Description

Technical Field

[0001] This utility model relates to the field of round tube manufacturing technology, specifically to an automated round tube manufacturing equipment. Background Technology

[0002] Some round tubes require the use of round tube forming machines during manufacturing to achieve specific shapes, dimensional accuracy, and economical mass production, especially in the fields of building decoration, industrial piping, and precision components. However, existing round tube forming machines have the following shortcomings in actual use: First, after forming, the formed round tubes need to be manually removed, which not only poses a risk of injuring workers' hands but also reduces tube manufacturing efficiency; second, the formed round tubes generally require workers to manually arrange them one by one onto the unloading buffer rack for subsequent robotic arm handling, which is inconvenient. Therefore, an automated round tube manufacturing device was designed. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned shortcomings by providing an automated round tube manufacturing device. This device can automatically remove the formed round tubes, avoiding the risk of injuring workers' hands and improving tube manufacturing efficiency. It can also arrange the formed round tubes neatly for subsequent gripping by robotic arms, making them more convenient to use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automated round tube manufacturing device includes a manufacturing rack and a unloading rack arranged adjacent to each other;

[0006] The fabrication frame is provided with a fabrication groove, and a lower rolling mold is fixed at the bottom of the fabrication groove. One end of the fabrication groove is slidably connected to a fabrication slide block, which is used to drive the fabrication slide block to rise or fall. A rolling mandrel is installed on the fabrication slide block at one end. An upper rolling mold is set above the lower rolling mold, which is used to drive the upper rolling mold to rise or fall. A tube removal mechanism is also installed on the fabrication frame. The slide block hydraulic cylinder is installed on the fabrication frame, the upper mold hydraulic cylinder is installed on the fabrication slide block, and the rolling mandrel is set between the upper rolling mold and the lower rolling mold. When the slide block hydraulic cylinder drives the fabrication slide block to move down and the upper mold hydraulic cylinder drives the upper rolling mold to move down, the lower rolling mold, the rolling mandrel, and the upper rolling mold together form a circular tube mold cavity.

[0007] A buffer plate is obliquely installed on the unloading rack. An L-shaped fixing plate is fixed on the buffer plate. An adjusting plate is set opposite the horizontal part of the L-shaped fixing plate. One end of the adjusting plate is rotatably connected to a V-shaped unloading groove on one side of the buffer plate. This is used to drive the unloading drive mechanism to flip the V-shaped unloading groove up and down. The V-shaped unloading groove is set on the side directly opposite the vertical part of the L-shaped fixing plate. The L-shaped fixing plate, the adjusting plate, and the V-shaped unloading groove together form a buffer position. When the unloading drive mechanism drives the V-shaped unloading groove to flip up, the round tube in the V-shaped unloading groove rolls into the buffer position under the action of gravity. The lowest end of the buffer plate is set towards the vertical part of the L-shaped fixing plate. The tube release mechanism is used to push the round tube formed on the rolled mandrel into the V-shaped unloading groove.

[0008] Furthermore, the lower rolling die is provided with a lower semi-circular cavity, and the bottom of the upper rolling die is provided with an upper semi-circular cavity. After the upper rolling die moves down, the upper semi-circular cavity and the lower semi-circular cavity surround each other to form a complete circular cavity.

[0009] Furthermore, the tube removal mechanism includes a tube removal slide rail parallel to the rolled mandrel, a tube removal carriage sliding along the tube removal slide rail, and a tube removal electric cylinder for driving the tube removal carriage to slide along the tube removal slide rail. Both the tube removal electric cylinder and the tube removal slide rail are fixed to the unloading frame. Tube removal connecting blocks are symmetrically arranged on the tube removal carriage. The tube removal slide rail is parallel to the V-shaped unloading groove and is located at the rear end of the V-shaped unloading groove. The tube removal electric cylinder is used to drive the tube removal carriage to slide back and forth. The tube removal connecting blocks... A tube-detaching electric push rod is fixed horizontally at the top. The piston rod of the tube-detaching electric push rod is driven and connected to an arc-shaped locking block. The openings of the arc-shaped locking blocks on the two tube-detaching connecting blocks are set facing each other. When the rolling mandrel is in the rising state, the arc-shaped locking blocks are set close to the rear end of the rolling mandrel. The tube-detaching electric push rod is used to drive the two arc-shaped locking blocks to move closer or further away from each other. When the two arc-shaped locking blocks are in the close state, the arc-shaped locking blocks are close to the rolling mandrel and are located at the rear end of the formed round tube.

