Description

A kind of device that utilizes the single nickel salt electroforming solution to prepare the nickel cavity liner

Technical field

The invention belongs to the metallic substance cavity liner and make the field, relate to the device that a kind of electrocasting method prepares the nickel cavity liner.

Background technology

Up to the present, the method for various countries processing cavity liner mainly contains car, dashes, revolves, squeezes, five kinds of electroforming, and China has just begun the work of this respect from the fifties, is especially obtaining bigger progress aspect punching press, the cold spinning.The research work of the electroforming processing aspect of cavity liner just just starts the end of the eighties, though obtained certain progress, also need pass through big quantity research and exploration.The cavity liner of learning electroforming processing from the file of abroad having deciphered all has bigger superiority than the cavity liner of spinning processing, punch process at aspects such as structure property, broken first effects.Employing electroforming method for processing can obtain the cavity liner of superfine crystal particle, and the internal stress of cavity liner is less, wall thickness is even.By control electroforming process parameter, can effectively control the heterogeneous microstructure of cavity liner, thereby improve shaped charge action.

Domestic research for the electroformed nickel cavity liner is at the early-stage.The preparation of nickel cavity liner is higher than general plating or electroforming requirement in the plane, because the core of cavity liner is conical, the electroforming thickness of the requirement awl end and the vertex of a cone must be consistent.The preparation of nickel cavity liner is to the performance requriements strictness, must be in the waters bath with thermostatic control of five or six ten degree electroforming tens hours continuously, and product is bigger, general constant temperature water bath can't satisfy above-mentioned requirements.Simultaneously, consider and produce reality, also will be designed to be fit to the circulator bath mode of batch process.Also there is not at present to satisfy simultaneously the above electroforming apparatus that requires.

Summary of the invention

The utility model provides a kind of electroforming apparatus, and this equipment can keep the electroforming consistency of thickness of the awl end and the vertex of a cone when preparation nickel cavity liner, can also keep in the foundry goods additive component even, and the continuous electroforming environment of thermostatic circulation bath is provided simultaneously.

A kind of device that utilizes electrocasting method to prepare the nickel cavity liner comprises experiment table, swivel arrangement, water bath, electrotyping bath, shielding case, water pump, heating tank, heating tube, return line, water temperature control system.Swivel arrangement is positioned on the experiment table, and electrotyping bath is installed in the water bath, and shielding case is installed in the electrotyping bath.Heating tank is positioned over electrotyping bath one side, and heating tube hangs on the edge of heating tank, and is detachable, in the heating of the bottom of groove, with heating tank independence heat hot water and constant with the water temperature control system control water temperature.Hot water in the heating tank is by in the water pump suction water bath, water bath locates to bore a hole with the return line heating tank that is linked back more than 1/2nd, the height that arrives this hole when water level just utilizes difference of altitude to flow back to heating tank automatically, forms water cycle, makes the water bath water temperature constant.Hang the nickel plate as anode on the electroforming cell wall, the direct supply anode connects the nickel plate, thereby negative electrode is connected to connection core on the swivel arrangement.The swivel arrangement that connects power cathode makes the charged and drive core rotation of core by the metal union lever.Core is electroforming in shielding case, and full hole is bored on the whole body of shielding case, and the number in hole is directly proportional with the diameter of the taper core of equal altitudes on the equal height, thereby makes the surface of taper core be coated with the nickel of uniform thickness.Utilize the bottle that instils to come even supplemented by additives in the electroforming process.

This device also can be used as other conical or cylindrical core that need rotate and needs the plating of water bath with thermostatic control or the preparation of electoformed product.

Embodiment

Example 1

Swivel arrangement is positioned on the experiment table.Swivel arrangement links to each other with the metal union lever of negative electrode core with a stainless steel, drives core and rotates, and swivel arrangement links to each other with the negative pole of direct current electroforming power supply simultaneously, makes core conduct electricity the negative electrode when making it do electroforming by the metal union lever.Pour an amount of water in the heating tank into, put into the heating tube of a suspension type bottom heating, heating tube hangs on the edge of heating tank, places the thermopair of a measuring water temperature in the heating tank again, and thermopair links to each other with temperature controlling system, in order to control water temperature.An amount of water is put in water bath the inside, places electrotyping bath in the water, sends into water bath with the water in the pump handle heating tank, bores a hole at the sixth place of distance water bath upper limb with the conduit heating tank that is linked back, and makes the water cycle of water bath and heating tank mobile.In electrotyping bath, pour electroforming solution into, put into a whole body and bore the insulating shielding case in full hole, core is electroforming in shielding case, and the number in hole is directly proportional with the diameter of the taper core of equal altitudes on the equal height, and the effect of shielding case is to make core thickness electroforming equably in electroforming solution.The groove of electrotyping bath is along last suspension anode nickel plates, and the nickel plate links to each other with the positive pole of direct current electroforming power supply.Before the electroforming, make the energising of heating tank and water pump earlier, the interior temperature of post-heating groove, water bath and electrotyping bath all reached default steady temperature in several hours.Open swivel arrangement and direct supply, the beginning electroforming.In the electroforming process with even supplemented by additives in the bottle dealing plating bath that instils.Shut down after the electroforming and the taking-up core, carry out the demoulding and aftertreatment.
