In the invention, the workpiece 3 is sheared by controlling the punch 13 to move downwards. The bending of the workpiece 3 is realized by controlling the bending block 12 and the lifting block 22 to move downwards after the shearing is completed.
In the invention, the shearing and bending of the workpiece 3 are performed at the same position of the die, so that the forming engineering and time of the workpiece 3 are short, the forming speed is high, and the efficiency is high. In the process of machining and forming the workpiece 3, the workpiece 3 is less in contact with the die, so that the probability of abnormal size of the workpiece 3 is reduced, and the qualification rate of the workpiece 3 is improved.

In this embodiment, the bending block 12 and the lifting block 22 are controlled to simultaneously descend, so that interference caused by the lifting block 22 to the workpiece edge 31 and the descending bending block 12 in the downward bending process is avoided, the bending of the workpiece 3 is affected, and the normal operation of bending the workpiece 3 is ensured.
As an embodiment of the present embodiment, when the bending block 12 and the lifting block 22 are controlled to simultaneously descend, the bending block 12 and the lifting block 22 are further controlled to descend at the same speed.
In the present embodiment, the bending block 12 and the floating block 22 are moved downward at the same speed, and the workpiece 3 is bent, and the bending block 12 and the floating block 22 do not interfere with each other. In addition, the descending speeds of the bending block 12 and the floating block 22 are controlled to be the same, the control method is simple, the control flow is simplified, the time consumption of the bending process is short, and the bending efficiency is high.
As another implementation manner of this embodiment, when the bending block 12 and the lifting block 22 are controlled to simultaneously descend, the descending speed of the lifting block 22 is further controlled to be greater than the descending speed of the bending block 12.
In this embodiment, the descending speed of the buoyancy block 22 is greater than the descending speed of the bending block 12, so that the buoyancy block 22 does not interfere with the bending block 12 in the descending process, and the normal operation of the die is further ensured, and the potential safety hazard is avoided.
As an embodiment of the present invention, after the buoyancy block 22 is controlled to descend to the first safety distance, the bending block 12 is controlled to descend. In this embodiment, after the buoyancy block 22 is controlled to descend for a certain distance, the bending block 12 is controlled to descend, so that the bending block 12 cannot be interfered by the buoyancy block 22 when descending.
As an implementation manner of this embodiment, a maximum downlink distance L of the bending block 12 in the shearing process is preset, and the first safety distance is greater than or equal to the maximum downlink distance L.
In this embodiment, the first safety distance is greater than or equal to the maximum downlink distance L, so that the buoyancy block 22 will not interfere with the preset downlink distance of the bending block 12 at least, and it is ensured that the bending block 12 will not be interfered by the buoyancy block 22 in the downlink process.
As another embodiment of the present invention, after the buoyancy block 22 is controlled to descend to the second safety distance, the bending block 12 and the buoyancy block 22 are controlled to descend together. Preferably, the second safety distance is smaller than the first safety distance.

By reasonably controlling the second safety distance, the invention avoids the situation that the bending block 12 and the floating block 22 move downwards for too long time, and reduces the bending efficiency.

In step S3 of the present embodiment, the lifting block 22 is controlled to move upward until the upper end surface of the lifting block 22 reaches the workpiece edge 31, so that the lifting block 22 has a supporting effect on the workpiece edge 31, and deformation of the workpiece 3 is avoided.
In step S5 of the present embodiment, the lifting block 22 is lifted to a position where the upper end surface of the lifting block 22 is in the same plane as the lower die plate 21, and the lifting pin 5 is lifted by the same distance as the lifting block 22, so that after the bent workpiece 3 is lifted out, deformation is not easily generated due to the supporting action of the lifting pin 5 and the lifting block 22, and displacement of the workpiece 3 is not easily generated when the workpiece 3 is in a horizontal position. In addition, in the present embodiment, the workpiece 3 is ejected, so that the workpiece 3 can be conveniently removed from the mold later.
