Embodiment

[0030] Such as figure 1 , figure 2 , image 3 As shown, a teaching electrochemical polishing device includes a DC electrochemical polishing power supply 7 , a constant temperature water bath 108 , an electrolyte polishing tank 103 , and a hanger 111 for polishing parts.

[0031] An air switch, a thyristor voltage regulator, a transformer, and a control circuit board are installed inside the electrochemical DC power supply, and the external control panel includes a voltage regulator 3, an ammeter 6, a voltmeter 5, a timer 4, and an output power polarity converter 8. Reset button RESET9, output terminal 1, indicator light 2. The electrochemical DC power supply can convert 220V single-phase AC power into electrochemical polishing DC output, and the polishing voltage can be set by rotating the voltage regulator knob. The polishing voltage and polishing current are displayed in real time on the ammeter 6 and voltmeter 5 on the front of the power panel.

Abstract

The invention belongs to the technical field of metal surface treatment, and relates to an electrochemical polishing device for teaching. At present, various electrochemical polishing devices are mostly complex in structure and high in safety protection requirement and need to be operated by professionals. The electrochemical polishing device for teaching overcomes the defects, and comprises a direct-current chemical polishing power supply, a constant-temperature water bath kettle, an electrolyte polishing groove and a polishing part hanging frame. The electrochemical direct-current power supply can be used for converting 220V single-phase alternating current into electrochemical polishing direct current to be output. The output voltage is adjusted according to the area of a polished material. The electrolyte polishing groove is placed in the constant-temperature water bath kettle. The polishing part hanging frame is installed in the short axis direction of the cross section of the polishing groove. The electrochemical polishing device for teaching is used for a thin-sheet-shaped single part with the area smaller than 45 mm * 45 mm, simple in structure, convenient to use, low in manufacturing cost, high in safety and short in polishing time. The surface roughness of a polished part is low.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment and relates to an electrochemical polishing device for teaching. Background technique [0002] With the vigorous development of the "mass entrepreneurship and innovation" activities, in order to stimulate students' innovative potential, all primary and secondary schools across the country are actively organizing students to carry out various scientific production, technological innovation and other activities. In the "double creation" activities, Students urgently need a device that can electrochemically polish the surface of various stainless steel plate parts or innovative two-dimensional cutting stainless steel products they make, reduce the surface roughness of the product, improve the smoothness and smoothness of the product surface, and make the samples produced Better performance, more beautiful appearance. [0003] At present, most of the various electrochemical polishing ...
