A2-pinch roll: transport and positioning strip head into the double-cut shear. The next roll of the pinch roll using hydraulic gear motor rotation. A3-starting loop device: installation prior to the welder body for the formation of the looper. Looper arm under the action of the hydraulic cylinder to hold up the strip, formed when the looper down. A4-MCD on the device: the inlet and outlet of the welder body has a four-point device. Mobile device right in on the parts by hydraulic motor through a rack and pinion rotation. Typical laser welding process. Welder working process by the following sequence diagram: volume strip with a tail to be adopted by the welder, mobile shears, Block hydraulic cylinder driven into the working position, as shown in Figure 3-1.  As shown, the stiffener welding lead box deformation. Due to error of the bending process, does not guarantee "a few" font both sides of the ribs completely parallel to the side panel, welding stress release will lead to the deformation of the stainless steel side panels, thus affecting the accuracy of box stitching. Shenzhen City Star David Art Laser Technology Co., Ltd. specialized in producing laser marking machine.The parameters of the laser beam, the performance and accuracy of the machine and CNC systems have a direct impact on the efficiency and quality of laser cutting. Especially for the cutting of high precision or the thickness of the larger parts, we must grasp and address the following key technologies: the focus position control technology: One of the advantages of laser cutting beam of high energy density, general> 100W/cm2. As the energy density is proportional to the 4/πd2.
Thyristor medium frequency power supply. Operating frequency than the frequency transformer high two orders of magnitude (typically 10 kHz or less), frequency inverter power transformer volume was significantly reduced. The SCR has the advantage of allowing a larger current, it can be used to power high power inverter. Made of this technology, power and RC Power ballast resistors only the former one 1/8-1/15, size, weight is reduced to 1/3-1/4 of the cost of less than a / 3. PWM-type DC-DC high-frequency switching power supply. DC DC-DC high-frequency switching power supply as the CO2 gas laser excitation source, not only small size, light weight, high efficiency, adaptability, and continuous and pulse modulation output laser power to achieve serialization and standardization. It is used by the customer to avoid the direct exposure to laser pointer .The brightness of the blue  laser pointer  is the lowest.The synthetic power amplification circuit is the power amplification step combination of the components in accordance with the number 2 through the transmission line transformer, and finally a larger power output.
