Automatic Shaft Straightening Machine: Principles & Features

An automatic shaft straightening machine is essential in industries like automotive, where shaft parts often deform during heat treatment. It restores shafts to their original shape by applying pressure to specific deformation points, ensuring high precision, stable operation, and enhanced efficiency. Let’s take a closer look at its working principles and features.

The machine uses rollers positioned at specific angles relative to the movement of the shaft. Large motor-driven rollers serve as active pressure rollers, rotating in the same direction. Smaller driven rollers rotate through friction created by contact with the shaft.

To apply the necessary pressure on the shaft, these smaller rollers can be adjusted forward or backward, either simultaneously or independently. The more rollers the machine has, the higher the accuracy of the final straightened product. The machine applies forces such as compression, bending, and flattening to straighten the shaft.

The automatic shaft straightening machine is user-friendly, requiring minimal input from the operator. Tasks like loading and unloading the workpiece and pressing the "auto start" button are all that’s needed. The machine automates processes like curvature measurement, straightening point positioning, and pressure application.

High accuracy is a key benefit, with the machine measuring and adjusting curvature automatically. The digital display shows the workpiece’s curvature, offering real-time monitoring. It also includes a safety feature that prevents over-straightening, safeguarding both the workpiece and the operator.

The machine’s user interface is intuitive, with a visual and audible indicator system for quality control. After each straightening cycle, it evaluates the workpiece’s tolerance, signaling if it meets the required standards. With a large database, the machine can store up to 200 workpiece parameters for efficient, quick recall and production setup.
