[0029] When processing plate material of different thicknesses at different angles, the angle of rolling tool head 2 can be changed by tilting mounting frame 1, and the angle of laser head 6 on mounting frame 1 is adjusted by first driving member 7, so as to adjust the light spot irradiation point of laser head 6, so as to optimize the heating effect on plate material of different angles and different thicknesses.

[0030] The second driving member 8 is used for rotating the cylinder 3, and the cylinder 3 drives the movable plate 4 to rotate, at this time, the mounting frame 1 and the laser head 6 are directly rotated to form a fan, and the angle between the rolling direction of the rolling tool head 2 and the fan is changed, and the first driving member 7 can move the light spot position of the laser head 6.

[0031] The metal plate has various materials, and the best plastic state temperature of part of the plate is relatively high, and a preheating mode is generally used, that is, the light spot of the laser head 6 is moved forward, and through the cooperation of the second driving member 8 and the first driving member 7, the light spot position of the laser head 6 can be moved forward according to the material of the processed plate, so that the heating effect of the laser head 6 on different materials of the plate is optimized.

[0032] The rolling forming structure of the utility model discloses through the cooperation design of the first driving member 7 and the second driving member 8, compared with the prior art, the freedom degree of the laser head 6 can be improved obviously, the light spot position of the laser head 6 is changed, and the heating effect of the laser head 6 on the plate with different thicknesses, different angles and different materials is optimized, so that the energy utilization rate is improved.

[0033] As shown in Figure 1 and Figure 4 , the first driving member 7 includes a connecting plate 701 connected with the side surface of the cylinder 3, the connecting plate 701 is coplanar with the end of the cylinder 3, the end of the connecting plate 701 is hinged with an electric push rod 702, the fixed end of the electric push rod 702 is hinged with the electric push rod 702, and the output end of the electric push rod 702 is hinged with the movable plate 4, because the connecting plate 701 is fixed, when the output end of the electric push rod 702 is stretched out, the included angle between the electric push rod 702 and the connecting plate 701 is increased, at this time, the movable plate 4 can be driven to rotate along the hinged point in the direction away from the connecting plate 701, and at the same time, the structure at this position is triangular, and has good stability.

[0034] As shown in Figure 3 and Figure 4 , the second driving member 8 includes a cylindrical block 801 arranged on the mounting frame 1, the rolling tool head 2 is rotatably arranged on the outer side of the cylindrical block 801, the end of the cylindrical block 801 is provided with a cylindrical groove 802, the motor 803 is arranged in the cylindrical groove 802, the output end of the motor 803 penetrates the mounting frame 1 and is connected with the cylinder 3, and the cylinder 3 can be driven to rotate when the motor 803 works, in the above design, the motor 803 can be hidden in the cylindrical block 801, that is, through reasonable layout, the space can be effectively utilized, and the occupied volume of the device is reduced.

[0035] As shown in Figure 2 and Figure 4As shown, the mounting frame 1 is provided with an arc-shaped sliding groove 9, and the end of the connecting plate 701 is connected with a mounting block 10 which is in sliding cooperation with the arc-shaped sliding groove 9. Through the cooperation of the mounting block 10 and the arc-shaped sliding groove 9, the movement of the connecting plate 701 is guided, and the connecting plate 701 is protected so as not to be deformed in long-term use.

[0036] As shown in Figure 1 , Figure 2 and Figure 4 , the mounting plate 5 is provided with a sliding groove 11, and the laser head 6 is in sliding cooperation with the sliding groove 11. The mounting frame 1 is provided with an adjusting member 12 for adjusting the position of the laser head 6 in the sliding groove 11. During the angle adjustment of the laser head 6, the output end of the laser head 6 gradually moves away from the plate. Through the above design, the laser head 6 can slide in the sliding groove 11 according to the adjustment angle of the laser head 6, so that the output end of the laser head 6 always maintains a close distance to the plate.

[0037] As shown in Figure 1 and Figure 4 , the adjusting member 12 includes a first connecting rod 1201 connected with the fixed end of the electric push rod 702, and the end of the first connecting rod 1201 is connected with the laser head 6 through a steel rope 1202. The mounting plate 5 is arranged in an inclined manner at the end of the movable plate 4, and the end of the mounting plate 5 close to the movable plate 4 is located in the output direction of the laser head 6. The mounting frame 1 is connected with a second connecting rod 1203 which is located at the top of the arc-shaped sliding groove 9 and has a lifting ring 1204 at the end thereof. The first guide wheel 1205 and the second guide wheel 1206 are rotatably arranged on the mounting plate 5, and the second guide wheel 1206 is located at the end of the sliding groove 11. The steel rope 1202 passes through the lifting ring 1204, the first guide wheel 1205 and the second guide wheel 1206 in sequence, and is connected with the first connecting rod 1201. The steel rope 1202 first passes through the lifting ring 1204, then passes around the first guide wheel 1205 and the second guide wheel 1206 in sequence, and is connected with the laser head 6 in the sliding groove 11.

[0038] As shown in Figure 4As shown, when the electric push rod 702 is fully extended, the end of the movable plate 4 moves away from the connecting plate 701, that is, the first guide wheel 1205 and the second guide wheel 1206 move away from the first connecting rod 1201. At this time, the steel cable 1202 between the two is longer and is in a taut state, which can pull the laser head 6 to move in the receiving groove so that the laser head 6 is in a fully retracted state. When the electric push rod 702 gradually retracts, the end of the movable plate 4 gradually approaches the connecting plate 701, that is, the first guide wheel 1205 and the second guide wheel 1206 move toward the first connecting rod 1201, and the steel cable 1202 between the two becomes shorter. The laser head 6 can move in the receiving groove under the action of gravity and pull the steel cable 1202. At this time, the moving distance of the laser head 6 is closely related to the adjustment angle of the electric push rod 702 on the laser head 6 so that the output end of the laser head 6 can be close to the plate.

[0039] When the cylinder 3 rotates to move the irradiation spot of the laser head 6 forward, the mounting block 10 moves toward the lifting ring 1204. At this time, the first connecting rod 1201 is close to the lifting ring 1204, and the steel rope 1202 between them becomes shorter. The laser head 6 can move in the receiving groove under the action of gravity. That is, the moving distance of the laser head 6 is closely related to the forward movement distance of the irradiation spot of the laser head 6, and the output end of the laser head 6 can be close to the plate.

[0040] In summary, the specific function of the adjusting component 12 is to link the movement of the laser head 6 with the first driving component 7 and the second driving component 8, so that no additional driving components are needed.

[0041] like Figure 4 As shown, a counterweight 13 is connected to the end of the steel rope 1202 and is connected to the laser head 6 through the counterweight 13. The counterweight 13 is a stainless steel block used to increase the weight of the laser head 6 and provide power for its movement in the sliding groove 11 so that the laser head 6 can pull the steel rope 1202.

[0042] like Figure 1 and Figure 4 As shown, an annular block 14 is connected to the mounting plate 5 and is located at the end of the sliding groove 11. Here, the end of the sliding groove 11 is located in the output direction of the laser head 6. The outer side of the laser head 6 is slidably engaged with the inner side of the annular block 14. When the laser head 6 is fully extended out of the sliding groove 11, its end can be slidably inserted into the inner side of the annular block 14. That is, the extended end of the laser head 6 can be fixed by the annular block 14, so that it is not easy to vibrate when rolling the plate.
