Direction of travel, including the payingoff mechanism, annealing mechanism, cooling body, japanning mechanism, baking mechanism, lubrication coating set gradually
Mechanism and take-up mechanism, wherein payingoff mechanism includes draw drum, as shown in Figure 3 and Figure 4, on the unwrapping wire lid 101 at the top of draw drum
It is provided with protective cover 102, the circumferential side wall of protective cover 102 is smooth arc side wall, and the bottom of the curved wall and unwrapping wire lid 101
Face is tangent, and this smooth arc side wall transition design can effectively avoid the abrasion between wire body 1 and unwrapping wire lid 101, prevents wire body 1
There is surface damage when unwrapping wire is advanced, has ensured the surface quality of wire body 1, also the processing quality for final enameled wire provides guarantor
Barrier.
Be provided with brush plate 103 on protective cover 102, on brush plate 103 circumferentially uniform intervals be provided with it is outwardly extending
Hairbrush 104；It is provided with angle dial on brush plate 103, is provided with 18~40 hairbrush 104, and hairbrush on brush plate 103 altogether
104 diameter is 0.4~0.9mm.The setting of hairbrush 104 can effectively increase the laying tension of wire body 1, in 1 traveling process of wire body
Flexibility through hairbrush 104, which is blocked, can make wire body 1 keep tensioning state, and by 104 diameter of hairbrush and density of arranging
Rationally cooperation, is capable of the stability of 1 tension of effective guarantee wire body, prevents occurring the problem of broken string, loose ends in production of enamel wire,
Ensure that the continuity of enameled wire efficiently produces.Fixed lid 105 is additionally provided with above brush plate 103, locking member is tight by brush plate 103
Gu guaranteeing the mounting stability of brush plate 103 between protective cover 102 and fixed lid 105, preventing in 1 traveling process of wire body
There is mobile or dislocation in brush plate 103, improves the safety and steady that wire body 1 is advanced.
After 1 unwrapping wire of wire body across two layers of cleaning felt, anneal into annealing mechanism after brushing surface copper powder
Processing, annealing mechanism includes annealing furnace 201 in the present embodiment, and the annealing temperature of annealing furnace 201 is 450 DEG C~480 DEG C, as Fig. 5,
Shown in Fig. 6, annealing pipe 202 is provided in annealing furnace 201, the end of incoming cables of annealing pipe 202 and leading-out terminal are that outward opening is continuous
Widened flared structure, and the inner wall of the flared structure is the arc inner wall to smoothly transit, reduces wire body 1 in inlet wire
A possibility that end/leading-out terminal and 202 tube wall of annealing pipe contact, reduces the frictionally damage of wire body 1.201 top of annealing furnace is also set
It is equipped with high temperature protection steam channel, high temperature protection steam is filled with into annealing furnace 201, prevents wire body 1 from aoxidizing, which steams
Vapour is then the secondary use that waste heat is generated to baking mechanism.
Production practices prove, though wire body 1 is not contacted with 202 tube wall of annealing pipe in end of incoming cables/leading-out terminal, but there are still
The problem of galled spots scratches, it is puzzling, through multi-party verification, when technical staff has found that wire body 1 is advanced in annealing pipe 202,
When especially travel speed is very fast, due to the limitation of 202 length of annealing pipe, wire body 1 itself is easy to appear and naturally droops phenomenon, causes
The sagging position of wire body 1 is easy to be in contact with the bottom tube wall of annealing pipe 202, will cause wire body 1 along with the continuous traveling of wire body 1
Sustained damage.In the present embodiment the inner wall 205 of 202 bottom of annealing pipe be to lower recess arc inner wall (annealing pipe 202
Exterior design can be straight trip pipe or curved pipe design, need to only make arc of the inner wall 205 of 202 bottom of annealing pipe to lower recess
Inner wall), the arc-shaped recess of inner wall 205 is corresponding with the hang of wire body 1, so that wire body 1 is when there is hang,
Its hanging portion still keeps vacant state, will not be in contact with the inner wall 205 of annealing pipe 202, effectively prevent wire body 1 and annealing
The frictionally damage generated inside pipe 202 facilitates the final mass for ensureing subsequent enameled wire.
The end of incoming cables side of annealing pipe 202 is provided with preceding guard plate 203, and leading-out terminal side is provided with rear guard plate 204, preceding
Ceramic ring is provided on guard plate 203 and rear guard plate 204, the upper and lower ends of preceding guard plate 203 are arranged in parallel with side baffle,
The side baffle extends to the direction close to annealing pipe 202, and the frame face annealing pipe surrounded by side baffle and preceding guard plate 203
202 end of incoming cables, the structure of rear guard plate 204 are corresponding with preceding guard plate 203.The rear of annealing pipe 202 be provided with to wire body 1 into
The cooling cooling body of row, including cooling water tank 301, water sponge and air dryer 302 are scraped, wherein cooling water tank 301 is recirculated water
Case, and liquid-level floater valve is provided in cooling water tank 301.The setting of guard plate 204 and preceding guard plate 203 is avoided that annealing furnace afterwards
High-temperature gas in 201 sprays outward, the wire body 1 before both having avoided damage to annealing, also avoids the cooling effect for influencing cooling water tank 301
Fruit.
