The Development Direction of Wire Drawing Machines in China


According to the characteristics of different metal products, Chinese wire drawing machines are developing in the following directions.


(1) For the production of large-scale low-relaxation prestressed steel wire, steel strand wire, large-scale high-strength and high-toughness mining steel wire and large-scale special-shaped steel wire, the tuning roller linear wire drawing machine will be widely used.


Such as 700, 750, 900 wire drawing machines, etc. Although this type of wire drawing machine has a large investment and requires a high level of operation and maintenance, in order to greatly improve the quality and output of various large-size steel wires, this type of wire drawing machine has the advantages that other wire drawing machines cannot replace. Play an increasingly important role in the production of products.


(2) For the ordinary medium and small-sized steel wires that account for the largest proportion of the finished product, especially the production of steel wires that use medium 6 5 medium 5 5 heavy wire rods as raw materials, the Japanese-style combined wire drawing machine will last a long time Inside, it occupies the leading position in the wire drawing machine for the production of such products.


Since Japan successfully applied the AC frequency conversion speed control system to the wire drawing machine equipment in the 1970s, the application of this technology in production equipment has developed rapidly, and the production equipment manufacturers in Western Europe have also adopted this technology; such as KOCH has applied this technology on the tuning roller linear wire drawing machine and achieved success. China also has a successful example of applying this technology to a looper wire drawing machine.


For the tuning roller linear wire drawing machine and looper wire drawing machine driven by DC, the AC frequency conversion speed regulation system can greatly simplify the electric control system of the wire drawing machine, making operation and maintenance easy.


This technology is also important for the pulley wire drawing machine, which can make the pulley wire drawing machine wider and more adaptable, while also minimizing the number of twists of the wire during the drawing process, thus compensating for some disadvantages of the pulley type wire drawing machine improves the quality of the steel wire.


At present, the domestic AC frequency conversion speed regulation system has not yet been localized for key components, resulting in a relatively high price for the system. But this is only temporary. The great vitality of the AC variable frequency speed control system lies in its ability to greatly reduce the complexity and manufacturing cost of the electrical system.


With the development of China's electrical industry and the localization of system components, it will be more and more widely used in Chinese wire drawing machines. the


(3) For the production of various steel wires with small specifications, the wet wire drawing machine will be further updated, and the 21/250 high-speed wet wire drawing machine with bidirectional drawing ability will occupy a dominant position, such as the Italian TB4 and the German KOCH-21/250 And other typical representative models.


In addition, through the exploration and summary of various product manufacturers, large-scale water tank wire drawing machines such as 9/450, 9/550, and other models and pulley-water tank combination wire drawing machines will gradually increase their role in water tank wire drawing machines in future development. Proportion. the


According to the above analysis, considering the proportion of various wire drawing machines in actual production, we think that the most urgent task in the design of Chinese wire drawing machines is to develop 550 series combined wire drawing machines and various wire drawing machines controlled by frequency conversion technology as soon as possible. 

To replace the ordinary pulley-type wire drawing machine currently used by most metal product manufacturers in China, so that the equipment level and product quality of China's metal product industry can catch up with the international advanced level as soon as possible.

I am a Wire Drawing Machine, and I need Maintenance I am a wire drawing machine, which is composed of bearings, motors, yarn guide rods, forced beam splitters, controllers, etc. From the day I was assembled, passed the inspection, and left the factory, my mission and meaning have been doomed. Contribute to producing good fiberglass. When I came to the new factory, after being installed and debugged, I started my work. The two machine heads exchanged with each other, and the glass fiber was drawn out from the platinum bushing by winding and pulling.  The bundle comb is wound on the machine head covered with the paper tube, and the cycle is repeated until the set time is up, the machine head is changed, and the traction is continued. Throughout the year, from winter to spring, I work like time, non-stop operation, although it is hard work, hard work, day and night, but I will also get sick, the long-term wear and tear of parts, let me The sound of "creak" and "kuang kuang...

What is a Wire Drawing Machine? Wire drawing machine is a widely used mechanical equipment in industrial applications, widely used in machinery manufacturing, metal processing, petrochemical, plastics, bamboo, wood products, wire and cable, and other industries. Types of Wire Drawing Machine Wire drawing machines can be divided into metal wire drawing machines according to their uses (for the production and preprocessing of metal products such as standard parts); Plastic wire drawing machine (used in the plastic products industry to use polyester, nylon, polyethylene, polypropylene, polyester chips, etc. as raw materials to produce various hollow, solid round wires or flat wires for deep processing of special equipment); Bamboo wood wire drawing machine (special equipment for making chopsticks, toothpicks, barbecue sticks, etc. in the bamboo and wood products industry to pull out bamboo wire and wood wire for reprocessing), etc.

Features of Tungsten Carbide Wire Drawing Die

图片
Features of Tungsten Carbide Wire Drawing Die Although the materials of the drawing die can be different, among different drawing dies, the cemented carbide drawing dies to become the highlight. Today, tungsten carbide wire drawing dies to occupy an important position in the wire drawing industry. In this article, we will bring you the following characteristics of carbide wire drawing dies: 1. Strong power resistance During the process of wire drawing and extrusion, the wire drawing die will be subject to large extrusion, bending stress, impact, and other messy loads. Therefore, the material selected to make the wire drawing die should have high power resistance and outstanding hardenability after heat treatment to ensure that the die can be uniformly hardened. 2. Excellent wear resistance The wire drawing die should have high wear resistance to ensure normal service life and mass production of high-quality wire. Generally speaking, the hardness of tungsten carbide is directly proporti...
