[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This utility model eliminates air bubbles and gaps in raw materials by installing a vibration mechanism. Existing raw materials often contain air bubbles or gaps when added to the pouring hole, or there are gaps between the raw materials and the pouring hole, which leads to a decrease in product quality. Therefore, this needs to be improved. First, the drive motor drives the threaded screw to rotate, and the sliding block moves on the threaded screw, causing the pouring module to move laterally and vibrate. The electric push rod drives the pouring module to move up and down and vibrate, thereby making the raw materials fully and evenly dispersed in the pouring hole, reducing air bubbles and gaps. After the vibration is completed, the pouring module needs to be reset so that the contact rod is located in the contact groove and the contact rod presses the contact button. The alarm light illuminates, indicating that the pouring module has returned to its original position and the molding process can begin.
[0017] 2. This utility model, by installing a protective mechanism, prevents the raw material from falling out of the casting module during the bubble elimination process. During the bubble elimination process, vibration can cause the raw material to fall out of the casting module, thus requiring improvement. First, a first and second Velcro strap is used to install a sealing layer in the slot to seal the casting hole. Then, the motor rotates, causing the reinforcing plate to rotate, thus sealing the slot a second time and preventing the raw material from falling out. When forming the bolt, the reinforcing plate rotates to the top of the slot, and then the sealing layer is removed from the slot, allowing the bolt to be formed through the slot.

[0027] Please see Figure 1 and Figure 2A multi-station cold heading forming device for high-strength bolts includes: a forming platform 1, a plate 2, and a forming module 4. The plate 2 is located on the top of the forming platform 1. A forming electric rod 3 is installed on the outer wall of the plate 2. The output end of the forming electric rod 3 is installed with the forming module 4. A forming die head 5 is installed on the outer wall of the forming module 4. A casting module 6 is located on the top of the forming platform 1. A casting hole 7 is located on the outer wall of the casting module 6. A demolding electric rod 8 is installed on the outer wall of the casting module 6. A demolding module 9 is installed on the output end of the demolding electric rod 8. Raw materials are added into the casting hole 7. Then, the forming electric rod 3 operates to drive the forming module 4 to move. The forming die head 5 is used to perform cold pressing forming on the casting hole 7. After forming, the demolding electric rod 8 operates to drive the demolding module 9 to move and eject the product from the casting hole 7.
[0028] Please see Figure 3 and Figure 4 The top of the molding platform 1 is equipped with a vibration mechanism to eliminate air bubbles and gaps in the raw material. The vibration mechanism includes a transverse groove 10, a sliding block 13, and an electric push rod 14. The outer wall of the molding platform 1 is provided with a transverse groove 10, and a drive motor 11 is installed on the inner wall of the transverse groove 10. A threaded screw 12 is installed at the output end of the drive motor 11. A sliding block 13 is installed around the outer wall of the threaded screw 12, and an electric push rod 14 is embedded in the outer wall of the sliding block 13. The output end of the electric push rod 14 is fixedly connected to the bottom of the casting module 6. A contact rod 15 is installed on the outer wall of the casting module 6, and an alarm light 16 is installed on the top of the contact rod 15. The top of the molding platform 1 is provided with a contact groove 17, and a contact button 18 is installed on the inner wall of the contact groove 17. When some raw materials are added to the pouring hole 7, air bubbles or voids often appear in the raw materials or there are gaps between the raw materials and the pouring hole 7, which leads to a decrease in product quality. Therefore, this needs to be improved. First, the drive motor 11 works to drive the threaded screw 12 to rotate. The sliding block 13 moves on the threaded screw 12, causing the pouring module 6 to move laterally and vibrate. The electric push rod 14 works to drive the pouring module 6 to move up and down and vibrate, thereby making the raw materials fully and evenly dispersed in the pouring hole 7, reducing air bubbles and voids. At the same time, after the vibration is completed, the pouring module 6 needs to be reset, so that the contact rod 15 is located in the contact groove 17 and the contact rod 15 presses the contact button 18. The alarm light 16 lights up, indicating that the pouring module 6 has returned to its original position and the molding work can be carried out.
[0029] Please see Figure 2 and Figure 5The outer wall of the casting module 6 is provided with a protective mechanism to prevent raw materials from falling out of the casting module 6 during the process of eliminating air bubbles. The protective mechanism includes a protective plate 19 and a sealing layer 23. The protective plate 19 is disposed on the outer wall of the casting module 6, and the inner wall of the protective plate 19 has slots 20. A first Velcro 21 is installed on the outer wall of the casting module 6, a second Velcro 22 is installed on the outer wall of the first Velcro 21, and a sealing layer 23 is installed on the outer wall of the second Velcro 22. The outer wall of the protective plate 19 has a rotating groove 24, and a rotating motor 25 is installed on the inner wall of the rotating groove 24. The output end of the rotating motor 25 is equipped with a... When the reinforcing plate 26 vibrates during the process of eliminating air bubbles in the raw material, the raw material may fall out of the casting module 6. Therefore, this needs to be improved. First, the sealing layer 23 is installed in the slot 20 using the first Velcro 21 and the second Velcro 22 to seal the casting hole 7. Then, the motor 25 is rotated to drive the reinforcing plate 26 to rotate, so that the reinforcing plate 26 seals the slot 20 a second time, thereby preventing the raw material from falling out. When the bolt is being formed, the reinforcing plate 26 is rotated to the top of the slot 20, and then the sealing layer 23 is removed from the slot 20, so that the bolt is formed through the slot 20.
[0030] The working principle is as follows: raw materials are added into the pouring hole 7. Then, the forming rod 3 moves the forming module 4, and the forming die head 5 performs cold-press forming on the pouring hole 7. After forming, the demolding rod 8 moves the demolding module 9 to eject the product from the pouring hole 7. Currently, when raw materials are added to the pouring hole 7, air bubbles or voids often appear in the raw materials, or there are gaps between the raw materials and the pouring hole 7, leading to reduced product quality. Therefore, improvements are needed. First, the drive motor 11 rotates the threaded screw 12, and the sliding block 13 moves on the threaded screw 12, causing the pouring module 6 to move laterally and vibrate. The electric push rod 14 moves the pouring module 6 up and down, causing it to vibrate. This ensures that the raw materials are evenly dispersed in the pouring hole 7, reducing air bubbles and voids. After vibration, further adjustments are needed. When the casting module 6 is reset, the contact rod 15 is positioned in the contact groove 17, and the contact rod 15 presses against the contact button 18, illuminating the alarm light 16. This indicates that the casting module 6 has returned to its original position and can proceed with the molding process. During the process of eliminating air bubbles in the raw material and vibrating, the raw material may fall out of the casting module 6. Therefore, this needs to be improved. First, the sealing layer 23 is installed in the slot 20 using the first Velcro 21 and the second Velcro 22 to seal the casting hole 7. Then, the motor 25 is rotated to drive the reinforcing plate 26 to rotate, so that the reinforcing plate 26 provides a secondary seal to the slot 20, thereby preventing the raw material from falling out. When molding the bolt, the reinforcing plate 26 is rotated to the top of the slot 20, and then the sealing layer 23 is removed from the slot 20, allowing the bolt to be molded through the slot 20.
