Description

Technical Field

[0001] The present invention relates to the field of anode plate processing equipment, and more specifically, it relates to a punching device for anode plate processing. Background Art

[0002] The anode plate is the core conductive component in the electrolysis process. As the anode of the electrolytic cell, it realizes the functions of metal dissolution or protection through electrochemical reactions. Its material needs to have both electrical conductivity, corrosion resistance, and mechanical stability.

[0003] The processing flow of the anode plate usually includes: material proportioning and melting, forming process, cold pressing and stamping, welding and assembly, surface treatment, coating process, hard anodizing, and quality inspection, etc. During the cold pressing and stamping process, the anode plate is usually punched to improve the fluidity of the solution, reduce energy consumption, and improve the electrolysis efficiency. However, the existing anode plate punching devices are only used to complete the punching operation. After punching, one or more perforations will be formed on the anode plate substrate. When the anode plate substrate is sprayed with precious metals or corrosion-resistant coatings (such as iridium and ruthenium oxides) through the coating process, the coating will only be sprayed on the surface of the anode plate substrate and will not be sprayed on the inner wall of the perforation. Therefore, the perforation cannot be effectively protected and is easily eroded by the electrolyte.

[0010] Further preferably, an air jetting channel is arranged in the punch. The air jetting channel is used for connecting with an external air supply system. An air outlet hole is arranged on the air jetting channel. The air outlet hole is located on one side of the lower punch and above the receiving groove.

After the protective coating is cured, a dense protective layer can be formed, isolating the direct contact between the corrosive medium and the substrate, and significantly extending the service life of the anode plate in a strong corrosion environment, thus solving the problem that the perforation formed after punching is easily eroded by the electrolyte.

Detailed implementation manner

[0018] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0019] Embodiment: A punching device for processing anode plates, as Figures 1 - 3 shown, the punching device includes a punch 6, a cylinder 5, a base 1, support legs 3 and a mounting bracket 4. The support legs 3 are fixed to the bottom of the base 1 to lift and support the base 1. The base 1 is rectangular, and there are four support legs 3, which are respectively fixed at the four corners of the bottom of the base 1. The base 1 is used to place the anode plate substrate 2, the mounting bracket 4 is fixed on the base 1, and the cylinder 5 is installed on the mounting bracket 4 and is used to drive the punch 6 to move up and down to perform punching operations.

[0020] In the above technical solution, by controlling the start and stop of the cylinder 5, the up and down movement of the punch 6 can be controlled, so that the anode plate substrate 2 on the base 1 can be punched, so that one or more perforations for electrolyte circulation are formed on the anode plate substrate 2. However, after punching, the anode plate substrate 2 exposes a new metal layer during the processing, and when it comes into contact with the electrolyte or corrosive medium (such as chlorine, acidic / alkaline solution), it will cause chemical or electrochemical corrosion; in addition, punching will change the physical structure of the anode plate substrate 2, and may generate microcracks or burrs, reducing the mechanical strength. Therefore, the punching device in the present invention further includes a mounting seat 7, a drive mechanism 8 and a nozzle 17. The punch 6 is fixed to the cylinder 5 through the mounting seat 7, and the nozzle 17 is located on one side of the punch 6 and is used to spray a protective coating on the inner wall of the perforation formed after punching the anode plate substrate 2.

[0021] Preferably, after the anode plate substrate 2 is placed on the base 1, the anode plate substrate 2 can be limited and fixed by manually pressing the anode plate substrate 2 or other positioning devices to prevent the anode plate substrate 2 from moving.

[0022] Preferably, the protective coating is a noble metal oxide (such as oxides of ruthenium, iridium, titanium) or other corrosion-resistant materials.

[0023] After the protective coating is cured, a protective coating will be formed on the hole wall of the perforation of the anode plate substrate 2. The noble metal oxide (such as ruthenium, iridium, titanium oxides) coating has chemical inertness and can form a dense protective layer to isolate the direct contact between the corrosive medium and the substrate, significantly extending the service life of the anode plate in a strong corrosion environment. At the same time, the noble metal oxide coating (such as iridium oxide) has a stable crystal structure and can be tightly combined with the anode plate substrate 2, reducing the coating peeling caused by mechanical stress or electrolyte scouring. The denseness of the coating can also prevent the electrolyte from penetrating into the matrix and avoid the matrix deformation or fracture caused by corrosion expansion.

