Abstract
The utility model relates to a characters and patterns etching device with an electrolytic scanning function, the device adopts a common use cathode tool with electrolytes jets in an oblong, a needle tube shape or a soft brush shape, for the characters and patterns precise etching of steel moulds or the dermatoglyph decoration of the injection moulds lumen in the scanning operating mode instead of the manual steel mould carving method and manual titration etching method. The device develops a new application field of electrolytic machining technology, the utility model has the advantages of simple structure, easy fabrication, high precision, high work efficiency, less investment and easy realization, and the utility model is an ideal etching device.
Description
The utility model belongs to a kind of improvement of electrochemical Machining Technology.
The current electrolysis process technology is to the mechanical part in addition of some quite complicated metals, no matter the hardness of its material and toughness how, all have good machining precision and work efficiency.This compares with other mechanical processing tools, has unique advantage.But, technically it must by different part requirements design and make than part itself complicated the special cathode of Duoing as machining tool.And carve workpiece for the tiny punching block various, that figure is complicated of those numbers of words, be difficult to design for this reason and make corresponding special cathode instrument, even make the special cathode instrument, but because processing work also only needs one, this considers it also is very non-remunerative from economic angle.This is that electrochemical Machining Technology can't be in the major obstacle that obtains promoting aspect the character pattern engraving of punching block.Therefore, at present domestic general all the main manufacturing process of method as the punching block character pattern such as to chisel, profile tracer and photomechanical production add conventional manual dropper titration corrosion by hand.And the workpiece accuracy that the former processed is poor, rough surface, decorative effect are very undesirable, can't with external like product than beautiful.Many and tiny to some numbers of words, arrange the compact space of a whole page, the engraving of particularly positive body word is then more difficult, and working (machining) efficiency is very low simultaneously.Though the latter can local overcome the former some weak point, but still has etch depth shallow partially (being generally 0.3mm), operate shortcomings such as complicated, the difficult grasp of technological parameter.
Above-mentioned prior art, " mould manufacturing manual (MM) " the 8th chapter the 5th joint published in China Machine Press nineteen eighty-two and Shanghai science tech publishing house published in 1985 " the mould design with make simple and clear handbook the 4th chapter the 4th, 8 of letter and introduction all arranged in saving.
The purpose of this utility model is exactly in order to overcome the deficiency of above-mentioned prior art, the tradition that changes electrochemical Machining Technology feeds the method for operation and special cathode structure, and design a kind of general cathode tool, adopt the scanning method of operation, to a kind of electrolysis scan text pattern etching device of punching block character pattern processing manufacturing.
The utility model mainly is made up of five parts.As shown in Figure 1, comprising the electrolysis scanning general cathode tool of etching (hereinafter to be referred as general negative electrode) (1), lathe (2), electrolyte circulation system (3), direct supply (4) and etched anode workpiece (hereinafter to be referred as workpiece) (5).
Principle of work of the present utility model can be described in detail as follows by Fig. 2 and Fig. 3:
Workpiece (5) through literal design, photomechanical production, after baking is contained in metal fixture (8) in the work nest (7) and is fixed in lathe (2) and is equipped with on the work top of insulating barrier (6), and is connected with the positive pole of direct supply (4).General negative electrode (1) is fixed on lathe (2) and is equipped with on the main shaft of insulation clamper (9), and its conduction weld tabs (22) is connected to the negative pole of direct supply (4), the character pattern coverage of its electrolysis nozzle for liquid (19) alignment pieces (5).Fastening mother sieve (2) is used for fixing conduction weld tabs (22).The liquid feeding end of the liquid pump (10) of electricity fluid circulation (3) inserts in the electrolytic solution (12) of electrolytic bath (13) by woven hose (14), and the outlet end of liquid pump (10) is connected to liquid valve (11) is connected on the electrode body (18) of general negative electrode (1) again by woven hose (14) top.In addition, tensimeter (15) is in order to the pressure of monitoring electrolytic solution, and reometer (16) and voltage table (17) are used for surveying work electric current and voltage.
In energized, start lathe, start after the liquid pump, workpiece (5) is done at the uniform velocity mobile back and forth on same surface level by lathe (2) drive.Electrolytic solution is constantly sent in the electrode body (18) of general negative electrode (1) with certain pressure by woven hose (14), is shaped on the position injection of character pattern continuously to workpiece (5) by electric nozzle for liquid (19).Because the positive pole of direct supply (4) is connected to workpiece (5); its negative pole is connected to the conduction weld tabs (22) of general negative electrode (1); make between general negative electrode and the anode workpiece electric field that forms certain intensity; under this electric field action; a large amount of negative ions enter on the workpiece position of unprotect film in the character pattern rapidly; thereby, carry out anodic solution very soon at these positions, to reach etched purpose.Like this, adopt general cathode tool designed as that make,, have certain depth and well-proportioned etching body just can obtain required character pattern requirement by electrolysis scanning etching.
The utility model compared with the prior art, significant technical progress is arranged, it replaces special cathode with general negative electrode, can carry out etching and processing to the workpiece of different shape, and, can carry out refine and intensification to character pattern again, or injection mold cavity is made dermatoglyph modify as long as make the rectangle electrolytic solution nozzle of general negative electrode into needle tube shape or soft brush shape, owing to adopt scan mode to drive workpiece, so easy to process, precision is high, work efficiency is also high.In addition, the utility model also has simple in structure, small investment and easy characteristics such as realization.It has opened up a new application for electrochemical Machining Technology, is a kind of desirable Etaching device.
