Description

Technical Field

[0001] The present invention relates to the technical field of lubrication of steel rolling equipment, and in particular to a double-sided shear main reducer wheel axle support lubrication structure and a state monitoring device thereof. Background Art

[0002] The double-sided shear is the primary trimming equipment in medium and thick plate production lines, and wide and thick plate production lines. It is driven by two main reducers, one on each side. Each main reducer has three output crankshafts connected to the upper tool holder. Shearing subjects the tool holder to heavy radial loads and frequent impact loads, which are borne by the output crankshafts of the main reducer. Existing technology uses rolling bearings to support the output crankshafts. However, rolling bearings have a high failure rate due to frequent radial impact loads, resulting in high manufacturing costs. Furthermore, rolling bearings occupy a large amount of space, which complicates the design space for the shearing machine body. With the development of intelligent manufacturing, smart workshops require full-cycle, real-time monitoring of the operating status of the double-sided shear main reducer. However, existing technology lacks the ability to monitor the operating status of the axle support structure in real time. Any unforeseen bearing damage can cause the production line to suddenly stop, resulting in significant economic losses.

[0003] In order to solve the above problems, it is urgent to develop a structure and device that can better withstand frequent radial impact loads, make the space more compact, reduce manufacturing costs, and at the same time be able to monitor the operating status of the axle support structure in real time.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0043] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0044] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0045] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.

[0055] Furthermore, the first upper circumferential lubrication groove 3-6 and the first lower circumferential lubrication groove 3-7 in the wheel axle lubrication structure are connected to the first internal lubrication groove 3-4, and the end faces of the first sliding sleeve 3, the third sliding sleeve 5 and the sixth sliding sleeve 8 are all provided with end face lubrication grooves, and a number of lubrication holes are distributed in the internal lubrication grooves, which can enable the lubricating oil to quickly penetrate into the friction surface through the connecting grooves, reduce the risk of local dry friction, optimize the flow path of the lubricating oil, and effectively reduce the operating temperature of the sliding sleeve.

[0056] Furthermore, the state monitoring device includes: a high-speed shaft temperature monitoring device 11 and a high-speed shaft vibration monitoring device 12 are respectively provided on the two high-speed shafts 17;

[0057] The first sliding sleeve 3 of the first trimming shear output crankshaft 1-1 and the second trimming shear output crankshaft 1-2 and the fourth sliding sleeve 6 of the shear output crankshaft 2 are each provided with a second output crankshaft temperature monitoring device 14;

[0058] The third sliding sleeve 5 of the first trimming shear output crankshaft 1-1 and the second trimming shear output crankshaft 1-2 and the sixth sliding sleeve 8 of the shear output crankshaft 2 are each provided with a first output crankshaft temperature monitoring device 13;

[0059] Sensors are deployed at key locations on the high-speed shaft 17 and different output crankshafts to ensure there are no blind spots in monitoring. Two types of temperature sensors are set up to meet the monitoring needs of different load areas and improve data reliability.

[0060] Furthermore, the third sliding sleeve 5 is fixed to the upper body through an upper keyway 5-3, and the sixth sliding sleeve 8 is fixed to the lower body through a lower keyway 8-1. The keyway and the flat key cooperate to prevent the sliding sleeve and the body from rotating relative to each other, thereby enhancing structural stability. The key connection ensures that the sliding sleeve is installed in an accurate position and reduces assembly errors.

[0061] Furthermore, all sliding sleeves are equipped with a lubrication monitoring device 16 for real-time monitoring of the lubrication status of the axle support structure. The lubrication monitoring device 16 can monitor parameters such as oil pressure and oil volume of each sliding sleeve in real time to prevent abnormal wear caused by insufficient lubrication.

[0062] Furthermore, the sixth sliding sleeve 8 of the shear output crankshaft 2 is an integral structure, and the first upper circumferential lubrication groove 3-6 and the first lower circumferential lubrication groove 3-7 in its lubrication structure are continuous integral lubrication grooves. The continuous groove design ensures that the lubricating oil flows uninterruptedly in the integral sliding sleeve, avoiding local oil film rupture; the integral structure simplifies the processing technology and improves the matching accuracy with the specific crankshaft.

[0063] Furthermore, the cables of the high-speed shaft temperature monitoring device 11 and the high-speed shaft vibration monitoring device 12 are led out to the outside through the conversion connector 15 to collect operation data in real time. The conversion connector 15 reduces cable interference and ensures high-fidelity transmission of monitoring data. The modular interface design facilitates sensor replacement or upgrading and reduces operation and maintenance complexity.
