High-pressure hydrogen storage tank inner container forming device and process

Abstract

The invention relates to a high-pressure hydrogen storage tank inner container forming device and further relates to a high-pressure hydrogen storage tank inner container forming process adopting theforming device. The high-pressure hydrogen storage tank inner container forming device comprises a rack, a rotary frame, a forming mold and a drive device, wherein one end of the rotary frame is connected with the rack, and the other end of the rotary frame is connected with the forming mold; the drive device comprises a first drive mechanism and a second drive mechanism; the first drive mechanismcan drive the rotary frame to rotate; the rotary frame can drive the forming mold to rotate around the X axis; the second drive mechanism drives the forming mold to rotate around the Y axis; the forming mold comprises a mold body and a frame body; the mold body is installed on the frame body and provided with a plurality of sets of electric heating pipes; the mold body comprises a barrel with twoends being open, a first seal end and a second seal end; the first seal end and the second seal end are arranged at the two ends of the barrel and area connected with the two ends of the barrel in anopening and closing mode. The process is simple and can prepare seamless type dual-layer high-pressure hydrogen storage tank inner containers.

Description

technical field [0001] The invention relates to a high-pressure hydrogen storage tank liner forming equipment and a forming process. Background technique [0002] The inner liner of the current high-pressure hydrogen storage tank is generally made of aluminum, which is processed by the high-temperature shrinking head of the seamless aluminum tube, then heat-treated, and then drilled. Aluminum itself is prone to hydrogen embrittlement, has low pressure resistance, is heavier than resin liners, and has a complex production process. [0003] At present, Japan has an injection molding process to produce the liner of high-pressure hydrogen storage tanks. The liner is made of resin material. Because the resin material has the advantages of good barrier property, light weight, and long service life, it is very suitable for making liners of high-pressure hydrogen storage tanks. The current technology adopts split injection molding, and then glues the inner tank into one. There are ...

Aluminum itself is prone to hydrogen embrittlement, low pressure resistance, heavier than resin liner, and complex production process

[0003] At present, Japan has an injection molding process to produce the liner of high-pressure hydrogen storage tanks. The liner is made of resin material. Because the resin material has the advantages of good barrier property, light weight, and long service life, it is very suitable for making liners of high-pressure hydrogen storage tanks. The current technology adopts split injection molding, and then glues the inner tank into one. There is a butt joint gap on the inner tank, which is prone to cracking, affecting product quality and service life, and has low pressure resistance.
