Description
Technical field
The utility model belongs to subway body construction accessory technical field, especially relates to a kind of underground automobile side wall
Corrugated plating.
Background technology
Subway is mostly a welding tractor in existing welding technique, and due to the limitation of spot-welding technology, the weld seam of subway is big, work
Skill precision is low, have impact on the overall attractive in appearance and security of subway, easily there is solder skip and situation about snapping.
With the development of science and technology, Laser Welding is mainly used in welding thin-walled material and low speed welding, weldering in the 1970s
Termination process category heat-conduction-type, i.e. laser emission heated partses surface, surface heat are internally spread by heat transfer, pass through control
The parameters such as width, energy, peak power and the repetition rate of laser pulse, melt workpiece, form specific molten bath.Due to it
The advantages of unique, it has been successfully applied in micro-, miniature parts precision weldings.
Online laser welding in railway systems is largely with the assembling and connection of bodywork parts.Main application includes ground
Iron covering for roofs Laser Welding, luggage-boot lid Laser Welding and vehicle frame laser welding.Body structural member include car door, body side wall framework and
The laser welding of column etc. can improve bus body strength, strengthen the safety and reliability of subway.
With advances in technology, the subway that subway especially exports proposes higher requirement to welding, so swashing
It is imperative on subway that flush weld is applied, but due to the high-precision requirement of Laser Welding, common subway case fitting part is
Through being unable to meet demand, it is necessary to redesign and produce the subway case fitting part for meeting new pattern laser welding technique needs.
Utility model content
Technical problem to be solved in the utility model is：A kind of underground automobile for meeting laser welding needs performance is provided
Side wall corrugated plating.
A kind of underground automobile shortwave shape side wall corrugated plating, it is characterized in that：Including corrugated plating, arc-shaped wave, straight flange, arc-shaped side,
Position-limited edge I and position-limited edge II；
Cold rolling is distinguished on the corrugated plating and forms arc-shaped wave, straight flange, arc-shaped side, position-limited edge I and position-limited edge II, and the ripple
The length of card is 128mm, thickness 0.6mm；
The arc length 48mm of the arc-shaped wave, and its arc radius is 982mm；
The length of the straight flange is 40mm, and straight flange is mutually perpendicular to position-limited edge II；
The arc-shaped side arc length is 40mm, arc radius 1000mm；
The position-limited edge I is connected with arc-shaped side, and position-limited edge I is parallel with position-limited edge II；
The outer convex direction that the arc involves arc-shaped side is identical.
The length of the position-limited edge I and position-limited edge II are 10mm.
By above-mentioned design, the utility model can bring following beneficial effect：The utility model both sides are changed into round
Slip over and cross, the probability that the moulding of use and size make to crack during process and use substantially reduces, in external form more
It is attractive in appearance.Unicast model detects two side clearances and≤1mm, trough face model inspection center 20mm scopes internal clearance≤0.1mm, distortion
≤ total length * 0.1%, diagonal difference≤1.5mm, cross section perpendicular degree≤1.5mm, free state gap≤4mm.Make the chi after processing
Very little and error is more accurate, meets the technical requirements of present laser welding.
