Description

Technical Field

[0001] The present invention relates to the technical field of pipe bending, and in particular to a pipe bending processing device and a processing method. Background Art

[0002] The pipe is bent using a complete set of bending equipment. The raw material is usually a straight pipe cut into sections in advance. It is placed in the corresponding mold for bending to complete the processing. Common pipe bends can be completed using this step, but some pipe bends require processing of the two ports after bending to shape the ports to the corresponding installation positions.

[0003] The existing pipe bending machines usually do not have the function of processing this type of bent pipe. Therefore, the processing of this type of bent pipe usually requires secondary processing after the bending is completed, which requires additional processing steps. The transportation between different processes is also relatively inconvenient, and the overall processing efficiency is low. Summary of the Invention

[0004] In order to solve the problem that the pipe bending machines in the existing technology usually do not have the function of processing this type of bent pipe, the processing of this type of bent pipe usually requires secondary processing after the bending is completed, and additional processes are required for processing. The transportation between different processes is also relatively inconvenient, and the overall processing efficiency is low. This application provides a pipe bending processing equipment, and the specific plan is as follows.

[0005] A pipe bending processing equipment includes a feeding mechanism, a bending mechanism, a first processing mechanism, a second processing mechanism, a discharging mechanism and a transfer mechanism. The feeding mechanism, the bending mechanism, the first processing mechanism, the second processing mechanism and the discharging mechanism are all arranged circumferentially around the transfer mechanism. The transfer mechanism is used to clamp the workpiece for transfer. The bending mechanism is used to bend straight pipes. The first processing mechanism is used to process one end of the bent pipe, and the second processing mechanism is used to process the other end of the bent pipe. The discharging mechanism is used to deliver the product.

[0006] By adopting the above technical solution, the entire process of straight tube loading, bending, end processing and discharge can be automated. The surround layout cooperates with the transfer mechanism to clamp the workpiece and transfer it. The straight tube raw material can be bent and both ends can be processed into the required shape according to the set steps, which can improve processing efficiency and production continuity, thereby improving overall processing efficiency.

[0007] Optionally, the transfer mechanism includes a three-axis robotic arm, which can rotate and move in the horizontal direction and in the vertical direction. A double-headed clamp is provided at the end of the three-axis robotic arm, and the double-headed clamp includes a clamping rod and a clamping head. The middle part of the clamping rod is rotatably connected to the top end of the three-axis robotic arm, and the clamping head is provided at both ends of the clamping rod. The clamping heads at both ends of the clamping rod can clamp the workpiece at the same time.

[0008] By adopting the above technical solution, a double-headed clamp is provided at the end of the three-axis robotic arm, and the middle part of the clamping rod is rotatably connected to the top of the three-axis robotic arm. The clamping heads at both ends can clamp the workpiece at the same time. When feeding the workpiece, it is only necessary to rotate the clamping rod to send out the workpieces clamped at both ends separately, thereby improving the workpiece transfer efficiency, realizing the transfer of multiple workpieces at a time, and speeding up the entire processing process.

[0009] Optionally, the feeding mechanism includes a step loader and a linear feeding mechanism, a feeding rack is slidingly provided on the linear feeding mechanism, the feeding rack can move along the linear feeding mechanism, a feeding clamp is rotatably provided on the feeding rack, and a feeding chuck is provided at both ends of the feeding clamp, and the loading chuck is used to clamp the workpiece at the step loader.

[0010] By adopting the above technical solution, the stepped loader is convenient for providing straight pipe raw materials. The linear feeding mechanism cooperates with the feeding rack to realize the linear movement of the feeding jaws. The rotation setting of the feeding jaws and the feeding chucks at both ends can clamp two raw materials at the same time waiting for processing, thereby improving the feeding efficiency of the pipe bending processing equipment.

[0011] Optionally, the bending mechanism includes a bending table, a fixed mold and a bending mold are provided on the bending table, and clamping grooves are provided on the fixed mold and the bending mold corresponding to the shape of the workpiece. A clamping drive component is provided on the bending table corresponding to the fixed mold, and the clamping drive component can push the fixed mold to clamp the workpiece from both sides. The bending mold is only provided on one side of the workpiece and abuts against the workpiece. A bending drive component is provided on the bending table corresponding to the bending mold, and the bending drive component can drive the bending mold to rotate in the horizontal direction, and when the bending mold rotates, it can abut and push the workpiece to bend.

