Description

Technical Field

[0002] Steel wire rod generally refers to high-quality steel that is hot-rolled into small-diameter strips.

[0003] At present, the existing steel wire rod bundling and baling process mainly uses vertical or horizontal balers. Fig.12 As shown, in one of the vertical baling machines, a conveyor belt transports the unrolled steel wire rod to the top of the load-bearing bracket, and the steel wire rod is guided by the coil column on the load-bearing bracket and gradually falls layer by layer onto the load-bearing end surface of the load-bearing bracket until the steel wire rod is completely dropped in, and another conveyor belt transports the load-bearing bracket and the steel wire rod coil into the baling machine for compression and bundling, and the lifting equipment lifts the packaged steel wire rod off the load-bearing bracket and moves the steel wire rod to the warehouse.

[0004] Although this type of steel wire rod packaging equipment can be used, due to the high surface requirements of special high-quality steel and the relatively large surface roughness of the steel wire rod, during the compression process of the special high-quality steel wire rod, the outer surface of the steel wire rod is subject to large friction resistance, which can easily produce squeezing points on the surface of the high-quality steel wire rod, resulting in accidents such as breakage of the high-quality steel wire rod during subsequent processing, thereby reducing the production quality of the high-quality steel wire rod.

When the absolute position of the object being described is adjusted, the relative positional relationship may also be adjusted accordingly.

[0022] The present invention provides a method for spraying and preventing crushing of high-quality steel wire rods, the method comprising the following steps: Step 1: adjusting the vertical position of the nozzle for spraying the anti-crushing liquid so that the nozzle is adjusted to a preset position, wherein the preset position is located above the steel wire rod after the steel wire rod forms an unpackaged steel wire rod on the bearing end surface of the baler; Step 2: Adjust the spraying angle of the nozzle so that when the steel wire rod falls around the coil column to form a coil, the nozzle sprays the anti-crushing liquid obliquely upward toward the falling steel wire rod until all the steel wire rods fall to the supporting end surface, completing the first spraying of the anti-crushing liquid; Step 3: Adjust the spraying angle of the nozzle again so that the nozzle sprays the anti-squeeze liquid obliquely downward toward the unpacked steel wire rod on the support end surface; Step 4: While performing step 3, adjust the position of the nozzle in the vertical direction so that the nozzle moves downward gradually. When the nozzle moves close to the bearing end surface, the secondary spraying of the anti-squeeze liquid is completed.

[0023] Step 5: Adjust the distance between the nozzle and the steel wire rod in the horizontal direction so that the nozzle is away from the packaging area of ​​the baler, which is the space occupied by the baler for packaging the steel wire rod.

[0024] Specifically, the present invention can effectively reduce the surface friction of steel wire rods, reduce the packaging pressure and packaging volume of steel wire rods, and avoid the generation of crushing points when the steel wire rods are compressed and packaged by spraying anti-crushing liquid before packaging. By changing the spraying angle of the anti-crushing liquid, the steel wire rods are sprayed twice, so that the upper and lower ends of the steel wire rods are evenly sprayed with the anti-crushing liquid, further improving the uniformity of the anti-crushing liquid spraying and improving the production quality of the steel wire rods. By moving the position between the nozzle and the steel wire rod, the nozzle and other related structures are effectively prevented from interfering with the operation of the packaging machine.

[0025] As an example, see Figures 1 to 3 As shown, the present invention provides a high-quality steel wire rod spraying anti-squeezing device, comprising: The vertical movement module 1 has a vertical movement platform 11 for adjusting the vertical position of the nozzle; An unfolding module, fixedly connected to the vertical moving platform 11, has two sets of symmetrically arranged unfolding components, and the unfolding components are used to adjust the distance between the nozzle and the steel wire rod in the horizontal direction; The spraying module comprises a plurality of spraying units 6 and a driving assembly 7 which are symmetrically arranged on the unfolding assembly with the steel wire rod as the center, the spraying unit 6 is used to connect the nozzle, and the driving assembly 7 is used to adjust the spraying angle of the nozzle; As an example, see Figures 1 to 5 As shown, the expansion components include: The translation module 2 fixedly connected to the vertical moving platform 11 has a translation end 21 that can move toward or away from the vertical moving platform 11; A spraying support 3 fixedly connected to the translation end 21; A rotating bracket 4 is rotatably connected to the spraying bracket 3, and a liquid supply channel 41 is provided in the rotating bracket 4 for providing an anti-squeeze liquid to the nozzle; The telescopic cylinder 5 is rotated, one end of the telescopic cylinder 5 is connected to the rotating bracket 4 by rotation, and the other end of the telescopic cylinder 5 is connected to the spraying bracket 3 by rotation.

[0026] In summary, in this example, the spray module is connected to an external liquid supply device, which is used to provide anti-crushing liquid. The anti-crushing liquid can be a lubricating liquid, such as lubricating oil or a lubricating mixture. In this example, the rotating bracket 4 is driven to rotate by rotating the telescopic cylinder 5, so as to prevent the spray unit 6 from interfering with the transportation of the steel wire rod. The anti-crushing liquid enters the spray component through the liquid supply channel 41, thereby reducing the layout of related pipelines, preventing waste materials such as steel slag from falling and damaging the pipelines, and improving the service life of the spray component.

