随着革新活动的开展及新技术的推广,近年来各地逐渐出现了一些比较好的机械夹固式刀具,在有些地方部分地代替了焊接刀片的刀具.看来这种形式的刀具是有推广价值的.对切削工具的要求是有足够的硬度与韧性,在切削过程中有足够的耐冲击性能,有最锋利的刀刃与最合理的几何形状.在满足上述要求方面,机械夹固刀具与焊接刀片的刀具相比,前者在某些场合具有许多特殊的优点. 焊接刀片的刀具,在焊接过程中,容易发现结合不良,刀片上容易出现各种裂纹及缺陷,使用时容易发生脱落或碎裂.焊接时为了获得最大的结合强度,
With the carrying out of innovation activities and the promotion of new technologies, some relatively good mechanical clamping tools have gradually emerged in various places in recent years, and some of the tools instead of welding blades have appeared in some places. Value. The requirements of the cutting tool is sufficient hardness and toughness, in the cutting process has sufficient impact resistance, the most sharp edge and the most reasonable geometry. In meeting the above requirements, the mechanical clamping tool and Welding the blade of the tool compared to the former in some cases has many special advantages. Welding blade tool, the welding process, easy to find bad bonding, the blade prone to various cracks and defects prone to use off or broken Crack. In order to obtain the maximum bonding strength welding,
