1. HYDRAULIC HOLDDOWNS The holddowns are arranged more closely on each end of the machine to insure proper clamping of small pieces while being sheared They also operate independently to compensate for any plate thickness varia tions and feature nylon padded feet to pre vent marring of polished or soft materials BALL TRANSFERS Spring loaded ball transfers are provided to ease posilioning of heavy plate for shearing SHEARS STANDARD EQUIPMENT RAKE ANGLE CONTROL The rake angle conirol is located near the bottom of the control box and is displayed via a digital display ADJUSTABLE RAKE Power adjustment of the rake angle at the controls allows thin material to be cut at less angle minimizing deformity of the sheared Stock BLADE GAP ADJUSTMENT Quick blade gap adjustment is achieved by moving the adjustment levers to the desired setting 4 EDGED BLADES Standard equipment includes 4 edged blades providing 4 new edges per blade before re sharpening is re quired Upon resharp ening Ihey are ground on the sides eliminat ing any need for shim ming Blades are pro vided In HC HC or shock resistant hi Alloy depending upon model of shear POWER BACKGAUGE A front operated power backgauge with a range of 1 1o 39 is included Acme screws with adjustable nuts are used providing Su perior rigidity and accuracy The backgauge also retracts automatically as d2. 26 5 19 3 A 12 5 tv 23 42 7 31 2 23 8 19 5 116 3 12 4 9 6 45 5 35 2 8 5 24 4 17 4 15 0 48 5 39 5 33 2 24 6 19 5 20 18 16 13 12 11 10 9 7 5 0 313 3A 0 375 Tj 0 438 14 0 500 5A 0 615 34 0 750 Tg 0 B75 1 5 000 SPECIFICATIONS HDBU 6 5i HDBO 10 8 MDBO 12 10 HD 100 6 0100 8 6 HD100 10 8 HD100 12 10 HDt65 10 8 HD16 12 10 165 144 122 6 HO165 14 12 4 HOR SU 15 B HO200 12 10 200 14 HOQ200 14 12 HO2 0 10 8 Ho 50 12 10 2 amp 0 HD250 14 12 MHD300 10 8 HD3060 12 19 4 14 32 990 WD300 168 54 HD450 10 8 0450 12 10 110550 14 12 450 HOSS 1G 14 1450 20 18 65 5 57 9 42 8 33 1 27 3 23 3 17 0 92 3 68 1 3 0 43 2 36 2 26 9 21 0 103 1 79 9 63 9 52 3 39 2 31 2 112 1 90 4 75 5 55 7 43 7 Press Brake rear view STANDARD EQUIPMENT All Steel Construction Allen Bradley Electrics Power Stroke Adjustment Portable Foot Control Hydraulic Fluid Infinite Pressure Adjustment Inch Control Rapid Advance Speed Slow Pressing Speed and Rapid Return Mechanical Stops in Cylinders Machines wired for 220 440V 3 phase operation Specify voltage needed HYDRAULIC PRESS BRAKES STANDARD EQUIPMENT POSITIVE CYLINDER STOPS All machines have positive adjustable sto
