Abstract
The invention discloses a method for manufacturing a knife edge angle detecting tool, and belongs to the technical field of knife edge angle detecting tool manufacturing. The method comprises the steps that raw materials of the knife edge angle detecting tool are prepared; plates are sheared into square stocks with a plate shearing machine for standby application; plate blank is preliminary machined; the knife edge angle detecting tool is subjected to heat processing, the hardness after heat processing is HRC 40-46; the knife edge angle detecting tool is deep machined; the knife edge angle detecting tool is formed in a linear cutting mode, a sector notch is formed at the edge of the outer circle of the tool in a linear cutting mode; the tool is subjected to tempering in a box type furnace with the temperature of 400 DEG C; the knife edge angle detecting tool is further deep machined; and the knife edge angle detecting tool is subjected to chroming and polishing. The knife edge angle detecting tool is obtained by the fact that the plate blank is subjected to machining, heat processing, linear cutting, chroming, polishing and the like, the manufacturing method is simple and reliable, the manufactured knife edge angle detecting tool can meet the batch detecting requirement, detecting accuracy cannot be affected by site and environment, and the method has high practical value.
Description
technical field [0001] The invention belongs to the technical field of knife-edge angle detection tools, and more specifically relates to a method for manufacturing a knife-edge angle detection tool. Background technique [0002] The blades used for machining are mechanical blades, which are widely used and of various types. The types of blades mainly include metallurgical machinery blades, slitting and slitting blades, rubber machinery blades, leather machinery blades, papermaking machinery blades, pipe cutting machinery blades, slitting machinery blades, carton machinery blades, dotted line blades, flower-shaped blades, round Blades, bars, and some odd-shaped blades. For cutting tool and cutting tool processing enterprises, it is necessary to check the processing content of the blade one by one in each link of production, and the detection of the angle of the knife edge is the most important thing in all inspections. [0003] In general, for the detection of the angle of...
