[0033] One of the purposes of the present invention is to provide an automatic processing line for pipe fittings, which adopts machines instead of manual labor to transfer pipe fittings, and can realize the fully automated operation of the pipe fittings processing line, so as to solve the problems of manual participation in the transfer of pipe fittings in the existing pipe fittings processing lines, which not only has a long process cycle and a large number of work-in-progress in the processing line, but also has high labor intensity, low work efficiency, high safety hazards for personnel, high labor costs, and poor consistency of pipe fitting quality.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Embodiment 1

[0036] like Figure 1As shown, this embodiment provides an automatic pipe processing line 100, including a feeding mechanism 1, a pipe cutting mechanism, a pipe section transfer mechanism, a pipe section adjustment mechanism, a pipe section flattening mechanism 6, a grooving mechanism 7, a tapping mechanism 8, a pipe fitting shifting mechanism and a control system.

[0037] In this embodiment, the loading mechanism 1 includes a loading rack, a lifting unit and a discharging unit. The loading rack is provided with a silo for storing the pipes to be processed. The lifting unit is arranged on one side of the loading rack, and is used to lift the pipes to be processed in the silo from low to high to the discharging unit. The discharging unit is connected to the pipe cutting mechanism, and is used to discharge the pipes to be processed to the pipe cutting mechanism. Among them, the lifting unit can adopt a waterwheel-type rotary feeding mechanism, which mainly includes an inclined annular conveyor belt (or conveyor chain), a rotary drive mechanism, and a plurality of hooks for placing pipe fittings distributed along the circumference of the conveyor belt on the outer surface of the conveyor belt. The lower end of the annular conveyor belt is connected to the discharge port of the silo, and the high end of the annular conveyor belt is connected to the discharge unit. The rotary drive mechanism drives the annular conveyor belt (or conveyor chain) to rotate. When the hook rotates to the discharge port of the silo with the annular conveyor belt, it receives a pipe fitting to be processed. After the pipe fitting to be processed is transported to the loading position of the discharge unit with the hook and the annular conveyor belt, it is separated from the hook, thereby completing a pipe fitting lifting and feeding. The rotary feeding mechanism is a prior art and will not be described in detail here. The above-mentioned discharge unit adopts the existing automatic pipe discharging mechanism, which can uniformly arrange the pipe fittings lifted by the lifting unit according to the equidistant positioning device, so as to facilitate the discharge of the pipe fittings one by one to the pipe cutting mechanism.

[0038] In this embodiment, the tube cutting mechanism is preferably a laser tube cutting machine, which is an existing tube cutting mechanism, mainly comprising a laser tube cutting machine rear chuck 2 and a laser cutting machine main unit 3. The laser cutting machine main unit 3 also comprises a laser tube cutting machine front chuck and a laser cutting head. After the laser tube cutting machine receives the discharge signal from the discharge unit, the two-axis laser tube cutting machine rear chuck 2 grabs the tube to be processed and transports it to the laser cutting machine main unit 3. After the laser tube cutting machine front chuck of the laser cutting machine main unit 3 receives the tube to be processed sent by the rear chuck, it assists in clamping the tube to be processed, and the laser cutting head cuts the product according to the program requirements to form the required tube section.

[0039] In this embodiment, the pipe section transfer mechanism includes an automatic transmission line 4 and a product sensing device arranged on the automatic transmission line 4. The automatic transmission line 4 is connected with the discharge end of the pipe cutting mechanism and is located below the discharge end of the pipe cutting mechanism. The product sensing device can sense whether there is a pipe section on the automatic transmission line 4. When the product sensing device senses that there is a pipe section on the automatic transmission line 4, the automatic transmission line 4 can automatically start to transport the pipe section to the pipe section adjustment mechanism. The above-mentioned product sensing device is preferably a conveyor line touch switch, which is communicatively connected with the aforementioned control system. The automatic transmission line 4 preferably adopts a belt conveyor line.

[0040] In this embodiment, the pipe section adjustment mechanism is preferably an arc mouth recognition unit 5, which recognizes the arc mouth direction of the pipe section by infrared rays and automatically adjusts it. During adjustment, the pipe section is adjusted mainly by turning the flap driven by the cylinder.

