Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending, and specifically relates to a pipe bending device. Background Technique

[0002] In the process of pipe processing, it is necessary to bend the pipe into various angles. A bending machine is a professional bending device, mainly used for bending various metal pipes; the bending mechanism is the main component to realize the angle and radian change of the pipe, and its bending principle is based on the action of bending force and bending moment.

[0003] The utility model patent with the authorization announcement number CN214263387U discloses a pipe bending device for high-alloy steel furniture. The pipe bending device for high-alloy steel furniture is provided with a machine box. On the left side of the machine box, there is a manual bending mechanism, and on the right side, there is a heating structure and an automatic bending module. Inside the machine box, there are a driving mechanism and a transmission mechanism. The automatic bending module is provided with a rotating shaft and a retaining column. A turntable is fixedly connected to the rotating shaft. A number of positioning grooves are linearly arranged on the turntable. The retaining column can be inserted into the positioning groove and fixed on the turntable; on the right end above the machine box, there is a retaining column II. The rotating shaft is connected to the transmission mechanism. The driving mechanism can drive the transmission mechanism to rotate and then drive the rotating shaft to make a rotational motion. When using the device for automatic bending, place the steel pipe between the rotating shaft and the retaining column on the turntable. At this time, start the motor to drive the turntable to rotate. The steel pipe is bent under the action of the three forces of the rotating shaft, the retaining column, and the retaining column II. The bending angle of the steel pipe is controlled by the rotation period of the motor; insert the retaining column into the positioning grooves at different positions to adapt to steel pipes of different sizes. By adjusting the bolts, the extending length of the strip can be adjusted, thereby changing the bending position. Through the cooperation of the automatic bending module, the driving mechanism and the transmission mechanism, automatic bending is realized, and the problem that the existing technology equipment is difficult to bend steel pipes with larger sizes is solved. Because the arm strength of the user is very limited, and in the process of manual bending, it is easy to occur that the pipe is bent too much or too little. Relying on manual control of bending, the bending defective rate is high and the efficiency is low.

[0004] Although the pipe bending device for high-alloy steel furniture realizes automatic bending through the automatic bending module and improves the efficiency of steel pipe bending, there are still the following problems in the actual use process of this device. Specifically speaking: This device bends the steel pipe by applying the acting forces of the set rotating shaft, retaining column, and retaining column II. However, the steel pipe is subjected to a large force during the bending process, and the steel pipe itself lacks an effective fastening or limiting structure. Therefore, it is very easy for the steel pipe to pop out during the bending process, which poses a great threat to the safety of the staff. In view of this, we propose a pipe bending device.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0028] This embodiment provides a technical solution:

[0029] Please refer to Figures 1-6 As shown, a pipe bending device includes a base 1, an anti - ejection part 2, and an electric cylinder 14.

[0030] On one side of the top of the base 1, a side plate 10 is provided.

[0031] The anti - pop - out part 2 is used to prevent the pipe from popping out during the bending process. The anti - pop - out part 2 includes a bracket 20. The bracket 20 is installed on the top of the base 1. The bracket 20 is used to limit the pipe to prevent it from popping out. The top end of the bracket 20 is bent towards the side plate 10, and multiple connecting shafts 211 are rotatably installed between the bent plate surface of the bracket 20 and the base 1. Each connecting shaft 211 is distributed at both ends of the bracket 20, and a support wheel 21 is arranged on each connecting shaft 211.

[0032] The electric cylinder 14 is installed on the side plate 10. The telescopic shaft end of the electric cylinder 14 faces the bracket 20 and is provided with a connecting plate 11. On the side of the connecting plate 11 facing the bracket 20, a bending head 12 is provided.

[0033] Preferably, the connecting plate 11 and the bending head 12 are of an integrally formed structure, and both the connecting plate 11 and the bending head 12 are made of galvanized steel. The integrally formed connecting plate 11 and bending head 12 have better connection strength, ensuring the stability of the connecting plate 11 and the bending head 12. The galvanized steel material has the advantages of corrosion resistance and high strength, ensuring the service life of the connecting plate 11 and the bending head 12 and the bending effect on the pipe.

