Description

Technical Field

[0001] This application relates to the technical field of pipe fitting processing, and more particularly to a pipe fitting flaring device. Background Technology

[0002] Shortened bends are often complicated by the length of the pipe, and repeated adjustments to their position can complicate the process. Therefore, a method of directly pressing in expansion balls is used to flare the ends of shortened bends. This flaring device for shortened bends includes a hydraulic press, a placement platform, a push rod, and two expansion balls. During operation, the operator places the bend on the placement platform, puts one expansion ball inside, and then places the push rod on the expansion ball. The hydraulic press is then activated, pressing down on the expansion ball, which is then pushed into the bend. The operator then places the other expansion ball into the bend and continues to place the push rod on it. The hydraulic press is activated again, pressing down on the expansion ball, causing the first expansion ball to be pushed out of the bend, thus flaring the end of the bend.

[0003] However, during the aforementioned pipe bending and flaring process, relevant personnel need to repeatedly pick up and put down the flaring ball, which makes the pipe bending work time-consuming and labor-intensive. Furthermore, when the push rod is pressed down on the flaring ball, relevant personnel need to manually place the push rod, which poses certain safety hazards for pipe bending and flaring. Summary of the Invention

[0005] Therefore, the purpose of this application is to provide a pipe flaring device that eliminates the need for repeated handling of the flaring ball, thereby reducing the labor intensity of relevant personnel, improving the efficiency of pipe bending and flaring, and eliminating the need for manual placement of the jack, thus ensuring the production safety of pipe bending and flaring.

[0006] To achieve the above objectives, this application proposes a pipe flaring device, comprising a hydraulic assembly, a placement platform, a transfer rack, a lifting assembly, multiple transfer frames, a feeding component, a transfer cylinder, and a feeding assembly. The hydraulic assembly includes a pressure plate, on which a one-way feeding component and a push rod are mounted. The one-way feeding component is throttle-connected to the lifting assembly.

The transfer rack is equipped with a feeding frame, one end of which is connected to the bottom of the placement platform, and the other end of which is intermittently connected to the corresponding transfer frame. The lifting assembly is rotatably mounted on the transfer rack. Multiple transfer frames are respectively disposed on the lifting assembly and intermittently connected to one end of the transfer cylinder. Each of the multiple transfer frames is provided with an expanding tube ball, and the push rod presses against the corresponding expanding tube ball.

The material feeding component slidably abuts against the corresponding transfer frame. The transfer cylinder is disposed on the transfer frame. The feeding assembly is disposed on the hydraulic assembly. One end of the feeding assembly is connected to the top of the placement platform, and the other end of the feeding assembly is connected to the other end of the transfer cylinder.

[0007] In addition, the pipe flaring device proposed above according to this application may also have the following additional technical features: In one embodiment of this application, the hydraulic assembly further includes a hydraulic telescopic rod and a support frame, wherein the hydraulic telescopic rod is disposed on the support frame, the placement platform and the feeding assembly are disposed on the support frame, and the pressure plate is slidably disposed on the support frame.

[0008] In one embodiment of this application, the one-way lever includes a lever and a one-way baffle, wherein the lever and the one-way baffle are respectively disposed on the pressure plate; the one-way baffle is disposed at the bottom of the lever and abuts against the lever; the lever is drively connected to the lifting assembly.

[0009] In one embodiment of this application, the lifting assembly includes multiple one-way support members, two sprocket members, and multiple sets of transmission rods. The multiple one-way support members are respectively disposed on the transfer frame, and the multiple one-way support members are respectively engaged with the corresponding transmission rods. The two sprocket members are respectively disposed on both sides of the transfer frame. The ends of the multiple sets of transmission rods are respectively connected to the corresponding sprocket members, and the transfer frame is fixedly connected to one set of transmission rods.

[0010] In one embodiment of this application, the material feeding component includes a material feeding rod and a return spring, wherein the material feeding rod is disposed in the material feeding groove and slidably connected to the material feeding groove, and the material feeding rod slidably abuts against the material transfer frame; one end of the return spring is connected to the material transfer frame, and the other end of the return spring is connected to the material feeding component.

[0011] In one embodiment of this application, the feeding assembly includes a support platform and two elastic clamping members, wherein the support platform is disposed on the hydraulic assembly; the two elastic clamping members are disposed on the support platform; one end of the elastic clamping member is disposed on the placement platform, and the other end of the elastic clamping member is connected to the transfer cylinder.

