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-roll forming, in particular to an equipment and method for push-roll forming rails. Background technique [0002] Electric light rail vehicle is an environmentally friendly and efficient urban public transportation tool, which has attracted widespread attention at home and abroad and is increasingly popularized and applied. The track used has the function of vibration reduction and noise reduction. The existing way to manufacture this track is to use a large steel rolling mill to produce it with a large horizontal or tandem multi-roll mill or an extrusion method. The billet needs to be heated to the rolling state as a whole. After multi-pass rolling, heat treatment, straightening, finishing and other processes are required. After passing the inspection, it is a finished product. There are many processes from heating to finished products, and the investment and costs are relatively large, but i...
