Description

Rotary type electrolytic polishing equipment

Technical Field

The invention relates to the technical field of electrolytic polishing, in particular to rotary electrolytic polishing equipment.

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 a low resistance at the raised portion and a high current density, which causes the raised portion to dissolve faster than the recessed portion. 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. When the prior art, such as the multi-channel continuous electrolytic polishing device and the polishing method with the subject name of metal base belt (publication No. CN102851729A) and the prior art with the subject name of an electrolytic polishing device (publication No. CN203683716U), performs electrolytic polishing on a cup body (i.e. a workpiece) with an opening, workpieces in an electrolytic polishing tank can only be integrally subjected to electrolytic polishing, and after the electrolytic polishing process is finished, an electrolytic rod and the cup body need to be integrally and completely separated to perform feeding and discharging operations on the workpieces, so that the electrolytic polishing time of the workpieces is too short in the prior art.

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

The electrolytic rod 54 in the non-guiding separation area is always kept inserted into the cup body 30, and continuously and uninterruptedly electrolytic polishing treatment is performed on a plurality of cup bodies 30 in the ring-shaped workpiece positioning seat 20.

In the embodiment shown in fig. 4, the guiding separation area refers to the ring segment where the bracket M is located, and the ring segment where the bracket M is removed forms the non-guiding separation area. The drive mechanism is disposed in a region 144 enclosed by the inner annular wall 105. In the non-guide separation region, the electrolytic rod 54 is always inserted into the cup 30 and the electrolytic polishing process is continuously performed.

The applicant has pointed out that the treatment time of the electropolishing of each cup 30 can be arbitrarily adjusted according to the process requirements by increasing or decreasing the rotation speed of the drive unit 12, thereby significantly increasing the adaptation of the apparatus to the actual use of different electropolishing times for different workpiece surfaces and to the suitability of the apparatus for performing the electropolishing.

As shown in fig. 15, a vertically arranged pillar 44 and a reinforcing plate 41 vertically arranged with respect to the pillar 44 are disposed radially inside the vertical rail 401, the reinforcing plate 41 and the pillar 44 are connected to a base 42, and the base 42 is fixedly connected to the lower disk 52. The base 42 is provided with four mounting holes 45 for passing through the mounting holes 45 by bolts 46 and threadedly secured to blind holes (not shown) provided in the lower disc 52.

Specifically, in the present embodiment, the apparatus includes twenty-four guiding mechanisms 40 and twenty-four workpiece positioning seats 20 in a matched number, and each workpiece positioning seat 20 is slidably connected to one guiding mechanism 40 through a sliding block 21. The guide mechanism 40 is vertically disposed. A sliding member 421 is disposed between the vertical rail 401 and the sliding block 21, and the sliding member 421 may be a ball or a sliding rail. The sliding block 21 includes a sliding base 211, a vertical plate 22 extending vertically downward from the sliding base 211, a rolling mechanism 24 is disposed at a terminal of the vertical plate 22, the rolling mechanism 24 may be a bearing, and the rolling mechanism 24 rolls on a circular track 181 formed at the top of the circular column 113 (i.e., a circular end surface formed at the top of the circular column 113). The rolling mechanism 24 is assembled with the vertical plate 22 through a rotation shaft 23 arranged in the transverse direction. Meanwhile, the workpiece positioning seat 20 is connected with a connecting arm 212 which is vertically extended downwards from the sliding base 211, and the workpiece positioning seat 20 is vertically arranged with the connecting arm 212.

The circular column 113 is a solid body with a certain thickness (along the radial direction), and is vertically disposed above the inner annular wall 105, and at least one notch portion 200 is disposed along the circumferential direction of the circular column 113 to form a guiding separation area, the workpiece positioning seat 20 is slidably connected to the guiding mechanism 40 through the sliding block 21, the notch portion at least forms a first guiding edge 116 for longitudinally separating the cup 30 and the electrolytic rod 54, and a second guiding edge 118 for longitudinally inserting, the electrolytic rod 54 is annularly and vertically disposed below the upper circular disc 51, and is coaxially disposed with the opening of the cup 30, and the opening of the cup 30 is upward. The annular column 113 and the inner annular wall 105 may be regarded as two components disposed one above the other or as a whole.

