Spiral Blade Cold Rolling Mill

The spiral blade cold rolling mill is fabricated from high-quality, thickened steel plates that are precision-welded to ensure a robust structure, exceptional durability, and long service life. It delivers high dimensional accuracy and superior surface hardness, making it well suited for high-speed, continuous operation. The machine runs smoothly and stably, with minimal vibration and low noise levels.

Products Description

The spiral blade cold rolling mill is a specialized machine designed to continuously roll strip steel into spiral blades. It is mainly used for manufacturing various types of spiral blades using strip steel as the raw material.

The continuous forming spiral blade cold rolling mill features a tapered roller design and forms spiral blades through a cold rolling process, replacing the traditional cold drawing method. By precisely adjusting key parameters such as roller offset, feeding height, rolling pressure, and guide wheels, the equipment can shape strip steel into spiral blades of different sizes and specifications. It offers the advantages of high precision, stable performance, and efficient production.

A single set of continuous forming rollers is capable of producing spiral blades in multiple specifications, ensuring uniform thickness and minimal dimensional deviation.
