01

Reducing / Expanding presses / Swager

The tube is formed during forming axially by at least two clamping jaws. A guided drawing-in ring or expanding mandrel is pushed into/over the tube and in this way expands/reduces the workpiece. The closed design of the machine housing preferred by GFU ensures that the workpiece can be formed without any problems:

  • Durability of the forming line
  • Consistently high precision of the components
  • Good accessibility of the tools

For necessary multiple operations, we offer an optional automatic tool changer.

Rolling machine

The flow-rolling process is based on the principle of flow-forming. The main difference is that the tool is not a roller that follows a specific shape, but a cup-shaped tool in which the entire shape is incorporated. The components that can be produced using this process must be rotationally symmetrical.

03

Forging machine

The tool segments (2, 3 or 4-jaw tools) exert radial compressive forces on a rotating workpiece. Different workpiece shapes can be achieved by appropriate design of the tool segments. Depending on the degree of forming, this process takes place cold or hot.

The forging process can be used for steels, aluminum, copper, titanium and as well as other metallic materials.

04

Upsetting machines

The upsetting is based on the principle that two tool segments enclose the partially heated pipe and the material is then upset in the axial direction by 1 or 2 punches. Both pipe and solid materials can be partially upset. Contours are possible via the tool geometry.

Bending machines

Flattening and pre-bending of cross-rolled or stretch-rolled aluminum bars is used to reduce the secondary scrap in the production of solid aluminum chassis parts (cars, trucks). The combination of several forming steps (flattening, bending, flattening) in just one movement saves time and money and greatly reduces the amount of flash. Essentially, the component is bent and the two bar ends are flattened within one cycle.