[0010] Furthermore, a feeding connecting block is fixed on the outer left side of the V-shaped feeding groove, and feeding fixing seats are symmetrically fixed on one side of the feeding connecting block. A feeding fixing shaft is fixedly connected to the two feeding fixing seats. Two buffer seats are symmetrically fixed on the feeding frame below the side of the buffer plate. The V-shaped feeding groove is rotatably connected to the buffer seats through the feeding fixing shaft. The feeding drive mechanism includes a feeding electric cylinder that is inclined and rotatably mounted on the feeding frame. The upper end is fixed to the feeding connecting rod in the middle of the outer left side of the V-shaped feeding groove. A drive connecting head is driven to the piston rod head of the feeding electric cylinder. The side of the feeding connecting rod abuts against the feeding connecting block. The lower end of the feeding connecting rod is rotatably connected to the drive connecting head through the feeding rotating shaft.

[0011] Furthermore, a left arc-shaped protrusion and a right arc-shaped protrusion are respectively provided on the inner side of the V-shaped feeding groove. When the V-shaped feeding groove is in a horizontal state, the horizontal height of the right arc-shaped protrusion is higher than that of the left arc-shaped protrusion.

[0012] Furthermore, the unloading rack is provided with an adjustment drive mechanism, which is used to drive the adjustment plate closer to or further away from the lateral part of the L-shaped fixed plate;

[0013] The buffer plate has multiple feeding grooves arranged in parallel, and the feeding grooves are arranged parallel to the vertical part of the L-shaped fixed plate. The adjustment drive mechanism includes a feeding slider slidably connected in the feeding groove, a feeding connecting plate connecting the multiple feeding sliders, a feeding slide rod and a feeding screw arranged parallel to the feeding groove. The feeding slide rod is fixed on the feeding frame below the buffer plate, and the feeding screw is rotatably connected to the feeding frame below the buffer plate. The feeding connecting plate has a feeding internal thread hole opposite the feeding screw. One end of the feeding screw passes through the feeding frame and is connected to a handwheel. The top end of the feeding slider extends out of the feeding groove and is fixedly connected to an adjustment plate.

[0014] The beneficial effects of this utility model are:

[0015] 1. When in use, place the thin plate into the production groove, and the hydraulic cylinder of the slide block drives the production slide block to move down, so that the rolling mandrel presses the middle of the thin plate into the rolling lower die. At this time, the middle of the thin plate is curved into an arc shape and the two ends are raised. The upper die hydraulic cylinder drives the rolling upper die to move down, and the rolling upper die presses against the two ends of the thin plate until the rolling lower die, the rolling mandrel and the rolling upper die are closed to form a round tube cavity, and the thin plate is made into a round tube.

[0016] 2. After the round tube is formed, the upper mold hydraulic cylinder drives the rolling upper mold to move upward, and the slide hydraulic cylinder drives the making slide to move upward. The round tube formed on the rolling mandrel is pushed into the V-shaped feeding groove through the tube release mechanism.

