Description

Technical Field

[0001] The present invention relates to the technical field of metal tube manufacturing, in particular to a manufacturing device and a manufacturing method for producing high-quality metal tubes with small diameters. Background Art

[0002] Micro-diameter metal pipes usually refer to metal pipes with smaller diameters. Currently, micro-diameter metal pipes are mostly prepared by electroforming, which uses a conductive wire as the cathode, a metal mesh as the anode, and a metal salt solution as the electroforming liquid. The specific operation is to clamp the conductive wire, energize it, and place it in the electroforming liquid. The power is turned on to reduce the metal ions in the metal salt solution and attach them to the conductive wire, gradually forming the tube wall, and finally the tube is obtained after the conductive wire is pulled out; However, the chuck and the conductive wire are connected in an active manner. When the size of the metal tube to be prepared is short, in order to ensure the stability of the electroforming process, the chuck needs to be extended into the electroforming pool so that the electroforming area is located in the pool. In this case, the electroforming liquid can easily invade the inside of the chuck, resulting in uneven edges of the formed metal tube. Secondly, the conductive wire is clamped by the tensioner and rotates in the electroforming liquid. However, the distance between the fastening point of the tensioner and the electroforming liquid is relatively far, which causes the conductive wire to face greater resistance in the electroforming liquid and increase the moment of inertia. In the liquid environment, the conductive wire is very likely to shake due to the liquid resistance, making it difficult to maintain a stable rotation speed, affecting the uniform forming of the metal tube. In view of this, there is an urgent need for a manufacturing device and a manufacturing method for producing high-quality micro-diameter metal tubes to solve the above problems. Summary of the invention

The clamping mechanism includes an extrusion piece, and the extrusion piece is used to clarify the connection point between the conductive wire and the clamping mechanism. At the same time, the clamping mechanism can adjust the fastening point of the conductive wire according to the length of the metal tube prepared as needed.

[0005] As a further improvement of the present technical solution, the casting pool mechanism also includes an input pipe and an output pipe installed on the surface of the outer pool, the input pipe and the output pipe are used to transport the metal salt solution, a pump body is installed at the bottom of the inner wall of the outer pool, the output end of the pump body is connected to the interior of the inner pool, and overflow grooves are opened on the top of both sides of the inner pool.

[0006] As a further improvement of the present technical solution, the driving mechanism includes a driving motor fixedly mounted on the top of the supporting frame, connecting components are fitted on the bottom ends of both sides of the fixed strip, the bottoms of the two connecting components are fitted on the surface of the outer pool, the output shaft of the driving motor is connected to one end of the pulley group, the other end of the pulley group is fixedly connected to the rotating shaft, and the two sides of the rotating shaft are respectively connected to the two connecting components.

[0008] As a further improvement of the present technical solution, two clamping mechanisms are provided, and the clamping mechanisms also include a rotating tube, a threaded rod and a tensioning rod. The rotating tube, the threaded rod and the tensioning rod are all hollow structures. The rotating tube is coaxially connected to the second connecting gear. An energized inner rod is provided inside the rotating tube. The rotating tube, the threaded rod and the tensioning rod are threadedly sealed and connected. The extrusion piece is located at the end of the tensioning rod away from the threaded rod.

[0009] As a further improvement of the technical solution, the extrusion member includes a slip ring, an extrusion bag is fixedly installed on the side of the tension rod away from the threaded rod, and an extrusion cavity is opened at one end of the extrusion bag close to the inside of the tension rod.

[0010] As a further improvement of the technical solution, a sliding groove is provided on the inner wall of one end of the tensioning rod close to the extrusion bag, a slider is slidingly provided inside the sliding groove, the surface of the slider is connected to the inner wall of the sliding groove by an elastic member, and one side of the slider extending out of the sliding groove is fixedly mounted on the outer wall of the slip ring.

[0011] As a further improvement of the technical solution, a rounded edge is provided at the opening of the inner pool.

