Abstract
The invention discloses a dispersive type band saw blade. The dispersive type band saw blade is composed of a saw back portion and a saw tooth portion comprising a plurality of repeating units. The distance between tooth tops of two adjacent saw teeth of the saw tooth portion is the tooth diameter P, and the distance between the tooth top portion and the tooth root portion of saw teeth is the tooth height H. Each repeating unit comprises a first saw tooth, a second saw tooth, a third saw tooth, a fourth saw tooth and a fifth saw tooth, wherein the first saw tooth, the second saw tooth, the third saw tooth, the fourth saw tooth and the fifth saw tooth are sequentially and continuously arranged. Through change of the tooth height H and the tooth diameter P, chips are small and can be discharged easily, and cutting resistance is lowered. Through change of the tooth angle theta, cut-in performance of the band saw blade is improved, and therefore pressure on the back portion of the band saw blade from a back pressing block of a tool body can be lowered, the service life of the band saw blade can be prolonged, and the band saw blade is suitable for cutting various medium-diameter and large-diameter materials which are made of tool steel or stainless steel and difficult to cut.
Description
Technical field
The present invention relates to a kind of decentralized bands for band.
Background technology
Stainless machinability is more very different than medium carbon steel.As 100%, the relative machinability of austenitic stainless steel 1Cr18Ni9Ti is 40% with the machinability of common No. 45 steel; Ferritic stainless steel 1Cr28 is 48%; Martensitic stain less steel 2Cr13 is 55%.Wherein, the poorest with the machinability of austenite and austenite+ferritic stainless steel.Stainless steel has following several respects characteristics in working angles: 1, work hardening is serious: in stainless steel, the most outstanding with the work hardening phenomenon of austenite and austenite+ferritic stainless steel.2, cutting temperature height: during cutting plastic deformation and and cutter between friction all very big, the heat in metal cutting of generation is many; Add stainless poor thermal conductivity (thermal conductivity factor be about No. 45 steel～), a large amount of heat in metal cuttings all concentrate on cutting region and the interface that cutter-bits contact, and radiating condition is poor.3, not frangibility, easy bonding of smear metal: stainless plasticity, toughness is very big (especially its percentage elongation of austenitic stainless steel surpasses more than 1.5 times of No. 45 steel) all, it is without stop to add the smear metal in man-hour, what not only influence was cut carries out smoothly, and smear metal also can be squeezed and be hindered finished surface.Under high temperature, high pressure, the compatibility of stainless steel and other metals is strong, easily produces adhesion, and forms built-up edge, has both aggravated tool wear, can occur again tearing phenomenon and machined surface is worsened.These characteristics of the martensitic stain less steel that phosphorus content is lower are more obvious.
Traditional bands for band is that crown is contour, both sides divide the tooth amount identical, tooth angle is identical, cutting for above-mentioned material has the following disadvantages: crown is easy to wear, blade life is low: the affinity interaction in the process that cuts stainless steel, make and produce bonding between tooth-bits, thereby make cutter produce bonding abrasion, add that carbide (as TiC) the particulate hardness in the stainless steel is very high, directly contact with crown during cutting, friction, make the wearing and tearing aggravation, and smear metal is complete, frangibility not, fill up and adhere to roller seating space portion during cutting, cause the bands for band weak heat-dissipating, worsen cutting and regulate, smear metal simultaneously also can injure machined surface.
