Description

Technical Field

[0001] This invention belongs to the field of short pipe machine technology, and particularly relates to a short pipe machine and its usage method. Background Technology

[0002] A pipe flaring machine is a specialized piece of equipment used to process short-length pipes, primarily for flaring short pipes. It has a wide range of applications, capable of flaring pipes of varying lengths, especially those that traditional flaring machines cannot handle. The equipment is easy and flexible to operate, with most accessories being interchangeable with those of ordinary flaring machines, reducing manufacturing difficulty and failure rates. The pipe flaring machine is also energy-efficient and environmentally friendly, lowering energy consumption and operating costs. These features make it outstanding in specific applications, particularly when processing short-length pipes.

[0003] The short pipe machine mainly works by fixing the pipe at the flaring station, pressing the pipe with a clamping cylinder, pushing the clamping plate with a pressing cylinder, pushing the mold into the pipe with a pushing cylinder, using a vacuum bag to draw air to make the pipe fit the mold, cooling the pipe with external water, shrinking the core-pulling cylinder, and ejecting the pipe with a discharge cylinder to complete the flaring.

[0004] However, in the existing technology, the clamping plate cannot be clamped according to the size of the pipe, and the clamping plate cannot provide sufficient clamping force. At the same time, the burrs and uneven parts on the top of the pipe cause uneven force on the clamping plate, which causes the pipe to loosen, shift and deform during processing, thus affecting the processing accuracy.

[0017] The present invention also provides a method of using the above-mentioned short pipe machine, comprising the following steps:

[0018] Step 1: Fix the pipe to the top of the mold, aligning the pipe with the mold. Then, use the push cylinder to move the fixing plate and the mold to the outside of the pipe. Start the clamping cylinder to push the clamping plate and the second fixing plate downwards, so that the top of the pipe is inside the installation port in the middle of the second fixing plate, thus clamping the pipe.

[0019] Step 2: When the top of the pipe is located on the inner wall of the installation port, start the first electric push rod to move the clamping block to the outside of the pipe and fit against the outside of the pipe to fix the pipe again. At the same time, start the electric telescopic block to move the grinding block to the top of the pipe. Start the motor to drive the rotating rod to rotate, so that the moving block drives the electric telescopic plate and the grinding block to move back and forth to grind the top of the pipe and remove burrs and uneven parts. When the grinding block moves, start the suction pump to collect the grinding waste into the collection box through the collection pipe.

[0020] Step 3: After the clamping plate and the second fixing plate fix the pipe in the mold, the vacuum bag on the machine body is used to draw air to make the pipe fit the mold and flare the pipe. After the flare is completed, the core-pulling cylinder is started to drive the unloading shaft to retract. The mold is pulled out from the processed pipe through the fixing welding plate, so that the pipe is separated from the mold.

[0021] Step 4: When the second fixing plate is damaged due to prolonged pressing, the second electric push rod is activated to retract, no longer restricting the slider. Then, the limiting plate is moved to separate the limiting rod from the limiting groove, no longer restricting the second fixing plate. The second fixing plate is then removed from the pressing plate by moving the slider. A new second fixing plate is then installed on the pressing plate for use.

[0022] The beneficial effects of this invention are as follows:

[0023] (1) The present invention uses the action of the second fixing plate and the clamping block to make the pipe fully pressed, preventing insufficient or uneven pressing force of the pressing plate. At the same time, the grinding block grinds the top of the pipe to remove burrs and uneven parts of the top of the pipe, and the collection box collects the waste, preventing the pressing plate and the second fixing plate from failing to press the pipe, so that the pipe will not loosen, shift or deform during the processing, which will affect the processing accuracy.

[0024] (2) The present invention replaces the second fixed plate and the adjustment mechanism by moving the limiting plate and the limiting rod, and by the action of the second electric push rod and the slider, thereby improving the replacement efficiency and preventing the second fixed plate and the adjustment device from being damaged after long-term use, which would affect the effect of pipe pressing and make it inconvenient to flare the pipe.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0035] This invention provides a short pipe machine, such as Figures 1 to 3 As shown, it includes a machine body 1, a processing table 2 is provided on the machine body 1, and a hydraulic flaring device is provided on the processing table 2;

