Description

Technical Field

[0001] This application relates to the field of additive manufacturing technology, and in particular to a multi-wire hub disk and a multi-wire switcher. Background Technology

[0002] Additive manufacturing technology transforms a digital model into a physical entity by stacking materials layer by layer. It enables rapid prototyping, the manufacture of complex structures, improved material utilization, and also supports personalized customization.

[0003] The wire feeder is a key component in wire-feed additive manufacturing. It uses a drive motor to move the wire feeding wheel and deliver the filamentous material to the wire exit nozzle. To meet the needs of multi-material composite additive manufacturing of the same workpiece, it is necessary to frequently switch between different types of wire. Nowadays, the field of arc welding generally uses traditional dual-wire welding equipment, which has two wire exit nozzles installed on a single specially designed tool end. Each wire exit nozzle corresponds to a multi-wire feeding method of a wire feeder. The wire switching speed is fast, but each switch requires left and right movement, and recalibration is required after the switch.

[0004] In the field of laser additive manufacturing, existing designs connect multiple wire feeders and nozzles via multiple branch pipes and a main pipe. Each wire feeder is connected to a branch pipe, all branch pipes connect to the main pipe, and the main pipe connects to the nozzle. While this design allows for multi-wire switching, the operation of the wire feeders themselves and other equipment can cause fluctuations in wire feeding stability. Exposed pipes lack protective structures and are prone to unexpected bending or deformation under external forces such as equipment vibration and operational collisions. Fluctuations in wire feeding can even cause wire jamming, disrupting the stability of the weld joint's molten wire volume. Ultimately, this leads to defects in the additive layer, such as uneven line thickness and material shortages, and may even cause breakage, affecting normal operation. Utility Model Content

[0005] To achieve stable switching and conveying of multi-filament materials, this application provides a multi-filament hub plate and a multi-filament switcher.

[0006] This application provides a multi-wire hub plate. The technical solution adopted is as follows:

[0007] A multi-filament hub disc includes a hub housing with several guide channels inside. The guide channels are used to guide the filaments so that the filaments can be output from the same direction after being input from different directions.

[0008] By adopting the above technical solutions, the guide channel provides a stable conveying path for the wire, avoiding fluctuations in the conveying of the wire on a single pipe, reducing wire feeding jams caused by fluctuations, and improving the stability of wire conveying; the hub shell forms a physical barrier to prevent operators or other factors from directly contacting the channel, protecting the wire and improving the safety of equipment operation; multiple guide channels are integrated according to a preset layout, and the hub shell serves as a unified carrier, which can make the wire conveying system compact and optimize space utilization efficiency;

[0009] The multi-filament hub can gather filaments from different positions and output them in a single direction. Its output end is connected to the single-filament tool end to realize the switching of multiple filaments. While increasing the number of filament feeders, it maintains a single output end and ensures that the position of the filament outlet remains unchanged after the filament is switched, avoiding the tedious steps of recalibration.

[0010] Optionally, the hub housing is a detachable structure, comprising at least two detachably connected housing units. Each housing unit has a guide groove. When two opposing housing units are closed, the guide grooves on the two opposing housing units cooperate to form a guide channel for the wire to pass through.

[0011] By adopting the above technical solution, the detachable housing unit design allows for easy assembly by simply closing the housing unit. When the multi-wire hub plate becomes blocked or needs maintenance, the operator only needs to disassemble the housing unit. The layout of the guide channel is clearly visible, making it easy for the operator to quickly locate the problem point, greatly reducing maintenance difficulty and making the assembly and disassembly of the guide channel more convenient. At the same time, the closed housing unit wraps around the guide channel, fixing the wire conveying path and reducing wire deviation caused by vibration.

[0012] Optionally, the guide channel includes multiple guide input channels and one guide output channel. The hub housing is provided with N-level transition channels (N≥1), wherein: the output ends of at least two of the guide input channels smoothly converge into a first-level transition channel, the output ends of all the first-level transition channels smoothly converge into a second-level transition channel, and so on, the output ends of all the (N-1)th-level transition channels smoothly converge into an Nth-level transition channel, and the output end of the Nth-level transition channel is connected to the guide output channel.

