Forging roller is an important tool for metal pressure machining, which usually consists of the following parts: 1. Bearing housing: installed on the frame, used to support the rotation of the entire roller. Housings are usually made of cast iron or steel with sufficient strength and rigidity. 2. Rollers: Rollers are the main part of rollers, which are usually made of high-strength alloy steel. There are usually multiple roller bodies with different contours on the roller shaft for metal pressure machining of different shapes. 3. Roll body: The roll body is the working part on the roller shaft, which is usually made of high-strength alloy steel. The outer surface of the roll body is usually precision ground and polished to ensure its surface smoothness and dimensional accuracy. 4. Roll neck: The roll neck is the connecting part between the roll body and the roller shaft, which is usually made of high-strength alloy steel. The roll neck usually has multiple shoulders wit…
