Description

Technical Field

[0001] The utility model relates to thick aluminum strip rolling equipment tooling, more specifically, to a roll gap blowing device. Background Art

[0002] The main working parts and tools on the rolling mill that cause continuous plastic deformation of metal. The roller is mainly composed of three parts: the roller body, the roller neck and the shaft head. The roller body is the middle part of the roller that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. The roller neck is installed in the bearing and transmits the rolling force to the frame through the bearing seat and the pressing device. The transmission end shaft head is connected to the gear seat through the connecting shaft to transmit the rotational torque of the motor to the roller.

[0003] At present, when the rolling mill produces thick materials above 2.0, its edge is covered with rolling oil, and as the temperature drops in winter, the rolling oil is more obvious, which increases the cleaning cost of the lower anti-winding plate of the equipment frame in the next process. The structure of the lower anti-winding plate is as follows: Figure 1 shown. Utility Model Content

[0004] In view of the defects existing in the prior art, the purpose of the utility model is to provide a roll gap blowing device, which can reduce the rolling oil on the edge of thick strips of more than 2.0 and reduce the cleaning cost of subsequent processes.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A roller gap blowing device comprises a lower anti-winding plate;

[0007] An extended section is provided at the lower portion of the lower anti-winding plate;

[0008] A toothed section is provided in the middle of the bottom edge of the extended section, and the rest of the bottom edge of the extended section is a straight line section;

[0009] A purge nozzle is provided at the intersection of the toothed segment and the straight segment;

[0010] The purge air nozzle is connected to an external air source through a purge pipe;

[0011] The purge pipeline is provided with a solenoid valve, and the solenoid valve establishes a communication connection with the production system.

[0012] Preferably, the purge pipe is fixed on the induction heating base plate.

[0013] Preferably, there are two purge air nozzles, with a spacing of ≥880 mm.

[0014] Preferably, both side edges of the extension section are arranged as inwardly inclined beveled edges.

[0015] Preferably, the lower anti-winding plate is provided with a plurality of bolt holes.

[0016] The utility model provides a roll gap blowing device. When a rolling mill produces thick materials above 2.0, the roll gap blowing device of the utility model is used to blow the edge of the strip, which can effectively reduce the oil on the edge of the strip and effectively reduce the cleaning cost of subsequent processes.

[0019] In order to better understand the above technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Combination Figure 2 As shown, a roller gap blowing device provided by the utility model comprises a lower anti-winding plate 1.

[0021] An extended section 11 is additionally provided at the lower portion of the lower anti-winding plate 1 .

[0022] A toothed section 12 is additionally provided at the middle position of the bottom side of the extended section 11 , and the rest of the bottom side of the extended section 11 is a straight section 13 .

[0023] A purge nozzle 2 is fixedly installed at the intersection of the toothed segment 12 and the straight segment 13 .

[0024] The purge air nozzle 2 is connected to an external air source through a purge pipe 3 .

[0025] A solenoid valve 4 is installed on the purge pipeline 3, and the solenoid valve 4 establishes a communication connection with the production system.

[0026] The purge pipe 3 is fixed on the induction heating bottom plate. During the production process of the rolling mill, the roll gap purge device of the utility model will operate together with the induction heating.

[0027] The distance between two purge air nozzles is ≥880mm.

[0028] Both side edges of the extension section 11 are arranged as inwardly inclined bevel edges 14 .

[0029] The roller gap blowing device of the present invention is fixed on the induction heating device, and the running track of the induction heating device is 2350mm at the maximum and 880mm at the minimum. Therefore, the length of the toothed section 12 on the lower anti-winding plate 1 in the roller gap blowing device of the present invention is ≥880mm, and the remaining parts must be cancelled, otherwise they will block the blowing nozzle 2 and cause interference.

[0030] A plurality of bolt holes 15 are formed on the lower anti-winding plate 1 , and bolts are arranged in the bolt holes 15 to fix the lower anti-winding plate 1 .

[0031] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention.
