Temperature automatic regulating and controlling device for short-cut resin-based fiber reinforced plastic prepreg forming process

Abstract

The invention discloses a temperature automatic regulating and controlling device for short-cut resin-based fiber reinforced plastic prepreg forming process. The device comprises a mechanical structure part and an electric appliance control part, wherein the mechanical structure part comprises a connecting plate, one side of the connecting plate is fixedly connected with a die sleeve, a die sleevebody is connected in the die sleeve through threads, one end of the die sleeve body is connected with a correcting sleeve, and the other end of the die sleeve body is connected with a cold blank impact extrusion die. The correcting sleeve is in linear connection with an impact extrusion device through threads, the outer periphery of the cold blank impact extrusion die is sleeved with an outer sleeve, and one end of the outer sleeve is connected with the die sleeve body. The temperature automatic regulating and controlling device has the advantages of being high in independence, is connected with equipment and facilities through a simple structure, and can be expanded and transformed during design according to the structural form of the equipment used, thus being capable of being expandedto application fields of other industries; and meanwhile, the installation is convenient, flexible and reliable.

Description

technical field [0001] The invention relates to the technical field of resin-based fiber-reinforced plastic prepreg extrusion molding technology, in particular to an automatic temperature control device for the molding process of chopped resin-based fiber-reinforced plastic prepreg. Background technique [0002] At present, with the deepening and development of the application of resin-based fiber-reinforced plastic prepreg composite materials, the molding methods of such materials are also constantly evolving and upgrading. At this stage, domestic resin-based chopped fiber reinforced plastic prepreg composite products are columnar Forming is mostly realized by punching and extrusion, and in the process of punching and extrusion, due to improper temperature control, the product may shrink too much, or expand too much, or the mechanical performance index is not high enough, which directly affects the appearance and quality of the product, making Product features are insuffici...
