If it is a relatively short bending machine, it is best to be able to order some shims, so that qualified parts can be made better. This is a common sense, and it can also shorten time and increase production. In addition, if free bending is applied, in general, the bending radius at this time is 0.156 times, which is a common sense. It should be noted that usually, when the free bending mold is applied on a new bending machine, it will generally produce The projectile angle is less than 2 degrees.
Special attention should be paid to the problem of bending, which can directly affect the production problems. For example, if the bending requirement is greater than 1 or less than 1, then you should use a CNC bending machine. Also pay attention to the mold. Generally speaking, the deviation range of the conventional mold must be narrowed. It is generally about 0, 001 inches, and it cannot be too large. If it is a precision grinding mold, it is about 0.0004 inches. This is an introduction to the selection of bending machines. It can be said that it is more complicated. If you don't know anything about this aspect.
Wuxi Shenchong tells you how to choose and buy a suitable CNC bending machine, you need to consider the following factors:
①According to the material and thickness of the metal sheet to be processed and bent, calculate how many tons of cnc bending machine you need to buy. The ton here refers to the maximum pressure of the bending machine, not the weight of the CNC bending machine;
②The width of the blade face of the bending machine (determined according to the length of the plate), the depth of the throat and the distance between the columns;
③The choice of electro-hydraulic synchronous CNC bending machine or torsion shaft synchronous bending machine is also a problem to be considered. The electro-hydraulic synchronization type bending machine can be more intelligent and fully automated, but the price is higher and the torsion shaft synchronization type bending The machine is cheap;
④ There are many types of electro-hydraulic synchronous press brakes, which can be customized according to the requirements of the workpiece to be processed, such as the number of axes, compensation type, laser test, safety protection (laser protection or light curtain protection), etc.
