Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum preforming equipment, in particular to a vacuum preforming device for a carbon fiber wheel hub. Background Art

[0002] Carbon fiber wheel vacuum preforming device is a device used for preforming when manufacturing carbon fiber wheels. It is usually composed of a vacuum chamber, a vacuum pump, a heating element, a control system, etc. The device places carbon fiber cloth or prepreg in a preforming mold, and then uses a vacuum pump to extract the air in the mold under vacuum conditions to achieve close fitting and curing of the carbon fiber material. This preforming process can provide a good shape and performance for the carbon fiber wheel and reduce the complexity of subsequent processing. The control system of the device can monitor and adjust parameters such as vacuum degree and temperature in real time to ensure the accuracy and stability of the preforming process.

[0003] The existing carbon fiber wheel hub vacuum preforming device generally uses a one-way valve to vacuumize. The vacuuming process usually takes a certain amount of time and energy. Before the vacuum degree reaches the requirement, the operator needs to wait for a while, which is very time-consuming and greatly reduces the efficiency of vacuuming. Therefore, we hope to design a carbon fiber wheel hub vacuum preforming device with a new structure to solve this problem. Utility Model Content

[0026] See also Figures 1 to 5The utility model provides a technical solution: a carbon fiber wheel hub vacuum preforming device, comprising: a cabinet 100, a sealing assembly 200 and a pressing assembly 300, the upper side of the cabinet 100 is equipped with a sealing assembly 200 for forming a sealed space, and the upper inner front side of the cabinet 100 is equipped with a pressing assembly 300;

[0027] The cabinet 100 includes a cabinet body 110, a vacuum pump, a vacuum plate 120 and a lock 130. The vacuum plate 120 is installed on the upper end of the cabinet body 110, the lock 130 is installed on the front side of the vacuum plate 120, and the vacuum pump is installed inside the cabinet body 110;

[0028] The sealing assembly 200 includes a pressing frame 210, a sealing cover 220, a mounting frame 230, a stand 240 and a shaft 250. The rear side of the pressing frame 210 is connected to the shaft 250 in a damped rotation manner. The rear side of the sealing cover 220 is connected to the shaft 250 in a damped rotation manner. The shaft 250 is rotatably mounted on the front side of the stand 240 through a support rod 260. The stand 240 is mounted on the rear side of the upper end of the mounting frame 230.

[0029] The clamping assembly includes a base 310 , an electromagnet 320 and a guide rod 330 . The electromagnet 320 is movably mounted on the upper side of the base 310 through the guide rod 330 and a spring.

[0030] See also Figures 1 to 4 The lower side of the vacuum plate 120 is connected to the air inlet of the vacuum pump through a vacuum tube. A cavity is arranged inside the vacuum plate 120. A plurality of evenly distributed air holes are opened downward on the upper side of the vacuum plate 120. By setting the vacuum plate 120, the larger number of air holes can quickly evacuate the air in the transparent cover, and then quickly evacuate the mold with the carbon fiber wheel hub and the vacuum bag, thereby shortening the waiting time.

[0031] A sealing strip 211 with a rectangular structure is fixed in the middle of the lower surface of the pressing frame 210. The lower side of the pressing frame 210 is sealed against the edge of the upper surface of the vacuum plate 120 through the sealing strip 211. The length and width of the pressing frame 210 are the same as those of the sealing cover 220. The movable cover of the sealing cover 220 is installed on the upper side of the pressing frame 210.

[0032] A transparent cover is disposed on the upper side of the sealing cover 220 , the lower surface of the sealing cover 220 is in sealing contact with the upper surface of the pressing frame 210 , and the inner space of the transparent cover is in communication with the upper space of the vacuum plate 120 .

The empty plate 120 evacuates the space between the vacuum plate 120, the pressure frame 210, the sealing cover 220 and the transparent cover. The air inside the opened vacuum bag is quickly evacuated under other effects. After the vacuuming is completed, it is only necessary to start the clamping component 300 to seal the vacuum bag port, and then the sealing cover 220 can be opened to connect the vacuum bag to the wheel hub mold and send it to the next processing procedure. The large number of air holes can quickly evacuate the air in the transparent cover, and then quickly evacuate the mold with the carbon fiber hub and the vacuum bag, shortening the waiting time.

After the user holds the vacuum bag port, the power supply of the electromagnet 320 can be disconnected. Under the action of the spring and the guide rod 330, the entire electromagnet 320 moves upward, and the vacuum bag can be taken out to proceed to the next step of the procedure. The setting of the clamping assembly 300 makes it unnecessary to set a single-way air valve for the vacuum bag, and it can be opened with a larger opening to accelerate the speed of vacuuming.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
