Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of manufacturing methods of U-shaped slag-hooking tools used in front of blast furnaces, and specifically relates to a device for manufacturing U-shaped slag-hooking tools. Background Technique
[0002] In industries such as metallurgy, casting, and machining, professional tools are needed for scenarios such as cleaning residues on the surfaces of molds and castings or removing welding spatter. Due to its unique shape and design, the U-shaped slag-hooking tool can operate in narrow spaces, especially suitable for cleaning residues in hard-to-reach corners or gaps. During the use of this tool, it needs to have good rigidity, sufficient strength, and an appropriate curvature radius to ensure the safety and effectiveness of the operation.
[0003] There are currently two methods for manufacturing U-shaped slag-hooking tools used in front of blast furnaces.
[0004] The first method is to insert an oxygen pipe into high-temperature molten iron. After being softened by the erosion of the high-temperature molten iron, it is bent into a U shape.
[0005] The second method is to randomly insert the oxygen pipe into a place with holes at the production site, and then bend it by exerting force with both hands held high.
[0006] The first manufacturing method has an extremely high safety risk coefficient. When the oxygen pipe is inserted into high-temperature molten iron, since it is a hollow pipe, in the case of water or moisture at the insertion end, it will cause the oxygen pipe to explode. The high-temperature molten iron sprays out at high speed through the hollow structure of the oxygen pipe, resulting in high-temperature burns to the operator and posing a great threat to the safety of surrounding workers. Moreover, the U-shaped tool produced has a greatly reduced durability due to high-temperature erosion.
[0007] The second method causes great damage to the production site environment and also causes impact injuries to the personnel passing by at the site. When exerting force by holding the oxygen pipe tightly with both hands and applying the body weight, the oxygen pipe may bend excessively and come out of the hole, and the operator loses support and falls.
[0008] Therefore, there is an urgent need to design a device for manufacturing U-shaped slag-hooking tools to solve the problems of high risk, low efficiency, and potential safety hazards in the existing manufacturing methods. Content of the Utility Model
[0009] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a device for manufacturing U-shaped slag-hooking tools.
[0010] The technical solution adopted by the present utility model to solve its technical problems is: a device for manufacturing a U-shaped slag-hooking tool, including an operation table, a semi-circular plate, and an operation handle. A pipe bracket is provided on the operation table, and an oxygen pipe is placed on the pipe bracket. The oxygen pipe penetrates into an annular pipe. The lower part of the semi-circular plate is connected to the annular pipe. A pin shaft is provided in the middle of the semi-circular plate, and the semi-circular plate is rotatably connected to a triangular support frame through the pin shaft.
[0011] Specifically, the operation table is an operation plane, and a pipe bracket and a triangular support frame are provided on the operation table.
[0012] Specifically, the triangular support frame is arranged at the front end of the operation table. The upper part of the triangular support frame is fixedly connected to the pin shaft, and a shaft sleeve is sleeved on the pin shaft. The shaft sleeve is fixedly connected to the semi-circular plate and the operation handle.
[0013] Specifically, the semi-circular plate is a semi-circular steel plate, and the annular pipe is welded to the lower part of the semi-circular plate.
[0014] Specifically, the front part of the oxygen pipe passes through and is clamped in the annular pipe.
[0015] Specifically, the operation handle is a long round rod, and the operation handle is used to operate the semi-circular plate and the annular pipe to bend the oxygen pipe.
[0016] The present utility model has the following beneficial effects:
[0017] The device for manufacturing a U-shaped slag-hooking tool designed by the present utility model provides a safe and non-destructive slag-hooking tool. By innovating the tool manufacturing method, the durability of the tool and the safety of the manufacturing process are improved, and the service life of the tool is extended. At the same time, the ergonomic design of the handle part makes the operator hold it comfortably.

[0022] Embodiment 1:
[0023] As Figure 1 shown, a device for manufacturing a U-shaped slag-hooking tool includes an operating table 1, a semi-circular plate 2, and an operating handle 2.5. A pipe bracket 1.1 is provided on the operating table 1. The rear end of an oxygen pipe 3 is placed on the pipe bracket 1.1. The front section of the oxygen pipe 3 is connected to the semi-circular plate 2 through an annular pipe 2.1. The lower part of the semi-circular plate 2 is connected to the annular pipe 2.1.

[0024] When in use, place the operating table 1 on a flat surface. The operating table 1 is used to operate the oxygen pipe 3. Insert the front section of the oxygen pipe 3 into the annular pipe 2.1. The rear end of the oxygen pipe 3 is supported on the pipe bracket 1.1. The annular pipe 2.1 is used to fix the front section of the oxygen pipe 3. The pipe bracket 1.1 is used to place the rear end of the oxygen pipe 3. The upper part of the annular pipe 2.1 is welded to the semi-circular plate 2. The semi-circular plate 2 is made of steel material. The semi-circular plate 2 is used to press the oxygen pipe 3 into the required shape. The semi-circular plate 2 is connected to two triangular support plates 2.4 through a bushing 2.3. The triangular support plates 2.4 are used to support the semi-circular plate 2 to form a movable structure. The triangular support plates 2.4 are also used for protection.
