Abstract
Description
Technical Field
[0001] The utility model relates to a high-speed wire laying head equipment. Background Art
[0002] A high-speed wire rod mill generally refers to a wire rod mill with a maximum rolling speed higher than 40 m / s, which is a comprehensive product of metallurgical technology, electric control technology and mechanical manufacturing technology. On a high-speed wire rod production line, after being rolled, the wire rod needs to be laid out in coils by a wire laying head to complete the transformation from a straight wire rod to a coiled wire rod.
[0003] The wire laying head is one of the key equipment in high-speed wire rod production and is also an important bottleneck restricting the further speed increase of high-speed rolling mills. The quality of wire laying directly affects the physical quality of high-speed wire rods. The wire laying head, with its special shape structure and a certain rotational speed, transforms the straight wire rod in high-speed motion into a coil with stable shape and uniform spacing. With the increase in wire rod rolling speed and production output, the requirements for the wire laying head are getting higher and higher. Therefore, in the production of many high-speed wire rod production enterprises, the instability of the laid coils affects product quality and production smoothness.
[0004] Generally, the wire laying head in a high-speed wire rod plant has a horizontal structure and is located between the water-cooling tank and the cold control roller table of the controlled cooling line behind the finishing mill. Figure 1 As shown in the figure, the wire laying head consists of components such as a transmission device, a hollow shaft 5, a wire laying disc 6, a wire laying tube 7, bevel gears 2, 4, etc. The wire laying head is driven by a motor, and the rotation of the hollow shaft 5 is driven by the meshing of a pair of bevel gears 2, 4 in the gearbox. The wire laying tube 7 is installed on the wire laying disc 6, and the wire laying disc 6 is connected to the hollow shaft 5 by bolts.
[0005] When the wire laying head works, the wire rod is sent into the hollow shaft 5 of the wire laying head through the pinch roll in front of the wire laying head by the inlet conduit 3 of the wire laying head. The hollow shaft 5 drives the wire laying disc 6 and the wire laying tube 7 to rotate together, so that the wire rod entering the hollow shaft 5 passes through the rotating wire laying tube 7 and is discharged in a coil along the circumferential tangent direction of the outlet of the wire laying tube 7, and is steadily poured onto the air-cooling roller table, and finally a continuous coil is formed.
[0006] When the wire rod passes through the high-speed rotating wire laying tube, it is subject to the normal pressure of the wall of the wire laying tube 7, sliding friction, the thrust of the finishing mill and the pinch roll, and its own centrifugal force. Under the multiple acting forces, the wire rod gradually bends and deforms along with the shape of the wire laying tube 7, gradually bends from a straight-line motion, and reaches the required curvature at the outlet of the wire laying tube 7 to form a spiral coil, which is discharged in a coil evenly and stably.
[0007] After being rolled, the wire rod is laid out in coils by the wire laying head, transforming the straight wire rod in high-speed motion into a coil with stable shape and uniform spacing, and falling onto the loose coil cooling and transporting roller table.
[0008] In a traditional wire spooling machine, the wire spooling head works together with a wire spooling tube, and the wire is discharged through the wire spooling tube to form a loop. However, since the wire spooling tube is prone to wear, the wire spooling tube needs to be continuously replaced during production, thus affecting the production rhythm. Moreover, each time the wire spooling tube is replaced, the overall balance of the original wire spooling head is damaged, and the dynamic balance of the wire spooling head after replacing the wire spooling tube needs to be redone. Therefore, it is very inconvenient and reduces the production speed and efficiency. Summary of the Utility Model

[0032] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation of the present utility model. In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features.
[0033] To achieve the above object, the present utility model provides a wire spooling machine 100 with a tubeless wire spooling head. As Figure 2 and 3 shown, the wire spooling machine 100 with the tubeless wire spooling head 23 includes a motor, a transmission device, a hollow shaft 22, and a tubeless wire spooling head 23. The motor drives the transmission device, and the transmission device drives the hollow shaft 22 to rotate. The hollow shaft 22 has a front end 221 and a rear end 222. The front end 221 is a straight section, and the rear end 222 is in a flared shape. The tubeless wire spooling head 23 is fixedly connected to the rear end 222 of the hollow shaft 22. The tubeless wire spooling head 23 has a wire spooling head body 24, and at least one spiral groove 241 is provided on the wire spooling head body 24. The wire material is discharged from the spiral groove 241 to form a coil.
