Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Embodiment, a negative angle forming cut-out stamping die as shown in fig. 1 to 9 is provided with a product 20, and is characterized in that: an upper die 100 and a lower die 110 are arranged;
the upper die 100 is provided with an upper die seat 4, a nitrogen spring I5 and a nitrogen spring II6 are embedded in the middle of the upper die seat 4, and a bending punch 1 and a cutting punch 7 are arranged below the upper die seat 4; the lower end of the nitrogen spring II6 is connected with a balance block 3; a material pressing plate 9 is arranged below the cutting punch 7;
the lower die 110 is provided with a lower die base 16, two groups of nitrogen springs III14 are arranged in the middle of the lower die base 16, a floating rod 13 is connected above a nitrogen spring III14, a nitrogen spring IV17 is fixedly arranged on the left side of the lower die base 16, a lower backing plate 15 is arranged on the left side above the lower die base 16, a bending lower die 18 is arranged on the lower backing plate 15, the bending lower die 18 is connected with the tail end of the nitrogen spring IV17, and the bending lower die 18 can slide on the lower backing plate 15; the lower die holder 16 is also provided with a cutting female die 11.
A spring fixing seat 41 is fixedly arranged above the upper die base 4, a nitrogen spring I5 is fixed below the inner part of the spring fixing seat 41, an upper backing plate 2 is arranged below the upper die base 4, and a bending punch 1 is fixed below the upper backing plate 2.
A punch clamping plate 8 is arranged below the right side of the upper die holder 4, and the cutting punch 7 is fixed below the punch clamping plate 8.
A pressure plate insert 10 is arranged below the pressure plate 9, and the pressure plate 9 is connected with the tail end of the nitrogen spring I5.
The pressure plate 9 is provided with an opening 92 and a through hole 91, the shaft end of the nitrogen spring II6 can pass through the opening 92 to be connected with the balance block 3, and the cutting punch 7 can be embedded into and pass through the through hole 91.
A lower cushion block 12 is arranged above the right side of the lower die holder 16, and a cutting female die 11 is fixed on the lower cushion block 12; a positioning block 132 is arranged above the middle of the lower die base 16, a sliding groove is arranged in the positioning block 132, and the floating rod 13 can vertically slide on the sliding groove in the positioning block 132.
The upper end of the buoyancy rod 13 is hinged with a connecting shaft 133, and the connecting shaft 133 is hinged with a connecting plate 134.
The stroke length settings of the two sets of nitrogen springs III14 were different, with the right spring being longer than the left spring.
A product chute 19 is arranged at the left side of the lower die base 16, and a product conveyor belt 21 is arranged at the left side of the product chute 19.
The product 20 is composed of two sets of product parts 201, and a material belt 202 is connected between the two sets of product parts 201.
And (3) a die stamping process:
when the punch goes down, the pressing plate 9 presses the product 20 first under the thrust of the nitrogen spring I5, so that the two groups of product pieces 201 are positioned on the cutting die 11 and the connecting plate 134 respectively, and simultaneously the bending lower die 18 compresses the nitrogen spring IV17 under the thrust of the pressing plate 9, and the balance block 3 compresses the floating rod 13 to be parallel.