[0012] By adopting the above technical solution, the bending mechanism pushes the fixed mold to clamp the workpiece from both sides through the clamping grooves on the fixed mold and the bending mold in conjunction with the clamping drive. The workpiece can be clamped on both sides, and the bending drive drives the bending mold to rotate horizontally to push the workpiece to bend, thereby realizing precise bending processing of the straight tube.

[0013] Optionally, the bending mechanism further includes a pushing rod, which is arranged at a position corresponding to the fixed mold and can extend into the clamping groove, and the pushing rod is used to push the workpiece in the fixed mold toward the bending mold.

[0014] By adopting the above technical solution, the push rod is set corresponding to the fixed mold and can extend into the clamping groove, which can push the workpiece in the fixed mold toward the bending mold. Since the workpiece needs to move during bending in order to bend according to the required arc, the bending mold can be aligned with different positions that need to be bent by pushing the push rod, so that the workpiece can be bent more accurately and efficiently, thereby improving the quality and efficiency of the pipe bending process.

[0015] Optionally, the bending mechanism is further provided with a turntable, which is arranged corresponding to the shape of the workpiece after bending, and is used to place the bent workpiece.

[0016] By adopting the above technical solution, the turntable is used to set up the shape of the workpiece after bending, so that the bent workpiece can be temporarily placed. This is more convenient when multiple workpieces are transported at the same time, and it is convenient for the subsequent transfer mechanism to clamp the workpiece and perform subsequent processing operations on both ends in sequence, which is conducive to improving processing efficiency.

[0017] Optionally, the first processing mechanism includes a first processing table, on which a first clamping seat and a first driving member are provided, the first driving member is used to drive the first clamping seat to clamp the workpiece on the upper and lower sides of the workpiece, and when the first clamping seat clamps the workpiece, one end of the workpiece extends out of the first clamping seat. The first processing table also includes a first processing seat and a first processing linear mechanism, the first processing linear mechanism is used to drive the first processing seat to move along the horizontal direction of the first processing table, and a plurality of processing tool heads are provided on the first processing seat, and the processing tool heads are used to process the end of the workpiece on the first clamping seat.

[0018] By adopting the above technical solution, the first processing mechanism can process one end of the bent pipe, the first driving member drives the first clamping seat to stably clamp the workpiece from the upper and lower sides, so that one end of the workpiece is extended for subsequent processing, and the first processing linear mechanism drives the first processing seat to move in the horizontal direction, so that the processing head can accurately and flexibly process the end of the workpiece.

[0019] Optionally, a first positioning cylinder is further provided on the first processing table, and a piston rod of the first positioning cylinder is provided corresponding to the first clamping seat, and the piston rod of the first positioning cylinder can extend into the workpiece and abut against the inner wall of the workpiece.

[0020] By adopting the above technical solution, a first positioning cylinder is provided on the first processing table, and its piston rod can extend into the workpiece and abut against the inner wall, thereby positioning the workpiece and reducing the loosening of the workpiece during processing. The positioning accuracy and stability of the first processing mechanism when processing the end of the workpiece can be improved, thereby ensuring the processing quality.

[0021] Optionally, the second processing mechanism includes a second processing table, which is provided with a second clamping seat and a second driving member with the same structure as those on the first processing table. The second driving member is used to drive the second clamping seat to clamp the workpiece at the upper and lower sides of the workpiece. When the second clamping seat clamps the workpiece, one end of the workpiece extends out of the second clamping seat. The second processing table is also provided with a second processing seat and a second processing linear mechanism. The second processing linear mechanism is used to drive the second processing seat to move along the horizontal direction of the first processing table. A plurality of processing tool heads are provided on the second processing seat, and the processing tool heads are used to process the end of the workpiece on the second clamping seat. The second processing seat is also provided with a second positioning cylinder. The piston rod of the second positioning cylinder is arranged corresponding to the second clamping seat, and the piston rod of the second positioning rod can extend into the workpiece and abut against the inner wall of the workpiece.

