Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a pipe laser cutting and punching production line. Background Technology

[0002] In traditional pipe processing, cutting and punching are two separate processes. Cutting is typically performed on separate cutting equipment, and after cutting, the pipe needs to be manually or mechanically transferred to the punching equipment for the next step. However, when the punching equipment is handling other tasks, the pipe must wait for it to become available before punching; conversely, when the punching equipment is ready, the cutting process may still be incomplete, leaving the punching equipment idle. The excessive time spent on pipe transfer and waiting between processes prevents continuous, efficient, and automated production. Furthermore, punching equipment typically only punches in one direction of the pipe, limiting its applicability. Therefore, it is necessary to improve existing technology to address these issues.

[0031] The present invention will be described in detail below with reference to specific embodiments.

[0032] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0033] This utility model provides a tube laser cutting and punching production line, such as Figures 1 to 11 As shown, it includes a feeding conveyor 1, a pipe cutting device 2, a discharging and pushing device 3, and a punching and unloading device 4. The feeding conveyor 1 is used to feed pipes; the pipe cutting device 2 is used to pick up the pipes from the feeding conveyor 1 and cut them; the discharging and pushing device 3 is used to discharge the cut pipes and push them to the punching and unloading device 4; the punching and unloading device 4 is used to punch holes in the cut pipes and unload the punched pipes; there are two punching and unloading devices 4, and the punching operation directions of the two punching and unloading devices 4 are opposite. The opposite punching operation direction means that the punching sequence is also opposite to the previously preset sequence, that is, if the punching sequence of one punching and unloading device 4 is from one end to the other end, then the punching sequence of the other punching and unloading device 4 is from the other end in the reverse order.

[0034] Based on the above structural configuration, this type of tube laser cutting and punching production line can continuously feed tubes into each processing step, realizing fully automated tube processing. It not only reduces the waiting and transfer time between the cutting and punching steps, shortens the production cycle, and improves production efficiency, but also allows for the selection and activation of the appropriate punching and blanking device 4 according to the characteristics of the product, thus adapting to the processing needs of different tubes and achieving wider applicability.

[0035] In this embodiment, the punching and unloading device 4 includes a punching frame 41 and a punching conveyor belt 42, a first punching mechanism 43, a second punching mechanism 44, and a unloading mechanism 45 disposed on the punching frame 41.

The first punching mechanism 43 is used to punch a first through hole in the pipe on the punching conveyor belt 42. The second punching mechanism 44 is used to punch a second through hole in the pipe on the punching conveyor belt 42. The unloading mechanism 45 is disposed at the end of the punching conveyor belt 42 and is used to unload the punched pipe. By using the first punching mechanism 43 and the second punching mechanism 44, punching can be performed on different positions of the pipe, thereby improving production efficiency.

[0036] In this embodiment, the punching frame 41 is provided with a fixed mounting base 411 and a sliding mounting base 412. The fixed mounting base 411 is disposed on one side of the punching conveyor belt 42, and the sliding mounting base 412 is slidably connected to the other side of the punching conveyor belt 42. The first punching mechanism 43 includes a first lifting assembly 431, a first tube feeding assembly 432, a first mandrel assembly 433, a first positioning assembly 434, and a first punching assembly 435. The first lifting assembly 431 is disposed on the punching conveyor belt 42 and is capable of lifting the punching components on the punching conveyor belt 42. The pipe, after the first punching, is placed on the punching conveyor belt 42. The first pipe feeding assembly 432 is slidably connected to the sliding mounting base 412 and can deliver the pipe, after being lifted by the first lifting assembly 431, to the first mandrel assembly 433. The first mandrel assembly 433, the first positioning assembly 434, and the first punching assembly 435 are all mounted on the fixed mounting base 411. The first positioning assembly 434 can position the pipe in the first mandrel assembly 433, and the first punching assembly 435 can punch the first through hole in the positioned pipe. Specifically, there are two sets of the first punching assembly 435, which are respectively located on both sides of the first mandrel assembly 433. When the pipe needs to be punched with the first through hole, the pipe on the punching conveyor belt 42 is lifted by the first lifting component 431, the first pipe feeding component 432 picks up the pipe and sends it to the first mandrel component 433, then the first positioning component 434 fixes the pipe, and the first punching component 435 punches the first through hole. After the first punching is completed, the first pipe feeding component 432 takes out the pipe, the first lifting component 431 places it on the punching conveyor belt 42, and the punching conveyor belt 42 sends it to the next process.

[0037] In this embodiment, the second punching mechanism 44 includes a second lifting component 441, a second pushing component 442, a second mandrel component 443, a second positioning component 444, and a second punching component 445. The second lifting component 441 is disposed on the punching frame 41 and can lift the pipe after the first punching on the punching conveyor belt 42 and place the pipe after the second punching on the punching conveyor belt 42. The second pushing component 442 is disposed on the fixed mounting base 411 and can push the pipe lifted by the second lifting component 441 to the second mandrel component 443. The second mandrel component 443 is disposed on the sliding mounting base 412. The second positioning component 444 is disposed on the second mandrel component 443 and can position the pipe on the second mandrel component 443. The second punching component 445 is disposed on the sliding mounting base 412 and can punch a second through hole in the positioned pipe. When the pipe needs to be punched with a second through hole, the pipe on the punching conveyor belt 42 is lifted by the second lifting component 441, and the second pushing component 442 pushes the pipe to the second mandrel component 443. Then the second positioning component 444 fixes the pipe, and the second punching component 445 punches the second through hole. After the second punching is completed, the second lifting component 441 places it on the punching conveyor belt 42, and the unloading mechanism 45 unloads it.

