Description

Technical Field

[0001] The utility model relates to the technical field of cold rolling mills, and in particular to an automatic purging device for a rolling mill. Background Art

[0002] A cold rolling mill is an important device in the metal processing industry, mainly used for further processing hot-rolled metal materials to obtain thinner, flatter plates or strips with better surface quality. Cold rolling is carried out at room temperature or close to room temperature, different from hot rolling which is carried out above the recrystallization temperature of the material.

[0003] At present, when large aluminum processing enterprises produce and roll aluminum plates and strips, rolling oil adheres to the plate surface and edges. The rolling oil cannot be effectively removed, which will cause excessive oil on the plate surface, resulting in plate surface quality problems, making it impossible to guarantee the plate surface quality, and will also cause oil on the edges. When the plate passes through the edge gap of the roll, a large amount of rolling oil will be carried out and thrown from the edge to the rolling mill trench, thus causing a large amount of energy consumption loss. Therefore, an automatic purging device for a rolling mill is needed to remove the rolling oil on the plate. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an automatic purging device for a rolling mill to solve the problem that rolling oil adheres to the plate surface and edges and cannot be effectively removed.

[0005] To achieve the above purpose, the utility model provides an automatic purging device for a rolling mill, including a purging beam assembly. The purging beam assembly is arranged on the thickness measuring frame of the rolling mill, and the cross beam on the thickness measuring frame of the rolling mill serves as the thickness measuring anti-collision beam of the purging beam assembly;

[0006] The purging beam assembly includes a purging beam. Both ends of the purging beam are fixed to the thickness measuring anti-collision beam through pipe clamps and strengthening seats;

[0007] The strengthening seat is welded to the pipe clamp and fixedly arranged on the pressing plates at both ends of the thickness measuring anti-collision beam. The purging beam is fixedly connected to the pipe clamp;

[0008] A plurality of through holes are evenly spaced on the purging beam. Inner threaded pipes are connected in the through holes. The inner threaded pipes are fixedly connected to the purging beam. Sector nozzles are connected to the ends of the inner threaded pipes. The sector nozzles are arranged at an angle of 30° with respect to the plate outlet direction;

[0009] Anti-collision wedges are arranged on the thickness measuring anti-collision beam. The anti-collision wedges are arranged with a small angle inclination towards the plate outlet direction and are arranged opposite to the sector nozzles.

[0010] Preferably, in the above automatic purging device for a rolling mill, the through holes on the purging beam are evenly spaced 12 cm apart.

[0011] Preferably, in the above-mentioned automatic purging device for a rolling mill, a plurality of sector nozzles are provided, including a direct-blow nozzle disposed in the middle of the purging beam and inclined-blow nozzles located on both sides of the direct-blow nozzle and inclined respectively to both sides. The inclination angle of the inclined-blow nozzles is 15°.

[0012] Preferably, in the above-mentioned automatic purging device for a rolling mill, the purging beam is connected to the outlet valve station of the rolling mill, and the outlet valve station provides a gas source for the purging beam.

[0013] Preferably, in the above-mentioned automatic purging device for a rolling mill, a PLC control system and a solenoid valve are provided. The solenoid valve is disposed in the outlet valve station, and the PLC control system controls the solenoid valve to realize automatic purging.

[0014] Therefore, the automatic purging device for a rolling mill with the above structure according to the present invention is applicable to purging in aluminum sheet rolling mills in the industrial industry, and has advantages such as eliminating oil on the plate surface, improving product quality and efficiency. The sector nozzles disposed on the pressure purging beam blow obliquely from the middle to both sides of the plate surface, and the solenoid valve is connected to the PLC control system to realize automatic purging during the threading of the sheet. An anti-collision wedge is installed on the thickness measurement and anti-collision beam to protect the sector nozzles disposed on the purging beam from being damaged by the thick material being processed.

[0018] The technical solution of the present invention will be further described below with reference to the drawings and embodiments.

