In terms of electric drive and control, the new IndraMotionMLC helps users achieve double productivity. It features an open IndraLogic PLC that adapts to IEe6ll31-3 and enables real-time motion control of up to 16 axes. The open interface and different specifications give users more choices. In terms of hydraulics, with the introduction of 132 hydraulic and electric spindle motion control solutions, Rexroth has written a new chapter in industrial automation. The CST3, which was first exhibited, is a new series of hydraulic cylinders that are outstanding in closed-loop control and positioning tasks, especially in the complete contactless positioning measurement system. It is a modular structure that communicates with higher-level control systems via Profibu:DP or Ethernet, and also communicates with the field layer via CANbus.
In terms of linear motion control and integration technology, the ID recognition system has attracted the attention of many viewers. It consists of a mobile data tag and a read/write head, which is mainly used in the company's Tsl, Ts4plusvarioFlow transmission chain. The affordable eLNE product family continues to expand, allowing the application of linear motion control to expand. On the pneumatic side, Rexroth's new pressure regulators bring a new concept of pressure adjustment, which can be rotated to change position to automatically compensate for moving tools or tool carriers. Users save time and money. There are also SFI sensors that are tightly attached to the cylinders and can be remotely adjusted as needed, creating new standards in the field.
The HAWE hydraulic field is particularly remarkable in the development of turnkey systems, product compactness and 01-submerged units. Intelligent valve technology, low-noise pumps, and cooling devices are more powerful for standard single-system solutions, and are sure to be favored by users. The hydraulic spindles used in machine tools have been trying to revive, but the fact is that they are running counter to each other. All-electric plastic equipment is gradually losing its territory and giving way to equipment that combines multiple technologies. The hydraulic system can be precisely controlled, but it is ideal for achieving some of the secondary functions of the machine, such as main traction, loading and injection molding. HAwE not only provides standard products for complex applications, but also introduces newer products, mainly focusing on proportional technology applied to construction machinery. Mr. Karl Haeusgen, CEO of HAWE Hydraulics, said that in order to achieve sustained growth in this area, investing heavily in export markets is the only way out. Presumably the Chinese market must be within its bounds.
pM-Bearings Inc. has released its new RTUL series of ultra-precision linear guides. These sliding members are made of high-quality carbon fiber and have high strength and low momentum in terms of motion. This component is said to support a variety of industry standard sizes. These linear parts are easy to install, the upper part has a standard threaded hole, and the lower part has a countersunk threaded hole. All reference faces and edges are finely ground. Due to its low frictional resistance, high precision and smooth linear motion, this sliding member is suitable for precision instruments such as fiber positioning systems. The company has introduced the latest developments: the LK series linear couplers for linear drives and linear path measurement systems. The newly developed coupling has no moving parts relative to the familiar swing bearing. According to reports, the tension and pressure are completely transmitted by the rear seat, and there is no lateral force. The manufacturer pointed out that modern linear potentiometers and linear drives can only achieve positioning accuracy of up to a thousandth of a millimeter when lateral forces are eliminated. This series can be used for accelerations up to a maximum of 3, with a pull and pressure of up to 20 (X)N and is extremely durable. It is definitely a topic for MDA20OS to monitor and monitor the state-of-the-art monitoring products and new ideas.
Hexagon Bolt refers to the fastener composed of head and screw. According to the material, the bolt can be divided into iron bolt and stainless steel bolt, namely hexagon head bolt (partial thread) - C grade and hexagon head bolt (full thread) - C grade.
1. According to the stress mode of the connection, there are common and reamed holes. The bolts used for reaming holes should match the size of the holes and be used when subjected to transverse force
2. According to the head shape, there are hexagon head, round head, square head, countersunk head and so on. Generally, countersunk head is used in the place where the surface is smooth and no protrusion is required after connection, because countersunk head can be screwed into parts. Round head can also be screwed into parts. The tightening force of square head can be larger, but the size is large. Hexagon head is the most commonly used.
In addition, in order to meet the needs of locking after installation, there are holes in the head and in the rod, which can prevent the bolts from loosening when they are subject to vibration.
Some bolts have no thread of smooth rod to do thin, called thin waist bolt. This kind of bolt is conducive to variable force connection.
There are special high strength bolts on the steel structure. The head will be bigger. The size will also change.
In addition, there are special uses: T-shaped slot bolts, most of which are used in machine tool fixtures, with special shape, and both sides of the head need to be cut off. Anchor bolts are used to connect the machine and the ground, and there are many shapes, such as U-shaped bolts, and so on.
There are also special studs for welding, one with thread and the other without thread, which can be welded on the parts, and the other side can directly screw the nut.
