Description

Rotary type electrolysis device

Technical Field

The invention relates to the technical field of metal product electrolysis equipment, in particular to a rotary electrolysis device.

Background

The electrolytic polishing is a method for finely processing the surface of a metal workpiece, and the method is to put the metal workpiece in an electrolytic polishing tank filled with electrolytic polishing liquid and electrify the electrolytic polishing liquid for electrolysis. Along with the electrolysis, a liquid film with high viscosity is formed on the surface of the metal workpiece, the thickness of the liquid film on the uneven surface of the metal workpiece is not uniformly distributed, the liquid film on the surface of the convex part is thin, and the liquid film on the surface of the other part is thick, so that the resistance of each part of the anode surface is different. The metal workpiece has small resistance at the convex part and high current density, so that the convex part is dissolved faster than the concave part. Therefore, the rough and uneven surface of the metal workpiece becomes smooth and bright, and the polishing effect is achieved.

At present, in the field of electrolytic polishing, particularly in the industry of stainless steel vacuum bottles and vacuum cups, linear electrolytic polishing equipment and technology are mostly adopted to carry out electrolytic polishing treatment on container liners. The method is characterized in that a container is usually placed on a conductive platform with an upward opening, the container is filled with specific electrolyte from top to bottom and then is connected with a power supply, and the electrolytic processing of polishing is carried out by utilizing the principle that metal surface microscopic salient points firstly undergo anodic dissolution in the specific electrolyte and under proper current density.

The applicant points out that the electrolytic polishing devices in the prior art integrally drive a plurality of cup bodies with upward cup mouths to be inserted into an electrolytic rod, and then pour electrolyte downwards into the interior of the cup bodies for electrolytic polishing. The applicant indicates that the prior art has the technical problems that the electrolytic polishing time is too short and continuous feeding and discharging cannot be realized. Meanwhile, after the whole polishing process is completed, one electrolyte in each container must be manually poured out by an operator, and then the electrolyte is manually conveyed to the next cleaning station by the operator. The long contact of the operator with the electrolyte can cause certain damage to the health of the operator.

The applicant points out that when the prior art, such as the multi-channel continuous electrolytic polishing device and polishing method with the subject name of "metal base belt" (publication number CN102851729A) and the prior art with the subject name of "an electrolytic polishing device" (publication number CN203683716U), is used for electrolytic polishing of a cup body (i.e., a workpiece) with an opening, the workpiece in an electrolytic polishing tank can only be integrally subjected to electrolytic polishing, and after the electrolytic polishing process is finished, the electrolytic rod and the cup body need to be integrally and completely separated to perform the loading and unloading operation of the workpiece, so that the electrolytic polishing device in the prior art has the problem that the electrolytic polishing time of the workpiece is too short.

In view of the above, there is a need for an improved electropolishing apparatus in the prior art to solve the above-mentioned problems.

Referring to fig. 13, in the present embodiment, the electrolytic rod 70 vertically penetrates the first liquid supply casing 53, the fixing base 20 for fixing the electrolytic rod 70 is disposed below the lower disk 52, and the cathode 209 is disposed below the fixing base 20. A flange ring 206, a lock nut 208 nested on the flange ring 206, and a gland 207 nested between the lock nut 208 and the flange ring 206 are disposed in the longitudinal direction between the cathode 209 and the first liquid supply case 53. The bottom of the locking nut 208 is provided with a cathode 209.

The guiding separation area is formed by a convex part configured on the circular column 15, the rolling mechanism 43 makes a circular motion along the annular end surface formed on the top of the circular column 15, and at least more than two anode devices 60 are formed in a state of being longitudinally separated from the bottom of the cup body 30 when transversely crossing the convex part. Specifically, in this embodiment, at least one anode assembly 60 is formed to be longitudinally separated from the cup 30 when the base is rotated one turn. The guiding separation area is formed by a convex part 150a configured by the circular column 15, and the top of the convex part 150a forms at least two anode devices 60 which are longitudinally separated from the bottom of the cup 30. The projection 150a is formed of at least two linear guide edges. The number of the anode assembly 60 longitudinally separated from the cup 30 depends on the number of the bosses 150 a. A protrusion portion forming a guide separation region; similarly, the two protrusions may form two guiding and separating areas.

