五金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。stampingmaterialhardnesstesting,themainistodeterminewhetherthepurchaseofmetalsheetannealingissuitableforsubsequentstampingpartsprocessing,differenttypesofstampingprocessingtechnology,theneedfordifferenthardnesslevelsoftheplate.薄板：锯削时尽可能从宽面锯下去，若必须从窄面锯下时，可用两块木垫夹持，连木块一起锯下，也可把薄板直接夹在虎钳上，用手锯作横向斜推锯，使锯齿与薄板料接触的齿数增加，避免锯齿崩裂。Thinplate:sawingasfarasaswideaswhensawing.Ifmustbesawedfromnarrowsurface,itcanbeheldbytwowoodenblocksandsawedtogetherwithwoodenblocks.Thesheetcanbeclippeddirectlytothevise,andahandsawisusedasatransverseobliquesawtoincreasethenumberofteethcontactedwiththesheetmaterialand***oidthecrackofthesawteeth.五金冲压模具的安装是否正确合理，不仅影响五金冲压件的产品质量和精度，还会影响模具的工作寿命及生产安全。并且熟练掌握冲压模具的安装也是每个冲压工应该掌握的技巧。Whethertheinstallationofthemetalstampingdieiscorrectandreasonable,notonlyaffectsthequalityandprecisionofthemetalstampingparts,butalsoaffectstheworkinglifeandproductionsafetyofthedie.Andskilledinstampingdieinstallationisalsoaskillthateverystampingworkershouldmaster.)
