Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Examples
As shown in fig. 1 to 4, the convex hull punching and shaping die of the present embodiment includes a mechanism base 10, a punching and shaping insert 30, and a pre-punching punch 70, wherein an automobile roof 90 is placed on the top of the mechanism base 10, a fixed mold 80 for clamping and limiting the position of the automobile roof 90 is arranged above the mechanism base 10, the pre-punching punch 70 for punching a hole is arranged on the fixed mold 80, the punching and shaping insert 30 capable of moving up and down is arranged in the mechanism base 10, and the pre-punching punch 70 moves down to punch a hole while the punching and shaping insert 30 moves up.
A guide sleeve 20 is arranged on one side inside the mechanism seat 10, a punching and shaping insert 30 is connected to the guide sleeve 20 in a sliding mode, and a driving mechanism for driving the punching and shaping insert 30 to move up and down is arranged inside the mechanism seat 10.
The driving mechanism comprises a driving trolley 40, a trolley return nitrogen cylinder 50 and a driver 60, wherein the driving trolley 40 is arranged inside the mechanism seat 10, one side of the driving trolley 40 is connected with the bottom end of the punching and shaping insert 30, the other side of the driving trolley 40 is connected with the driver 60, the driver 60 is arranged inside the mechanism seat 10, and the trolley return nitrogen cylinder 50 connected with the middle position of the driving trolley 40 is arranged inside the mechanism seat 10.
