The utility model provides a keyway type welding tool, including a cylinder matrix and a knife handle. One end of the base is made of a font type convex platform, one side of the knife handle is opened with a type groove, the convex platform of the base is matched with a groove on the handle, and a stress releasing slot is opened on both sides of the groove, the knife handle is common carbon steel and the matrix is hard closing. Gold bar. The new tool used in this new type is simple in manufacturing process and convenient in control; the structure is suitable for the whole hard alloy bit cutter, and the stress releasing slot on the handle of the tool handle eliminates the welding temperature and the thermal expansion rate of different materials to produce stress, prevents cracking, and can also prevent the loss of welding material during welding; it is semi closed during welding. It can be intuitively seen whether the solder is filled or not filled, and it can also avoid the situation that it is not easy to find out when the slag is clamped and the pores are not welded. From the inspection point of view, only the appearance can be observed, and the welding defects can be generally viewed and the detection is relatively simple.

技术介绍
众所周知,硬质合金棒材是由稀有金属元素进入组合配方而形成贵重原材料,现该类材料用途最多方面是整体合金刀具的制造。而在现实生产制造中,对规格比较大(即直径较大)刀具或者要求结构加长的刀具(超常规刀具)不可能完全采用整体硬质合金材料来制造。因为第一,硬质合金价格成本高,是普通刀具材料3~10倍。超常规刀具价格是正常硬质合金刀具材料1~2倍。第二,即使按要求制作成整体合金刀具,其使用效果未必与其昂贵的成本价格成正比。在实际生产应用中,为不将刀具成本放大,常采用普通碳素钢与硬质合金对焊方式来解决成本问题,降低减少使用负担。通常硬质合金刀具焊接结构是刃口部分采用相对硬而耐磨硬质合金材料,非刃口部分采用相对强度性能优良价格低廉的普通制钢作刀具柄部。两者之间有一个能相互连接机构。相互凭借着中间介质有机融合,焊接在一起。一般情况下,具有坚硬的硬质合金材料在机械加工中制成有一凸台元素中央连接结构,与其相对应配合外围部分则是具有韧性较好材料而构成凹榫形状的钢体。随之而来的问题是对焊结构 ...
