Description

Technical Field

[0001] This utility model relates to the field of breathable brick technology, and in particular to a breathable brick pressing and molding equipment. Background Technology

[0002] In the iron and steel metallurgical industry, molten steel blowing is a simple ladle refining method for degassing molten steel and removing non-metallic inclusions. Currently, widely used permeable bricks are key functional components in the bottom-blown argon process of ladle refining. After molten steel enters the ladle, argon gas is blown into the molten steel through the permeable bricks for stirring, thereby accelerating the metallurgical process, homogenizing the temperature and chemical composition of the molten steel, promoting the removal of inclusions, or controlling the morphology of inclusions, thus achieving the purpose of refining the molten steel. In existing technologies, the production of permeable bricks involves multiple steps, mainly including raw material preparation, batching, molding, drying, and firing. During pressing and molding, the prepared raw materials are first filled into the mold, and after surface refinement by vibration, compaction, and removal of air bubbles, the bricks are pressed and molded using pressing equipment.

[0003] Chinese patent CN221160829U discloses a molding die for a breathable brick core. The molding cylinder is a hollow, split cone shape. An upper square plate is fixedly installed at the upper end of molding cylinder one and molding cylinder two, and a lower square plate is fixedly installed at the lower end of molding cylinder one and molding cylinder two. A bottom plate is installed at the bottom of the lower square plate. Four support cylinders are provided and fixedly installed at the four upper corners of the upper square plate. An upper wire plate is fixedly installed at the upper part of the support cylinder. A lower wire plate is installed in the bottom inner cylinder of the molding cylinder. A steel shell is placed in the center of the molding cylinder. A polyester film is inserted between the upper and lower wire plates. A tensioning and fixing device is fixedly installed at the upper center of the upper wire plate.

[0004] However, in this technical solution, when fixing and straightening the polyester film, the polyester film is first clamped with clamps, and then the sliding body and fixing ring are stretched upward to fix and straighten the polyester film. But in actual use, after the polyester film is fixed, the raw material needs to be filled into the mold, and then after vibration surface refinement, compaction and removal of air bubbles, it is pressed and formed using a pressing molding equipment. During the vibration process, the raw material and the mold vibrate together, and the polyester film fixed by the clamps may shake during vibration, causing the polyester film to shift. This leads to deformation of the slits formed after the permeable brick core is formed, resulting in poor permeability of inert gas and reducing the yield of permeable bricks. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a breathable brick pressing and molding equipment. By using a limiting clamp and a limiting hole, the stability of the clamped and straightened film during the fixing process is achieved. This solves the problem that the polyester film fixed by the clamp may shake during vibration, causing displacement of the polyester film, resulting in deformation of the slit formed after the breathable brick core is formed, poor permeability of inert gas, and reduced yield of breathable bricks.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A breathable brick pressing and molding device includes a base with positioning holes. A positioning block is inserted into the positioning holes. A bottom plate is fixedly connected to the top of the positioning block. The bottom plate has multiple first mounting holes. A top plate is fixedly connected to the base with multiple second mounting holes. A pair of forming cylinders are snapped onto the bottom plate and fixedly connected by bolts. A thin film passes through the first mounting holes, and one end of the thin film passes through the second mounting holes. A fixing component is used to fix and straighten the thin film and is connected to the top plate.

[0008] Optionally, the fixing component includes a mounting sleeve fixedly connected to the top of the top plate, a plurality of limiting plates fixedly connected to the mounting sleeve, each of the limiting plates having a limiting hole, a limiting clip inserted into the limiting hole, a connecting block fixedly connected to one side of the limiting clip, a fixing clip fixedly connected to one side of the connecting block, and the membrane being secured to the fixing clip.

[0009] Optionally, the fixing clamp includes a rectangular plate and an abutment plate connected together, with a fixing ring rotatably connected to one end of the rectangular plate, and the fixing ring being sleeved with one end of the abutment plate.

[0010] Optionally, a plurality of limiting teeth are fixedly connected to one side of the rectangular plate.

[0011] Optionally, the abutment plate has a wavy structure, and a weakening groove is provided at one end of the abutment plate.

[0012] Optionally, the end of the rectangular plate away from the connecting block has an outward tilting structure.

[0013] Optionally, the limiting clamp includes a plurality of plug-in rods connected to the connecting block, the plug-in rods having an L-shaped structure, one end of the L-shaped structure having a triangular structure.

[0014] Optionally, a plurality of anti-slip strips are fixedly connected to one side of the triangular structure.

[0015] Optionally, the limiting hole has a cross-shaped structure.

[0016] Optionally, the limiting tooth is inclined downward, and one end of the limiting tooth has a pointed structure, which is perpendicular to the side of the rectangular plate.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) The present invention can fix the straightened film by setting a fixing clip, and the fixing clip is installed on the limiting hole by a limiting clip. Thus, during the vibration treatment process, the fixing clip will not shake and cause the film to shift. The slit formed after the permeable brick is formed will not deform, which improves the permeable brick inert gas passage effect and the permeable brick yield.

[0019] (2) The present invention uses a combination of a limiting clamp and a limiting hole. The installation and disassembly structure of the limiting clamp and the limiting hole is simple and easy to operate. It allows the operator to adjust the number of fixing clamps according to the number of the first mounting hole and the second mounting hole, and can ensure the stability of the fixing clamp during vibration.

[0020] (3) By setting the limiting teeth, when the operator uses both hands to straighten the two ends of the film and engage it with the rectangular plate and the abutment plate, the film can be fixed on one side of the abutment plate first so that the limiting teeth limit the film. Then, the fixing ring is bent so that the fixing ring is engaged with the abutment plate, which improves the fixing effect of the rectangular plate and the abutment plate on the film. Moreover, only one person is needed to operate it, without the need for multiple people to cooperate, thus improving work efficiency.

[0021] In summary, this invention has the advantages of preventing the fixing clamp from shaking and causing the film to shift during vibration treatment, ensuring that the slits formed after the permeable brick is formed will not deform, and improving the permeable brick's inert gas passage effect and yield.

[0032] Example

[0033] like Figures 1 to 7As shown, this embodiment provides a breathable brick pressing and molding equipment, including a base 1, a positioning hole 2 on the base 1, a positioning block 5 inserted into the positioning hole 2, a bottom plate 3 fixedly connected to the top of the positioning block 5, a plurality of first mounting holes 4 on the bottom plate 3, a top plate 8 fixedly connected to the base 1, a plurality of second mounting holes 9 on the top plate 8, a pair of forming cylinders 6 snapped onto the bottom plate 3, the pair of forming cylinders 6 being fixedly connected by bolts, a film 7 passing through the first mounting hole 4, one end of the film 7 passing through the second mounting hole 9; and a fixing component, which is used to fix and straighten the film 7, and the fixing component is connected to the top plate 8.

[0034] By using the base plate 3, the film 7 is folded in half and passed through the first mounting hole 4. After multiple films 7 have passed through the first mounting hole 4, the positioning block 5 at the bottom of the base plate 3 is inserted into the positioning hole 2 to install the base plate 3. Then, the multiple films 7 are straightened so that one end of the film 7 passes through the second mounting hole 9 opened on the top plate 8. After the multiple films 7 are straightened, they are connected to the fixing component set on the top of the top plate 8. After the film 7 is straightened and fixed, a pair of forming cylinders 6 are snapped into the base plate 3, and then the pair of forming cylinders 6 are fixedly connected with bolts. At the same time, the forming cylinders 6 are fixedly connected to the base 1 with bolts. The mixed raw materials can be injected into the pair of forming cylinders 6. At this time, the forming equipment can be placed on the vibration equipment for surface refinement, compaction and air bubble removal treatment, and then the forming process is carried out. During the vibration process, the fixing component can effectively fix and straighten the film 7, and the fixing component will not shake, so that the film 7 has a better stability effect during vibration treatment. The slits formed after the permeable brick is formed will not deform, improving the permeable brick inert gas passage effect.

[0035] like Figures 2 to 7As shown, the fixing assembly includes a mounting sleeve 10 fixedly connected to the top of the top plate 8. Multiple limiting plates 11 are fixedly connected to the mounting sleeve 10. Each limiting plate 11 has a limiting hole 12, which is cross-shaped. A limiting clip 15 is inserted into the limiting hole 12. A connecting block 14 is fixedly connected to one side of the limiting clip 15. The limiting clip 15 includes multiple insertion rods connected to the connecting block 14. The insertion rods are L-shaped, with one end of the L-shape being a triangular structure. Multiple anti-slip strips are fixedly connected to one side of the triangular structure. A fixing clip 1 is fixedly connected to one side of the connecting block 14. 3. The film 7 is clamped on the fixing clip 13. The fixing clip 13 includes a rectangular plate 16 and an abutment plate 17 connected to each other. The abutment plate 17 has a wavy structure and a weakening groove is opened at one end of the abutment plate 17. The end of the rectangular plate 16 away from the connecting block 14 has an outward inclined structure. A fixing ring 18 is rotatably connected to one end of the rectangular plate 16. The fixing ring 18 is sleeved with one end of the abutment plate 17. A plurality of limiting teeth 19 are fixedly connected to one side of the rectangular plate 16. The limiting teeth 19 are inclined downward and one end of the limiting teeth 19 has a pointed structure. The pointed structure is perpendicular to the side of the rectangular plate 16.

[0036] When the fixing clip 13 is installed with the mounting sleeve 10, a connecting block 14 is fixedly connected to one end of the fixing clip 13, and a limiting clip 15 is fixedly connected to one side of the connecting block 14. The limiting clip 15 can be inserted into the limiting hole 12. The limiting hole 12 has a cross-shaped structure that matches the limiting clip 15, so that the fixing clip 13 will not deflect after the limiting clip 15 is inserted into the limiting hole 12. The limiting clip 15 includes multiple plug-in rods connected to one side of the connecting block 14. The plug-in rods have an L-shaped structure, and one end of the plug-in rod has a triangular structure. The plug-in rods are elastic structures, so that when the limiting clip 15 is inserted into the limiting hole 12, the plug-in rods can undergo elastic deformation. The triangular structure facilitates the insertion of the plug-in rods. The connector is inserted into the limiting hole 12 and engages with it. During disassembly, one end of the connector can be pinched to cause elastic deformation, allowing it to be pulled out through the limiting hole 12. Multiple anti-slip strips are provided on the triangular surface of one end of the connector to increase friction between the operator's hand and the connector, facilitating the pinching action. The limiting clamp 15 and the limiting hole 12 have a simple installation and disassembly structure, making them easy to operate. The operator can easily adjust the number of fixing clamps 13 according to the number of the first mounting holes 4 and the second mounting holes 9. When assembling the film 7 and the fixing clamps 13, the fixing clamp 13 includes a connected rectangular plate 16 and an abutment plate 17. After the operator straightens the film 7, the film 7 is slid into the rectangular plate 16. At the midpoint between the rectangular plate 16 and the abutment plate 17, the end of the rectangular plate 16 furthest from the connecting block 14 is inclined outwards, while the abutment plate 17 has a wavy, elastic structure. This facilitates the sliding of the film 7 into the midpoint between the rectangular plate 16 and the abutment plate 17. At this point, the operator can pull the film 7 towards the rectangular plate 16 and fold it, allowing the film 7 to pass through the limiting tooth 19. The limiting tooth 19 effectively limits the film 7. The limiting tooth 19 has a downward-sloping structure, and one end of the limiting tooth 19 has a pointed shape. The pointed shape is perpendicular to the side of the rectangular plate 16, facilitating the locking and limiting of the film 7 with the limiting tooth 19. The advantage of this design is that when the operator uses both hands to straighten both ends of the film 7 and the rectangular plate 16, the film 7 can easily be locked in place. When the rectangular plate 16 and the abutment plate 17 are engaged, the film 7 can be fixed to one side of the abutment plate 17 first so that the limiting tooth 19 limits the film 7. Then, the fixing ring 18 is bent so that the fixing ring 18 is sleeved on the abutment plate 17, which improves the fixing effect of the rectangular plate 16 and the abutment plate 17 on the film 7. Only one person is needed to operate it, without the need for multiple people to cooperate. One end of the abutment plate 17 is provided with a weakening groove, which makes it easy for the fixing ring 18 to be sleeved on the abutment plate 17. The fixing clip 13 is used to effectively fix the straightened film 7. The fixing clip 13 is engaged and installed on the limiting hole 12 through the limiting clip 15. Thus, during the vibration treatment, the fixing clip 13 will not shake and cause the film 7 to shift, which improves the yield of the breathable brick.

[0037] Work steps

[0038] In use, when installing the fixing clip 13 and the mounting sleeve 10, a connecting block 14 is fixedly connected to one end of the fixing clip 13, and a limiting clip 15 is fixedly connected to one side of the connecting block 14. The limiting clip 15 can be inserted into the limiting hole 12. Then, the film 7 is folded in half and passed through the first mounting hole 4. After all the films 7 have passed through the first mounting hole 4, the positioning block 5 at the bottom of the base plate 3 is inserted into the positioning hole 2 to install the base plate 3. Then, the films 7 are straightened so that one end of the film 7 passes through the second mounting hole 9 opened on the top plate 8. The film 7 is slid into the middle position between the rectangular plate 16 and the abutment plate 17. The film 7 is then pulled. The membrane 7 is folded towards the rectangular plate 16, so that the membrane 7 passes through the limiting tooth 19. The limiting tooth 19 can effectively limit the membrane 7. Then, the fixing ring 18 is bent so that the fixing ring 18 is sleeved on the abutment plate 17. After the membrane 7 is straightened and fixed, a pair of forming cylinders 6 are snapped to the base plate 3. Then, the pair of forming cylinders 6 are fixedly connected with bolts. At the same time, the forming cylinders 6 are fixedly connected to the base 1 with bolts. The mixed raw materials can be injected into the pair of forming cylinders 6. At this time, the forming equipment can be placed on the vibrating equipment for surface refinement, compaction and air bubble removal treatment before forming.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