[0017] 3. When the round tube falls into the V-shaped feeding trough, the feeding drive mechanism drives the V-shaped feeding trough to flip upward, and the round tube rolls from the V-shaped feeding trough onto the buffer plate under the action of gravity. Since the lowest end of the buffer plate is set towards the vertical part of the L-shaped fixing plate, under the action of gravity and inertia, the leftmost round tube rolls and abuts against the vertical part of the L-shaped fixing plate, and the round tubes on the right end abut against each other, and are neatly arranged. This utility model can automatically remove the formed round tubes, avoiding the risk of crushing the workers' hands and improving the tube making efficiency. It can also make the formed round tubes neatly arranged so that they can be grasped by the robot arm later, making them more convenient to use. Attached Figure Description

[0030] The formed round tube is 40mm. Detailed Implementation

[0031] like Figure 1-10As shown, an automated round tube manufacturing device includes a manufacturing frame 21 and a unloading frame 31 arranged adjacent to each other. The manufacturing frame 21 has a manufacturing groove 211, and a lower rolling die 22 is fixed to the bottom of the groove 211. One end of the manufacturing groove 211 is slidably connected to a manufacturing slide block 23, a slide block hydraulic cylinder for driving the slide block 23 to rise or fall, a rolling mandrel 25 mounted on the slide block 23, an upper rolling die 26 positioned above the lower rolling die 22, an upper die hydraulic cylinder 27 for driving the upper rolling die 26 to rise or fall, and a tube removal mechanism 24 mounted on the manufacturing frame 21. The slide block hydraulic cylinder is mounted on the manufacturing frame 21, the upper die hydraulic cylinder 27 is mounted on the manufacturing slide block 23, and the rolling mandrel 25 is positioned between the upper rolling die 26 and the lower rolling die 22. The slide block hydraulic cylinder drives the manufacturing slide block 23 to move downwards, and the upper die hydraulic cylinder 27 drives the upper rolling die 26 to move downwards. At the same time, the lower rolling die 22, the rolling mandrel 25, and the upper rolling die 26 together form a circular tube mold cavity; a buffer plate 32 is obliquely installed on the unloading rack 31, an L-shaped fixing plate 33 is fixed on the buffer plate 32, and an adjusting plate 34 is provided on the horizontal part of the L-shaped fixing plate 33. One end of the adjusting plate 34 is rotatably connected to a V-shaped unloading groove 35 on one side of the buffer plate 32, which is used to drive the V-shaped unloading groove 35 to flip up and down. Located on the side directly opposite the vertical part of the L-shaped fixing plate 33, the L-shaped fixing plate 33, the adjusting plate 34, and the V-shaped feeding groove 35 together form a buffer position. When the feeding drive mechanism drives the V-shaped feeding groove 35 to flip upward, the round tube in the V-shaped feeding groove 35 rolls into the buffer position under the action of gravity. The lowest end of the buffer plate 32 is set towards the vertical part of the L-shaped fixing plate 33. The tube release mechanism 24 is used to push the round tube formed on the rolled mandrel 25 into the V-shaped feeding groove 35.

[0032] In use, the thin plate is placed into the forming groove 211. The sliding hydraulic cylinder drives the forming slide 23 to move downward, so that the rolling mandrel 25 presses the middle of the thin plate against the rolling lower die 22. At this time, the middle of the thin plate is curved into an arc shape and the two ends are raised. The upper die hydraulic cylinder 27 drives the rolling upper die 26 to move downward, and the rolling upper die 26 presses against the two ends of the thin plate until the rolling lower die 22, the rolling mandrel 25 and the rolling upper die 26 surround and form a cylindrical mold cavity, making the thin plate into a cylindrical tube. After the cylindrical tube is formed, the upper die hydraulic cylinder 27 drives the rolling upper die 26 to move upward, and the sliding hydraulic cylinder drives the forming slide 23 to move upward. The cylindrical tube formed on the rolling mandrel 25 is pushed into the V-shaped unloading mechanism 24. When the round tube falls into the V-shaped feeding groove 35, the feeding drive mechanism drives the V-shaped feeding groove 35 to flip upward. Under the action of gravity, the round tube rolls from the V-shaped feeding groove 35 onto the buffer plate 32. Since the lowest end of the buffer plate 32 is set towards the vertical part of the L-shaped fixing plate 33, under the action of gravity and inertia, the leftmost round tube rolls and abuts against the vertical part of the L-shaped fixing plate 33, and the round tubes on the right end abut against each other and are neatly arranged. This utility model can automatically remove the formed round tubes, avoiding the risk of injuring the workers' hands and improving the tube making efficiency. It can also make the formed round tubes neatly arranged so that they can be grasped by the robot arm later, making it more convenient to use.

