Problems solved by technology

[0005] The reciprocating composite profile extrusion production method and device can realize large-scale FRP profiles that meet the length requirements and meet the needs of long-span bridge construction, but some waste materials are still generated from time to time in this production method
At the same time, it is difficult to tow and transport large profiles with a length of about 3 kilometers. At the same time, the quality of profiles will be unbalanced due to the difference in tension between the main vehicle and auxiliary vehicle of the tractor during the production process.

Embodiment Construction

[0028] Such as figure 1 As shown, the large-scale profile pultrusion production device can be used for on-site production of FRP large-scale composite profiles. The large-scale profile pultrusion production device includes a pultrusion traction mobile tool, and the pultrusion traction mobile tool is a pultrusion traction truck 40 , The truck has a platform that is longer than the conventional vehicle body, and the glass fiber winding creel 10, the dipping and preforming equipment 20, and the hot mold extrusion molding machine 30 are arranged in sequence on the platform.

[0029] In the production of FRP composite profiles, the glass fiber skeleton model of the profile is first formed, then dipped and preformed to form the basic structure of the required profile, and then extruded by the thermal molding process, and the extrusion is carried out by a continuous pultrusion tractor. The profile 50 is stretched and formed, and one end of the produced profile is fixed on a fixing me...

Abstract

The invention relates to a large section pulling and extruding type production method and a set thereof. The production method includes: adopting a pulling and extruding drawing tool provided with a fixed section extruding production device; when the section extruding production device working, the pulling and extruding drawing tool moving along the direction opposite to the section extruding direction. The invention eliminates the defect that the elongated large section is hard to move. The production method and the set realize the large section production on site and stable quality control in a way that the extruding device extends. The production is fast and convenient; the transportation is smooth and the waste due to improper cutting of large section is avoided.

Description

technical field [0001] The invention belongs to the field of production technology and equipment of large-scale composite profiles, and in particular relates to a pultrusion-type production method and device for FRP composite large-scale profiles. Background technique [0002] Fiber-reinforced composite material FRP is a new type of structural material that has been widely used in civil and bridge engineering in recent years. FRP has the advantages of high strength, light weight, and corrosion resistance. At present, it has been well applied in the reinforcement and reinforcement of bridges and other structures, and the enclosure and anticorrosion. As the superior performance of FRP material is gradually recognized by the engineering community, many bridge projects abroad have begun to apply it to bridges between centers, especially long-span bridges. Since the 1970s, FRP materials have been tried to be applied in bridge engineering. Britain, the United States and Israel ...
