When laser printing is required, wire is generally supplied in the direction of the fuse head, and the coaxial wire feeding fuse head coaxially sends the wire to the melting area, and finally the ring laser passes through the focusing lens and focuses on the wire position; the wire is in the middle and the ring laser surrounds the wire in an additive manner. The laser is annular, the energy distribution is uniform all around, the additive is non-directional, and the forming is more uniform; however, in the prior art, in the additive process, the cladding layer of the additive is uneven when viewed from the side, the interface between the layers is obvious, and the side wall and the additive are not on the same plane.

[0047] Example 1: Figure 1-Figure 2 As shown, a device for synchronous shaping of a coaxial fuse additive process can remelt the side wall of the additive part while the fuse is being added, thereby improving the forming accuracy and flatness of the side wall. The device includes:

[0048] Related equipment for performing coaxial fused wire additive: Reference Figure 1 and Figure 3As shown, laser 1 is used to emit laser 2; laser 2 is focused on annular nozzle 3 through a focusing lens after passing through a reflector and a collimator; a wire feeding structure is provided at the annular nozzle 3 for feeding wire 4 from the axial direction of the annular nozzle 3; laser 2 is focused on the position of wire 4 in the annular nozzle 3; an additive method is formed in which wire 4 is in the middle and annular laser 2 surrounds wire 4; laser 2 is annular, energy distribution is uniform all around, additive is non-directional, and forming is more uniform; additive operation is performed as the device moves or the bottom tray moves, wherein data and positions of reflectors, collimators and focusing lenses are adjusted as needed to achieve the above functions; this process is the same as the principle of a conventional coaxial fuse device.

[0049] Related devices for performing synchronous shaping: Based on the above structure, it is also provided with:

[0050] The first light splitting mechanism guides the laser 2 to be completely reflected to the annular nozzle 3, or divides the laser 2 into laserone 7 and lasertwo 8 as needed; laserone 7 is reflected to the annular nozzle 3, and lasertwo 8 enters the multi-faceted reflection mechanism; the multi-faceted reflection mechanism is configured to guide lasertwo 8 to continuously transmit on several non-parallel surfaces; and each surface is provided with a shaping mechanism, the shaping mechanism includes an intercepting reflector 11, a light guide channel 13 and a rectangular shaping nozzle, and the rectangular shaping nozzle is arranged parallel to the corresponding surface; the shaping mechanism is configured to perform the following actions:

[0051] Controlling the intercepting reflector 11 of one of the shaping mechanisms to move, intercepting lasertwo8, and reflecting lasertwo8 toward the corresponding light guide channel 13;

[0052] The light guide channel 13 guides the laser two 8 to be transmitted to the corresponding rectangular shaping nozzle.

[0053] Specific: Reference Figure 4 As shown, the laser is bolded to facilitate better understanding of the splitting. The first splitting mechanism includes a beam splitter 5 and a sliding adjustment assembly 6. The beam splitter 5 is assembled on the sliding adjustment assembly 6. The sliding adjustment assembly 6 is configured to drive the beam splitter 5 to move linearly, control the laser to be fully reflected to the annular nozzle 3 or split the laser into laserone 7 and lasertwo 8.

[0054] Among them, the sliding adjustment component 6 is used to realize the linear movement of the spectroscope 5; for example, a lead screw and a lead screw nut are used in combination, the lead screw is equipped with a coupling and a drive motor for driving, the lead screw nut is connected to the base of the spectroscope 5 through a connecting block, and the lead screw nut is driven by the lead screw to move, so that the spectroscope 5 moves linearly. A track can be provided at the connecting block or the base of the spectroscope 5 to guide the stable movement of the spectroscope 5.

[0055] refer to Figure 5 As shown, the multi-faceted reflection mechanism includes a main reflector 9 and several branch reflectors 10. Each branch reflector 10 is installed at the connection of adjacent surfaces. The main reflector 9 is used to reflect lasertwo8 to any branch reflector 10. The branch reflectors 10 are combined to guide lasertwo8 to transmit between the surfaces.

