Embodiment Construction

[0036] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0037] All the features disclosed in this specification, or all the steps in the methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any way. Unless specifically stated, they can be other equivalents or similar. The intended alternative features are replaced, that is, unless specifically stated, each feature is one embodiment in a series of equivalent or similar features.

[0038] Such as figure 1 As shown, the schematic diagram of the structure of the billet is formed after rolling as figure 2 The light rail car track.

[0039] This technology is a metal push rolling te...

Abstract

The invention discloses equipment and a method for pushing and rolling molding of a rail. The equipment comprises a thrust device 1, a heating device 2, roller devices 3, reshaping and straightening devices 4, a reheating device 5 and an atomizing and spraying device 6 which are arranged sequentially; and a guide component 7 is arranged on the equipment to guide movement of a steel blank 8. The metal pushing and rolling technology is as follows: at the state that metal reaches the rolling temperature through induction heating, the steel blank is pushed by the thrust device, is rolled, is subjected to reeling and is straightened by longitudinal columns of molds and is heated and subjected to spraying treatment to reach the light rail parameter requirements, the manner combines metal extrusion, rolling and online heat treatment, the investment is lower than that of a traditional manner, the production organization is flexible, the cost is relatively low, the technology is applicable to medium and small-sized enterprises, and other kinds of like profile steel can be produced with the rolling method and changed combination manners and structures of hole patterns.

Description

Technical field [0001] The invention relates to the technical field of metal push-rolling forming, in particular to an equipment and method for push-rolling forming rails. Background technique [0002] Electric light rail vehicles are an environmentally friendly and efficient urban public transportation tool, which has attracted widespread attention at home and abroad and has been increasingly popularized and applied. The track used has the function of vibration and noise reduction. The existing way to manufacture this track is to use large steel rolling mills, use large horizontal or vertical multi-roll rolling mills or extrusion methods, horizontal and vertical rolling mills The billet needs to be heated to the rolling state as a whole, and after multiple passes are rolled, multiple processes such as heat treatment, straightening, and finishing are required, and the finished product is qualified after inspection. There are many processes from heating to finished products, and ...
