Manufacturing method and application of power safety helmet

Abstract

The invention discloses a manufacturing method and application of a power safety helmet. The manufacturing method is characterized by comprising the following steps of adhering and compounding a plurality of foam aluminum plates to form a foam aluminum middle core; shaping and processing the foam aluminum middle core by a mechanical processing method, so as to obtain a foam aluminum safety helmetcasing; drilling a hole in the foam aluminum safety helmet casing; using a foam aluminum safety helmet as a basic fie, drying the surface of the foam aluminum safety helmet, manufacturing a resin outer casing and a resin inner casing which are respectively matched with an outer edge and an inner cavity of the foam aluminum safety helmet, using the foam aluminum safety helmet as a middle interlayer, and adhering and compounding the resin outer casing, the resin inner casing and the middle interlayer, so as to complete the manufacturing of a main body. The manufacturing method has the advantagesthat the design technology of compounding the foam aluminum middle core and the resin is adopted, the weight is light, the strength is high, the excellent anti-impact damping property is realized, and the life safety of operators at the site can be furthest ensured.

Description

technical field [0001] The invention relates to a manufacturing method and application of an electric safety helmet. Background technique [0002] The safety helmet is a shallow dome hat made of steel or similar materials worn to protect the top of the head, and it is a protective product to prevent impact objects from hurting the head. When the worker's head is impacted by falling objects, a qualified safety helmet can decompose the impact force to the entire area of ​​the skull in an instant through the cap shell and cap lining, and then use the elastic deformation and plasticity of the cushioning structure of each part to The deformation and allowable structural damage absorb most of the impact force, reducing the final impact force on the head of the personnel to below 4900N, thereby protecting the head of the operator. [0003] At present, the materials used in the manufacture of safety helmet shells in China mainly include ABS (combined with acrylonitrile, J-ene and p...

AI Technical Summary

Problems solved by technology

[0004] Compared with helmets made of other materials, FRP helmets generally have significant advantages such as high strength, good electrical properties, and good corrosion resistance, but they also have low elastic modulus, easy deformation, poor long-term temperature resistance, and low interlayer shear strength. and disadvantages of easy aging

Under the action of ultraviolet rays, wind, sand, rain and snow, chemical media, mechanical stress, etc., it is easy to cause performance degradation and even endanger the life safety of operators.
