发明名称 Method and device for producing shell-shaped, plastic parts reinforced with fibre mats
摘要 The invention relates to a process and a production installation for producing shell-shaped, fibre-reinforced plastic parts. According to the invention, it is intended that the plastic parts can be produced efficiently, in an automated manner which is flexible with respect to the process and workpiece and is operationally reliable. For this purpose, the following process steps are provided: a blank of the endless fibre mat corresponding to a workpiece is placed in an automated manner by industrial robots onto a clamping frame surrounding the female mould and is taken over by the clamping frame in a clamping manner and in such a way that it can slide after itself against a defined resistance. Wide-ranging accessibility required for this is created by a horizontally movable unit, comprising a female mould and a clamping frame, being temporarily moved completely out from the forming press and moved back again into the forming press after completion of loading. The placed blank is sprayed with matrix resin by means of a robot-guided spraying nozzle. By closing the forming tool while maintaining a specifically set tensile stress on the blank, the latter is draped into the female mould without any folds or incipient tears, the blank is thereby formed into the desired shell form, at the same time the matrix resin is pressed into the spaces between the fibres and entrapped air is forced out from them. The resin-impregnated fibre mat is kept in the formed and pressed state for a specifically set time period and, at the same time, the matrix resin within the forming tool is thermally cured. After the opening of the forming tool, the plastic part is removed and trimmed.
