Abstract
A method for cutting side plates and end plates of a scrapped railway boxcar aims to improve low disassembling efficiency as it is difficult to disassemble the scrapped railway boxcar. The steps of cutting the side plates includes: A1: cutting a top of an upper side plate; A2: performing cutting downwards, dividing the upper side plate, and then cutting the left upper side plate; A3: cutting the right upper side plate; A4: cutting a lower side plate; A5: cutting off upper channel steel on columns; A6: cutting off lower channel steel on the columns; and A7: cutting the columns. The method avoids complicated working conditions of directly cutting angle iron, the channel steel, multilayer boards and closed regions, so that the cutting efficiency of the side plates and the end plates of the boxcars is improved. Moreover, automatic cutting can be realized according to a set cutting path.
