[0002] With the development of the automobile industry, the rapid progress of society, and the improvement of consumption levels, the frequency of automobiles as consumer goods is getting faster and faster, and the product modeling is becoming more and more complex, which also leads to the need to update the mold structure. The precision requirements of the rotating bevel are getting higher and higher. Usually, the lower mold rotor of the rotating bevel is reset by the movement of the lower cylinder, and the upper mold bevel slider contacts the drive guide plate in advance, and then the core is pressed and the material is pressed. The bevel is formed, and the core stroke is large. In order to ensure the strength of the core, the bevel stroke is reduced as much as possible. The Z-direction stroke of the bevel is smaller than the Z-direction stroke of the core, resulting in the core being pressed first. Due to the shaping here, the pressure source of the core is arranged with strong pressure, resulting in poor stability of the bevel rotor and easy reversal. The plate is staggered during the bevel forming to ensure the stability of the rotor during movement and meet production needs.

[0003] To solve the above problems, patent document with application number 2013203854264 discloses a rotary bevel wedge mechanism in an automobile stamping die, comprising a rotating body, a rotating shaft, a working part, a support pad, a bevel wedge driver, a reset lifter assembly, a fixed seat, a flip-up bevel wedge slider and a fixed seat.

[0017] Figure 1 It is a structural schematic diagram of the rotary wedge structure of the stamping die in an embodiment of the present utility model.

[0018] like Figure 1 As shown, the rotary bevel structure of the stamping die provided by the present invention includes a pressing core 10 and a rotating bevel assembly 20. The rotating bevel assembly 20 can be movably arranged on the pressing core 10. A limiting assembly 30 is provided between the pressing core 10 and the rotating bevel assembly 20. The rotating bevel assembly 20 includes a bevel rotor 21 and a bevel body 22. The bevel rotor 21 can be rotatably arranged on the pressing core 10. The bevel body 22 is arranged on the bevel rotor 21. The limiting assembly 30 can limit the relative movement between the pressing core 10 and the rotating bevel assembly 20 during the sheet metal forming process, balance the pressure between the pressing core 10 and the rotating bevel assembly 20, thereby avoiding the problem of the bevel rotor 21 being reversed due to excessive pressure on the pressing core 10, ensuring the normal movement of the rotary bevel assembly 20, and ensuring the stability of the sheet metal forming process.

[0019] The rotating bevel assembly 20 also includes a driving cylinder 23 and a connecting rod 24. The connecting rod 24 is arranged between the driving cylinder 23 and the bevel rotor 21. The driving cylinder 23 is connected to the bevel rotor 21 through the connecting rod 24. One end of the connecting rod 24 is rotatably connected to the piston rod of the driving cylinder 23 by a hinged manner, and the other end of the connecting rod 24 is rotatably connected to the bevel rotor 21 by a hinged manner, so that the driving cylinder 23 can drive the bevel rotor 21 to rotate.

[0020] The limiting assembly 30 includes a limiting rod 31, one end of which is mounted on the helical wedge rotor 21 and the other end of which abuts the press core 10.
