Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of finesing agent addition devices, specifically to a finesing agent addition device for welding additive manufacturing. Background Technology
[0002] Additive manufacturing technology is a technique for manufacturing solid parts by gradually adding materials. Compared with traditional material removal-cutting technology, it is a "bottom-up" manufacturing method. By adding a refining agent during the welding additive deposition process, it is possible to effectively ensure that the grain size of the formed sample is significantly refined and the porosity is reduced, thereby reducing stress concentration and improving mechanical properties and internal quality.
[0003] However, many existing fine-refining agent addition devices, when in use, not only affect the effect of the fine-refining agent because the fine-refining agent is in powder form, but also cause it to clump together when it gets damp, making it difficult to transfer out of the device.
[0004] In view of this, the present invention proposes a welding additive manufacturing finesing agent addition device. Utility Model Content
[0005] This utility model proposes a welding additive manufacturing refiner addition device, which solves the problem that many existing refiner addition devices in related technologies have the problem that when the refiner is in powder form, it will not only affect the use effect when it gets damp, but also cause it to clump together and be difficult to transfer out of the equipment.
[0006] The technical solution of this utility model is as follows: A welding additive manufacturing finesing agent addition device includes a storage tank, an outlet threadedly connected to the surface of the storage tank, a conduit fixedly connected to the bottom of the outlet, a connecting ring threadedly connected to the inner wall of the storage tank, a top cover fixedly connected to the top of the connecting ring, a motor fixedly connected to the top of the top cover, a stirring rod fixedly connected to the output end of the motor, an installation ring fitted to the inner wall of the storage tank, a heating wire fixedly connected inside the installation ring, a retaining ring fitted to the top of the installation ring, and a through hole provided on the surface of the storage tank, through which a screw threadedly connected to the inside of the retaining ring passes.
[0007] Preferably, the surface of the storage tank is threaded with a control ring, the bottom of the control ring is slidably connected with a connecting rod, the bottom of the connecting rod is fixedly connected with a slide rod that is slidably connected to a conduit, and the surface of the conduit is fixedly connected with a limit ring.
[0008] Preferably, the outlet and the storage tank are detachable, and the outlet has a conical structure.
[0009] Preferably, the mounting ring is made of stainless steel, and several sets of heating wires are vertically arranged inside the mounting ring.
[0010] Preferably, the mounting ring fits tightly against the storage tank, and the retaining ring completely seals the top of the mounting ring.
[0011] Preferably, the stirring rod is rotated inside the storage tank by a motor, and the stirring rod does not contact the inner wall of the storage tank.
[0012] Preferably, the conduit is a flexible hose, and the connecting rod forms a lifting structure through a control ring.
[0013] Preferably, the limiting ring is located on the movement trajectory of the slide rod.
[0014] The working principle and beneficial effects of this utility model are as follows:
[0015] 1. In this utility model, by setting a control ring, when it is necessary to add a finer agent, the control ring can be rotated to make it move downward along the storage tank, thereby driving the connecting rod that is embedded and slidably connected to itself to descend. When the connecting rod descends, it will push the conduit downward through the slide rod, making the conduit tilt downward. At this time, the finer agent will flow out from the inside of the conduit, achieving the purpose of adding. When it is not necessary to add, the control ring can be rotated to make the conduit face upward.
[0016] 2. In this utility model, a heating wire is installed to prevent the refining agent from getting damp. The heat dissipated by the heating wire heats the storage tank. Then, the motor is turned on to control the stirring rod to rotate slowly, thereby stirring the refining agent and performing periodic drying treatment. When the heating wire needs to be inspected, the screws can be removed and the retaining ring can be taken out. The installation ring can then be taken out from inside the storage tank to achieve the purpose of disassembling the heating wire. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0025] Example 1
[0026] A preferred embodiment of the welding additive manufacturing refining agent addition device provided by this utility model is, for example... Figures 1 to 5 As shown: A welding additive manufacturing finesing agent addition device includes a storage tank 1, an outlet 2 threadedly connected to the surface of the storage tank 1, a conduit 3 fixedly connected to the bottom of the outlet 2, a connecting ring 4 threadedly connected to the inner wall of the storage tank 1, a top cover 5 fixedly connected to the top of the connecting ring 4, a motor 6 fixedly connected to the top of the top cover 5, a stirring rod 7 fixedly connected to the output end of the motor 6, an installation ring 8 attached to the inner wall of the storage tank 1, a heating wire 9 fixedly connected inside the installation ring 8, a retaining ring 10 attached to the top of the installation ring 8, and a through hole 11 provided on the surface of the storage tank 1, through which a screw 12 threadedly connected to the inside of the retaining ring 10 passes.