[0041] In this embodiment, a punching mechanism 9 is also included. The pipe section adjustment mechanism, the pipe section flattening mechanism 6, the grooving mechanism 7, the tapping mechanism 8 and the punching mechanism 9 are arranged in sequence. The punching mechanism 9 is used to punch the pipe section after tapping. The pipe shifting mechanism can shift the pipe section to the punching mechanism 9; the punching mechanism 9 is communicatively connected with the control system.

[0042] In this embodiment, it also includes a press-bending and forming mechanism 10, and the pipe section adjustment mechanism, the pipe section flattening mechanism 6, the grooving mechanism 7, the tapping mechanism 8, the punching mechanism 9 and the press-bending and forming mechanism 10 are arranged in sequence. The press-bending and forming mechanism 10 is used to press-bend and form the pipe section after the punching process; the pipe fitting shifting mechanism can shift the pipe section to the press-bending and forming mechanism 10; the press-bending and forming mechanism 10 is communicatively connected with the control system.

[0043] In this embodiment, a finished pipe collection device is also included, which is preferably arranged at the end of the automatic pipe processing line 100 to collect the processed pipe sections.

[0044] In this embodiment, the pipe displacement mechanism is a rack manipulator. Specifically, in this embodiment, two sets of rack manipulators are provided, namely a first rack manipulator 14 and a second rack manipulator 13.

[0045] In this embodiment, a palletizing robot 12 is also included, which is used to grab the processed pipe sections and stack them on the finished pipe collection device.

[0046] The above-mentioned automatic pipe processing line 100 can process round pipes as well as square pipes. The working process and working principle of the automatic pipe processing line 100 are specifically described below by taking the processing of a square pipe with a specification of 40*20*1.5mm as an example. The length of the processed pipe section is 250mm to 350mm.

[0047] The automatic pipe processing line 100 proposed in this embodiment mainly processes pipes according to the process of loading → feeding → laser cutting → arc mouth identification and adjustment → robot grabbing and shifting → plug flattening → slotting → tapping → punching → bending → stacking. The overall process flow of the automatic pipe processing line 100 for processing pipes is described below:

[0048] 1. Put the whole bundle of pipes to be processed into the loading rack silo of the loading mechanism 1, and lift part of the pipes to be processed in the silo to the discharge unit through the lifting unit, and the discharge unit discharges the pipes to be processed one by one to the pipe cutting mechanism.

[0049] 2. After the pipe cutting mechanism receives the discharge signal from the discharge unit, the two-axis laser pipe cutting machine rear chuck 2 grabs the pipe to be processed and transports it to the laser cutting machine host 3. After the laser pipe cutting machine front chuck of the laser cutting machine host 3 receives the pipe to be processed sent by the rear chuck, it assists in clamping the pipe to be processed. The laser cutting head cuts the product according to the program requirements to form the required pipe segment. The length of the formed pipe segment is generally 250mm to 350mm. 。

[0050] 3. The cut pipe segment automatically falls onto the automatic conveyor line 4. After the conveyor line touches the pipe segment, the automatic conveyor line 4 automatically starts and transfers the pipe segment to the arc mouth recognition unit 5.

[0051] Fourth, the arc mouth identification unit 5 identifies the arc mouth direction of the pipe section through infrared rays and automatically adjusts it. Here, a cylinder can be set to push the pipe section to the corresponding station, waiting for the first transfer manipulator 14 to pick up the material.

[0052] 5. The first transfer manipulator 14 grabs the pipe section with the arc direction adjusted on the arc identification unit 5 and transfers it to the pipe section flattening mechanism 6 for plugging and flattening. The pipe section flattening mechanism 6 includes a reinforcing sheet material trough 61 and a plugging sheet cylinder 62. The plugging sheet cylinder 62 pushes the reinforcing sheet in the reinforcing sheet material trough 61 into the square tube, and the oil cylinder presses down to flatten and form. The reinforcing sheet is put into the material trough manually, and about 200 sheets can be put in at a time.

[0053] 6. The first transfer robot 14 moves the flattened pipe section to the notching mechanism 7 for notching.

