Problems solved by technology

[0003] However, at present, most of the hot stamping production lines in my country have introduced foreign equipment, and imported lubricants are often used in the process, resulting in high production costs.
[0004] In addition, the parts and components processed by the conventional hot stamping forming process are prone to surface problems such as cracking and wrinkling.

Abstract

The invention relates to a lubricant for hot stamping and a high-strength aluminum alloy hot stamping and quenching integrated process. The high-strength aluminum alloy hot stamping and quenching integrated process includes steps: acquiring a plate, subjecting to solution treatment, performing heat transferring into a water cooling mould, and carrying out hot stamping forming and pressure-maintaining quenching integrated treatment in the water cooling mould, to be specific, performing aging treatment by adopting the hot stamping lubricant comprising lard and talcum powder in a specific ratio to obtain a high-strength aluminum alloy product. A product processed according to the high-strength aluminum alloy hot stamping and quenching integrated process avoids problems of pull cracks, creasing and the like, cost of the lubricant can be effectively reduced, and accordingly production cost is saved.

Description

technical field [0001] The invention relates to the technical field of stamping, in particular to a hot stamping lubricant and a high-strength aluminum alloy hot stamping and quenching integrated process. Background technique [0002] Compared with the traditional stamping process, the hot forming process technology of alloy aluminum sheet can produce parts with lighter weight, higher strength, more complex shape and higher dimensional stability in one step. The auto parts produced by the hot forming process of alloy aluminum plate can effectively reduce the weight of the body, reduce fuel consumption, and be more environmentally friendly, which has very obvious advantages. [0003] However, at present, most of the hot stamping production lines in my country have imported foreign equipment, and imported lubricants are often used in the process, resulting in high production costs. [0004] In addition, the parts and components processed by the conventional hot stamping formi...
