Multi-pass robot flexible flanging full-die forming method

Abstract

A multi-pass robot flexible flanging full-die forming method comprises the steps that in the process planning stage, the lower plane of a to-be-formed plate serves as a datum plane, the circle center of the plate serves as an original point, a three-dimensional rectangular coordinate system is established, a roller is arranged to firstly move to a movement starting point along the X axis, and then multi-pass flanging forming is arranged around the Y axis according to the flanging opening angle of a target flanging piece; according to the inner diameter, the arc opening angle and the thickness of the original plate, the flanging opening angle and the transition fillet radius of the target flanging piece, the length of the pressed part of the to-be-formed plate, the length of the flanging part, the radius of the roller, the theoretical tangency point distance from the bottom surface of the roller to the forming of the roller and the plate, and the Y-axis coordinate of the die plane, the initial coordinate of each pass of roller is calculated; and in the execution stage, an industrial six-axis robot is used for controlling the roller to reach the initial coordinate of each pass of roller, and forming force is applied to the to-be-flanged part of the plate so as to achieve flexible flanging forming. The forming performance of the sheet metal flanged part can be effectively improved, the forming quality can be improved, and the multi-pass robot flexible flanging full-die forming method is simple and feasible.

Description

Technical field [0001] The present invention relates to a technique in the field of sheet metal parts, which is specifically a method of flexible flexible molding method for multi-channel robots. Background technique [0002] The sheet metal flanks have a wide range of applications in the aerospace field. However, due to the large variety, small volume, the current type of sheet metal is mostly used in artificial hammering, the noise, low forming efficiency, and the quality stability and consistency of the wound side are difficult to ensure it. As the sheet metal converting structure is getting stronger, the product development cycle is getting shorter, and the existing artificial hammering forming process and manufacturing quality is difficult to meet the changing product needs and the continuous accelerated production. Therefore, it is urgent to develop a new sheet metal flap process to solve the current manufacturing problem of the current sheet metal flange structure. Invent...
