[0002] Steel pipe flaring is a common metal processing technology, mainly used to increase the port diameter of steel pipes to facilitate connection or adaptation with other components. This technology can be achieved through various methods, including mechanical diameter expansion, hydraulic diameter expansion, cold rolling flaring, etc. A flaring machine is required for steel pipe flaring.

[0003] After retrieval, the utility model with the publication number of CN211588225U and the name of a flaring machine for manufacturing plastic-coated steel pipes includes a base. Through research and analysis, it is found that although it has the advantages of simple installation and disassembly of tiles and convenient replacement of punch heads, to a certain extent, it also has the following disadvantages.

[0004] For example, when in use, only the punch is inserted into the steel pipe for flaring, without the function of rotating flaring. Therefore, the punch cannot flare the steel pipe well, which easily causes uneven force application, reduces the flaring accuracy, and can only clamp the steel pipe at a fixed position, without the function of clamping and limiting according to the length of the steel pipe. Therefore, the clamping effect on the steel pipe is affected, resulting in unstable clamping of the steel pipe and affecting the flaring of the steel pipe. To solve the above technical problems, we designed a hydraulic steel pipe flaring machine. Content of the Utility Model

The connection part between the flaring cone 401 and the connecting plate 405 is movably connected by a bearing;

[0022] Please refer to Figure 1 , Figure 2 and Figure 4 , A support rod 206 is penetrated and arranged on the surface of the moving plate 205. The left and right ends of the support rod 206 are both fixedly connected to the surface of the fixing plate 9 by bolts. The top end of the support frame 201 penetrates to the top of the horizontal plate 1. On the top of the support frame 201, a first hydraulic cylinder 202 is connected by bolts.

[0023] Please refer to Figure 1 , Figure 2 and Figure 4 , On the front and rear sides of the upper clamping plate 207, T-shaped limit blocks 203 are welded. By setting the T-shaped limit blocks 203, the upper clamping plate 207 can be limited, thus maintaining the stability when the upper clamping plate 207 moves downward. The end of the T-shaped limit block 203 away from the clamping plate 207 penetrates to the outside of the support frame 201. Limit holes are opened on the front and rear sides of the support frame 201. A moving hole is opened on the right side of the top of the horizontal plate 1;