[0024] To improve the spraying uniformity and avoid coating defects caused by impurity attachment, preferably, the nozzle 17 is an atomizing nozzle 17.

[0025] Refer to Figures 1 - 5 As shown in [reference number], the driving mechanism 8 is installed on the mounting seat 7, and the driving mechanism 8 is used to drive the punch 6 to rotate during the return stroke. Preferably, the mounting seat 7 includes a top plate 71, side plates 72 and a bottom plate 73. The top plate 71 is connected to the output shaft of the cylinder 5. The side plates 72 are fixed on the opposite sides below the top plate 71. The bottom plate 73 is located below the top plate 71 and fixed between the two side plates 72. The top plate 71, the bottom plate 73 and the two side plates 72 enclose a rectangular frame, and the driving mechanism 8 is located inside the rectangular frame. The driving mechanism 8 includes a motor 81, a first gear 83 and a second gear 84. The motor 81 is installed on the side plate 72. A rotating shaft 82 is fixed on the output shaft of the motor 81. The rotating shaft 82 is vertically arranged, with one end fixed to the output shaft of the motor 81 and the other end fixed to the center of the first gear 83. The second gear 84 is located on one side of the first gear 83 and meshes with the first gear 83. The first gear 83 and the second gear 84 are both located on the bottom plate 73 and are respectively rotationally matched with the upper surface of the bottom plate 73. Specifically, a circular groove 211 is provided around the center on the bottom surfaces of the first gear 83 and the second gear 84. Two sliders are provided on the upper surface of the bottom plate 73, which are respectively adapted to the circular grooves 211 on the bottom surfaces of the first gear 83 and the second gear 84. The sliders are embedded in the corresponding grooves 211 and are slidably matched with the grooves 211. The upper end of the punch 6 passes through the bottom plate 73 and is fixed to the center of the second gear 84. A connecting rod 11 is fixed below the top plate 71. The upper end of the connecting rod 11 is fixed to the top plate 71, and the lower end is inserted into the center of the second gear 84. The central axis of the punch 6 coincides with the central axes of the second gear 84 and the connecting rod 11.

[0026] In the above technical solution, the punch 6 of the present invention includes two strokes. The first stroke is when the punch 6 moves downward. At this time, only the cylinder 5 needs to be controlled to move the punch 6 downward. The purpose of this process is to punch the anode plate substrate 2 on the base 1 to form one or more through holes in the anode plate substrate 2. The second stroke is the return stroke, that is, when the punch 6 moves upward. At this time, not only the cylinder 5 needs to be controlled to move the punch 6 upward, but also the motor 81 needs to be started so that the punch 6 rotates at a high speed during the return stroke, so that the spray head 17 can evenly spray the protective coating on the inner wall of the through hole. During the return stroke, the cylinder 5 and the motor 81 are started successively or simultaneously. When the cylinder 5 is started, the mounting seat 7, the driving mechanism 8 and the punch 6 will move upward synchronously. When the motor 81 is started, the first gear 83 will start to rotate. Since the second gear 84 is meshed with the first gear 83 and the punch 6 is fixedly centered with the second gear 84, when the first gear 83 rotates, the second gear 84 and the punch 6 will rotate synchronously around their central axes. In this way, the spray head 17 can rotate and spray in the through hole along with the punch 6, so that the inner wall of the through hole is evenly covered with the protective coating.

[0027] Referring to Figures 1 - 7 , a liquid spraying channel 15 is arranged in the punch 6. The liquid spraying channel 15 is connected to the external protective coating supply system, and the spray head 17 is communicated with the liquid spraying channel 15. The liquid spraying channel 15 includes an arc section, a vertical section and a horizontal section which are connected in sequence from top to bottom. The vertical section is located on the central axis of the punch 6. One end of the horizontal section is communicated with the vertical section, and the other end extends to the outside of the punch 6. A liquid inlet pipe 13 is arranged on one side above the punch 6 or on the second gear 84. One end of the arc section is communicated with the vertical section, and the other end is communicated with the liquid inlet pipe 13. The liquid inlet pipe 13 is used to be connected to the external protective coating supply system.

[0028] It should be noted that the external protective coating supply system is a prior art, so the specific structure and working principle of the external protective coating supply system will not be described in detail in the present invention.

