Technical field
The present invention relates to the sanders of a kind of sander, specifically a kind of rail for polishing orbit.
Background technology
Sander for the rail of polishing orbit generally comprises braced frame, which is designed to roll by pattern Son rolls on rail, and has adjustable polishing unit, and braced frame is mounted to by pivot driver device in assembly fixture Upper pivot, assembly fixture have features designed to the guide roller rolled on rail, wherein, in both tracer roller and guide roller Each, which has, is arranged for the corresponding rolling surface rolled on rail head, also, be designed to be applied to the guiding of rail head Component is connected to assembly fixture in a manner of allowing to be separated by a distance relative to braced frame.The existing rail in polishing orbit The braced frame intensity of sander is relatively low.
Invention content
The technical problems to be solved by the invention are, for above shortcoming of the existing technology, to propose one kind for beating The sander of the rail of track is ground, braced frame has higher yield strength, tensile strength and elongation percentage, and with excellent Low-temperature flexibility.
The present invention solve more than technical problem technical solution be：
A kind of sander of rail for polishing orbit, including braced frame, the chemical composition of braced frame presses quality Percentage is：C：0.17-0.19%, Si：0.32-0.34%, Mn：1.82-1.84%, Ni：0.17-0.19%, Cr：0.35- 0.37%, Mo：0.21-0.23%, Nb：0.07-0.09%, Ti：0.023-0.025%, V：0.025-0.027%, P≤ 0.002%, S≤0.002%, B：The Fe and inevitable impurity of 0.007-0.009% and surplus.
The technical solution that further limits of the present invention is：
It is previously described for the sander of the rail of polishing orbit, the wherein chemical composition of braced frame by weight percent For：C：0.17%, Si：0.32%, Mn：1.82%, Ni：0.17%, Cr：0.35%, Mo：0.21%, Nb：0.07%, Ti： 0.023%, V：0.025%, P：0.002%, S：0.002%, B：0.007% and Fe and the inevitable impurity of surplus.
It is previously described for the sander of the rail of polishing orbit, the wherein chemical composition of braced frame by weight percent For：C：0.18%, Si：0.33%, Mn：1.83%, Ni：0.18%, Cr：0.36%, Mo：0.22%, Nb：0.08%, Ti： 0.024%, V：0.026%, P：0.001%, S：0.001%, B：0.008% and Fe and the inevitable impurity of surplus.
It is previously described for the sander of the rail of polishing orbit, the wherein chemical composition of braced frame by weight percent For：C：0.19%, Si：0.34%, Mn：1.84%, Ni：0.19%, Cr：0.37%, Mo：0.23%, Nb：0.09%, Ti： 0.025%, V：0.027%, P：0.001%, S：0.001%, B：0.009% and Fe and the inevitable impurity of surplus.
