DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] In the embodiment, Figure 2 、 Figure 3 As shown, a one-time preforming mold for a brake pedal arm includes an upper mold plate and a lower mold plate, and also includes:

[0025] An upper flanging die 1 is provided on the upper mold plate, and the upper flanging die 1 is equipped with a power element 2;

[0026] A pressing block 3 is placed on the upper template, and the pressing block 3 is provided with a first through hole 4;

[0027] The upper bending die 5 is arranged on the upper mold plate, and the upper bending die 5 is equipped with a second power element 6. The upper bending die 5 can pass through the first through hole 4;

[0028] A lower flanging die 7 is provided on the lower mold plate, a second through hole 8 is provided at the center of the lower flanging die 7, and the lower flanging die is equipped with a third power element 9;

[0029] The lower bending mold 10 is arranged on the lower template and passes through the No. 2 through hole 8.

[0030] During flanging, the top surfaces of the lower flanging die 7 and the lower bending die 10 are in the same plane. The plate is placed on the top surface of the lower flanging die 7, and then the upper template drives the pressure block 3 to descend and press the plate. Then the No. 1 power element 2 drives the upper flanging die 1 to descend to flanging the two ends of the plate; after flanging is completed, the upper flanging die 1 is reset, the No. 3 power element 9 drives the lower flanging die 7 to descend, and the No. 2 power element 6 drives the upper bending die 5 to descend and cooperate with the lower bending die 10 to bend both sides of the plate, thereby realizing one-time pre-forming of the brake pedal arm. This mold can effectively improve work efficiency.

[0031] In the embodiment, Figure 2 、 Figure 3 As shown, limiting plates 11 are provided on both sides of the lower flanging die 7. The two ends of the plate are limited to ensure the flanging quality.

[0032] In the embodiment, the first power element 2, the second power element 6 and the third power element 9 are all nitrogen springs. Nitrogen springs are small in size, have large and constant elastic force, and ensure stable mold matching.

[0033] In the embodiment, Figure 2 、 Figure 3 As shown, the lower surface of the pressing block 3 is provided with anti-slip grooves 12. After the pressing block presses the plate, it prevents the plate from slipping and ensures the accuracy of flanging and bending.

[0034] In the embodiment, Figure 4 As shown, the upper flanging die 1 is provided with a guide groove 13 on one side close to the pressing block 3, and the side of the pressing block 3 is provided with a guide portion 14 for cooperating with the guide groove 13. The straightness of the upper flanging die 1 is ensured to ensure the quality of the flanging.

[0035] In the embodiment, Figure 2 、 Figure 3 As shown, the No. 1 through hole 4 cooperates with the upper bending die 5, and the No. 2 through hole 8 cooperates with the lower bending die 10. Ensure the straightness of the upper bending die 5 and the lower flanging die 7 when they are lifted and lowered.
