Description

Assembly for welding reinforcing piece and upright column reinforcing plate on upright column through hinge installation

Technical Field

The utility model relates to an automobile parts technical field, concretely relates to hinge mount reinforcement and stand reinforcing plate welding assembly on stand.

Background

The development trend of light weight, safety and low energy consumption of automobiles promotes the development of high-strength steel plates, the trend of necessity is to adopt advanced ultrahigh-strength steel to replace the traditional low-strength steel plates, and the adoption of the high-strength steel plates can also obviously improve the collision safety of automobiles. However, as the strength of the steel plate is improved, the difficulty of processing parts is also increasing. For the stamping forming process, thinning and high strength are dual factors for deteriorating formability, so that a vehicle body part is easy to crack in the forming process, and excessive resilience is easy to generate to influence subsequent assembly of a vehicle body. The heat treatment mode is one way to realize the high strength of the final part, and the hot stamping forming technology is a mode of combining heat treatment and high-temperature forming to realize the high strength of the part, so that the contradiction between the high strength and cold forming can be well solved. However, with the application of hot stamping steel in a large quantity, the requirements on the collision performance of parts after hot stamping of materials, such as cold bending performance and impact toughness, are correspondingly improved, and the requirements cannot be met by the traditional hot stamping steel.

The existing mainstream technology is the aluminum-free coating hot forming steel plate which can be used for improving the anti-collision capacity and the overall safety of a vehicle body and protecting passengers in the vehicle, and meanwhile, the hot forming steel plate can also reduce the mass of the whole vehicle and save oil consumption, so that the hot forming steel plate is widely used in A, B column reinforcing plates, floor parts and front-end modules of the vehicle. However, the welding process of the hot-formed steel plate without the aluminum coating can not avoid the generation of splashing, burrs and welding beads. Currently, visible spatter of a welded thermoformed part is cleaned mainly by shot blasting before welding, control of welding process parameters and polishing after welding. With the large-area use of the aluminum-plating-layer-free hot forming part, a series of problems of unreasonable structural design, improper welding surface matching, incomplete treatment of an oxide layer on the surface of a plate or deformation caused by treatment, incomplete debugging of welding parameters, incomplete polishing after welding and the like occur, and splashing among welding parts is generated. Aiming at the hot forming upright post without the aluminum coating, high frequency friction abnormal sound is generated in the whole road test process due to large splashing, and the abnormal sound cannot be repaired by conventional means after being generated, so that the attention of customers is easily caused, and complaints are generated.

Therefore, there is a need to develop a new welded assembly of hinge-mounted stiffener to pillar stiffener.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a hinge mount reinforcement and stand reinforcing plate welding assembly on stand can solve the technical problem that splashes that welding process produced lead to way examination or driving process high frequency friction abnormal sound.

The utility model discloses a hinge mount reinforcement and stand reinforcing plate welding assembly on stand, including stand reinforcing plate and the hinge mount reinforcement on the stand, the hinge mount reinforcement welding is in on the stand reinforcing plate on the stand to the bottom of hinge mount reinforcement is equipped with a plurality of bottom solder joints on the stand, is equipped with a plurality of facade solder joints on the facade of hinge mount reinforcement on the stand, the face profile degree of hinge mount reinforcement and stand reinforcing plate face of weld on the stand is all less than or equal to 1.0 mm; and sealant is arranged around the welding spots at the bottom.

Furthermore, an avoiding structure is arranged at the position of the vertical surface welding point.

Further, the diameter of the sealant is 30 mm.

The utility model discloses following beneficial effect has been brought:

(1) the surface profile of the welding surface is controlled, so that the welding spatter of the aluminum-free coating thermoformed part can be reduced;

(2) an avoidance structure is designed on the opposite surface welding spot, so that the visible splash at the welding spot can be conveniently cleaned and polished manually after the reinforcement installed on the upright post through the hinge and the upright post reinforcement plate are welded together;

(3) before welding, spot welding sealant is coated at the position of a welding spot at the bottom, and after the coating is finished, the hinge mounting reinforcing piece on the stand column is folded and welded with the stand column reinforcing plate, so that the splashing generated in the invisible welding area at the bottom is controlled.

To sum up, the utility model discloses avoided the car easily to produce the problem of high frequency friction abnormal sound at the way examination or driving process from now on, promoted user's driving physical examination.
