Embodiment Construction
[0031] Such as figure 1 A method for forming a large space curved panel shown includes the following steps:
[0032] Step 1, drawing a structural diagram of a large space curved panel to be processed;
[0033] Step 2, dividing the structure diagram into a plurality of structure diagram units;
[0034] Step 3, select a plane plate according to the structure diagram, and divide the plane plate into a plurality of plane plate units, and a plurality of the plane plate units correspond to a plurality of the structure diagram units;
[0035] Step 4, cutting a plurality of said planar plate units from said planar plate in sequence;
[0036] Step 5, select a plurality of curved panel pressing molds, the curved panel pressing molds are used to press the flat panel unit into the corresponding actual shape of the structural drawing unit, a plurality of the curved panel pressing molds and a plurality of the structure Map unit one-to-one correspondence;
[0037] Step 6. Install the cur...

The invention discloses a forming method for a large space curved face plate. The forming method comprises the following steps that a structure chart of the large space curved face plate to be machined is drawn; the structure chart is divided into a plurality of structure chart units; a plane plate is selected according to the structure chart and divided into a plurality of plane plate units; the multiple plane plate units are cut down from the plane plate in sequence; a plurality of curved face plate pressing molds are selected; the curved face plate pressing molds are mounted on a press machine, one plane plate unit is pressed into one curved face plate unit through interaction of the press machine and the curved face plate pressing molds, and the multiple plane plate units are sequentially pressed into the multiple curved face plate units in this manner; and according to the structure chart, the multiple curved face plate units are subjected to butt welding and connected to form the large space curved face plate. According to the forming method, the large space curved face plate is manufactured through a segmentation butt welding manner, the problem that the requirements for the power and size of the press machine are high is effectively solved, and meanwhile cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of processing space curved surface plate parts, and in particular relates to a forming method of a large space curved plate. Background technique [0002] Usually, equal-thickness plate parts with spatial curved surface are manufactured by mold pressing and then peripheral processing and forming, that is, in the first step, the spatial curved surface is first expanded (the expansion of some curved surfaces is approximate), and the It becomes a plane with a certain shape and size; in the second step, according to the plane shape, a certain margin is placed around the periphery, and the flat plate is used for blanking; in the third step, the flat plate after the volume is pressed on a special mold ( The mold is installed on the press and can be heated appropriately); the fourth step is peripheral processing. This method is suitable for smaller parts of this type. Affected by the power of the press, if the as...
