Description

嵌式双金属锯带
本实用新型涉及切割材料用的锯带或锯条。
锯带或锯条是锯割金属或其它材料的常用工具，锯齿需要有较高的硬度，而锯带或锯条的母带则需要耐磨和具有弹性，通常采用合金钢、钴系、钨系、钼系高速钢或其它硬质合金做齿尖，采用弹簧钢做母带，然后将齿尖与母带用电子束焊接，由于焊接后需进行热处理，但是因构成齿尖和母带的材料不同，无法找到一个同时适应这两种材料的热处理温度，这样制成的锯条难以同时满足齿尖和母带的性能要求，因此容易产生母带开裂或齿尖硬度差的缺陷。
本实用新型的目的是通过对齿尖与母带形体结构的改进，提供一种可将齿尖与母带预先经热处理，然后采用银钎焊或铜钎焊焊接的嵌式双金属锯带或锯条。
本实用新型由齿尖和母带钎焊构成，齿尖的周围轮廓为梯形或基本接近梯形，齿尖的锐角为40-45度，母带的锯齿边设有镶嵌齿尖的齿穴，齿穴的形状与齿尖根部的形状相配合。
由于本实用新型采用预先经热处理的齿尖与母带进行镶嵌和钎焊，齿尖与母带分别具有各自最佳性能、齿尖与母带的嵌接方便、结合牢固，所制成的锯带或锯条锯割性能好，产品经久耐用。
以下结合附图说明实现本实用新型的最好方式：
附图1是本实用新型的结构示意图；
附图2是侧边有V形槽的齿尖示意图；
附图3是齿尖根部与母带齿穴底部呈折线形的示意图；
附图4是母带的齿穴带有半圆状凹穴的示意图。
附图1所示的齿尖(1)嵌入母带(2)之后，齿尖外翘，齿尖的一边齿刃与母带基线成5-15度夹角，如图1中的α夹角，这样的安置在对齿刃进行磨削时，只需磨削齿尖的一个刃面，可以为使用带来方便；
附图2所示是侧边带有V形槽的齿尖，这种形式的齿尖与母带嵌接更为牢固；
附图3所示是齿尖的根部与母带的齿穴底呈折线状，如图3中的(3)，这样的形式可增加钎焊缝的长度，齿尖与母带结合得更牢；
附图4所示的母带齿穴的边侧或角隅可带半圆状凹穴，如图4中的(4)，这样的结构在齿尖与母带钎焊结合时可熔入焊料加强结合的牢度。
