Method for designing loading track for multi-pass roll bending of wall plate and generating numerical control code

Abstract

The invention discloses a method for designing a loading track for multi-pass roll bending of a wall plate and generating a numerical control code. The method is a parameterized design method for the loading track based on a Jammes 10008 tri-axial numerical control roll bending machine. The pressing volume of an upper roller at a section is calculated according to a forming curvature to solve at the extension of the driving mechanisms, and a corresponding numerical control code is obtained by referring to nominal data. According to the parameterized design method, a basic interface can be supplied to the optimization of the loading track, the demand on a parameter optimizing design for a roll bending technique of the wall plate is met, and the efficiency of optimizing design for the loading track is promoted. Compared with the traditional method for roughly confirming a technical process and parameters based on experience analysis and repeated bending tests, the method provided by the invention has the advantages that initial technical parameters and the corresponding numerical control code are quickly obtained and the test efficiency and the quality of parts are promoted.

Description

technical field [0001] The invention relates to a method for designing a multi-pass roll bending loading track of a wall panel, in particular to a design method for a multi-pass roll bending loading track of a wall panel and a numerical control code generation method based on a Jammes10008 three-axis numerically controlled roll bender. Background technique [0002] Roll bending is a process method of turning around the forming method without a mold. During processing, the processed plate will produce a certain plastic bending deformation due to the pressure exerted by the upper roller. When the lower roller is driven to rotate, the engagement torque formed by the friction between the sheet and the shaft roller enables the sheet to be fed; when the sheet passes through the deformation zone below the upper roller in turn, the sheet also obtains a Plastic bending deformation of the full length; after unloading and springback, the working bending part finally obtains residual de...

Problems solved by technology

When the lower roller is driven to rotate, the engagement torque formed by the friction between the sheet and the shaft roller enables the sheet to be fed; when the sheet passes through the deformation zone below the upper roller in turn, the sheet also obtains a Plastic bending deformation of the full length; after unloading and springback, the working bending part finally obtains residual deformation of equal curvature. The process parameters such as the distance between the two lower rolls and the movement track of the upper roll are formed. The traditional wall plate roll forming method uses empirical analysis and repeated trial bending to roughly determine the process program and parameters, and manually adjusts the parameters and parameters of the control equipment. processing
