Description
Technical Field
[0001] The invention relates to the technical field of electrochemical etching, in particular to an electrochemical etching experimental device. Background Art
[0002] Electrochemical etching is an anodic reaction. The workpiece is placed in the electrolyte as the anode. When the current is turned on, electrochemical dissolution of the metal will occur on the surface of the workpiece. The lattice around the metal atoms is corroded and further ionized and releases electrons (e), exposing the metal atoms.
[0003] The technologies that apply electrolytic etching include electrolytic machining, electrolytic grinding, electrolytic honing, electrolytic polishing, etc. These technologies all use a cathode that has been pre-processed into the required shape, and the processed material as the anode. Through electrochemical dissolution, the electrolytic corrosion action is concentrated and limited to the required area.
[0004] Electrolytic machining (electrochemical machining): A process method that uses an electrolyte that does not form a passivation film and processes complex shapes only through electrolytic etching. As an alternative to traditional dry machining and discharge machining, it has its own unique application areas. Electrolytic grinding: A process method that combines mechanical grinding and electrolytic etching, which has the advantages of improving machining efficiency, reducing grinding wheel consumption, and reducing grinding heat and grinding resistance. Electrolytic honing and electrolytic polishing: The principle is the same as electrolytic grinding. Both are process methods that combine mechanical honing and mechanical polishing with electrolytic etching, and belong to the field of surface etching technology.
[0005] The current electrochemical etching experimental device needs to clamp the experimental workpiece, and then use the cathode grinder connected to the negative pole of the power supply to electrochemically etch the anode workpiece connected to the positive pole of the power supply. Adjust the current size, electrolyte volume and other data during the experiment to obtain various experimental conclusions. Due to the difference in structure between cylindrical workpieces and rectangular workpieces, different experimental devices are required for different experimental workpieces, and the etching methods are also different. The cylindrical workpiece can be etched as a whole by rotation, while the rectangular workpiece is not easy to rotate, and the electrolyte cannot be fully contacted, resulting in incomplete etching, which also causes the rectangular workpiece to require more electrolyte. This makes the electrochemical etching experimental device, due to its fixed structure, only place workpieces of one shape, either rectangular workpieces or cylindrical workpieces, and cannot meet the experimental needs of placing workpieces of different shapes at the same time.
[0006] Therefore, the present invention provides an electrochemical etching experimental device, which can place both rectangular workpieces and cylindrical workpieces in the experiment, thereby meeting the experimental requirements for workpieces of different shapes. Summary of the invention
[0007] In order to solve the problem in the prior art that electrochemical etching experimental devices cannot place workpieces of different shapes, the present invention provides an electrochemical etching experimental device, which, through the design of the electrolytic chamber, can satisfy the experimental requirements for workpieces of different shapes by placing both rectangular workpieces and cylindrical workpieces.
[0008] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an electrochemical etching experimental device, comprising a power supply, a processing box, an electrolytic chamber fixedly connected inside the processing box, and an electrolyte tank fixedly connected to the bottom of the processing box, two sets of sub-gears and motors are installed on one side of the electrolytic chamber, main gears are installed on the motor output shaft, the two sets of main gears and sub-gears are respectively meshed, an electric telescopic rod is fixedly connected to one side of the inner wall of the electrolytic chamber, one end of the electric telescopic rod is fixedly connected to a piston plate, the piston plate is slidably connected to the inner wall of the electrolytic chamber, two arc grooves are opened on the piston plate, middle electrolytic plates are detachably connected in the arc grooves, and the top wall and inner bottom wall of the electrolytic chamber are respectively fixedly connected to the arc electrolytic plates; and the arc electrolytic plates are respectively arranged opposite to the middle electrolytic plates, the middle electrolytic plates and the arc electrolytic plates are both electrically connected to the negative pole of the power supply, and the experimental workpiece is electrically connected to the positive pole of the power supply.
[0009] The principle of the basic scheme is: when the experimental workpiece is cylindrical, the workpiece is placed from the clamping groove into the electrolytic chamber, the processing box is closed, and the motor is started. The motor drives the gear to rotate, and the gear drives the cylindrical workpiece to rotate. The electrolyte tank transports electrolyte to the middle electrolytic plate and the electrolytic plates on both sides. The middle electrolytic plate and the arc-shaped electrolytic plate are both electrically connected to the negative pole of the power supply, and the experimental workpiece is electrically connected to the positive pole of the power supply, so that the electrolyte etches the experimental workpiece in all directions.
[0010] When the experimental workpiece is rectangular, the middle electrolytic plate is removed, the workpiece is placed in the electrolytic chamber, the processing box is closed, the bottom of the piston plate clamps the rectangular workpiece, and the electric telescopic rod is started to move the rectangular workpiece laterally. At the same time, due to the reciprocating motion of the piston, the electrolyte in the electrolyte tank is repeatedly squeezed and sprayed out due to the action of air pressure, so that the electrolyte etches the experimental workpiece in all directions.
