Two groups of positioning plates 2 that fit on the metal plate are fixed in sequence along the left and right directions on the back of the top of the support frame 1. The design of the blocking plate 7 improves the bending effect. The design of the positioning plate 2 can block and limit the metal plate so that it can remain parallel to avoid tilting and affecting the bending effect. An extension frame 8 is fixed on the top of the right side of the bracket 3. A reinforcing plate 23 is rotatably installed on the top of the front of the bracket 3. The support frame 1 is provided with an arc-shaped structure for plugging with the reinforcing plate 23. The bottom of the front of the reinforcing plate 23 is fixed with a convex plate, and the convex plate is inserted with a T-shaped lifting column 21.

A spring 22 is wound on the T-shaped lifting column 21, and the two ends of the spring 22 are fixed to the protruding end of the T-shaped lifting column 21 and the convex plate. By arranging the reinforcing plate 23, the arc-shaped groove 24, the T-shaped lifting column 21 and the spring 22, the elastic rebound of the spring 22 can be used to give the T-shaped lifting column 21 a pushing force, so that it can be quickly inserted into the support frame 1, so as to quickly position the reinforcing plate 23, and then it is convenient to use the reinforcing plate 23 to stably support the bracket 3, so as to prevent one end of the bracket 3 from falling due to excessive weight and affecting the bending effect;

[0021] Reference Figure 1-Figure 3, a sliding block 10 is provided in the extension frame 8 for sliding, an auxiliary cylinder 11 is embedded in the sliding block 10, a mounting frame 12 is fixed to the piston rod of the auxiliary cylinder 11, a pressing column 13 for pressing and bending the metal plate is fixed to the bottom of the mounting frame 12, a first slide 9 is provided on the front and back of the inner cavity of the extension frame 8, and the front and back of the sliding block 10 are inserted in the first slide 9 through convex strips, a second slide 14 is provided on the front and back of the extension frame 8, a sliding frame 15 is provided for sliding in the second slide 14, and each group of sliding frames 15 is inserted The bottom end of the T-shaped slide bar 16 is fixed on the mounting frame 12. The design of the first slide 9 can limit the sliding of the sliding block 10, thereby improving the stability of its movement. The design of the second slide 14, the sliding frame 15 and the T-shaped slide bar 16 can limit the sliding of the mounting frame 12, thereby improving the stability of the mounting frame 12 and the pressing column 13 during movement, thereby preventing one end from tilting. The width of the mounting frame 12 is smaller than the diameter of the pressing column 13, thereby preventing the mounting frame 12 from directly contacting the metal plate when moving downward, thereby preventing unnecessary wear on the metal plate. An auxiliary component is provided on the extension frame 8, which includes a fixed cylinder 4 embedded in the bracket 3, a piston rod of the fixed cylinder 4 is fixed with a pressing plate 5 whose bottom is attached to the metal plate, a T-shaped plate 6 with the bottom end fixed to the pressing plate 5 is inserted symmetrically on the bracket 3 along the front and rear directions, a motor 18 is fixed on the bracket 3, a Z-shaped frame 19 is fixed to the output shaft of the motor 18, an auxiliary vertical frame 20 is fixed to the left side of the sliding block 10, and one end of the Z-shaped frame 19 is inserted in the auxiliary vertical frame 20, and a plurality of pressure sensors are embedded symmetrically on the bottom of the pressing plate 5 along the front and rear directions. The right side of the top of the extension frame 8 and the front of the bottom of the pressing plate 5 are respectively fixed and embedded with displacement sensors 17 used in conjunction with the sliding block 10 and the support frame 1. By setting auxiliary components, the metal plate can be quickly pressed and positioned according to the thickness of the metal plate to avoid position displacement during bending, which affects the bending effect, and the position of the pressing column 13 can be accurately adjusted according to the thickness of the metal plate, so as to accurately control the different bending intervals required for metal plates of different thicknesses as needed.

Then the user rotates the reinforcing plate 23 into the arc groove 24, and uses the elastic rebound of the spring 22 to make the T-shaped lifting column 21 clamped on the support frame 1, and the reinforcing plate 23 is positioned, so that the bracket 3 can be supported as a whole. At this time, the user turns on the fixing cylinder 4 through the controller, thereby driving the pressing plate 5 to move down and contact the metal plate. At this time, the pressure sensor monitors the pressure change in real time to avoid excessive pressure damaging the metal plate. At this time, the user is located on the pressing plate 5. The displacement sensor 17 on the extension frame 8 also monitors the displacement changes in real time. At this time, the pressing plate 5 can quickly position the metal plate. Then the user turns on the motor 18 through the controller. The motor 18 drives the Z-shaped frame 19 to swing, so that with the cooperation of the auxiliary vertical frame 20, the sliding block 10, the auxiliary cylinder 11 and the pressing column 13 below it can be driven to move synchronously, and the displacement sensor 17 on the extension frame 8 monitors the displacement changes in real time. When the pressing column 13 moves to a suitable position according to the thickness value of the metal plate, the user turns on the auxiliary cylinder 11 through the controller, thereby driving the pressing column 13 to move downward to perform bending operations on the metal plate.
