Description

Alloy blade

Technical field

The utility model is related to a kind of alloy blades, are suitable for chain saw.

Background technology

In the industries such as forest lumbering, sawmilling, chain saw is widely used, and for chain saw, saw chain is that it must Indispensable accessory, and to for saw chain, blade is its primary clustering.

During lumbering, blade is in direct contact with trees, and in high temperature and high-frequency sawing process, blade is using After a period of time will rust when sawing high rigidity timber (especially, rust speed is exceedingly fast), cause Felling Efficiency to be lower.

When blade abrasion to a certain extent, then need to blade cutting edge carry out reconditioning after can be continuing with；When reconditioning to one Determine degree, then blade is scrapped, the saw chain that need to renew.

Invention content

The technical problems to be solved in the utility model is：In view of the above problems, a kind of simple in structure, making is provided Convenient, wear-resisting alloy blade reduces cost to prolong the service life.

Technical solution used by the utility model is：A kind of alloy blade, is made of blade base and cutter head, feature It is：The cutter head is divided into head body and the alloy head positioned at cutter edge, wherein head body and the blade base one System is at the alloy head is weldingly connected with head body and blade base.

The alloy head includes being linked to be " Ya " blade part and interconnecting piece of font, the wherein separate head body end of blade part It is close to the close alloy head end end face of head body and is weldingly connected in close head body end end face for cutting edge, blade part；Institute The close head body end end face for stating interconnecting piece is close to the close alloy head end end face of head body and is weldingly connected, under interconnecting piece It is close to the upper surface of the blade base and is weldingly connected in end face.

The close alloy head end end face of the head body and the upper surface for the blade base being connected with the interconnecting piece it Between angle be acute angle.

The utility model has the beneficial effects that：Blade of the utility model by using wear-resisting alloy head as blade, The abrasive resistance for improving blade reduces use cost, and the utility model is only set at cutting edge position to prolong the service life Alloy head is set, the usage amount of wear-resistant alloy material is less, and cost of manufacture is relatively low.Alloy head and head body in the utility model The font end faces " Ya " are in close contact and are weldingly connected, and alloy head lower face is weldingly connected with blade base, it is ensured that alloy head with The overall structure of head body and blade base is connected firmly.

Description of the drawings

Fig. 1 is the structural schematic diagram of embodiment.

Fig. 2 is the schematic diagram of head body and blade base in embodiment.

Fig. 3 is the structural schematic diagram of alloy head in embodiment.

Specific implementation mode

As shown in Figure 1, the present embodiment is a kind of alloy blade, including blade base 1 and cutter head 2, wherein cutter head 2 is by cutter head Main body 21 and positioned at cutter edge position alloy head 22 form.

As shown in Fig. 2, head body 21 is connected to 1 upper end of blade base, and head body and blade base one in this example System at.The 22 end end face Cheng " Ya of close alloy head of head body 21 " fonts, and between 1 upper surface of the end face and blade base Angle be acute angle.

Alloy head 22 is made of blade part 221 and interconnecting piece 222 in the present embodiment, and blade part and interconnecting piece are made into integration, And blade part and interconnecting piece are linked to be with the close alloy head end end face of head body to " Ya " font being adapted to, the blade part it is remote It is cutting edge from head body end (see Fig. 3).

In this example alloy head 22 be embedded in head body 21 close alloy head end end face and blade base 1 upper surface it Between, the close alloy head end end face of head body is close in the 21 end end face of close head body of blade part 221, and is weldingly connected； The close alloy head end end face of head body is close in the 21 end end face of close head body of interconnecting piece 222, and is weldingly connected；Connection The upper surface of the blade base is close in 222 lower face by portion, and is weldingly connected.

Certainly, above description is not limitation of the utility model, and the utility model is also not limited to the example above, this skill The those of ordinary skill in art field, in the scope of the utility model, variation, addition or the replacement made should all belong to this reality With novel protection domain.