[0012] The second object of the present invention is to provide a manufacturing method for operating the manufacturing device for producing high-quality micro-diameter metal tubes, comprising the following method steps: S1. First, place the anode metal mesh stably inside the inner tank, determine the length of the prepared metal tube, and select the conductive wire of appropriate size; S2, then, separate the two sets of rotating tubes, threaded rods and tensioning rods, and pass the two ends of the cathode conductive wire through the two threaded rods and the two tensioning rods respectively; S3, inserting the two ends of the cathode conductive wire into the inside of the two energized inner rods respectively, and then threading the two threaded rods into the ends of the two rotating tubes respectively; S4, inserting two tensioning rods into the surfaces of the two threaded rods respectively, and rotating the tensioning rods, with the rotation of the tensioning rods, the threaded rods extend into the interior of the tensioning rods; S5. As the threaded rod is extended, the threaded rod squeezes the slip ring, forcing the slip ring to slide into the extrusion bag, so that the extrusion bag expands near one end of the tensioning rod, and the other end of the extrusion bag is combined to seal the opening of the tensioning rod, and at the same time, the conductive wire can be tightened; S6, transporting the metal salt solution to the inside of the outer pool through the input pipe, and starting the pump body at the same time, transporting the metal salt solution inside the outer pool to the inside of the inner pool, as the metal salt solution inside the inner pool rises, it will overflow the inner pool, causing the metal salt solution to fall into the inside of the outer pool again, and the cycle will repeat; S7, start the driving motor, the rotational force generated by the driving motor is transmitted to the rotating shaft by means of the pulley set, and then, through the connecting assembly, the rotational force is further transmitted to the rotating tube, so that the rotating tube drives the conductive wire to rotate inside the inner pool under the coordinated action of the threaded rod and the tensioning rod; S8. Finally, the power is turned on. The metal ions in the metal salt solution undergo a reduction reaction under the power-on environment and adhere to the surface of the conductive wire. As time goes by, the tube wall structure is gradually constructed. Finally, after the conductive wire is pulled out, the desired tube is obtained.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the manufacturing device and manufacturing method for producing high-quality micro-diameter metal tubes, by rotating the tension rod, the threaded rod is driven to gradually extend into the tension rod, and the thrust generated thereby acts on the slip ring, so that the other end of the slip ring can be smoothly embedded in the extrusion bag. While the extrusion bag is subjected to force, it relies on its own elastic characteristics to achieve a double clamping effect on the conductive wire. This method effectively reduces the possibility of the metal salt solution entering the tension rod during the rotation of the clamping device in the inner pool, thereby improving the flatness of the end of the formed metal tube; At the same time, when the extrusion bag is squeezed and relies on its own elasticity, it can firmly clamp the conductive wire. When the clamping component rotates, it can drive the conductive wire to rotate synchronously in the inner pool. Compared with the method of clamping the edge of the conductive wire in the prior art, this clamping can effectively reduce the rotational inertia of the conductive wire, thereby enabling the conductive wire to overcome the liquid resistance in the electroforming liquid and achieve more stable rotation, which is beneficial to improving the forming quality and production efficiency of small-diameter metal tubes.

DETAILED DESCRIPTION

[0016] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 As shown, the purpose of this embodiment is to provide a manufacturing device for producing high-quality small-diameter metal tubes, including a device body 1, the device body 1 includes a casting pool mechanism 11, the casting pool mechanism 11 includes an outer pool 111 and an inner pool 112, the inner pool 112 is suspended inside the outer pool 111, the top of the inner pool 112 is higher than the top of the outer pool 111, a support frame 12 is fixedly installed on the top of the outer pool 111, a fixed strip 13 is installed on the lower end surface of the support frame 12, an anode metal mesh 14 is movably placed inside the inner pool 112, a driving mechanism 2 is installed on the surface of the support frame 12, and a clamping mechanism 3 for clamping the cathode conductive wire is arranged at the other end of the driving mechanism 2, the clamping mechanism 3 includes an extrusion 34, the extrusion 34 is used to clarify the connection point between the conductive wire and the clamping mechanism 3, and at the same time, the clamping mechanism 3 can adjust the fastening point of the conductive wire according to the length of the metal tube to be prepared.

