Problems solved by technology

[0005] The purpose of the present invention is to overcome the disadvantages of the prior art that when the pipe seat welded on the head of the gas storage cylinder is located on the same horizontal plane, the conventionally used standard pipe seat and the circular automatic welding method have poor application effect, and provide a gas storage cylinder seal Head, the design of the head of the gas storage cylinder in the present invention not only meets the requirements of the direction of the pipe seat, but also unifies the standard of the pipe seat, which facilitates welding; the design of the upsetting punching die reduces the two processes of upsetting and punching to One process reduces the production cost and ensures the size of the head well, ensuring the stability of the mass production of the head of the gas tank

Embodiment 1

[0032] combine figure 1 with figure 2 , and an introduction to the background technology. In this embodiment, in order to solve the problem that the air pipe of the gas storage tank adopts a hard pipe connection, the pipe seat 1 welded on the head 2 of the gas storage tank is required to be kept on the same level, so that the welding quality of the pipe seat 1 cannot be guaranteed by the conventional circular automatic welding method, and the commonly used The problem that the standard socket can no longer be used. designed as Figure 4 As shown in the head of a gas storage cylinder, the material thickness of the head 2 is 3mm, and the head 2 is provided with a boss 3, and the boss 3 is distributed on the circle centered on the highest point of the arc surface of the head 2 on, see image 3 In (b), in this embodiment, a total of 4 bosses 3 are arranged, and the intervals between the bosses 3 are equal to 90°. The distribution of the bosses 3 can also be designed according...

Embodiment 2

[0046] The head of a gas storage cylinder in this embodiment is basically the same as that of Embodiment 1, except that the radius of the arc surface of the first transition surface 31 in this embodiment close to the arc surface of the head 2 is 17 mm, and the punch 63 is assembled Eccentric distance L 1 is 4.5mm, the distance L between the side wall of the inclined surface stretching groove 621 and the outer wall of the convex and concave die 71 2 is 12mm; the arc surface radius R of the arc surface at the bottom of the side wall of the inclined plane stretching groove 621 1 is 17mm.

Embodiment 3

[0048] The head of a gas storage cylinder in this embodiment is basically the same as that of Embodiment 1, except that the radius of the arc surface of the first transition surface 31 in this embodiment close to the arc surface of the head 2 is 20mm, and the punch 63 is assembled Eccentric distance L 1 5.0mm, the distance L between the side wall of the inclined plane stretching groove 621 and the outer wall of the convex and concave die 71 2 is 13mm; the arc surface radius R of the arc surface at the bottom of the side wall of the inclined plane stretching groove 621 1 20mm.

[0049] The head of a gas storage cylinder described in Examples 1 to 3, the design of the head of the gas storage cylinder not only meets the requirements of the direction of the pipe seat, but also unifies the standard of the pipe seat and facilitates welding; the design structure of the upsetting punching die is simple , the two processes of upsetting and convex forming and punching are reduced to o...

Abstract

The invention discloses an air cylinder seal cap and belongs to the field of processing of air cylinders. The seal cap disclosed by the invention is provided with bosses distributed on a circumference with the apex of the cambered surface of the seal cap as the centre of a circle; each boss comprises a horizontal plane, a cambered transitional seal cap surface and a first transitional surface and a second transitional surface of the horizontal plane, and the apexes of the horizontal plane and cambered transitional seal cap surface of each boss are located on the same horizontal plane; the end, which is adjacent to the horizontal plane, of each first transitional surface is an inclined plane, and the end, which is adjacent to the cambered transitional seal cap surface, of each first transitional surface is a circular arc surface; the second transitional surfaces are cambered surfaces. According to the air cylinder seal cap design disclosed by the invention, the traditionally used standard tube holder is welded on a seal cap boss; as planar welding is adopted, the tube holder is small in deformation after being welded, and the horizontal size of the tube holder is better ensured, thus not only meeting the requirement on the direction of the tube holder, unifying the tube holder standard, facilitating the welding and saving the welding cost of the tube holder.

Description

technical field [0001] The invention relates to the technical field of gas storage tank processing, and more specifically, relates to the design of the head of a gas storage tank for automobiles. Background technique [0002] The air storage tank is a device for storing the compressed gas of the air compressor (air pump) in the automobile braking system. In the traditional technology, the vent tube of the air reservoir is connected by a hose, see figure 1 In (a) and (b), the direction of the tube base 1 is perpendicular to the tangent direction of the arc of the head 2. This connection method between the tube base 1 and the head 2 can facilitate the welding of the tube base 1 very well. [0003] However, with the continuous development of science and technology, the requirements for the appearance and quality of the gas storage tank are getting higher and higher. More and more air pipes of gas storage tanks are connected by hard pipes, and the way of hard pipe connection r...
