JPS61157700A - Apparatus for supplying electric current to sample to be electropolished - Google Patents

Abstract

PURPOSE:To improve remarkable work efficiency by bringing metallic samples into close contact with conductors by means of an upper conductor in an apparatus for simultaneously electropolishing many metallic samples and by supplying electric current to the samples through the conductors. CONSTITUTION:Metallic samples 4 are piled up in a box-shaped sample setting plate 1 and brought into contact with lower, right and left conductors 5. The upper conductor 6 of a clamp 3 is brought into contact with the upper samples 4, and clamp screws 2 are driven to set all the samples 4. The resulting sample set is suspended from an electrically conductive hanger 7 and put in an electrolytic soln. 8 from the top of an electrolytic cell. When electric current is supplied between the sample set as the anode and an electrode in the cell as the cathode, electricity passes through the samples 4 through the conductors 5, so all the samples 4 are uniformly electro-polished.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a sample energization device for an apparatus for simultaneously electrolytically polishing a large number of metal samples.

[Prior art] Conventionally, when electrolytically polishing one side of a large number of metal samples at the same time, especially when electrolytically polishing samples that are to be used for experimental investigation, one side of the sample is coated with an insulating paint, and one side is coated on the outer periphery. 1 piece
The lead wires were tied together and energized.

[Problems to be solved by the invention] However, in this case, it takes time to apply and dry the paint, and it also takes time to tie up the lead wires, making it inefficient for quality confirmation tests at production sites and causing problems with product quality. There were many obstacles in terms of delivery times.

In order to automate this polishing and save labor, it is necessary to energize a large amount of lead wires at once without bundling them.

The purpose of the present invention is to solve the above-mentioned drawbacks of the prior art.
Our purpose is to provide a non-binding device.

[Means for Solving the Problems] The gist of the present invention is to provide an apparatus for electrolytically polishing a large number of metal samples at the same time, in which stainless steel conductors are attached as electrodes in four directions, top and bottom, left and right, of a box-shaped sample set plate. An electrolytic polishing method characterized in that the upper conductor is movable up and down, and after setting a large number of metal samples, the upper conductor is brought into close contact with each conductor, and the conductor makes it possible to conduct electricity through the group of metal samples. Sample energizing device. Applicable metallic materials of the present invention are copper and copper alloys.

[Function] A large number of metal samples are stacked on a box-shaped sample set plate, brought into contact with the top, bottom, left and right conductors, and tightened, thereby making the entire sample an anode. By applying electricity, the surfaces of a large number of metal samples, which are @ poles, are gradually dissolved and all of them are uniformly polished.

[Example] An example of the present invention will be described with reference to FIG. Samples 4 are stacked on a box-shaped sample set plate 1 from the bottom and brought into contact with the bottom and left and right conductors 5. Sample 4 after stacking next
is in contact with the upper conductor 6 of the clamp 3, and the clamp screw 2
Tighten the sample to complete the sample set. Next, the sample set is suspended from the energizing hanger 7, inserted into the electrolytic solution (phosphoric acid) 8 from the top of the electrolytic bath, and the water sample cellar 1~ is used as the anode, and the electrode of the electrolytic bath is used as the cathode. Electricity flows through the box, and all of the samples set are polished uniformly.At this time, the bottom of the box used is narrower and more slanted than the top, and many holes are drilled in the bottom plate of the box. As shown in Figure 1, when using a cellar 1, the box-shaped sample set is placed in an electrolytic bath in a stable state.
~ can be done.

[Effects of the Invention] As described above, the present invention eliminates the need for conventional lead wire bundling and insulating coating, and enables automation of multiple polishing operations at the same time, significantly improving work efficiency and saving labor.
