Description

Technical Field

[0001] This utility model relates to the technical field of pipe bending processing, and in particular to a pipe end rounding support platform. Background Technology

[0002] During the production of bent pipes, a rounding process is required. Existing rounding equipment, such as the finishing machine pipe fitting external pressure rounding device disclosed in utility model patent CN211135031U and the pipe blank rounding machine disclosed in utility model patent CN217726710U, can all achieve the rounding of pipe fittings.

[0003] However, during use, it was found that the existing rounding equipment has a relatively simple structure, which is not convenient for rounding the ends of large-diameter and thick-walled bends, resulting in poor practicality. Therefore, there is an urgent need for a pipe end rounding support platform to improve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a pipe end rounding support platform that places the bent pipe on a rounding mechanism and provides power to the rounding mechanism through a hydraulic mechanism, so that the rounding mechanism can round the end of the bent pipe, thereby improving the practicality of the equipment.

[0005] This utility model provides a pipe fitting end rounding support platform, which includes a hydraulic mechanism and a rounding mechanism mounted on the hydraulic mechanism.

[0006] The hydraulic mechanism provides power to the rounding mechanism, which rounds the end of the bent pipe.

[0007] The bent pipe is placed on the rounding mechanism, and the rounding mechanism is powered by a hydraulic mechanism to round the end of the bent pipe, thereby improving the practicality of the equipment.

[0008] Preferably, the rounding mechanism includes a limiting mold and a rounding mold, both of which are mounted on a hydraulic mechanism. The bent pipe is placed on the limiting mold with the end of the limiting mold facing upwards. Then, the rounding mold is driven downwards by the hydraulic mechanism to extend into the end of the bent pipe and round the end of the bent pipe, thereby improving the practicality of the equipment.

[0009] Preferably, the hydraulic mechanism includes a base, a frame, a top plate, a hydraulic cylinder, and a lifting platform. The top plate is mounted on the base via the frame, the hydraulic cylinder is fixedly mounted on the top plate, the lifting platform is mounted at the bottom of the hydraulic cylinder, the rounding mold is mounted at the bottom of the lifting platform, and the limiting mold is mounted at the top of the base. The bent pipe is placed on the limiting mold with its end facing upwards. Then, the lifting platform moves downwards by extending the hydraulic cylinder, allowing the bottom of the rounding mold to extend into the end of the bent pipe. By pressing the end of the bent pipe with the rounding mold, the end of the bent pipe is rounded, thereby improving the practicality of the equipment.

[0010] Preferably, both ends of the lifting platform are provided with sliders, and the frame is provided with a sliding groove. The sliders are slidably installed in the sliding groove of the frame. During the lifting process, the lifting platform is guided by the slider sliding in the sliding groove of the frame to maintain the stability of the rounding mold.

[0011] Preferably, the base is provided with multiple sets of springs; after the lifting platform descends, the lifting platform compresses the multiple sets of springs, causing the multiple sets of springs to contract; when the lifting platform rises, the elasticity of the multiple sets of springs supports the lifting platform upwards, thereby reducing the burden on the hydraulic cylinder when it contracts.

[0012] Preferably, the rounding mold is an inverted frustum shape, and a fixing frame is provided on the top of the rounding mold; the rounding mold is fixed to the bottom of the lifting platform by the fixing frame, and the inverted frustum shape of the rounding mold supports the inside of the end of the bent pipe, thereby completing the rounding of the end of the bent pipe and improving the practicality of the equipment.

[0013] Preferably, the bottom of the limiting mold is provided with a raised edge; when the bent pipe is placed in the limiting mold, the raised edge limits the limiting mold and maintains the position of the bent pipe, thereby improving the stability of the bent pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the bent pipe is placed on the rounding mechanism, and the rounding mechanism is powered by the hydraulic mechanism, so that the rounding mechanism can round the end of the bent pipe, thereby improving the practicality of the equipment.

[0023] Example

[0024] like Figures 1 to 6 As shown, a pipe end rounding support platform includes a hydraulic mechanism; it also includes a rounding mechanism, which is mounted on the hydraulic mechanism.

[0025] The hydraulic mechanism provides power to the rounding mechanism, which rounds the end of the bent pipe.

[0026] The rounding mechanism includes a limiting mold 1 and a rounding mold 2, both of which are mounted on a hydraulic mechanism.

The hydraulic cylinder 6 is fixedly mounted on the top plate 5. The lifting platform 7 is mounted on the bottom of the hydraulic cylinder 6. The rounding mold 2 is mounted on the bottom of the lifting platform 7. The limiting mold 1 is mounted on the top of the base 3.

[0028] Both ends of the lifting platform 7 are provided with sliders 8, and the frame 4 is provided with a sliding groove, in which the sliders 8 are slidably installed.

[0029] Multiple sets of springs 9 are provided on the base 3;

[0030] The rounding mold 2 is an inverted frustum shape, and a fixing frame 10 is provided on the top of the rounding mold 2;

[0032] The limiting mold 1 is installed on the top of the base 3, and the fixing frame 10 is installed on the bottom of the lifting platform 7. The bent pipe is then placed on the limiting mold 1, so that the convex edge 11 supports the bottom of the bent pipe. Then, the hydraulic cylinder 6 extends, causing the lifting platform 7 to move downward, and the bottom of the rounding mold 2 is inserted into the end of the bent pipe. The rounding mold 2 squeezes the end of the bent pipe to achieve rounding. Then, the lifting platform 7 is supported upward by the elasticity of multiple sets of springs 9, so that the lifting platform 7 is reset, thereby improving the practicality of the equipment.
