Description
Technical Field
The invention belongs to the technical field of processing of copper-clad aluminum enameled wires, and particularly relates to a horizontal enamelling machine suitable for large-size enameled wires.
Background
As is well known, in the production process of a copper-clad aluminum enameled wire, the copper-clad aluminum enameled wire needs to be painted, a vertical enamelling machine is adopted in the market, and for the vertical enamelling machine, the process of multiple painting is adopted to gradually paint, that is, after one painting, one baking is carried out, although the painting operation of the wire rod can be realized, the implementation mode is directed to the large-sized enameled wire, such as: 2.0-4.0mm, it has the following drawbacks:
1) the outer diameter of the enameled wires is gradually increased after the enameled wires are subjected to multi-pass painting due to the fact that the same constant-speed wheel is used in multiple processes, so that tension formed by the enameled wires is unequal, breakage often occurs, once the enameled wires are broken, the dropped enameled wires interfere with other enameled wires, and the enameled wires are possibly twisted together with (or wrapped around) other enameled wires, so that the rejection rate is extremely high, the enameled wires are not convenient to process, and the production cost is extremely high;
2) in the vertical painting process, due to the self weight of the paint, if a special painting mold is not adopted, the paint is difficult to be uniformly coated on the surface of the wire rod, so that the paint on the surface of a product is not uniform, and the quality of an enameled wire is influenced;
3) the enamelling machine has a huge structure and large occupied space, and a drying oven is needed after each painting process, so the use cost of the equipment is very high;
4) the automatic climbing device has the advantages that the automatic climbing device is operation-defective, namely, the automatic climbing device needs multiple persons to operate in a matched mode, is complex to climb up and down, is high in working strength of workers, is tens of meters high in machine, and has great potential safety hazards in installation, carrying and operation processes.
Although the problem of wire breakage interference can be solved for the horizontal enamelling machine, the problem has an obvious defect: at present, all horizontal enamelling machines aim at the enamelling and coating of small-sized (about 1.0 mm) enamelled wires, and once the outer diameter of the enamelled wire is 2.0-4.0mm (even more than 4.0 mm), the enamelled wire has the defect of the above 1), and the tension formed by a plurality of enamelled wires is unequal, so that wire breakage often occurs.

As shown in fig. 1, the embodiment is suitable for a horizontal enamelling machine for large-size enamelled wires, and comprises a wire feeding system (i), a wire arranging system (ii), an enamelling system (iii), a drying system (iv), and a wire collecting system (v).
Specifically, the outer diameter of the large-size enameled wire is generally 2.0-4.0mm, and the horizontal enameling machine in the embodiment is particularly suitable for processing the enameled wire with the outer diameter of 2.0-4.0mm in a painting coating mode.
In this example, the wire feeding system includes an enameled wire unwinding mechanism t and a transferring wheel z for transferring the unwound enameled wire to the wire guiding system.
And the line-row system is used for horizontally, side-by-side and continuously transmitting the enameled wires.
And the painting system is arranged on the transmission path of the enameled wires and paints each enameled wire.
And the drying system is used for drying the enameled wire after painting.
And the wire take-up system is used for continuously completing the material collection of a plurality of painting and drying enameled wires.
Referring to fig. 2, the wire-moving system comprises a wire-moving wheel 1 and a driver, wherein the wire-moving wheel 1 comprises a fixed speed wheel 10 with a shaft axis extending along the horizontal direction and a transmission wheel 11 arranged in parallel with the fixed speed wheel 10.
Specifically, a plurality of V-shaped grooves 100 which are recessed inwards from the surface and are sequentially distributed at intervals are formed in the constant speed wheel 10, and the enameled wires fed from the wire feeding system firstly sequentially and continuously bypass each V-shaped groove 100 and the transmission wheel 11 and are transmitted from the transmission wheel 11 to the wire collecting system.
In this example, the plurality of enamel wires between the timing wheel 10 and the transmission wheel 11 include upper lines a positioned at upper portions thereof in parallel with each other, lower lines b positioned at lower portions thereof in parallel with each other, and winding lines c wound around the V-groove 100 and the transmission wheel 11.
The drying system (iv) includes a heat treatment furnace 2 disposed horizontally, an upper line (a) passing through the heat treatment furnace 2, and a lower line (b) located below the heat treatment furnace 2.
In this example, the wire-passing system (ii) has three sets, wherein three constant speed wheels 10 are coaxially arranged, three transmission wheels 11 are coaxially arranged, and the upper wire (a) of the enameled wire bypassing each set of wire-passing system (ii) passes through the same heat treatment furnace 2. Therefore, the enamelling machine can synchronously carry out enamelling and coating on a plurality of enamelled wires, the efficiency is improved, and the cost is saved.
As shown in fig. 3, the upward line a and the downward line b are arranged in a relatively intersecting manner, so that continuous winding can be realized, and the enameled wire is not bent due to the arrangement of the V-shaped groove.
Each winding wire c is tangentially matched with the inner arms at the two sides of the corresponding V-shaped groove 100.
