Description

Technical Field

[0001] The invention relates to the technical field of ribbed steel bar production, in particular to a high-ductility cold-rolled ribbed steel bar rolling device. Background Art

[0002] Cold rolling of ribbed steel bars is a metalworking process. It is a process of rolling the steel bars through the rollers of a cold rolling mill to form ribs on the surface of the steel bars. In this process, the steel bars pass between two or more rollers with specific grooves or raised patterns. When the steel bars are rolled, the pressure of the rollers causes the shape of the steel bars to change, thus forming ribs on the surface of the steel bars.

[0003] Before the existing ribbed steel bar rolling device rolls the steel bar, it is necessary to clean the iron filings and debris on the surface of the steel bar, mainly to improve the effect of the steel bar rolling. Now a brush is often used to sweep the iron filings and debris on the surface of the steel bar. This method requires frequent cleaning or replacement of the brush itself to avoid iron filings and debris being mixed in the bristles of the brush, resulting in a significant reduction in the cleaning effect. During the replacement process, the production operation needs to be suspended, resulting in low rolling production efficiency.

[0004] Based on this, a high-ductility cold-rolled ribbed steel bar rolling device is now provided, which can eliminate the disadvantages of the existing devices. Summary of the invention

[0031] The dust collecting module 6 is arranged on one side of the cleaning assembly 3, and is used to clean the iron filings on the surface of the brush roller 30;

[0032] The driving module 7 is arranged above the dust collection module 6 and the adaptive cleaning module 8, and is used to drive the brush roller 30 to rotate and clean.

[0033] When the steel bar passes through the cleaning component 3, it contacts the three inclined plates 22. The inclined plates 22 push the adaptive plates 23 in a direction away from the center of the circle. The thicker the steel bar, the greater the movement distance of the adaptive plates 23, thereby achieving adaptive fitting of the brush roller 30 to the surface of the steel bar. No manual adjustment is required, the operation is quick and convenient, and the application range of the device is improved.

[0034] In one embodiment, two symmetrical second slider grooves are provided on the upper surface of the adaptive plate 23, and the second slider groove inner wall is slidably connected to the second slider 34, and the upper surface of the second slider 34 is fixedly connected to the lifting and retracting rod 33, and the lifting and retracting rod 33 passes through and is slidably connected to the fixed cylinder 31, and the lifting and retracting rod 33 is fixedly connected to the inner wall of the fixed cylinder 31 with a spring, and the upper surface of the fixed cylinder 31 is fixedly connected to the first slider 32, and the inner ring side wall of the rotating cylinder 18 is provided with six first slider grooves opposite to each other, and the first slider 32 is slidably connected to the inner wall of the first slider groove.

[0035] The lifting and retracting rod 33 is compressed into the fixing tube 31 , and under the action of the spring force in the fixing tube 31 , the brush roller 30 is pressed tightly against the surface of the steel bar.

[0036] In one embodiment, the dust collection module 6 includes a second base 10 and a dust collector 11. The upper surface of the adaptive plate 23 is rotatably connected to two symmetrical third rotating shafts 29 through a bearing seat. The third rotating shaft 29 and the second rotating shaft 27 are driven by a synchronous belt driving member 28. The two third rotating shafts 29 are fixedly connected to a cam 35. The upper surface of the adaptive plate 23 is fixedly connected to two symmetrical guide rods 26 through a bracket. The two guide rods 26 penetrate and slide through a reciprocating frame 25. The reciprocating frame 25 is provided with two cam boxes. The cam 35 abuts against the inner side wall of the cam box.

[0038] When the brush roller 30 revolves, the brush roller 30 rotates on its own because the brush roller 30 is in close contact with the surface of the steel bar. The rotation of the brush roller 30 drives the second rotating shaft 27 to rotate. The second rotating shaft 27 drives the third rotating shaft 29 to rotate through the synchronous belt driving member 28. The third rotating shaft 29 drives the cam 35 to rotate. During the rotation of the cam 35, the reciprocating frame 25 is driven to make a horizontal reciprocating movement on the guide rod 26. The reciprocating movement of the reciprocating frame 25 drives the cleaning plate 36 to reciprocate, and the bristles on the surface of the brush roller 30 are turned over. The vacuum cleaner 11 is started, and the vacuum cleaner 11 sucks air through the pipe and the bellows 21 , so that the air pressure in the semi-cylinder 37 is lower than the external air pressure. At this time, the external airflow passes through the bristles on the surface of the brush roller 30 and flows into the semi-cylinder 37. During the flow of the airflow, the iron filings and impurities mixed in the bristles of the brush roller 30 are sucked into the semi-cylinder 37, and then enter the vacuum cleaner 11 through the bellows 21 and the pipeline, thereby completing the cleaning of the iron filings mixed in the brush roller 30. There is no need for manual frequent cleaning and replacement of the brush roller 30, and there is no need to stop the machine, which improves the production efficiency. The brush roller 30 is always kept in a relatively clean state to clean the surface of the steel bar, thereby improving the cleaning effect of the brush roller 30 on the steel bar.

[0044] S1: First, the steel bar is passed through the conveyor 2, the cleaning component 3, and the three-roll cold rolling mill 1 in sequence. When the steel bar passes through the cleaning component 3, it contacts the three inclined plates 22. The inclined plates 22 push the adaptive plates 23 in a direction away from the center of the circle, and the lifting and retracting rods 33 are compressed into the fixed cylinder 31. Under the action of the spring force in the fixed cylinder 31, the brush roller 30 is pressed tightly against the surface of the steel bar. The thicker the steel bar, the greater the moving distance of the adaptive plate 23, so that the brush roller 30 and the steel bar surface can be adaptively fitted, no manual adjustment is required, the operation is quick and convenient, and the application range of the device is improved.

[0045] S2: Start the motor 16, the motor 16 drives the first rotating shaft 17 to rotate, the first rotating shaft 17 drives the first gear 14 and the second gear 15 to rotate, the first gear 14 drives the second gear ring 13 to rotate, the second gear ring 13 drives the rotating cylinder 18 to rotate, the rotating cylinder 18 drives the three adaptive plates 23 to revolve around the steel bar, at this time, the brush roller 30 contacts the surface of the steel bar, and rotates to clean the iron filings and impurities on the surface of the steel bar, thereby improving the cleaning effect on the surface of the steel bar;

[0046] S3: While the brush roller 30 is revolving, the brush roller 30 is in close contact with the surface of the steel bar, so that the brush roller 30 rotates, and the rotation of the brush roller 30 drives the second rotating shaft 27 to rotate, and the second rotating shaft 27 drives the third rotating shaft 29 to rotate through the synchronous belt driving member 28, and the third rotating shaft 29 drives the cam 35 to rotate. During the rotation of the cam 35, the reciprocating frame 25 is driven to make a horizontal reciprocating movement on the guide rod 26. The reciprocating movement of the reciprocating frame 25 drives the cleaning plate 36 to reciprocate, and the bristles on the surface of the brush roller 30 are turned over, and the vacuum cleaner 11 is started, and the vacuum cleaner 11 is sucked through the pipe and the bellows 21 Air is passed through the brush roller 30, so that the air pressure in the semi-cylinder 37 is lower than the external air pressure. At this time, the external airflow passes through the bristles on the surface of the brush roller 30 and flows into the semi-cylinder 37. During the flow of air, the iron filings and impurities mixed in the bristles of the brush roller 30 are sucked into the semi-cylinder 37, and then enter the vacuum cleaner 11 through the bellows 21 and the pipeline, thereby completing the cleaning of the iron filings mixed in the brush roller 30.
