[0021] Clearly, the described embodiments are merely a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present utility model.
[0022] As shown in Figs. 1 to 4 A kind of clara pipe socket anti-shrinkage shaping device, including spigot 1, notch is provided on spigot 1, oblique plate 7 is fixedly connected on the inner wall of spigot 1 on one side of notch, further including telescopic rod 2 and tile 3 corresponding to notch, tile 3 one end is hinged with the inner wall of spigot 1, tile 3 other end is fixedly connected with push-up piece, push-up piece is abutted on the inclined surface of oblique plate 7, telescopic rod 2 two ends are respectively hinged with tile 3 and the inner wall of spigot 1.
[0023] In the manufacture of shaping device, first select the steel pipe with the same outer diameter as the socket inner diameter, then adopt the way of wire cutting to process the steel pipe into spigot 1 and tile 3, first weld hinge seat on spigot 1 and tile 3, then weld oblique plate 7 on spigot 1, then use air hammer to process spigot 1 to less than the inner diameter of socket, then use the way of heat treatment to process spigot 1 and tile 3 to be rich in elasticity, finally assemble tile 3 to spigot 1, and install push-up piece.
[0024] When implementing: after clara pipe is processed from extruder by socket, spigot 1 is inserted into socket, then tile 3 is driven by telescopic rod 2 to block the notch of spigot 1, so that spigot 1 and tile 3 constitute a complete circular pipe, spigot 1 is shaped by the circular pipe, and small boss is not generated.
[0025] Further, the push-up piece includes ear plate 4 fixedly connected on tile 3, and the ear plate 4 has arc-shaped head end. Arc-shaped head end can avoid scratching oblique plate 7.
[0026] Further, shaft rod is fixedly connected between two ear plates 4, and top pipe 5 is sleeved on the shaft rod, and the outer wall surface of top pipe 5 is abutted on oblique plate 7. When tile 3 is driven to expand spigot 1, top pipe 5 rolls on oblique plate 7, so that dry grinding between ear plate 4 and oblique plate 7 is changed into rolling friction, which can further avoid scratching oblique plate 7, and driving tile 3 is more easy and labor-saving.
[0027] Further, the telescopic rod 2 includes screw pipe 21, the screw pipe 21 is provided with threads at two ends, and the thread directions of the two ends are opposite, and screw rod 23 is assembled at two ends of screw pipe 21 respectively, and one end of the two screw rods 23 is hinged with tile 3 and the inner wall of spigot 1 respectively. The telescopic rod 2 with such structure is simple in structure, and is convenient for processing and manufacturing.
[0028] Further, the plurality of torsion bars 22 are fixedly connected to the screw pipe 21. The screw pipe 21 can be manually rotated through the torsion bars 22.
[0029] Further, the upper end of the inclined plate 7 is fixedly connected to the inner wall of the insertion pipe 1 through the support plate 6. The support plate 6 supports the inclined plate 7, avoiding deformation of the inclined plate 7 and improving the service life of the device.
[0030] Further, the tile 3 is provided with a chamfer at the edge of one end facing the inclined plate 7, and the edge of the insertion pipe 1 on one side of the gap is provided with a bevel matched with the chamfer of the tile 3. The bevel can improve the sealing effect between the tile 3 and the insertion pipe 1 and help eliminate the gap between the tile 3 and the insertion pipe 1.
[0031] Further, the insertion pipe 1 and the tile 3 form a circular pipe structure, and one end of the circular pipe structure is provided with a chamfer. The chamfer has a guiding effect, which can facilitate the insertion of the device into the socket.
