冲压件材料的硬度检测,其主要目的就是确定购入的金属板材退火程度是否适于随后将要进行的冲压件加工,不同种类的冲压件加工工艺,需要不同硬度级别的板材。用于冲压件加工的铝合金板可用韦氏硬度计检测,材料厚度大于13mm时可改用巴氏硬度计,纯铝板或低硬度铝合金板应采用巴氏硬度计。
The main purpose of hardness testing of stamping materials is to determine whether the annealing degree of the purchased metal sheet is suitable for the subsequent stamping process. Different kinds zhuzaojg.37ix.com.cnwww.baodingyasi.cnwww.bdkongyaji.com.cnwww.jinzhongbanjia.cnof stamping www.baodingjiaju.com.cnwww.hupomuju.com.cnprocess require different hardness levels of sheet metal. Aluminum alloy sheet used for stamping can be tested by Wechsler hardness tester. When the thickness of material is more than 13mm, it can be changed to Barkholder hardness tester. Pure aluminium or low hardness aluminium alloy sheet should be used Barkholder hardness tester.
在冲压件行业里,冲压有时也称板材成形,但略有区别。所谓板材成型是指用板材、薄壁管、薄型材等作为原材料进行 塑性加工的成形方法统称为板材成形,此时,厚板方向的变形一般不着重考虑。
In the stamping industry, stamping is sometimes called sheet metal forming, but it is slightly different. The so-called sheet metal forming refers to the forming method of using sheet metal, thin-walled tube, thin section as raw materials for plastic processing, which is collectively called sheet metal forming. At this time, the deformation in the direction of thick plate is generally not taken into account.
