Description

Technical Field

[0001] This invention relates to the field of steel ball production technology, and more specifically to a multi-roller round steel feeding device for steel ball production. Background Technology

[0002] The production process of wear-resistant steel balls can generally be divided into casting, rolling, and forging processes. Rolled and forged steel balls have highly automated production lines. However, the feeding of round steel billets, as part of these processes, still suffers from low automation. To minimize the curvature of the heated round steel billets and ensure their smooth entry into the ball mill or forging machine, the billet length is typically 4–9 meters. However, some steel companies still rely heavily on manual labor for the storage, weighing, cutting, and feeding of round steel billets, resulting in low automation. Furthermore, due to labor and cost considerations, the billets are not always cut to the specified dimensions, affecting the stability of their entry into the ball mill or forging machine and leading to suboptimal product quality. Summary of the Invention

The limit switches are set above the left end of the roller chain. The alignment roller conveyor station is equipped with four length measuring proximity switches for measuring the length range of the round steel billets. When two or more length measuring proximity switches are energized, the alignment roller conveyor station is energized to transport the round steel billets to the limit switches at the left end. After the limit switches are triggered, the alignment roller conveyor station is de-energized and stops transporting the round steel billets.

The round steel bar feeding has a high degree of automation, which greatly reduces labor costs. Moreover, since the round steel bars can be fixed to the size that meets the rolling length of the steel ball rolling mill, the stability of entering the steel ball rolling mill or forging mill for forming is guaranteed, resulting in better quality of the final product.

[0028] See Figure 1-4 As shown, as an embodiment of the present invention, a multi-roller round steel feeding device for steel ball production is provided, including a receiving and conveying unit, a round steel processing unit, a feeding unit, a furnace front turning unit, and a unloading unit that are connected in sequence.

[0029] The receiving and conveying unit includes a receiving platform 1 for storing round steel billets and a conveying assembly for conveying the round steel billets to the round steel processing unit.

[0030] The round steel processing unit consists of multiple units arranged side by side. Each round steel processing unit includes a stepping feeding mechanism, an alignment mechanism, a weighing mechanism, a cutting mechanism, and a top-breaking unloading mechanism. The alignment mechanism, weighing mechanism, and cutting mechanism are arranged sequentially on one side of the stepping feeding mechanism. The stepping feeding mechanism transports the round steel billet from front to back to the alignment mechanism, weighing mechanism, and cutting mechanism. The alignment mechanism is used to drive the round steel billet to move so that the round steel billets arranged side by side are aligned coaxially. The weighing mechanism is used to weigh the round steel billet. The cutting mechanism is used to cut the round steel billet.

[0032] The furnace front turning unit is used to lift the round steel bars on the feeding unit and transport them to the unloading unit to stop feeding.

[0033] The multi-roller round steel feeding equipment for steel ball production of the present invention can automatically store, weigh, cut, and feed round steel billets in the steel ball production process, thereby enabling the round steel billets to be processed into round steel bars that meet the rolling length (4-9m) of the steel ball rolling mill and to smoothly enter the steel ball rolling mill or forging mill for forming. The round steel bar feeding has a high degree of automation, which greatly reduces labor costs. Moreover, since the round steel bars can be fixed to the size that meets the rolling length of the steel ball rolling mill, the stability of entering the steel ball rolling mill or forging mill for forming is guaranteed, resulting in better quality of the final product.

[0034] In this embodiment, the receiving and conveying unit includes a receiving platform 1, a hydraulic lifting cylinder 2, a first motor 3, a rotating shaft 4, a conveyor chain 5, an inclined beam 6, and a blocking mechanism 7. The receiving platform 1 is connected to the top of the hydraulic lifting cylinder 2 and extends to the left and right. The hydraulic lifting cylinder 2 drives the receiving platform 1 to be lifted to a horizontal state. The first motor 3 is driven and connected to the rotating shaft 4. The conveyor chain 5 is connected between the rotating shaft 4 and the receiving platform 1 through gears rotating back and forth. The receiving platform 1 is used to store round steel billets. The inclined beam 6 is inclined between the conveyor chain 5 and the blocking mechanism 7. The inclined beam 6 is inclined downward from front to back. This setting allows the round steel billets to be quickly transported to the alignment mechanism of the round steel processing unit, realizing automated feeding, which is simpler and faster.

[0035] In this embodiment, the stepping feeding mechanism includes a second motor 8, a connecting shaft 9, a first reducer 10, a universal joint 11, a second reducer 12, and a stepping beam 13. The second motor 8 is connected to the first reducer 10 via the connecting shaft 9, and the first reducer 10 is connected to the second reducer 12 via the universal joint 11. There are two second reducers 12 connected by left and right transmission. The left and right ends of the stepping beam 13 are respectively connected to the same side of the two second reducers 12 via cams. The top of the stepping beam 13 is provided with multiple placement positions for placing and stepping transporting round steel billets along the front-to-back direction. This structure enables the stepping beam 13 to transport the round steel billets from front to back to the corresponding processing positions such as the alignment mechanism, weighing mechanism, and cutting mechanism through stepping motion to realize the processing steps of the corresponding positions, saving manpower and achieving a high degree of automation.

