As we all know, small size, high speed and high precision are one of the unremitting pursuits of machine tool manufacturers at home and abroad in recent years, and one of the conditions for measuring the comprehensive performance of machine tools.
Small size
The small size means saving valuable floor and space, and the smaller the device, the more energy-efficient it is when it meets the same function. Small size has many advantages, and developed countries have noticed this as early as many years ago, and attach great importance to the development of small-volume products. With the development of the national economy, this will be more and more important in China.
In the case of meeting the same electrical requirements, the igus cable is smaller and lighter than other similar cables. The igus cable has a very good bending performance with a minimum bend radius of 3.5 to 5 times the cable outer diameter.
Practice has proved that the specifications of the towline required for the use of the igus cable can be reduced accordingly. Under the same bearing capacity, the dimensions of the igus towline are optimized to reduce the assembly space by about 10%. If all the igus drag chains and cables are used, the external dimensions of the drag chain system can be reduced by about 20~50%.
High speed and high acceleration
Speed ​​and efficiency have always been the unremitting pursuit of all machine tool manufacturers.
All igus products are rigorously tested in the laboratory. The towline runs in suspension, and the service life is usually more than 10 million times at =10m/s and a=10m/sz. In the case of such high speed and high acceleration, the conventional drag chain is difficult to achieve such a service life. In the laboratory of the German factory, the igus towline still works well in the case of a=78.4g. The high-speed operation of the machine tool also places demands on the flexibility of the mobile power supply cable. In the case of high speed and high frequency, the outer cable will wear out of the outer sheath, the outer sheath is serpentine, the core is broken, and the transmission rate is lowered. Igus adopts special core wire making process according to the specific use of the towline, adopts inner and outer double sheath, special outer sheath strong extrusion process, and is suitable for the high wear resistance, oil resistance and harsh environment protection used in the drag chain. Set of materials.
The igus cable usually allows acceleration a = 50 m / s 2 , floating use v = 10 m / s, long stroke taxi using v = 5 m / s. The igus cable is suspended for use under sample-guided installation conditions and typically has a service life of no less than 10 million reciprocations. All igus data on the life of the chain and cable are from the laboratory. The long life of the towline and cable is an important guarantee for the high reliability of the equipment.
For the vibration of high-precision machine tools, even the slight vibrations are the consideration of perfect machine tool experts. We know that the conventional drag chain is composed of one section. Generally, the larger the pitch, the greater the noise and vibration generated by the drag chain at the same speed, and another cause of noise and vibration. It is the vibration and noise generated by the two chain inter-chain stoppers in a short time.
E6 new drag chain
As early as a few years ago, igus reduced the vibration and noise by improving the stopper and adding auxiliary noise-reducing components. Recently, igus has successfully launched the E6 series of towline chains. This type of towline adopts a special structure (Fig. 2), which eliminates the hole pin design of the traditional towline and adopts a new limit type limit, which is generated by the elastic element eliminating the stopper contact. The vibration and sound, the smaller pitch and the optimized curved surface design of the tow side panels minimize the sound when the links are in contact with the support surface. All of these designs make the igus E6 towline run smoother, minimizing vibration and noise, and eliminating wear between traditional drag chain pins.
Since the launch of the igus E6 series towline, it has been widely welcomed by foreign machine tool manufacturers. Since the beginning of 2004, we have started to promote this type of towline in China.
With the development of production technology, various machine tool manufacturers are increasingly demanding mobile power supply. Igus has launched the assembly chain ReadyChain in Europe, which is welcomed by more and more manufacturers. After the customer makes a specific need, the igus engineer will quickly give the system design. After confirmation by both parties, igus is supplied to the customer with a towline system that is fully assembled with the towline, cable and other required components. This system is the assembly drag chain. It develops designs based on the specific needs of the customer. The customer can arbitrarily determine the size of the order, determine the degree of integration, and choose the length of the trip.
In the actual application process, the economic and technical advantages of the assembly towline are fully confirmed. The assembly towline fully meets the customer's needs, enhancing overall performance and significantly reducing the failure rate. The cost of personnel, procurement and warehousing is greatly reduced. If many separate components are combined, only one purchase order code is required. Significant savings in tooling, time and assembly area costs. All in all, many processes are omitted. These advantages significantly increase cash flow and shorten project execution cycles.
Previously, the project on flexible energy supply systems and pre-assembled cable plugs was focused on cables and tubing in towline and towline, as well as plug connectors and other add-ons. In addition to these core components, igus now offers steel components, fixed tubes and a variety of bolting methods.
In addition, the scope of supply also includes components that are compatible with igus products, such as sensor/drive distribution boxes, forward distributors, hydraulic component splits and linear guide systems. The complete system to be installed is shipped directly to the machine factory on an igus-specific transport rack. To install the complete system to be installed on the machine, all you have to do is loosen the two bolts. After connecting the contact surfaces and installing the cables and tubing, the machine is ready for operation. Plug in the power and turn it on, it's that simple.
All in all, we clearly see that with the continuous development of production technology, features that were previously considered not important are gaining more and more attention.
The rapid development of the domestic machine tool industry in recent years is obvious to all. We are delighted to see that the products of domestic machine tool manufacturers have focused on the development of basic functions and have begun to notice the humanized design and details of the equipment. Excellent machine tool components not only improve the appearance of the machine, but also improve the performance of the machine from the details in the eyes of the designer who is pursuing perfection. The following is an analysis of the importance of the drag chain and the towline cable on the machine tool from the perspective of mobile power supply.
