Description

Technical Field

[0001] This application belongs to the field of steel wire processing equipment, and specifically relates to a device for removing impurities from the surface of steel wire. Background Technology

[0002] After production, steel wire inevitably accumulates many oxidized impurities on its surface due to the manufacturing process. These impurities cannot participate in the production of materials and need to be removed in advance. Currently, the mainstream removal equipment mainly uses steel wire impurity removal machines. These machines bend the steel wire by winding a wheel assembly. Because the impurities are brittle, they will automatically break off. However, in this type of impurity removal machine, the wheel assembly is small, and the contact area between the steel wire and the wheel assembly is small. As a result, the impurities can easily bury the steel wire. Therefore, it is necessary to solve the problem of the small contact area between the steel wire and the wheel assembly and the incomplete removal of impurities.

[0003] Chinese Patent Application No. 201822057131.X discloses a device for removing the oxide layer from reinforcing bars. The device includes a vertical plate with a long groove machined in the middle and guide portions protruding on both sides of the groove. A central shaft passes through the groove and has a fitting portion in the middle that matches the guide portions. The inner side of the central shaft is connected to a height-adjusting screw to form a screw-slider structure. A zigzag wheel is installed at the outer end of the central shaft. A roller cutter assembly is installed above the vertical plate and symmetrically positioned on both sides of the central shaft. The reinforcing bar bends during winding between the roller cutter assembly and the zigzag wheel, causing some of the oxide layer to peel off. The height of the zigzag wheel is adjustable. The device is suitable for removing the oxide layer from reinforcing bars of various materials. While bending the reinforcing bar, the roller cutter shaft further cuts the oxide layer on the outer surface of the reinforcing bar. The device has a more compact structure and excellent oxide layer removal effect. The second cutter holder is detachable for easy replacement of the roller cutter shaft.

[0004] This type of oxide scale removal mechanism has an overly concentrated structure and small wheels. By using a few concentrated rollers to rub the surface of the steel wire, the surface contact ratio is low, resulting in poor oxide scale removal. Utility Model Content

[0005] In order to solve the problem of small contact area between steel wire and roller in the prior art mentioned in the background, this application provides a steel wire surface impurity removal device.

[0006] This application provides a device for removing impurities from the surface of steel wire, including: Front support unit; The rear support unit is arranged in a straight line opposite to the front support unit. The friction wheel used to remove impurities from the surface of the steel wire has at least one friction wheel that can be rotated on the front support and the rear support. The installation height of each friction wheel is different so that the steel wire forms at least one bend after winding around the wheel surface of each friction wheel. The friction wheel includes a wheel axle and movable extrusion rollers. Wheel discs extending radially are formed on the inner sides of both ends of the wheel axle. Multiple movable extrusion rollers are circumferentially distributed and movably mounted between the wheel discs. The top surface of the movable extrusion rollers away from the wheel axle is an upwardly convex elliptical shape. A gap is left between each movable extrusion roller and the adjacent movable extrusion rollers to allow the movable extrusion rollers to swing freely.

[0007] Furthermore, the number of friction wheels is three, with friction wheels rotatably mounted at the lower part of the front support, at the end of the rear support near the front support, and at the bottom of the rear support.

[0008] Furthermore, the aforementioned front support is a support column, and a fixed pulley is fitted at the top of the front support.

[0009] Furthermore, a column located between the front support section and the rear support section is equipped with a second fixed pulley at its top.

[0010] Furthermore, multiple movable shafts are evenly distributed along the circumference of the wheel axle between the discs. The movable extrusion roller has shaft holes along its length for clearance fitting with the movable shafts. The movable extrusion roller is movably fitted onto the movable shaft through the shaft holes.

[0011] Furthermore, the bottom end of the movable extrusion roller near the axle is a gradually converging triangular shape.

[0012] Furthermore, it also includes a winding machine, which is arranged in a straight line opposite to the rear support unit and the front support unit.

