Description

Technical Field

[0001] This application belongs to the field of hot blast stove manufacturing, specifically relating to a jig for making molds for hot blast stove support columns. Background Technology

[0002] A hot blast stove is a device that provides hot air to a blast furnace to aid combustion. The hot blast stove support column, as the main support of the hot blast stove, has strict requirements on its size and shape. Existing support columns are generally manufactured using hot blast stove support column molds.

[0003] Traditional hot blast stove support molds are composed of multiple foam molds assembled together. The process involves pouring heat-resistant cast iron into the mold after assembly, allowing it to cool and solidify, and then machining it to obtain the support column. However, the mold assembly process relies heavily on the skill level of the workers, making it difficult to guarantee mold precision. This can lead to deviations in the size and shape of subsequently produced support columns, affecting the overall installation and performance of the hot blast stove. Furthermore, the lack of effective fixation for multiple foam molds allows individual components to easily shift during casting and molding, necessitating frequent manual measurements and adjustments, resulting in significant manpower and time costs. Utility Model Content

[0004] This application provides a jig for making molds for hot blast stove support columns, aiming to solve the technical problem that in the prior art, the molds for hot blast stove support columns are prone to component displacement during use, which affects the casting quality, tests the operator's skill level, and increases the labor intensity.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] A jig for manufacturing hot blast stove support molds is provided, comprising:

[0007] Base;

[0008] A support assembly is installed on top of the base, the top of the support assembly forming a support groove that is adapted to the outer periphery of the furnace support mold; and

[0009] The fixing component includes two limiting plates spaced apart along a first horizontal direction, which is perpendicular to the long axis of the furnace support mold. The two limiting plates are respectively installed on the top of the base, and a fixing space is formed between the two limiting plates to clamp the end of the furnace support mold. The fixing space is used to limit the displacement of the furnace support mold in the first horizontal direction.

[0010] In one possible implementation, the support assembly includes two support plates, which are respectively mounted on the top of the base and spaced apart along a second horizontal direction, which is perpendicular to the first horizontal direction. The top of each support plate has a connecting groove that extends along the second horizontal direction, and the two connecting grooves cooperate to form the support groove.

[0011] In one possible implementation, the upper surface of the base is provided with a guide line, the guide line being parallel to the second horizontal direction, and the guide line and the arch axis of the support groove being located on the same vertical plane.

[0012] In one possible implementation, two fixing components are provided, and the two fixing components are symmetrically arranged at both ends of the support groove.

[0013] In one possible implementation, the base, the limiting plate, and the support plate are all foam components.

[0014] In one possible implementation, the limiting plate is bonded and fixed to the base, and the support plate is bonded and fixed to the base.

[0015] In one possible implementation, a reinforcing nail is connected to the bottom of the limiting plate, and the reinforcing nail is embedded inside the base.

[0016] In one possible implementation, the base is further provided with a pad block located at the bottom of the fixed space, and the top of the pad block abuts against the end of the furnace support mold.

[0017] In one possible implementation, the limiting plate has an arc-shaped stepped groove on the side near the support groove.

[0018] In one possible implementation, the fixing component further includes a baffle, with two limiting plates connected to its two ends respectively. The baffle is located on the side of the limiting plate away from the support groove, and the surface of the baffle abuts against the end face of the furnace support mold to limit the displacement of the furnace support mold in its own axial direction.

[0019] The jig for manufacturing hot blast stove support column molds provided in this application, compared with the prior art, provides a support jig for hot blast stove support column molds. Support components and limiting plates are respectively installed on a base. Before casting, multiple foam molds of various hot blast stove support column molds are spliced ​​together and placed horizontally on the support groove. The support groove abuts against the outer periphery of the support column mold, supporting the mold. An end protrusion of the support column mold is placed between two limiting plates. After the end protrusion is placed, the two limiting plates respectively limit the movement on both sides of the end protrusion, preventing the foam mold of the support column mold from shifting horizontally during use. The two limiting plates work together to clamp the end protrusion of the furnace support mold, preventing local mold displacement during operation, improving the forming quality of the furnace support, and increasing the yield rate. The casting process is completed in one go, eliminating the need for manual adjustment by employees, greatly reducing labor intensity and time investment, and improving efficiency. The support groove is adapted to the outer circumference of the furnace support mold, and the furnace support mold can be automatically and accurately supported after being placed in the support groove, preventing the furnace support mold from tilting in the vertical direction, providing good support for the furnace support mold, ensuring the accuracy of the shape, and improving the precision of the finished product.

[0037] Please refer to the following: Figures 1 to 5 The following describes the jig for fabricating the hot blast stove support mold 4 provided in this application. The jig for fabricating the hot blast stove support mold 4 includes a base 1, a support component 2, and a fixing component 3. The support component 2 is installed on the top of the base 1, and a support groove is formed on the top of the support component 2. The support groove is adapted to the outer periphery of the furnace support mold 4. The fixing component 3 includes two limiting plates 31 spaced apart along a first horizontal direction. The first horizontal direction is perpendicular to the long axis of the furnace support mold 4. The two limiting plates 31 are respectively installed on the top of the base 1, and a fixing space is formed between the two limiting plates 31 to clamp the end of the furnace support mold 4. The fixing space is used to limit the displacement of the furnace support mold 4 in the first horizontal direction.

