In an embodiment of the present invention, the driving device is mounted on the mounting bracket 3, and comprises a motor 1 and a driving shaft 5. The motor 1 drives the driving shaft 5 to rotate, and further drives the driving roller 7 to rotate. However, this is not a limitation of the present invention, and other power devices for rotating the driving shaft 5 may be used.

The driving roller 7 is connected to the driving shaft 5 to follow the rotation of the driving shaft 5. And the axis of the driving roller 7 is perpendicular to the traveling direction of the sheet material to be processed and parallel to the surface of the sheet material to be processed. Furthermore, the generatrix of the active roller 7 is tangent to the surface of the sheet to be worked (as shown in figure 1).

The direction indicated by the arrow in fig. 2 is the traveling direction of the sheet material to be processed, and indicates that the sheet material is directed from upstream to downstream in the traveling direction. The surface of the plate material to be processed is the surface of the plate material when the plate material is spread out flat, and is also the plane in the width direction of the spread out flat plate material, and is the surface where the arrow is located in fig. 2.

As shown in fig. 2, the adjustment roller 11 includes a shaft portion 15 rotatably connected above the processing portion 13, and the shaft portion 15 is detachably mounted on the mounting bracket 3. In one embodiment of the present invention, the shaft portion 15 is mounted to the mounting bracket 3 in a bolt connection. Therefore, the position of the shaft part 15 on the mounting bracket 3, namely the relative position between the processing part 13 and the driving roller 7 can be adjusted by the bolt, so as to be suitable for processing plates with different thicknesses.

The processing portion 13 is rotatably connected below the shaft portion 15 and has a larger diameter than the shaft portion 15. And, the generatrix of the working portion 13 is parallel to the generatrix of the driving roller 7 with a preset gap therebetween for sandwiching the plate material to be worked therebetween (as shown in fig. 2).

By replacing the processing portions 13 of different diameters, the preset gap size can also be increased or decreased to the thickness of the plate to be processed.

The plate limiting device comprises a first pressing roller 17, a second pressing roller 19 and a third pressing roller 21. The first press roller 17, the second press roller 19 and the third press roller 21 are all arranged on the mounting bracket 3 in a relatively rotating mode. In an embodiment of the invention, the connection to the mounting bracket 3 is via a bearing. Wherein the first press roller 17 is located at the rightmost side in the drawing (i.e., an upstream position in the traveling direction of the sheet material to be processed); the second press roller 19 is located between the second press roller 17 and the third press roller 21; the third press roller 17 is located at the leftmost side in the drawing (i.e., a downstream position in the traveling direction of the sheet material to be processed). In particular, in one embodiment of the invention, the three press rolls have the same diameter and their axes of rotation are located in the same plane, so that the work surface is also located in the same horizontal plane and parallel to the end surface of the sheet to be worked. The "machined surface" refers to a plane where generatrices of the first press roller 17, the second press roller 19, and the third press roller 21 are located. The end face of the plate to be processed means a thin and long plane in the thickness direction of the plate to be processed. Those skilled in the art will understand that it is only necessary to ensure that the generatrices of the first pressing roller 17, the second pressing roller 19, and the third pressing roller 21 are parallel to the end face of the plate to be processed, and the three pressing rollers are not limited to have the same specification.

In one embodiment of the present invention, the plate radian adjusting device includes a driven roller 9, a guide rod and guide wheel 25, and a tension spring 27.

The driven roller 9 is rotatably connected to the mounting bracket 3 and has an axis parallel to the axes of the driving roller and the adjusting roller. The driven roller 9 is located downstream of the driving roller 7, and may be located upstream of the driving roller 7. The generatrix of the driven roller 9 is tangent to the surface of the sheet to be processed, so as to exert a force on the sheet to be processed. The axis of the driven roller 9 rotates by taking the axis of the driving roller 7 as the center of a circle so as to adjust the radian of the plate to be processed. The driven roller and the driving roller are positioned on the same side of the plate to be processed; the adjusting roller is positioned at the opposite side of the plate to be processed.

The working principle of the rolling processing equipment for the sheet large-diameter plate provided by the utility model is described below.

In the initial state, a proper gap is reserved between the adjusting roller 11 and the driving roller 7 by adjusting the adjusting screw 23 on the adjusting roller 11, so that the thickness of the plate to be processed is the thickness of the plate to be processed.

