A fixed plate, the lower fixed plate is fixedly connected with the base plate, a die is arranged above the lower fixed plate, the die is fixedly connected with the lower fixed plate, and a movable mandrel is arranged on the die, The movable mandrel is provided with a mandrel fixing plate, the mandrel fixing plate is movably connected with the lower fixing plate, the lower fixing plate is also provided with a baffle, and the baffle is fixedly connected with the bottom plate , the said baffle is provided with a lower slant wedge, said lower slant wedge is movably connected with the baffle plate, said lower slant wedge is provided with a side punching pin, and said side punching pin connects with the lower slanting pin through the side fixing plate. Angled wedge fixed connection. The bending process is completed by the first pressing plate, the second pressing plate and the concave die, and the punching needle and the side punching needle complete the punching process of the product, which not only ensures the accuracy of the product, but also improves the production efficiency.

As a preference, an inner guide post is provided on the upper fixing plate, and the inner guide post is fixedly connected with the upper fixing plate. The inner guide column plays a guiding role and improves the production accuracy of the mold at the same time.

Preferably, the upper fixing plate is further provided with a limit block, and the limit block is fixedly connected with the upper fixing plate. The limit block acts as a limit to prevent damage to the punching needle.

Preferably, both ends of the lower slant wedge are provided with a lower slant wedging pressing plate, and the lower slanting wedging pressing plate is fixedly connected with the lower fixing plate. The lower inclined wedge is used to prevent the lower inclined wedge from swinging due to too long.

Preferably, rubber blocks are provided on the upper fixing plate, the first pressing plate and the second pressing plate. The rubber block acts as a buffer.

The utility model has the following beneficial effects: the mold completes bending and punching at the same time, which ensures the precision of the product and improves the production efficiency.

Detailed ways

Below in conjunction with specific embodiment, and in conjunction with accompanying drawing, the technical scheme of the utility model is further described:

Embodiment: Bending and punching die (see accompanying drawings 1, 2, 3), including an upper die and a lower die, the upper die includes an upper template 1, and an upper fixing plate 3 is provided below the upper template 1, The upper fixing plate 3 is bolted to the upper template 1, and the upper fixing plate 3 is provided with an upper oblique wedge 4 and a punching needle 2, and the upper oblique wedge 4 and the punching needle 2 are all connected to the upper fixing plate 3. Bolt connection, the first pressing plate 18 and the second pressing plate 19 are provided under the upper fixing plate 3, and the first pressing plate 18 and the second pressing plate 19 are both movably connected with the upper fixing plate 3, and the lower Die comprises base plate 17, and described base plate 17 top is provided with lower fixed plate 16, and described lower fixed plate 16 is connected with base plate 17 bolts, and described lower fixed plate 16 top is provided with die 12, and described die 12 is connected with the lower fixing plate 16 by bolts, the movable mandrel 13 is arranged on the said die 12, the mandrel fixing plate 14 is arranged on the said moving mandrel 13, and the said mandrel fixing plate 14 is fixed with the lower Plate 16 is movably connected, and described lower fixed plate 16 is also provided with baffle plate 7, and described baffle plate 7 is connected with bottom plate 17 bolts, and described baffle plate 7 is provided with lower inclined wedge 6, and described lower The oblique wedge 6 is movably connected with the baffle plate 7, and the lower oblique wedge 6 is provided with a side punching needle 11, and the side punching needle 11 is connected with the lower oblique wedge 6 by bolts through the side fixing plate 5, and the upper fixing The plate 3 is provided with an inner guide column 8, and the inner guide column 8 is connected with the upper fixed plate 3 by bolts, and the upper fixed plate 3 is also provided with a limit block 10, and the described limit block 10 is connected with the upper fixed plate.
