Teach you how to choose a suitable for their own CNC bending machine
In China's automobile, aircraft manufacturing, light industry, shipbuilding, container, elevator, railway vehicles and other industries, there is a CNC machine tool is widely used, and the ordinary machine tool is different, it is often large, and has a strong "bite force", I believe that the netizens have guessed its name, it is CNC bending machine.
Most users in the choice of CNC bending machine, the main consideration is the material brand, as well as the maximum processing length, and thickness, which is relatively easy to understand.Of course, this refers to the user's own processing of goods, can be accurate choice, only in this way can reduce the output of the cost, you know, for the bending machine selection is appropriate, can directly related to the cost of the problem.
Generally speaking, it depends on what kind of parts the user wants to produce, and he or she can make a choice on the condition of determining his or her own maximum bending machine, without having to choose those unwanted tonnage.In addition, in order to choose the lowest tonnage specification, is able to choose greater than the thickness of its own production parts, in this case, to ensure that the machine in a certain situation, do not do the load work, ensure the service life of the bending machine.Of course, if the tonnage is too large, it will affect the accuracy of the parts, but if the size is slightly larger, it will not affect this point.
What the user needs to do is to carefully consider the material grade and the maximum machining thickness and length.If the majority of the work is on low-carbon steel with a gauge of 16 and a maximum length of 10 feet, the free bending force need not be greater than 50 tons.However, if you do a lot of bottom die forming, you might want to consider a 150 ton machine tool.Assume that the thickest material is 1/4 inch, 10 feet free bending requires 165 tons, and bottom die bending (corrected bending) requires at least 600 tons.If most of the workpieces are 5 feet or less, the tonnage is roughly halved, greatly reducing the cost of acquisition.The length of the parts is important in sizing up the new machine.
Of course, the choice of bending machine is mainly based on the user's own situation, which is a certain, but also a direct factor to reduce production costs.Bending machine can also be used for the workpiece dead side, first the workpiece bending to 30 degrees, and then use a flat knife to the workpiece dead, but generally available ordinary punch press dead side as far as possible not arranged to the bending machine, because the punch press dead side effect is relatively better.When arranging process, a lot of time to consider whether good bending, bending, whether the problem that because the bending is a very important process, the bending is good operation directly affect the bending quality guarantee, but a lot of time appear quality problems are come from bending size is no good control, so in the process of design also want to pay special attention to the problem of bending, this is related to the stability of product quality when mass production.
In the actual bending process will also encounter a variety of problems, a lot of time to consider the impact of bending on other processes, a lot of time to specific problems specific analysis, appropriate arrangement of the process.At the same time, in some special needs, the supplier will also make special bending knife, but if the shape of the tool is more strange or the greater the bending, will inevitably affect the rigidity of the tool, shorten the tool life.At present, the development of CNC bending machine is also facing many tests, in the numerical control system, CAD and CAPP applications and flexibility is developing rapidly, but China's CNC bending machine industry to continue to grow, there is a long way to go.
