Description

Technical Field

[0001] The utility model relates to a metallographic test corrosion area, in particular to a high-efficiency metallographic corrosion device. Background Art

[0002] The first step of metallographic testing is to prepare metal samples. It usually includes cutting, grinding, polishing and corrosion to ensure that the sample surface is smooth and flawless for subsequent observation. Corrosion is one of the important steps in metallographic testing. Corrosion can reveal the grain structure, defects and organizational characteristics of metal materials. Commonly used corrosive agents include acidic and alkaline solutions, such as acidic nitric acid solution, sodium hydroxide solution, etc. Metallographic testing technology has a wide range of applications in metal material engineering, material science and other fields. It can help people understand the microstructure and properties of metal materials more comprehensively, and provide important references for material design and engineering applications.

[0003] When conducting metallographic etching, the experimenter needs to do it one by one, which takes a huge amount of time. At the same time, because the etching liquid is corrosive, the conventional etching method is to clamp the sample with the left hand and use cotton to dip the etching liquid in the right hand for etching, which can easily cause safety accidents. Therefore, when conducting metallographic etching, how to complete the test efficiently and safely has become a difficult problem that needs to be solved urgently. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide a high-efficiency metallographic etching box to solve the problems of low efficiency and low safety of metallographic testing.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is: a high-efficiency metallographic corrosion box, comprising a frame, a sample fixing plate is arranged on the internal protrusion of the frame, and is slidably connected to the frame, a sample fixing block is arranged on the sample fixing plate, and the two are connected by a small spring, a sample is arranged between the sample fixing blocks, an alcohol spray pipe is arranged on the left side of the frame, and the end of the alcohol spray pipe is arranged as a faucet switch, a warm air pipe is arranged on the right side of the frame, and the end of the warm air pipe is arranged as a button switch, a corrosion liquid fixing plate is arranged on the upper part of the frame, and the two are slidably connected, a through hole is opened on the corrosion liquid fixing plate, which is connected to a flange cup, a multi-head support rod is arranged above the flange cup, and the end of the multi-head support rod is arranged as a cotton fixing ring, a lifting rod is arranged above the multi-head support rod, and the end of the lifting rod is an external thread, which is threadedly connected to the multi-head support rod, and a large spring is sleeved on the lifting rod.

[0006] Furthermore, the frame side wall is provided with two upper and lower protrusions, and a limit baffle is provided at the rear end.

[0007] Furthermore, the multiple faucet switches and button switches are independent of each other.

[0008] Furthermore, the sample fixing plate and the corrosion liquid fixing plate are both provided with pull rings, which can be pushed and pulled flexibly.

[0009] Furthermore, the frame is hollowed out so that the experimenter can observe the corrosion degree of the sample at any time.

[0010] Furthermore, the flange portion of the flange cup can be stably stuck in the through hole of the corrosive liquid fixing plate.

[0011] Furthermore, the front end of the sample fixing block is arranged as a trapezoidal groove, which can stably clamp the sample.

[0012] The beneficial effects of the utility model are as follows: through the multi-head support rod, multiple samples can be corroded at the same time, which greatly improves the corrosion efficiency. At the same time, it avoids the contact between the experimenter and the corrosive liquid and reduces the danger of the metallographic test. Finally, through the alcohol nozzle and the warm air pipe, the sample after the corrosion is completed can be immediately rinsed to avoid excessive corrosion and improve the success rate of the metallographic test.