[0012] In one embodiment of this application, the elastic clamping component includes a clamping plate and an elastic telescopic rod, wherein the clamping plate is slidably disposed on the support platform, one end of the clamping plate is disposed on the placement platform, and the other end of the clamping plate is disposed on one side of the transfer cylinder; the elastic telescopic rod is disposed on the support platform and connected to the clamping plate.

[0019] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0020] The pipe flaring device of this application embodiment will be described below with reference to the accompanying drawings.

[0021] like Figures 1-7 As shown, the pipe flaring device of this application embodiment may include a hydraulic component 1, a placement platform 2, a material transfer rack 3, a lifting component 4, multiple material transfer frames 5, a material feeding component 6, a material transfer cylinder 7, and a feeding component 8.

[0022] The hydraulic component 1 may include a pressure plate 12, on which a one-way deflector 120 and a push rod 92 are provided. The one-way deflector 120 is connected to the lifting component 4 in a transmission manner.

[0023] In the embodiment of the application, the hydraulic component 1 is used to drive the pressure plate 12 to move up and down. When the pressure plate 12 moves downward, it drives the push rod 92 to move downward, pressing down on the expansion ball 93 included in the device. This eliminates the need for manual placement of the push rod 92, ensuring the safety of the flaring process of the bend 94. When the pressure plate 12 moves upward (i.e., during the resetting process of the hydraulic component 1), it drives the one-way lever 120 to move upward, which in turn pushes the lifting component 4 upward.

[0024] In this embodiment, the one-way lever 120 is used to control the movement of the lifting assembly 4 in one direction. When the one-way lever 120 moves upward, it drives the lifting assembly 4 to lift the transfer frame 5. When the one-way lever 120 moves downward with the pressure plate 12, its one-way baffle 1201 abuts against the lever 1200 to restrict the lever 1200 from rotating in the opposite direction. The lever 1200 cannot form an effective engagement with the transmission rod 42 of the lifting assembly 4, so it will not drive the lifting assembly 4 to be lifted upward.

[0025] The placement platform 2 is mounted on the hydraulic assembly 1.

[0026] In this embodiment, the placement platform 2 is used to place the bent pipe 94.

[0027] Understandably, the placement platform 2 is designed according to the shape of the bent pipe 94 to ensure the placement and fixation of the bent pipe 94.

[0028] The transfer rack 3 is equipped with a feeding rack 31. One end of the feeding rack 31 is connected to the bottom of the placement table 2, and the other end of the feeding rack 31 is intermittently connected to the corresponding transfer frame 5.

[0029] In this embodiment, the feeding rack 31 is a downwardly inclined sliding rack body, which is used to slide and transport the expanded tube ball 93 that leaks out from the bottom of the placement table 2 after the bent tube 94 is flared along the rack body to the corresponding transfer frame 5.

[0030] It should be noted that the feeding rack 31 described in this embodiment is a common material feeding rack designed from high to low, which is existing technology, and its specific structure will not be described in detail here.

[0031] It should be noted that the transfer rack 3 described in this embodiment is located on one side of the hydraulic component 1, that is, on one side of the hydraulic component 1 support frame 11.

[0032] Specifically, under the continuous lifting state of the lifting component 4, each transfer frame 5 will intermittently connect with the bottom of the feeding frame 31, so that the tube expanding ball 93 slides down onto the transfer frame 5. The intermittent connection between each transfer frame 5 and the bottom of the feeding frame 31 realizes the movement and feeding of the tube expanding ball 93 onto the transfer frame 5.

[0033] The lifting component 4 is rotatably mounted on the transfer rack 3.

[0034] In this embodiment, the lifting component 4 is used to control the lifting of the transfer frame 5, thereby lifting the tube expansion ball 93 and conveying it into the transfer cylinder 7. In addition, a receiving plate 70 can be provided on the transfer cylinder 7 to ensure the unloading of the tube expansion ball 93.

[0035] Multiple transfer frames 5 are respectively set on the lifting assembly 4 and intermittently connected to one end of the transfer cylinder 7. Each of the multiple transfer frames 5 is provided with a tube expanding ball 93, and the push rod 92 presses against the corresponding tube expanding ball 93.

[0036] In this embodiment, the transfer frame 5 is used to receive the tube expansion ball 93 conveyed by the feeding rack 31.

[0037] The material feeding component 6 is set on the material transfer frame 3 and is slidably set in the material feeding groove 30 opened on the material transfer frame 3. The material feeding component 6 slides and abuts against the corresponding material transfer frame 5.