[0013] By adopting the above technical solution, the hierarchical convergence of multiple inputs to a single output helps to reduce the turning angle between adjacent channels, allowing channels to converge and connect smoothly. This reduces the resistance fluctuations caused by sudden turns or abrupt changes in cross-section at the convergence point, reduces the risk of wire jamming, wire and channel wear, and ensures stability when passing through the guide output channel.

[0014] Optionally, a connecting channel is provided at the end of the guide input channel near where the wire enters, and the inner diameter of the connecting channel is larger than the inner diameter of the guide input channel.

[0015] By adopting the above technical solution, the wire feeding tube can be connected and extended into the connecting pipe, which facilitates connection and reduces the difficulty of aligning the wire entering. This is conducive to the smooth entry of the wire into the guide input channel, ensuring the continuity and smoothness of wire conveying.

[0016] This application also provides a multi-wire switcher. The technical solution adopted is as follows:

[0017] A multi-wire switcher for mounting the aforementioned multi-wire hub plate includes a mounting shell with a receiving groove inside the mounting shell. The multi-wire hub plate is disposed in the receiving groove. The mounting shell has an output mounting channel and several input mounting channels, and both the input mounting channels and the output mounting channels are connected to the receiving groove.

[0018] By adopting the above technical solution, several input installation pipes provide a standard installation position for the corresponding wire feeder in a limited space, define a safe distance for adjacent wire feeders, and avoid interference caused by equipment placement deviations.

[0019] The mounting shell forms a receiving space through a receiving groove, an input mounting channel, and an output mounting channel. It can wrap and protect the entire section of filament from the output end of the filament feeder to the output end of the mounting shell, avoiding the impact of external collisions and vibrations on the filament from the internal equipment, and improving the protection capability of the filament.

[0020] Optionally, a wire input tube is installed in the input installation channel, and a wire output tube is installed in the output installation channel. The wire input tube is connected to the wire inlet end of the multi-wire hub plate, and the wire output tube is connected to the wire outlet end of the multi-wire hub plate.

[0021] By adopting the above technical solution, the input installation channel and the output installation channel provide independent housing space for the wire input pipe and the wire output pipe, and the wire input pipe and the wire output pipe guide the wire conveying path, avoiding wear of the installation channel by the wire.

[0022] Optionally, the mounting housing has a first mounting slot and a second mounting slot, wherein an inlet sensor is installed in the first mounting slot and an outlet sensor is installed in the second mounting slot.

[0023] The input installation channel includes a first input pipe and a second input pipe. The wire input pipe includes a first input connecting pipe and a second input connecting pipe. The first input connecting pipe is located inside the first input pipe, and the second input connecting pipe is located inside the second input pipe. The first installation through groove is formed between the first input pipe and the second input pipe. The inlet sensor is located between the corresponding first input connecting pipe and the second input connecting pipe. The first input connecting pipe and the second input connecting pipe are connected to the inlet sensor, and the second input connecting pipe is connected to the guide input channel.

[0024] The output installation channel includes a first output pipe and a second output pipe. The wire output pipe includes a first output connecting pipe and a second output connecting pipe. The first output connecting pipe is located inside the first output pipe, and the second output connecting pipe is located inside the second output pipe. The second output connecting pipe is a wire outlet connector of the output installation channel. The second installation slot is opened between the first output pipe and the second output pipe. The first output connecting pipe and the second output connecting pipe are connected to the outlet sensor. The guide output channel is connected to the first output connecting pipe.

[0025] By adopting the above technical solution, the sensor determines and confirms whether the filament has been fed out and whether the return is in place. When the target filament feeder feeds filament, the filament passes through the inlet sensor, and other filaments cannot enter. The outlet sensor is used to determine whether the filament that has passed through the inlet sensor has been successfully fed out. When cutting filament, the target filament can only be fed after the filament has completely exited the outlet sensor and the inlet sensor. The two work together to ensure the orderliness of the filament feeding process and improve the reliability of multi-filament switching.

[0026] The first and second mounting slots on the mounting housing fix the positions of the inlet and outlet sensors, eliminating the need for additional mounting space, reducing the space occupied by the components, and improving the compactness of the multi-wire switch.

[0027] Optionally, the wire input tube further includes a third input connection tube, which is located inside the inlet sensor. One end of the third input connection tube is connected to the first input connection tube, and the other end of the third input connection tube is connected to the second input connection tube.

