Description

Portable electrolysis sample processing unit (plant)
Technical field
The utility model relates to a kind of device of technical field of electrolysis processing, specifically is a kind of portable electrolysis sample processing unit (plant).
Background technology
Electrolyzed Processing is to utilize the electrochemistry anodic solution takes place in electrolyte metal principle to work the work piece into a kind of special process method of shape.Add man-hour, workpiece connects the positive pole of dc source, and instrument connects negative pole, keep less clearance between the two poles of the earth, electrolyte flows through between the two poles of the earth, and UNICOM the two poles of the earth make it to form the loop, anode reaches the purpose of removing material thereby electrochemical reaction takes place under the driving effect of operating current.Along with the continuous feeding of the relative workpiece of instrument, workpiece metal is constantly by electrolysis, and electrolysate is constantly washed away by electrolyte, reaches unanimity in final two interpolars gap everywhere, and surface of the work forms and the basic similar shapes of tool work face.Electrolyzed Processing has significant advantage for difficult-to-machine material, processing complex-shaped or thin-walled parts.At present, Electrolyzed Processing has obtained extensive use, as the gun tube rifling, and blade, integral wheel, mould, profiled holes and irregular part, processing such as chamfering and deburring.Because Electrolyzed Processing equipment relatively complexity and price is higher, generally need the special-purpose electrode tool of preparation, be used at present the processing of difficult processing and important workpiece more, for some middle-size and small-size workpiece, few, wide in variety and crudy had the miniature workpieces such as test sample that explicitly call for as quantity, present Electrolyzed Processing equipment can't satisfy miniature workpiece processing requests such as sample.
Find, with sample the requirement of comparison strictness is arranged for test in the corrosion stress corrosion test of GBT15970.4-2000 metal and alloy, but do not provide preparation of specification for the sample that is used for the stress corrosion test through retrieval to prior art.At present, the test processing mode of use the test of using in sample, the especially industrial production to adopt with sample is that machine adds+manually polishes.Though this processing method can guarantee the surface quality and the machining accuracy of sample, should have the homogeneity that method and apparatus can't guarantee the surface stress of processing sample now.In practical operation, in order to reduce the influence of processing method to sample, the part sample has adopted relatively advanced method in process, as utilizes electric pyrogenic process technology processing sample etc.Even the employing fine processing method, any electric pyrogenic process processing, still there be the machining stress layer of thickness more than 0.2mm in specimen surface.The existence of specimen surface stressor layers has a direct impact the test result in later stage, adopt the stress corrosion resistance that the sample of machine add mode preparation can't the actual response material, thereby the test result that makes is had a greatly reduced quality to the directive significance of actual production.
The utility model content
The utility model is at existing sample process technology and equipment above shortcomings, a kind of portable electrolysis sample processing unit (plant) is provided, electrochemical Machining Technology is incorporated into middle-size and small-size sample processing, and simplified corresponding apparatus greatly, just the processing work that gets sample is convenient, efficiently, can be used for preparing fast, flexibly miniature workpieces such as high precision measurement sample, because the electrolytic etching process can not form stressor layers on the processing sample surface, this device is specially adapted to the processing to specimen surface stress sensitive sample and workpiece.
The utility model is achieved through the following technical solutions, the utility model comprises: processing power source, gatherer, electrolytic cell, pump, electrolyte supply nozzle and cathode tool, wherein: processing power source is connected with workpiece to be processed and cathode tool respectively, the electrolyte supply nozzle links to each other with pump, pump is arranged in the electrolytic cell, and gatherer is connected with electrolytic cell.
Described processing power source is portable dc source, can utilize electricity powered by conventional energy to produce low-voltage, the DC operation of big electric current.
Described gatherer is that the bottom is the cube container of funnel type structure, and the side of this gatherer is provided with the suspension handle, can conveniently install or hang on to add on the lathe.
Described electrolyte supply nozzle is the flat mouthful of conduit that port is provided with rectifier.
Because Electrolyzed Processing, the cutter that cathode tool adopts in the time of can be by machined directly replaces, and is like this then further improved the ease of use of this processing unit (plant).The electrolyte supply nozzle adopts portable design, in the electrochemical machining process, working nozzle moves along with moving of cathode tool, in process, be a homeostasis process between electrolyte flow and the process velocity, this and common electrochemical machining process are incomplete same.Gatherer can be fixed or portable according to the different choice of processing work and processing method, this method for designing not only can significantly reduce the demand of process to electrolyte, simultaneously make that also processing mode is more flexible, reduced processing cost and maintenance cost.This apparatus structure is simple, and assembling is flexible, and volume is little, and is with low cost, is specially adapted to directly use on various machined lathes.
