Embodiment Construction

[0034] The circular saw blade described in the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] The following are the best examples of the circular saw blades described in the utility model, which do not limit the scope of protection of the utility model.

[0036] Miter saw equipment that uses traditional methods includes:

[0037] Disc saw blade;

[0038] Multiple teeth are embedded around the saw blade, and each tooth creates a chip in the material being machined.

[0039] Chip evacuation notches are left on each tooth edge around the blade, and each tooth is firmly welded to the base.

[0040] The main feature of the device is that, for at least one tooth, the volume of chips discharged by the above-mentioned notches is smaller than the volume of chips produced by one tooth.

[0041] The above-mentioned state-of-the-art advocates removing the notches for chip discharge to reduce noise, while the...

Abstract

The circular saw blade includes a blade body having the form of a disc, and a plurality n (n>1) of teeth inserted into the peripheral rim of the blade body so as to be distributed over the circumference of the disc. Each tooth generates a chip derived from the machined material. There is a cut-out for the clearance of the chip being provided in the peripheral rim of the blade body at the level of each tooth, and incorporating a base seat to which the tooth is soldered. For at least one tooth, the cut-out defines a volume for clearance of the chip which is less than the apparent volume of the chip generated by a tooth.

Description

technical field [0001] The invention relates to cutting saw equipment for materials such as wood, metal or plastic. The chop saw apparatus includes at least one circular saw blade. The saw blade is characterized by less noise than conventional circular saw blades. Background technique [0002] In fact, whether it is a stationary machine (table saw or cross-cut saw) or a portable machine, whether idling or cutting, traditional saw blades can create a deafening noise as they spin. The noise can reach 90 to 100 decibels, causing discomfort to workers operating the machine or people nearby. Before issuing new regulations, manufacturers should prioritize efforts to reduce noise. [0003] The noise is mainly caused by the air flowing in the hollow space in front of the teeth of the saw blade. Air rushes between the teeth and the blade makes an unpleasant noise as it spins. Worse, the blade itself can also resonate and become a source of noise. [0004] In order to reduce the...
