Description

Technical Field

[0001] This invention relates to the field of carbon-carbon composite material processing technology, specifically to a carbon-carbon composite workpiece curing processing device. Background Technology

[0002] Carbon-carbon material preparation mainly involves two methods: chemical deposition and liquid-phase impregnation. Liquid-phase impregnation involves immersing a carbon fiber preform in a liquid impregnating agent. Vacuum and pressure are used to allow the impregnating agent to penetrate the pores of the preform. Following a series of processes including curing, carbonization, and graphitization, a carbon-carbon composite material is obtained. Autoclave curing of carbon fiber prepreg involves stacking flexible carbon-carbon composite materials, heating and pressurizing them, and then pouring in an impregnation curing liquid to cure the surface.

[0003] Regarding the aforementioned technologies, when preparing carbon-carbon materials and performing impregnation and curing processes, the higher the number of carbon fiber preforms per unit volume in the impregnation and curing device, the higher its preparation efficiency. However, if the carbon fiber preforms are placed tightly together, the impregnation liquid will not easily penetrate into the carbon fiber preforms. Therefore, it is necessary to separate the carbon fiber preforms. During the impregnation process, how to ensure that carbon fiber preforms of different shapes are cured simultaneously and efficiently, and ensure that they do not come into contact with each other, and that the impregnation process is stable and does not tip over or overlap, are problems that need to be solved. Summary of the Invention

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows: a carbon-carbon composite workpiece curing processing device, comprising a curing tank body and a top cover disposed at the center of the top of the curing tank body; a pressurizing mechanism is disposed at the center of the top cover, and a heating mechanism is disposed at the bottom of the curing tank body; a feeding mechanism for feeding and fixing carbon-carbon composite workpieces is disposed between the pressurizing mechanism and the heating mechanism inside the curing tank body; the pressurizing mechanism includes a rotating base disposed at the bottom of the curing tank body, and a mesh cylinder is vertically disposed on the rotating base; a linear drive component with its front end driven downward is disposed above the top cover, and the front end of the linear drive component passes through the top cover and is connected to a device inside the curing tank body for pressing stacked flexible carbon-carbon composite workpieces. The material is pressurized by a pressure block; the feeding mechanism includes an annular grid top plate fixedly installed in the upper part of the curing tank and an annular grid bottom plate installed in the lower part of the curing tank. The grid bottom plate is located directly below the grid top plate and its inner circle is fixedly connected to the outer edge of a circular rotating base; multiple discharge components are arranged in a ring between the grid bottom plate and the grid top plate.

[0006] The beneficial effects of this invention are as follows: by using the discharge component in the feeding mechanism to separate and rationally place each irregular workpiece, the workpieces are prevented from contacting each other while maximizing the use of the curing tank space. At the same time, the curing process of carbon fiber prepreg material can be completed in the middle of the tank.

[0007] As a further improvement of the present invention, the technical problem to be solved is that the fan-shaped space formed between the grid plates may still cause the workpieces therein to sway and tilt.

[0010] As a further improvement of the present invention, the technical problem to be solved is that the height of the fan-shaped space formed between the grid plates is fixed, and short workpieces still cannot fully utilize this space.

[0015] The beneficial effects of the above improvements are as follows: the top cover, which can be rotated and opened in the center, helps the staff to quickly put the carbon fiber prepreg material into the center for curing while the pressurizing mechanism is being quickly removed.

[0016] As a further improvement of the present invention, the technical problem to be solved is: it is inconvenient for staff to understand the internal processing conditions of the curing tank.

[0017] To solve the above-mentioned technical problems, the present invention further improves the technical solution by providing an observation window on the feeding channel door for observing the internal processing of the curing tank.

[0018] The beneficial effect of the above improvements is that they provide an observation window that facilitates the observation of the internal situation.

[0019] As a further improvement of the present invention, the technical problem to be solved is: how the heating mechanism specifically heats the inside of the curing tank.

[0020] To solve the above-mentioned technical problems, the present invention further improves the technical solution as follows: the heating mechanism includes an electric heating element disposed at the lower part of the curing tank body, and an annular heating plate for heating the curing tank body is disposed at the bottom of the curing tank body, and the electric heating element supplies power and heat to the annular heating plate.

[0021] The beneficial effect of the above improvement is that the annular heating plate installed inside the tank is heated by an electric heating device.

[0022] As a further improvement of the present invention, the technical problem to be solved is: how to monitor the internal temperature of the curing tank in real time.

[0023] To solve the above-mentioned technical problems, the present invention further improves the technical solution by providing a temperature measuring element at the top of the curing tank for monitoring its real-time internal temperature.

[0024] The beneficial effects of the above improvements are: the installation of temperature measuring devices, such as industrial thermometers, to monitor the internal temperature of the tank in real time.

[0025] As a further improvement of the present invention, the technical problem to be solved is that after the impregnation curing liquid inside the curing tank is poured, it will accumulate inside the tank, which is inconvenient for subsequent processing operations.

[0026] To solve the above-mentioned technical problems, the present invention further improves the technical solution by providing a draining device for quickly discharging the impregnation and curing liquid at the bottom side of the curing tank body; the draining device includes a drain pipe connecting to the inside of the curing tank body and a valve disposed in the drain pipe and controlling its opening and closing.

[0027] The beneficial effect of the above improvement is that the impregnation and curing liquid inside the tank can be discharged in a timely manner through the drain pipe with a valve.

[0028] As a further improvement of the present invention, the technical problem to be solved is: how the linear drive component specifically implements linear drive operation.

[0029] To solve the above-mentioned technical problems, the present invention further improves the technical solution by adopting a hydraulic cylinder as the linear drive component.

[0056] The working principle of this device is as follows: First, the operator places the carbon fiber prepreg material into the mesh cylinder inside the tank by opening the top cover. The pressure block on the pressurizing mechanism pressurizes and cures the superimposed prepreg material. Then, the loading channel door is opened, the mesh bottom plate is rotated, and the workpiece to be processed is placed between the two grating plates. The handle is operated to slide the inner end of the grating plate along the wall of the mesh cylinder, and the gap between the grating plates is adjusted to ensure that the workpiece is clamped and fixed. Multiple limiting rods and limiting struts can also be used to further limit and fix the workpiece between the two grating plates. Finally, the loading channel door is closed and the heating mechanism is started to complete the heating, pressurizing, and curing process of the carbon-carbon composite workpiece.
