Description

Technical Field

[0001] This utility model belongs to the technical field of metal processing equipment, specifically relating to a device for treating oxide scale on the surface of hot-rolled wire rods. Background Technology

[0002] Currently, hot-rolled wire rods require surface oxide scale treatment before drawing. The cleanliness of this oxide scale treatment directly affects the surface brightness of the drawn bar, the drawing speed, and the lifespan of the drawing machine. Current wire rod surface oxide scale treatment devices do not achieve sufficient cleanliness. To improve the cleanliness of the iron oxide scale treatment and promote automated production, it is necessary to design a new device for treating the surface oxide scale of hot-rolled wire rods. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned problems by providing a device for treating the oxide scale on the surface of hot-rolled wire rods, thereby improving the cleanliness of the oxide scale treatment and facilitating subsequent drawing processes of the wire rods.

[0004] This utility model is achieved through the following technical solution:

[0005] A device for treating oxide scale on the surface of hot-rolled wire rod includes a machine base and a frame mounted on the machine base. The frame is characterized by the following components arranged sequentially along the feeding direction of the wire rod: a feed roller, a straightening assembly, a limiting ring, a vertical extrusion assembly, a transverse extrusion assembly, a sandblasting chamber, and a cleaning chamber. The straightening assembly includes a set of rollers arranged vertically, through which the wire rod passes. The limiting ring is a circular ring with a circular cross-section, through which the wire rod passes. The vertical extrusion assembly includes two sets of tensioning wheels, both axially in the front-rear direction, staggered between them. The transverse extrusion assembly has the same structure as the vertical extrusion assembly, but the tensioning wheels are axially vertical. The sandblasting chamber is equipped with several spray guns aimed at the wire rod. The cleaning chamber is equipped with several sets of rotating brush assemblies, each comprising a self-rotating brush mounting base and brushes mounted on the brush mounting base, the brush heads facing the wire rod and cleaning its outer surface.

[0006] Furthermore, the position of each tensioning wheel in the vertical extrusion assembly can be adjusted up, down, left, and right to adapt to the removal of oxide scale from coils of different diameters.

[0007] Furthermore, the vertical extrusion assembly is equipped with 5 tensioning rollers, which are arranged in a trapezoidal shape.

[0008] Furthermore, the sandblasting chamber is equipped with four spray guns, which are evenly arranged at 90-degree intervals along the radial direction of the disk.

[0009] Furthermore, the cleaning chamber is equipped with four sets of rotating brush assemblies, which are evenly arranged at 90-degree intervals along the radial direction of the disk.

[0010] Furthermore, the lower part of the cleaning chamber is provided with a dust removal door, through which oxide scale and other residues in the cleaning chamber are removed.

[0011] The beneficial effects of this utility model are as follows: The device for treating the oxide scale on the surface of hot-rolled wire rod is equipped with a vertical extrusion component, a horizontal extrusion component, a sandblasting chamber, and a cleaning chamber. The extrusion component extrudes and removes the oxide scale from the surface of the wire rod. After sandblasting and cleaning, the oxide scale is effectively cleaned, which helps to improve the drawing speed of subsequent drawing operations and avoids the steel dust on the surface from entering the drawing machine after sandblasting, thus preventing a reduction in the accuracy of the drawing machine.

Detailed Implementation

[0016] The present invention will be further illustrated below with reference to specific examples and accompanying drawings.

[0017] like Figures 1-3As shown, a device for treating oxide scale on the surface of hot-rolled wire rod includes a machine base 1 and a frame 2 mounted on the machine base 1. The frame 2, along the feeding direction of the wire rod 10, is sequentially equipped with a feed roller 3, a straightening assembly 4, a limiting ring 5, a vertical extrusion assembly 6, a horizontal extrusion assembly 7, a sandblasting chamber 8, and a cleaning chamber 9. The straightening assembly 4 includes a set of rollers arranged vertically, through which the wire rod 10 passes. The limiting ring 5 is a circular ring with a circular cross-section, through which the wire rod 10 passes. The vertical extrusion assembly 6 includes two sets of tensioning rollers 61, each with an axial direction in the front-back direction (three on top and two on the bottom), staggered between the two sets. These five tensioning rollers 61 are arranged in a trapezoidal shape, and the position of each tensioning roller 61 can be adjusted vertically, horizontally, and left-right to accommodate the removal of oxide scale from wire rods 10 of different diameters. The transverse extrusion assembly 7 has the same structure as the vertical extrusion assembly 6, but the tensioning wheel 61 is axially vertical. The sandblasting chamber 8 contains four spray guns 81, which are evenly arranged at 90-degree intervals along the radial direction of the disc 10. The spray guns 81 are aimed at the disc 10 for sandblasting. The cleaning chamber 9 contains four sets of rotating brush assemblies 91, which are evenly arranged at 90-degree intervals along the radial direction of the disc 10. Each rotating brush assembly 91 includes a self-rotating brush mounting base 911 and brushes 912 mounted on the brush mounting base 911. The brush heads of the brushes 912 face the disc 10 and clean its outer surface. The cleaning chamber 9 has a dust removal door 92 at its lower part, through which oxide scale and other residues are removed from the cleaning chamber 9.

[0018] The device for treating the oxide scale on the surface of hot-rolled wire rods designed in this utility model, such as... Figure 1 In use, the coil 10 is fed from left to right by the feed roller 3, straightened by the straightening component 4 and the limiting ring 5, and then enters the vertical extrusion component 6 and the horizontal extrusion component 7. The position of the tension wheel 61 of the vertical extrusion component 6 can be adjusted. When adjusted to a suitable position, the oxide scale on the surface of the coil 10 is broken and removed when it is extruded between the tension wheel 61. Similarly, the horizontal extrusion component 7 does the same, extruding the coil 10 from another angle, causing the oxide scale on the surface of the coil 10 to break and remove. Then it enters the sandblasting chamber 8, where the surface of the coil 10 is sandblasted 360 degrees using spray guns 81 at different angles. Finally, it enters the cleaning chamber 9, where the rotating brush 912 cleans the steel dust on the outer surface of the coil 10. After that, it can enter the drawing machine for drawing operations.

Any changes, substitutions, combinations, simplifications, modifications, etc., made by those skilled in the art without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
