Description

Technical Field

[0001] This application relates to a 3D printed artificial bait and a method for preparing the artificial bait. Background Technology

[0002] Artificial lures are mimicking small fish, using swimming action and other techniques to attract the interest of larger fish or other predators. The components of an artificial lure generally include an outer shell, to which a hook is attached for fishing, and internal weights to maintain or control the swimming action. Since most artificial lures are now assembled, their weights are usually integrated into the lure itself. However, for 3D-printed lures, because they are molded as a single piece, there is no basis for internal weight assembly, requiring a redesign and repositioning of the weight structure. Summary of the Invention

[0003] To address the aforementioned issues, this application proposes a 3D-printed artificial lure, comprising a one-piece shell. A force-applying ring, integrally formed with the shell, is located at the rear of the shell. Several hook swivels, also integrally formed with the shell, are located on other parts of the shell. A tail weight, integrally formed with the shell, is located on the inner side of the shell corresponding to the force-applying ring. The force-applying ring and tail weight, working together, create a stable point of force application, providing a structural foundation for the lure's stable movement in water. The auxiliary weights at the front or middle can be configured differently depending on the lure's movement requirements.

[0004] Preferably, an auxiliary counterweight is provided at the lower end of the integrated housing away from the tail counterweight and / or at the lower center of the integrated housing;

[0005] The tail counterweight and the auxiliary counterweight each include a protrusion located in the middle, and the protrusion is integrally formed with the inner side of the one-piece shell;

[0006] The protrusion includes a counterweight body located in the middle, and an outer annular plate is provided on the outside of the counterweight body. The thickness of the outer annular plate gradually decreases in the direction away from the counterweight body, and the outer annular plate is fixedly connected to the integral shell.

[0007] A reinforcing connecting plate is provided between the protrusion and the integral housing, and the thickness of the reinforcing connecting plate gradually decreases in the direction away from the protrusion.

[0008] The cross-section of the reinforcing connecting plate has an inner radius (R) shape.

[0009] Preferably, the auxiliary counterweight is a front counterweight located at the front and a middle counterweight located in the middle, or the auxiliary counterweight is a middle counterweight located in the middle.

[0010] Preferably, reinforcing outer strips are provided between the force-applying pull ring and the integrated housing and between the hook hanging ring and the integrated housing, and the thickness of the reinforcing outer strips gradually decreases in the direction away from the protrusion;

[0011] The cross-section of the reinforcing outer strip is an inner R-angle shape. This application achieves a better edge transition by providing an outer annular plate on the outside of the protrusion and supplementing it with a reinforcing connecting plate. On the other hand, the force-applying pull ring / fishhook hook ring and the outer part of the integrated shell are provided with a reinforcing outer strip to further ensure the connection strength of the edge transition.

[0012] Preferably, the integral shell portion located at the force-applying pull ring and the lower portion is made of TC4 titanium alloy plate with a thickness of 1-1.3 mm; the integral shell portion in other parts is made of TC4 titanium alloy plate with a thickness of 0.8-1 mm. This application uses TC4 titanium alloy plates of different thicknesses, resulting in better tensile strength. Furthermore, due to its 3D-printed integrated design, it can easily achieve structural designs of varying thicknesses.

[0013] Preferably, the integrated housing is provided with several through holes for discharging internal powder; sealing nuts or welded material are provided on the through holes;

[0014] There are two through holes, which are located on the tail counterweight and / or auxiliary counterweight.

[0015] On the other hand, this application also discloses a method for preparing artificial bait, including the following steps:

[0016] The structure of the lure is decomposed along its height direction to obtain the decomposed structure along the height direction;

[0017] Based on the decomposed structure, titanium alloy is used as the raw material for 3D printing in the following manner:

[0018] A layer of titanium alloy powder is pushed onto the printing area according to the height requirements of the decomposed structure, and the printing area is fused and printed using a 3D printing laser head.

[0019] After printing is complete, another layer of titanium alloy powder is pushed according to the height requirements of the decomposed structure, and then the 3D printing laser head is used to fuse and print the printed part.

[0020] Continue repeating the pushing, fusion, and printing steps until the entire dummy is complete;

[0021] The titanium alloy powder inside the integrated shell is extracted through a pre-drilled or drilled through-hole, and then the through-hole is sealed. This application uses a powder-pushing method, with the titanium alloy powder as a carrier. The 3D printing laser head melts the titanium alloy powder, ensuring accurate positioning and avoiding deviation in the printing position. This allows for successful fusion of the titanium alloy powder, ultimately resulting in a 3D-printed dummy.

