The material is a roll of raw materials that can be used for multiple stamping.

Sheet material is a plate-shaped raw material that can be used for multiple stamping.

Strips are strip-shaped raw materials that can be used for multiple stamping.

The drawing marks are the friction marks of the material surface and the working surface of the die during the forming process of the punched part.

The draw ratio is the reciprocal of the draw coefficient. Refer to "Drawing factor".

The drawing coefficient is the ratio of the diameter of the cylindrical drawing element in this process to the diameter of the drawing element in the previous process. For a deep drawing, the drawing coefficient is the ratio of the diameter of the drawing piece to the unfolded diameter.

The lug is an ear-shaped protrusion at the edge of the upper mouth of the deep-drawn part.

Feeding is to send raw materials into the mold for stamping.

The feeding device is a device that feeds raw materials into the mold. Common feeding devices are roller type, clamping type, hook type, etc., refer to related terms.

The hopper is a bucket-shaped container with a mechanism for automatically orienting the forming punch.

The bending radius is the inner radius of the punched part.

The unfolded drawing is a graphic of a flat process part corresponding to the forming punch.

The unfolded size is the size of the flat process part corresponding to the size of the forming punch.

Arching is the name of the phenomenon of uneven arching on the surface of punching parts.

Wrinkling is the name of the phenomenon of wavy wrinkles on the flange of the deep-drawn part.

The chute is a groove-shaped channel that allows punches to enter or leave the die in sequence.

The hook feeder is a device that uses the reciprocating hook to extend into the hole to drive the raw material into the die.

Organizing is to stack the punched parts (mostly punched parts).

The sorting device is a device for stacking the punched pieces.

Layout is the process of designing the die to complete the layout drawing. Sometimes the layout drawing is also referred to simply as the layout.

The layout drawing is a layout diagram describing the stepwise formation process of the punching piece on the strip (ribbon, roll) material, the position finally occupied and the relationship between the adjacent punching pieces.

Sticky die is the name of the phenomenon that the working surface of the die is bonded to the material of the punched part.

Chipping is the name of the phenomenon that small pieces of the edge of the punch or die are peeling off.

The small bending radius refers to a small bending radius that can be successfully bent.

Overlap is a small distance between the contours of adjacent punched parts in the layout drawing, or a small distance between the punched part contour and the edge of the strip.

The collapse angle has two meanings. One refers to the phenomenon that the outer edge of the blanking part is near the concave die surface or the inner edge is close to the convex die surface, and the other refers to the height hg of the part of the blanking part that is collapsed.

The chamfered surface is the plane of the blanked part with the chamfered edge, that is, the opposite side of the burr surface.

Trial mold refers to the experimental stamping performed after the mold assembly is completed to assess the performance of the mold and the quality of the punched parts.

The roller feeding device is a device that uses a pair of rollers to clamp raw materials and feed them into the die. The feeding of the material is completed by the periodic rotation of the roller.
