Description of the Invention: [Technical Field of the Invention] The present invention relates to a surface treatment method for a metal guard, and particularly relates to a blackening of a metal tool surface by a wrench and a tool. To obtain a surface treatment method for black and silver two-color workpieces. [Prior Art] Conventional metal workpiece surface treatment methods _ numerous, there are blackening treatment on the surface of the metal workpiece, so that the metal workpiece has a black and silver two-color appearance, which can give the metal workpiece a better product texture, widely accepted by the producer Welcome with consumers. However, the surface of the workpiece made by such a surface treatment method often occurs after a period of use, causing rust marks on the surface of the workpiece, seriously damaging the texture of the product, and even being rejected by consumers. In addition to the above surface treatment method, another TW555626 patent provides a further surface treatment method, which is to first electroplate the workpiece 'to make a plating film on the surface of the workpiece' and then remove the partial film and blacken it, and also obtain black, Silver two-color workpieces, while using the plating film to enhance the anti-rust effect. However, this kind of surface treatment method requires various surface treatment steps such as electroplating, film removal and blackening, which makes the surface treatment method more complicated and greatly increases the production cost. In addition, it is worth mentioning that 'TW541354 patent case and 200821410 The patent application 'is related to the conditions and materials for the blackening, blackening or oil film treatment of the present invention. 201235510 [Summary of the Invention] The main purpose of this test is to provide a surface treatment method which can be used to treat metal workpieces into a two-color surface, which has anti-rust effect and low production cost. In order to achieve the above object, the present invention provides a polishing two-color workpiece surface treatment method comprising the following steps: color development, rust prevention, oil film treatment, partial polishing, and electrocoating. The color development step is to take a metal workpiece into a strong chemical, so that the workpiece is blackened by chemical reaction. The anti-aged step is to take the immersion oil after the hair color treatment, so that the rust preventive oil covers the surface of the workpiece and fills the capillary hole of the workpiece. The oil film treatment step is to take the rust-preventing workpiece and remove the rust-preventing oil on the surface of the workpiece. The partial polishing step is to take the oil film-treated workpiece, and remove the partial surface (four) material of the workpiece so that the partial surface of the workpiece is the starting color of the workpiece. In the public - the electric money step is to make a partial electric painting after the partial throwing. The change is based on the fact that the light-based two-color yarn transfer method does not require additional Wei or the formation of electroplating surface, which can have good abilities and low cost and high product thief characteristics, and has great market potential. [Embodiment] 201235510 Hereinafter, only the embodiment of the invention can be described as an embodiment, but it is not intended to limit the scale of the bribe. Referring to FIG. 1 and FIG. 2, the present invention provides a method for treating a surface of a polished two-color workpiece, which is used for surface treatment of the workpiece i. The workpiece 1 can be various wrenches, sleeves or the like, and H reads other The surface treatment of red crafts is also indispensable. The polishing two-color surface treatment method of the invention can make the surface of the workpiece i appear silver and black, wherein the silver material is made of the metal material itself, and the black color is formed by reacting the metal material with the chemical agent. In the case of color, in the case of selecting a metal material and a chemical agent, such as an oxidizing agent of copper and copper, the surface treated by the surface of the present invention may also have red and black or other colors other than silver and black. The method of polishing the surface of the two-color workpiece of the present invention comprises the steps of coloring, rust prevention, oil film treatment, and local electric field painting. Preferably, a sandblasting step is additionally included before the coloring step. The sand blasting step is a small-scale sand _ splashing on the surface of the metal workpiece 1 to the bribe, so that the sand hits the surface of the turn, and the surface of the surface to be atomized and rough touched, the step of the sand is the lake It is _ small-sized beads, such as steel balls, glass beads, etc., so that the surface of the transfer is subjected to high-speed dense impact of the beads. Increasing the surface of the workpiece __ force, anti-weakness of the red parts, anti-stress rot The nature of the machine. On the other hand, after the _ fine treatment, the surface of the workpiece is also atomized, and the texture of the product can be improved. The color development is to immerse the metal workpiece i in a strong chemical agent, so that the blackening of the surface chemical reagent reacts with the process of the process. The blackening generally means that the surface is blackened, and the selected particles are selected. Select the appropriate chemical for the workpiece material. The anti-mine is to immerse the workpiece i after the chromogenic treatment into the anti-iron oil, so that the _ oil covers the surface of the workpiece and fills the workpiece with the fineness of the workpiece, and if the workpiece is made by casting, it will have a lot of impurities. Capillary pores. The oil film treatment is to treat the surface oil film of the workpiece 1 after the rust-proof treatment. 'Removal: n-surface oil of the surface, specifically, the immersion aid can be immersed in the chemical agent' and the JL piece table _ 嶋 oil In addition, only the correction, the series of pores still have anti-mineral oil, so that I will not lose _ _, preferably, in the oil film treatment can make (4) chemical slightly heated, so that the chemical fine temperature is higher than the room /m, so that the workpiece can be naturally dried immediately after the oil film treatment step. The partial polishing is to partially polish the workpiece i after the oil film treatment to remove the material of the partial surface of the workpiece, so that the material inside the reading is exposed, that is, the partial surface of the workpiece will be revealed as the original color of the workpiece material. Other parts of the table _ simply for the hair color black office to produce ugly color, preferably, the local polishing step to use a grinding machine, polishing machine or milling machine X machine, physical processing to remove the material on the surface of the workpiece. The electrocoating described above electrically coats the workpiece 1 after the partial polishing treatment to impart rust preventive protection to the entire workpiece. By using the above steps, the surface treatment method of the present invention can be used for surface treatment of a wrench, a sleeve or other guards, and the surface of the processed workpiece is partially silver (color of the workpiece material) and partial black (blackening of the workpiece). The color of the 201235510 color), with a good product texture 'further' can be used to blast sand to atomize some or all of the surface, further improving the texture of the product, which is well received by the market. Secondly, the steps of the surface treatment method of the present invention are simplified, and electroplating is not required, so that the cost of the overall surface treatment method is low, which helps to control the production cost, and also has a good anti-rust effect, is not easy to appear rust and inferior products, and is greatly affected by Producers or manufacturers are welcome. In summary, the 'this hair _ light double color barrier surface treatment method can use a simple step to produce a product with high texture, which helps the producer to control the production cost, which is actually a function of Wei Bu, and meets the patent requirements of this transfer. , 爰 提 提 提 提 提 爰 爰 爰 爰 爰 爰 爰 爰 爰 爰 爰 爰 爰 爰 。 。 BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a flow chart of the present invention.