[0018] When a metal tube is prepared by electroforming, an electroforming liquid is indispensable. In this scheme, a metal salt solution is selected as the electroforming liquid, and the metal salt solution can be transported through a casting pool mechanism 11. The specific structure of the casting pool mechanism 11 is disclosed below. The casting pool mechanism 11 also includes an input pipe 113 and an output pipe 114 installed on the surface of an outer pool 111. The input pipe 113 and the output pipe 114 are used to transport the metal salt solution. A pump body 115 is installed at the bottom of the inner wall of the outer pool 111. The output end of the pump body 115 is connected to the interior of the inner pool 112. Overflow grooves 116 are provided on the tops of both sides of the inner pool 112.

[0019] See also Figure 2 As shown, the input pipe 113 is used to inject fresh metal salt solution into the outer pool 111, such as delivering the solution for the first time or replenishing the solution consumed or reduced due to other reasons during the electroforming process, to ensure that the total amount and concentration of the electroforming solution can be maintained at an appropriate level, and the output pipe 114 is used to output the metal salt solution in the casting pool, such as when it is necessary to replace the solution, adjust the solution composition ratio, or discharge the treated solution; It should be noted that the total capacity of the metal salt solution in the outer tank 111 and the inner tank 112 needs to be greater than the capacity of the inner tank 112, so that the solution can overflow in the inner tank 112, and the overflowed solution is then pumped back to the inner tank 112 by the pump body 115, thereby forming a reciprocating solution supply mode, which not only ensures the fluidity and uniformity of the solution, but also maintains the stability of the electroforming environment.

[0020] During the preparation of the metal tube, the cathode conductive wire needs to be clamped by the clamping mechanism 3, and the driving mechanism 2 is used to drive it to rotate inside the inner pool 112. First, the specific structure of the driving mechanism 2 is disclosed. The driving mechanism 2 includes a driving motor 22 fixedly installed on the top of the support frame 12, and the bottom ends of both sides of the fixed strip 13 are fitted with connecting components 21, and the bottoms of the two connecting components 21 are fitted on the surface of the outer pool 111. The output shaft of the driving motor 22 is connected to one end of the pulley group 23, and the other end of the pulley group 23 is fixedly connected to the rotating shaft 24. The two sides of the rotating shaft 24 are respectively connected to the two connecting components 21.

[0021] The two connecting components 21 each include a supporting frame plate 211 , and the supporting frame plate 211 is internally rotatably provided with a first connecting gear 212 and a second connecting gear 213 . The first connecting gear 212 is meshed with the second connecting gear 213 , and both ends of the rotating shaft 24 are coaxially connected to the two first connecting gears 212 .

[0022] Secondly, the specific structure of the clamping mechanism 3 is disclosed. There are two clamping mechanisms 3, which also include a rotating tube 31, a threaded rod 32 and a tensioning rod 33. The rotating tube 31, the threaded rod 32 and the tensioning rod 33 are all hollow structures. The rotating tube 31 is coaxially connected to the second connecting gear 213. An energized inner rod 311 is arranged inside the rotating tube 31. The rotating tube 31, the threaded rod 32 and the tensioning rod 33 are threadedly sealed. The extrusion piece 34 is located at the end of the tensioning rod 33 away from the threaded rod 32.

[0023] The extrusion member 34 includes a slip ring 341 . An extrusion bag 342 is fixedly mounted on one side of the tension rod 33 away from the threaded rod 32 . An extrusion cavity 343 is defined at one end of the extrusion bag 342 close to the tension rod 33 .

[0024] A groove 42 is provided on the inner wall of one end of the tensioning rod 33 close to the extrusion bag 342, and a slider 4 is slidably provided inside the groove 42. The surface of the slider 4 is connected to the inner wall of the groove 42 through an elastic member 41. The slider 4 extends out of the groove 42 and is fixedly mounted on the outer wall of the slip ring 341.