[0056] Taking the additive part as a quadrilateral as an example, the multi-faceted reflection mechanism includes a main reflector 9 and three branch reflectors 10. The three branch reflectors 10 are respectively installed at the corners of each adjacent surface. The lasertwo8 is reflected by the main reflector 9 to one of the branch reflectors 10, and then reflected by the branch reflector 10 to the next branch reflector 10, until it is reflected to the last branch reflector 10.

[0057] For plastic surgery institutions, including:

[0058] Interceptor 11, reference Figure 6 As shown, a frame 12 is provided at the bottom of the intercepting reflector 11, and the frame 12 is connected to a power source. The function of the power source is to push the frame 12 to move. When the frame 12 is on the transmission path of lasertwo8, the laser passes through the hole in the frame 12 and continues to be transmitted along the original path. When the intercepting reflector 11 is on the transmission path of lasertwo8, the lasertwo8 is reflected toward the direction of the light guide channel 13 by setting the angle of the intercepting reflector 11 on the transmission path of lasertwo8.

[0059] Light guide channel 13, reference Figure 7 As shown, a number of reflectors, collimators and focusing mirrors are arranged inside, and each lens is arranged as needed, and the laser is guided to the rectangular shaping nozzle through the action of each lens;

[0060] The rectangular shaping nozzle is arranged at the side wall of the additive part and is located below the annular nozzle 3. After the annular nozzle 3 performs additive work, the laser is guided through the rectangular shaping nozzle to scan the side after the additive work, remelting the side once to improve the flatness of the side.

[0061] The control of the rectangular shaping nozzle is configured so that when the additive surface is switched for additive and shaping, the rectangular shaping nozzle of the previous surface is reset to a waiting position that does not affect the movement of the device, and the rectangular shaping nozzle corresponding to the next surface is moved to the working position for synchronous shaping operations.

[0062] For further reference, Figure 1-Figure 2 As shown, a lifting structure 15 is installed on one side of the light guide channel 13, and the lifting structure 15 is used to control the movement of the light guide channel 13 and drive the rectangular shaping nozzle to be in the working position or the waiting position; and the lifting structure 15 is connected to the frame 12 as a power source, and synchronously drives the frame 12 to move:

[0063] Among them, reference Figure 1 As shown, a telescopic straight-cylinder structure 17 is provided in the middle of the light-guiding channel 13, including an inner and outer sleeve, which does not affect the linear transmission of the laser when it is telescoped. The lifting structure 15 is connected to the telescopic straight-cylinder structure 17, controls the telescopic straight-cylinder structure 17 to perform telescopic operation, and synchronously drives the rectangular shaping nozzle to be in the working position or the waiting position;

[0064] For the lifting structure 15, to realize the movement of the light guide channel 13, such as a hydraulic telescopic cylinder, the telescopic end is connected to the retractable straight tube structure through a connecting rod 16 and other structures, and is connected to the frame 12;

[0065] That is, Figure 2 For example, the lifting structure 15 is extended and retracted in the vertical direction. When the annular nozzle 3 is at the left side of the additive part for additive operation, the lifting structure 15 on the left side works to move the telescopic straight cylinder on the left side downward, thereby moving the rectangular shaping nozzle on the left side downward to the working position. At the same time, the frame 12 and the intercepting reflector 11 on the left side are driven to move downward synchronously. At this time, the intercepting reflector 11 is on the transmission path of lasertwo8. The intercepting reflector 11 is intercepted and guided by the intercepting reflector 11 to be transmitted into the light guide channel 13, and then transmitted along the light guide channel 13 to the rectangular shaping nozzle at the working position below, and the remelting and shaping operation is performed simultaneously with the above additive operation.

[0066] The annular nozzles 3 on the other surfaces are all in the waiting position and the control frame 12 is on the transmission path of the laser two 8 .

