[0030] This utility model provides a technical solution: such as Figure 1 and Figure 2As shown, in this embodiment, the bearing steel ball billet medium-frequency heating continuous rolling device includes a support base 1. A transmission roller cleaning assembly 3 is arranged and installed on the lower part of the inner wall of the support base 1. A pressure roller cleaning assembly 2 is bolted to the top side of the support base 1. Multiple sets of pressure roller cleaning assemblies 2 are provided, enabling continuous rolling of the bearing steel ball billet. A collection groove 11 is provided on the bottom side inside the support base 1. A guide plate 13 is provided on the inner wall of the collection groove 11. A slag discharge groove 12 is provided on one side of the collection groove 11 and at the lower end of the guide plate 13. Transmission rollers 14 are arranged on the lower part of the inner wall of the support base 1. Several rollers 14 are provided. A drive motor 15 is provided at one end of the left drive roller 14. Cylindrical gears 16 are sleeved on one side of each drive roller 14. Adjacent cylindrical gears 16 are meshed together. Pressure rollers 17 are provided above the inner wall of the support base 1. The number of pressure rollers 17 is the same as the number of mounting plates 21. The pressure rollers 17 are connected by a drive chain. A motor is installed at the rear end of each pressure roller 17. Through the provided collection trough 11, slag discharge trough 12 and guide plate 13, the scraped foreign objects are collected in the collection trough 11 and can be discharged from the slag discharge trough 12 through the guide plate 13, which facilitates collection and cleaning.

[0031] like Figure 2 and Figure 4 As shown, the pressure roller cleaning assembly 2 includes a mounting plate 21. A bidirectional lead screw 22 is provided in the groove on the bottom side of the mounting plate 21. Movable plates 26 are threaded to the outer walls of both ends of the bidirectional lead screw 22. Electric push rods 27 are provided on the bottom side of each movable plate 26. The motor model is YBX3 and the electric push rod model is YS607. Cleaning plates 28 are fixedly connected to the bottom side of each electric push rod 27. A driving bevel gear 23 is provided in the middle of the bidirectional lead screw 22. A driven bevel gear 24 is meshed with the upper teeth of the driving bevel gear 23. The output end of the driven bevel gear 24 passes through the mounting plate 21 and is provided with a drive motor 25. The cleaning plates 28 are positioned above the pressure roller 17 and contact the pressure roller 17 through the electric push rods 27. By installing the pressure roller cleaning assembly 2, the drive motor 25 causes the bidirectional lead screw 22 to rotate through the bevel gear set, thereby causing the cleaning plates 28 at both ends to move and clean the foreign objects adhering to the pressure roller 17.

[0032] like Figure 2 and Figure 3As shown, the transmission roller cleaning assembly 3 includes a collar 31, which is disposed on the inner wall of the front and rear of the support base 1.

By installing the transmission roller cleaning assembly 3, foreign objects adhering to the transmission roller 14 can be scraped off by the scraper 33 while the transmission roller 14 is rotating, thereby reducing the adhesion of foreign objects to the pressure roller 17 and the transmission roller 14, reducing the impact of foreign objects on the bearing steel ball billet during the rolling process, and improving the rolling quality of the bearing steel ball billet.

[0033] This utility model provides a medium-frequency heating continuous rolling device for bearing steel ball billets. The specific working principle is as follows: The drive motor 15 drives the cylindrical gear 16 to rotate, which in turn drives the drive roller 14, causing the medium-frequency heated bearing steel ball billet to move, and thus the drive roller 14 and the pressure roller 17 roll the bearing steel ball billet. After one rolling, the drive motor 25 is started to drive the bevel gear set to rotate, which drives the double-sided lead screw 22 to rotate, causing the movable plate 26 to move on the double-sided lead screw 22. The electric push rod 27 causes the cleaning plate 28 to contact the pressure roller 17. The rotating pressure roller 17, together with the cleaning plate 28, cleans off the adhering foreign matter. During this process, the forward and reverse rotation of the drive motor 25 can be controlled to make the cleaning plates 28 on both sides move back and forth. At the same time, the drive roller 14 can scrape off the adhering foreign matter with the scraper 33 until it is collected in the collection trough 11. The foreign matter is discharged from the slag discharge trough 12 by the guide plate 13.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
