Technical Field

[0001] This utility model belongs to the technical field of steel wire oxide scale removal, and relates to an online and efficient device for removing steel wire oxide scale after heat treatment. Background Technology

[0002] During steel wire production, heat treatment (such as lead quenching and annealing) forms a dense iron oxide scale on the surface (mainly composed of ferrous oxide, magnetite, and ferric oxide). The presence of this oxide layer severely affects the quality of subsequent drawing, plating, and other processing steps, thus requiring thorough removal. Currently, commonly used industrial methods for removing iron oxide scale include hydrochloric acid pickling, electrolytic sulfuric acid pickling, and ultrasonic phosphoric acid pickling. However, these methods all have significant technical drawbacks. Hydrochloric acid pickling and electrolytic sulfuric acid pickling cause substantial environmental pollution and pose safety hazards due to their strong acid composition. Ultrasonic phosphoric acid pickling generates a large amount of sludge that is difficult to remove. Therefore, a more efficient, environmentally friendly, and safe alternative is urgently needed.

[0019] This utility model provides an online, high-efficiency device for removing oxide scale from heat-treated steel wire, the structure of which is as follows: Figure 1-5 As shown, the system includes a frame 12 and linear guide rails 11. Four linear guide rails 11 are arranged in parallel on the frame 12, and both ends of the linear guide rails 11 are fixed to the frame 12 by bolts. A motor-side side plate 16a is fixed to the left side of the linear guide rails 11, and an operating-side side plate 16b is fixed to the right side of the linear guide rails 11. A motor-side movable seat 9 and an operating-side movable seat 10 are slidably mounted on the linear guide rails 11, located outside the motor-side side plate 16a and the operating-side side plate 16b, respectively. The cylinder body of the moving cylinder 13 is fixed to the motor-side movable seat 9, and the piston rod of the moving cylinder 13 has a free end... After passing through the motor-side movable seat 9, it abuts against the inner side of the motor-side side plate 16a. When the movable cylinder 13 is working, the movable cylinder 13 drives the motor-side movable seat 9 to reciprocate linearly along the linear guide rail 11. A motor-side bearing seat 5 is fixedly installed on the motor-side movable seat 9, and an operating-side bearing seat 6 is fixedly installed on the operating-side movable seat 10. The two ends of the main shaft 2 are supported by the motor-side bearing seat 5 and the operating-side bearing seat 6, respectively. The wire roller brush 1 is fixed on the main shaft 2. The motor 4 is fixedly installed on the motor-side movable seat 9, and the output shaft of the motor 4 is coaxially connected to the main shaft 2 through the coupling 3.

[0020] Furthermore, the motor-side bearing housing 5 is used to maintain the rigid support of the main shaft 2 when the wire brush 1 is disassembled; the operating-side bearing housing 6 is removed when the wire brush 1 is replaced to free up operating space, facilitate replacement operations, and play a role in maintaining the stable operation of the main shaft 2 during equipment operation.

[0021] Furthermore, the motor-side bearing seat 5 is mounted on the motor-side movable seat 9 via the adjusting screw 7a and the adjusting guide rail 8; the adjusting screw 7a is supported on the adjusting seat 22 by a pair of angular contact bearings 21 below, and a bevel gear 23 is installed at the tail end of the adjusting screw 7a, which meshes with another bevel gear 23 at one end of the guide rod 24; the operating-side bearing seat 6 is mounted on the operating-side movable seat 10 via the synchronous adjusting screw 7b and the adjusting guide rail 8; the synchronous adjusting screw 7b is supported on the adjusting seat 22 by a pair of angular contact bearings 21 below, and a bevel gear 23 is installed at the tail end of the synchronous adjusting screw 7b, which meshes with another bevel gear 23 at the other end of the guide rod 24; one end of the guide rod 24 is connected to a handwheel 25, and when the handwheel 25 is rotated, the adjusting screw 7a and the synchronous adjusting screw 7b are driven to rotate synchronously through the bevel gear 23, thereby driving the motor-side bearing seat 5 and the operating-side bearing seat 6 to work together to achieve synchronous adjustment of the clamping force of the main shaft 2.