[0029] Preferably, the punch 6 includes an upper punch 61 and a lower punch 62. The upper punch 61 and the lower punch 62 are integrally formed. The lower punch 62 is conical, and the upper punch 61 is cylindrical. The outer surfaces of the upper punch 61 and the lower punch 62 are both smooth.

[0030] The conical lower punch 62 in the present invention can guide the gradual deformation of the anode plate substrate 2, reduce the resistance of material flow during stamping, reduce the stress concentration on the punch 6, and extend the service life. In addition, the conical structure can achieve self-positioning and guiding when contacting the material, reducing the hole position deviation caused by offset during the stamping process. The design of the cylindrical upper punch 61 can ensure the stability of the punch 6 moving in the vertical direction, avoid vibration or inclination caused by irregular shape, and ensure the perpendicularity of the punched hole. The smooth outer surfaces of the upper punch 61 and the lower punch 62 can reduce the friction coefficient between the punch 6 and the anode plate substrate 2, reduce the risk of adhesion or scratching of material debris and protective coatings, and improve the demolding efficiency at the same time.

[0031] To prevent noble metal oxides (such as ruthenium, iridium, titanium oxides) or other corrosion-resistant materials from adhering to the surface of the punch 6 and avoid contamination of the punch 6, further, in this embodiment, low surface energy materials such as polytetrafluoroethylene (PTFE) are sprayed on the surfaces of the upper punch 61 and the lower punch 62, and their excellent anti-adhesion and chemical inertness are utilized to reduce the adhesion of coatings.

[0032] In the present invention, for the punch 6 to perform downward punching, there must be no other parts protruding outward from the surface of the punch 6. Therefore, the spray head 17 must be hidden on one side of the punch 6. For this purpose, the present invention provides a receiving groove 20 for receiving the spray head 17 at the outlet end of the horizontal section of the liquid spraying channel 15, and the receiving groove 20 is located on one side of the lower punch 62.

[0033] The spray head 17 is received in the receiving groove 20. Although this design can protect the spray head 17 and avoid obstacles when the punch 6 performs downward punching, it will affect the liquid spraying of the spray head 17, resulting in the spray head 17 being unable to spray the protective coating onto the hole wall in a divergent manner, and a large amount of protective coating will be sprayed on the surface of the punch 6. To solve this problem, the present invention is provided with a fixed pipe 18, a movable pipe 19 and a spring-back mechanism for driving the movable pipe 19 and the spray head 17 to reset when the punch 6 stops rotating in the liquid spraying channel 15.

[0034] Preferably, both the fixed pipe 18 and the movable pipe 19 are used for transporting the protective coating. The movable pipe 19 is horizontally arranged and sleeved on the outer surface of the fixed pipe 18, and the spray head 17 is installed at the end of the movable pipe 19. The fixed pipe 18 is fixed in the horizontal section of the liquid spraying channel 15, and the movable pipe 19 is located in the horizontal section of the liquid spraying channel 15. Specifically, one end of the fixed pipe 18 is fixed to the inner wall around the horizontal section of the liquid spraying channel 15, and the other end is inserted into the movable pipe 19.

[0035] In the above technical solution, when the punch 6 moves upward and rotates, under the action of centrifugal force, the movable tube 19 and the nozzle 17 will move outward. At this time, the nozzle 17 will be thrown out of the receiving groove 20. After the nozzle 17 leaves the receiving groove 20, the nozzle 17 is located between the lower punch 62 and the hole wall and the nozzle 17 faces the hole wall. Therefore, the protective coating can be well sprayed on the hole wall, avoiding the protective coating from adhering to the surface of the lower punch 62.

[0036] Further preferably, there are two elastic return mechanisms, which are symmetrically arranged on the opposite sides of the movable tube 19. The elastic return mechanism includes a groove 211, a fixing plate 213 and a spring 212. The groove 211 is opened on the inner side of the horizontal section of the liquid spraying channel 15. The fixing plate 213 is located in the groove 211 and is slidably matched with the groove 211. The fixing plate 213 is fixed at the other end of the movable tube 19 relative to the nozzle 17. The spring 212 is located in the groove 211 and one end is connected to the fixing plate 213, and the other end is connected to the side wall of the groove 211. The length direction of the spring 212 is consistent with the length direction of the movable tube 19.

