the steel plate is driven to be conveyed backwards from the gap between the upper press roll 2 and the lower press roll 3, one side of the steel plate penetrates through the gap to extend outwards, and the outwards extending side of the steel plate is guided to be turned upwards due to the arrangement of the turning roll 4; purlines with different thickness specifications can be processed in the production process, so that the processed steel plates have various thickness specifications;
the gap between the upper compression roller 2 and the lower compression roller 3 needs to correspond to the thickness of a steel plate, the upper compression roller 2 is arranged on the adjustable mounting frame 5, and therefore the adjustable mounting frame 5 needs to be adjusted, due to the arrangement of the inclined adjusting hole 13 and the third locking limiting rod 51, the adjustable mounting frame 5 is limited to move along the inclined direction of the inclined adjusting hole 13, so that the upper compression roller 2 can simultaneously move inwards in a transverse mode while the adjustable mounting frame 5 is adjusted to adjust the adjusting gap between the upper compression roller 2 and the lower compression roller 3, the included angle between the turnover roller 4 and the horizontal plane is alpha, the included angle between the inclined adjusting hole 13 and the horizontal plane is beta, and the angle relationship between the alpha and the beta is 180 degrees;
therefore, when the upper press roll 2 is adjusted, the vertical distance from the lower end point of the outer side of the upper press roll 2 to the outer wall surface of the turnover roll 4 is equal to the gap height between the upper press roll 2 and the lower press roll 3, namely the thickness of the matched steel plate, and the size precision of a product in the process of adjusting equipment according to the thickness of the steel plate is ensured.
The adjusting shaft holes 141 of the side supporting plates 14 on the frame 1 of each of the upper folding row a and the adjustable folding row B are coaxially arranged, and the adjusting shaft 56 passes through each adjusting shaft hole 141 to synchronously drive each eccentric wheel 57 to extrude towards the corresponding compression bolt 55, so as to synchronously adjust the positions of the adjustable mounting frames 5 of each of the upper folding row a or the adjustable folding row B, and further synchronously adjust the gap between the upper press roll 2 and the lower press roll 3. Because the eccentric wheel 57 is adjusted by extruding the compression bolt 55, and the compression bolt 55 and the transverse extension plate 524 of the adjustable mounting frame 5 can be adjusted in vertical position by respectively adjusting the compression bolt 55 and the transverse extension plate through threads, the adjustable mounting frame 5 of each compression roller mechanism can be adjusted in position adaptive fine adjustment independently, and errors generated in production and assembly are repaired.
The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
