Functional sequence of the pierce nuts
All tool components are retrieved from a standard modular system. In this way, project-related punching heads and dies can be matched within very short time. There are different systems for feeding the nuts. The best possible solution can be configured for every part or every customer.
The simple but intelligent design of all system components ensures reliable function at all stages of the process. This system is used in innumerable volume production applications in the automotive, household appliances and electrical industries. In some applications, the automatic punches install up to 600 nuts a minute or up to 30 nuts in one stroke in large parts processed on press lines.
Critical to the success of a project is the early and close cooperation among all involved parties. The advantages of the PIAS® system should be considered already at the design and development stages of a project.
- Die Einstanzmutter ist im Stößel geklemmt. Die Weiche ist verriegelt. Der Stanzkopf fährt abwärts auf das Blechteil.
- Der Anschlag setzt auf das Blechteil auf. Der Stößel fährt abwärts auf die Matrize.
- Die Mutter stanzt das Blech. Der Stanzabfall wird durch die Matrize abgeführt.
- Der Stößel bewegt sich nach oben in Grundstellung, das Blechteil wird entnommen.
- Die Weiche ist geöffnet, eine Mutter wird in die Klemmen des Stößels nach geschoben. Der Stanzvorgang kann von neuem beginnen.
This function sequence describes a Picasso I punch head with locking feature. Available on a regular basis are also the variants Picasso II without locking feature for use with C frames, Picasso Auto for application with RXM piercing nuts, as well as Socrates for application with PN nuts.
In addition, Arnold & Shinjo is supplying a large number of punch head variants, for instance double or block punch heads.
Should your component part be of a particular geometry which cannot be implemented with standard tooling, special punch heads can be designed and supplied as required.
