Abstract

This utility model discloses a rotary saw blade with a carbide-tipped, indexable head. The saw teeth have slots with openings inclined towards the top surface of the teeth. The top surface of the teeth has countersunk holes, and the bottom surface of the slots has threaded holes. The blade head is shaped like an inverted isosceles trapezoid with curved sides, and a through hole on the top surface. Both ends of the blade head can be used. After one end wears down, the blade head can be rotated 180° for continued use, greatly improving the utilization rate of the blade head and reducing production costs.

Description

Technical Field

[0001] This utility model belongs to the field of saw blade technology, specifically, it relates to a rotary carbide circular saw blade with an indexable cassette cutter head. Background Technology

[0002] After prolonged use, the saw blade tip will wear down. Commonly used saw blades with welded tips cannot have their teeth replaced and must be scrapped. Saw blades with screw-fixed tips can have their tips replaced, but this still does not save costs. In order to further reduce production costs, a solution is needed to address this problem. Utility Model Content

[0003] In view of this, the technical problem to be solved by this utility model is to provide a rotary carbide-tipped circular saw blade, which solves the problem of high cost of saw blades in the prior art.

[0004] To solve the above-mentioned technical problems, this utility model discloses a rotary saw blade with a carbide cutter head, including a saw blade body; a mounting hole and saw teeth provided in the saw blade body; a cutter head provided in the saw teeth; and a screw; the saw teeth are provided with a groove, the groove opening is inclined towards the top surface of the saw teeth, the top surface of the saw teeth is provided with a countersunk hole, and the bottom surface of the groove is provided with a threaded hole; the cutter head is in the shape of an inverted isosceles trapezoid, and the two sides are arc surfaces, and the top surface of the cutter head is provided with a through hole.

[0005] Furthermore, the angle between the top surface of the slot and the top surface of the serration is 17°.

[0006] Furthermore, the width of the aforementioned blade head is greater than the width of the saw blade body, and the two sides of the blade head in the axial direction are beveled surfaces.

[0007] Furthermore, the aforementioned screw passes vertically through the cutter head to secure it to the saw teeth.

[0008] Compared with the prior art, this application can achieve the following technical effects:

[0009] The cutting head of this invention is made into an isosceles trapezoid shape with curved sides, so that both ends of the cutting head can be used. After one end of the cutting head is worn, the cutting head can be rotated 180° and continued to be used, which greatly improves the utilization rate of the cutting head and reduces production costs.

[0010] Of course, any product implementing this application does not necessarily need to achieve all of the technical effects described above at the same time. Attached Figure Description

[0011] The accompanying drawings, which are included to provide a further understanding of this application and form part of this application, illustrate exemplary embodiments of this application and are used to explain this application, but do not constitute an undue limitation of this application. In the drawings:

[0016] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0017] Please refer to Figure 1 , Figure 2 , Figure 1 This is a schematic diagram of a rotary saw blade with a carbide cutter head according to an embodiment of the present invention; Figure 2 This is a partial schematic diagram of a rotary saw blade with a carbide-coated, indexable head according to an embodiment of the present invention. A rotary saw blade with a carbide-coated, indexable head includes a saw blade body 1; the saw blade body 1 has mounting holes 2 and saw teeth 3; the saw teeth 3 have cutting heads 4; and screws 5; the saw teeth 3 have slots 6, the opening of which is inclined towards the top surface of the saw teeth 3, the top surface of the saw teeth 3 has countersunk holes 7, and the bottom surface of the slots 6 has threaded holes 8; the cutting heads 4 are in the shape of an inverted isosceles trapezoid, with curved surfaces 9 on both sides, and a through hole 10 on the top surface of the cutting heads 4.

[0018] The angle between the top surface of the slot 6 and the top surface of the saw tooth 3 is 17°. The cutter head 4 is set in the slot 6, and one end of the cutter head 4 is also biased upward. The slot 6 has a clamping force on the cutter head 4. The screw 5 passes vertically through the cutter head 4 and fixes it to the saw tooth 3, making the cutter head 4 more secure. The width of the cutter head 4 is greater than the width of the saw blade body 1, and the two sides of the cutter head 4 in the axial direction are inclined surfaces 11.

[0019] The cutting head 4 of this invention is made into an isosceles trapezoidal shape with two curved surfaces 9 on both sides. Both ends of the cutting head 4 can be used. After one end of the cutting head 4 is worn, the cutting head 4 can be rotated 180° and continued to be used, which greatly improves the utilization rate of the cutting head 4 and reduces production costs.

[0020] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