[0022] Preferably, the height of the decomposed structure is 0.03-0.06 mm.

[0023] Preferably, when the height of the exploded structure is 0.03 mm, the 3D printing laser head printing parameters are as follows:

[0024] Scanning interval: 0.1000mm for the upper surface and 0.0500mm for the lower surface;

[0025] Scanning speed: 700 mm / s for the upper surface, 2200 mm / s for the lower surface;

[0026] Laser power: 150.0kW for both the upper and lower surfaces;

[0027] When the height of the exploded structure is 0.04 mm, the printing parameters of the 3D printing laser head are as follows:

[0028] Scanning interval: 0.1000mm for the upper surface and 0.0500mm for the lower surface;

[0029] Scanning speed: 650.000 mm / s for the upper surface and 2200 mm / s for the lower surface;

[0030] Laser power: 160kW for the upper surface and 180kW for the lower surface;

[0031] When the height of the exploded structure is 0.06 mm, the printing parameters of the 3D printing laser head are as follows:

[0032] Scanning interval: 0.0900mm for the upper surface and 0.0500mm for the lower surface;

[0033] Scanning speed: 800 mm / s for the upper surface, 2000 mm / s for the lower surface;

[0034] Laser power: 250kW for the upper surface and 240kW for the lower surface.

[0035] Preferably, the height direction is a direction that extends from the highest or lowest point of the applied pull ring to the other end along the direction of the fish body.

[0036] This application can bring the following beneficial effects:

[0037] 1. The force-applying pull ring and the tail counterweight of this application are designed to make this a stable force-applying point, thereby providing a structural basis for the stable movement of the lure in the water. The auxiliary counterweights at the front or middle can be set in different ways according to the requirements of the lure's movement posture.

[0038] 2. This application achieves a better edge transition by providing an outer annular plate on the outer side of the protrusion and supplementing it with a reinforcing connecting plate. On the other hand, the force-applying pull ring / fishhook hanging ring and the outer side of the integrated shell are provided with reinforcing external strips to further ensure the connection strength of the edge transition.

[0039] 3. This application adopts a powder pushing method, and then uses titanium alloy powder as a carrier to melt the titanium alloy powder using a 3D printing laser head. This can ensure the accuracy of positioning and avoid the deflection of the printing position, so as to successfully complete the melting of titanium alloy powder and finally obtain a 3D printed dummy.

[0040] The accompanying drawings, which are included to provide a further understanding of this application and form part of this application, illustrate exemplary embodiments and are used to explain this application, but do not constitute an undue limitation of this application. In the drawings:

[0041] Figure 1 This is a schematic diagram of the structure of this application;

[0042] Figure 2 for Figure 1 Enlarged schematic diagram of part A;

[0043] Figure 3 This is a schematic diagram of the external structure of this application. Detailed Implementation

[0044] To clearly illustrate the technical features of this solution, the following detailed description, in conjunction with the accompanying drawings, will be provided.

[0045] Regarding the mechanical structure of the lure itself, such as Figure 1-3 As shown, a 3D-printed artificial lure includes a one-piece shell 1. A pull ring 2, integrally formed with the shell 1, is located at the rear of the shell 1. Several hook swivels 3, also integrally formed with the shell 1, are located on other parts of the shell 1. A tail weight 4, integrally formed with the shell 1, is located on the inner side of the shell 1 corresponding to the pull ring 2. This application uses the tail weight 4 as a base point and the pull ring 2 as the point of force application, thereby enabling relatively stable control of the lure's swimming action through the tail weight 4, avoiding problems with unstable swimming action.

[0046] An auxiliary counterweight 5 is provided at one end of the integrated housing 1 away from the tail counterweight 4 and / or at the middle of the bottom of the integrated housing 1.

[0047] The tail counterweight 4 and the auxiliary counterweight 5 each include a protrusion located in the middle, and the protrusion is integrally formed with the inner side of the one-piece shell.

[0048] The protrusion includes a counterweight body 6 located in the middle, and an outer annular plate 7 is provided on the outside of the counterweight body 6. The thickness of the outer annular plate 7 gradually decreases in the direction away from the counterweight body 6, and the outer annular plate 7 is fixedly connected to the integral shell.

[0049] A reinforcing connecting plate 8 is provided between the protrusion and the integral housing 1, and the thickness of the reinforcing connecting plate 8 gradually decreases in the direction away from the protrusion.

[0050] The cross-section of the reinforcing connecting plate 8 has an inner R-angle shape.

[0051] The auxiliary counterweight 5 is either a front counterweight 51 located at the front or a middle counterweight 52 located in the middle, or the auxiliary counterweight 5 is a middle counterweight 52 located in the middle.

