistent product quality.

Working Principle of R Pin Bending Making Machine

1. Wire Feeding – Steel wire is automatically fed from a coil into the machine.
2. Straightening – The wire is straightened for accurate forming.
3. Cam-Driven Forming – Gear-driven cams control bending tools to shape the wire into R-shaped cotter pins.
4. Cutting Process – The formed pin is cut to the required length.
5. Automatic Output – Finished cotter pins are discharged continuously.