[0013] This application includes at least one of the following beneficial technical effects: 1. Compared to the shortcomings of the prior art, such as "small wheel set and small contact area", the movable extrusion roller... The elliptical top surface increases the fit with the curved surface of the steel wire, and the multi-roller circumferential layout forms a continuous dynamic wrap. When the steel wire is bent, the movable extrusion roller can adapt to the curvature of the steel wire and swing freely, increasing the contact area by about 40%-60%, solving the problem of impurities not being completely removed, and improving the removal rate of surface oxide shell.

[0014] 2. In the background technology, only the brittle fracture of bending during a single contact is relied upon. However, the gap between the movable extrusion rollers and the triangular bottom end ensure that the bottom end of the movable extrusion roller will not interfere during the swinging process. Therefore, the movable extrusion roller can swing freely. During the contact with the steel wire, each movable extrusion roller will also swing with the force, which is equivalent to scraping the surface of the steel wire, further increasing the contact area and giving the movable extrusion roller the ability to swing with the movement of the steel wire, thereby increasing the ability to remove oxides.

[0015] 3. The three friction wheels form multiple bending points, making the oxide layer easier to remove under torsional deformation, improving the impurity removal rate, inducing composite deformation of the steel wire, and making the steel wire impurity removal rate even higher.

[0021] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0022] Example 1

[0023] A device for removing impurities from the surface of steel wire is provided, comprising a front support 2 and a rear support 4, the rear support 4 being arranged linearly opposite to the front support 2; both the front support 2 and the rear support 4 are fixed to the ground as supports to provide support, the front support 2 being higher than the rear support 4, and the steel wire can pass through the top of the front support 2 to form a coiled structure; a friction wheel 1 is also provided for peeling impurities from the surface of the steel wire. The friction wheel 1 can be a smooth wheel with grooves, so that the oxides on the surface of the steel wire can be removed by bending. However, this removal method is inefficient and can only meet the surface oxide removal requirements of low standards.

[0024] Alternatively, the friction wheel 1 can have another structural form, which includes a wheel axle 1a and movable extrusion rollers 1d. Wheel disks 1c extending radially are formed on the inner sides of both ends of the wheel axle 1a. The movable extrusion rollers 1d are multiple and circumferentially distributed and are movably mounted between the wheel disks 1c. The top surface of the movable extrusion rollers 1d away from the wheel axle 1a is an upwardly raised elliptical shape 1da. A gap is left between each movable extrusion roller 1d and the adjacent movable extrusion roller 1d to allow the movable extrusion roller 1d to swing freely.

[0025] The top surface of the movable extrusion roller 1d is elliptical, which increases the contact area with the steel wire. Furthermore, since there is a free swing gap between the movable extrusion rollers 1d, the movable extrusion rollers 1d can swing back and forth during the rotation process, which further enhances the removal rate of surface oxide impurities.

[0026] To enhance the bending performance of the steel wire, a multi-bending structure was designed. For example, at least one friction wheel 1 is rotatably mounted on the front support part 2 and the rear support part 4. The two friction wheels 1 are installed at different heights so that the steel wire can form at least one bend after winding around the wheel surface of each friction wheel 1. The oxide scale at the bend can be removed through this bend, but the removal efficiency is not high.

[0027] Example 2

[0028] This application requests the disclosure of a steel wire surface impurity removal device, which includes the contents of Embodiment 1, but differs from Embodiment 1 in that: the number of friction wheels 1 is three, and friction wheels 1 are rotatably mounted on the lower part of the front support part 2, the end of the rear support part 4 near the front support part 2, and the lower part of the rear support part 4.

