Description

Technical Field

[0001] This invention relates to the field of pipe processing equipment, and in particular to a short pipe bending processing equipment. Background Technology

[0002] When pipe fittings are processed by bending, flaring, etc., the existing processing technology involves single-process manual processing. The pipe is bent manually on a pipe bending machine, then placed on a flaring machine for double-head flaring, and finally clamped twice on a lathe to flatten and shape both ends. The process is cumbersome, labor costs are high, efficiency is low, and it is not suitable for mass production. Summary of the Invention

[0003] The purpose of this invention is to provide a short pipe bending processing equipment that solves the above-mentioned problems.

[0004] To solve the above-mentioned technical problems, the present invention provides a short pipe bending processing equipment, including a worktable, a pipe bending processing mechanism disposed on the worktable, and a pipe flaring and shaping mechanism disposed on the worktable. The pipe bending processing mechanism includes a bending assembly, a positioning groove disposed on one side of the bending assembly, and a push rod disposed on the side of the positioning groove away from the bending assembly. The push rod can move axially. When the pipe is placed in the positioning groove, the push rod pushes the pipe to the bending assembly for bending processing.

[0005] Furthermore, the pipe bending processing mechanism also includes a front insert mandrel located on the side of the positioning groove near the bending assembly and a rear mandrel located at the end of the push rod. The front insert mandrel can move axially. When the pipe is placed in the positioning groove, the rear mandrel and the front insert mandrel are respectively inserted into the two ends of the pipe.

[0006] Furthermore, a positioning sleeve is provided on the outside of the front insert mandrel, and the front insert mandrel can move axially along the positioning sleeve. The rear mandrel has a ball head at its end. When the rear mandrel is inserted into the pipe fitting, the ball head is located inside the bend of the pipe fitting.

[0007] Furthermore, the pipe bending processing mechanism also includes a sliding seat and a fixed seat that can move laterally along the sliding seat. The positioning sleeve and the front insert mandrel are located on the fixed seat. The sliding seat can rotate along the rotation center axis of the pipe bending processing. The side of the push rod away from the pipe bending assembly is connected to the positioning seat. The positioning seat can move relative to the worktable along the axial direction of the push rod. An elastic element is provided between the push rod and the positioning seat.

[0008] Furthermore, the pipe bending processing mechanism also includes a loading rack located on one side of the positioning groove and a translation component for conveying the pipe. The translation component includes at least two translation assemblies, each including a translation track, a movable translation seat located on the translation track, and a gripper that can move up and down along the translation seat. The gripper in one translation assembly is used to convey the pipe at the loading rack to the positioning groove, and the gripper in the other translation assembly is used to remove the pipe after bending processing from the positioning groove and convey it to a designated position.

[0009] Furthermore, the pipe fitting flaring and shaping mechanism includes a flaring component on the workbench and a shaping component on one side of the flaring component. The flaring component includes a flaring base, a first clamping mold that can be raised and lowered on the upper side of the flaring base, and at least two punches on both sides of the flaring base. When the pipe fitting is clamped and fixed by the flaring base and the first clamping mold, the at least two punches perform flaring processing on both ends of the pipe fitting.

[0010] Furthermore, the flared base has a first placement groove corresponding to the pipe fitting, and the first clamping mold has a second placement groove corresponding to the first placement groove. When the pipe fitting is clamped and fixed by the flared base and the first clamping mold, the pipe fitting is located between the first placement groove and the second placement groove.

[0011] Furthermore, the shaping component includes a shaping base, a second clamping mold disposed on the upper side of the shaping base and adjustable in height, and at least two shaping cutters disposed on both sides of the shaping base. When the pipe is clamped and fixed by the shaping base and the second clamping mold, the at least two shaping cutters shape and cut off both ends of the pipe.

[0012] Furthermore, the shaping base has a third placement groove corresponding to the pipe, and the second clamping mold has a fourth placement groove corresponding to the third placement groove. When the pipe is clamped and fixed by the shaping base and the second clamping mold, the pipe is located between the third placement groove and the fourth placement groove.

[0013] Furthermore, the pipe flaring and shaping mechanism also includes a transverse moving component for conveying the pipe. The transverse moving component includes a transverse moving track, at least three pneumatic gripper seats that are movable on the transverse moving track, pneumatic grippers that are axially telescopic and are provided on the pneumatic gripper seats, and at least two inner support rods provided at the ends of the pneumatic grippers. When the pneumatic grippers convey the pipe, the inner support rods support the pipe from the inside of the pipe end outward.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. The pipe fittings are bent by the pipe bending processing mechanism, which can ensure the accurate processing position of the pipe fittings under the push of the push rod. With the support of the front insert mandrel and the rear mandrel, the bending effect of the pipe fittings is increased.

