Specific embodiment

The utility model is further described with specific embodiment with reference to the accompanying drawing:

Referring to shown in Fig. 1 to Fig. 6, a kind of chain saw guide plate, including two pieces of outside plates 1 disposed in parallel, including two pieces set in parallel The outside plate 1 set, one end edge of the outside plate 1 are provided with wear ring 3, and the hardness of wear ring 3 is not less than the hardness of outside plate 1.

Be further arranged to: the width H of the wear ring 3 is less than 2 millimeters.

Be further arranged to: the Rockwell hardness of the wear ring 3 is 58-65 degree；In the present embodiment, the Rockwell of wear ring 3 Hardness is preferably 60 degree, and the Rockwell hardness of outside plate 1 is 20 degree, and the Rockwell hardness of wear is 53 degree.

Be further arranged to: the wear ring 3 is iron alloy clading, and the wear ring 3 is primary by arc welding and outside plate 1 Molding, increases wearability by the setting of wear ring 3, chain is made to be not easy to cause to wear to guide plate in rotation process on guide plate And guide plate will not be deformed due to fever, increase the service life of product；Iron alloy clading wear-resisting property is good, indeformable, resistance to punching It hits, it is anti-oxidant, it is only necessary to which that a small amount of alloy amount can surmount the alloy guide plate on existing market, replace present city with wear ring 3 Gear on field, and using effect is better than gear, long service life is able to achieve good and cheap.

It is further arranged to: being provided with several grooves 11 on the surface of the outside plate 1.
