[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0026] Reference Figures 1-4 A belling machine with adjustable outer diameter includes an operating table 1. A clamping mechanism for fixing the pipe to be processed is provided on one side of the upper end of the operating table 1. The clamping mechanism includes two parallel supporting rollers 10. A gap is left between the two supporting rollers 10. The ends of the supporting rollers 10 are both mounted on a first fixing seat 11. The first fixing seat 11 is fixed on the operating table 1 and is used to place the pipe with the belled end.
[0027] like Figure 3 and Figure 4As shown, a pressure roller 12 is provided parallel to the support roller 10, and the end of the pressure roller 12 is fixed on the second fixed seat 15, and the second fixed seat 15 is fixed on the first support plate 19, and a second support plate 13 is provided above the first support plate 19, and a second linear drive module 14 is vertically installed on the top of the second support plate 13, and the second linear drive module 14 is installed on a U-shaped frame 21 with an opening downward, and the bottom of the U-shaped frame 21 is fixed to the operating table 1. In actual use, the second linear drive module 14 is one of a hydraulic cylinder, an electric push rod, and a cylinder. When the second linear drive module 14 is operated, the pressure roller 12 can be pushed down and pressed on the pipe placed on the support roller 10, thereby clamping and fixing the pipe.
[0028] As the pressure roller 12 presses on the pipe, Figure 4 As shown, a number of spaced-apart sleeves 17 are provided between the first support plate 19 and the second support plate 13. The sleeve 17 is vertically fixed to the bottom of the second support plate 13, and a telescopic shaft 16 is built into the bottom of the sleeve 17. The bottom of the telescopic shaft 16 is fixed to the first support plate 19, and a compression spring 18 is sleeved on the telescopic shaft 16. One end of the compression spring 18 is fixed to the first support plate 19 and the other end is fixed to the sleeve 17. After the pressure roller 12 contacts the pipeline, it can continue to drive the second linear drive module 14, so that the telescopic shaft 16 retracts into the sleeve 17 under the action of the reaction force of the pipeline on the pressure roller 12, thereby compressing the compression spring 18 and providing elastic force to the pressure roller 12, so that the pipeline can be more firmly placed between the pressure roller 12 and the support roller 10 under the action of the elastic force.
[0029] It should be noted that the outer surface of the pressure roller 12 and the outer surface of the support roller 10 are wrapped with anti-slip rubber sleeves to increase the friction when the pressure roller 12 and the support roller 10 contact the pipeline, and further improve the stability of the pipeline between the support roller 10 and the pressure roller 12.
[0030] Furthermore, at least one second guide shaft 20 is provided parallel to the side of the second linear drive module 14. One end of the second guide shaft 20 is fixed on the second support plate 13 and the other end slides through the U-shaped frame 21, providing a guiding effect on the lifting and lowering of the pressure roller 12, thereby improving the lifting and lowering stability of the pressure roller 12.
[0031] After the pipe is fixed, Figure 1 and Figure 2 As shown, a flaring mechanism for flaring the pipe to be processed is provided at the other end of the operating table 1. The flaring mechanism includes a mounting plate 5. A motor for driving the mounting plate 5 to rotate is coaxially mounted on a side of the mounting plate 5 away from the clamping mechanism. The motor is provided in a motor box 4 and provides power for the rotation of the mounting plate 5.
[0032] The motor box 4 is mounted on the fixing frame 27, and the first linear drive module 2 is mounted on the fixing frame 27, the first linear drive module 2 is fixed on the support frame 3, and the support frame 3 is fixed on the operating table 1; at least two flaring tools 6 are installed at intervals along the edge of the other side of the mounting plate 5, and the flaring tool 6 is fixed to the mounting plate 5 by fasteners. When in use, the fasteners are bolts, so that the flaring tool 6 can be detachably mounted on the mounting plate 5, so that according to the required flaring diameter of the pipe to be processed, the flaring tool 6 with a suitable outer diameter can be taken and installed on the mounting plate 5. As the motor in the motor box 4 drives the mounting plate 5, the corresponding flaring tool 6 can be cut to the position corresponding to the pipe, thereby performing the flaring operation; in actual use, the first linear drive module 2 is a hydraulic cylinder. After the flaring tool 6 is switched, the first linear drive module 2 will push the flaring tool 2 close to the pipe until the flaring tool 2 is inserted into the pipe, thereby performing the corresponding flaring on the pipe under the hydraulic drive of the first linear drive module 2.
[0033] In order to ensure the stability of the mounting plate 5 during rotation, Figure 1 As shown, an annular slide rail 7 is coaxially installed on the side of the mounting plate 5 close to the motor box 4, and a slider is slidably installed on the slide rail 7, and the slider is connected to the fixing frame 27 through a connecting rod 8, which provides guidance for the rotation of the mounting plate 5 and provides support for the mounting plate 5, so that the mounting plate 5 is stabilized during the rotation process; in actual use, the connecting rod 8 corresponds to the flaring tool 6 corresponding to the pipe, so that the flaring tool 6 can be provided with targeted support during the process of inserting the flaring tool 6 into the pipe, so as to prevent the mounting plate 5 from being bent and damaged due to the reaction force exerted on the flaring tool 6.
[0034] Furthermore, at least one first guide shaft 9 is provided parallel to the side of the first linear drive module 2, one end of the first guide shaft 9 is fixed on the fixing frame 27, and the other end of the first guide shaft 9 slides through the support frame 3 to provide guidance for the movement of the flaring tool 6.
[0035] It should be noted that if Figure 3 and Figure 4As shown, U-shaped seats 23 are symmetrically provided on both sides of the U-shaped frame 21, and the U-shaped seats 23 are located on both sides above the support roller 10, and a number of spaced guide wheels 22 are rotatably installed in the U-shaped seat 23, and adjacent guide wheels 22 are connected by a transmission mechanism. In actual use, the transmission mechanism is a chain drive, and a drive motor 24 is installed on one of the guide wheels 22, and the drive motor 24 is fixed to the U-shaped seat 23 through a bracket; a third linear drive module 25 is vertically installed on the side relatively far away from the two U-shaped seats 23, and the third linear drive module 25 is fixed on the outer wall of the U-shaped frame 21. After the pressure roller 12 presses against the pipeline to fix the pipeline, the third linear drive module 25 is fixed to the outer wall of the U-shaped frame 21. The module 25 will push the U-shaped seat 23 close to the pipe, so that the guide wheel 22 is pressed on the side of the pipe to further stabilize the pipe; and when the flaring tool 6 is pushed by the first linear drive module 2 to flare the pipe, the drive motor 24 will drive the guide wheel 22 to rotate synchronously, thereby providing the pipe with a force opposite to the operating direction of the first linear drive module 2, so as to cooperate with the rubber sleeves on the support roller 10 and the pressure roller 12 to stabilize the pipe during the flaring process. In actual use, an arc groove is provided on the side of the guide wheel 22 so that the guide wheel 22 can better fit the pipe, and the outer wall of the guide wheel 22 is also wrapped with a non-slip rubber sleeve to improve the effect of the guide wheel 22 on the pipe.
[0036] Furthermore, a third guide shaft 26 is provided parallel to the side of the third linear drive module 25. One end of the third guide shaft 26 is fixed on the U-shaped seat 23 and the other end slides through the U-shaped frame 21, providing guidance for the movement of the guide wheel 22, so that the guide wheel 22 can be stably placed on the pipe.
[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
