Description

Technical Field

[0001] The present application relates to the field of mechanical processing technology, and in particular to a pipe orifice shaping tool. Background Art

[0002] Pipe orifice shaping is a common operation during pipeline manufacturing, installation or maintenance. For example, the nozzles of aircraft heat exchangers have high quality requirements. Pipe orifice shaping can ensure the flatness and geometry of the pipe joints, thereby improving the sealing performance. It can also improve the fluid dynamics of the pipe joints and reduce the resistance and pressure loss when the fluid flows through the pipe joints. Pipe orifice shaping plays an important role in pipeline manufacturing, installation and maintenance. It can improve the performance and quality of pipe joints and improve the safety, reliability and economy of the pipeline system. The existing pipe orifice shaping and rounding technology has the problems of complex operation and low efficiency.

[0003] Therefore, based on the above problems, the prior art needs to be improved. Utility Model Content

[0004] The purpose of this application is to improve the efficiency of pipe orifice shaping.

[0005] The above-mentioned technical purpose of the present application is achieved through the following technical solutions: a pipe mouth shaping tool, including an outer hoop for surrounding the outside of the pipe mouth, and also including a thrust plate, which is arranged inside the pipe mouth, the thrust plate is hollow and provided with a penetration channel, the inner wall of the penetration channel is provided with a threaded structure, the thrust plate is sleeved with a screw through the penetration channel, the screw is provided with a top block, and the distance between the top block and the thrust plate is adjusted by rotating the screw relative to the thrust plate; a movable block is slidably provided on a side of the thrust plate close to the top block, the movable block is provided with a shaping piece, the top block is provided with a guide surface, and the movable block can slide on the thrust plate toward or away from the inner wall of the pipe mouth through the guidance of the guide surface, and the outer hoop is provided with a shaping groove concave in the corresponding shaping piece.

[0006] By adopting the above technical solution, the distance between the top block and the thrust plate can be accurately adjusted through the structure of the screw and the top block, thereby controlling the depth and strength of the shaping and ensuring the accuracy and consistency of the shaping effect. The design of the movable block enables the shaping piece to slide in the direction of the inner wall of the pipe orifice, and the tool can adapt to different pipe orifice sizes and shapes, thereby improving the applicability and flexibility of the tool. The shaping groove on the outer hoop corresponds to the inner concave of the shaping piece, ensuring the stability and accuracy of the shaping piece during the shaping process, preventing it from shifting or swinging, and thus ensuring the consistency and quality of the shaping effect.

[0007] Optionally, a guide groove is provided on the movable block, and the top block is installed in the guide groove and abuts against the movable block through the guide surface.

[0008] By adopting the above technical solution, a guide groove is provided on the movable block, and the top block is installed through the guide groove. The movement of the top block and the movable block during the shaping process is well guided, ensuring the stability and accuracy of the shaping process. The design of the guide groove and the guide surface can reduce the friction between the movable block and the top block, thereby reducing the energy loss during the shaping process, improving the efficiency of the tool, and extending the service life of the tool. The movable block is in contact with the top block through the guide surface, which can achieve precise alignment and matching, ensuring that the shaping piece can be shaped in the correct position, avoiding errors and poor shaping effects.

[0009] Optionally, a slide groove is concavely provided on the thrust plate, a slider is provided on the movable block, the slider is embedded in the slide groove, and the movable block moves along the slide groove toward or away from the inner wall of the pipe mouth.

[0010] By adopting the above technical solution, through the design of the chute and the slider, the movable block can move smoothly along the chute toward or away from the inner wall of the pipe mouth. This design makes the shaping process smoother and reduces factors that may cause damage to the pipe mouth or uneven shaping. The cooperation of the chute and the slider can realize precise control of the movement of the movable block. The operator can achieve the desired shaping effect by adjusting the sliding speed and distance, which enhances the operability and flexibility of the tool. The design of the chute and the slider reduces the friction between the moving parts, reduces the energy loss and wear of the shaping tool during use, and extends the service life of the tool. The structure of the chute and the slider enhances the stability of the movable block on the thrust plate, avoids the deviation or loss of control of the movable block during movement, and ensures the safety and accuracy of the shaping process.

[0011] Optionally, there are multiple movable blocks.