[0054] 7. The first transfer manipulator 14 moves the grooved pipe section to the tapping mechanism 8 of the tapping station for tapping. The tapping mechanism 8 is generally equipped with an automatic oil dripping device to lubricate the tap.

[0055] 8. Start the second row manipulator 13, and move the tapped pipe section to the punching mechanism 9 for punching. The punching mechanism 9 generally uses an arc punching machine, such as an internal punching arc punching machine (the punching knife is inside the pipe, and the upper and lower punching are separated without depression). The servo advance and retreat oil cylinder 901 controls the arc punching machine to advance and retreat, and is NC-adjusted; arc punching action description: After the servo advance and retreat oil cylinder 901 advances to support the pipe material, the oil cylinder of the arc punching machine moves to punch the arc opening on one side, and then the servo advance and retreat oil cylinder 901 retreats a certain distance, and the oil cylinder of the arc punching machine moves to punch the arc opening on the other side, and the arc punching angle changes through the arc opening drop difference on the upper and lower sides. In actual operation, punching or not punching can be selected according to product requirements.

[0056] 9. The second row manipulator 13 moves the punched pipe segment to the bending forming mechanism 10 for bending. In actual operation, bending or not bending can be selected according to product requirements. If bending is required, the bending propulsion cylinder 102 pushes the pipe segment to the right bending position, and the bending oil cylinder 101 presses down to bend the pipe segment into shape. The second row manipulator 13 moves the bent pipe segment to the storage positioning frame 111 of the robot picking station 11; if bending is not required, the second row manipulator 13 moves the tapped or punched pipe segment to the non-bending discharge position 16.

[0057] 10. The stacking robot grabs the pipe section at the material picking station 11 or the unbending material discharging station 16 and stacks it into a finished pipe collection device; the finished pipe collection device generally uses a material frame 15.

[0058] In this embodiment, Figure 1 As shown, the automatic pipe processing line 100 is divided into an X-axis processing line and a Y-axis processing line as a whole, and the X-axis processing line and the Y-axis processing line intersect and are perpendicular. The pipe cutting mechanism, the automatic transmission line 4 and the arc mouth recognition unit 5 are arranged in sequence on the X-axis processing line, and the feeding mechanism 1 is located on one side of the pipe cutting mechanism and is arranged in connection with the pipe cutting mechanism. The arc mouth recognition unit 5, the pipe section flattening mechanism 6, the grooving mechanism 7, the tapping mechanism 8, the punching mechanism 9, the bending forming mechanism 10, the robot material picking station 11 and the stacking robot 12 are arranged in sequence on the Y-axis processing line, and the arc mouth recognition unit 5 is located at the corner intersection of the X-axis processing line and the Y-axis processing line. The non-bending material discharging position 16 is arranged side by side with the robot material picking station 11.

[0059] The first transfer robot 14 is arranged on one side of the Y-direction processing line, and includes three groups of air claws arranged along the Y-direction. A group of air claws is respectively arranged between the arc mouth recognition unit 5 and the pipe segment flattening mechanism 6, between the pipe segment flattening mechanism 6 and the notching mechanism 7, and between the notching mechanism 7 and the tapping mechanism 8. Each group of air claws is equipped with an X-direction driving cylinder and a Y-direction driving cylinder. The X-direction driving cylinder is arranged on the piston rod of the Y-direction driving cylinder, and the air claws are arranged on the piston rod of the X-direction driving cylinder. Taking a set of air claws between the arc-mouth recognition unit 5 and the pipe-segment flattening mechanism 6 as an example, its working principle is as follows: the Y-direction driving cylinder drives the air claw to move along the Y direction until it is aligned with the arc-mouth recognition unit 5 - the X-direction driving cylinder drives the air claw to move forward along the X direction to the arc-mouth recognition unit 5 to pick up the material - the air claw clamps the pipe segment - the X-direction driving cylinder drives the air claw to retreat along the X direction to the gap with the arc-mouth recognition unit 5 - the Y-direction driving cylinder drives the air claw to move along the Y direction to align with the pipe-segment flattening mechanism 6 - the X-direction driving cylinder drives the air claw to move forward along the X direction to the pipe-segment flattening mechanism 6 - the air claw releases the pipe segment - the X-direction driving cylinder drives the air claw to retreat along the X direction to the gap with the pipe-segment flattening mechanism 6 - the Y-direction driving cylinder drives the air claw to return along the Y direction to align with the arc-mouth recognition unit 5, waiting for the processing to be completed - the above-mentioned actions are repeated until all the pipe segments processed by the arc-mouth recognition unit 5 are moved to the pipe-segment flattening mechanism 6. The working methods of the remaining groups of air claws in the first transfer robot 14 are the same as those described above and will not be repeated here.

