Technical Field
The invention relates to the technical field of band saw blade manufacturing, in particular to a tooth tip inserted band saw blade.
Background
The existing bimetal band saw blade is formed by welding and compounding a back material and a tooth material by using electron beams (or laser), machining a tooth shape by using a milling machine or a grinding machine, dividing teeth and carrying out integral heat treatment. There are the following disadvantages:
first, the saw blade must be factory produced or reworked.
Secondly, because the back material and the tooth material are not the same material, the temperature process can only be compromised when the whole body is subjected to heat treatment, and the respective best performance can not be exerted.
Failure in the event of one of wear of the teeth or breakage of the backing means that the blade needs to be reworked or scrapped.
Another existing technique, which is to perform the connection by welding (welding or soldering), has the following disadvantages:
first, the saw blade must be factory produced or reworked.
Secondly, because the welding is hot working, there is processing deformation, and the precision is not high, needs the grinding sawtooth to guarantee the precision.
The high temperature at which the saw tooth support is welded during welding can cause the material to temper and the strength of the saw tooth support to decrease. Failure in the form of either tooth wear or backing breakage means that the saw blade needs to be reworked or scrapped.
Therefore, the saw blade in the prior art is difficult to maintain, has strong requirements and limitations on materials, and has high scrapping cost.
