Description

Technical Field

[0001] The utility model relates to the field of metal saw blade grinding devices, in particular to a grinding device used for metal saw blade processing. Background Art

[0002] The processing of metal saw blades generally involves cutting out the approximate shape of the metal saw blade from the profile using laser cutting. Laser cutting uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporates to form holes. As the light beam moves across the material, the holes continuously form narrow slits, thereby completing the cutting of the material. Therefore, after the cutting is completed, some of the metal liquid will melt into liquid due to the high temperature at the slit. After the cutting is completed, it will quickly cool and solidify at the slit of the metal saw blade, forming irregular metal particles. This results in poor smoothness of the metal saw blade teeth, and grinding is required to remove the irregular metal particles solidified at the slit before the metal saw blade can be put into use.

[0003] In the prior art, a saw blade grinder is usually used to grind the teeth of a metal saw blade. The saw blade grinder is composed of a frame, a grinding disc, a guide rail, a slider and other mechanisms. The grinding disc is connected to the transmission shaft of a motor arranged on the frame, and the saw blade is fixed to a saw blade mounting seat arranged on the top of the slider. During grinding, the motor drives the grinding disc to rotate at a high speed, and the operator holds the saw blade and pushes the slider along the slide rail to approach the grinding disc to grind a certain tooth on the saw blade. After grinding, the slider is pushed in the opposite direction to move the saw blade away from the grinding disc and then rotate the saw blade. Then the slider is pushed again to approach the grinding disc to grind another tooth. This reciprocating process is repeated until all the teeth on the saw blade are ground and the grinding of the saw blade is completed.

[0004] However, in the prior art, when grinding the saw blade, it is necessary to continuously push the slider to reciprocate along the slide rail. During the movement, the slider and the slide rail are constantly rubbing against each other, and lubricating oil needs to be applied between the slider and the slide rail to reduce the friction. In the past, when lubricating oil was applied to the slider and the slide rail, the lubricating oil needed to be found or purchased separately, which was very troublesome and affected the use efficiency of the grinding device.