[0034] Preferably, a guide rod 13 is installed on the side of the connecting plate 11 away from the bending head 12. The guide rod 13 is slidably connected to the side plate 10. The setting of the guide rod 13 plays a guiding role in the horizontal movement of the connecting plate 11, ensuring the smoothness and stability of the horizontal movement of the connecting plate 11 and the bending head 12.

[0035] Furthermore, cross beams 22 extending towards the side plate 10 are respectively arranged on both sides of the bent end of the bracket 20. A support plate 23 is connected between the distal ends of the cross beams 22 and the base 1. A strip - shaped groove 221 is formed in the cross beam 22. A connecting rod 24 is installed in the strip - shaped groove 221. A slider 26 is slidably installed on the connecting rod. A spring 25 is sleeved on the connecting rod 24. The two ends of the spring 25 are respectively connected to the slider 26 and one end of the strip - shaped groove 221. An auxiliary wheel 27 is rotatably installed at the bottom of the slider 26.

[0036] In this embodiment, the cross beam 22 and the support plate 23 are of an integrally formed structure, and the cross beam 22 and the support plate 23 are respectively fixedly connected to the bracket 20 and the base 1 by bolts. The integrally formed cross beam 22 and support plate 23 have better connection strength, ensuring the connection stability of the cross beam 22 and the support plate 23, and the bolt - fixing method ensures the installation reliability of the cross beam 22 and the support plate 23.

[0037] Preferably, two guiding grooves 15 parallel to the strip-shaped groove 221 are formed in the top of the base 1, and a guiding shaft 271 is arranged at the bottom end of the auxiliary wheel 27. The guiding shaft 271 is slidably connected with the corresponding guiding groove 15. The arrangement of the guiding shaft 271 and the guiding groove 15 plays a further guiding role in the movement of the auxiliary wheel 27, ensuring the smooth and stable movement of the auxiliary wheel 27.

[0038] Preferably, the overall shapes of the auxiliary wheel 27 and the supporting wheel 21 are both cylindrical, and both the auxiliary wheel 27 and the supporting wheel 21 are made of galvanized steel. The cylindrical design is conducive to bending the pipe, and the galvanized steel material has the advantages of corrosion resistance and high strength, thus ensuring the stable bending operation of the auxiliary wheel 27 and the supporting wheel 21 on the pipe.

[0039] It should be added that a limiting block is coaxially fixed at the end of the guide rod 13 in this embodiment. The diameter of the limiting block is larger than that of the guide rod 13. The limiting block can prevent the guide rod 13 from detaching from the side plate 10, ensuring the stable movement of the connecting plate 11.

[0040] It is worth noting that the electric cylinder 14 involved in this embodiment is an existing conventional technology and will not be elaborated here.

[0041] During specific use, the user first passes the pipe through the side close to the side plate 10 of the bracket 20 and makes the pipe pass between the auxiliary wheel 27 and the supporting wheel 21. At this time, the pipe is clamped by the auxiliary wheel 27 and the supporting wheel 21. Then the user starts the power supply of the electric cylinder 14, and the electric cylinder 14 starts to work. The piston rod of the electric cylinder 14 extends and drives the connecting plate 11 and the bending head 12 to move horizontally. The bending head 12 simultaneously presses against the pipe and bends it. As the bending head 12 advances, the pipe is bent. As the pipe gradually bends, the two ends of the pipe push the auxiliary wheel 27 to move along the cross beam 22, and the auxiliary wheel 27 rotates synchronously. At this time, the auxiliary wheel 27 drives the slider 26 to slide along the connecting rod 24, and the spring 25 is compressed. When the pipe is bent to an appropriate angle, the user stops the power supply of the electric cylinder 14.
