Problems solved by technology

[0005] The disadvantages of the existing hot-extruded polymer material preparation method are: 1. The hot-extruded molten polymer material enters the vacuum setting mold for cooling and molding, and the polymer material product has low density and poor mechanical properties, so it is not suitable for manufacturing surface pressing patterns. The product
2. It is not suitable for the manufacture of composite materials composed of multiple materials
3. It is not suitable for the manufacture of composite materials with metal plates inside
4. The existing hot extrusion process cannot change the arrangement of molecules inside the polymer material
5. The existing roll forming is mostly used for the deformation and rolling of metal materials, and there is no report on the combined use of hot extrusion polymer material forming and roll forming

Abstract

The invention provides a preparation method of a hot-extruded high molecular material by means of rolling and forming, which comprises the following steps of: (1) transporting molten state high molecular material into a performing mould through an outlet mould by a high molecular material hot-extruding machine; (2) performing the molten state high molecular material with the performing mould; (3) cooling and forming the performing hot high molecular material product through a cooling device; (4) leading the cooled and formed hot high molecular material product to enter into a traction apparatus, and transporting the hot high molecular material product into a rolling and forming machine through the traction apparatus; and (5) rolling the upper surface of the hot high molecular material product through an upper forming roller of the rolling and forming machine, rolling the lower surface of the hot high molecular material product through a lower forming roller of the rolling and forming machine, and pressuring in a rolling way through the upper forming roller and the lower forming roller to roll and shape the hot high molecular material product.

Description

Field of invention: [0001] The invention relates to a preparation method and equipment for combining thermal extrusion molding and roll molding of polymer materials. Background technique: [0002] The existing preparation method of hot-extruded polymer material is that the hot extruder extrudes the molten polymer material through the mold, and the molten polymer material enters the vacuum setting mold to absorb the molten polymer material to the surface of the mold by vacuuming. Forming, the molten polymer material adsorbed on the surface of the mold is cooled and shaped by cooling. [0003] The existing cold-bending rolling metal sheet forming is to use a plurality of rolls to pass the metal material through the change of the roll pattern to realize the cold-bending forming of the metal sheet. [0004] Existing hot rolling roll forming presses the high-temperature softened metal material into shape through roll pressure. [0005] The disadvantages of the existing hot-extr...
