The method comprises: coating a corrosion-resistant insulating material coating on the surface of the metal workpiece; according to the pattern to be formed, removing part of the insulating material coating on the surface of the metal workpiece by using laser engraving to expose part of the surface of the metal workpiece and engraving 10 to 400 micrometer engraved strips on the exposed part of the surface of the metal workpiece; etching the exposed part engraved with the engraved strips; and removing the insulating material on the surface of the workpiece after etching and obtaining the workpiece with engraved patterns.
Description
Technical field
The invention relates to a kind of method at metal works surface marking pattern.
Background technology
The pattern processing method of metal surface mainly contains chemical etching, chemical etching, punching press, spark machined, laser engraving.Yet all there is shortcoming in these methods in practical application.For example; The shortcoming of chemical etching and chemical etching is that pre-treating technology is complicated; Need make rough sketch, make operations such as egative film, exposure and development; And be difficult to obtain neat, clean processing edge, along with the increase of workpiece processing thickness, the machining tolerance increase causes machining accuracy to descend.To be this method exert an influence to the character of material itself shortcoming of punching press.For example; Though punching press can be used to process the parts of different-thickness; But need the pressure extrusion metal of high tonnage could form thinner region, this can make these zones of metal become harder, a kind of so-called work-hardening effect occurs; When metal material was relatively thinner, trace also can appear carrying on the back in the punching press back side.Therefore, this kind method is processed the parts that obtain and is produced different speciality in the zone of different-thickness.The shortcoming of spark machined and laser engraving is can the trace phenomenon also can occur carrying on the back in the heat-affected zone that the edge of work produces suitable width down in the situation (following this situation is abbreviated as " dark mark ") that etch depth increases.
Therefore, people attempt through different processing methods being combined working (machining) efficiency and the precision to improve the case of marking on a map deeply.For example, CN 1652027A discloses a kind of surface of golf club head engraving method, and this method comprises surface of the work is coated with mask layer; Utilize the laser beam irradiation mask layer, have the exposed window (laser does not exert an influence to metal) of predetermined lines with formation; The metal surface of the exposed window of chemical etching is to etch predetermined lines then; Remove mask layer at last.Yet this method is the same with chemical etching, and along with the increase of etch depth, the machining tolerance increase causes machining accuracy to descend.
Summary of the invention
The objective of the invention is for overcome existing exist when carrying out degree of depth marking in the metal surface machining accuracy poor, the defective of back of the body trace appears easily, provide a kind of machining accuracy high and can not produce the method for carrying out degree of depth marking in the metal surface of back of the body trace.
The inventor has carried out careful research to existing method of carrying out degree of depth marking in the metal surface, finds that along with the increase of working depth, machining accuracy descends thereupon in chemical etching; When the inventor finds to utilize laser engraving according to required pattern the insulator coating on metal works surface partly to be got rid of; The exposed part that metal works is surperficial is carved out after the rag with certain depth; Carry out etching again and can improve machining accuracy significantly, also avoided simultaneously owing to the phenomenon of laser engraving at the back of the body trace of dark timestamp existence.
The invention provides a kind of method at metal works surface marking pattern, wherein, this method is included in metal works surface coated erosion resisting insulation thing coating; Afterwards according to the pattern that will form; Utilize laser engraving that the insulator coating on said metal works surface is partly got rid of, metal works surface portion ground is exposed and the exposed part that metal works is surperficial is carved out the rag that the degree of depth is the 10-400 micron; Afterwards the exposed part of carving out rag is carried out etching; Remove the insulant of surface of the work after the etching, obtain having the workpiece of marking pattern.
Method at the surperficial marking pattern of metal works provided by the invention has improved machining accuracy significantly, and has avoided the phenomenon of the back of the body trace of dark timestamp.
