Description

Technical Field

[0001] This utility model relates to the field of steelmaking technology, specifically to a coupling for a high-speed wire rod mill. Background Technology

[0002] High-speed wire rod finishing mills typically consist of multiple stands that work together to complete their tasks. They are mostly cantilevered roll ring stands, arranged alternately horizontally and vertically. Vertical loopers are installed between the stands to achieve tension-free rolling. In daily maintenance, the cone box needs to be replaced. Replacing the cone box is inconvenient and the alignment is quite cumbersome. Since the finishing mill is a high-speed rotating machine, each time the cone box is replaced, the coaxiality of both ends of the cone box needs to be aligned. Each cone box replacement alignment takes 3 to 4 hours. Moreover, because something needs to be placed under the cone box, the cone box must be removed and hoisted down before operation. After alignment, the cone box needs to be hoisted down to install the coupling, which increases the probability of misalignment of the cone box. The existing structure uses couplings.

[0003] The main reason for this problem is that the external gear ring of the coupling is too long and the overall size is not easy to adjust, making it impossible to reselect the size of the internal and external gear rings. Utility Model Content

[0004] This utility model addresses the above problems by providing a coupling for a high-speed wire rod mill.

[0005] The technical solution adopted is a coupling for a high-speed wire rod mill, including a first internal gear ring, a second internal gear ring, a driving external gear ring, and a driven external gear ring. One side of the first internal gear ring is detachably connected to one side of the second internal gear ring. The driving external gear ring is located on the other side of the first internal gear ring, and the driven external gear ring is located on the other side of the second internal gear ring.

[0006] Furthermore, one side of the first internal gear ring is provided with a first mounting protrusion, and one side of the second internal gear ring is provided with a second mounting protrusion, and the first mounting protrusion and the second mounting protrusion can fit together.

[0007] Furthermore, the diameter of the first mounting protrusion is the same as the diameter of the second mounting protrusion.

[0008] Furthermore, the first mounting protrusion and the second mounting protrusion are detachably connected by hexagonal bolts passing through the first mounting protrusion and the second mounting protrusion.

[0009] Furthermore, one end of the active external gear ring is provided with a threaded structure, and is detachably connected to the other side of the first internal gear ring through the threaded structure;

[0010] One end of the driven external gear ring is provided with a threaded structure, and is detachably connected to the other side of the second internal gear ring through the threaded structure.

[0011] Furthermore, a first limiting bolt passes through the body of the first internal gear ring, and the first limiting bolt can pass through the driving external gear ring;

[0012] A second limiting bolt passes through the body of the second internal gear ring, and the second limiting bolt can pass through the driven external gear ring.

[0013] Furthermore, a first limiting hole is provided on the inner wall of the second internal gear ring, and a second limiting hole is provided on the driven external gear ring, wherein the second limiting bolt can pass through the first limiting hole and the second limiting hole.

[0014] The beneficial effects of this utility model are:

[0015] 1. By changing the original unified internal gear ring structure to two detachable structures, the size of the internal gear ring can be adjusted according to the actual size of the cone box, shortening the alignment time and improving the overall work efficiency.

[0016] 2. A special connection method for the internal and external gear rings is adopted, which can significantly improve the tightness of the connection between the two. Attached Figure Description

It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0024] In this embodiment, as Figure 1 As shown, a coupling for a high-speed wire rod mill includes a first internal gear ring 1, a second internal gear ring 2, a driving external gear ring 3, and a driven external gear ring 4. One side of the first internal gear ring 1 is detachably connected to one side of the second internal gear ring 2. The driving external gear ring 3 is located on the other side of the first internal gear ring 1, and the driven external gear ring 4 is located on the other side of the second internal gear ring 2.

[0025] The purpose of this design is to change the original unified internal gear ring structure into two detachable structures, so that the size of the internal gear ring can be adjusted according to the actual size of the cone box, shortening the alignment time and improving the overall work efficiency.

[0026] Meanwhile, in a specific implementation, a specific example is provided in which the first internal gear ring and the second internal gear ring are detachably connected. One side of the first internal gear ring 1 is provided with a first mounting protrusion 5, and one side of the second internal gear ring 2 is provided with a second mounting protrusion 6, and the first mounting protrusion 5 and the second mounting protrusion 6 can fit together.

[0027] Meanwhile, the diameter of the first mounting protrusion 5 is the same as the diameter of the second mounting protrusion 6.

[0028] Furthermore, the first mounting protrusion 5 and the second mounting protrusion 6 are detachably connected by hexagonal bolts 9 passing through the first mounting protrusion 5 and the second mounting protrusion 6.

[0029] The purpose of this design is to increase the contact area when the two internal gear rings are connected by the protrusion, and at the same time, to allow for the selection of internal gear rings of various sizes for connection.

[0030] In this embodiment, as Figure 2 and Figure 3 As shown, one end of the active external gear ring 3 is provided with a threaded structure, and is detachably connected to the other side of the first internal gear ring 1 through the threaded structure;

[0031] One end of the driven external gear ring 4 is provided with a threaded structure, and is detachably connected to the other side of the second internal gear ring 2 through the threaded structure.

[0034] The inner wall of the second internal gear ring 2 is provided with a first limiting hole 10, and the driven external gear ring 4 is provided with a second limiting hole 11. The second limiting bolt 8 can pass through the first limiting hole 10 and the second limiting hole 11.

[0035] The purpose of this design is to use a special structure for the connection between the internal and external gear rings, which can greatly improve the tightness of the connection between the two. When connecting, first select an external gear ring of appropriate size, and then screw it into one end of the internal gear ring through the thread structure. When you observe through the through hole on the internal gear ring that it is about to be tightened and the first limit hole and the second limit hole are aligned, insert the limit bolt to provide a radial force, which can greatly reduce the chance of the external gear ring coming off.

[0036] Meanwhile, since the active external gear ring and the driven external gear ring have similar structures and the same connection structure as the internal gear ring, the driven external gear ring is selected for description in this embodiment. Those skilled in the art can refer to this to set up the active external gear ring.

[0037] Taking one of the applicant's processing lines as an example, after the modification using the technical solution provided in this application, the time for replacing the finishing mill cone box is significantly shortened, resulting in significant benefits. The estimated indirect economic benefits are: 700h / month × 12 months × 0.43% × 90t / h = 3250 tons / year × average profit (500 yuan) / ton = 1.625 million yuan / year.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