The guiding mechanism 40 is vertically arranged at the edge of the lower circular disc 52, and drives the rolling mechanism 24 to make a circular motion on an annular end surface formed at the top of the circular column 113 along with the rotation of the lower circular disc 52, and the height of the workpiece positioning seat 20 is lowered along the first guiding edge 116 in a passive manner when the workpiece positioning seat transversely spans the notch portion, so as to separate the cup 30 from the electrolytic rod 54 longitudinally; the workpiece positioning seat 20 passively elevates the height of the workpiece positioning seat 20 along the second guiding edge 118 while laterally spanning the notched portion to longitudinally insert the cup 30 into the electrolytic rod 54. The thickness of the circular column 113 is at least larger than the width of the rolling mechanism 24 to provide good support for the rolling mechanism 24 and prevent the rolling mechanism 24 from falling off during rotation. Preferably, in the present embodiment, a ring of flanges (not shown) or two rings of flanges (not shown) may be further provided at the radially outer side of the top of the circular column 113 to provide a good guiding effect for the rolling mechanism by the ring or two rings of flanges. The notch 200 is defined by the first guide edge 116, the bottom flat edge 117, and the second guide edge 118. In particular, in the present embodiment, the "bottom straight edge 117" and the "straight" features in the "bottom straight edge 122", "top straight edge 117 a", "straight edge 115", "straight edge 119", and "straight edge 139" mentioned below refer to the perspective formed by the unfolded circular ring column 113 having a three-dimensional structure in three-dimensional space.

The plurality of workpiece positioning seats 20 and the plurality of electrolytic rods 54 are arranged in a circular shape (in a top view angle), and are synchronously rotated in the same direction along with the upper disc 51 and the lower disc 52 in the horizontal direction, so that the insertion and the separation in the longitudinal direction are realized, when the electrolytic rods 54 are inserted into the opening of the cup body 30, electrolytic polishing is performed, and when the electrolytic rods 54 are pulled out of the opening of the cup body 30, the electrolytic polishing is stopped. In this application, the term "Longitudinal direction"means in the vertical direction, and"Transverse direction"refers to the horizontal direction. During electropolishing, the cup 30 needs to be filled with electrolyte. When the opening of the cup body 30 is upward, the electrolyte can be injected into the cup body 30 with the upward opening by an external manipulator (not shown) provided with a pipeline for adding the electrolyte to the opening of the cup body 30, and the electrolyte can be ensured to fully infiltrate the inner wall surface of the cup body 30, so that the inner wall surface of the cup body 30 is prevented from generating local vacuole and white bubbles in the electrolytic polishing processPoor electrolysis such as spots.

In the present embodiment, the guiding and separating area at least forms more than two electrolytic rods 54 and the cup 30 in a longitudinally separated state, as shown in fig. 3. The number of the state in which the lead separating area is formed in which the electrolytic rod 54 is longitudinally separated from the cup 30 depends on the slopes of the first and second guide edges 116 and 118 or the lateral length of the bottom flat edge 117. Meanwhile, the distance of the relative movement between the electrolytic rod 54 and the cup 30 in the vertical direction in the pilot separation area is greater than the distance of the vertical insertion of the electrolytic rod 54 into the cup 30.

Meanwhile, referring to fig. 3 and 9, when the workpiece positioning seat 20 suspended by the ring of the guiding mechanisms 40 uniformly distributed at equal intervals moves circularly in the waste liquid tank 100 in a circular ring shape in fig. 4, and passes through the guiding separation region in sequence, the workpiece positioning seat 20 is in a state of an arrow 311, a state of an arrow 321, and a state of an arrow 331 in sequence. The workpiece positioning seat 20 is formed in a state that the arrow 331 is located, two electrolytic rods 54 are longitudinally separated from the cup body 30, and in the process, the rolling mechanism 24 rotates along the bottom straight flat edge 117 along the same horizontal plane.

