Embodiment Construction

[0016] Such as figure 1 , figure 2 as well as image 3 Shown is an extension structure used for straightening the end of the rail in the extension process that can effectively improve the yield of the rail during the straightening process provided by the present invention. The extension structure includes a connection assembly 1 and an extension force member 2, and the extension force member 2 is connected to the end 4 of the rail 3 through the connection assembly 1; during the straightening process of the rail 3, the The stress point 5 of the end portion 4 repeatedly bent by a roller straightener is located on the extension stress member 2 . In this application, by setting up a set of extension structure including connection assembly 1 and extension force member 2, and then connecting the extension structure with the end 4 of the rail 3 to be straightened through the connection hole 6 arranged at the end of the rail, the The stress point 5 of the end portion 4 of the rail...

Abstract

The invention discloses an extension structure, particularly discloses an extension structure for an extension process straightening steel rail end, and belongs to the technical field of design and manufacturing of roller production technology equipment. The extension structure which can effectively improve the steel rail yield and is used for the extension process straightening steel rail end in the straightening process is provided. The extension structure comprises a connecting assembly and an extension exerting part. The extension exertion part is connected to the steel rail end through the connecting assembly; and in the straightening process of the steel rail, the steel rail end is located on the extension exerting part through a repeatedly-bent exertion point of the roller straightening machine.

Description

technical field [0001] The invention relates to an epitaxial structure, in particular to an epitaxial structure used for straightening the end of a steel rail in the epitaxial process, and belongs to the technical field of design and manufacture of roll production process equipment. Background technique [0002] At present, when the vertical bending of heavy-duty steel rails is straightened by roller straightening machines, since the roller straightening machines use multiple supporting rollers and multiple pressing rollers arranged in parallel to form alternating loads, the straightened steel rails will generate Repeated bending deformation to achieve the purpose of straightening. Like this, owing to the structural defect that straightening machine itself exists, often can make the two ends of steel rail appear large-scale can't straightening zone, promptly production site usually said straightening dead zone. The rails in the straightening blind zone cannot be straightene...
