Description

Technical Field

[0001] This invention relates to the field of metal casting, and in particular to a centrifugal casting equipment for bimetallic cylindrical castings. Background Technology

[0002] Bimetallic centrifugal casting is a process that uses centrifugal force to combine two metals with different properties. This product is characterized by using high-quality carbon structural steel as the matrix, with high-strength copper alloy material cast on the inner or outer ring. This combines the properties of steel and copper alloy. The comprehensive mechanical properties of the steel matrix are superior to those of the copper alloy, while the wear resistance and friction reduction properties of the copper alloy are superior to those of steel. This forms a new type of high-performance bimetallic composite material, which enhances its load-bearing capacity while reducing material costs. The product is widely used in high-load, high-temperature, and medium-speed applications.

[0016] Beneficial effects

[0017] 1. This invention proposes a dual-channel casting mechanism adapted for bimetallic centrifugal casting. This mechanism is equipped with independent casting channels for the inner and outer layers of molten metal. Through the independent structural design of the channels, the molten metal is isolated and transported from the source of casting, fundamentally avoiding the problem of mixing and fusion of the two molten metals during the casting process, ensuring the purity of the bimetallic liquid, and laying the foundation for the high-quality bonding of the bimetallic interface.

[0018] 2. The dual-channel casting mechanism of this invention has automatic switching and precise positioning functions, which can realize the automatic switching and replacement of the corresponding channels of the inner and outer layers of molten metal. It completely replaces the traditional manual disassembly, assembly and debugging of channels, effectively avoiding the problems of positioning deviation, cumbersome operation and long auxiliary time caused by manual channel replacement. It greatly saves the auxiliary processing time for channel replacement, improves the continuity and automation of the casting process, and thus significantly improves the overall processing efficiency of bimetallic centrifugal casting. At the same time, it can also reduce the labor intensity of manual operation, reduce the casting defects caused by human operation errors, and improve the standardization and stability of casting production.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1 As shown in the figure, the centrifugal casting equipment for bimetallic cylindrical casting provided by the embodiment of the present invention includes a forming mechanism 100 and a casting mechanism 200, wherein the casting mechanism 200 is used for casting molten metal, that is, the bimetallic molten metal is cast into the interior of the forming mechanism 100 in one go, and the forming mechanism 100 forms a bimetallic cylindrical casting under the action of centrifugal force.

[0023] like Figure 2As shown, the molding mechanism 100 includes a base 111, a housing 101 fixedly mounted on the base 111, a first mounting plate 102 fixedly mounted on the housing 101, a first motor 106 fixedly mounted on the first mounting plate 102, a first connecting plate 107 fixedly mounted at the output end of the first motor 106, a second connecting plate 108 detachably connected to the first connecting plate 107, and a casting mold 109 fixedly mounted on the second connecting plate 108. The casting mold 109 uses integrated resistance heating to achieve temperature changes. The first mounting plate 102 is located on the first motor 106. The first threaded rod 103 is rotatably provided on both sides of the 06, and the first limiting rod is fixedly provided. The end of the first threaded rod 103 is connected to the second motor, which drives the threaded rod to rotate. The second motor is fixed on the first mounting plate 102. The first threaded rod 103 is threadedly fitted with a fire baffle plate 105. The two ends of the fire baffle plate 105 are fixedly provided with connecting plates 104. One connecting plate 104 is threadedly fitted with the first threaded rod 103, and the other connecting plate 104 is slidably fitted with the first limiting rod. The fire baffle plate 105 is also provided with a through hole 110 in the middle position.

[0024] In use, the first motor 106 drives the first connecting plate 107 and the casting mold 109 fixedly connected thereto to rotate synchronously. Under the action of centrifugal force, the outer layer of molten metal is poured first. Under the action of centrifugal force, the outer layer of molten metal is evenly distributed on the inner wall of the casting mold 109 to form an outer layer. The solidification degree of the outer layer of metal is controlled. When a semi-solidified layer is formed on the surface of the outer layer of molten metal, the inner layer of molten metal is poured immediately. Under the action of centrifugal force, the inner layer of molten metal adheres tightly to the inner wall of the outer layer and forms a metallurgical bonding interface with the outer layer of metal.

[0025] The cylindrical casting in this invention is bimetallic, meaning that the outer layer of molten metal is poured first, and the inner layer of molten metal is poured when the outer layer is semi-solidified. Conventional centrifugal casting equipment only has a single material trough. When casting bimetallic metals, the same material trough is used to pour two different types of molten metals sequentially. After the outer layer of molten metal enters the casting mold along the material trough, some molten metal or solidified metal blocks will remain on the material feed trough. If the same material trough is used for feeding again at this time, some of the outer layer of molten metal will be mixed into the inner layer of molten metal, or solidified metal fragments will be carried into the casting mold, which will have a certain impact on product quality. If the material feed trough is changed manually, it is time-consuming and labor-intensive because the temperature is high and manual contact is not possible. Therefore, this embodiment proposes a dual-channel casting mechanism 200, in which the inner and outer molten metals are equipped with separate channels to avoid the mixing of the two types of molten metals during the casting process. In this embodiment, the dual channels can be changed automatically, avoiding manual replacement, saving processing time and improving processing efficiency.