[0038] In this embodiment, the material feeder 6 is used to feed out the expansion ball 93 on the transfer frame 5 and feed the expansion ball 93 into the transfer cylinder 7.

[0039] It should be noted that the feeding groove 30 described in this embodiment is inclined upward to ensure that the material transfer frame 5 abuts against the feeding component 6 upward. Furthermore, the inclined setting allows the feeding component 6 to move to a designated side (i.e., the direction of the material transfer cylinder 7) after being abutted by the material transfer frame 5, thereby ensuring the feeding effect of the feeding component 6.

[0040] The material transfer cylinder 7 is mounted on the material transfer frame 3.

[0041] In this embodiment, the transfer cylinder 7 is used to receive the expanding ball 93 on the transfer frame 5 and transport the expanding ball 93 to the feeding assembly 8.

[0042] The feeding component 8 is mounted on the hydraulic component 1. One end of the feeding component 8 is connected to the top of the placement platform 2, and the other end of the feeding component 8 is connected to the other end of the rotating cylinder 7.

[0043] In this embodiment, the feeding assembly 8 is used to transport the expanding ball 93 from the transfer cylinder 7 to the top of the placement platform 2 and above the top opening of the bend 94. When the push rod 92 presses down on the expanding ball 93, the expanding ball 93 is pushed away by the feeding assembly 8 and enters the bend 94 to complete the expanding action.

[0044] Specifically, during actual operation, the relevant personnel install the bent pipe 94 fitting into the pipe groove 20 of the placement platform 2. In the initial state, a tube expander ball 93 to be used is limited and supported between the two elastic clamping parts 81 of the feeding component 8. A tube expander ball 93 is also pre-stored on the inclined frame of the feeding rack 31 (the tube expander ball 93 is limited by the end of the feeding rack 31 and is in a static state waiting to be conveyed). After the device is started, the hydraulic component 1 resets and drives the pressure plate 12 to move upward. The one-way lever 120 on the pressure plate 12 moves upward accordingly, and its lever 1200 forms a locking with the transmission rod 42 of the lifting component 4, thereby driving the lifting component 4 to lift upward. When the lifting component 4 moves upward, it will drive multiple transfer frames 5 to rise synchronously. When one of the transfer frames 5 that does not carry the tube expander ball 93 moves to align with the discharge end of the feeding rack 31, the tube expander ball 93 on the feeding rack 31 slides along the inclined frame into the fixed groove 50 of the transfer frame 5 under the action of gravity.

[0045] As the lifting component 4 is lifted upwards, the transfer frame 5, which is being lifted towards the transfer cylinder 7, gradually comes into contact with the feeding component 6. The transfer frame 5 continues to move upwards, causing the feeding component 6 to slide within the feeding groove 30. The feeding component 6 gradually moves the expanding ball 93, causing the expanding ball 93 on the transfer frame 5 to move into the transfer cylinder 7 (at this time, the hydraulic component 1 has completed its reset). The expanding ball 93 moves from the high end to the low end of the transfer cylinder 7 and moves to the feeding component 8, where it is limited above the bent pipe 94. The hydraulic component 1 then... The downward pressure causes the pressure plate 12 to drive the push rod 92 to continuously press against the expanding ball 93. This expanding ball 93 then moves the existing expanding ball 93 inside the bend 94 to continue expanding the unexpanded end of the bend 94. After the bend 94 is expanded, the subsequent expanding ball 93 continues to press down on the previous one. When both expanding balls 93 have passed through the expanded ends of the bend 94, they fall from the opening at the bottom of the tube groove 20 on the placement platform 2 under gravity, and then slide onto the feeding rack 31, achieving the cyclical recycling of the expanding balls 93. The relevant personnel can then remove the bend 94, install another bend 94, and repeat the above operation.

[0046] In one embodiment of this application, such as Figure 3 As shown, the hydraulic assembly 1 may also include a hydraulic telescopic rod 10 and a support frame 11.

[0047] The hydraulic telescopic rod 10 is mounted on the support frame 11, the placement platform 2 and the feeding assembly 8 are mounted on the support frame 11, and the pressure plate 12 is slidably mounted on the support frame 11.

[0048] It is understandable that the pressure plate 12 (the shape of the pressure plate 12 is as follows) Figure 2 (As shown) It is sleeved on the support frame 11, so that the pressure plate 12 can drive the one-way lever 120, so that the one-way lever 120 can drive the lifting assembly 4.

