Description

Technical Field

[0001] This utility model belongs to the technical field of copper strip processing equipment, and in particular relates to a copper strip rolling equipment. Background Technology

[0002] In the copper strip rolling process, the frictional characteristics between the rolls and the strip directly affect the rolling force, strip surface quality, and roll life. Traditional rolling equipment typically uses spray devices with fixed angles and positions, which are difficult to adapt to the dynamically changing frictional requirements during rolling, leading to the following problems:

[0003] 1. Uneven lubricating film thickness: A fixed spray angle can easily cause uneven distribution of lubricant on the roll surface. In some areas, insufficient lubrication can lead to dry friction, which accelerates roll wear and causes defects on the strip surface.

[0004] 2. Excessive lubricant and waste: In order to avoid local dry friction, traditional equipment often compensates by excessive spraying, which leads to increased lubricant consumption. In addition, excessive liquid is easy to splash onto the outside of the equipment, increasing energy consumption and recycling costs. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a copper strip rolling equipment that realizes adaptive spray control of lubricating fluid, ensures spray effect, improves the utilization effect of lubricating fluid, and reduces energy consumption costs.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a copper strip rolling equipment, including a rolling mill stand, rolling rolls mounted on the rolling mill stand, and a lubrication system. The lubrication system includes a spray module for spraying lubricating fluid, an oil film thickness detection element for detecting the oil film on the product surface, and a control module. The spray module includes a mounting frame mounted on the rolling mill stand, a rotatable spray frame mounted on the mounting frame, a spray pipe mounted on the spray frame, and a drive cylinder for driving the spray frame to rotate. One end of the drive cylinder is hinged to the mounting frame, and the other end is hinged to the spray frame. As the drive cylinder extends and retracts, the relative angle between the spray frame and the copper strip feeding direction can be changed. One end of the spray pipe is externally connected to a liquid inlet pipe, and the other end is provided with a spray head. The control module is signal-connected to the oil film thickness detection element and the drive cylinder.

[0007] Preferably, the spray frame is provided with multiple mounting holes, which are evenly distributed along the width of the spray frame. The spray pipe is composed of multiple spray pipes arranged in parallel, and the spray pipes are fixedly inserted into the corresponding mounting holes and connected in parallel with each other.

[0008] Preferably, the number of mounting holes is greater than the number of spray pipes, and an appropriate number of spray pipes can be selected and installed in the corresponding mounting holes according to the actual spray volume requirements.

[0009] Preferably, the spray pipe includes a main pipe and a plurality of branch pipes connected to the main pipe. The branch pipes are arranged in parallel and all communicate with the main pipe, and are arranged in a fan shape from the main pipe as the center to both sides.

[0010] Preferably, at least a portion of the inlet pipe is fixedly installed on the mounting frame, and its outlet end is connected to the spray pipe via a telescopic pipe.

[0011] Preferably, the expansion joint is a corrugated pipe.

[0012] Preferably, the spray pipe is equipped with multiple sets of electrically controlled regulating valves and electrically controlled flow meters, each set of electrically controlled regulating valves and electrically controlled flow meters corresponding to a set of spray heads, and the electrically controlled regulating valves and electrically controlled flow meters are signal connected to the control module.

[0013] The technical effects of this invention are as follows: by dynamically adjusting the angle, the oil film thickness can be controlled more accurately, thus improving the uniformity of lubrication; at the same time, by dynamically adjusting the flow rate, on-demand supply can be achieved, thus optimizing the utilization rate of lubricant.

[0021] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0022] like Figures 1-5 As shown, a copper strip rolling equipment includes a rolling mill stand 1, on which rolling rolls 11 are provided. The rolling rolls 11 are arranged in groups and driven by a rolling adjustment drive assembly. The rolling mill stand, rolling rolls 11 and adjustment drive assembly are all existing technologies. The adjustment drive assembly can be an existing drive motor for driving the rotation of the rolling rolls 11 and a lifting cylinder for driving the lifting and lowering of the bearing seats on both sides of the rolling rolls 11.

