[0025] Working principle of this utility model:

[0026] like Figure 1 As shown, during use, the expansion mold requires the expansion guide sleeve 114 and expansion guide post 115 to be aligned and connected to achieve overall docking stability. The expansion push rod 116 pushes the expansion lower template 102 to its moving position. The expansion bottom buffer spring 104 and the expansion ejector plate 105 cooperate to buffer the movement. The expansion polyurethane adhesive 107 and the expansion arc plate 108 shape the arc surface of the inner wall of the first workpiece 200, and the expansion lower cavity 106 shapes the arc surface of the outer wall of the first workpiece 200. The expansion push rod 116 and the expansion pressure block 117 complete the buffering between the expansion upper template 110 and the expansion upper cavity 113. Figure 2 As shown, the cutting edge ejector plate 309 at the bottom of the upper cutting edge template 304 presses down to cut off the corner of the second workpiece 201, thus facilitating subsequent processing. The cutting edge guide post 303 and the cutting edge guide sleeve 307 ensure the stable connection between the lower cutting edge template 300 and the upper cutting edge template 304. The cutting edge connecting bolt 306 connects the upper cutting edge template 304 and the cutting edge polyurethane adhesive 308. The cutting edge die 310 reinforces the cutting edge ejector plate 309 on the side. Figure 3As shown, the third workpiece 202 is fixed on the pre-bending lower template 400 using pre-bending polyurethane adhesive 401 and pre-bending guide post 402. Then, the pre-bending upper die 407 on the bottom side of the pre-bending upper template 405 presses down to cooperate with the pre-bending lower die 403 to achieve pre-bending of the corners of the third workpiece 202. The pre-bending base plate 404 and the pre-bending guide sleeve 406 cooperate to achieve the effect of stabilizing the pre-bending upper template 405. The pre-bending connecting bolt 408 connects the pre-bending upper template 405 and the pre-bending upper die 407. Figure 4 As shown, the edge-rolling plate 503 on the edge-rolling mounting column 502 is used to shape the corners of the fourth workpiece 203 mounted on the edge-rolling lower template 500, thereby achieving edge-rolling of the corners of the fourth workpiece 203. Figure 5 As shown, the flattening upper template 603, along with the flattening upper die 605, clamps the flattening lower die 601, flattening the bent corners of the fifth workpiece 204 to achieve workpiece processing. The flattening guide post 602 and the flattening guide sleeve 604 ensure the stability of the connection between the flattening lower template 600 and the flattening upper template 603. Figure 6 As shown, this illustrates the sequential processing configurations of the workpiece.