The protrusion 150a is formed of at least two linear guide edges or one curved guide edge forming a height difference in the vertical direction. For example, the protrusion 150a may be composed of a linear guide edge 1501, a linear guide edge 1502, and a linear guide edge 1503. The rolling mechanism 43 rolls in translation on the linear guide edge 153 during the horizontal rotation of the base, in particular during the pressing of the anode plate 61 against the cup 30 and the continuous electrolytic polishing. At this time, the slide block 42 does not move in the vertical direction. Specifically, as shown in fig. 4 and 7, the anode plate 61 is at the position of the anode plate 61a, and the slide block 42 is at the position of the slide block 42 a.

With further rotation of the drive mechanism, the rolling mechanism 43 moves laterally across the inflection point 1 and along the linear guide edge 1501, and in the process the slide block 42 in fig. 4 slides upward along the guide mechanism 40 to the position of the slide block 42b, and in the process the anode plate 61 moves upward from the position of the anode plate 61a to the position of the anode plate 61b, so that the anode plate 61 and the bottom of the cup 30 are separated from each other. The operator can pull the cup body 30 out of the positioning seat 511, the electrolyte inside the cup body 30 automatically drops down to the liquid storage tank 17, and the operator is effectively prevented from contacting the toxic and harmful electrolyte. The electrolytic rods 70 are kept in synchronous motion with the cup 30 during the horizontal rotation of the base, and are all in a vertical posture.

With the further rotation of the driving mechanism, the operator can manually or by means of a robot arm automatic feeding manner, sleeve the cup body 30 to be electropolished on the electrolytic rod 70 with the cup mouth facing downward, and reinsert it into the positioning seat 511. Therefore, in the present embodiment, preferably, the straight guide edge 1502 can always keep the two anode plates 61 longitudinally separated from the bottom of the cup 30, so as to continuously perform the loading and unloading operations of the cup 30. So that at least two or more anode assemblies 60 are formed at the top of the boss in a state of being longitudinally separated from the bottom of the cup 30.

With further rotation of the drive mechanism, the rolling mechanism 43 moves laterally across the inflection point 3 and along the linear guide edge 1503, and in the process the slide block 42 in fig. 4 slides down the guide mechanism 40 up to the position of the slide block 42a, and in the process the anode plate 61 moves down from the position of the anode plate 61b to the position of the anode plate 61a, so that the anode plate 61 is in longitudinal contact with the bottom of the cup 30.

Finally, with further rotation of the drive mechanism, the rolling mechanism 43 laterally crosses the inflection point 4 and begins to enter a translational attitude. At this time, the lip 304 of the cup 30 contacts the sealing member 54 and is closely attached to and contacts the sealing member 54 by the longitudinal clamping action of the anode plate 61. Then, the electrolytic solution is pumped into the cup 30 again through the annular through hole 541, and the electrolytic polishing process is started. When the rolling mechanism 43 laterally crosses the inflection point 4, the rolling mechanism 43 contacts the vertically lower linear guide edge 152, and the linear guide edges 153 are connected end to the linear guide edge 152 at the same height.

Meanwhile, the linear guide edge 152, the linear guide edge 1501, the linear guide edge 1502, the linear guide edge 1503 and the linear guide edge 152 in this embodiment are connected end to end in a top view to form an annular end surface for the rolling mechanism 43 to perform a circular motion. Meanwhile, linear guide edge 152, linear guide edge 1501, linear guide edge 1502, linear guide edge 1503 and linear guide edge 152 are formed from the perspective of the three-dimensionally configured circular column 15 after deployment.

The rolling mechanism 43 is lifted or lowered by the protrusion 150a while making a circular rolling motion on the annular end surface, so as to drive the entire anode assembly 60 to perform a lifting and lowering motion in the longitudinal direction, thereby achieving a longitudinal separation and a longitudinal contact between the anode plate 61 of the anode assembly 60 and the bottom of the cup 30 in the pilot separation region. Meanwhile, when the rolling mechanism 43 performs a circular rolling motion on the annular end surface, the anode device 60 and the circle of downward-opening cup 30 embedded in the radial outer side of the base in an annular shape rotate synchronously and are arranged in parallel. The ring of cup bodies 30 are distributed in a radial annular shape at equal intervals.

