Abstract

The invention relates to vacuum forming equipment, and relates to the field of hot pressing forming. The vacuum forming equipment mainly aims at solving the technical problem that existing hot pressing forming equipment is relatively complex in structure and higher in cost. According to the technical scheme, the vacuum forming equipment comprises a flexible bag body internally provided with a molding cavity; and the flexible bag body is provided with a vacuum pumping opening communicated with the interior so as to vacuumize the interior of the flexible bag body, the flexible bag body deforms under the effect of external air pressure, and workpieces in the molding cavity are subject to extrusion forming. According to the technical scheme, a large rigid vacuum tank can be replaced with the flexible bag body, and the cost of the flexible bag body is low; and in addition, as the workpieces in the bag body are subject to extrusion forming through barometric pressure, a pressure applying mechanism is omitted compared with the prior art, and therefore the vacuum forming equipment is more simplified in structure and lower in cost.

Description

technical field [0001] The invention relates to the technical field of thermoforming, in particular to a vacuum forming device. Background technique [0002] In the field of composite material forming technology, in order to improve the performance of the composite material structure after forming, the following measures are mainly adopted: (1) remove the binder and the gas between the composite material layers by vacuuming; (2) make the material Composite molding and maintain tightness; (3) Use a curing agent that can improve the strength of the resin, but often requires high temperature curing conditions. [0003] However, due to the constraints of the composite material structure, it is usually difficult to form large-sized and complex-shaped composite material structural parts, such as the radome of the early warning aircraft, the blades of the wind turbine, and the wings of the aircraft that require light weight and high strength, etc. , often requires large rigid vacu...
