[0028] In order to solve the technical problems in the background art, as shown in Figs. 1-2 The present application provides a technical solution: a seamless pipe bending device, characterized by:
[0029] The fixed seat 1 is the basis of the entire seamless steel pipe bending device, usually made of solid metal material to ensure the stability of the entire device. The fixed seat 1 is provided with the mounting position of the support column 2 at both ends. The support column 2 is vertically fixed to the two ends of the fixed seat 1, and the slide rail 3 is fixedly arranged on the side wall thereof. The slide rail 3 is used to guide the smooth movement of the push plate 6 between the support columns 2. The cross beam 4 is arranged at the upper end of the two support columns 2, used to support the extrusion mechanism 5. The cross beam 4 is usually made of high-strength and wear-resistant material to withstand the force generated by the extrusion mechanism 5 during work. The extrusion mechanism 5 is arranged on the cross beam 4, and a plurality of extrusion mechanisms 5 are arranged in parallel on the cross beam 4. Each extrusion mechanism 5 is designed to be able to apply pressure to the seamless steel pipe to achieve the purpose of bending. The push plate 6 is arranged between the two support columns 2, and the slide plate 6 is provided with a pulley 7 on both sides. The pulley 7 is matched with the slide rail 3, so that the push plate 6 can slide smoothly between the support columns 2. The V-shaped block 8 is arranged above the push plate 6, and a plurality of V-shaped blocks 8 are respectively located at the gap between the extrusion mechanisms 5. The V-shaped block 8 is provided with a limiting hole 9, used to pass through the limiting rod 10. The limiting rod 10 is arranged in parallel with the push plate 6, and each limiting rod 10 passes through the limiting hole 9 of a plurality of V-shaped blocks 8. The main function of the limiting rod 10 is to apply an upward force to the steel pipe. The seamless steel pipe is vertically placed above the limiting rod 10, and is limited by the cooperation with the extrusion mechanism 5 to prevent displacement during bending. The gas cylinder 11 is fixed to the fixed seat 1, and the jacking rod contacts the push plate 6 to drive the push plate 6 to move up and down. The gas cylinder 11 can be electric or pneumatic, providing power as needed.
[0030] In use, the seamless steel pipe is placed on the limiting rod 10 of the V-shaped block 8 to ensure the correct position of the steel pipe. Then, the gas cylinder 11 is started to make the push plate 6 rise, thereby pushing the seamless steel pipe to move to the extrusion mechanism 5. When the seamless steel pipe reaches the position of the extrusion mechanism 5, the extrusion mechanism 5 starts to work, generating a reaction force to extrude the steel pipe and make it bend. When the bending pipe reaches the required angle, stop the work of the gas cylinder 11 to make the push plate 6 descend, thereby taking out the bent seamless steel pipe.
[0031] Further, the extrusion mechanism 5 includes a fastening screw 12, a fixed block 13, a locking block 14, an extrusion wheel 15, a limiting block 16, a spring pin 17, an eccentric wheel 18 and a handle 19. The fastening screw 12 is a fastener for connecting the cross beam 4 and the fixed block 13. By adjusting the fastening screw 12, the position of the fixed block 13 on the cross beam 4 can be fixed or adjusted. The fixed block 13 is fixed on the cross beam 4. The fixed block 13 is provided with a protrusion 20 and a through hole 21, and the through hole 21 is used for penetrating the spring pin 17. The locking block 14 is provided with a groove 22 corresponding to the protrusion 20, and is fixedly connected with the spring pin 17 penetrating the through hole 21. The locking block 14 functions to fix the position of the extrusion wheel 15 and lock when needed. The extrusion wheel 15 is a key component for realizing the bending of the steel pipe, which is connected with a positioning block 24 matched with a V-shaped lug 23. The side wall of the extrusion wheel 15 is provided with an arc-shaped groove 25 for accommodating the steel pipe, and the bending is realized by applying pressure to the steel pipe. The side wall of the fixed block 13 is hinged with a sector-shaped limiting block 16, which can rotate to limit the sliding of the positioning block 24, ensuring the stability of the extrusion wheel 15 during pipe bending. The spring pin 17 is hinged with the eccentric wheel 18 at the top end after penetrating the through hole 21 of the fixed block 13. The spring pin 17 functions to realize the locking and releasing of the extrusion wheel 15 under the operation of the handle 19. One side of the eccentric wheel 18 is connected with the handle 19, and the design of the eccentric wheel 18 enables the rotation of the handle 19 to be converted into the linear motion of the spring pin 17, realizing the locking and releasing. The handle 19 is a component used by the operator to control the locking and releasing of the extrusion wheel 15. By rotating the handle 19, the operator can control the eccentric wheel 18, and then control the locking state of the spring pin 17, realizing the replacement of the extrusion wheel 15, so as to adapt to steel pipes of different diameters.
