Description

Technical Field

[0001] This utility model relates to the field of titanium alloy thin-walled cylinder technology, and in particular to an auxiliary device for heat treatment of titanium and titanium alloy thin-walled cylinders. Background Technology

[0002] Titanium and titanium alloys possess an excellent strength-to-weight ratio; their density is approximately 60% that of steel, yet their strength is comparable to high-strength steel. In the aerospace industry, thin-walled cylindrical structures are widely used in critical components such as aircraft engine parts, landing gear, and rocket fuel tanks. For example, the use of titanium and titanium alloy thin-walled cylindrical structures in aircraft engine compressor blades and combustion chambers reduces the aircraft's weight while meeting performance requirements under extreme conditions such as high temperature, high pressure, and high speed, thereby improving fuel efficiency and flight performance.

[0003] In the current technology, there is an auxiliary device for heat treatment of thin-walled cylinders of titanium and titanium alloys. During the loading, unloading and heat treatment processes, the thin-walled cylinders are prone to deformation, resulting in failure to meet the required dimensions and scrapping. The small loading volume requires multiple loadings, leading to low heat treatment production efficiency, high electricity production costs, inconvenient loading and unloading operations, long loading and unloading times, and rapid cooling of the furnace resistance band, which reduces the service life of the electric furnace. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where thin-walled cylinders are easily deformed during the loading and unloading process and heat treatment, resulting in non-compliance with the external dimensions and scrapping; small loading quantities require multiple loadings, leading to low heat treatment production efficiency, high electricity production costs, inconvenient and time-consuming loading and unloading operations, and rapid cooling of the furnace resistance, which reduces the service life of the electric furnace. Therefore, this invention proposes an auxiliary device for the heat treatment of titanium and titanium alloy thin-walled cylinders.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary device for heat treatment of titanium and titanium alloy thin-walled cylinders, comprising a base, a rectangular slot formed on the outer wall of the base, a bracket welded to the top of the base, a plurality of first limiting posts inserted into the bracket, support plates fixed on both sides of the top of the bracket, a plurality of second limiting posts inserted into each of the two support plates, the first limiting posts and the second limiting posts being staggered, and a titanium cylinder placed at the top of the base, the titanium cylinder being positioned in the gap between the first limiting posts and the second limiting posts.

[0006] Preferably, a first stud is fixed to one end of the first limiting post, a first nut is threaded to the end of the first stud located outside the bracket, and a first baffle is fixed to the end of the first limiting post away from the first stud.

[0007] Preferably, a second stud is fixed to one end of the second limiting post, a second nut is threaded to the end of the second stud located outside the support plate, and a second baffle is fixed to the end of the second limiting post away from the second stud.

[0008] Preferably, the bracket has multiple first limiting holes that match the first limiting post, and both support plates have multiple second limiting holes that match the second limiting post.

[0009] Preferably, there are multiple rectangular slots, and the rectangular slots are evenly distributed at the four ends of the base.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] In this invention, the base and rectangular slot facilitate the entry and exit of forklift forks, allowing the heat treatment auxiliary device to be lifted and lowered safely. Multiple first and second limiting posts, arranged in a grid pattern, allow titanium cylinders to be placed between each grid gap. This enables simultaneous heat treatment of multiple titanium cylinders, enhancing practicality. This device allows for the heat treatment of multiple titanium cylinders at once, improving efficiency and production capacity while reducing costs. The titanium cylinders are also less prone to deformation. The processed product still meets the product quality requirements. Forklift-assisted loading and unloading are simple to operate, enabling rapid loading and unloading while ensuring lifting safety. It also helps extend the service life of the electric furnace resistance band. Since the titanium cylinder is located in the grid-like space formed between the first and second limiting posts, if the titanium cylinder tilts during loading, it will quickly and automatically return to a vertical position relative to the base under the limiting of the first and second limiting posts and the gravity of the titanium cylinder itself. The heat treatment auxiliary device has a simple structure, is easy to manufacture, has low manufacturing cost, and is easy to maintain. Attached Figure Description

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1, as Figure 1-4 As shown, this utility model provides an auxiliary device for heat treatment of titanium and titanium alloy thin-walled cylinders, including a base 1. A rectangular slot 2 is provided on the outer wall of the base 1. A bracket 3 is welded to the top of the base 1. Multiple first limiting posts 4 are inserted into the bracket 3. Support plates 9 are fixed on both sides of the top of the bracket 3. Multiple second limiting posts 11 are inserted into each of the two support plates 9. The first limiting posts 4 and the second limiting posts 11 are staggered. A titanium cylinder 15 is placed at the top of the base 1. The titanium cylinder 15 is located in the gap between the first limiting posts 4 and the second limiting posts 11.

[0020] The overall effect of Embodiment 1 is that, through the setting of the base 1 and the rectangular slot 2, it is convenient for the forklift fork to enter and exit, lift and lower the heat treatment auxiliary device, and ensure the lifting safety. Through the setting of multiple first limiting posts 4 and second limiting posts 11, and the first limiting posts 4 and second limiting posts 11 are staggered and distributed in a grid shape, titanium cylinders 15 can be placed in each grid gap. During subsequent heat treatment, multiple titanium cylinders 15 can be heat treated at the same time, which makes it more practical.

[0021] Example 2, as Figure 1-4As shown, a first stud 5 is fixed to one end of the first limiting post 4, and a first nut 6 is threaded to the end of the first stud 5 located outside the bracket 3. A first baffle 7 is fixed to the end of the first limiting post 4 away from the first stud 5. A second stud 12 is fixed to one end of the second limiting post 11, and a second nut 13 is threaded to the end of the second stud 12 located outside the support plate 9. A second baffle 14 is fixed to the end of the second limiting post 11 away from the second stud 12. A plurality of first limiting holes 8 matching the first limiting post 4 are opened in the bracket 3. A plurality of second limiting holes 10 matching the second limiting post 11 are opened in both support plates 9. There are multiple rectangular slots 2, and the rectangular slots 2 are evenly distributed at the four ends of the base 1.

[0022] The effect achieved by the entire embodiment 2 is that, by setting the first limiting hole 8 and the second limiting hole 10, the first limiting post 4 and the second limiting post 11 can be inserted into different first limiting holes 8 and the second limiting hole 10 according to actual needs, and then the first nut 6 and the second nut 13 are screwed on the first stud 5 and the second stud 12, thereby limiting the position of the first limiting post 4 and the second limiting post 11, thereby adjusting the size of the gap in the grid, making it more practical.

[0023] Working principle: When using this device, before heat treatment, place the titanium cylinder 15 into the grid-like gap formed by the first limiting post 4 and the second limiting post 11, ensuring that the titanium cylinder 15 is placed vertically with the base 1 and maintains a certain distance. Adjust the spacing of the two forklift forks in advance, quickly connect and insert into the two rectangular slots 2 on one side of the base 1. After confirming safety, lift the heat treatment auxiliary device and the titanium cylinder 15 together to the same height as the furnace bottom, lift the furnace door, install it on the refractory bricks at the bottom of the furnace, remove the forklift forks, lower the furnace door, and press it down. Perform heat treatment according to the established heat treatment procedure. After heat treatment, lift the furnace door, adjust the forklift spacing in advance, move the forklift forward, insert it into the rectangular slot 2 opened on the side of the base hole 1, and take out the heat treatment auxiliary device and the titanium cylinder 15 together. Remove the titanium cylinder 15 from the heat treatment auxiliary device and let it air cool.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
