Greatly, larger is injured to physics and chemistry staff；（Two）Conventional electrolysis corrodes, and using the principle of anodic oxidation, sample is accommodated with fixture
Metallographic electrolytic etching, but efficiency is too low.
Utility model content
Technical problem to be solved in the utility model is, for the shortcoming of above prior art, proposes that a kind of electrolysis is rotten
Metallographic producing device is lost, highly versatile, simple in construction, efficient, practical, cost is low, pollution-free, easy to operate, can solve gold
Efficiency is low when mutually examining, laboratory pollution problem, improves operating efficiency, safe.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is achieved in the following ways：A kind of electricity
Solution corrosion metallographic producing device, includes the specimen holder of horizontally disposed and conductive energy, in the specimen holder centre position
Negative electrode stand provided with conductive energy, the specimen holder is mutually not in contact with each other with negative electrode stand, the specimen holder and negative electrode platform
Shape is in liquid reservoir between frame, and oxalic acid aqueous solution is provided with the liquid reservoir, is placed in the liquid reservoir by liquid
The sample flooded, is provided with DC current regulator power supply, the DC current regulator power supply positive pole and sample outside the specimen holder
Product frame is connected, and negative pole is connected with negative electrode stand.
So, in metal lographic examination, multiple metallographic specimens can be made simultaneously, in addition, corrosive agent uses oxalic acid aqueous solution,
It is pollution-free during experiment, so that staff's health and safety are effectively protected, the device highly versatile, simple in construction, efficient, practical,
Cost is low, pollution-free, easy to operate, can solve that efficiency during metal lographic examination is low, laboratory pollution problem, improves work effect
Rate, it is safe.
The technical scheme that the utility model is further limited is：
Foregoing electrolytic etching metallographic producing device, specimen holder for square, and size be length × width × height=18cm ×
18cm × 8cm, thickness is 0.2cm.
Foregoing electrolytic etching metallographic producing device, negative electrode stand for square, and size be length × width × height=10cm ×
10cm × 8cm, thickness is 0.2cm.
Foregoing electrolytic etching metallographic producing device, specimen holder, which outwards turns down 90 ° with negative electrode stand bottom and formed, to be strengthened
Plate, sets reinforcing plate to improve intensity, increases service life.
The beneficial effects of the utility model are：In metal lographic examination, multiple metallographic specimens can be made simultaneously, in addition, rotten
Erosion agent uses oxalic acid aqueous solution, pollution-free during experiment, so that staff's health and safety are effectively protected, the device highly versatile,
