Laser cutting of bulletproof helmets, have you seen such high-energy processing "black technology"?
Non-metal bulletproof helmets are protective equipment used to prevent the penetration of projectiles or fragments and effectively protect the human head. It must be worn by police officers and security personnel when performing special tasks to protect the human head from projectiles fired by guns. Or damage from explosive fragments, the laser cutting process of bulletproof helmets plays an increasingly important role in the production of helmets.
Laser cutting of bulletproof helmets, have you seen such high-energy processing "black technology"?
The synthetic materials of bulletproof helmets mainly include aramid, PE, bulletproof steel, glass fiber and other materials. Among them, aramid and PE are new high-tech synthetic fibers developed in the 1960s and 1980s. Compared with traditional bulletproof steel, they have The advantages of light weight and high strength have been widely used in the production of bulletproof helmets. At present, the price of aramid and PE materials is more expensive than that of glass fiber. In addition, limited by the characteristics of the material itself, aramid and PE helmets also have certain requirements for preservation. For example, aramid helmets should avoid prolonged exposure to sunlight and avoid Contact with water, etc., while PE helmets should avoid contact with high-temperature objects, etc.
Traditional residual material removal methods and disadvantages:
The residual material after the one-time pre-pressing of the bulletproof helmet needs to be removed with a manually operated band knife saw; during the removal process, firstly draw the line according to the template, and then manually hold the bulletproof helmet and cut it a little with a band saw, which takes a long time and operation. high risk factor. The hardness and toughness of the bulletproof helmet material are relatively large. When cutting, it cannot be cut at one time according to the scribed trajectory. It needs to be repeated many times, which is time-consuming and labor-intensive, and is prone to unfavorable phenomena such as snagging and tearing, which affects the quality of subsequent products.
Bulletproof helmet laser cutting advantages:
1. Non-contact processing, no "knife" wear during laser cutting of bulletproof helmets, no need for auxiliary consumables such as knife molds, and lower operating costs; 2. High energy, high density, ultra-fine, small heat affected area, no "knife" "Cutting force" acts on the workpiece and will not cause deformation of the workpiece;
3. The laser cutting of bulletproof helmets adopts computer graphics to directly output, what you see is what you get, and the software and control functions are powerful, which can realize various processing techniques such as edge trimming, hole opening, and slope cutting;
4. The laser cutting edge of the bulletproof helmet is smooth and fine, no dust, no burrs, no threading, and no secondary treatment is required;
5. Laser cutting of bulletproof helmets is very flexible and convenient because the laser beam is easy to guide and gather to realize transformation in all directions, and is suitable for the processing of any complex and special-shaped workpieces;
6. The laser cutting of bulletproof helmets adopts fully automatic cutting, the processing process does not require manual intervention, the whole process is fast and good, the cutting is accurate and stable, saving a lot of labor and reducing the production process;
3D five-axis laser cutting machine
Technical advantages:
