Description
Technical Field
The invention relates to the technical field of automobile manufacturing, in particular to a thermoforming laser splice welding integrated door ring structure.
Background
Laser tailor welding technology is a new concept in the design and manufacture of automotive bodies. The laser welding adopts laser energy, and automatically splices and welds a plurality of steel materials with different materials, different thicknesses and different coatings, stainless steel materials, aluminum alloy materials and the like to form an integral plate, a section bar, a sandwich plate and the like so as to meet different requirements of parts on material performance, and the device is light by using the lightest weight, the optimal structure and the optimal performance. At present, laser tailor welded blanks are mainly used in the automotive industry. In laser welding, the materials are butted rather than lap joint, which will bring about the following weld characteristics: (1) Reducing the volume of the weld zone, e.g., the weld width is no more than 0.5-1 mm; (2) without increasing the height of the weld; (3) less impact on press formability; (4) After the zinc plating is added on the welding seam, the cathode protection function of the welding seam can be maintained; and (5) in the welding process, the heat affected zone is small.
After the welding is completed, the static and dynamic strength of the weld area is a very important index, and therefore, the weld area needs to be sampled and subjected to a destructive tensile strength test (cupping test) to check the stretch forming performance of the weld area. Generally, the weld has a higher tensile strength than the base material. The laser splice welding plate process has a plurality of advantages compared with the products of the traditional spot welding lap joint process: the method not only reduces the manufacturing cost, logistics cost, the weight of the whole vehicle, assembly tolerance, oil consumption and rejection rate of the whole vehicle, but also reduces the number of peripheral reinforcing parts, simplifies assembly steps and processes, and simultaneously enhances the collision capability of the vehicle, and improves the stamping forming rate and corrosion resistance. In addition, the use of sealant is avoided, so that the method is beneficial to environmental protection.
At present, after a plurality of sheets with different material marks and different material thicknesses are formed into an annular sheet by laser splice welding, a product is obtained by a thermoforming stamping process. The investment of the welding clamp for the material sheets of the door ring products of the single vehicle type is huge, and the welding clamp for the annular material sheets of the hot forming laser welding integrated door rings of different vehicle types cannot be shared, so that the production cost of a vehicle enterprise is greatly increased.
