Description

Technical Field

[0001] The utility model relates to the technical field of looper inlet equipment for steel rolling processing, in particular to a looper inlet equipment for steel rolling processing. Background Art

[0002] Due to design deficiencies, the distance between the entrance guide groove and the roller of the entrance equipment roller assembly spare parts is too far (the entrance bottom plate is not close to the roller). During the rolling process, it is very easy for the red steel elbow to hit the looper roller, resulting in steel piling. This not only poses a safety hazard, but also seriously threatens the smooth progress of production. The rough and medium rolling looper entrance roller equipment assembly function has been lost for many years. The rollers are severely worn and stuck and cannot rotate. During the rolling process, the head and tail of the red steel often rub against the roller, which can easily cause scratches and affect the surface quality of the steel. In order to meet the on-site process requirements and reduce scratches on the surface of the finished product, there is an urgent need for a looper entrance equipment for steel rolling processing to solve the above problems. Utility Model Content

[0024] See also Figure 1-5 , the utility model provides a technical solution: a looper inlet device for steel rolling processing, comprising a roughing and medium rolling looper 1 and a wear-resistant component;

[0025] The wear-resistant component is arranged inside the coarse and medium rolling sleeve 1, and the wear-resistant component includes a ramp part 2, a wear-resistant rotating column 14 and a wear-resistant plate 15. The ramp part 2 is welded to the front side of the coarse and medium rolling sleeve 1, the wear-resistant plate 15 is welded to the inside of the coarse and medium rolling sleeve 1, and the wear-resistant rotating column 14 is rotatably connected to the inside of the wear-resistant plate 15.

[0026] A hanger 4 is welded to the upper end of the roughing and medium rolling sleeve 1, and a hanger hole 3 is opened on the surface of the hanger 4.

[0027] Side plates 6 are welded to both sides of the roughing and medium rolling looper 1 , and two holes 7 are provided on the surfaces of the two side plates 6 .

[0028] Bolts 8 are provided inside the four holes 7 , and the four bolts 8 are in contact with the surface of the corresponding side plate 6 .

[0029] Connectors 11 are welded to the surfaces of the two side panels 6 , threaded holes 10 are formed on the surfaces of the two connectors 11 , and screws 9 are threadedly connected to the inner surfaces of the two threaded holes 10 .

[0030] A support member 12 is provided at the lower end of each of the two side panels 6 . A second threaded hole 13 is provided on the surface of each of the two support members 12 . The interiors of the second threaded holes 13 are connected to the surfaces of the corresponding screws 9 .

[0031] When it is necessary to install the roughing and medium rolling sleeve 1;

[0032] First, the two support members 12 are driven to move by external force, and the movement of the two support members 12 drives the corresponding threaded hole 2 13 to move until it coincides with the position of the corresponding threaded hole 10. Then, the two screws 9 are driven by external tools to be installed into the corresponding threaded hole 10 and threaded hole 2 13.

[0033] Secondly, the hook in the crane is hung on the inside of the hanging hole 3 on the hanging piece 4. Then, the crane is started to drive the hanging hole 3 hung by the hook to move. The movement of the hanging hole 3 drives the hanging piece 4 to move. The movement of the hanging piece 4 drives the rough and medium rolling looper 1 to move to the appropriate position.

[0034] Finally, the roller is inserted into the interior of the rough and medium rolling sleeve 1, and contacts the surface of the wear-resistant rotating column 14 through the upper end of the wear-resistant plate 15. Then, the roller passes through the rough and medium rolling sleeve 1, and then, the two screws 9 are driven by external tools to disassemble and leave the corresponding threaded hole 10 and threaded hole 2 13. Then, the two support members 12 are taken away from the surface of the corresponding connecting member 11.

[0035] Due to years of loss of function, the rollers are severely worn and stuck, and the head and tail of the red steel often rub against the rollers during the rolling process, which easily causes scratches and affects the surface quality of the steel.

[0036] In order to effectively solve the hidden danger of red steel bumping and piling up due to the distance between the roller entrance guide groove and the roller, we decided to improve the roller equipment according to the actual production situation on site:

[0037] Add the wear-resistant plate in front of the roller: The wear-resistant plate in front of the roller has three functions.

[0038] Increase the overall life of the guide groove: In addition to the roller getting stuck offline, the most important impact is the wear of the guide groove bottom plate in front of the roller. The wear at this position will cause the red steel to hit the roller when entering, which will reduce the life of the roller. Therefore, replacing the wear-resistant plate can effectively increase the life cycle of the guide groove and the online operation cycle.

[0039] Wear-resistant plate to prevent collision: the wear-resistant plate is flush with the bottom of the inlet guide groove, and the welding points are polished to prevent red steel from colliding and piling up due to uneven welding points. The outlet side of the wear-resistant plate maintains a distance of 10mm from the roller to ensure that the roller does not interfere with the wear-resistant plate during operation.

[0040] Ensure process quality: Worn guide grooves can cause wear and tear on the workpiece during contact, leading to scratches and abrasions on the surface of the workpiece, affecting the performance of the finished product and even resulting in product rejection. Therefore, investing in and replacing wear-resistant plates can effectively prevent these scratches and abrasions, thereby improving the process quality of the workpiece.

[0041] Improve the life of the roller itself

[0042] The roller material is changed from 45 steel to 42CrMo alloy steel. The improved roller material can extend the life of the roller itself, better delay the wear of the roller, and ensure that the guide groove will not be abnormally worn due to roller wear and sinking during normal rolling, thereby improving the overall life of the guide groove and the online cycle.

[0043] The roller bearing housing has been converted from dry oil lubrication to centralized oil-air lubrication. Dry oil lubrication can easily emulsify over time, leading to poor lubrication and bearing damage. By switching to oil-air lubrication, the bearings are fully lubricated, extending the roller's lifespan.

[0044] The bearings are modified to use larger bearings, which increase the bearing capacity and improve the overall service life of the roller.

[0045] By setting up the wear-resistant rotating column 14 in the wear-resistant component, the roller is changed from direct contact with the roughing and medium rolling sleeve 1 to rolling contact with the surface of the wear-resistant rotating column 14, thereby changing the original sliding friction into rolling friction, which greatly reduces the wear on the roller, thereby extending the service life of the roller and reducing damage to its surface.

[0046] Working principle:

[0047] When it is necessary to install the roughing and medium rolling sleeve 1;

[0048] First, the two support members 12 are driven to move by external force, and the movement of the two support members 12 drives the corresponding threaded hole 2 13 to move until it coincides with the position of the corresponding threaded hole 10. Then, the two screws 9 are driven by external tools to be installed into the corresponding threaded hole 10 and threaded hole 2 13.

[0049] Secondly, the hook in the crane is hung on the inside of the hanging hole 3 on the hanging piece 4. Then, the crane is started to drive the hanging hole 3 hung by the hook to move. The movement of the hanging hole 3 drives the hanging piece 4 to move. The movement of the hanging piece 4 drives the rough and medium rolling looper 1 to move to the appropriate position.

[0050] Finally, the roller is inserted into the interior of the rough and medium rolling sleeve 1, and contacts the surface of the wear-resistant rotating column 14 through the upper end of the wear-resistant plate 15. Then, the roller passes through the rough and medium rolling sleeve 1, and then, the two screws 9 are driven by external tools to disassemble and leave the corresponding threaded hole 10 and threaded hole 2 13. Then, the two support members 12 are taken away from the surface of the corresponding connecting member 11.

[0051] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
