The Center for many Lightweight Production Technology (ZLP) inside of the German Aerospace Center (DLR, Augsburg) is tasked with developing tender carbon fiber phone case reinforced plastic (CFRP) houses in the area and economic production methods focused on industries including aerospace, wind utilities and automotive. Researchers there hunt for automated processes utilizing robotics in addition to technologies for cost-effective and tougher manufacturing with high quality.
To help discuss this goal, Wickert Presstech (Landau in der Pfalz, Germany) has attained a multifunctional composite press the DLR featuring high-temperature heating and cooling platens, an infrared heating system and a switch system which transports components of the infrared oven into the press while the plant's loading and unloading traits. The press also uses a seite an seite platen control for maximum finickingness, achieving a tolerance of zero. 025 mm during the pressing act. Integration of additional path measurement having resolution of 1 µm on the mechanic tool itself will facilitate high-precision formulation, and controls offer a choice about 'press path measurement' and 'tool path measurement'.
The ZLP can be developing a new production cell for many processing complex thermoplastic fiber impur to aid research into automated formulation technologies for CFRP components. Wickert has designed its new touch to enable maximum flexibility for searching for a wide variety of processes and parts. Them reports that the ZLP is aiming so that you consolidate and reform thermoplastic matrix CFRP materials, including high-performance thermoplastics such as polyetheretherketone (PEEK). "The plant's great flexibility is definitely a major benefit of in the processing of all materials applied in today's composites applications, " states that Stefan Hertel, WICKERT design property management company. "Also, studies, simulations and tests have significantly improved the approach geometry and flow design of the actual heating and cooling platens. And because we have a nicely efficient and economical solution for many water cooling, we have achieved especially high cooling gradients and computer cooling tolerances when compared with our previous processes.... the DLR's standards for the variotherm process required us to take newbie, different approaches and to continue constantly pushing developments forward in this field. very well
WICKERT proposed an upper memory press, type WKP 4400 Ohydrates Composite. A wide variety of optional packages incorporated into the press enables processing backyard garden materials, such as PEEK or PPS. The press features a 1, 300 x 1, 200 mm heating and cooling platen, a pressing force regarding 4, 400 kN and a shortest pressing force of only 1 / 4 kN. Heating platen temperatures may also be controlled precisely between 40°C in addition to the 450°C. Maximum tool weight are often as much as 12, 000 kilos, and the maximum transfer time received from initial movement to complete press closure/maximum pressing force is five a few moments.
Its experience in the construction regarding presses for pharmaceutical applications lets WICKERT to comply with clean site specifications, including hydraulics that are practically free of oil mist and dependably prevent contamination of CFRP stages.
For this installation in the Technology Orée of the ZLP, an existing infrared cooker has to be integrated into the press friut. As part of the adapting process, WICKERT can be converting the existing ZLP infrared systems and extending it to meet the requirements regarding future production tasks. The infrared oven will be integrated into the production keep on top of system via a PROFIBUS interface in addition to the visualized via WIN CC-Flex. At the same time programming and visualization are custom-made for the DLR so that process représentation and sequences can be defined around close consultation with the responsible property managers.
In addition , the system will feature a passcode exchange with a linear axis bot already present in the ZLP make it possible for fully automated process implementation. WICKERT is developing an interface the signal exchange between its touch and the robot, resulting in a control systems with programmable functions for most possible flexibility in process sequences. Their selector switch allows manual in addition to the automatic operation or set up, while the press is equipped with a photoelectric screen as a precautionary measure for as the robot operates in the security zone. Software package to adapt the robot tecnicalities for component transfer from the infrared oven to the press is also included in the WICKERT service package. In general, lightweight designed to be fail-safe to EN HEL|OOK|1ST|MAAR|EN L?NG|POR OTRO TANTO, EN|TILL EXEMPEL|N?GON|RICOS|ABUNDANTES|TROFEO}} 289, including the infrared oven. The actual DLR research mandate also should need measurement of energy consumption for comparison of the economic efficiency of various act sequences. Thus, power consumption in each cycle or total power conservation can be measured and logged.
So as the press is commissioned well and quickly, ZLP staff heading trained during WICKERT's commissioning act in production-equivalent conditions. WICKERT can often conduct follow-up training after ordering is complete.
At the DLR web in Augsburg, WICKERT will provide this telephone service — including communicate diagnosis with designated contact person's — to enable rapid implementation regarding processes and machine settings for many complex tasks. This facilitates rapid corrections, quite common when starting up beyond system. The 'tool' for this features, which covers help with operator guidance, act optimization and fault detection, will be the remote servicing function via a high-geared network link between the WKP.
WICKERT views itself as a press research pioneer in the field of composite processing in addition to the believes the WKP 4 100 S Composite will stake newbie ground in composite production. "We are proud that we can develop in addition to the construct this press for the ZLP of the DLR, " says reserving director Stefan Herzinger. "The outcome of our presses in aircraft in addition to the automotive construction shows that we can the actual most stringent requirements and can create the basic conditions for the future production regarding quite new composite components. The advantages of lightweight structures will continue to nurture and WICKERT is already providing complex and yet proven production solutions because of this. "
