Description

Technical Field

[0001] The utility model relates to the field of cutting of urea tank brackets, in particular to a laser cutting machine for producing urea tank brackets. Background Art

[0002] Urea tanks are usually used to store urea solution, which is used as a reducing agent in the SCR system on diesel vehicles. The SCR system uses urea solution to convert nitrogen oxides in exhaust gas into harmless nitrogen and water vapor, thereby reducing exhaust emissions from diesel vehicles. The heavy-duty commercial vehicle urea tank bracket is welded with steel pipes and plates. The laser cutting machine uses the energy released when the laser beam is irradiated onto the surface of the workpiece to melt and evaporate the workpiece to achieve the purpose of cutting and engraving. It has the characteristics of high precision, fast cutting, and is not limited to cutting pattern restrictions. The use of laser cutting technology to produce the plates required for urea tank brackets has become a market trend.

[0003] According to Chinese patent number CN214921528U, a laser cutting machine for producing urea tank brackets includes a support device, a collecting device, a flipping device, a longitudinal adjustment device, a lateral adjustment device and a cutting device. The support device includes a support plate and a pressure block. The lower surfaces of the four pressure blocks are connected to the upper surface of the support plate. The collecting device includes a mounting plate, a blanking chute, a box door and a handle. One side surface of the mounting plate is connected to one side surface of the blanking chute, and the upper surface of the mounting plate is connected to the lower surface of the support plate. Although the above patent scheme can collect metal scraps in the cutting process, laser cutting is completed by melting or vaporizing the material under the irradiation of the laser. During the melting or vaporization process, the cutting position will oxidize to form high-temperature powder, which can easily enter the air and affect the processing environment. For this reason, we propose a laser cutting machine for producing urea tank brackets to solve the above problems. Utility Model Content
