Description

Technical Field

[0001] This invention relates to the field of copper tube processing technology, and more specifically to a socket-type straight tube processing device. Background Technology

[0002] In pipe connection technology, socket-type straight pipe connection is a commonly used connection method. Socket-type straight pipe connection involves flaring one of the two pipes to be connected, allowing the unflared end of the other pipe to be directly inserted into the flared end, thus achieving a tight connection between the two pipes.

[0003] In the processing of socket-type straight pipes, the flaring machine is one of the key pieces of equipment. A flaring machine typically includes a core driver, a sleeve driver, a flaring core, and a flaring sleeve. The flaring sleeve consists of an upper sleeve and a lower sleeve, which are positioned and fitted together in a specific way to form a cavity for flaring the pipe. However, in existing flaring machines, the alignment of the upper and lower sleeves often relies on the engagement of locating pins and locating holes. This alignment method has the following problems: 1. Difficulty in alignment: To avoid damage to the flaring machine caused by the locating pin failing to insert into the locating hole when the mold sleeve is closed, the size of the locating hole is often designed to be larger than the locating pin to avoid hard collision between the locating pin and the opposite mold sleeve. However, this method also makes it very difficult to align the locating pin and the locating hole. The locating pin must be aligned with the position of the locating hole to ensure both the coaxial alignment of the upper and lower mold sleeves and the relative axial alignment of the upper and lower mold sleeves. This makes the actual operation time-consuming to adjust and difficult to guarantee alignment.

[0004] 2. Unstable processing quality: Due to the difficulty in perfectly aligning the upper and lower mold sleeves, the pipe is subjected to uneven stress during the flaring process, which can easily lead to quality problems such as pipe deformation and cracking, affecting the connection effect and service life of the socket-type straight pipe.

[0005] 3. Low operating efficiency: Due to the difficulty of alignment, operators need to spend a lot of time and energy on debugging and calibration, which reduces processing efficiency. Summary of the Invention

[0006] The present invention aims to provide a socket-type straight pipe processing device to solve the problem of difficulty in aligning the coaxiality of the flaring die sleeve in the existing flaring machine.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A socket-type straight pipe processing device includes a flaring machine. The flaring machine includes a core driver, a sleeve driver, a flaring core, and a flaring sleeve. The core driver is used to insert the flaring core into the hollow structure of the flaring sleeve. The space between the flaring core and the flaring sleeve forms a flaring space. The flaring sleeve includes a first sleeve and a second sleeve, which can be opened / closed by the sleeve driver. The surfaces of the first sleeve and the second sleeve are in a concave-convex fit. At the joint of the first sleeve and the second sleeve, one has a protrusion, and the other has a mating recess. The protrusion is parallel to the pipe, and there is a mating wedge surface between the protrusion and the recess. The mating wedge surface is parallel to the axis of the pipe.

[0008] The principle and advantages of this solution are as follows: This invention utilizes the interlocking convex and concave fit of mold sleeve one and mold sleeve two. When mold sleeve one and mold sleeve two close under the action of the mold sleeve driver, the mating wedge surfaces between the protrusion and concave portions automatically align, ensuring that the circular cavity of the flaring mold sleeve is completely coaxial. This structure not only improves the coaxiality of the flaring process but also allows for automatic adjustment of the coaxial alignment of mold sleeve one and mold sleeve two through the mating wedge surfaces, simplifying the coaxial alignment process, improving processing efficiency, and ensuring consistency in alignment each time mold sleeve one and mold sleeve two close, thereby guaranteeing consistent product quality and reducing the defect rate. Preferably, as an improvement, both mold sleeve one and mold sleeve two are provided with positioning grooves. The depth direction of the positioning grooves is parallel to the moving direction of the output end of the mold sleeve driver. The flaring machine also includes a mold base for fixing mold sleeve one. The mold base is provided with a receiving groove for placing mold sleeve one, and the receiving groove is clearance-fitted with mold sleeve one. A movable seat is fixedly installed on the output end of the mold sleeve driver. The movable seat is used to fix mold sleeve two. The movable seat or the mold base is provided with a positioning block, which is used to simultaneously insert into the positioning grooves of mold sleeve one and mold sleeve two.

