A lower die 5 is arranged in the installation groove. A workpiece body is placed on the upper end surface of the lower die 5. A limiting groove is opened at the center of the lower die 5. A lifting assembly 6 is arranged in the limiting groove. By setting the lifting assembly 6, the contact between the inclined surface of the sliding groove 602 and the connecting rod 604 can be utilized. When the connecting rod 604 moves, the lifting plate 601 can be driven to move up and down at the same time, so as to lift the workpiece body after stamping, thereby reducing the operation time for manually separating the workpiece body from the lower die 5 and providing convenience for the staff to take the workpiece after stamping.

[0026] The lifting assembly 6 includes a lifting plate 601 slidably connected to the inner wall of the limiting groove. A sliding groove 602 is opened on the side surface of the lifting plate 601.

The locking grooves 603 include an arc portion 6031 and a connecting portion 6032. The connecting portion 6032 is parallel to the lifting plate 601 and communicates with the sliding groove 602. A connecting rod 604 is slidably connected in the sliding groove 602. Both ends of the connecting rod 604 are fixedly connected with connecting seats. The surface of the connecting seat is fixedly connected with a push rod 605. The surface of the push rod 605 is also slidably connected in the stamping table 1. By setting the locking grooves 603, when the push rod 605 moves the connecting rod 604 to the locking grooves 603, the arc surface of the arc portion 6031 can be used to fit the surface of the connecting rod 604, and the connecting rod 604 can be placed on the connecting portion 6032 for buffering and self-locking. When lifting the workpiece body, by locking the position of the connecting rod 604, the stability of the position after lifting can be improved, the workpiece body can be prevented from being knocked, and the taking efficiency of the workpiece body can be improved.

[0027] In an embodiment of the present utility model, guiding assemblies 7 are arranged on both symmetric sides of the lower end surface of the connecting plate 3. The overall position of the guiding assemblies 7 is closer to the lower die 5 than the upper die 4.

[0028] The guiding component 7 includes fixing rods 701 symmetrically fixed to the lower end face of the connecting plate 3. The lower end face of the fixing rod 701 is fixedly connected with a fixing plate. The lower end face of the fixing plate is fixedly connected with a spring 702. The lower end face of the spring 702 is fixedly connected with a guiding plate 703. A plurality of rotating rollers 704 are arranged at equal intervals and movably on the lower end face of the guiding plate 703. The surface of the rotating roller 704 is arranged movably with the upper surface of the workpiece body. The lower end face of the fixing rod 701 is also fixedly provided with a triangular protrusion 705. The inclined surface of the triangular protrusion 705 is arranged on the opposite side of the rotating roller 704. By arranging the guiding component 7, the elasticity of the spring 702 can be utilized. When the hydraulic cylinder 8 stretches downward, the rotating roller 704 and the triangular protrusion 705 can first come into contact with the surface of the workpiece body. The inclined surfaces of the triangular protrusion 705 can be respectively in contact with both sides of the workpiece body, so as to limit and adjust the position of the workpiece body, enabling the workpiece body to be adjusted to the center of the lower die 5, thereby reducing the time for manual alignment operation of the workpiece body, improving the stamping efficiency and accuracy. Subsequently, the surface of the rotating roller 704 is used to come into contact with the workpiece body, which can fix the workpiece body before stamping, and after stamping, the rotation of the rotating roller 704 can be utilized. When the workpiece body contracts and deforms under stamping, the rotating roller 704 rotates along with the deformation direction, so as to realize the surface pressing of the workpiece body while avoiding hindrance to its deformation and contraction, improving the fluency and stability of stamping.

[0029] Working principle: This embodiment provides a forming die for an automotive cover plate. When in use, first place the workpiece body on the upper surface of the lower die 5. Subsequently, utilize the stretching movement of the hydraulic cylinder 8 to drive the guiding assembly 7 and the upper die 4 to move downward simultaneously. At this time, the triangular protrusion 705 and the rotating roller 704 first come into contact with the side and surface of the workpiece body. At this time, by using the inclined surface of the triangular protrusion 705, its position can be guided and limited when coming into contact with the workpiece body, so that the position of the workpiece body can be adjusted to the center of the surface of the lower die 5. At this time, use the rotating roller 704 to contact the surface of the workpiece body, and under the continuous stretching state of the hydraulic cylinder 8, squeeze the spring 702, so that the rotating roller 704 abuts against the workpiece body, making the position of the workpiece body fixed when being stamped. And when the workpiece deforms and contracts towards the center of the lower die 5 when being stamped, the rotating roller 704 can rotate following the contraction of the workpiece body. When it is necessary to take the workpiece body after stamping is completed, the push rod 605 can be pulled first, thereby driving the connecting rod 604 to move parallel in the direction of the push rod 605. During the movement, through the limitation of the chute 602, the lifting plate 601 can be driven to move upward to eject the workpiece body. Subsequently, when the connecting rod 604 moves to the connecting part 6032, its surface fits with the inner wall of the arc part 6031, thereby locking the lifting plate 601 after it reaches the maximum lift. Then the workpiece body can be taken directly.
