Abstract

The invention discloses a steel-aluminum guide rail which comprises a movable bearing rail, two groups of slide rails and sliding auxiliary parts, wherein grooves are formed in the two sides of the movable bearing rail respectively; the two groups of slide rails are arranged in the grooves formed in the two sides of the movable bearing rail in a sliding mode through the sliding auxiliary parts respectively; a first wear resistant part is arranged between each sliding auxiliary part and each group of slide rails; a second wear resistant part is arranged between each sliding auxiliary part and the movable bearing rail; the movable bearing rail and the slide rails are all made of aluminum alloy; and the first wear resistant parts and the second wear resistant parts are all made of steel. The steel-aluminum guide rail can greatly promote the bearing capability of the guide rail and prolong the service life, has very excellent performance and is lower in cost compared with the traditional guide rail with the same bearing capability.

Description

technical field

[0001] The invention relates to a guide rail, in particular to a steel-aluminum guide rail. Background technique

[0002] A guide rail is a workpiece that enables objects to carry reciprocating telescopic movements on the guide rail. The existing industrial guide rails are generally three-section guide rails, including inner rails, middle rails and outer rails. And the compression caused by the inner rail makes the deformation of the three-section guide rail more serious after being fully stretched. In addition, the current guide rail is generally made of steel, because steel has high density, high hardness, and good tensile resistance, which can well meet industrial requirements. But on the other hand, due to the heavy weight of the steel itself, the overall weight of the steel guide rail is heavier, which further aggravates the deformation of the guide rail after it is fully stretched, so that the steel guide rail with a fully stretched length of 1200mm ca...
