( Industry news] High-speed trains production process reveal each every train than cable atltech P high-speed trains production process reveal each train in all cables we usually sit high iron are basically adopt aluminum alloy frame structure, while the city's subway with aluminum alloy car-body, stainless steel car body, etc. As a result of the aluminum alloy material characteristics, the production of high iron is one of the best materials, but the cutting and welding of aluminum alloy, prompt it to become one of the core technologies for high-speed trains vehicle manufacturing. And in and out of the tunnel, on high-speed under high-speed trains air tightness problem is very serious. In the pursuit of comfortable, air tightness of China's high-speed rail could be set to the car pressure fluctuation is less than Mr Per second. This value is less than the indicators of the aircraft hold, so less people sit high iron tinnitus. Section on the car body, a variety of different cross section of the aluminum alloy profiles, the thinnest place. Mm, the thickest place for mm. Aluminium alloy welding is higher than other welding difficulty, not only has high requirements of the constant temperature and humidity to the welding environment, is also on the type of work of the operator body hurt, this, in the domestic several high-speed emu production enterprises are equipped with constant temperature and humidity environment protection welding production workshop. Of car body production process is as follows: first the purchase of aluminium alloy raw materials according to the size and water cut with laser cutting, processing after welding into different parts, these parts are grouped, eventually compound into one body. In this factory, an hour to finish production of car body. Car body machining long weld all completed by robot, small parts by manual welding, start from now and friction stir welding, laser welding, a new welding process has been applied in. Car body points between the car and take the form of the structure bridge head two car. Car models on the basis of in the middle, is divided into a chassis, side walls, roof, side wall, side wall parts respectively welding, etc. And it starts to make a few part of the basic synchronization. The above these combined welded together, a car body. It is aluminum alloy material, the size, the color and size, have the feeling of postmodernism. The hardest car body manufacturing should be head of car body, is a bridge of car body. It basically is the manual compound, process more complex, the size is more demanding. Car body welding is complete, and even in the process of welding, straightening draw is in constant, can be understood as a fine finishing of the steel giant, using the method of grinding. Polishing almost as important as welding, aiming at eliminating stress, to ensure that the body flatness. Installed in the door, showing a complex structure of this area. The door is the emu a security control point, to guarantee the accuracy of the hundreds of thousands of times. After the workers out of the bogie is ready, please will body lifting up, called alight. Drop process, there is always a stunning. Always scene at this moment, because the body itself is not small; Always have a happy time, because is about to enter. When the car body production, after the completion of coating process. Car body many times before and after the putty, primer and paint spraying is also many times, the last of body whole body white appear. Coating the silver car body can't see, become we are in the train on the platform to see the white body. At that time, car body or no wheels, it was with a hovercraft to the general assembly workshop. Emu each train is about more than wire cable, reliable connection must be accurate and correct. Wire cutting area, with white back to simulate real vehicle, press: offline, then to the wire and cable into a bunch of banding. A headset line in daily life can also be a mess situation often appear, more than wire cable neat, here is only per wiring error rate. 。 Is management into a bunch of a bunch of cable, after being installed in the car. Article 2 meters production line, welding machine, automatic lanes, not light weight frame on the assembly line as a small toy, transmitted, welding, flip, output. Car is warm material, floor, air duct, the window, chairs, decoration parts installation, car under large parts mainly transformer, current transformer, etc. , the roof installation of pantograph and main power lines, high-speed trains here be armed completely. The door is the emu a security control point, to guarantee the accuracy of the hundreds of thousands of times. After the workers out of the bogie is ready, please will body lifting up, called alight. Drop process, there is always a stunning. Always scene at this moment, because the body itself is not small; Always have a happy time, because is about to enter. Test finished, high-speed trains has completely meet online conditions, new emu scheduling command, waiting for the factory's private sidings into operating routes, started his journey.
