Description

Technical Field

[0001] This utility model relates to the field of pipe shaping technology, and in particular to a special machine for shaping airtight pipe bends. Background Technology

[0002] In modern industrial systems, pipelines, as key carriers for fluid transmission, are widely used in petrochemical, energy and power, building water supply and drainage and other fields. Since pipeline systems need to meet the fluid transmission requirements under different working conditions, such as adapting to complex spatial layouts and withstanding specific pressures and temperatures, the shaping and sealing effects of pipeline components have become the core links to ensure their performance. The shaping process aims to make pipeline components achieve the preset shape, size and structural strength through physical deformation, while airtightness testing is a key detection method to verify whether the pipeline can operate safely.

[0003] The shaping process of pipe components typically involves multiple intricate steps. Hydraulic equipment is used to apply external force to the pipe, causing it to undergo plastic deformation. The overall sealing performance of the pipe is then verified through an airtightness test.

[0004] Traditional equipment often employs single-process segmented operation with a high degree of human involvement. From parts placement and shaping to airtightness testing, it relies on manual operation, resulting in low work efficiency. Furthermore, the inconsistent testing accuracy is caused by human error. In addition, the unloading process after shaping is cumbersome, leading to low production efficiency and reducing the overall efficiency and product quality of pipeline shaping.

[0005] Therefore, it is necessary to provide a special machine for forming airtight pipe bends to solve the above-mentioned technical problems. Utility Model Content

The rotating rod 55 is rotatably installed on one side of the rotating block 54. The two rocker arms 56 are respectively fixedly installed on both sides of the outer surface of the rotating rod 55.

[0037] The recycling device 6 is located on one side of the descrambling device 5. The top of the mounting plate 3 is provided with pushers 4 on both sides. One side of one of the pushers 4 is provided with an airtight machine 11. The pusher 4 includes a mounting platform 41, a first cylinder 42 and a sleeve 43. The mounting platform 41 is fixedly installed on the top of the mounting plate 3. The first cylinder 42 is fixedly installed on the top of the mounting platform 41. The sleeve 43 is fixedly connected to the end of the output shaft of the first cylinder 42.

[0038] Guide blocks 9, two guide blocks 9 are respectively fixedly installed on both sides of the top middle of the mounting platform 41, and grippers 10 are slidably installed on both sides of the surface of the guide blocks 9. The third cylinder 8 is fixedly installed on the bottom of the mounting plate 3.

[0039] Pipe 13, which is disposed between the two thrusters 4.

[0040] The recycling device 6 includes a feeding box 61 and an inclined guide plate 62. The feeding box 61 is fixedly installed on the top of the support block 51, and the inclined guide plate 62 is rotatably installed on one side of the outer surface of the feeding box 61.

[0041] The surface of the workbench 1 is equipped with a controller 7.

[0042] The output shaft end of the third cylinder 8 is fixedly connected to one of the propellers 4, and the third cylinder 8 pushes one of the propellers 4 to slide, causing the tube 13 to bend.

[0043] The two grippers 10 on the surface of the guide block 9 can slide closer to or further away from each other via the lifting member.

[0044] Under normal circumstances, the output shaft of the second cylinder 52 pulls the connecting block 53 upward, the connecting block 53 drives the rotating block 54 upward through the rotating shaft, the rotating block 54 drives the rotating rod 55 and the rocker arm 56 upward, so that the rocker arm 56 moves upward to hold the pipe 13, the rotating rod 55 rotates through the rotation of the motor output shaft, so that the rocker arm 56 flips and guides the pipe 13 into the inclined guide plate 62.

[0045] Two opposing thrusters 4 form a set of equipment. Two guide blocks 9 and grippers 10 are installed between the two opposing thrusters 4. An airtightness tester 11 is installed on the surface of one of the thrusters 4 to test the airtightness of the pipe fitting 13. A recycling device 6 and a material removal device 5 are installed on one side of the thruster 4, thus forming a complete set of equipment. Multiple sets of complete equipment are equidistantly arranged on the surface of the mounting plate 3.

[0048] The working principle of the special machine for shaping airtight pipes provided by this utility model is as follows:

[0049] During operation, the welded pipe fitting 13 is first manually inserted into the sleeves 43 of the front and rear pushers 4. The start switch is pressed by the controller 7, and the output shafts of the first cylinders 42 of the front and rear pushers 4 move closer to each other. The push sleeves 43 and pipe fitting 13 are shaped and sealed. The two grippers 10 on the guide block 9 are also pushed by the cylinder to clamp the pipe fitting 13. At this time, the airtightness tester 11 will pressurize to 175KPa and test for 20 seconds. After the test is successful, the green light and buzzer will sound an alarm indicating OK. If the airtightness test is unsuccessful, the buzzer will sound an alarm indicating NG and the red light will light up. The parts can only be taken out by manually unlocking with fingerprint.

[0050] After the test, the output shaft of the third cylinder 8 moves to push one of the pushers 4. The pusher 4 drives one end of the pipe 13 to bend, and the pipe 13 is bent. After the bending is completed, the sleeve 43 of the moving pusher 4 moves away from the pipe 13. Then the two grippers 10 automatically release, the third cylinder 8 resets, and the bent pipe falls onto the surface of the rocker arm 56. The rotating rod 55 rotates and drives the rocker arm 56 to flip. The flipped rocker arm 56 guides the bent pipe into the surface of the inclined guide plate 62 and rolls it into the feeding box 61 for feeding.

This device has a simple structure, strong practicality, and low manual intervention. The shaping, airtightness testing, and bending of the pipe fitting 13 can all be automated, improving work efficiency and production efficiency, and improving the overall efficiency and product quality of pipe shaping and processing.

[0054] Second Embodiment

[0056] Specifically, the difference in the second embodiment of this application regarding the special machine for shaping airtight pipes is that a vibration device 12 is provided on one side of the surface of the mounting plate 3 and at the bottom of the inclined guide plate 62.

[0057] The fixing base 121 is fixedly connected to the surface of the mounting plate 3 by bolts, and the striking protrusion 142 is made of rubber.

[0058] The striking block 142 is made of rubber and can deform when squeezed. The striking block 142 rotates with the rotating column 123.

[0059] The working principle of the special machine for shaping airtight pipes provided by this utility model is as follows:

[0060] During operation, the output shaft of the drive motor 122 first rotates, causing the rotating column 123 and the striking protrusion 142 to rotate. The striking protrusion 142 intermittently strikes and squeezes the inclined guide plate 62, causing the inclined guide plate 62 to vibrate and bend the surface of the pipe 13.

[0062] Beneficial effects:

[0063] This utility model provides a special machine for shaping airtight pipes.

This device has a simple structure and strong practicality. It can make it easier to shake off the bent pipe fittings 13 by vibrating the inclined guide plate 62, thereby improving the feeding efficiency.
