Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen laser welding machines, in particular to a high-purity nitrogen laser welding machine. Background Art

[0002] In modern industrial production, laser welding is widely used in various metal processing fields as an efficient and precise welding technology. Laser welding uses a high-energy-density laser beam as a heat source and achieves rapid melting and fusion of metal workpieces by precisely controlling the movement of the laser beam, thereby achieving the purpose of welding. However, in the traditional laser welding process, a protective gas, such as nitrogen, is usually required to prevent oxidation and contamination of the welding area and ensure welding quality.

[0003] Existing laser welding machines have some shortcomings in gas protection. First, the purity of the nitrogen used often cannot meet the requirements of high-quality welding, which leads to defects such as oxidation and porosity during the welding process. Secondly, the nitrogen supply system may have problems such as low efficiency and high cost. In addition, the existing welding equipment may not be compact enough in structural design, the operation is complicated, and the stability and reliability of the equipment are difficult to guarantee after long-term work.

[0020] The utility model has the following beneficial effects:

[0021] 1. In the utility model, the nitrogen making component is composed of four tanks, one of which is used for caching the external compressed air, and the other two are carbon molecular sieve devices. The carbon molecular sieve has different adsorption capacities and adsorption speeds for oxygen and nitrogen, and the pressure swing adsorption principle is used to separate nitrogen from the air. In the nitrogen making machine, the carbon molecular sieve can adsorb oxygen and nitrogen in the air at the same time, but the carbon molecular sieve has a larger adsorption capacity for oxygen than nitrogen. Therefore, when the pressure increases, the carbon molecular sieve adsorbs more oxygen molecules than nitrogen molecules. When the pressure decreases, the oxygen molecules adsorbed by the carbon molecular sieve will be desorbed first, while the nitrogen molecules remain in the carbon molecular sieve. By controlling the change in pressure, the separation of oxygen and nitrogen can be achieved, thereby obtaining high-purity nitrogen. The remaining tank is used for nitrogen storage and gas protection during laser welding.

[0022] 2. In the utility model, the nitrogen in the air is separated by adopting the principle of pressure swing adsorption, and the adsorption capacity and speed difference of carbon molecular sieve for oxygen and nitrogen are utilized to realize the preparation of high-purity nitrogen. This design not only improves the purity of gas protection during welding and ensures the welding quality, but also reduces energy consumption and operating costs. Through the fixed connection method of the body, key components such as the gas pressure gauge, control system, circuit system, chiller, laser and nitrogen generator are tightly integrated to achieve compact structure and simple operation. In addition, the setting of the water temperature observation window enables the operator to monitor the working status of the chiller in real time to ensure that the laser operates at the optimal temperature, further improving the stability and reliability of the equipment.

The nitrogen generator component consists of four tanks, one of which is used for caching external compressed air, and the other two are carbon molecular sieve devices, which utilize the adsorption capacity of carbon molecular sieve for oxygen and nitrogen. Due to the difference in the amount and adsorption speed, the principle of pressure swing adsorption is used to separate nitrogen from the air. In the nitrogen generator, the carbon molecular sieve can adsorb oxygen and nitrogen in the air at the same time, but the adsorption capacity of the carbon molecular sieve for oxygen is larger than that for nitrogen. Therefore, when the pressure increases, the carbon molecular sieve adsorbs more oxygen molecules than nitrogen molecules. When the pressure decreases, the oxygen molecules adsorbed by the carbon molecular sieve will be desorbed first, while the nitrogen molecules remain inside the carbon molecular sieve. By controlling the change in pressure, the separation of oxygen and nitrogen can be achieved, thereby obtaining high-purity nitrogen. The remaining tank is used for nitrogen storage and gas protection during laser welding.
