The wire drawing machine must ensure that the filament between the fixed speed wheel and the take-up reel has a certain tension to complete the drawing process. The fixed speed wheel set is driven by the main motor, the speed is determined by the product specifications, and the line speed is also fixed. The wire speed of the take-up reel increases as the diameter of the take-up reel increases. In order to ensure a certain tension, that is, to maintain the line speed of wire feeding and wire feeding, it is necessary to continuously reduce the rotation speed of the take-up reel to ensure that the wire receiving speed of the take-up reel is constant.
The principle of wire drawing machine can be divided into metal wire drawing machine, plastic wire drawing machine and bamboo wire drawing machine according to its application. The metal wire drawing machine belongs to the prefabrication equipment for the production of metal products such as standard parts. The purpose is to pull the wire or bar of the metal product manufacturing enterprise, which is produced and transported by the steel manufacturer to the standard parts, through the wire drawing machine to make the wire or bar. The diameter, roundness, internal metallographic structure, surface finish and straightness all meet the raw material processing requirements for the production of metal parts such as standard parts.
Therefore, the quality of pretreatment of wire rods or bars by wire drawing machines is directly related to the product quality of standard parts and other metal products manufacturers. Wire drawing machine belongs to metal wire drawing machine for metal products equipment industry. Wire drawing machine is widely used in the production and pre-processing of metal products such as steel wire, rope, prestressed steel wire and standard parts.
The main feature of the plastic wire drawing machine is that there is an exhaust port on the barrel, and the barrel is connected at least two or more. The pitch of the screw in one of the barrels is different from that of the latter, and does not need to be stirred by a plastic mixer, and can absorb the moisture generated by the plastic during the stirring. The drawn plastic wire has a uniform thickness, is smooth, is not easy to break, and has high work efficiency. , low energy consumption.
