HEAVY-DUTY CAM ACTION
|
MODELS
7-101, 7-58, 7-59, 7-60, 7-61, 7-62
The DE-STA-CO cam clamps have a
high-to-low limit clamping range that automatically compensates for
part thickness variation and therefore eliminates time-consuming
readjustments. The rugged, normalized steel construction allows for
extremely heavy-duty use.
The cam action resists vibrational
loosening. They are built to take abuse. The clamps are available in
six sizes with maximum holding capacities ranging from 475 lbs. up
to 5,500 lbs. Part variation thickness allowance is from 1/8"
(Model 7-101) up to 1/2" (Model 7-62).
Clamp arms may be machined or welded
to suit any application requirement.

HEAVY-DUTY HOLD-DOWN
PRODUCTION CLAMPS
|
SERIES
500
Our Heavy-Duty Clamps offer full flexibility of installation.
Designed for heavy-duty automotive and farm-implement tooling, the
unique construction with heat treated bushings installed in the
outside members of linkage, spread the bearing load over a greater
length for long service. Combined with the forged components, close
tolerance, hardened and ground pivot pins and pivot bolt, they
provide precision repeatability in a compact package.
Five sizes of basic linkage are
available which allows the designer complete flexibility to position
the base, clamp arm and handle, and weld them to suit the
application.
DE-STA-CO now offers Heavy-Duty
Clamps with Toggle-Lock Plus(tm) safety technology. We have taken two
of our most popular Heavy-Duty Production Clamps, Models 501 and
503, and added a locking release lever for improved safety (501-R
and 503-R). The locking release lever helps ensure that the
over-center locking condition is maintained. In order to open each
clamp, the locking lever must first be released. Depending on
mounting conditions, the Models 501-R and 503-R can also be locked
in the open position.

500-LSC Option
A spring clip and urethane bumper
assembly (LSC) is also available in Model 506 and 508 to hold the
clamp arm open under spring tension only.
|
|

HEAVY-DUTY PLUNGER
ACTION

SERIES
670, 675, 690, 695
A unique feature of these clamps
is the collet-type bushing that can be adjusted to eliminate plunger
end movement after long, repeated usage. The plunger also has a flat
which prevents lateral movement and permits offset piloting and
holding. The plunger is drilled and tapped for threaded spindles or
custom fixturing.
A pre-load nut (PL) is optional. This
adjustable nut can be used to cause the clamp to lock against itself
when not under pressure and therefore prevent opening when mounted
vertically. An optional spring hold-open device (S) is also
available to prevent the clamp from falling closed. Spring clip
covers (C) can be ordered which protect the mechanism from chips,
shavings, etc. Available in two styles, Models 670 and 690 offer
longer plunger travel than the shorter Models 675 and 695. All four
models can be ordered with the handle position welded to optional
base (B) at 90o increments -the 0o position being straight up
vertically. Ball handles are standard on Models 670 and 675.
-Heavy-duty - high production clamp
-Adjustable collet-type bushing minimizes plunger end movement
-Pre-load nut optional (PL)
-Spring hold-open device optional (S)
-Designed for accurate repeatability
-Welded handle position optional when base accessory is ordered (B)
- Optional base assembly available for easy mounting (B)
