Production & P rocessing of Automotive Tube
May 2009 70 ›
Menegon Ennio sas, Italy, is the manufacturer of special units
for hydraulic drilling and cutting, and tube/component transfer.
Designed for the automotive industry, the equipment offers
specialist functions such as scallop cutting, shearing, and drilling
with radial pass and linear units.
With advanced R&D capabilities, the company is also a specialist
in the production of complex stainless steel moulds. In addition to
the automotive industry, the equipment is used in the fields of food
production, appliances, construction, furniture and agriculture.
The company’s lines are used for automotive production, offering
functions such as scallop cutting, shearing, folding and tracing. The
machine is divided into nine stations with different productive cycles.
These stations include departure point, single perforation, double
sided perforation, control and cleaning of holes, tablet insertion and
folding, calibration, branding, control and unloading.
Menegon also offers a special unit for hydraulic drilling of tube and
sheet. This machine provides scallop cutting, shearing of straight
and inclined tubes, folding, and drilling tubes with a radial pass
and linear unit. Features include high quality, advanced parts,
hydraulic operation without springs during closing and extraction,
and low maintenance. The addition of more units is easy due to
the modular system. The blocking of pieces to drill is guaranteed
by the mechanical closing of the dies, with accurate movement
and automatic centering of the material. The closing of dies is
interchangeable and the machines allow the drilling of tubes up
to 30mm in diameter (with 90° rotation). The functioning principle
guarantees mechanical extraction of pieces because the punch
completely re-enters in the same position while the dies are in
position.

Automated non-destructive testing systems
NDT Technologies Inc, Canada, is the manufacturer of a range of
automated non-destructive testing systems, precision measuring
and material handling. The company has launched an automotive
engine cylinder liner flaw detector. The inspection system is
designed for offline detection of internal and external flaws in
automotive engine cylinder liners.
The system uses the eddy current flaw detection method for the
detection of micro-cracks, surface imperfections and sub-surface
flaws. Defective parts are diverted to the reject chute.
NDT Technologies has also introduced an automotive hollow shaft
flaw detector. The EddytronTM is designed to inspect aluminium
steering column casting for internal surface flaws in the body, and
in the hydraulic seal seat chamber.
The casting is used for power steering applications in automotive
industry. Due to the operational importance and highly complex
geometric shape of the cast part, stringent quality control
parameters need to be implemented. The system provides
electronic evaluation of changes in eddy currents (due to
imperfections) that are present on material surfaces.
The method is sensitive to changes in distance between the probe
and the material, requiring a high level of manufacturing precision
on the probe guidance system. Flaws as small as 0.2mm deep can
be detected. In order to achieve test consistency, calibration speci-
mens containing artificial flaws of known dimensions are supplied.
