Product Overview

The Roller Forging Machine is a metal forming system that uses a pair of forging rolls rotating in opposite directions to apply continuous compressive deformation to a billet. Through controlled plastic deformation, the billet is extended longitudinally while reducing cross-sectional area, forming high-quality forgings or forging blanks.

Unlike traditional impact forging, roll forging is a gradual and continuous deformation process. Most metal flows along the length direction under pressure, making it especially suitable for shaft parts, stepped shafts, slab rolling, and long-axis forgings.

Roll forging can be used as:

• A blank-making process before die forging

• A primary forging process

• A direct forming method for long forgings

The process combines the advantages of forging and rolling, offering high dimensional precision, superior mechanical properties, and excellent production efficiency.

Features & Benefits

1. High Precision & Superior Surface Quality

• High dimensional accuracy

• Low surface roughness

• Near-net shape forming (reduced machining required)

2. Optimized Metal Flow Structure

During roll forging, metal fiber structure follows the contour of the forging instead of being cut, resulting in:

• Uniform internal structure

• Improved mechanical strength

• Better fatigue resistance

3. Continuous & Efficient Production

• Continuous rotation process

• High production efficiency

• Easy automation integration

4. Lower Equipment Tonnage Requirement

Since deformation occurs progressively and only part of the billet contacts the die at any moment, the required equipment tonnage is significantly lower than traditional forging.

5. Long Die Service Life

• Static pressure deformation

• Minimal sliding between die and metal

• Reduced wear and extended tool life

6. Stable Operation

• No heavy impact or vibration

• Improved working conditions

• Simple equipment structure
