[0038] The supporting side plate portion 21 is fixedly arranged on one side of the forming base 1, and two groups of rotating disk portions 34 with intervals are arranged on the surface of the supporting side plate portion 21. A rotating arm 36 is fixedly arranged on the center of the rotating disk portion 34, and an inclined stopper 35 is arranged on the end surface of the rotating disk portion 34 away from the rotating arm 36. The two groups of rotating disk portions 34 are both disc-shaped and can rotate in the supporting side plate portion 21, and the rotating disk portion 34 is driven to rotate by rotating the operating rotating arm 36, thereby driving the inclined stopper 35 on the other side of the rotating disk portion 34 to rotate. A steel plate limit block 26 is arranged on one side of the supporting side plate portion 21, and a limit block slot 27 is opened on the surface of the steel plate limit block 26. The correction main block 29 is rotatably connected in the limit block slot 27 through the correction shaft 28. The steel plate limit block The side of 26 close to the steel plate is an inclined surface, so that the front end of the steel plate can enter between the two sets of steel plate limit blocks 26 distributed at a distance along the inclined surface, and the opposite surfaces of the two sets of steel plate limit blocks 26 are flush with the steel plate. At the same time, one end of the correction main block 29 is also flush with the steel plate after rotation, and an upwardly extending correction column 30 is fixed on the top of the correction main block 29. At the same time, a C-shaped correction side pressure plate 31 is fixed on the top of the correction column 30. When the correction main block 29 rotates, the correction side pressure plate 31 also rotates, and the side of the correction side pressure plate 31 is also flush with the steel plate. Therefore, when the steel plates are docked, the correction side pressure plate 31 can be rotated to align one end of the steel plate in a suspended state with the steel plate clamped at the steel plate roller 3, thereby realizing the correction of the steel plate deviation. The rotation of the correction main block 29 is driven by the correction push rod 32, and a group of correction push rods 32 connected to the correction main block 29 are in contact with the inclined surface of the inclined surface block 35. As the rotating disk portion 34 rotates, the front section of the correction push rod 32 gradually enters a higher position from the bottom slope of the inclined surface block 35, and the correction push rod 32 is restricted by the correction sleeve 33 slidingly sleeved outside the correction push rod 32, so that the correction sleeve 33 moves in a straight line, thereby realizing the pushing of the correction main block 29, and a driving connecting member 41 is provided at the connection between the correction push rod 32 and the correction main block 29, wherein one end of the driving connecting member 41 rotates with the inner wall of the correction main block 29, and the other end rotates with the connection with the correction push rod 32, wherein the other end of the correction sleeve 33 is connected to the supporting side plate portion 21 The surface of the transmission rod 40 is fixed, which can improve the stability of the correction push rod 32, and another group of inclined surface blocks 35 are connected to the transmission rod 40.

An arm slot 37 is provided on the surface of the rotating arm 36, and a movable cross grip 38 is slidably connected in the arm slot 37.Two groups of angle limit rods 39 with upper and lower spacing and L-shaped structures are fixed on the surface of the supporting side plate 21. The vertical part of the connection between the angle limit rod 39 and the supporting side plate 21 is greater than the distance from the center point of the rotating disk 34 to the center point of the rotating disk 34 from the farthest end of the rotating arm 36. When the rotating arm 36 rotates to a horizontal state, the movable horizontal grip rod 38 can be pushed in the arm slot 37, so that the movable horizontal grip rod 38 is located at the farthest end of the rotating arm 36, and the movable horizontal grip rod 38 can be pressed against the angle limit rod 39, so that the angle of the rotating arm 36 is limited, so that the steel plate is always in a limited state, without the need for manual long-term holding operation, saving manpower.

Since the bottom of the steel plate limit block 26 is an engaging sleeve arranged outside the positive and negative threaded rod 23, the two sets of steel plate limit blocks 26 can be driven by the driving motor 22 to move close to each other to a certain extent, so that the steel plate limit blocks 26 can limit steel plates of different widths. At the same time, in order to meet the driving action of rotating the correction main block 29 after the movement of the steel plate limit block 26, the front end of the correction push rod 32 is An internal thread is provided, and a telescopic screw portion 42 is threadedly connected to the internal thread, so that the front end of the telescopic screw portion 42 is in contact with the inclined stopper 35. After the threads of the telescopic screw portion 42 and the correction push rod 32 are extended and retracted, the stability can be improved by reinforcing bolts. A support block is fixedly provided on the top of the forming base 1, and the side wall of the support block is rotatably connected to a forming press-down piece 18.