[0016] 2. By coordinating the pipe bending processing mechanism with the translation component, the feeding and bending processing of pipe fittings can be automated, increasing automation and reducing human error;

[0017] 3. The pipe fitting flaring and shaping mechanism can flare and shape both ends of the pipe fitting, which can improve the efficiency of the pipe fitting flaring and shaping process;

[0018] 4. Through the cooperation of the pipe fitting flaring and shaping mechanism and the transverse moving component, the conveying of pipe fittings and the processing coordination between various processes can be automated, reducing human error and improving overall processing efficiency.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0034] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0035] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0036] like Figure 1-13 The present invention provides a short pipe bending processing equipment, including a workbench 1, a pipe bending processing mechanism 2 disposed on the workbench 1, and a pipe flaring and shaping mechanism 3 disposed on the workbench 1. The pipe bending processing mechanism 2 includes a bending assembly 21, a positioning groove 22 disposed on one side of the bending assembly 21, and a push rod 23 disposed on the side of the positioning groove 22 away from the bending assembly 21. The push rod 23 can move axially. When the pipe 4 is placed in the positioning groove 22, the push rod 23 pushes the pipe 4 to the bending assembly 21 for bending processing.

[0037] When pipe fittings need to be bent, the pipe fitting to be processed is placed in the positioning groove, and then the pipe fitting is pushed to the bending processing position of the bending assembly by the push rod. The bending assembly then performs the bending processing on the pipe fitting to ensure that the position of the pipe fitting is accurate and stable during bending, and to avoid incorrect bending position.

[0038] The pipe bending assembly has a similar structure to existing pipe bending equipment, and the pipe bending process is also the same as that of existing pipe bending equipment, so it will not be described in detail here.

[0039] In one embodiment of this solution, the positioning groove is set in a "V" shape so that when the pipe is placed in the positioning groove, the pipe can be positioned in the groove of the "V" shape by itself. With the push rod pushing the pipe, the position of the pipe during the processing is guaranteed to be accurate.

[0040] Preferably, the pipe bending processing mechanism 2 further includes a front insert mandrel 24 located on the side of the positioning groove 22 near the bending assembly 21 and a rear mandrel 25 located at the end of the push rod 23. The front insert mandrel 24 can move axially. When the pipe 4 is placed in the positioning groove 22, the rear mandrel 25 and the front insert mandrel 24 are respectively inserted into the two ends of the pipe 4.

[0041] Specifically, when the pipe fitting is pushed to the bending position by the push rod, the front insert mandrel is inserted into the pipe fitting from the front end and supports the interior of the front end of the pipe fitting. At the same time, the rear mandrel is inserted into the pipe fitting from the rear end and supports the interior of the rear end of the pipe fitting. The front insert mandrel and the rear mandrel work together to support and protect both ends of the pipe fitting, avoiding problems such as slippage and wrinkles during the pipe bending process.

[0042] Preferably, the front inserting mandrel 24 is fitted with a positioning sleeve 26, and the front inserting mandrel 24 can move axially along the positioning sleeve 26. The rear mandrel 25 has a ball head 27 at its end. When the rear mandrel 25 is inserted into the pipe fitting 4, the ball head 27 is located inside the bend of the pipe fitting 4.

[0043] Specifically, when the push rod moves the pipe fitting to the bend position, the positioning sleeve on one side of the pipe fitting limits its position. After the push rod pushes the pipe fitting against the end of the positioning sleeve, the push rod and the positioning sleeve limit both ends of the pipe fitting, ensuring the accuracy of its processing position. Then, the front insert mandrel moves axially along the positioning sleeve to the front end of the pipe fitting. At the same time, due to the ball head at the end of the rear mandrel, and the ball head being located inside the bend position of the pipe fitting after the rear mandrel is inserted into the pipe fitting, the ball head can support and protect the bend position of the pipe fitting, further increasing the overall stability of the pipe bend.

[0044] Preferably, the pipe bending processing mechanism 2 further includes a sliding seat 28 and a fixed seat 29 that can move laterally along the sliding seat 28. The positioning sleeve 26 and the front insert mandrel 24 are disposed on the fixed seat 29. The sliding seat 28 can rotate along the rotation center axis of the pipe bending processing. The side of the push rod 23 away from the pipe bending assembly 21 is connected to the positioning seat 210. The positioning seat 210 can move relative to the worktable 1 along the axial direction of the push rod 23. An elastic element 211 is provided between the push rod 23 and the positioning seat 210.

