[0012] A billboard punching method is also provided, which is used to operate a metal billboard punching device, comprising the following steps:

[0013] S1: The blank metal plate is adsorbed and positioned by several sets of magnetic blocks, and then the second motor drives the slide table and the cylinder drives the U-shaped frame to move up and down, realizing automatic picking work and replacing manual operation;

[0014] S2: The motor 1 drives the four sets of driving blocks and the sliders to slide synchronously along the four sets of sliding sleeves, so as to bring the four sets of sliding frames at the upper ends of the four sets of sliding blocks closer or wider, and to center and correct the blank metal plate;

[0015] S3: When the four sets of sliding frames are synchronously unfolded, the two sets of top blocks are driven to rotate along the circular axis for one circle, and the blank metal plate after stamping is lifted upward, while the blank metal plate is lifted upward on all sides at the same time, to prevent the concave and convex three-dimensional marking position of the blank metal plate after stamping from being stuck in the groove of the groove module.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Place the blank metal plate on the upper end of the U-shaped frame, use several groups of magnetic blocks to adsorb and position the blank metal plate, cooperate with the limit sleeve to prevent the blank metal plate from falling, and then use the second motor to drive the screw rod to rotate, drive the slide to slide backward along the slide rail, drive the blank metal plate on the U-shaped frame to move to the upper position of the groove module, and then use the cylinder to drive the U-shaped frame to move downward and sleeve on the outside of the groove module. At the same time, the blank metal plate stays at the upper end of the groove module, and the U-shaped frame is separated from the blank metal plate. After the work is completed, the cylinder lifts the U-shaped frame to absorb the stamped blank metal plate, and takes the blank metal plate out, realizing automatic picking work, replacing manual operation, reducing the physical labor of workers, and ensuring personal safety in the production process.

[0018] 2. When placing the blank metal plate, the motor drives the gear to rotate, and the driving gear ring rotates along the two sets of fixed sleeves. The rotating gear ring drives the four sets of driving blocks and the sliders to slide synchronously along the four sets of sliding sleeves through the four sets of guide openings opened on the inner side, so as to realize the closing or expansion of the four sets of sliding frames at the upper ends of the four sets of sliders. At the same time, the blank metal plate will be centered and corrected, so that each stamping of the convex module can be accurate.

[0019] 3. When the four sets of sleeves and sliding frames are synchronously unfolded, the round rod is driven to move under the frame bar, and the gear 2 is driven to rotate by the meshing rack frame, and at the same time, the two sets of top blocks are driven to rotate along the circular axis for one circle. When the top block rotates, the stamped blank metal plate will be lifted upward, and when the two sets of round rods move to the side away from the fixed frame, they will contact the two sets of guide plates, lift the two sets of round rods, the sliding frame, and the gear 2 upward, and the positioning film is inserted into the upper set of slots, and the compression spring is stretched at the same time, and the gear 2 is separated from the rack frame, so that when the four sets of sliding frames are brought together to correct the blank metal plate, the top block will not be driven to rotate, and then contact the guide plates on both sides close to the fixed frame, which will drive the two sets of round rods to move downward, and the compression spring pulls the sliding frame and gear 2 to move, and gear 2 meshes with the rack frame again to prepare for the next four sets of top block lifting work, so as to prevent the concave and convex three-dimensional mark position of the stamped blank metal plate from being stuck in the groove of the groove module, affecting the subsequent work fluency.

[0020] 4. The hydraulic cylinder pushes the cover plate and the convex module to slide downward along the two groups of support columns, and at the same time compresses the two groups of return springs. The convex module punches the blank metal plate placed on the upper end of the groove module to stamp a concave and convex three-dimensional logo, so that the logo has a distinct three-dimensional sense and a better visual effect.
