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

[0003] Circular saw blades tend to generate a lot of debris during the cutting process. The large amount of debris flying in the air affects subsequent processing, and it is also easy to cause cleaning trouble after the cutting is completed. In the past, circular saw blades could only cut or grooved, and their functions were relatively simple. Utility Model Content

[0004] To address the technical deficiencies in the background technology, this utility model proposes an integrated circular saw blade for cutting and grinding, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0005] A circular saw blade integrating cutting and grinding includes: a saw blade body, a storage groove, cutting teeth, a grinding disc, and a mounting hole. The saw blade body has a storage groove on one side, which is the front side. A plurality of cutting teeth are arranged along the edge of the storage groove, evenly spaced and protruding outwards. Each pair of cutting teeth forms a slot, with its front and rear openings connecting to the outside and the inside of the storage groove, respectively.

[0018] 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.

[0019] like Figures 1 to 4As shown, a circular saw blade integrating cutting and grinding includes: a saw blade body 1, a storage groove 2, cutting teeth 3, a grinding disc 4, and a mounting hole 5. The saw blade body 1 has a storage groove 2 on one side, which is the front side. Several cutting teeth 3 are arranged along the edge of the storage groove 2, and they are all arranged in a sequentially equal manner along one edge of the storage groove 2 and protrude outwards. Each pair of cutting teeth 3 is combined to form a slot, and the front and rear openings of the slot are connected to the outside and the inside of the storage groove 2, respectively. An annular groove is opened on the back side of the saw blade body 1, and a grinding disc 4 is embedded in the annular groove of the saw blade body 1. A mounting hole 5 is opened at the center of the saw blade body 1.

[0020] After the present invention is installed on the corresponding driving device, the driving device drives the present invention to rotate. In the rotating state, the present invention cuts the workpiece. When the cutting tooth 3 of the present invention contacts the surface of the workpiece, the cutting debris is scraped into the collection groove 2 by the cutting tooth 3, so as to collect and concentrate the debris, avoid it from splashing outward, and also reduce the blockage of the cutting groove by the cutting debris. After the cutting is completed, the reverse side of the present invention can be attached to the cut edge of the workpiece, and the grinding disc 4 set on the reverse side of the saw blade body 1 can be used to repair the burrs or uneven areas on the surface of the cut edge of the workpiece.

[0021] With the above structure, it should be further explained that the storage groove 2 on the front of this utility model is used to collect the debris after cutting. When each cutting tooth 3 scrapes and cuts the surface of the workpiece, the hook-shaped cutting tooth 3 will bring the scraped debris into the groove between every two cutting teeth 3 during the cutting process, and fall into the storage groove 2 through the groove. In addition, during the cutting process of the saw blade body 1, both the front and back sides of the saw blade body 1 will be in close contact with the cutting groove. Therefore, during the cutting process, the debris will be collected in the storage groove 2, avoiding falling or clogging the cutting groove and causing cutting obstruction.

[0022] Each cutting tooth 3 is grooved to one side of the saw blade body 1, and the edge of the saw blade body 1 is embedded in the groove of each cutting tooth 3 and is fixedly connected.

[0023] The storage groove 2 on the front of the saw blade body 1 is composed of several cutting teeth 3 combined with the saw blade body 1.

[0024] With the above structure, it should be further explained that each cutting tooth 3 is connected to the saw blade body 1 by welding. The weld can be melted by hot melting to replace the damaged cutting tooth 3.

[0025] Each cutting tooth 3 is connected to the saw blade body 1 by screw engagement, which facilitates the replacement of each cutting tooth 3 and reduces the replacement process.

[0026] The depth of the annular groove on the reverse side of the saw blade body 1 is no more than two millimeters; the thickness of the grinding disc 4 is no more than one millimeter; the grinding disc 4 is glued and fixed in the annular groove.

[0027] With the above structure, it should be further explained that the depth of the annular groove is used to prevent the grinding disc 4 from falling out. If the depth is greater than two millimeters, it will easily lead to a decrease in the hardness of the saw blade body 1 itself. If the depth is less than two millimeters, it will easily lead to insufficient filling space for the grinding disc 4, making the grinding disc 4 easy to fall out of the annular groove.

[0028] The grinding disc 4 is fixed by adhesive, which makes it easy to replace and avoids the need to replace it with another saw blade after the surface of the grinding disc is worn down.

[0029] A ring is provided at each end of the mounting hole 5 and extends outwards to both sides of the saw blade body 1; the ring on the front of the saw blade body 1 does not extend beyond the side of the cutting teeth 3 corresponding to the saw blade body 1; a limiting groove 51 is provided inside the mounting hole 5 and the limiting groove 51 is arranged around the inner side of the mounting hole 5.

[0030] With the above structure, it should be further explained that the rings at both ends of the mounting hole 5 are used to provide positioning for external installation equipment. In order to ensure that the external installation equipment is fixed to this utility model, a recessed limiting groove 51 is also provided in the mounting hole 5 to provide a locking position for the external installation equipment and prevent the saw blade body 1 from falling off the external installation equipment after this utility model is installed.

[0031] The depth of the storage groove 2 is no greater than the depth of the annular groove.

[0032] After adopting the above structure, it should be further explained that the annular groove of this utility model is used to provide for the embedding of the grinding disc 4. Therefore, the annular groove cannot be too deep, and the embedded grinding disc 4 does not exceed the depth of the annular groove, so as to avoid the cutting obstruction caused by the protrusion of the grinding disc 4 during the cutting process of the saw blade body 1.

[0033] There is at least one limiting groove, which is recessed inward toward the mounting hole.

[0034] With the above structure, it should be further explained that when the limiting groove is used to provide external installation equipment for fixing this utility model, the positioning and fixing are achieved by the protrusion being embedded in the limiting groove.

[0035] 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.
