Description

Technical Field

[0001] The invention belongs to the technical field of gas cylinder processing, and in particular relates to a double-cavity aluminum-magnesium alloy gas cylinder. Background Art

[0002] The air reservoir is a gas storage device in the automobile braking system; the air reservoir is used to store the gas compressed by the air compressor (air pump) and is used in automobile braking, whistle and other systems;

[0003] During the processing of the gas cylinder, multiple welding processes are required, in which a partition needs to be welded inside the cylinder body, so that the inside of the cylinder body is divided into two independent chambers, each chamber has its own corresponding automobile parts;

[0004] However, welding the partition in the middle of the cylinder is a very difficult operation, and the following two problems often exist in production: 1. Workers need to hold a welding gun and insert it into the cylinder for welding. Due to the narrow welding space, observation is difficult, and the quality of the weld is difficult to grasp; 2. Since the interior of the cylinder is a smooth structure, the partition lacks limiting measures during pre-positioning, making it impossible for workers to accurately grasp the fixed position of the partition and whether it is tilted, resulting in uneven welds and misaligned welding positions; Since the above two problems will affect the quality of the weld, it will eventually affect the barrier effect of the partition, resulting in cross-flow of high-pressure gas in the two chambers. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a double-chamber aluminum-magnesium alloy gas storage cylinder, and the specific technical solution is as follows:

[0007] The second chamber is provided with an assembly plate inside, the assembly plate is a hollow structure, and the assembly plate abuts against the other side of the inner retaining ring;

[0008] The centers of the partition and the assembly plate are penetrated by locking studs, and the outer ends of the locking studs are threadedly sleeved with nuts. The locking studs are used to clamp and fix the assembly plate and the partition on both sides of the inner retaining ring.

[0009] Furthermore, the inner convex height of the inner retaining ring is 1cm-2cm.

[0010] Furthermore, the outer diameter of the partition is the same as the outer diameter of the assembly plate, and the outer walls of the partition and the assembly plate are both covered with sealing rings, and the sealing rings are tightly fitted with the inner wall of the cylinder.

[0012] Furthermore, the assembly plate includes an inner ring body, reinforcement ribs and an outer ring body, the outer wall of the inner ring body is provided with reinforcement ribs distributed in a ring array, the outer ends of the reinforcement ribs are connected to the outer ring body, the inner ring body and the outer ring body are concentrically arranged, the outer ring body abuts against the side wall of the inner retaining ring, and the locking studs pass through the interior of the inner ring body.

[0013] A preparation method for preparing the above-mentioned double-chamber aluminum-magnesium alloy gas storage cylinder comprises the following steps:

[0014] S1. Cylinder preparation:

[0015] Convey the flat raw material plate between the upper and lower reels;

[0016] The upper and lower reels roll the raw material sheet into a cylinder. During the rolling process, the extrusion ring on the outer wall of the lower reel squeezes the corresponding portion of the sheet upward into the matching groove on the outer wall of the upper reel to form an inner retaining ring, which divides the interior of the cylinder into a first chamber and a second chamber.

[0017] S2. Install the partition components:

[0018] Insert the partition into the first chamber, the sealing ring on the outer wall of the partition is tightly fitted with the inner wall of the cylinder, and the partition stops moving when it hits one side of the inner stop ring;

[0019] Insert the assembly plate into the second chamber, the sealing ring on the outer wall of the assembly plate is tightly fitted with the inner wall of the cylinder, and the assembly plate stops moving when it hits the other side of the inner stop ring;

[0020] Pass the locking stud through the center of the assembly plate and the partition in turn, and let the locking stud extend out of the partition. Then put the rubber ring on the extended part of the locking stud, and finally tighten the nut. At this time, the assembly plate and the partition are firmly and flatly clamped and fixed on both sides of the inner retaining ring, and the partition separates the first chamber and the second chamber into two independent chambers.

The partition 3 is sealed against one side of the inner retaining ring 11. The partition 3 is used to separate the first chamber 12 and the second chamber 13 into two independent chambers.

[0036] The second chamber 13 is internally provided with a mounting plate 4, which is a hollow structure and contacts the other side of the inner retaining ring 11; the hollow structure is used to ensure that the two sides of the mounting plate 4 are connected, and the mounting plate 4 is mainly used as a positioning auxiliary component of the partition 3, and does not play the role of blocking the chamber;

[0037] The centers of the partition plate 3 and the assembly plate 4 are penetrated by locking studs 5, and the outer ends of the locking studs 5 are threadedly fitted with nuts 51. The locking studs 5 are used to clamp and fix the assembly plate 4 and the partition plate 3 on both sides of the inner retaining ring 11; the assembly plate 4 and the partition plate 3 can be quickly and easily assembled into one through the locking studs 5. At the same time, when the locking studs 5 are rotated, the assembly plate 4 and the partition plate 3 can also be leveled and corrected, so that the assembly plate 4 and the partition plate 3 can be more flush and in contact with the inner retaining ring 11.