[0009] Beneficial effects: When this solution is adopted, when mold sleeve one and mold sleeve two are closed, the axial position alignment of mold sleeve one and mold sleeve two is achieved by the simultaneous cooperation of the positioning block with the positioning groove on the two mold sleeves, which further reduces the difficulty of aligning the flaring mold sleeves and helps to improve the flaring quality.

[0010] Preferably, as an improvement, it also includes a feeder and a transferor. The transferor is used to place the pipe on the feeder into the flaring die sleeve. The transferor includes a translation seat, a lifting device, and a gripper. The translation seat is used to move the gripper closer to / away from the feeder. The lifting device is used to lift the gripper up and down. The gripper is used to pick up the pipe, so as to facilitate the automatic picking up, automatic flaring, and automatic transfer of the pipe after flaring.

[0011] Preferably, as an improvement, the number of grippers is at least two, and the distance L between adjacent grippers projected along the moving direction of the translation seat is equal; it also includes a number of transfer support groups not less than the number of grippers, each transfer support group including at least two transfer support members, the line connecting the transfer support members in the same group is parallel to the flaring die core, the distance between adjacent transfer support groups in the moving direction of the translation seat is equal to L, the transfer support members are used to support the pipe, and one group of transfer support groups is directly opposite the flaring machine.

[0012] Beneficial effects: The settings for the number of grippers, the number of transfer support groups, and various types of spacing in this solution enable the transfer component to feed the pipes one by one each time it is started. This feeding frequency ensures that the pipes are delivered from the transfer support groups to the flaring die of the flaring machine, facilitating flaring directly after the pipes are transferred and improving flaring efficiency.

[0013] Preferably, as an improvement, there is at least one set of transfer support groups between the flaring machine and the feeder, so that the pipes delivered by the feeder can be used on the transfer support groups.

[0014] Preferably, as an improvement, the flaring machine includes a left flaring machine and a right flaring machine, which are located at both ends of the pipe. The distance between the left flaring machine and the right flaring machine in the direction of movement of the translation seat is equal to N times L, where N is an integer greater than or equal to 0.

[0015] Beneficial effects: By using left and right flaring machines, this processing device can flare both ends of the pipe, or select either end for flaring, or complete the same number of single-end flarings within a specified time using both machines, thus meeting the needs of different application scenarios. For example, when only single-end flaring is required, the alternating operation of the left and right flaring machines ensures that the number of left-flared and right-flared pipes processed per unit time is consistent. This facilitates consistency between the left and right ends after flaring, ensuring that the pipes are bundled and packaged for easy transportation and storage. It avoids the problem of pipe packages being tilted when flared only at one end, which can occur when one end is larger than the other, hindering storage and transportation.

[0016] When N equals 0, the left and right flaring machines are located at both ends of the same pipe; when N is greater than 0, the left and right flaring machines are staggered.

[0017] Preferably, as an improvement, the transfer support is provided with a U-shaped or V-shaped support groove to facilitate improved accuracy of the pipe position.

[0018] Preferably, as an improvement, the feeder includes an inclined rack and a feeding assembly. The downward-inclined end of the rack is provided with a limiting stop for blocking the pipes. The feeding assembly includes a lifting pusher, the output end of which is fixed with a push plate. The push plate has an inclined surface, which is used to push one pipe upward at a time. The downward-inclined end of the inclined surface is fixed with a blocking block. The inclination direction of the inclined surface is consistent with the inclination direction of the rack. The feeding assembly is located on the line connecting all the transfer support members of one set of transfer support groups. After the push plate descends, the pipes on the push plate can fall onto one set of transfer support groups.

[0019] Beneficial effects: When using this solution for feeding, each time the lifting pusher moves the top push plate upward, the pipe is pushed out of the material rack to a height exceeding the limit stop. Then the pipe moves downward along the inclined surface and is blocked by the blocking block on the top push plate. The pipe is removed from the material rack and falls onto the transfer support.

