Description

Technical Field

[0001] This utility model relates to the field of metal stamping equipment technology, and in particular to a safety protection device for a rolling mill enclosure. Background Technology

[0002] In modern steel industry production, rolling mills, as core equipment, undertake the rolling tasks of metal plates and profiles. The high-speed rotating rolls, transmission components, and flying high-temperature metal debris pose a serious threat to the personal safety of operators. Currently, rolling mills are generally equipped with enclosed covers to isolate dangerous areas and reduce the probability of safety accidents. However, existing protective covers are mostly fixed structures, requiring specialized tools for disassembly during equipment maintenance or troubleshooting. This operation is cumbersome and time-consuming, seriously affecting production efficiency. Furthermore, there are blind spots in the protection between the cover and the outer surface of the rolling mill. Therefore, it is urgent to design a rolling mill enclosed cover safety protection device to solve the above technical problems and improve the safety and reliability of rolling mill operations. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose a rolling mill enclosure safety protection device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A rolling mill enclosure safety protection device includes an outer shell, a buffer seat fixed to the inner wall of the outer shell, a connecting column embedded inside the buffer seat, a buffer spring nested on the outer wall of the connecting column, a contact plate fixed to one end of the connecting column near the middle of the outer shell, an inner frame plate embedded inside the buffer seat, a fixing ring fixed to the top of the inner frame plate, an inner baffle plate embedded inside the inner frame plate, and an operating plate fixed above one end of the inner baffle plate away from the middle of the outer shell.

[0006] Preferably, buffer seats are fixed at the front, rear, left, and right ends of the outer shell, and the connecting column slides horizontally inside the buffer seats.

[0007] Preferably, all four inner baffles are at the same height, and each inner baffle has a storage slot on its upper interior.

[0008] Preferably, the inner opening of the outer shell is provided with a hollow rectangular hidden groove, and the inner frame plate is precisely embedded in the hidden groove.

[0009] Preferably, the cross-sectional area of ​​the fixing ring is the same as the cross-sectional area of ​​the hidden groove, and the fixing ring is made of magnetic material and attracts the outer shell.

[0010] Preferably, the inner frame plate has extension slots at its front, rear, left, and right ends, and the inner baffle is located within the extension slots. The operating plate at the front end of the inner baffle extends from the outer surface of the inner frame plate.

[0011] During use, the distance between the bottom of the outer shell and the bottom of the inner frame plate can be adjusted by pulling the inner frame plate up and down within the outer shell. This allows for adjustment of the protection range of the rolling mill according to actual conditions, facilitating subsequent maintenance and repair. Simultaneously, the inner baffle plate can be pulled up and down within the inner frame plate to ensure it fits snugly against the curved surface of the rolling mill's outer surface. This avoids gaps between the bottom of the inner frame and the rolling mill when the inner frame is tightly against the curved surface, thus achieving complete enclosure protection of the rolling mill's outer surface. This effectively reduces blind spots in the rolling mill's protection, resulting in higher safety performance and better protection. Attached Figure Description

[0017] Legend:

[0018] The outer casing 1, buffer seat 2, connecting column 201, buffer spring 202, contact plate 203, inner frame plate 3, fixing ring 301, inner baffle 302, and operating plate 303 are all included. Detailed Implementation

[0019] Example 1, referring to Figure 1-5 A rolling mill enclosure safety protection device includes an outer shell 1. The outer shell 1 has a buffer seat 2 fixed to its inner wall, a connecting column 201 embedded inside the buffer seat 2, a buffer spring 202 nested on the outer wall of the connecting column 201, a contact plate 203 fixed to one end of the connecting column 201 near the middle of the outer shell 1, an inner frame plate 3 embedded inside the buffer seat 2, a fixing ring 301 fixed to the top of the inner frame plate 3, an inner baffle 302 embedded inside the inner frame plate 3, and an operating plate 303 fixed above one end of the inner baffle 302 away from the middle of the outer shell 1.

[0020] The front, back, left and right ends of the outer shell 1 are all fixed with buffer seats 2, and the connecting column 201 slides horizontally inside the buffer seat 2.

[0021] The inner baffles 302 on the four sides can protect the inner wall of the outer shell 1 from impact forces from different directions, thus increasing the protection range;

[0022] All four inner baffles 302 are at the same height, and each inner baffle 302 has a storage compartment above its interior.

[0023] The storage trough in the inner baffle 302 can collect the debris and some of the lubricating oil thrown out during the rolling mill production process;

[0024] When the contact plate 203 is subjected to force, the contact plate 203 will drive the connecting post 201 to move away from the middle of the outer shell 1, so that the connecting post 201 compresses and deforms the buffer spring 202 in the buffer seat 2, and the force on the contact plate 203 is buffered by the deformation of the buffer spring 202.

[0025] Example 2 differs from Example 1 in that, in this example, the inner opening of the outer shell 1 is provided with a hollow rectangular hidden groove, and the inner frame plate 3 is precisely embedded in the hidden groove;

[0026] The cross-sectional area of ​​the fixing ring 301 is the same as that of the hidden groove. The fixing ring 301 is made of magnetic material and attracts each other with the outer shell 1.

[0027] When the inner frame plate 3 moves the fixing ring 301 up and down in the hidden groove of the outer shell 1, the fixing ring 301 will generate a magnetic force to attract the outer shell 1, thus preventing the inner frame plate 3 from accidentally falling out of the hidden groove of the outer shell 1.

[0028] By pulling the inner frame plate 3 up and down within the outer shell 1, the distance between the bottom of the outer shell 1 and the bottom of the inner frame plate 3 can be adjusted. This allows for adjustment of the protection range of the rolling mill according to actual conditions, making it easier to carry out subsequent maintenance and repair of the rolling mill.

[0029] The inner frame plate 3 has extension slots at the front, back, left and right ends, and the inner baffle 302 is located in the extension slots. The operating plate 303 at the front end of the inner baffle 302 extends from the outer surface of the inner frame plate 3.

[0030] The inner baffle 302 can be moved up and down within the inner frame plate 3 by the operating panel 303, so that the bottom of the inner baffle 302 can be tightly attached to the curved surface of the outer surface of the rolling mill. This avoids the gap between the bottom of the inner frame 3 and the rolling mill when the bottom of the inner frame 3 is tightly attached to the curved surface of the outer surface of the rolling mill. This can achieve full-enclosed protection of the outer surface of the rolling mill, effectively reducing the blind spots in the protection of the rolling mill, resulting in higher safety performance and better protection effect.

[0031] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
