Description

Technical Field

[0001] This utility model relates to the field of stamping dies, and in particular to a die for producing the front connecting plate of the front longitudinal beam with anti-displacement function. Background Technology

[0002] The front connecting plate at the front longitudinal beam, or simply the front connecting plate, is a metal plate that connects the front end of the front longitudinal beam to other body structures or components. The front connecting plate is typically located at the very front of the front longitudinal beam, connecting to components such as the front bumper beam and radiator support frame, forming a crucial support structure for the front of the vehicle body. Besides its connecting and supporting functions, the front connecting plate also serves a positioning and fixing purpose, ensuring precise assembly of the vehicle body.

[0003] During the production of the front panel, a stamping die is used for processing. After the sheet metal is placed on the die, it is stamped and formed using a stamping block. However, existing front panel stamping dies do not have a structure for clamping and fixing the sheet metal. During the stamping process, the sheet metal may shift, which affects the accuracy of stamping. In some dies that do have a clamping and fixing structure, the clamping and fixing structure cannot be adjusted, resulting in limited flexibility and adaptability. Furthermore, the clamping structure itself does not have a cushioning effect, and sudden impacts to the sheet metal during clamping can easily cause displacement, resulting in mediocre fixing effect. Utility Model Content

[0004] The main purpose of this utility model is to provide a mold for producing the front connecting plate of the front longitudinal beam with anti-displacement function, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A mold for producing a front connecting plate of a front longitudinal beam with anti-displacement function includes a fixed seat and a movable seat. The fixed seat is provided with a mounting seat, and the mounting seat is provided with a lower mold. The lower mold has a cavity. An upper mold is fixed on the movable seat, and a stamping block is connected to the upper mold.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-4 As shown, a mold for producing the front connecting plate of the front longitudinal beam with anti-displacement function includes a fixed base 1 and a movable base 5. The fixed base 1 is provided with a mounting base 2, and the mounting base 2 is provided with a lower mold 3. The lower mold 3 has a cavity 4. An upper mold 6 is fixed on the movable base 5, and a stamping block 7 is connected to the upper mold 6. A movable plate 8 is connected to the upper mold 6 via a lifting rod 10, and a clamping structure 9 is installed on the lower surface of the movable plate 8. A guide post 12 is installed on the fixed base 1, and a guide sleeve 13 is provided on the movable base 5. The upper end of the guide post 12 is located inside the guide sleeve 13. A return spring 11 is sleeved on the lifting rod 10, and the return spring 11 is located between the movable plate 8 and the upper mold 6.

[0020] During the stamping of the front plate, the fixed seat 1 is installed on the stamping machine, and the movable seat 5 is connected to the drive mechanism on the stamping machine. The sheet metal is placed on the lower die 3 on the mounting seat 2. After the drive mechanism is started, the movable seat 5 lowers along with the upper die 6, the stamping block 7, the movable plate 8, and the clamping structure 9. When the clamping structure 9 contacts the sheet metal, the movable seat 5 continues to lower along with the upper die 6 and the stamping block 7. The movable plate 8 rises relative to the upper die 6 through the lifting rod 10 and compresses the return spring 11. At this time, the clamping structure 9 clamps the sheet metal. As the stamping block 7 descends, the stamping block 7 cooperates with the cavity 4 to complete the stamping of the sheet metal. This completes the processing of the front plate. Throughout the processing, the clamping structure 9 has a good clamping force on the sheet metal, so that the sheet metal will not shift and the stamping accuracy is guaranteed.

[0021] According to the above implementation scheme, the clamping structure 9 includes a fixed rod 901, a square hole 902, an end connecting block 903, a bidirectional lead screw 904, a slider 905, a connecting rod 906, an adjusting plate 907, a screw 908, and an elastic clamping assembly 909. The square hole 902 is formed on the fixed rod 901, and the fixed rod 901 is fixed to the movable plate 8. The end connecting block 903 is fixed to the end of the fixed rod 901. The bidirectional lead screw 904 is installed in the square hole 902, and one end of the bidirectional lead screw 904 passes through the end connecting block 903. The end of the bidirectional lead screw 904 is provided with a hexagonal groove. The slider 905 is fixedly connected to the connecting rod 906. Two sliders 905 are located in the square hole 902, and the sliders 905 are threadedly connected to the bidirectional lead screw 904. The adjusting plate 907 is connected to the connecting rod 906 through the screw 908. The elastic clamping assembly 909 is installed on the adjusting plate 907.

[0022] The elastic clamping assembly 909 includes a pressure plate 9091, a limiting block 9092, a movable rod 9093, a buffer spring 9094, and a stop block 9095. The pressure plate 9091 is fixedly connected to the limiting block 9092, the movable rod 9093 is fixedly connected to the stop block 9095, and the movable rod 9093 passes through the adjusting plate 907. The end of the movable rod 9093 is threadedly connected to the pressure plate 9091, and the buffer spring 9094 is sleeved on the movable rod 9093.

[0023] When using the clamping structure 9, after the clamping structure 9 contacts the plate, the pressure plate 9091 in the elastic clamping assembly 909 first contacts the plate. Then the pressure plate 9091 remains stationary, while the adjusting plate 907 descends along the movable rod 9093 and compresses the buffer spring 9094 until the limit block 9092 contacts the adjusting plate 907. Then the movable plate 8 rises relative to the plate, which can ensure that the normal descent of the movable seat 5 and the upper mold 6 is not affected while clamping the plate. When needed, the relative height of the elastic clamping component 909 can be adjusted. To adjust, simply rotate the adjusting plate 907. The adjusting plate 907, along with the screw 908, rotates and rises on the connecting rod 906, thereby raising and lowering the elastic clamping component 909. After adjustment, it can be used again. The horizontal position of the elastic clamping component 909 can also be adjusted. Use a tool to rotate the bidirectional lead screw 904. The bidirectional lead screw 904 rotates on the fixed rod 901 and the end connecting block 903, thereby driving the two sliders 905 to move within the square hole 902, which in turn moves the connecting rod 906, the adjusting plate 907, the screw 908, and the elastic clamping component 909. After movement, it can be used. The structure is simple and the effect is good.

[0024] It should be noted that the clamping structure 9 can clamp and fix the sheet metal, ensuring good stability during subsequent stamping and forming, and preventing displacement. A two-way lead screw 904 is set on the fixing rod 901, which works with the slider 905 to adjust the position of the connecting rod 906, adjusting plate 907 and elastic clamping component 909, improving the flexibility and adaptability of use. The adjusting plate 907 is connected to the connecting rod 906 through the screw 908, which can be finely adjusted in height, further improving the flexibility and adaptability of use. The elastic clamping component 909 plays a buffering role to prevent displacement of the sheet metal caused by sudden impact. A limit block 9092 is set on the pressure plate 9091. When the limit block 9092 contacts the adjusting plate 907, it will not affect the clamping effect.

[0025] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
