AI Technical Summary
Existing saw blades suffer from chipping issues during the cutting process due to welding, resulting in high usage costs and the inability to reuse alloy blades.
The machine adopts a clamp-on structure, with the alloy blade connected to the lower end and the stepped platform and fixed with a safety bolt. This ensures that the alloy blade fits snugly against the saw blade body and breaks off automatically before the saw blade breaks, making it easy to disassemble and reuse the alloy blade.
It achieves the same cutting effect as welded saw blades while reducing usage costs. It can be used again by replacing the safety bolts, and the alloy blades are reusable.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of mechanically clamped carbide toothed circular saw blades, and in particular to a mechanically clamped carbide toothed circular saw blade. Background Technology
[0002] In heavy-duty cutting saw blades, alloy cutting tips are usually welded onto a high-speed steel substrate to form a saw blade. This reduces costs and increases cutting strength. However, during the cutting process, due to stress and high temperature, the saw blade may chip. Because of the welding, the saw blade cannot be used, and the remaining alloy cutting tips welded onto the saw blade also cannot be used, resulting in a relatively high cost of using the saw blade.
[0003] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content
[0004] A mechanically clamped carbide toothed circular saw blade includes a saw blade body, wherein the outer edge of the saw blade body is provided with a plurality of countersunk groove structures arranged in an equidistant array in a ring shape.
[0005] It also includes an alloy blade, the lower end of which is inserted into and fits against the countersunk structure. In addition, a coaxial fixing hole is provided between the saw blade body and the alloy blade. It also includes a safety bolt that is threaded to the saw blade body and passes through the fixing hole on the saw blade body and the alloy blade to fix the saw blade body and the alloy blade.
[0006] Preferably, the saw blade body is provided with a stepped platform and an insertion hole, wherein the lower end of the alloy blade is provided with a matching stepped surface that fits into the stepped platform, and the lower end of the alloy blade is also provided with a mounting flange that is inserted into the insertion hole.
[0007] Preferably, the saw blade body is provided with a threaded stepped hole, and the safety bolt is threadedly connected to the threaded stepped hole.
[0008] Preferably, the saw blade body is provided with a secondary pin hole, the secondary pin hole and the threaded stepped hole are coaxial and located on the other side of the saw blade body, and the mounting flange is provided with a mounting insertion hole.
[0009] Preferably, the safety bolt consists of a pin sub-section, a pin main section, a safety cut-off section, and an internal hexagonal thread end, from beginning to end, wherein the pin sub-section is inserted into the pin hole and the pin main section is inserted into the mounting hole.
[0010] Preferably, the diameters of the safety cutting section and the pin sub-section are both smaller than the diameter of the pin main section, and the material strength of the safety cutting section and the pin sub-section is less than the material strength of the saw blade body.
[0011] The advantages and positive effects of this utility model are:
[0012] The saw blade employs a mechanical clamping mechanism. The alloy blade effectively bears force through the connection between its lower end, the stepped platform, and the mounting flange inserted into the socket. During cutting, the safety bolt ensures that the alloy blade is completely in contact with the saw blade body, achieving a cutting effect consistent with welding. Furthermore, due to the structure and strength design of the safety cutting section and the pin sub-section, it can self-break before the saw blade breaks. Thus, it can continue to be used by replacing the safety bolt. Even if the saw blade body is also damaged and cannot be used, the alloy blade corresponding to the remaining good position of the safety bolt can be disassembled and reused, effectively reducing the cost of use.
