Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] see Figure 1-5 , a cemented carbide band saw blade for woodworking, comprising a band saw back material 1 and a hard alloy cutter head 3, the band saw back material 1 includes a plurality of saw teeth 2 arranged at intervals, and the cemented carbide cutter head 3 is welded and fixed to the saw teeth 2 , the design of the band saw blade consists of two parts, one part is the design of the tooth profile, and the other part is the design of the grinding tooth form.

[0029] Design of tooth profile

[0030] See figure 1 As shown, the design of the 1.6Tpi tooth pitch: According to the tooth pitch calculation formula, the tooth pitch of 1.6 equal teeth is 15.88mm, but in the actual sawing process, water waves generally appear in wood processing, in order to better ensure the saw Cutting surface quality, eliminating the influence of water waves, changing...

Abstract

The invention discloses a hard alloy band saw blade for woodworking. The hard alloy band saw blade comprises a band saw backing material and hard alloy cutter heads. The band saw backing material comprises a plurality of sawteeth arranged at intervals, the hard alloy cutter heads are welded and fixed to the sawteeth, the six continuously-distributed sawteeth form one cycle, and the spacing of thetwo adjacent sawteeth within one cycle is gradually decreased or increased in an arithmetic progression mode; the three continuously-distributed hard alloy cutter heads form one cycle, the three continuously-distributed hard alloy cutter heads are correspondingly a first tooth A, a second tooth B and a third tooth C, the first tooth A is delta1 higher than the second tooth B, the second tooth B isdelta2 higher than the third tooth B, and a value range of the delta1 and delta2 is between 0.05 and 0.10mm. Compared with the prior art, lines of water waves can be well eliminated, and the degree of finish of the processing surface is improved; and in addition, through the design of hard alloy teeth, the cutting force of a single tooth is reduced, so that the hard alloy teeth have a wear compensation function, and can adapt to a large processing range.

Description

technical field [0001] The patent of the present invention relates to the technical field of cutting tools for sawing wood, in particular to a hard alloy band saw blade for woodworking. Background technique [0002] At present, the application of cemented carbide band saw blades in the wood processing industry mainly includes 3 equal teeth (13mm wide saw blade), 2 equal teeth (27mm wide saw blade), 2 / 3 teeth (27mm wide saw blade) and 1.3 equal teeth (27mm wide saw blade); Among them, 3 equal teeth means the number of saw teeth per inch, that is, there are 3 teeth in every 25.4mm long saw blade, which can also be expressed by 3Tpi. Similar 1.3 equal teeth means that there are 1.3 teeth in every 25.4mm long saw blade, 2 / 3 teeth means that there are at most 3 teeth and at least two teeth in every 25.4mm long saw blade. [0003] Judging from the current woodworking carbide band saw blade products, they are mainly divided into three categories: single metal band saw blades, bim...
