Description

Technical Field

[0001] This invention relates to the field of pipe processing technology, and in particular to a pipe chamfering and punching machine. Background Technology

[0002] Currently, pipe punching equipment is generally used to automatically punch pipes to be processed. It includes a pipe transport mechanism and a punching mechanism. The pipe transport mechanism is used to transport the pipes to the punching station and the discharge station in sequence, while the punching mechanism is used to punch one or both ends of the pipe.

[0003] The pipes to be processed are generally obtained by cutting long pipes to a specified length, and the ends of the cut pipes usually have burrs. To prevent these burrs from scratching operators during subsequent assembly, handling, or use, and to improve assembly efficiency, the pipes are typically rounded manually before and after automated punching. This creates a smooth transition surface at both ends, achieving deburring and providing assembly guidance, thus improving worker safety and assembly efficiency. However, this manual method results in a heavy workload, reduced production efficiency, and a high defect rate due to human error. Therefore, there is an urgent need for automated equipment that can automatically round the corners and punch the pipes. Summary of the Invention

[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] like Figures 1 to 4 As shown in the figure, a specific embodiment of the present invention provides a pipe chamfering and punching machine, including a machine base 1 and a feeding mechanism 2, a rounding mechanism 3, a processing mechanism 4, a conveying mechanism 5, and a discharge hopper 11 disposed on the machine base 1. The feeding mechanism 2 is used to transport at least one pipe to be processed to the conveying station to realize automatic feeding. The conveying mechanism 5 includes multiple gripper assemblies 51, each gripper assembly 51 is used to grip at least one pipe. The conveying mechanism 5 is used to sequentially transport at least one pipe at the conveying station to the rounding mechanism 3, the processing mechanism 4, and the discharge hopper 11 to realize automatic and orderly conveying of pipes and improve pipe conveying efficiency. The rounding mechanism 3 is used to align and correct at least one pipe to ensure that each pipe is neatly placed and centered in its respective workstation. Then, the rounding mechanism 3 and the processing mechanism 4 sequentially round the ends of the pipe and punch holes to meet the processing requirements of pipe production. The entire pipe production process requires no manual intervention, effectively realizing automated and orderly pipe production, thereby improving pipe handling efficiency, pipe processing accuracy, and production safety, ultimately enhancing pipe production efficiency and quality. Furthermore, this invention further improves pipe production efficiency by simultaneously automating the handling, rounding, and punching of multiple pipes.

[0019] Specifically, the machine base 1 is provided with a workbench 12, and the front and rear sides of the workbench 12 are respectively provided with a feeding mechanism 2 and a discharge hopper 11; the rounding mechanism 3 includes rounding components 31 respectively provided on the left and right sides of the workbench 12, and the rounding components 31 on both sides are used to align and correct and round the corners of at least one pipe; the processing mechanism 4 includes processing components 41 provided on the left and right sides of the workbench 12, and the processing components 41 on both sides are used to punch at least one end of at least one pipe.

[0020] The workbench 12 is also equipped with a width adjustment mechanism 6, which is connected to the rounding mechanism 3 and the processing mechanism 4 respectively. It is used to drive the rounding components 31 and the processing components 41 on both sides to move closer or further apart, so as to perform rounding and punching treatment on both ends of pipes of different lengths, meet the processing needs of pipes of different lengths, and has a wide range of applications and high practicality.

[0021] The width adjustment mechanism 6 includes a first width adjustment mechanism 61 and a second width adjustment mechanism 62. The first width adjustment mechanism 61 is connected to the first sliding seats 121 on the left and right sides of the worktable 12. The bottom of the first sliding seats 121 is embedded in the first slide rail 122 on the worktable 12. The first sliding seats 121 are equipped with rounded corner components 31. The first width adjustment mechanism 61 is used to drive the first sliding seats 121 on both sides to move closer or further apart, so that the rounded corner components 31 on both sides can move closer or further apart. When aligning and rounding the corners of the pipe, the rounded corner components 31 on both sides can be driven to move closer to the pipe so that the two ends of the pipe can be inserted into the rounded corner components 31 to achieve pipe alignment and rounded corner processing. After that, the rounded corner components 31 on both sides are driven to move further apart so that the conveying mechanism 5 can transport the pipe to the next work station.

