Is it necessary to choose a famous brand for CNC bending machine?

It is recommended to choose a cost-effective CNC shearing machine bending machine, of course, for the shearing machine bending machine is not very familiar with the premise of the famous brand of CNC bending machine shearing machine is more worry-free, but it will be high.

This depends on the requirements of the things you process, the precision is high, the brand is relatively better, basically can meet the requirements, the requirements are not very high, generally on the line, after all, the brand is relatively large.

The press brake is the same as the shearing machine, and there are three kinds of manuals.

Among them, the manual bending machine is divided into moving. On the hydraulic press brake, there are two types: upward and downward moving. The coordinate axis of the bending machine has been developed from a single axis to 12 axes, which can be automatically controlled by the numerical control system to control the running depth of the slider, the left and right tilt adjustment of the slider, the front and rear adjustment of the rear material stopper, the left and right adjustment, the pressure tonnage adjustment and the adjustment of the working speed of the slider approaching and so on.

CNC bending machines are generally made of all-steel welded layout, which has sufficient strength and rigidity. Hydraulic upper transmission, the cylinders at both ends of the bending machine are placed on the slider to directly drive the sliding operation. The slider synchronization organization selects the torsion shaft to force the synchronization.

The mechanical block layout is selected, which is stable and reliable. The slider stroke is motorized and quickly adjusted, manual, and the counter is displayed. The wedge-type deflection compensation organization is used to ensure high bending accuracy.

There are three layout types commonly used in CNC bending machines:

1. Upward moving CNC bending machine, that is, the downward movement of the slider strand punch. In order to ensure that when the slider is operated and returned, the slider will not be skewed relative to the working table due to the difference between the eccentric load and the resistance of the left and right cylinder pipelines, and then affect the forming quality of the workpiece, and the slider motion synchronous control system is generally equipped.

2. Downward moving CNC bending machine, that is, the slider is installed in the lower part of the machine tool, and the strand dies move upward. The operating oil cylinder is placed in the center of the slider, and the tonnal force is a single cylinder when the tonnal force is small, and the tonnal force is three cylinders when the nominal force is large. Because the working cylinder is concentrated in the middle of the slider, the deformation of the slider and the beam is common, and the gap between the convex and concave molds is uniform in the full length of the slider, so the bending accuracy of the workpiece is higher.

3. The three-point bending CNC bending machine is operated according to the operating principle of the three-point bending method mentioned above, and the strength of the three-point bending machine lies in the high bending accuracy, wide process use, and has the function of four-sided forming machine. However, the layout of the bending machine is messy, the cost is high, and the current ** is equivalent to twice that of the upward CNC bending machine.

The common types of bending machines are the same as shearing machines, and there are three kinds of manual and hydraulic press numerical control. Among them, manual bending machines are divided into mechanical and electric. On the hydraulic press brake, there are two types: upward and downward moving.

The bending machine is to use the equipped mold (general or special mold) to bend the metal sheet into various geometric cross-sectional shapes of the workpiece in the cold state, the bending machine generally adopts the special numerical control system of the bending machine, the coordinate axis of the bending machine has been developed from a single axis to 12 axes, and the numerical control system can automatically realize the running depth control of the slider, the left and right tilt adjustment of the slider, the front and rear adjustment of the rear baffle, the left and right adjustment, the pressure tonnage adjustment and the adjustment of the working speed of the slider approaching and so on.

Small press brakes: foot pedal, manual.

Hydraulic press brake.

The installation of a CNC system is a CNC bending machine.

There are also high-end electro-hydraulic servo press brakes.

What about the price in mind? High-end electro-hydraulic servo press brakes can be considered Hubei Huangshi, Jiangsu Shanli, Jiangsu Jinfangyuan and Guangdong Lifeng. The mid-end ordinary CNC is recommended to go to the field, adding a system only costs a few thousand dollars, but the accessories to keep up with the system function are worth tens of thousands.

In China's automobile, aircraft manufacturing, light industry, shipbuilding, containers, elevators, railway vehicles and other industries, there is a CNC machine tool is widely used, unlike ordinary machine tools, it is often larger, and has a strong "bite force", I believe that netizens have guessed its name, it is CNC bending machine. Most users choose a CNC press brake when they choose.