[0020] Preferably, as an improvement, at least two discharge rods are fixed on the material rack, each discharge rod including a height limiting section and a guide section. The guide section forms a V-shape with the material rack. The distance between the height limiting section and the material rack is smaller as it gets closer to the baffle plate. The minimum distance between the height limiting section and the material rack allows only one pipe to pass through.

[0021] Beneficial effects: By setting up the discharge rod, this solution ensures that the pipes are arranged in a single layer when they move to the bottom of the rack, so that only one pipe is taken at a time.

[0022] Preferably, as an improvement, the position of the push plate corresponds to the transfer support group closest to the feeder. This solution allows the pipe obtained after the push plate pushes down to fall directly onto the transfer support group, thereby facilitating the transferor to transfer the pipe from the transfer support assembly.

[0023] Preferably, as an improvement, it also includes a linear actuator that moves the left flaring machine and / or the right flaring machine, thereby allowing the distance between the left and right flaring machines to be adjusted to accommodate flaring at both ends of pipes of different lengths or flaring in any direction.

[0035] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: flaring machine 1, worktable 11, mold core driver 12, mold sleeve driver 13, flaring mold core 14, mold sleeve one 15, mold sleeve two 16, protrusion 151, recess 161, mating wedge surface 152, positioning groove 156, mold base 17, moving base 18, positioning block 181, feeder 2, material rack 21, blocking block 211, discharge rod 212, height limiting section 2121, guide section 2122, feeding assembly 22, lifting pusher 221, top push plate 222, inclined surface 2221, blocking block 2222, transfer support assembly 3, transfer support piece, transferor 4, fixed platform 41, translation seat 42, lifting device 43, gripper 44, linear mover 5, pipe 10.

[0036] The basic implementation examples are as follows: Figures 1 to 11 As shown.

[0037] Combination Figure 1 and Figure 2A socket-type straight pipe processing device includes a flaring machine 1, a feeder 2, a transfer support assembly 3, and a transferor 4. The feeder 2 is used to feed the pipe 10 to be flared onto the transfer support assembly 3, and the transferor 4 is used to transfer the pipe 10 from the transfer support assembly 3 onto the flaring machine 1 and to send the flared pipe 10 out of the flaring machine 1.

[0038] I. Detailed Structure of the Flaring Machine Specifically, in combination Figure 3 Hezhi Figure 5 The flaring machine 1 includes a left flaring machine 1 and a right flaring machine 1. The left flaring machine 1 is fixedly installed, and the right flaring machine 1 is fixedly installed on the linear mover 5. After the linear mover 5 is started, it can adjust the distance between the right flaring machine 1 and the left flaring machine 1.

[0039] Both the left flaring machine 1 and the right flaring machine 1 include a worktable 11, a core driver 12, a sleeve driver 13, a flaring core 14, and a flaring sleeve. The flaring core and the flaring sleeve can be coaxial. The core driver 12 is fixed on the worktable 11 and is used to drive the flaring core 14 to be inserted into the hollow structure of the flaring sleeve. In this embodiment, the core driver 12 is a cylinder. The output end of the core driver 12 is fixed to the flaring core 14. The space between the flaring core 14 and the flaring sleeve forms the flaring space of the copper tube.

[0040] The flared mold includes a first mold 15 and a second mold 16 that can be opened / closed by the mold driver 13. In this embodiment, the second mold 16 is located above the first mold 15. A mold base 17 is fixedly installed on the worktable 11. The mold base 17 has a receiving groove for placing the first mold 15. The first mold 15 is detachably connected to the mold base 17 by screws. The receiving groove is clearance-fitted with the first mold 15 so that the first mold 15 can have a small space to move along the horizontal plane on the mold base 17 before it is fixedly connected to the mold base 17.

