How is a punching machine used in stamping?
How is a punching machine used in stamping?
Stamping is a process in which a press is used at room temperature and a metallic material is sheared by a mold to deform it to obtain a desired shape. Punching machine belongs to the category of forging presses.
What are cutting clearances between Punch and die?
What are cutting clearances between Punch and die?
Cutting clearances between the punch and die are closely defined and specified in the die design stage, based on the requirement of the part. This stamping process produces a very predictable edge condition on the finished part.

What causes a hole in a punch matrix?
What causes a hole in a punch matrix?
Figure 1: If the distance between the punch and the matrix is insufficient, the metal may be dragged or smeared down the side wall of the hole, causing a high-compressive burr. Editor's Note: This is one article in a three-part series. Part I discusses typical causes of premature failure. Part II covers the roles of cutting shear and retainers.

What's the difference between punching and convex stamping?
What's the difference between punching and convex stamping?
Punching: The process of separating the waste from the workpiece along the closed contour to obtain the required holed part. Convex/Compression: A stamping process that uses a punch to squeeze into one side of the workpiece to force material into the opposite pocket to form a bump.

Hole flanging is a punching method that uses a mold to turn the edge of the hole of the part to an upright or a straight edge at a certain angle.
Depending on the shape of the blank and the edge of the hole being flanged, there are flanging holes on the flat plate, and also on the curved surface, such as the flanging hole on the tube blank; the flanged holes can be rounded or non-rounded.
Deformation characteristics of round hole flanging:
The forming limit is expressed by the hole-flanging factor K:
Factors affecting the limit hole flanging coefficient:
(2) Process arrangement for round hole
Usually, before flanging the hole, it is necessary to pre-punch the hole for the hole-flanging, and then determine whether it can be turned at one time according to the height of the hole and the coefficient of the hole-flanging, and then determine the forming method of the hole-flanging parts.
(3) Process calculation of plate hole-flanging
1) Determine the diameter of the pre-punched hole
2) Calculate the height of the hole to determine whether the hole can be successfully turned once.
3) Determine the number of turning holes
