Hydraulic flexible sheet spreading device adopting concave mould for bulletproof helmet

Abstract

The invention relates to a hydraulic flexible sheet spreading device adopting a concave mould for a bulletproof helmet. The hydraulic flexible sheet spreading device comprises a rack, and an upper mould and a lower mould which are mounted in the rack, wherein an upper and lower mould closing guide deviation-rectifying device, a device for enabling the upper mould to rotate along with the lower mould and keeping, and a hot hydraulic system which is connected to the upper mould, are mounted on the upper mould; and an upper and lower mould closing safety locking device is mounted on the upper mould and the lower mould. The hydraulic flexible sheet spreading device is automatic in operation, each layer of sheets can be kept to be completely consistent to the inner part of a sheet spreading concave mould cavity of the lower mould in shape after being thermally, hydraulically and flexibly pressed, and the layers are bonded tightly without wrinkles and gas bubbles, so that a pre-pressing process of the bulletproof helmet can be cancelled, production efficiency is improved and product quality is guaranteed, and therefore, the hydraulic flexible sheet spreading device is suitable for beingpopularized and applied in the equipment fitting enterprises.

Description

technical field [0001] The invention relates to a thermohydraulic flexible laying device for a concave mold of a bulletproof helmet, which belongs to the technical field of production and processing machinery for bulletproof equipment. Background technique [0002] For the production of general-purpose and special warfare bulletproof helmets for armed police, when using the automatic bulletproof helmet automatic laying machine to lay sheets, since the upper mold is a metal mold with a fixed size, hot pressing after laying can only cause partial adhesion between the sheets , the bonding between the material pieces is not tight, not solid, and there are gaps, which are prone to air bubbles and wrinkles, and the overall anti-proof performance and strength will be reduced after the finished product. In order to avoid air bubbles and wrinkles, the pressing process must be Exhausting multiple times is time-consuming and labor-intensive, which affects work efficiency. Contents of...