During the process of guiding the workpiece positioning seat 20 to move up and down in the separation area, the vertical rail 401 does not move longitudinally in the vertical direction, when the rolling mechanism 24 rolls on the circular rail 181 formed at the top of the circular column 113, the rolling mechanism 24 moves along the flat edge 115 in the direction shown by the arrow D, and when the workpiece positioning seat transversely crosses over the inflection point 1, the rolling mechanism 24 contacts with the first guiding edge 116. At this time, the four upwardly open cups 30 accommodated in the workpiece positioning socket 20 move downward under the action of gravity, and the driving mechanism still drives the upper disc 51 and the lower disc 52 to rotate continuously. The rolling mechanism 24 then continues to roll down the first guide edge 116 and laterally across the inflection point 2 and into the bottom straight edge 117.

Referring to fig. 3, the electrolytic rod 54 is completely separated from the cup 30 in the longitudinal direction and the longitudinal distance between the electrolytic rod and the cup is maximized. The operator can take the cup 30 after the electrolytic polishing out of the workpiece positioning seat 20 to complete the blanking operation. Then, the operator loads the cup 30, which has not been subjected to electrolytic polishing, forward in the workpiece positioning seat 20, which is also located on the bottom flat edge 117, to complete the loading operation of the cup 30. Then, as the upper disc 51 and the lower disc 52 further rotate in the direction of arrow D, the rolling mechanism 24 rolls upwards across the inflection point 3 in the direction of arrow D and enters the second guiding edge 118, and since the four integrally assembled electrolytic rods 54 are also synchronously rotated by the upper disc 51, the four electrolytic rods 54 are gradually and correspondingly inserted into the four cups 30 longitudinally during the rolling process of the rolling mechanism 24 on the second guiding edge 118, and electrolysis is started. Finally, after the rolling mechanism 24 has crossed the inflection point 4 in the lateral direction indicated by the arrow D, the electrolytic rod 54 is inserted to the bottom in the longitudinal direction and continues to rotate in the direction indicated by the arrow D, at which time the rolling mechanism 24 comes into contact with the flat edge 119. The straight right side 129 of fig. 9 is joined end to end with the straight left side 115 and forms a circle.

In the present embodiment, it is preferable that two workpiece positioning seats 20 are always held in the circular arc section corresponding to the bottom straight flat edge 117, but only one workpiece positioning seat 20 may be held. The applicant has pointed out that the longitudinal separation of the electrolytic rods 54 from the opening of the cup 30 at the level of the horizontal line E is possible only if the rolling mechanism 24 rolls on the first guide edge 116 and the second guide edge 118, as far as the position where the longitudinal separation between the electrolytic rods 54 and the cup 30 occurs is formed between the first guide edge 116 or the bottom flat edge 117 or the second guide edge 118. Meanwhile, the circular column 113 and the inner annular wall 105 may also be an integrated structure, and the circular column 113 is disposed above the inner annular wall 105. The flat side 115, the first guide side 116, the bottom flat side 117, the second guide side 118, the flat side 119 and the flat side 129 are connected end to end in sequence in a top view to form a circular track 181 formed by the top of the circular column 113 in fig. 4. In the present embodiment, when the rolling mechanism 24 performs the circular rolling along the annular end surface formed at the top of the circular column 113, the rolling mechanism 24 performs the circular rolling along the circular track 181.

The rotary type electrolytic polishing apparatus further comprises: the housing 107, the top of the housing 107 is provided with at least one exhaust suction port 175 for extracting exhaust gas. The shell 107 partially covers the driving mechanism, the upper disc 51, the lower disc 52, the plurality of workpiece positioning seats 20 and the electrolytic rods 54 (or the electrolytic rods 54a) which coaxially and synchronously rotate. The exhaust suction port 175 is connected to a suction device (not shown) through a pipe (not shown) to discharge toxic and harmful exhaust gases generated during continuous rotary electropolishing of the apparatus, so as to ensure that air in the operating area of the apparatus does not harm the health of the operator.

The driving mechanism is positioned at the center of the whole rotary type electrolytic polishing device and is positioned on the base 11 below the lower disc 52, and the shell 107 is connected with the base 10 to enclose and shield the components such as the upper disc 51, the lower disc 52, the waste liquid groove 100 and the like. The housing 107 may be made of stainless steel.

As shown in fig. 9, 16 and 17, in the present embodiment, the guiding and separating area is formed by the notch 200, and at least two or more electrolytic rods 54 are formed at the bottom of the notch in a state of being separated from the cup 30 in the longitudinal direction. The number of the notch portions may be one, two, or more.