[0025] Combination Figure 3 As shown, the selected conductive wire length needs to be longer than the inner pool 112, see Figure 4Before installing the conductive wire, separate the rotating tube 31, the threaded rod 32 and the tension rod 33 in a threaded connection state by rotating, and then, respectively pass the two ends of the cathode conductive wire through the two threaded rods 32 and the two tension rods 33, and accurately insert the two ends of the cathode conductive wire into the two energized inner rods 311. After completing the above steps, the two threaded rods 32 are respectively fixed to the ends of the two rotating tubes 31 in the form of threaded connection. At this point, the threaded rod 32 is installed. Then, the two tension rods 33 are respectively inserted into the two threaded rods 32. The tension rod 33 is then rotated. During the rotation of the tension rod 33, the threaded rod 32 gradually extends into the tension rod 33. As the threaded rod 32 extends, the threaded rod 32 pushes the slip ring 341, so that the other end of the slip ring 341 is squeezed into the extrusion cavity 343 of the extrusion capsule 342, thereby causing the end of the extrusion capsule 342 close to the tension rod 33 to expand. During the sliding process of the slip ring 341, the slider 4 can slide in the slide groove 42 provided on the inner wall of the tension rod 33, thereby improving the sliding stability of the slip ring 341. The extrusion bag 342 is made of elastic material (preferably insulating rubber). Figure 5 It can be seen that, because it has a certain sealing property, the conductive wire can be initially sealed. Figure 6 As shown, on this basis, as one end of the extrusion bag 342 close to the tensioning rod 33 expands due to the action of the internal structure, the conductive wire can be further sealed to achieve a double sealing effect. When the metal tube is relatively short, the metal salt solution can greatly reduce the chance of entering the tensioning rod 33 during the rotation of the tensioning rod 33 in the inner pool 112, thereby improving the flatness and quality stability of the end of the formed metal tube.

[0026] Back to Figure 3 After the conductive wire is installed, it will be located at the upper end of the inner cavity of the inner tank 112, and then the metal salt solution is transported to the inner tank 112 and the outer tank 111 through the input pipe 113. Fig.10It can be seen that when the driving motor 22 is started, the output shaft of the driving motor 22 drives one end of the pulley group 23 connected thereto to start rotating. The pulley group 23 is composed of two pulleys and a belt, wherein one pulley is fixedly connected to the output shaft of the driving motor 22, and the other pulley is installed on the surface of the rotating shaft 24. The rotating shaft 24 is rotated by the belt tension transmission. Since the two ends of the rotating shaft 24 are respectively connected to the first connecting gear 212, when the rotating shaft 24 rotates, it will drive the two first connecting gears 212 to rotate synchronously in the supporting frame plate 211, and then drive the second connecting gear 213 to rotate through the meshing relationship. The two second connecting gears 213 are respectively coaxially connected to the rotating tube 31, so when the second connecting gear 213 rotates, the rotating tube 31 will rotate accordingly. Because the rotating tube 31, the threaded rod 32 and the tensioning rod 33 are threadedly sealed, the tensioning rod 33 will also rotate in coordination with the rotation of the rotating tube 31. Therefore, it can drive the conductive wire to rotate inside the inner pool 112 for uniform electroforming.

[0027] During the electroforming process, the expansion seal generated by the change in the internal structure of the extrusion capsule 342 can be used as a clamping point for the conductive wire. Compared with the traditional method of clamping the edge of the conductive wire, the clamping point formed by the expansion of the extrusion capsule 342 is closer to the middle end of the conductive wire, which can make the clamping force on the conductive wire more concentrated, so that the mass distribution of the conductive wire is mainly concentrated in the area near the clamping point, thereby reducing the rotational inertia of the conductive wire; The diameter of the conductive wire is relatively small. When it is in the electroforming liquid environment, the lower moment of inertia makes it easier to overcome the resistance of the metal salt solution, thereby ensuring that the conductive wire can rotate stably and continuously in the inner pool 112. In the preparation of small-diameter metal tubes, the stable rotation of the conductive wire plays an extremely critical role. It can ensure that the metal ions are evenly deposited and reduced on the surface of the conductive wire, so that the thickness of the wall of the metal tube finally formed is uniform, which greatly improves the forming quality of the metal tube.

