This can result in a considerable time saving

(varying by vehicle type) over conventional

methods.

The ratchet drive of the

product features automatic

advance of the cutting

wheel with every turn,

making the cutter easy to

use and ensuring optimum

results, even in the most

inaccessible

situations.

The special alloy of the

cutting wheel gives a long tool-edge life and

ensures fast work, while the body of the

pipe cutter is made from rugged, easy-care

die-cast aluminium.

The Dako number 224 ratchet pipe cutter

is designed for parting plain steel, stainless

steel, copper and aluminium tubes, and is

available in two sizes: one for pipe of 16mm

to 35mm diameter, and one for 35mm to

66mm diameter, with wall thicknesses from

1.5mm.

Pipe benders for demanding

shipbuilding application

Eagle

Precision

Technologies

Ltd,

Canada, has designed, manufactured and

delivered a CNC pipe bending machine

for a shipbuilding application in Asia.

The application required the bending of

numerous different part shapes on small

runs, including the production of a part

with a 1.5D bend (109mm bend centreline

radius) using 73mm OD x 4mm wall

stainless steel pipe.

Eagle’s EPT-150 CNC pipe bender

The challenge was to bend this pipe

while meeting the customers exacting

requirements for ovality of 8 per cent or less,

and wall thinning of 12 per cent or less. This

had to be achieved without producing any

wrinkles on the inside of the bend, and with

minimal scrap.

Eagle designed a custom EPT-100 XPH

(100mm capacity) CNC hydraulic pipe

bender featuring a high torque, robust bend

head to handle the high torque requirement

of the application. For loading the heavy

wall pipe, Eagle reduced the load height of

the machine for easier operator handling.

A programmable follower was supplied to

provide boost assistance to maintain the

Collaring in the automotive industry

T-Drill, Finland, a manufacturer of tube processing and chipless tube cutting machines,

has reported increased deliveries of its S-54 collaring machines for automotive engine

cooling tube, fuel rail and exhaust circulation applications.

The T-Drill collaring method provides reliable and easy T-joining of tubes. This is of

great importance in automotive applications, where every vehicle is subject to severe

vibrations that can create leaks and other

problems with traditionally made T-joining

using saddle-adapters or drilled holes.

Due to the increased lapping length between

extruded collar and branch tube, the lapping

joint length is increased by three times. With

capillary action, this provides a reliable brazed

joint.

T-Drill’s extruded outlets are formed only

outside the main run tube. This eliminates

flow restrictions that are common with other

forming operations.

Ratchet pipe cutter for automobile retro-fitting

The number 224 ratchet pipe cutter from

Dako, part of the Gedore group, Germany, is

suitable for retro-fitting catalytic converters

and soot particle filters, and for replacing

parts of vehicle exhaust systems.

Depending on the surrounding area, the

exhaust simply needs to be pulled down

far enough to allow room for the cutter

head to rotate around the pipe. No sawing

or grinding is required, eliminating the

risk of injury to the user and avoiding any

possibility of the underside of the vehicle

being damaged by sawing or grinding. The

cutting produces no swarf, so that no chips

or swarf can enter the exhaust system.

The cut is clean, so new sections

of exhaust can be fitted

immediately after the pipe

has been parted off.