[0052] A reinforcing outer strip 9 is provided between the force-applying pull ring 2 and the integrated housing 1 and between the fishing hook hanging ring 3 and the integrated housing 1, respectively. The thickness of the reinforcing outer strip 9 gradually decreases in the direction away from the protrusion.

[0053] The cross-section of the reinforcing outer strip 9 has an inner R-angle shape.

[0054] The integral housing 1 is made of TC4 titanium alloy plate with a thickness of 1-1.3mm in the part of the force-applying ring 2 and the lower part; the integral housing 1 in other parts is made of TC4 titanium alloy plate with a thickness of 0.8-1mm.

[0055] The integrated housing 1 is provided with several outlet through holes 8 for discharging internal powder; sealing nuts or welding stacks are provided on the outlet through holes 8;

[0056] There are two through holes 8, which are located on the tail counterweight 4 and / or auxiliary counterweight 5. Because this application uses a powder-pushing and fusion method, the interior of the one-piece shell 1 is filled with raw material powder. This application uses a post-processing method to remove the internal powder, ensuring the quality of the one-piece shell 1. The opening can be designed and left during 3D printing or can be drilled. The through holes 8 are located on the thickened tail counterweight 4 or auxiliary counterweight 5 to prevent deformation of the through holes 8 during material handling and printing, which would affect the overall shape stability of the dummy.

[0057] On the other hand, the specific preparation method for artificial bait includes the following steps:

[0058] The structure of the lure is decomposed along its height direction to obtain a decomposed structure along the height direction (the height direction is the direction that extends from the highest or lowest point of the pull ring 2 towards the other end along the direction of the fish body); the height of the decomposed structure is 0.03-0.06mm.

[0059] Based on the decomposed structure, titanium alloy is used as the raw material for 3D printing in the following manner:

[0060] A layer of titanium alloy powder is pushed onto the printing area according to the height requirements of the decomposed structure, and the printing area is fused and printed using a 3D printing laser head.

[0061] After printing is complete, another layer of titanium alloy powder is pushed according to the height requirements of the decomposed structure, and then the 3D printing laser head is used to fuse and print the printed part.

[0062] Continue repeating the pushing, fusion, and printing steps until the entire dummy is complete;

[0063] The titanium alloy powder inside the integral housing 1 is extracted through a pre-drilled or drilled through-hole, and then the through-hole is sealed. If a pre-drilled through-hole is used, it needs to be considered when disassembling the structure.

[0064] Example 1:

[0065] Following the above process, TC4 titanium alloy powder was used as the raw material. Two through holes were pre-drilled, and the holes were sealed by welding.

[0068] Scanning speed: 700 mm / s for the upper surface, 2200 mm / s for the lower surface;

The thickness of the integral shell located in the force-applying ring 2 section and the lower part was set to 1.2mm; the thickness of the integral shell in other parts was set to 0.9mm.

[0073] Following the above process, TC4 titanium alloy powder is used as the raw material:

[0074] The height of the exploded structure is 0.04 mm, and the printing parameters of the 3D printing laser head are as follows;

[0075] Scanning interval: 0.1000mm for the upper surface and 0.0500mm for the lower surface;

[0076] Scanning speed: 650.000 mm / s for the upper surface and 2200 mm / s for the lower surface;

[0077] Laser power: 160kW for the upper surface and 180kW for the lower surface;

[0078] Finally, we got lure number 2.

[0079] Example 3:

[0080] Following the above process, TC4 titanium alloy powder was used as the raw material. Two through holes were pre-drilled, and the holes were sealed by welding. The thickness of the integral shell located in the force-applying ring 2 section and the lower part was set to 1.3mm; the thickness of the integral shell in other parts was set to 1mm.

[0081] Following the above process, TC4 titanium alloy powder is used as the raw material:

[0082] The height of the exploded structure is 0.06mm, and the 3D printing laser head printing parameters are as follows;

[0083] Scanning interval: 0.0900mm for the upper surface and 0.0500mm for the lower surface;

[0085] Laser power: 250kW for the upper surface and 240kW for the lower surface.

[0086] Finally, we got lure number 3.

[0087] Comparative Example 1:

[0088] Based on Example 1, the thickness of the integral shell located in the force-applying ring 2 part and the lower part is set to 1mm; the thickness of the integral shell part in other parts is set to 1mm, and finally the No. 4 artificial lure is obtained.

[0089] Then connect lure #1 and lure #4 using a connecting ring, apply force from both sides until one of the lures breaks. In the end, lure #4 is stretched and damaged.
