摘要： The present invention intends to provide a shower of a large diameter MOCVD reactor, and the difficulty for manufacturing the shower does not obviously increase when its size increases. The shower of a large diameter MOCVD reactor of the present invention comprises III group chamber, V group chamber and a cooling water chamber, and it is characterized in that, III group chamber, V group chamber and cooling water chamber are all separated as N chambers, wherein N is a natural number greater than or equal to 2 and each chamber is an individual unity.

摘要： A stamping apparatus that includes an upper die, a blank-holding binder, and fixed lower die. The fixed lower die features a drawing punch and the upper die features a corresponding cavity. The fixed lower die includes a stake bead and a corresponding depression is present on the upper die. The blank-holding binder includes a draw bead and a corresponding depression is present on the upper die. In the stamping process, the draw bead engages a blank in a first stage, causing the blank to begin to stretch into the shape of the drawing punch with a greater tightened partially finished panel shape. In a second stage, the draw bead disengages the blank as the blank is drawn towards the drawing punch. In a final stage, the stake bead engages the blank to tighten the blank around the drawing punch into a final shape.

摘要： The present disclosure provides stamping apparatus for stamping a blank. The stamping apparatus includes a first die and a blank-holding ram. The first die includes a forming cavity and a depression positioned outboard of the forming cavity. The depression is defined by a first corner proximate the forming cavity and a second corner distal the forming cavity in the outboard direction from the first corner and the forming cavity. The blank-holding ram includes a bead configured to engage a portion of the blank into the depression when the blank is positioned between the first die and the blank-holding ram. The bead includes a third corner proximate the forming cavity and a fourth corner surface distal the forming cavity in the outboard direction from the third corner. The first corner of the depression includes a radii of curvature greater than a radii of curvature of the second corner of the depression and the radii of curvature of the third and fourth corners of the bead.