[0036] The hydraulic flaring device includes a mold 3, a fixed welding plate 4, a flaring and unloading mechanism, a first fixed plate 5, a clamping plate 6, a telescopic rod 7, a clamping cylinder 8, a second fixed plate 9, and an adjustment mechanism. The bottom of the mold 3 is fixedly installed on the fixed welding plate 4, and the mold 3 and the fixed welding plate 4 are located on the top of the processing table 2. The flaring and unloading mechanism is located at the bottom of the fixed welding plate 4 and the processing table 2. The first fixed plate 5 is fixedly installed on the top of the machine body 1. The telescopic rod 7 and the clamping cylinder 8 are fixedly connected to the first fixed plate 5. The clamping plate 6 is fixedly installed at the bottom of the telescopic rod 7 and the clamping cylinder 8. The second fixed plate 9 is set at the bottom of the clamping plate 6. The second fixed plate 9 has an installation groove in the middle, and an adjustment mechanism is set inside the installation groove. There are two telescopic rods 7. The clamping cylinder 8 is located between the two telescopic rods 7. The clamping plate 6 is located at the bottom of the first fixed plate 5. The second fixed plate 9 is located at the top of the mold 3. The installation groove is located on both sides inside the second fixed plate 9. The second fixed plate 9 has an installation opening in the middle, and the installation groove communicates with the installation opening.

[0037] The fixed welding plate 4 facilitates the installation of the mold 3, aligning the pipe with the mold 3 to allow the flaring and unloading mechanism to flare the pipe and unload it. The first fixed plate 5 facilitates the fixing of the telescopic rod 7 and the clamping cylinder 8 to the machine body 1. The telescopic rod 7 improves the stability when the clamping cylinder 8 moves the clamping plate 6 and the second fixed plate 9. The mounting groove and mounting port facilitate the installation of the adjustment mechanism. When the pipe is fixed between the mold 3 and the second fixed plate 9, the flaring and unloading mechanism pushes the fixed welding plate 4 and the mold 3 upward, so that the bottom end of the pipe is inside the mold 3. At the same time, the clamping cylinder 8 drives the telescopic rod 7 to extend, pushing the clamping plate 6 and the second fixed plate 9 downward. The top of the pipe is positioned within the mounting opening of the second fixing plate 9. The adjusting mechanism clamps and limits the tops of pipes of different sizes and removes burrs from the tops of the pipes. When the clamping plate 6 and the second fixing plate 9 clamp and limit the pipe, it prevents the top of the pipe from being uneven, which would affect the clamping effect and prevent the pipe from becoming loose, shifting, or deformed during processing. It would also damage the clamping plate 6 and affect the processing accuracy.

[0038] like Figures 1 to 2 As shown, the flaring unloading mechanism includes a propulsion cylinder 10, a main push plate 11, an unloading plate 12, a core-pulling cylinder 13, an unloading shaft 14, a support rod 15, and a third fixing plate 16.

[0039] A main push plate 11 is provided on the top of the fixed welding plate 4, a push cylinder 10 is fixedly installed on the bottom of the fixed welding plate 4, a third fixed plate 16 is fixedly installed on the bottom of the push cylinder 10, the push cylinder 10 is provided in the middle of the third fixed plate 16, and a discharge plate 12 is fixedly installed on the bottom of the push cylinder 10. The top of the push cylinder 10 passes through the fixed welding plate 4 and is fixedly connected to the main push plate 11. A discharge shaft 14 is fixedly installed on the discharge plate 12. One end of the discharge shaft 14 passes through the third fixed plate 16 and is fixedly installed to the main push plate 11. A processing port is opened in the middle of the processing table 2. The fixed welding plate 4 is movably connected to the processing port. The main push plate 11 is located outside the mold 3. The third fixed plate 16 and the fixed welding plate 4 are connected by a support rod 15. The support rod 15 is movably connected to the fixed welding plate 4. The discharge shaft 14 is a telescopic rod. Both the discharge shaft 14 and the discharge plate 12 are fixedly installed to the machine body 1.

[0040] By fixing the fixed welding plate 4 and the mold 3 at the processing port of the processing table 2, the push cylinder 10 is fixed to the bottom of the fixed welding plate 4 by the third fixed plate 16, and the third fixed plate 16 and the fixed welding plate 4 are connected by the support rod 15. When the push cylinder 10 pushes the fixed welding plate 4 and the mold 3 to move along the support rod 15, the stability of the fixed welding plate 4 and the mold 3 when moving is improved. When the mold 3 moves to the outside of the pipe, the pipe is processed. When the processing is completed and unloading is required, the core pulling cylinder 13 and the unloading shaft 14 are installed by the unloading plate 12. The core pulling cylinder 13 is started to drive the unloading shaft 14 to retract. The fixed welding plate 4 drives the mold 3 to move downward, and the main push plate 11 separates the mold 3 from the pipe. The pipe is then removed from the machine body 1, and a new pipe is fixed for processing.