The main thing is to consider the material grade, as well as the maximum processing length, as well as the thickness, which is relatively easy to understand. Of course, this aspect refers to the situation that the user processes the goods themselves, and can make accurate choices, only in this way can the output of the cost be reduced, and it is important to know that the selection of the press brake is appropriate or not.

It can be directly related to the cost of the issue. Generally speaking, it is to look at what type of part the user wants to produce, and choose to determine the maximum conditions of the press brake, rather than choosing the tons that are not needed. In addition, in order to select the minimum tonnage specification, it is possible to select a thickness that is larger than the thickness of the part made by itself.

It can ensure that the machine does not work under certain circumstances and ensures the service life of the bending machine. Of course, if the tonnage is too large, it will affect the accuracy of the part, but if it is slightly larger, it will not affect this. What the user needs to do is to carefully consider the material grade as well as the maximum processing thickness and length.

If most of the work is mild steel with a thickness of 16gauge and a maximum length of 10 feet, then the free bending force does not have to be greater than 50 tons. However, if you are engaged in a large number of bottomed die molding, you may want to consider a 150-tonnage machine tool. Assuming that the thickest material is 1 4 inches, 10 feet of free bending requires 165 tons.

And the bending (corrected bending) of the bottom die requires at least 600 tons. If most of the workpieces are 5 feet or less, the tonnage is almost halved, which greatly reduces the cost of ownership. Part length is quite important in determining the specifications of a new machine.

The CNC bending machine is a workpiece that uses the equipped mold (general or special mold) to bend the metal sheet in the cold state into various geometric cross-sectional shapes. It is a sheet metal forming machine designed for cold-rolled sheet metal processing, which is widely used in sheet metal bending processing in automobile, aircraft manufacturing, light industry, shipbuilding, container, elevator, railway vehicle and other industries.

The operation method of the CNC bending machine:

1. First of all, turn on the power supply, turn on the switch on the control panel, and then start the oil pump, so that you can hear the rotation sound of the oil pump, but the machine does not perform the action at this time.

2. Stroke adjustment, you must pay attention to adjusting the stroke when using, and you must test it before bending. When the upper mold goes down to the bottom, it must ensure that there is a gap of plate thickness, otherwise it will cause damage to the mold machine, and the adjustment of the stroke is also electric and quick adjustment.

3. For the selection of bending notches, it is generally necessary to choose a notch that is 8 times the width of the plate thickness. If you bend a sheet of 4mm, you need to choose a notch of about 32.

4. The adjustment of the backgauge material generally has electric quick adjustment and manual fine-tuning, and the method is the same as that of the shearing machine.

5. Step on the foot switch to start bending, the CNC bending machine mold is different from the shearing machine, it can be released at any time, and the foot will stop when you release it, and continue to go down when you step on it.

The CNC bending machine is to control the bending angle by pressing the strip sheet in the upper die (bending depth), or to press the workpiece into a workpiece at the same angle as the mold.

CNC bending machine conventional bending sequence:

First short side and then long side: Generally speaking, when there are bends on all four sides, folding the short side first and then folding the long side is conducive to the processing of the workpiece and the assembly of the bending mold;

First the periphery and then the middle: under normal circumstances, it is generally folded from the periphery of the workpiece to the center of the workpiece;

First part and then whole: if there are some structures inside or outside the workpiece that are different from other bending, these structures are generally bent first and then other parts are folded; Considering the interference, arrange the bending sequence reasonably: the bending sequence is not immutable, and the processing sequence should be appropriately adjusted according to the shape of the bending or the obstacles on the workpiece.

Precautions for CNC bending machines

The operation of the CNC bending machine should conform to the instruction manual, safety operation procedures and work instructions of the bending machine, and do a good job of various protective work to ensure personal safety and equipment safety When bending the operation, we should always pay attention to personal safety. It should be adjusted directly to the back of the device.

When processing parts, the human body should be outside the range of activity of the parts to avoid the parts scraping the human body; During operation, the human body should stand firmly, and the balance of the body should not be affected by the movement of the workpiece; The removed tool cannot be placed on the press brake, nor can it be leaned on the bending to avoid the knife falling and injuring the human body.

To put it simply, it is a press brake that can digitally control the downward stroke and pressure of the press brake head. For example, it can be programmed, the first step is to press down the stroke of 5cm, and the pressure is 10 tons; The second step is 10cm and the pressure is 20 tons. The advantage of this is that the bending angle can be accurately controlled with the mold.
