我厂Q11-1.2×100型剪床所用的整体长剪刀片(见图1),材料为T8钢。经锻造、正火、刨、钳加工后,转热处理淬火。要求硬度HRC55～60,全长挠曲度不大于0.25毫米。此刀片采用水淬油冷,即水油分级淬火方法达到要求硬度值。但淬火后变形较大。像这样厚而硬的刀片校正至要求变形量是很困难的。我厂无井式中温电炉和盐浴炉。就利用一般的箱型电炉,采取一系列有效措施,使刀片
I plant Q11-1.2 × 100 type shear used in the overall long scissors (see Figure 1), the material is T8 steel. After forging, normalizing, planing, pliers processing, heat treatment quenching. Requires hardness HRC55 ~ 60, full-length deflection of not more than 0.25 mm. This blade uses water-quenching oil cooling, that is, oil-water classification quenching method to achieve the required hardness value. However, deformation after quenching larger. It is difficult to calibrate a thick and hard blade to the required amount of deformation. I plant no pit temperature furnace and salt bath furnace. On the use of the general box-type electric furnace, take a series of effective measures to make the blade
