Description

Technical Field

[0001] This utility model relates to the field of aluminum plate processing technology, and in particular to an anti-jump rolling device for aluminum plate processing. Background Technology

[0002] Aluminum sheet rolling is a key process in metal plastic processing. An external force is applied to the aluminum sheet billet using a rolling mill, causing it to undergo plastic deformation between rotating rolls. This adjusts dimensions such as thickness, width, and length, and optimizes internal microstructure and mechanical properties. The process includes billet pretreatment, rolling and annealing, straightening, and surface treatment. Rolling is divided into hot rolling and cold rolling; the former refines grains at high temperatures, while the latter improves precision at room temperature. This process can produce a variety of products, from ultra-thin foils to thick plates. By adjusting rolling parameters, properties such as strength and hardness can be controlled. It is characterized by high efficiency and high material utilization, and is widely used in aerospace, automotive, and construction industries.

[0003] A type of anti-jump rolling mill for aluminum plate processing, disclosed in Chinese patent CN220160901U, can resist the reaction force applied to the rollers by the workpiece during extrusion, keeping the central part of the roller axis horizontal and ensuring that the thickness of the rolled workpiece remains consistent in the middle and on both sides, thus guaranteeing the rolling quality. However, compared with the prior art and comparative solutions, this rolling mill still has the following problems in actual use:

[0004] During the rolling process of aluminum plates, if the lubrication of the aluminum plate is insufficient or the lubricant on the aluminum plate is unevenly distributed, the friction coefficient between the roll and the aluminum plate will fluctuate. When the rolling speed is high, the friction between the roll and the aluminum plate will increase sharply, resulting in stick-slip phenomenon. This will cause the roll to vibrate periodically, which can easily lead to roll jump. This will cause the aluminum plate to have wavy or striped deformation, affecting the quality of the produced aluminum plate. Utility Model Content

This invention does not involve any improvement to the structure or usage of the electronic components.

[0037] The work process is as follows:

[0038] S1. In use, the aluminum plate passes from the feeding roller 6 on the support frame 5 between the two auxiliary spraying components 4, and then between the two calendering rollers 308.

[0039] S2. Start the second driving component 305. The second driving component 305 drives the transmission rod 307 to rotate through the third gear 306. The transmission rod 307 drives the calendering roller 308 to rotate. The calendering roller 308 drives the transmission belt 310 through the first transmission wheel 309. The transmission belt 310 drives the transmission roller 312 to rotate through the second transmission wheel 311. The transmission roller 312 drives the sliding seat 401 through the pulley 402. The sliding seat 401 drives the spraying brush 408 and the fourth gear 406 to reciprocate on the first connecting frame 105 and the adjusting frame 2 through the spraying component 405.

[0040] S3. Since the two fourth gears 406 on the two auxiliary spraying components 4 mesh with the first rack 107 and the second rack 202 respectively, during the reciprocating movement of the spraying component 405, the spraying component 405 on the two auxiliary spraying components 4 is driven to rotate, and the spraying component 405 drives the nozzle 407 and the spraying brush 408 to rotate.

[0041] S4. Simultaneously, lubricant enters the spraying part 405 from the connecting pipe 404, and then sprays out from the nozzle 407. The spraying brush 408 then evenly coats the lubricant onto the aluminum plate. This prevents fluctuations in the coefficient of friction between the rolling roll 308 and the aluminum plate due to insufficient lubrication or uneven distribution of lubricant on the aluminum plate. It also prevents a sudden increase in friction between the rolling roll 308 and the aluminum plate at high rolling speeds, which could lead to stick-slip and periodic vibration of the rolling roll 308. This helps to avoid roll jump and ensure the quality of the rolled aluminum plate.

[0042] S5. When it is necessary to adjust the rolling thickness, the first drive component 207 is activated. The first drive component 207 drives the first gear 205 to rotate through the second gear 206. The first gear 205 drives the adjusting screw 203 to rotate, thereby driving the adjusting frame 2 to move. The adjusting frame 2 drives one of the calendering rollers 308 and one of the auxiliary spraying components 4 to move, adjusting the distance between the two calendering rollers 308 and the two auxiliary spraying components 4, thereby adjusting the rolling thickness of the aluminum plate.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