[0038] The purpose of setting up the fixed mounting base 411 and the sliding mounting base 412 is to adjust the distance between the fixed mounting base 411 and the sliding mounting base 412 to accommodate pipes of different lengths.

[0039] In this embodiment, the punching and unloading device 4 further includes a weld inspection mechanism 46. The first end of the punching conveyor belt 42 is equipped with a connecting pipe mechanism 47 and a transfer mechanism 48. The connecting pipe mechanism 47 receives and fixes the pipe pushed by the discharge pusher 3. The transfer mechanism 48 lifts the pipe on the connecting pipe mechanism 47 and places it on the punching conveyor belt 42. The weld inspection mechanism 46 is mounted on the sliding mounting base 412 and is used to inspect the welds of the pipe on the connecting pipe mechanism 47. When the discharge pusher 3 pushes the cut pipe to the connecting pipe mechanism 47, the connecting pipe mechanism 47 fixes the pipe, and the weld inspection mechanism 46 inspects it. After the inspection is completed, the transfer mechanism 48 lifts the pipe and transfers it to the punching conveyor belt 42, thus completing the weld inspection operation.

[0040] In this embodiment, the feeding conveyor 1 includes a feeding conveyor frame 10 and a conveyor belt 11 and a feeding conveyor belt 12 disposed on the feeding conveyor frame 10. The conveyor belt 11 is used to transport pipes to the feeding conveyor belt 12. The feeding conveyor belt 12 is provided with a plurality of pipe limiting seats 121, and adjacent pipe limiting seats 121 form a pipe placement position. The feeding conveyor belt 12 is used to receive the pipes on the conveyor belt 11 and can divide the pipes one by one into the pipe placement positions. The pipe limiting seats 121 can ensure that the pipes move stably and quickly on the feeding conveyor belt 12, preventing the pipes from being displaced or rolled during the conveying process and making it difficult to be lifted by the lifting and supporting mechanism 21 described below, thereby improving the feeding efficiency.

[0041] In this embodiment, the pipe feeding and cutting device 2 includes a lifting and supporting mechanism 21, a pipe feeding mechanism 22, a laser cutting mechanism 23, and a flipping mechanism 24. The lifting and supporting mechanism 21 is used to lift the pipe on the feeding conveyor belt 12 and support the pipe.

The laser cutting mechanism 23 is used to cut the pipe. The flipping mechanism 24 is used to support the cut pipe and drop the cut pipe to the discharge and pushing device 3.

[0042] In this embodiment, the tube feeding mechanism 22 includes a first tube feeding mechanism 221 and a second tube feeding mechanism 222; the first tube feeding mechanism 221 includes a first tube feeding frame 2211 and a first tube clamping assembly 2212, and the second tube feeding mechanism 222 includes a second tube feeding frame 2221, a second tube clamping assembly 2222 and a third tube clamping assembly 2223; the first tube clamping assembly 2212 is slidably connected to the first tube feeding frame 2211 and can feed the tube to the second tube clamping assembly 2222; the second tube clamping assembly 2222 is slidably connected to the second tube feeding frame 2221 and can feed the tube to the third tube clamping assembly 2223; the third tube clamping assembly 2223 is fixedly mounted on the second tube feeding frame 2221; the laser cutting mechanism 23 is slidably connected to the second tube feeding frame 2221; and the lifting and supporting mechanism 21 is mounted on the first tube feeding frame 2211. The first clamping assembly 2212, the second clamping assembly 2222, and the third clamping assembly 2223 respectively support the tail, middle, and head of the pipe, and the pipe can be rotated by these clamping assemblies so that the pipe can be cut stably.

[0043] In this embodiment, the flipping mechanism 24 includes a flipping frame 241, a mounting plate 242, a flipping cylinder 243, and a flipping plate 244; the mounting plate 242 is slidably connected to the flipping frame 241, the fixed end of the flipping cylinder 243 is hinged to the mounting plate 242, the telescopic end is hinged to the flipping plate 244, and the flipping plate 244 is hinged to the mounting plate 242.

[0044] By cooperating with the lifting and holding mechanism 21, the first pipe feeding mechanism 221 and the second pipe feeding mechanism 222, the pipe can be smoothly fed to the laser cutting mechanism 23 for cutting. After cutting, the pipe falls to the discharge conveyor belt 31 described below under the action of the flipping mechanism 24, thus completing the pipe cutting and unloading operation.

[0045] In this embodiment, the discharge and pushing device 3 includes a discharge frame 30 and a discharge conveyor belt 31 and a pushing mechanism 32 disposed on the discharge frame 30; the pushing mechanism 32 is provided with two sets, each capable of pushing the pipe on the discharge conveyor belt 31 to one of the punching and unloading devices 4.

[0047] Where there is no conflict, the above embodiments and features can be combined with each other.
