DETAILED DESCRIPTION

[0021] The following is a further detailed description of the specific implementation methods of the present invention through the description of the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0022] Figure 1 It is a structural schematic diagram of the active shaping and pressure regulating structure of the stamping die in the embodiment of the present utility model.

[0023] like Figure 1 As shown, the stamping die movable shaping and pressure regulating structure provided by the utility model includes a base 10, a pressure regulating assembly 20, a floating pressure core 30 and a turning insert 40. The pressure regulating assembly 10 is movably arranged on the base 10, and the floating pressure core 30 and the turning insert 40 are movably arranged on the pressure regulating assembly 20. The pressure regulating assembly 20 can drive the floating pressure core 30 and the turning insert 40 to move together, or drive the floating pressure core 30 to move alone, so as to control the pressure. The pressure is adjusted according to whether the side charging port of the car needs to be turned, which can avoid the car side panel being pressed and deformed, and can ensure the stamping quality of the car side panel. The stamping die movable shaping and pressure regulating structure provided by the utility model can adjust the stamping pressure according to whether the side charging port of the car needs to be turned, which avoids the car side panel being pressed and deformed when turning is not required, and ensures the stamping quality of the car side panel when turning is required.

[0024] Figure 2 It is a structural schematic diagram of the voltage regulating assembly in an embodiment of the present utility model.

[0025] like Figure 2 As shown, the pressure regulating assembly 20 includes a movable slider 21, a first lifting cylinder 22 and a second lifting cylinder 23. The movable slider 21 is movably arranged on the base 10. The first lifting cylinder 22 is connected to the movable slider 21. The second lifting cylinder 22 is arranged on the movable slider 21 and connected to the floating pressure core 30. The first lifting cylinder 22 can drive the movable slider 21 to move up and down, and the second lifting cylinder 23 can drive the floating pressure core 30 to move up and down, so that the floating pressure core 30 can be lifted and lowered.

[0026] A guide column 11 is provided on the base 10, and a guide hole adapted to the guide column 11 is provided on the movable slider 21. The guide column 11 can be movably inserted into the guide hole, thereby guiding the lifting movement of the movable slider 21, ensuring that the first lifting cylinder 22 can smoothly drive the movable slider 23 to lift and lower.

[0027] Figure 3 It is a structural schematic diagram of the floating pressure core in an embodiment of the present utility model.

[0028] like Figure 3 As shown, the floating pressure core 30 is provided with a limiting groove 31, and the movable slider 21 is provided with a limiting plate 211 that matches the limiting groove 31. The limiting plate 2111 is locked in the limiting groove 31. The limiting grooves 31 are evenly distributed on the sides of the floating pressure core 30. The limiting grooves 31 and the limiting plates 211 can limit the lifting and lowering movement of the floating pressure core 30. This allows the floating pressure core 30 to be raised and lowered by the second lifting cylinder 23 alone, or by the first lifting cylinder 23 driving the movable slider 21 to move the floating pressure core 30, thereby adjusting the pressure according to whether the vehicle side charging port needs to be adjusted.

[0029] The turning insert 40 is arranged on the movable slider 21, and a turning groove 32 is opened on the floating pressure core 30. The turning insert 40 is located in the turning groove 32. When the first jacking cylinder 22 is working and the second jacking cylinder 23 is not working, the first jacking cylinder 22 drives the movable slider 21 to rise, and the movable slider 21 drives the floating pressure core 30 and the turning insert 40 to rise together; when the first jacking cylinder 22 is not working and the second jacking cylinder 23 is working, the second jacking cylinder 23 drives the floating pressure core 30 to rise alone, thereby adjusting the pressure according to whether the charging port of the car side needs to be turned. When the charging port needs to be flipped, the first lifting cylinder 22 works and the second lifting cylinder 23 does not work. The floating pressure core 30 and the flipping insert 40 rise together and press against the stamping upper die to complete the processing of the car side panel, ensuring the stamping quality of the car side panel when flipping is required; when the charging port of the car side panel needs to be flipped, the first lifting cylinder 22 does not work and the second lifting cylinder 23 works. The floating pressure core 30 rises alone under the drive of the second lifting cylinder 23 and presses against the stamping upper die to complete the processing of the car side panel, avoiding the compression deformation of the car side panel when flipping is not required.

[0030] A guide plate 41 is provided on the flipping insert 40, and a guide groove adapted to the guide plate 41 is provided on the floating pressure core 30. The guide plate 41 can be movably arranged in the guide groove, which can prevent the flipping insert 40 from shaking when the floating pressure core 30 and the flipping insert 40 rise together, thereby further improving the stamping quality of the automobile side panel.

[0031] The first lifting cylinder 22 is an air cylinder, and the second lifting cylinder 23 is a nitrogen cylinder, so that the pressure of the first lifting cylinder 22 is greater than the pressure of the second lifting cylinder 23, ensuring that the pressure of the first lifting cylinder 22 is large enough when turnover is required, ensuring the stamping quality of the automobile side panel, and avoiding the second lifting cylinder 23 being too large when turnover is not required, resulting in compression deformation of the automobile side panel.
