1.Introduction

The press brake machine is a kind of machine capable of bending the thin plate. The structure 

mainly comprises a bracket, a worktable and a clamping plate, the worktable is arranged on the 

bracket, the workbench is composed of a base and a pressure plate, the base is connected with

 the clamping plate The base is composed of a seat shell, a coil and a cover plate. The coil is 

arranged in the depression of the seat shell, and the top of the depression is covered with a 

cover plate. The coil is energized by the conducting wire when in use, and the gravitation force 

is generated on the pressure plate after electrification, thereby achieving the clamping of the 

sheet between the pressure plate and the base. As a result of the use of electromagnetic force 

clamping, making the platen can be made of a variety of workpiece requirements, but also to 

have the workpiece sidewall processing, the operation is also very simple.

The whole structure of the hydraulic press brake:

Welded structure: the stress of the welded parts can be eliminated by vibration; so this

 forging press gives high accuracy.

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.

High accuracy,high efficiency,simple and convenient operation,good performance, favorable 

price and best service.

Hydraulic system: 

Adopt integrated hydraulic control system, more reliable 

Be installed at the top of the oil box, which can assure that the cylinder is always full of oil when

the slide is moving down at high speed 

Consist of motor, oil pump and valve groups 

Complete working cycle can be realized through the control of hydraulic valve. 

The working pressure at the right side of the wall board can be adjusted by the remote adjustment

valve

Protective fence and the safety interlock 

Protective fence and the safety interlocker to ensure the operation safety. Power supply switch

that is set in the electric box will be automatically turned off when the box's door is opened or

the fence is turned up. Protecting barrier with safety interlocker is mounted on the back of the

machine. Another, there are travel limit protection and foot pedestal mounted emergency off switch.

Synchro control system:

Slide syncho system: adopt steel torsion bar synchro system, simple in structure and high in

accuracy 

2 ends of slide has 2 synchro fork which make,The system uses upper die compensation to

improve the brake precision.

Adopt upper die compensation to improve the brake precision

Sectional Ram Clamp Bars:

Separate sectional clamping bars are supplied as standard equipment in order to securely fasten

short dies, as well as standard length tooling. Unique crown correcting device is standard.

Advance technology and procedures:

This metal machining tool is a kind of steel torsion bar synchro press brake. -Electronic control of

back gauges and ram stroke, data displayed and manual setting

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.

Quality assurance:

1.Company organizes the production as per ISO9001:2008 standard. From design control,

 process control, inspection control to delivery, installed and service, the whole process control. 

The running of quality system performs quality manual, procedure files, work instruction and

 related technical and management standard together with standard and regulation layout by 

company strictly. Quality system realizes whole screw and whole procedure control completely.

2. Quality assurance procedure for important out-source parts.
a. Mainly out-sourced parts: control system, cylinder, hydraulic components, motor, pump etc.
b. After evaluation, select qualified suppliers as business partners.
c. Purchasing according to plan, purchase contract, quality requirement, technical standard and 

inspection standard.

3.Receiving inspection on site either in supplier or our company with related technicians.
