[0038] The punching of the outer water cutting 100 comprises LIP punching and partial cutting of the framework 110, wherein the LIP punching comprises punching a first cut and a second cut at one end of the upper LIP 120, the first cut is close to the end of the outer water cutting 100, and the second cut is a certain distance away from the first cut, the distance is determined according to different vehicle models, and the LIP punching also comprises partial cutting of the lower LIP 130; the partial cutting of the framework 110 needs to be performed after the LIP punching is completed.

[0039] However, the existing punching process cannot be optimized and simplified due to the relatively old design of the punching structure, and therefore the embodiment of the present application provides an optimized outer water cutting punching device.

[0040] As shown in Figures 6 to 11 the outer water cutting punching device comprises a first punching assembly and a second punching assembly, the first punching assembly and the second punching assembly are adjacent, the first punching assembly is used for LIP punching, the second punching assembly is used for partial punching of the framework 110, the first punching assembly and the second punching assembly are both arranged on the same punching equipment, and LIP punching and partial punching of the framework 110 can be realized at one time, thereby effectively improving the production efficiency.

[0041] The first punching assembly comprises a first positioning member 220 and a first punching piece 260, a second punching piece 240 and a third punching piece 250 capable of rebounding, the first positioning member 220 is used for positioning the first inner side groove 101 of the outer water cutting 100, the first punching piece 260 and the second punching piece 240 are used for notch punching of the upper LIP 120 of the outer water cutting 100, and the third punching piece 250 is used for notch punching and cutting of the lower LIP 130 of the outer water cutting 100.

[0043] The LIP positioned on the outer water cutting 100 of the first positioning member 220 is punched by the first punching piece 260, the second punching piece 240 and the third punching piece 250 of the first punching assembly, so that the notch punching of the upper LIP 120 and the cutting of the lower LIP 130 can be completed by one positioning and one clamping operation. The part of the skeleton 110 of the outer water cutting 100 with punched LIP positioned on the second positioning member 330 is punched by the fourth punching piece 340 of the second punching assembly. It should be noted that the first punching assembly and the second punching assembly can be synchronously operated by one clamping, so that the operation process is simplified, the original five processes are integrated into two processes, and the two processes can be synchronously performed by one station and one device, so that the punching efficiency of the outer water cutting 100 is greatly improved, and the problem of inaccurate positioning caused by multiple positioning is avoided.

[0044] Specifically, after the outer water cutting 100 to be punched LIP is placed in the first positioning member 220 and the outer water cutting 100 to be punched skeleton 110 is placed in the second positioning member 330, the punching device is started.