[0012] By adopting the above technical solution, multiple movable blocks are distributed on the thrust plate, which can achieve a more uniform pressure effect. When the shaping tool applies force, multiple movable blocks can evenly disperse the force, avoiding uneven shaping or damage to the pipe mouth caused by excessive force on some parts during the shaping process. The design of multiple movable blocks can enhance the stability of the shaping tool during use. They can support and cooperate with each other to ensure that the movable blocks will not deviate or shake during the shaping process, thereby improving the accuracy and reliability of the shaping process. The design of multiple movable blocks enables the shaping tool to better adapt to pipe mouths of different shapes and sizes. They can freely adjust the position and angle according to the specific situation of the pipe mouth, ensuring that the shaping tool can effectively adapt to various pipe mouth shapes and sizes, improving the versatility and scope of application of the tool. Multiple movable blocks can apply force to the pipe mouth at the same time, thereby improving the working efficiency of the shaping tool. Compared with the design of a single movable block, multiple movable blocks can handle a larger shaping area at the same time, reducing the time of the shaping process and improving work efficiency.

[0013] Optionally, the outer hoop includes a first hoop and a second hoop, the first hoop is provided with a first connecting block, the first connecting block is provided with a first mounting hole, the second hoop is provided with a second connecting block, the second connecting block is provided with a second mounting hole, and the first hoop cooperates with the second hoop to clamp the outside of the pipe mouth.

[0014] By adopting the above technical solution, through the design of the first hoop and the second hoop, the shaping tool can firmly clamp the outside of the pipe mouth. The connecting block and the mounting hole between the two hoops can ensure that they remain aligned and fixed during use, thereby improving the clamping force and stability of the tool on the pipe mouth. The mounting holes on the first connecting block and the second connecting block enable the shaping tool to be conveniently installed on the pipe mouth. The operator can complete the installation by fixing the first hoop and the second hoop on both sides of the pipe mouth respectively, which is simple and quick, and improves the convenience and flexibility of the tool. The design of the first hoop and the second hoop enables the shaping tool to adapt to pipe mouths of different sizes and shapes. They can be adjusted and fixed according to the specific conditions of the pipe mouth, ensuring that the shaping tool can effectively adapt to the shaping needs of various pipe mouths, thereby improving the versatility and scope of application of the tool. The firm clamping can ensure that the shaping tool remains stable during use, and the shaping effect will not be affected by looseness or swinging. This design can improve the stability and accuracy of the shaping process, and ensure the smooth progress of the shaping work and the realization of good results.

[0015] Optionally, a thrust bearing is provided on the screw rod, and the thrust bearing is arranged on a side of the thrust plate away from the top block.

[0016] By adopting the above technical solution, the presence of the thrust bearing reduces the friction of the screw on the thrust plate. This can reduce energy loss and improve the rotation efficiency of the screw, making the shaping process smoother. The thrust bearing, as a supporting device, can ensure that the screw remains stable during rotation. This can avoid the deflection or swing of the screw and ensure the accuracy of the transmission and application of force during the shaping process. The presence of the thrust bearing reduces the wear between the screw and the thrust plate. By reducing friction, the service life of the shaping tool can be extended and the maintenance cost can be reduced. The reduced friction and increased stability make it easier for the operator to control the shaping tool, improving the comfort and accuracy of the operation.

[0017] Optionally, a nut is provided on the screw rod, and the nut cooperates with the thrust plate to clamp the thrust bearing.

[0018] By adopting the above technical solution, the design of the nut can ensure that the thrust bearing is firmly fixed on the thrust plate, avoiding the problem of unstable or inaccurate shaping effect caused by loose thrust bearing during shaping process. The assembly process of shaping tool can be simplified by the cooperation of nut and thrust plate. The operator can fix the thrust bearing by simply installing the nut on the screw rod correctly, without the need for additional special tools or complicated operation steps. The design of the nut clamping the thrust bearing can ensure the stable position relationship between the thrust bearing and the thrust plate. In this way, the displacement or shaking of the thrust bearing during shaping process can be avoided, thereby improving the precision and accuracy of the shaping process. Fixing the thrust bearing by the nut can reduce the friction and vibration between the thrust bearing and the thrust plate, extend the service life of the shaping tool, and reduce the maintenance cost.

[0019] Optionally, a handle is provided on the screw rod.