[0067] Furthermore, in the above structure, a laser scanning mechanism is provided on one side of the rectangular shaping nozzle along the direction of the additive operation of the annular nozzle 3. The laser scanning mechanism is used to emit a line laser to scan the side wall of the additive part. The laser scanning mechanism obtains the contour of the side wall through sensor analysis and sends the contour information to the computer. The computer makes the following instructions:

[0068] When the surface profile fluctuation is greater than a preset value A, the first light splitting mechanism splits the laser into laserone7 and lasertwo8;

[0069] The lifting structure 15 of the corresponding surface of the additive part works, controlling the corresponding intercepting reflector 11 to be on the transmission path of the lasertwo8, and the rectangular shaping nozzle is in the working position;

[0070] The lasertwo8 is transmitted to the rectangular shaping nozzle for injection, and the areas with large contour fluctuations are remelted.

[0071] Furthermore, laser scanning mechanisms are arranged on both sides of the rectangular shaping nozzle along the additive operation direction of the annular nozzle 3; the rectangular shaping nozzle includes two, the two rectangular shaping nozzles are arranged front and back along the additive growth direction, and a second light splitting mechanism is arranged between the two rectangular shaping nozzles. The second light splitting mechanism has the same structure as the first light splitting mechanism, and the following operations are performed by the second light splitting mechanism:

[0072] When the first laser scanning mechanism 181 recognizes that the surface profile fluctuation at the next moment is not greater than the preset value A, the second light splitting mechanism reflects and transmits lasertwo8 to the second rectangular shaping nozzle;

[0073] When the first laser scanning mechanism 181 recognizes that the surface profile fluctuation at the next moment is greater than the preset value A, the second light splitting mechanism splits lasertwo8 into lasertwo8_1 and lasertwo8_2, and transmits them to the two rectangular shaping nozzles respectively.

[0074] Embodiment 2: A method for synchronous shaping of a coaxial fuse during an additive process, using the device for synchronous shaping of a coaxial fuse during an additive process according to any one of claims 6 to 9, comprising the following steps:

[0075] The laser light emitted by the laser 1 is reflected to the annular nozzle 3 by the first beam splitting mechanism, and is focused on the position of the wire 4 in the annular nozzle 3; an additive operation is performed in which the wire 4 is in the middle and the annular laser surrounds the wire 4;

[0076] During the additive process, the side wall of the additive part is identified by the laser scanning mechanism, and when the surface profile fluctuation is greater than the preset value A, the first light splitting mechanism is controlled to perform light splitting operation to split the laser into laserone7 and lasertwo8; lasertwo8 is transmitted to the multi-faceted reflection mechanism;

[0077] And perform the following operations based on different situations:

[0078] First, the opposite rectangular shaping nozzle is controlled to be in the working position by the lifting structure 15; the corresponding intercepting reflector 11 is on the transmission path of lasertwo8, intercepting and reflecting the lasertwo8 to the corresponding rectangular shaping nozzle; the rectangular shaping nozzle is used to integrate the laser beam into a rectangle, and the laser beam is swept from the side of the additive part to remelt the area with large contour fluctuation;

[0079] The laser scanning mechanism on the other side, i.e., the second laser scanning mechanism 182, identifies the side wall of the additive part after remelting, and marks it when the surface profile fluctuation is still greater than the preset value A. As the additive grows, the entire device moves upward relative to the additive part. At this time, the rectangular shaping nozzle below, i.e., the second rectangular shaping nozzle 142, is at a position where the surface profile fluctuation is still greater than the preset value A after the last remelting. At this time:

[0080] When the laser scanning mechanism on the upper rectangular shaping nozzle, i.e. the first rectangular shaping nozzle 141, i.e. the first laser scanning mechanism 181, recognizes the side wall of the additive part, when:

[0081] When the surface profile fluctuation is greater than the preset value A, the second light splitting mechanism splits lasertwo8 into lasertwo_1 and lasertwo_2, and transmits them to two rectangular shaping nozzles respectively. The first rectangular shaping nozzle 141 is used for synchronous remelting, and the second rectangular shaping nozzle 142 is used for secondary remelting.

[0082] When the surface profile fluctuation is no greater than the preset value A, the second splitter mechanism reflects lasertwo8 and transmits it to the second rectangular shaping nozzle. The second rectangular shaping nozzle 142 is used for secondary remelting. In all the above operations, the total energy of the laser output by the laser 1 changes accordingly to ensure the needs of each operation.
