Background
The blank is raw material that has not yet been processed and may also refer to the portion of the finished product that has not yet been completed. For blanks of more complex shape, casting methods are generally used. For a frame-shaped sheet aluminum alloy fitting with high requirement on product flatness, the thickness of the product wall is as thin as 1mm at the thinnest part during machining, so how to clamp the frame-shaped sheet aluminum alloy fitting becomes the most important factor for solving the machining flatness.
In the existing production, the products are processed by adopting die casting, and the periphery of a blank piece which is processed by die casting is provided with a process piece for clamping and positioning.