[0022] The second width adjustment mechanism 62 is connected to the second sliding seats 123 on the left and right sides of the worktable 12. The bottom of the second sliding seat 123 is embedded in the second slide rail 124 on the worktable 12. The second sliding seat 123 is provided with a processing component 41, which includes at least one punching device 411. The punching device 411 can punch at least one pipe. The second width adjustment mechanism 62 is used to drive the second sliding seats 123 on both sides to move closer or further apart, so that the processing components 41 on both sides can move closer or further apart. When punching the pipe, the processing components 41 on both sides can be driven to move closer to the pipe so that both ends of the pipe can be inserted into the processing components 41 to realize the pipe punching process. After that, the processing components 41 on both sides are driven to move further apart so that the conveying mechanism 5 can transport the pipe to the next work station.

[0023] In other embodiments, the processing component 41 may also include at least one punching device 411 and at least one pipe flipping device, which is used to rotate the pipe to a specified angle position, so as to facilitate the subsequent punching device 411 to punch the pipe at the specified angle position at both ends to meet the actual pipe processing requirements.

[0024] Furthermore, such as Figures 2 to 5As shown, the first width adjustment mechanism 61 is a semi-concealed width adjustment mechanism 6. The semi-concealed width adjustment mechanism 6 includes a first drive motor 611, a first coupling 612, a first lead screw 613, and a first bearing fixing seat 614 connected in sequence. The first drive motor 611 is installed on the outside of the worktable 12. The worktable 12 has first openings 125 on the left and right sides respectively. The first openings 125 are located below the first sliding seat 121. The first coupling 612, the first lead screw 613, and the first bearing fixing seat 614 are all located below the worktable 12 and on one side of the first opening 125. The two ends of the first lead screw 613 are respectively nested with first lead screw connecting seats 615. One end of the first lead screw connecting seat 615 is fixedly connected to the first sliding seat 121 through the corresponding first opening 125. When the first drive motor 611 drives the first lead screw 613 to rotate, it will drive the first lead screw connecting seats 615 located on the left and right sides to move synchronously. The first lead screw connecting seats 615 on both sides and the rounded corner components 31 on them can move closer to each other or further away from each other, so as to align and correct pipes of different lengths and perform rounded corner treatment.

[0025] When the ends of the pipe are rounded, the waste generated can be dropped into the waste trough 13 of the machine 1 through the first port 125 to collect the waste and avoid the waste being pushed onto the workbench 12, which would affect the normal operation of the equipment and reduce the cleanliness of the equipment.

[0026] Furthermore, the second width adjustment mechanism 62 is a fully concealed width adjustment mechanism 6, which includes a second drive motor 621, a second coupling 622, a synchronous belt drive assembly 623, a second lead screw 624, and a second bearing fixing seat 625, all disposed under the worktable 12. Second openings 126 are also provided on the left and right sides of the worktable 12, located below the second sliding seat 123. The second drive motor 621 is located below the discharge station of the worktable 12. The second drive motor 621 is connected to the driving wheel of the synchronous belt drive assembly 623 via the second coupling 622. Both ends of the driven wheel of the synchronous belt drive assembly 623 are respectively connected to one end of the second lead screw 624, and the other end of the second lead screw 624 is connected to the second bearing fixing seat 625 located at the edge of the worktable 12. A second lead screw connecting seat 626 is nested on the second lead screw 624, and one end of the second lead screw connecting seat 626 is fixedly connected to the second sliding seat 123. When the second drive motor 621 drives the synchronous belt transmission assembly 623 to rotate, the second lead screw 624 will drive the second lead screw connecting seats 626 on both sides to move synchronously. The first lead screw connecting seats 615 on both sides and the processing components 41 on them can move closer or further apart to punch pipes of different lengths.