[0020] Refer to the attached Figure 1-2 As shown, this application provides an automatic purging device for a rolling mill, including a purging beam assembly. The purging beam assembly is arranged on the thickness measuring frame of the rolling mill, and the cross beam on the thickness measuring frame of the rolling mill serves as the thickness measuring anti-collision beam 2 of the purging beam assembly;

[0021] The purging beam assembly includes a purging beam 1. Both ends of the purging beam 1 are fixed to the thickness measuring anti-collision beam 2 through pipe clamps and reinforcing seats 3;

[0022] The reinforcing seat 3 is welded to the pipe clamp and is fixedly arranged on the pressing plates 4 at both ends of the thickness measuring anti-collision beam 2. The purging beam 1 is fixedly connected to the pipe clamp;

[0023] A plurality of through holes are evenly spaced on the purging beam 1. An internally threaded pipe 5 is connected in the through hole. The internally threaded pipe 5 is fixedly connected to the purging beam 1. The end of the internally threaded pipe 5 is connected to a sector nozzle 6. The sector nozzle 6 is arranged at an angle of 30° with respect to the plate outlet direction;

[0024] An anti-collision wedge 7 is arranged on the thickness measuring anti-collision beam 2. The anti-collision wedge 7 is arranged to be inclined at a small angle in the direction of the plate outlet and is arranged opposite to the sector nozzle 6.

[0025] Specifically, installing the anti-collision wedge 7 on the thickness measuring anti-collision beam 2 can protect the sector nozzle 6 arranged on the purging beam 1 from being damaged by the thick material being processed.

[0026] To further optimize the above technical solution, the through holes on the purging beam 1 are evenly spaced 12 cm apart.

[0027] To further optimize the above technical solution, a plurality of sector nozzles 6 are provided, including a direct blowing nozzle arranged in the middle of the purging beam and inclined blowing nozzles located on both sides of the direct blowing nozzle and inclined to both sides respectively. The inclination angle of the inclined blowing nozzles is 15°.

[0028] Specifically, the sector nozzles 6 are arranged relative to the traveling direction of the sheet, and are inclined to both sides, enabling oblique blowing. During the traveling process of the sheet, the rolling oil on the sheet is blown off, so as not to affect the quality of the sheet and cause problems on the sheet surface.

[0029] To further optimize the above technical solution, the purging beam 1 is connected to the outlet valve station of the rolling mill, and the outlet valve station provides a gas source for the purging beam.

[0030] It should be noted that connecting to the outlet valve station does not require connecting to an external gas source, simplifying the device structure.

[0031] To further optimize the above technical solution, a PLC control system and solenoid valves are provided. The solenoid valves are arranged at the outlet valve station, and the PLC control system controls the solenoid valves to achieve automatic purging.

[0032] Specifically, compressed air is led from the outlet valve station to the purging beam 1. Due to safety zone control, manual opening is rather cumbersome. Therefore, an automatic rolling mill threading program is added through the PLC, realizing an automatic purging mode, greatly improving the problem of oil on the sheet surface and also improving the problem of layer misalignment caused by oil. The automatic control of the solenoid valves can be achieved through the PLC control system.

[0033] Therefore, the automatic purging device of the rolling mill with the above structure of the present utility model is applicable to the purging of aluminum sheet rolling mills in the industrial industry, and has advantages such as eliminating oil on the sheet surface, improving product quality and efficiency. The sector nozzles arranged on the purging beam blow obliquely from the middle to both sides of the sheet surface, and the solenoid valves are connected to the PLC control system to achieve automatic purging during sheet threading. Anti-collision wedges are installed on the thickness measuring and anti-collision beam to protect the sector nozzles arranged on the purging beam from being damaged by thick materials during processing. The automatic purging device with the above structure of the present utility model utilizes the compressed air purging function to reduce the oil on the surface of the rolled sheet, providing effective sheet surface quality for aluminum sheet products.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present utility model, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present utility model.
