Problems solved by technology
[0003] The invention aims at the low forming efficiency of the existing flanging forming technology, the quality stability and consistency of the flanging parts are difficult to guarantee, and the flanging part is prone to sag, so it can only be used for flanging with small arc radius and small arc opening angle In view of the lack of accurate forming of parts, a multi-pass robot flexible flanging full mold forming method is proposed, which can effectively improve the forming performance and forming quality of sheet metal flanging parts. The method is simple and feasible, and the production efficiency is high. It is used in aviation, aerospace, automobile Manufacturing and other engineering fields have important engineering application value and obvious economic benefits

Embodiment Construction
[0016] like figure 1 As shown, the present embodiment relates to a multi-pass robot flexible flanging full-mold forming device, including: a full-mold flanging worktable 1, a pressing module arranged thereon, and a roller 8 for forming, wherein: The sheet material 7 to be formed is placed under the pressing module on the full-die flanging table 1 .
[0017] The pressing module includes: a triangular spacer 2 and a straight-toothed pressing plate 6 respectively in contact with the side and top surfaces of the sheet material 7 to be formed, wherein: the straight-toothed pressing plate 6 is fixedly arranged on the full-mold turn through the screw 3 and the nut 4. side table 1.
[0018] The full-mold flanging workbench 1 is a workbench with an inclined surface, and the inclined surface and the plane part are smoothly transitioned through the transition fillet, and the transition fillet radius is set to 3mm; the inclined surface angle is the same as the flanging angle of the targe...

A multi-pass robot flexible flanging full-mold forming method. In the process planning stage, the lower plane of the sheet to be formed is used as the reference plane, the center of the sheet is the origin, a three-dimensional Cartesian coordinate system is established, and the roller is first set to move along the X-axis to Move the starting point, and then set multi-pass flanging forming around the Y-axis according to the flanging opening angle of the target flanging piece; The radius of the transition fillet, the length of the pressing part of the sheet to be formed, the length of the flanging part, the radius of the roller, the distance from the bottom of the roller to the theoretical tangent point when the roller and the sheet are formed; and the Y-axis coordinates of the die plane are calculated to obtain each pass The initial coordinates of the secondary rollers; in the execution stage, the industrial six-axis robot controls the rollers to reach the initial coordinates of the rollers for each pass and applies a forming force to the to-be-flanged part of the sheet to realize flexible flanging forming. The present invention can effectively improve sheet metal flanging. The forming performance of parts is improved and the forming quality is improved, and the method is simple and feasible.
Description
technical field [0001] The invention relates to a technology in the field of sheet metal parts manufacturing, in particular to a multi-pass robot flexible flanging full-mold forming method. Background technique [0002] Sheet metal flanging components have a wide range of applications in the aerospace field. However, due to the large variety and small batches, at present, most of these sheet metal flanging parts are formed by manual hammering, which is noisy, low in forming efficiency, and difficult to guarantee the quality stability and consistency of the flanging parts. As sheet metal flanging structural parts become more and more abundant and product development cycles are getting shorter and shorter, the existing manual hammer flanging forming process and manufacturing quality are difficult to meet the ever-changing product demands and the ever-accelerating production rhythm. Therefore, it is urgent to develop a new sheet metal flanging process to solve the current manu...
