Embodiment 1
[0040] figure 1 Among them, the present invention discloses a manufacturing method of an MC nylon pipeline flange reinforcing device, the reinforcing device is a reinforcing member arranged in a flange, and the manufacturing method comprises the following steps:
[0041] Step I. Select steel plates of different thicknesses and process the inner and outer diameters of the steel plates according to the different calibers of the flanges to form the reinforcement 1;
[0042] Step II. Drill holes on the reinforcement 1, including the nylon penetration hole 1 during the molding process and the reserved hole 4 for installation after molding;
[0043] Step III. Fold the fixing part 3 matching the notch of the casting mold with a steel wire, and then fix the fixing part 3 on the reinforcement part 1 . In this embodiment, four fixing components 3 are provided, which are evenly fixed on the edge of the reinforcing member 1 .
[0044] Specifically, a Φ10mm hole head is selected to unif...
Embodiment 2
[0049] The steps of the manufacturing method of the MC nylon pipe flange strengthening device in this embodiment are the same as those in Embodiment 1, except that when the reserved hole 4 is drilled, it is 6mm larger than the diameter of the standard bolt hole, which can ensure that there is a nylon layer around the hole after drilling. If it is thicker, the reinforcement 1 is not exposed, and the effect of the flange wrapping the reinforcement 1 is better, and the nylon layer plays a protective role and prevents corrosion.
[0050] The height difference between the free end 31 and the fixed end 32 of the fixing member 1 is 10 mm. The free end 31 is higher than the fixed end 32 by a certain height, so that a layer of MC nylon layer can be cast into the disk surface of the reinforcement 1 near the pipe side, and the reinforcement 1 is completely wrapped in the flange. The curved ruler-shaped hook is adopted, and the reinforcing member 1 is conveniently fixed with the casting mol...
Embodiment 3
[0053] The present invention also discloses a manufacturing method of the MC nylon pipeline flange integrally formed with the above-mentioned strengthening device, which includes the following steps, such as figure 2 ,
[0054] Step 1. At the inner diameter port of the mold shaft cover of the casting mold, according to the shape and length of the fixing part on the reinforcing member, corresponding gaps for fixing the fixing parts are made; in this embodiment, the gaps on the end of the casting mold are set to 4, Evenly distributed at the inner diameter port of the mold shaft cover to ensure that it is used in conjunction with the fixing part 3 on the reinforcement part 1.
[0055] Step 2. Clean the casting mold and apply release oil evenly;
[0056] Step 3. Align the fixing parts on the reinforcement with the gaps of the mold shaft covers placed at both ends of the casting mold;
[0057] Step 4. Preheat the casting mold and inject MC nylon to make the flange;
[0058] Ste...