[0011] The beneficial effects of the basic scheme are: 1. The electrochemical etching experimental device in the prior art can only place workpieces of one shape, either rectangular or cylindrical, due to its fixed structure, and cannot meet the experimental requirements of placing workpieces of different shapes at the same time. The present invention realizes electrochemical etching experiments on both cylindrical workpieces and rectangular workpieces by making the middle electrolytic plate in the electrolysis chamber retractable.
[0012] 2. The present invention uses the design of a piston plate in conjunction with an electric telescopic rod to allow the workpiece to move laterally, so that the workpiece can be in more comprehensive contact with the electrolyte, allowing the electrochemical etching to be more fully performed, thereby obtaining a more complete experimental effect and reaching more accurate experimental data and conclusions.
[0013] 3. When conducting experiments on rectangular workpieces, the electrolyte in the electrolyte tank is repeatedly ejected by utilizing the air pressure generated by the movement of the piston, thus making up for the problem that the rectangular workpiece requires more electrolyte.
[0014] Furthermore, the electrolytic chamber is connected to the electrolyte tank via a plurality of main drainage pipes and auxiliary drainage pipes, each of which is provided with a drainage pump and each of which is provided with a control valve.
[0015] The beneficial effects of the basic scheme are: starting the drainage pump can transport the electrolyte to the surface of the experimental workpiece through the drainage main pipe, and the drainage sub-pipe can discharge the electrolyte through the air pressure generated by the repeated movement of the piston. At the same time, a control valve is provided so that the drainage sub-pipe is only started when the rectangular workpiece is subjected to the experiment, which makes up for the problem that the rectangular workpiece requires more electrolyte and avoids the waste of electrolyte.
[0016] Furthermore, the main drainage pipes are all connected to the arc-shaped electrolytic plates.
[0017] The beneficial effect of the basic solution is that the electrolyte can be ejected from the arc-shaped electrolytic plate to better contact the workpiece surface and achieve a better electro-etching effect.
[0018] Furthermore, the electrolytic chamber is connected to the electrolyte box via a plurality of corresponding through holes, and a filter screen is arranged in the through holes.
[0019] The beneficial effect of the basic scheme is that such a design enables the gas in the electrolysis chamber to be pressed into the electrolysis chamber when the piston reciprocates, and the electrolyte in the electrolysis chamber can also flow back to the electrolyte tank from the through hole, and a filter is provided in the through hole to reduce the contamination of the electrolyte tank by etching impurities.
[0020] Furthermore, the electrolysis chamber is rectangular, and the arc-shaped electrolysis plate and the middle electrolysis plate are both semicircular.
[0021] The beneficial effects of the basic scheme are: the electrolysis chamber is rectangular, which is convenient for placing rectangular workpieces, and the arc-shaped electrolysis plate and the middle electrolysis plate are both semicircular, which is convenient for placing cylindrical workpieces.
[0022] Furthermore, a clamping groove corresponding to the cylindrical experimental workpiece is opened in the middle of the gear, and an anti-slip pad is provided in the clamping groove.
[0023] The beneficial effect of the basic scheme is that such a design enables the cylindrical experimental workpiece to be fixed by the clamping groove, so that the rotation of the motor drives the gear to rotate, and the rotation of the gear drives the workpiece to rotate, making the electrochemical etching of the workpiece more comprehensive and obtaining more accurate experimental data and results.
[0024] Furthermore, the upper drainage main pipe is communicated with the lower drainage main pipe.
[0025] The beneficial effect of the basic solution is that while increasing the drainage pipeline and allowing the workpiece to more fully contact the electrolyte, the demand for drainage pumps and material consumption are reduced, thereby reducing the cost of the device.
[0026] Furthermore, a temperature controller is provided in the electrolyte tank.
[0027] The beneficial effect of the basic solution is that the temperature controller monitors the electrolyte in the electrolyte system in real time, and through its automatic heating and cooling functions, the electrolyte is kept at a constant temperature to ensure that the electrochemical etching process can proceed smoothly.
[0028] Furthermore, a clamping block for clamping a rectangular workpiece is rotatably connected to the piston plate.
[0029] The beneficial effect of the basic scheme is that when the rectangular workpiece is placed in the rear electrolytic chamber, the rectangular workpiece presses the clamping block, and the clamping block is clamped while the rectangular workpiece is pressed, so that the rectangular workpiece can move with the extension and retraction of the telescopic rod, and the workpiece and the electrolyte can be in more comprehensive contact, thereby achieving a better electrochemical etching effect.
