Steel casting machining protection equipment capable of preventing pore defect

Abstract

The invention relates to the technical field of steel castings, and discloses steel casting machining protection equipment for preventing pore defects. According to the equipment, frames are fixedly mounted on the left side and the right side of a main body. According to the steel casting machining protection equipment capable of preventing the pore defects, when a pushing strip moves in the direction close to a rotating roller, the pushing strip can extrude a metal block to a certain degree, due to the fact that matched textures are arranged on a core rod and a spring component, when the spring component is compressed, the core rod movably connected with the interior of the spring component is pushed out upwards under the action of the reverse force of downward extrusion, the core rod generates certain pushing force on the round rotating disc at the top end, a round rotating disc rotates under the action of the pushing force of the core rod and the deflection force of the round rotating disc, and the round rotating disc makes contact with and is meshed with teeth on the frame, when the frame is touched by mistake, the metal blocks stop the frame, the center is prevented from being affected, deformation is prevented, and therefore the arrangement size precision and the internal quality are guaranteed.

Description

technical field [0001] The invention relates to the technical field of steel castings, in particular to a processing and protection equipment for steel castings for preventing pore defects. Background technique [0002] Steel castings refer to parts formed by pouring steel into a specific mold after smelting and cooling and solidifying. In layman's terms, steel castings refer to parts made of cast steel, which have similar properties to cast iron, but are stronger than cast iron. , the weight of steel castings can vary in a wide range, and the weight of the small ones can be investment castings with only tens of grams, while the weight of large steel castings can reach several tons, tens of tons or even hundreds of tons. It has high strength, high toughness and good weldability. [0003] However, in the traditional steel casting production equipment, some defects often appear in the steel after smelting. Since the steel casting is poured, the pouring time is often too short...

Problems solved by technology

[0003] However, in the traditional steel casting production equipment, some defects often appear in the steel after smelting. Since the steel casting is poured, the pouring time is often too short, and the filling is too fast, and the mold cannot Rapid vaporization, porosity defects are easy to appear after solidification. If it is used for a long time, the casing may break if it is serious. In addition, if the steel casting is accidentally touched or improperly operated during the casting process, it is easy to be distorted and deformed. Condition, dimensional accuracy and internal quality are difficult to guarantee. Once a large deformation occurs, there is no way to correct it in the later stage. Therefore, a casting protection equipment for preventing pore defects came into being.
