8.Structure Character

front support

Be equipped with the standard simple front support. It also can be supplied with more or special front support as customers’ special requirement.

Mechanical crowning device to be equipped on the work table under the lower die to help to improve the bending accuracy

crowning

Two layers of independent wedges and these two independent wedges can be moved relatively to create a correction curves, it will help to ensure the ram and the table are parallel during bending.

Mechanical-hydraulic synchronization system

--Mechanical-hydraulic synchronization system, which use a torsion bar to ensure the parallelism between beams, it’s a efficient and accurate mechanical synchronization system.; It’s a simple structure, but can avoid the one-side loading.

--Main cylinder

The cylinder body is manufactured from solid material , the piston is hardened and shows a superfine finishing.

Extremely reliable and precise hydraulic block used for the regulating circuit.

Electrical components

The electrical control system is a switch cabinet on the right side frame. Main of the electrical components are SIMENS and Telemecanique, which have overloading protection in accordance with the ISO standard.

Control panel

Control panel, all of the function buttons are with symbol, easy to be recognized and convenience to operate

Motorized back gauge, LED display, back gauge with manual adjustment, vertical adjustment by manual, back gauge stopping finger can be moved transverse manual.

heat-treated punching tool

Different types of punching tool and lower die can be supplied,

8.Operating Character

During working, this machine has three types speed,

--when the beam move from the top dead center, the speed is fast

--when the beam touch the bottom dead center, the speed changed, and it’s going to be the bending speed

--when finish the bending, the beam return to the top dead center fast.

The ram stroke can be adjusted according different thickness and V-channel width.

9. Main components

--Integrated hydraulic system, HUADE valve, REXROTH size

--Digital readout, Korea

--Crescent gear pump

--SIMENS BEIDE main motor

--PARKER seals

--AUTONICS readout and rotary encoder

--SIEMENS/ SCHNEIDERmain electric parts

10. Accessory

--Front extensive arm, 4 pieces

--Anchor bolt, 4 pieces

--Nut, some pieces

--Washer, some pieces

--Oil gun, 1 piece

--Foot pedal

11. Bending force calculating

1.42 X L X σ b Xt²

F= --------------------------------------

1000 V

F: bending pressure/ force (KN)

t: plate thickness (mm)

L: bending length (mm)

V: width of V-channel (mm) (normally the width is about 8 X plate thickness)

σ b: tensile strength ( N/mm²)

1kgf≈ 10 N 1MPa≈10bar 1tf≈ 10000 N= 10 KN

11.Warrenty: one year

12.Payment:30% down payment and 70% paid after receiving the copy of the documents

13.Delivery:50 days after receiving the 30% down payment

14.Loading: plastic cover coat, through containers

15.Technique support and service:support twice operating training, first one is at my factory during the processing time, second one at the buyer’s factory during the re-installation/testing period. We will send our engineers go to buyer’s factory help to re-install this machine if customer required, and the customer need to pay for their flight tickets( go and back), room and board, local travel cost
