In some embodiments, four corners of the formed square skirt board are arc-shaped structures; or, four corners of the formed square skirtboard are of a right-angle structure. Therefore, the requirements of different apron board forming can be met.

In some embodiments, when the bracing structure is used for bracing the circular skirt panel, the center of the bracing structure coincides with the center of the circular skirt panel. Therefore, when the support rod moves along the radial direction of the circular apron board from the circle center of the circular apron board to support the circular apron board, the stress can be uniform, and the forming success rate of the apron board is high.

In some embodiments, the struts are equidistant from each other and are equidistant from the center of the distracting structure. Therefore, the skirtboard can be stretched by force when being stretched, so that the skirtboard is not stressed unevenly when being stretched, and the finished product of the skirtboard is inconsistent after being molded.

In some embodiments, the angle between the center of the distraction structure and the connecting line of two adjacent struts is 90 degrees. Therefore, the apron board can be expanded by the round apron board to form the square apron board.

In some embodiments, the circular apron board forming assembly comprises a flattening mechanism, a cutting mechanism, a rolling mechanism and a rib pressing mechanism which are arranged in sequence;

the method for forming the circular skirting board by the skirting board comprises the following steps:

flattening, namely flattening the skirt board raw material by a flattening mechanism;

cutting, namely leading the flattened apron board into a cutting mechanism, and cutting the apron board into apron board short boards with specified lengths by the cutting mechanism;

the short apron plate is led into a rolling mechanism, the short apron plate is rolled into a circle through the rolling mechanism, and then the short apron plate rolled into the circle is welded and fixed;

and (5) beading, namely introducing the skirt board fixed by welding into a beading mechanism, and beading the outer circumferential surface of the skirt board by using the beading mechanism. Therefore, the apron board can be rolled and welded, and the apron board is more stable after rolling and welding.

In some embodiments, the rolling mechanism comprises a rolling device, a clamping device and a push plate device; the method for carrying out the rolling and welding by the rolling mechanism comprises the following steps:

rolling, namely introducing the cut apron board short plate into a rolling device, and rolling the apron board short plate into a circle through the rolling device;

clamping and fixing, namely stretching the skirt board after the edge rolling of the edge rolling device onto the clamping device, and clamping the edge rolling skirt board through the clamping device, so that the roundness of the edge rolling skirt board is higher, and the stability of the roundness of the skirt board is better;

welding, push pedal device set up welded structure and stretch to clamping device on, weld the skirtboard that clamping device presss from both sides tightly, make the skirtboard after the edge rolling can be fixed. From this, through setting up clamping device and push pedal device, can make the skirtboard after the edge rolling fixed and welding, process automation need not manual operation and can realize edge rolling, fixed and welding process, and the skirtboard that the circularity of the skirtboard after the clamping device processing is higher, the better stability of the circularity of skirtboard.

In some embodiments, the flattening mechanism is provided with a differential roller group including a first roller and a second roller having different diameters, an axial direction of the first roller and an axial direction of the second roller are parallel, and the first roller and the second roller rotate in opposite directions in synchronization, and the apron board can pass between the first roller and the second roller. Therefore, through the arrangement of the differential roller group, the apron board rotates at the same rotating speed through the first rolling roller and the second rolling roller with different diameters, when the apron board is pressed on the first rolling roller and the second rolling roller, paths of the apron board between the first rolling roller and the second rolling roller with different diameters are different, and therefore pulling force can be generated between the first rolling roller and the second rolling roller, and the apron board is pressed flatly and more smoothly.

In some embodiments, the beading mechanism comprises a beading assembly, the beading assembly comprises an upper pressing wheel and a lower pressing wheel which are axially parallel and can rotate relatively on the outer peripheral surfaces, one of the upper pressing wheel and the lower pressing wheel is provided with an annular beading, the other one of the upper pressing wheel and the lower pressing wheel is provided with an annular groove, the annular groove and the annular beading can be matched with each other for the skirting board beading, and the upper pressing wheel and the lower pressing wheel can be relatively close to or far away from each other. From this, go up pinch roller and push down the wheel and can rotate in step, it is inhomogeneous to appear the beading when reducing skirtboard beading, and can relative movement between going up pinch roller and the push down wheel, and the opening degree is bigger.
