[0002] Forging is one of the commonly used technologies in the production of mechanical products. The mold used in forging is the key to product forming. Due to the repeated strong forging of the mold during forging, after a certain period of time, the mold cavity will expand in geometric dimensions to varying degrees, and even cracks will appear in some parts. It is necessary to use forging mold 3D printing additive welding equipment to repair it.

[0003] Meanwhile, the publicly disclosed (announcement) number CN215356188U is an automatic wire changing device for additive welding in forging die 3D printing. The automatic wire changing device for additive welding in forging die 3D printing includes a working arm; a fixing component; a welding gun component; and a driving component. Through the coordinated use of the driving component, auxiliary component, and correction component, the replacement of welding wire in the welding gun can be faster and save manpower.

[0004] The aforementioned automatic wire changing device for additive welding in 3D printing of forging dies only has one drive component installed during use to assist and correct the welding wire. It still requires the operator to change the welding gun component after a batch of welding wire is used up, which cannot effectively reduce the wire changing time and leads to a decrease in production efficiency.

[0005] Therefore, an automatic wire changing device for additive welding of forging die 3D printing is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an automatic wire changing device for additive welding in forging die 3D printing. This device reduces downtime caused by wire changing, improves machine efficiency, and cleans the welding wire to prevent other impurities from damaging the machine.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic wire changing device for additive welding of forging die 3D printing, comprising a printer, a drive assembly on the top of the printer, and a wire changing assembly on the top of the drive assembly;

[0008] The wire changing assembly includes a material box, a circular cavity inside the material box, a consumable fixing column fixedly installed inside the circular cavity, a support block fixedly installed at the bottom of the material box, and a wire feeding assembly fixedly installed inside the cavity of the wire changing assembly.

[0009] The wire feeding assembly includes a wire wheel driver, a wire wheel is fixedly mounted on the right side of the wire wheel driver, a lower clamp is fixedly mounted on the rear right side of the wire wheel driver, a telescopic spring is fixedly mounted on the top of the lower clamp, an upper clamp is sleeved on the top of the telescopic spring, and a guide post is fixedly mounted on the front right side of the wire wheel driver.

[0010] Preferably, a correction opening is fixedly provided on the outer periphery of the material box, and the correction opening penetrates through the shell surface of the material box.

[0011] By adopting the above technical solution, the fed welding wire is aligned with the wire feeder.

[0012] Preferably, the drive assembly includes a drive motor, a motor base is fixedly provided at the bottom of the drive motor, a worm is provided at the end of the main shaft of the drive motor, and a worm wheel is engaged at the rear end of the worm.

[0013] By adopting the above technical solution, the rotation of the material box in the plane can be controlled.

[0014] Preferably, a support frame is fixedly provided on the left side of the motor base, and a wire feeder is fixedly provided on the right end of the support frame.

[0015] By adopting the above technical solution, the wire feeder can be fixed in a suitable position for operation.

[0016] Preferably, the printer and the drive assembly are rotatably connected via a fixed shaft, and the drive assembly and the filament changing assembly are fixedly connected via a support block.

[0017] By adopting the above technical solution, the printer will not be driven to rotate when the drive component rotates the material box.

[0018] Preferably, the upper clamp is slidably connected to the telescopic spring, and sponge blocks are installed on the top of the lower clamp and the bottom of the upper clamp.

[0019] By adopting the above technical solution, the direction of the welding wire can be fixed before it is fed into the wire wheel, and the welding wire can be cleaned.

[0020] Preferably, there are three wire feeding assemblies and consumable fixing posts, and the wire feeding assemblies and consumable fixing posts are arranged in a circular distribution within the circular cavity of the wire changing assembly.

[0021] By adopting the above technical solutions, the service life of additive welding equipment can be extended and the number of wire replacements can be reduced.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. This utility model uses a clamping structure in the wire feeding assembly. The upper and lower clamps connected by a telescopic spring draw the welding wire from the material tray and place it into the clamp. Under the action of the sponge block, the welding wire will not be clamped, which would prevent the wire wheel from drawing out the welding wire. The sponge block can also be used to clean the welding wire, ensuring that no other impurities remain on the surface of the welding wire, which could damage the wire feeder.

[0024] 2. This utility model uses a wire changing assembly in conjunction with a drive assembly. After the first coil of welding wire is used up, the motor drives the material box to rotate the next batch of welding wire installed in the box to the feed port of the wire feeder. The wire feeding assembly continues to work, reducing the downtime caused by wire changing and improving the working efficiency of the machine. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] The following describes an embodiment of this utility model based on its overall structure.

