Abstract
Description
Technical Field
[0001] The utility model relates to the field of opening tools, and particularly relates to a simple subcontracting opening tool. Background Art
[0002] In industrial production processes such as iron and steel smelting and casting, structures such as magnesium injection nozzles play an important role. However, as production progresses, high-temperature substances such as molten iron and slag may accumulate around the magnesium injection nozzle, causing the magnesium injection nozzle to become blocked. This not only affects production efficiency but may also damage production equipment. Therefore, an efficient and reliable tool is needed to unclog the magnesium injection nozzle to ensure the smooth progress of the production process.
[0003] Currently, common unclogging methods in industrial production include manual unclogging, mechanical unclogging, etc. Manual unclogging has a high labor intensity, low efficiency, and is prone to causing injuries such as scalds to operators. Mechanical unclogging of magnesium injection nozzles usually uses high-pressure water jet equipment, which generates high-pressure water flow to wash the magnesium injection nozzle. Although the unclogging efficiency is high, the equipment cost is high, the operation difficulty is large, and professional personnel are required for operation. Content of the Utility Model
[0004] The utility model provides a simple subcontracting opening tool to solve the technical problems of high cost and large operation difficulty in the prior art.
[0005] To solve the above problems, the simple subcontracting opening tool provided by the utility model adopts the following technical scheme: It includes a mounting head, a limiting block, and a poking rod. A pulling column is arranged on the outer wall of the poking rod. The central axes of the mounting head, the limiting block, the poking rod, and the pulling column coincide with each other, and there is a gap between the pulling column and the limiting block.
[0006] Furthermore, the mounting head, the limiting block, the poking rod, and the pulling column are all made of heat-resistant steel.
[0007] Furthermore, the outer diameter of the pulling column is L1, the diameter of the limiting block is L2, the diameter of the mounting head is L3, and the diameter of the poking rod is L4, where L1 > L2 > L3 > L4.
[0008] Furthermore, the mounting head, the limiting block, and the poking rod are integrally formed by turning.
[0009] Furthermore, the pulling column is welded to the outer wall of the poking rod.
[0010] Furthermore, the mounting head, the limiting block, and the poking rod are all cylindrical structures.
[0011] Furthermore, a guiding part is arranged at one end of the mounting head away from the poking rod, and the diameter of the guiding part gradually decreases along the side away from the poking rod.
[0012] The beneficial effects of the simple subcontracting opening tool provided by the present utility model are as follows:
[0013] 1. This tool can quickly penetrate the molten iron layer, achieve rapid dredging of the magnesium injection port, is simple to operate, has a low manufacturing cost, and can effectively improve work efficiency;
[0014] 2. The poking rod is aligned with the magnesium injection port for pneumatic impact, and the pulling column is driven into the magnesium injection port and expands when heated. By expanding due to heat, the position of the poking rod in the magnesium injection port can be maintained, which can effectively prevent equipment damage or deformation of the magnesium injection port caused by excessive insertion of the poking rod, and there is a certain gap with the limit block. When needed, it can provide additional pulling force or pushing force to help the poking rod better penetrate the molten iron layer, with stronger practicability. Moreover, it can effectively prevent molten iron from spraying out when hitting the magnesium injection port and causing injury to the staff, with higher safety. Description of the Drawings

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Those skilled in the art should know that the following described embodiments are a part of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.
[0020] The number of any element in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning.
[0021] Next, with reference to several representative embodiments of the present utility model, the principles and spirit of the present utility model will be elaborated in detail.
[0022] The simple subcontracting opening tool provided by the present utility model, as Figure 1As shown, it includes a mounting head 1, a limiting block 2, and a poking rod 3. A pulling column 4 is provided on the outer wall of the poking rod 3. The central axes of the mounting head 1, the limiting block 2, the poking rod 3, and the pulling column 4 coincide with each other, and there is a gap between the pulling column 4 and the limiting block 2.
[0023] In this embodiment, the mounting head 1 is the part where the tool is connected to a pneumatic pick or other power source; the main function of the limiting block 2 is to limit the mounting position of the mounting head 1 on the power source; the poking rod 3 is used to penetrate the molten iron layer and dredge the magnesium injection port. After the poking rod 3 penetrates the molten iron layer, the pulling column 4 can further extend into the magnesium injection port, and maintain the position of the poking rod 3 in the magnesium injection port by thermal expansion, which can effectively prevent equipment damage or deformation of the magnesium injection port caused by excessive insertion of the poking rod 3, and can provide additional pulling or pushing force when needed to help the poking rod 3 better penetrate the molten iron layer, with stronger practicability, and can prevent molten iron from spraying out when hitting the magnesium injection port and causing injury to the staff, with higher safety.
[0024] In this embodiment, the setting of the gap can ensure that the pulling column 4 has enough space to expand when heated, avoiding jamming or damage to the tool.
[0025] It should be noted that the width of the gap between the pulling column 4 and the limiting block 2 can be adjusted according to actual usage requirements, and it is necessary to avoid excessive gap resulting in the pulling column 4 shaking or deviating from the central axis during the striking process.
