Why is the servo CNC pipe bending machine so popular for bending chairs?

Comparing our CNC pipe bending machine and hydraulic pipe bending machine in the process of bending seat frames, especially office chair frames, the difference is significant. Using our hydraulic pipe bending machine to measure bending length, feed size, and conversion angles is very troublesome. It requires multiple operations. Forming the pipe in one go is basically impossible. When bending such pipes, two people are needed to operate the equipment simultaneously. This long time not only wastes manpower but also introduces errors in the bending angles, leading to asymmetry in the seat angles or different dimensions on both ends. This results in mismatching.

Compared to the price of a hydraulic pipe bending machine, the price of a CNC pipe bending machine is much higher. However, for the furniture industry, especially for bending machines used in seating and other pipes, CNC equipment is still very advantageous. The price of CNC equipment is higher than that of hydraulic pipe bending machines.

But why are hydraulic pipe bending machines still so popular in the furniture industry? In fact, it is not difficult to understand. For small companies, the price of a CNC pipe bending machine can exceed hundreds of thousands, even tens of millions. After all, the price of a CNC pipe bending machine is too high.

Roughly speaking, it is certainly not as flexible as a hydraulic pipe bending machine. Due to the low cost, it greatly reduces the difficulty of after-sales maintenance and also has many advantages in terms of maintenance costs. For large-diameter pipe bending, a hydraulic pipe bending machine can be purchased separately. If so, the cost of a CNC pipe bending machine will make the company consider a comparison of cost and output. The servo motor of the pipe bending machine has faults. Pipe bending machines, heat shrink machines, and pipe cutting machines, the positioning accuracy of CNC pipe bending machines has been tested by domestic mathematical statistics, but the promotional methods of some companies differ.

In addition, when choosing CNC machine tools, it should be said that they meet the unit workpiece processing accuracy requirements. Generally, if the conventional level is sufficient, do not enter the accuracy level. Otherwise, the cost will increase significantly, and investment will also increase.

There are many types of pipe bending machines, such as hydraulic type, automatic servo motor type, gear structure type, etc. However, for pipe bending machine molds, they are the same. The size of the bending pipe radius determines the size of the wheel mold, and from the size of the wheel mold to the size of the auxiliary pushing device.

The clamping mold and the upper mold are determined by the diameter of the pipe. According to the technical requirements of pipe bending, if the bending radius is too small to reach the normal mode, wrinkling, breaking, deformation, and other phenomena will occur.

However, bending pipes is not simple, because if the bending radius of the mold is too small, it depends on the material and wall thickness of the pipe. Wrinkles and fractures cannot be avoided.

No matter how difficult the pipe is, as long as the mold design is reasonable, the structure of the pipe bending machine equipment can reasonably bend it.

The reason there are so many pipe bending machine equipment is that there are many defects in the molds. Therefore, we use automatic pipe bending machines, fully automatic CNC pipe bending machines, or rounding machines, CNC pipe bending machines, and other machines to make up for the defects in the molds.

In recent years, due to the impact of the economic development environment, the main economic operation indicators of China's machine tool industry have declined, new orders have significantly decreased, production and sales have significantly declined, capital occupation has significantly increased, the number of idle manufacturing resources, and the contradiction between supply and demand have become increasingly prominent. The industry has become more seriously unbalanced in capacity structure, and the already severe homogenous market competition has further intensified. The overall level of the host machine is far behind that of foreign countries.

Although the proportion of domestically produced CNC machine tools is increasing, there is still a significant gap between the host machine and the advanced foreign levels in core R&D capabilities, product design levels, accuracy, quality, and performance. The mid-to-high-end CNC machine tools urgently needed in the market, such as machining centers, CNC lathes, precision grinders, and special processing machine tools, are all imported. Few companies can provide users with complete service and lineup services, and they lack the ability to provide complete solutions or execute more complex EPC projects; product quality stability and reliability are poor.
