Multicyls are used for many types of tube pierce applications. The following chart illustrates the 5 most common. Scroll down for details on each of them.
H1 Single Dimple & H2 Double Dimple Hole Applications
Multicyl offers a range of standard tube pierce stations for H1 and H2 punching systems, one of our most popular applications. Standard systems accommodate round or shaped parts up to 1.5” in size. Custom larger systems may also be quoted upon request. Front feeding of the tube makes it possible to pierce parts after forming. The tooling uses upper and lower guides which encapsulate the tube to prevent OD distortion. Guides and punches are easily interchangeable to allow a single unit to perform various applications. An H1 system is easily converted to an H2 system by adding a punch assembly to the bottom guide. H1 and H2 tube pierce stations are the most cost effective method of punching holes in tubing. Important information when requesting a quote for this application includes: tube diameter, material and wall thickness, hole diameter, hole location, and application number (H1 or H2).

H3 Straight Through Hole Applications
Multicyl straight through tube pierce stations produce a through hole which is dimpled on the top and clean (no dimple) on the bottom. H3 stations are similar to their H2 counterparts except that rather than housing a second punch the bottom guide contains a die button to produce the clean bottom hole as the punch is powered straight through from the top. Maintenance may be higher with this application as the punch tip is significantly longer and the bottom hole is actually punched with the slug from the top hole. Because of the longer distance that the punch must travel in this application longer stroke cylinders are used and applications are limited to tubes with 1.00” maximum diameter (front feed) or 1.25” maximum diameter (side feed).
