Description

Technical Field

[0001] This utility model relates to the field of pipe bending technology, specifically to a pipe bending machine for building construction. Background Technology

[0002] In construction, especially in the construction of lines and pipelines, metal pipes are often used. To meet construction needs, pipes usually need to be bent at angles using a bending machine. For example, in residential construction, commercial real estate and infrastructure construction, pipes need to be bent to adapt to different building structures and pipeline layout requirements. With the continuous expansion of global manufacturing and the continuous development of the construction industry, the demand for pipe bending machines is also increasing.

[0003] Some traditional pipe bending machines require manual removal of the bent pipe material during use, which reduces bending efficiency. Furthermore, some bending machines do not allow for quick adjustment of the bending position of the pipe material, affecting bending processing requirements.

[0004] During construction, the inner diameter of pipes may vary slightly. However, existing bending machines do not have an adjustment function, which may result in the inability to insert pipes with larger inner diameters. Utility Model Content

[0005] Given that the inner diameter of pipes may vary slightly during construction, and existing bending machines do not have an adjustment function, they will have the disadvantage of being unable to insert and place pipes with larger inner diameters.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a pipe bending machine for construction engineering, comprising: a mounting base plate and rectangular sleeves, a pair of rectangular sleeves fixedly mounted on the upper surface of the mounting base plate, a circular plate penetrating through the vertical surface of the rectangular sleeves, an L-shaped storage sleeve fixedly mounted on the vertical surface of the circular plate, an L-shaped plate slidably connected to the inner ring of the L-shaped storage sleeve, a rectangular mounting plate fixedly connected to the opposite vertical surfaces of the pair of rectangular sleeves, an L-shaped block penetrating through the vertical surface of the rectangular mounting plate, a rectangular strip penetrating through the L-shaped block, a circular ring sleeve fixedly mounted on the vertical surface of the rectangular strip, threaded rods fitted into the inner rings of the pair of circular ring sleeves, and gear columns penetrating through the rods of the pair of threaded rods.

[0009] As a preferred embodiment of the pipe bending machine for construction engineering described in this utility model, a rectangular sliding groove is provided on the bottom surface of the rectangular moving groove, and a pair of rectangular moving plates are also provided inside the rectangular sliding groove. Ball bearings are also provided on the rectangular moving plates, and a U-shaped connecting sleeve is fixedly installed on the upper surface of the rectangular moving plates. A rectangular limiting plate is fixedly connected to the vertical surface inside the U-shaped connecting sleeve.

[0010] In a preferred embodiment of the pipe bending machine for construction engineering described in this utility model, a T-shaped moving block is slidably connected to the inner ring of the U-shaped connecting sleeve.

[0022] 42342 To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example 1:

[0025] Reference Figure 1-5The first embodiment of this utility model discloses a pipe bending machine for construction engineering, comprising: a mounting base plate 1 and rectangular sleeves 2. A pair of rectangular sleeves 2 are fixedly installed on the upper surface of the mounting base plate 1. A circular plate 3 is connected through the vertical surface of the rectangular sleeves 2. An L-shaped storage sleeve is fixedly installed on the vertical surface of the circular plate 3. An L-shaped plate is slidably connected to the inner ring of the L-shaped storage sleeve. A rectangular mounting plate 4 is fixedly connected to the opposite vertical surfaces of the pair of rectangular sleeves 2. An L-shaped block 5 is provided through the vertical surface of the rectangular mounting plate 4. A rectangular strip 6 is provided through the L-shaped block 5. A circular ring is fixedly installed on the vertical surface of the rectangular strip 6. A threaded rod 7 is fitted into the inner ring of the pair of circular rings. A gear column 8 is provided through the rod body of each pair of threaded rods 7.

