Description

Technical Field

[0001] This invention belongs to the field of metal pipe processing and feeding technology, and particularly relates to an automated feeding device for metal pipe processing. Background Technology

[0002] Pipe fittings are a general term for components in a piping system that serve functions such as connection, control, direction change, flow diversion, sealing, and support. Pipe fittings processing and feeding devices are required during the processing of pipe fittings. Referring to the pipe fitting processing feeding device described in patent application CN116692452A, which relates to the field of pipe fitting processing, the device includes a base and a mounting plate, with a fixing frame fixedly connected to one side of the top of the mounting plate. In this invention, the design of the gripping cylinder, its interlocking with the mounting block, and the connection between the connecting shaft and the second motor allows for easy feeding of pipe fittings by simply rotating the gripping cylinder, while also preventing unloaded pipe fittings from being fed. This design also improves the ease of disassembling the gripping cylinder during maintenance. Furthermore, the design of the buffer plate cushions the impact of the pipe fitting falling from the gripping trough to the unloading plate, effectively reducing the collision impact between the pipe fitting and the unloading plate, and decreasing the probability of wear and dents on the outer wall of the pipe fitting. Current metal pipe processing feeding devices generally use a single conveying mechanism for feeding (such as the aforementioned techniques). These typically transport metal pipes of fixed sizes and specifications. When changing to transport pipes of different specifications, the compatibility is low because pipes are long and slender materials requiring continuous transport. Furthermore, as a section of pipe is being transported at different stages, the conveying speed and force should be adjusted according to the relative position between the pipe and the processing mechanism to avoid excessive conveying speed causing processing position deviation and excessive conveying force affecting processing results. To address these issues, an automated feeding device for metal pipe processing with improved performance is provided. Summary of the Invention

[0003] This invention provides an automated feeding device for metal pipe processing, aiming to solve the problems of current feeding devices for metal pipe processing that generally use a single conveying mechanism for feeding. These devices typically transport metal pipes of fixed specifications and sizes, and have low compatibility when transporting pipes of different specifications. This is because pipes are long and thin materials that need to be transported continuously. Furthermore, when a section of pipe is being transported at different stages, the conveying speed and conveying force should be adjusted according to the relative position between the pipe and the processing mechanism to avoid the problem of excessive conveying speed causing processing position deviation and excessive conveying force affecting the processing effect.

[0004] The present invention is implemented as follows: an automated feeding device for processing metal pipe fittings includes a main frame assembly: an upper main lifting hydraulic cylinder is provided on the top of the main frame assembly, a feeding end conveying mechanism is provided on the top of the upper main lifting hydraulic cylinder, an intermediate conveying mechanism is fixedly connected to the outer wall of the feeding end conveying mechanism, an upper mounting base is fixedly connected to the main frame assembly, and an output end conveying mechanism is fixedly connected to the top of the upper mounting base. The discharge end conveying mechanism includes an upper transmission bracket. A first transmission motor is fixedly connected to the outer wall of the upper transmission bracket. The output shaft of the first transmission motor is fixedly connected to a rotating rod via a coupling. The outer wall of the rotating rod is movably connected to the inner wall of the upper transmission bracket. A large transmission disc is fixedly connected to one end of the rotating rod. An inner transmission groove is formed on the outer wall of the large transmission disc. Several rubber blocks are fixedly connected to the inner wall of the inner transmission groove. Through the design of the discharge end conveying mechanism, the wide-mouthed inner transmission groove facilitates the placement of metal pipes transported by the intermediate conveying mechanism onto the inner transmission groove, thereby enabling them to be conveyed further. The conveying mechanism uses rubber blocks to improve the gripping force on the metal pipes, thereby enhancing the conveying effect and preventing conveying failures caused by both the metal pipes and the inner transmission groove having high smoothness. In operation, the connection between the upper mounting base and the lower connecting base is first installed and adjusted as needed, ensuring the external metal pipes are positioned precisely on the inner transmission groove. The first conveying motor is then started and controlled to rotate the large transmission disc, thus conveying the metal pipes to the processing station. At this point, the conveying speed is relatively slow, lower than that of the intermediate conveying mechanism.

