Problems solved by technology

[0006] ① The roughness of the rake face is large
[0008] ②Width (i.e. equal height) changes greatly
[0010] ③ Tooth tip burrs are large
However, the cost of this solution is very high, resulting in high product prices, which are usually difficult for customers to accept

Embodiment Construction

[0048] A method for manufacturing a band saw blade, the specific process of which is as follows:

[0049] 1) The steel belt is subjected to tooth forming treatment, and the required tooth shape is processed on one side of the steel belt. This processing method can adopt milling forming, grinding forming, punching and shearing forming or other numerical control forming methods, such as: laser cutting, wire cutting, etc.

[0050] 2) The band saw blade that has been formed by the teeth is cleaned to remove surface oil, and then it is kept at 1100°C-1250°C for 0.5-5min, and then quenched to room temperature. Then after tempering at 520-650°C for 5min-120min, cool to room temperature and repeat tempering for 3-6 times. If there is camber in the heat-treated steel strip, it can be adjusted by rolling straightening after heat treatment. Sandblasting or shot blasting can be done if there are surface imperfections, or if the surface needs to be finished to make it aesthetically pleas...

Abstract

The invention discloses a band saw blade manufacturing method and a band saw blade. The band saw blade manufacturing method comprises the steps of S1, subjecting a steel band to tooth forming; S2, subjecting the steel band subjected to tooth forming to thermal treatment; S3, grinding front face and back face of the band saw blade subjected to thermal treatment so that the front face and back face satisfy Ra <0.8 Mum; S4, subjecting the band saw blade that is ground to tooth passivating to remove tooth tip burrs and to form round corners or terraces at tooth tips; S5, subjecting the passivated band saw blade to tooth dividing to obtain the non-ground band saw blade. Direct entry in conventional sawing phase without grinding is achieved, and the low-efficiency grinding step is omitted.

Description

technical field [0001] The invention relates to a band saw blade manufacturing method and the band saw blade, belonging to the band saw blade manufacturing field. Background technique [0002] Such as patent CN103357958A; In the sawing process of US7908954B2, there are mainly problems in the following aspects at present: [0003] 1) In the early stage of sawing, it is necessary to adjust the feed speed and operating speed of the band saw blade to lower than the parameters of the conventional sawing stage for sawing (about 50% lower), which is the so-called running-in stage. Through running-in, the chipping of the tooth tip of the band saw blade can be reduced, thereby reducing the vibration during the sawing process and prolonging the service life of the band saw blade. After a certain period of running-in, adjust the feed speed and the operating speed of the band saw blade to the parameters of the conventional sawing stage for sawing. Because the sawing speed in the runni...
