Generally, the support provides a support and moving track for the upper module, and the primary oil cylinder is a power source for the movement of the whole upper module.
The upper die set comprises a first-stage upper die 5 and a second-stage upper die 6; the lower end of the second-stage upper die 6 is provided with a sharp part; a concave part is arranged on one side above the sharp part; the angle of the concave part is 60-100 degrees, and the special sharp part can enable the secondary upper die to press a bevel on the flat board surface; the depression may be formed by pressing successive corners so that the pressing of the next corner is not affected by the previous corner. On the other hand, when two surfaces of the folded angle need to be pressed further, the one-level upper die with the smoother bottom end can be selected for pressing.
The primary upper die 5 is connected with a telescopic rod of the primary oil cylinder; furthermore, the first-level oil cylinder directly controls the first-level upper die to move, the first-level upper die comprises a downward convex die pressing part, the low end of the die pressing part is flat, and the first-level upper die or the second-level upper die can be selected to bend the plate according to needs. A secondary oil cylinder 7 is fixed inside the primary upper die; the telescopic rod of the secondary oil cylinder extends downwards and is fixedly connected with the secondary upper die 6; the second-stage upper die 6 extends out of the die pressing part; the secondary oil cylinder controls the secondary upper die to move, so that the secondary upper die can extend out of the die pressing part and can also be retracted into the die pressing part. Because the die body length of the second-level upper die is less than that of the first-level upper die, the second-level upper die can be completely folded into the first-level upper die, and the working effect of the first-level upper die cannot be influenced.
When the second-level upper die needs to be used, the first-level oil cylinder can be controlled to adjust the position of the second-level upper die to the lower die set, and then the second-level oil cylinder is started to press the second-level upper die to finish the bending operation; when the first-level upper die is required to be used, the telescopic rod of the second-level oil cylinder is operated to contract, so that the second-level upper die is retracted into the first-level upper die and is kept still, and the first-level oil cylinder is operated to drive the first-level upper die to complete pressing.
As shown in fig. 3, a lower die set 4 is slidably arranged on the workbench 1; the lower die set 4 is connected with the workbench through a static pressure guide rail 8; the hydrostatic guideway 8 comprises a connecting block 12 and a pulley 13; the upper end of the connecting block is fixed with the lower module, and the lower end of the connecting block is connected with the pulley; a sliding groove 14 is arranged on the table surface of the workbench; the inner side wall of the chute is provided with a curved surface part 15; the curved surface part is matched with the pulley.
