在电机行业的生产中,广泛的采用0.35毫米或0.5毫米厚的Q_(10)、Z_(10)或m_5～m_6等牌号的硅钢片。以往对其冲裁间隙大小的确定是按硅钢片的厚度来确定的,也就是说,不论材质是冷轧、还是热轧,是国产的,还是进口的。0.35毫米的双面间隙均为0.04毫米左右,0.5毫米厚的双面间隙均为0.07毫米左右,对于材料的机械性能及其同一种材料的机械性能各向异性对其间隙大小选择的影响,考虑得就不多了。 例如以上所举出的几种牌号的冷轧硅钢
In the production of the motor industry, a wide range of 0.35mm or 0.5mm thick Q_ (10), Z_ (10) or m_5 ~ m_6 other grades of silicon steel. In the past to determine the size of its blanking gap is determined by the thickness of silicon steel sheet, that is, regardless of the material is cold-rolled, or hot-rolled, is made, or imported. 0.35 mm double-sided clearance of about 0.04 mm, 0.5 mm thick double-sided clearance of about 0.07 mm, the mechanical properties of the material and its mechanical properties of the same material anisotropy on the choice of the size of the gap, consider Not much. For example, the above-mentioned several grades of cold-rolled silicon steel
