ZGD Series Roll Forging Machine

Automatic roll forging machine ZGD series are used for pre-forming of work pieces with diameter maximum 40- 200mm of shaft parts billet, available used for final forging as well.

The automatic roll forging machine can achieve fully automated production, effectively reducing labor costs. Furthermore, compared to traditional forging methods, it boasts higher production efficiency and material utilization rates, resulting in significantly reduced overall production costs.

We can also provide semi-automatic roll forging machine which has no manipulator compared to automatic series. If you need the specifications of the semi-automatic series, please contact us.

Forging Features

High equipment production capacity ( up to 1000 parts/hour)

Favorable structure of material fibers.

Low maintenance costing.

High accuracy and maximum proximity to required dimensions of finished products.

Minimum waste(billet use coefficient is as high as 0.98).

Opportunities to produce a wide product range using the same equipment.

High die life(up to 1,000,000 parts).

Computer numerically control(CNC). A CNC machine can be programmed to control metal processing and give instructions to automatic tools, equipment, and rollers.

PRINCIPLE

The working principle of the roll forging machine is mainly to exert pressure on the metal material through a pair of reverse rotating rollers to produce plastic deformation. During roll forging, the metal billet is placed in the feeding area of the roll forging machine and then rotated by the drive wheel. During rotation, two rollers move towards the center and apply a certain amount of pressure on the billet. This process can be divided into three stages: primary deformation, intermediate deformation and final deformation. The billet is processed by the roll forging machine, and the plastic deformation of the desired shape and size can be precisely achieved.

APPLICATION

APPLICATION

As an advanced plastic forming process, roll forging has been widely used in many industries. In aerospace, automotive, agricultural tools, weapons and daily hardware industries, roll forging process is used to produce various forgings, such as automobile front axle, crankshaft for aircraft engine, connecting rod, engine blade, spade and wrench.

In addition, the roll forging machine can also be used to produce twist drill, knife nail, hoe, pickaxe and other workpieces.

ADVANTAGE

It has a series of advantages such as high material utilization rate, good product quality, good working conditions, easy to realize mechanical automation, high production efficiency and long die life. Compared with ordinary die forging, the machine tonnage needed by roll forging is small. By the way, roll forging machine also needs less fire times, lower labor costs. A single piece can save about 30% of raw material, but obtain accurate size and smooth surface of the billet.
