摘要
一种激光焊接金刚石锯片的刀头包含负责切削的工作层、与基体焊接的非工作层以及工作层与非工作层中间的过渡层组成,为实现此刀头在自动冷压条件下无过渡层的冷压生产,同时保证其能够达到所需强度要求,通过设计一种工作层与非工作层的连接处为凹凸结合结构的刀头,并与常规自动冷压及包含过渡层的手动冷压刀头进行对比。实验结果表明,相比较常规自动冷压,通过该方法能够有效提高工作层与非工作层的连接强度,但与包含过渡层的手动冷压相比仍具有一定差距,但已能够满足使用需求,同时该刀头能够实现自动冷压生产,并且不同尺寸设计具有进一步提升强度的可能性。
The cutter head of a laser welded diamond saw blade consists of a working layer responsible for cutting, a non-working layer welded with the matrix, and a transition layer between the working and non-working layer. In order to realize the cold pressing production of the cutter head without transition layer under the condition of automatic cold pressing, and to ensure that it can meet the strength requirement. In this paper, a concave-convex structure of the cutter head is designed for the connection between the working and non-working layer, which is compared with the conventional automatic cold pressing and the manual cold pressing cutter head including the transition layer. The experimental result shows thatcompared with the conventional automatic cold pressing method, this method can effectively improve the connection strength of the working and non-working layer, but there is still a certain gap compared with the manual cold pressing cutter head including the transition layer. However it can meet the requirements of use, and the cutter head can realize automatic cold pressing production, and has there is the possibility for different size design to further improve the strength.
