Description

Technical Field

[0001] This utility model relates to the field of steel bar rolling mills, and more particularly to high-speed rolling mills for cold-rolled ribbed steel bars. Background Technology

[0002] Cold-rolled ribbed steel bars are formed from hot-rolled wire rods through multiple cold rolling reduction processes, followed by rib pressing and stress relief, resulting in steel bars with two or three crescent-shaped surfaces. Cold-rolled ribbed steel bars exhibit excellent bond and anchorage performance with concrete. Therefore, when used in structural members, they fundamentally prevent cracking in the anchorage zone and wire slippage leading to failure. They also improve the load-bearing capacity and crack resistance at the ends of structural members. Cold-rolled ribbed steel bars have a higher elongation than similar cold-worked steels, and their high strength saves on construction steel and reduces project costs. They are widely used in building construction, highways, airports, municipal works, and water and electricity pipelines.

[0003] For example, CN212329252U discloses a high-speed double-line, two-sided ribbed cold-rolled steel bar continuous rolling mill, which can use a power device to increase the speed of the lower roller, improve working efficiency, reduce energy consumption, and improve practicality. It includes a worktable, a horizontal plate, a horizontal beam, a hydraulic cylinder, a piston, a connecting block, and a lower roller. Support legs are respectively set at the four corners of the bottom of the worktable, and a horizontal plate is connected between the four sets of support legs. The hydraulic cylinder is located at the top of the horizontal beam and is connected to a hydraulic pump. The bottom of the hydraulic cylinder is slidably connected to the top of the piston. The bottom of the piston passes through the horizontal beam and is connected to the top of the connecting block. An upper roller is set at the bottom of the connecting block. The two ends of the upper roller are rotatably connected to the bottom of the connecting block. Two sets of vertical plates are set at the top of the worktable, and the lower roller is located between the two sets of vertical plates. A power device is connected to the left end of the lower roller. Steel bar rib grooves are set on both the upper roller and the lower roller.

[0004] Solid particles such as dust can accumulate on the surface of steel bars. This dust can adhere to the surface and enter the space between the rolls and the steel bar, potentially causing defects such as scratches, pits, or dents on the surface during the rolling process. These defects not only affect the appearance of the steel bars but can also become stress concentration points, reducing their mechanical properties. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a high-speed cold-rolled ribbed steel bar mill, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-speed cold-rolled ribbed steel bar mill, comprising a base, a vertical plate fixedly connected to the top of the base, a rolling mill roller rotatably connected to the front of the vertical plate, a first support plate fixedly connected to the top of the base, a cleaning mechanism provided on the top of the first support plate, the cleaning mechanism comprising a motor, the motor fixedly connected to the top of the first support plate, a rotating rod fixedly connected to the output end of the motor via a coupling, a gear fixedly connected to the outer wall of the rotating rod, a second support plate fixedly connected to the top of the base, a rotating ring rotatably connected inside the second support plate, a gear ring fixedly connected to the outer wall of the rotating ring, the gear ring meshing with the gear.

[0007] As a further technical solution of this utility model, the inner wall of the rotating ring is provided with six connecting grooves, and connecting blocks are slidably connected inside the six connecting grooves. Cleaning brushes are fixedly connected to the inner sides of the six connecting blocks respectively.

[0008] As a further technical solution of this utility model, a fixing ring is fixedly connected to the top of each of the six connecting blocks, and a first spring is provided inside the six fixing rings. The first spring is circular.

[0009] As a further technical solution of this utility model, a ring is fixedly connected to the top of the base, and six protrusions are fixedly connected to the inner wall of the ring. When the motor is started, the rotating rod is driven to rotate through the coupling. The gear on the rotating rod rotates accordingly, and the gear meshes with the gear ring, driving the rotating ring to rotate within the second support plate. During the rotation of the ring, the cleaning brush performs a rotary cleaning on the surface of the steel bar passing through it, effectively removing impurities such as dust and iron filings. The inner wall of the ring is provided with six protrusions. During the rotation of the ring, the protrusions periodically contact the connecting block, pushing the connecting block to produce radial micro-movement within the connecting groove. The cleaning brush produces a slight reciprocating movement while rotating, causing a small relative displacement between the bristles and the surface of the steel bar, enhancing the cleaning effect, breaking the adhesion of impurities, and improving the thoroughness of cleaning.