[0032] It should be noted that the reinforcing sheet 26 is arranged on the bottom surface of the push plate 6. Its main function is to enhance the rigidity and stability of the push plate 6, especially when the lifting rod of the air cylinder 11 applies force, the reinforcing sheet 26 can provide additional support to prevent the push plate 6 from deforming or being damaged. The reinforcing sheet 26 is connected with the lifting rod of the air cylinder 11, which can be connected by welding, bolt connection or other suitable fixing methods. This connection ensures that when the air cylinder 11 drives the push plate 6 to move up and down, the reinforcing sheet 26 can effectively transmit force and reduce the bending or twisting of the push plate 6.
[0033] It is worth noting that the column foot 27 is arranged at both ends of the support column 2. The main role of the column foot 27 is to provide stability and fix the position of the support column 2, while protecting the bottom of the support column 2 from damage. The column foot 27 is provided with a mounting slot 28 for accommodating the support column 2. The shape and size of the mounting slot 28 match the support column 2, ensuring that the support column 2 can be stably installed in the column foot 27. The sidewall of the column foot 27 is provided with a plurality of reinforcing ribs 29. The role of the reinforcing ribs 29 is to enhance the strength and rigidity of the column foot 27, preventing the column foot 27 from deforming or being damaged when subjected to external forces.
[0034] It should be noted that two limiting blocks 16 are arranged on both sides of the hinge shaft of the fixing block 13 and the limiting block 16. This layout makes both sides of each positioning block 24 limited by the limiting block 16, thereby enhancing the stability and accuracy of the positioning block 24 during the bending process. Two limiting blocks 16 are respectively located on both sides of the positioning block 24, ensuring that the positioning block 24 is firmly limited in the predetermined position during the bending process, preventing it from being displaced due to the pushing force of the steel pipe.
[0035] Further, a plurality of limiting rods 10 are symmetrically arranged on the V-shaped block 8, which helps to maintain the stability and balance of the seamless steel pipe during the bending process. By symmetrical arrangement, it can ensure that the steel pipe is uniformly stressed in the V-shaped block 8, avoiding bending errors caused by uneven stress.
[0036] It is worth noting that a plurality of limiting holes 9 are arranged along the length direction of the V-shaped block 8, which are uniformly distributed on the V-shaped block 8 for adjusting the position of the limiting rod 10. This layout provides flexibility, allowing the position of the limiting rod 10 to be adjusted according to the diameter of the steel pipe and the bending requirements. The main function of the limiting hole 9 is to provide multiple mounting positions for the limiting rod 10, so that the limiting rod 10 can pass through different limiting holes 9 as needed to fix the steel pipe. This can adapt to different bending requirements, improving the adaptability and flexibility of the device.
[0037] It should be noted that the arc-shaped slot 25 is arranged on the sidewall of the positioning block 24, which is designed to match the outer diameter of the seamless steel pipe in shape and size. This design ensures that the steel pipe can be stably placed in the positioning block 24 during the bending process, reducing the possibility of sliding or displacement. The main function of the arc-shaped slot 25 is to provide a slot that matches the outer diameter of the steel pipe, so that the steel pipe can tightly fit the positioning block 24 during the bending process, thereby improving the accuracy and quality of the bending. The size of the arc-shaped slot 25 is accurately designed according to the outer diameter of the steel pipe, ensuring that the steel pipe can perfectly fit into the arc-shaped slot 25. This matching can be one-to-one or universal design to adapt to a certain range of steel pipe diameters.
[0038] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary and that changes can be made in detail without departing from the principles and spirit of the application. The scope of the application is therefore defined by the appended claims and their equivalents.
