[ detailed description ] embodiments
For a further understanding of the objects, technical effects and technical means of the present invention, reference will now be made in detail to the following description taken in conjunction with the accompanying drawings.
In the following examples, the intermediate coating, the liquid soil-filling agent and the top coating are all common commercial products.
For example, the liquid earth supplement may be an epoxy earth supplement for pacific chemical: the baking temperature of the agent A and the agent B is 150 ℃, and the baking time is 20 minutes; the primer surfacer is prepared by low-temperature primer surfacer of Hansheng paint and low-temperature solvent according to the weight part ratio, the baking temperature is 60 ℃, and the baking time is 30 minutes; the finish paint is prepared from a low-temperature finish paint of Korean paint, a low-temperature curing agent and a low-temperature solvent according to the weight part ratio, and the baking temperature is 60 ℃ and is baked for 30 minutes.
Referring to FIG. 2, a flow chart of steps of a method for processing a metal workpiece with a ridge effect according to the present invention is shown. The invention relates to a metal workpiece processing method with a ridge effect, which comprises the following steps:
step 100: casting a metal workpiece in a mould, wherein the ridge in the mould is discharged independently by using an electrode so as to enhance the effect of the ridge on the mould, and correspondingly, the effect of the ridge after the metal workpiece is cast and molded is more obvious;
step 200: painting the surface of the metal workpiece, namely, eliminating the step of powder coating in the prior art, and directly painting the primer on the metal workpiece, so that the appearance effect that the edge line is covered by the thicker film thickness ratio after the powder coating is avoided;
step 300: adopting a liquid soil-supplementing agent to supplement soil for the metal workpiece encapsulation area so as to cover the welding mark of the metal workpiece surface encapsulation area, and grinding to obtain a metal workpiece with a smooth and uniform surface;
Step 400: after soil is supplemented, painting is carried out on the surface of the metal workpiece in a secondary coating process, so that the smoothness of the surface of the metal workpiece is further improved;
step 500: the surface of the metal workpiece is coated with finish paint, so that the metal workpiece has decoration and protection effects.
Wherein the metal workpiece is a magnesium alloy workpiece or an aluminum alloy workpiece.
The electrode is a copper electrode, the discharge effect of the copper electrode is better, and the copper electrode is manufactured according to the structure of a metal workpiece.
When the residual discharge allowance of one electrode is 2% -4%, the electrode can be replaced by a new electrode to continue discharging when the residual discharge allowance is 3%, so that the problem that the discharging effect cannot be guaranteed due to abrasion in the discharging process of the electrode is solved, and the edge line effect in the die is obvious.
In the step 500, two layers of middle painting can be continuously coated according to the condition of the metal workpiece to eliminate the defects of holes, lines and the like on the surface of the metal workpiece and obtain the metal workpiece with a smooth surface.
Wherein, the steps 200 to 500 all include a baking step, and the baking temperature and the baking time are adjusted according to actual conditions.