[0038] It should be noted that the base 1 is a rectangular component with a rectangular upper surface, which facilitates the installation of the support component 2 and the limiting plate 31 by employees. The base 1 has a simple shape, is easy to manufacture, and reduces manufacturing difficulty.

[0039] It should be noted that the furnace support mold 4 in the prior art includes a furnace support mold 4 body with a cylindrical shape in the middle, and support plates located at both ends of the furnace support mold 4 body. The axial cross-section of the support plate is rectangular or circular, and its size is larger than the cross-sectional size of the furnace support mold 4 body.

[0040] It should be noted that, for reference Figure 2 In the diagram, the solid arrows indicate the second horizontal direction, while the dashed arrows indicate the first horizontal direction.

[0041] This embodiment provides a support jig for a hot blast stove support column mold. The support assembly 2 and the limiting plate 31 are respectively installed on the base 1. Before the casting work, multiple foam molds of multiple hot blast stove support column molds 4 are spliced ​​together and placed horizontally on the support groove. The support groove abuts against the outer periphery of the support column mold 4 to support the support column mold 4. The end protrusion of the support column mold 4 is placed between the two limiting plates 31. After the end protrusion is placed, the two limiting plates 31 limit it on both sides of the end protrusion to prevent the foam mold of the support column mold 4 from shifting in the horizontal direction during use.

[0042] The jig for manufacturing the hot blast stove support mold 4 provided in this embodiment, compared with the prior art, uses two limiting plates 31 to clamp the end protrusions of the furnace support mold 4, which avoids local mold displacement of the furnace support mold 4 during operation, improves the forming quality of the furnace support, and increases the yield rate; the casting work is completed in one go, eliminating the step of manual adjustment by employees, greatly reducing labor intensity and time investment, and improving efficiency; the support groove is adapted to the outer periphery of the furnace support mold 4, and the furnace support mold 4 can be automatically and accurately supported after being placed in the support groove, avoiding the furnace support mold 4 from tilting in the vertical direction, providing good support for the furnace support mold 4, ensuring the accuracy of the shape, and improving the precision of the finished product.

[0043] In some embodiments, see Figure 1 and Figure 2 The support assembly 2 includes two support plates 21, which are respectively mounted on the top of the base 1 and spaced apart along a second horizontal direction, which is perpendicular to the first horizontal direction. The top of each support plate 21 has a through-groove 211 along the second horizontal direction, and the two through-grooves 211 cooperate to form a support groove. The two support plates 21 can contact the furnace support mold 4 at intervals, avoiding stress concentration caused by concentrated contact points, and preventing the furnace support mold 4 from tilting around the support groove as a bending point. The position of the through-groove 211 is fixed and regular, eliminating the need for frequent manual adjustment of the module position in the furnace support mold 4.

[0044] In practice, the two support plates 21 are at the same height and the docking grooves 211 are at the same size. They support the furnace support mold 4 in the second horizontal direction. The support groove can effectively limit the position and shape of the foam mold, reduce the possibility of mold component displacement during casting and casting, thereby ensuring the accuracy of the final furnace support in terms of size and shape, and avoiding deviation of the furnace support due to mold accuracy issues.

[0045] In some embodiments, see Figure 1 and Figure 2The upper surface of the base 1 is provided with a guide line 11, which is parallel to the second horizontal direction and is located on the same vertical plane as the arch axis of the support groove. The guide line 11 can assist employees in placing the furnace support mold 4. After the employees place the furnace support mold 4 on the support groove, they can use tools or directly observe the positional relationship between the axis of the furnace support mold 4 and the guide line 11 to determine whether the installation position of the furnace support mold 4 is accurate. The operators can accurately align and arrange the molds along the guide line 11, which helps to quickly and accurately complete the assembly of the molds, improve assembly efficiency and accuracy, ensure that each foam mold can be correctly assembled together, and avoid subsequent problems caused by misalignment.

[0046] In some embodiments, see Figure 1 and Figure 2 There are two fixing components 3, which are symmetrically arranged at both ends of the support groove. There are two fixing components 3, with a total of four limiting plates 31, which can limit the furnace support mold 4 at both ends and apply a stable constraint force to prevent displacement or shaking during the casting and casting process. This ensures that the mold maintains a stable position and shape throughout the molding process, greatly improving the stability of the mold.

[0047] In some embodiments, the base 1, the limiting plate 31, and the support plate 21 are all foam components. Foam components are easy to manufacture, low in cost, and lightweight, making them convenient for employees to move to designated locations; they are also easy to process and require little skill from employees. The base 1, the limiting plate 31, and the support plate 21 are all foam components, and they are made of the same material as the main body of the furnace support mold 4, which is assembled using foam molds. During the subsequent casting process, their thermal expansion and other properties are similar, allowing them to work together better and reducing problems such as deformation caused by material differences.

