Description

Technical Field

[0001] This utility model relates to the field of metal sheet rolling technology, specifically a metal sheet rolling anti-deviation guide device. Background Technology

[0002] In the field of sheet metal processing, rolling is the core process for achieving sheet forming and thickness control: hot rolling mills apply pressure to metal billets to cause plastic deformation, while conveyor rollers transfer the rolled sheet to subsequent processes. To ensure continuous rolling operations and product precision, the sheet conveying trajectory must be precisely controlled. Therefore, the industry commonly installs anti-deviation structures on the conveying path in front of the hot rolling mill. These structures use mechanical limiters to assist in guidance and adapt to the needs of continuous rolling. Such devices have become key supporting equipment for ensuring the stability of the production line.

[0003] However, during continuous rolling of metal sheets, anti-deviation devices are required to push and straighten the sheets multiple times. But the width of the sheet increases after rolling, which may cause the anti-deviation device to over-compress the wide sheet after rolling, resulting in a large degree of deformation. Furthermore, the existing anti-deviation devices have a fixed length. When dealing with long metal sheets, the fixed-length limiting structure cannot effectively constrain the front or rear of the sheet. The sheet is still prone to deviating from the limit range during transportation, which affects the continuity of the rolling process. Utility Model Content

[0004] The purpose of this invention is to provide a guide device for preventing deviation in the rolling of metal sheets, in order to solve the problems mentioned in the background art, such as the potential for excessive compression of wide sheets after rolling and the fixed length of existing anti-deviation devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A guide device for preventing deviation in sheet metal rolling includes a conveyor roller and an anti-deviation component; The anti-deviation component includes a mounting base and two sliding frames on both sides. A limit frame is slidably installed inside the sliding frame. A pressure sensor is installed inside the sliding frame. An extension frame is installed in front of the limit frame.

[0006] In a preferred embodiment of this utility model, a hot rolling mill is provided behind the conveying roller, and the mounting base is located in front of the hot rolling mill.

[0007] In a preferred embodiment of this utility model, mounting plates are provided on both sides of the top of the mounting base, and the sliding bracket is slidably mounted on the inner side of the mounting plates.

[0008] In a preferred embodiment of this utility model, an electro-hydraulic rod is provided inside the mounting plate, and the telescopic end of the electro-hydraulic rod is connected to a sliding frame.

[0009] In a preferred embodiment of this utility model, a protrusion is provided inside the limiting frame, and the protrusion is in contact with the detection surface of the pressure sensor.

[0010] In a preferred embodiment of this utility model, a hinge is provided at the top of the connection side of the limiting frame and the extension frame, and the limiting frame and the extension frame are connected by the hinge.

[0011] In a preferred embodiment of this utility model, an installation port is provided on the rear outer side of the extension frame, and a bolt is installed inside the installation port for easy assembly and disassembly.

[0012] In a preferred embodiment of this utility model, a screw hole is provided on the outer front side of the limiting frame, and the bolt is threadedly connected to the screw hole.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0014] Beneficial effects: After the metal sheet is rolled once, it is moved forward by the conveyor rollers to the space between the two limit frames. At this time, the sliding frame and the limit frames are pushed by the electric hydraulic rods on both sides, thereby straightening the metal sheet and preventing it from deviating. When straightening the metal sheet, the extrusion pressure is transmitted to the pressure sensor through the limit frame and the protrusion, thereby detecting the pressure. When the pressure reaches a certain value, the extrusion stops, thus preventing the metal sheet from deforming too much. When the metal sheet is long, the limit frame can be extended by folding the extension frame forward, thereby expanding the limiting range of the metal sheet and ensuring that the longer metal sheet can still maintain accurate guidance during the conveying process and avoid deviation.

[0015] The above description is merely an overview of the technical solution of this utility model.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please refer to Figures 1-4 This utility model discloses a metal sheet rolling anti-deviation guiding device, including a conveying roller 1 and an anti-deviation component. A hot rolling mill 11 is arranged behind the conveying roller 1. The hot rolling mill 11 and the conveying roller 1 are the main rolling structures used to roll metal sheets, which is the existing structure. The hot rolling mill 11 and the conveying roller 1 are controlled by the existing main control system. The anti-deviation component is used to prevent the metal sheet from deviating during continuous rolling. The anti-deviation component includes a mounting base 12, which is an installation structure used to install other structures. The mounting base 12 is located in front of the hot rolling mill 11.

