| There are few pieces of equipment in any plant that are depended upon as much
as a shear. From the smallest job shop to the largest state-of-the-art manufacturing facility,
a reliable, precise shear is a key part of their success. Their American made, guillotine
style shear has proven itself over the last thirty years to be that key in thousands of installations
all over the world. The Standard Industrial shear gives something that most manufacturer’s
shears can’t, the total satisfaction of knowing they purchased a machine that was 100% owned,
operated and manufactured completely in the U.S.A. |
| The Standard Model AS shear gives you a massive unitized frame in a single fabrication.
This frame consists of the closed end housings, upper cross members, the lower beam, and a table
that together create the strongest design available on the market. The 80,000 P.S.I. steel
capacity is supplied by a single cylinder hydra-mechanical drive system. This capacity
is crucial to meet today’s requirements. The Standard hydraulic system is one of the most
powerful on the market with a large capacity pump and valving to give the operators the most
shearing tons available. |
 |
| This heavy duty system allows you to shear a tremendous range of steel thicknesses
in a single blade gap setting. A set of large, heavy duty, single acting hold-down cylinders
supply all the support required to keep the workpiece in place for the most precise cut.
These cylinders automatically clamp down on the workpiece prior to the movement of the blade.
Narrow material is easily sheared by two cylinders placed side by side on the right side of
the shear. |

Standard Industrial went to great lengths to engineer machines to be the most trouble free
available on the market today. Although powerful, the hydraulic and electric systems are
incredibly simple to keep downtime to a minimum. All components are made from U.S. suppliers
like Square D and Vickers, and we designed them from the vendors’ stock, not specially made
units just for us. Your machine will come with a manual that lists the components original
manufacturer’s name and part number. This gives you the choice to buy replacement parts
that are always available from Standard or from your local hometown vendor’s shelf.
|
| The hydraulic system is designed for quiet, shockless operation to eliminate
the need for special foundation requirements. The shear also comes with system overload
protection to stop damage if an operator attempts to cut more than the machine’s capacity.
Another standard feature is a 36” travel, PLC controlled "Go-To" backgauge with multi-level
programming. This backgauge is undoubtedly the most heavy duty unit available on the market.
It is also available with a 48" travel and/or with a power swingaway which brings the entire
backgauge up and out of the way to shear long pieces. With a long list of other impressive
options and standard features, the Standard Industrial shear will make you proud when you say
that you “bought American. |

Metal plate shears consist of a lower blade (or knife) in a fixed position in the shear frame
and a movable upper blade set into the ram (or top blade carrier) of the shear. The most
crucial aspect to the success of a shear is its ability to properly shear to its rated capacity
over the lifetime of the machine. Four factors are key to this success, (1) strength of
the drive system, (2) strength of the frame, (3) a competent guidance (gibbing) system to bring
the upper blade straight down for the most precise cut and (4) a heavy duty, high tonnage hold
down system. Another important factor is how the blades are held in position securely
during the cut.
Since the lower blade is fixed in the frame, the quality of the cut is entirely dependent
upon the design of the upper (movable) blade carrier. This design is critical to the strength
of the entire system. The two methods commonly used to hold and guide the upper
blade are the guillotine system and the
swing beam system.
The guillotine system is by far the most preferred method used by precision manufacturers
of shears. This system provides the most accurate cutting action due to the fact
that the blade comes straight down to shear the workpiece. The travel of the upper
blade from the top of the travel to the bottom is a straight line through the entire
cut and the angle between the two blades never changes. Virtually all of the quality
U.S. made shears manufactured in this century have been of the guillotine design. The
guillotine system uses ram slides (gibbs) which guide the upper beam and solidly contain
the shearing forces. Our ram slides are located directly above the shearing area on
the front and back of the shear ram above the shearing center line. In this design,
as used by Standard Industrial, the ram is completely contained in the slides throughout
the entire ram travel.
The swing beam system travels at an arc and the angle between the two blades changes
from the beginning to the end of the stroke. The entire upper blade carrier pivots
on two bearings (one on each end frame) in such a manner that the angle of the top blade
varies as the cut progresses. All of the horizontal forces of shearing are transmitted
to the two bearings on the end frames. The swing beam design originated
with lighter capacity shears imported first from Europe and more recently from other
countries. This is most likely due to the fact that it can be designed and made
cheaply to use in the smaller capacity shears. Since the entire front section
of the upper blade is unsupported, it is weaker than the guillotine system and more
prone to deflection and vibration during ram travel. The drive system and blade
carrier are typically lightweight, therefore the system requires the use of an eccentric
adjustment to change the blade clearance for every workpiece thickness.
|
| Although both systems are widely used, the guillotine style possesses the simple
ability to keep the top and bottom blade in alignment at all times which is required for the
most precise cut. We at Standard Industrial have been utilizing the guillotine system
for over thirty years to provide you with a quality 100% American made shear. Models available
up to 20' in length with 1/4" to 1 1/4" capacities. |
