Flange forge piece die resistant to high temperature

Abstract

The invention discloses a flange forge piece die resistant to high temperature. The flange forge piece die comprises an upper die body and a lower die body, the lower die body is located below the upper die body, locating rods are welded to all the four corners of the upper portion of the lower die body, and a homocentrically-square-shaped pipe is arranged among the locating rods, and arranged inside the lower die body; a water inlet pipe is fixedly connected to one side of the homocentrically-square-shaped pipe, a water outlet pipe is fixedly connected to the other side of the homocentrically-square-shaped pipe, a heat resistance layer is movably connected to the inner side of the homocentrically-square-shaped pipe, a concave plate is embedded into the inner side of the heat resistance layer, handles are welded to both sides above the concave plate, and a convex plate is fixedly installed below the upper die body. According to the flange forge piece die resistant to high temperature,through the combination of the heat resistance layer and the concave plate, it is effectively avoided that the lower die body is broken due to high temperature; through the combination of the homocentrically-square-shaped pipe, the water inlet pipe and the water outlet pipe, the speed of cooling products can be increased. and the cooling effect is great; through the combination of the upper die body and a cooling plate, the cooling speed inside the die is increased, and the production efficiency is greatly improved.

Description

【Technical field】 [0001] The invention relates to a die, in particular to a high temperature resistant flange forging die. 【Background technique】 [0002] Flanges are parts that connect pipes and pipes and valves to each other. They are connected to pipe ends and are also useful for flanges on equipment inlets and outlets. They are used for the connection between two devices and are parts that connect pipes to pipes. An accessory product of pipelines, the main materials of forged flanges are carbon steel, alloy steel, stainless steel, the main standards are national standard, electric standard, American standard, German standard, Japanese standard, etc., the main anti-corrosion treatment is oiled and Galvanized and forged flanges have better pressure and temperature resistance, and are generally suitable for high-pressure and high-temperature working environments.

AI Technical Summary

Problems solved by technology

[0003] During the forging process of existing flange forgings, cracks appear in the mold due to high temperature, which greatly affects the quality of the product, and the product cools too slowly in the mold, which reduces the production efficiency. The upper and lower molds are aligned, so that the product is deformed and the phenomenon of mold jumping occurs. After the product is formed, the high temperature of the mold will cause burns when the mold is reversed.