[0020] By adopting the above technical solution, the design of the handle allows the operator to rotate the screw more easily and adjust the position and strength of the shaping tool. This can improve the convenience and comfort of operation and reduce the labor intensity of the operator. The handle can provide better feel and controllability, and the operator can more accurately adjust the movement of the shaping tool to ensure the precision and accuracy of the shaping process. The handle can better control the operation of the shaping tool, reduce the risk of accidental touch or slippage, and improve the safety of the shaping process. The design of the handle allows the operator to more flexibly adjust the position and angle of the shaping tool to meet the shaping needs of different nozzle shapes and sizes, and improve the scope of application and flexibility of the shaping tool.

[0021] In summary, this application has at least the following beneficial effects:

[0022] 1. Through the structure of the screw and the top block, the distance between the top block and the thrust plate can be accurately adjusted, thereby controlling the depth and strength of the shaping, ensuring the accuracy and consistency of the shaping effect. The design of the movable block enables the shaping piece to slide in the direction of the inner wall of the pipe mouth, and the tool can adapt to different pipe mouth sizes and shapes, improving the applicability and flexibility of the tool. The shaping groove on the outer hoop corresponds to the inner concave of the shaping piece, ensuring the stability and accuracy of the shaping piece during the shaping process, preventing it from deflecting or swinging, and thus ensuring the consistency and quality of the shaping effect.

[0023] 2. The movable block is provided with a guide groove, through which the top block is installed. The movement of the top block and the movable block during the shaping process is well guided, ensuring the stability and accuracy of the shaping process.

[0036] A shaping piece 8 is provided on the movable block 7, and a shaping groove 10 is concavely provided at a position of the outer hoop 1 corresponding to the shaping piece 8. When the movable block 7 slides on the thrust plate 3 close to the wall of the pipe mouth 2, the shaping piece 8 is embedded in the shaping groove 10, and the pipe mouth 2 arranged between the movable block 7 and the outer hoop 1 is squeezed and deformed, so that the shape of the pipe mouth 2 fits the shape of the shaping piece 8 and the shaping groove 10, thereby completing the shaping of the pipe mouth 2.

[0037] In this embodiment, refer to Figure 4-5 , there are multiple movable blocks 7, preferably 4 movable blocks 7; there are guide grooves 11 on the movable blocks 7, and the top block 6 can be installed in the guide grooves 11 when it moves toward the thrust plate 3, and abuts against the movable block 7 through the guide surface 9. As the top block 6 moves toward the thrust plate 3, the top block 6 can more stably push the movable block 7 to move away from the center of the thrust plate 3, so that the shaping member 8 on the movable block 7 abuts against the pipe opening 2, and cooperates with the outer hoop 1 to shape the pipe opening 2. A slide groove 12 is concavely provided on the thrust plate 3, and a slider 13 is provided on the movable block 7.

A handle 18 is provided on the screw rod 5, and the design of the handle 18 allows the operator to rotate the screw rod 5 more easily and adjust the position and strength of the shaping tool. This can improve the convenience and comfort of operation and reduce the labor intensity of the operator.

[0040] The implementation principle of this embodiment is as follows: the user sets the pipe mouth 2 on the movable block 7 on the thrust plate 3, and the outer hoop 1 surrounds and clamps the outside of the pipe mouth 2. By adjusting the screw 5 to rotate, the movable block 7 and the outer hoop 1 initially clamp the pipe mouth 2, and the installation of the pipe mouth 2 is completed. The user holds the handle 18, and by continuing to rotate the handle 18, the screw 5 is driven to rotate clockwise relative to the fixed thrust plate 3. According to the setting of the thread structure, the top block 6 moves in the direction close to the thrust plate 3, and the top block 6 pushes the movable block 7 to move in the direction close to the pipe mouth 2, increasing the clamping force of the movable block 7. When the shaping piece 8 on the movable block 7 and the inner wall of the shaping groove 10 on the outer hoop 1 completely clamp the pipe mouth 2, the shaping of the pipe mouth 2 is completed. After the shaping is completed, the user holds the handle 18 and continues to rotate the handle 18 to drive the screw 5 to rotate counterclockwise relative to the fixed thrust plate 3, and the top block 6 moves away from the thrust plate 3, so that the movable block 7 can slide on the thrust plate 3.
