[0023] The following will be combined with specific embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0024] See Figures 1 to 8As shown, the structure of the present invention is: a stamping progressive die for a front axle support seat of an automobile, comprising an upper die seat 1 and a lower die seat 2, the lower die seat 2 is connected to the upper die seat 1 by a guide column 3, a pad 4 is provided on the lower side of the upper die seat 1, a fixing plate 5 is provided on the lower side of the pad 4, a punching punch 6, a first trimming punch 7, a second trimming punch 8, a first bending punch 9, a blank, a second bending punch 11, and a cutting punch 12 are provided on the fixing plate 5 in sequence according to the feeding direction, a concave template 13 is provided on the lower die seat 2, a bending punch insert 14 is provided on the concave template 13 corresponding to the position of the first bending punch 9, specifically, the material strip is passed through the feeder, and the material strip is sent to the bottom of the punching punch 6 through the feeder, the press drives the upper die seat 1 to descend, the punching punch 6 penetrates the material strip, and punches out a hole at the support seat A on the material strip, and then the press drives the upper die seat 1 to move upward, and the punching punch 6 moves upward together with the upper die seat 1, and then The feeder drives the material strip forward one step, and then the edge at the support seat B is cut off by one side of the first trimming punch 7. Then the feeder drives the material strip forward one step again, and the edges at the support seats C and D are cut off respectively by the other side of the first trimming punch 7 and one side of the second trimming punch 8. Then the material strip advances one step again, and the edge at the support seat E is cut off by the other side of the second trimming punch 8. Then the material strip advances one step, and the first bending punch 9 cooperates with the bending punch insert 14 to fold out the small bend at F. Then the material strip moves forward one step to the empty space, and the empty space is used to avoid interference between the first bending punch 9 and the second bending punch 11. Then the material strip moves forward one step again, and the second bending punch 11 is used to fold out the large bend at the support seat G. At this point, the support seat has been formed. Then the material strip moves forward one step to the bottom of the cutting punch 12, and the blanking is cut off by the cutting punch 12.

[0025] like Figure 2 、 Figure 5 As shown, a unloading screw 15 is slidably provided on the fixed plate 5, one end of the unloading screw 15 is threadedly connected to the unloading plate 10, and a first spring 16 is provided on the unloading screw 15 between the fixed plate 5 and the unloading plate 10. Specifically, under the action of the first spring 16, the unloading plate 10 first contacts the material belt, and as the upper mold descends, the first spring 16 starts to be compressed, and the unloading plate 10 presses the material belt through the elasticity of the first spring 16.

[0026] like Figure 2 、 Figure 3 、 Figure 4 As shown, a side blade 17 is provided on the fixed plate 5 on one side of the punching punch 6, and a stopper 18 cooperating with the side blade 17 is provided on the concave template 13. Specifically, the side blade 17 cuts off a small part of the material edge on one side of the material strip, and the length of the cut material edge is equal to the step distance of the material strip forward, thereby forming a small step on the side of the material strip. The material strip moves forward a step distance, and the stopper 18 clamps the small step to preliminarily position the material strip.

[0027] like Figure 2 、 Figure 4 As shown, guide pins 19 are provided at intervals on the fixed plate 5. Specifically, the guide pins 19 are arranged according to the step intervals. The end of the guide pin 19 is tapered. Each time the guide pin 19 is stamped, it is first inserted into the hole at the support seat A to ensure the position accuracy during the stamping process.

[0028] like Figure 3 、 Figure 6 、 Figure 7 As shown, floating pins 20 are symmetrically spaced on the concave template 13, and a groove 21 is provided on the floating pin 20. A second spring 22 is provided at the bottom of the floating pin 20. Specifically, the material strip passes through the groove 21. When the mold is closed, the unloading plate 10 presses down the floating pin 20, forcing the floating pin 20 to move down. When the mold is opened, the unloading plate 10 rises, and the floating pin 20 moves up under the action of the second spring 22, lifting the material strip so that the material strip can move forward normally, and at the same time plays a guiding role.

[0029] During specific use, the material strip is passed through the feeder, and the material strip is sent to the bottom of the punching punch 6 through the feeder. The press drives the upper die base 1 to descend, and the punching punch 6 penetrates the material strip and punches out a hole at the support seat A on the material strip. Then the press drives the upper die base 1 to move upward, and the punching punch 6 moves upward together with the upper die base 1. Then the feeder drives the material strip forward one step, and then the edge at the support seat B is cut off by the first trimming punch 7. Then the feeder drives the material strip forward one step again, and the edges at the support seats C and D are cut off by the first trimming punch 7 and the second trimming punch 8 respectively. Then the material strip moves forward one step again, and the edge at the support seat E is cut off by the second trimming punch 8. Then the material strip moves forward one step, and the first bending punch 9 cooperates with the bending punch insert 14 to fold out a small bend at F. Then the material strip moves forward one step to the empty space, and the empty space prevents interference between the first bending punch 9 and the second bending punch 11. Then the material strip moves forward one step again, and the second bending punch 11 folds out a large bend at the support seat G. At this point, the support seat has been formed. Then the material strip moves forward one step to the bottom of the cutting punch 12, and the blanking is cut off by the cutting punch 12.

[0030] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
