(2) Bending the die makes the blank or other blanks bend and deform along a straight line (bending line), thus obtaining a die with a certain angle and shape.
(3) Drawing die is a die that makes the blank of sheet metal into an open hollow part or further changes the shape and size of the hollow part.
(4) The forming die is a die for directly copying and forming a blank or semi-finished workpiece according to the shapes of the male die and the female die, and the material itself only produces local plastic deformation. Such as expanding die, necking die, flaring die, wavy forming die, flanging die, shaping die, etc. (1) Single-process stamping die A die that only completes one stamping process in one stroke of the printing machine.
(2) The compound die has only one station, and in one stroke of the press, two or more stamping processes are completed at the same station at the same time.
(3) The progressive die (also called the continuous die) has two or more stations in the feeding direction of the blank, and in one stroke of the press, two or more stamping processes are continuously completed at different stations.
Progressive die (progressive die) is a cold stamping die that uses strip-shaped raw materials in one stamping stroke and completes multiple stamping processes at several different stations on a pair of dies at the same time. Every time the die is punched, the material belt moves at a fixed distance until the product is finished.
In the process of continuous die stamping, the material belt always moves in one direction; Progressive die means that the material belt in the die moves in two or more directions after cutting. Call the automatic continuous die when the material belt enters the die; In the stamping production chain, the manipulator or other automation facilities used for stamping dies with different processes are used to move dies or parts to complete the stamping of workpieces. Rated dies are called multi-station dies.
