[0003] The manufacturing of precision ultra-thin strips usually adopts the rolling process, but the surface of the prepared ultra-thin strips has residual stress. At the same time, the working rolls are in a high-speed, high-temperature and high-load operation environment for a long time, which inevitably causes damage and fatigue on the working roll surface, affecting the forming quality and output of precision ultra-thin strips. Therefore, the existing ultra-thin strip processing technology cannot solve the problems of residual stress on the surface of precision ultra-thin strips and easy damage to the working roll surface. At the same time, in electrolytic processing, thin strip raw materials are difficult to fix on the equipment, and due to the scouring of the electrolyte during the processing, the thin strip raw materials are prone to deformation, and the processing accuracy is low.

[0048] like Figure 1-Figure 4 As shown, an embodiment of the present invention provides a thin strip electrolytic processing equipment, hereinafter referred to as processing equipment, which includes: an upper clamp 12, a lower clamp 13, a pressing member 2, a conveying mechanism 3, a power supply 9, a thickness gauge 4 and a controller 5.

[0049] The upper clamp 12 and the lower clamp 13 are arranged in sequence from top to bottom, the upper clamp 12 is provided with a through groove 121 and an electrolyte channel 122 which are connected from top to bottom, the electrolyte channel 122 is arranged around the through groove 121, and the lower clamp 13 is provided with a groove 131 which is connected in a direction perpendicular to the through groove 121 on one side close to the upper clamp 12, a processing area is formed between the groove 131 and the lower surface of the upper clamp 12, the processing area is connected with the electrolyte channel 122 and the through groove 121, and the processing area is used to accommodate the thin strip material 11; the pressing part 2 is embedded in the through groove 121, and the pressing part 2 is close to the processing area. One side of the zone is used for processing the surface of the thin strip material 11 after power is turned on; the conveying mechanism 3 is used to convey the thin strip material 11 from the input side to the output side of the processing zone, and the conveying direction of the conveying mechanism 3 is perpendicular to the through direction of the through groove 121; the negative pole of the power supply 9 is connected to the pressing part 2, and the positive pole of the power supply 9 is used to connect with the thin strip material 11; the thickness gauge 4 is located on the input side of the processing zone, and the thickness gauge 4 is used to detect the thickness of the thin strip material 11; the controller 5 is connected to the thickness gauge 4 and the conveying mechanism 3, and the controller 5 is used to control the start and stop of the conveying mechanism 3 according to the thickness information detected by the thickness gauge 4.

[0050] When implementing it, Figure 1As shown, during operation, the pressing member 2 is connected to the negative electrode of the power supply 9, and the thin strip material 11 is connected to the positive electrode of the power supply 9. The thickness gauge 4 detects the thickness of the thin strip material 11 input into the processing area. In the working area, the conveying mechanism 3 continuously conveys the thin strip material 11 through the electrolyte channel 122, so that the space between the pressing member 2 and the thin strip material 11 is filled with static electrolyte. Through the electrochemical reaction, the surface of the thin strip material 11 is thinned. After the processing, the thin strip material 11 is driven by the conveying mechanism 3 and conveyed to the input side of the processing area again. The thickness gauge 4 detects the thickness of the thin strip material 11. The operator can adjust the position of the pressing member 2 in the through groove 121 according to the thickness measured by the thickness gauge 4. After the adjustment is completed, the above operation is repeated to remove the surface of the thin strip material 11 for the second time until the processed thin strip material 11 is thinned. After the strip material 11 reaches the target thickness, the thin strip electrolytic processing equipment is turned off to complete the processing of the thin strip material 11. In the present application, the pressure-coated part 2 and the thin strip material 11 are non-contact processed, which avoids the residual stress on the surface of the thin strip material 11 during the rolling process. Compared with the traditional electrolytic processing method of placing the thin strip material 11 in a flowing electrolyte for flushing, in the present application, the pressure-coated part 2 and the thin strip material 11 are non-contact processed, and the electrolyte in the electrolyte channel 122 is in a static state during processing, and the position of the pressure-coated part 2 in the through groove 121 is continuously adjusted by the controller 5 until the thickness of the thin strip material 11 meets the manufacturing requirements, thereby reducing the risk of deformation of the thin strip material 11 when flushed by the flowing electrolyte, ensuring the manufacturing quality of the thin strip material 11, and improving the yield rate.

[0051] It should be understood that during the movement of the thin strip material 11 in the processing area, a small amount of electrolyte will flow out along the gap between the processing area and the thin strip material 11. The outflowing electrolyte can be collected outside the processing area, or the input and output sides of the processing area can be sealed with paraffin before the thin strip material 11 enters the processing area each time. No specific limitation is made here, as long as the outflow of electrolyte from the processing area can be slowed down.

[0052] like Figure 1 As shown, specifically, in this embodiment, the thin strip electrolytic processing equipment also includes: a first driving component, the driving end of the first driving component is connected to the side of the pressing component 2 away from the processing area, and the first driving component is controlled and connected to the controller 5, and the first driving component is used to drive the pressing component 2 to move in the vertical direction.