[0027] Specifically, this example controls the rotation of the spray unit 6 through the driving component 7, so that the anti-crush liquid is evenly sprayed onto the steel wire rod, ensuring the uniformity of the anti-crush liquid spraying. At the same time, two sets of deployment components are used to drive the spray unit 6 to move, avoiding the spray unit 6 from interfering with the packaging and transportation of the steel wire rod.

[0028] As an example, see Figures 1 to 5 As shown, the spray unit 6 includes a spray head base 61 fixedly connected to the rotating bracket 4 by bolts, a connector 62 is fixed on the spray head base 61, a rotatable rotating seat 63 is mounted on the outer wall of the connector 62, and the nozzle includes a spray head 64, the spray head 64 is fixedly connected to the rotating seat 63, a spray flow channel 1 621 penetrating the connector 62 is provided on the connector 62, a spray flow channel 2 631 penetrating the rotating seat 63 is provided in the rotating seat 63, one end of the spray flow channel 1 621 is connected to one end of the spray flow channel 2 631, the other end of the spray flow channel 1 621 is connected to the liquid supply flow channel 41, and the other end of the spray flow channel 2 631 is connected to the spray head 64. Among them, a mounting hole penetrating the spray head base 61 is provided on the spray head base 61, and the connector 62 is inserted into the mounting hole by threaded connection.

[0029] Specifically, this example realizes the diversion and spraying of the anti-crushing liquid through the cooperation of spraying channel 1 621 and spraying channel 2 631, reduces the layout of pipelines, and avoids the problem of deformation of pipelines caused by long-term exposure to high temperature. At the same time, the spraying angle is adjusted by the rotatable rotating seat 63, which further increases the uniformity of the anti-crushing liquid spraying.

[0030] As an example, see Figures 1 to 7 As shown, an arc-shaped end is arranged on the outer wall of the connector 62, and a rotating groove 632 matching the arc-shaped end is provided at one end of the rotating seat 63 facing the connector 62.

The rotating seat 63 includes a rotating body 1 6301 and a rotating body 2 6302 connected by bolts, a rotating groove 1 is provided on the rotating body 1 6301, and a rotating groove 2 that penetrates the rotating body 2 6302 is provided on the rotating body 2 6302, and the rotating groove 1 and the rotating groove 2 are combined to form a rotating groove 632, which is convenient for the disassembly, assembly and maintenance of the rotating seat 63; one end of the spray flow channel 1 621 passes through the arc-shaped end, and a guide groove is provided on the surface of the arc-shaped end.

[0031] Specifically, in this example, the arc-shaped end cooperates with the rotating groove 632 so that the rotating seat 63 can rotate around the center line of the arc-shaped end, thereby ensuring the stability of the rotating seat 63 during rotation. At the same time, through the cooperation between the limiting end face 1 622 and the limiting end face 2 633, the rotating seat 63 is limited to rotate only on the same plane, further increasing the stability of the rotating seat 63 during rotation.

Among them, one end of the arc-shaped slide groove 42 penetrates the rotating bracket 4, and the end of the rotating bracket 4 is fixed with a sealing end block by bolts.

[0035] Specifically, in this example, the output shaft of the driving motor 72 drives the driving gear 73 to rotate, the driving gear 73 drives the movement of the arc-shaped gear ring 71, the arc-shaped gear ring 71 drives the driving unit 74 to work, and the driving unit 74 drives the corresponding components of the spraying unit 6 to work, thereby realizing the adjustment of the spraying angle of each spraying unit 6, and further improving the uniformity of the anti-crushing liquid during spraying.

[0036] As an example, see Figures 1 to 9 As shown, the driving unit 74 includes a No. 1 shaft 741, a No. 2 shaft 742 and a No. 3 shaft 743 which are connected to the rotating bracket 4 in a rotating manner.

The end of the wire rope 68 is fixedly connected to the driven arm 745 through the guidance of the guide wheel 66. A No. 2 spur gear 7421 and a No. 2 bevel gear 7422 are fixed to the outer wall of the No. 2 shaft 742 by a key connection. The No. 1 spur gear 744 is meshed with the No. 2 spur gear 7421. The center line of the No. 3 shaft 743 is arranged vertically. A driven gear 747 and a No. 3 bevel gear 748 are fixed to the outer wall of the No. 3 shaft 743. The driving gear 73 is meshed with the driven gear 747, and the No. 2 bevel gear 7422 is meshed with the No. 3 bevel gear 748. Among them, the first axis 741 is arranged above the second axis 742, and the third axis 743 is arranged on the side of the first axis 741 and the second axis 742. The rotating bracket 4 is provided with a support ear, and the first axis 741, the second axis 742 and the third axis 743 are inserted into the corresponding support ears by rotating.

[0037] Specifically, in this example, the third shaft 743 is rotated by the rotation of the driven gear 747, the third shaft 743 drives the third bevel gear 748 to rotate, the third bevel gear 748 drives the second bevel gear 7422 to rotate, the second bevel gear 7422 drives the second shaft 742 to rotate, the second shaft 742 drives the second spur gear 7421 to rotate, the second spur gear 7421 drives the first spur gear 744 to rotate, the first spur gear 744 drives the first shaft 741 to rotate, the first shaft 741 drives the driven arm 745 to rotate, the driven arm 745 drives the wire rope 68 to rotate, the wire rope 68 is guided by the guide wheel 66 to drive the rotating column 1 65 to move, the rotating column 1 65 drives the rotating seat 63 to rotate, the rotating seat 63 drives the spray head 64 to move, thereby realizing the adjustment of the spraying angle and ensuring the adjustment accuracy of the spraying angle.
