Problems solved by technology

[0002] At present, when the sheet is formed, a rolling machine is used to form the sheet, but when the sheet is rolled, it is necessary to conduct a simulation study on the value of the roll forming. Currently, the simulation study is carried out on the roll forming value At that time, there was no complete set of research methods, and the research could only be carried out based on the work experience of the technicians, which could easily lead to deviations in the research direction and lead to research errors

Abstract

The invention provides a three-roller edge rolling shaping numerical modeling simulation study method. The study method includes steps of confirming geological dimension of a model roller and a belt steel according to the technical parameter of a plate bender; according to the stress condition in the shaping process, reducing the calculation time while selecting a two-dimensional plane model to model; selecting three shaping rollers as analysis rigid bodies, confirming analysis step and boundary condition; when every surface of the shaping roller, the steel plate and the pressing plate is defined and contacted, setting the requirement about main and slave contact faces in the process of releasing according to ABAQUS, setting the rigid surface as a main face and upper and lower surfaces ofthe steel plate as slave faces; setting the contact face between the pressing plate and the steel plate as the main face, upper and lower surfaces of the steel plate as the slave face; selecting the unit type and classifying the network; acquiring a simulation result and analyzing it. Every numerical value is simulated and analyzed when the panel is rolled to be circle, the circle rolling work canbe studied conveniently; the technical improvement can be carried out exactly and precisely in further study.

Description

technical field [0001] The invention relates to the field of plate forming, in particular to a numerical simulation research method for three-roll roll forming. Background technique [0002] At present, when the sheet is formed, a rolling machine is used to form the sheet, but when the sheet is rolled, it is necessary to conduct a simulation study on the value of the roll forming. Currently, the simulation study is carried out on the roll forming value At that time, there was no complete set of research methods, and the research could only be carried out based on the work experience of the technicians, which could easily lead to deviations in the research direction and lead to research errors. Therefore, it is particularly important to design a numerical simulation research method for three-roll roll forming. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a numerical simulation research met...