[0034] The wire spooling machine 100 replaces the original wire spooling tube and wire spooling disc with the tubeless wire spooling head 23, and solves the technical problem of affecting the production rhythm due to multiple replacements of the wire spooling tube. The wire spooling machine 100 has no excessive wearing parts, and in addition, reduces the number of parts for assembly, and has better overall stability. In addition, the tubeless wire spooling head 23 has good overall symmetry, which reduces the unbalanced vibration during the operation of the equipment and is beneficial to the stable forming of the wire material.
[0035] Specifically, in combination with Figure 4 As shown, in order to adapt to the rear end 222 of the hollow shaft 22, the spinning head body 24 is conical or trumpet-shaped. That is, the top port diameter of the spinning head body 24 is small, and the bottom port diameter is large. A part of the spinning head body 24 extends into the hollow shaft 22, and the spinning head body 24 is fixedly connected to the rear end of the hollow shaft 22 by fixing bolts.
[0036] Preferably, in order to change the wire from a straight line into a coil, the spiral groove 241 on the spinning head body 24 spirals from the top end to the bottom end of the spinning head body 24. The wire gradually bends from a straight line through the spiral groove 241 of the spinning head body 24 and finally forms and spits out at the last turn at the bottom end of the spinning head body 24. In this embodiment, 12 spiral grooves 241 are provided on the spinning head body 24. The spiral grooves 241 on the spinning head body 24 can be used alternately, so this set of tube-free spinning heads 23 can be used online for a long time, with almost no maintenance, increasing the production time and improving the production volume.
[0037] As Figure 2 shown, the tube-free spinning head 23 further includes an inlet guide sleeve 25, and the inlet guide sleeve 25 is fixedly connected to the spinning head body 24 through a fixed shaft. The wire enters from the inlet guide sleeve 25, and the inlet guide sleeve 25 is used to guide the wire into the body of the spinning machine 100.
[0038] In this embodiment, the inlet guide sleeve 25 has several channels. Specifically, the inlet guide sleeve 25 contains 4 channels. The wire enters from the inlet guide sleeve 25 and can be switched to 4 of the spiral grooves 241 of the spinning head body 24 through 4 channels.
[0039] A spinning disk and a cooling sleeve are also fixedly connected to the spinning head body 24. The spinning disk and the cooling sleeve are respectively fixedly connected to the spinning head body 24 by bolts, and a positioning key is installed on the spinning head at the same time. The wire forms a coil and spits out after reaching the spiral groove 241 of the spinning head body 24, and finally forms on the spinning disk and steadily and regularly falls onto the air-cooled roller table.
[0040] In combination with Figure 5 and 6As shown in the figure, the transmission device includes a bevel gear box 21, an input shaft 211, a pair of transmission bevel gears 212, angular contact bearings 213 and oil film bearings 214 disposed in the bevel gear box 21. The hollow shaft 22 is also accommodated in the bevel gear box 21. One end of the hollow shaft 22 is equipped with the angular contact bearings 213, and the other end is equipped with the oil film bearings 214. The motor drives the input shaft 211, and the input shaft 211 drives the hollow shaft 22 through the transmission of the pair of transmission bevel gears 212. The hollow shaft 22 in the coiler 100 is equipped with oil film bearings 214, which have a large load-bearing capacity, good dynamic balance and small vibration. At the same time, compared with the traditional coiler 100, the coiler 100 with the tubeless spinning head 23 has greatly reduced noise during operation.
[0041] As Figure 3 shown in the figure, an inlet conduit 215 is further disposed in the bevel gear box 21, and the inlet conduit 215 corresponds to the inlet guide sleeve 2525. The inlet conduit 215 can be switched every 90 degrees.
[0042] As Figure 2 shown in the figure, a protective cover 26 is further disposed outside the tubeless spinning head 23. The protective cover 26 includes two semi-cylindrical shells 261 that wrap around the spinning head body 24, side plates 262 that are vertically placed on both sides, and a tongue plate 263 between the side plates 262 on both sides. The semi-cylindrical shell 261 located above in the protective cover 26 is driven by a hydraulic steel 27, and the tongue plate 263 is driven by a tongue plate motor 28. The hydraulic steel 27 drives the semi-cylindrical shell 261 to lift and open the protective cover 26, so as to facilitate the repair, maintenance and replacement of the spinning head 23.
[0043] Specific embodiments are applied in the present invention to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope.
