Referring to fig. 1 to 5, a stamping die includes:
The upper die holder 1 and the lower die holder 4 which are connected with each other in a sliding manner, an upper die 3 arranged on the upper die holder 1 and a lower die 5 arranged on the lower die holder 4 are arranged on the upper die holder 1, the upper die holder 1 is transversely connected with a sliding block 2 in a sliding manner, the upper die 3 is movably connected with the upper die holder 1 up and down, an adaptive sliding key 21 and a sliding groove 31 are respectively arranged on the upper die 3 and the sliding block 2, and the lower end of the sliding groove 31 is inclined outwards.
The principle of the utility model is as follows:
Firstly, placing a blank on a lower die 5, and moving an upper die holder 1 downwards until an upper die 3 contacts the upper surface of the blank, referring to fig. 2, wherein a gap exists between the upper die 3 and the lower die 5 for placing the blank, and the die is in a pressing state;
Then, the upper die holder 1 continues to move downwards, the lower die 5 is kept still, the blank is pressed by the upper die 3, the distance between the upper die holder 1 and the upper die 3 is reduced, and the sliding block 2 is extruded by the upper die 3 to translate outwards until the upper surface of the upper die 3 is contacted with the upper die holder 1;
Thereafter, the upper die holder 1, the upper die 3, and the slide 2 are moved downward as a whole, and the lower die holder 4 and the lower die 5 are also moved downward as they are until the dies are closed, referring to fig. 3, in which the dies are in a clamped state.
Finally, the lower die holder 4 and the lower die 5 are reset, the dies are opened, the product can be taken out, and the whole stamping process is completed. The mold open state refers to fig. 1.
As a preferred embodiment, the die further comprises a connecting post 32, the lower end of the connecting post 32 is fixedly connected with the upper die 3, a limiting table 321 is arranged on the upper portion of the connecting post 32, a step 12 is arranged on the upper die holder 1, and the limiting table 321 can be hung on the step 12. The connecting post 32 is used for limiting the mutual distance between the upper die 3 and the upper die holder 1, and when the limiting table 321 is hung on the step 12, the mutual distance between the upper die 3 and the upper die holder 1 is the largest.
As a preferred embodiment, a spring 6 is provided between the step 12 and the stop block 321. The elastic force of the spring 6 can be applied to the blank as the upper die holder 1 moves downward and the distance between it and the upper die 3 gradually decreases.
As a preferred embodiment, the upper die holder 1 includes an upper die plate 11, the upper die plate 11 is provided with a connecting key which is not shown in the drawing and is arranged transversely, and the slide block 2 is provided with a connecting groove 22 which is arranged transversely and is connected with the connecting groove 22 in a sliding manner. The key-slot connection is one of the reliable ways of achieving a mutual sliding between the upper die plate 11 and the slider 2.
As a preferred embodiment, the slide blocks 2 are connected to both the left and right sides of the upper die 3.
As a preferred embodiment, the lower die 5 includes a central lower die 51 and a side lower die 52, the side lower die 52 is fixedly connected with the lower die holder 4, the central lower die 51 is connected with the lower die holder 4 in a sliding manner up and down, the lower die further includes a hydraulic cylinder, the hydraulic cylinder is connected with the central lower die 51 in a transmission manner, and the sliding block 2 can move down to the inner side of the side lower die 52. The side lower die 2 is matched with the sliding block 2, so that a curved surface can be formed.
The foregoing description of the preferred embodiments of the present utility model should not be construed as limiting the scope of the utility model, but rather should be understood to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the utility model as defined by the following description and drawings or any application directly or indirectly to other relevant art(s).
