How to choose the wire drawing machine
Wire drawing machine is a widely used mechanical equipment in industrial applications, it used in machinery manufacturing, hardware processing, petrochemical industry, plastic, bamboo and wood products, wire and cable and other industries.
The working principle of wire drawing machine
The original wire is formed into a finished product through a fixed speed wheel set and a wire drawing mold, and is transported to the retracting wheel by the last fixed speed wheel at a certain speed through the row guide wheel.
Drawing machine is to ensure that there is a certain tension between the fixed speed wheel and the retracting wheel to complete the drawing process.
The fixed-speed wheel set is driven by the main motor, the speed varies with the product specifications, and the linear speed is also certain.The linear velocity of the retracting wheel increases with the diameter of the retracting wheel.In order to ensure a certain tension, that is, to keep the wire feeding and wire receiving speed consistent, it is necessary to constantly reduce the speed of the wire receiving wheel to ensure that the wire receiving speed of the wire receiving wheel is constant.
The speed regulation of the retractable wheel is realized by the speed regulating motor.
Metal wire-drawing machine for standard parts and other metal products production pre-processing;
Plastic wire-drawing machine is used as a complete set of special equipment for deep processing of hollow, solid round wire or flat wire by using polyester, nylon, polyethylene, polypropylene and polyester chip as raw materials in the plastic products industry.
Bamboo and wood wire-drawing machine is a special equipment for bamboo and wood products industry, such as chopsticks, toothpicks, barbecue sticks, etc., to pull out bamboo threads and reprocess wood threads.
Type of wire drawing machine
Wire drawing machine according to its use can be divided into metal wire drawing machine, plastic wire drawing machine, bamboo wire drawing machine.
Metal wire drawing machine: belonging to standard parts and other metal products production processing equipment, the purpose is to put the production by the steel manufacturer to standard parts and other metal products production enterprise of wire or rod through the wire drawing machine drawing processing, make the diameter of wire or rod, roundness, internal metallurgical structure, surface finish and straightening degrees are required for standard parts and other metal products production of raw materials processing requirements.Therefore, the quality of wire or bar pretreatment by wire drawing machine is directly related to the quality of standard parts and other metal products.Wire drawing machine belongs to metal wire drawing machine in metal products equipment industry. Wire drawing machine is widely used in the production and pre-processing of metal products such as steel wire, wire making, prestressed steel wire, standard parts, etc.
Plastic wire-drawing machine: the main feature of the energy-saving plastic wire-drawing machine is to have an exhaust port on the feed barrel, and the feed barrel has at least two or more connected.The screw pitch in the first section of the material barrel is different from that after, do not need plastic agitator to agitate, and can suck out the plastic in agitating the water that produces, the plastic wire that pulls, thickness is even, smooth, not easy to break silk, and work efficiency is high, energy consumption is little.
How to choose metal wire drawing machine :
1 Watch the structure.
Small and medium drawing machines generally want high speed, it can be seen whether the body of its equipment is a casting.If it were not for the casting, there would be a great deal of vibration at high speed, and the machine would not be able to run at high speed.Castings cost more, so the price is higher.Welding parts generally due to low production costs, so its price is relatively low.Large factories are generally used in casting, welding parts are generally produced in small factories.
2. Look at the choice of bearing.
Good quality wire-drawing machine, its bearings are used in famous bear from Sweden or Germany or other quality suppliers. generally three or four years do not have to change.
And some of the low price of the wire drawing machine bearing not good quality but low price, with a year after the basic will be replaced by the bearing.
3 Tower wheel selection.The big factory is generally choose the tower wheel of famous brand manufacturers, the price will be relatively high, because the spraying thickness of the tower wheel produced by the big factory will be guaranteed, which is invisible to the naked eye, the tower wheel produced by the small factory is to take advantage of this loophole, the spraying thickness is a little thinner, its processing cost will be much lower, and the service life will be much shorter.
4. Look at the gears.
SSS production of the middle pull machine gear are required to grind teeth and surface accuracy should reach five accuracy above. other manufacturers low cost of drawing machines are not even hobbing, let alone grinding teeth, a year after the machine is like a scattered.
5. The selection of electrical components. SSS production wire drawing machine its frequency converter, low voltage distribution components, will choose the import brand or other china famous brand , so the price is higher, but the quality is guaranteed. some unknown electrical component is no good, .our special wiredrawing frequency converter, its tension stability, the range of adaptability has very high standard to prove in frequency converter stability and wide range.
