This machine is high-efficiency and high-precision in bending sheet metal. Using different kinds of upper and lower dies can bend all kinds of work pieces. One slider travel makes a sheet bending and the complicated shape work piece may be achieved through bending many times. When fitted with relevant equipments, it can be used to punch holes.
5. Overall structure
5.1 Using UG (finite element) analysis, through computer aid design, with nice appearance.
5.2 The machine structure is welded with steel plate, with sufficient strength and rigidity. The hydraulic drive prevents the machine from serious overload operation accidents caused by the change of sheet thickness or bad choice of lower die cavity. Additionally, this machine is also featured by the steadiness of work, convenience of operation, and reliable safety.
5.3 The mechanic block is equipped in the oil cylinder to ensure the fixing accuracy when the slider travels to the bottom dead point and so as to assure the consistency of bending angle in bulking production.
5.4 Using German technology to eliminate internal stress.
5.5 Entire frame using striking grit to get rid of rust and spout anticorrosive paint.
6. Working slider structure
6.1 The machine is equipped with hydraulic electric control, freely adjustable slider travels and inching, semi-automatic, automatic operating criterion convenient for module trial and adjustment.
6.2 .Up-move type bending design,pair oil cylinders working simultaneously, balanced operation\convenient\and safety.
6.3 With function of keeping pressure and delay time on lower dead spot, to assure the accuracy of work pieces.
6.4 Under the national standard conditions, the accuracy of bending angle can up to ±45´.(Reference standard JB/T22572-1999.)
6.5 With function of slow decline, operator can control work pieces better.
7. Hydraulic system
7.1 Hydraulic system may realize quick decline, slow decline, working speed bending, quick return travel and sudden slider stop in the process of up and down etc.
7.2 Oil pump use axial plunger pump, can stand high pressure, and low noise.
7.3 Sealing rings from Japanese Wall Card, with good sealing performance, reliable working, and long life.
7.4 The machine can work continuously under rated burden, hydraulic system has no divulgence, continue and steady, high accuracy.
8. Electrical control system
8.1 Electric components and material are accord with international standard, safety and reliable, long life, and strong ant jamming capability.
8.2 Moving footpad attached.
8.3 Choosing high grade famous electrical control components.
8.4 The power of the machine is 3-phase and 4-line AC380V, control loop is AC220V.
8.5 Main power way of motor has short circuit\over load\lack phase protection.
8.6 Operation buttons equipped on machine button stage, electric switch\pilot lamp equipped in electric box.
8.7 Oil pump stop button as the total button of machine, when oil pump power off, whole machine stops working.
8.8 Inching control button and emergency stop button are installed on machine.
9 The synchronization of the slider travel of bending machine is mechanic synchronous unit in simple, stable and reliable structure with synchronous precision required by this machine. And generally, it can be used for long time while don't need to be repaired frequently.
10. Back stopper
The adjustment of back stopper is droving by 0.55KW motor, drove by lead screw after decelerated by gear. Press "+" and "-" to adjust the stopper plate forward and backward, (digital display dimension position) When electrical control can not attain the needing value, circle the hand-wheel to trim to got the require value.
11. Mould
1. A set of upper and lower die attached with machine.
2. Normally, the short moulds in sectional form are used to splice for desired length with high precision, fine interchangeability, and convenience for dismantling and installation. In particular, the connecting section to the upper die is equipped with wedge-shape regulating unit, which, as compensation, may raise the work precision of work pieces in full length.
3.The lower dies are processed in different V-gutters to make operators select conveniently, And it is equipped with lower die standing up structure, only need to put lifting roller chain on the slide lifting ear and lower die lifting ear, loose top formwork to raise slider to turn lower die then to select the location surface of V-gutter.
12. Standard accessories of machine
1. Front supporting 2 sets
2. Footpad switch 1unit
3. Bottom screw 4 pieces
4. Adjusting screw 4 pieces
