DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] In the embodiment, Figure 1 、 Figure 2 As shown, the automatic bolt forging production line includes a No. 1 conveyor belt 1 and also includes:

[0028] Feeder 2, arranged at the feeding end of conveyor belt No. 1;

[0029] A push plate 3 is provided at the discharge end of the No. 1 conveyor belt 1 and is equipped with a No. 1 power element;

[0030] A workbench 4 is provided at the discharge end of the No. 1 conveyor belt 1, and a U-shaped heating ring 5 is provided at one end of the workbench 4;

[0031] A push rod 6 is provided at the end of the U-shaped heating coil 5 and is equipped with a second power element;

[0032] The second conveyor belt 7 is arranged on the other side of the workbench 4 and is arranged parallel to the first conveyor belt 1;

[0033] The robot 8 is arranged on one side of the second conveyor belt 7;

[0034] Punch 9, arranged on one side of the manipulator 8;

[0035] The third conveyor belt 10 is vertically arranged at the end of the second conveyor belt 7.

[0036] The feeder 2 is a step-by-step lifting loader. Both the No. 1 and No. 2 power elements are cylinders. The feeder 2 conveys the blank to the No. 1 conveyor belt 1, and then pushes the blank to the workbench 4 through the push plate 3. After one end of the blank is heated by the U-shaped heating ring 5, the push rod 6 pushes the blank out of the U-shaped heating ring 5, and then the push plate 3 pushes another blank to the workbench 4. The heated blank enters the No. 2 conveyor belt 7, and is sent to the punch press 9 for forging through the manipulator 8. Finally, the manipulator sends the forged blank to the No. 3 conveyor belt 10 to complete the next process; the entire forging process is fully automated, which can effectively improve work efficiency.

[0037] In the embodiment, Figure 1 As shown, the push plate 3 is L-shaped. The push plate 3 pushes the blank into the same position on the workbench.

[0038] In the embodiment, Figure 1 As shown, a limit plate 11 is installed at the other end of the workbench 4, and the limit plate 11 corresponds to the U-shaped heating ring 5. The limit plate 11 limits the other end of the blank to ensure that the heated end of each blank is the same length, thereby ensuring the quality of the forged pier head of the bolt.

[0039] In the embodiment, Figure 1 、 Figure 2 As shown, the working surface of the workbench 4 is higher than the conveying surface of the No. 2 conveyor belt 7. A guide plate 12 is provided on the side of the workbench 4 close to the No. 2 conveyor belt 7, and a baffle 13 is provided on the side of the No. 2 conveyor belt 7 away from the workbench 4. The heated blank rolls onto the No. 2 conveyor belt 7 via the guide plate 12, facilitating the heated blank's entry onto the No. 2 conveyor belt 7.

[0040] In the embodiment, Figure 1 As shown, an oxide scale cleaning machine 14 is provided on one side of the No. 3 conveyor belt 10, and the oxide scale cleaning machine 14 is located between the workbench 4 and the manipulator 8. After removing the oxide scale, the quality of the forging can be improved, and the mold can be protected and the wear of the mold can be reduced.

[0041] In the embodiment, Figure 3 As shown, a cooling hole 15 is provided in the center of the push rod 6. A connecting hole 16 for communication with the cooling hole 15 is provided at one end of the push rod 6, which is close to the second power element. The push rod 6 is made of a white high-temperature material such as a ceramic alloy or alloy steel. By ventilating the cooling hole 15, the push rod 6 is quickly cooled, ensuring the service life of the push plate 6.

[0042] In the embodiment, the second conveyor belt 7 and the third conveyor belt 10 are both stainless steel chain conveyor belts. Stainless steel chain conveyor belts are resistant to high temperatures, are not easily damaged by heated blanks, and have a long service life.
