Due to pull wire drawing machine of the surface of the monofilament has different degree of oxidation

wire drawing machine according to its USES can be divided into metal wire drawing machine, Used for standard parts and other metal products production preparation) , plastic wire drawing machine, Used in plastic products industry in polyester, nylon, polyethylene, polypropylene, polyester chip, etc as raw material to produce various hollow, solid wire or flat wire for deep processing of special equipment) , bamboo wire drawing machine, Used for bamboo and wood products in the industry for chopsticks, toothpicks, barbecue bar pull such as bamboo, wood wool reprocessing of special equipment) Such as wire drawing machine to pull out the cause of monofilament surfaces have different degree of oxidation of 1, sealed cooling liquid of saponification liquid levels in the room is not enough, it will increase the friction force of monofilament with the idler pulley, thereby enabling monofilament temperature rise again, causing monofilament surface oxidation. 2, seal chamber of the cooling water temperature is too high, more than 40 ℃, the sealed chamber of monofilament is less than the required cooling effect, causing monofilament after annealing temperature is still high, high temperatures in the presence of oxygen in the air. 3, seal chamber of the cooling water pressure and water is not enough, make monofilament cannot achieve satisfactory cooling effect. Solution: check the cooling circulating water equipment is operating normally, the cooling effect is normal; Every time to join in the seal chamber can improve saponification liquid concentration of substances, so that we can change the saponification liquid content in the cooling water, monofilament to ensure normal operation on the idler pulley; Check the water pressure is normal, of circulating water in production continuously according to the variation of water pressure to change into the sealed chamber in the cooling water pressure and water. Often has appeared frequently the phenomenon of broken wires of wire drawing production reason 1, due to the quality problems of various kinds of rod. In the process of production, rod material irregularly. Quality defects, which makes monofilament was all sorts of unpredictable tension in the wire drawing deformation pulled apart or cause drag mark. Less frequent when the situation in the rod material is good. 2, due to the current production of annealing is not constant, current suddenly on the high side, monofilament is pulled or by mutations in the process of annealing the strong current of fuse. 3, drawing die in the uninterrupted production due to normal wear and make the drawing die of sizing area. Above is the wire drawing machine related matters, hope to be able to help you
