[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] The specific technical solution of this utility model is as follows:

[0020] In one specific embodiment, such as Figures 1 to 4 As shown, this utility model provides a stamping die for processing the front longitudinal beam of a vehicle engine compartment, including an upper die and a lower die;

[0021] The lower mold includes a base plate 2. A fixed seat 3 is provided at the top rear end of the base plate 2. Two sets of positioning components 4 are provided at the top of the fixed seat 3. Each set of positioning components includes two inner positioning support rods 5. Each inner positioning support rod 5 extends toward the front end of the base plate 2. A pressure plate 7 is fixedly connected to the top of the base plate 2 through a connecting column 6. The pressure plate 7 is located above the inner positioning support rods 5, and a fixed clamping seat 8 is provided at the bottom of the pressure plate 7. The fixed clamping seat 8 is located between the two sets of positioning components 4, and fixed clamping parts are provided on both sides of the fixed clamping seat 8. Two clamping cylinders 10 are fixedly connected to the top of the base plate 2 through a cylinder seat 9. The two sets of positioning components 4 are located between the two clamping cylinders 10. The two clamping cylinders 10 are arranged opposite to each other. A movable clamping block 11 is fixedly connected to the output shaft of each clamping cylinder 10.

[0022] The upper mold includes a stamping plate 12, which is located above the pressure plate 7. The bottom of the stamping plate 12 is provided with two punches 13, which correspond one-to-one with two sets of positioning components 4. The pressure plate 7 is provided with through holes for the punches 13 to pass through.

[0023] The above solution is adopted: When using the stamping die for processing the front longitudinal beam of a vehicle engine compartment, firstly, the two front longitudinal beams 1 to be processed are respectively fitted onto two sets of positioning components 4. Each set of positioning components 4 is configured with two inner positioning support rods 5 to match the internal structure of the front longitudinal beam 1. The two inner positioning support rods 5 are respectively inserted into the holes of the front longitudinal beam 1 to position and internally support the front longitudinal beam 1. The top position of the inner positioning support rod 5 corresponding to the punch 13 has a forming groove 51 that cooperates with the punch 13. After the front longitudinal beam 1 is fitted into place, the pressure plate 7 presses down on the front longitudinal beam 1 to prevent... During processing, the front longitudinal beam 1 moves up and down, affecting the processing quality. Then, the two clamping cylinders 10 are extended and the movable clamping block 11 is moved. The movable clamping block 11 cooperates with the fixed clamping part of the fixed clamping seat 8 to clamp and fix the front longitudinal beam 1. After that, the hydraulic equipment connected to the stamping plate 12 drives the stamping plate 12 to press down, so that the stamping plate 12 drives the punch 13 to pass through the pressure plate 7 and act on the front longitudinal beam 1. The punch 13 cooperates with the forming groove 51 of the inner positioning support rod 5 to form a crushing groove on the front longitudinal beam 1. Finally, the stamping plate 12 and the movable clamping block 11 are driven to reset respectively, and the processed front longitudinal beam 1 is removed from the positioning assembly 4.

[0024] In another specific embodiment, such as Figure 1 As shown, a support plate 14 is provided on the front side of the base plate 2. The support plate 14 is fixedly connected to the base plate 2 through a connecting plate 15, and the support plate 14 is located below the inner positioning support rod 5.

[0025] The above solution is adopted: a support plate 14 is set to support the bottom of the front longitudinal beam 1 to prevent the front longitudinal beam 1 and the inner positioning support rod 5 from being deformed by pressure.

[0026] In another specific embodiment, such as Figure 1 As shown, each group of positioning components 4 is externally fixed with a rear end limiting member 16.

[0027] The above solution is adopted: by setting a rear end limiting component 16 to limit the rear end position of the front longitudinal beam 1, the positioning effect of the front longitudinal beam 1 is improved.

[0028] In another specific embodiment, such as Figure 1 As shown, the bottom of the stamping plate 12 is provided with a stamping limiting post 17, and the top of the base plate 2 is provided with a stop post 18 corresponding to the stamping limiting post 17.

[0029] The above solution is adopted: by setting the stamping limit post 17 and the stop post 18, the downward pressing position of the stamping plate 12 is limited to avoid excessive pressing stroke that could damage the product and the mold.

[0030] In another specific embodiment, such as Figure 1 As shown, a guide structure 19 is provided between the stamping plate 12 and the base plate 2.

[0031] The above solution is adopted: by setting a guide structure 19 to provide precise guidance for the movement of the stamping plate 12, the stability of the mold operation is improved.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
