GB4334.5-84不锈钢硫酸-硫酸铜腐蚀试验法对试样需作180°成U形或S形弯曲,基于该试样尺寸[(80～100)×20×(≤4)]较短而厚度规格多样的特点,不能直接在材料试验机上实施。后虽有厂家用油压千斤顶改装成专用装置,其实质是油压试验机的缩型,未能摆脱速度慢、支距不能随意调节,而难以适应试样厚度随机变化等不足,不能适应大批量生产检验需要。1988年10月在长城钢铁公司召开的标准修订会期间,仍有不少同行为实现该试样的U形及S形弯曲感到困难。为此,我们自行研制成杠杆式多功能弯曲装置。它主要由组合杠杆式的施力机构、试样限位夹持机构、与水平方向成60。倾角的装配机构组成,并有如下优点。
GB4334.5-84 stainless steel sulfate - copper sulfate corrosion test method for the sample to be made into a 180 ° U-shaped or S-shaped bend, based on the sample size [(80 ~ 100) × 20 × (≤ 4)] is shorter and Thickness and diverse specifications, can not be directly implemented in the material testing machine. Although the factory after the hydraulic jack converted into a special device, the essence of the hydraulic testing machine shrinkage, failed to get rid of the slow speed, the distance can not be adjusted, and difficult to adapt to the random sample thickness changes, can not adapt to large Mass production inspection needs. During the standard revision meeting held by Great Wall Iron & Steel Co., Ltd. in October 1988, many colleagues still found it difficult to achieve the U-shaped and S-shaped bending of the sample. To this end, we developed a lever-type multi-function bending device. It is mainly composed of a combination of lever-type force agencies, sample limit clamping mechanism, with the horizontal into 60. Inclination of the assembly mechanism, and has the following advantages.