[0045] Specifically, during pipe bending, the sliding seat rotates synchronously along the rotation center axis of the bending process. This causes the sliding seat to drive the fixed seat, positioning sleeve, and front insert mandrel to rotate synchronously. As a result, the front insert mandrel can maintain its support effect on the inside of the pipe during bending, while avoiding interference between the front insert mandrel and the pipe bending process. After the pipe bending is completed, the fixed seat moves laterally relative to the sliding seat, causing the front insert mandrel, which is still in the inserted state, to pull the pipe out of the bending assembly by a certain distance. This provides a certain gap for removing the pipe from the bending assembly laterally.

[0046] In addition, due to the positioning seat, when the positioning seat moves axially relative to the worktable along the push rod, the push rod and the rear core rod can be moved axially through the positioning seat, thereby ensuring the accuracy of the pipe position. Furthermore, since there is an elastic element between the push rod and the positioning seat, after the push rod pushes the pipe against the positioning sleeve, the elastic element can buffer the push rod and the positioning seat, avoiding the situation where the pipe or push rod is damaged after being forcibly pushed.

[0047] The sliding base is equipped with a servo motor at its bottom, which drives the sliding base to rotate and ensures that the rotation center of the sliding base is the same as the rotation center axis of the pipe bending process. At the same time, the sliding base is equipped with a cylinder, which is connected to the fixed base. The cylinder drives the fixed base to move laterally and reset relative to the sliding base, so as to ensure the convenience of pipe bending and subsequent removal. The fixed base is also equipped with a cylinder, which is connected to the front insertion mandrel, so that the movement of the front insertion mandrel relative to the positioning sleeve can be driven by the cylinder.

[0048] Specifically, a track and a hydraulic cylinder are provided on one side of the positioning seat. The hydraulic cylinder is connected to the positioning seat and drives the positioning seat to move along the track, so that the positioning seat drives the push rod to move axially. In this solution, the elastic element is a spring.

[0049] Preferably, the pipe bending processing mechanism 2 further includes a loading rack 212 disposed on one side of the positioning groove 22 and a translation component for conveying the pipe 4. The translation component includes at least two translation assemblies, each including a translation track 213, a movable translation seat 214 disposed on the translation track 213, and a gripper 215 that can be raised and lowered along the translation seat 214. The gripper 215 in one translation assembly is used to convey the pipe 4 at the loading rack 212 to the positioning groove 22, and the gripper 215 in the other translation assembly is used to remove the pipe 4 after bending processing from the positioning groove 22 and convey it to a designated position.

[0050] Specifically, each pipe is loaded sequentially to the designated position via the loading rack. Then, the clamp in one of the translation components descends to clamp the pipe and rises while clamped. The pipe is then moved along the translation track to the top of the positioning slot and descends again. At this point, the clamp releases, and the corresponding pipe is placed in the positioning slot to await bending processing.

[0051] Similarly, after the pipe bending process is completed, and the fixed seat drives the front insert mandrel to move laterally, so that the front insert mandrel pulls the pipe from the bending assembly a certain distance, the jaws in another translation assembly lower down and clamp the pipe. Then, they rise, move, and fall in sequence, so that the pipe is clamped to the designated position, waiting for subsequent conveying and processing. At the same time, since the front insert mandrel pulls the pipe from the bending assembly a certain distance, it effectively increases the range of motion of the jaws when clamping the pipe, avoiding interference and wear between parts.

[0052] It is worth mentioning that the movement of the translation seat relative to the translation track, the lifting and lowering of the gripper relative to the translation seat, and the gripping and releasing actions of the gripper itself are all controlled by different cylinders to ensure the accuracy of the translation component during use.

[0053] The structure and operation of the feeding rack are the same as those of the existing feeding rack, and will not be described in detail here.

[0054] In one embodiment of this solution, when the feeding direction of the pipe fittings on the feeding rack in the actual equipment is different from the placement direction of the pipe fittings in the positioning groove, a rotating mechanism can be added to the gripper, and the rotation of the gripper can be controlled by a servo motor, so that after the gripper picks up the pipe fittings from the feeding rack, it can rotate at a certain angle to ensure that the pipe fittings can fall into the positioning groove.

[0055] Preferably, the pipe flaring and shaping mechanism 3 includes a flaring component on the workbench 1 and a shaping component on one side of the flaring component. The flaring component includes a flaring base 31, a first clamping mold 32 that can be raised and lowered and is located on the upper side of the flaring base 31, and at least two punches 33 located on both sides of the flaring base 31. When the pipe 4 is clamped and fixed by the flaring base 31 and the first clamping mold 32, the at least two punches 33 perform flaring processing on both ends of the pipe 4.

[0056] Specifically, when the pipe needs to be flared at the end, the pipe is transported to the flaring base. Then, the first clamping die is lowered so that the flaring base and the first clamping die clamp and fix the pipe. Then, the two punches on both sides of the flaring base move closer to the two ends of the pipe and flare the two ends of the pipe by punching.

