In order to ensure the safety of the staff, the existing tongue and groove plate bending and forming device generally does not use the method of the staff holding the tongue and groove plate by hand to fix the tongue and groove plate to prevent the tongue and groove plate from being displaced during the bending process. The tongue and groove plate is limited in the front, back, left and right directions to prevent displacement. Because the tongue and groove plate has different specifications, the limit plate of the tongue and groove plate needs to be adjusted. The existing adjustment method mainly uses the rotation of the threaded rod to move downward to the surface of the limit plate for pressing, but when adjusting in the front, back, left and right directions, the limit plate is easy to rotate, so that the limit plate cannot limit the tongue and groove plate, resulting in the need to be very careful to align and adjust during adjustment, making the adjustment process very troublesome.

[0023] The pushing mechanism 6 includes a second supporting plate 601 fixedly connected to the upper sides of the base 1, a threaded rod 602 is threadedly connected to the inner side of the second supporting plate 601, and a pressing plate 603 is rotatably connected to the lower end of the threaded rod 602. The pressing plate 603 is connected to the second supporting plate 601 in a vertical sliding connection, and the front and rear sides of the pressing plate 603 are connected to the inner wall of the second supporting plate 601 in a vertical sliding connection. The pressing plate 603 is connected to the threaded rod 602 in a rotating connection. A first sliding block 611 is provided on the inner side of the first sliding groove 604, and the outer side surface of the first sliding block 611 is fitted with the inner side surface of the first sliding groove 604, and the left end width of the first sliding groove 604 is greater than the right side width of the first sliding groove 604, so that the first sliding block 611 will not slide when sliding on the inner side of the first sliding groove 604, and the first sliding block 611 will not move the inner side of the first sliding groove 604, and the right side of the first sliding block 611 is fixedly connected to a connecting plate 605, which connects The connection mode between the plate 605 and the first connecting rod 606 is a vertical sliding connection, and the connection mode between the first connecting rod 606 and the second sliding block 610 is a fixed connection, so that when the connecting plate 605 moves up and down, it will not drive the second sliding block 610 to move up and down, and the second sliding block 610 can drive the connecting plate 605 to move forward and backward by sliding forward and backward. The first connecting rod 606 is arranged on the right side of the connecting plate 605, and the second connecting rod 607 is arranged below the first connecting rod 606. The upper right end of the second connecting rod 607 is fixedly connected to the bearing plate 608, and a second sliding groove 609 is arranged inside the upper part of the second connecting rod 607. The second sliding block 610 is arranged on the inner side of the second sliding groove 609. The left end face of the second sliding groove 609 is connected to the left end face of the second connecting rod 607, and the inner side face of the second sliding groove 609 is in contact with the inner side face of the second sliding block 610, so that the second sliding block 610 can move out of the second sliding groove 609.

[0024] A guide hole 8 is provided on the inner side of the connecting plate 605, and the centering mechanism 7 includes a guide rod 701 provided on the inner side of the guide hole 8, and a limit plate 702 provided on the left end of the guide rod 701. The limit plate 702 is connected to the second support plate 601 in a sliding manner, and the lower end of the limit plate 702 is matched with the limit groove 703 in a clearance fit, and the left side surface of the limit groove 703 is not connected with the left side surface of the connecting plate 605. A limit groove 703 is provided on the lower inner side of the second connecting rod 607. The appearance structure of the guide hole 8 is inclined, and the guide hole 8 is matched with the guide rod 701 in a clearance fit, so that when the guide hole 8 moves upward, the guide rod 701 can be pushed to move to both sides.

[0025] When the position of the supporting plate 608 needs to be adjusted, the threaded rod 602 is rotated to drive the pressure plate 603 to leave the upper surface of the second connecting rod 607, so that the second connecting rod 607 can move left and right and forward and backward. When moving left and right, the second connecting rod 607 is constrained by the second slider 610 to move along the trajectory of the second slide groove 609. When moving forward and backward, the second connecting rod 607 drives the first connecting rod 606 and the connecting plate 605 to move forward and backward, and drives the first slider 611 to move on the inner side of the first slide groove 604, so that the movement of the supporting plate 608 and the first connecting rod 606 will be constrained, and no rotation will occur, resulting in the inability of the supporting plate 608 to limit the tongue and groove plate, and no calibration is required, thereby achieving the purpose of simplifying the fixing process.

[0026] When the threaded rod 602 moves downward a certain distance, the second connecting rod 607 can move, and the connecting plate 605 moves upward a certain distance. At this time, the limiting plate 702 is still on the inner side of the limiting groove 703, and the left side surface of the limiting groove 703 is not connected to the left side surface of the connecting plate 605. The limiting plate 702 will not move out of the inner side of the limiting groove 703, thereby avoiding the second connecting rod 607 being pulled out due to moving too far and needing to be reinstalled, thereby achieving the purpose of reducing the possibility of the bearing plate 608 falling off.

[0027] When it is necessary to replace the supporting plate 608, continue to rotate the threaded rod 602 upward, driving the connecting plate 605 and the guide hole 8 to move upward, the opening distance of the guide rod 701 and the limiting plate 702 is larger, and the limiting plate 702 moves out from the inner side of the limiting groove 703, losing the limiting position on the second connecting rod 607, and the supporting plate 608 can be replaced.