[0028] The wire output tube also includes a third output connection tube, which is located inside the outlet sensor. One end of the third output connection tube is connected to the first output connection tube, and the other end of the third output connection tube is connected to the second output tube.

[0029] Both the third input connector and the third output connector are made of non-metallic materials.

[0030] By adopting the above technical solution, the third input connecting pipe and the third output connecting pipe guide the wire and protect the sensor, reducing direct contact between the wire and the inner wall of the sensor and reducing wear on the sensor caused by the wire. The non-metallic third input connecting pipe and the third output connecting pipe enable the sensor to directly detect the metal wire, eliminate detection signal interference, ensure accurate and reliable judgment of the wire entering or leaving, and reduce wire feeding switching errors caused by signal interference.

[0031] Optionally, it also includes a mounting base, the mounting shell is mounted on the mounting base, the inlet sensor and the outlet sensor are fixedly mounted on the mounting shell, the mounting shell is also provided with a control module, and a space is left between the mounting base and the mounting shell for accommodating the inlet sensor, the outlet sensor and the control module;

[0032] The mounting housing is provided with a mounting cover, which is used to cover the mounting housing.

[0033] By adopting the above technical solution, the mounting shell serves as a unified carrier, and the internal equipment is installed in a standardized manner through channels and receiving slots. This orderly integration of components avoids the space-consuming redundancy caused by scattered component distribution, and improves the structural integration and space utilization. The mounting cover, mounting base, and mounting shell together form a fully enclosed protective space, which can isolate external dust, moisture, etc. This enhances the overall structural rigidity and ensures the overall operational stability of the multi-wire switch. It also improves the overall structural integrity, strengthens the coordination of appearance and layout, and the mounting cover makes the equipment appearance more regular, avoiding the exposure of internal components and affecting the overall aesthetics.

[0034] Optionally, the mounting base, the mounting shell, and the mounting cover are detachably connected, and all three are fan-shaped.

[0035] By adopting the above technical solution, the detachable connection design allows the three parts to be separated independently. When internal components need to be inspected, the top cover and mounting base can be quickly disassembled and installed, which facilitates quick maintenance by operators, greatly shortens the disassembly and assembly process and maintenance time, and improves maintenance efficiency. All three parts are fan-shaped and mutually compatible, reducing the overall space occupied and improving space utilization.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. The guide channels on the multi-filament hub plate provide a stable conveying path for the filaments, avoiding fluctuations in the conveying of filaments on a single pipe, reducing feeding jams caused by fluctuations, and improving the stability of filament conveying; the hub shell forms a physical barrier to prevent operators or other factors from directly contacting the channels, protecting the filaments and improving the safety of equipment operation; multiple guide channels are integrated according to a preset layout, and the hub shell serves as a unified carrier, making the filament conveying system compact and optimizing space utilization efficiency; the multi-filament hub plate can gather filaments from different positions and output them in a single direction. Its output end connects to the single-filament tool end to achieve multi-filament switching, increasing the number of filament feeders while maintaining a single output end, ensuring that the filament outlet position remains unchanged after filament switching, avoiding the tedious steps of recalibration.

[0038] 2. The detachable housing unit design allows for easy assembly by simply closing the housing unit. When the multi-wire hub plate becomes clogged or needs maintenance, operators only need to disassemble the housing unit. The layout of the guide channel is clearly visible, making it easy for operators to quickly locate the problem point and significantly reducing maintenance difficulty. The assembly and disassembly of the guide channel are also more convenient. At the same time, the closed housing unit wraps around the guide channel, fixing the wire conveying path and reducing wire deviation caused by vibration.

[0040] 4. The third input and third output connectors guide the wire and protect the sensor, reducing direct contact between the wire and the sensor's inner wall and minimizing wear. The non-metallic third input and third output connectors allow the sensor to directly detect the metal wire, eliminating interference with the detection signal and ensuring accurate and reliable judgment of wire entry or exit, thus reducing wire feeding switching errors caused by signal interference.

