Deep drawing process

Deep drawing is the use of drawing die flat plate blank pressed into a variety of openings in the hollow workpiece, or made of open hollow pieces into other shapes of hollow pieces of a stamping process, drawing is also called drawing. The deformation process is as follows: With the punch down, the outer diameter of the blank left on the die face is shrinking, the circular blank is gradually pulled into the convex, the gap between the concave mold to form a straight wall, and in the punch below Of the material is the bottom of the drawing parts, when the sheet into all the convex, concave and concave between the gap is the end of the process, the plane blank becomes a certain diameter and height of the cup. Compared with the punching die, drawing the convex part of the working part of the die should not have a sharp edge, and has a certain rounded corners, convex and concave between the single side gap slightly larger than the material thickness.

With the drawing process can be made cylindrical, ladder, spherical, conical, parabolic and other rotating parts.

Metal Nuts (Stainless Steel Nuts,Brass nuts,Metal Flat Nuts,Stainless Steel Square Nut,Flange Nuts,hex nuts,Cap nut etc).

metal nuts

The nut is a nut, a part that is screwed with a bolt or screw for fastening, and a component that must be used for all manufacturing machines. According to the different materials, divided into carbon steel, stainless steel, non-ferrous metals (such as copper) and other major types. According to the main attributes of the national standard (GB), German standard (DIN), international standard (ISO), Japanese standard (JIS), American Standard (ASTM / ANSI) and other standards. The nut performance grade label consists of two parts, representing the nominal tensile strength and yield ratio of the nut material, respectively. Nuts are parts that are tightly connected to the machine and can be connected together by the inner thread, the same size nut and bolt
