增设强压功能。即对卸料镶块压料部加厚尺寸(正常的卸料镶块厚H+0.03mm),紧固件,以增加对凹模侧材料的压力,从而抑制冲切时冲压件产生翻料、扭曲变形。
Additional pressure function. In order to increase the pressure on the material of the die side,紧固件生产, the pressure of the material in the die side is increased by the thickness of the material of the unloaded insert (normal unloaded insert thickness H+0.03mm), so as to suppress the turning and distortion of the stamping parts.
五金冲压件材料的硬度检测,紧固件报价,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。
stamping material hardness testing, the main is to determine whether the purchase of metal sheet annealing is suitable for subsequent stamping parts processing,紧固件哪家好, different types of stamping processing technology, the need for different hardness levels of the plate.
五金冲压件与铸件、锻件相比,具有薄、匀、轻、强的特点。冲压可制出其他方法难于制造的带有加强筋、肋、起伏或翻边的工件,以提高其刚性。秦皇岛五金冲压件由于采用精密模具,工件精度可达微米级,且重复精度高、规格一致,可以冲压出孔窝、凸台等。冷冲压件一般不再经切削加工,或仅需要少量的切削加工。热冲压件精度和表面状态低于冷冲压件,但仍优于铸件、锻件,切削加工量少。