[0026] like Figure 3 and Figure 4As shown, the casting mechanism 200 includes a second mounting plate 201. First brackets 202 are fixedly mounted on both sides of the second mounting plate 201. A transverse bracket 203 is fixedly connected between the two first brackets 202. A second threaded rod 213 is rotatably mounted on the transverse bracket 203. Two moving components 204 are slidably mounted on the transverse bracket 203. Both moving components 204 are threadedly engaged with the second threaded rod 213. The two moving components 204 are fixedly connected by a connecting rod 205. Each moving component 204 has a U-shaped groove, and a positioning rod 209 is fixedly mounted on the U-shaped groove. The U-shaped groove and the positioning rod 209 are used for detachable installation. The ladle includes a cylindrical barrel 212. A fixing ring 211 is provided on the outside of the barrel 212. Connecting ears 210 are rotatably provided on both sides of the fixing ring 211. The two connecting ears 210 are L-shaped, and mating blocks 208 are fixed to the top of each connecting ear 210. Mating holes are provided on the two mating blocks 208. In use, the mating holes on the mating blocks 208 of the ladle are inserted into the positioning rods 209 on the moving assembly 204, achieving a detachable connection between the ladle and the moving assembly 204. A second threaded rod 213 drives the moving assembly 204 to move the ladle to the designated casting position.

[0027] To achieve automatic pouring of molten metal from the ladle, the barrel 212 and the two connecting lugs 210 in this embodiment are rotatably connected. During the casting process, the barrel 212 can tilt to pour the molten metal. This embodiment provides a tilting drive mechanism. Specifically, a first friction wheel 221 is provided at the rotatable connection between the barrel 212 and one of the connecting lugs 210. The first friction wheel 221 is fixedly connected to the barrel 212. A second bracket 206 is fixedly provided on the transverse support 203, and a second friction wheel 221 is rotatably mounted on the second bracket 206. 07. The second friction wheel 207 is driven by the second motor, which is fixedly connected to the second bracket 206. When the second threaded rod 213 drives the ladle to move to the designated casting position, the second friction wheel 207 and the first friction wheel 221 come into contact and fit together. The second motor drives the second threaded rod 213 to rotate, ultimately achieving the tilting and rotation of the barrel 212, which facilitates the pouring out of the internal molten metal. This embodiment only provides one way to rotate the barrel 212. When implementing this technical solution, the barrel 212 may be driven directly by a motor, including but not limited to.

[0028] like Figure 3As shown, a gearbox 214 is provided at one end of the transverse support 203. The gearbox 214 contains a drive source and two synchronously rotating output shafts. One output shaft is coaxial with and fixedly connected to the second threaded rod 213, and the other output shaft is coaxial with and fixedly connected to the first pulley 216 through a connecting assembly 215. A third mounting plate 222 is fixedly provided on the second mounting plate 201. A second pulley 217 is rotatably provided on the third mounting plate 222. A first synchronous belt 218 is synchronously connected between the first pulley 216 and the second pulley 217. When the gearbox 214 is working, the second threaded rod 213 can rotate, and the other connecting assembly 215 can rotate simultaneously.

[0029] To avoid mixing of two molten metals during casting, this embodiment also proposes a dual-channel feed trough for independently supplying different molten metals, such as... Figure 5 , Figure 6 and Figure 7 As shown, the dual-channel material feeding chute includes a rotating assembly 231, which has a U-shaped structure. A first hopper 232 and a second hopper 233 are slidably disposed inside the rotating assembly 231. The first hopper 232 and the second hopper 233 are respectively slidably disposed at the upper and lower ends of the rotating assembly 231 and are installed in opposite directions. The end of the first hopper 232 is connected to a first feeding chute 237, and the end of the second hopper 233 is connected to a second feeding chute 238. The bottom of the first hopper 232 and the second hopper 233 are respectively provided with a first rack 234 and a second rack 236. A first gear 235 is also rotatably disposed on the rotating assembly 231 between the first rack 234 and the second rack 236. The first gear 235 meshes with both the first rack 234 and the second rack 236, thereby realizing the opposite movement of the first hopper 232 and the second hopper 233 through the gear. The first gear 235 is rotatably disposed on the rotating assembly 231 through a rotating shaft 239.

