Description
Technical Field
The invention relates to the field of carrying concave of an automobile outer covering piece, in particular to a device and a method for enhancing the carrying concave performance of the automobile outer covering piece.
Background
The anti-dent performance is also concave, which means that the part covered on the outer surface of the car body resists the impressed load and generates indentation on the surface. The outer panel of the economical vehicle, such as a closure outer panel, a side wall outer panel, a roof panel and the like, is prone to the problem of insufficient dent resistance, and is visually represented by large deformation of a pressed part or rebound sound when fingers press the outer surface of a vehicle body, which affects the feeling of a user.
The local dent resistance of the automobile outer panel improves two methods used in the prior art. The first is to stick a reinforcing rubber sheet on the inner side of the outer plate of the weak part with dent resistance, and because the price of the reinforcing rubber sheet is higher, the implementation of the scheme will obviously increase the cost of the vehicle. The second method is to use a reinforcing bracket as shown in fig. 1, the reinforcing bracket is welded on the inner plate, a certain gap is kept between the top of the bracket and the outer plate, the top of the reinforcing bracket is provided with a glue groove, and a certain amount of expansion glue is filled in the glue groove in advance. In the coating process, after the expansion glue expands when heated, the gap between the top of the bracket and the outer plate is made up, and the outer plate is supported, so that the dent resistance of the outer plate is improved. The reinforcing support has no universality, completely different supports are required to be used at different outer plates at different positions of the same vehicle or different positions of the same outer plate, great difficulty is brought to the manufacture and the use of the reinforcing support, the expansion rate of the expansion glue is influenced by various factors such as glue variety, glue consumption, temperature and the like, the expansion degree of the expansion glue cannot be accurately controlled, and the condition that the outer plate is not supported due to insufficient expansion and the deformation of the outer plate top is caused due to excessive expansion often occurs. In addition, the expansion glue can only be filled in a welding process in the manufacturing process, when the vehicle is used for a period of time, the expansion glue cannot be filled again for repair after aging and failure, and the reinforcing effect is failed.
The outer covering stamping part of automobile body includes four doors, two covers, left and right fender, left and right side wall, top cap, all includes planking and inner panel like four doors, cover, luggage-boot lid etc. wherein the inner panel matches fixedly with the planking coincidence, and preceding part is equipped with connecting device, also the part is equipped with the interval between corresponding inner panel and the planking.
