Point of Operation Guarding
The machine must not be operated without point of operation guarding. It is the responsibility of the user to insure the machine is operated safely and has appropriate guards for the type of work being performed. The manufacturer can not satisfy the guarding requirements for the many and varied applications these machines can perform. The manufacturer will assist the purchaser with his selection of guarding and will offer factory installation of the guarding selected by the purchaser.
Swing Beam Principal
The top beam of this type of machine is located by two precision self aligning spherical bearings. this design concept eliminates the need for slides and guides and is known as the "swing beam" principal. The steel weldment is a fully enclosed "boxed" section which becomes an extremely rigid member supporting the top knife.
After many years of experience with the "swing beam" we have developed the geometry of this design with many superior features. We believe our machines are the only ones using the swing beam design and having both upper and lower four edged knives, which has the top knife meeting the material being sheared with the square corner of the knife at 90 degrees to the shearing surface. On all other machines known to us, the top knife shears through the material on a slight angle and their knife geometry causes the corner of the knife to crush an indentation along the sheared edge during the shearing operation.
The effect of this crushing produces the stresses in the material which causes distortion in the piece cut off.
The SH-2000 can cut a 2" strip of 1/4" plate
with no distortion.
The entire hydraulic system is to JIC standards and makes maximum use of flared fittings, installed with the ultimate in simplicity and accessibility to servicing the circuit components. The electric motor, hydraulic pump, valves and piping are mounted as a self-contained module in the power unit and may be swiftly and easily replaced with an exchange unit to simplify reconditioning or service work in the distant future. The hydraulic oil tank is designed for operation on 100% duty cycle, with sufficient oil capacity to dissipate any significant temperature rise above normal operating levels.
The control panel features a lockable mode selector to provide "Off", "Inching" and "Single Cycle" functions. In the Off position the machine is completely inactive. The Inching mode allows the operator to gradually move the top beam down to check the work prior to taking the cut or to facilitate checking knife clearance when this may become necessary. This function can also be used to maintain hold down pressure after taking a cut to allow the operator to support the material on the table and prevent it from falling after the hold downs have released.
Knife Clearance Adjustment
A two-point knife clearance adjustment is provided as standard equipment. However, because of the basic design and structural rigidity of these shears, virtually any thickness of stock can be cut - to the maximum capacity - without adjusting knife clearance.
Being mounted on eccentric pins or cams, the bearings serve as a simple knife clearance adjustment. These two bearings are the only two critical wearing points in the entire machine design. On larger capacity shears where frequent changes in knife clearance are necessary, clearances can be altered swiftly and accurately to graduations shown on a knife clearance indicator.
Stroke Length Adjustment
By means of a simple thumb screw the stroke length may be adjusted to reduce cycle time and increase productivity on shorter work by as much as an additional 80%.
CNC Back Gauge System
SH-2000 and SH-3000 Back Gauge Range = 36" (Standard)
SH-4000 and SH-6000 Back Gauge Range = 48" (Standard)
SH-8000 Back Gauge Range = 48" (Standard)
Choice of Table Styles
Fully machined flat table with hand slots. (Type 1)
Ground table plates, adjustable height. (Type 2)
Combination ball transfers and ground plate. (Type 3)
The frame and all attachments are fabricated from high-quality steel to produce a virtually indestructible assembly. Extreme strength and rigidity are designed into the frame. The table is a fully-enclosed box section welded between two high strength side frames.
Bearings & Gears designed into the machine make maximum use of proven materials which are known to ensure long life with minimum lubrication. Most applications have no need for any lubrication and almost all the bearings are self aligning type.
The hydraulic system is the ultimate in simplicity, using only one pump,
two control valves and a pressure control valve. Overload protection is set
during factory testing procedures and eliminates the possibility of breakage
caused by inadvertent misuse. Balanced hydraulic system eliminates
torsion in frame.
The electric system has a 115 volt control module separate from the 230/460 volt motor starter circuit. Both circuits have quick change components and also can be simply replaced as complete exchange modules.
