Technical Field
[0001] The utility model relates to the technical field of cold rolling mills, in particular to a cold rolling mill purge device. Background Art
[0002] During the rolling process of metal materials in the cold rolling mill, appropriate rolling oil should be used between the rolls and the workpiece to avoid damage to the surface of the workpiece, to ensure the life of the rolls, and to achieve the purpose of lubrication and cooling. However, the workpiece will carry a certain amount of rolling oil after passing through the rolls. The rolling oil on the workpiece needs to be cleaned to avoid the rolling oil from having an adverse effect on subsequent processes.
[0003] However, during cold rolling, the workpiece will not only be contaminated with rolling oil when it comes into contact with the cold rolling rollers, but some of the cold rolling oil will also be thrown onto the workpiece during the rotation of the cold rolling rollers. This will cause excessive rolling oil on the surface of the workpiece, making it more difficult to remove it with the subsequent cold rolling mill purge device, and increasing the difficulty of purge. Utility Model Content
[0004] The purpose of the utility model is to provide a cold rolling mill purge device to solve the problems raised in the above background technology.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] A cold rolling mill purging device comprises a cold rolling mill body, an upper oil connecting tank and a lower oil connecting tank. The upper and lower oil connecting tanks are respectively provided at the front of the upper and lower rollers of the cold rolling mill body. Both sides of the upper and lower oil connecting tanks are fixedly connected to the cold rolling mill body. Two vertical plates are installed at the rear of the upper and lower rollers of the cold rolling mill body. An upper purge frame and a lower purge frame are symmetrically arranged between the two vertical plates. The upper purge frame and the lower purge frame both comprise a V-shaped purge pipe, a nozzle and a mounting plate. Mounting plates are installed at both ends of the V-shaped purge pipe. The mounting plates are fixed to the vertical plates by screws. A plurality of nozzles are installed at the bottom of the V-shaped purge pipe.
[0007] As a further solution of the present invention: the opening of the V-shaped purge pipe faces the moving direction of the rolled piece.

[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] 1. The utility model provides an upper oil receiving groove and a lower oil receiving groove in front of the upper and lower rollers of the cold rolling mill body respectively. The upper oil receiving groove and the lower oil receiving groove can block the rolling oil splashed from the rollers during the rotation of the rollers, thereby greatly reducing the probability of the rolling oil on the rollers splashing onto the rolled piece, which is beneficial to keeping the surface of the rolled piece clean and reducing the difficulty of subsequent blowing of the rolled piece.
[0013] 2. The utility model sets an upper purge frame and a lower purge frame, both of which are V-shaped frames, and the bottom of the purge frame is equipped with nozzles arranged in a V shape, so that the cold rolling oil on the rolled piece can be blown from the middle to both sides, making the blowing more comprehensive and the blowing effect better.
[0014] 3. The upper oil tank and the lower oil tank of the utility model both have the function of storing oil, and an oil collecting box is also provided at the bottom of the blowing rack, so that the cold rolling oil thrown out by the rollers and the cold rolling oil blown away by the blowing rack can be collected for easy reuse, thereby achieving the purpose of saving resources.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1-2 In the embodiment of the present invention, a cold rolling mill purge device includes a cold rolling mill body 1, an upper oil tank 2 and a lower oil tank 3. The upper and lower rolling rollers of the cold rolling mill body 1 are respectively provided with an upper oil tank 2 and a lower oil tank 3. Both sides of the upper oil tank 2 and the lower oil tank 3 are fixedly connected to the cold rolling mill body 1. One side of the upper oil tank 2 and the lower oil tank 3 are respectively connected to the upper oil outlet pipe 4 and the lower oil outlet pipe 5 installed on the cold rolling mill body 1. The upper oil outlet pipe 4 and the lower oil outlet pipe 5 are both installed with a first oil outlet valve 6. The first oil outlet valve 6 is used to control the on and off of the upper oil outlet pipe 4 and the lower oil outlet pipe 5 to control the discharge of rolling oil.
[0021] See also Figure 1-3 Two vertical plates 7 are installed at the rear of the upper and lower rollers of the cold rolling mill body 1. An upper purge frame 8 and a lower purge frame 9 are symmetrically arranged between the two vertical plates 7. The upper purge frame 8 and the lower purge frame 9 both include a V-shaped purge pipe 16, a nozzle 17 and a mounting plate 18. Mounting plates 18 are installed at both ends of the V-shaped purge pipe 16. The mounting plate 18 is fixed to the vertical plate 7 by screws. A plurality of nozzles 17 are installed at the bottom of the V-shaped purge pipe 16. The opening of the V-shaped purge pipe 16 faces the moving direction of the rolled piece. This design allows the rolled piece to be gradually purged from the middle to both sides, making the purge more thorough and achieving better purge effect.
[0022] An oil receiving box 13 is installed on the inner side of the two vertical plates 7. An oil discharge pipe 14 is installed at the bottom of the oil receiving box 13. A second oil outlet valve 15 is installed on the oil discharge pipe 14. The second oil outlet valve 15 is used to control the opening and closing of the oil discharge pipe 14 and control the discharge of rolling oil.
[0023] The upper part of the upper purge rack 8 and the lower part of the lower purge rack 9 are respectively connected to the upper purge rack connecting pipe 10 and the lower purge rack connecting pipe 11. The upper purge rack connecting pipe 10 and the lower purge rack connecting pipe 11 are connected and a flange port 12 is opened at the connecting position. The flange port 12 is externally connected to the compressed air pipeline.
[0024] The working principle of this utility model is:
[0025] During use, when the workpiece passes through the upper and lower rollers of the cold rolling mill body 1 for cold rolling, the rotation of the rollers will throw the cold rolling oil on its surface forward. At this time, the upper oil receiving tank 2 and the lower oil receiving tank 3 installed in front of the rollers will intercept the cold rolling oil flying to the upper and lower surfaces of the workpiece, and the cold rolling oil will be collected in the upper oil receiving tank 2 and the lower oil receiving tank 3. The personnel only needs to open the first oil outlet valve 6 to discharge the rolling oil in the upper oil receiving tank 2 and the lower oil receiving tank 3 through the oil outlet pipe. After rolling, the external compressed air pipeline supplies compressed air to the upper purge rack 8 and the lower purge rack 9. The compressed air is sprayed through the nozzles 17 on the upper purge rack 8 to purge the rolling oil on the upper surface of the workpiece from the middle to both sides step by step. At the same time, the nozzles 17 on the lower purge rack 9 purge the rolling oil on the lower surface of the workpiece from the middle to both sides step by step. The purged cold rolling oil falls into the oil receiving box 13 and is finally discharged from the oil unloading pipe 14 through the second oil outlet valve 15.
[0026] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
