[0028] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , this embodiment provides a stamping flanging die 100, including an upper die 110 and a lower die 120. The upper die 110 is driven to move towards or away from the lower die 120. A blank holder 113 and a flanging blade block 114 are arranged on the upper die 110. The blank holder 113 is slidably arranged on the upper die 110 along the movement direction of the upper die 110. The flanging blade block 114 is arranged on the side of the blank holder 113. A boss 123 corresponding to the blank holder 113 and a support block 124 corresponding to the flanging blade block 114 are arranged on the lower die 120. The support block 124 is slidably arranged on the lower die 120 along the movement direction of the upper die 110. A chip storage groove 1241 is arranged on the support block 124. The extending direction of the chip storage groove 1241 is consistent with the flanging extending direction of the processed material.

[0029] When using the stamping flanging die 100 provided by the present application, place the trimmed sheet between the upper die 110 and the lower die 120, and drive the upper die 110 to move towards the lower die 120 to clamp the sheet to be flanged through the blank holder 113 and the boss. The flanging blade block 114 and the support block 124 clamp the flanging area of the flanging sheet. Continue to drive the upper die 110 to move towards the lower die 120. The blank holder 113 and the boss clamp the flanging sheet, so as to drive the flanging blade block 114 to continue to move towards the lower die 120 through the upper die 110, and perform a flanging operation on the flanging area of the flanging sheet through the flanging blade block 114 and the support block 124.

[0030] During the process of clamping and flanging by the flanging blade block 114 and the support block 124, the debris at the edge of the flanging sheet will remain in the chip storage groove 1241, avoiding the debris from flowing into the space between the blank holder 113 and the boss, which may cause appearance indentation on the material during the clamping process of the blank holder 113 and the boss.

[0031] When it is necessary to flange both sides of the flanging sheet, flanging blade blocks 114 are arranged on both sides of the blank holder 113, and support blocks 124 are arranged on both sides of the boss, so as to perform a flanging operation on the flanging areas on both sides of the flanging sheet through the flanging blade blocks 114 and the support blocks 124.

[0032] The stamping and flanging die 100 provided by the present application includes an upper die 110 and a lower die 120. The upper die 110 is driven to move towards or away from the lower die 120. A blank holder 113 and a flanging blade block 114 are arranged on the upper die 110. The blank holder 113 is slidably arranged on the upper die 110 along the movement direction of the upper die 110. The flanging blade block 114 is arranged on the side of the blank holder 113. A boss 123 corresponding to the blank holder 113 and a support block 124 corresponding to the flanging blade block 114 are arranged on the lower die 120. The support block 124 is slidably arranged on the lower die 120 along the movement direction of the upper die 110. A chip storage groove 1241 is arranged on the support block 124. The extending direction of the chip storage groove 1241 is consistent with the flanging extending direction of the processed material, so as to store the debris at the edge of the flanging sheet through the chip storage groove 1241, prevent the debris from falling between the blank holder and the boss 123, and improve the qualified rate of part processing.

[0033] In a feasible embodiment of the present application, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the chip storage groove 1241 includes a plurality of them, and the plurality of chip storage grooves 1241 are parallel to each other.

[0034] Specifically, the chip storage groove 1241 is set to be a plurality of them, so that during the clamping and flanging process, the plurality of chip storage grooves 1241 can store more debris. At the same time, during the clamping and flanging process, as the flanging sheet clamped by the flanging blade block 114 and the support block 124 becomes less and less, the debris at the edge of the sheet all flows into the plurality of chip storage grooves 1241, so as to further reduce the probability of the debris being brought between the blank holder 113 and the convex block.

[0035] In a feasible embodiment of the present application, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the upper die 110 has an installation cavity 111, and the blank holder 113 is slidably arranged in the installation cavity 111.

[0036] When using the stamping and flanging die 100 provided by the present application, place the trimmed sheet between the upper die 110 and the lower die 120, drive the upper die 110 to move towards the lower die 120, so as to clamp the sheet to be flanged through the blank holder 113 and the convex block, and the flanging blade block 114 and the support block 124 clamp the flanging area of the flanging sheet. Continue to drive the upper die 110 to move towards the lower die 120. The blank holder 113 and the convex block clamp the flanging sheet, and the blank holder 113 slides towards the upper die 110 in the installation cavity 111, so as to drive the flanging blade block 114 to continue to move towards the lower die 120 through the upper die 110, and perform a flanging operation on the flanging area of the flanging sheet through the flanging blade block 114 and the support block 124.

[0037] In a feasible embodiment of the present application, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a first elastic component 112 is arranged in the installation cavity 111, and the upper die 110 and the blank holder 113 are connected by the first elastic component 112.

[0038] When using the stamping and flanging die 100 provided by the present application, place the trimmed sheet between the upper die 110 and the lower die 120, drive the upper die 110 to move towards the lower die 120, so as to clamp the sheet to be flanged through the blank holder 113 and the convex block, and the flanging knife block 114 and the supporting block 124 clamp the flanging area of the flanged sheet. Continue to drive the upper die 110 to move towards the lower die 120, the blank holder 113 and the convex block clamp the flanged sheet, and the blank holder 113 slides towards the upper die 110 in the installation cavity 111. At this time, the first elastic component 112 in the first installation cavity 111 accumulates elastic potential energy, and the elastic potential energy accumulated by the first elastic component 112 provides pressure on the blank holder 113, so that the blank holder 113 and the convex block can stably clamp the flanged sheet, so as to drive the flanging knife block 114 to continue to move towards the lower die 120 through the upper die 110, so as to perform a flanging operation on the flanging area of the flanged sheet through the flanging knife block 114 and the supporting block 124.

Continue to drive the upper die 110 to move towards the lower die 120. The pressure member 113 and the convex block clamp the flanging sheet, and the pressure member 113 slides towards the upper die 110 in the installation cavity 111, so as to drive the flanging blade block 114 to continue to move towards the lower die 120 through the upper die 110. The supporting block 124 slides away from the upper die 110 in the accommodating cavity 121 under the pressure transmitted by the flanging tool, so as to perform a flanging operation on the flanging area of the flanging sheet through the flanging blade block 114 and the supporting block 124.

[0043] In a feasible embodiment of the present application, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a second elastic component 122 is arranged in the accommodating cavity 121, and the lower die 120 is connected to the supporting block 124 through the second elastic component 122.

The pressure member 113 and the convex block clamp the flanging sheet, and the pressure member 113 slides towards the upper die 110 in the installation cavity 111. At this time, the first elastic component 112 in the first installation cavity 111 accumulates elastic potential energy. The elastic potential energy accumulated by the first elastic component 112 provides pressure for the pressure member 113, so that the pressure member 113 and the convex block can stably clamp the flanging sheet, so as to drive the flanging blade block 114 to continue to move towards the lower die 120 through the upper die 110. The supporting block 124 slides away from the upper die 110 in the accommodating cavity 121 under the pressure transmitted by the flanging tool. The second elastic component 122 in the accommodating cavity 121 accumulates elastic potential energy. The elastic potential energy accumulated by the second elastic component 122 provides a supporting force for the supporting block 124, so that the flanging blade block 114 and the supporting block 124 clamp the flanging area of the flanging sheet, so as to perform a flanging operation on the flanging area of the flanging sheet through the flanging blade block 114 and the supporting block 124.