[0041] The surfaces of mold sleeve 15 and mold sleeve 2 16 that meet are in a concave-convex fit. At the joint of mold sleeve 15 and mold sleeve 2 16, one has a symmetrical protrusion 151, and the other has a concave portion 161 that mates with the protrusion 151. The protrusion 151 is parallel to the pipe 10. There is a mating wedge surface 152 between the protrusion 151 and the concave portion 161. The mating wedge surface 152 is parallel to the axis of the pipe 10. In this embodiment, the angle between the mating wedge surface 152 and the horizontal plane is 45°.

[0042] Both mold sleeve 15 and mold sleeve 2 16 have symmetrical positioning grooves 156. The depth direction of the positioning grooves 156 is parallel to the moving direction of the output end of the mold sleeve driver 13. The flaring machine 1 also includes a mold base 17, which is used to fix mold sleeve 15. A movable base 18 is fixedly installed on the output end of the mold sleeve driver 13. The movable base 18 is located directly above the mold base 17. The movable base 18 has an installation groove for installing mold sleeve 2 16. A positioning block 181 symmetrical about the center line of the mold sleeve is integrally formed on the movable base 18. The positioning block 181 is inserted into the positioning groove 156 of mold sleeve 2 16 and cooperates with the positioning groove 156. The positioning block 181 is used to insert into the positioning groove 156 of the lower mold sleeve 15 when mold sleeve 15 and mold sleeve 2 16 are closed.

[0043] When the flaring mold sleeve is closed, the convex-concave fit of the protrusion 151 and the concave part 161 enables the mold sleeve 15 and the mold sleeve 2 16 to automatically achieve coaxial alignment when closed. The structure of the positioning groove 156 and the positioning block 181 enables the mold sleeve 15 and the mold sleeve 2 16 to be aligned in the axial position. Thus, automatic alignment is achieved by using the mold closing action, which simplifies the alignment difficulty and improves the alignment accuracy, thereby ensuring the consistency of the flaring process quality, that is, ensuring the stability of the processing quality.

[0044] Mold sleeve 15 and mold base 17, and mold sleeve 2 and movable base 18 are all positioned by slots and then fixedly installed (accommodating slot and installation slot), making the installation of mold sleeve 15 and mold sleeve 2 16 simple and convenient.

[0045] 2. Feeder 2 Combination Figure 1 , Figures 6 to 9 The feeder 2 includes an inclined material rack 21 and a feeding assembly 22. A stop is fixedly installed at the downward-inclined end of the material rack 21 to prevent the pipe 10 from continuing to fall along the inclined structure. At least two discharge rods 212 are fixedly installed above the material rack 21. Each discharge rod 212 includes a height-limiting section and a guide section. The guide section forms a V-shape with the material rack 21. The distance between the height-limiting section and the material rack 21 decreases as it approaches the stop. The minimum distance between the height-limiting section and the material rack 21 allows only one pipe 10 to pass through. The discharge rods 212 allow the pipe 10 moving downwards along the inclined structure of the material rack 21 to gradually form a single layer of pipe 10 under the action of the discharge rods 212. This facilitates the feeding assembly 22 to feed out only a fixed number of pipes 10 at a time, such as one pipe 10 at a time in this embodiment.

[0046] The feeding assembly 22 includes a lifting pusher 221 and a top pusher plate 222. The lifting pusher 221 is fixedly installed, and the top pusher plate 222 is fixed to the output end of the lifting pusher 221. The top pusher plate 222 has an inclined surface 2221 machined on it, and a blocking block 211 is fixed to the downward inclined end of the inclined surface 2221. When the lifting pusher 221 is working, the top pusher plate 222 pushes one pipe 10 upward at a time, transferring the pipe 10 from the material rack 21 to the top pusher plate 222, and then moving it completely along the inclined surface 2221 of the top pusher plate 222 to the outside of the material rack 21 and being blocked by the blocking block 211.