[0036] In this embodiment, the billet alignment mechanism includes an alignment roller conveyor station 14, a third motor 15, a roller chain 16, and a limit switch 17. The third motor 15 is driven and connected to the roller chain 16. The alignment roller conveyor station 14 is set on the roller chain 16. The third motor 15 drives the roller chain 16 to move left and right, thereby driving the alignment roller conveyor station 14 to move back and forth in the left and right direction, thereby driving the round steel billet to move so that the round steel billets arranged left and right are aligned coaxially. The limit switch 17 is set above the left end of the roller chain 16. The alignment roller conveyor station 14 is equipped with four length measuring proximity switches for measuring the length range of the round steel billet. When two or more length measuring proximity switches are energized, the alignment roller conveyor station 14 is energized to transport the round steel billet to the limit switch 17 at the left end. After hitting the sensor of the limit switch 17, the alignment roller conveyor station 14 is de-energized and stops transporting the round steel billet.

[0037] In this embodiment, the weighing mechanism includes a weighing roller station 18 and a weighing terminal box 19 disposed on the weighing roller station 18. The weighing terminal box 19 is provided with a weighing device to weigh the round steel billet.

[0038] In this embodiment, the cutting mechanism includes a rotary cutting roller station 20, a fourth motor 21 and a transmission shaft 22. The fourth motor 21 and the transmission shaft 22 are connected in a driving manner. A cutter is provided on the transmission shaft 22 at the rotary cutting roller station 20. The rotary cutting roller station 20 drives the round steel billet to rotate so that the cutter can rotate and cut it.

[0039] In this embodiment, the top-breaking and unloading mechanism includes a hydraulic top-breaking cylinder 23 that can extend and retract back and forth, and an unloading inclined beam 24 that is inclined between the rotary cutting roller station 20 and the loading unit. The hydraulic top-breaking cylinder 23 is used to push out the cut round steel billet on the cutting mechanism, so that the round steel billet is broken to form a round steel bar; the unloading inclined beam 24 is gradually inclined downward from front to back.

[0040] In this embodiment, the feeding unit is a feeding roller conveyor 25, and the furnace front turning unit includes a hydraulic top cylinder 26 and a swing arm turning hook 27 that can swing up and down and is set at the top of the hydraulic top cylinder 26. The swing arm turning hook 27 is used to lift the round steel bar on the feeding unit and transport it to the unloading unit to stop feeding.

[0041] In this embodiment, the unloading unit is an unloading rack 28 with an open top. The inner cavity of the unloading rack 28 is inverted trapezoidal to ensure the neatness of the stacked round steel bars.

[0042] The working process of this invention is as follows: The crane in the workshop lifts the round steel billet to the receiving platform 1. The hydraulic lifting cylinder 2 lifts the receiving platform 1 to a horizontal state. The first motor 3 drives the rotating shaft 4 to rotate, which in turn drives the conveyor chain 5 to move backward and transport the round steel billet to the inclined beam 6. Then, under its own gravity, the round steel billet moves backward and downward along the inclined beam 6 until it reaches the blocking mechanism 7. Then, the second motor 8 drives the first reducer 10 and the second reducer 12 to rotate. The second reducer 12 drives the stepping beam 13 to move backward in a stepping motion (the movement trajectory is in the shape of a square). The stepping beam 13 feeds and transports the round steel billet through the stepping motion, so that the round steel billet moves from front to back to different roller conveyor positions in sequence. The stepping beam 13 first transports the round steel billet at the material blocking mechanism 7 to the alignment roller conveyor station 14 through stepping motion. The third motor 15 controls the single-row roller chain 16 to move left and right, thereby driving the alignment roller conveyor station 14 to move back and forth in the left and right direction, thereby driving the round steel billet to move so that the round steel billets arranged left and right are aligned coaxially. The length range of the round steel billet is measured by the four length measuring proximity switches on the alignment roller conveyor station 14. When two or more length-measuring proximity switches are energized, the roller conveyor is powered and transports the round steel billet to the top limit switch 17. Upon contact with the limit switch 17 sensor, the roller conveyor is de-energized and stops transporting the round steel billet. Subsequently, the walking beam 13 continues its stepping motion, transporting the round steel billet from the aligned roller conveyor station 14 to the weighing roller conveyor station 18. The weighing device in the terminal box 19 under the weighing roller conveyor station 18 weighs each individual round steel billet and feeds the weight signal back to the steel ball production process system. Then, the walking beam 13 continues its stepping motion, transporting the round steel billet from the weighing roller conveyor station 18 to the rotary cutting roller conveyor station 20. The fourth motor 21 drives the drive shaft 22 to rotate, thereby driving the cutter to rotate. The rotary cutting roller conveyor station 20 drives the round steel billet to rotate for cutting by the cutting blade. Then, the hydraulic jacking cylinder 23 pushes out the cut round steel, thereby breaking the round steel billet into round steel bars that meet the rolling length of the steel ball mill. Finally, the walking beam 13 continues to move forward, transporting the round steel bars on the rotary cutting roller conveyor station 20 to the unloading inclined beam 24. The round steel bars move backward and downward at the unloading inclined beam 24 to the loading roller conveyor 25 for subsequent processes. When the production line malfunctions and needs to be stopped urgently, the hydraulic jacking cylinder 26 in the furnace front turning mechanism can lift the swing arm turning hook 27, thereby lifting the round steel bars on the loading roller conveyor 25 and conveying them to the furnace front unloading rack 28 to stop the feeding.