[0005] Preferably, the outer wall of the lower connecting seat is provided with several fixing bolts, and the lower connecting seat and the upper mounting seat are fixedly connected by bolts; The outer walls of the upper mounting base and the lower connecting base are provided with several connecting holes at equal intervals along the longitudinal direction.

[0006] Preferably, the feeding end conveying mechanism includes an upper lifting mounting base mechanism, the top of which is provided with a second transmission motor. The output shaft of the second transmission motor is fixedly connected to a small transmission disc via a coupling, and the outer wall of the small transmission disc is fixedly connected with a rubber layer. Through the setting of the feeding end conveying mechanism, in use, according to the height of the external metal pipe to be conveyed, the first set of lifting hydraulic cylinders is started and controlled to adjust the working height of the small transmission disc and the intermediate conveying mechanism to achieve the best working effect. The feeding end conveying mechanism, as the first conveying mechanism used in this feeding device, works in conjunction with a small transmission disc and a second transmission motor. During use, the first telescopic hydraulic cylinder is activated and controlled to extend and retract the position of the upper sliding inner seat and the second transmission motor according to the outer diameter of the metal pipe. This ensures that the small transmission disc fits snugly against the outer wall of the metal pipe. Activating and controlling the second transmission motor then drives the small transmission disc to rotate, thereby conveying the material towards the intermediate conveying mechanism and the discharge end conveying mechanism. The conveying speed can be relatively fast at this time.

[0007] Preferably, the upper lifting mounting base mechanism includes a first auxiliary lifting hydraulic cylinder fixedly mounted on the main frame assembly. One end of the first auxiliary lifting hydraulic cylinder is fixedly connected to an upper lifting mounting base. The top of the upper lifting mounting base is fixedly connected to an upper fixed outer seat. An upper sliding inner seat is slidably connected to the inner wall of the upper fixed outer seat. A first telescopic hydraulic cylinder is fixedly connected between the upper fixed outer seat and the upper sliding inner seat. The second transmission motor is mounted on the outer wall of the upper sliding inner seat.

[0008] Preferably, the intermediate conveying mechanism includes two external connecting rods fixedly mounted on the outer wall of the upper lifting mounting base. One end of each external connecting rod is fixedly connected to a central base plate mechanism. A connecting sleeve is fixedly connected to the outer wall of the central base plate mechanism. A second auxiliary lifting hydraulic cylinder is fixedly connected to the top of the connecting sleeve. One end of the second auxiliary lifting hydraulic cylinder is fixedly connected to a pushing mechanism. Through the intermediate conveying mechanism, during use, after the metal pipe is completely conveyed to the discharge end conveying mechanism via the small transmission disc and the second conveying motor, the second auxiliary lifting hydraulic cylinder is activated and controlled to adjust the height of the pushing mechanism. This ensures that the cylindrical pushing groove in the pushing seat is flush with the height of the metal pipe before activating and controlling the second auxiliary lifting hydraulic cylinder. The lifting hydraulic cylinder enables the movement of a gear. When the gear meshes with the fixed gear plate, and is pushed forward by the second telescopic hydraulic cylinder, the gear rotates simultaneously. This rotation drives the movable rack along the direction of movement of the second telescopic hydraulic cylinder, thereby inserting the metal pipe into the cylindrical push slot and pushing it between two small transmission discs to the pipe processing station. The conveying speed of the second telescopic hydraulic cylinder is adjusted in real time based on the detection data from the pressure sensor probe. When the pressure data detected by the pressure sensor probe increases, the processing speed of the metal pipe is slower, and the conveying speed of the second telescopic hydraulic cylinder should be appropriately reduced to achieve appropriate applicability and ensure the standard processing shape of the metal pipe.

[0009] Preferably, the pushing mechanism includes a pushing seat, the inner wall of which is provided with a cylindrical pushing groove, and a pressure sensor probe is embedded in the inner wall of the cylindrical pushing groove. The pressure sensor probe is a MEMS micro pressure probe.

