Description

A kind of engine hood under supporting tool for pretreatment of car coating

Technical field

The utility model relates to a kind of frock, is specially the engine hood under supporting tool that a kind of car coating pre-treatment is used.

Background technology

As everyone knows, car coating pre-treatment and coating, drying process are three big master operations of coating process, and Coating Pretreatment is basic operation, it is to all having material impact film quality, the service life of filming, the processing of filming etc., and the important function of Coating Pretreatment is: 1, the clean surface is provided: by the cleaning of the surface of the work after the operations such as degreasing, rust cleaning, phosphatization, even, no greasy dirt; 2, can significantly improve film adhesive: on the one hand, it is a solid strong overall structure that phosphating coat is joined metal works, for example, Zinc phosphating, what begin to form is ferric phosphate and black iron oxide, grow into trbasic zinc phosphate thereon again, promptly on workpiece, directly generate phosphating coat, do not have obvious boundary therebetween.On the other hand, phosphating coat has porous, and coating can be penetrated among these holes, and application and phosphating coat interlock produce powerful scissors.Like this, just directly overlay on the micro-rough surface of metal works much strong than filming; 3, can significantly improve the corrosion strength of filming: though phosphating coat is thin, but because it is the nonmetallic non-conductive interlayer of one deck, can make the metal works surface change non-conductor into, suppress the formation of metal works surface micro cell, and then effectively stop the corrosion of filming from excellence conductor.

For the processing operation before the application of car bonnet, prior art is directly the bonnet lid to be contained in to carry out pre-treatment on the car body, and so, bonnet rocks in the pre-treatment process easily owing to be not well fixed.When adopting the operation of this kind processing mode, be easy to generate airbag; Greasy dirt is difficult for clean and causes shrinkage cavity; The existence of these defectives will cause the undesirable of bonnet pre-treatment effect, influences the quality of pre-treatment, directly influences the service life of car body.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of engine hood under supporting tool for pretreatment of car coating that can be used with upper engine hood supporting tool for pretreatment in car painting, can make car in coating process, eliminate airbag and shrinkage cavity, improve the pre-treatment quality on bonnet surface.

The technical solution of the utility model is as follows: design a kind of engine hood under supporting tool for pretreatment of car coating, its main points are: comprise latch hook and support bar, the bending of described support bar bottom is " J " font, connects latch hook at this post upper.

The utility model partly is through in the bumper mesopore with " J " font of support bar bottom, the latch hook of this post upper colludes in the snap close of the upper support frock of car bonnet, thereby realize support to the car bonnet, bonnet and vehicle body are maintained a certain distance, avoid rocking of bonnet in the car coating pre-treatment process.

For the utility model lower support bar is installed in the car bumper bar mesopore reliably, above-mentioned support bar bottom bending segment is an acute angle with the angle of vertical section, on this support bar bottom bending segment, be provided with pin-and-hole, and in this pin-and-hole, be equipped with pin, pin is set can effectively avoids support bar from car bumper bar mesopore, to skid off.

Above-mentioned latch hook is inverted dove-tail, and wherein a cell wall is welded on described post upper, so design, this latch hook can with the upper support frock reliable fit of car bonnet.

For fear of the utility model car such as is scratched at the defective that causes, the bending place of above-mentioned latch hook and support bar is arc transition.

Beneficial effect: the utility model can effectively prevent car arbitrarily the rocking of bonnet in the Coating Pretreatment process, for the car coating pre-treatment provides convenience, for follow-up car coating provides convenience, improve the quality of application and the life-span of car, have be skillfully constructed, simple in structure, implement easily, characteristics such as good reliability.
