(Summary description)In the whole process of sheet metal bending, CNC bending machine releases force on the plate, in addition, the plate will also cause a recoil on the machine, the recoil will promote the machine to cause deformation, and then harm the precision of the folded plate. Therefore, in order to improve the precision of sheet metal bending, mechanical equipment compensation and hydraulic compensation two kinds of CNC bending machine compensation methods should be born. When we buy CNC bending machine, in addition to considering the number of tons should be purchased (CNC bending machine sheet metal bending force) CNC bending machine, the total width of the wound surface, deep throat, vertical bar interval this element, CNC bending machine compensation should also be taken into account in it.

Information

In the whole process of sheet metal bending, CNC bending machine releases force on the plate, in addition, the plate will also cause a recoil on the machine, the recoil will promote the machine to cause deformation, and then harm the precision of the folded plate. Therefore, in order to improve the precision of sheet metal bending, mechanical equipment compensation and hydraulic compensation two kinds of CNC bending machine compensation methods should be born. When we buy CNC bending machine, in addition to considering the number of tons should be purchased (CNC bending machine sheet metal bending force) CNC bending machine, the total width of the wound surface, deep throat, vertical bar interval this element, CNC bending machine compensation should also be taken into account in it.

Because the two kinds of bending machine bending compensation is not the same as the actual operation of the workers, the precision of the goods is not the same, and it is particularly important for customers to grasp the compensation method that should be selected.

Hydraulic compensation is under the operating table is placed a number of small hydraulic cylinder, in the machine deformation, according to the number of small hydraulic cylinder release additional interaction force, compensation, and then reduce the damage of machine deformation on the folded plate. Numerical control machine tool hydraulic compensation is the first CNC machine tool in the machine, according to the length of the folded plate, thickness and other data information, to set the bending machine numerical control system software main parameters, in accordance with the machine computer operating system to calculate the required amount of compensation, the command will be transmitted to the compensation amplifier. The hydraulic compensation proportional solenoid valve receives the data signal from the compensation amplification instrument to operate the small hydraulic cylinder just below the operating platform to develop the protruding, reducing the deflection value of the plate independent variable.

As everyone knows, the amount of hydraulic compensation is harmed by a variety of factors, such as whether gear oil is leaked, loosening of the connecting head, etc., which is harmful to the amount of hydraulic compensation each time, thus causing each production and processing plate is not consistent, there is a difference. Hydraulic compensation system software is more complex, it is likely to appear oil leakage, seal ring loose and other problems. The advantages of hydraulic compensation depend on the fact that the machine is less prone to damage problems with the increase of use time, while the damage problems of mechanical equipment compensation will occur.

Compared with the mechanical equipment compensation, the choice of hydraulic compensation machine is simple in actual operation, the provisions of the workers are not high, you can fold out a high precision product workpiece. Moreover, the selection of hydraulic compensation system software of the machine, can ensure that the lower die and plate sufficient contact, to ensure that the plate is not allowed to produce deviation. From the perspective of machine durability and practical operation simplicity, it is good to choose hydraulic compensation machine.

Hydraulic compensation is to use small hydraulic cylinder to carry out compensation, mechanical equipment compensation is to use inclined wedge to carry out compensation to the work table. The inclined wedge can be divided into a single inclined wedge and a number of inclined wedge. The mechanical equipment compensation composed of multiple oblique wedges has more compensation points, more than the general hydraulic compensation of 3 compensation points, there will be no compensation blind spot, the folded product workpiece high precision, each production and processing plate difference is small, suitable for large quantities of quantitative production and manufacturing. The mechanical equipment compensation system software relative to the hydraulic compensation system software is simpler, less prone to oil leakage and other situations, low repair rate and environmental protection. However, the mechanical equipment compensation will be accompanied by the change of use time, the inclined wedge will appear damage, and then harm the actual effect of compensation. The actual operation of mechanical equipment compensation is high. If the sheet metal must be bent several times for the same product workpiece, the workers must carry out immediate adjustment, even if the workers are more experienced, it will cause unexpected deviations. If the folded product workpiece does not have several sheet metal bending, the worker is more technical, from the product workpiece accuracy into consideration, mechanical equipment can be selected compensation, but in the specific production and manufacturing, the worker cost of high technology is also high, so the comprehensive consideration.
