The jet is ejected from the nozzle to form a jet impinging on the cathode conductive substrate. The impact velocity of the hard particles should be such that the force of the hard particles impacting the deposited surface is greater than that of the shot peening in the pneumatic shot peening process. force.

When the deposition liquid is ejected from the anode, a high-speed high-pressure liquid flow is obtained due to a reduction in the diameter of the anode outlet. Specifically, the deposition rate of the deposition liquid at the nozzle is 5 to 10 m/s. Due to the conduction of the anode, the deposition liquid is electrolyzed, and the metal cations in the deposition liquid are electronically reduced to metal atoms on the cathode conductive substrate, and the desired part shape is deposited. At the same time, the hard particles have a large momentum due to their relatively large mass, and a large impulse is generated when impacting the cathode conductive substrate.

The high-speed moving hard particles continue to impact the deposited layer to remove the internal stress during the deposition process, and compressing the deposited layer increases the deposition strength. The hard particles flow along with the liquid flow and continue to rub the surface, which not only helps to remove the buildup and bulge, but also improve the surface. The unevenness of the height is also conducive to the discharge and precipitation of gases, increasing the density and smoothness of the material, and the periodic pulse power supply also contributes to the realization of the shot peening effect, and finally achieves rapid and efficient deposition.

In summary, the present invention is a high-speed jet spray deposition by mixing a deposition liquid stream with hard particles, wherein the hard particles are micron-sized particles having a uniform particle size, and the deposition liquid is used for electrodeposition. Process deposition solution. The jetting of the deposition liquid to the cathode substrate by jetting realizes the rapid manufacturing purpose of jet electrodeposition, and constitutes the jet electrodeposition manufacturing system; the high-speed liquid stream accelerates the hard particles, so that the hard particles can be more impact than the pneumatic shot peening. Force to achieve the purpose of surface strengthening of shot peening.

The liquid circulation system and the hard particle circulation system are provided, and the hydraulic circulation system provides power for the liquid circulation system and the hard particle circulation system, realizes mixing of the hard particles and the deposition liquid, and obtains the jet force.

When the three-dimensional surface shot blasting electrodeposition device of the present invention is in operation, the hydraulic pump 12 extracts the deposition liquid in the liquid storage tank 22 through the stainless steel tube through the filtering device 11, and is throttled by the throttle valve 7 and overflowed by the relief valve 8. After that, after the pressure measurement of the pressure gauge 6, the rubber hose 21 is entered. Due to the high-speed flow of the deposition liquid, a negative pressure is generated at the nozzle of the reservoir 5, and the hard particles are sucked into the rubber hose pipe by the high pressure, and the switch of the valve 4 is passed through the switch. The flow and the stop of the mixed deposition liquid in the pipeline can be realized; when the deposition liquid flows through the titanium alloy insoluble anode 23, it is ejected from the nozzle through the electrolysis of the power source 1, and the metal crystal is reduced on the cathode conductive base 2 body. The deposition layer 26 is obtained; the deposition liquid not involved in the deposition is collected into the deposition tank 15, filtered by the filter 14, and returned to the liquid storage tank 22 by the circulation pump 13 to be recycled again. The hard particles after impacting the deposited layer are collected and collected by the collecting funnel 16 through the support frame 17, and returned to the accumulator 5 through the recovery device 19 to be reused, and the whole process can be continuously processed to realize high-speed and high-efficiency processing.

Preferably, the three-dimensional surface blasting jet electrodeposition manufacturing device is further provided with a stirrer and a heater in the liquid storage tank; the heater is provided with a temperature sensor, and the mixing liquid and the temperature are adjusted. . The power supply adopts an adjustable pulse power source with a frequency range of 0.5 to 2 MHz, a peak voltage of 2 to 15 V, and a pulse width of 30 to 500 ns. The hydraulic pump is a variable pump, the working pressure is more than 10 bar, and the rated flow is not less than 10 L/min. The anode has a diameter of 3 to 5 mm.

According to the actual processing requirements, adjust the output voltage, pulse width, waveform and pulse frequency of the pulse power supply; adjust the throttle valve to control the output flow of the hydraulic pump; adjust the opening size of the reservoir valve to control the content of hard particles in the sediment solution After the output flow is stabilized, the distance between the manipulator and the cathode conductive substrate is controlled by the numerical control device to achieve an optimal deposition effect.

The deposition liquid is ejected at a high speed through a nozzle on the insoluble anode of the titanium alloy, and an electron reduction reaction is obtained on the cathode conductive substrate to obtain a metal nano layer. Since the current density in the central region of the jet is large, a highly localized deposition effect can be obtained, and the desired three-dimensional shape can be obtained by cumulatively depositing the deposited layer in the deposition zone.