[0049] In one embodiment of this application, such as Figure 4 and Figure 6 As shown, the one-way lever 120 may include a lever 1200 and a one-way baffle 1201.

[0050] The lever 1200 and the one-way baffle 1201 are respectively disposed on the pressure plate 12. The one-way baffle 1201 is disposed at the bottom of the lever 1200 and abuts against the lever 1200. The lever 1200 is connected to the lifting assembly 4 in a transmission manner.

[0051] It should be noted that the lever 1200 described in this embodiment is connected to the transmission rod 42 in the lifting assembly 4.

[0052] In one embodiment of this application, such as Figure 5 and Figure 6 As shown, the lifting assembly 4 may include multiple unidirectional support members 40, two sprocket members 41, and multiple sets of transmission rods 42.

[0053] Multiple unidirectional support members 40 are respectively installed on the transfer frame 3, and the multiple unidirectional support members 40 are respectively engaged with the corresponding transmission rods 42. Two sprockets 41 are respectively installed on both sides of the transfer frame 3. The ends of multiple sets of transmission rods 42 are respectively connected to the corresponding sprockets 41. The transfer frame 5 is fixedly connected to a set of transmission rods 42.

[0054] It should be noted that the lever 1200 in the one-way lever 120 can rotate around the connection point with the pressure plate 12. The one-way baffle 1201 is fixed to the bottom of the lever 1200 and abuts against it, restricting the lever 1200 from rotating away from the lifting assembly 4. When the pressure plate 12 moves upward, the lever 1200 rotates towards the lifting assembly 4 and engages with the transmission rod 42, thereby driving the transmission rod 42 to rise. When the pressure plate 12 moves downward, the lever 1200 is subjected to the reaction force of the transmission rod 42. Due to the limitation of the one-way baffle 1201, it cannot rotate in the opposite direction and can only disengage from the transmission rod 42, thus failing to drive the lifting assembly 4 to move. Since the one-way support 40 described in this embodiment has the same structure as the one-way lever 120, it will not be described in detail here. In addition, the one-way support 40 can also be a common one-way transmission component on the market, which will not be described in detail here.

[0055] Understandably, there are at least two transmission rods 42 in a set to ensure the material loading effect of the transfer frame 5 on the expanding ball 93.

[0056] It should be noted that the sprocket component 41 described in this embodiment is a common component on the market, which includes a chain and gears, and multiple transmission rods 42 are arranged on the chain or connected to the chain through connecting blocks.

[0057] In one embodiment of this application, such as Figure 5 and Figure 6 As shown, the feeding component 6 may include a feeding rod 60 and a return spring 61.

[0058] The material feeding rod 60 is set in the material feeding groove 30 and is slidably connected to the material feeding groove 30. The material feeding rod 60 is also slidably abutting against the material transfer frame 5. One end of the return spring 61 is connected to the material transfer frame 3, and the other end of the return spring 61 is connected to the material feeding component 6.

[0059] Understandably, by setting the reset spring 61, the feeding rod 60 can quickly reset after feeding a single expanding ball 93, thereby ensuring feeding of the next expanding ball 93.

[0060] In one embodiment of this application, such as Figure 3 and Figure 7 As shown, the feeding assembly 8 may include a support platform 80 and two elastic clamping members 81.

[0061] The support platform 80 is mounted on the hydraulic assembly 1, and two elastic clamping components 81 are mounted on the support platform 80. One end of the elastic clamping component 81 is mounted on the placement platform 2, and the other end of the elastic clamping component 81 is connected to the rotating drum 7.

[0062] It is understandable that by setting the elastic clamping part 81, when the push rod 92 presses against the expanding ball 93, the expanding ball 93 can push away the elastic clamping part 81, so that the expanding ball 93 can be pressed into the bend 94.

[0063] In one embodiment of this application, such as Figure 3 and Figure 7 As shown, the elastic clamping member 81 may include a clamping plate 810 and an elastic telescopic rod 811.

[0064] The clamping plate 810 is slidably mounted on the support platform 80. One end of the clamping plate 810 is mounted on the placement platform 2, and the other end of the clamping plate 810 is mounted on one side of the rotating cylinder 7. The elastic telescopic rod 811 is mounted on the support platform 80 and connected to the clamping plate 810.

[0065] It should be noted that one end of the clamping plate 810 described in this embodiment is provided with a positioning plate 8100 (not shown in the figure), which can limit the position of the expanding tube ball 93.

[0066] In one embodiment of this application, such as Figure 2 As shown, a pipe groove 20 is provided on the placement platform 2, and a baffle block 21 is provided at the bottom of the placement platform 2.

