At this time, only one of the driving rods needs to be rotated to drive the adjusting screw rods on both sides to rotate at the same time. Since the threads of the adjusting screw rods on both sides are opposite, the adjusting plates on both sides can be driven to move to the appropriate position at the same time.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. When loading, the side bars and rear bars can be used to limit the position within a certain range.

[0068] There are two adjusting plates 12-1, and they are symmetrically arranged in the workbench 1. The upper sides of the adjusting plates 12-1 are symmetrically welded and fixed with connecting blocks 12-2. The connecting blocks 12-2 are slidably arranged in the slide groove on the upper surface of the workbench 1, and the connecting blocks 12-2 are connected to the side block 11 after passing through the slide groove; a fixing frame 17 is arranged on the side of the side block 11 away from the center of the workbench 1, and the fixing frames 17 are arranged in an "L" shape, and the horizontal plate of the fixing frame 17 is movably inserted in the lower side wall of the side block 11, and the lower side of the horizontal plate of the fixing frame 17 is welded and fixed to the connecting block 12-2, and a plurality of resistance springs 18 are fixed on one side wall of the vertical plate of the fixing frame 17 at equal intervals, and the resistance springs 18 are embedded and fixed in the side block 11 adjacent thereto;

[0069] There are two adjusting screw rods 12-3, and they are symmetrically screwed in the workbench 1 through bearings. The threads of the adjusting screw rods 12-3 on both sides are oppositely arranged, and the rear side of the adjusting plate 12-1 is screwed on the adjacent adjusting screw rod 12-3 through threads; an electric push rod 19 is embedded and fixed inside the adjusting screw rod 12-3 on the right side, and a linkage rod 20 is fixed on the piston rod of the electric push rod 19.

[0070] Driving rod 12-4, there are two driving rods 12-4, and they are symmetrically connected to the front side of the two side walls of the workbench 1 through bearings. After the outer end of the driving rod 12-4 passes through the side wall of the workbench 1, it is exposed on the outside of the workbench 1, and the inner end of the driving rod 12-4 is connected to the corresponding adjusting screw 12-3 on the rear side through the synchronous wheel transmission assembly.

[0071] When using the present invention, according to the size of the plate to be bent, the corresponding driving rod 12-4 is rotated, and the driving rod 12-4 drives the corresponding adjusting screw 12-3 to rotate through the synchronous wheel transmission assembly, and the adjusting screw 12-3 drives the adjusting plate 12-1 to move, and the adjusting plate 12-1 drives the side baffle 11 to move through the connecting block 12-2 until the side baffle 11 moves to a suitable position. During the movement of the adjusting plate 12-1, the fixing frame 17 is driven to move through the connecting block 12-2, and the fixing frame 17 drives the side baffle 11 to move through the resisting spring 18 until the side baffle 11 moves to a suitable position.

At this time, only one of the driving rods 12-4 needs to be rotated to drive the adjusting screw rods 12-3 on both sides to rotate at the same time. Since the threads of the adjusting screw rods 12-3 on both sides are opposite, the adjusting plates 12-1 on both sides can be driven to move to the appropriate position at the same time. After the plate is clamped on the side stop bars 11 on both sides, when pressure is applied downward, the side stop bars 11 move along the horizontal side of the fixing frame 17, so that the contact spring 18 is compressed.

At this time, the sheet is adjusted along the inclined surfaces on the rear baffle 10 and the side baffle 11 until the sheet contacts the workbench 1. At this time, the bending effect is achieved through the cooperation of the lower module 5 and the upper module 4.

[0073] When the upper module 4 needs to be replaced, the limiting mechanism 8 is loosened, and the sliding bar 7 on the upper module 4 can be removed from the mounting plate 6. After the limiting block 8-1 is pushed into the movable groove 6-1, the sliding bar 7 is slid into the mounting plate 6, and the limiting block 8-1 rotates to the front side of the sliding bar 7 with the cooperation of the torsion spring and the connecting ring 8-4, and then the limiting motor 8-3 is started. The limiting motor 8-3 drives the limiting screw rod 8-2 connected thereto to rotate, and the limiting screw rod 8-2 drives another limiting screw rod 8-2 to rotate through the synchronous wheel transmission assembly. The two limiting screw rods 8-2 respectively drive the limiting block 8-1 to move through their respective nuts until the limiting block 8-1 hits the front end of the sliding bar 7, thereby achieving the limiting effect.

[0074] Compared with the prior art, the beneficial effects of this specific implementation are as follows:

[0075] 1. When loading materials, the side stop bar 11 and the rear stop bar 10 can be used to limit the position within a certain range. During the bending process, the position can be automatically adjusted through the inclined surfaces on the side stop bar 11 and the rear stop bar 10. There is no need to adjust the position of the plate 12-1 material multiple times, which improves work efficiency.

[0076] 2. The upper module 4 slides on the mounting plate 6 through the sliding block and can be limited by the limiting mechanism 8 at the same time, so as to facilitate the replacement of the upper module 4 and improve the stability of the upper module 4 after installation;

[0077] 3. The two adjusting screw rods 12-3 in the adjusting mechanism 12 can be connected through the linkage rod 20 and the electric push rod 19. When the middle end of the plate is bent, the two adjusting screw rods 12-3 can be connected to facilitate simultaneous adjustment of the side guard bars 11 on both sides;

[0078] 4. The limiting insert strips 21 on the two inner walls of the groove 1 - 1 on the workbench 1 can be inserted into the two side walls of the lower module 5 , so as to limit the lower module 5 and avoid the lower module 5 from deflecting.