[0010] Preferably, the central seat plate mechanism includes a central seat plate and a second telescopic hydraulic cylinder fixedly mounted on an outer connecting rod. One end of the second telescopic hydraulic cylinder is fixedly connected to a retaining seat. The inner wall of the retaining seat is movably connected to a gear via a rotating shaft. The outer wall of the central seat plate is fixedly connected to a fixed toothed plate. The outer wall of the fixed toothed plate meshes with the outer wall of the gear. The outer wall of the central seat plate is movably connected to a movable toothed rod via a mounting block. The outer wall of the gear meshes with the outer wall of the movable toothed rod.

[0011] Preferably, the main frame assembly includes an upper frame body, the inner wall of which is provided with two lower main lifting hydraulic cylinders, and the bottom of the upper frame body is provided with a base mechanism. Through the configuration of the main frame assembly, the orientation of the loading device can be moved and adjusted to achieve better coordination with the original position of the metal pipe to be loaded and the processing station of the metal pipe. When the main lifting hydraulic cylinder is activated and controlled to lift the platform, the top of the disc slider contacts the inner wall of the limit slide groove, and the movable platform rotates along the pivot at the connection between the movable platform and the side frame, thereby adjusting the operating angle of the movable platform and the three conveying mechanisms on the movable platform. By controlling the directional motor, the three conveying mechanisms on the side frame and the upper movable platform are rotated, thereby adjusting the orientation of the three conveying mechanisms.

[0012] Preferably, the base mechanism includes a base, the bottom of the base is provided with several moving mechanisms, and the top of the base is fixedly connected with a directional motor; The moving mechanism includes a small lifting hydraulic cylinder fixedly installed at the bottom of the base. A base plate is fixedly connected to the bottom of the small lifting hydraulic cylinder, and several pulleys are provided at the bottom of the base plate. Through the base mechanism, in use, the position of the base plate and pulleys can be raised and lowered by starting and controlling the small lifting hydraulic cylinder. When the pulleys contact the ground, the position of the feeding device can be easily moved. By controlling the small lifting hydraulic cylinder to raise and lower the position of the base plate and pulleys, the device's position stabilizes after the base contacts the ground.

[0013] Preferably, the base includes a side frame, the top inner wall of the side frame is movably connected to a movable platform via a pivot, the bottom of the movable platform has a limiting groove, the top of the lower main lifting hydraulic cylinder is fixedly connected to a disc slider, the top of the disc slider is slidably connected to the inner wall of the limiting groove, the bottom of the side frame is fixedly connected to several auxiliary movable frames, and the bottom of the auxiliary movable frames is slidably connected to the top of the base, the output shaft of the directional motor is fixedly connected to a large rotating rod via a coupling, and one end of the large rotating rod is fixedly connected to the bottom of the side frame.