[0037] In the above technical solution, when the punch 6 moves upward and rotates, under the action of centrifugal force, the movable tube 19 and the nozzle 17 will move outward. At this time, the nozzle 17 will be thrown out of the receiving groove 20, and the spring 212 is in a compressed state. When the punch 6 stops rotating, under the reset action of the spring 212, the movable tube 19 and the nozzle 17 will move in the reverse direction again. At this time, the nozzle 17 will automatically return to the receiving groove 20. In the present invention, the nozzle 17 is moved out of the receiving groove 20 by centrifugal force and is reset by the spring 212, which can be realized without relying on other power components, with a simple structure and low cost.

[0038] Refer to Figures 1 - 7 , a jet channel 14 is arranged in the punch 6, and the jet channel 14 is used to convey nitrogen gas at a temperature of -20 to 20 °C. An air outlet hole 16 is arranged on the jet channel 14. The air outlet hole 16 is located on one side of the lower punch 62 and directly above the receiving groove 20. The axis of the air outlet hole 16 is inclined downward at an angle of 20 - 40° with the horizontal direction.

[0039] In the above technical solution, when the spray head 17 sprays the coating onto the perforated hole wall, the coating will return upward and contact the surface of the punch 6, resulting in a large amount of coating adhering to the surface of the punch 6. Therefore, in the present invention, a dynamic air flow barrier is provided above the spray head 17. Nitrogen is blown out through the air outlet 16, and an air flow inclined downward at an angle of 20-40° with the horizontal direction will be formed, thereby forming a directional air flow barrier around the spray head 17. The air flow is used to block the diffusion path of the coating particles and prevent them from floating upward. In addition, after the anode plate substrate 2 is punched, debris will adhere to the inner wall of the perforation. If the debris is not removed, it will affect the adhesion of the coating. Therefore, in the present invention, the air outlet 16 is arranged above the spray head 17. After the nitrogen is blown out through the air outlet 16, the debris adhering to the inner wall of the perforation will be blown off first, which is convenient for the adhesion of the protective coating and improves the coating quality.

[0040] Preferably, the jet channel 14 is spirally arranged in the upper punch 61 and the lower punch 62, and the jet channel 14 is close to the outer surfaces of the upper punch 61 and the lower punch 62. The jet channel 14 is used to connect with the external air supply system. Specifically, an air inlet pipe 12 is arranged on one side above the punch 6 or on the second gear 84. The air inlet pipe 12 is connected with the external air supply system, and the upper end of the jet channel 14 is communicated with the air inlet pipe 12.

[0041] In the above technical solution, when the punch 6 punches a hole, the temperature of the punch 6 will rise. In order to reduce the temperature of the punch 6, the jet channel 14 in the present invention is arranged in a spiral downward manner and is close to the outer layer of the punch 6. When low-temperature nitrogen passes through the jet channel 14, it will cool the punch 6, thereby reducing the temperature of the punch 6. To sum up, the functions of the jet channel 14 in the present invention are as follows: First, it can blow the debris on the hole wall to improve the spraying quality; second, it can form an air curtain protection effect to prevent the coating from returning upward; third, it can quickly cool the punch 6.

[0042] It should be noted that the external air supply system is a prior art, so the specific structure and working principle of the external air supply system will not be described in detail in the present invention.

[0043] It should be noted that nitrogen can be replaced by other gases, such as air, oxygen, etc. Nitrogen is not easy to react with the anode plate substrate 2.

[0044] Further preferably, a material receiving hopper 9 is arranged on the base 1. The anode plate substrate 2 is placed above the material receiving hopper 9, and a discharge port 10 is arranged at the bottom of the material receiving hopper 9.

[0045] In the above technical solution, the arrangement of the material receiving hopper 9 is convenient for the punch 6 to pass through the anode plate substrate 2 during punching on the one hand, and is convenient for receiving the debris generated by punching on the other hand.

[0046] It should be noted that the jet channel 14 can be processed by a dedicated auger drilling device, and the liquid spraying channel 15 can be processed by a multi-axis numerical control machine tool, specifically a five-axis linkage numerical control machine tool, and the drill bit is controlled to feed along a preset curved path through programming (such as circular interpolation function, etc.).

[0047] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications should also be regarded as the protection scope of the present invention.