[0022] By adopting the above technical solution, the second processing mechanism can process the product in the same manner as the first processing mechanism, thereby processing the unprocessed end of the workpiece, thereby completing the processing of both ends.

[0023] The present application provides a pipe bending processing equipment method, including the pipe bending processing equipment according to any one of claims 1 to 9, using the following method: a. The feeding mechanism feeds straight pipe raw materials and can simultaneously hold two raw materials for processing; b. The bending mechanism processes the straight tube, places the first processed straight tube into the transfer table, and at the same time, the second raw material can be fed in for processing; c. The transfer mechanism clamps the two processed raw materials to the first processing mechanism at the same time. After the first raw material is processed, the first raw material is taken out and the second raw material is put in. d. The transfer mechanism sends the first processed raw material to the second processing mechanism, and then waits for the second raw material to be processed; e. The transfer mechanism takes out the first processed raw material from the second processing mechanism to the discharging mechanism, and takes out the third raw material from the transfer table; f. The transfer mechanism takes out the second raw material from the first processing mechanism and puts in the third raw material; h. Repeat steps df to achieve continuous processing.

[0024] By adopting the above technical solution, using the pipe bending processing equipment including a loading mechanism, a bending mechanism, a first processing mechanism, a second processing mechanism, a discharging mechanism and a transfer mechanism, and operating according to a specific method, two raw materials can be clamped at the same time waiting for processing during loading, and the first processed straight pipe can be placed on the transfer table and the second raw material can be fed in during bending, which can improve the raw material transportation efficiency; the transfer mechanism can clamp two completed raw materials to the first processing mechanism at the same time, and replace one raw material after processing, and can also transfer the raw materials between the mechanisms in an orderly manner, realizing multi-station alternating processing and improving production efficiency; repeating the processing steps can achieve continuous processing, ensure production continuity, and improve production capacity.

[0025] In summary, this application has at least the following beneficial effects: The present application solves the problem that the pipe bending machines under the existing technology usually do not have the function of processing this type of bent pipe. Therefore, the processing of this type of bent pipe usually requires secondary processing after the bending is completed, which requires additional processes, and the transportation between different processes is also relatively inconvenient, resulting in low overall processing efficiency. The present application sets up multiple mechanisms and transfers the workpiece through a transfer mechanism, which can realize the bending of the workpiece, processing of both ends and discharge in sequence, thereby improving the overall processing efficiency of the bent pipe.

[0030] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0031] Example 1 A pipe bending processing equipment, such as Figure 1 and Figure 2 As shown, it includes a feeding mechanism 1, a bending mechanism 2, a first processing mechanism 3, a second processing mechanism 4, a discharging mechanism 5 and a transfer mechanism 6. The feeding mechanism 1, the bending mechanism 2, the first processing mechanism 3, the second processing mechanism 4, and the discharging mechanism 5 are all arranged circumferentially around the transfer mechanism 6.

In specific implementation, the raw material is a straight tube that has been cut and fed from the feeding mechanism 1. It is first bent into the desired curved tube shape by the bending mechanism 2. After the curved tube is processed at one end by the first processing mechanism 3, it is processed at the second section by the second processing mechanism 4. The overall processing is completed, and then the material can be discharged. The discharging mechanism 5 uses a conveyor belt for transportation.

[0032] like Figure 1 and Figure 2 As shown, the transfer mechanism 6 includes a three-axis robotic arm 61, which can rotate and move in the horizontal direction and in the vertical direction. A double-headed clamp 62 is provided at the end of the three-axis robotic arm 61. The double-headed clamp 62 includes a clamping rod 621 and a clamping head 622. The middle part of the clamping rod 621 is rotatably connected to the top of the three-axis robotic arm 61. The clamping heads 622 are provided at both ends of the clamping rod 621. The clamping heads 622 at both ends of the clamping rod 621 can clamp the workpiece at the same time. In specific implementation, the three-axis robotic arm 61 can establish a rectangular coordinate system in three-dimensional space. The three-axis robotic arm 61 can accurately transport the workpiece within the established rectangular coordinate system, and the double-headed clamp 62 can align the clamping heads 622 at both ends after rotation, so that two groups of workpieces can be transported at the same time, further improving processing efficiency. The specific clamping method of the double-headed clamp is similar to the clamping method in the prior art. It can be clamped from the outside to the inside or pushed from the inside to the outside to form friction to achieve clamping.