As a reasonable variation of the apparatus disclosed in this embodiment, the circular column 113 is provided with two notches, i.e. the notch 200 and the notch 300, in the circumferential direction to form two guiding and separating areas, i.e. the circular ring area where the bracket M is located and the circular ring area where the bracket N is located. The notch 300 is defined by the first guide edge 121, the bottom flat edge 122, and the second guide edge 123. In fig. 17, the notch 300 is similar to the notch 200, and includes

inflection points

5, 6, 7, and 8. When the lower disc 52 rotates horizontally, after the rolling mechanism 24 transversely crosses the notch 200 on the circular track 181 in the direction indicated by the arrow D, it transversely crosses the notch 300 again, the rolling mechanism 24 provided at the bottom of each guiding mechanism 40 transversely crosses the notch 300 again in the same manner, and the longitudinal insertion and separation of the electrolytic rod 54 and the cup body 30 are performed again, and the loading and unloading operations of the cup body can be sequentially realized in the guiding separation area formed by the notch 300. The straight edge 124 in fig. 17 is joined end to end with the straight edge 115. The flat edge 115, the first guide edge 116, the bottom flat edge 117, the second guide edge 118, the flat edge 119, the flat edge 129, the first guide edge 121, the bottom flat edge 122, the second guide edge 123 and the flat edge 124 are sequentially connected end to end in a top view, and also form a circular track 181 formed by the top of the circular column 113 in fig. 4.

Therefore, two operators or robots can respectively carry out the blanking and the loading of the cup body 30, thereby further improving the production efficiency of the electrolytic polishing carried out by the equipment.

In the embodiment, the workpiece positioning seat 20 arranged in the circular ring shape can realize continuous electrolytic polishing treatment in the circular waste liquid tank 100, and only sequentially realize the discharging and feeding operations of the cup body 30 in the guiding and separating area, thereby solving the technical problems that the electrolytic polishing time is too short and continuous discharging and feeding cannot be realized in the electrolytic polishing equipment in the prior art. Of course, the loading and unloading operation of the cup 30 in the guiding and separating area can be performed manually or by a robot.

Example two:

this embodiment discloses a first modification of the rotary type electrolytic polishing apparatus of the present invention.

As shown in fig. 19 to fig. 21, the main difference of the rotary type electropolishing apparatus disclosed in this embodiment is that, in this embodiment, the circular column 113 is vertically disposed on the inner annular wall 105, and at least one notch portion 200 is opened along the circumferential direction of the circular column 113 to form the guiding and separating area, the notch portion at least forms a first guiding edge 116 for longitudinally separating the cup 30 and the electrolytic rod 54a and a second guiding edge 118 for longitudinally inserting, the electrolytic rod 54a is annularly and vertically upward disposed in the waste liquid tank 100, the electrolytic rod 54a is slidably connected with the guiding mechanism 40 through the sliding block 21, the workpiece positioning seat 20 is annularly and vertically disposed below the upper circular disc 51, and the cup 30 is embedded into the workpiece positioning seat 20 with an opening downward posture. The electrolytic rod 54a is hollow, and the electrolytic rod 54a has openings at both ends, and the electrolyte is sprayed into the cup 30 vertically upward from the opening 541 at the top of the electrolytic rod 54 a.

The guiding mechanism 40 is vertically arranged at the edge of the lower circular disc 52, and drives the rolling mechanism 24 to make a circular motion on an annular end surface formed at the top of the circular column 113 along with the rotation of the lower circular disc 52, and the workpiece positioning seat 20 lowers the height of the electrolytic rod 54 along the first guiding edge 116 in a passive manner when transversely crossing the notch portion, so as to longitudinally separate the cup 30 from the electrolytic rod 54 a; the workpiece positioning seat 20 passively elevates the height of the electrolytic rod 54a along the second guiding edge 118 while laterally spanning the cutaway portion to longitudinally insert the electrolytic rod 54a into the cup 30.