[0023] Specifically, the rolling mill stand 1 is equipped with a lubrication system 2, which includes a spray module 21, an oil film thickness detection element 22, and a control module 23. The control module 23 is existing technology and is a commonly used PLC. The oil film thickness detection element 22 is an existing infrared spectral oil film thickness gauge, which is installed above the roll exit side to detect the oil film thickness in real time. It is connected to the control module 23 by signal.

[0024] Specifically, the spray module 21 includes a mounting frame 31, a spray frame 32, a spray pipe 33, and a drive cylinder 36. The mounting frame 31 is fixed to the feed end of the rolling base frame, and two are symmetrically arranged vertically. Each mounting frame 31 is hinged to a spray frame 32, and a drive frame 38 is fixed to the spray frame 32. One end of the drive cylinder 36 is hinged to the mounting frame 31, and the other end is hinged to the drive frame 38. As the drive cylinder 36 extends and retracts, the spray frame 32 can rotate relative to the mounting frame 31. The spray frame 32 is inclined relative to the copper strip.

[0025] Specifically, one end of the spray pipe 33 is connected to an inlet pipe 34, and the other end is equipped with a spray head. The inlet pipe 34 is fixedly installed inside the mounting frame 31. Its inlet end is connected to an external liquid storage device, and its outlet end is connected to the spray pipe 33 through a telescopic pipe 37, which is a corrugated pipe.

[0026] Furthermore, such as Figures 2-5As shown, in some embodiments, the spray pipe 33 is composed of multiple parallel spray pipes. Multiple mounting holes 321 are provided on both the front and rear side frames of the spray frame 32. The mounting holes 321 on the front and rear side frames are grouped together in a one-to-one correspondence. The mounting holes 321 are evenly distributed along the width direction of the spray frame 32. According to the actual spray volume requirements, an appropriate number of spray pipes are selected and installed in the corresponding groups of mounting holes 321. The spacing between the spray pipes during actual installation can also be selected according to the spray volume requirements. The number of groups of mounting holes 321 is generally greater than the actual number of spray pipes installed. Each spray pipe... Each end of the pipe is equipped with a spray head, and each of them is individually connected in series with a set of electrically controlled regulating valves and electrically controlled flow meters. The electrically controlled regulating valves and electrically controlled flow meters are existing technologies and are both connected to the control module 23 via signals. The liquid outlet of the liquid inlet pipe 34 has multiple liquid outlets arranged in parallel. The positions of the liquid outlets correspond to the positions of the mounting holes 321. Some liquid outlets are connected to the corresponding spray pipes through the telescopic pipe 37, and the remaining liquid outlets are blocked by plugs. The telescopic pipe 37 is generally connected to the spray pipes and the liquid inlet pipe 34 through a threaded connection structure. This threaded connection structure is an existing internal and external thread structure commonly used in the pipeline field.

[0027] like Figure 6 In other embodiments, the spray pipe 33 includes a main pipe 331 and multiple branch pipes 332. The main pipe 331 is connected to the liquid inlet pipe 34 through a telescopic pipe 37. One end of each branch pipe 332 is connected to the main pipe 331 and is arranged in parallel. The branch pipes 332 are arranged in a fan-shaped distribution structure that extends symmetrically to both sides from the main pipe 331 as the center. Spray heads are provided at the ends of each branch pipe 332. Each branch pipe 332 is equipped with a set of electrically controlled regulating valves and electrically controlled flow meters. The electrically controlled regulating valves and electrically controlled flow meters are both existing technologies and are both signal-connected to the control module 23.

[0028] The specific implementation of this utility model is as follows: the oil film thickness detection element 22 monitors the oil film thickness on the copper strip in real time, and adjusts the spray frame 32 accordingly to adjust the spray angle. At the same time, the flow rate of each electronically controlled regulating valve is adjusted separately, and the spray volume of each spray head is finely adjusted separately to ensure more accurate control of oil film thickness and improve lubrication uniformity.

[0029] The above description is only a specific embodiment of the present utility model, but the structural features of the present utility model are not limited thereto. The present utility model can be used in similar products. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