[0033] like Figure 1 and Figure 2As shown, the feeding mechanism 1 includes a step loader 11 and a feeding linear mechanism 12. A feeding frame is slidably provided on the feeding linear mechanism 12, and the feeding frame can move along the feeding linear mechanism 12. A feeding clamp 121 is rotatably provided on the feeding frame. Both ends of the feeding clamp 121 are provided with a feeding chuck 122, and the feeding chuck 122 is used to clamp the workpiece at the step loader 11. In a specific implementation, the feeding chuck 122 at one end of the feeding clamp 121 corresponds to the shape of a straight tube and is mainly used to clamp straight tubular workpieces, while the feeding chuck 122 at the other end of the feeding clamp 121 corresponds to the bent workpiece, and can clamp both straight tubes and bent tubes, and can also have the effect of feeding bent workpieces.

[0034] like Figure 1 and Figure 2 As shown, the bending mechanism 2 includes a bending table 21, on which a fixed die 22 and a bending die 23 are provided. A clamping groove 231 is provided on each of the fixed die 22 and the bending die 23 corresponding to the shape of the workpiece. A clamping drive is provided on the bending table 21 corresponding to the fixed die 22. The clamping drive can push the fixed die 22 to clamp the workpiece from both sides. The bending die 23 is only provided on one side of the workpiece and abuts against the workpiece. A bending drive is provided on the bending table 21 corresponding to the bending die 23. The bending drive can drive the bending die 23 to rotate in the horizontal direction. When the bending die 23 rotates, it can abut and push the workpiece to bend. The bending mechanism 2 also includes a drive 25. The drive 25 is provided in the position corresponding to the fixed die 22 and can extend into the clamping groove 231. The drive 25 is used to push the workpiece in the fixed die 22 toward the bending die 23. During specific implementation, the clamping drive member adopts a cylinder. One side of the fixed mold 22 is fixed, and the mold on the other side can move horizontally toward the fixed mold under the drive of the cylinder to clamp the unprocessed workpiece, and the bending mold 23 is arranged on one side of the workpiece. The bending drive member is rotatably arranged on the lower side of the fixed mold 22 and rotates around the fixed mold 22. During the rotation process, the workpiece can be pressed from one side to achieve bending, and the drive member 25 can continuously push the workpiece to move during the bending process, so that all positions of the workpiece can be bent. In this embodiment, a groove is provided on a fixed part of the fixed mold 22 for the bent workpiece to be embedded, further improving the bending effect.

[0035] like Figure 1 and Figure 2 As shown, the bending mechanism 2 is also provided with a transfer table 24. The transfer table 24 is configured to correspond to the shape of the bent workpiece and is used to place the bent workpiece. In specific implementation, the transfer table 24 is positioned within the range within which the loading clamp 121 can move. The loading clamp 121 can then clamp the product onto the transfer table 24 and wait for the transfer mechanism 6 to transfer the product.

[0036] like Figure 1 and Figure 2 As shown, the first processing mechanism 3 includes a first processing table 31, on which is provided a first clamping seat 32 and a first driving member 33.

The first processing table 31 is also provided with a first processing seat 34 and a first processing linear mechanism 35. The first processing linear mechanism 35 is used to drive the first processing seat 34 to move horizontally along the first processing table 31. The first processing seat 34 is provided with a plurality of processing heads 341, which are used to process the end of the workpiece on the first clamping seat 32. The first processing table 31 is also provided with a first positioning cylinder 36. The piston rod of the first positioning cylinder 36 is provided corresponding to the first clamping seat 32 and can extend into the workpiece to abut the inner wall of the workpiece. During specific implementation, the first positioning cylinder 36 needs to extend into the workpiece to limit the deviation of the workpiece and improve the accuracy during processing, and the processing head 341 needs to be selected according to the actual processing, such as a grinding head, an expansion head, etc. When the bent pipe needs to be processed into a corresponding shape, a corresponding head needs to be selected.

