The working principle of the invention is as follows:

s1, in the initial state, the distance between the forming sliders 12 at the left and right opposite positions is the farthest, then according to the size of the straight line section of the tray, the lateral pressure bolt 32 is rotated to adjust the distance between the lateral pressure lower plate 30 and the lateral pressure upper plate 31, the lower pressure motor 25 at the middle position is started, the pressing motor 25 will drive the connected pressing screw 26 to rotate when working, the pressing screw 26 will drive the pressing connecting rod 23 connected with it through screw to make expansion and contraction change when rotating, thereby realizing the adjustment of the distance between the left and right opposite pressing blocks 24, starting the left and right pressing motors 25, the pressing motor 25 can drive the pressing screw 26 connected with it to rotate when working, the pressing screw 26 can drive the pressing connecting rod 23 connected with it through screw to make expansion and contraction change when rotating, therefore, the distance between the pressing blocks 24 which are opposite up and down can be adjusted, and the width and the height between the pressing blocks 24 can accord with the bending size of the plate 5.

S2, the starting cylinder 41 drives the shoring slide block 40 to move, so as to control the distance change between the left shoring support rod 42 and the right shoring support rod 42, so that the round rod 45 moves to a proper position in the shoring groove 100, the cut plate 5 is placed on the upper surface of the support 10, the position of the plate 5 is positioned in the middle between the two side pressing lower plates 30, then the first hydraulic cylinder 21 is started to push the lower pressing support rod 22 connected with the first hydraulic cylinder to move downwards, the pressing block 24 positioned below is matched with the support 10 to press the plate 5, the left end and the right end of the plate 5 are jacked up by the round rod 45 to a certain height, then the forming motor 13 is started, the forming screw 14 is driven to rotate when the forming motor 13 works, the forming screw 14 drives the forming slide block 12 to slide in the forming slide way 11 towards the direction of the forming motor 13, the forming slide block 12 drives the side pressing lower plates 30 and the side pressing upper plates 31 to move towards the middle of the support 10, when the plate 5 is just contacted with the side pressing lower plates 30, the end face of the plate 5 slides upwards to contact with the surface of the belt 301 due to the extrusion of the side pressure lower plate 30, the plate 5 pushes the belt 301 to move until the end face of the plate 5 is separated from the belt 301 and contacts with the side pressure upper plate 31, and at this time, the lateral pressure lower plate 30 moves to a distance from the round bar 45 equal to the length of the round bar 45, the round bar 45 can rotate just to be horizontal to the top supporting groove 100 under the action of the rack 46 and the gear 43, and then when the lateral pressure lower plate 30 continues to move towards the middle of the support 10, the pressing block 24 combines the side pressing lower plate 30, the side pressing upper plate 31 and the upper pressing plate 33 to bend the plate 5 into an Contraband-shaped structure with an upward opening, then the hydraulic cylinder II 35 is started to push the upper pressing plate 33 to rotate by taking the arc-shaped center line of the upper pressing support rod 34 as an axis, the upper pressing plate 33 can bend the Contraband-shaped structural plate 5 with the upward opening again by an angle of 90 degrees, and thus a blank of a straight line section of the tray can be manufactured.

And S3, the pressing block 24 is restored to the initial state and then is separated from the tray, the lower plate 30 is pressed to the initial position, the bent tray is taken down, and the process is repeated to process the next plate 5.
