Reduce Roll Machine

Automatic Type

Roller forging machine is a kind of plastic change of billet by means of a pair of fan-shaped dies rotating in opposite direction In order to obtain the forging technology of the required forgings or billets. During the deformation process of roll forging, After the blank is compressed by the roller forging die in the height direction, in addition to a small part of the metal flows laterally, Most of the metal flows along the length of the billet. Therefore, the essence of roll forging deformation is billet The extended deformation process of the material under pressure is applicable to the process of reducing the cross section of the billet, such as the shaft Class parts of the drawing, the slab of the grinding. In industrial applications, roll forging can be used as die forging The pre-blanks process provides blanks for long shaft forgings; Also available on the roll forging machine Realize the main forging forming process or direct roll forging.

Manual Type

Cross wedge rolling refers to the continuous local deformation of the cylindrical billet between the dies of two rolls, which results in the shape of the workpiece and the bottom of the die Partial grooves have the same shape. The type module is mounted on a roller and rotates in the same direction under the drive of the roller to drive the round billet Rotating in the opposite direction, the billet compresses and deforms in the radial direction of the wedge. The shape of the rolled workpiece and the bottom groove of the die Consistent.

Introduction

A Reduce Roll Machine is a forging machine that shapes billets through plastic deformation using a pair of fan-shaped dies rotating in opposite directions. This process helps achieve the desired shape and properties of forgings or billets efficiently.

Working Principle

During the deformation process, the billet is compressed vertically by the roller dies. Most of the metal flows along the length of the billet, with only a small portion moving laterally. This characteristic makes the Reduce Roll Process highly effective for reducing the cross-sectional area of billets, such as shaft components or flat grinding slabs.

In industrial applications, the Reduce Roll Machine is used to prepare pre-forms for die forging of long shaft forgings. It can also perform the main forging process directly, ensuring precision and material flow control for optimized forging operations.

Machine Features of Reduce Forging Technology:

Reduce Roll Forging technology combines the advantages of both forging and rolling, offering high precision, minimal surface roughness, and superior-quality forgings. One of its key benefits is the preservation of the metal’s fiber structure, which follows the contour of the forged part without being cut.

This results in a uniform internal structure, excellent mechanical properties, and eliminates the need for additional machining, thereby preventing flow line cuts or exposure issues.

Key Features & Advantages:

✅ High Precision & Superior Quality – Ensures excellent surface finish and dimensional accuracy.
✅ Enhanced Mechanical Properties – The continuous fiber structure improves strength and durability.
✅ High Production Efficiency – The continuous rolling process enables faster production rates.
✅ Simple & Cost-Effective Setup – Requires minimal workshop space and foundation preparation.
✅ Extended Die Service Life – Reduced wear due to static pressure and minimal sliding between metal and die.
✅ Low Equipment Tonnage Requirement – The gradual and continuous deformation process ensures that only a small portion of the billet is in contact with the die at any given moment, reducing the need for high-tonnage machinery.
✅ Smooth & Stable Operation – No shocks or vibrations, leading to better working conditions and easier automation.
