Description

Technical Field

[0001] This utility model relates to the field of cold rolling equipment, and in particular to an adjustable edge oil blowing device for cold rolling. Background Technology

[0002] In aluminum alloy production, the purging device is particularly important. Currently, the sheet purging device installed on cold rolling mills mainly consists of upper and lower purging nozzles and edge purging nozzles. The edge purging nozzles are generally installed on the front and rear frame chassis and crossbeams of the sheet thickness measuring instrument. At this time, the edge purging device cannot be moved, and adjustments can only be made manually to clean the rolling fluid from the edges of the strip. Existing edge purging devices have the following drawbacks: 1. When the width of the cold-rolled strip is different, the range of the edge purging device needs to be frequently adjusted, which increases labor intensity. Moreover, if the purging range of the purging device is not adjusted properly, the oil stains on the sheet surface cannot be cleaned; 2. The upper and lower edge purging are not synchronized, causing the oil stains on the lower edge of the sheet to splash back onto the upper surface under the action of purging, forming an oil film, resulting in annealing oil spots during annealing. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable edge blowing device for cold rolling, which solves the problem that the edge blowing device in the prior art is immovable and can only be adjusted manually to adjust the range of the edge blowing nozzle.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses an adjustable edge oil blowing device for cold rolling, comprising a housing, a first fixed frame, and a second fixed frame. A transmission screw is rotatably mounted inside the housing, and a first slider and a second slider capable of moving left and right are mounted on the transmission screw. The first slider is fixedly mounted with a first fixed frame, which has a lower left air outlet and an upper left air pipe, both with an upper left air outlet. The second slider is fixedly mounted with a second fixed frame, which has a lower right air outlet and an upper right air pipe, both with an upper right air outlet.

[0006] Furthermore, the upper right air inlet and the upper right air pipe are connected by an upper right universal adjustment mechanism; the upper left air inlet and the upper left air pipe are connected by an upper left universal adjustment mechanism.

[0007] Furthermore, the upper left and upper right air inlets have the same structure, both being flat.

[0008] Furthermore, the lower right air inlet and the lower left air inlet have the same structure, both being inclined elongated holes.

[0009] Furthermore, the first slider is threadedly engaged with the transmission screw, and the second slider is threadedly engaged with the transmission screw.

[0010] Furthermore, the transmission screw is driven by an electric motor, which is electrically connected to the controller.

[0011] Furthermore, a lower purge air inlet pipe connected to the lower left and lower right air inlets is provided on the right end face of the housing, and an upper purge air inlet pipe connected to the upper left and upper right air inlets is provided on the right end face of the housing.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This utility model's adjustable edge oil blowing device for cold-rolled aluminum strips can automatically adjust the blowing width via a bidirectional variable frequency motor. The upper air inlet of this device can blow oil onto any position on the edge of the strip via a universal adjustment mechanism. This adjustable edge oil blowing device can automatically adjust, improving production efficiency, reducing labor intensity, and ensuring the surface quality of the aluminum alloy strip. This adjustable edge oil blowing device can automatically adjust the width range and blow oil onto the upper and lower surfaces simultaneously, more effectively cleaning the oil stains on the edges of the upper and lower surfaces. This effectively prevents the quality problem of annealing oil spots forming on the strip edges after annealing, allowing the strip surface to undergo annealing treatment without cleaning.

Detailed Implementation

[0019] like Figures 1 to 3 As shown, an adjustable edge oil blowing device for cold rolling includes a housing 1, a first fixed frame 3, and a second fixed frame 4. This device is installed on the exit side of the cold rolling mill, between the plate thickness measuring instrument and the plate shape roll. Its main function is to blow away the oil stains on the upper and lower surfaces of the strip, so that the surface of the aluminum alloy strip is clean and free of oil stains, achieving a cleaning-free state.

[0020] The housing 1 is rotatably equipped with a transmission screw 2, which is driven by a motor 13. The motor 13 is a bidirectional frequency converter motor and is electrically connected to the controller 14.

The upper left air pipe 10 has an upper left air outlet 17. The upper left air outlet 17 and the lower left air outlet 15 are on the same vertical line.

[0022] A second fixing frame 4 is fixedly mounted on the second slider 6. The second fixing frame 4 has a lower right air outlet 16 and an upper right air pipe 9, which has an upper right air outlet 18. The upper right air outlet 18 and the lower right air outlet 16 are on the same vertical line.

[0029] After checking that all devices are installed in place, turn on the power and manually control the button to adjust the purging width. At this time, the two purging devices should move in opposite directions at the same time.

[0030] After adjusting the purge nozzle to the appropriate position, open the compressed air valve bracket and adjust the gas pressure to 0.20 MPa;

[0031] Check if the four nozzles are operating normally. Under normal circumstances, the lower nozzles on both sides should sweep inwards and the upper nozzles on both sides should sweep outwards.
