Description

Technical Field

Its main function is to cool and lubricate the rolls during the rolling process to ensure the quality of the metal strip and the normal working life of the rolls. The mill cooling oil spray device can spray the coolant (usually a special cooling oil or water-based liquid) onto the roll surface at a certain pressure and flow rate. This coolant forms a lubricating film on the roll surface, which can not only quickly take away the heat generated by metal deformation, but also reduce the friction between the roll and the metal strip, thereby reducing energy consumption and improving production efficiency; by controlling the amount of oil spray to achieve effective cooling and lubrication of the roll, the mill cooling oil spray device can improve rolling efficiency, extend the service life of the roll, and ensure the surface quality and dimensional accuracy of the final product.

However, the above rolling mill cooling device has the following shortcomings in the specific application process: first, the device cannot flexibly adjust the spray angle of the atomizing oil sprayer, which leads to limited cooling effect, poor performance in dealing with different working conditions and rolling mill parts, and may cause the surface quality of the rolled product to decrease, and cause surface deformation, cracks or other defects, thereby reducing production quality; second, due to the inability to accurately control the direction and angle of the oil spray, the device cannot achieve multi-point directional cooling, and the continuous high temperature working environment will accelerate the aging and wear of the equipment, making the rolling mill more prone to failure and damage, thereby increasing maintenance costs.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] According to an embodiment of the utility model, a rolling mill cooling oil spraying device is provided.

[0024] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-Figure 6 As shown, the rolling mill cooling oil spraying device according to the embodiment of the utility model includes a mounting plate 1, a shifting mechanism 2 is arranged on one side of the mounting plate 1, a driving motor 3 connected to the mounting plate 1 is arranged at one end of the shifting mechanism 2 (in addition, in specific applications, the driving motor 3 is set as a servo motor), a connecting plate 4 is arranged on one side of the middle part of the shifting mechanism 2, a first oil spraying mechanism 5 is arranged on one side of the connecting plate 4, and a second oil spraying mechanism 6 is arranged on the other side of the connecting plate 4, and the first oil spraying mechanism 5 has the same structure as the second oil spraying mechanism 6.

[0025] With the aid of the above-mentioned technical scheme of the utility model, the structure of the utility model is scientific and novel. Through the shifting mechanism 2 and multiple oil injection mechanisms, flexible adjustment of the oil injection angle is achieved, thereby solving the problem that the spray angle cannot be adjusted and the cooling effect is insufficient in the prior art; at the same time, the first oil injection mechanism 5 and the second oil injection mechanism 6 are designed with a multi-angle adjustable structure, so that the oil injection can be carried out at different angles and directions, achieving a cooling effect of specific multi-point and fixed point and direction.

[0026] In one embodiment, for the above-mentioned shifting mechanism 2, the shifting mechanism 2 includes a rotating shaft base 201 arranged at one end of one side of the mounting vertical plate 1, a rotating shaft support seat 202 is arranged at the other end of the mounting vertical plate 1, and one end of the rotating shaft base 201 passes through the rotating shaft support seat 202 and is provided with a driving threaded rod 203 (in addition, in specific applications, the driving threaded rod 203 is respectively connected to the rotating shaft base 201 and the rotating shaft support seat 202 through bearings), and one end of the driving threaded rod 203 is connected to the driving motor. The machine 3 is connected, and a shift block 204 is sleeved on the outer middle part of the driving threaded rod 203, and a support plate 205 matched with the connecting plate 4 is arranged on the top of the shift block 204, and a limiting slide groove 206 is arranged at the bottom of the shift block 204, and a guide rail 207 matched with the limiting slide groove 206 is arranged in the middle part of the top of the mounting vertical plate 1, so that the shift block 204 is driven to move horizontally by the driving threaded rod 203, and the first oil injection mechanism 5 and the second oil injection mechanism 6 are cooperated to perform multi-array and multi-directional cooling on the rolling mill.

[0027] The working principle of the shift mechanism 2 is as follows: first, the shaft base 201 and the shaft support seat 202 are respectively installed at the two ends of the mounting plate 1, providing a fulcrum for rotation, and then the operation of the driving motor 3 can drive the driving threaded rod 203 to rotate. At the same time, a limiting slide groove 206 is provided at the bottom end of the shift block 204, which cooperates with the guide rail 207. This design enables the shift block 204 to move back and forth along the direction of the driving threaded rod 203 under the limitation of the limiting slide groove 206 and the guide rail 207 when the driving motor 3 is started, thereby changing the relative position of the connecting plate 4 and the oil injection mechanism, realizing the adjustment of the oil injection direction, and providing flexibility for the entire rolling mill cooling oil injection device.