[0014] Compared with the prior art, the embodiments of this application have the following main advantages: By setting up the feeding end conveying mechanism, during use, the first set of lifting hydraulic cylinders is started and controlled to adjust the height of the small transmission plate and the intermediate conveying mechanism according to the height of the external metal pipe to be conveyed, so as to achieve the best use effect. The feeding end conveying mechanism, as the first conveying mechanism used in this feeding device, works in conjunction with a small transmission disc and a second transmission motor. During use, the first telescopic hydraulic cylinder is activated and controlled to extend and retract the position of the upper sliding inner seat and the second transmission motor according to the outer diameter of the metal pipe. This ensures that the small transmission disc fits snugly against the outer wall of the metal pipe. The second transmission motor is then activated and controlled to drive the small transmission disc to rotate, thereby conveying the material towards the intermediate conveying mechanism and the discharge end conveying mechanism. The conveying speed can be relatively fast at this time. With the intermediate conveying mechanism, during use, after the metal pipe is completely conveyed to the discharge end conveying mechanism via the small transmission disc and the second transmission motor, the second auxiliary lifting hydraulic cylinder is activated and controlled to adjust the height of the pushing mechanism. This ensures that the cylindrical pushing groove in the pushing seat is flush with the height of the metal pipe. Activating and controlling the second auxiliary lifting hydraulic cylinder then moves the gear. When the gear meshes with the fixed tooth plate, and is pushed forward by the second telescopic hydraulic cylinder, the gear rotates simultaneously. This rotation drives the moving toothed rod along the direction of movement of the second telescopic hydraulic cylinder, thus inserting the metal pipe into the cylindrical pushing groove and pushing it between the two small transmission discs to the pipe processing station. The conveying speed of the second telescopic hydraulic cylinder is adjusted in real time based on the detection data from the pressure sensor probe. When the pressure data detected by the pressure sensor probe increases, the processing speed of the metal pipe is slower, and the conveying speed of the second telescopic hydraulic cylinder should be appropriately reduced to achieve appropriate applicability and ensure the standard processing shape of the metal pipe. By designing the discharge end conveying mechanism, the wide-mouthed inner transmission groove facilitates the placement of metal pipes transported by the intermediate conveying mechanism onto the inner transmission groove, enabling them to be conveyed to the processing station. The rubber block enhances the gripping force on the metal pipes, thereby improving the conveying effect and preventing conveying failures caused by both the metal pipes and the inner transmission groove having high smoothness. In the use of this mechanism, firstly, the connection position between the upper mounting base and the lower connecting base is installed and adjusted as needed, so that the external metal pipes are placed precisely on the inner transmission groove. By starting and controlling the first conveying motor to drive the large transmission disc to rotate, the metal pipes are conveyed to the processing station. At this time, the conveying speed is relatively slow, lower than the conveying speed of the intermediate conveying mechanism. By configuring the main frame assembly, the orientation of the feeding device can be moved and adjusted to achieve better coordination with the original position of the metal pipe to be fed and the processing station of the metal pipe. When the main lifting hydraulic cylinder is activated and controlled to lift the platform, the top of the disc slider contacts the inner wall of the limit slide groove, and the movable platform rotates along the pivot at the connection between the movable platform and the side frame, thereby adjusting the operating angle of the movable platform and the three conveying mechanisms on the movable platform. By controlling the directional motor, the three conveying mechanisms on the side frame and the upper movable platform are rotated, thereby adjusting the orientation of the three conveying mechanisms. With the base mechanism in place, the position of the base plate and pulleys is raised and lowered by starting and controlling the small lifting hydraulic cylinder. Once the pulleys are in contact with the ground, the loading device can be easily moved to a different position. The position of the base plate and pulleys is then stabilized after the base is in contact with the ground. Attached Figure Description

A rubber layer is fixedly connected to the outer wall of the small transmission disk 303. The upper lifting mounting base mechanism 301 includes a first auxiliary lifting hydraulic cylinder 3011 fixedly mounted on the main frame assembly 6. One end of the first auxiliary lifting hydraulic cylinder 3011 is fixedly connected to an upper lifting mounting base 3012. The top of the upper lifting mounting base 3012 is fixedly connected to an upper fixed outer seat 3013.

[0020] It should be noted that existing feeding devices for metal pipe processing generally use a single conveying mechanism for feeding, such as the aforementioned techniques. These devices typically transport metal pipes of fixed sizes. When changing to transport pipes of different sizes, the compatibility is low because pipes are long and thin materials that require continuous transport. Furthermore, when a section of pipe is being transported at different stages, the conveying speed and conveying force should be adjusted according to the relative position between the pipe and the processing mechanism to avoid excessive conveying speed causing deviation in the processing position and excessive conveying force affecting the processing effect.