[0027] It should be noted that the synchronous belt drive assembly 623 includes a driving pulley, at least one driven pulley, and at least one synchronous belt. The number of driven pulleys and synchronous belts is the same as the number of processing stations in the processing assembly 41. For example, if the processing assembly 41 has three punching stations, then there are three driven pulleys and three synchronous belts. The driving pulley is connected to the first driven pulley via the first synchronous belt. The first driven pulley is also connected to the second driven pulley via the second synchronous belt. The second driven pulley is connected to the third driven pulley via the third synchronous belt. Each driven pulley has a corresponding second lead screw 624 and the above-mentioned matching structure connected to the second lead screw 624 at both ends. Thus, a drive motor drives multiple driven pulleys and processing devices on multiple processing stations to move closer or further apart synchronously, realizing multi-punching and width adjustment functions, and has a wide range of applications.

[0028] The semi-concealed width adjustment mechanism 6 and the fully concealed width adjustment mechanism 6 are both located within the limited space of the machine base 1, concealing most or all of the structure under the workbench 12 or inside the machine base 1 to achieve a compact overall structure, improve the simplicity and aesthetics of the overall equipment, and reduce external space occupation. Furthermore, when rounding or punching the ends of the pipe, the generated waste material can be discharged into the waste trough 13 of the machine base 1 through the corresponding first port 125 or second port 126 to achieve waste collection, effectively preventing waste from being pushed onto the workbench 12, affecting the normal operation of the equipment, and reducing the cleanliness of the equipment.

[0029] Secondly, to prevent waste material from falling onto the second lead screw 624 and the connection structure between the second lead screw 624 and the second lead screw connecting seat 626, thus affecting the relative movement of the second lead screw connecting seat 626 on the second lead screw 624 and consequently affecting the width adjustment function of the second sliding seat 123 and the processing assembly 41, the following measures are taken: Figure 3 and 5 As shown, a baffle plate 627 is provided on the upper part of the end of the second lead screw connecting seat 626 away from the second bearing fixing seat 625. The second lead screw 624 and the baffle plate 627 are both located below the second through-hole 126, and the baffle plate is located above the second lead screw 624. When punching holes at both ends of the pipe, the waste material falling from both ends of the pipe will fall onto the baffle plate 627 through the second through-hole 126, and then fall into the waste trough 13 below through the edges of the baffle plate. The baffle plate 627 can protect the second lead screw 624 and the connection structure between the second lead screw 624 and the second lead screw 624 seat, ensuring that the second lead screw connecting seat 626 can move stably on the second lead screw 624, thereby ensuring the stable operation of the width adjustment function of the second sliding seat 123 and the processing component 41, and improving the working stability of the equipment.

[0030] Furthermore, such as Figure 1 , Figure 2 , Figure 4and Figure 5 As shown, the rounded corner assembly 31 includes a correction frame 311 and a rounded corner device 312 arranged sequentially along the transport direction of the transport mechanism 5. The correction frame 311 is fixedly connected to the rounded corner device 312 via a mounting plate. At least one correction tube 313 is provided at the end of the correction frame 311 facing the transport mechanism 5, and the correction tube 313 is provided with a correction groove 314. The rounded corner devices 312 located on both sides are used to round the ends of the corrected pipe. In actual use, when the pipe is located at the transport station, the correction frames 311 on both sides can move towards the pipe synchronously under the drive of the width adjustment mechanism 6. Regardless of whether the pipe is located in the exact middle between the two correction frames 311, the correction grooves 314 of the correction tubes 313 on both sides will contact and abut with any end or both ends of the pipe to ensure that the pipe is in the exact middle position and that the placement position of each pipe is aligned and corrected. Next, the conveying mechanism 5 moves the pipe to the next workstation, so that the rounding devices 312 on both sides can accurately and synchronously round the ends of the pipe, and the processing components 41 on both sides can synchronously punch holes at the designated positions at both ends of the pipe, thereby improving the accuracy and quality of pipe processing. Moreover, the conveying mechanism 5 and the rounding devices 312 can automatically feed, round, and discharge the pipe, eliminating the need for manual intervention in the production process. This reduces the workload of personnel and improves their safety, thereby enhancing the production safety of the equipment and the processing stability of the pipe.

