How to choose bending machine?

        Let's talk about ordinary bending machine, that is, non NC bending machine, which is usually called ordinary bending machine. General machine tool manufacturers can produce all kinds of CNC bending machines, but whether the ordinary machine is good or not can best represent whether an enterprise has ingenuity.

       1. Enterprise scale, which directly affects after-sales, you can't expect a small enterprise with only a dozen employees to bring you immediate after-sales. A formal Enterprise and a healthy enterprise have a clear division of labor. Only in such an enterprise can you believe to bring you trustworthy products. How to measure the enterprise scale? Generally, I advise customers to visit the factory directly. The enterprise is informal, and it is clear at a glance whether the production is busy or not.

       2. The two points mentioned above are general and have no direct connection with the machine. Next, we want to talk about the quality of the machine. When you don't know a bending machine very well, how can we compare it? The first is the volume and weight of the machine. The main consumables used by a machine are steel. Machines with advantages in volume and weight will generally be lighter, stronger and better in quality. The second is the accuracy. To understand the accuracy of a machine, it is best to take your own machined parts to the factory machine, but generally there is no such condition. What affects the accuracy of the machine is the rear retaining material, vertical plate strength and die.

      3. The rear stopper is still driven by chain, so it can't be said to have precision. The beam is made of aluminum, which looks good, and the plate will be deformed after a few hits. There are also screw rods and guide rails. Now capable enterprises are equipped with ball screw rods and linear guide rails. The strength of the vertical plate is directly related to the thickness of the vertical plate. 4 now let's talk about the die. If the machine is compared to a soldier, the mold is a soldier's weapon. If the weapon is not good, you can't do others. And how to distinguish the quality of the mold? The first is the material. 42CrMo is a very good material for bending machine molds, and other materials such as cr6w2si are also good. If materials are used, ordinary users can't distinguish them without a period of time. In addition, general molds are high-frequency quenching, that is, the knife edge is heat treated, while good factories are full-body heat treated. Another feature of such molds is that there is a hole in the mold, which is an obvious feature of full-body heat treatment. The production cost of whole body heat treatment is much higher than that of knife edge heat treatment.

      Bending machine is divided into manual bending machine, hydraulic bending machine and NC bending machine. Bending machine is a common large-scale machine used for sheet bending. When selecting, it should be selected according to the use, working environment, degree of bending required, thickness of thin plate and other conditions.

How to correctly select accurate types is our primary knowledge: there are many types of bending machines, which can be divided into three categories and seven sub categories. Manual bending machines include folding machines, manual bending machines and electric manual bending machines. They are popular at home and abroad because of their small volume, low energy consumption, high work efficiency, large and fast production, many fields of use and convenient transportation.

     The hydraulic bending machine is divided into up moving type and down moving type. It adopts all steel welding structure, which has the characteristics of high strength and high hardness. The counter can display accurately, has high precision, high stability, complete overall structure, easy to use, and does not need high-tech personnel to operate.

     CNC bending machine is a new large-scale machine. Its high precision is favored by many people. It can adopt flexible operation mode. It can not only linkage between two machines to solve the problem of long plate processing, but also be operated and processed by a single machine, which can effectively improve the utilization rate, reduce energy consumption, and automatically adjust the compensation by the CNC system, which is convenient and accurate. According to the advantages and disadvantages of various bending machines, select the appropriate NC bending machine to maximize the benefits.