[0021] Specifically, in this embodiment, the solution mainly uses the main frame assembly 6, the upper main lifting hydraulic cylinder 1, the feeding end conveying mechanism 3, the intermediate conveying mechanism 5, the upper mounting base 4, and the discharging end conveying mechanism 2. In use, firstly, the orientation of the feeding end conveying mechanism 3, the intermediate conveying mechanism 5, and the discharging end conveying mechanism 2 is adjusted; when the lower main lifting hydraulic cylinder 602 is started and controlled to lift, after the top of the disc slider contacts the inner wall of the limit slide groove 6012, the movable platform 6011 rotates along the pivot at the connection between the movable platform 6011 and the side frame 6013, thereby adjusting the orientation of the movable platform 6011 and the three conveying mechanisms on the movable platform 6011. By controlling the directional motor 6032, the three conveying mechanisms on the side frame 6013 and the upper movable platform 6011 are rotated, thereby adjusting the orientation of the three conveying mechanisms. Then, put into use: During use, according to the height of the external metal pipe to be conveyed, start and control the use of the first set of lifting hydraulic cylinders 3011 to adjust the height of the small transmission plate 303 and the intermediate transmission mechanism 5 to achieve the best use effect. The feeding end conveying mechanism 3 is the first conveying mechanism used in this feeding device. It works in conjunction with the small transmission disc 303 and the second transmission motor 302. In use, according to the outer diameter of the metal pipe, the first telescopic hydraulic cylinder 3015 is started and controlled to extend and adjust the position of the upper sliding inner seat 3014 and the second transmission motor 302, so that the small transmission disc 303 fits snugly against the outer wall of the metal pipe. The second transmission motor 302 is started and controlled to drive the small transmission disc 303 to rotate, thereby realizing the conveying towards the middle conveying mechanism 5 and the discharge end conveying mechanism 2. At this time, the conveying speed can be relatively fast. After the metal pipe is completely conveyed to the discharge end conveying mechanism 2 via the small transmission disc 303 and the second transmission motor 302, the second auxiliary lifting hydraulic cylinder 503 is activated and controlled to adjust the working height of the pushing mechanism 504. This ensures that the cylindrical pushing groove in the pushing seat 5041 is flush with the height of the metal pipe. Activating and controlling the second auxiliary lifting hydraulic cylinder 503 then moves the gear 5013. When the gear 5013 meshes with the fixed toothed plate 5012, and is pushed forward by the second telescopic hydraulic cylinder 5014, the gear 5013 moves forward while simultaneously rotating. 3. Rotation drives the movable rack 5015 along the direction of movement of the second telescopic hydraulic cylinder 5014, thereby inserting the metal pipe into the cylindrical push groove and pushing it between the two small transmission discs 303 to the pipe processing station. The conveying speed of the second telescopic hydraulic cylinder 5014 is adjusted in real time according to the detection data of the pressure sensor probe 5042. When the detected pressure data of the pressure sensor probe 5042 increases, the processing speed of the metal pipe is slower. The conveying speed of the second telescopic hydraulic cylinder 5014 should be appropriately reduced to achieve the corresponding applicability and ensure the standard processing shape of the metal pipe. Install and adjust the connection position between the upper mounting base 4 and the lower connecting base 206 as needed, so that the external metal pipe is placed on the inner transmission groove 203. By starting and controlling the first transmission motor 201 to drive the large transmission disk 202 to rotate, the metal pipe is transported to the processing station. At this time, the transmission speed is relatively slow and lower than the transmission speed of the intermediate transmission mechanism 5.