[0053] During operation, each time the processing of the thin strip material 11 is completed, the conveying mechanism 3 conveys the thin strip material 11 to the thickness gauge 4 for measurement, and transmits the measured thickness information to the controller 5. The controller 5 controls the movement of the first driving component by analyzing the thickness information, and drives the pressing part 2 to move in the vertical direction in the through groove 121, so as to change the processing gap between the side of the pressing part 2 close to the processing area and the bottom surface of the groove 131. Compared with the traditional operator controlling the processing position of the pressing part 2 in the through groove 121, the method of using the controller 5 to control the driving of the first driving component can ensure that the removal amount of the surface of the thin strip material 11 after each cycle is equal, thereby improving the processing accuracy of the processing equipment.

[0054] like Figure 2 and Figure 4 As shown, specifically, in this embodiment, the processing equipment also includes a high-speed camera 6 and an optically highly transparent glass 7. The optically highly transparent glass 7 is embedded in the upper clamp 12. The high-speed camera 6 can observe the surface of the thin strip material 11 in the processing area through the optically highly transparent glass 7. The high-speed camera 6 is used to collect the distribution information of the electrolysis products on the thin strip material 11, and the high-speed camera 6 is connected to the controller 5. The controller 5 is also used to control the moving distance of the pressing part 2 in the vertical direction according to the distribution information of the electrolysis products.

[0055] During operation, the high-speed camera 6 is placed on the output side of the processing area. When the conveying mechanism 3 transports the thin strip material 11 in the processing area, the high-speed camera 6 monitors and analyzes the distribution information of the electrolytic products on the surface of the thin strip material 11 in real time through the optically highly transparent glass 7. During this process, a certain distance, i.e., the processing gap, must be maintained between the pressing part 2 and the thin strip material 11. After the thin strip material 11 is processed once, the distance between the pressing part 2 and the thin strip material 11 will become larger due to the thinning of the thin strip. At this time, the thickness gauge 4 detects the thickness of the thin strip material 11 after processing. If the thickness of the thin strip material 11 does not meet the requirement, the controller 5 controls to close the conveying mechanism 3, and at the same time, the first driving component starts to drive the pressing part 2 to move in the through groove 121 along the vertical direction until the processing gap between the side of the pressing part 2 close to the processing area and the bottom surface of the groove 131 meets the processing requirements (that is, the thickness information is fed back to the controller 5, and the controller 5 controls the movement of the first driving component to adjust the position of the pressing part 2 inside the upper clamp 12 according to the thickness information to maintain the original processing gap and complete the adjustment of the processing gap), and the electrolyte is refilled in the electrolyte channel 122, that is, the new electrolyte is replaced and the liquid inlet and outlet are closed. After the liquid outlet, the conveying mechanism 3 is started again to input the thin strip material 11 into the processing area, and the above operations are repeated to complete multiple processing on the surface of the thin strip material 11 until the thickness of the thin strip material 11 reaches the target thickness. When the thin strip material 11 is electrolytically processed in the processing area, the controller 5 can control the first driving component to start in real time according to the distribution information of the electrolytic products on the surface of the thin strip material 11 detected by the high-speed camera 6, and the first driving component drives the pressing member 2 to move a corresponding distance in the vertical direction, that is, the gap between the side of the pressing member 2 close to the processing area and the bottom surface of the groove 131 can change according to the different distribution of the electrolytic products at different positions on the thin strip material 11, so that the processing gaps at different positions are different, and further keep the removal amount of different areas of the thin strip material 11 equal, thereby improving the processing accuracy of the processing equipment.

[0056] Specifically, in this embodiment, the material of the lower clamp 13 is a ferromagnetic alloy. The material of the lower clamp 13 can be an aluminum nickel cobalt magnet or other ferromagnetic alloy, which is not specifically limited here. Since the ferromagnetic alloy has excellent magnetic properties and a small temperature coefficient, when the thin strip material 11 enters the processing area, it is adsorbed in the groove 131 of the lower clamp 13 made of the ferromagnetic alloy, avoiding deformation of the thin strip material 11 due to insufficient rigidity during clamping, which affects the processing accuracy.

[0057] Specifically, in this embodiment, the material of the upper clamp 12 is a polymer. The upper clamp 12 can be high temperature resistant plastic, rubber or other polymers, which are not specifically limited here. Since the polymer has corrosion resistance and insulation properties, the upper clamp 12 and the pressure-covering part 2, the thin strip material 11 and the lower clamp 13 can prevent the conduction of current and heat during the electrolytic processing, and resist the erosion and corrosion of various chemical substances, thereby extending the service life of the processing equipment, and avoiding the shape error caused by the insufficient rigidity of the thin strip material 11 itself during the clamping process, thereby ensuring the processing accuracy of the formed workpiece.

