[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 Figure 1 and Figure 2 As shown, this utility model provides a collapsible structure forming tooling, including a tooling base plate 1, a positioning mechanism and a stamping mechanism;
[0021] The positioning mechanism includes a limiting seat 2, an inner positioning component 3, and an outer positioning component 4. The limiting seat 2 is located at the top of the rear end of the tooling base plate 1. The inner positioning component 3 is a rod-shaped component, and its rear end is fixedly connected to the front side of the limiting seat 2. The outer positioning component 4 is a plate-shaped component, and its bottom is provided with a positioning groove 41. The outer positioning component 4 is located above the inner positioning component 3, and its outer positioning component 4 is fixedly connected to the top of the tooling base plate 1 through a connecting column 5.
[0022] The stamping mechanism includes a stamping plate 6 and a forming punch 7. The stamping plate 6 is disposed above the outer positioning member 4 and is driven by a press. The top end of the forming punch 7 is fixedly connected to the bottom end of the stamping plate 6.
[0023] The above solution is adopted: When using the collapsible structure forming fixture of this utility model, the worker puts the automobile longitudinal beam 100 to be processed on the inner positioning part 3 until the rear end of the automobile longitudinal beam 100 abuts against the limiting seat 2, and the corner side of the automobile longitudinal beam 100 is inserted into the positioning groove 41 at the bottom of the outer positioning part 4, thereby realizing the rapid positioning of the automobile longitudinal beam 100; then the press is controlled to drive the stamping plate 6 to press down, so that the forming punch 7 passes through the through hole on the outer positioning part 4 and stamps the automobile longitudinal beam 100 to form the collapsible structure 101. After completion, the press is controlled to drive the stamping plate 6 to reset, and the worker removes the processed automobile longitudinal beam 100 from the inner positioning part 3.
[0024] In another specific embodiment, such as Figure 1 As shown, a support block 8 is provided below the front end of the inner positioning component 3, and a slide rail 9 is provided at the top front end of the tooling base plate 1. The bottom of the support block 8 is slidably engaged with the slide rail 9, and a cylinder 10 is connected to the side of the support block 9. The cylinder 10 is fixedly connected to the tooling base plate 1 through a bracket 11.
[0025] The above solution is as follows: After the worker places the automotive longitudinal beam 100 to be processed onto the inner positioning component 3, the control cylinder 10 extends and drives the support block 8 to move to below the front end of the inner positioning component 3. The support block 8 supports the front end of the inner positioning component 3 to prevent deformation due to pressure. After the automotive longitudinal beam 100 is processed, the control cylinder 10 retracts and drives the support block 8 to move away, so that the worker can remove the automotive longitudinal beam 100 from the inner positioning component 3.

[0027] The above solution facilitates the disassembly and assembly of the inner positioning component 3, enabling its replacement.
[0028] In another specific embodiment, such as Figure 1 and Figure 2 As shown, a guide plate 13 is fixedly connected to the bottom of the stamping plate 6, and a guide post 14 is fixedly connected to the bottom of the guide plate 13. The outer positioning member 4 is provided with a guide hole corresponding to the guide post 14.
[0029] The above solution is adopted: the guide post 14 cooperates with the guide hole to guide the stable movement of the stamping plate 6.

[0031] The above solution is adopted: the cutting edge and the groove 31 are used to stamp the automobile longitudinal beam 100 to form a collapsible structure 101.