[0022] In this embodiment, the wide-mouthed inner transmission groove 203, provided by the discharge end conveying mechanism 2, facilitates the placement of metal pipes conveyed by the intermediate conveying mechanism 5 onto the inner transmission groove 203, thereby conveying them to the processing station. The rubber block 204 enhances the gripping force on the metal pipes, thereby improving the conveying effect and preventing conveying failure caused by both the metal pipes and the inner transmission groove 203 having high smoothness. In the use of this mechanism, firstly, the connection position between the upper mounting base 4 and the lower connecting base 206 is installed and adjusted as needed, so that the external metal pipes are placed precisely on the inner transmission groove 203. By starting and controlling the first conveying motor 201 to drive the large transmission disc 202 to rotate, the metal pipes are conveyed to the processing station. At this time, the conveying speed is relatively slow, lower than the conveying speed of the intermediate conveying mechanism 5. In this embodiment, by setting up the feeding end conveying mechanism 3, during use, according to the height of the external metal pipe to be conveyed, the first auxiliary lifting hydraulic cylinder 3011 is started and controlled to adjust the working height of the small transmission plate 303 and the intermediate conveying mechanism 5 to achieve the best working effect. The feeding end conveying mechanism 3 is the first conveying mechanism used in this feeding device. It works in conjunction with the small transmission disc 303 and the second transmission motor 302. In use, according to the outer diameter of the metal pipe, the first telescopic hydraulic cylinder 3015 is started and controlled to extend and adjust the position of the upper sliding inner seat 3014 and the second transmission motor 302, so that the small transmission disc 303 fits snugly against the outer wall of the metal pipe. The second transmission motor 302 is started and controlled to drive the small transmission disc 303 to rotate, thereby realizing the conveying towards the middle conveying mechanism 5 and the discharge end conveying mechanism 2. At this time, the conveying speed can be relatively fast. In this embodiment, through the intermediate conveying mechanism 5, during use, after the metal pipe is completely conveyed to the discharge end conveying mechanism 2 via the small transmission disc 303 and the second conveying motor 302, the second auxiliary lifting hydraulic cylinder 503 is activated and controlled to adjust the working height of the pushing mechanism 504, so that the cylindrical pushing groove in the pushing seat 5041 is flush with the height of the metal pipe. Activating and controlling the second auxiliary lifting hydraulic cylinder 503 then moves the gear 5013. When the gear 5013 meshes with the fixed toothed plate 5012, and is pushed forward by the second telescopic hydraulic cylinder 5014, the gear 5013 moves forward simultaneously. The rotating mechanism, via gear 5013, drives the movable rack 5015 along the direction of movement of the second telescopic hydraulic cylinder 5014. This allows the metal pipe to be inserted into the cylindrical push slot and pushed between the two small transmission discs 303 to the pipe processing station. The conveying speed of the second telescopic hydraulic cylinder 5014 is adjusted in real time based on the detection data from the pressure sensor probe 5042. When the pressure data detected by the pressure sensor probe 5042 increases, the processing speed of the metal pipe is slower, and the conveying speed of the second telescopic hydraulic cylinder 5014 should be appropriately reduced to achieve appropriate applicability and ensure the standard processing shape of the metal pipe.

The base mechanism 603 includes a base 6031, several moving mechanisms 6033 are provided at the bottom of the base 6031, and a directional motor 6032 is fixedly connected to the top of the base 6031. The moving mechanism 6033 includes a small lifting hydraulic cylinder fixedly installed at the bottom of the base 6031. A base plate is fixedly connected to the bottom of the small lifting hydraulic cylinder, and several pulleys are provided at the bottom of the base plate. The base 6031 includes a side frame 6013. The top inner wall of the side frame 6013 is movably connected to a movable platform 6011 via a pivot. The bottom of the movable platform 6011 has a limiting groove 6012. The top of the lower main lifting hydraulic cylinder 602 is fixedly connected to a disc slider. The top of the disc slider is slidably connected to the inner wall of the limiting groove 6012. Several auxiliary movable frames 6014 are fixedly connected to the bottom of the side frame 6013. The bottom of the auxiliary movable frames 6014 is slidably connected to the top of the base 6031. The output shaft of the directional motor 6032 is fixedly connected to a large rotating rod via a coupling. One end of the large rotating rod is fixedly connected to the bottom of the side frame 6013.

[0024] In this embodiment, the main frame assembly 6 allows for the movement and adjustment of the feeding device's orientation, achieving better coordination with the original position of the metal pipe to be fed and the processing station of the metal pipe. When the main lifting hydraulic cylinder 602 is activated and controlled to lift the disc slider, after the top of the disc slider contacts the inner wall of the limit slide groove 6012, the movable platform 6011 rotates along the pivot at the connection between the movable platform 6011 and the side frame 6013, thereby adjusting the operating angle of the movable platform 6011 and the three conveying mechanisms on the movable platform 6011. By controlling the directional motor 6032, the three conveying mechanisms on the side frame 6013 and the upper movable platform 6011 are rotated, thereby adjusting the orientation of the three conveying mechanisms. In this embodiment, by setting the base mechanism 603, the position of the base plate and pulley is raised and lowered by starting and controlling the small lifting hydraulic cylinder during use. When the pulley contacts the ground, the position of the feeding device can be easily moved. By controlling the small lifting hydraulic cylinder to raise and lower the position of the base plate and pulley, the position of the device stabilizes after the base 6031 contacts the ground.
