Detailed Description

Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

Referring to fig. 2-3, the present invention discloses a stamping die forming structure. As shown in the figure: the device comprises an upper die structure consisting of an upper die holder 1 and a forming male die 4, and a lower die structure consisting of an elastic element 6 (such as a spring), a limiting block 7, a female die plate 8, a lower die holder 9 and a lower die rotary forming female die 11; the upper die structure is positioned above the lower die structure. The forming die 111 has a C-shaped cross section.

A concave template 8 is arranged on the lower die base 9, a groove 81 is arranged on the concave template 8, and a lower die rotary forming concave die 11 with a forming die orifice 111 is arranged in the groove 81; one end of the elastic element 6 is connected with a concave template 8, and the other end is connected with a lower die rotary forming concave die 11; a limiting block 7 is arranged below the lower die rotary forming female die 11;

the lower end of the upper die base 1 is provided with a forming punch 4, and the lower end of the forming punch 4 is provided with a forming ram 41 with a shape corresponding to the forming die opening 111.

Preferably, the upper die structure further comprises an upper backing plate 2 and a top plate 3, and the lower end of the upper die holder 1 is connected with a forming male die 4 through the upper backing plate 2 and the top plate 3 in sequence.

Preferably, a positioning block 10 for positioning the pre-formed member 5 is provided on the upper end surface of the cavity plate 8. Of course, a positioning groove may be formed in the upper end surface of the cavity plate 8.

By adopting the structure, the operation forming process is as follows:

when the die is arranged on the corresponding press equipment, and the press drives the upper die mechanism to move downwards, the forming ram 41 of the forming male die 4 contacts the positioned component 5 (material sheet, namely the product is in a state before forming) to start the forming in the first stage (namely, the first extension part A1, the second extension part A2 and the circular arc-shaped transition part A3 are formed). After the first stage forming is finished, the punch press moves downwards continuously to drive the lower die to rotate the forming die 11 to start to rotate for forming in the second stage (in this stage, the elastic element 6 also starts to elongate and store tensile force, so that the elastic element 11 can reset when the die is opened), when the punch press reaches the lowest point (at this time, the limit is performed through the limit block 7), the die also reaches a closed state, and the forming is finished (at this time, the folded angle a4 between the circular arc-shaped transition portion A3 and the second extension portion a2 is also formed). The press is then raised from the bottom dead centre to the top dead centre in the reverse order, the elastic element 6 pulling back the lower die-forming matrix 11 during the raising process until it is reset, and when the press reaches the top dead centre, a process is ended and the operation is repeated.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. All equivalent changes and modifications made according to the content of the claims of the present invention shall fall within the technical scope of the present invention.
