Embodiment 1
[0027] Embodiment 1: A stamping process for a seat seat plate, such as figure 2 , the flat steel plate 8 to be stamped is stamped once to form the upper planar portion 21 , the lower planar portion 22 , and the tensile transition portion 23 .
[0028] The upper plane portion 21 is higher than the lower plane portion 22, and the upper plane portion 21 includes an upper plane one 211, a first slope 212, an upper plane two 213, an arched surface 214, a second slope 215, and an upper plane one 211 connected in sequence. 213 higher than the upper plane. The first slope 212 is inclined, one end of the first slope 212 is connected with the upper plane one 211, the other end is connected with the upper plane two 213, the middle of the arched surface 214 is arched, and the two ends of the arched surface 214 are connected with the upper plane two respectively. 213 is connected with the second slope 215 , and the second slope 215 arcs downward from the end connected with the arched sur...
Embodiment 2
[0040] Embodiment 2: the stamping die that is installed in the stamping process of the seat seat plate, such as image 3 , comprising a support 41, a column 42 fixed above the support 41, a bottom plate 43 fixed on the column 42, a bottom mold 5 fixed on the bottom plate 43, a lower mold 5 fixed above the bottom plate 43, and a first hydraulic cylinder fixed on the top of the bottom plate 43 71. The mounting plate 44 fixed to the piston rod of the first hydraulic cylinder 71, the upper die 6 fixed on the mounting plate 44 and located above the lower die 5.
[0041] The columns 42 are arranged in two rows, and the second hydraulic cylinder 72 is arranged in the middle of the columns 42 of the two rows. The support 41 and the column 42 are fixed by the first bolt 74 , the first bolt 74 is a counterbore bolt, and the first bolt 74 passes through the support 41 and extends into the column 42 to be threadedly connected with the column 42 . The first hydraulic cylinder 71 is arranged...