[0027] In this embodiment, the outlet 2 and the storage tank 1 are designed to be detachable. The outlet 2 has a conical structure. When the outlet 2 is blocked, it can be removed to clean the outlet 2.
[0028] In this embodiment, the mounting ring 8 is made of stainless steel, and several sets of heating wires 9 are vertically arranged inside the mounting ring 8. The stainless steel material can conduct heat better and transfer heat to the inside of the storage tank 1.
[0029] In this embodiment, the mounting ring 8 is tightly fitted to the storage tank 1, and the retaining ring 10 completely seals the top of the mounting ring 8. The retaining ring 10 can play a protective role by shielding the mounting ring 8.
[0030] In this embodiment, the stirring rod 7 forms a rotating structure inside the storage tank 1 via the motor 6. The stirring rod 7 does not contact the inner wall of the storage tank 1. The motor 6 is turned on to control the stirring rod 7 to rotate slowly, thereby stirring the refining agent and performing periodic drying treatment.
[0031] Example 2
[0032] Based on Example 1, a preferred embodiment of the welding additive manufacturing refining agent addition device provided by this utility model is as follows: Figures 1 to 5 As shown: The surface of the storage tank 1 is threaded with a control ring 13, the bottom of the control ring 13 is slidably connected with a connecting rod 14, the bottom of the connecting rod 14 is fixedly connected with a slide rod 15 that is slidably connected to the conduit 3, and the surface of the conduit 3 is fixedly connected with a limit ring 16.
[0033] In this embodiment, the conduit 3 is a flexible hose, and the connecting rod 14 forms a lifting structure through the control ring 13. Rotating the control ring 13 causes it to move downward along the storage tank 1, thereby driving the connecting rod 14, which is embedded and slidably connected to itself, to descend. When the connecting rod 14 descends, it will push the conduit 3 downward through the slide rod 15, causing the conduit 3 to tilt downward. At this time, the fine agent will flow out from the inside of the conduit 3 to achieve the purpose of addition. When no addition is needed, the control ring 13 can be rotated to make the conduit 3 face upward.
[0034] In this embodiment, the limiting ring 16 is located on the movement trajectory of the slide rod 15. The limiting ring 16 can block the slide rod 15 and prevent the slide rod 15 from slipping off the guide tube 3.
[0035] The working principle and usage process of this utility model are as follows: First, when it is necessary to add a finer agent, the control ring 13 can be rotated to move it downward along the storage tank 1, thereby driving the connecting rod 14, which is embedded and slidably connected to itself, to descend. When the connecting rod 14 descends, it will push the guide tube 3 downward through the slide rod 15, causing the guide tube 3 to tilt downward. At this time, the finer agent will flow out from the inside of the guide tube 3, achieving the purpose of addition. When it is not necessary to add, the control ring 13 can be rotated to make the guide tube 3 face upward. By setting the heating wire 9, in order to prevent the finer agent from getting damp, the heat dissipated by the heating wire 9 heats the storage tank 1. Then, the motor 6 is turned on to control the stirring rod 7 to rotate slowly, thereby stirring the finer agent and performing periodic drying treatment. When it is necessary to inspect the heating wire 9, the screw 12 can be removed to remove the retaining ring 10, and the mounting ring 8 can be taken out from the inside of the storage tank 1, achieving the purpose of disassembling the heating wire 9.
[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
