Aluminum cold forging refers to the forging and extrusion of the blank at room temperature. The utility model has the advantages that the surface roughness of the product is low, and the strength of the product is also improved due to the strengthening effect of deformation.

In today's forging parts, if the temperature is not well controlled or careless in the production process will cause a series of defects, which will greatly reduce the quality of forging parts.

Aluminum, a metal, is often seen in our daily life. The strength of pure aluminum is very low, only about 9 kg / mm2. Therefore, pure aluminum can not be used to manufacture structural parts bearing load, and alloy must be synthesized.

In case of crack, folding, forging injury, interlayer, scab, slag inclusion and other defects on the forging surface, the following provisions shall be followed.

Forging plant: the standardization of hydraulic equipment forgings is the development trend of forging technology.

Cold extrusion refers to putting the metal blank into the die cavity in the cold state, forcing the metal to extrude from the die cavity under the action of strong pressure and certain speed, so as to obtain the extrusion parts with required shape, size and certain mechanical properties. Obviously, the cold extrusion process depends on the die to control the metal flow and the large transfer of metal volume to form parts. It is an important part of precision plastic volume forming technology.

In today's forging parts, if the temperature is not well controlled or careless in the production process will cause a series of defects, which will greatly reduce the quality of forging parts. In order to eliminate this defect in forging parts, metal parts must be improved first to avoid the sensitive working pressure of steel parts in the whole forging process, which can increase the relative density of metal materials, It not only makes it less and less smooth and fine, but also makes it a high aluminum alloy. When carburizing in alloy steel, its body shape is broken.
