A method for manufacturing a cookware accessory without artificial polishing according to an embodiment of the present invention will be described with reference to fig. 7. In the production process, the polishing aims to remove flaws on the surface of the metal fitting, so that the texture of the product is expressed, and the product is more attractive and elegant.

Polishing is mainly aimed at the following aspects: 1. defects in the material itself, such as: scratches, wire drawing, bruising, etc.; 2. defects caused during production and transportation, such as: burrs and flashes caused by blanking, wire drawing and wrinkling caused by forming, and gouges caused by poor protection in the circulation process; 3. the surface process can not meet the quality requirement, such as: the surface is not smooth enough, and the process requirement is mirror polishing or sanding; 4. oxidation of the metal surface by welding, etc.

In addition, because most of formed metal accessories are small parts, such as handles, auxiliary lugs, cover handles, handles and the like, the variety is various, the shapes are different, and the standardized production is difficult, the automatic polishing is carried out by using automatic equipment, the production cost can be greatly improved, so that in the actual processing, the polishing process is basically finished manually, the dust generated by polishing can harm the health of workers, meanwhile, the efficiency of manual polishing is low, the polishing quality is difficult to control, and a plurality of factors seriously restrict the development of the industry.

In view of the above, the inventor creatively optimizes and innovates the existing production process and flow by analyzing the polishing purpose, the quality requirement of the finished product and each link of the production flow and combining the manufacturing and processing experience of many years, and provides a novel preparation method without manual polishing, which comprises the following steps:

s1, preparing materials: according to the processing requirements, purchasing an accessory blank meeting the surface brightness process requirement, and performing film coating protection on the accessory blank.

S2, blanking: and (4) feeding the accessory blank into a high-precision die for processing and forming to obtain an accessory rough blank.

S3, bending and forming: and bending the fitting rough blank to form a fitting body.

S4, assembling: the accessory body and the sheath 6 are buckled to obtain a finished product;

s5, cleaning: cleaning and deoiling the finished product;

s6, quality inspection; performing quality inspection on the finished product processed in the step S5;

s7, packaging: and packaging the finished product qualified by quality inspection.

The method mainly starts from three aspects of material preparation, blanking and bending forming to realize the manual polishing-free method:

in step S1, the polishing process is optionally performed before preparation, that is, the polished plate is purchased according to the requirement of the finished product process. Specifically, when the material is prepared according to the size, specification and thickness of the plate required by the accessory, the polishing process is preposed in the material preparation link, and a processing factory for professional mechanical polishing performs plane machine polishing on the surface of the plate through automatic equipment according to the requirement of the surface process of the finished product, so that the defects of the material book are removed, and the process requirement of the finished product is met, such as: mirror polishing or sanding. The high-quality polishing is carried out at the plate stage because the automatic polishing is easy to realize at the plate stage, the polishing efficiency is high, the polishing quality is easy to control, and the cost is low.

In addition, the polished plate needs to be protected by coating to reduce the defects such as bruising and scratching during production, transportation and circulation.

In step S2, a high-precision mold is selected and used during blanking, and the thickness of the material is reduced while the strength of the product is ensured by industrial design, so as to manage and control burrs and fins generated during blanking, and reduce or weaken the influence of the burrs and fins on the quality.

In step S3, the rough blank of the fitting is bent, so that the strength of the product can be improved, and burrs generated in the blanking process can be covered or hidden after bending, for example: the burr of handle seat is rolled over to the product direction, forms invisible face, and the burr part of connecting portion 2 is folded after bending earlier, hides in the below of handle, can not see at ordinary times, also can not influence and hold the sense, and the burr part of handle body is wrapped up by sheath 6 when the assembly, forms invisible face, because these surfaces are invisible, consequently need not polish.

In conclusion, the method has the advantages that the polishing process is preposed, the materials are protected by coating, the precision of the die is improved, the thickness of the product is reduced, the structure of the product is optimized, the assembling mode of the accessory main body and the sheath is changed, and the like, so that the manual-free polishing in the preparation process can be realized, the restriction of the technology and the health of polishing workers on the accessory industry is avoided, the polishing workers can be separated from the dirty and messy working environment, and the automatic production is facilitated.

While embodiments of the invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
