Chicago Dreis & Krump Metal Bending Hydraulic Brake Press & Leaf Brake machines, including box and pan making ability.

Press Brake machines commonly use a wedge shaped upper die that force the metal down into the V shaped lower die to bend metal to conform with the tooling. Click for 3 pages of standard Press Brake Dies. A Back Gauge can position the metal exactly where you want it, and the Ram Depth Control is used to stop the upper die at the correct depth to form the angle desired. Sophisticated tooling can be used to form several bends simultaneously. The size of machine required is usually determined by the thickness of the metal and width of the bottom V-die used. Click for Tonnage Table to calculate the size machine you need. Chicago Dries & Krump brake presses use American style tooling and come with a simple 2-Axis CNC controlled back gage and ram die depth control with memory to easily form the same parts again and again. Metal forming can also be done in a manual mode for single jobs. NOTE: Safety devices such as Light Curtains are recommended to prevent fingers and hands from getting crushed especially for predictable repeat uses. Safety compliance is the users responsibility. Click for OSHA Machine Guarding Information.

Scroll further down to see hydraulic and mechanical power "leaf" brakes. These machines clamp the metal in place and use a hinged apron to fold the metal until the desired angle is reached. They are easier to operate than press brakes and thought to be safer. The forming principle is similar to a Hand Brake. A box and pan capable version is available to avoid having the metal hit against the clamping bar when the 3rd and 4th sides are being bent. This is done by removing a clamping bar "finger" at each end of the box since the clamping bar is divided up into many assemblies called "fingers". An insert bar is used to form close offset ("zig-zag") bends.

HYDRAULIC POWERED BENDING BRAKES

Chicago Dreis & Krump brings hydraulic power and push button convenience to its legendary sheet metal hand brake machine family because you can save time and money with the extra muscle. Two man jobs become one man jobs. They are so easy to operate. A simple bend angle control adjustment dial completely eliminates the need for tooling and related time consuming setups. This machine can also form your coated or polished metal without a scratch. These durable, labor saving, high performance work horses are totally self contained. They will accurately bend standard or special design forms and can even make 1/4" reverse bends on light gauge steel with the optional 1/4" insert bar.

STANDARD EQUIPMENT on each hydraulic powered bending brake machine:

Removable Nose Bar Bolted Bottom Bar Compact Hydraulic Power Unit

Angle Bar Insert Bar Oil Level Sight Gauge

Electric Foot Switch - Clamps and unclamps Top Leaf. Allows operator mobility when loading and unloading material.
Bend Angle Dial Adjustment - Adjustable cam and scale that read in degrees, actuates an electric limit switch for bend angle control and repeatability of bends.
Material Thickness Dial Adjustment - Reference scale for speedier set up when adjusting clamping pressure.
Back Gauge - 25 1/2" travel, rack and pinion type with hand wheel adjustment on right side of machine. Inch/Cm scales.
Inch Control - Bending leaf up/down pushbuttons allow complete operator control of the bending leaf motion.
Automatic Cycle - Actuating the "Automatic Pushbutton" clamps the top leaf, raises the bending leaf to the preset bend angle dial adjustment setting, lowers the bending leaf, unclamps the top leaf.
OPTIONAL:
• Extension Fingers (to form inside corners with a return flange across the top)
• Open End Fingers (to form tubes of triangular, square, rectangular, or tapered shape)
• Radius Nose Bars up to 1.5" (great for aluminum)
• Insert Bar - 1/4 inch (for closer offset bends)
• Radius Formers - for forming gutters and mouldings

POWER LEAF BRAKES: bend up to 3/4 thick steel!
Standard, or Box & Pan, in regular, medium and heavy duty capacities. Expensive, but every model we sell includes power clamping and motorized top leafs for maximum productivity. Everything is solidly built to last for many years, from the welded steel plate frames with box type support to the powerful gear head motors with built-in magnetic brakes. These machines offer the kind of staying power and efficiency that includes radius bending abilities usually associated with roll forming equipment or stamping presses. Our Box and Pan versions are just as rugged and stable as our standard models. The sectional, adjustable, finger assemblies even let you easily bend five sided boxes up to 8" deep, and shapes such as tubes. Made in USA. Priced from $70,000.

POWERFUL FEATURES: Power Unit - Powerful, cool running direct drive gear head motor is equipped with built in magnetic brake. Drive System - Self aligning main shaft bearings assure smooth power transmission. Rack and pinion gear transfer power to bending leaf. Power Clamping - Dual air cylinders actuate eccentric clamping links to secure piece part for accurate bending. Power Top Adjustments - Motor adjusts top leaf accurately to thickness of work piece for correct bending radius. Bend Stops - Micro limit switch controls bending leaf travel for repeatable angle bends on the finished work. Operator Controls - Dual operator stations placed at sides of unit for clear view of the qwork area.
