The working principle is as follows: the telescopic rod of the shaping cylinder of the shaping device of the bending and shaping device is retracted, and the shaping pressing plate is driven to be lifted to a state of waiting for pressing and shaping; the shaping conveying drive of the shaping conveying device of the bending forming device drives the shaping mould to rotate to the position, close to the short supporting leg of the bending forming frame, of the shaping mould to be just aligned with the pushing rod of the pushing device of the shearing pushing device of the drying shearing device of the preamble procedure, and the pi/2+/-pi/30 part, cut off by the wall of the shaping mould, of the tube at the moment just faces the pushing rod of the pushing device, namely, is in a state of waiting to receive the plate.
When the number of the plates pushed by the preamble received by the same 1 shaping die in a state of waiting to receive the plates reaches the set number, the shaping conveying drive is started, and the driving shaft drives the chain wheel to rotate N m times of teeth, namely N m/Zc, to stop; at this time, the adjacent shaping mold just aligns the pushing rod of the pushing device of the shearing pushing device of the drying and shearing device again, that is, the adjacent shaping mold is in a state of waiting to receive the plate again. Because the received plates are difficult to be tidy and are all positioned in the shaping mold, after the plates are received and rotated for a plurality of times, when a shaping mold which is used for receiving a set number of plates is rotated to be aligned with a shaping pressing plate of the shaping device, a shaping cylinder is started, a telescopic rod of the shaping cylinder extends out, the shaping pressing plate is driven to press down, and the plates extending out of the shaping mold are pressed into the shaping mold for shaping; then, the telescopic rod of the shaping cylinder is retracted, and the shaping pressing plate is driven to be lifted up again to a state of waiting to press down for shaping. In the process that the plate material slowly rotates from a short supporting leg to a long supporting leg of the bending forming frame along with the chain in the forming die, the plate material is gradually solidified, the performance is gradually stable, and the plate material is completely formed into a 'hat brim' core after bending forming when reaching the long supporting leg.

Compared with the prior art, the invention has the advantages that the bending forming device is arranged, and the forming die of the forming conveying device provides a good forming space for the sheet plate which is not completely formed; because the center distance L mx of the adjacent shaping dies (324) is N m times of the pitch P l of the chain (325), namely L mx=NmPl, when the driving chain wheel rotates N m times of teeth, namely N m/Zc, the adjacent shaping dies at the back just aim at the pushing rod of the pushing device of the shearing pushing device of the drying and shearing device again, thereby being convenient for the control and operation of equipment; due to the arrangement of the shaping device, when the shaping die rotates to be aligned with the shaping pressing plate of the shaping device, the plate which does not enter the shaping die can be pressed into the shaping die, so that the plate is ensured to be gradually solidified, and the performance of the plate is further improved.
