Description

Technical Field

[0001] This utility model relates to the field of metal rolling equipment technology, and in particular to a flat plate rolling oil spray beam. Background Technology

[0002] In the rolling production of precision strip, cooling and lubrication during the rolling process are crucial. Multi-roll mills, such as 12-roll mills, have complex roll systems, compact structures, and extremely limited roll gap space within the mill stand. Currently, conventional rolling oil spray beams, which are widely used, have the following prominent problems: First, their overall dimensions are large, making installation difficult within the confined roll system space, and daily maintenance and disassembly are extremely inconvenient; second, their nozzle system has a complex structure, and the oil passages are prone to clogging. Clogging leads to uneven oil spraying, resulting in noticeable color differences on the strip surface, failing to meet the stringent surface quality requirements of high-end products.

[0003] Therefore, there is an urgent need for a rolling oil spray beam that is compact, easy to install and maintain, and can effectively prevent clogging and ensure uniform spraying, in order to meet the application requirements of the confined space of multi-roll mills such as 12-roll mills. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a flat plate type rolled oil spray beam.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses a flat-plate rolling oil spray beam, comprising: an oil supply mechanism, a partition plate inside the oil supply mechanism, a lower spray beam mechanism, and an upper spray beam mechanism, wherein the lower spray beam mechanism and the upper spray beam mechanism are separated by a partition plate. The lower injection beam mechanism includes a base plate and a lower spray plate; the base plate is fixedly connected to the lower part of the oil supply mechanism by bolts, and the upper surface of the base plate is provided with a plurality of oil passage grooves; the lower spray plate is fixedly connected to one end of the base plate by bolts, and the base plate, the partition plate and the lower spray plate together form a lower injection oil passage; the lower injection oil passage communicates with the lower injection oil chamber of the oil supply mechanism through the oil passage grooves; The upper injection beam mechanism includes an upper cover plate and a support plate; the upper cover plate is fixedly connected to the upper part of the oil supply mechanism by bolts, and the lower surface of the upper cover plate is provided with a plurality of oil passage grooves, which together with the partition plate form an upper injection oil passage; the support plate is fixedly connected to the upper cover plate by bolts; the upper injection oil passage is connected to the upper injection oil chamber of the oil supply mechanism through the oil passage grooves.

[0006] As a preferred embodiment of this utility model, the oil supply mechanism is provided with two hooks for suspending and installing the entire spray beam on the rolling mill stand.

[0007] As a preferred embodiment of this utility model, O-rings are provided between the base plate and the oil supply mechanism, and between the upper cover plate and the oil supply mechanism and the base plate for sealing.

[0008] As a preferred technical solution of this utility model, the lower spray plate has a wedge-shaped structure, and multiple holes or gaps for spraying rolling oil are provided between it and the bottom plate and the upper cover plate.

[0009] As a preferred technical solution of this utility model, the lower surface of the lower spray plate is set at a certain angle with the horizontal direction to change the spray angle of the rolling oil.

[0010] As a preferred embodiment of this utility model, the number of oil-through grooves on the upper surface of the base plate is 4 and they are connected to the corresponding lower oil injection chambers, and the number of oil-through grooves on the lower surface of the upper cover plate is 11 and they are connected to the corresponding upper oil injection chambers.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: Adopting a flat, modular design, this device is thin and flat, perfectly suited to the limited installation space inside equipment such as 12-roll mills. Assembly via bolts facilitates easy disassembly, significantly reducing the difficulty and time cost of daily maintenance and cleaning. The oil channels are unobstructed and less prone to clogging. Oil channels are formed by milling grooves into the base and top cover plates, replacing the traditional complex internal drilling and small-diameter nozzle structure. The large cross-section and smooth path of the oil flow channels fundamentally reduce the risk of blockage and ensure the long-term stability of the rolling oil injection. The spray angle of the lower spray beam can be adjusted by replacing the lower spray plates with different angles to achieve the optimal cooling position for the intermediate rolls of the mill. It features reliable sealing, high integration, and a machined oil supply base, reducing leakage points. O-ring seals ensure high reliability. The overall integration of the device facilitates overall hoisting and positioning. Attached Figure Description

