Abstract

The invention discloses a pneumatic constant-pressure control type derusting machine for steel rails. The derusting machine is characterized by comprising a base, a pneumatic pressure mechanism, a mobile mechanism and a derusting mechanism, wherein the mobile mechanism is arranged on the base, and the pneumatic pressure mechanism is arranged on the mobile mechanism and connected with the derusting mechanism. The derusting machine can derust tops and bottoms of the steel rails automatically before flash welding of the steel rails, and the flash welding effect is improved, so that the production efficiency of a whole steel rail production line is improved.

Description

technical field [0001] The invention relates to the field of derusting machines, in particular to a pneumatic constant pressure control type derusting machine for rails. Background technique [0002] Before flash contact welding of GAAS-80 rails, it is necessary to derust the rail top and rail bottom conductive clamping parts, otherwise it will directly affect the effect of welding production, thereby affecting the production efficiency of the entire rail production line . [0003] The commonly used derusting methods now generally include manual grinding with a manual grinding wheel or using a non-circular grinding head derusting machine for derusting. However, the manual grinding wheel grinding method has high labor intensity and low efficiency, and the technical requirements cannot meet the standards. The surface of the rail derusting is uneven, which affects the welding production effect. [0004] And the derusting machine of circular grinding head type is as disclosed ...
