Description
Technical Field
The utility model belongs to the technical field of dies, and relates to a one-die two-cavity stretch forming die.
Background
The stretch-forming die is a die commonly used for metal stamping and has a main function of stretch-forming a metal sheet to obtain a desired shape and size. However, in the use of the stretch forming die, there are problems and some drawbacks in that it is impossible to release the die in time after the completion of the stamping.
Firstly, the problem of incapability of timely demoulding is that the stretch forming die is subjected to larger pressure and friction force in the stamping process. As the sheet metal is stretched and compressed in the die, the gap between the die parts becomes very small. When the stamping of the metal plate is completed, the die cannot be separated from the metal plate immediately due to the influence of pressure and friction force, and a certain time is required to be passed for demolding. This results in a reduction in production efficiency and an extension of the manufacturing cycle time of the product.
Secondly, stretch-forming dies have some drawbacks. First, the service life of the mold is limited, and the mold gradually wears out with the increase of the number of uses. Particularly, in the stretch forming process, the die is subjected to larger stress and abrasion, and fatigue crack, deformation and other problems are easy to occur, so that the service life of the die and the forming quality are influenced. Second, because the stretch-forming die must have a relatively high hardness and strength, the selection of die materials and processing requirements are relatively high, which increases cost and complexity. In addition, the stretch-forming die needs to be precisely adjusted and maintained during the production process, which would otherwise lead to unstable quality of the finished product and risk of die damage, so that a one-die two-cavity stretch-forming die is needed to solve the above problems.