It should be noted that the convex portion 150a may also be composed of a linear guiding edge 1501 and a linear guiding edge 1503, so that the convex portion is configured to be triangular or any other shape as long as the convex portion can lift and lower the rolling mechanism 43 during the rotation of the base, so that the anode plate 61 in the guiding separation area sequentially contacts and separates from the bottom of the cup 30 along the longitudinal direction. Whether the base rotates clockwise or counterclockwise, the core purpose of the invention can be achieved.

Meanwhile, in the embodiment, the DC power used for the electrolytic polishing is 5-20V. The treatment time of the whole electrolytic polishing is 60-480 seconds, and the electrolytic polishing current is 30-100A. The entire electropolishing time is the time required to rotate in the non-conductive separation area with the cup 30 inserted longitudinally with the electrolytic rod 70 and ensuring that the interior of the cup 30 is filled with the electrolyte, and thus, the time required to rotate each cup 30 in the non-conductive separation area is equal. Meanwhile, the applicant also indicates that the treatment time of the electrolytic polishing performed on the inner wall surface of each cup 30 can be arbitrarily adjusted according to the process requirements by increasing or decreasing the rotation speed of the driving unit 12, thereby improving the adaptability of the rotary type electrolytic apparatus in performing the electrolytic polishing by adopting different electrolytic polishing times for the actual situation of the surface of workpieces such as different cups 30.

Meanwhile, in this embodiment, the driving unit 12 may adopt a servo motor or a stepping motor, and may adopt a PLC or a single chip to control the driving mechanism, and may adopt an upper computer to connect a plurality of rotary electrolyzers and their affiliated controlled devices through an industrial control bus based on a MODBUS protocol or a UART interface, thereby implementing centralized batch intelligent production.

Referring to fig. 8, as a reasonable variation of the present embodiment, compared to the example shown in fig. 7, the guiding separation area is formed by a protrusion 150b configured by the circular column 15, and the top of the protrusion 150b forms at least two anode devices 60 longitudinally separated from the bottom of the cup 30. The projection 150b is formed by a curved guide edge 1504 having a height difference in the vertical direction. At this time, the protrusion 150b may be semi-circular or semi-elliptical so that the rolling mechanism 43 achieves longitudinal separation and contact of the anode plate 61 with the bottom of the cup 30 during movement on the curved guide edge 1504.

In this embodiment, invert cup 30 and upwards pour into electrolyte into through hollow electrolysis stick 70 with electrolyte, thereby realized the infiltration and the contact degree to the internal face of work piece such as cup 30 with electrolyte, effectively prevented that the internal face from appearing the bubble when electrolytic polishing, improved the electrolytic polishing effect, and improved electrolytic polishing's degree of automation and production efficiency, especially through the ring post 15 that forms a guide separation zone, not only realized the continuous electrolytic polishing to a plurality of annular pivoted cups 30, and can only realize cup 30's unloading and material loading operation in proper order in the guide separation zone, solved the electrolytic polishing time that traditional electrolytic polishing equipment exists too short and can't realize the technical problem of unloading in succession.

Secondly, in the present embodiment, the opening of the cup 30 is disposed downward, and when the operator takes the electropolished cup 30, the electrolyte automatically drops downward into the liquid storage tank 17, and since the electrolyte only contacts the inner wall surface of the cup 30, the harm of the toxic and harmful electrolyte to the operator is significantly reduced. In the rotation process of the base, the circle of cup bodies 30 driven by the base can continuously perform the electrolytic polishing operation, so that the treatment efficiency of electrolytic polishing is improved, and the occupied area of the rotary electrolytic device is remarkably reduced.

The electrolyte flows into the annular channel formed by the electrolytic rod 70 and the vent pipe 80 from the lateral through hole 81 and flows upward, and the electrolyte inside the cup 30 is re-introduced downward into the liquid storage tank 17 through the vent pipe 80.

As shown in fig. 14 to 16, in the present embodiment, in order to prevent air from accumulating at the bottom of the cup 30 and sufficiently exhausting the air, the top of the air pipe 80 extends in the vertical direction over the top of the electrolytic rod 70.