Specifically, in the present embodiment, the workpiece positioning seat 20 can be formed by welding slender stainless steel bars, and the bottom of the workpiece positioning seat is hollowed to form four holes 217, and the cup mouth portion 307 with external threads formed at the cup mouth of the cup body 30 can be inserted into the hole 217 of the workpiece positioning seat 20 and be embedded into the workpiece positioning seat 20 in a downward opening posture. The apparatus disclosed in this embodiment is the same as the apparatus disclosed in the first embodiment, and the positions of the workpiece positioning seat 20 and the electrolysis rod 54a are interchanged, so that the cup 30 only performs the circular translational motion in the horizontal direction, and the electrolysis rod 54a does not only perform the circular translational motion in the horizontal direction, and sequentially performs the descending motion and the ascending motion, or sequentially performs the descending motion, the translational motion and the ascending motion in the guide separation region formed by transversely crossing the notch portion 200, thereby performing the longitudinal insertion and separation of the electrolysis rod 54a and the cup 30, and sequentially performing the blanking and the loading operations of the cup 30 in the guide separation region formed by the notch portion 300. The electrolytic rod 54a also simultaneously performs circular translational motion during the descending motion and the ascending motion in sequence, and during the descending motion, the translational motion and the ascending motion in sequence; and the circular translational movement performed by the electrolytic rod 54a is kept synchronized with the circular translational movement of the cup 30.

Referring to fig. 19, in this embodiment, the lip 303 of the cup 30 is pressed against the seal member 204. The sealing ring 204 is sleeved on the outer side of the electrolytic rod 54a, and an annular through hole 205 is formed between the sealing ring and the electrolytic rod 54a, so that the internal cavity 302 of the cup 30 and the return pipe 203 establish a flow passage of the electrolyte through the annular through hole 205. Meanwhile, the return pipe 203 is connected to the return pipe 203, and a circulation pump (not shown) is connected to the return pipe 203 to provide power for circulating the electrolyte 81 through the circulation pump, and the circulation pump pumps the electrolyte again into the hollow electrolytic rod 54a from the opening at the bottom of the electrolytic rod 54a and drives the electrolyte to flow upward, and the cup opening of the cup 30 is sealed by the sealing ring 204. In this embodiment, the circulating pump is 40 CQ-20. The arrow flow direction in fig. 19 shows the flow direction of the electrolyte.

When the electrolytic rod 54a is conveyed upward and ejects the electrolyte from the top opening 541, bubbles of the inner wall surface of the cup 30 can be taken into the waste liquid tank 100 along the annular through hole 205 by the electrolyte, and eventually the electrolyte collected in the waste liquid tank 100 flows back into the liquid tank 109 through the pipe. The return tank 109 may be provided with a bubble separator (e.g., a bubble remover) to remove excess air or bubbles from the return tank 109 and pump the electrolyte up the bottom opening of the electrolytic rod 54a by the circulation pump.

Meanwhile, in the present embodiment, the bottom of the return pipe 203 is further provided with a flange ring 206, a lock nut 208 nested on the flange ring 206, and a sealing sleeve 207 nested between the lock nut 208 and the flange ring 206. The bottom of the locking nut 208 is provided with a cathode 209.

Note that, in order to further simplify the structure, the cathode 209 may be omitted and the metal return pipe 203 may be used as the cathode, and in this case, the return pipe 203 must be made of a metal having good electrical conductivity. Meanwhile, the bottom of the cup 30 is ensured to contact the anode 33, and a fixedly arranged anode is arranged in each guiding mechanism 40, and a rotary current collecting device 60 and a conductive plate 61 similar to those in the first embodiment can be adopted to electrically connect with the anode 33. The anode 33 may be made of copper plate or other metal with good conductivity.

Please refer to the embodiment a, and detailed description thereof is omitted here for the technical solutions of the same parts of the rotary electropolishing apparatus disclosed in this embodiment as those in the embodiment a.

Example three:

this embodiment discloses a second modification of the rotary type electrolytic polishing apparatus of the present invention.

Referring to fig. 18, the rotary type electropolishing apparatus disclosed in this embodiment is different from the rotary type electropolishing apparatus disclosed in the first and/or second embodiments in that, in this embodiment, the guiding separation region is formed by a protrusion, and at least two or more electrolytic rods 54 are formed at the top of the protrusion in a longitudinally separated state from the cup 30.

