[0002] A straight tube bending and forming device is a device used to process a straight tube into a desired shape. In order to prevent the bent tube from deviating during bending, some straight tube bending and forming devices use I-shaped rollers for guided bending. However, these I-shaped rollers are generally integrally formed and cannot adapt to straight tubes of different sizes, and their applicability is too low.

In the utility model, the first baffle and the second baffle inside the first pulley and the second pulley are extended in length, and the plane where the first baffle and the second baffle intersect with the end face is a structure with an arc, so that the first baffle and the second baffle can fix the processed pipe more firmly, and the problem of the pipe falling off due to the large extrusion force will not occur.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reference Figure 1 - Figure 2 , Figure 4 The utility model provides an embodiment: a straight tube bending and forming device, including a bending and forming device 1, a driving shaft 4 is arranged on the upper surface of the bending and forming device 1, and the driving shaft 4 is controlled to rotate by the bending and forming device 1. When processing the straight tube, it will drive the roller adjustment component 2 to rotate to ensure the smoothness of the straight tube bending. The inner wall of the driving shaft 4 is provided with a card groove 6, and the inner wall of the driving shaft 4 is provided with a disassembly component 5. The upper surface of the disassembly component 5 is provided with a roller adjustment component 2, and the front surface of the bending and forming device 1 is provided with a support component 3. The roller adjustment component 2 includes a roller 1 21, and the lower surface of the roller 1 21 contacts the upper surface of the driving shaft 4. The upper surface of the roller 1 21 is penetrated and slidably connected with a roller 2 22, and the inner wall of the roller 1 21 is provided with a groove 1 26, and the number is multiple groups. The provision of multiple groups of grooves can ensure that the roller 1 21 and the roller 2 22 can be limited and fixed at different connection distances.

[0035] Reference Figure 1 , Figure 3 and Figure 7 The support assembly 3 includes a support shell 31, which is fixedly connected to the front surface of the bending and forming equipment 1. The inner wall of the support shell 31 is slidably connected to a support plate 32. The upper surface of the front end of the support plate 32 is fixedly connected to a support block 33. The upper surface of the support block 33 is provided with rectangular grooves 39 in multiple groups. The inner wall of the rectangular groove 39 is rotatably connected to a roller 34. The roller 34 can reduce the friction when the straight tube moves, thereby reducing labor costs.

[0036] Reference Figure 2 , Figure 5The disassembly assembly 5 includes a card block 51, which contacts the inner wall of the drive shaft 4. The upper surface of the card block 51 is fixedly connected to the lower surface of the roller 21. The left end of the front surface of the card block 51 is fixedly connected with a rubber block 52, which contacts the inner wall of the card slot 6. The rubber block 52 is made of rubber material. The rubber material is selected so that the rubber block 52 has a certain elasticity, which improves the disassembly efficiency of the card block 51 and ensures the stability of the connection between the card block 51 and the drive shaft 4.

[0037] Reference Figure 2 , Figure 4 The left surface of the bottom end of the roller 22 is penetrated by a round rod 24 for sliding connection. The round rod 24 matches the inner wall of the groove 26 to ensure the stability of the connection. The left surface of the round rod 24 contacts the inner wall of the groove 26. The right surface of the round rod 24 is fixedly connected with a push plate 23. The push plate 23 is slidably connected to the inner wall of the roller 22. There are multiple groups of push plates 23, and the multiple groups of push plates 23 are elastically connected by a spring 25. The spring 25 always pushes the multiple groups of push plates 23 to move to both sides through its own elasticity, ensuring that the round rod 24 always contacts the inner wall of the groove 26 without pushing the push plate 23, ensuring the stability of the connection. One end of the push plate 23 is fixedly connected to the right surface of the bottom end of the push plate 23, and the other end of the spring 25 is fixedly connected to the left surface of the multiple groups of push plates 23.

[0038] Reference Figure 3 , Figure 6 A groove three 38 is provided at the rear end of the left surface of the support plate 32. The inner wall of the groove three 38 is elastically connected to the limiting column 35 through a spring two 37. The spring two 37 itself has a certain elasticity to ensure that the limiting column 35 can be quickly reset. The limiting column 35 is slidably connected to the inner wall of the groove three 38. The left surface of the limiting column 35 is an arc-shaped surface, which provides a certain stability between the support shell 31 and the support plate 32, but will not be stuck, and is easy to adjust. One end of the connecting spring two 37 is fixedly connected to the inner wall of the groove three 38, and the other end of the spring two 37 is fixedly connected to the right surface of the limiting column 35. The inner wall of the support shell 31 is provided with grooves two 36 and there are multiple groups of them. The left surface of the limiting column 35 contacts the inner wall of the groove two 36.

[0039] Working principle: When in use, adjust the position of the roller adjustment component 2 through the bending and forming equipment 1, and then put the straight pipe in the middle of the multiple groups of roller adjustment components 2, and start the bending and forming equipment 1 to process the straight pipe. When different sizes need to be processed, you only need to push the multiple groups of push plates 23. The multiple groups of push plates 23 will squeeze the spring 1 25. At the same time, the push plates 23 will drive the round rod 24 to move it away from the inner wall of the groove 1 26. At this time, you can pull the roller 22 to adjust the connection distance between the roller 1 21 and the roller 2 22. When the adjustment is completed, loosen the push plate 23. At this time, the spring 1 25 will push the multiple groups of spring 1 25 to move in the opposite direction through its own elasticity, and the round rod 24 will also be inserted into the inner wall of the groove 1 26. In this way, it can be ensured that the roller 1 21 and the roller 2 22 fit the straight pipes of different sizes to prevent the straight pipe from running off.

[0040] When the roller adjustment assembly 2 needs to be replaced, it is only necessary to pull the roller adjustment assembly 2 upward with force. The roller adjustment assembly 2 will drive the block 51 to move upward, and the rubber block 52 will move upward accordingly. It will be squeezed and deformed by its own elasticity and detach from the inner wall of the slot 6. In this way, the roller adjustment assembly 2 can be removed. When installing, just insert the block 51 into the inner wall of the drive shaft 4. The subsequent structural coordination method is the same as above.

[0041] The connection distance between the support shell 31 and the support plate 32 can be adjusted according to the length of the straight tube to ensure the stability of the support. When adjustment is needed, it is only necessary to pull the support plate 32. At this time, since the front surface of the limit column 35 is an arc-shaped surface, it will be forced to move from the inner wall of the second groove 36 and enter the inner wall of the third groove 38. At the same time, the limit column 35 will squeeze the spring second 37 until the limit column 35 overlaps with another set of grooves two 36. At this time, the spring second 37 will push the limit column 35 to move in the opposite direction and enter the inner wall of the other set of grooves two 36 through its own elasticity. Repeat this process. When the adjustment is completed, stop pulling. When in use, the straight tube is processed and needs to be pushed out. At this time, the roller 34 will roll with it to reduce friction, thereby reducing labor costs.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
