further, the action 211 drives the moving plate 212 to move downwards, as shown in fig. 3 to 4, the action 211 drives the moving plate 212 to move upwards and downwards, so as to drive the first fixed connecting plate 225, the third fixed connecting plate 33 and the fourth driving member 232 to move upwards and downwards, so that the thimble 2232 in indirect connection with the first fixed connecting plate 225, the trimming member 32 in indirect connection with the third fixed connecting plate 33 and the third cam 231 in connection with the fourth driving member 232 move towards the direction close to the workpiece, and then the fourth driving member 232 drives the third cam 231 to move towards the direction close to the workpiece, so that the third cam 231 and the first cam 1211 in the fixed assembly 23 achieve the effect of clamping the workpiece, and the position to be bent of the workpiece can be kept unchanged;

the next action is that second driving element 222 in bending assembly 22 drives pin 2332 to move in a direction close to the workpiece, so that pin 2332 extends out of clearance 226 side of first connecting element 224, and then first driving portion 2212 drives pin 2332 to move in a direction close to the workpiece through first connecting element 224 and second driving element 222, so that pin 2232 moves towards notch 124 formed by first cam 1211 and second cam 1212, in order to ensure that the product is not broken, pin 2232 and notch 124 reserve a certain tracking clearance, which is the thickness of the workpiece, where the angle of notch 124 is set slightly downward due to the fact that first driving portion 2212 drives pin 2332 to move in a direction close to the workpiece through first connecting element 224 and second driving element 222, so that the cylindrical side of pin 2232 moves towards notch 124 to bend the workpiece, and due to the elasticity of the workpiece, there is a rebound after bending, the actual bending angle is more than the standard bending angle, and the bending shape is related to the formed profiling clearance;

in actual production, as shown in fig. 11, a transition state as shown in the middle workpiece of fig. 11 is often formed, and therefore, the next action is to drive the trimming member 32 to move toward the workpiece by the fifth driving member 31 in the trimming mechanism 3, so as to flatten the corner and form the shape shown on the right side of fig. 11.

Finally, when the acting force of the acting element 211 and the driving elements is removed, the positioning mechanism 1, the bending mechanism 2 and the trimming mechanism 3 are restored to the original positions, the workpiece is still placed at the first contour 1211 at this time, the first contour 1211 tends to be transformed to the initial state due to the resilience force of the elastic element 123 in the positioning mechanism 1, and the first contour 1211 can surround a certain angle relative to the fixed element 122, so that the first contour 1211 has a certain corrective effect on the bent position of the workpiece at the notch 124.

The above is only the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all of which are in the utility model discloses a conceive, utilize the equivalent structure transform that the content of the specification and the attached drawings did, or directly/indirectly use all to include in other relevant technical fields the patent protection scope of the present invention.
