Description

Technical Field

[0001] The invention relates to a standing wave water-cooled online quenching device, belonging to the technical field of aluminum profile production equipment. Background Art

[0002] As aluminum profiles are widely used in industries such as industry and transportation, the requirements for the quality and mechanical properties of aluminum profiles are getting higher and higher. In the prior art, the strengthening mechanism of aluminum profiles is mainly online quenching, and its specific production process is: extrusion-quenching-cutting-straightening-sawing-framing-aging. The effect of quenching directly affects the mechanical properties of the profile, and the rate of temperature drop of the profile in the quenching section is proportional to the performance of the profile. The current quenching methods are generally fan cooling and water cooling. Fan cooling is a process in which the fan at the profile outlet provides airflow to cool the high-temperature profile; while water cooling is a process in which the profile passes through a water trough for cooling when it is discharged.

[0003] The current water-through cooling quenching device is to set plug plates at both ends of the water tank, and the plug plates at both ends of the water tank are respectively provided with a feed port and a discharge port. The aluminum profile enters the water tank from the feed port for quenching and cooling and then comes out from the discharge port. The water level in the water tank is low, the water circulation volume is small, and the cooling effect is poor; in addition, the cooling water directly sprayed on the high-temperature profile is likely to cause the profile to deform, affecting the final quenching quality. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a standing wave water-cooled online quenching device for the above-mentioned prior art, which eliminates the plug plate, increases the water level in the water tank, increases the total amount of cooling water and the water circulation volume in the water tank, and effectively ensures the final cooling effect.

[0005] The technical solution adopted by the present invention to solve the above-mentioned problem is: a standing wave water-cooled online quenching device, which includes a water tank, a bracket is arranged in the water tank, a conveying roller is arranged on the top of the bracket, and standing wave nozzles are arranged on the front and rear sides of the conveying roller. The front and rear standing wave nozzles are arranged opposite to each other, and the nozzle of the standing wave nozzle is facing inward and obliquely upward.

[0009] Optionally, the water guide plate includes a horizontal connecting plate, the horizontal connecting plate is connected to the bottom of the bracket, and the first water retaining folding plates are arranged on the front and rear sides of the horizontal connecting plate and are inclined downward.

[0010] Optionally, the water supply nozzle includes two nozzle side plates that are symmetrically arranged front and back, and the front and rear two first water retaining folding plates are respectively arranged parallel to the front and rear two nozzle side plates.

[0011] Optionally, the water supply nozzle includes two nozzle side plates arranged symmetrically front and back, and the water guide plate includes a vertical connecting plate, which is connected between the front and rear nozzle side plates, and the vertical connecting plate is arranged perpendicular to the nozzle side plates, and two left and right second water retaining folding plates are arranged on the top of the vertical connecting plate.

[0012] Optionally, a first water supply pipe is connected to the bottom of the standing wave nozzle, and a second water supply pipe is connected to the bottom of the water tank.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] 1. The present invention eliminates the plug plate and arranges a standing wave nozzle near the feed port and the discharge port of the water tank. The standing wave nozzle can replenish water to the water tank on the one hand, and can form a water seal effect on the other hand, which prevents water from overflowing from the water tank to a certain extent, increases the water level in the water tank, increases the total amount of cooling water and the water circulation amount in the water tank, and effectively ensures the final cooling effect;

[0017] 2. The present invention arranges a water guide plate above the middle water supply port, which can effectively prevent the cooling water from being directly sprayed onto the profile and causing the profile to deform. At the same time, the water guide plate is conducive to the circulation of cooling water in the water tank, effectively ensuring the final quenching quality;

[0018] 3. The conveying roller in the water tank of the present invention can be tilted to adjust the height of the profile in the water tank, which can meet the quenching requirements of profiles of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS
