Description

Technical Field

[0001] This utility model belongs to the field of refractory sleeve processing technology, specifically relating to a flaring device for ceramic tube blanks. Background Technology

[0002] In the foundry industry, refractory ceramic tubes are an indispensable key component in sand casting processes, primarily used as channels for molten iron flow (i.e., gating systems). Their structural integrity and assembly stability directly affect the efficiency of molten iron flow and the forming quality of the castings. Currently, the traditional production of refractory ceramic tubes typically involves using a vacuum extruder to extrude prepared clay into tubular blanks, which are then subjected to subsequent firing processes to form the finished ceramic tubes. Since the required length of the gating system often exceeds the length of a single refractory ceramic tube, in practical applications, multiple ceramic tubes need to be assembled to form a complete gating system. The assembly process relies on the socket structure at the ends of the ceramic tubes for effective connection. Therefore, the processing quality and efficiency of the sockets become one of the core factors restricting the production of refractory ceramic tubes. In existing technologies, there are two main processing methods for sockets: The first process involves extruding and flaring the ends of the ceramic tube blank along its axial direction to directly form a socket structure. However, during the implementation of this process, due to the inherent brittleness and plasticity of the clay material, the axial extrusion process can easily lead to localized stress concentration in the ceramic tube blank, resulting in defects such as cracks and deformation. This significantly reduces the yield rate and increases production costs. Furthermore, it is difficult to guarantee the dimensional accuracy and structural consistency of the socket, which adversely affects the subsequent assembly quality. The second process involves separately die-casting the socket structure and then bonding it to the ceramic tube blank. While this process can mitigate the risk of tube cracking to some extent, it adds extra steps such as separate socket molding, positioning and aligning the blank with the socket, and bonding and curing. This not only prolongs the production cycle and reduces efficiency, making it difficult to meet the demands of large-scale production, but also makes the bonded area susceptible to the properties of the adhesive, bonding process parameters, and environmental factors. This can lead to cracking and detachment during subsequent firing and use, affecting the overall service life and safety of the refractory ceramic tube. In summary, current refractory ceramic tube socket processing technology suffers from low yield and low production efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a ceramic tube blank flaring device to solve the technical defects of low yield and low production efficiency in the existing refractory ceramic tube socket processing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A flaring device for ceramic pipe blanks, comprising: A first conveyor, the top of which is connected to a second conveyor; A support plate is connected to the second conveyor and is located away from the first conveyor; The pressure wheel is rotatably connected to the top of the support plate; A bearing housing has a roller inside, and a sleeve mold is connected in the roller. The sleeve mold is movably connected to the pressing wheel. The unloading cylinder has its drive end extending into the sleeve mold; The drive unit is connected to the roller via a transmission unit.

[0005] Furthermore, the first conveyor and the second conveyor are axially perpendicular, and the bearing plate and the first conveyor are axially coincident.

[0006] Furthermore, the support plate has symmetrical protrusions on the side away from the second conveying member, and mounting holes are provided on the two protrusions; The pressure wheel is rotatably connected to the two mounting holes.

[0007] Furthermore, the two mounting holes are axially aligned.

[0008] Furthermore, the first conveying member and the second conveying member have the same structure.

[0009] Furthermore, the first conveying component includes a linear guide rail, a slider, and a driving unit, wherein the slider is slidably connected to the linear guide rail, and the driving unit is connected to the slider.

[0010] Furthermore, there are two bearing seats, which are connected by a roller.

[0011] Furthermore, the drive body is located on one side of the drum and is parallel to the drum axis.

[0012] Furthermore, the driving body is a motor.

[0013] Furthermore, the transmission unit is a transmission belt.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This technical solution achieves a fundamental optimization of the flaring process through the synergistic effect of the pressure roller and the sleeve mold. On the one hand, the sleeve mold can form a stable radial support for the end of the ceramic tube blank, avoiding the cracking of the blank caused by local stress concentration during traditional axial extrusion. On the other hand, the pressure roller, which is rotatably connected to the bearing plate, can form a rolling fit with the sleeve mold, gradually shaping the tube through uniform circumferential pressure during the flaring process. This replaces the rigid axial impact force in the traditional process, effectively reducing the deformation risk caused by the brittleness of the clay, ensuring the consistency of the socket size of each batch of processed tubes, solving the problem of poor precision in the traditional extrusion process, and fundamentally improving the yield and reducing production costs.

[0015] 2. By utilizing the synergistic effect of the first and second conveying components, the pressing wheel on the bearing plate can smoothly extend into the sleeve mold to squeeze the edge of the blank tube, so that the edge of the blank tube can be flared.

[0016] 3. The two mounting holes allow the two ends of the rotating shaft of the pressure roller to be evenly stressed, avoiding the problem of the pressure roller shifting and shaking during high-speed operation or pressure application. This ensures that the pressure roller always maintains a stable fit with the sleeve mold, thereby ensuring a uniform pressure distribution when flaring the ceramic tube blank.

[0017] 4. The two mounting holes are axially aligned, eliminating the problem of uneven force on the rotating shaft caused by the deviation of the mounting hole axis. Attached Figure Description

[0026] To address the technical deficiencies mentioned in the background section, this embodiment provides a flaring device for ceramic pipe blanks. The present invention will be further described in detail below with reference to the accompanying drawings: like Figures 1-6 As shown, the ceramic tube blank flaring device includes a first conveying component 1, with a second conveying component 2 connected to the top of the first conveying component 1; a bearing plate 3 connected to the second conveying component 2 and located away from the first conveying component 1; a pressing wheel 4 rotatably connected to the top of the bearing plate 3; a bearing seat 6 containing a roller 7, with a sleeve mold 5 connected in the roller 7, and the sleeve mold 5 being movably connected to the pressing wheel 4; a discharge cylinder 8, with its drive end extending into the sleeve mold 5; and a drive body connected to the roller 7 via a transmission unit.

[0027] Addressing the core problem of cracking and deformation of the ceramic tube blank 10 easily caused by traditional axial extrusion flaring processes, this technical solution achieves a fundamental optimization of the flaring process through the synergistic effect of the pressure roller 4 and the sleeve mold 5 in the aforementioned structure. On one hand, the sleeve mold 5 can effectively support the ceramic tube blank 10, from... Figure 5As can be seen, the inner wall of the sleeve mold 5 has a socket section 501, which is adapted to the outer wall of the ceramic pipe blank 10, so that when the sleeve mold 5 rotates, it can drive the ceramic pipe blank 10 placed inside it to rotate together. When the ceramic pipe blank 10 is placed in the sleeve mold 5, since the axial diameter of the ceramic pipe blank 10 and the sleeve mold 5 is always consistent, the outer wall of the end of the ceramic pipe blank 10 maintains a certain distance from the inner wall of the socket section 501. When the pressure wheel 4 applies pressure in the radial direction at the end of the ceramic pipe blank 10, it presses the local stressed part of the ceramic pipe blank 10 tightly against the inner wall of the socket section 501. As the sleeve mold 5 drives the ceramic pipe blank 10 to rotate, the pressure wheel 4 presses the end of the ceramic pipe blank 10 tightly against the socket section 501, so that the end of the ceramic pipe blank 10 forms a socket. To allow for the gradual release of local stress during the forming of the socket of the ceramic tube blank 10, the pressure roller 4 can move in a gradual manner in the radial direction of the sleeve mold 5. Specifically, each rotation of the pressure roller 4 moves a certain distance towards the inner wall of the socket section 501 until the outer wall of the ceramic tube blank 10 is completely fitted with the inner wall of the socket section 501, thus completing the forming of the socket. This avoids the cracking of the blank caused by local stress concentration during traditional axial extrusion. On the other hand, the pressure roller 4, which is rotatably connected to the bearing plate 3, can form a rolling fit with the sleeve mold 5. During the flaring process, it gradually shapes the tube through uniform circumferential pressure, replacing the rigid axial impact force in the traditional process. This effectively reduces the deformation risk caused by the brittleness of the clay, solves the problem of poor precision in the traditional extrusion process, and fundamentally improves the yield and reduces production costs. Furthermore, compared to the drawbacks of traditional methods that combine die-casting and bonding processes, this technical solution achieves a significant leap in socket processing efficiency through integrated processing and automated conveying design. Firstly, the device integrates the entire process of conveying, flaring, and unloading. The ceramic tube blank 10 is extruded from the extruder and loaded into the sleeve mold 5, which is then fixed within the roller 7. Therefore, when the roller 7 is rotated by the drive unit, the ceramic tube blank 10 also rotates. Next, the first conveyor 1, the second conveyor 2, and the bearing plate 3 work together to move the pressure roller 4 into the sleeve mold 5. Then, the edge of the ceramic tube blank 10 is pressed from the edge of the sleeve mold 5, gradually shaping the edge of the ceramic tube blank 10 into the flared shape of the inner wall edge of the sleeve mold 5, thus achieving the flaring operation of the ceramic tube blank 10.

[0028] After the flaring operation of the ceramic tube blank 10 is completed, the first conveyor 1, the second conveyor 2 and the bearing plate 3 work together to remove the pressing wheel 4 from the sleeve mold 5, and finally the flared ceramic tube blank 10 can be taken out.

[0029] In the above steps, the entire process achieves automated flaring and unloading, without the need for additional procedures, significantly shortening the production cycle and solving the pain point of low efficiency in traditional processes. In this design, the first conveyor 1 and the second conveyor 2 are axially perpendicular, and the bearing plate 3 and the first conveyor 1 are axially aligned. In practical application, the first conveyor 1 drives the second conveyor 2 to move along the length of the first conveyor 1, and the second conveyor 2 drives the bearing plate 3 to move along the length of the second conveyor 2. Symmetrically, protrusions are provided on the side of the bearing plate 3 away from the second conveyor 2, and mounting holes are provided on both protrusions. The pressure wheel 4 is rotatably connected to the two mounting holes.

[0030] Furthermore, the two mounting holes are axially aligned, and the two ends of the rotating shaft of the pressure wheel 4 can be perfectly fitted into the two mounting holes on the same axis, fundamentally eliminating the problem of uneven force on the rotating shaft of the pressure wheel 4 caused by the deviation of the mounting hole axis.

[0031] On the one hand, when the sleeve mold 5 drives the pressure wheel 4 to rotate, the coincident axis of the two mounting holes allows the two ends of the rotating shaft of the pressure wheel 4 to bear the radial force evenly, avoiding the bending of the shaft or wear of the mounting hole caused by excessive force on one end and insufficient force on the other end, ensuring that the pressure wheel 4 always operates at a stable speed and there will be no jamming, shaking or eccentric rotation.

[0032] On the other hand, since the two mounting holes are on the same axis, after the pressure wheel 4 is installed, the rotation trajectory of its wheel body will not cause the pressure wheel 4 to tilt or deviate due to the deviation of the mounting holes.

[0033] like Figure 1 As shown, the first conveyor 1 and the second conveyor 2 have the same structure; specifically, the first conveyor 1 includes a linear guide rail, a slider and a drive unit. The slider is slidably connected to the linear guide rail, the drive unit is connected to the slider, the second conveyor 2 is mounted on the slider, and the support plate 3 is mounted on the slider in the second conveyor 2.

[0034] In this design, two bearing seats 6 are provided, connected by a roller 7. The drive unit is located on one side of the roller 7 and is parallel to the roller 7 axis. The drive unit is a motor 9, and the transmission unit is a transmission belt. The two bearing seats 6 provide a stable structure with symmetrical support at both ends of the roller 7, which is significantly superior to support with a single bearing seat 6.

[0035] On the one hand, the double bearing seat 6 can evenly distribute the weight of the roller 7 and the radial force generated during operation to the two support points, avoiding uneven force on the roller 7 caused by single-point support, effectively preventing the roller 7 from bending or shifting when operating at high speed or bearing the pressure of the ceramic tube blank 10, and ensuring that the roller 7 always maintains stable rotation.

[0036] On the other hand, the symmetrical arrangement of the two bearing seats 6 can reduce local wear between the roller 7 and the bearing, extend the service life of the components, and reduce the frequency of equipment maintenance.

[0037] This solution also includes a workbench and a controller. The first conveyor 1, bearing seat 6, unloading cylinder 8 and motor 9 are all installed on the top of the workbench and electrically connected to the controller. The first conveyor 1 is installed at one end of the workbench, and the bearing seat 6, unloading cylinder 8 and motor 9 are installed at the other end of the workbench, with the unloading cylinder 8 located on one side of the bearing seat 6. When the motor 9 is driven, it drives the sleeve mold 5 to rotate through the transmission belt, and the end of the unloading cylinder 8 extends into the sleeve mold 5. After the ceramic tube blank 10 completes the flaring operation, the unloading cylinder 8 pushes the ceramic tube blank 10 out of the sleeve mold 5.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit its protection scope. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that after reading this utility model, they can still make various changes, modifications or equivalent substitutions to the specific implementation of the utility model, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the utility model.
