UPBD 1000-8\n旋转弯曲试验机适用于测试钢丝/弹簧钢丝及其他线形试样用UPBD 1000-8对线材进行旋转弯曲试验
当高应力弹簧元件承受动态载荷时，为了安全设计，必须知道材料的非相应疲劳强度。

在初级材料的制造过程中，从生产电线开始，然后从中生产出弹簧，例如用于汽车工业的弹簧。现在的困难在于评价材料因冷加工而产生的行为。因此，为了表明整个过程中的质量，必须对材料进行中等测试，例如导线。

UPBD 1000-8 - for testing highly stressed spring elements
为了防止弹簧的塑性变形，弹簧钢的强度必须很高。因此，疲劳强度分析需要为应用量身定制的测试技术，这确保了不可靠的结果。由于定期质量保证测试的要求和大量的测试，这必须既快又划算。

这是通过UPBD旋转折弯机达到的

8个测试站为同时直径介于1\nmm而且10毫米最大弯曲应力达到1000兆帕。由于在高达> 4000 rpm的高转速下的圆周弯曲负载，在短时间内实现了大量的循环。

因此，UPBD代表了一种高效的测试解决方案，在串行生产中是必不可少的。一些国内和国际客户已经依赖于我们的解决方案。

PRODUKTINFORMATIONEN ANFORDERNRotating bend testing on wire material with the UPBD 1000-8
hen highly stressed spring elements are undergoing dynamic loading, the corresponding fatigue strength of the material must be known for a safe design.

During the fabricating processes of the primary material starting with production of wire, and later on the springs are produced therefrom, which e.g. are used in the automotive industry. The difficulty now lies in the evaluation of the material behavior due to the resulting cold work. So, to indicate the quality along the complete process, the material must be tested middling, e.g. as a wire.

UPBD 1000-8 - for testing highly stressed spring elements
he strength of the spring steel must be very high in order to prevent plastic deformation of the springs. The fatigue strength analysis therefore requires testing techniques tailor-made to the application, which ensures reliable results. Due to the requirement of the regular quality assurance test and the high number of tests, this must be both fast and cost-effective.

This is achieved by the UPBD rotating bend machine with up to

8 test stations for the simultaneous testing of wires with diameters between 1 mm and 10 mm with maximum bending stresses of 1000 MPa achieved. Due to the circumferential bending load at high speeds up to > 4000 rpm, a large number of cycles are achieved in a short time.

Thus, the UPBD represents an efficient test solution and is essential in serial production. Several national and international customers already rely on our solution.Rotating Bending Testing Machine UPBD 1000-8
