Abstract
The present invention discloses production technology of a varnish coated copper round wire which has the advantages of simple manufacturing processes and good using quality for people. The production technology has the following processes that (1) a copper round wire which is purchased from a market is put in a wire drawing machine to be pulled into a required specification at the line speed of 1500 m per minute, and the specification of the diameter of the copper round wire which is purchased from the market is 2.6 centimeters; (2) the copper round wire which is pulled by the wire drawing machine is taken out to be put in an annealing furnace at the speed of 200 to 300 m per minute; (3) an insulating layer is coated on a drying furnace, and a raw material formula of the isolating layer comprises polyurethane resin and polyester imido resin; (4) the temperature of the drying furnace is adjusted to 380 to 420 DEG, and the copper round wire is dried at the speed of 200 to 250 m per minute; (5) the temperature in a varnish box in a varnish coating machine is adjusted between 35 and 45 DEG, and a finished product varnish material is circulated to a varnish groove of the varnish coating machine; (6) a product of the varnish coated copper round wire is packed into a stock. The product manufactured by the technology of the present invention is widely used for high temperature resistance winding coils and obtains consistent favorable comments of wide users.
Description
Technical field
The present invention relates to the production technology of a kind of material of high temperature resistant winding coil, especially relate to a kind of production technology of enamelling cuprum round line.
Background technology
The production technology of traditional enamelling cuprum round line is copper round wire (a base line)---backguy---[annealing---japanning---oven dry---cooling]---the enamelling cuprum round line product.Copper round wire base line is drawn into the copper round wire of each specification through the drawing machine of each model, repeat repeatedly through entering enamelling machine annealing furnace annealing back [annealing---japanning---oven dry---is cooled off] after the assay was approved, the enamelling cuprum round line product.Be provided with rationally inadequately but technological parameter generally can occur in this technical process, the coating layer thickness consistency is poor, causes every performance imbalance, is reflected in straight weldering decreased performance or heat resistance deficiency, and anti-softening puncture temperature is low, and caloric impact temperature is low etc.In addition, the product of this explained hereafter connects in the process in weldering must remove enamelled coating, causes inefficiency.
Summary of the invention
At the technical problem of above-mentioned existence, the present invention proposes the production technology of the enamelling cuprum round line that a kind of technology is simple, service quality is good.
Technical scheme of the present invention is achieved in that a kind of production technology of enamelling cuprum round line, and its production process is as follows:
(1), with the copper round wire that market is purchased, put into drawing machine and carry out backguy and pull into required specification with per minute 1500 rice noodles speed;
(2), take out and to put into annealing furnace, anneal with the speed of per minute 200-300 rice;
(3), on baker, be coated with insulating barrier, the raw material of the prescription of usefulness polyurethane resin and polyester imido resin in the insulating barrier;
(4), oven drying temperature is adjusted into 380-420 ℃, dry with per minute 200-250 rice speed;
(5), the temperature of lacquer in the case in the enameling machine adjusted between 35-45 ℃, the finished product paint vehicle is circulated in the paint bath of enameling machine;
(6), the stock is gone in the enamelling cuprum round line packing of product.
Technology device therefor raw material sources of the present invention are as follows: drawing machine is the FD type equipment of east, Kunshan, Jiangsu Province sharp mechanical motor Co., Ltd; Annealing furnace, baker, enameling machine are the equipment of Changzhou, Jiangsu Province Jiujiang machinery plant; The raw material of the prescription of polyurethane resin and polyester imido resin is the product of granary, Jiangsu Province Dong Te coating factory; The finished product paint vehicle is the product of eastern special coating (granary) Co., Ltd; Copper round wire is the universal product on the market.
Because the product that technology of the present invention is produced has multiple particularity, that is contain polyurethane resin and polyester imido resin in the insulating barrier simultaneously, and polyurethane resin requires the low speed of production of temperature also very fast when enamel-cover process oven dry film forming, otherwise will reduce the scolding tin performance, on the other hand, polyester imido resin requires bake out temperature higher again, speed of production can not be too fast, otherwise it is (low as softening puncture temperature to cause imidization degree deficiency to influence heat resistance, caloric impact temperature is low etc.), so, the correct production equipment of technology utilization of the present invention, reasonable technological parameter is set, determine best technological temperature, guaranteed the consistency of thickness of insulating layer, and technical process does not repeat, and its advantage is that technology is simple, service quality is good.Overcome in original technology technological parameter fully and be provided with rationally inadequately, the coating layer thickness consistency is poor, causes every performance imbalance, is reflected in straight weldering decreased performance or heat resistance deficiency, and anti-softening puncture temperature is low, the defective that caloric impact temperature is low.Simultaneously, the product of explained hereafter of the present invention connects in the process and can directly carry out in weldering, need not remove insulating barrier, high efficiency.