[0035] like Figures 1 to 4 As shown, this utility model provides an automatic wire changing device for additive welding of forging die 3D printing, including a printer 1, a drive assembly 2 on the top of the printer 1, and a wire changing assembly 3 on the top of the drive assembly 2.

[0036] The wire changing assembly 3 includes a material box 31 with a circular cavity inside. A consumable fixing post 34 is fixedly installed inside the circular cavity. The welding wire spool is inserted into the consumable fixing post 34 and fixedly installed inside the material box 31. A support block 32 is fixedly installed at the bottom of the material box 31 to fix the material box 31 to the worm gear. A wire feeding assembly 4 is fixedly installed inside the cavity of the wire changing assembly 3.

[0037] A straightening port 33 is fixedly provided around the outer side of the material box 31, and the straightening port 33 penetrates through the shell surface of the material box 31. The welding wire is extracted by the wire feeding assembly 4 and fed into the wire feeder 5 for processing.

[0038] The wire feeding assembly 4 includes a wire wheel driver 41, a wire wheel 42 is fixedly mounted on the right side of the wire wheel driver 41, a lower clamp 43 is fixedly mounted on the rear right side of the wire wheel driver 41, a telescopic spring 45 is fixedly mounted on the top of the lower clamp 43, an upper clamp 44 is sleeved on the top of the telescopic spring 45, and a guide post 46 is fixedly mounted on the front right side of the wire wheel driver 41 so that the welding wire will not deviate from the direction of entering the straightening port 33 after being pulled out by the wire wheel 42.

[0039] In this embodiment, the drive assembly 2 includes a drive motor 21, a motor base 24 is fixedly provided at the bottom of the drive motor 21, a worm 22 is provided at the end of the main shaft of the drive motor 21, and a worm wheel 23 is engaged at the rear end of the worm 22. The worm 22 is driven to rotate by the drive motor 21, and at the same time, it drives the worm wheel 23 to rotate in the plane.

[0040] A support frame 12 is fixedly installed on the left side of the motor base 24, and a wire feeder 5 is fixedly installed on the right end of the support frame 12.

[0041] The printer 1 and the drive assembly 2 are rotatably connected via a fixed shaft 11. The drive assembly 2 and the filament changing assembly 3 are fixedly connected via a support block 32. When the worm gear 32 in the drive assembly 2 rotates, the filament changing assembly can be driven to rotate simultaneously via the support block 32.

[0042] The upper clamp 44 is slidably connected to the telescopic spring 45. Pulling the upper clamp allows the welding wire to be inserted. Sponge blocks are installed on the top of the lower clamp 43 and the bottom of the upper clamp 44 to clean the welding wire.

[0043] There are three wire feeding components 4 and consumable fixing posts 34. The wire feeding components 4 and consumable fixing posts 34 are arranged in a circular distribution within the circular cavity of the wire changing component 3. The drive component 2 rotates the wire changing component 3 to the next material tray and then starts working.

[0044] The motor is existing technology and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is already known technology. The appropriate model should be selected according to actual use. Therefore, the control method and wiring layout of the motor will not be explained in detail.

[0045] Working principle and process of an automatic wire changing device for additive welding in 3D printing of forging dies:

[0046] When workers need to use the additive welding device, they place the three wire spools into the material box 31 along the support block 32, pull out one end of the wire, lift the upper clamp 44 with the extension spring 45, put in the wire, and release the upper clamp 44 to return it to the lower clamp 43. At this time, the wire is fixed by the sponge block and can continue to be pulled out to feed the wire into the wire wheel 42 for fixing. The other two wire spools are fixed in the same way. Then the additive welding device is started. The wire wheel drive motor 41 in the direction of the wire feeder 5 is started. The wire wheel 42 pulls the wire out of the material box 31. The wire is fed into the straightening port 33 through the guide post 46 and finally fed into the wire feeder 5 for welding.

[0047] When the first spool of welding wire is used up, the drive motor 21 starts, driving the worm gear 22 and the worm wheel 23 to rotate. The support block 32, which is fixedly installed on the top of the worm wheel 23, rotates, causing the material box to rotate. The next straightening port 33 rotates to the direction of the wire feeder 5. After the straightening port 33 is aligned with the wire feeder 5, it stops. Since the second spool of welding wire has been fixed, it automatically starts to pass through the wire feeding assembly 4 to begin the above-mentioned workflow.
