Device and method for warm forming of metal and carbon fiber prepreg composite material components

Abstract

The invention discloses a warm-hot forming device and method for a metal and carbon fiber prepreg composite material component in the field of lightweight composite material forming and processing. An outer blank holder is arranged between a female mold and a male mold. The middle of the outer blank holder is provided with a downwards concave step positioning groove. The top of the step positioning groove can contain a steel plate, and an inner blank holder is placed at the bottom of the step positioning groove. The upper surface of the inner blank holder can contain a carbon fiber prepreg blank. A pushing plate is arranged under the male mold. The top ends of a first outer blank holder pushing rod and a second outer blank holder pushing rod can upwards jack the outer blank holder, and the bottom ends of the first outer blank holder pushing rod and the second outer blank holder pushing rod are fixedly connected to the pushing plate. The top ends of a first inner blank holder pushing rod and a second inner blank holder pushing rod can upwards jack the inner blank holder, and the bottom ends of the first inner blank holder pushing rod and the second inner blank holder pushing rod are each connected with a hydraulic cylinder. A third hydraulic cylinder is connected under the pushing plate. Large adjustable constraint resistance is applied to the steel plate. By means of the adjustable constraint resistance with a small effect on the carbon fiber prepreg blank, two heterogeneous component materials have the mutual matching forming capacities, and warm forming and hot forming are completed in a one-time stamping stroke.

Description

technical field

[0001] The invention belongs to the field of lightweight composite material molding and processing, and specifically relates to a method and device for manufacturing metal and carbon fiber prepreg composite components, which are suitable for the composite of metal steel plates and carbon fiber prepregs composed of metal steel plates and carbon fiber prepregs. Batch manufacturing of material components (Steel / CFRP components for short). Background technique

[0002] Two types of lightweight materials are widely used at present, one is high / ultra-high strength steel plate, because there are problems such as complex forming process, high manufacturing cost, large forming force required, severe springback, and limited thickness reduction, etc. Lightweight potential; the second is Carbon Fiber Reinforced Plastic (CFRP), although it has high specific strength, specific stiffness and low density, but it has low elongation, poor fracture toughness, long production cy...

Embodiment Construction

[0022] see figure 1 , the warm forming device of the metal and carbon fiber prepreg composite material component of the present invention has an upper mold part and a lower mold part, and the upper mold part and the lower mold part constitute a stamping forming unit. Wherein, the upper mold part includes an upper mold fixed plate 44 , a mold handle 45 , and a die 10 . The lower surface of the die 10 is a binder surface, and a downwardly protruding calendering bead 46 is arranged on the binder surface. The top of the die 10 is fixedly connected to the upper mold fixed plate 44, and the upper mold fixed plate 44 is fixedly connected to the die handle 45, and the die handle 45 is connected to the press slide block ( figure 1 omitting the press slider) to be connected, and the press drives the mold handle 45 and the upper mold fixing plate 44 to move vertically up and down, thereby driving the die 10 to move vertically up and down.