[0028] See also Figure 4 Combined with Figure 5 As shown, the rotating tube 31 and the threaded rod 32 are connected by threads. The threaded rod 32 and the tensioning rod 33 need to be rotated and extended to a certain position so that the extrusion piece 34 can perform secondary sealing on the conductive wire. Therefore, if the size of the metal tube to be prepared is relatively short, the distance between the rotating tube 31 and the threaded rod 32 can be adjusted to achieve the distance between the two extrusion pieces 34, thereby ensuring that the conductive wire area of ​​the electroformed metal tube can be located in the middle of the inner pool 112, creating favorable conditions for uniform electroforming of the metal tube, and effectively improving product quality and process stability.

[0029] The cross-section of the end of the slip ring 341 close to the extrusion bag 342 is smaller than the cross-section of the end close to the tensioning rod 33 (not shown in the figure). The extrusion piece 34 is controlled by the rotation between the threaded rod 32 and the tensioning rod 33, so that conductive wires of different diameters can be sealed and clamped. In addition, the end angle cross-section of the slip ring 341 in contact with the extrusion bag 342 is smaller, which improves the accuracy of the sliding insertion of the slip ring 341.

[0030] The above-mentioned energized inner rod 311 is equipped with its own power supply and is in a wireless state. When the conductive wire contacts the energized inner rod 311, due to the existence of the power supply, the electric energy can be transmitted from the energized inner rod 311 to the conductive wire, thereby realizing the energizing function of the conductive wire. During the operation of the device, the energized inner rod 311 is coaxially connected with the rotating tube 31. When the rotating tube 31 rotates, it will drive the energized inner rod 311 to rotate together, ensuring that during the entire dynamic operation process, even if the conductive wire is in a rotating state, it can continue to stably maintain good contact with the energized inner rod 311, effectively reducing the power outage caused by poor contact due to rotation or the falling off of the conductive wire, and ensuring the stability and continuity of the current supply in the electroplating process.

[0031] After the electroforming is completed, the driving motor 22 and the pump body 115 stop running, and the anode metal mesh 14 and the energized inner rod 311 stop supplying power. In view of the small diameter of the conductive wire, in the processing stage after the electroforming is completed, the conductive wire can be cut at the end position of the two extrusion bags 342. After the cutting is completed, the conductive wire with the electroformed tube wall is taken out for subsequent work. Subsequently, the tension rod 33, the threaded rod 32 and the rotating tube 31 are rotated. By rotating the tension rod 33, the elastic member 41 (preferably The spiral spring member) rebounds and resets, driving the slip ring 341 to slide out of the extrusion cavity 343, releasing the tension and sealing state of the remaining conductive wire, and then rotating the threaded rod 32 to adjust the relative position relationship between it, the tension rod 33 and the rotating tube 31, and further loosen the clamping and fixation of the conductive wire. Under the coordinated action of this series of rotation actions, the remaining conductive wire originally fixed in the corresponding position can be released, so that it can be easily taken out of the device, so as to recycle the conductive wire or prepare for the next round of electroforming operation.

[0032] In addition, cutting the electroformed part of the conductive wire while it is clamped can keep the position of the metal tube relatively stable after forming, avoid deformation of the metal tube due to loss of constraint of the conductive wire, and help maintain the regularity of the end of the metal tube. Secondly, cutting the conductive wire in the clamped state can accurately control the position where the metal tube and the conductive wire are separated, ensuring that the length of the metal tube meets the expected specifications, thereby improving the quality and efficiency of the preparation and forming of small-diameter metal tubes as a whole.

[0033] It should be noted that: due to the small diameter of the conductive wire, the amount of material required during use is relatively small, and it uses relatively common materials, which are usually widely available and relatively low in cost. Whether it is a small amount of loss during the production process or the need to replace the conductive wire in some special circumstances, it will not cause a large economic loss or waste of resources due to the scarcity or high cost of materials. The selection of materials ensures the economy and sustainability of the process.