[0058] like Figure 4 As shown, specifically, in this embodiment, the contour shape of the pressing member 2 includes T-shape, rectangle or U-shape. Of course, the pressing member 2 can also be other contour shapes, which are not specifically limited here, as long as the pressing member 2 has a processing plane that can contact the processing area. Among them, the width b of the processing plane of the pressing member 2 is ≤10 mm, and the length a of the processing plane is greater than the width c of the thin strip material 11. Such a setting ensures that the current density is evenly distributed during the processing.

[0059] Specifically, in this embodiment, the conveying mechanism 3 includes: a plurality of pulleys 31, a conveyor belt 32 and a second driving component, wherein the plurality of pulleys 31 are arranged at intervals; the conveyor belt 32 is wrapped around the plurality of pulleys 31 to form a closed loop, and the conveyor belt 32 is used to circulate the thin strip material 11; the driving end of the second driving component is connected to the pulley 31, and the second driving component is connected to the controller 5 for control, and the controller 5 is also used to control the second driving component to drive the pulley 31 to rotate, and the pulley 31 drives the conveyor belt 32 to rotate. Among them, the pulley 31 can be provided with 2, 3, 5, etc., which is not specifically limited here, as long as the conveyor belt 32 is wrapped around each pulley 31 to form a closed loop.

[0060] During operation, the second driving component only needs to drive one of the pulleys 31 to rotate, and the friction between the conveyor belt 32 and the pulley 31 can drive the transmission belt to move. During this process, the thin strip material 11 placed on the conveyor belt 32 is transported into the processing area at a uniform speed for electrolytic processing, that is, the conveyor belt 32 and the thin strip material 11 pass through the processing area together, which is convenient for operation.

[0061] like Figure 1As shown, in some embodiments, the processing equipment also includes a machine tool spindle 81, a data collector 51 and a displacement control card 52, the lower fixture 13 is arranged on the machine tool 8, the pressing part 2 can move with the machine tool spindle 81 to feed to the tool setting position and then remain stationary (that is, the movement of the pressing part 2 in the vertical direction can be driven by the machine tool spindle 81, at this time, the machine tool spindle 81 (that is, the first driving component), the lower fixture 13 is fixedly connected to the machine tool 8, the data collector 51, the controller 5, and the displacement control card 52 are connected in sequence, the displacement control card 52 is used to receive the output data of the controller 5 and feed it back to the machine tool spindle 81, so that the machine tool spindle 81 can drive the pressing part 2 to move in the vertical direction; the data collector 51 collects the collection data of the thickness gauge 4 and the high-speed camera 6 and transmits the data to the controller 5, the controller 5 respectively controls the first driving component, the second driving component, and the displacement control card 52, completes the control of the distance between the pressing part 2 and the thin strip material 11 and the transmission mechanism 3, and facilitates the installation operation.

[0062] At the same time, the present invention also provides a thin strip electrolytic processing method, using the thin strip electrolytic processing equipment as described above, the method comprises the following steps:

[0063] S100, moving the upper clamp 12 and the pressing member 2 to the initial position and then keeping them still;

[0066] S400, start the conveying mechanism 3, send the thin strip material 11 into the processing area, drive the thin strip material 11 to pass through the processing area at a constant speed, the power supply 9 connects the thin strip material 11 and the pressing part 2 in the processing area with the electrolyte as the medium, and the electrolyte and the thin strip material 11 undergo an electrochemical reaction to complete the surface removal and thinning of the thin strip material 11;

[0067] S500, after the thin strip material 11 completes one cycle driven by the conveying mechanism 3, the power supply 9 and the conveying mechanism 3 are turned off, the thickness of the thin strip material 11 is measured by the thickness gauge 4, and the thin strip material 11 enters the input side of the processing area again, and the gap between the side of the pressing part 2 close to the processing area and the bottom of the groove 131 along the vertical direction is adjusted according to the thickness measured by the thickness gauge;

[0068] S600, repeating steps S400 to S500, measuring the thickness of the thin strip material 11 by the thickness gauge 4, until the thickness of the thin strip material 11 after being moved out of the processing area reaches the target thickness, and then closing the thin strip electrolytic processing equipment.

[0069] After completing multiple electrolytic processing of a thin strip material 11 in the processing area through the above method and meeting the thickness requirements (i.e., the removal amount of the thin strip material 11 in different areas is equal to achieve the target thickness), the power supply 9, the controller 5, the conveying mechanism 3 and other components are turned off, which is convenient to operate and improves the processing accuracy.

[0070] Specifically, in this embodiment, the electrolyte includes sodium nitrate solution or sodium chloride solution; and / or the concentration of the electrolyte is 5%~50%; and / or the inlet pressure of the electrolyte is 0.00 MPa~2.00 MPa; and / or the temperature of the electrolyte is 0℃~50℃.

Exemplarily, the processing voltage of the power supply 9 can be 0 V, 20 V, 35 V, 40 V, etc., and the processing voltage of the power supply 9 is not specifically limited here, as long as the processing voltage between the pressure-coated part 2 and the thin strip material 11 is guaranteed to be within the range of 0 V to 40 V.
