Problems solved by technology

Due to the increase of foam in this safety helmet, the material cost of the safety helmet has increased; and this kind of safety helmet is to fit the foam glue between the cap shell and the buffer lining first, and then make the foam glue The foamed material is formed by foaming, so that the foamed material is closely combined with the cap shell and the cushioning lining. Compared with the traditional safety helmet, the production is more complicated; The lining may still be deformed, resulting in a decrease in the cushioning capacity of the cushioning lining

Embodiment Construction

[0020] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0021] The invention discloses a safety helmet manufacturing process, which comprises the following steps:

[0022] Step 1. Cushion lining molding: put foam material in the cushion lining mold, then heat and pressurize the cushion lining mold, so that the foam material will foam in the cushion lining mold to form a cushion lining 1, then remove the buffer lining 1;

[0023] Step 2, safety helmet preform: the polymer fiber material pre-impregnated with resin is attached to the outer surface of the buffer liner, thereby obtaining the safety helmet preform composed of the buffer inner liner 1 and the polymer fiber material pre-impregnated with resin body;

[0024] Step 3. Helmet molding: Put the preform of the helmet into the helmet mold 3 and heat it for molding, so that the polymer fiber material pre-impregnat...

Abstract

The invention discloses a safety helmet manufacturing process, which comprises the following steps: Step I, forming a buffer liner; Step II, pre-forming a safety helmet; Step III, forming the safety helmet. According to the safety helmet manufacturing process, a helmet shell is directly formed on the buffer liner, so that the process is simple, and the helmet shell and the buffer liner can be combined tightly.

Description

technical field [0001] The invention relates to the field of safety helmets, in particular to a production process of safety helmets. Background technique [0002] Traditional safety helmets generally include a cap shell and a cushioning liner attached to the cap shell. When assembling, the cushioning liner is inserted into the cap shell and glue is applied between the cap shell and the cushioning liner, so that the The buffer liner is connected to the inner wall of the cap shell. Since the glue is difficult to fill the gap between the buffer liner and the inner wall of the cap shell, the combination of the buffer liner and the cap shell is not tight, and there will be a gap. This gap is encountered in traditional safety helmets. High-speed or high-pressure impacts will cause more serious injuries to the wearer due to secondary impacts; and the cushioning lining is hard inserted into the cap shell, and the cushioning lining may be deformed, resulting in a decrease in the cus...
