[0022] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.

[0023] like Figures 1 to 6 As shown:

[0024] Embodiment 1: This embodiment provides a flange hole expansion device, including an installation component 1, the installation component 1 includes a mounting seat 101, a driving roller 102, a driving motor 103 and a supporting roller 104, the driving roller 102 is rotatably connected to the side of the top of the mounting seat 101, and the driving motor 103 is fixedly installed on the top of the mounting seat 101, the rotating shaft of the driving roller 102 is transmission-connected to the driving roller 102, and the supporting roller 104 is rotatably connected to the side of the bottom of the mounting seat 101; it also includes an extrusion component 2, the extrusion component 2 includes a movable frame 201, an extrusion roller 202, a pressure seat 203 and a lifting motor 206, the movable frame 201 is plugged into the interior of the mounting seat 101, and the extrusion roller 202 is rotatably connected to the side of the movable frame 201, the pressure seat 203 is rotatably connected to the interior of the movable frame 201, and the lifting motor 206 is fixedly installed on the side of the movable frame 201.

[0025] In the embodiment of the present disclosure, a fixing screw 1011 is provided on the side of the mounting seat 101, and the rod body of the fixing screw 1011 passes through the interior of the pressure seat 203. The extrusion assembly 2 also includes a lifting seat 204 and a spring swivel 205. The spring swivel 205 is rotatably connected to the bottom of the lifting seat 204, and the fixing screw 1011 is screwed into the interior of the lifting seat 204 through the rod body thread. In use, the extrusion assembly 2 and the mounting assembly 1 can realize the expansion processing operation of the flange workpiece. The flange workpiece is placed between the driving roller 102 and the extrusion roller 202, and then the power of the driving motor 103 and the lifting motor 206 is turned on to perform the processing operation. A linkage gear 2031 is provided at the bottom of the pressure seat 203, and a transmission gear 2061 is provided at the top of the rotating shaft of the lifting motor 206. The gear teeth of the transmission gear 2061 and the linkage gear 2031 are engaged for transmission. The lifting motor 20 When rotating, the transmission gear 2061 can drive the pressure seat 203 to rotate through the linkage gear 2031. Since the synchronous gear 2041 is inserted into the synchronous tooth groove 2032 under the action of the hole expansion tension spring 2051, the pressure seat 203 can drive the lifting seat 204 to rotate synchronously when rotating. The lifting seat 204 can move up and down through the rod thread of the fixed screw 1011 when rotating. Therefore, when the lifting seat 204 moves upward, it can drive the pressure seat 203 and the moving frame 201 to move upward synchronously through the hole expansion tension spring 2051, and then the extrusion roller 202 can cooperate with the driving roller 102 to perform the ring expansion operation on the flange workpiece, and the driving motor 103 can drive the driving roller 102 to rotate when rotating, and the driving roller 102 can drive the flange workpiece to rotate on the side of the mounting assembly 1, so that the ring expansion operation can be evenly performed on the flange workpiece, which is convenient for processing.

[0026] In the disclosed embodiment, a hole-expanding tension spring 2051 is provided at the bottom of the spring swivel 205, and the two ends of the hole-expanding tension spring 2051 are respectively fixedly connected to the bottom of the spring swivel 205 and the top of the pressure seat 203, a synchronous gear 2041 is provided at the bottom of the lifting seat 204, and a synchronous tooth groove 2032 is provided at the top of the pressure seat 203, and the synchronous gear 2041 is plugged into the interior of the synchronous tooth groove 2032. During use, in the normal processing state, the hole-expanding tension spring 2051 can always maintain the plug-in relationship between the synchronous gear 2041 and the synchronous tooth groove 2032, thereby ensuring that the extrusion component 2 can move upward smoothly to apply the rolling ring pressure. When the rolling ring pressure is too large, the extrusion component 2 can automatically trigger the protection function. The rolling ring pressure is the deformation resistance of the flange workpiece during the ring rolling processing. When the pressure is too large, the deformation speed of the flange workpiece is less than the upward movement distance of the pressure seat 203, that is, the displacement of the movable frame 201 is less than the displacement of the pressure seat 203, so that the synchronous gear 2041 may be disengaged from the interior of the synchronous tooth groove 2032 and the reaming spring 2051 is lengthened, and the plug-in relationship between the synchronous gear 2041 and the synchronous tooth groove 2032 is released, so that the pressure seat 203 will not rotate and can maintain the current use position, and under the action of the stretched reaming spring 2051, the movable frame 201 can always maintain a certain pressure to continue to crush the flange workpiece to deform it, until the flange workpiece reaches the standard deformation amount, the reaming spring 2051 will again insert the synchronous gear 2041 into the synchronous tooth groove 2032 to realize subsequent processing operations, and the use is stable.