[0067] It should be noted that the shape of the pipe groove 20 described in this embodiment is the same as that of the bend 94, and the bend 94 is vertically arranged in the pipe groove 20. The bottom of the bend 94 abuts against the baffle block 21, and the height of the baffle block 21 protruding in the pipe groove 20 is less than the thickness of the pipe wall of the bend 94.

[0068] In one embodiment of this application, such as Figure 2 , Figure 5 and Figure 6 As shown, a fixed material groove 50 is provided on the material transfer frame 5, and a baffle plate 51 is provided at the bottom of the material transfer frame 5. The baffle plate 51 is slidably connected to the feeding frame 31. A through groove 510 is provided on the baffle plate 51, and the feeding component 6 passes through the through groove 510.

[0069] Understandably, by setting the fixed material trough 50, the expanding tube ball 93 can be positioned on the transfer frame 5, and the stability of the expanding tube ball 93 during the lifting process can be guaranteed.

[0070] It should be noted that the transfer frame 5 described in this embodiment is provided with side baffles (not shown in the figure) to prevent the expanding ball 93 from falling to both sides and to ensure the conveying effect of the expanding ball 93.

[0071] It should be noted that the material feeding component 6 passing through the through groove 510 described in this embodiment means that the material feeding rod 60 in the material feeding component 6 passes through the through groove 510.

[0072] Specifically, in actual operation, the relevant personnel install the bent pipe 94 fitting in the pipe groove 20 of the placement platform 2. The bottom of the bent pipe 94 abuts against the baffle block 21. At this time, there is already a pipe expanding ball 93 on both clamping plates 810 and the feeding rack 31. When the device is started, the hydraulic telescopic rod 10 extends (the hydraulic telescopic rod 10 is connected to the hydraulic system, which is not shown), which drives the pressure plate 12 to move downward. The pressure plate 12 pushes the top rod 92 to move downward (at this time, the lever 1200 will not drive the transmission rod 42 to move), so that after the top rod 92 abuts against the pipe expanding ball 93, the hydraulic telescopic rod 10 continues to extend, thereby pressing the pipe expanding ball 93 into the bent pipe 94.

[0073] The hydraulic telescopic rod 10 retracts and resets, causing the pressure plate 12 to move upward. At this time, the lever 1200 engages with the transmission rod 42, causing the transmission rod 42 to move upward on the sprocket 41. The transmission rod 42 also causes the transfer frame 5 and the expansion ball 93 to move upward. At this time, the expansion ball 93 on the feeding frame 31 moves towards the transfer frame 5, which is not equipped with an expansion ball 93 and is lifted to the feeding frame 31.

[0074] As the transmission rod 42 is lifted upwards, the material transfer frame 5, which is lifted towards the material transfer cylinder 7, gradually comes into contact with the material transfer rod 6 of the material transfer component 6. Since the material transfer groove 30 is inclined upwards, as the material transfer frame 5 continues to move upwards, it will push the material transfer rod 60 to slide along the material transfer groove 30 towards the side of the material transfer cylinder 7. During the sliding process, the material transfer rod 60 pushes the expanding tube ball 93 in the fixed material groove 50 of the material transfer frame 5, causing the expanding tube ball 93 to slide out of the material transfer frame 5 and fall into the material transfer cylinder 7 (at this time, the hydraulic telescopic rod 10 is reset). The material transfer cylinder 7 is inclined, and the expanding tube ball 93 slides from the high end to the low end of the material transfer cylinder 7 under the action of gravity, and finally moves between the clamping plates 810 of the two elastic clamping components 81. It is limited to the upper part of the bent tube 94 by the elastic clamping force of the clamping plates 810, waiting for the top rod 92 to press down. The hydraulic telescopic rod 10 operates and presses down again, causing the pressure plate 12 to drive the top rod 92 to continuously press the expanding ball 93. The expanding ball 93 drives the existing expanding ball 93 in the bend 94 to continue to expand the unexpanded bend 94. After the bend 94 is expanded, the two expanding balls 93 leak out of the bend 94 and move to the feeding rack 31. The relevant personnel remove the bend 94, install another bend 94, and repeat the above operation.

[0075] In summary, the pipe flaring device of this application embodiment eliminates the need for repeated handling of the flaring ball, thereby reducing the labor intensity of relevant personnel, improving the efficiency of pipe bending and flaring, and eliminating the need for manual placement of the top rod, thus ensuring the production safety of pipe bending and flaring.
