Description

Technical Field

[0001] This utility model relates to a circular saw blade, and more particularly to a circular saw blade with grooves that facilitates the removal of debris. Background Technology

[0002] Circular saw blades are a common sawing tool, widely used for cutting materials such as metal, wood, and plastic;

[0003] During the cutting process, the circular saw blade generates a large amount of debris. Most of the debris is carried outward by the teeth of the circular saw blade. During the cutting process, some of the debris will fill the cutting groove, causing the circular saw blade to jam and making it difficult for the circular saw blade to continue the cutting process.

[0004] Furthermore, the cutting process easily generates a certain amount of heat, which accumulates in the cutting groove and circular saw blade. This heat can cause plastic products to melt, thus creating greater obstacles to cutting. In addition, when cutting metal or wood, the heat can easily cause deformation. Utility Model Content

[0005] To address the technical deficiencies in the prior art, this utility model proposes a circular saw blade with grooves that facilitates chip removal, thus solving the aforementioned technical problems and meeting practical needs. The specific technical solution is as follows:

[0006] A circular saw blade with grooves for easy debris removal includes: a circular saw body, grooves, blade holders, a discharge groove, and a fixing plate. The circular saw body has several grooves on its outward-facing sides. One end of each groove passes through the outer edge of the circular saw body, and the other end extends to the center of the circular saw body. The grooves are radially and evenly distributed on both sides of the circular saw body. Several blade holders are provided along the edge of the circular saw body and are welded to each other. The outward-facing edge of each blade holder is inclined in one direction, and a cutting head is fixed to the inclined surface of each blade holder. A mounting hole is formed at the center of the circular saw body, which is then inserted into an external drive device.

[0007] The fixing plate is provided in two pieces, and the two fixing plates are respectively fixed to the two side surfaces of the circular saw body, and the two are respectively attached to the circular saw body.

[0008] The thickness of the circular saw body is less than the thickness of the blade holder;

[0009] The grooves on the upper and lower sides are respectively positioned one above the other, and the thickness between the bottoms of the two grooves is not less than three millimeters.

[0010] The outward end of each groove extends between each two blade holders; the bottom of each groove is arc-shaped; the end of each groove facing the mounting hole is smaller than the outwardly extending end, and the end of each groove facing the mounting hole is in close contact with each corresponding fixing plate.

[0011] The circular saw body has several drainage grooves evenly distributed along its edge.

[0012] The opening of each of the drainage grooves faces the edge of the circular saw body, and the end of each drainage groove facing the mounting hole is circular.

[0013] The beneficial effects of this utility model are as follows:

[0014] After this invention is installed on a corresponding drive device, the device drives the circular saw to rotate, and several blades embedded in the circular saw body cut the surface of the object as the circular saw body rotates. After the blades cut the object, the resulting debris is scraped into the groove between the blades. Finally, by collecting the debris into the groove, the debris produced by this invention is prevented from filling the cutting gap during the cutting process, thus maintaining the smoothness of the cutting groove and preventing debris from flying outward. At the same time, when cutting plastic, it also prevents the heat generated during cutting from melting the plastic debris and causing the circular saw blade to stick together.

[0019] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0020] like Figures 1-4As shown, a circular saw blade with grooves for easy chip removal includes: a circular saw body 1, grooves 2, blade holders 3, a discharge groove 4, and a fixing plate 5. Several grooves 2 are formed on the outward-facing sides of the circular saw body 1. One end of each groove 2 passes through the outer edge of the circular saw body 1, and the other end extends to the center of the circular saw body 1. The grooves 2 are radially and evenly distributed on both sides of the circular saw body 1. Several blade holders 3 are provided along the edge of the circular saw body 1 and are fixed by welding. The outward-facing edge of each blade holder 3 is inclined in one direction, and a cutting head 31 is fixed to the inclined surface of each blade holder 3. A mounting hole 6 is formed at the center of the circular saw body 1 and is embedded in an external drive device. Two fixing plates 5 are provided, and the two fixing plates 5 are respectively fixed to the two sides of the circular saw body 1.

[0021] After the present invention is installed in the corresponding drive device, the device drives the rotation, and several blades 31 embedded in the circular saw body 1 cut the surface of the object as the circular saw body 1 rotates. After the blades 31 cut the object, the resulting debris is scraped into the groove 2 between the blades 31. Finally, by collecting the debris in the groove 2, the debris produced by the present invention is prevented from filling the cutting gap during the cutting process, keeping the cutting groove smooth, and also preventing the debris from flying outward. At the same time, during the cutting of plastic, it can also prevent the heat generated by the cutting from melting the plastic debris and causing the circular saw blade to stick together.

[0022] The thickness of the circular saw body 1 is less than the thickness of the blade holder 3; the upper and lower grooves 2 are respectively opposite each other, and the thickness between the bottom of the two grooves is not less than three millimeters.

[0023] With the above structure, it should be further explained that the thickness of the blade holder 3 is greater than that of the circular saw body 1, which can prevent the circular saw body 1 from being rubbed by both sides of the object during the cutting process, so that the cutting process is limited to the blade holder 3 driving the cutter head 31 to cut the object.

[0024] The grooves 2 are positioned opposite each other to avoid uneven chip filling in each groove 2, which would cause the resulting extrusion force to deform the circular saw body 1.

[0025] If the thickness between the bottoms of the two grooves is greater than three millimeters, the circular saw blade will be too thick, resulting in an excessively large groove and increased wear and tear on the object. If the thickness between the bottoms of the two grooves is less than three millimeters, the circular saw blade will be unable to cut.

[0026] The outward end of each groove 2 extends between each pair of blade holders 3; the bottom of each groove 2 is arc-shaped; the end of each groove 2 facing the mounting hole 6 is smaller than the outward-extending end, and the end of each groove 2 facing the mounting hole 6 is in close contact with each corresponding fixing plate 5.

[0027] After adopting the above structure, it should be further explained that the groove 2 becomes wider and narrower, inevitably resulting in an excessively large groove, which makes the present invention prone to deformation under pressure during the cutting process.

[0028] The mounting hole 6 of this utility model is provided with a fitting groove on the inner side to fit externally installed equipment.

[0029] Several drainage grooves 4 are provided on the edge of the circular saw body 1 and are evenly distributed; the opening of each drainage groove 4 faces the edge of the circular saw body 1, and the end of each drainage groove 4 facing the mounting hole 6 is arranged in a circle.

[0030] With the above structure, it should be further explained that the discharge groove 4 is used to provide debris adhering to the bottom of the cutting groove, which can further clean the debris.

[0031] Two fixing plates 5 are respectively attached to the upper part of the corresponding groove 2 and connected by welding.

[0032] With the above structure, it should be further explained that the fixing plate 5 is used to clamp several grooves 2 to avoid vibration during cutting and deformation of this utility model due to shaking.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