[0029] The friction wheel 1 also includes a plurality of movable shafts 1f evenly distributed along the circumference of the wheel shaft 1a between the wheel discs 1c. The movable extrusion roller 1d has a shaft hole along its length for clearance fit with the movable shaft 1f. The movable extrusion roller 1d is clearance fit on the movable shaft 1f through the shaft hole. The movable extrusion roller 1d can swing on the movable shaft 1f. The movable extrusion roller 1d is a strip-shaped body.

[0030] The top surface of the movable extrusion roller 1d away from the movable shaft 1f is elliptical, and the bottom end of the movable extrusion roller 1d near the wheel shaft 1a is a gradually converging triangular shape 1db. The top edge of the triangular 1db portion coincides with or exceeds the bisector of the width direction of the movable extrusion roller 1d.

[0031] To meet the requirements of a three-bend design, the front support section 2 is a support column 5, which is fixed to the ground. A fixed pulley 3 is mounted on the top of the front support section 2 via a bearing 1b. The fixed pulley 3 is fixedly mounted on the top of the front support section 2 via a shaft with bearings 1b at both ends. A middle column 5 is located between the front support section 2 and the rear support section 4, and a second fixed pulley is mounted on the top of the column 5. The height of the middle column 5 is lower than the height of the support column 5, and higher than the height of the rear support section 4. The rear support 4 is a frame. A friction wheel 1 is mounted on the lower part of the front support 2. The axle 1a of the friction wheel 1 has bearing seats 1b connected to both ends. These bearing seats 1b are fixedly connected to the front support 2. The rear support 4 is also equipped with a friction wheel 1 near the front support 2. The axle 1a of the friction wheel 1 has bearing seats 1b connected to both ends. These bearing seats 1b are fixedly connected to the rear support 4 near the front support 2. A rotatable friction wheel 1 is also mounted below the rear support 4. A fixed base on the ground is located below the rear support 4. The axle 1a of the friction wheel 1 is fixed to the base via bearing seats 1b. Thus, steel wires can pass over the fixed pulley 3 at the top of the front support 2. The friction wheel 1 of the part passes through the second fixed pulley at the top of the central column 5, then through the friction wheel 1 below the base, and finally through the friction wheel 1 fitted at the end of the rear support part 4 near the front support part 2. Finally, it is wound and wound by the winding machine 6. The winding machine 6 is arranged in a straight line opposite to the rear support part 4 and the front support part 2. The winding machine 6 has a drive motor, a reducer, and an I-beam wheel that is poweredly connected to the reducer. The drive motor drives the reducer. After the wheel set inside the reducer is driven, the output shaft of the reducer maintains a low speed and high torque output. The I-beam wheel and the output shaft of the reducer are poweredly connected through a coupling. After being wound, the steel wire will form at least three bends and be stored on the I-beam wheel. Of course, the winding machine 6 can also be replaced by a thinning machine to thin the steel wire to meet subsequent needs.

[0032] During use, the steel wire is typically coiled on an I-beam reel. The steel wire released from the initial I-beam reel sequentially passes over the fixed pulley 3 at the top of the front support section 2, the friction wheel 1 at the bottom of the front support section 2, the second fixed pulley at the top of the middle column 5, the friction wheel 1 on the base below the rear support section 4, and the friction wheel 1 at the end of the rear support section 4 near the front support section 2, and is finally wound up by the I-beam reel of the winding machine 6. This path forces the steel wire to undergo three forced bends in different directions at the three friction wheels 1. During this process, the movable extrusion roller 1d of the friction wheel 1 closely adheres to the curved surface of the steel wire with its elliptical top surface 1da, and under the lateral force generated by the bending of the steel wire, it adaptively oscillates around the movable shaft 1f through the shaft hole. The triangular bottom design of its 1db ensures that adjacent extrusion rollers 1d do not interfere with each other during oscillation. The synergistic effect of multi-roller dynamic wrapping and oscillating scraping significantly increases the effective contact area and interaction strength between the steel wire and the friction wheels, allowing the oxide layer on the surface of the steel wire to be fully broken and removed under multiple torsional deformations.
