Abstract
The invention relates to an aluminum-cap-shell safety helmet and a manufacturing process. The process includes that a cap shell is directly formed through a stretching and rolling process by adopting an aluminum alloy sheet, a cap shell product is obtained through punching, blanking and rolling via treatment of surface decontamination, heat tinting, polishing, plating and the like, adhesion agents are painted on the reverse side of the aluminum cap shell which is placed in a foaming mould for Styrofoam foaming, the aluminum cap shell is enabled to be combined with Styrofoam, arc ribs are longitudinally penetratingly arranged in two sides of the middle of the aluminum cap shell, and bending covered edges are inclining downwardly are respectively arranged in inner edges of hollow spaces in the aluminum cap shell. The safety helmet is made of the aluminum cap shell, ductility of aluminum alloy is fully utilized, the arch ribs are penetratingly arranged in the surface of the cap shell, the strength of the safety helmet is greatly increased, attractiveness and coolness in forming are greatly improved, the bending covered edges are arranged in the hollow spaces, adhesive force of the Styrofoam and the cap shell is improved, and the possibility that fingers are hurt in the hollow spaces is removed.
Description
Technical field
The present invention relates to a kind of crash helmet, particularly relate to a kind of crash helmet and manufacture craft of aluminium alloy cap shell.
Background technology
In the prior art, the cap shell part of common crash helmet is coated on Poly Foam (EPS) by one deck plastic tab (PC or PVC) to form, common plastics cap shell is not only due to the strength problem of material self, and because formation problems can only be plane effect on common plastics cap shell surface, can only rely on when resisting and be coated on interior Poly Foam, thus plastic tab often easily ftractures after the blow, not only have impact on Personal Safety, and also greatly reduce service life.
Summary of the invention
In view of this, main purpose of the present invention is the crash helmet and the manufacture craft that provide a kind of aluminium alloy cap shell, pass through the technical program, aluminium alloy cap shell is adopted to make crash helmet, and make full use of ductility and the thermal conductivity of aluminium alloy, along cap shell, longitudinally through arch form fin is set on cap shell surface, the inner edge place of each transmission of aluminium alloy is provided with bending bound edge, thus effectively raise the bulk strength of crash helmet, and improve the foaming effect of Poly Foam, stop the phenomenon of crash helmet face checking, thus make up the deficiencies in the prior art.
In order to achieve the above object, technical scheme of the present invention realizes like this.
A crash helmet manufacture craft for aluminium alloy cap shell, carries out according to the following steps.
A. make aluminium alloy cap shell, adopt aluminum alloy flake to be gone out the form of cap shell by stretching calendering technology straight forming, by punching and blanking and rolling, but flash removed and excess stock.
B. cap shell surface treatment, processes to obtain cap shell product through surperficial scrubbing, heat-tinting, polishing, plating etc., and coated with adhesive overleaf.
C. crash helmet global formation, is placed on aluminium alloy cap shell in foaming mould and carries out Poly Foam foaming, and aluminium alloy cap shell and Poly Foam connecting shaping are integrated.
A kind of crash helmet of aluminium alloy cap shell, include aluminium alloy cap shell, Poly Foam head capsule and transmission, described aluminium alloy cap shell is coated on Poly Foam head capsule, described transmission is arranged in the arc-shaped surface of aluminium alloy cap shell and Poly Foam head capsule, described aluminium alloy cap shell is suppressed by aluminum alloy materials and is formed, and in the middle part of aluminium alloy cap shell, both sides are provided with arch form fin along aluminium alloy cap shell is longitudinally through respectively.
The width of described arch form fin is 5-10mm, and arch form fin height of projection is 3-5mm.
On described aluminium alloy cap shell, transmission inner edge is respectively arranged with downward-sloping bending bound edge.
The angle of described bound edge and aluminium alloy cap shell tangential direction is 30 °-75 °.
Beneficial effect after employing technique scheme is: a kind of crash helmet of aluminium alloy cap shell and manufacture craft, pass through the technical program, aluminium alloy cap shell is adopted to make crash helmet, and make full use of ductility and the thermal conductivity of aluminium alloy, on aluminium alloy cap shell surface, through arch form fin is set, considerably increase the intensity of crash helmet, when being collided, aluminium alloy cap shell can not ftracture, ensure that the globality of crash helmet, Poly Foam can not crackedly come, aluminium alloy cap shell deforms after being clashed into simultaneously, also part energy can be absorbed, thus better protect user's head, and it is very cruel to substantially increase appearance aesthetic feeling, dazzle very much, the texture of aluminium alloy is that user brings brand-new experience, in transmission, bending bound edge is set, improve the adhesive force of Poly Foam and cap shell, eliminate the possibility that transmission injures finger, in addition, aluminium alloy cap shell breaches the bad problem of conventional plastic cap shell heat conduction, Poly Foam particle can be made more fully by heat foamable, reach the impact strength of designing requirement, shorten molding cycle simultaneously and also save steam energy consumption.
Accompanying drawing explanation
Fig. 1 is the top view of aluminium alloy cap shell in the present invention.
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
In figure, 1 aluminium alloy cap shell, 2 transmissions, 3 arch form fins, 4 bending bound edges.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment in the present invention is described in further detail.
The crash helmet manufacture craft of the aluminium alloy cap shell that the present invention relates to, carries out according to the following steps.
A. make aluminium alloy cap shell, adopt aluminum alloy flake to be gone out the form of cap shell by stretching calendering technology straight forming, by punching and blanking and rolling, but flash removed and excess stock.
B. cap shell surface treatment, processes to obtain cap shell product through surperficial scrubbing, heat-tinting, polishing, plating etc., and coated with adhesive overleaf.
C. crash helmet global formation, is placed on aluminium alloy cap shell in foaming mould and carries out Poly Foam foaming, and aluminium alloy cap shell and Poly Foam connecting shaping are integrated.
As depicted in figs. 1 and 2, the crash helmet of the aluminium alloy cap shell that the present invention relates to, include aluminium alloy cap shell 1, Poly Foam head capsule and transmission 2, described aluminium alloy cap shell 1 is coated on Poly Foam head capsule, described transmission 2 is arranged in the arc-shaped surface of aluminium alloy cap shell 1 and Poly Foam head capsule, described aluminium alloy cap shell 1 is suppressed by aluminum alloy materials and is formed, and in the middle part of aluminium alloy cap shell 1, both sides are provided with arch form fin 3 along aluminium alloy cap shell 1 is longitudinally through respectively.