[0010] As a further technical solution of this utility model, a blowing mechanism is provided on the top of the base. The blowing mechanism includes three abutting rods, which are fixedly connected to the right side of the rotating ring.

[0011] As a further technical solution of this utility model, a fixing plate is fixedly connected to the top of the base, a movable rod is fixedly connected to the top of the fixing plate, an abutment plate is movably sleeved on the outer wall of the movable rod, and a second spring is movably sleeved on the outer wall of the movable rod.

[0012] As a further technical solution of this utility model, an airbag is fixedly connected to the top of the fixed plate. The airbag is in contact with the contact plate. An air blowing pipe is connected to the top of the airbag through a one-way valve. The contact plate is movably sleeved on the outer wall of the air blowing pipe. Three contact rods are fixed on the right side of the rotating ring and rotate synchronously with the rotating ring. During the rotation, the contact rods periodically contact and squeeze the contact plate. The contact plate is movably sleeved on the movable rod and is reset by the second spring, forming a reciprocating motion. The contact plate reciprocates to squeeze the airbag, causing high-pressure airflow to be generated inside the airbag. The high-pressure airflow enters the air blowing pipe through the one-way valve and blows towards the surface of the steel bar, further removing the fine particles or dust remaining on the surface of the steel bar, improving the surface cleanliness, preventing impurities from entering between the roll and the steel bar, and avoiding rolling defects.

[0013] This utility model provides a high-speed rolling mill for cold-rolled ribbed steel bars, which has the following advantages compared with the prior art:

[0014] 1. The high-speed cold-rolled ribbed steel bar mill designed in this paper uses multiple cleaning brushes inside the rotating ring to perform all-round rotational cleaning of the steel bar surface. This effectively removes solid particles such as dust and iron filings from the steel bar surface, preventing impurities from entering between the rolls and the steel bar, and avoiding defects such as scratches and pitting during the rolling process. In addition, the protrusions periodically collide with the connecting blocks during the rotation of the rotating ring, causing the connecting blocks and their fixed cleaning brushes to move slightly back and forth in the radial direction. While the cleaning brushes are rotating and cleaning, they are pushed by the protrusions to produce radial micro-movements, which creates a small relative displacement between the brush bristles and the steel bar surface. This effectively breaks the adhesion between impurities and the steel bar surface, improving cleaning efficiency and thoroughness.

[0015] 2. The cold-rolled ribbed steel bar high-speed rolling mill of this design has a blowing mechanism that drives the rotating ring to periodically squeeze the air bag, generating a high-pressure airflow, which is blown onto the surface of the steel bar through the air blowing pipe to further remove fine particles or dust that the cleaning brush could not completely remove, thereby improving the surface cleanliness.

Six protrusions 522 are fixedly connected to the inner wall of the circular ring 521. The motor 511 is started, which drives the rotating rod 512 to rotate via a coupling. The gear 513 on the rotating rod 512 rotates accordingly, meshing with a gear ring 516, driving the rotating ring 515 to rotate within the second support plate 514. During the rotation of the rotating ring 515... The cleaning brush 518 performs a rotary cleaning of the surface of the steel bars passing through it, effectively removing impurities such as dust and iron filings. The inner wall of the ring 521 has six protrusions 522. During the rotation of the ring 515, the protrusions 522 periodically contact the connecting block 517, pushing the connecting block 517 to produce radial micro-movements in the connecting groove.

The inner wall of the ring 521 has six protrusions 522. During the rotation of the ring 515, the protrusions 522 periodically contact the connecting block 517, pushing the connecting block 517 to produce radial micro-movements within the connecting groove. The cleaning brush 518, while rotating, produces a slight reciprocating movement, causing the bristles to form a... The slight relative displacement enhances the cleaning effect, breaks the adhesion of impurities, and improves the thoroughness of cleaning. Three abutment rods 611 are fixed on the right side of the rotating ring 515 and rotate synchronously with the rotating ring 515. During the rotation, the abutment rods 611 periodically contact and squeeze the abutment plate 615. The abutment plate 615 is movably sleeved on the movable rod 613 and is reset by the second spring 614, forming a reciprocating motion.