As shown in fig. 3, the position of the driven roller 9 is adjusted according to the desired working radius of the sheet material to be worked (corresponding to the arc α or β in the figure, respectively). In fig. 3, the axis O1 of the driving roller 7 and the axis O2 of the steering roller 11 are on a straight line (center line), and the straight line is fixed. The axis of the driven roller 9 can be adjusted to rotate around the axis O1 of the driving roller 7, but the adjustment range is limited by a method of: a tangent line E of the driving roller 7 is perpendicularly intersected with a straight line connecting the axes O1 and O2, and a tangent line F of the driven roller 9 is intersected with the tangent line E of the driving roller 7 as shown in fig. 3, thereby determining any value between an intersection angle γ which is larger than 0 ° and smaller than 180 °, as shown by a circle a in fig. 3, wherein γ is an adjustment angle range within which the axis of the driven roller 9 rotates around the axis of the driving roller 7.

The radius of the sheet to be machined determines the machining arc alpha or beta. The circle centers O3 and O4 of the plate to be processed are both positioned on the circle center line. In fig. 3, a circle B and a circle C corresponding to the center O3 or O4 of the circle respectively schematically represent the formed shapes of the plate to be processed.

And determining the position of the center O3 or O4 from the tangent point between the adjusting roller 11 and the driving roller 7 on the circle center line according to the radius of the plate to be processed. Then, based on the center O3 or O4, the circle B and the circle C are determined with radii, and the intersection with the circle a is found.

The shaft center of the driven roller 9 is moved to the intersection position by pulling the guide bar and the guide wheel 25 by the tension spring 27. As shown in fig. 3, when the plate material indicated by circle B needs to be processed, the driven roller 9 is adjusted to the position indicated by the solid line; when it is desired to machine the sheet material indicated by circle C, the driven roller 9 is adjusted to the position indicated by the broken line.

And then, entering a working state. The motor 1 is turned on to feed the sheet to be processed between the driving roller 7 and the adjusting roller 11 in a state where the surface of the sheet to be processed is parallel to the driving roller 7 and the adjusting roller 11.

That is, in fig. 2, the gap between the driving roller 7 and the steering roller 11 is inserted from right to left. When the plate to be processed advances, the end surface of the plate to be processed is restrained from shaking by the first pressing roller 17 and the second pressing roller 19, so that the plate to be processed advances smoothly.

Then, the plate to be processed enters between the driving roller 7 and the adjusting roller 11. The motor 1 drives the driving roller 7 and the adjusting rollers 11 driven to rotate oppositely to extrude the plate to be processed. The sheet to be processed continues downstream, being sandwiched between the driven roller 9 and the adjusting roller 11. Since the driven roller 9 has been adjusted to the intersection position, the sheet to be processed is pressed by the driven roller 9, and is bent and deformed in the direction of the adjustment roller 11, thereby forming an appropriate arc in motion. Meanwhile, the third press roller 21 applies downward pressure to the sheet to be processed to maintain smooth advance of the sheet to be processed.

After rounding, the plate to be processed can be wound into a cylinder, the generatrix of the cylinder is parallel to the axes of the driving roller 7, the adjusting roller 11 and the driven roller 9, the end surface of the cylinder is horizontal, and the two ends can be welded to form a complete cylinder. The adjusting roller 11 is lifted upwards, the adjusting screw 23 can be separated from the limiting groove, the adjusting roller 11 is separated from the equipment, and then the rolled cylinder can be taken out. More preferably, the secondary rounding can be carried out, and the processing precision is improved.

Therefore, the utility model provides a sheet metal class major diameter panel rounding processing equipment has following technological effect:

1) Since the sheet to be processed enters in the vertical direction (i.e., the width direction is the standing direction), it is not limited in the length direction, and is suitable for a sheet to be processed of any length;

6) Can carry out secondary rounding, and has compact structure and lower cost.

The above has described the sheet type large-diameter plate rounding processing equipment provided by the present invention in detail. Any obvious modifications thereof, which would be obvious to a person of ordinary skill in the art, without departing from the essential teachings of the invention, would constitute a violation of the patent rights of the invention and would bear corresponding legal obligations.
