Description

Technical Field

[0001] The invention relates to the field of aluminum-based composite plate production equipment, and in particular to a device for double-layer casting continuous carbon fiber reinforced aluminum-based composite plates. Background Art

[0002] Carbon fiber reinforced aluminum-based composite materials are aluminum-based composite materials with aluminum or aluminum alloy as the matrix and reinforced with low-density, high-strength, and high-modulus carbon fibers. The fiber arrangement and distribution can be designed in one-dimensional, two-dimensional, or three-dimensional distribution according to the performance characteristics of the component. The performance of carbon fiber reinforced aluminum-based composite materials depends on the type, content, distribution, composition of the matrix aluminum alloy, and preparation method of the fiber. This material has excellent comprehensive properties such as high specific strength, high specific modulus, good thermal conductivity and electrical conductivity, high temperature resistance, wear resistance, and small thermal expansion coefficient. The performance of carbon fiber reinforced aluminum can be obtained by optimizing the content and distribution of the combined fibers according to the design performance requirements. It is an ideal structural material for aerospace technology. However, when the aluminum liquid is cast, due to its relatively viscous and slow flow, part of the aluminum liquid often contacts the air during distribution to form oxide impurities. Later, when it solidifies to form an aluminum-based composite plate, it often causes the overall quality of the aluminum substrate to decrease. Therefore, we propose a device for double-layer casting of continuous carbon fiber reinforced aluminum-based composite plates to solve the above-mentioned problems. Summary of the invention

[0007] Preferably, a threaded rod passes through the middle of the skateboard, the threaded rod is threadedly connected to the skateboard, one end of the threaded rod is fixedly connected to a servo motor, and the servo motor and the threaded rod are installed on the top of the upper template.

[0008] Preferably, guide frames are installed in the middle of the front and rear sides of the roller frame, and openings are formed on both sides of the adjacent ends of the guide frames.

[0010] Preferably, side openings are installed in the middle of the front and rear ends of the base frame, and evenly distributed guide rollers are provided on the side openings and the upper and lower parts of the guide frame. Electric motors are installed on the ends of the guide rollers, and inner sealing gates are installed inside the side openings.

[0011] Preferably, a mounting plate is installed in the lower part of the base frame, a pump body is installed on one side of the top of the mounting plate, a vacuum pump is installed on the other side of the top of the mounting plate, and both the pump body and the vacuum pump are installed with connecting pipes and conduits.

[0012] Preferably, the pump body is connected to a cryogenic gas tank via a connecting pipe, the ends of the conduits all pass through the bottom of the top bin, valve bodies are installed inside the conduits, and the conduits are communicated with the inside of the top bin.

[0013] Preferably, a top bin is installed on the top of the base frame, a feed pipe is installed in the middle of one end of the top bin, and a sealing door is connected to the other end of the top bin through a hinge.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. Before casting molten aluminum, people can first close the sealing door and the inner sealing gate of the side port, and then start the vacuum pump. The air inside the top bin can be extracted through the operation of the vacuum pump, so that the inside of the top bin is in a negative pressure state. At this time, the hydraulic rod is started, and the upper template and the lower template are brought close through the operation of the hydraulic rod to complete the template merger and the closing of the side plate. At this time, molten aluminum is injected into the mold cavity through the pump group. At this time, the inside of the mold cavity is also in a negative pressure state, which is convenient for the rapid injection of molten aluminum. At the same time, it can prevent the molten aluminum from being in contact with the air for a long time before solidification, generating oxides, which are mixed in the composite aluminum substrate during subsequent solidification, affecting the quality of the finished product, which is beneficial to practical use.

[0015] 2. Before production, the inner sealing gate inside the side port is opened, and the carbon fiber prefabricated mesh layer is inserted into the inside through the side port on one side. The carbon fiber prefabricated mesh layer can be transported through the side port and the guide roller inside the guide frame. The openings on both sides of the mold cavity can be closed by the side plates on both sides of the carbon fiber prefabricated mesh layer to achieve the blockage of the mold cavity and avoid liquid leakage. At the same time, the position of the carbon fiber prefabricated mesh layer can be adjusted by driving the side plates on both sides by using the guide roller. At the same time, the carbon fiber prefabricated mesh layer can be set up through the side plates, so that the carbon fiber prefabricated mesh layer can be centered inside the mold cavity, so that the aluminum liquid can completely wrap the carbon fiber prefabricated mesh layer, which is beneficial to improve the overall bonding of the composite aluminum substrate after molding.

[0016] 3. Before pouring, people can start the servo motor, which can drive the threaded rod to rotate through the work of the servo motor, and the rotation of the threaded rod can drive the slide plate to move. When the slide plate moves, it will drive the side block and the push plate to move through the connecting rod. The movement of the push plate inside the mold cavity can realize the adjustment of the actual mold cavity size during pouring, so that people can manufacture composite aluminum substrates of different lengths according to actual needs, reduce the subsequent cutting process operation, and facilitate practical use.

[0017] 4. During pouring, people can drive the driving gear to rotate through the reduction motor, and the driving gear can use the gear ring engaged with it to drive the roller frame to rotate. When the roller frame rotates, its internal structure will be driven by the fixed plate to rotate synchronously. When the upper template and the lower template are driven to rotate, the aluminum liquid injected into the mold cavity will be quickly dispersed to the part of the mold cavity away from the injection port by the centrifugal force during rotation, so that the injection speed of the aluminum liquid can be further improved, thereby avoiding the situation that the aluminum liquid is easy to solidify partially first due to its poor viscosity and fluidity, affecting the molding quality of the composite aluminum substrate, and at the same time, it can be conducive to the stable combination of the aluminum liquid and the carbon fiber prefabricated mesh layer inside the mold cavity.

[0018] 5. After the aluminum liquid is injected, low-temperature inert gas can be injected into the top bin through the pump body. The low-temperature gas can accelerate the solidification of the aluminum liquid. After the composite aluminum substrate is formed, the low-temperature gas is extracted and recovered through the pump body. Then people can open the sealing door. At this time, the hydraulic rod is controlled to shrink slightly to separate the upper template from the lower template by a distance, and the servo motor is started. The push plate is driven to move by the servo motor and the threaded rod. The push plate can push the composite aluminum substrate to assist in demoulding the composite aluminum substrate, and push the formed composite aluminum substrate out of the aluminum-based composite plate production device to help people complete the unloading work.