[0022] Furthermore, pressure rollers 17 are horizontally arranged on the left and right sides of the main shaft 2; a support roller 14 is arranged vertically on the main shaft 2; the two ends of the spindle 15 of the support roller 14 are fixed on the motor side plate 16a and the operation side plate 16b respectively; the pressure roller 17 is fixed on the sliding seat 18; the sliding seat 18 is installed on the lifting guide rail 19 to guide the vertical movement of the pressure roller 17; the cylinder body of the lifting cylinder 20 is fixedly installed in the bottom area of ​​the frame 12, and the piston rod of the lifting cylinder 20 is connected to the sliding seat 18 through a floating joint; when the lifting cylinder 20 performs telescopic movement, it drives the sliding seat 18 to move up and down along the lifting guide rail 19, thereby driving the pressure roller 17 to rise and fall.

[0023] Furthermore, the wire roller brush 1 and the main shaft 2 are connected by a split-type overlapping connection or an integral set connection; the split-type overlapping connection means that multiple independent wire roller units are sequentially sleeved on the main shaft 2 and fixed by threaded fastening or flange clamping axial clamping mechanism; the integral set connection means that the wire roller brush 1 is a pre-formed cylindrical structure, which is fixed to the outer surface of the main shaft 2 by interference fit or mechanical fastening.

[0024] Furthermore, the motor side plate 16a is provided with a duct interface 26 for connecting the dust collector to extract and filter dust from the air; the bottom of the frame 12 has a base plate 28 for collecting dust, and a dust removal door 27 is also provided on one side of the frame 12 to facilitate cleaning the dust collected on the base plate 28.

[0025] The working principle of this utility model is as follows: A pair of staggered steel wire roller brushes 1 are used to polish multiple parallel steel wires on both sides. The steel wire roller brushes 1 are mounted on the main shaft 2. The rotation of the main shaft 2 achieves axial polishing of the steel wires. A single roller covers nearly 180°, and the combination of the two rollers achieves nearly 360° full coverage. The steel wire roller brushes 1 reciprocate along the axial direction of the main shaft 2. The moving seat 9 on the motor side is driven by the moving cylinder 13 to move along the linear guide rail 11, ensuring even wear of the brush bristles. Pressure rollers 17 are provided on the left and right sides of the main shaft 2. The sliding seat 18 is driven by the lifting cylinder 20 to adjust the clamping force of the main shaft 2 along the lifting guide rail 19. The wire support rollers 14 are fixed to the two side plates (motor side plate 16a, operating side plate 16b) by the spindle 15. The wavy grooves on the wheel surface of the wire support rollers 14 form three-point positioning to prevent the steel wires from moving with the steel wire roller brushes 1. The reciprocating movement; the lifting and lowering adjustment of the pressure roller 17 and the axial reciprocating motion of the wire roller brush 1 are kept synchronized through a mechanical linkage mechanism: the guide rod 24 drives the motor-side adjusting screw 7a and the operating-side synchronous adjusting screw 7b to rotate simultaneously through the bevel gears 23 at both ends, which respectively drive the motor-side moving seat 9 and the operating-side moving seat 10 to move synchronously along the linear guide rail 11; when the handwheel 25 is turned, the rotational motion of the guide rod 24 is converted into the synchronous rotation of the adjusting screw 7a and the synchronous adjusting screw 7b through the corresponding bevel gears 23, and the linkage of the moving seat motor-side moving seat 9 and the operating-side moving seat 10 realizes the balanced adjustment of the clamping force of the main shaft 2; when the lifting cylinder 20 drives the pressure roller 17 to rise and fall, the wave groove of the wire support roller 14 and the axial reciprocating motion of the wire roller brush 1 form a dynamic cooperation to ensure the stable positioning of the wire.
