[0012] Compared with the prior art, the beneficial effects of this utility model are: 1.

Driven by the cylinder, the clamping plate opens and closes through the cooperation of the inclined rod and the rotating seat, thus clamping or releasing the materials placed on the plate. The contact surface on the clamping plate increases the contact area with the materials, improving clamping stability. At the same time, the cooperation of the displacement block and the slide rail allows the clamping plate to move smoothly during clamping, further ensuring clamping accuracy.

[0013] 2. The set-up die-pressing mechanism enables the equipment to automatically perform stamping operations on materials, improving production efficiency. Driven by the motor, the rotating rod drives the rotating ring to rotate, which in turn pushes the stamping plate to move up and down reciprocally through the swing rod and hinge seat. The stamping seat at the lower end of the stamping plate cooperates with the mounting plate to realize the stamping operation on the material. The cooperation between the slider and the slide groove ensures the stability of the stamping plate during the stamping process, avoiding deviation and shaking, thereby improving the stamping accuracy and efficiency. At the same time, the transmission connection between the motor and the rotating rod enables the die-pressing mechanism to work continuously and stably, meeting the needs of continuous and efficient production in the cold heading process.

[0019] Working principle: First, the cylinder 41 drives the clamping plate 42 to clamp the workpiece. The contact surface 45 at one end of the clamping plate 42 contacts the workpiece. Through the combined action of the three clamping plates 42, the workpiece is stably clamped. At the same time, the opening 43 at the bottom of the clamping plate 42 allows the inclined rod 44 to rotate flexibly within the opening 43. In conjunction with the rotating seat 46, the clamping plate 42 can adapt to workpieces of different shapes and sizes during the clamping process, improving the flexibility and adaptability of clamping. After clamping is completed, the motor 51 starts and outputs power through the output shaft. The rotating rod 52 is driven to rotate, and the rotating rings 53 on both sides of the rotating rod 52 rotate accordingly, which in turn drives the swing rod 54 to swing. The hinge seat 55 at the lower end of the swing rod 54 pushes the stamping plate 56 to move downward. The stamping seat 58 at the lower end of the stamping plate 56 performs cold heading on the workpiece. The sliders 59 fixed on both sides of the stamping plate 56 slide in the slide groove 6 to ensure the stability and accuracy of the stamping plate 56 during the movement. Through the clamping mechanism 4 and the die-forming mechanism 5, this device can realize automatic centering and clamping of the workpiece and cold heading, thereby improving processing efficiency and accuracy. Then, during the cold heading process, the stamping seat 58 applies pressure to the workpiece, causing it to undergo plastic deformation to achieve the required shape and size. Simultaneously, since the stamping plate 56 has sliders 59 fixed to both sides and slides stably within the groove 6, this arrangement not only ensures the stability of the stamping plate 56 during movement but also improves processing accuracy. Furthermore, the cooperation between the groove 6 and the sliders 59 allows the stamping plate 56 to move smoothly up and down, avoiding processing errors caused by friction or jamming. When processing workpieces of different shapes or sizes, the clamping mechanism 4 or related components of the die-casting mechanism 5 can be easily replaced to adapt to new processing requirements. Through a reasonable structural design and the coordinated use of components, automatic centering and clamping of the workpiece and cold heading are achieved, improving processing efficiency and accuracy while reducing production costs. The above describes the entire working process of the device. Any content not described in detail in this specification belongs to existing technology known to those skilled in the art.
