[0031] See also Figure 1-Figure 7 , the utility model provides the following technical solutions.

[0032] Example 1: In order to solve the problem of inconvenience in feeding materials in the prior art, this embodiment adopts the following technical solution: a multi-station cold heading machine cold heading device for fastener processing is provided with a base 1, a fixed plate 3, a servo motor 4, a screw 5, a movable plate 6 and a feeding mechanism 7. A through hole 2 is provided at the upper left end of the base 1, and the opening size of the through hole 2 is not less than the opening size of the punching slot 9. The front side of the upper end of the base 1 is fixedly connected to the fixed plate 3, and the right end of the fixed plate 3 is fixedly installed with a servo motor 4. The output end of the servo motor 4 is fixedly connected to the screw 5, and the servo motor 4 drives The screw rod 5 rotates in the middle of the fixed plate 3, and the screw rod 5 is threadedly connected to the movable plate 6 for connection. The feeding mechanism 7 includes a multi-station mold 8 fitted in the middle of the upper end of the base 1, a plurality of punching grooves 9 arranged at equal intervals on the multi-station mold 8, a side plate 10 arranged at the rear end of the multi-station mold 8 and a movable block 11 fixedly connected to the middle of the rear end of the multi-station mold 8. The movable plate 6 is fixedly connected to the front end of the multi-station mold 8, and the movable plate 6 drives the multi-station mold 8 to move left and right at the upper end of the base 1. The multi-station mold 8 drives the movable block 11 to form a left and right sliding structure with the side plate 10, as shown in FIG. Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, the stamping grooves 9 are opened at equal intervals on the multi-station mold 8. The multi-station mold 8 moves to the rightmost state, and the material to be processed is placed in the stamping groove 9. Then the servo motor 4 installed at the right end of the fixed plate 3 is started. The servo motor 4 drives the screw rod 5 to rotate in the middle of the fixed plate 3. At this time, the screw rod 5 drives the multi-station mold 8 to move to the left through the movable plate 6. The multi-station mold 8 drives the movable block 11 to slide between the side plate 10, thereby improving the stability of the multi-station mold 8 moving on the upper end of the base 1, thereby facilitating the automatic transportation and loading of the material.

[0033] Example 2: The existing multi-station cold heading machine cold heading device for fastener processing lacks a limiting mechanism to limit the punch head 16 during the punching process, so it is easy to deviate during long-term use. Therefore, a fixed bracket 12, an electric telescopic rod 13, a movable push plate 14, a vertical rod 15 and a punch head 16 are set. The upper end of the base 1 is fixedly connected to the fixed bracket 12, and the upper end of the fixed bracket 12 is fixedly installed with an electric telescopic rod 13 for driving, and the output end of the electric telescopic rod 13 is fixedly connected to the movable push plate 14, and the middle part of the lower end of the movable push plate 14 is fixedly connected to the punch head 16. The inner side walls of the front and rear ends of the fixed bracket 12 are fixedly connected to the vertical rod 15, as shown in FIG. Figure 1 、 Figure 2 and Figure 7 As shown, when the material to be processed moves to the bottom of the punching head 16, the central processing unit controls to turn off the servo motor 4 and start the electric telescopic rod 13 at the same time. The electric telescopic rod 13 drives the movable push plate 14 to move downward, so that the movable push plate 14 drives the punching head 16 to move downward, and the punching head 16 punches the material in the punching groove 9. In addition, the movable push plate 14 slides between the vertical rod 15 during the up and down movement. By sliding up and down between the movable push plate 14 and the vertical rod 15, the stability of the punching head 16 during the punching movement is improved, and displacement during long-term use is prevented.

[0034] Example 3: The existing multi-station cold heading machine cold heading device for fastener processing is not convenient for automatic unloading of the workpiece after processing. Therefore, a through hole 2 and a discharge block 17 are provided. A through hole 2 is opened on the left side of the upper end of the base 1, and the left end of the movable push plate 14 is fixedly connected to the discharge block 17. The movable push plate 14 drives the discharge block 17 to move up and down above the multi-station mold 8, and the discharge block 17 is located above the stamping groove 9 at the corresponding position, as shown in FIG. Figure 4 As shown, after the stamping process is completed, the central processing unit controls the electric telescopic rod 13 to drive the movable push plate 14 to move upward, and at the same time starts the servo motor 4 to drive the multi-station mold 8 to move to the left to transport the material. When the next material moves to the bottom of the punching head 16, the central processing unit controls to close the servo motor 4 and at the same time starts the electric telescopic rod 13 to drive the movable push plate 14 to move downward, so that the punching head 16 performs stamping on the next material. At this time, the workpiece that has been processed previously moves to the left with the multi-station mold 8 to the top of the through hole 2. The opening size of the through hole 2 is not less than the opening size of the punching groove 9. At this time, the workpiece falls from the through hole 2 under the action of gravity, and can also drive the unloading block 17 to move downward through the movable push plate 14. The unloading block 17 knocks the processed workpiece, so that it can pass through the through hole 2 more smoothly for automatic unloading to prevent jamming.
