Compound material forming method and apparatus

Abstract

The present invention discloses compound material forming method and apparatus. The method includes mounting mold, pressing the material inside the mold, taking out the mold from the press, stoving the mold inside a stove to cure the material inside the mold and other steps. The special apparatus includes a frame, a telescopic device on the frame, a pressing block connected to the lower end of the telescopic device and with central hole, a central locator in the bottom of the frame, a central cylinder set on the frame and connected to the central locating shaft of the central locator and a mold set below the pressing block. The present invention has high utilization rate of compound material, simple compound material forming process and saving in raw material, and may be used in producing different compound materials.

Description

Technical field: [0001] The invention relates to a molding method and a special device for composite materials. Background technique: [0002] When processing cork coils, it is necessary to place the threading shaft (with a diameter of more than 200 mm) for positioning, support and guidance in the cork blank. The existing methods are "perforated" and "embedded". The punching type is to make the cork blank into a cylindrical shape, use a special puncher to punch a hole in the center of the cork blank, and then pass the threading shaft into the cork blank. The cork is soft and has a large friction coefficient, so it is difficult to punch holes. A lot of waste (cork chips) will be formed during the process. This method takes time (time) and consumes materials (materials), which does not meet the requirements of building a conservation-oriented society; Inside, and then press the cork blank, this method saves materials, but it needs to prepare a lot of feeding shafts (the cork ...

The punching type is to make the cork blank into a cylindrical shape, use a special puncher to punch a hole in the center of the cork blank, and then pass the threading shaft into the cork blank. The cork is soft and has a large friction coefficient, so it is difficult to punch holes. A lot of waste (cork chips) will be formed during the process. This method takes time (time) and consumes materials (materials), which does not meet the requirements of building a conservation-oriented society; Inside, and then press the cork blank, this method saves materials, but it needs to prepare a lot of feeding shafts (the cork blank needs to have a process of solidification, molding and elimination of internal stress stability, and it will take more than 2 days to process at the fastest) turnover, and processing The center positioning of the threading shaft is difficult to control, and deviations will be formed during pressing, which greatly reduces the utilization rate of cork blanks and the process is very complicated