[0026] In this embodiment, the mounting head 1, the limiting block 2, the poking rod 3, and the pulling column 4 are all made of heat-resistant steel, which can maintain relatively high mechanical strength at high temperatures. Even in the face of the impact and erosion of high-temperature molten iron, the tool can maintain its structural integrity and functionality. At the same time, a dense oxide film can be formed on the surface of the heat-resistant steel to prevent oxygen from further eroding the interior of the material. In addition, when the heat-resistant steel undergoes temperature changes, its size and shape change relatively little, which helps to maintain the accuracy and stability of the tool during the striking process.
[0027] In this embodiment, the mounting head 1, the limiting block 2, and the poking rod are integrally formed by turning, which can effectively enhance the integrity and structural strength of the tool. And because the mounting head 1, the limiting block 2, and the poking rod 3 are integrally formed by turning, their connection is more firm, which can effectively reduce the risk of failure caused by loosening or separation between components. In this embodiment, the pulling column 4 is welded to the outer wall of the poking rod 3 to ensure that the pulling column 4 is firmly fixed on the poking rod 3 and maintains a stable position during the striking process.
[0028] In this embodiment, the tool is heat-treated after being processed and formed to ensure that the tool obtains the best mechanical properties in the final form, which can enhance the hardness and toughness of the tool, make it better adapt to high-temperature and impact environments, resist high temperatures without deformation, and ensure that the poking rod 3 can smoothly penetrate the molten iron layer.
[0029] In this embodiment, the outer diameter of the pulling column 4 is L1, the diameter of the limiting block 2 is L2, the diameter of the installation head 1 is L3, and the diameter of the poking stick 3 is L4, L1>L2>L3>L4. In this embodiment, the pulling column 4, as an extension of the poking stick 3, needs a sufficient outer diameter to ensure that it can be firmly fixed on the poking stick 3 and withstand the impact of blows and high-temperature molten iron. The larger outer diameter provides a larger contact area and stronger structural support, and the larger outer diameter helps to reduce the impact of thermal expansion on the size; the limiting block 2 is used to limit the installation position of the installation head 1 on the power source, and the diameter of the limiting block 2 is larger than the diameter of the installation head 1; the poking stick 3 is the main part of the tool, which is responsible for penetrating the molten iron layer and unblocking the magnesium spraying port. Since the poking stick 3 needs to be inserted into the magnesium spraying port, its diameter should be as small as possible to reduce the contact area with the molten iron and reduce heat transfer. At the same time, the smaller diameter also helps to improve the rigidity and flexibility of the poking stick 3, making it easier to penetrate the molten iron layer.
[0030] In this embodiment, the mounting head 1, the limit block 2, and the poking stick 3 are all cylindrical structures, so that they can evenly distribute stress when subjected to force, which can effectively improve the strength and stability of the tool. The cylindrical structure is also easy to process and install, and can ensure that the connection between the components is tight and reliable.
[0031] It should be noted that the end of the poking rod 3 away from the mounting head 1 is a plane, which can better push the iron in the magnesium spraying port out.
[0032] In this embodiment, a guide portion 11 is provided at one end of the installation head 1 away from the poking stick 3, and the diameter of the guide portion 11 decreases step by step along the side away from the poking stick 3, so that the tool can more easily find the correct position and direction when inserted into a pneumatic pick or other power source connection.
[0033] The working principle of the simple subcontract opening tool provided by the utility model is as follows: the tool is connected to a pneumatic pick or other power source through an installation head 1, and the force generated by the power source is transmitted to the poking stick 3 through the installation head 1, and the poking stick 3 is aimed at the magnesium spraying port for pneumatic striking to penetrate the molten iron layer to form a channel. After the poking stick 3 penetrates the molten iron layer, the pulling column 4 can further extend into the magnesium spraying port, and maintain the position of the poking stick 3 in the magnesium spraying port by thermal expansion, which can effectively prevent damage to the equipment or deformation of the magnesium spraying port caused by excessive insertion of the poking stick 3, and can provide additional pulling force or pushing force when needed to help the poking stick 3 better penetrate the molten iron layer, so it is more practical, can prevent injuries to workers caused by molten iron spraying when striking the magnesium spraying port, and has higher safety.
[0034] Based on the above description in this specification, those skilled in the art can also understand the terms used as follows. For example, terms indicating orientation or positional relationships such as "upper", "lower", "front", "rear", "left", "right", "width", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings of this specification. They are only for the purpose of facilitating the description of the solutions of the present utility model and simplifying the description, rather than explicitly or implicitly indicating that the devices or elements involved must have the specific orientation, be constructed and operate in the specific orientation. Therefore, the above terms of orientation or positional relationships cannot be understood or interpreted as limitations on the solutions of the present utility model.
[0035] In addition, in the description of this specification, the meaning of "a plurality of" is at least two, such as two, three or more, etc., unless otherwise specifically and clearly defined.
