Blanking is a stamping process, which uses a die to separate a part of materials or working parts from another part of materials, working parts or waste. Blanking is the general name of separation processes such as cutting, blanking, punching, punching, slotting, cutting, chiseling, trimming, tongue cutting, cutting and repairing.

cut

Cutting is a stamping process, which partially separates the material along the open contour, but not completely. The material to be cut and separated is in or substantially in a plane before separation.

side cut

Trimming is a stamping process that trims the edge of a workpiece with a die to make it have a certain diameter, height or shape.

Tongue cutting

Tongue cutting is a stamping process, which partially separates materials along the outline of the opening, but not completely. The partially separated material has a certain position required by the workpiece and is no longer on the plane before separation.

cut off

Cutting is a stamping process, which separates materials along an open contour, and the separated materials become workpieces or working parts.

rotate

Flaring is a stamping process, which expands the opening of hollow parts or tubular parts outward.

perforate

Punching is a stamping process, which separates the waste from the material or workpiece along the closed contour to obtain the required hole in the material or workpiece.

Chongque

Punching is a stamping process that separates the waste from the material or workpiece along the opening contour, and the opening contour forms a gap, the depth of which does not exceed the width.

Cao Chong

Punching is a stamping process, which separates the waste from the material or workpiece along the opening contour. The opening contour is in the shape of a groove, and the depth exceeds the width.

Punching center hole

Punching the center hole is a stamping process to form a shallow concave center hole on the surface of the workpiece, and there is no corresponding protrusion on the backing.

Jingchong

Fine blanking is a kind of smooth blanking, which uses a fine die with a toothed blanking plate to make the whole section of stamping parts completely or basically smooth.

modulus of continuity

The continuous die is a stamping die with two or more stations, and the materials are fed to one station one by one with the stroke of the press, so that the stamping parts are gradually formed.

Single-process die

Single-process stamping die is a stamping die that only completes one process in one stroke of the press.

Combined punching die

Combined punching die is a set of universal adjustable punching dies that gradually form various stamping parts according to geometric features (straight line, angle, arc and hole). Generally, the outline of plane stamping parts needs several pairs of combined dies to be punched several times.

decorate

Embossing is a stamping process, which uses a punch to squeeze one side of a workpiece, forcing the material to flow into the opposite pit to form a bump.

embossing

Embossing is a stamping process in which materials are forced to be partially extruded to form shallow concave patterns, patterns, characters or symbols on the surface of the workpiece. The back of the embossed surface has no protrusions corresponding to the dents.

form

Forming is the general name of stamping process, which changes the shape and size of workpiece through material flow rather than material separation.

Smooth blanking

Smooth blanking is a blanking process that directly obtains the whole or basically all smooth sections without renovation. Torsional bending is a stamping process in which one part of a flat or partially flat workpiece is twisted at an angle with respect to another part.

Edge curl

Crimping is a stamping process that rolls the edge of a workpiece into a nearly closed circle. The axis of a curled circle is linear.

edge curl

Crimping is a stamping process in which the upper edge of a hollow part is rolled into a nearly closed circle.

draw

Drawing is a stamping process to change a flat blank or workpiece into a curved surface, which is mainly formed by the extension of the material at the bottom of the punch.

stretch bending

Stretch bending is a stamping process that realizes bending deformation under the action of tension and bending moment, so that the whole bending section is subjected to tensile stress.

swell

Bulging is a stamping process that expands hollow parts or tubular parts radially outward.

break up

Cutting is a stamping process, which divides the forming process into several parts.

levelling

Leveling is a stamping process to improve the flatness of local or whole plane parts.

Wave forming

Wave forming is a stamping process that relies on the extension of materials to make the workpiece form local depressions or protrusions. The change of material thickness in undulating forming is unintentional, that is, the slight change of thickness naturally occurs during deformation, which is not the requirement of design.

bend

Bending is a stamping process in which a material is plastically deformed under pressure to make it bend into a shape with a certain curvature and a certain angle.

chisel

Chisel is a blanking or stamping process using a sharp-edged chisel. There is no lower die for chiseling, only a flat plate is placed under the material, and most of the punched materials are non-metal.

Deep hole blanking

Deep hole stamping is a stamping process in which the aperture is equal to or less than the thickness of the material to be stamped.

blank

Blanking is a stamping process, which separates materials along a closed contour. The separated materials become workpieces or machined parts, most of which are planar.

throat

Necking is a stamping process, which compresses the opening of a hollow or tubular part to make it shrink.

Do plastic surgery

Forming is a stamping process, which depends on the flow of materials to change the shape and size of the workpiece little by little to ensure the accuracy of the workpiece.

rebuild

Renovation is a stamping process that cuts a small amount of material along the outer contour or the inner contour to improve the edge smoothness and verticality. Generally speaking, the finishing process can also improve the dimensional accuracy.

Hole flanging

Turning holes is a stamping process that turns materials into side flanges along the periphery of inner holes.

revers

Flanging is a stamping process that changes materials into short sides along contour curves.

drawing

Deep drawing is a stamping process, which changes a flat blank or workpiece into a hollow part or further changes the shape and size of the hollow part. In deep drawing, the center piece is mainly formed by the material outside the bottom of the punch flowing into the die.

Continuous drawing

Continuous drawing is a stamping method which uses the same pair of dies (continuous drawing dies) to gradually form the required shape and size on the strip (coil) through multiple stretching.

Refined drawing

Thinning drawing is a drawing process that further changes the shape and size of hollow parts and intentionally thins the side wall.

Reverse drawing

Reverse drawing is a drawing process that turns the inner wall of hollow workpiece outwards.

Temperature difference stretching

Differential temperature drawing is a drawing process which uses heating and cooling means to make the temperature of the material to be deformed much higher than that of the deformed material, thus improving the degree of deformation.

Hydraulic deep drawing

Hydraulic deep drawing is a kind of deep drawing process which uses liquid in rigid or flexible container instead of punch or die to form hollow parts.

rib

Stiffness is a wave-like molding. When local undulations appear in the form of ribs, the corresponding undulating forming process is called rib compression.
