Description

Technical Field

[0001] The utility model relates to the technical field of gradient material manufacturing, in particular to a device for preparing a bionic configuration gradient material. Background Art

[0002] Functional gradient material is a new type of composite material that is a composite of two or more materials and whose composition and structure show continuous gradient changes. It is adapted to the needs of high-tech fields such as the modern aerospace industry and is developed to meet the needs of repeated normal operation under extreme environments. Its design requirements for function and performance change with the change of the internal position of the random component, and are met by optimizing the overall performance of the component. From the perspective of material structure, functional gradient material is different from homogeneous material and composite material. It selects two (or more) materials with different properties, and continuously changes the composition and structure of these two (or more) materials so that their interface disappears, causing the material's performance to slowly change with the change of the material's composition and structure, thus forming a functional gradient material.

[0029] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] The utility model provides a bionic configuration gradient material preparation device. Metal powder falls into a mixing box through a quantitative storage box. The stirring motor drives the stirring blades to mix the metal powder to prevent the gradient material from being faulted during the manufacturing process. Please refer to Figure 1-Figure 5 , including: a preparation mechanism 100, a mixing mechanism 200 and a feeding mechanism 300.

[0031] The preparation mechanism 100 includes a mixing box 110, a feeding pipe 120 and a laser nozzle 130. The bottom discharge end of the mixing box 110 is connected to the laser nozzle 130 through the feeding pipe 120.

[0032] The metal powder is mixed in the mixing box 110 and then enters the laser nozzle 130 through the feeding pipe 120. The metal powder is heated by the laser nozzle 130 and then sprayed out to form a gradient material.

[0033] The mixing mechanism 200 is arranged on the top of the mixing box 110. The mixing mechanism 200 includes a top cover 210, a bracket 220, a stirring motor 230, a stirring shaft 240, a stirring blade 250 and a feed opening 260. The bracket 220 is arranged at the top center of the top cover 210, and the stirring motor 230 is arranged on the bracket 220. The output end of the stirring motor 230 is connected to the stirring shaft 240 extending into the mixing box 110, and the stirring blade 250 is arranged at the lower end of the stirring shaft 240. The feed openings 260 are arranged on both sides of the top cover 210.

[0034] The stirring motor 230 drives the stirring shaft 240 to rotate, and the stirring shaft 240 drives the stirring blade 250 to rotate. The metal powder enters the mixing box 110 through the discharge port 260, and the rotating stirring blade 250 is used to mix the metal powder.

[0035] The material discharge mechanism 300 is connected to the material discharge port 260, and includes a material discharge pipe 310, a hopper 320, a quantitative storage box 330 and an electric control valve 340. The hopper 320 is arranged at the upper end of the material discharge pipe 310, the quantitative storage box 330 is arranged in the middle of the hopper 320, and the electric control valve 340 is arranged on the material discharge pipe 310 between the hopper 320 and the quantitative storage box 330;

[0036] Among them, the metal powder is stored in the hoppers 320 on both sides respectively, and the electric control valve 340 controls the flow of the discharge pipe 310 to control the amount of discharge, so that the metal powder falls into the quantitative storage box 330. The metal powder in the quantitative storage box 330 falls into the mixing box 110 under weight for mixing. The number of discharge mechanisms 300 is customized according to the type and quantity of the required metal powder.

[0037] Since the feeding tube 310 needs to be connected to the feeding port 260 , a plug 350 is provided at the lower end of the feeding tube 310 for easy connection, and the feeding tube 310 is connected to the feeding port 260 via the plug 350 .

[0038] If the metal powder in the quantitative storage box 330 falls into the mixing box 110 at once, it is easy to accumulate, and it takes a long time to stir to mix the powder. For this reason, a driving gear 270 is provided on the stirring shaft 240, shaft holes 280 are provided on both sides of the top cover 210, a slot 360 is provided on the side of the lower end of the discharge pipe 310, and an adjustment mechanism 400 is provided on the shaft hole 280. The adjustment mechanism 400 includes a driven gear 410, a rotating shaft 420, an eccentric shaft 430, a plug plate 440, a hinge seat 450 and a connecting rod 460. The bottom of the driven gear 410 is connected to the shaft hole 280 through the rotating shaft 420, the eccentric shaft 430 is provided on the top of the driven gear 410, the plug plate 440 is inserted in the slot 360, the outer end of the plug plate 440 is provided with a hinge seat 450, and a connecting rod 460 is provided between the hinge seat 450 and the eccentric shaft 430.

[0039] The stirring shaft 240 drives the driving gear 270 to rotate, and the driving gear 270 drives the eccentric shaft 430 to rotate in a circle. The eccentric shaft 430 drives the plug plate 440 to insert and pull in the slot 360 through the connecting rod 460. When inserted, the feed pipe 310 is closed, and when pulled out, the feed pipe 310 is unblocked. As the driving gear 270 continues to rotate, the plug plate 440 performs reciprocating insertion and pulling, so that the powder in the quantitative storage box 330 falls intermittently, so as to avoid the metal powder from falling and accumulating.

[0040] To ensure the sealing effect of the plug plate 440, when the eccentric shaft 430 rotates to a position close to the discharge pipe 310, the plug plate 440 is sealed in the discharge pipe 310, so that the discharge pipe 310 switches back and forth between sealing and unblocking.

[0041] The bottom of the mixing box 110 is provided with supporting legs 140 , and the supporting legs 140 are evenly distributed at the bottom of the mixing box 110 to prop up the mixing box 110 .

[0042] Since the metal powder needs to be weighed to fall, the bottom of the quantitative storage box 330 is conical to facilitate the metal powder to fall along the inclined surface of the cone.

[0043] In order to facilitate observation of the residual metal powder inside, a transparent window is provided on the outer wall of the quantitative storage box 330 , and a scale mark is provided on the transparent window, through which the residual metal powder in the quantitative storage box 330 can be observed.

[0044] During specific use, the metal powder is stored in the hoppers 320 on both sides respectively, and the electric control valve 340 controls the flow of the feed pipe 310 to control the amount of material falling, so that the metal powder falls into the quantitative storage box 330, and the metal powder in the quantitative storage box 330 falls into the mixing box 110 under weight for mixing, and the stirring motor 230 drives the stirring shaft 240 to rotate, and the stirring shaft 240 drives the stirring blade 250 to rotate, and the rotating stirring blade 250 is used to mix the metal powder, and the stirring shaft 240 drives the driving gear 270 to rotate, and the driving gear 270 drives the eccentric shaft 430 to rotate in a circle, and the eccentric shaft 430 drives the plug plate 440 to be inserted and pulled in the slot 360 through the connecting rod 460, and when inserted, the feed pipe 310 is closed, and when pulled out, the feed pipe 310 is unblocked, and as the driving gear 270 rotates continuously, the plug plate 440 performs reciprocating insertion and pulling activities, so that the powder in the quantitative storage box 330 falls intermittently, and the metal powder is prevented from falling and accumulating at once.

[0045] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources.
