into consideration our clients wishes, every day we work to satisfy
our Clients' needs, to increase our product list and tools
quality. 1).LEJIA produce bending tools from high speed steel
high quality steel(42CrMo=SCM440=42CrMo4=4140), working surfaces
are preciously grounded, standard will be whole body Total
Hardening, the hardness can reach HRC47;2).We can do surface
hardening on bending tools by Laser, the the hardness can reach
HRC60.3). LEJIA have we have more than 20 years experience in
bending tooling manufacturing.4).LEJIA bending tooling factory
total have More than 300 people, total have around 310 sets
processing machines for bending tools. most processing machines are
from Japan and Europen;5).LEJIA bending tool accuracy: Center
Accuracy:±0.02mm, Parallel Accuracy:±0.02mm, Vertical
Accuracy:±0.02mm6).Every special bending tooling will be tested by
our press brake machines and have the testing samples before
sending to our Clients.3. TYPES OF PRESS BRAKE TOOLSTools for press
brake are considered "safety first", and dies with fall prevention
grooves are now standard.Typical punch clamp typesSAFETY
BUTTON Bending edge shapesSTANDARD PUNCH,GOOSENECK

PUNCHTypical die types and mounting methods 1V Die, 2V Die, 4V
Die4. TOOL LENGTH Types:1).L = 835mm, S = 415mm, A section = 835mm
and B section = 800mm 2).550mm,
1050mm,1250mm,2050mm,2550mm,3050mm,4050mm5. HOW TO READ THE TONNAGE
CHARTCheck the tonnage chart before Bending.The tonnage chart is
always specified in the tool catalog, and is also displayed on the
machine as a nameplate where it is easy to see. Basically, you
can read the conditions other than pressure in the chart
below.Knowing this tonnage chart deeply or shallowly will make a
big difference in worker safety and product finish.It greatly
affects machine specifications, tool selection, product accuracy
and quality, so let's grasp the contents and use them for safe
work. First of all, read the following contents from the chart
below.1: Minimum flange length (b) 2: V-width (V-opening) of
tool used for bending (V) 3: Required tonnage to bend 1m long

par meter (kN/m)The values in the tonnage chart are based on
"bottoming" and "SS material", so the tensile strength
etc. must be taken into account depending on the processing
conditions.The values in the tonnage chart are based on "bottoming"
and "SS material", so the tensile strength etc. must be taken
into account depending on the processing conditions.6. MINIMUM
FLANGE LENGTHTo complete the bending, the material must be on
both shoulders of the die to the end.The minimum flange length is
expressed by the following formula based on 90° bending.b=( V/2 ) x
√2≒0.7V7. V width selection and basic setting of ir (inner

thicknessecause of the bending process that is used most often, the
patterns for V-grooves are also finely divided.0.5 - 2.63.0 -
8.09.0 - 106×t8×t10×tPartial Bending12 - 15×tSince an arbitrary
angle bending is taken into consideration, the V-width is set so
that bending accuracy is easily stabilized.Approximately twice as
much as bottoming.Coining5 - 6×tThe purpose is to reduce inner
radius and reduce the amount of bite at the tip of the punch.iR
(inner radius)Bending MethodiR (inner
radius)FeaturesBottoming≒V/6Base values for maintaining safe and
stable accuracy, such as punch tip radius and
spring-back amount.Partial BendingWhen high accuracy is required,
use a bottoming type tool.CoiningCare must be taken when using a
bottoming die because iR increases and extra pressurization is
required. Processing and Manufacturing Packaging &