[0031] The diameter of the alignment groove 314 gradually decreases from the outside to the inside, forming a guide flared opening. This guide flared opening guides the pipe, causing it to abut against the inner wall of the alignment groove 314, thus pushing the pipe to the center position and achieving pipe alignment and correction. Furthermore, the guide flared opening can achieve alignment and correction for pipes of different diameters; simply requiring the diameter of the guide flared opening to be larger than the diameter of the pipe makes it widely applicable and highly practical.

[0032] Furthermore, the rounding device 312 includes a housing 315, a motor drive device 316 mounted outside the housing 315, a gear linkage assembly and at least one driven shaft 317 mounted inside the housing 315; the gear linkage assembly includes a driving wheel and at least one driven wheel, with the driving wheel and driven wheel meshing together. The drive shaft of the motor drive device 316 passes through the housing wall of the housing 315 and is connected to the driving wheel, and the driven wheel of the gear linkage assembly is connected to one end of the driven shaft 317, with a chamfering scraper 318 provided at the other end of the driven shaft 317; when the motor drive device 316 drives the driving wheel and driven wheel to rotate, it drives the driven shaft 317 to rotate, thereby causing the chamfering scraper 318 to rotate and perform rounding treatment on the end of the pipe.

[0033] The housing 315 has at least one through hole 3151 at one end facing the conveying mechanism 5. One end of the tube passes through the through hole 3151 and contacts the chamfering scraper 318. In actual use, both ends of the tube are inserted into the housing 315 through the through holes 3151 on both sides of the housing 315, so that the two ends of the tube contact the chamfering scraper 318 respectively, realizing automatic rounding of the tube without manual intervention. The operation is simple and convenient, so that the two ends of the tube form a smooth transition surface, realizing the deburring effect and assembly guidance, thereby improving the work safety and assembly efficiency of subsequent personnel.

[0034] Secondly, a waste outlet 3152 is provided at the bottom of the end of the housing 315 facing the conveying mechanism 5. The waste outlet 3152 is used to discharge the waste generated when the pipe is rounded, so as to avoid the waste from accumulating in the housing 315 during long-term use, which would affect the stable operation of the pipe's rounding operation.

[0035] To achieve automated handling of pipes, such as Figure 1 , Figure 3 and Figure 4 As shown, the conveying mechanism 5 includes a horizontal displacement device, a vertical displacement device, and a conveying plate 52. The horizontal displacement device is connected to the vertical displacement device, and the vertical displacement device is connected to the conveying plate 52. Multiple gripper assemblies 51 are spaced apart on the conveying plate 52. In actual use, the horizontal displacement device can drive the vertical displacement device and the conveying plate 52 to move back and forth. The vertical displacement device can further drive the conveying plate 52 to move up and down. Thus, the gripper assemblies 51 on the conveying plate 52 can drive the gripped pipe to move back and forth and up and down, realizing the conveying work of the pipe and ensuring that the pipe is discharged after being processed by all stations.

[0036] It should be noted that both the horizontal displacement device and the vertical displacement device are existing technologies. They are used to perform horizontal and vertical movement functions, and their specific structures and working principles will not be described in detail here.