[0030] Furthermore, the motor signal is connected to a controller, and the controller is signal-connected to the control valve, the temperature controller, the electrolytic rod and the electric telescopic rod.
[0031] The beneficial effect of the basic solution is that it enables the device to be controlled intelligently. BRIEF DESCRIPTION OF THE DRAWINGS
[0032] Figure 1 This is an axonometric diagram of the electrochemical etching experimental device in the present invention.
[0033] Figure 2 Cross-sectional view of the electrochemical etching experimental device.
[0034] Figure 3 Cross-sectional view of the electrolysis chamber and electrolyte tank DETAILED DESCRIPTION
[0035] The following is further described in detail through specific implementation methods:
[0036] The figure marks in the drawings of the specification include: processing box cover 1, electrolytic chamber 2, processing box 3, drainage main pipe 4, electrolyte box 5, arc-shaped electrolytic plate 6, drainage auxiliary pipe 7, middle electrolytic plate 8, temperature controller 9, drainage pump 10, sub-gear 11, motor 12, clamping block 13, piston plate 14, electric telescopic rod 15, through hole 16.
[0037] The embodiment is basically as shown in the attached Figure 1-Figure 2 As shown: an electrochemical etching experimental device, including a power supply, a processing box 3, an electrolytic chamber 2 welded inside the processing box 3, and an electrolyte box 5 welded at the bottom of the processing box 3.
[0038] Two sets of sub gears 11 and a motor 12 are installed on one side of the electrolysis chamber 2, and main gears are installed on the motor output shafts. The two sets of main gears and sub gears 11 are meshed respectively. A clamping groove corresponding to the cylindrical experimental workpiece is opened in the middle of the sub gear 11, and an anti-slip pad is provided on the inner wall of the clamping groove. This design enables the cylindrical experimental workpiece to be fixed by the clamping groove, so that the rotation of the motor 12 drives the sub gear 11 to rotate, and the rotation of the sub gear 11 drives the workpiece to rotate, so that the electrochemical etching of the workpiece is more comprehensive, and more accurate experimental data and effects are obtained.
[0039] An electric telescopic rod 15 is welded to one side of the inner wall of the electrolysis chamber 2, and a piston plate 14 is welded to the output shaft of the electric telescopic rod 15. The piston plate 14 is rotatably connected to the side away from the electric telescopic rod 15 with two groups of clamping blocks 13 for clamping rectangular workpieces. The clamping blocks 13 are all right-angled steel blocks. Suction cups are provided on the opposite sides of the two groups of clamping blocks 13. When the rectangular workpiece is placed in the rear electrolysis chamber 2, the rectangular workpiece presses the clamping blocks 13. When the clamping blocks 13 are pressed, they clamp the rectangular workpiece and adsorb the rectangular workpiece, so that the rectangular workpiece can move with the extension and retraction of the telescopic rod, and the workpiece and the electrolyte can be in more comprehensive contact, thereby achieving a better electrochemical etching effect.
[0040] The piston plate 14 has two arc grooves, in which the middle electrolytic plates 8 are detachably connected, and the top wall and the bottom wall of the electrolytic chamber 2 are respectively welded with arc electrolytic plates 6; and the arc electrolytic plates 6 are respectively arranged opposite to the middle electrolytic plates 8. The middle electrolytic plate 8 and the arc electrolytic plate 6 are both electrically connected to the negative pole of the power supply, the experimental workpiece is electrically connected to the positive pole of the power supply, and the top of the processing box 3 is connected to the processing box cover 1 through a hinge buckle.
[0041] The electrolysis chamber 2 is connected to the electrolyte tank 5 through a plurality of drainage main pipes 4 and drainage sub-pipes 7. A drainage pump 10 is provided in each drainage main pipe 4. The drainage main pipe 4 is connected to the inner space of the arc-shaped electrolysis plate 6 and the middle electrolysis plate 8 through the arc-shaped electrolysis plate 6. A control valve is provided in each drainage sub-pipe 7. Starting the drainage pump 10 can transport the electrolyte to the surface of the experimental workpiece through the drainage main pipe 4. The bottom of the drainage sub-pipe 7 is located in the electrolyte. When the piston moves repeatedly, the gas pressure generated will discharge the electrolyte from the bottom of the drainage sub-pipe 7, so that the drainage sub-pipe 7 continuously discharges when the rectangular workpiece reciprocates, making up for the problem that the rectangular workpiece requires more electrolyte.
[0042] The upper drainage main pipe 4 is connected to the lower drainage main pipe 4, which increases the drainage pipeline and allows the workpiece to more fully contact the electrolyte, while reducing the demand for the drainage pump 10 and the consumption of materials, thereby reducing the cost of the device.