[0020] The anti-deviation component also includes two sliding frames 2. Limit frames 22 are slidably installed inside the sliding frames 2. Mounting plates 13 are installed on both sides of the top of the mounting base 12. The sliding frames 2 are slidably installed inside the mounting plates 13. An electro-hydraulic rod 14 is installed inside the mounting plate 13. The electro-hydraulic rod 14 can be a high-temperature resistant electro-hydraulic push rod of model DYTZ-500 / 110-X. The telescopic end of the electro-hydraulic rod 14 is connected to the sliding frame 2. After the metal sheet is rolled once, the conveying roller 1 drives the metal sheet forward, i.e., it moves between the two limit frames 22. At this time, the... The two electric hydraulic rods 14 push the sliding frame 2 and the limiting frame 22, thereby straightening the metal sheet through the limiting frame 22 to prevent it from shifting. This operation is repeated in subsequent rolling cycles. A PLC controller can be set on one side of the mounting plate 13. The PLC controller can be a Siemens S7-1200 series 6ES7214-1AG40-0XB0 model PLC, or it can be set in other suitable locations. It is used to debug and control the electric hydraulic rods 14 and the pressure sensor 21. Debugging in advance is a conventional technical means for those skilled in the art.

[0021] A pressure sensor 21 is installed inside the sliding frame 2. The pressure sensor 21 is electrically connected to the electric hydraulic rod 14. The pressure sensor 21 can be an OMGAPX409-015G5V model pressure sensor. An extension frame 3 is installed in front of the limiting frame 22. A protrusion 23 is installed inside the limiting frame 22. The protrusion 23 contacts the detection surface of the pressure sensor 21. Through the structural limitation of the limiting frame 22 and the sliding frame 2 itself, the sliding distance of the limiting frame 22 is limited. That is, when the metal sheet is straightened, the extrusion force is transmitted to the pressure sensor 21 through the limiting frame 22 and the protrusion 23 to detect the pressure. When the pressure reaches a certain value, the extrusion stops, thereby avoiding excessive deformation of the metal sheet.

[0022] A hinge 31 is provided on the top of the side connecting the limiting frame 22 and the extension frame 3. The hinge 31 is made of high-temperature resistant alloy, such as 304 stainless steel. The limiting frame 22 and the extension frame 3 are connected by the hinge 31, so that the extension frame 3 can be folded in front of the limiting frame 22. An installation port 33 is provided on the outer rear side of the extension frame 3. A bolt 34 is installed inside the installation port 33 for disassembly and assembly. A screw 32 is provided on the outer front side of the limiting frame 22. The bolt 34 and the screw 32 are threadedly connected. When the extension frame 3 is folded in front of the limiting frame 22, the screw 32 aligns with the installation port 33. The bolt 34 can then pass through the installation port 33 and be tightened in the screw 32 to fix the extension frame 3. Under normal circumstances, the extension frame 3 is folded above the limiting frame 22. When the metal plate is long, the limiting frame 22 can be extended by folding the extension frame 3 forward, thereby expanding the limiting range of the metal plate and ensuring that the long metal plate can still maintain accurate guidance during the conveying process and avoid deviation.

[0023] The working principle of this utility model is as follows: After the metal sheet is rolled once, the conveying roller 1 drives the metal sheet forward, that is, it moves between the two limiting frames 22. At this time, the electric hydraulic rods 14 on both sides push the sliding frame 2 and the limiting frame 22, thereby straightening the metal sheet through the limiting frame 22 to prevent it from deviating. When straightening the metal sheet, the extrusion pressure is transmitted to the pressure sensor 21 through the limiting frame 22 and the protrusion 23 to detect the pressure. When the pressure reaches a certain value, the extrusion stops, thereby preventing the metal sheet from deforming too much. When the metal sheet is long, the extension frame 3 is folded forward to extend the limiting frame 22, thereby expanding the limiting range of the metal sheet and ensuring that the long metal sheet can still maintain accurate guidance during the conveying process and avoid deviation.

[0024] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