[0041] like Figures 3 to 7 As shown, the adjustment mechanism includes a mounting plate, a first electric push rod 17, a clamping block 18, a connecting rod 19, a fixing block 20, and a grinding structure;

[0042] One side of the mounting plate is fixedly installed to the inner wall of the mounting groove, and the other side of the mounting plate is fixedly installed with a clamping block 18. Two connecting rods 19 are fixedly installed on the top of the clamping block 18. The top of the two connecting rods 19 is movably connected to a fixing block 20. The fixing block 20 is fixedly installed to the inner wall of the mounting opening. The top of the fixing block 20 has a fixing groove, and a grinding structure is provided inside the fixing groove. The clamping block 18 is located inside the mounting opening, the connecting rods 19 are located on both sides of the fixing groove, the grinding structure is located on the top of the clamping block 18, and the clamping block 18 is arc-shaped. The mounting plate, the first electric push rod 17, the clamping block 18, and the connecting rods 19 are all symmetrically arranged with respect to the center of the mounting opening.

[0043] After the pipe is fixed between the second fixing plate 9 and the mold 3, the pushing cylinder 10 moves the fixing welding plate 4 and the mold 3 to the outside of the pipe. The clamping cylinder 8 is activated to extend the telescopic rod 7, pushing the clamping plate 6 and the second fixing plate 9 downward, so that the top of the pipe is located inside the installation port in the middle of the second fixing plate 9, thus clamping the pipe. Then, the first electric push rod 17 is activated to move the clamping block 18 to the outside of the pipe, so that the arc side of the clamping block 18 fits against the outside of the pipe, further restricting the pipe and improving its stability. Then, the grinding mechanism is activated to grind the top of the pipe, removing burrs and uneven parts, further improving the uniformity of the clamping between the second fixing plate 9 and the clamping plate 6, and improving the clamping effect of the clamping plate 6.

[0044] like Figures 6 to 8 As shown, the grinding structure includes a motor 21, a rotating rod 22, a moving block 23, an electric telescopic block 24, and a grinding block 25;

[0045] One side of the motor 21 is fixedly installed to the inner wall of the fixed groove, and the other side of the motor 21 is fixedly installed with a rotating rod 22. One side of the rotating rod 22 is rotatably connected to the inner wall of the fixed groove. One end of the rotating rod 22 is threadedly connected to a moving block 23. The top of the moving block 23 is slidably connected to the inner wall of the fixed groove. A grinding block 25 is fixedly installed on the top of the electric telescopic block 24. The grinding block 25 is located on the top of the clamping block 18. Collection boxes 26 are fixedly installed on both sides of the fixed end of the electric telescopic block 24. A suction pump 27 is fixedly installed on one side of the collection box 26. A collection pipe 28 is fixedly installed on one end of the suction pump 27. The collection pipes 28 are distributed in a linear array.

[0046] Once the pipe is fixed inside the installation port and the clamping block 18 further restricts the pipe, the electric telescopic block 24 is activated to drive the grinding block 25 downwards, so that the grinding block 25 moves to the top of the pipe and fits against it. The motor 21 is activated to drive the rotating rod 22 to rotate along the inner wall of the fixed groove, so that the moving block 23 moves along the rotating rod 22, and the electric telescopic block 24 drives the grinding block 25 to move back and forth on the top of the pipe to grind the top of the pipe and remove burrs and uneven areas. At the same time, the suction pump 27 is activated, so that when the electric telescopic block 24 drives the collection box 26 to move, the collection pipe 28 absorbs the waste after grinding. The collection efficiency is improved by the linear array distribution of the collection pipes 28, preventing waste from accumulating on the top of the pipe or falling between the pipe and the mold 3, which would not be conducive to the pressing and processing of the pipe.

[0047] like Figures 3 to 5 As shown, the bottom of the clamping plate 6 has two sliding grooves, and the top of the second fixing plate 9 is fixedly installed with a slider 29, which is slidably connected to the sliding groove. The inner wall of the top of the clamping plate 6 has a groove, and the inside of the groove is fixedly installed with a second electric push rod 30. One end of the second electric push rod 30 passes through the sliding groove and is inserted into the slider 29. The outer side of the second fixing plate 9 has two limiting grooves, and a limiting plate 31 is provided on one side of the limiting groove. The top of the limiting plate 31 is slidably connected to the bottom of the clamping plate 6, and a limiting rod 32 is fixedly installed on one side of the limiting plate 31, which is inserted into the limiting groove.

