Description

Technical Field

[0001] This utility model belongs to the field of copper-based steel strip production technology, and in particular relates to a pulse airflow quenching device for copper-based steel strip. Background Technology

[0002] The definition of a copper-based steel strip pulsed airflow quenching device is a device specifically designed for quenching copper-based steel strips. It achieves rapid and uniform cooling by generating pulsed airflow, thereby altering the microstructure and properties of the steel strip to meet specific application requirements.

[0003] When copper-based steel strips are subjected to pulsed airflow quenching, due to their long length, a conveying device is usually required to transport them. Traditional conveying devices typically use drive rollers to drive the copper-based steel strips. Since the copper-based steel strips need to be sprayed for cooling after quenching, a lot of water stains remain on the copper-based steel strips. As a result, slippage is likely to occur during the conveying process, making the conveying of the copper-based steel strips unstable and affecting the quenching effect. Utility Model Content

[0004] The purpose of this invention is to provide a pulse airflow quenching device for copper-based steel strips. By rotating the handle clockwise, the threaded rod rotates, thereby pushing the connecting frame in front. The cooperation of two transmission wheels clamps and fixes the copper-based steel strip, ensuring that the transmission wheels are in close contact with the copper-based steel strip. This method can prevent the copper-based steel strip from slipping during subsequent conveying, ensuring stability during conveying and improving the quenching effect of the copper-based steel strip. Furthermore, this adjustment method can be used for copper-based steel strips of different thicknesses, meeting various conveying needs. It solves the problem that traditional conveying devices usually use drive rollers to drive the copper-based steel strip, which, after quenching, requires spray cooling, resulting in a lot of water residue on the copper-based steel strip, making it prone to slippage during conveying.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0040] Cooling mechanism 3 includes a water tank 31 fixedly connected inside the conveyor table 1. A baffle 32 is provided on the outside of the water tank 31. The bottom of the baffle 32 is fixedly connected to the top of the conveyor table 1. A water pump 321 is installed on the top of the baffle 32. A conveying pipe 322 is provided in front of the water pump 321. One end of the conveying pipe 322 extends to the bottom of the water tank 31 in connection with the water pump 321.

[0041] Among them, the water pump 321 is used to draw water out of the water tank 31, and the water tank 31 is used to seal the top of the water tank 31.

[0042] The water tank 31 is equipped with two spray pipes 33, and several spray heads 35 are installed at the bottom of the spray pipes 33. A connecting pipe 34 is connected between the two spray pipes 33. One end of the connecting pipe 34 passes through the baffle 32 and is connected to the water pump 321.

[0045] One specific application of this embodiment is:

[0046] In use, the copper-based steel strip is passed through the heating furnace 11, the pulse airflow quenching box 12, and the water tank 31, and the copper-based steel strip is placed between the two drive wheels 231. Then, by turning the throttle 241 clockwise, the threaded rod 24 is driven to rotate. The end of the threaded rod 24 will rotate within the limiting ring 232, thereby pushing the front connecting frame 23. The limiting rod 233 will slide on the fixed frame 21. At this time, the front drive wheel 231 will move closer to the rear drive wheel 231. The cooperation of the two drive wheels 231 will clamp and fix the copper-based steel strip, so that the drive wheel 231 and the copper-based steel strip are in close contact. This method can prevent the copper-based steel strip from slipping during subsequent conveying and ensure the stability of the conveying. Then, the motor 234 is started to drive the front drive wheel 231 to rotate counterclockwise. The drive wheel 231 will then convey the copper-based steel strip to the left.

[0047] When the copper-based steel strip enters the heating furnace 11, the heating furnace 11, which includes heating elements and a temperature control system, heats the copper-based steel strip to the required quenching temperature and maintains a stable temperature. The type of heating furnace 11 can be a resistance furnace, induction furnace, etc., and the appropriate heating method is selected according to the material, size, and production requirements of the steel strip. After heating, the copper-based steel strip is transported to the pulse airflow quenching box 12.

The high-pressure gas source provides compressed air or other inert gases, the gas storage tank is used to store the gas and stabilize the gas pressure, the control valve controls the gas outflow according to the set program, and the nozzles convert the high-pressure gas into a high-speed pulse airflow, which is sprayed onto the surface of the steel strip to perform pulse airflow quenching treatment.

[0048] After the copper-based steel strip is quenched, it is transported to the water tank 31. At this time, the water pump 321 is started to transport the water in the water tank 31 to the connecting pipe 34 through the delivery pipe 322, and then split into two spray pipes 33. The water is then sprayed out from the spray head 35, thereby spraying and cooling the quenched copper-based steel strip again, reducing its temperature to room temperature or close to room temperature, so that it can be processed or processed later. The sprayed water will be guided by the inclined plate 36 and then flow back into the water tank 31. The cooled copper-based steel strip then leaves the water tank 31. At this time, the motor 223 is started to drive the front rotating shaft 224 to rotate. The front rotating shaft 224 will drive the rear rotating shaft 224 to rotate through the belt drive of the rear pulley 226. The cleaning brush 225 on the rotating shaft 224 will clean the water stains on the surface of the copper-based steel strip, thereby reducing the water stains.