[0057] The lifting and lowering of the first clamping die, the approach of the punch to the end of the pipe, and the resetting are all controlled by different hydraulic cylinders.

[0058] It is worth mentioning that the die flaring method and the specific structure of the die in this solution are similar to those of existing dies, and the operating principle is the same.

[0059] Preferably, the flared base 31 has a first placement groove 34 corresponding to the pipe 4, and the first clamping mold 32 has a second placement groove corresponding to the first placement groove 34. When the pipe 4 is clamped and fixed by the flared base 31 and the first clamping mold 32, the pipe 4 is located between the first placement groove 34 and the second placement groove.

[0060] Specifically, when the pipe is placed on the flaring base, the first placement groove limits the pipe to ensure stability during the flaring process and ensures that both ends of the pipe correspond to the two punches. At the same time, the second placement groove, in conjunction with the first clamping mold, further enhances the fixing effect on the pipe after the first placement groove descends.

[0061] Preferably, the shaping component includes a shaping base 35, a second clamping mold 36 disposed on the upper side of the shaping base 35 and adjustable, and at least two shaping cutters 37 disposed on both sides of the shaping base 35. When the tube 4 is clamped and fixed by the shaping base 35 and the second clamping mold 36, the at least two shaping cutters 37 shape and cut off both ends of the tube 4.

[0062] Specifically, after the pipe is bent, both ends of the pipe will be subjected to a certain tensile force, making the ends of the pipe beveled. Therefore, it is necessary to shape and remove the excess pipe ends to ensure the flatness of the pipe ends. When it is necessary to shape and remove the pipe ends, the pipe is transported to the shaping base. Then, the second clamping mold descends and cooperates with the shaping base to clamp and fix the pipe. At the same time, two shaping cutters approach the pipe ends and rotate to shape and cut them, increasing the flatness of the pipe ends.

[0063] The lifting and lowering of the second clamping mold is controlled by a cylinder. The approach and resetting of the shaping tool to the pipe is controlled by a servo motor-driven electric push rod. The rotation of the shaping tool itself is controlled by a motor, so that the shaping tool can stably shape and cut off the end of the pipe.

[0064] It is worth mentioning that the structure and cutting method of the shaping tool are the same as those of existing pipe cutting tools.

[0065] Preferably, the shaping base 35 has a third placement groove 38 corresponding to the tube 4, and the second clamping mold 36 has a fourth placement groove corresponding to the third placement groove 38. When the tube 4 is clamped and fixed by the shaping base 35 and the second clamping mold 36, the tube 4 is located between the third placement groove 38 and the fourth placement groove.

[0066] Specifically, when placing the tube on the shaping base, the tube is positioned using the third and fourth placement slots to ensure the stability and accuracy of the tube's position during the shaping and cutting process.

[0067] Preferably, the pipe flaring and shaping mechanism 3 further includes a transverse moving component for conveying the pipe 4. The transverse moving component includes a transverse moving track 39, at least three pneumatic gripper seats 310 movable on the transverse moving track 39, pneumatic grippers 311 axially extendable on the pneumatic gripper seats 310, and at least two inner support rods 312 at the ends of the pneumatic grippers 311. When the pneumatic grippers 311 convey the pipe 4, the inner support rods 312 support the pipe 4 from the inside of the end of the pipe 4 outward.

[0068] Specifically, after the pipe bending process is completed and the pipe is moved to the designated position by the gripper, one of the pneumatic grippers transports it to the flaring base for flaring. After the pipe is flared, another pneumatic gripper transports it to the shaping base for shaping and cutting. After the pipe is shaped and cut, the last pneumatic gripper transports it to the designated position for unloading. This allows the three pneumatic grippers in the transverse movement component to perform the three processes of picking up, feeding, and unloading simultaneously, increasing the speed and stability of the pipe transport process.

[0069] It is worth mentioning that when the pneumatic gripper moves the pipe, it is controlled by moving the gripper seat along the transverse track. When the pneumatic gripper needs to fix and transport the pipe, the gripper seat first moves to the corresponding position, and then the pneumatic gripper extends relative to the gripper seat, causing the inner support rod to move to one side of the pipe end under the action of the pneumatic gripper. At this time, the gripper seat moves laterally a certain distance towards the pipe, causing the inner support rod to move to the inside of the pipe end. Then, the two inner support rods open outwards, so that the inner support rods support the pipe from the inside of the pipe end outwards, thus completing the fixation of the pipe by the inner support rods and ensuring stability during the transport process.

[0070] The movement of the gripper base relative to the transverse track is controlled by a servo motor in conjunction with an electric track. The extension and retraction of the gripper relative to the gripper base, the opening of the inner support rod, and the resetting are all controlled by different cylinders.

[0071] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