[0048] The second fixing plate 9 is easily installed at the bottom of the pressure plate 6 by connecting the slider 29 to the slide groove. The second electric push rod 30 is inserted into the slider 29 to improve the stability of the connection between the second fixing plate 9 and the pressure plate 6. The limiting plate 31 is attached to the outside of the second fixing plate 9 so that the limiting rod 32 is inserted into the limiting groove, which further improves the stability of the second fixing plate 9 at the bottom of the pressure plate 6. When the second fixing plate 9 needs to be replaced, the second electric push rod 30 is activated to retract, no longer limiting the slider 29. Then the limiting plate 31 is moved to drive the limiting rod 32 to separate from the limiting groove, no longer limiting the second fixing plate 9. The second fixing plate 9 is removed from the pressure plate 6 by moving the slider 29, and then the new second fixing plate 9 is installed on the pressure plate 6 for use.

[0049] The present invention also provides a method of using the above-mentioned short pipe machine, comprising the following steps:

[0050] Step 1: Fix the pipe to the top of the mold 3, aligning the pipe with the mold 3. Then, use the push cylinder 10 to move the fixing plate 4 and the mold 3 to the outside of the pipe. Start the clamping cylinder 8 to push the clamping plate 6 and the second fixing plate 9 downwards. The top of the pipe is located inside the installation port in the middle of the second fixing plate 9, thus clamping the pipe.

[0051] Step 2: When the top of the pipe is located on the inner wall of the installation port, start the first electric push rod 17 to move the clamping block 18 to the outside of the pipe and fit against the outside of the pipe to restrict the pipe again. At the same time, start the electric telescopic block 24 to move the grinding block 25 to the top of the pipe. Start the motor 21 to drive the rotating rod 22 to rotate, so that the moving block 23 drives the electric telescopic block 24 and the grinding block 25 to move back and forth to grind the top of the pipe and remove burrs and uneven parts. When the grinding block 25 moves, start the suction pump 27 so that the collection pipe 28 collects the grinding waste into the collection box 26.

[0052] Step 3: After the clamping plate 6 and the second fixing plate 9 fix the pipe in the mold 3, the vacuum bag on the machine body 1 is used to draw air to make the pipe fit the mold 3 and expand the pipe. After the expansion is completed, the core-pulling cylinder 13 is started to drive the unloading shaft 14 to retract. The mold 3 is pulled out from the processed pipe through the fixing welding plate 4, so that the pipe is separated from the mold 3.

[0053] Step 4: When the second fixing plate 9 is damaged due to prolonged pressure, the second electric push rod 30 is activated to retract, no longer restricting the slider 29. Then, the limiting plate 31 is moved to drive the limiting rod 32 to separate from the limiting groove, no longer restricting the second fixing plate 9. The second fixing plate 9 is removed from the pressing plate 6 by moving the slider 29. Then, a new second fixing plate 9 is installed on the pressing plate 6 for use.

[0054] Working principle: In use, the pipe is fixed on the top of the mold 3, aligning the pipe with the mold 3. The push cylinder 10 pushes the fixed welding plate 4 and the mold 3 to move along the support rod 15, causing the mold 3 to move to the outside of the pipe. The clamping cylinder 8 drives the telescopic rod 7 to extend, pushing the clamping plate 6 and the second fixed plate 9 downward. The top of the pipe is positioned within the mounting opening of the second fixing plate 9. The first electric push rod 17 is activated to move the clamping block 18 to the outside of the pipe, so that the arc-shaped side of the clamping block 18 fits against the outside of the pipe, further restricting the pipe. The electric telescopic block 24 is activated to move the grinding block 25 downward, so that the grinding block 25 moves to the top of the pipe and fits against it. The motor 21 is activated to drive the rotating rod 22 to rotate along the inner wall of the fixing groove, so that the moving block 23 moves along the rotating rod 22, and the electric telescopic block 24 drives the grinding block 25 to move back and forth on the top of the pipe to grind the top of the pipe, removing burrs and uneven areas. When the grinding block 25 moves, the suction pump 27 is activated at the same time, so that when the electric telescopic block 24 drives the collection box 26 to move, the collection pipe 28 absorbs the waste after grinding.

[0055] After the clamping plate 6 and the second fixing plate 9 fix the pipe inside the mold 3, the vacuum bag on the machine body 1 is used to draw air to make the pipe fit against the mold 3 and flare the pipe. After flaring, the core-pulling cylinder 13 is activated to drive the unloading shaft 14 to retract. The mold 3 is pulled out from the processed pipe through the fixing welding plate 4, so that the pipe is separated from the mold 3. When the second fixing plate 9 is damaged due to long-term clamping, the second electric push rod 30 is activated to retract and no longer restrict the slider 29. Then the limiting plate 31 is moved to drive the limiting rod 32 to separate from the limiting groove and no longer restrict the second fixing plate 9. The second fixing plate 9 is removed from the clamping plate 6 by moving the slider 29, and then a new second fixing plate 9 is installed on the clamping plate 6 for use.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