For metal surfaces that have been corroded or oxidized, the metal conductive layer can be removed by rust removal under the impact of high-speed hard particles, and deposition is continued on the surface of the metal to strengthen the bonding strength with the substrate, and at the same time due to the hard particles. The impact of the impact strengthens the mechanical properties of the substrate, and achieves shot peening at the same time as the impurity coating, simplifying the process and improving the working efficiency.

In the five-axis linkage manipulator, multiple nozzles can be installed at the same time to realize composite deposition and alternate deposition. The composite deposition solution can also be configured to realize polycrystalline phase deposition and improve the performance of the substrate.

The anode can adopt a front mixed structure or a rear mixed structure; the two structures are basically the same in function, but the two structures have advantages in different occasions.

Specifically, the anode of the front hybrid structure is directly connected to the titanium alloy insoluble anode 23 and the rubber hose 21 as shown in FIG. 2, and the titanium alloy insoluble anode is surrounded by a protective tempered glass cover 24, and the structure is relatively Simple, suitable for hard particles with a relatively large specific gravity. Since the hard particles are mixed with the deposition liquid earlier, the mixing of the two particles is relatively uniform, which is more conducive to the ejection of the fluid at the anode nozzle. However, the equipment with the front hybrid structure is generally cumbersome and suitable for large equipment that does not frequently change the work site.

The anode of the post-mixing structure is shown in Fig. 3. The titanium alloy insoluble anode 23 is provided with a branching pipe 25, which is made of the same material, is screwed and sealed, and has a protective tempered glass outside the titanium alloy insoluble anode 23. The cover 24 is surrounded. Since the hard particles are mixed with the deposition liquid phase at the anode of the tool, the suction mode of the hard particles is generally suctioned by a negative pressure, and the tool anode is easily worn by the titanium alloy insoluble anode 23 due to the sudden inhalation of the hard particles. Therefore, when the anode of the post-mixing structure is used, it is suitable for the case where the specific gravity of the hard particles is relatively light, and the post-mixing device is also relatively light, and is suitable for frequently changing mobile devices in the workplace.

The specific process of achieving shot peening electrodeposition is as follows:

(1) Prepare a deposition solution required for electrodeposition. The main salt crystal is selected and dissolved in distilled water until saturation is reached, and an appropriate amount of additives, buffers, activators and complexing agents are added to improve the processing effect and conductivity of the deposited layer.

(2) Grinding, degreasing, pickling and water washing cleaning of the surface of the cathode conductive substrate 2, and accurately positioning and clamping the cathode conductive substrate with a clamp; the hard particles may be 500-800 μm in diameter, but no matter which particle is selected It is necessary to ensure that the particles are similar in size and are acid washed to remove impurities and to be baked before use.

(3) controlling the height and angle of the numerical control robot 18 by the numerical control device 20, so that the distance between the nozzle of the titanium alloy insoluble anode and the deposited layer is maintained between 2 and 3 mm;

(4) before the deposition, turn on the agitator 10, so that the deposition liquid is fully mixed, turn on the heater 9, so that the temperature is constant at 40 ~ 50 ° C;

(5) Starting the hydraulic pump 12, adjusting the throttle valve 7 and the relief valve 8, the working pressure of the hydraulic pump is more than 10 bar, the rated flow rate is greater than 10 L/min, and the nozzle of the titanium alloy insoluble anode 23 and the diameter of the branching pipe are 3 to 5 mm. Ensure that the hard particles have sufficient velocity to impact the deposition area.

(6) Turn on the power supply 1 and each valve to start the blasting jet deposition manufacturing, adjust the opening size of the valve 4 during deposition, so that the ejection speed of the deposition liquid at the nozzle reaches 5-10 m/s, and control the height of the numerical control robot 18 and the deposition layer in real time. The angle, the moving speed, and the three-dimensional space forming process; when performing surface coating and coating strengthening treatment, the scanning speed of the nozzle is 0.5 to 1 m/s.

(7) The circulation pump 13 is turned on to recycle the deposition liquid; the recovery device 19 is turned on to reuse the hard particles to achieve a solid-liquid circulation, and the processing is continued.

Since the deposition liquid should ensure sufficient pressure and speed of the deposition liquid, the stainless steel pipe of the front stage pressurized portion and the rubber hose of the rear conveying portion are 15 to 25 mm in diameter, and the inner walls of the two are ensured to be smooth.
