The roller comprises a flat roller 11 with a flat peripheral surface and a corrugated roller with roller teeth arranged on the peripheral surface, the roller teeth on the corrugated roller extend along the axial direction of the roller, after a rolled metal plate is contacted with the roller, the roller teeth can roll a corrugated slope on the metal plate along with the rotation of the roller, and the flat roller 11 can roll a flat plane on the metal plate. Wherein, the ripple roller includes two kinds of different roller tooth structures, as shown in fig. 1 to 10, wherein one kind of ripple roller is the protruding processing ripple roller 3 that can process protruding structure on ripple face domatic, and another kind of ripple roller is the draw-in groove processing ripple roller 1 that can process draw-in groove 9 structure on ripple face domatic, and the ripple face of the metal sheet that two kinds of ripple rollers were made can intermesh, and wherein, draw-in groove 9 and the protruding 10 of pre-clip size the same and mutually match, when making the metal sheet mesh together through the ripple face, the protruding 10 of pre-clip on the ripple face meshing position can with draw-in groove 9 joint, and then makes two metal sheets all cooperate closely in its face extending direction and range upon range of orientation. The metal plate defining the rolled card slot 9 is a first metal plate 5, the surface of the first metal plate 5 containing the card slot 9 is a first corrugated surface 6, the metal plate defining the rolled pre-card protrusion 10 is a second metal plate 7, and the surface of the second metal plate 7 containing the pre-card protrusion 10 is a second corrugated surface 8. The metal plate used in this example was a 3mm thick T2 industrial pure copper plate with a rolling mill control reduction of 50%.
As shown in fig. 2, hemispherical roller protrusions 2 are disposed on two opposite slope surfaces of each roller tooth in the corrugated roller 1 for clamping groove processing, so that hemispherical clamping grooves 9 can be formed on two opposite slope surfaces in the corrugated groove of the first corrugated surface 6. As shown in fig. 4, hemispherical grooves are formed on two opposite slope surfaces of each tooth of the embossing corrugating roller 3, so that hemispherical pre-clamping protrusions 10 can be formed on two opposite slope surfaces of the corrugated edges of the second corrugating surface 8. As shown in fig. 2, the roller projections 2 on opposite tooth surfaces between the teeth of the neck-finish corrugated roller 1 are in one-to-one correspondence and the corresponding roller projections 2 are arranged in an extending direction perpendicular to the tooth surfaces, so that the corresponding neck grooves 9 in the corrugated grooves of the first corrugated surface 6 are arranged in an extending direction perpendicular to the corrugated grooves. As shown in fig. 4, the grooves 4 on opposite tooth surfaces between the teeth of the embossing corrugating roller 3 are in one-to-one correspondence and the corresponding grooves 4 are arranged in the extending direction perpendicular to the tooth surfaces, so that two pre-clamping projections 10 on opposite corrugation edges on the second corrugation surface 8 are arranged in the extending direction perpendicular to the corrugation edges.
In the working process of the roller in this embodiment when rolling a metal plate, as shown in fig. 5 to 8, when the first surface of the first metal plate is processed by using the clamping groove processing corrugated roller 1 in fig. 5 and 6, the flat roller 11 is matched with the clamping groove processing corrugated roller 1 on the second surface of the first metal plate on the lower side of the first metal plate 5, so that the first surface of the rolled first metal plate is the first corrugated surface 6 with the clamping groove 9, and the second surface of the first metal plate is a plane. In the same way, when the first surface of the second metal plate is processed by adopting the protrusion processing corrugated roller 3 in fig. 7 and 8, the flat roller 11 is matched with the protrusion processing corrugated roller 3 on the second surface of the second metal plate at the lower side of the second metal plate 7, so that the first surface of the rolled second metal plate is the second corrugated surface 8 with the pre-clamping protrusions 10, and the second surface of the second metal plate is a plane.
In this embodiment, the maximum groove depth of the corrugated groove that the corrugated roller can process is the amplitude of the corrugated roller (L in fig. 2). When the size processing of the pre-clamping protrusion 10 and the clamping groove 9 is too small, the combination effect of the clamping groove 9 and the pre-clamping protrusion 10 after the rolling of the composite board is poor, and when the size processing of the pre-clamping protrusion 10 and the clamping groove 9 is too large, the pre-clamping protrusion 10 may not fully fill the clamping groove 9, and the rolling cooperation of the composite board is in the condition of clamping stagnation or falling off. The rolling effect of the composite plate is optimal when the spherical radius (r in fig. 2) of the pre-clamping protrusion 10 and the clamping groove 9 is 10 to 60 percent of the amplitude of the corrugated roller through continuous experiments and verification of the rolling effect.
The specific steps of the metal plate rolling composite method in the embodiment are as follows:
step (1): a first corrugated surface 6 is rolled on a first metal plate surface of a first metal plate 5 by using a clamping groove processing corrugated roller 1, a second corrugated surface 8 is rolled on a second metal plate surface of a second metal plate 7 by using a protrusion processing corrugated roller 3, the first corrugated surface 6 and the second corrugated surface 8 can be matched with each other in a fit mode, a clamping groove 9 is formed on the first corrugated surface 6, and a pre-clamping protrusion 10 matched with the clamping groove 9 is formed on the second corrugated surface 8;
after the step (1) is finished, the step (2) is carried out, and the process of the step (2) is as follows: stacking the first metal plate 5 and the second metal plate 7 together, enabling the first corrugated surface 6 and the second corrugated surface 8 to be matched, enabling the pre-clamping protrusions 10 on the second corrugated surface 8 to be clamped into the clamping grooves 9 on the first corrugated surface 6, and enabling the clamping grooves 9 to limit separation of the pre-clamping protrusions 10 along the stacking direction of the first metal plate 5 and the second metal plate 7 after the clamping grooves 9 are clamped with the pre-clamping protrusions 10;
after the step (2) is finished, the step (3) is carried out, and the process of the step (3) is as follows: the first metal plate 5 and the second metal plate 7 are pre-fixed and then subjected to rolling and compounding.
