Fiber reinforced wallboard type sectional material composite extruding device and extruding method thereof

Abstract

The invention discloses a fiber reinforced wallboard type sectional material composite extruding device and an extruding method thereof. The composite extruding device comprises a composite extrudingmold and a fiber traction device; the composite extruding mold comprises a flow guiding plate, an upper mold, a lower mold, a feeding plate and a mandrel; the upper mold is provided with a second flowdividing hole which is internally provided with a second flow dividing bridge; one end of the second flow dividing bridge and one end of a first flow dividing bridge are each provided with a feedingplate clamping groove; the feeding plate is connected in the two feeding plate clamping grooves in a clamped manner; the feeding plate is provided with a plurality of fiber feeding channels; and the other end of the second flow dividing bridge is connected with the mandrel which is provided with a through hole parallel with the sectional material extruding direction. According to the composite extruding device and the extruding method thereof, a sectional material can be continuously reinforced at the assigned position of the cross section of the sectional material, and continuous and composite extruding is achieved; and meanwhile, compared with a traditional fiber particle mixed blank material, a conventional blank material is used by the fiber reinforced wallboard type sectional materialcomposite extruding device, the production cost is reduced, and the abrasion resistance of a mold is also improved.

Description

technical field [0001] The invention relates to the technical field of metal extrusion, in particular to a composite extrusion device and an extrusion method for fiber-reinforced wall plate type materials. Background technique [0002] For economical and environmental reasons, particularly in the automotive and aerospace industries as well as in construction, the lightweighting strategy of profiles has become an important aspect of structural part design. On the one hand, reducing the overall weight of the vehicle will reduce fuel consumption and carbon dioxide emissions; on the other hand, from a safety point of view, structural parts require better mechanical properties. The development of hybrid structural parts is a feasible method to meet this demand. The design of hybrid structural parts can realize the combination of mechanical properties and physical and chemical properties of different materials. Currently, existing extrusion processes for producing hybrid structur...

Problems solved by technology

Among them, the profiles produced by discontinuous co-extrusion cannot be continuously reinforced; the co-extruded billet is the inner and outer package of two materials, which requires additional processing and manufacturing before extrusion, which is cumbersome and expensive to produce; the co-extruded fiber billet , it is necessary to uniformly integrate a large number of fine fibers into the interior of the billet when manufacturing the billet, which is difficult to manufacture and high in cost, and the mold wear is serious during extrusion