[0027] The specific usage and function of this embodiment are as follows:

[0028] In the present invention, the extrusion assembly 2 and the installation assembly 1 can realize the hole expansion processing operation of the flange workpiece. The flange workpiece is placed between the driving roller 102 and the extrusion roller 202, and then the processing operation can be carried out after the power of the driving motor 103 and the lifting motor 206 is turned on. When the lifting motor 206 rotates, the transmission gear 2061 can drive the pressure seat 203 to rotate through the linkage gear 2031. Because the synchronous gear 2041 is inserted into the interior of the synchronous tooth groove 2032 under the action of the hole expansion tension spring 2051, the pressure seat 203 can drive the lifting motor 2061 to rotate when the lifting motor 206 rotates. The lowering seat 204 rotates synchronously, and the lifting seat 204 can move up and down through the rod thread of the fixed screw 1011 when rotating, so that the lifting seat 204 can drive the pressure seat 203 and the moving frame 201 to move upward synchronously through the hole expansion tension spring 2051 when moving upward, and then the extrusion roller 202 can cooperate with the driving roller 102 to perform the ring expansion operation on the flange workpiece, and the driving motor 103 can drive the driving roller 102 to rotate when rotating, and the driving roller 102 can drive the flange workpiece to rotate on the side of the mounting assembly 1, so that the flange workpiece can be rolled evenly. During the ring expansion operation, in the normal processing state, the expansion tension spring 2051 can always maintain the plug-in relationship between the synchronous gear 2041 and the synchronous tooth groove 2032, so as to ensure that the extrusion assembly 2 can move upward smoothly to apply the ring rolling pressure. When the ring rolling pressure is too large, the extrusion assembly 2 can automatically trigger the protection function. The ring rolling pressure is the deformation resistance of the flange workpiece during the ring rolling process. When the ring rolling pressure is too large, the deformation speed of the flange workpiece is less than the upward movement distance of the pressure seat 203, that is, the displacement of the moving frame 201 is less than the displacement of the pressure seat 203, so that the synchronous gear 2041 can be moved upward smoothly. 1 or escapes from the interior of the synchronous tooth groove 2032 and stretches the expansion spring 2051, the plug-in relationship between the synchronous gear 2041 and the synchronous tooth groove 2032 is released, so that the pressure seat 203 will not rotate and can maintain the current use position, and under the action of the stretched expansion spring 2051, the movable frame 201 can always maintain a certain pressure to continue to roll the flange workpiece to deform it, until the flange workpiece reaches the standard value of the deformation amount, the expansion spring 2051 will again insert the synchronous gear 2041 into the synchronous tooth groove 2032 to achieve subsequent processing operations.

[0029] In another embodiment, a track groove is provided inside the mounting base 101 to limit the moving trajectory of the movable frame 201. This design can limit the moving path of the movable frame 201 when the flange workpiece is expanded, thereby avoiding the movable frame 201 from tilting or twisting during movement, which may cause the device to become stuck and fail, and ensures stable use.