[0030] like Figure 3 As shown, a third motor 219 is fixedly mounted on the second mounting plate 201, and a connecting shaft 220 is fixedly mounted on the output end of the third motor 219, as shown. Figure 7 As shown, a fourth mounting plate 240 is fixedly mounted on the second mounting plate 201. One end of the connecting shaft 220 passes through the fourth mounting plate 240 and is coaxially and fixedly connected to a third pulley 229. A turntable 228 is rotatably mounted on the fourth mounting plate 240. A third pulley 229 is also coaxially and fixedly mounted on the turntable 228. A second synchronous belt 230 is connected between the two third pulleys 229. The third pulley 229 is fixedly connected to the rotating assembly 231.

[0031] In use, the first hopper 232 and the second hopper 233 are used to hold different molten metals. When casting the outer layer of molten metal, the first hopper 232 is rotated to the top, as shown below. Figure 6As shown, the first feeding chute 237 connected to the first hopper 232 is moved forward until the first feeding chute 237 passes through the baffle plate 105. The discharge end of the first feeding chute 237 is located in the casting mold 109. At this time, under the action of the first gear 235, the second hopper 233 will be in a backward retracted state. The ladle at the top of the first hopper 232 pours the outer layer of molten metal into the first hopper 232, and then enters the casting mold 109 along the first feeding chute 237. Under the action of centrifugal force, the casting of the outer metal is completed. After the inner metal is cast, the third motor 219 is driven to rotate the two third pulleys 229, which further rotates the turntable 228. The turntable 228 drives the rotating component 231 to rotate, turning the first hopper 232 to the bottom and the second hopper 233 to the top, and pushes it forward to pour the inner layer of molten metal into the second hopper 233 for casting.

[0032] Because the temperature of the molten metal in the first hopper 232 and the second hopper 233 is high, manual pushing poses a certain risk. Therefore, this embodiment is equipped with a dedicated pushing mechanism to push the first hopper 232 and the second hopper 233. The first hopper 232 and the second hopper 233 move in opposite directions, that is, one extends and the other retracts, to avoid interference between the two material channels. Specifically, as shown... Figure 6 As shown, a push rod 226 is slidably mounted on the fourth mounting plate 240. A push plate 227 is fixedly mounted on one end of the push rod 226, and a vertical plate 225 is fixedly mounted on the other end of the push rod 226. A sliding rod 223 is fixedly mounted between the third mounting plate 222 and the fourth mounting plate 240, and a third threaded rod 224 is rotatably mounted. Figure 3 As shown, one end of the third threaded rod 224 is coaxial with and fixedly connected to the second pulley 217, the vertical plate 225 is threadedly engaged with the third threaded rod 224, and is slidably engaged with the slide rod 223.

[0033] Combination Figure 3 and Figure 6As shown, in use, when the gearbox 214 is working, the second threaded rod 213 and the first pulley 216 can rotate synchronously. The first pulley 216 realizes the synchronous rotation of the second pulley 217 through the first synchronous belt 218. The second pulley 217 is coaxial with and fixedly connected to the third threaded rod 224, ultimately realizing the synchronous rotation of the second threaded rod 213 and the third threaded rod 224. The rotation of the third threaded rod 224 realizes the lateral movement of the vertical plate 225. The vertical plate 225 drives the push plate 227 to move laterally, realizing the push of the first hopper 232 or the second hopper 233 in front of the push plate 227. The gearbox 214 simultaneously drives the second threaded rod 213 and the third threaded rod 224. 4. Rotation: The ladle on the second threaded rod 213 and the push plate 227 on the third threaded rod 224 move synchronously. When the ladle moves toward the casting position, the push plate 227 pushes forward synchronously, pushing the first hopper 232 or the second hopper 233 forward until the first feed chute 237 or the second feed chute 238 extends into the casting mold 109 to cast the molten metal. After the molten metal in the ladle is cast, the ladle moves away from the casting position, and the push plate 227 retracts to avoid the push plate 227 obstructing the rotation of the rotating component 231. The first hopper 232 or the second hopper 233 move in opposite directions under the action of the first gear 235, that is, one extends and the other retracts.

[0034] A casting method for a centrifugal casting equipment for bimetallic cylindrical castings includes the following steps: S1: First, the outer layer of molten metal is injected into the corresponding ladle. Then, the ladle is controlled to move over the casting position. The pusher plate 227 pushes the first hopper 232 forward. The first feed chute 237 extends into the casting mold 109. The outer layer of molten metal enters the casting mold 109 and completes casting under the action of centrifugal force. S2: When the outer metal is in a semi-solid state, the inner metal liquid is injected into the corresponding ladle. The rotating component 231 is flipped so that the second hopper 233 rotates to the top. Then, the ladle is controlled to move towards the casting position. The push plate 227 moves the second hopper 233 forward, and the first hopper 232 will retract until the second feed chute 238 extends into the casting mold 109. The inner metal liquid enters the casting mold 109 and fuses with the outer metal under the action of centrifugal force to complete the bimetallic casting.
