Problems solved by technology

[0008] For the horizontal sawing of super-large cross-sections, especially when sawing stainless steel, problems such as tooth punching, tooth pulling, non-wear resistance, and skewing are likely to occur
The invention provides a multi-chip band saw blade, which makes the thick and thick chips in the prior art thinner, reduces the cutting force during cutting, and cooperates with the anti-wear tooth shape design to make the sawing life longer and avoid There are problems such as cutting skew, heart digging, cutting immobility, and cutting resistance caused by excessive tooth tip wear

Embodiment Construction

[0028] The present invention will be described in further detail below with reference to the accompanying drawings.

[0029] see Figure 1-5 , a multi-chip type band saw blade, including a saw blade body (back material) and a saw tooth located on the saw blade body, 15 saw teeth arranged in sequence form a main tooth group, each main tooth group includes a first sub-tooth group, a second Sub-tooth group, third sub-tooth group, fourth sub-tooth group, fifth sub-tooth group; each sub-tooth group includes first sawtooth, second sawtooth and third sawtooth arranged in sequence, and the first sawtooth is Straight teeth, the second and third teeth are left sub-tooth and right sub-tooth respectively; the first sub-tooth group, the second sub-tooth group, the third sub-tooth group, the fourth sub-tooth group and the fifth sub-tooth group The order of arrangement of the groups is not limited and can be arranged in any order without affecting the number or size of the chips or cutting ...

Abstract

The invention discloses a multi-chip band saw blade. The band saw blade comprises a saw blade body and saw teeth located on the saw blade body, 15 saw teeth arranged in sequence form a main tooth set,and each main tooth set comprises a first sub-tooth set, a second sub-tooth set, a third sub-tooth set, a fourth sub-tooth set and a fifth sub-tooth set; and each sub-tooth set comprises a first sawtooth, a second sawtooth and a third sawtooth which are arranged in sequence, the first sawtooth is a straight tooth, and the second sawtooth and the third sawtooth are separately a left dividing toothand right dividing tooth. By controlling the different heights of the teeth and controlling the tooth dividing amount, the tooth profile divides a chip into 18 chips during cutting, and the tooth profile can remarkably reduce cutting force in the cutting process and the cutting force in the saw cutting process; and the problems of oblique cutting, core digging, immovable cutting, intolerance to cutting and the like caused by excessive abrasion of tooth tips are avoided.

Description

technical field [0001] The invention relates to a multi-chip band saw blade, belonging to the field of sawing metal tools, in particular to a cemented carbide band saw blade for cutting ultra-large section workpieces. Background technique [0002] In the stainless steel industry, with the improvement of the quality of stainless steel in my country, the consumption of stainless steel related products in China needs to be updated and upgraded, which has stimulated the demand for high-end stainless steel products. Rail transportation such as high-speed rail and subway, as well as the constantly upgraded transportation facilities such as ships and pipelines, will drive the continuous expansion of the demand for stainless steel. [0003] As rough machining of stainless steel, especially martensitic precipitation hardening stainless steel, it is very difficult to machine. In the process of processing, for super-large section stainless steel, the main reasons are that the tooth ti...