[0037] The rounding mechanism 3 and the processing mechanism 4 are both equipped with pipe clamping components 7. The pipe clamping components 7 are located below the conveying mechanism 5 and are used to clamp the pipe. When the gripper assembly 51 on the conveying mechanism 5 moves the pipe to the corresponding station, the pipe will be placed on the pipe clamping component 7, which will clamp the pipe. This allows the rounding devices 312 on both sides or the processing components 41 on both sides to move closer to the fixed pipe via the width adjustment mechanism 6, thereby rounding or punching the ends of the pipe. This prevents the pipe from shaking during processing, which would affect the processing quality of the pipe and improve the pipe production quality of the equipment.

[0038] Furthermore, such as Figure 3 , Figure 4 and Figure 6 As shown, both the clamping assembly 51 and the pipe clamping assembly 7 include a first push rod device 71, a fixed clamping plate 72, and a movable clamping plate 73. Fixed clamping portions 74 are provided on both the left and right sides of the fixed clamping plate 72, and movable clamping portions 75 are provided on the movable clamping plate 73. The movable clamping portions 75 are located between the two fixed clamping portions 74. At least one fixed placement groove 741 and at least one fixed abutment portion 742 are provided at intervals on the fixed clamping portions 74, and at least one movable placement groove 751 and at least one movable abutment portion 752 are provided at intervals on the movable clamping portions 75. Both the fixed placement groove 741 and the movable placement groove 751 are used to insert the pipe. The fixed placement groove 741 is used in conjunction with the movable abutment portion 752, and the fixed abutment portion 742 is used in conjunction with the movable placement groove 751. The first push rod device 71 is connected to the movable clamping plate 73 and is used to drive the movable clamping plate 73 to move, so that the fixed abutment part 742 on the movable clamping plate 73 and the other side wall of the fixed placement groove 741 jointly clamp the pipe, realizing the clamping and handling of one pipe; if the movable placement groove 751 is also filled with a pipe, the movable placement groove 751 and the fixed abutment part 742 will also jointly clamp another pipe, realizing the synchronous clamping and handling of at least two pipes.

[0039] To accommodate the discharge of pipes of different lengths, such as Figure 3 As shown, the workbench 12 has a third slide rail 127 on the left and right sides of the discharge station. The discharge hopper 11 includes a left discharge hopper 111 and a right discharge hopper 112. One end of the left discharge hopper 111 and one end of the right discharge hopper 112 are nested on the third slide rail 127. Users can manually push the left discharge hopper 111 and the right discharge hopper 112 closer to each other or further apart to accommodate the discharge of pipes of different lengths. This avoids the discharge hopper 11 being too long or too short, which would affect the discharge effect of the pipes and ensure that each pipe is stably discharged into the discharge hopper 11, thus realizing the discharge and collection of pipes.

[0040] The upper part of the left discharge hopper 111 and the upper part of the right discharge hopper 112 are both provided with a feeding device 113 for orderly feeding of pipes. The feeding device 113 is close to the feeding end of the discharge hopper 11. The feeding device 113 includes a second push rod device 114 and a baffle plate 115 connected to the drive end of the second push rod device 114. The baffle plate 115 can be controlled to move up and down at the feeding end of the discharge hopper 11 by the second push rod device 114. When the baffle plate 115 descends, the bottom of the baffle plate 115 abuts against the bottom wall of the feeding end or there is a gap between them. The gap is much smaller than the diameter of the pipe, thereby limiting the pipe falling to the feeding end of the discharge hopper 11. When the baffle plate 115 rises, the pipe can slide down along the internal path of the discharge hopper 11 to the bottom of the discharge hopper 11, realizing the pipe collection work. Secondly, when the user needs to remove the pipes from the hopper 11, the feeding device 113 can drive the baffle plate 115 to descend, so that the pipes to be discharged later can be piled up at the feeding end. At this time, it is convenient for the user to remove the pipes that have been collected and placed in the hopper 11. After the pipes are removed, the baffle plate 115 can be driven to rise, so that the piled pipes can enter the discharge hopper 11, and finally the normal discharge and collection work can continue.