[0028] In one embodiment, for the above-mentioned first oil injection mechanism 5, the first oil injection mechanism 5 includes a fixing plate 501 arranged on one side of the connecting plate 4, and fixing blocks 502 are arranged on both sides of the top of the fixing plate 501, and a first connecting arm 503 is penetrated at the top of the fixing block 502, and a first connecting component 504 is sleeved on the outer side of the top of the first connecting arm 503, and a second connecting arm 505 is penetrated at one end of the first connecting component 504, and a second connecting component 506 is sleeved on the outer side of one end of the second connecting arm 505, and the first connecting component 504 has the same structure as the second connecting component 506, and a cooling oil injection component 507 is penetrated at one end of the second connecting component 506, and the first connecting component 504 includes a first sleeve 5041 sleeved on the outer side of the top of the first connecting arm 503 (in addition, in specific applications, the opening directions of the first sleeve 5041 and the second sleeve 5044 are perpendicular), a first card interface 5042 is opened on one side of the first sleeve 5041, and first card interfaces 5042 are arranged on both sides of the first card interface 5042. The first card interface 5042 is provided with a second card block 5043 (in addition, in a specific application, the first card blocks 5043 on both sides of the first card interface 5042 are fixedly connected by bolts), the other side of the first sleeve 5041 is provided with a second sleeve 5044 (in addition, in a specific application, the second sleeve 5044 is fixedly connected to the first sleeve 5041), one side of the second sleeve 5044 is provided with a second card interface 5045, and the second card blocks 5046 are provided on both sides of the second card interface 5045 (in addition, the second card blocks 5046 are fixedly connected to the first sleeve 5041). The second clamping blocks 5046 on both sides of the opening 5045 are fixedly connected by bolts), the cooling oil injection assembly 507 includes a connecting shaft 5071 that passes through one end of the second connecting assembly 506, a cooling oil tank 5072 is provided at one end of the connecting shaft 5071, a solenoid valve 5073 is provided on one side of the cooling oil tank 5072, and a cooling nozzle 5074 is provided at one end of the cooling oil tank 5072, thereby meeting the needs of multi-angle adjustable cooling, realizing flexible adjustment of the injection angle, and ensuring the stability of the injection angle.

[0029] In addition, it should be noted that an oil pump connected to the solenoid valve 5073 is provided on one side of the cooling oil tank 5072, and the oil pump is connected to the cooling nozzle 5074 through an oil pipe. Through the control of the solenoid valve 5073, the oil pump can realize switching operation, thereby controlling the flow of cooling oil in the cooling oil tank 5072. When the solenoid valve 5073 is opened, the oil pump starts to draw cooling oil from the cooling oil tank 5072 and transports it to the cooling nozzle 5074 through the oil pipe to realize cooling spraying of the rolling mill; when the solenoid valve 5073 is closed, the oil pump stops working, and the cooling oil no longer flows out of the cooling oil tank 5072, thereby stopping the oil spray cooling operation of the rolling mill. This is the prior art and will not be elaborated here.

[0030] The working principle of the first fuel injection mechanism 5 is as follows: first, the fixing block 502 fixes the first connecting arm 503 on the top of the fixing plate 501, and the first connecting arm 503 is connected to the second connecting arm 505 through the first connecting component 504. The first connecting arm 503 can rotate in the first sleeve 5041, and the second connecting arm 505 can rotate in the second sleeve 5044. At the same time, since the second connecting component 506 has the same structure as the first connecting component 504, the second connecting arm 505 and the connecting shaft 5071 can rotate in the second connecting component 506, thereby realizing flexible adjustment of the fuel injection angle; when the angle adjustment is completed, the first clamping blocks 5043 on both sides of the first clamping interface 5042 are fixedly connected by bolts, so that the first connecting component 504 and the first connecting arm 503 are firmly fixed together. Similarly, the second clamping blocks 5046 on both sides of the second clamping interface 5045 are also fixedly connected by bolts, and the first connecting component 504 is firmly connected to the second connecting arm 505, thereby ensuring the stability and reliability of the oil injection angle. Finally, the cooling oil in the cooling oil tank 5072 is sprayed out from the cooling nozzle 5074 by starting the solenoid valve 5073, so that the oil injection mechanism can accurately cool various parts of the rolling mill during operation, thereby improving the accuracy of the cooling effect.

[0031] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0032] In actual application, the processed workpiece is fed into the rolling mill from one end of the feeding port 7 and discharged from the discharge roller 8 of the rolling mill. By adjusting the first oil injection mechanism 5 and the second oil injection mechanism 6 (the working principle of the first oil injection mechanism 5 is as described above, and the second oil injection mechanism 6 has the same structure and working principle as the first oil injection mechanism 5), the cooling oil is sprayed from multiple points to the surface of the discharge roller 8 of the rolling mill. The cooling oil forms a lubricating film on the surface of the roller, which can not only reduce the friction between the roller and the metal strip, but also quickly take away the heat generated by the deformation of the metal. Then, the shifting mechanism 2 is driven to move by starting the driving motor 3 (the working principle of the shifting mechanism 2 is as described above), and the oil injection direction is adjusted, thereby realizing the cooling of the inside of the rolling mill in a multi-directional, fixed-point and directional manner.

[0033] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