[0033] like Figure 1-10 As shown, the lower rolling die 22 is provided with a lower semi-circular cavity, and the bottom of the upper rolling die 26 is provided with an upper semi-circular cavity. After the upper rolling die 26 moves down, the upper semi-circular cavity and the lower semi-circular cavity surround each other to form a complete circular cavity. In this embodiment, the upper semi-circular cavity and the lower semi-circular cavity surround each other to form a complete circular cavity. The rolling mandrel 25 is coaxially arranged with the complete circular cavity, and the thin plate of the rolling mandrel 25 and the complete circular cavity are pressed into a circular tube.

[0034] like Figure 1-10As shown, the tube removal mechanism 24 includes a tube removal slide rail 241 parallel to the mandrel 25, a tube removal carriage 242 sliding along the tube removal slide rail 241, and a tube removal electric cylinder 243 for driving the tube removal carriage 242 to slide along the tube removal slide rail 241. Both the tube removal electric cylinder 243 and the tube removal slide rail 241 are fixed on the unloading frame 31. Tube removal connecting blocks 244 are symmetrically arranged on the tube removal carriage 242. Parallel to the V-shaped unloading groove 35 and located at the rear end of the V-shaped unloading groove 35, the tube-removing electric cylinder 243 is used to drive the tube-removing slide 242 to slide back and forth. A tube-removing electric push rod 245 is horizontally fixed on the tube-removing connecting block 244. An arc-shaped locking block 246 is driven and connected to the piston rod head of the tube-removing electric push rod 245. The openings of the arc-shaped locking blocks 246 on the two tube-removing connecting blocks 244 are arranged facing each other. When the rolling mandrel 25 is in the rising state, the arc-shaped locking block 246 is located close to the rear end of the rolling mandrel 25. The tube-removing electric push rod 245 is used to drive the two arc-shaped locking blocks 246 to move closer or further away from each other. When the two arc-shaped locking blocks 246 are in the close state, the arc-shaped locking block 246 is close to the rolling mandrel 25, and the arc-shaped locking block 246 is located at the rear end of the formed round tube 40. In this embodiment, after the round tube is formed, the upper mold hydraulic cylinder 27 drives the rolling upper mold 26 to move upward. The slide block hydraulic cylinder drives the slide block 23 to move upward. The two arc-shaped clamping blocks 246 are driven to move closer to each other by the tube removal electric push rod 245. The arc-shaped clamping blocks 246 are brought close to the two sides of the rolled mandrel 25 at the rear end of the formed round tube 40. The tube removal electric cylinder 243 drives the tube removal slide 242 to move forward along the tube removal slide rail 241. The arc-shaped clamping blocks 246 push against the rear end of the formed round tube 40 and push it forward into the V-shaped unloading groove 35.

