Problems solved by technology

Not only is the labor intensity high, but the main problem is that there are many errors caused by manual writing and input. Roll processing errors often occur, and re-turning or even roll scrapping results in losses ranging from 100,000 to 1 million yuan.

Abstract

The invention discloses a simulation design method for rolling hole patterns of a steel rail, and belongs to the technical field of design and manufacturing of steel rail rolling equipment. The simulation design method for the rolling hole patterns of the steel rail, provided by the invention, is convenient to operate, high in automation degree and capable of improving the simulation analysis accuracy and avoiding errors. The method comprises the following steps: developing a set of simulation design software comprising a CAD (Computer Aided Design) hole pattern design module, a CAE (Computer Aided Education) hole pattern optimization module and a CAM (Computer Aided Manufacturing) hole pattern processing code generation module, and calling corresponding database information through the modules respectively; designing the rolling hole patterns of all rolling passes of the steel rail, dividing finite element grids for the rolling hole patterns with different specifications, establishing and correcting a related boundary condition model, and generating CAM codes of the rolling hole patterns of rollers corresponding to all the rolling passes. Due to the fact that the design and optimization of the rolling hole patterns of the steel rail and the generation of CAM processing codes are completed through the software respectively, the operation is simplified, the efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a simulation design method, in particular to a simulation design method for rail rolling passes, and belongs to the technical field of design and manufacture of rail rolling equipment. Background technique [0002] The design of the current rail rolling pass is carried out in the following steps: [0003] Step 1: Manually design the pass pattern, that is, use CAD software to directly give the CAD drawing of the rail rolling pass pattern manually. The pass pattern is the disassembled mold, and the rectangular billet is rolled into rails through different pass patterns. The current design method is to manually draw a sketch of the pass after determining the pass system, and then mark the design dimensions on the sketch. Calculation of key design parameters such as rate. Labor-intensive and time-consuming. [0004] The second step: pass design optimization, commonly known as CAE simulation optimization. The accuracy and quali...
