Forming and Punching machines

Brief Description:

The Schuler GmbH, Göppingen, CSC 1000 servo press in the C-frame design is used for blanking and forming operations on small parts. The individual adjustment of the stroke height using the reversing movement (pendulum stroke) of a torque motor allows for flexible use of the press. Individual adjustment of the slide kinematics to the process parameters allows an adaption of the press to the forming process. The press operation mode is either manual or automatic.

Technical Specification:

Main Areas of Application:

• Investigation on the influence of different process parameters on component quality and tool wear in shear cutting and forming processes
• Continous stroke tests during shear cutting

Equipment:

• EV 132 TM electronic roll feed unit from Zehnder & Sommer GmbH, Witten
• Required drive torque provided via servomotor
• cooling unit for cooling the drive motor
• brake unit for generating the hydraulic energy, for operating the holding brake

Brief Description:

The servo stroke press is used at utg to generate forces on test benches due to its high flexibility. Its bottom center point has excellent accuracy, even when off-center forces are applied. It also has a high level of slide parallelism due to the preloaded roller guides. The nominal pressing force is available over the entire stroke. The stroke is infinitely adjustable.

Technical Specification:

Main Areas of Application:

• Dynamic testing on in-house developed test benches
• Single stroke shear cutting tests

Equipment:

• High-speed camera

Brief Description:

The GRM-NC automatic punching and bending machine has a modular design and essentially consists of a gripper feed, a 400 kN servo press and eight independently controllable servo axes - six arranged radially, two in the depth direction - each with a nominal force of 31 kN. The six radially arranged servo units can be freely positioned within their working range, and the adjustment of the units is automated. In combination with Bihler's standardized LEANTOOL modular tool system, the system and the tool can thus be flexibly and quickly adapted to a wide range of applications.

Technical Specifications:

Main Areas of Application:

• Manufacture of stamping and bent components
• Research on the rebound behaviour of stamped and bent components
• Investigation on the avoidance of slug pulling

Equipment:

• HSB-tool (for research on slug pulling)
• Optibend tool (for rebound research)
• Stamp fatigue test bench

Brief Description:

Freeform bending opens up completely new design options for bending round tubes and profiles. In the process, even high-strength materials can be bent for all radii with low cycle times using only one tube-specific toolset. The radii can be seamlessly connected and positioned in several planes. Freeform bending of different radii without tool change is made possible by the NISSIN principle, in which the tube is first pressed by a feed unit through a guide sleeve and then through a tube-specific bending die. The tube is bent in a spatial curve by translation and rotation of the bending die relative to the guide sleeve. The kinematics' dynamic control produces a transitionless three-dimensional tube geometry with changes in curvature and direction at every point. The bending area's material structure is preserved, which ensures high formability for subsequent processing, for example, by hydroforming. Another area of application for freeform bending is in areas where radii of different sizes characterize the workpieces. Also, large radii that cannot be bent on conventional bending machines can be transformed with high speed and accuracy in a single operation.

Technical Specification:

Main Areas of Application:

• Freeform bending of round steel and aluminium tubes as well as profiles or any cross-section

Equipment:

• Two tools for bending round tubes (42.4 mm x 2.6 mm und 33.7 mm x 2.0 mm)
• A tool for bending square profiles