[0047] III. Transfer Support Group and Transfer Unit 4 Combination Figure 7 , Figure 10 and Figure 11 The transfer support group is installed on the frame (the frame is a fixed installation structure, such as the workbench 11 of the flaring machine 1, or the fixed platform 41 of the transferor 4). There is more than one transfer support group. Each transfer support group includes at least two transfer support components. In this embodiment, each transfer support component has a U-shaped or V-shaped support groove. The transfer support component is fixedly or rotatably installed on the frame. The transfer support component is used to support the pipe 10. The transfer support component 3 closest to the feeder 2 is directly opposite the feeding component 22. Specifically, the feeding component 22 is located on the line connecting all the transfer support components of the transfer support group, so that the pipe 10 taken out after the feeding component 22 pushes is caught by the transfer support component 3 after the push plate 222 descends.

[0048] The transferor 4 is located on one side of the output end of the material rack 21. The transferor 4 includes a fixed platform 41, a translation seat 42, a lifter 43, and a gripper 44. The fixed platform 41 is fixedly installed, and the translation seat 42 is slidably connected to the fixed platform 41. The translation seat 42 is driven away from or close to the material rack 21 by a linear drive mechanism such as a cylinder or a hydraulic cylinder.

[0049] The lifting device 43 is fixed on the translation base 42, and the gripper 44 is fixed on the output end of the lifting device 43. In this embodiment, the gripper 44 adopts a pneumatic finger structure. The translation base 42 can drive the gripper 44 to move closer to / away from the feeder 2, while the lifting device 43 controls the lifting and lowering action of the gripper 44. The gripper 44 is used to place the pipe 10 in the flaring die sleeve.

[0050] In this embodiment, there are multiple pairs of grippers 44, each pair having two gripper bodies. Each gripper body is paired with a lifter 43. The line connecting the gripper bodies of the same pair is parallel to the axial direction of the pipe 10. In this embodiment, each gripper body uses an actuating finger. The spacing between adjacent pairs of grippers 44 projected along the moving direction of the translation seat 42 and the spacing L between adjacent transfer support groups are equal. In this embodiment, there are 4 pairs of grippers 44 and 4 sets of transfer support groups. The distance between the left flaring machine 1 and the right flaring machine 1 in the direction of movement of the translation seat 42 is equal to twice L.

[0051] This embodiment also provides an automatic flaring method for the pipe 10, including the following steps: S1. Pipe 10 is sent from the material rack 21 to the transfer support assembly. Specifically, multiple pipes 10 are placed on the material rack 21. The pipes 10 move downward along the inclined structure of the material rack 21 and gradually form a single layer of pipe 10 under the action of the discharge rod 212. Then, the lifting pusher 221 on the feeding assembly 22 is activated, so that the push plate 222 moves upward and lifts the pipe 10 closest to the limit stop to get off the material rack 21. The pushed pipe 10 moves along the inclined surface 2221 and is blocked by the blocking block 211. After that, the lifting pusher 221 drives the push plate 222 to descend. After the push plate 222 descends, it is caught by the transfer support assembly 3.

[0052] S2. Pipe 10 is transferred: First, the translation seat 42 moves closer to the feeder 2, causing all the grippers 44 to move a distance L, so that the pair of grippers 44 closest to the feeder 2 is located below the transfer support group closest to the output end of the feeder 2. Then, the lifter 43 is controlled to rise, and the pipe 10 is lifted by the grippers 44. After that, the grippers 44 are controlled to grab the pipe 10. Since the number of grippers 44 is the same as the number of transfer support groups, each time the lifter 43 rises, it lifts all the pipes 10 on the transfer support groups. After the translation seat 42 moves a distance L in the opposite direction, all the pipes 10 are translated once. Finally, the lifter 43 is controlled to fall again, so that the pipe 10 is placed on the transfer support again.

[0053] During the transfer of pipe 10, since both the left flaring machine 1 and the right flaring machine 1 are directly opposite to the corresponding set of transfer support groups, pipe 10 can fall directly onto the flaring mold after transfer.

[0054] S3. Flaring the pipe 10: Control the flaring die sleeve to close so that the flaring die sleeve restricts the end of the pipe 10 to be flared, and then control the flaring die core 14 to be inserted into the pipe 10 to complete the flaring.
