1985年4月20日至26日在上海举办的国外和香港地区机械工具展览会上,HERTEL公司展出了一种新的切削力自紧装配式切断刀。它除具有结构新颖、设计合理、装夹可靠等优点外,并可节约大量整体式切断刀的刀体钢材,现介绍如下。一、夹紧原理图1为利用切削力自紧装配式切断刀的结构。刀片1是预先加工好的,工作前可将 HERTEL exhibited a new cutting force self-assembly cutting knife at the International and Hong Kong Machine Tools Exhibition held in Shanghai on April 20-26, 1985. In addition to its advantages of novel structure, reasonable design, reliable clamping, etc., and can save a large number of integral cutter blade body steel, are described below. First, the clamping principle Figure 1 is the use of cutting force self-compact assembly-type cutting knife structure. Blade 1 is pre-processed, can work before
