Example Embodiment
[0041] Example 1, see attached figure 1 , The auxiliary shaping device for plastic pipe production includes a frame 1. In this embodiment, the frame 1 is an integral piece and is welded by steel pipes. The frame 1 is fixed on a rotating seat 12, and a plurality of mounting holes 12a are evenly distributed on the rotating seat 12. At the same time, the rotating seat 12 is fixed on the bottom plate 15, and is connected to the cooling water tank and the vacuum sizing box through the bottom plate 15, from figure 1 It can be seen that there are four mounting holes 12a in this embodiment, which are long slots for easy adjustment. The left roller 4 and the right roller are rotatably installed on the frame 1 through the left rotating shaft 2 and the right rotating shaft 3. 5. The left rotating shaft 2 and the left roller 4, the right rotating shaft 3 and the right roller 5 can be integrally formed or assembled separately. This embodiment adopts the form of separate assembly. The left ro...
Example Embodiment
[0042] Example 2, see attached figure 2 , 3 The disadvantage of embodiment 1 is that after the left roller 4 and right roller 5 are installed, it is not easy to adjust. An auxiliary shaping device can only fit a plastic pipe of one specification. In order to overcome this shortcoming, install it on the frame 1. There are upper linear guide 6, lower linear guide 7, upper linear guide 6, lower linear guide 7 can be purchased standard parts, of course, the price is more expensive, you can also use the structure in this embodiment, in this embodiment two The round tube is used as the guide rail of the upper linear guide 6 and the lower linear guide 7, and four linear bearings are used as the slider of the upper linear guide 6 and the lower linear guide 7. Its structure is very simple, the price is very cheap, and the performance can meet the needs. The sliders of the upper linear guide 6 and the lower linear guide 7 are fixed with a left moving part 8, a right moving part 9, and th...
Example Embodiment
[0043] Example 3, see attached Figure 4 Although Embodiment 2 can be applied to plastic pipes with different diameters, it is necessary to rotate the left and right handwheels to adjust. The adjustment speed is slow, cumbersome, long adjustment time, and not necessarily synchronized. In order to solve this problem, this implementation The propelling device 10 in this mode includes a screw 10g, the screw 10g has a left external thread 10g1, a right external thread 10g2, the left external thread 10g1, a right external thread 10g2, and the left moving part 8 , The right moving part 9 is screwed, the left moving part 8 and the right moving part 9 can be provided with internal screw holes or mounting screw sleeves to cooperate with the left external thread 10g1 and the right external thread 10g2. The end of the screw 10g is fixed with a hand wheel 10h , The screw 10g is driven to rotate by the handwheel 10h. Because the left external thread 10g1 and the right external thread 10g2 r...