[0041] Preferably, in other embodiments, one end of the left discharge hopper 111 and one end of the right discharge hopper 112 are both nested on the third slide rail 127 and are fixedly connected to the corresponding processing component 41, so that the left discharge hopper 111 and the right discharge hopper 112 move synchronously with the corresponding processing component 41, realizing the automated synchronous width adjustment function to meet the processing and discharge work of pipes of different lengths, with a wide range of applications and high practicality.

[0042] Furthermore, in order to achieve automatic pipe feeding and delivery, such as Figure 1 , Figure 2 and Figure 7 As shown, the feeding mechanism 2 includes a feeding hopper 21, a feeding platform 22, and a conveying motor device 23. The feeding hopper 21 is equipped with multiple first synchronous belt conveyors 211. Multiple locking components 212 are spaced apart on the first synchronous belt conveyors 211, and locking slots 213 for accommodating pipes are provided between two adjacent locking components 212. When the multiple first synchronous belt conveyors 211 rotate, the pipes stored in the feeding hopper 21 can be locked into the locking slots 213 and moved upward along the conveying direction to the feeding platform 22. Since the locking slots 213 are spaced apart, the pipes can be automatically fed into the feeding platform 22 at intervals, realizing the automatic feeding of pipes.

[0043] The feeding platform 22 is equipped with a top material device 221 and multiple second synchronous belt conveyors 222. A synchronous shaft 223 is provided between the first synchronous belt conveyor 211 and the second synchronous belt conveyor 222. The synchronous shaft 223 is connected to the conveyor motor device 23, thereby realizing the pipe conveying operation.

[0044] The top material device 221 is located at the discharge end of the feeding platform 22. The top material device 221 includes at least one top material cylinder 2211 and a top material plate 2212 connected to the top material cylinder 2211 one by one. The top material plate 2212 is provided with upwardly extending limiting members 2213 on both the left and right sides. The limiting members 2213 are located in the gap between two adjacent second synchronous belt conveyors 222. The limiting members 2213 are provided with a feeding groove 2214 for accommodating pipes. The limiting member 2213 is provided with a limiting plate 2215 at one end near the workbench 12.

[0045] In this embodiment, the top-feeding device 221 includes two top-feeding cylinders 2211 and two top-feeding plates 2212. When the first pipe is conveyed to the discharge end and abuts against the limiting plate 2215 on the first top-feeding plate 2212, the pipe is limited. The first top-feeding cylinder 2211 can drive the first top-feeding plate 2212 to move upward, so that the pipe is placed in the feeding groove 2214 on the first top-feeding plate 2212 and is pushed away from the feeding surface of the feeding platform 22. At this time, the first pipe is located at the handling station. Similarly, the next pipe will fall into the feeding groove 2214 of the second top-feeding plate 2212 and be pushed away from the feeding surface by the second top-feeding cylinder 2211. At this time, the second pipe is also located at the handling station. Subsequently, the two pipes are subjected to automated processes such as alignment correction, handling, rounding, punching and discharge.

[0046] The feed hopper 21 has two adjusting plates 214 on its inner sides. The two adjusting plates 214 are nested on the adjusting rod of the feed hopper 21 and can be relatively close or far apart. By adjusting the distance between the two adjusting plates 214, the length of the pipe placed at the feed hopper 21 can be limited, so as to adapt to the feeding and conveying of pipes of different lengths, which has high applicability.

[0047] In summary, this invention automatically feeds the material into the feeding machine via a feeding mechanism. A conveying mechanism automatically and orderly delivers the pipes to be processed or cut to a specified length to the rounding mechanism, processing mechanism, and discharge hopper. The rounding and processing mechanisms align and correct each pipe to ensure accurate rounding and punching of both ends. The entire pipe production process requires no human intervention, achieving automated and orderly feeding and processing of pipes. This improves pipe handling efficiency, processing accuracy, and production safety, ultimately enhancing both production efficiency and quality.

[0048] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