[0034] During the electroforming process, the metal salt solution needs to circulate between the inner pool 112 and the outer pool 111 , and the shape of the opening of the inner pool 112 easily hinders the flow of the solution. Therefore, a rounded edge 5 is provided at the opening of the inner pool 112 .

[0035] See also Figure 7 As shown, a rounded edge 5 is provided at the opening of the inner pool 112. The design of the rounded edge 5 can make the solution transition more naturally during the flow process, reduce flow resistance, and reduce irregular liquid flow, thereby improving the efficiency of the metal salt solution circulation system in the entire electroforming device.

[0036] The metal salt solution continuously overflows from the inner tank 112 and circulates to the outer tank 111 and then returns to the inner tank 112. This continuous circulation process can effectively stabilize the concentration of metal ions. During electroforming, the metal ions undergo a reduction reaction around the conductive wires in the inner tank 112 to form a metal tube wall. If the metal ion concentration fluctuates greatly, it will lead to uneven deposition of the tube wall, which is prone to problems such as uneven thickness, uneven density and even local defects. A stable metal ion concentration can ensure that the metal is evenly and continuously deposited on the surface of the conductive wire, so that the quality indicators of the produced pipes in terms of wall thickness, density, strength and other aspects can be well guaranteed, thereby effectively improving the overall quality level of the produced pipes and ensuring the stability and reliability of the products.

[0037] The threaded rod 32 and the tension rod 33 are both made of insulating material (such as ceramic or surface-coated with insulating material).

[0038] Embodiment 2: This embodiment is based on the content provided in Embodiment 1, and aims to provide a manufacturing method for a manufacturing device for producing high-quality micro-diameter metal tubes. The specific steps are as follows: Step 1: First, place the anode metal mesh 14 stably inside the inner tank 112, determine the length of the prepared metal tube, and select a conductive wire of appropriate size; Step 2: Then, separate the two sets of rotating tubes 31, threaded rods 32 and tension rods 33, and pass the two ends of the cathode conductive wire through the two threaded rods 32 and the two tension rods 33 respectively; Step 3: Insert the two ends of the cathode conductive wire into the two energized inner rods 311 respectively, and then thread the two threaded rods 32 into the ends of the two rotating tubes 31 respectively; Step 4: insert the two tension rods 33 into the surfaces of the two threaded rods 32 respectively, and rotate the tension rods 33. As the tension rods 33 rotate, the threaded rods 32 extend into the interior of the tension rods 33; Step 5: As the threaded rod 32 is inserted, the threaded rod 32 squeezes the slip ring 341, forcing the slip ring 341 to slide into the extrusion bag 342, so that the end of the extrusion bag 342 close to the tensioning rod 33 expands, and the other end of the extrusion bag 342 is combined to seal the opening of the tensioning rod 33, and at the same time, the conductive wire can be tightened at this time; Step 6: The metal salt solution is transported to the inside of the outer pool 111 through the input pipe 113, and the pump body 115 is started at the same time to transport the metal salt solution in the outer pool 111 to the inside of the inner pool 112. As the metal salt solution in the inner pool 112 rises, it overflows the inner pool 112, causing the metal salt solution to fall into the inside of the outer pool 111 again, and the cycle repeats; Step 7: Start the drive motor 22. The rotational force generated by the drive motor 22 is transmitted to the rotating shaft 24 by means of the pulley set 23. Then, the rotational force is further transmitted to the rotating tube 31 through the connecting assembly 21. Then, the rotating tube 31 drives the conductive wire to rotate inside the inner pool 112 under the coordinated action of the threaded rod 32 and the tensioning rod 33. Step 8. Finally, turn on the power supply. The metal ions in the metal salt solution undergo a reduction reaction under the power supply environment and adhere to the surface of the conductive wire. As time goes by, the tube wall structure is gradually constructed. Finally, after the conductive wire is pulled out, the desired tube is obtained.
