1673  small

June 2020- Reducing, Swaging and Expanding Tube… The Magical Formula!



1673 Swager-reducer-expander machine surpasses competitor's machines at creating the end finishes to connect pipes and tubes either together or to something else. The Huth Machine has the capabilities of creating many different end finishes to connect your pipes and tubes and create one-of-a-kind end finishes or repeatedly create a precision end finish.

 

Below are ABBREVIATED instructions for creating some of the many different end finishes you or your team can make with the Huth Machine. Sometimes it’s easier to learn through demonstration, and for that you can watch the 1673 Video and other Huth demonstration and training videos on our HuthBenders YouTube channel.


For full detailed instructions, please review your Huth machine manual (these are a brief overview!)

 

These are the end finishes your Huth Machine can create:

  • Swage (pronounced Swedge) Die – enlarges tube/pipe end diameter 
  • 45 degree Flare/flange
  • Flat (90 degree) Flare/flange    
  • Female Ball Joint
  • Male Ball Joint
  • Tube Reduction
  • AccuSizer

Swage Die (Click to watch video)

To enlarge a tube or pipe to a deep inside diameter

 

1) Install the swage die by screwing it onto the cylinder shaft in the swage box

2) Secure your tube/pipe with the proper clamping collets

3) Close the safety guard. Then operate the ram.

4) Move the cylinder forward slowly until the tool enters the tubing/piping

5) Continue to move the shaft forward until the tool reaches the desired depth.    

 

Note on swaging depth: Huth has tooling for normal (approx. 2 inch) or deeper (up to 4 inches on tube OD’s over 1 ½ inches) swages.

 

Reducing Die (Click to watch video)

To reduce the inside diameter of a tube or pipe

 

1) Install reduction swage die by screwing it onto the cylinder shaft.

2) Secure your tube/pipe with the proper clamping collets

3) Close the safety guard. Then operate the ram.

4) Move the cylinder forward slowly until the tool slides over the tube/pipe

5) Continue to move the shaft until the reduction has been formed

6) Don’t go too deep, or it will crush the tube/pipe!

 

45 Degree Flare/Flange (Click to watch video)

(Process example. Use same process for different diameters)

 

1) Attach tool 853, onto the 815 die holder, with the 45 degree flare facing forward.

2) Insert tube/pipe and clamp down. Place safety guards.

3) Slowly bring the tool up to the tube/pipe

4) Tap the control handle and move the cylinder shaft forward until the desired flare is formed

5) Retract cylinder shaft and remove tube/pipe.

 

Flat Flare/Flange (also called 90 degree flare or flange) (Click to watch video)

Two operations are necessary to create a Flat Flare:

 

1) Follow the directions to create a 45 degree flare.

2) Retract the cylinder, but leave the tube/pipe in place.

3) Reverse tool 853.

4) Use the control handle to slowly bring the tube/pipe forward until the flare forms a flat surface.

5) Retract cylinder shaft and remove tube/pipe.

 

Female Ball Joint (Click to watch video)

1) Attach proper female tool to tool 815 and secure tube/pipe into clamps with proper collets. Place safety guards.

2) Slowly bring tool forward until it starts forming joint

3) Tap the control handle until it bottoms out on the ridge

4) Retract the cylinder shaft and remove tube/pipe.

 

Male Ball Joint (Click to watch video)

Two operations are necessary to create a Male Ball Joint:

 

1) Attach proper male ball joint tool to the end of the cylinder

2) Secure tube in collet holder and place safety guards

3) Slowly insert tool forward and tap until tool reaches second marking line

4) Retract tool

5) Dome the end of the male ball by using the 557 die with the domer die attached to the 815 to create a completed male ball joint

 

AccuSizer – Make precision expansions

(Click to watch video)

With Huth’s Accu-Sizer system, you can dial in precise expansions every time. The AccuSizer can be used to quickly and efficiently create some of the following end finishes:

 

45 degree Flare with AccuSizer

(Click here to watch video)

The AccuSizer allows you to make a flared end finish very close to a bend

1) Attach the 508 arbor with the 499 arbor tip and 440 flaring segment set

2) Insert tube/pipe and clamp down. Place safety guards.

3) Slowly bring the tool up to the tube/pipe

4) Tap the control handle and move the cylinder shaft forward until the desired flare is formed

5) Retract cylinder shaft and remove tube/pipe.

 

Male/Female Ball Joints with AccuSizer

1) Use the correctly sized arbor and tip (Both male and female are made with the same segment set).

2) Install the proper ball joint segment set, according to your tube/pipe diameter

3) Insert tube/pipe to the base of the segment set to create a Male Ball Joint and clamp down. OR Insert the tube/pipe to the groove on the ball to make a Female Ball Joint.

4) Place safety guards.

5) Tap the control handle and move the cylinder shaft forward until the desired flare is formed

6) Retract cylinder shaft and remove tube/pipe.
