Description

Technical Field

[0001] The invention relates to the technical field of iron and steel metallurgy, and in particular to a vertical high-speed rotating cold-rolled coil feeding device. Background Art

[0002] In the 1980s, my country began to produce ribbed threaded steel bars by cold rolling, using hot-rolled plain carbon steel or low-alloy coils as raw materials. Because its product performance is superior to traditional cold-drawn steel wire, cold rolling technology and production scale have developed rapidly. With the advancement of rolling mill technology and the research and development of new equipment, the cold rolling speed has been continuously improved, from the initial 200 meters / minute to the current 800 meters / minute. The increase in rolling speed has increased production and improved economic benefits, but it has also raised new issues for traditional processes and equipment. From the perspective of most current manufacturers, a bottleneck problem has been exposed, that is, the coil feeding device cannot adapt to the increasing mill speed. The wire is often knotted and broken during feeding, causing the rolling line to stop, seriously affecting production efficiency and economic benefits.

[0003] The coil feeding devices currently used mainly include the following types: feeding stands (storage coils), transfer carts, lifting pallets and coil core racks. This feeding method is to put the raw material coil on the coil core rack, and the wire is pulled up in a spiral shape by the pinch rollers or the rolling mill. The coil cannot be opened automatically, and it is easy to get tangled or broken. This feeding device can still be barely used on a production line of about 800 meters / minute, but the phenomenon of breaking occurs frequently. For rolling speeds greater than 800 meters / minute, this feeding device can no longer match the rolling mill speed. It can be seen that there is an urgent need to solve the common problems of raw material tangling and breaking in cold rolling feeding. Summary of the invention

[0042] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the present invention.

[0043] It should be understood that the orientations or positional relationships indicated by terms such as “horizontal, vertical, top surface, bottom surface, top end, bottom end, both ends, above, below”, etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0044] like Figures 1 to 13As shown, the present invention is a vertical high-speed rotating cold-rolled coil feeding device, which is used in conjunction with a pinch roller or a rolling mill. The power for pulling up the raw material coil comes from the pinch roller or the rolling mill. While the pinch roller or the rolling mill is pulling the wire rod, the feeding device of the present invention provides a rotating motion and a circumferential force for moving the wire rod. Under the combined action of the rolling mill pulling force and the circumferential force of the feeding device of the present invention, the coil is transformed from a ring-shaped coil of the coil into a straight bar state; wherein the feeding device of the present invention comprises a horizontally placed base 3, on which a vertically arranged rotating wire feeding mechanism 2 is installed, and the rotating wire feeding mechanism 2 is located directly above the coil and is wound around The central axis of the coil rotates to lift and transport the coiled wire; the rotating wire feeding mechanism 2 includes a mounting mechanism and a plurality of rotating arms 21 evenly distributed on the mounting mechanism in a circumferential manner. The overall rotation of the rotating wire feeding mechanism 2 drives the plurality of rotating arms 21 to rotate synchronously around the center of the circle formed thereby, and the bottom end wire entry of the rotating arm 21 is located on the rotating circumferential line; a conical cover 1 is also installed at the bottom wire entry of the rotating arm 2 to facilitate the introduction of the wire into the rotating arm 2; in addition, the rotation diameter of the rotating arm 21 is consistent with the diameter of the feeding coil, so that the rotation track of the wire entry ... The trace matches the outer diameter of the feeding coil, ensuring that the wire inlet of the rotating arm 21 is always kept just above the circumferential diameter of the feeding coil, preventing the wire from spiraling when it is lifted and spread, avoiding the wire from being broken due to knotting, and facilitating the complete passage and transportation of the coiled wire; at the same time, by setting up multiple rotating arms 21, they can be interchanged with each other, reducing the wear of the guide rollers. For example, when one rotating arm 21 is offline for maintenance, the other rotating arm 21 can continue to work, which can significantly improve the work efficiency within the specified time; in addition, a driving mechanism 8 is also installed on the base 3, and the driving mechanism 8 and the rotating arm 21 are connected to each other.

Working efficiency; in addition, the guide roller 9 is rotatably installed between the two arc plates 211 and rotates along its own axial direction, and the middle part of the guide roller 9 is also provided with an arc groove for placing the wire and passing it through. Its function is, on the one hand, to provide a limiting guide for the coiled wire when the wire passes through the rotating arm 2, and to reduce the friction resistance.

By setting up the trumpet-shaped cavity, the coiled wire is initially guided and positioned when entering the collecting tube 22, so that the coiled wire becomes vertical and is located on the central axis of the circular tube 23, allowing the coiled wire to pass through the circular tube 23 more smoothly.

