[0033] Embodiment

[0034] In a specific embodiment of the present utility model, as Figures 1 - 5As shown in the figure, this device is used in cooperation with the material receiving plate 23, the back plate of the guide plate rack 1, and the graphite electrode 24. This device is installed below the back plate of the guide plate rack 1. A flange rack 15 is fixedly connected to the middle of the back plate of the guide plate rack 1. A slideway groove 17 is bolted to the back plate of the guide plate rack 1. The slideway groove 17 and the flange rack 15 are on the same horizontal plane. A lifting oil cylinder 4 is installed above the flange rack 15. The piston of the lifting oil cylinder 4 passes through the middle through hole of the flange rack 15. An earring 21 is provided below the piston of the lifting oil cylinder 4. The earring 21 is inserted into the horizontal platform 5 through a pin through an open split pin 22. The middle of the horizontal platform 5 is fixedly connected to the guide frame 6 through an annular plate 19. The upper part of the guide frame 6 is inserted into the slideway groove 17. Both the lifting oil cylinder 4 and the guide frame 6 are in a vertical state, and the connected horizontal platform 5 is in a horizontal state. A linear rolling guide 20 is provided on the connecting frame 16 below one side of the horizontal platform 5. The sounding rod frame 25 is bolted to the linear rolling guide 20. The limit oil cylinder is clamped to the sounding rod frame 25 through a cylinder rack. A sounding rod baffle 7 and a limit baffle 9 are respectively provided on both sides of the sounding rod cylinder 8. A proximity switch one 10 and a proximity switch two 11 are provided between the sounding rod cylinder 8 and the limit baffle 9. The printing oil cylinder 12 is connected to the character size groove plate 13 through the annular plate 19, and the character size groove plate 13 clamps and fixes the character size 14.

[0035] In the PLC electric control system, input the character size 14 to print a depth of 16 mm that needs to be printed. Set the reciprocating time interval of the printing device according to the extrusion electrode time. The PLC electric control system controls the lifting oil cylinder 4 to lower the printing device 2 to a specified position above the material receiving plate 23. At the same time, it controls the printing oil cylinder 12 to extend 16 mm towards the character size groove plate 13, and controls the sounding rod cylinder 8 to extend 16 mm towards the sounding rod baffle 7. The graphite electrode 24 sorted above the material receiving plate 23 continues to move forward at the original speed. The graphite electrode 24 contacts the character size 14 and the sounding rod baffle 7. When the character size 14 is pressed into the graphite electrode 24 to reach 16 mm, the sounding rod baffle 7 squeezes the sounding rod cylinder 8 to contract. The sounding rod cylinder 8 moves 16 mm towards the limit baffle 9 due to the extrusion of the graphite electrode 24 and reaches the position of the proximity switch two 11 to trigger the proximity switch two 11. The PLC electric control system controls the rapid retraction of the lifting oil cylinder 4, the printing oil cylinder 12, and the sounding rod cylinder 8 to complete the printing of the graphite electrode 24. The printed graphite electrode 24 continues to move on the material receiving plate 23. The operator replaces the character size 14. After reaching the set time, the PLC electric control system controls the lifting oil cylinder 4 to lower the printing device 2 to the specified position above the material receiving plate 23 again for printing again.

[0036] During the continuous printing process of this device, the guide frame 6 reciprocates along the slideway groove 17. When jamming occurs, this device quantitatively adds lubricating oil into the slideway groove 17 through the oil cup 18 to keep the lifting of the printing device 2 stable.
