Description

Technical Field

[0001] The utility model relates to the technical field of seamless gas cylinder process equipment, in particular to a heat treatment tool for steel seamless gas cylinders. Background Art

[0002] Steel seamless gas cylinders have an increasing market share due to their advantages such as short manufacturing cycle, no welds and high pressure resistance, and have become an indispensable part of natural gas transportation equipment. At present, in terms of natural gas cylinder transportation methods, the trend is to expand the volume of a single gas cylinder to improve the volume-to-weight ratio and reduce the unit transportation cost. Compared with other gas cylinders such as wrapped cylinders, steel seamless gas cylinders are based on the material characteristics of steel. When expanding the volume of gas cylinders, the manufacturing process is more mature, the process is simpler, more competitive, and safer and more reliable. Large-volume steel seamless gas cylinders are currently mainly used for compressed natural gas transportation, and can also be used for the storage and transportation of various high-pressure gases such as hydrogen, helium, nitrogen, and argon. The application areas can cover natural gas, special gas transportation, gas stations, petrochemicals and other fields.

[0003] Since the storage medium of large-volume seamless steel gas cylinders is mostly high-pressure gas, its working pressure often reaches more than 20MPa. Therefore, how to ensure its excellent mechanical properties under such high pressure conditions? The overall mechanical properties of the seamless gas cylinder are changed by quenching and tempering. However, when the seamless steel gas cylinder is subjected to quenching and tempering heat treatment, once it is placed flat or tilted, the roundness and straightness of the seamless steel gas cylinder will deteriorate, affecting subsequent processing. Therefore, when the seamless steel gas cylinder is heat treated, it is usually placed vertically into the furnace.

[0004] In order to ensure that the seamless steel gas cylinders can be placed vertically into the furnace, positioning rings are currently used to place the seamless steel gas cylinders vertically in the furnace. However, there are no systematic regulations and requirements for the size of the positioning rings. Therefore, there is a large gap between some seamless steel gas cylinders and the positioning rings, resulting in poor positioning of the seamless steel gas cylinders. It is also easy for the seamless steel gas cylinders to be skewed, which affects the overall performance of the seamless steel gas cylinders after heat treatment. Utility Model Content

[0005] The utility model aims to provide a heat treatment tool for a seamless steel gas cylinder, which has an adjustment function and can adjust the gap between the seamless steel gas cylinder and a positioning ring, thereby improving the positioning effect of the seamless steel gas cylinder.

[0008] At least two axially arranged positioning rings are configured to clamp and fix the body of the seamless steel gas cylinder simultaneously;

[0009] A frame body, configured to connect all the positioning rings and define the positions of the positioning rings;

[0010] The adjusting mechanism is arranged on the positioning ring and is configured to adjust the ring opening size of the positioning ring so that the inner side of the positioning ring fits on the body of the steel seamless gas cylinder.

[0011] The utility model defines the position of each positioning ring by cooperating with a plurality of positioning rings through a frame, defines the position of a seamless steel gas cylinder through the positioning ring, and supports the seamless steel gas cylinder located in the positioning ring; secondly, each positioning ring has an adjustment mechanism for adjusting the ring size of the positioning ring, so that all positioning rings are arranged axially and clamp and fix the body of the seamless steel gas cylinder together. At the same time, the adjustment mechanism with an adjustment function can adjust the gap between the seamless steel gas cylinder and the positioning ring, so that the inner side of the positioning ring fits with the body of the seamless steel gas cylinder, thereby improving the positioning effect of the seamless steel gas cylinder.

[0013] The frame has at least two connecting rods, which correspond to all the positioning rings one by one. One end of the connecting rod is welded to the outer side of the positioning ring, and the other end of the connecting rod is connected to the other end of the adjacent connecting rod through a support rod, so that the two connecting rods and the support rod form a common support for all directional rings in the same direction.

[0014] Each connecting rod provided in the utility model corresponds to a positioning ring and is welded to the positioning ring, and then the upper and lower adjacent positioning rings are connected in series through the supporting rods through the connecting rods, so that all the positioning rings are located on a frame, and the frame supports all the positioning rings.

[0015] 3) A heat treatment tool for seamless steel gas cylinders according to 1), wherein:

[0016] The positioning ring has a fracture for installing the adjustment mechanism, one end of the fracture is a fixed end, and the other end is a movable end. The fixed end is provided with a deep groove along the ring line of the positioning ring, and the deep groove is used for the adjustment mechanism to extend into and be fixed in the deep groove.

[0017] The fracture designed in the utility model enables the ring wall of the positioning ring to have an opening, which facilitates the adjustment of the size of the positioning ring; the adjustment mechanism is designed at the fracture position, and the adjustment mechanism extends into different positions in the deep groove to facilitate the adjustment of the ring opening size of the positioning ring.

[0018] 4) A heat treatment tool for seamless steel gas cylinders according to 3), wherein:

[0023] When the inserting rod of the utility model is inserted into the deep groove, the end of the inserting rod first contacts the end of the abutment block toward the groove opening and is squeezed by the end. At this time, the operator encounters less resistance when inserting the inserting rod. When the operator continues to move the inserting rod toward the inside of the deep groove, the inserting rod is subjected to the friction force of all the raised balls, thereby further strengthening the resistance to moving the inserting rod. On the contrary, after the inserting rod is inserted into the deep groove, the resistance encountered when moving the inserting rod becomes the resistance to blocking the movement of the inserting rod. At the same time, the abutment block and the raised balls integrally protrude from the inner groove wall of the deep groove to squeeze and fix the inserting rod, thereby realizing the fixing operation of the inserting rod.
