Embodiment 1

[0032] combine figure 1 and 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] An upsetting and convex punching die for the head of an air storage tank in this embodiment is basically the same as in Embodiment 1, except that the radius of the arc surface of the first transition surface 31 in this embodiment is 17 mm close to the arc surface of the head 2 , the punch 63 assembly 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] An upsetting and convex punching die for the head of an air storage tank in this embodiment is basically the same as in Embodiment 1, except that the radius of the arc surface of the first transition surface 31 in this embodiment is 20 mm close to the arc surface of the head 2 , the punch 63 assembly 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] An upsetting and convex punching die for the head of an air storage cylinder described in Examples 1 to 3, the design of the head of the air storage cylinder not only meets the requirements for the direction of the pipe seat, but also unifies the standard of the pipe seat, which facilitates welding; The design structure of the mold is simple, and the two processes of ...

Abstract

The invention discloses an air cylinder end enclosure upsetting punching die, and belongs to the technical field of processing of air cylinders. Bosses are arranged on an end enclosure and distributed on a circumference taking the highest point of the end enclosure cambered surface as a circle center, the highest point of the end enclosure cambered surface is positioned in a same horizontal plane with the horizontal plane of the bosses; a punch of the upsetting punching die is fixedly connected to an upper die plate by an upper padding plate, the punch fixing plate is simultaneously connected to a female die by a rectangular spring, and the lower part of the female die is provided with a slope stretching groove; the punch is fixedly connected to the punch fixing plate; the punch is fixedly connected to the punch fixing plate, and the punch penetrates through the punch fixing plate and the female die; a positioning block is movably connected to a lower die plate to limit a punch-die fixing plate; one end of the punch-die fixing plate is abutted against a punch-die washer while the other end of punch-die penetrates through a through hole formed in the punch-die fixing plate. According to the air cylinder end enclosure upsetting punching die, the design of the end enclosure meet the requirements on the direction of a tube base, thus being convenient to weld; due to the design of the upsetting punching die, two process of upsetting molding and punching are reduced to be one process, and stability in bulk production of the air cylinder end enclosures is ensured.

Description

technical field [0001] The invention relates to the technical field of gas storage tank processing, and more specifically relates to a design of an automobile gas storage tank head and an upsetting and convex punching die for the gas storage tank head. 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 conne...
