[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1The pipe end deformation and flanging device shown includes a base 1, a flanging mandrel assembly 6 movably disposed above the base 1, a pipe clamping mechanism located on one side of the flanging mandrel assembly 6 and fixed to the base 1, providing self-centering clamping and fixing of one end of the pipe. The flanging mandrel assembly 6 includes an initial flanging deformation mandrel, a middle deformation mandrel, and a final deformation mandrel. A pressure supply assembly is located on the side of the flanging mandrel assembly 6 away from the pipe clamping mechanism, driving the flanging mandrel assembly 6 to move horizontally and extruding one end of the pipe to deform and flange. In this embodiment, by combining the pipe clamping mechanism, the flanging mandrel assembly 6, and the power supply assembly... The components are integrated horizontally on the base 1, and the tube clamping mechanism not only clamps and fixes the tube, but also keeps the tube and the flanging mandrel assembly 6 at the same height. This ensures that the flanging mandrel assembly 6 is accurately aligned with one end of the tube, and that the force on the tube is accurate when the flanging mandrel assembly 6 applies horizontal pressure to one end of the tube. Furthermore, the extrusion deformation of one end of the tube by the flanging mandrel assembly 6 is performed in multiple steps. Compared with the one-time continuous forming method in the prior art, this method can make the force on the tube more stable and uniform, thereby improving the quality of the tube end deformation flanging process.

[0025] The pipe clamping mechanism includes a second fixing plate 7 and a pipe clamping assembly 8. The second fixing plate 7 is vertically fixed to one side of the top of the base 1. The pipe clamping assembly 8 is fixedly installed on the side of the second fixing plate 7 near the flanging core mold assembly 6, so that the pipe is self-centered and clamped by the pipe clamping assembly 8 to maintain the same core height as the flanging core mold assembly 6. The second fixing plate 7 is used for connection and support between the pipe clamping assembly 8 and the base 1, so that the pipe clamping assembly 8 can be stably assembled above the base 1. Combined with the self-centering clamping of one end of the pipe by the pipe clamping assembly 8 itself, it can meet the requirements of accurate and stable positioning of the pipe clamping position, making the installation and positioning of the pipe on the device more convenient, accurate and stable, thereby helping to improve the quality of the subsequent end deformation and flanging of the pipe.

[0026] The pressure supply assembly includes a first fixed plate 2 and a cylinder assembly 3. The first fixed plate 2 is vertically fixed to the top of the base 1 on the side away from the clamping mechanism. The cylinder assembly 3 is fixedly connected to the side of the first fixed plate 2 away from the movable plate 4. The piston rod on the cylinder assembly 3 passes through the first fixed plate 2 and is fixed to the flanging core mold assembly 6. The side of the flanging core mold assembly 6 near the first fixed plate 2 is detachably connected to the movable plate 4. The side of the movable plate 4 away from the flanging core mold assembly 6 is fixedly connected to one end of the piston rod on the cylinder assembly 3. An external hydraulic station supplies hydraulic oil to the cylinder assembly 3, driving the piston rod on the cylinder assembly 3 to translate the flanging core mold assembly 6, so that the flanging core mold assembly 6 can stably perform the extrusion deformation flanging work of the pipe end, and can ensure the pressure requirements of the flanging core mold assembly 6 for extruding and deforming the pipe end. At the same time, the movable plate 4 can meet the disassembly and assembly of the flanging core mold assembly 6, so that the initial deformation core mold, intermediate deformation core mold and final deformation core mold in the flanging core mold assembly 6 can be replaced and used in sequence according to the usage order.

[0027] Furthermore, guide rods 5 are fixedly connected to the top and bottom of the second fixed plate 7 and the first fixed plate 2, and bushings are fixedly installed on both the upper and lower sides of the movable plate 4. The movable plate 4 is slidably connected to the guide rods 5 through the bushings. The use of guide rods 5, together with the bushings mounted on the movable plate 4, enables the guide rods 5 to not only provide auxiliary support for the movable plate 4, but also to limit and guide the horizontal movement of the movable plate 4, making the movable plate 4 more stable during movement, thereby further improving the processing quality of the deformed and flanged end face of the extruded pipe by the movable plate 4.

[0028] In practice, one end of the pipe is inserted into the side of the pipe clamping assembly 8 for self-centering clamping. Then, the hydraulic station supplies pressurized oil to the cylinder assembly 3, causing the piston rod on the cylinder assembly 3 to drive the movable plate 4 and the flanging mandrel assembly 6 to move horizontally. The end of the flanging mandrel assembly 6 pushes against the end of the pipe, causing the pipe end to deform and flange. After maintaining the pressing state for a certain period of time, the flanging mandrel assembly 6 is withdrawn. Then, the intermediate deformation mandrel in the flanging mandrel assembly 6 is replaced and pressed again. Finally, the intermediate deformation mandrel is replaced and pressed again, thus completing the deformation and flanging requirements of the pipe end. The flanging mandrel assembly 6, composed of the initial deformation mandrel, intermediate deformation mandrel, and final deformation mandrel, can easily realize the flanging deformation of the pipe end, and makes the deformation processing of the pipe end more stable, reduces rebound, and improves the processing quality of pipe deformation and flanging. The process of flanging one end of the pipe is as follows: Figure 2 As shown.
