How does a metal bending machine work?
The bending machine is a machine capable of bending thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressure plate. The base is composed of a seat shell, a coil and a cover plate, the coil is placed in the depression of the seat shell, and the top of the depression is covered with a cover plate. When in use, the wire is energized to the coil, and after energization, an attractive force is generated on the pressure plate, so as to realize the clamping of the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and it can also process workpieces with side walls, and the operation is also very simple.

Upper Tool Fast Clamp
·Upper tool clamping device is fast clamp
Multi-V Bottom Die Clamping(option)
·Multi-V bottom die with different openings
·Ball screw/liner guide are high precision
Metal Bending Machine Front Support
·Front support moves along linear guide, hand wheel adjust the height up and down
·Aluminium alloy material platform ,attractive appearance,and decrease scratch of workpicec.
Crowning Compensation for Worktable
· A convex wedge consists of a set of convex oblique wedges with a beveled surface. Each protruding wedge is designed by finite element analysis according to the deflection curve of the slide and worktable.
·The CNC controller system calculates the required compensation amount based on the load force. This force causes deflection and deformation of the vertical plates of the slide and table. And automatically control the relative movement of the convex wedge, so as to effectively compensate for the deflection deformation caused by the slider and the table riser, and obtain the ideal bending workpiece.
Quick Change Bottomm Die
·Adopt 2-v quick change clamping for bottom die
Lasersafe Safety Guard
·Lasersafe PSC-OHS safety guard, communication between CNC controller and safety control module
· Dual beam from protection are point below 4mm below the tip of upper tool,to protect operator`s fingers；three regions(front,middle and real) of leaser can be flexibly closed,ensure complex box bending processing ;mute point is 6mm,to realize efficient and safe production.
Mechanical Servo Bending Help
· When mark bending support plate can realize the function of turning over following.following angle and speed are calculated and controlled by CNC controller,move along linear guide left and right.
· Adjust the height up and down by hand, front and rear can also be adjust manually to suit for different bottom die openning
·Support platform can be brush or stainless steel tube ,according to workpiece size,two supports linkage movement or seperate movement can be chosed.
Slider adopts torsion shaft synchronous mechanism ,also install high-precision taper centering bearings (“K”model) at both ends of torsion shaft and install eccentric adjustment mechanism at the left end in order to make slider synchronous adjustment convenient and reliable.
Adopts Upper tool with tension compensating mechanism,upper tool port obtains a specific curves over the full length of the machine and deflection of worktable and slider improve bending accuracy of the tools when crowning through adjustment .
During the angle adjustment,the servo worm drives the movement of the mechanical stop in the cylinder,and the cylinder position value is displayed by the stroke counter.
The fixed place of the worktable and wallboard is equipped with an upper and lower adjustment mechanism ,which makes the adjustment convenient and reliable when the bending angle is slightly different.
The right side of the column is equipped with a remote pressure regulator, which makes the system pressure adjustment, convenient and reliable.
Adopts advanced integrated hydraulic system reduces the installation of pipelines and ensures a high degree of reliability and safety in the operation of the machine.
The speed of the slider movement can be realized. Rapid descent, slow bending, fast return back action, and fast down, slow down speed can be adjusted appropriately.
Electric control system
Eletrical component and material meet international standards,safe,reliable and long life.
The machine adopts 50HZ, 380V three-phase four-wire power supply.The motor of machine adopts three-phase 380V and the line lamp adopts single phase-220V.The control transformer adopts two-phase 380V.The output of the control transformer is used by the control loop, among which 24V is used for back gauge control and for electromagnetic reversing valves. 6V supply indicator, 24V supply other control components.
The electrical box of the machine is located on the right side of the machine and is equipped with a door opening and power-off device.The operate component of machine are all concentrated on the electrical box except the foot switch, and the function of each operating stacked element is marked by the image symbol above it.It can automatically cut off the power supply when opening the electric box door, and if it needs to be repaired live, it can be manually reset to pull out the micro switch lever.
Front and back gauge
Front bracket: It is Placed on the side of the worktable and secured by screws. It can be used as a support when bending wide and long sheets.
Back gauge: It adopts back gauge mechanism with ball screw and linear guide is driven by servo motor and a synchronous wheel timing belt. The high-precision positioning stop finger can be easily moved left and right on the double linear guide rail beam, and the workpiece is bent "as you like".

Application Scene of Metal Bending Machine
The bending machine is a common sheet metal equipment, and the high-efficiency CNC metal bending machine is an upgraded product of the common bending machine. For example, this is like the difference between the previous key mobile phones such as Nokia and the current Apple Android smartphones. The high-efficiency CNC metal bending machine has a wider range of applications.
1. In the decoration industry, the bending machine equipment can complete the production of stainless steel plates, doors and windows, and the decoration of some special places;
2. In the electrical and power industry, the plate can be cut into different sizes by using the shearing machine, and then reprocessed by the bending machine. Such as computer cases, electrical cabinets, refrigerator air conditioner casings, etc. did so;
3. In the kitchen and catering industry, various stainless steel kitchen utensils of various specifications are subjected to secondary processing such as welding and bending;
4. In the wind power communication industry, wind power poles, street light poles, communication tower poles, traffic light poles, traffic signal light poles, monitoring poles, etc. are curved, and they are all typical cases of bending machines;
5. In the automobile and shipbuilding industries, large-scale CNC hydraulic shearing machines are generally used to mainly complete the shearing work of the plates, and then perform secondary processing, such as welding, bending, etc.;
As small as the bending of non-ferrous metals, ferrous metal sheets, automobiles and ships, electrical appliances, decoration, kitchenware sheets, chassis cabinets, and elevator doors; as large as the aerospace field, metal CNC bending machines are playing an increasingly important role.
