Roll forging machine 680
Details
ZGD680 Automatic roll forging machine is used to process metal materials, either as a billet making process before die forging, or directly roll forging parts. It transforms the material into the desired shape by rotating and extruding rollers. Widely used in aviation, automobile, construction fields, with advantages of high efficiency, good product quality, and material savings.
Mechanical Principles
A roll forging machine is a metal forming machine that uses two or more rolls to rotate between two fixed supports and bring metal material into the gap between the rolls to change the shape and size of the metal material by continuous rolling and deformation. This type of machine is usually used to produce long metallic materials such as steel bars, tubes, shafts and rods with round, oval or hexagonal cross sections.

Forging Features
● Less workload required
The forming force required for continuous local pressure on the billet is smaller than that of die forging.
● High production efficiency
The productivity of roll forging is significantly improved, which is about 5 to 10 times that of die forging on hammer.
● Less material consumption
The material utilization rate of roll forgings is generally above 80%.
● Excellent inner quality of roll forgings
Good mechanical properties and long fatigue life.
● Good labor conditions
There is no impact when roll forging, vibration and noise are small, labor conditions have been greatly improved, and it is easy to realize automation.
Application
Roll forging machines are used for processing metal materials, which can be rolled, stretched, extended, twisted, etc. They are commonly used to produce metal products such as shafts, rings, wheels, machine parts, etc. They are applicable to various fields, such as：
● FORGED PARTS
● AUTOMOBILE PARTS
● RAILWAY PARTS
● HYDRAULIC END FITTINGS
● SCAFFOLDING FITTINGS
● FASTENERS
● AGRICULTURE PARTS
● MACHINED PARTS
