Problems solved by technology

[0004] The purpose of the present invention is to provide a high-toughness circular-toothed knife processing technology to solve the problem of insufficient toughness and wear resistance of the circular-toothed blade in the process of processing the circular-toothed blade in the above-mentioned background technology due to the problem of material selection. Insufficient performance, it is impossible to cut iron wire, steel wire and other materials, and the tooth gap will be severely worn during use, and the serious thing is that the tooth gap will break, and the blade needs to be replaced frequently, which reduces the overall practicality.

Abstract

The invention discloses a high-toughness tooth circular cutter processing technology. The steps are as follows: step 1: selecting materials, selecting high-quality spring steel; step 2: rough turning, using a common horizontal lathe to perform simple rough machining on the blank ; Step 3: wire cutting, use a wire cutting machine to cut it, cut out a rough tooth shape, and obtain a rough machining part of the tooth circle blade that is initially formed; Step 4: Mill teeth, use a machining center to mill out the knife edge, and the milling teeth are sharp; Step 5: normalizing, use an oven to eliminate the internal stress at the teeth, and cool in still air after holding for a suitable time; Step 6: quenching and tempering, put the preliminarily formed rough tooth circular knife into the quenching furnace Quenching is carried out internally, and the temperature is slowly lowered by the quenching furnace; the toothed circular knife produced by this process has good wear resistance and toughness, and is suitable for cutting various materials and has a long service life.

Description

technical field [0001] The invention relates to the technical field of tooth circular insert processing, in particular to a tooth circular insert processing technology with high toughness and high wear resistance. Background technique [0002] The toothed blade is made of high-quality spring steel, suitable for papermaking, paper product processing, adhesive tape products, film, wire and cable, rubber, aluminum foil, chemical fiber, non-manufacturing cloth, composite packaging materials, telecommunication appliances, cigarettes, leather, printing, food clothing and other industries. This blade is used in shredders, and requires the minimum toughness of the blade, maximum wear resistance, sharp and durable cutting edge and not too high hardness. In the manufacturing process, due to the requirement of product accuracy, the blade must reach micron-level accuracy. [0003] However, during the processing of this kind of toothed blade used for shredders, due to the problem of ma...