[0038] As an improvement of the above technical solution, the inner convex height of the inner retaining ring 11 is 1cm-2cm; it is designed to be 1-2cm to ensure that the inner retaining ring 11 can provide reverse support and resistance without occupying too much space, thereby ensuring that the air storage space of the cylinder is large enough.

[0042] A method for preparing a double-cavity aluminum-magnesium alloy gas storage cylinder, the method comprising the following steps:

[0043] S1. Preparation of cylinder 1:

[0044] The flat raw material plate is conveyed between the upper reel 7 and the lower reel 8;

[0045] The upper reel 7 and the lower reel 8 roll the raw material plate into a cylinder 1. During the rolling process, the extrusion ring 81 on the outer wall of the lower reel 8 squeezes the portion of the plate it faces upward into the matching groove 71 on the outer wall of the upper reel 7, thereby forming an inner retaining ring 11. The inner retaining ring 11 divides the interior of the cylinder 1 into a first chamber 12 and a second chamber 13. This step is used to roll the inner retaining ring 11 with an inner convex shape, and the processing is simple. The extrusion ring 81 is arranged opposite to the matching groove 71, and the extrusion ring 81 is vertically arranged on the outer wall of the lower reel 8.

[0046] S2. Install the partition components:

[0047] Insert the partition 3 into the first chamber 12, and the sealing ring 6 on the outer wall of the partition 3 is tightly fitted with the inner wall of the cylinder 1. When the partition 3 contacts one side of the inner stop ring 11, the action stops. This step is used to first install the partition 3 on one side to the specified position. When inserting the partition 3, the finger passes through the installation hole 31 in the center of the partition 3. When the partition 3 is inserted to the specified position, the finger leaves the installation hole 31. The installation hole 31 can facilitate the worker to move and assemble the partition 3 in this step, and can have a force application point, and it is also convenient for the hand to separate from the partition 3.

[0048] Insert the assembly plate 4 into the second chamber 13, and the sealing ring 6 on the outer wall of the assembly plate 4 is tightly fitted with the inner wall of the cylinder 1. When the assembly plate 4 hits the other side of the inner stop ring 11, the action stops; when inserting the assembly plate 4, the finger passes through the inner ring body 41 in the center of the assembly plate 4, and when the assembly plate 4 is inserted to the specified position, the finger leaves the inner ring body 41; the inner ring body 41 can facilitate the worker to move the assembly partition 3 at this step, and can have a force application point, and it is also convenient for the hand to separate from the assembly plate 4;

[0049] The locking stud 5 is passed through the center of the assembly plate 4 and the partition 3 in sequence, and the locking stud 5 is extended outward from the partition 3. Then the rubber ring is put on the extended part of the locking stud 5, and finally the nut 51 is tightened. At this time, the assembly plate 4 and the partition 3 are firmly and evenly clamped and fixed on both sides of the inner retaining ring 11, and the partition 3 blocks the first chamber 12 and the second chamber 13 into two independent chambers; this step is used to assemble the assembly plate 4 and the partition 3 into one body through the locking stud 5, so that the assembly plate 4 and the partition 3 are stably clamped and fixed on both sides of the inner retaining ring 11;

[0050] During implementation, the locking stud 5 passes through the inner ring body 41 of the assembly plate 4 and the mounting hole 31 of the partition 3 in sequence, and finally the locking stud 5 will partially protrude from the mounting hole 31, a rubber ring is put on the protruding part, and the nut 51 is screwed on. While twisting, the assembly plate 4 and the partition 3 are further brought closer, and the two further press the inner retaining ring 11. While pressing, the assembly plate 4 and the partition 3 will also be reversely supported by the inner retaining ring 11, so that the assembly plate 4 and the partition 3 are corrected to a flat state, thereby realizing calibration while tightening. While rotating, the nut 51 will further compress the sealing ring. After tightening, the assembly plate 4 and the partition 3 are assembled as a whole, and the partition 3 blocks the cylinder into two chambers that are not connected to each other;

[0051] S3. Weld the end covers at both ends.
