YOUR TRAINING AS A
TECHNICAL PRODUCT DESIGNER
A technical apprenticeship offers you a wide range of career opportunities in the industry.
DRIVING INNOVATION FORWARD
As a Technical Product Designer, you will play a key role in ensuring that we continue to improve our products. Creativity, technical understanding and spatial imagination play a decisive role in this.
In the field of machine and system design, your task is to design components, assemblies or entire systems.
THE BIG PICTURE
You will work closely with our development department. You will develop detailed design plans based on modern CAD systems. Your tasks will include checking dimensions for production, including the implementation of desired changes, as well as considering economic aspects. Other aspects of your job include the preparation of plans and parts lists for production and the handling of digital data.
Your top benefits
LONG-TIME ACCURACY GUARANTEED
Our SSM series manipulators run on rails. This and the electrically preloaded drives move the manipulators back and forth and bring them to a halt with the highest precision and accuracy of repeatability.
The unique single-mass concept of the D&D manipulators means that the moving drive and the actuating drive of the tongs are firmly connected. This enables a straightforward, sturdy machine design with very few moving parts and highest-precision control of the moving drive. The drive control is independent from the weight of the forged pieces.
The high long-term accuracy of the tong actuation guarantees that the forging is positioned in the press at exactly the right angle for each stroke.
IN THE PERFECT POSITION – QUICKLY AND PRECISELY
The highly dynamic axial piston motors of the optional ERS system reduce forging times. Because the motors use no throttle valves, there is no compression loss due to throttling. Therefore, the moving drive reaches its final speed earlier and will come to a halt faster.
When compared to the use of proportional valves, this results in up to 20 to 30 percent less time needed for the movements and overall shorter processing times for each forging. In addition the drives for moving the manipulator and those for actuating the tongs can perform various synchronistic overlapping motions. This means that the tongs can be brought in position while the manipulator is still moving, saving additional time with every stroke.
THE MOVING DRIVE
Positioning of the manipulator is performed by backlash-free pin-tooth gearing and therefore, based on the size of the machine, achieves an accuracy of +/- 1.5 to 5.0 mm in the direction of travel.
ACTUATION OF THE TONGS
Turning, opening and closing, lifting and lowering of the tongs are all hydraulically actuated. The vertical-horizontal compensation system “height reset” adjusts the position of the tongs automatically according to the press stroke. Turning the tongs as precisely as possible is crucial for the performance of the entire process. Here our patented valve wear compensation system ensures utmost precision at all times. The long-time stability is extraordinarily high: even after several years of operation the system works just as precisely as on the very first day.
Thanks to our high-precision, permanently stable control system the rotation of the tongs is adjusted exactly to the press stroke.
EFFECTIVE COMMUNICATION
A high-end forging manipulator never operates as an isolated unit. Integrating the machine into the complete process is a basic requirement for maximum productivity. This includes linking with higher-level systems, communication with other process stages and gapless documentation. Our manipulators are compatible with the process control systems of all forging press manufacturers.
The sensors in our manipulators provide comprehensive data and measured values based on which our customers can trace back each individual stroke and prove to their customers at any given time that the supplied forgings comply exactly with the specifications in the order.
The acquired data is used to optimize the process.
STRAIGHTFORWARD DESIGN
DANGO & DIENENTHAL is the only manufacturer of forging manipulators to design the machines with a single central control block for all key hydraulic functions. The hydraulic lines are easily accessible. If necessary the lines can be exchanged quickly and conveniently. When our engineers design a machine, ease of accessibility of all components is a requirement of high priority.
We often hear our customers’ maintenance staff say that they are impressed with the maintenance friendliness of our manipulators. All components are easily accessible thanks to the spacious interior of the machines. That also applies to the pin-tooth gearing which is located on the exterior of the machine for very convenient access.
Furthermore, the axial piston motors that drive our machines require much less frequent maintenance than systems using proportional valves.
The benefits: lower maintenance effort and higher availability.
It's really cool to see how the components that I helped design suddenly become reality and are then installed in our machines.
