Blanking is a stamping process that uses a stamping die to separate parts of material or process parts from another part of material, work (order) or waste material. Blanking is cutting, blanking, punching, blanking, punching, cutting, renovation and other separation procedures.
Cutting is a method of stamping material along an open contour rather than a complete separation. A material that is cut and separated; located at the plane in front of separation.
Cutting edge is a stamping process that uses the edge of the die to trim the edge of the forming process so that it has a certain diameter, a certain height or a certain shape.
Cut the tongue
The cutting tongue is a kind of stamping process that divides the material along the open contour rather than completely. The locally separated material has a certain position required by the workpiece and is no longer located on the plane before separation.
Cutting is a stamping process in which material is separated along an open contour, and the separated material becomes a workpiece or a work piece.
Expansion is a hollow piece or tubular parts open at the outward expansion of s tamping process.
Punching is a punching process that separates waste material from material or process parts along closed contours and gets holes in material or process parts.
Blanking is a stamping process that separates waste material from the material or process along an open contour, and opens the outline to form a notch with depth not exceeding the width.
A groove is a stamping process that separates waste material from the material or process along an open contour, with an open profile in a groove with a depth exceeding the width.
Center punch hole
The punching center hole is a punching process for forming a shallow concave central hole on the surface of the work piece, and the back material is not raised correspondingly.
Fine blanking is a kind of bright and clean blanking. It uses the fine blanking die with toothed press plate to make the whole face of the stamping parts all or almost all clean and bright.
A continuous die is a die with two or more stations. The material is sent into a position successively with the stroke of the press so that the stamping is gradually formed.
Single process die
A single process die is a die that completes only one process in a stroke of a press.
The combined die is a universal and adjustable die set which is formed by the geometric elements ( straight line, angle, arc and hole). The outline of flat stamping parts usually requires several pairs of punching dies.
A convex pressing is a punching process in which a punch is inserted into the work piece to force the material to flow into the opposite pit to form a bulge.
Embossing is a kind of pressing process that draws out the material and forms a shallow concave pattern, pattern, character or symbol on the surface of the work piece.
Bright and clean blanking
Bright and clean blanking is the whole or all clean cutting process which is obtained direclty without renovation. Twist is straight or straight part of local process relative to the other part of the torsion angle of stamping process.
Crimping is a stamping process that moves the edge of the work piece into a closed circle. The round axis of the reel is in a straight line.
The roll edge is a punching process that turns the hollow edge of the hollow piece into a closed circle.
Drawing is a kind of stamping process in which flat or working parts are changed into curved surfaces, and the surface is mainly formed by the extension of the material at the bottom of the punch.
Stretch bending is a kind of stamping process under which the bending deformation is realized under the combined action of tension and bending moment, and the whole bending cross section is all subjected to tensile stress.
Bulging is a pressing process that expands hollow parts or tubular parts along the diameter.
Cutting is a kind of stamping process which divides the forming process into one part.
Leveling is a stamping process to improve the flatness of a part or whole plane.
Roll forming is a stamping process that relies on the extension of materials to make the process parts form a local depression or bulge. The change of material thickness in the forming process is non intentional, that is , a small change in thickness is formed naturally in the deformation process,not a specified design requirement.
Bending is a kind of stamping process that uses the pressure to deform the material and is bent into a shape with a definite curvature and angle.
Cutting is a blanking or punching process using a chisel cutting stamping die. There is no lower die, but only the flat plate under the material, and the majority of the punching material is nonmetal.
Deep hole blanking
Deep hole punching is the punching process when the aperture is equal to or less than the thickness of the punched material.
Blanking is a stamping process in which material is separated along a closed contour, and the separated material become a workpiece or a work piece, most of which are planer.
Necking is a pressing process that reduces the opening of hollow parts or tubular parts.
Plastic is a stamping process that relies on material flow, a small amount of change in the shape and size of process parts to ensure the accuracy of the workpiece.
Refurbishment is along the profile or contour cut a small amount of material, so as to improve a punching edge roughness and verticality. The repair process also improves dimensional accuracy in general.
The turning hole is a stamping process that transfer material to the side vertical flange along the inner hole.
Flanging is a stamping process that turns material into a side and a short edge around the curve.
Drawing is a process of turning a flat or work piece into a hollow piece, or further changing the shape and size of a hollow part. The drawing time and space parts mainly depend on the material outside the convex die to flow into the stamping die.
Continuous drawing is a kind of stamping method which uses the same die (continuous drawing die) to form the required shape and size by drawing repeatedly.
Thinning and drawing
The thin drawing is a kind of drawing process that further changes the shape and size of the hollow working parts and deliberately reduces the side wall.
Reverse drawing is a kind of drawing process that turns the inner part of the hollow work piece off.
Differential drawing is a kind of deep drawing process, which uses the heating and cooling methods to make the material to be deformed much higher than the temperature of the material that has been deformed so as to improve the deformation.
Hydraulic deep drawing
Hydraulic deep drawing is a kind of drawing process which uses the liquid in the rigid or flexible container instead of the punch or the die to form the hollow parts.
The bar is a kind of undulating forming. When the local fluctuation occurs in the form of reinforcement, the corresponding fluctuation forming process is called the reinforcement.
