Technical Field

[0001] The utility model relates to the technical field of carbon-carbon insulation barrel forming and processing, in particular to a carbon-carbon insulation barrel forming die. Background Art

[0002] Carbon-carbon insulation barrel is a kind of insulation container used under high temperature and high pressure, which is made of carbon-carbon composite material. Its material has many excellent properties, such as high temperature oxidation resistance, thermal shock resistance, self-lubrication, etc., so it is widely used in chemical industry, metallurgy, energy and other fields. In the molding process of assembled carbon-carbon insulation barrel, molding molds are often needed to assist the assembly of carbon-carbon insulation barrel.

[0003] At present, the mold used for forming and assembling the carbon-carbon insulation barrel mainly consists of a bottom plate and an annular groove provided on the bottom plate. When in use, the mold of this structure supports the bottom of the single plate of the carbon-carbon insulation barrel with the help of the annular groove, and then realizes the assembly and forming of the carbon-carbon insulation barrel by gradually assembling the single plates of the carbon-carbon insulation barrel. Although the assembly and forming of the carbon-carbon insulation barrel can be realized under the action of the mold of the above structure, the assembled carbon-carbon insulation barrel plate and the mold are prone to sliding and skewing during the assembly process, resulting in the need to constantly straighten the assembled carbon-carbon insulation barrel plate during the assembly process. Since the straightening plate process needs to be repeated many times, the assembly process of the carbon-carbon insulation barrel is time-consuming and the assembly and forming efficiency is relatively low.

[0018] Furthermore, the sliding rod passes through the sliding hole, and the sliding rod is slidably connected to the sliding hole.

[0019] By adopting the above technical solution, the sliding hole can guide and limit the sliding of the sliding rod.

[0020] Furthermore, the slide rod passes through the spring, and one end of the spring is welded to the arc-shaped clamping plate, and the other end of the spring is welded to the receiving groove.

[0021] By adopting the above technical solution, the spring is in an extended state when not assembled, and during assembly, as the arc-shaped clamp moves into the storage groove, the clamp can reliably clamp the carbon-carbon insulation barrel assembly plate with the help of the resetting action of the spring.

Although the assembly and forming of the carbon-carbon insulation barrel can be realized under the action of the mold of the above structure, the assembled carbon-carbon insulation barrel plate and the mold are prone to sliding and skewing during the assembly process, resulting in the need to continuously move the assembled carbon-carbon insulation board during the assembly process. The barrel plate straightening process needs to be repeated many times, which makes the assembly process of the carbon-carbon insulation barrel take a long time and the assembly efficiency is relatively low. The utility model installs a clamping and limiting mechanism in an annular shape with equal intervals in the assembly cavity between the inner cylinder and the outer cylinder, so that when the mold is in use, the arc-shaped clamping plate in the clamping and limiting mechanism can be used to quickly clamp and limit the assembled carbon-carbon insulation barrel plate, thereby preventing the assembled carbon-carbon insulation barrel plate from sliding and skewing during the assembly process, eliminating the tedious operation of manual straightening, and making the assembly efficiency of the carbon-carbon insulation barrel higher.
