Roll pin punches are designed with a small projection in the center of the pin tip to support the circumference of the roll pin. The tips of roll pin punches are not flat and should never be used on regular solid pins. If a roll pin punch is used on a solid pin, it will mar or mark the pin. If the end of a roll pin punch is damaged or deformed ...
A spring pin (also called tension pin or roll pin) is a mechanical fastener that secures the position of two or more parts of a machine relative to each other. Spring pins have a body diameter which is larger than the diameter of the hole they are intended for, and a chamfer on either one or both ends to facilitate starting the pin into the hole.
The compound tool differs from progressive and stage tools by the arrangement of the punch and die. It is an inverted tool where blanking and piercing takes place in a single stage and also the blanking punch will act as the piercing die. That means punch will be to the bottom side of the tool and piercing punches to top side of the tool.
Green is punch, red is hammer, and blue is trigger slide block. The Adell and Starrett mechanism uses a sliding block crosswise through the hammer rather than an intermediate pin. The hammer has a hole through its center that the top of the punch sits in, and holds the top of the punch centered.
Animation of a power press with a fixed barrier guard. Stamping (also known as pressing) is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape.
A drift is not used as a punch in the traditional sense of the term. Unlike most punches, force should never be applied to the tip of drift pin. Drifts are constructed from wood, light alloys, copper, or steel which are usually rods cut to size as for the job. Drifts can be used to remove dents from inaccessible places, for striking pins and ...
Four small tapered pin reamers. A precision tapered reamer is used to make a tapered hole to later receive a tapered pin. A taper pin is a self tightening device due to the shallow angle of the taper. They may be driven into the tapered hole such that removal can only be done with a hammer and punch.
