Appropriate stress can enhance the material's ability to withstand external loads, but continuous stress loading can cause metal fatigue, destroy the metal's material strength, and cause it to crack or break. During the cold extrusion process of aluminum, the presence of excessive stress can cause cracks and fractures in the aluminum during the cold rolling process, affecting the cold extrusion effect of the aluminum. In order to achieve better cold extrusion operations on aluminum, an aluminum cold extrusion device is needed.

A stress relief oil spray device is arranged on the left side of the cold rolling roller, and a multifunctional box is arranged on the right side of the cold rolling roller. A through slot for the aluminum sheet to pass through is opened on the box shell of the multifunctional box. The interior of the multifunctional box is divided into a spray chamber, a drying chamber and a finishing chamber from left to right. A water spray device is arranged in the spray chamber, a drying device is arranged in the drying chamber, and a grinding device is arranged in the finishing chamber. The utility model has a simple structure. It is reasonable to remove stress before cold rolling to improve the quality of aluminum strips. A stress relief oil spraying device is set up to spray cold rolling oil on the aluminum strips while removing the internal stress of the aluminum strips, thereby improving production efficiency.
