Description
Technical Field
The invention belongs to the technical field of electrochemical machining, and particularly relates to a device for dissolving and removing a metal capillary electroforming core mold and a demolding method.
Background
Metal capillary tubes with an inner diameter of several hundred micrometers or less are used in many fields, such as chromatography tubes, signal tubes of automated instruments, probe tubes for electronic tests, optical fiber connecting tubes, and injection needles. Electroforming is an additive precision manufacturing technique. The method is a process of utilizing the principle of metal ion cathode electrodeposition to deposit metal, alloy or metal-based composite material with a certain thickness on the surface of a core mold, and separating the core mold from the metal, alloy or metal-based composite material by utilizing a certain technical means to obtain a product. The electroforming has the advantages of coordinated regulation and control of material organization structure-performance-surface morphology, high precision, small internal stress, compact material, low implementation process temperature, wide applicable material range and the like, and is particularly suitable for precise metal components with low rigidity and micro-scale.
Because electroforming mainly realizes the forming process of an electroformed product by copying the geometric shape of a core mould, after the electroforming process is finished, the demoulding step of the electroforming core mould is the key and core step of electroforming. For electroforming metal capillaries, the electroforming mandrel used is often a fine wire because of the small inner diameter of the capillary, and the fine wire is wrapped inside the metal capillary after electroforming. This results in very challenging removal of the metal capillary electroforming mandrel. From the principle analysis, there are several demolding methods such as thermal expansion and cold shrinkage method, mechanical deformation method, dissolution method, etc. The thermal expansion and cold shrinkage method is characterized in that different thermal expansion coefficients of different metals are utilized, and the volume of the metals is expanded or contracted in different sizes through temperature change, so that the bonding force between the core mold and the deposited layer is damaged, and a gap is formed between the core mold and the deposited layer to achieve the purpose of demolding. For electroforming of metal capillaries, the expansion and contraction method is not ideal enough, and the reasons are that: (1) the diameter of the metal wire of the electroforming core mold is generally from several micrometers to tens of micrometers, and the difference of the thermal expansion coefficients between the core mold and the deposited layer metal is not large, so that the clearance generated by the volume change caused by the temperature change of the core mold and the deposited layer metal is not enough to support the demolding operation; (2) the metal of the tube wall of the capillary tube is generally thin, the capillary tube is easy to deform and even crack in the shock heating and shock cooling process, and the metallographic phase of the metal of a deposited layer can be changed by the overhigh temperature, so that the actual service performance of the metal can be influenced. The mechanical deformation method is a method of drawing a core mold out of a capillary tube by stretching the core mold to cause elastic or plastic deformation without breaking to reduce the cross-sectional area of the core mold. Because the core mould is slender and the binding force between the metal capillary and the core mould is linearly increased with the length of the metal capillary and the core mould, when the electroformed capillary is longer, huge pulling force is needed, the core mould is very easy to break, and further, part of the core mould is still remained in the capillary and cannot be taken out, so that the difficulty of integrally demoulding the capillary by adopting the method is high, and the success rate is low. The dissolution method is a method of removing a core mold using a chemical solution without damaging the deposited layer metal. The dissolution method is not affected by temperature and external force, and the dissolution solution is easy to prepare, and is a preferable method for removing the mandrel, but the method has the following problems for releasing the electroformed capillary: the inner diameter of the capillary tube is small, and the solution is restrained by huge surface tension in the capillary tube, under the condition, the mass transfer is extremely slow, the dissolved product is difficult to discharge, and the new dissolved solution is difficult to enter, so that the method has certain difficulty in realizing the demoulding of the capillary tube directly. Japanese patent nos. JP 2006-. Therefore, the invention provides a device for dissolving and removing the electroforming core mould of the metal capillary and a method for removing the electroforming core mould of the metal capillary based on the device, so as to realize the simple, high-efficiency and high-success-rate demoulding of the electroforming capillary.
