When an external force acts on the lower supporting plate 6 downwards, the lower supporting plate 6 drives the lower profiling block 4 to move downwards and compress the lower return spring 7; after the external force is removed, the lower support plate 6 drives the lower profiling block 4 to move upwards under the action of the lower return spring 7, so that the reset is completed. Meanwhile, under the limit sliding fit between the first through hole 61 and the lower clamping block 52, the lower support plate 6 and the lower profile modeling block 4 are prevented from swinging along the horizontal direction in the moving process, so that the positioning accuracy between the lower profile modeling block 4 and the upper profile modeling block 3 is improved.

When the top plate 2 moves downwards, the upper supporting plate 9 and the upper profiling block 3 are driven to synchronously move downwards, until the upper profiling block 3 is contacted with the lower profiling block 4, the upper supporting and the upper profiling block 3 stop moving, and the top plate 2 can still move downwards continuously (an upper return spring 10 is compressed), so that the positioning groove 300 between the upper profiling block 3 and the lower profiling block 4 is ensured to clamp the fixed column pipe body 100; meanwhile, when the upper contour block 3 is pressed downwards on the lower contour block 4, the lower return spring 7 is compressed, so that the lower support plate 6, the lower contour block 4, the pipe body 100, the upper contour block 3 and the upper support plate 9 synchronously move downwards, and the pipe body 100 and the pipe joint 200 are prevented from being bent in the clamping process; moreover, the overall force between the upper support plate 9 (upper profile block 3) and the lower support plate 6 (lower profile block 4) is more uniform by the action of the upper return spring 10 and the lower return spring 7.

Referring to fig. 2, in some embodiments of the present application, the one-station crimping pre-positioning tool further comprises a profiling positioning element 20, the profiling positioning element 20 being used to position the pipe joint 200 onto the lower support plate 6. Since the pipe body 100 is placed in the positioning groove 300 between the upper contour block 3 and the lower contour block 4 and can float up and down along with the lower support plate 6, the pipe joint 200 is positioned on the lower support plate 6 by positioning the pipe joint 200 through the contour positioning member 20, which can improve the assembly accuracy between the pipe joint 200 and the pipe body 100 and can ensure that the pipe joint 200 can float up and down along with the pipe body 100. The specific structure of the profiling positioning member 20 is not limited by the present application and only two reference structures are provided below:

the first embodiment is as follows: referring to fig. 3 and fig. 5 to 6, the profiling positioning element 20 includes a positioning block 204 and a locking rod 205, and a flat-long-structured limiting hole 2041 is formed through the positioning block 204; one end of the locking rod 205 is provided with a limiting part 2051, and the other end of the locking rod 205 is provided with a locking part 2052 matched with the limiting hole 2041; when the locking portion 2052 passes through the limiting hole 2041 and is rotated to dislocate the locking portion 2052 from the limiting hole 2041, the positioning block 204 and the limiting portion 2051 can clamp the pipe joint 200 therebetween.

Example two: referring to fig. 2-4 and 9-12, the profiling positioning member 20 includes a supporting block 201, a pressing block 202, and a buffer spring 203; the supporting block 201 is arranged on the lower supporting plate 6, and the upper end of the supporting block 201 is provided with a contour groove 2011 for positioning the pipe joint 200; the upper end of the pressing block 202 is connected with the upper support plate 9 through a buffer spring 203, and when the upper support plate 9 moves downwards, the lower end of the pressing block 202 can press the pipe joint 200 in the profile groove 2011. Meanwhile, under the action of the buffer spring 203, the lower end of the compression block 202 can be prevented from being unable to contact the pipe joint 200 or deforming the pipe joint 200 due to being pressed too tightly.

Referring to fig. 8 and 11, in some embodiments of the present application, the one-stop crimping pre-positioning tool further includes a guide pillar 30 and a guide sleeve 40, a lower end of the guide pillar 30 is mounted on the bottom plate 1, and a sliding hole 62 for connecting the guide pillar 30 in an up-and-down sliding manner is formed through the lower support plate 6; the upper end of the guide sleeve 40 is arranged on the upper supporting plate 9, and the guide sleeve 40 is connected to the upper end of the guide post 30 in a vertical sliding mode.

Under the action of the limiting rod 50 and the cushion block 60, the pipe body 100 and the pipe joint 200 are prevented from being excessively deformed due to the fact that the upper supporting plate 9 and the lower supporting plate 6 are pressed too tightly; meanwhile, the die closing force can be quickly adjusted by replacing the cushion blocks 60 with different thicknesses, the die adjusting time is saved, and the qualification rate of the working procedure is improved. In addition, when the limiting block 70 is simultaneously contacted with the upper supporting plate 9 and the top plate 2, the top plate 2 drives the upper supporting plate 9 to move downwards simultaneously, so that transitional compression between the upper supporting plate 9 and the top plate 2 is avoided, otherwise, the acting forces of the upper return spring 10 and the lower return spring 7 are too large, and the tooling and the product are easily damaged.

Referring to fig. 13 to 14, in some embodiments of the present application, the clamping area 54 has a regular polygon structure, so that the portion of the pipe joint 200 connected to the pipe body 100 is pressed into a regular polygon structure, the appearance is attractive, and relative rotation between the pipe joint 200 and the pipe body 100 can be avoided, so as to improve the accuracy and stability of the assembly positioning between the pipe joint 200 and the pipe body 100.