[0026] A pair of gears 8 are connected to the same synchronous belt through meshing teeth. A torsion bar 9 is fixedly connected to the cross section of one of the threaded rods 7. A rubber anti-slip layer 10 is installed on the outer ring of the torsion bar 9. A pair of symmetrical L-shaped grooves 11 are opened on the vertical surface of the L-shaped block 5. A rectangular moving block 12 is slidably connected to the bottom surface inside the L-shaped groove 11. An L-shaped plug rod 13 is inserted through the vertical surface of the rectangular moving block 12. A circular ring is rotatably connected to the body of the L-shaped plug rod 13. A counterweight is fixedly connected to the arc surface of the circular ring. A rectangular moving groove 14 is opened on the vertical surface of the L-shaped plug rod 13. An L-shaped moving rod is inserted into the vertical surface of the T-shaped moving block 17.

[0027] A rectangular sliding groove is provided on the bottom surface inside the rectangular moving groove 14. A pair of rectangular moving plates are also provided inside the rectangular sliding groove. Ball bearings are also provided on the rectangular moving plates. A U-shaped docking sleeve 15 is fixedly installed on the upper surface of the rectangular moving plates. A rectangular limiting plate 16 is fixedly connected to the vertical surface inside the U-shaped docking sleeve 15. A T-shaped moving block 17 is slidably connected to the inner ring of the U-shaped docking sleeve 15. A rectangular plate is also provided on the vertical surface of the T-shaped moving block 17 away from the rectangular limiting plate 16. A cylindrical telescopic sleeve 18 is rotatably connected to the vertical surface of the rectangular plate. A docking block 19 is inserted into the inside of the rectangular moving groove 14. A connecting plate is fixedly provided on the vertical surface of the docking block 19. A memory spring 20 is also provided on the vertical surface of the connecting plate.

[0028] When using the device, first rotate the ring sleeve on the L-shaped plug rod 13. Because the counterweight is fixedly connected to the arc surface of the ring sleeve, the counterweight is brought close to the L-shaped groove. Then, simply move a pair of L-shaped moving rods to bring them closer together. The L-shaped moving rod is inserted into the vertical surface of the T-shaped moving block 17, and the T-shaped moving block 17 is slidably connected to the inner ring of the U-shaped docking sleeve 15. A rectangular plate is also provided on the vertical surface of the T-shaped moving block 17 away from the rectangular limiting plate 16. The cylindrical telescopic sleeve 18 is rotatably connected to the vertical surface of the rectangular plate. Therefore, when a pair of L-shaped moving rods are close together, the pair of rectangular limiting plates 16 will not block the L-shaped plug rod 13. The L-shaped plug rod 13 will rotate under the action of the counterweight. Then, hold the L-shaped plug rod 13 by hand and push it. Because the vertical surface of the L-shaped plate has a docking hole, after the L-shaped plug rod 13 has moved, it will be inserted into the interior of the L-shaped plate.

[0029] After the insertion is completed, rotate the torsion bar 9 to make a pair of threaded rods 7 rotate, thereby moving the L-shaped block 5 to adapt to pipes with different inner diameters.

[0030] Example 2:

[0031] Reference Figure 2 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a motor driver 21 is also provided on the upper surface of the mounting base plate 1, an external controller 22 is also provided on the upper surface of the mounting base plate 1, a mounting frame is also provided on the vertical surface inside the rectangular sleeve 2, a drive motor 23 is provided on the upper surface of the mounting frame, and a connecting wire 24 is also provided on the external controller 22.

[0032] Jihai G32R501 Low-Voltage Sensorless Dual Motor Reference Solution: The main control chip uses the G32R501 real-time control MCU, supporting sensorless FOC control of dual motors. Under single-core conditions, it can perform complete current loop control of both motors in just 24.8μs. This solution has 16 PWM channels, offering high multi-channel synchronization performance. Independent control of the two motors can be achieved through the control of the PWM channels, enabling simultaneous rotation of both motors or rotation of a single motor.

[0033] Before using the equipment, determine whether the pipe needs to be bent at both ends or at one end, and adjust the mode of the motor driver 21 accordingly. The two motors can be independently controlled by controlling the PWM channel, so that the two motors can rotate at the same time or a single motor can rotate. Then, you can operate according to the steps in Example 1.

[0034] The remaining structure is the same as that in Example 1.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