[0041] 5. The detachable connection design allows the mounting cover, mounting base, and mounting shell to be independently disassembled, facilitating quick disassembly and maintenance, thus improving maintenance efficiency. All three components are fan-shaped and mutually compatible, reducing overall space occupation and improving space utilization. The internal equipment is installed in a standardized manner, integrating all components in an orderly manner, avoiding the space redundancy caused by scattered components, and improving structural integration and space utilization. Together, the three components form a fully enclosed protective space, which can isolate external dust, moisture, etc. It enhances the overall structural integrity, strengthens the coordination of appearance and layout, and the mounting cover makes the equipment appearance more regular, avoiding the exposure of internal pipelines and components and affecting the overall aesthetics.

[0048] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0049] This application discloses a multi-wire hub plate.

[0050] like Figure 1 The multi-wire hub plate includes a hub shell 1, which is fan-shaped and detachable. The hub shell 1 includes two identical shell units 11, which are arranged opposite to each other and connected by bolts. A guide groove 21 is provided on the opposite side of the two shell units 11. The guide groove is opened along the wire conveying direction. When the two shell units 11 are closed, the guide grooves 21 on the two shell units 11 are precisely connected and fit together to form a guide channel 2 for the wire to pass through.

[0051] The guide channel 2 includes four guide input channels 22, one guide output channel 23 and one transition channel 24. Among the four guide input channels 22, the output ends of each two adjacent guide input channels 22 are smoothly converged into a first-level transition channel 24, and the output ends of two first-level transition channels 24 are smoothly converged into a guide output channel 23.

[0052] The input end of the guide input channel 22 is provided with a connecting channel 25. The inner diameter of the connecting channel 25 is larger than the inner diameter of the guide input channel 22, and the connecting channel 25 is smoothly connected to the guide input channel 22.

[0053] In other embodiments, the hub shell can be rectangular, elliptical or other shapes, and the hub shell 1 can also be divided into three parts, four parts or other numbers of shell units 11. For example, if four shell units 11 are used, one shell unit is used as the base and the other three shell units 11 form the top cover. The three shell units are respectively connected and fastened to the guide groove 21 on the base.

[0054] The guide channel 2 may also include six, eight, or other even-numbered guide input channels 22, or five, seven, or other odd-numbered guide input channels 22. When the total number of guide input channels 22 is even, all guide input channels 22 can converge in pairs. Two adjacent guide input channels 22 converge into a first-level transition channel 24, two adjacent first-level transition channels 24 converge into a second-level transition channel 24, two adjacent second-level transition channels 24 converge into a third-level transition channel 24, and so on. Two adjacent (N-1)th-level transition channels 24 converge into an Nth-level transition channel 24.

[0055] When the total number of guide input channels 22 is odd, the principle of pairwise aggregation is still given priority. Some guide input channels 22 are first aggregated into several upper-level transition channels 24, and the remaining guide input channel 22 is aggregated with its adjacent upper-level transition channel 24 to form a higher-level transition channel 24. Finally, the output end of the Nth-level transition channel 24 is connected to the guide output channel 23.

[0056] The first-level transition channel 24 can also be smoothly formed by three, four or other numbers of guide input channels 22, and the guide output channel 23 can also be smoothly formed by the output ends of three, four or other numbers of transition channels 24.

[0063] Four sets of input installation channels 32 are respectively equipped with wire input pipes 4 and wire output pipes 5, including a first input connecting pipe 41, a second input connecting pipe 42 and a third input connecting pipe 43. The first input connecting pipe 41 is a multi-segment connecting pipe and all of them are made of metal. The connecting pipes of the first input connecting pipe 41 near the inlet sensor 6, the second input connecting pipe 42 and the third input connecting pipe 43 are integrally formed and are made of non-metallic materials.

The other end of the third input connecting pipe 43 is connected to the second input connecting pipe 42. The other end of the second input connecting pipe 42 extends into the multi-wire hub plate and is connected to the guide input channel 22.

[0064] like Figure 2It also includes a mounting base 8, which is fan-shaped and has enclosing vertical walls around its perimeter. The height of the vertical walls is greater than the thickness of the mounting shell 3. The inlet sensor 6 and the outlet sensor 7 are fixed to the mounting shell 3 by bolts. The mounting shell 3 is also bolted to the mounting base 8. The mounting shell 3 also has a control module installed in the space between the mounting shell 3 and the mounting base 8. The mounting shell 3 has a mounting cover 9 on the side away from the mounting base 8. The mounting cover 9 is fan-shaped and fits the mounting base 8 and the mounting shell 3.