[0048] It should also be noted that if Figure 6 As shown, in the present invention, the rotating device 4 includes a chassis 401 fixedly mounted on the base 3, a hollow shaft 402 for mounting the rotating thread-up mechanism 2 is arranged in the chassis 401, the hollow shaft 402 is arranged vertically, and the hollow shaft 402 is rotatably mounted in the chassis 401, and the axial rotation of the rotating thread-up mechanism 2 is driven by the rotation of the hollow shaft 402; in addition, a bevel gear 1 403 is fixedly sleeved on the circumferential outer wall of the hollow shaft 402, and the hollow shaft 402 is driven to rotate synchronously with the bevel gear 1 403 through the rotation; a bevel gear 2 405 meshing with the bevel gear 1 403 is installed in the chassis 401, and the bevel gear 2 405 is rotatably mounted on the chassis 401 through an outer ring cylindrical roller bearing 406 without a retaining edge, and the outer ring cylindrical roller bearing 406 without a retaining edge is provided to bear the radial load of the bevel gear 2 405; Gear 2 405 is connected to driving mechanism 8 through transmission shaft 407, and transmission shaft 407 is driven to rotate by driving mechanism 8, thereby driving bevel gear 2 405 to rotate, and bevel gear 1 403 and bevel gear 1 405 are meshed with each other to realize synchronous rotation of bevel gear 1 403 and bevel gear 2 405. In this specific embodiment, the transmission speed ratio range of bevel gear 1 403 and bevel gear 2 405 is between 2-4; in addition, transmission shaft 407 is horizontally arranged and rotatably mounted on chassis 401 through angular contact bearing 408, and angular contact bearing 408 is arranged to bear the combined radial and axial loads of transmission shaft 407; one end of transmission shaft 407 is fixedly connected to bevel gear 2 405, and the other end is connected to driving mechanism 8 through coupling 7 for transmission, and a coupling protection cover 701 is arranged on the outside of coupling 7 to protect coupling 7.

The double-row tapered roller bearing is used to bear the axial force of the hollow shaft 402; in addition, a grinding gasket 416 is provided between the circumferential side wall of the double-row tapered roller bearing 410 and the inner wall of the chassis 401. By providing the grinding gasket 416, the side clearance generated between the double-row tapered roller bearing 410 and the chassis 401 is adjusted to a suitable size through grinding and thinning of the grinding gasket 416. At this time, the slight axial movement of the bevel gear 403 and the hollow shaft 402 is achieved by the inner ring movement of the inner ring of the cylindrical roller bearing 413 without a flange; an oil retaining ring 411 is also provided below the double-row tapered roller bearing 410.

A key groove 414 for fitting the key 231 is provided on the inner cavity side wall of the hollow shaft 402. The key groove 414 is vertically arranged. By installing the key 231 into the key groove 414, the relative position between the rotating thread mechanism 2 and the hollow shaft 402 is limited. The torque is transmitted by the key 231, so that the hollow shaft 402 drives the rotating thread mechanism 2 to rotate together; and the middle size of the outer cylindrical surface of the round tube 23 is smaller than the end size thereof, so as to reduce the matching surface between the round tube 23 and the rotating device 4, reduce the processing accuracy, and save the manufacturing cost; in addition, a conduit 6 is also installed in the inner cavity of the hollow shaft 402, and the conduit 6 is fixedly installed in the inner cavity of the hollow shaft 402 through the fixing plate 601, A positioning hole 602 for installing a fixing bolt is provided on the fixed plate 601, and the fixing plate 601 is fixed in the inner cavity of the hollow shaft 402 by the fixing bolt; in addition, the conduit 6 is arranged corresponding to the circular tube 23 up and down, the conduit 6 is located directly above the circular tube 23, and the conduit 6 is a conical structure with a larger lower opening and a smaller upper opening, which further facilitates the insertion and passage of the coiled wire; in addition, a bolt hole 415 corresponding to the mounting plate 24 is provided on the bottom end face of the hollow shaft 402, and a bolt adapted to be mounted with the bolt hole 415 is installed on the mounting plate 24. By installing the bolt on the mounting plate 24 into the bolt hole 415, the mounting plate 24 is fixed to the bottom end face of the hollow shaft 402, thereby realizing the fixed installation of the rotating thread-on mechanism 2 in the hollow shaft 402, avoiding its falling off, and enabling the rotating thread-on mechanism 2 to rotate better together with the hollow shaft 402.

[0054] The working process of the device of the present invention:

[0055] During use, the device of the present invention is used in conjunction with a pinch roller or a rolling mill. One end of a vertically placed raw material coil is inserted into the rotating arm 21 from one of the multiple wire inlets of the rotating arm 21, and is successively passed through the rotating arm 21, the guide tube 6 and the guide output mechanism 5, and then installed on the pinch roller or the rolling mill. The pinch roller or the rolling mill provides a pulling force for the raw material coil. While the pinch roller or the rolling mill is pulling the raw material coil, the driving mechanism 8 is started, and the driving mechanism 8 drives the hollow shaft 402 to rotate through the meshing transmission between the gears, thereby causing the hollow shaft 402 to rotate.
