A gas tank head

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 air storage cylinder processing, and more specifically, to the design of a gas storage cylinder head for automobiles. Background technique [0002] The air reservoir is a device for storing compressed air by an air compressor (air pump) in the automobile brake system. In the traditional technology, the vent pipe of the air reservoir is connected by a hose, see figure 1 In (a) and (b), the direction of the socket 1 is perpendicular to the tangential direction of the arc of the head 2. This connection method of the socket 1 and the head 2 can facilitate the welding of the socket 1 very well. [0003] However, with the continuous development of science and technology, the requirements for the appearance and quality of the gas storage cylinder are getting higher and higher. More and more vent pipes of the gas storage cylinder are connected by hard pipes, and the use of hard pipe connection requires that the pipe so...

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
