Problems solved by technology

During use, the two endpoints of the arc at the top of the sawtooth teeth are Figure 5 The point A and point B shown in the figure are very easy to wear or chip during the cutting process, thus changing the actual cutting position of the sawtooth and affecting the sawing effect of the saw blade
Therefore, at present, the cutting life of the saw blades ground by radial feeding is far less than that of new blades in actual use.

Embodiment Construction

[0021] The method of the present invention can be used for grinding metal cold and hot cutting circular saw blades of various tooth types, and the process is as follows: a. The saw blade to be ground is installed on the grinding machine, and the installed saw blade can rotate freely without hindrance. b. see Figure 4 , select the grinding wheel 1 that matches the sawtooth 2-1 profile of the saw blade 2 to be ground, and install the grinding wheel. c. The grinding wheel rotates to grind each saw tooth of the saw blade to be ground one by one. When grinding each saw tooth, the feeding direction of the grinding wheel is along the axial direction of the saw blade to be ground; see figure 1 , the position of the grinding wheel 1 relative to the sawtooth 2-1 before the axial feed should meet the following requirements: the K point with the closest distance from the outer circumference of the grinding wheel to the sawtooth is located on the extension line L of the tooth root of the...

Abstract

A metal cold hot cut circular saw blade sawtooth grinding method belongs to the metal processing technical field and is used for solving the problem that a sawtooth grinding radial feed method can cause tipping or easy wearing of arc at the blade of the sawtooth. The method includes the following steps: a, a saw blade to be ground is installed, and the installed saw blade can freely rotate; b, a grinding wheel matched with the sawtooth type of the saw blade to be ground is selected and installed; c, the grinding wheel rotates to grind each sawtooth of the saw blade to be ground one by one, and the grinding wheel feed direction is along the axial direction of the saw blade to be ground during grinding; d, the sawtooth type after grinding is checked, and the saw blade is discharged after meeting technical requirement. In the method of the invention, the sawtooth is ground by the grinding wheel in axial feed manner, the sawtooth blade and root after grinding are in straight line, thus eliminating tipping or easy wearing of sawtooth caused by arc at the blade, effectively improving sawing effect of a repaired saw blade and prolonging the service life of the saw blade.

Description

technical field [0001] The invention relates to a cutting tool grinding method, in particular to a metal cold and hot cutting circular saw blade sawtooth grinding method for sawing rolled steel products such as pipes, profiles, bars, etc., belonging to the technical field of metal processing. Background technique [0002] Metal circular saw blades are indispensable and efficient cutting tools in modern steel rolling enterprises, suitable for sawing rolled steel products such as pipes, profiles, bars, etc. The production process and types of circular saw blades have formed a mature technical system after long-term practical application and development. The existing circular saw blade tooth types mainly include rat teeth, triangular teeth, and wolf teeth. During the sawing process of the saw blade, with the increase of the sawing area, the wear degree of the saw teeth is gradually intensified. When the passivation of the saw teeth makes the sawing unable to proceed normally, t...
