Title:
CHAIN SAW GUIDE PLATE
Document Type and Number:
WIPO Patent Application WO/2009/030089
Kind Code:
A1
Abstract:
A chain saw guide plate includes a rectangular metal plate which is consisted
of a body of chain saw guide plate shape and a removable part extending around said
body, both surfaces revealed in the front end of body extend to a boundary between
the removable part and the body, and each of arc channels is provided respectively
on the both surfaces revealed in the front end of body, the bowed parts of said arc
channels are frontward, a weld powder is molten and solidified in the channels
to form powder structures, thus the top surface and the bottom surface of metal
plate form a flat surface respectively, then the removable part is separated
from the body so that said powder structures are revealed, a guide channel is provided
toward inside of body between both powder structures. Thus the invention uses
a powder structure of lower price, and first the powder structure is molten in
the places which bear high temperature and high abrasion, then to form a guide
plate of chain saw by general machining, the invention is convenient for machining
of required shape, and can avoid waste for material.
