Abstract
The utility model discloses a material-rolling core mould of a carbon fiber bicycle frame. The material-rolling core mould consists of an upper tube material-rolling core mould, a middle tube material-rolling core mould, a lower tube material-rolling core mould and a head tube material-rolling core mould which are formed by foaming of EPS (Expandable Polystyrene) foams, wherein the two ends of the lower tube material-rolling core mould are respectively connected with the upper tube material-rolling core mould and the middle tube material-rolling core mould in a combined manner by virtue of a male joint and a female joint; the head tube material-rolling core mould is formed by foaming of TPU (Thermoplastic Polyurethane), is in a two-sheet type structure, and is coated at a connected end of the upper tube material-rolling core mould and the lower tube material-rolling core mould by virtue of the male joint and the female joint which are matched. The material-rolling core mould disclosed by the utility model avoids conditions of yarn clamping and hungry joint accumulation, greatly improves a phenomenon that the inner wall of the bicycle frame made from the carbon fiber composite material is not smooth, strengthens product rigidity and stability, and can obviously improve qualified rate of finished products of the bicycle frame made of the carbon fiber composite material.
Description
Technical field
The utility model relates to a kind of carbon fiber coiled strip core, particularly a kind of carbon fiber bicycle vehicle frame coiled strip core.
Background technology
Carbon fibre composite is because specific strength, specific modulus are high, and excellent anti-corrosion performance has good fatigue performance simultaneously, is therefore widely applied in fields such as Aero-Space, building, sports goods.Carbon fibre composite bicycle is the development trend of current bicycle, but due to the profile factor of bicycle itself and the moulding process of carbon fiber product, scrapping very easily appears in carbon fibre composite bicycle in process of production, and its most of reason occurs in coiled strip workshop section.
The problems such as yarn clipping, gas leakage, infolding, long-pending starved easily occur in carbon fibre composite bicycle forming process, had a strong impact on presentation quality and the yield rate of product, the reason that above problem occurs is exactly that coiled strip is lack of standardization, therefore need a kind of coiled strip core of invention.
Utility model content
The purpose of this utility model is to provide a kind of bicycle carrier made of carbon fiber composite coiled strip core, and it can make bicycle coiled strip tight, and appearance and size is accurate, moulding inner wall smooth, the scrappage of reduction product.
For realizing above-mentioned technical purpose, the utility model provides a kind of carbon fiber bicycle frame coiled strip core, it is realized by following means: a kind of bicycle carrier made of carbon fiber composite coiled strip core, is made up of upper pipe coiled strip core, middle pipe coiled strip core, lower pipe coiled strip core and head tube coiled strip core; Wherein go up pipe coiled strip core, middle pipe coiled strip core and lower pipe coiled strip core and adopt eps foam foaming, the head tube end of upper pipe coiled strip core has male joint, the five-way end of middle pipe coiled strip core has male joint, head tube end and the five-way end of lower pipe coiled strip core are all established female joint, and lower pipe coiled strip core two ends are connected by above-mentioned male joint, female joint with upper pipe coiled strip core, middle pipe coiled strip core respectively; Described head tube coiled strip core adopts TPU foaming, and it be two-piece type structure, and the male joint by cooperation and female joint are coated on the link of upper pipe coiled strip core and lower pipe coiled strip core.
Effect of the present utility model is: the utility model has designed and comprised carbon fiber bicycle frame coiled strip core, this coiled strip technique can be coated according to product size accurately, yarn clipping and long-pending starved situation are avoided, greatly improve the rough phenomenon of carbon fibre composite vehicle frame inwall, strengthen product rigidity and stability, can significantly improve the product qualified rate of bicycle carrier made of carbon fiber composite.
