[0019] 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.

[0020] The specific technical solution of this utility model is as follows:

[0021] In one specific embodiment, such as Figure 1 and Figure 2As shown, this utility model provides a pressing and forming device for a crushing induction groove of a front longitudinal beam of an automobile, including a base, a positioning mechanism, a pressing mechanism and a hydraulic drive mechanism;

[0022] The base includes a support platform 1;

[0023] The positioning mechanism is located on the top of the support platform 1 and is used to position the front longitudinal beam 100 to be processed.

[0024] The pressing mechanism is located above the support platform 1, and the pressing mechanism includes a pressing plate 2 and a forming pressing block 3. The top of the pressing plate 2 is fixedly connected to the output end 4 of the hydraulic drive mechanism, and the forming pressing block 3 is fixedly connected to the bottom of the pressing plate 2 through a fixing block 5.

[0025] The above solution is as follows: When using the pressing and forming device for the crushing induction groove of the front longitudinal beam of an automobile, the front longitudinal beam 100 to be processed is first positioned by the positioning mechanism, and then the forming block 3 is pressed down by the hydraulic drive mechanism, so that the forming block 3 acts on the front longitudinal beam 100 and forms the crushing induction groove 101 on the front longitudinal beam 100. After completion, the forming block 3 is reset by the hydraulic drive mechanism, and finally the front longitudinal beam 100 that has been processed is removed.

[0026] In another specific embodiment, such as Figure 1 and Figure 3 As shown, the positioning mechanism includes a positioning seat 6, a top positioning plate 7, and a bottom positioning plate 8. The positioning seat 6 is fixedly connected to the rear end of the top of the support platform 1 via a support seat 9, and the front end of the positioning seat 6 extends to form an inner support rod 10 for the front longitudinal beam 100 to be fitted. The top positioning plate 7 is located on the front side of the positioning seat 6 and is fixedly connected to the top of the support platform 1 via a fixing column 11. The bottom of the top positioning plate 7 is provided with a top contour groove. The bottom positioning plate 8 is located on the front side of the support platform 1 and is fixedly connected to the front end of the top of the support platform 1 via a fixing plate 12. The top of the bottom positioning plate 8 is provided with a bottom contour groove.

[0027] The above scheme is adopted: When positioning the front longitudinal beam 100, the front longitudinal beam 100 is fitted onto the inner support rod 10, and the top of the front longitudinal beam 100 is embedded in the top contour groove of the top positioning plate 7, and the bottom of the front longitudinal beam 100 is embedded in the bottom contour groove of the bottom positioning plate 8. Both the top contour groove and the bottom contour groove are V-shaped structures. After positioning, the front longitudinal beam 100 is placed at an inclination between the top positioning plate 7 and the bottom positioning plate 8, so that the forming pressure block 3 corresponds to the corner side of the front longitudinal beam 100, so that the crushing induction groove 101 is formed on the corner side of the front longitudinal beam 100 by the forming pressure block 3.

[0028] In another specific embodiment, such as Figure 3 As shown, the front end of the support base 8 is provided with a limiting baffle 13.

[0029] The above solution is adopted: when the front longitudinal beam 100 is fitted onto the inner support rod 10, the rear end of the front longitudinal beam 100 abuts against the limiting baffle 13 to limit the front longitudinal beam 100.

[0030] In another specific embodiment, such as Figure 1 and Figure 4 As shown, the bottom of the pressure plate 2 is provided with a guide post mounting plate 14, the bottom of the guide post mounting plate 14 is provided with a front guide post 15 and a rear guide post 16, the top positioning plate 7 is provided with a front guide hole corresponding to the front guide post 15, and the support base 9 is provided with a rear guide hole corresponding to the rear guide post 16.

[0031] The above solution is adopted: the movement of the pressure plate 2 is stable and accurate through the action of the guide column and the corresponding guide hole.

[0032] In another specific embodiment, both the guide post mounting plate 14 and the top positioning plate 7 are provided with through holes for the forming block 3 to pass through.

[0033] 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.
