12M Street Light Pole Metal Tools Auto Hydraulic Bending Press Brake Machinery

 

Heavy steel pole press brake machine, double pump sheet bending machine

 

Applications:
the plates of different thickness are to be bended on this CNC press brake machine, V type bottom

dies of different sizes must be selected and if top and bottom dies of different shapes are used,

work-pieces of different shapes can be bended (Fig.2.1). The bending values can be

selected according to the Table 2.1 “ Bending Force Chart” and the operational oil pressure

(indicated by the pressure gage) is adjusted according to the values checked to ensure the

bending force required.
This machine has a higher productivity and is an ideal shaping equipment for plates widely

used in the manufacturing industries of aircraft, automobile, shipbuilding, electrical appliance,

machinery and light industry.

 

The  Structure Of The Machine:

 

Welded steel plate, the frame consists of right and left wall boards, working table,

oil box, slot steel and etc. The stress of the welded parts can be eliminated by vibration.

The machine enjoys high accuracy and high strength and can be transported easily.

 

Hydraulic System:
The servo electric CNC press brake machine is equiped with special hydraulic system from BOSCH company

Germany with reliable performance. Motor, pump and valves are mounted on the oil tank to improve integration

and reduce noise. In order to ensure that the ram rapid move down, an internal oil filling valve

in cylinder is adopted to increase the moving speed of ram and compact the machine structure.

 

Synchro Control System:

 

The slide synchro system adopts steel torsion bar synchro system with very simple

structure.but very high accuracy. 2 ends of slide has 2 sychnro fork which make the

slides movement is always parallel to the working table. And this will make the movement

effect balanced during operation. The system uses upper die compensation to improve

the brake precision.

CNC tandem electric press brake:

 

Advance Technology And Procedures:

 

The press brake machinery is a kind of steel torsion bar sychnro brake, which is the third generation of

brake. Electronic control of back gauge and ram stroke, data displayed and precision

control by man. Hydraulic power cell construction is convenient to install, which limit the

oil route and connector quantity to minimize integrated hydraulic valve block. Block route

and wide range of speed control, work steadily.Process of cylinder and sealing component:

Cylinder: no.45# steel treated, inner holes fine machined and extruded.

Valve rods: no.45# steel treated, nickel and phosphorous coated outside.

Dies:
Die is made from high carbon steel through processes of forging, heat treatment and milling.

The top die is composed of multiple short dies and it has advantages of high accuracy,

interchangeability and easy to assemble.
