Description

Technical Field

[0001] This utility model relates to the field of chainsaw blade technology, specifically to a high-strength cemented carbide chainsaw blade. Background Technology

[0002] A chainsaw is a power saw used for logging and timber processing. Its sawing mechanism consists of a chain of individual chainsaw blades and a chain shaft, hence the name.

[0003] Currently, in related technologies, chainsaw blades are usually made by welding the blade head to the base. However, the welding area between the blade head and the base of existing chainsaw blades is relatively small. This leads to the problem of the blade head and base disintegrating during heavy-duty use due to the low welding strength caused by the small welding area. This not only makes the chainsaw blade easy to damage, but also causes flying injuries to the user or people around when it disintegrates.

[0004] Therefore, the applicant has made beneficial designs and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Utility Model Content

[0005] The present invention provides a high-strength cemented carbide chainsaw blade to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-strength carbide chainsaw blade includes a base and a blade head. The base includes a connecting plate, and a first welding portion is provided on one side of the connecting plate. An insert block is provided on the top wall of the first welding portion. The blade head includes a cutting edge and a second welding portion is provided at the bottom of the cutting edge. An insert groove is formed on the bottom wall of the second welding portion. The top wall of the first welding portion and the bottom wall of the second welding portion are fitted together. The insert block is embedded in the insert groove, and the outer wall of the insert block is fitted together with the inner wall of the insert groove.

[0008] Preferably, the top wall of the first welded part and the bottom wall of the second welded part are both flat surfaces.

[0009] Preferably, the blade portion has a right-angled sharp structure.

[0010] Preferably, the cutter head is integrally forged from tungsten steel.

[0011] Preferably, the surface of the connecting plate has two connecting holes.

[0012] Beneficial effects

[0013] The high-strength cemented carbide chainsaw blade provided in this embodiment of the present invention has at least one of the following technical effects:

[0014] This utility model, through the above-mentioned technical solution, provides an interlocking block on the base and an interlocking groove on the blade head, with the interlocking block being fitted into the interlocking groove. This effectively increases the welding area between the base and the blade head, and improves the welding strength between the base and the blade head. This avoids the problem of the blade head and base head disintegrating due to insufficient welding strength caused by an insufficient welding area during heavy-duty use, thus improving the service life of the chainsaw and ensuring the safety of the user and surrounding personnel.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1-2 The diagram shown is a structural schematic of a high-strength cemented carbide chainsaw blade according to a preferred embodiment of the present invention.

[0023] In this embodiment, the device includes a base 100 and a cutting head 200. The base 100 includes a connecting plate 101. A first welding part 102 is integrally provided on one side of the connecting plate 101. An interlocking block 103 is integrally provided on the top wall of the first welding part 102. The cutting head 200 includes a cutting edge 201. A second welding part 202 is integrally provided at the bottom of the cutting edge 201. An interlocking groove 203 is formed on the bottom wall of the second welding part 202. The top wall of the first welding part 102 is in contact with the bottom wall of the second welding part 202. The interlocking block 103 is embedded in the interlocking groove 203. The outer wall of the interlocking block 103 is in contact with the inner wall of the interlocking groove 203. This effectively increases the welding area between the base 100 and the blade 200, improving the welding strength between them. This avoids the problem of the blade breaking apart between the blade 200 and the base 100 due to insufficient welding strength caused by an insufficient welding area during heavy-duty use, thus improving the service life of the chainsaw and ensuring the safety of the user and surrounding personnel. Furthermore, the interlocking block 103 and the interlocking groove 203 work together to precisely position the weld between the base 100 and the blade 200.

[0024] In this embodiment, the top wall of the first welding part 102 and the bottom wall of the second welding part 202 are both flat surfaces, so that the surfaces of the first welding part 102 and the second welding part 202 can fit perfectly together, reduce gaps, and further improve welding strength.

[0025] In this embodiment, the blade portion 201 has a right-angled sharp structure, which improves the sharpness of the blade portion 201 and reduces the power load on the blade head 200.

[0026] In this embodiment, the cutter head 200 is integrally forged from tungsten steel, which improves the overall hardness and strength of the cutter head 200.

[0027] In this embodiment, two connection holes 104 are provided on the surface of the connecting plate 101, through which adjacent chainsaw blades can be connected via a chain shaft.

[0028] The high-strength carbide chainsaw blade of this utility model can be installed, connected, or set in a common mechanical manner, and can be implemented as long as it can achieve its beneficial effect.

[0029] All technologies not described in detail in this utility model are known technologies. Those skilled in the art can easily implement this utility model based on their understanding of this specification, and the contents shown in the accompanying drawings are part of this specification.

[0030] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