[0043] The electrolytic chamber 2 and the electrolyte tank 5 are both connected by a plurality of corresponding through holes 16, and a filter screen is adhered in the through hole 16. Such a design enables the gas in the electrolytic chamber 2 to be pressed into the electrolytic chamber 2 when the piston reciprocates, and the electrolyte in the electrolytic chamber 2 can also flow back to the electrolyte tank 5 from the through hole 16, and the filter screen is arranged in the through hole 16, which reduces the contamination of the electrolyte tank by etching impurities.
[0044] The electrolysis chamber 2 is rectangular, which is convenient for placing rectangular workpieces, and the arc-shaped electrolysis plate 6 and the middle electrolysis plate 8 are both semicircular, which is convenient for placing cylindrical workpieces. The device can perform electrochemical etching experiments on cylindrical workpieces as well as rectangular workpieces.
[0045] A temperature controller 9 is provided in the electrolyte box 5. The temperature controller 9 monitors the electrolyte in the electrolyte system in real time. Through its automatic heating and cooling functions, the electrolyte is kept at a constant temperature to ensure that the electrochemical etching process can proceed smoothly.
[0046] The motor 12 is signal-connected to a controller, and the controller is signal-connected to the control valve, the temperature controller 9, the electrolytic rod and the electric telescopic rod 15, so that the device can be intelligently controlled and easy to operate.
[0047] At the beginning of the experiment, select the required workpiece, put it into the device and start the experiment.
[0048] When a circular workpiece is selected for experiment, the processing box cover 1 is opened, the circular workpiece is placed between the middle electrolytic plate 8 and the arc-shaped electrolytic plate 6, and part of it is placed in the clamping groove, the processing box cover 1 is closed, the motor 12 is started, the circular workpiece rotates, the power supply is started, the circular workpiece is electrically connected to the positive electrode of the power supply, the middle electrolytic plate 8 and the arc-shaped electrolytic plate 6 are electrically connected to the negative electrode of the power supply, the drainage pump 10 is started, the electrolyte is discharged from the drainage main pipe 4, the surface of the workpiece is flushed, and the workpiece is electrochemically etched. Due to the rotation of the circular workpiece, the circular workpiece and the electrolyte can be fully in contact, so as to achieve better experimental results, and the flushed electrolyte will flow back to the electrolyte tank 5 from the through hole 16, and the filter will filter out the impurities generated during etching, so that the electrolyte can be recycled to reduce the experimental cost. At this time, the electric telescopic rod 15 remains stationary and the control valve remains closed.
[0049] When a rectangular workpiece is selected for the experiment, the processing box cover 1 is opened, the middle electrolytic plate 8 is removed, the rectangular workpiece is placed between the arc-shaped electrolytic plates 6, the processing box cover 1 is closed, and the power supply is started, so that the rectangular workpiece is electrically connected to the positive electrode of the power supply, the middle electrolytic plate 8 and the arc-shaped electrolytic plate 6 are electrically connected to the negative electrode of the power supply, and the drainage pump 10 is started to discharge the electrolyte from the drainage main pipe 4 to flush the surface of the workpiece and electrochemically etch the workpiece. At this time, the control valve is opened, and the electric telescopic rod 15 is started. The electric telescopic rod 15 drives the piston plate 14 to reciprocate, and the bottom of the piston plate 14 The clamping block 13 clamps the rectangular workpiece. Due to the reciprocating motion of the piston plate 14, the workpiece moves laterally. At the same time, the piston plate 14 presses the gas into the electrolyte tank 5 through the through hole 16. Due to the effect of air pressure, the electrolyte is ejected from the drainage auxiliary pipe 7 to flush the rectangular workpiece. Due to the lateral movement of the rectangular workpiece, the rectangular workpiece is in more complete contact with the electrolyte. The air pressure generated by the movement of the rectangular workpiece is used to squeeze out more electrolyte, which makes up for the problem that the rectangular workpiece requires more electrolyte, so that the experimental effect is better and more accurate experimental conclusions are obtained.
[0050] The present invention can adjust the power supply voltage to study the influence of different voltages on electrochemical etching, can also adjust the temperature to study the influence of different temperatures on electrochemical etching, and can also compare the electrolyte consumption in the circular workpiece experiment with the electrolyte consumption in the rectangular workpiece experiment to draw corresponding experimental conclusions.
[0051] The electrochemical etching experimental device in the prior art can only place workpieces of one shape, either rectangular or cylindrical, due to its fixed structure, and cannot meet the experimental requirements of placing workpieces of different shapes at the same time. The present invention realizes that the electrochemical etching experiment can be performed on both cylindrical workpieces and rectangular workpieces by making the middle electrolytic plate 8 in the electrolytic chamber 2 retractable.
