Preferably, the upper die plate 100 is provided with a first material pressing block 200, a first driving block 300 and a second driving block 400, and the upper die plate 100 can drive the first material pressing block 200, the first driving block 300 and the second driving block 400 to move when ascending and descending.

A lower die plate 500 located below the upper die plate 100, the lower die plate 500 being provided with a placing seat 510 for placing the workpiece 900, the placing seat 510 being located right below the first swaging block 200, and the first swaging block 200 may cooperate with the placing seat 510 to swage the workpiece 900.

Preferably, a placing seat 510 is disposed on one side of the lower mold plate 500, and the placing seat 510 is adapted to a part of the surface of the workpiece 900, so that the workpiece 900 can be placed on the placing seat 510 first, and when the upper mold plate 100 is lowered to a certain position, the first swaging block 200 can press the workpiece 900, so that the workpiece 900 is fixed between the first swaging block 200 and the placing seat 510.

A slider 600 slidably connected to the lower template 500, wherein the first driving block 300 can drive the slider 600 to move towards the placing seat 510; preferably, the slider 600 is positioned at the other side of the lower mold plate 500 so that the slider 600 can slide toward the placing seat 510.

It is worth to be noted here that multiple L-shaped notches need to be punched in the sunroof rail of the automobile to match the installation of the roof and the sunroof rail, so the size accuracy of the L-shaped notch of the sunroof rail is of the utmost importance; in addition, the L-shaped notch can be punched for multiple times, but a small offset (namely a step) is generated at the connecting position of the two cutters after multiple times of punching, so that the product rejection rate is extremely high.

In the embodiment, the L-shaped notch is directly punched out by one step, so that no break difference (step) exists, the precision and the qualification rate of the product can be greatly improved, and the problem that the quality of the L-shaped notch punching of the product is greatly improved due to the break difference (step) after multiple times of punching is effectively solved.

In addition, the mechanism is very compact and ingenious, and the occupied space and the positioning adjusting time are greatly reduced.

When the upper die plate 100 descends until the first swaging block 200 presses the workpiece 900, the upper die plate 100 can continue to descend and drive the second driving block 400 to drive the second swaging block 700 to act.

Preferably, when the upper die plate 100 descends to a certain position, the first material pressing block 200 first contacts with the workpiece 900, and when the upper die plate 100 continues to descend, the first material pressing block 200 remains stationary, the first elastic member 110 compresses, so that the upper die plate 100 can continue to descend, and as the upper die plate 100 descends to a lower position, the second driving block 400 contacts with the second material pressing block 700, at this time, the second elastic member 120 compresses, so that the upper die plate 100 can also continue to descend and finally the first driving block 300 drives the cutter block 800 to move.

Because the first elastic piece 110 is connected with the first swaging block 200, and the second elastic piece 120 is connected with the second driving block 400, the first swaging block 200 does not prevent the upper die plate 100 from continuously descending under the condition of pressing the workpiece 900, and similarly, the upper die plate 100 can not be prevented from continuously descending when the second driving block 400 presses the second swaging plate, so that the action of the upper die plate 100 is not hindered by the static state of the first swaging block 200 and the second driving block 400, and the whole swaging and punching process can be smoothly carried out.
