Frame and Base: Side frames are welded to the table base assembly as a closed end type, which is standard. With the gap end option, base of end housings have provisions to anchor machines to flat surface. The upper knife is manufactured with means of adjustment for obtaining and maintaining clearance adjustment between upper and lower knives. Mounting holes in the feet allow for firmattachmentto the floor and leveling of the machine. 

 

Table: The table is constructed of fabricated steel, which is flat to ±0.005 inch per linear foot. The standard table is solid for the first 24 inches on the right side with support beams 16 inches on center for balance of machine. 

Options: 

1. Solid table top bolt on segments 

2. Machined bed 

3. Hand slots (optional where specified) 

4. Ball transfers (available in any of the table top patterns - open, bolt on segments or machined solid table top) 

 

Ram: The ram is guided through the shearing stroke by a bronze slide assembly and a steel assembly. The assemblies guide the ram on a vertical shearing plane with 2 angular degrees off the shearing plane of the stationary knife. The bronze slides have a large surface area to dissipate pressure per square inch. The PSI is low in comparison to machines that use swings or have many pins and little area to dissipate the pressure. Optional non-metalic slide assemblies are available to replace bronze. 

 

Hydraulic System: The hydraulic system is designed for the capacity of the rated machine to JIC standards. The hydraulic system has safety overload protection. Hoses, tubes and fittings are rated at no less than 150% of the rated working pressure. 

​

Hydraulic Cylinder Drive: There are two direct acting hydraulic cylinders for directing the ram. The hydraulic cylinder drive has double acting pistons and ball sockets for self-aligning joints. 

Hydraulic Hold Down System: On the 1/8” (10 GA), 3/16” and 1/4” machines the hydraulic self-compensating spring plunger bar assembly has plungers every 4 inches for the first 24 inches and plungers 8 inches on center for the remainder of the bar. On 3/8”, 1/2”, 5/8”, 3/4”, and 1” machines, the plungers are spread every 5 inches for the first 24 inches and plungers 8½ inches on center for the remainder of the bar. The hydraulic holddown system automatically secures the workpiece during ram down-stroke and releases on return stroke. Optional independent holddown control is available. Refer to chart for the number of plungers. 

 

Reservoir: The reservoir features combination level and temperature gauges and a cleanable filter system capable of removing particles 10 microns in size. 

 

Shear Knife: Our knives are made of a shock resistant grade of modified high carbon, high chrome with four edges. Harder grade of high carbon, high chrome is available. 

Controls: Controls include: 

1. Pull to start, push to stop. 

2. Jog (inch)- Single stroke – run
           Optional: Continuous stroke 

3. Single palm button for stroke 

4. Backgauge controls:

   • forward/reverse 

   • variable speed 

5. Emergency up-switch

Rake Angle and Rake Angle Adjustment: Power rake angle adjustment is standard. Angle is maintained throughout cutting cycle, when rake angle is adjusted to require angle. Refer to chart. 

Increased adjustable rake angle is standard on all machines to allow for cutting of harder and heavier material. 

 

Electrical System: The electrical systems meets NFPA 79 standards. All machines have disconnect switches, magnetic starters, 110/120v controls, 208-230/460v 3 phase, others optional. 

 

Motors: Motors are open drip with sealed and permanent lubricated bearings. 

 

Control Circuit Voltage: Control voltage is 110/120v supplied by a transformer. 

 

Backgauge: 36” power operated backgauge is standard. Controls are located on front of the machine. 5 Station NC “GO-TO” Positioner is standard. 

 

Front Support Arms (Optional): Front support arms are available with or without scales. 

 

Squaring Gauge: 4’ squaring arm on right-hand side with scale is standard. Left-hand squaring arm and longer gauges are optional. 

 

Angle Gauge (Optional): Angle gauge marked in 1/2° increments. 

 

Light Beam Gauge (Standard): Shearing gauge utilizes light beam shadow as the shearing line. 

 

Capacity: Machines are based on 80,000 pounds tensile. Other options are available upon request. 

 

Shearing Accuracy: The Betenbender Hydraulic Shears will meet or exceed shearing accuracy of material ranging up to the full width capacity of the machine to precision tolerances. The width of the sheared workpiece shall be within ±0.005 inch of the backguage settings. 

 

Safety Features: The Betenbender Hydraulic Shears are built to meet ANSI B11.4 standards. Some of the safety features of the Betenbender Shears are: 

• Finger Guard for holddown w/ safety switch 

• 110/120v control 

• Guarded foot petal 

• Warning signs, safety markings & covers 

• Electronics meet NFPA 79 standards 

• Central systems provide the operator with complete control to stop & reverse the ram by simply releasing the control 

• For multiple operators, a separate control for each person, can be provided within reach of the machine 

• Emergency up-switch on control panel 

 

Specifications are subject to change without notice. 

 

Compliance with OSHA requirements is the legal responsibility of the user and is subject to local inspectors’ interpretation of existing standards.
