Embodiment

[0027] Traditional hot stamping dies often use drilling to manufacture cooling channels, but this processing method can only produce straight-line cooling channels, which often results in uneven cooling for large and complex parts. In view of the above problems, the present invention provides a method for manufacturing a hot stamping die with a conformal cooling channel, which includes a mold main part, a mold surface part, a sealing ring, bolts, etc., and the mold main part and the mold surface part They need to be machined separately, and each has an accompanying semicircular hole. After the two are assembled together and fixed with bolts, they can form a complete mold cooling channel. The invention cleverly solves the problem that parts with complex shapes are difficult to cool after hot forming, and the conformal cooling water channel processed by this method can make the cooling speed of each part of the part more uniform, and the forming quality can be significantly impro...

Abstract

The invention relates to an aluminum alloy hot punching die provided with shape follow-up cooling water channels and belongs to the technical field of hot punching dies. The aluminum alloy hot punching die comprises a die profile, a die base, a sealing ring and a bolt. The die profile is provided with a semi-circular hole and a boss. The die base is provided with a semi-circular hole and a groove. The die profile and the die base are combined and assembled and then fixed through the bolt, and form a plurality of complete shape follow-up water cooling channels. The aluminum alloy hot punching die skillfully solves the problem that parts with the complex shape are difficult to cool after hot forming is completed, by means of the shape follow-up water cooling channels machined through the method, the cooling speed of all portions of the parts can be more uniform, and the forming quality is improved remarkably. Practicality is high.

Description

technical field [0001] The invention relates to the technical field of hot stamping dies, in particular to an aluminum alloy hot stamping die with conformal cooling channels. Background technique [0002] Aluminum alloy hot stamping cold die quenching process can solve the problem of poor plasticity of aluminum alloy at room temperature and deformation after heat treatment. Aluminum alloy products formed by hot stamping have good formability, high shape accuracy, and can also reduce the weight of the vehicle body, and are now attracting more and more attention. [0003] The principle of aluminum alloy hot stamping and cold die quenching process is to heat the aluminum plate to 30-50°C above the solid solution temperature, and then quickly transfer it to the water-cooled mold after a period of heat preservation, and quickly close the mold under the drive of a high-speed press. The high plasticity of aluminum alloy at high temperature can form molded parts with complex shapes...