[0035] like Figure 1-10As shown, a feeding connecting block 351 is fixed on the outer left side of the V-shaped feeding trough 35, and feeding fixing seats 352 are symmetrically fixed on one side of the feeding connecting block 351. A feeding fixing shaft 353 is fixedly connected to the two feeding fixing seats 352. Two buffer seats 311 are symmetrically fixed on the feeding frame 31 below the side of the buffer plate 32. The V-shaped feeding trough 35 is rotatably connected to the buffer seats 311 through the feeding fixing shaft 353. The feeding drive mechanism includes a feeding electric cylinder 361 that is inclined and rotatably mounted on the feeding frame 31, and a feeding connecting rod 362 whose upper end is fixed to the middle of the outer left side of the V-shaped feeding trough 35. The piston rod of the feeding electric cylinder 361 is driven to connect to a drive connector 363. The side of the feeding connecting rod 362 abuts against the feeding connecting block 351. The lower end of the feeding connecting rod 362 is rotatably connected to the drive connector 363 through the feeding rotating shaft 364. In this embodiment, when the round tube falls into the V-shaped feeding groove 35, the piston rod of the feeding electric cylinder 361 extends out and is rotatably connected to the drive connector 363 through the lower end of the feeding connecting rod 362. The V-shaped feeding groove 35 flips upward with the feeding fixing shaft 353 as the center, so that the round tube in the V-shaped feeding groove 35 rolls down along the left side of the V-shaped feeding groove 35 and rolls to the buffer position.

[0036] like Figure 1-10 As shown, a left arc-shaped protrusion 354 and a right arc-shaped protrusion 355 are respectively provided on the inner side of the V-shaped feeding groove 35. When the V-shaped feeding groove 35 is in a horizontal state, the horizontal height of the right arc-shaped protrusion 355 is higher than that of the left arc-shaped protrusion 354. In this embodiment, the left arc-shaped protrusion 354 and the right arc-shaped protrusion 355 can prevent the round tube from getting stuck in the V-shaped feeding groove 35. The left arc-shaped protrusion 354 can also make the round tube roll out when the V-shaped feeding groove 35 rotates to a higher state, increasing the inertial force of the round tube rolling into the buffer position. When the horizontal height of the right arc-shaped protrusion 355 is higher than that of the left arc-shaped protrusion 354, it can prevent the round tube in the flipped state from rolling out from the right side of the V-shaped feeding groove 35.

[0037] like Figure 1-10As shown, the unloading rack 31 is equipped with an adjustment drive mechanism, which drives the adjustment plate 34 to move closer to or further away from the horizontal portion of the L-shaped fixed plate 33; multiple unloading grooves 321 are arranged parallel to each other on the buffer plate 32, and the unloading grooves 321 are arranged parallel to the vertical portion of the L-shaped fixed plate 33; the adjustment drive mechanism includes unloading sliders 371 slidably connected in the unloading grooves 321, an unloading connecting plate 372 connecting the multiple unloading sliders 371, an unloading rod 373 and an unloading screw 374 arranged parallel to the unloading grooves 321, the unloading rod 373 being fixed to the unloading rack 31 below the buffer plate 32, and the unloading screw 374 being rotatably connected to the buffer plate 32. On the lower feeding rack 31, the feeding connecting plate 372 is provided with a feeding internal thread hole opposite the feeding screw 374. One end of the feeding screw 374 passes through the feeding rack 31 and is connected to a handwheel 375. The top end of the feeding slider 371 extends out of the feeding groove 321 and is fixedly connected to an adjusting plate 34. In this embodiment, when the handwheel 375 is manually turned, the handwheel 375 drives the feeding connecting plate 372 to slide along the feeding slide bar 373 through the feeding screw 374. At the same time, the feeding slider 371 slides along the feeding groove 321, so that the adjusting plate 34 moves closer to or further away from the horizontal part of the L-shaped fixing plate 33, adjusting the distance between the adjusting plate 34 and the horizontal part of the L-shaped fixing plate 33, making it suitable for use as a buffer for round tubes of various lengths.

[0038] It also includes a PLC controller connected to a power cord. A distance sensor is installed on the adjustment plate 34. The slide hydraulic cylinder, the upper mold hydraulic cylinder 27, the tube removal mechanism 24, the distance sensor, and the material feeding drive mechanism are all electrically connected to the PLC controller. The detection end of the distance sensor is set directly inside the V-shaped material feeding groove 35. When the distance sensor detects a round tube inside the V-shaped material feeding groove 35, the controller controls the material feeding drive mechanism to start feeding.

[0039] The specific embodiments described herein are merely illustrative examples of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the scope defined by this utility model.