Detailed Implementation

[0013] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0014] Example 1: Figure 1-3 This utility model provides a flat-plate rolling oil injection beam, comprising: an oil supply mechanism 7, a partition 6 inside the oil supply mechanism 7, a lower injection beam mechanism, and an upper injection beam mechanism, the lower injection beam mechanism and the upper injection beam mechanism being separated by the partition 6; the oil supply mechanism 7 is the core support and oil source distribution core of the entire injection beam, internally machined with independent and non-interfering upper injection oil chamber 10 and lower injection oil chamber 9, respectively used to supply high-pressure rolling oil to the upper and lower injection beams. The oil supply mechanism 7 is provided with two hooks 4 for suspending and installing the entire injection beam on both sides of the rolling mill stand.

[0015] Furthermore, the lower spray beam mechanism includes a base plate 1 and a lower spray plate 3. The base plate 1 is fixedly connected to the lower part of the oil supply mechanism 7 by bolts. The upper surface of the base plate 1 is provided with multiple oil passage grooves, and 11 oil passage grooves are milled into the upper surface of the base plate 1. An O-ring 8 is provided between the base plate 1 and the oil supply mechanism 7 for sealing. The lower spray plate 3 is fixedly connected to one end of the base plate 1 by bolts. The base plate 1, the partition plate 6, and the lower spray plate 3 together form a lower spray oil channel. The lower spray oil channel is connected to the lower spray oil chamber 9 of the oil supply mechanism 7 through the oil passage grooves. In this way, the oil passage grooves and the corresponding lower spray oil chambers 9, as well as the base plate 1 and the partition plate 6, form a lower spray oil channel. High-pressure rolling oil enters from the lower spray oil chamber 9, is diverted through the oil passage grooves to each lower spray oil channel, and is finally sprayed out evenly from one end of the lower spray plate 3 to cool the intermediate roll. The lower spray plate 3 has a wedge-shaped structure, and multiple holes or gaps for spraying rolling oil are provided between it, the bottom plate 1, and the upper cover plate 5; the lower surface of the lower spray plate 3 is set at a certain angle with the horizontal direction to change the spray angle of the rolling oil. The upper spraying beam mechanism includes an upper cover plate 5 and a support plate 2. The upper cover plate 5 is bolted to the upper part of the oil supply mechanism 7. Multiple oil passage grooves are provided on the lower surface of the upper cover plate 5, forming an upper spraying oil channel together with the partition plate 6. The support plate 2 is bolted to the upper cover plate 5, serving to strengthen the structure. The upper spraying oil channel communicates with the upper spraying oil chamber 10 of the oil supply mechanism 7 through the oil passage grooves. The upper spraying oil chamber 10 communicates with the upper cover plate 5, and the upper cover plate 5 and partition plate 6 form the upper spraying oil channel. High-pressure rolling oil enters from the upper spraying oil chamber 10 and is evenly sprayed out from the outlet of the upper cover plate 5 through the upper spraying oil channel, cooling the work rolls. Crucially, each of the 11 upper oil passages is equipped with an independent control valve inside or outside the oil supply mechanism 7, allowing for individual opening, closing, or flow regulation of each oil passage. This enables zoned cooling of the strip width, achieving precise strip shape control.

[0016] Specifically, first, place the O-ring 8 on the oil supply base 7, install and tighten the base plate 1; install the partition plate 6 and the lower spray plate 3 to form the lower spray beam; then install the upper cover plate 5 and the support plate 2 to form the upper spray beam; finally, weld the hook 4. All connections are made with bolts, allowing the entire device to be quickly disassembled when cleaning or replacing parts is required.

[0017] Compared to conventional spraying systems, this flat-plate rolling oil spraying beam features a more rational nozzle and oil circuit design. The lower spray beam angle can be adjusted by designing different lower spray plates 3 to change the spray angle, and the 11 oil inlet channels of the upper spraying oil channel can individually control the spray beam to meet different strip shape control requirements, greatly improving the surface quality of strip rolling. At the same time, the spray beam's streamlined design allows for easy installation in narrow roll gaps, facilitating quick and easy daily maintenance and significantly reducing maintenance costs.

[0018] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