The guide mechanism 40 is vertically arranged between the upper disc 51 and the lower disc 52, the guide mechanism 40 is connected with the lower disc 52, at least one protruding part is arranged along the circumferential direction of the circular column 113 to form the guide separation area, the electrolytic rod 54 is connected with the guide mechanism 40 in a sliding mode through the sliding block 21 and is vertically arranged downwards, the protruding part at least forms a third guide edge 116a used for longitudinally separating the cup body 30 and the electrolytic rod 54 and a fourth guide edge 118a used for longitudinally inserting, the electrolytic rod 54 is annularly vertically arranged below the upper disc 51 and is coaxially arranged with the opening of the cup body 30, and the opening of the cup body 30 is upward. The cup 30 is placed in the workpiece positioning seat 20 in an open-top manner in the posture as shown in fig. 6 or 7.

The circular column 113 is vertically arranged on the inner annular wall 105, and drives the rolling mechanism 24 to make circular motion on the annular end surface formed at the top of the circular column 113 along with the rotation of the lower disc 52, when the electrolytic rod 54 transversely crosses the convex part, the height of the electrolytic rod 54 is increased along the third guiding edge 116a in a passive mode, and the electrolytic rod 54 is vertically pulled out of the cup body 30; the electrolysis rod 54 is passively lowered along the fourth leading edge 118a along the height of the charged electrolysis rod 54 as it traverses the boss to insert the electrolysis rod 54 longitudinally into the cup 30.

When a circle of workpiece positioning seats 20 suspended by the guide mechanisms 40 which are uniformly distributed at equal intervals in a ring shape move circularly in the waste liquid tank 100 which is in a ring shape in fig. 4 and sequentially passes through the guide separation region, the vertical tracks 401 do not move vertically in the process of guiding the up-and-down movement in the separation region by the workpiece positioning seats 20, when the rolling mechanisms 24 roll on the ring-shaped tracks 181 formed at the top of the circular columns 113, the rolling mechanisms 24 respectively move along the flat edges 115 in the directions shown by the arrows D, and when the workpiece positioning seats transversely cross over the inflection point 1, the rolling mechanisms 24 are in contact with the third guide edges 116 a. The four electrolytic rods 54 suspended below the conductive plate and vertically disposed are moved upward in the longitudinal direction, and finally the electrolytic rods 54 are longitudinally pulled out from the opening of the cup body 30 to achieve the longitudinal separation of the electrolytic rods 54 from the cup body 30. The rolling mechanism 24 then continues to roll up the third guide edge 116a and laterally across the inflection point 2a and into the top flat edge 117 a. Meanwhile, a top flat side 117a higher than the flat side 115 is formed between the third guide side 116a and the fourth guide side 118a, and the conductive rod 54 rotates in a translational posture at the stage of the top flat side 117 a. At this time, the electrolytic rod 54 is completely longitudinally separated from the cup 30 with the longitudinal distance therebetween being the maximum. The operator can take the cup 30 after the electrolytic polishing out of the workpiece positioning seat 20 to complete the blanking operation. Then, the operator loads the cup 30, which has not been subjected to electrolytic polishing, forward one of the workpiece positioning seats 20, which is also located on the top flat edge 117a, to complete the loading operation of the cup 30. Then, as the upper disc 51 and the lower disc 52 further rotate in the direction of the arrow D, the rolling mechanism 24 rolls downwards across the inflection point 3a and enters the fourth guiding edge 118a in the direction shown by the arrow D, and since the four groups of integrally assembled electrolytic rods 54 are also synchronously rotated by the upper disc 51, the four electrolytic rods 54 are gradually and correspondingly inserted into the four cups 30 longitudinally during the rolling process of the rolling mechanism 24 in the fourth guiding edge 118a, and the electrolysis is started. Finally, after the rolling mechanism 24 has crossed the inflection point 4a in the lateral direction indicated by the arrow D, the electrolytic rod 54 is inserted to the bottom in the longitudinal direction and continues to rotate in the direction indicated by the arrow D, at which time the rolling mechanism 24 comes into contact with the flat edge 119. The straight edge 139 on the right side of fig. 18 is joined end to end with the straight edge 115 on the left side and forms a circle. In the present embodiment, it is preferable that two workpiece positioning seats 20 are always held in the circular arc section corresponding to the top flat straight edge 117a, but only one workpiece positioning seat 20 may be held.
