Problems solved by technology

The chemical etching solution uses a highly corrosive and volatile acidic liquid to react with the metal. The reaction is violent and releases a large amount of heat. The whole process is difficult to control, it is difficult to control the processing accuracy, and it is difficult to form a smooth and sharp edge.
In addition, strong corrosive and volatile acidic liquids are harmful to personnel who work in this environment for a long time and will cause environmental pollution

Embodiment 1

[0019] The method for manufacturing the scraper provided by the present embodiment, as shown in Fig. 1, Fig. 2 and Fig. 3, comprises the steps:

[0020] a. Cover the electrolytic protective layer on the thin metal plate, and use a printing machine to print the common ink used in traditional printing on the front surface 2 and the rear surface 3 of the metal plate 1 to form an electrolytic protective layer. During the printing process, the metal plate 1 Electrolysis window 4a and electrolysis window 5a (that is, the gap of the protection layer) are correspondingly opened on the front and rear surface protective layers 4 and 5 respectively. , compared with the electrolysis window 4a on the front surface of the scraper, it is widened on the side of the knife root (protruding from the root of the blade) 10;

[0021] b. Put the metal plate in the electrolytic tank, connect the positive pole of the DC power supply to the metal plate (the metal plate is used as the electrolysis anode...

Embodiment 2

[0029] The equipment that manufacture scraper method adopts, as shown in Figure 5, there are two dividing plates 105 in its electrolyzing tank 101 and electrolyzing tank and electrolyte nozzle are divided into three compartments 106, and each dividing plate 105 is arranged to allow The passage 107 through which the workpiece and the roller group pass, in each compartment, the workpiece (the metal plate with the electrolysis window) 102 and the electrolyte can be electrically connected to a corresponding independent DC power supply for its electrolysis respectively, and the power supply voltage can be Adjustment; in each compartment, a group of independent electrolyte nozzles are provided on both sides of the roller, and each group of independent nozzles has its corresponding liquid supply pipeline, and there are switches and flow controls for the electrolyte on the respective pipelines. Valve, all the other are the same with the equipment described in embodiment 1.

Abstract

The invention discloses a method to produce a scraping cutter by electrolytic method and a preparation thereof. The invention solves the disadvantages that the existing production method is toxic, pollutes the environment and the accuracy is not easy to control. A metal plate with surface provided with an anti electrolysis protective layer is electrolyzed by electrolytic method and the electrolyte strength can be controlled by adjusting electrolytic voltage or (and) electrolyte concentration or electrolyte velocity during the whole process, thereby ensuring the working precision is easier to control to obtain sharp cutter edge with smooth surface. Besides, raw materials in the invention applied have no harm to human body and do not pollute the environment.

Description

technical field [0001] The present invention relates to a method and apparatus for producing a plurality of scraping blades on a sheet metal. Background technique [0002] Cut tuber fruits and vegetables into shreds and slices, or scrape hard cheese (cheese) and chocolate into velvet, often using a scraper (planing knife). For example, radish etc. are rubbed and rubbed on the front surface of the metal plate against the direction of the knife edge, and the protruding knife edge on the plate surface cuts the scraped material into shreds and slices, which are discharged from the back surface of the metal plate. [0003] The traditional method of manufacturing scraping blades is to stamp a thin sheet of metal with multiple protruding edges. The knife edge formed by stamping cannot form a sharp knife edge, and there are still metal burrs on the edge of the knife edge. It is difficult for this kind of scraping knife to continuously obtain a well-shaped wire or sheet, and it is e...
