Whether for electromobility, aviation technology or safety systems in motor vehicles: A versatile test unit should not only fulfill their purpose, but also work efficiently and cost-effectively. To optimize such a device, Sonplas has in one of their latest developments Clamping elements from the house ACE Shock installed.
Founded before 25 years ago, the Sonplas GmbH from Straubing today as a leading supplier of assembly and testing systems turnkey special machine solutions. Through an in-house R & D department, the company is able to constantly meet the latest technical requirements in the market. "Especially when decelerating drives, we are always happy to rely on the products of ACE shock absorber GmbH from Langenfeld. First, they are high quality, innovative and versatile. Secondly, the service is what we want it to be: straightforward and goal-leading, "says Lukas Sepaintner, design engineer at Sonplas.
Thus, the company also relied on its proven supplier for the construction of a modern testing unit for industrial use. "So far, ACE has mainly supplied us with small shock absorbers and industrial shock absorbers. Due to the special requirements of a current test unit, these components were out of the question in this case ", the designer describes the initial situation and continues:" Since I knew that clamping elements could theoretically solve our problem, I had a look at the homepage of ACE , to which I contacted directly Andreas Otto from the product management of ACE. "
Clamped test unit as ideal solution
In this new case, we first communicated with ACE by e-mail. It was about supporting the electrical drive of the test system. He sets a test head to a defined level, "adds Lukas Sepaintner.
After reaching the specified path, the servo motor of the drive switches off so that the test head can no longer move. To keep it really safe in this position, then the clamping units are operated. Next, the component to be tested is supplied with pressure, so that an opposing force of approximately 5 kN arises. After about 30 s continuous test, the pressure is switched off. This eliminates the drag. Then the clamping units are released and the electric drive returns to its normal position.
The test head itself is guided over two carriages. The waves that travel through the clamping units, serve only to hold the force. They are attached to the probe with a kind of coupling and thus dependent on its tolerances.
Default 1,5 million clamping operations
Since this test unit is used in all areas that Sonplas supplies and is designed for 120 testing operations per hour, a clamping element should be found in the portfolio of ACE, which can not only apply the necessary forces, but also at least 1,5 million clamping operations before Exchange guaranteed.
In addition, a clamped weight of 40 kg had to be considered. The subsequent design showed that clamping elements of the type "Locked PN63-20-2-6B" are ideal for the application. With holding forces of 3600 N and a holding torque of 35 Nm, they operate at a working pressure of 6 bar much more effective than eg. As hydraulic clamping systems, and at the same time lower system costs.
Smaller space saves space
For Sonplas this means not only the desired effective clamping, but also that the drive of the test system could be made smaller, which saves space and space. Between first contact and the successful implementation were in this case only a few weeks.
The uncomplicated interaction of the two suppliers proves to be profitable for large branches of the industry. ACE fully met Lukas Sepaintner's expectations: "Like us, our customers are fully satisfied with the entire special design, from the test unit to its clamping elements."
