Description
Technical Field
The invention belongs to the technical field of enameled wire production, and particularly relates to a painting die for a fine enameled wire.
Background
Since the birth of enameled wires, the production of fine enameled wires is still performed by adopting a traditional felt method. The method has the advantages of simple operation, and the thickness of the paint layer can be adjusted by adjusting the pressure of the felt plate or the rotating speed of the paint delivery roller. However, the defects are obvious, firstly, the felt is hardened and loses elasticity after being used for a long time, so that the problems of easy broken wire, uneven painting and the like are caused, the product quality is directly affected, and the felt needs to be replaced frequently; secondly, the paint liquid used for the felt painting has small viscosity, and a large amount of solvent and diluent are used for paint mixing, so that the production cost of the enameled wire is increased, and the environmental pollution is caused; thirdly, the speed of the vehicle is slower, and the yield is lower. In order to solve the above problems, a conventional poly-crystal painting mold (as shown in fig. 1) has appeared, and the mold has the following problems in use: the fluidity of the paint liquid in the die sleeve is poor, impurities in the paint liquid in the die sleeve are difficult to discharge, paint tumors are easy to generate, and the wire breakage of the enameled wire is caused.
Disclosure of Invention
In order to solve the technical problems, the invention provides a painting die for a fine enameled wire.
In order to achieve the purpose of the invention, the invention adopts the following technical scheme:
The utility model provides a fine enameled wire is with japanning mould, includes mold core unit and tubular die sleeve, the die sleeve divide into thin neck and arc location shoulder along the axial, be equipped with on the inboard global of thin neck and be used for inlaying the dress mold core unit's step, be equipped with on the mold core unit with the coaxial and the japanning hole that link up mutually with the die sleeve lumen of die sleeve, the internal diameter of die sleeve by step department is kept away from the one end of mold core unit increases gradually and forms the entry segment of 35-40 degrees cone angles.
The technical scheme is as follows: the die core unit is positioned in the die sleeve, the end face, far away from the step, of the die core unit is flush with the end face of the die sleeve, the length of the die core unit accounts for 35-40% of the total length of the die sleeve, and the total length of the die sleeve is 9-10mm.
The technical scheme is as follows: the die core unit comprises a polycrystalline die core and a sintered body which is fixed outside the polycrystalline die core in a coating mode after sintering, and the polycrystalline die core, the sintered body, the paint coating hole and the die sleeve are coaxially arranged.
The technical scheme is as follows: the outer diameter of the arcuate locating shoulder increases gradually away from the end of the die core unit.
The technical scheme is as follows: the die sleeve is made of stainless steel materials.
The invention has the beneficial effects that:
(1) The invention can replace the traditional felt painting mode, thereby effectively solving the problems of poor quality, serious pollution, low yield and the like of products produced by painting a fine enamelled wire felt machine.
The advantages of the invention over felt lacquering are embodied in:
The invention can directly paint the fine wire with high solid content and high viscosity without dilution, thus saving a large amount of solvents and diluents, reducing the production cost of the fine enameled wire and reducing the pollution of gases such as cresol, dimethylbenzene and the like to the environment;
When the painting mold is used, the painting mold is arranged in the clamping groove of the painting frame through the thin neck part, the arc-shaped positioning shoulder part can prevent the painting mold from moving along the moving direction of the micro wire during painting, and simultaneously can enable the painting mold to have a self-centering function, namely, the arc-shaped positioning shoulder part has a universal adjusting function, so that the painting mold can deflect and swing relative to the center of the micro wire, and the centers of a painting hole and the micro enamelled wire are ensured to coincide, thereby ensuring the uniform painting, and simultaneously avoiding the problem of broken micro wire;
The size and specification of the micro enamelled wire produced by the painting die cannot change, so that the stability of each performance of the micro enamelled wire is ensured; in addition, the painting die disclosed by the invention can be suitable for high-speed production of fine enamelled wires, so that the production efficiency is greatly improved.
The painting die disclosed by the invention has long service life, and the production difficulty of the fine enameled wire is reduced.
(2) The advantages of the painting die of the invention compared with the traditional polycrystalline painting die are as follows:
Firstly, when the traditional polycrystalline painting die is transversely inserted into a painting frame, the sagging amplitude of an inlet section of the die is large, so that a painting hole in the die deviates from the center of the micro-fine wire, and further the problems of painting deviation, uneven painting, wire breakage and the like are caused. The invention reduces the weight of the die, the length of the die is reduced to 9-10mm from the original 21mm, and in addition, the die sleeve is replaced by aluminum alloy, so that the weight of the die is reduced to about 0.55g from the original 2.8g, and the weight of the die is reduced by 80%. The weight of the die is reduced, the die is facilitated to be transversely inserted into the painting frame, the thin neck part of the die sleeve is tightly combined with the painting frame, the sagging amplitude of the inlet section of the die sleeve is obviously reduced, the coincidence of the center of the die and the center of the fine wire is high in the painting process of the die, and the problems of deviation, broken wire and the like of the fine wire enamel are solved.
Secondly, the die sleeve of the traditional polycrystalline painting die is long, so that the storage amount of paint liquid in the die sleeve is large, and the adhesion acting force between the paint liquid and the micro-wires is large, namely the running resistance of the micro-wires is increased. Compared with the traditional polycrystalline painting die, the internal space of the die sleeve is reduced, so that the paint storage amount of the internal space of the die sleeve is reduced, the original paint storage amount is changed from 0.91mL to 0.50mL, and the paint storage amount is reduced by 38%. Thus, the resistance generated by mutual adhesion with the paint liquid when the micro-wires run can be reduced, which is the core problem of micro-wire breakage.
Finally, the invention removes the straight hole area in the traditional polycrystalline painting mould, the angle of the paint inlet of the mould is increased, the angle is changed from 10-15 degrees of the traditional polycrystalline painting mould to 35-40 degrees, the residual quantity of insulating paint liquid in the straight hole area in the mould sleeve is reduced, the paint liquid is enabled to rotate at the paint inlet, the fluidity of the paint liquid is enhanced, the impurities and the like in the paint liquid are effectively discharged, and broken lines of micro fine wires due to paint tumor are avoided.
The invention improves the processing precision and the level of the painting mould, the minimum size of the polycrystalline painting mould can be manufactured to be 0.100mm, and the specification of the painting mould is improved by one height.
(3) The length of the mold core unit accounts for 35-40% of the total length of the mold sleeve, which is beneficial to keeping balance of the mold on a painting frame during painting, namely avoiding influence on painting uniformity caused by unbalance of the mold due to uneven weight distribution.