As shown in fig. 4, the outer diameter of the winding line c increases gradually from one end of the axle of the constant velocity pulley 10 to the other end, and at this time, the vertical distance from the bottom of the V-shaped groove 100 to the axial line of the axle and the included angle formed by the two side arms of the V-shaped groove 100 are both disposed corresponding to the outer diameter of the winding line and in a direct proportion. Therefore, under the transmission of the same constant speed wheel and the same transmission wheel, the enamelled wires with different outer diameters are painted under relatively proper tension, and the probability of wire breakage of the enamelled wires caused by over-tightness or over-looseness of the enamelled wires is reduced.
In this example, the outer diameters of the plurality of winding lines c are varied in an arithmetic progression, and the vertical distances from the bottoms of the plurality of V-grooves 100 to the axial line of the axle of the constant velocity wheel 10 are correspondingly varied in an arithmetic progression. Like this can realize the successive layer of enameled wire and carry out the japanning operation with the same thickness, convenient implementation, and the quality of enameled wire can obtain guaranteeing.
Meanwhile, as is apparent from fig. 4, the angles formed by the V-shaped grooves 100 gradually increase from 83 °, 91 °, 99 °, 107 °, and 115 °, and the outer diameters of the corresponding winding lines c also correspondingly increase, and whether the angle change is regular or not depends on the thickening amount of the thickness of each paint. It should be noted that, although only five V-grooves 100 are shown in fig. 4, the V-grooves are added according to actual needs, and there are eight or nine or more conventional V-grooves.
Referring to fig. 5, the painting system (c) is located between the heat treatment furnace 2 and the constant speed wheel 10 and is arranged corresponding to each group of row line systems (c).
Specifically, the painting system c includes a painting base 3, painting heads 4 arranged side by side on the painting base 3 and in one-to-one correspondence with the upper line a, and painting molds 5 arranged on the painting base 3 and in one-to-one correspondence with the painting heads 4.
In this example, the painting head 4 includes a body 40 recessed from the top to form an avoiding notch 40a, and a liquid supply part for supplying paint to the avoiding notch 40a, wherein a spray hole a1 is formed at the bottom of the avoiding notch 40a, paint is sprayed from the spray hole a1 and wrapped around the periphery of an ascending line a passing through the avoiding notch 40a, and the excess paint directly flows back to the paint groove, so that circulating paint supply is realized.
As shown in fig. 6, the painting mold 5 is internally formed with a passage 50 for the upward line a to pass through, and the passage 50 includes a positioning section 500 and a painting section 501 sequentially distributed along the upward line moving direction.
The inner diameter of the positioning section 500 is larger than the outer diameter of the going-up line a and has a straight cylinder shape.
The inner diameter of the painting section 501 becomes gradually smaller along the moving direction of the upward line a and includes a reduced area s1 and a quantitative area d1 which are arranged in this order.
The internal diameter at the outlet of the dosing zone D1 is R, the external diameter to be passed through the upward line a is D, and the thickness to be painted is X, where R = D + 2X. This not only removes excess paint from the upstream surface, but also more evenly coats the upstream surface with paint.
In addition, the above enameling machine further includes a tensioner 6 which is located between the heat treatment furnace 2 and the transfer wheel 11 and performs tension adjustment of each of the passing upward lines a. That is, the tensioners are corresponding to each up-line, that is, each tensioner is independent, so that each enameled wire is painted under proper tension, thereby further reducing the probability of wire breakage of the enameled wire caused by over-tightening or over-loosening.
The tensioner 6 comprises a base frame 60 positioned between an ascending line a and a descending line b, a carriage 61 positioned above the base frame 60, a carriage wheel 62 arranged on the carriage 61, and an elastic member 63 arranged between the carriage 61 and the base frame 60 and maintaining the carriage 61 in a tendency to jack up upwards, the ascending line a being transmitted to the transmission wheel 11 by passing around the carriage wheel 62.
The rack wheel 62 is freely rotatably arranged on the rack seat 61 around the self axial direction, and a guide groove 620 matched with the ascending line a is formed on the rack wheel 62.
The guiding groove 620 is also a V-shaped groove, and the upper line a is tangentially matched with the inner arms at two sides of the V-shape. Not only the tensioning of the enameled wire is convenient to adjust, but also the transmission of the enameled wire is convenient under the action of the guide groove.
Similarly, the outer diameter of the ascending line a is gradually increased from one end of the wheel shaft of the constant speed wheel to the other end, and an included angle formed by two side arms of the V-shaped groove corresponds to the outer diameter of the ascending line and is in a proportional relation. Therefore, the tensioning adjustment of the enameled wires with different outer diameters is met.
In addition, the elastic member 63 is selected according to actual needs, and in this example, the elastic member 63 is a common spring.
And the wire take-up system comprises an enameled wire take-up mechanism 7 and a wire guide wheel 8 positioned above the transmission wheel 11.
In summary, the painting process of the present embodiment is as follows:
