How to solve the possible problems in the process of wire drawing machine operation

by:HONTA     2020-07-29

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) And so on. How to solve the operating wire drawing machine possible problems in the process of wire drawing machine pull monofilament surface oxidation reason isn't enough cooling liquid of saponification liquid content in the sealed chamber, this will increase the friction force of monofilament with the idler pulley, thereby enabling monofilament temperature rise again, causing monofilament surface oxidation. Seal chamber of the cooling water pressure and water quantity is not enough, make monofilament cannot achieve satisfactory cooling effect. 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. 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. Product outside diameter deviation of precise control due to the continuous production of equipment for copper wire drawing, wire drawing speed will also gradually out of sync with annealing, when drawing due to the traction speed fast when slow and make the wire diameter appear continuously, irregular section of large section of the small phenomenon, the causes of this phenomenon are the following: copper wire on the annealing wheel jitter, this makes the copper wire in the loose tight under the state of annealing, annealing of age when current density is small, and the strength of the copper wire at high speed is relatively low, so easy to cause in annealed copper wire wheel lighter, make the surface of the copper wire due to the effect of spark wire diameter is not uniform. Main motor gearbox of the wear and tear caused by long-term use, it can make the drawing of the metering speed and haulage speed and linear velocity does not match, so as to form a monofilament fine-drawn store the instability of tension on the wire wheel, production workshop USES may be more pressure, which can cause wire drawing machine age when the pressure of the pump is small, it also makes a store of wire tension is not constant, due to the line speed is constant, this makes the drawing by pulling force is not constant value, which can cause monofilament diameter deviation can't accurate control. Solution: to good lubrication of wire storing device, avoid reverse its operate at a high speed of the line of friction and thus make the line of fine; Adjust the line tension, make drawing schedule is always close to the annealing wheel; To ensure that the annealing wheel rims in good condition, avoid the rims of the surface defects and make the annealing current is not stable. The above is the wire drawing machine related matters, hope to be able to help you.