[0060] Correspondingly, the second row frame manipulator 13 is arranged at the top of the Y-axis processing line and crosses the tapping mechanism 8, the punching mechanism 9, the press-bending mechanism 10 and the robot material-retrieving station 11. The second row frame manipulator 13 includes three groups of air claws arranged along the Y-axis, one group of air claws is respectively arranged between the tapping mechanism 8 and the punching mechanism 9, between the punching mechanism 9 and the press-bending mechanism 10, and between the press-bending mechanism 10 and the robot material-retrieving station 11, each group of air claws is equipped with a Z-axis driving cylinder and a Y-axis driving cylinder, the Z-axis driving cylinder is arranged on the piston rod of the Y-axis driving cylinder, and the air claws are arranged on the piston rod of the Z-axis driving cylinder. Taking a group of air claws between the tapping mechanism 8 and the punching mechanism 9 as an example, its working principle is as follows: the Y-direction driving cylinder drives the air claw to move along the Y direction until it is aligned with the tapping mechanism 8 - the Z-direction driving cylinder drives the air claw to descend along the Z direction (vertical) to the tapping mechanism 8 to pick up the material - the air claw clamps the pipe section - the Z-direction driving cylinder drives the air claw to rise and retract along the Z direction to the interval with the tapping mechanism 8 - the Y-direction driving cylinder drives the air claw to move along the Y direction until it is aligned with the punching mechanism 9 - the Z-direction driving cylinder drives the air claw to descend along the Z direction to the punching mechanism 9 - the air claw releases the pipe section - the Z-direction driving cylinder drives the air claw to rise and retract along the Z direction to the interval with the punching mechanism 9 - the Y-direction driving cylinder drives the air claw to return along the Y direction to align with the tapping mechanism 8 and wait for the processing to be completed - the above-mentioned actions are repeated until all the pipe sections processed by the tapping mechanism 8 are moved to the punching mechanism 9. The working methods of the remaining groups of air claws in the second rack manipulator 13 are the same as those described above and will not be repeated here.

[0061] In actual operation, the duration of each process in the entire pipe automatic processing line 100 is as follows:

[0062] Punching and cutting takes about 4 seconds per piece. When a complete 6M piece is cut, it needs to be withdrawn to the tail end for loading, which takes about 7 seconds per piece on average.

[0063] Pipe section flattening mechanism 6, plugging 1.5s, flattening 4s; a total of 5.5s;

[0064] The slotting mechanism 7 and the punching mechanism 9 are both 4s;

[0065] Tapping mechanism 84s;

[0066] Each group of air grippers completes one pipe segment conveying: 3s;

[0067] Press-bending forming mechanism 10,5s.

[0068] From the above, it can be seen that the automatic processing line 100 for pipe fittings proposed by the present invention completes the production by cooperating between machine processing and manipulator transfer, realizing full automation of pipe fitting processing, laying the foundation for intelligent production, and enabling unattended operation at night. The above-mentioned automatic processing line 100 for pipe fittings changes the existing manual transfer of pipe fittings to machine (i.e., manipulator) transfer, and one person can simultaneously manage multiple automatic processing lines 100 for pipe fittings, which not only reduces the number of operators, solves the problem of high labor intensity of personnel, eliminates the safety hazards of manual participation in the transfer of pipe fittings, greatly reduces labor costs, and greatly shortens the process cycle, reducing work-in-progress in the processing line; at the same time, since the contact between humans and pipe fittings is reduced, the quality of pipe fittings after processing can be effectively guaranteed, and the consistency of pipe fitting quality can be improved.

[0069] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.

The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope.
