Embodiment 1

[0031] Embodiment one is basically as attached figure 1 As shown: a fully wound gas storage cylinder, including an inner tank 11 and a lightweight shell 10 that is close to and fully covers the inner tank 11 . The lightweight casing 10 includes a winding layer and a photocurable resin layer coated on the outer surface of the winding layer. Wherein, the photocurable resin layer is not necessary, and when there is no photocurable resin layer, the lightweight housing 10 is the wrapping layer. Wherein, the liner 11 includes a tail plug end seal 21 on the left and a bottle mouth end seal 22 on the right.

[0032] A tail plug end 211 protruding to the left and passing through the lightweight shell 10 is welded at the center of the tail plug end head 21 . The tail plug end 211 is coaxial with the inner tank 11, and the tail plug end 211 has a connection port facing the outside. Through the connection port, the tail plug end 211 can be connected with other fixed structures, which i...

Embodiment 2

[0064] In this embodiment, the weight-to-volume ratio of the fully wound gas cylinder is greater than 0.4 and less than or equal to 0.5. In this embodiment, the weight-to-volume ratio of the fully wound gas cylinder is 0.44. Compared with the prior art, the fully wound gas cylinder of this embodiment is lightweight and has a smaller weight-to-capacity ratio, which is more conducive to the battery life of the fuel cell and the use of the fuel cell for vehicles.

[0065] When drawing, the punch is used to draw the blank at 80-120°C to form a cup-shaped semi-finished product. Between each drawing process, it is necessary to carry out the primary cup-shaped body, secondary cup-shaped body and tertiary cup-shaped body. Annealing treatment. During strong-rotation thinning, the strong-rotation equipment thins the cup-shaped semi-finished product at a speed of 40-72 mm per minute.

[0066] This program is derived from the project of the Ministry of Communications of China, which is ...

Embodiment 3

[0068] The difference between this embodiment and the first embodiment is that the fully wound gas storage cylinder is processed with a supporting base for supporting the fully wound gas storage cylinder during processing. As we all know, the transportation of high-pressure gas storage cylinders is a very critical link, which directly restricts the use of high-pressure gas storage cylinders. Therefore, when processing the fully wound gas storage cylinder, in order to better realize the movement and transportation, the matching processing forms a supporting seat that can be used together.

[0069] support such as figure 2 As shown, it includes a first card board 100 and a second card board 400 distributed up and down. The first pallet 100 and the second pallet 400 are connected by multiple (two in this embodiment) support bars b, and the support bar b and the first clamp 100 and the second clamp 400 are welded connect. The first clamping plate 100 has a "U"-shaped structure...

Abstract

The invention discloses a machining method of a fully-wound gas storage bottle and belongs to the technical field of high-pressure gas storage bottles. The machining method comprises the following steps that 1, an inner container is manufactured through a cold stamping and deep drawing manner; firstly, an aluminum blank is deeply drawn to form a cup-shaped semi-finished product, then the cup-shaped semi-finished product is strongly turned and thinned on strong turning equipment, and finally, the thinned ring-shaped semi-finished product is closed up on a closing-up machine to form the inner container; and 2, at least two layers of carbon fiber fully cover and are wound around the outer surface of the inner container in an intersecting manner to form winding layers, and the winding directions of two adjacent layers of carbon fiber are different. The gas storage bottle machined through the machining method solves the problem of uneven wining of the fiber, and the pressure-resisting ability of the gas storage bottle is better.

Description

technical field [0001] The invention relates to the technical field of high-pressure gas storage cylinders, in particular to a processing method for fully wound gas storage cylinders. Background technique [0002] A fuel cell is a battery that converts other energy into electrical energy by burning fuel gas. Fuel cell is a kind of clean energy, and it is also one of the effective ways to solve energy pollution when environmental protection is getting more and more attention. [0003] Fuel cells generally include gas cylinders for fuel gas storage. The battery life of the fuel cell is directly related to the gas storage capacity of the gas cylinder. Therefore, in order to increase the battery life of the fuel cell, it is often necessary to conduct research on improving the gas storage capacity of the gas cylinder. [0004] At present, in order to improve the gas storage capacity of the gas storage cylinder, the pressure resistance capacity of the entire gas storage cylinde...
