NUMATX, Inc. manufactures the patented Hydropneumatic Riveter System.   Numatx riveters are lighter and more compact than existing pneumatic only riveters.


Numatx makes high quality commercial grade compression rivet squeezers.  Numatx riveters are the SMALLEST and LIGHTEST aerospace grade C-squeezer and Alligator Squeezer riveters you can buy.  The rivet squeezers are FULLY HYDRAULIC at the forming head portion, which enables the squeezers to be more compact than traditional pneumatic only units.

Watch the below video for a brief over-view and demonstration of the Numatx units.

The Video above shows the feathering control capability of the squeezer (via foot valve).  Initial two advances of compression pin show normal cycle rate, and ability to position compression pin just short of compressing the rivet.

Intensifier unit (not shown) is a Model 3340-1, with air pressure set at 80 psi.  3060-1 Squeezer has an industry standard CP214 compatible 3" reach C-yoke installed.

Shown above are the Model 3080-1,  Model 3070-1, and Model 3060-1.  The 3080-1 and 3070-1 generate approximately 9K and 6K of force respectively.  These squeezers require the higher fluid output Model 3320  Intensifier.  These models accept industry standard CP-214 style yokes.  Weight of the Model 3080-1 is 1.8 Lb, without yoke.
 

WHAT IS THE "HPRS"?

The NUMATX Hydropneumatic Riveter System (HPRS) is composed of a pressure intensifier and various rivet forming heads.  The system uses compressed shop air at approximately 90 psig to generate hydraulic pressure up to 3,500 psig. This substantially higher hydraulic pressure is then used by the forming heads to form rivets or perform other related tasks such as dimpling of skins. The high pressure hydraulic fluid allows for smaller and lighter forming heads over traditional rivet forming tools.

WHAT DOES "HYDROPNEUMATIC" MEAN?

Hy`dro`pneu`mat´ic

a. Pertaining to, or depending upon, both liquid and gaseous substances; as, hydropneumatic apparatus for collecting gases over water or other liquids.


HOW IS THE HPRS DIFFERENT?

Existing powered riveters such as traditional C-yoke squeezers and most blind rivet pullers are integrally packaged, and are relatively bulky and heavy. Different riveting tasks essentially require the user to re-purchase the force generation portion (Intensifier) for each new tool.

The NUMATX Hydropneumatic Riveter System comprises a pressure intensifier, which can be used to power different forming heads, such as a C-Yoke Squeezer and Alligator Squeezer.  For a given force range, the forming heads are lighter and more compact than anything currently on the market.  In this case, smaller is better.