[0037] like Figure 1 and Figure 2 As shown, the second processing mechanism 4 includes a second processing table 41, and the second processing table 41 is provided with a second clamping seat 42 and a second driving member 43 with the same structure as those on the first processing table 31. The second driving member 43 is used to drive the second clamping seat 42 to clamp the workpiece at the upper and lower sides of the workpiece. When the second clamping seat 42 clamps the workpiece, one end of the workpiece extends out of the second clamping seat 42. The second processing table 41 is also provided with a second processing seat 44 and a second processing linear mechanism 45. The second processing linear mechanism 45 is used to drive the second processing seat 44 to move along the horizontal direction of the first processing table 31.

The second processing seat 44 is also provided with a second positioning cylinder 46. The piston rod of the second positioning cylinder 46 is arranged corresponding to the second clamping seat 42, and the piston rod of the second positioning rod can extend into the workpiece and abut against the inner wall of the workpiece. In specific implementation, the overall process of the second processing mechanism 4 is basically the same as that of the first processing mechanism 3, but the two ends of the elbow are processed separately, and the two ends of the elbow are exactly the same. In other embodiments, different cutter heads can also be used to process different shapes at the two ends of the elbow, which is determined according to specific production requirements.

[0038] This embodiment also provides a pipe bending processing equipment method, characterized in that it includes any pipe bending processing equipment according to claims 1-9, and adopts the following method: a. The feeding mechanism 1 feeds straight pipe raw materials and can simultaneously hold two raw materials for processing; b. The bending mechanism 2 processes the straight tube and places the first processed straight tube into the transfer table 24, while the second raw material can be fed in for processing; c. The transfer mechanism 6 simultaneously clamps the two processed raw materials to the first processing mechanism 3, waits for the first raw material to be processed, takes out the first raw material and puts the second raw material in; d. The transfer mechanism 6 delivers the first raw material that has been processed to the second processing mechanism 4, and then waits for the second raw material to be processed; e. The transfer mechanism 6 takes out the first processed raw material from the second processing mechanism 4 to the discharging mechanism 5, and takes out the third raw material from the transfer table 24; f. The transfer mechanism 6 takes out the second raw material from the first processing mechanism 3 and puts the third raw material into it; h. Repeat steps df to achieve continuous processing.

[0039] Working principle: The straight pipe is processed through multiple steps and transferred through the transfer mechanism 6 between the processing steps to complete the entire processing process, thereby improving the processing efficiency and processing accuracy.

[0040] Example 2 like Figure 3 As shown, the main difference between the second embodiment and the first embodiment is that the fixed mold 22 of the second embodiment is provided with an embedding groove 221, and a plurality of guide wheels 222 are provided in the embedding groove 221. A return spring 223 is provided between the guide wheels 222 and the groove wall of the embedding groove 221. The return spring 223 has a tendency to pull the guide wheels 222 toward the embedding groove 221. The driving member 25 is provided with an electromagnet block. In a specific implementation, the guide wheels 222 are made of metal, and the electromagnet block on the driving member 25 can attract the workpiece. The workpiece can have a certain degree of magnetism. At this time, the workpiece can suck the guide wheels 222 out of the guide groove. At this time, the guide wheels 222 are in contact with the workpiece, which can reduce friction and make the pushing process smoother.

[0041] Working principle: The basic working principle is the same as that of embodiment 1, but a guide wheel 222 is added to the fixed mold 22 to improve the pushing effect, thereby improving the smoothness of friction when pushing is required and further improving the bending effect.

[0042] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.

The transfer mechanism (6) delivers the first raw material that has been processed to the second processing mechanism (4), and then waits for the second raw material to be processed; e. The transfer mechanism (6) takes out the first raw material that has been processed from the second processing mechanism (4) to the discharging mechanism (5), and takes out the third raw material from the transfer table (24); f. The transfer mechanism (6) takes out the second raw material from the first processing mechanism (3) and puts in the third raw material; h. Repeat steps df to achieve continuous processing.
