Sharing technology take you home reunion moment

2021-01-29
Another year to travel, the train carrying returned to her hometown people from all over the country, sharing the reunion moment.
From green train to high-speed train, with the rapid development of high-speed railway in our country, the more time on my way home to shorter, more and more closer to home.
Car body materials by ordinary alloy steel material to stainless steel, aluminum alloy profiles, change in the material, drive the improved processing technology, cutting, welding, advanced technology has been introduced into the manufacturing line of railway vehicle.
a, cutting
bodywork production process is as follows: first, the purchase of aluminium alloy raw materials according to the size of the materials and water cutting, processing after welding into different parts, these parts are grouped, compound into one body.
the locomotive of the steel structures of about 20% 30% of special-shaped parts, especially the locomotive driver chamber, the auxiliary device of the body parts, such as suitable for selection. Cutting the flexible manufacturing, cutting process is easy to realize the automatic control, can greatly shorten the production cycle and reduce the manufacturing cost, improving product quality. So cutting has replaced the traditional processing way, become the domestic and foreign railway vehicles in manufacturing sheet metal blanking of the main means.
2, welding
from iron car to the high-speed train, train 'appearance level' is higher and higher, has higher requirement for welding processing technology. Because of the traditional resistance welding technology, have a certain convex surface of the solder joint inevitable mark, body sealing and spot welding structure is poor, is not widely used high-speed emu car body products.
welding can be continuous welding and sealing welding, and heat concentration, small welding deformation, the body of the flatness bump less than 1 mm, achieve the goal of surface welding deformation, discoloration, create good appearance, no coating stainless steel car body products, and through the welding technology, vehicles, car body static strength and fatigue strength improved quality to reduce, good sealing, improve product quality and commercial quality, make it possible to adopt stainless steel car body of high-speed emu.
every year Spring Festival, the same is pleased to go home, change is the increasing progress of technology. Technology makes a closer, let reunion don't have to wait.
