Description
Technical Field
The invention relates to the technical field of metal processing, in particular to a metal antique finishing process and metal surface polishing equipment.
Background
The noble metal mainly refers to gold, silver and platinum group metals, such as ruthenium, rhodium, palladium, osmium, iridium, platinum and other metal elements. Most of noble metals have beautiful colors and strong chemical stability, are not easy to generate chemical reaction with other chemical substances under common conditions, and are often used for manufacturing ornaments, such as jewelries, ornaments and the like, and the surfaces of the manufactured ornaments and the noble metals have bright metal colors. However, due to market demands, the appearance of some ornaments or ornaments needs to show the visual effect of long time or vicissitude, but the effect of the existing antique finishing process is not real enough and does not meet the requirements of customers.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a metal antiquing process which is simple in process steps, and the surface of a processed metal product can show a retro visual effect and meet the requirements of customers.
The invention also provides metal surface polishing equipment which can perform shape-entering polishing processing on the metal surface needing to be made old so that the polished surface of the metal product presents a vivid antique effect.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a metal antique finishing process comprises the following steps:
step one, carrying out electrolytic oil removal treatment on a metal workpiece in oil removal liquid;
step two, carrying out acid treatment on the metal workpiece treated in the step one in an acid salt solution;
step three, carrying out surface chemical deposition treatment on the metal workpiece treated in the step two in an electrochemical deposition gold solution to electroplate a black ruthenium layer on the surface of the metal workpiece;
and step four, polishing the surface of the metal workpiece treated in the step three by using metal surface polishing equipment, polishing off part of the black ruthenium layer on the surface of the metal workpiece, and enabling the surface of the metal workpiece to have an old effect by using residual black ruthenium.
In the first step, the voltage for electrolytic degreasing is 5-7V, the temperature is 25-30 ℃, and the electrolytic degreasing time is 30-120 s.
In the first step, each liter of the deoiling liquid comprises 30-70g of sodium hydroxide, 15-60g of sodium carbonate and 20-80g of dipotassium hydrogen phosphate.
The method comprises the following steps of performing electrochemical deposition on a gold solution, wherein a platinum-titanium mesh is used as an anode in the third step, the electrochemical deposition gold solution comprises ruthenium salt, phosphoric acid and a blackening agent, and the ratio of the ruthenium salt to the phosphoric acid to the blackening agent is 7-9:0.5: 1.5.
Wherein, in the third step, the pH value is 0.8-1.2, the temperature is 20-35 ℃, and the current concentration is 3-5A/dm when the surface chemical deposition treatment is carried out2The plating time is 20-150 s.
When the pH value is less than 0.8, the coating can fall off, and when the pH value is more than 1.2, the color of the coating is not black. When the temperature is lower than 20 ℃ during electroplating, the coating is not easy to deposit, and when the temperature is higher than 35 ℃, the coating can generate fog. When the current concentration is lower than 3A/dm2When the film is placed at a low potential, the film is difficult to cover black ruthenium and is higher than 3.5A/dm2The coating may burn during the process. When the plating time is less than 20 seconds, the plating layer is not thick enough, and when the plating time is more than 150 seconds, the plating layer is deposited too thick and comes off.
Specifically, in the electroplating process, pure water with lower conductivity is used, the conductivity is less than 3 mu S/cm, so that the pollution of the electroplating water is avoided, and the pure water does not contain organic substances, silicon, boron and other components.

Specifically, the grinding time is 30-60s, and the shape of the grinding sand comprises a polygon and a circle.
The grain size of the grinding sand is set to be 1-20 mm, so that the grinding sand can conveniently grind smaller metal workpieces and positions at the concave positions, and the grinding sand is light in weight, so that the situation that the black ruthenium coating on the surface of the metal workpiece is completely ground and polished during grinding of the grinding sand can be avoided, when the grain size is too small, the quality of the grinding sand is too light, the black ruthenium coating on the surface of the metal workpiece is difficult to polish and polish by the grinding sand, but when the grain size is more than 20 mm, the quality of the grinding sand is too large, and the black ruthenium coating on the surface of the metal workpiece is easily polished and polished.

Two sets of centrifugal blocks 34 are arranged, the two sets of centrifugal blocks 34 are respectively arranged on an output shaft at the upper end of the vibrating motor 33 and an output shaft at the lower end of the vibrating motor 33, the farthest distance from the edge of the centrifugal block 34 at the upper end to the output shaft is smaller than the farthest distance from the edge of the centrifugal block 34 at the lower end to the output shaft, under the condition that the rotating speeds are the same, the centrifugal force generated by the centrifugal block 34 at the upper end is smaller than the centrifugal force generated by the centrifugal block 34 at the lower end, and then the vibration amplitude of the centrifugal block 34 at the upper end, which drives the vibrating motor 33, the connecting frame 32 and the charging bucket 2, is smaller than the vibration amplitude of the centrifugal block 34 at the lower end, which drives the vibrating motor 33, the connecting frame 32 and the charging bucket.
The vibration spring 35 is arranged between the connecting frame 32 and the vibrator base 31, so that when the vibration motor 33 and the connecting frame 32 vibrate, the vibrator base 31 at the bottom cannot vibrate along with the vibration, and the device can be stably placed on the ground to avoid vibration when in work.
The ultrasonic device comprises an ultrasonic generator 51 arranged on the frame 1 and an ultrasonic transducer 52 arranged on the charging bucket 2 and electrically connected with the ultrasonic generator 51. The energy is indirectly provided for the grinding sand in the charging bucket 2 through the matching of the ultrasonic generator 51 and the ultrasonic transducer 52, and the energy is synchronously applied with the vibration device, so that the polishing effect and the polishing efficiency are favorably improved.
The rotation driving device comprises a first bevel gear 41 fixedly arranged on the periphery of the charging bucket 2, a second bevel gear 42 meshed with the first bevel gear 41 and a driving part 43 used for driving the second bevel gear 42 to rotate, and the driving part 43 is arranged on the rack 1. Specifically, the driving member 43 is a speed-adjustable motor.
During operation, the driving member 43 is started, the driving member 43 drives the second bevel gear 42 to rotate, and the second bevel gear 42 rotates to drive the first bevel gear 41 to rotate, so as to drive the charging bucket 2 to rotate synchronously.
The rotation driving device further comprises a supporting frame 44 with one end fixedly connected with the connecting frame 32, and the bottom of the supporting frame 44 is connected with the machine frame 1 through a supporting rod 45 with certain elasticity. The supporting frame 44 can move approximately along with the swinging of the connecting frame 32, so that the driving member 43 and the first bevel gear 41 can swing synchronously with the second bevel gear 42, which is beneficial to preventing the first bevel gear 41 and the second bevel gear 42 from being separated, and ensuring that the rotation driving device can normally drive the charging bucket 2 to rotate.
Specifically, the structures of the metal surface grinding apparatuses used in examples 1 to 3 were the same as those of this example.
While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
