Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending machine heads, in particular to a rotary pipe bending machine head. Background Art

[0002] Pipe bending machines can be broadly categorized as CNC and hydraulic. These machines are primarily used for pipe laying and repair in power construction, highway and railway construction, boilers, bridges, ships, furniture, and interior design. They offer multiple functions, a rational structure, and simple operation. In addition to bending pipes, these machines can also utilize the cylinder as a hydraulic jack. Compared to CNC pipe bending equipment, these machines are more affordable and easier to use, making them a leading player in the domestic pipe bending market.

[0003] After searching, an existing patent (publication number: CN 219253752 U) discloses a rotary pipe bending machine head, which relates to the technical field of pipe bending machines. It includes a pipe bending machine head body and a first slide rail. Two first slide rails are fixedly connected to one side of the pipe bending machine head body, and a clamping structure. The clamping structure includes a stopper. The bottom of the stopper is fixedly connected to a lower base. The top of the lower base is fixedly mounted with a second slide rail. The outer surface of the second slide rail is slidably connected to a second pipe bending mold. In the utility model, in order to avoid the inconvenience of disassembly and assembly caused by bolt connection when replacing the pipe bending mold, it is installed by a slide rail instead. A stopper is provided at one end of the slide rail and a limiting hole is provided at the other end. The pipe bending mold is also provided with a limiting hole and a stop bolt.

[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0026] A preferred embodiment of a rotary pipe bending machine head provided by the present invention is as follows: Figures 1 to 5 As shown: A rotary pipe bending machine head, including a machine head body 1, the top of the machine head body 1 is fixedly connected to a fixing column 2, the top of the fixing column 2 is embedded with a support rod 3, the side of the support rod 3 is penetrated by a fixing bolt 4, the top of the support rod 3 is fixedly connected to a first mold 5, the top of the machine head body 1 is located on the side of the first mold 5 and is provided with a clamping mechanism 6, the machine head body 1 includes a mounting plate 11, the back of the mounting plate 11 is fixedly connected to a mounting column 12, the surface of the mounting plate 11 is rotatably connected to an electric shaft body 13, and the surface of the electric shaft body 13 is fixedly connected to a rotating plate 14.

[0027] In this embodiment, two groups of fixed columns 2, support rods 3, fixing bolts 4 and first molds 5 are respectively provided, and the two groups of fixed columns 2 are respectively located at the top and bottom of the electric shaft body 13. By setting two groups of fixed columns 2, support rods 3, fixing bolts 4 and first molds 5, when the bending machine drives the head body 1 to rotate, the two groups of fixed columns 2, support rods 3, fixing bolts 4 and first molds 5 can still cooperate with each other to bend the pipe.

[0028] In this embodiment, circular grooves matching the two groups of support rods 3 are respectively opened on the top and bottom of the two groups of fixing columns 2, and the two groups of support rods 3 are respectively embedded in the circular grooves of the two groups of fixing columns 2. The two groups of support rods 3 are respectively embedded in the circular grooves of the two groups of fixing columns 2, so that the fixing grooves on the sides of the two groups of support rods 3 correspond to the fixing grooves on the sides of the two groups of fixing columns 2.

[0029] In this embodiment, the sides of the two groups of fixing columns 2 and the two groups of support rods 3 are provided with fixing grooves matching the fixing bolts 4, and the two groups of fixing bolts 4 respectively penetrate the fixing grooves on the sides of the two groups of fixing columns 2 and the two groups of support rods 3. When the fixing grooves on the sides of the two groups of support rods 3 correspond to the fixing grooves on the sides of the two groups of fixing columns 2, the two groups of fixing bolts 4 are respectively penetrated through the fixing grooves on the sides of the two groups of support rods 3 and the two groups of fixing columns 2, and the two groups of fixing bolts 4 are tightened to connect the two groups of support rods 3 and the two groups of fixing columns 2, thereby connecting the first mold 5 and the electric shaft body 13.

[0030] In this embodiment, four groups of clamping mechanisms 6 are provided, and the four groups of clamping mechanisms 6 are respectively located at the top and bottom of the mounting plate 11 and the rotating plate 14. By providing four groups of clamping mechanisms 6, the pipeline can be well clamped and positioned, thereby preventing the pipeline from escaping from the inside of the first mold 5 during bending, so as to ensure the bending effect. Example 2

[0031] On the basis of Example 1, a preferred embodiment of a rotary pipe bending head provided by the present invention is as follows: Figures 1 to 5 As shown: the clamping mechanism 6 includes a screw rod 61, a servo motor 62, a slide 63 and a second mold 64. The top of the rotating plate 14 is rotatably connected to the screw rod 61, the side of the screw rod 61 is fixedly connected to the servo motor 62, the surface of the screw rod 61 is threadedly connected to the slide 63, and the top of the slide 63 is fixedly connected to the second mold 64.

[0032] In this embodiment, the top and bottom of the mounting plate 11 and the rotating plate 14 are provided with transverse grooves matching the slide plates 63. Four groups of slide plates 63 are embedded in the transverse grooves at the top and bottom of the mounting plate 11 and the rotating plate 14 and are slidably connected to the mounting plate 11 and the rotating plate 14. The servo motor 62 is started to drive the screw rod 61 to rotate clockwise. Because the slide plate 63 is engaged with the screw rod 61, when the screw rod 61 rotates, it will drive the slide plate 63 to slide to the left in the slide groove at the top of the mounting plate 11. At this time, the second mold 64 fixedly connected to the slide plate 63 will move to the left accordingly. When the second mold 64 moves to fit the pipe, the pipe can be positioned.

[0033] The working principle and usage process of the present invention are as follows: first, the mounting column 12 is installed at the output end of the bending machine to connect the machine head body 1 with the bending machine, and then, the two groups of support rods 3 are respectively embedded in the circular grooves of the two groups of fixing columns 2, so that the fixing grooves on the sides of the two groups of support rods 3 correspond to the fixing grooves on the sides of the two groups of fixing columns 2. At this time, the two groups of fixing bolts 4 are respectively passed through the fixing grooves on the sides of the two groups of support rods 3 and the two groups of fixing columns 2, and the two groups of fixing bolts 4 are tightened to connect the two groups of support rods 3 and the two groups of fixing columns 2, thereby connecting the first mold 5 and the electric shaft body 13. Subsequently, the pipe is clamped by the bending machine, and then the bending machine is started to move the pipe to the inside of the first mold 5. Subsequently, the servo motor 62 is started to drive the screw rod 61 to rotate clockwise. Because the slide plate 63 is engaged with the screw rod 61, when the screw rod 61 rotates, it will drive the slide plate 63 When the second mold 64 moves to fit the pipe, the pipe can be positioned. Subsequently, the second mold 64 of the clamping mechanism 6 on the top of the rotating plate 14 is also fitted with the pipe through the same operation. At this time, the bending machine is started to cooperate with the head body 1 to bend the pipe, thereby preventing the pipe from escaping from the first mold 5 during bending to ensure the bending effect. After bending, if the first mold 5 needs to be replaced, the fixing bolt 4 can be directly loosened and removed, and the fixing column 2 and the support rod 3 can be separated from each other, thereby realizing the disassembly of the first mold 5, thereby facilitating the installation and disassembly of the first mold 5, thereby preventing the first mold 5 from scratching the pipe due to damage, thereby ensuring the bending effect.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