[0048] In some embodiments, the limiting plate 31 is bonded and fixed to the base 1, and the support plate 21 is bonded and fixed to the base 1. The base 1, limiting plate 31, and support plate 21 are all foam components. Bonding satisfies the connection requirements and prevents the limiting plate 31 and support plate 21 from separating from the base 1. The bonded connection surface is relatively flat, providing a uniform stress distribution, reducing the risk of localized damage due to uneven stress at the connection points, and extending the service life of the fixture. Simply apply adhesive to the corresponding areas and then attach them. This bonding method is easier to implement and reduces damage to the foam material caused by additional processing, ensuring the integrity and performance of the foam components.

[0049] In practice, strong adhesives can be used to connect the base 1 and the limiting plate 31, and the support plate 21 and the base 1, such as 502 or industrial adhesives.

[0050] In some embodiments, see Figure 3The bottom of the limiting plate 31 is connected to a reinforcing nail 32, which is embedded inside the base 1. The reinforcing nail 32, embedded inside the base 1, enhances the connection strength between the limiting plate 31 and the base 1, dispersing external forces on the limiting plate 31 to a larger area inside the base 1. When the limiting plate 31 is subjected to lateral forces or pressures from the foam mold or during the casting process, the reinforcing nail 32 transmits and disperses these forces throughout the base 1, preventing excessive localized stress and damage to the limiting plate 31. Inserting and embedding the reinforcing nail 32 into the base 1 eliminates the need for complex tools and processes, reducing manufacturing costs and assembly difficulty.

[0051] In some embodiments, see Figure 5 The base 1 is also equipped with a pad 33, which is located at the bottom of the fixed space. The top of the pad 33 abuts against the end of the furnace support mold 4. The pad 33 can provide support from below the end of the furnace support mold 4, providing additional support points for the furnace support mold 4. When manufacturing the hot blast stove furnace support mold 4, especially for larger or heavier mold components, multiple support points can effectively distribute the weight of the mold, preventing the mold from deforming or sinking due to its own weight or the pressure during the casting process. This ensures that the mold maintains a stable position and shape throughout the manufacturing process, thereby improving the accuracy of the furnace support molding.

[0052] The spacer block 33 also restricts the displacement and deformation of the mold end, avoiding defects such as shrinkage cavities and cracks at the end, ensuring the quality of the furnace support end, improving the strength and sealing of the entire furnace support, and facilitating the normal operation of the hot blast stove. Through stable support and precise end positioning, the spacer block 33 helps the furnace support mold 4 to be heated and stressed evenly during the casting process. This makes the forming of each part of the furnace support more uniform.

[0053] In some embodiments, see Figure 1 The limiting plate 31 has an arc-shaped stepped groove 311 on its side near the support groove. For furnace support columns with arc-shaped ends, the stepped groove 311 can more accurately position the furnace support column, ensuring a higher fit between the mold and the furnace support column, thereby improving the forming accuracy of the furnace support column and making the produced furnace support column more in line with the design requirements in shape and size. The arc-shaped stepped groove 311 cooperates with the support groove to further optimize the support structure of the limiting plate 31 for the furnace support column mold 4. It can provide a more uniform support force, ensuring that the furnace support column mold 4 will not deform due to uneven local stress during casting and other processes, thereby ensuring the forming quality and dimensional accuracy of the furnace support column.

[0054] In some embodiments, see Figure 5The fixing component 3 also includes a baffle 34, with two limiting plates 31 connected to both ends of the baffle 34. The baffle 34 is located on the side of the limiting plates 31 away from the support groove. The surface of the baffle 34 abuts against the end face of the furnace support mold 4 to limit the axial displacement of the furnace support mold 4. The presence of the baffle 34 can effectively limit the axial displacement of the mold and maintain its positional stability. If the mold is displaced axially, it may cause uneven deformation of the furnace support in the length direction, affecting its overall shape accuracy. By limiting this displacement, the baffle 34 enables the furnace support to maintain a stable shape during the forming process, improving the quality and reliability of the product.

[0055] The baffle 34 connects the two limiting plates 31, forming a more stable structural system. This disperses the axial force on the mold onto the entire fixed assembly 3, enhancing the overall stability of the mold structure. The baffle 34 and the limiting plates 31 work together to limit the furnace support mold 4 from different directions. The limiting plates 31 position and constrain the mold in the radial direction, while the baffle 34 provides additional restriction in the axial direction. Together, they form a comprehensive limiting system, ensuring the reliability and stability of the entire mold system.

[0056] In practice, the baffle 34 is also a foam component, which is easy to manufacture and has low cost. The baffle 34 is bonded and fixed to the two corresponding limiting plates 31 with adhesive, which is convenient and quick to operate.

[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
