Industrial shredder equipment in the production, we all know is to use the blade to cut, motivated will generate heat, heat will be fever, so in production for a period of time must pay attention to the blade temperature, that should be asked to specific the time of this tool production temperature control in the production, has no effect on production, and does not harm our knives? The following:
Industrial shredder blade production temperature requirement: the blade tempering temperature is 240, 10 "C, insulated for 60 minutes, then the oil is cold. Why is this, first quenching the blade at this temperature to temper, can get the hardness HRc56~ 59. The second Cr12MoV steel adopts 1060g 10OC temperature quenching, 240 SGT 10 "C tempering heat treatment process, the dual axis tearing up function gets better impact toughness. For the dual axis shredder device, the first time to deal with 120 blades, of which the knife 6. The blade hardness is HRC60~64, the blade is 100% checked hardness, all hardness is HRC "~ 59". 60 write after quenching blade single warping deformation is less than 30%, conform to the requirements of the cold working process, the other 40% blade plane warping deformation super bad, plastic shredder is in commonly 0.3 mm, we adopt heat straightening after quenching, full control within 0.30 om, 100% inspection after tempering deformation, deformation of 100% qualified.
