Chicago Dreis & Krump Hydraulic and Mechanical Powered Leaf Brake machines with push button controls to bend metal and fold metal into many shapes including box and pan shapes.
Below you will see our hydraulic leaf brake machines for bending metal up to 1/4 inch [6.4mm] thick. Scroll way down to see our mechanical power leaf brake machines that have capacity to bend steel up to 3/4" thick. With the push of a button, these metal folding machines will clamp the metal in place and use a hinged apron leaf to fold the metal until the desired angle is reached. They are easier to operate than press brakes and thought to be safer. The metal bending is very similar to a Sheet Metal Hand Brake Machine but with push buttons to tell the hydraulic cylinders to do all the work. A box and pan capable version is available to avoid having the bent sides hit against the clamping bar when the 3rd and 4th sides of a box shape 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.
Basic
Instructions: Turn the handwheel to set the back gauge to the bend
distance. Step on the foot switch to open the clamping bar, insert the
metal against the back gauge, set the dial to the angle you want (or
leave it at 90 degrees), step on the other foot switch to close the
clamping bar, push the bend button and you are done.
Production Instructions: Insert the metal against the back gauge,
push the complete cycle button, and you are done because the machine
will automatically clamp the metal, bend the metal and unclamp. It helps
to have a material table and a finished parts table.

HYDRAULIC POWERED METAL FOLDING MACHINES
A standard metal folding machine needs no die changes. The machine bed supports the sheet metal, not the worker. This makes it less labor intensive than a press brake and therefore is great for short-run, and just-in-time metal bending jobs. Extra thick aluminum sheet metal can be bent. Powerful bends can be made in 10 gauge steel up to 8 feet long. Huge sheet metal panels up to 14 feet long can be bent!
Chicago Dreis & Krump adds hydraulic power with push buttons and foot pedals to convert its famous sheet metal hand brake machines into very productive metal folding machines. You can save time, money and your back with the push button hydraulic power. Two man jobs become one man jobs. They are so easy to operate. A simple to use bend angle 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. Click to see video of the machine

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.

it equipped with NC Controls for back gage and bend angle. This
is the next best thing to owning a Press Brake but without the
high price or tool changes. The Chicago Hydraulic Powered Leaf
Brake will bend up to 1/4 inch thick steel but it can also bend
sheet metal without changing the tooling! Model HBP is designed
to make box shapes and pan shapes up to 6 inches deep. This
machine is easy to use because it works similar to a hand brake
machine. Click to see video of the machine |
 Features: Adustable clamping pressure, adjustable open height, bending leaf gap adjustment, hand wheel operated manual rack & pinion type back gauge with positioning bar or optional numerically controlled back gauge with digital readout. Bend position and bend angle can be stored and changed in the NC control panel. The box/pan capable version has removeable fingers. Minimum reverse bend is 1.18" on 3/16" capacity machine. Minimum reverse bend is 1.37" on 1/4" capacity machine. |
