Description

Technical Field

[0001] The invention relates to the technical field of galvanized sheet preparation, and in particular to a passivation device and process for preparing galvanized sheet. Background Art

[0002] Galvanized sheet is widely used in many fields such as construction, home appliances, automobile manufacturing, aerospace, etc. due to its excellent corrosion resistance and low cost. Passivation treatment is a key step to improve the corrosion resistance of galvanized sheet. By forming a dense passivation film on the surface of the zinc layer, the corrosion resistance of the galvanized sheet can be significantly improved and its service life can be extended.

[0003] The existing galvanized sheet passivation device mainly adopts a clamping and fixing method to fix the galvanized sheet and then put it into the passivation solution. However, when preparing corrugated galvanized sheet, due to the characteristics of the corrugated sheet, when fixing the corrugated sheet, it is necessary to clamp and fix the relatively flat area of ​​the corrugated sheet (i.e. the junction of the crests and troughs) to reduce damage to the corrugated sheet. Therefore, when fixing the corrugated sheet, it is necessary to accurately find the relatively flat area of ​​the corrugated sheet to reduce the impact on the shape of the corrugated sheet. However, for different batches of corrugated sheets, the position of the fixing jaws needs to be adjusted again, which results in a large workload, a lot of time consumption and low production efficiency. Summary of the invention

The second elastic member between the transfer plate 18 and the first sliding member 10 is set as a spring, which is used to provide continuous thrust to the first sliding member 10.

[0061] See also Figure 2 , Figure 3 , Figure 5-Figure 7 , Fig.10 and Fig.11, further comprising: a second electric push rod 19, fixedly connected to the support plate 5, a connecting rod 20 fixedly connected to the telescopic end of the second electric push rod 19, a third sliding plate 21 slidably connected to the first sliding plate 6, the third sliding plate 21 and the connecting rod 20 limited sliding cooperation, the L-shaped frames 7 on the same first sliding plate 6 are divided into a group of two, and the third sliding plate 21 is provided with a sliding groove with the same number as the group of L-shaped frames 7 on the adjacent first sliding plate 6; a first extrusion block 22, the number of which is the same as the group of L-shaped frames 7 on the adjacent first sliding plate 6, fixedly connected to one side of the sliding groove of the third sliding plate 21 A second extrusion block 23 is slidably connected in the slide groove of the third sliding plate 21, the first extrusion block 22 is extruded and matched with the adjacent second extrusion block 23, the first extrusion block 22 is fixedly connected with an elastic telescopic rod 24, the second extrusion block 23 is fixedly connected to the telescopic end of the adjacent elastic telescopic rod 24, the first extrusion block 22 and the adjacent second extrusion block 23 are respectively extruded and matched with the two second sliding members 17 in the adjacent group of L-shaped frames 7, and the sum of the lengths of the first extrusion block 22 and the adjacent second extrusion block 23 is less than the length of the distance between the two second sliding members 17 in the same group of L-shaped frames 7.

[0062] In the above scheme, a through hole is provided on the third sliding plate 21, and the connecting rod 20 passes through the through hole on the third sliding plate 21 and slides with it. The first extrusion block 22 and the second extrusion block 23 are both set to a right-angled trapezoid. The inclined surface of the first extrusion block 22 is extruded and matched with the second sliding member 17, and the upper bottom surface of the first extrusion block 22 is extruded and slidably matched with the second sliding member 17. The inclined surface of the second extrusion block 23 is extruded and matched with the second sliding member 17, and the upper bottom surface of the second extrusion block 23 is extruded and slidably matched with the second sliding member 17. The elastic telescopic rod 24 is initially in a contracted state, and the elastic telescopic rod 24 is used to drive the second extrusion block 23 to reset.

[0063] When the present device is needed to perform a passivation operation on the corrugated plate, the staff will place the corrugated plate to be passivated between the two second sliding plates 11, and then start the first electric push rod 14 to extend the telescopic end of the first electric push rod 14, and synchronously drive the second sliding plate 11 and the parts thereon and the first sliding plate 6 and the parts thereon to move in a direction close to the corrugated plate through the connecting piece 15. During the movement of the second sliding plate 11, some sliding columns 12 on the second sliding plate 11 first contact the wave crests on the corrugated plate and are pushed by the wave crests on the corrugated plate, so that the sliding columns 12 slide on the second sliding plate 11, and then the second sliding plate 11 continues to move, and all the sliding columns 12 are gradually blocked by the corrugated plate and slide on the second sliding plate 11. After all the sliding columns 12 are in contact with the corrugated plate, the first electric push rod 14 is closed. At this time, the sliding columns 12 away from the side of the corrugated plate together form a shape consistent with the bending amplitude of the corrugated plate. During the movement of the first sliding plate 6, the third sliding plate 21 thereon slides along the connecting rod 20.

[0064] During the movement of the sliding column 12, the side of the sliding column 12 away from the corrugated plate contacts and squeezes the rotating plate 8, causing the rotating plate 8 to gradually rotate. During the rotation of the rotating plate 8, the L-shaped frame 7 slides along the first sliding plate 6, and finally the rotating plate 8 moves to a position corresponding to the flat area between the crest of the corrugated plate and the adjacent trough, and is parallel to this flat area, while the first fixed shell 9 is perpendicular to this flat area.

[0065] After the telescopic end of the first electric push rod 14 stops extending, the staff starts the second electric push rod 19, the telescopic end of the second electric push rod 19 extends and drives the connecting rod 20 to move, and the connecting rod 20 drives the two third sliding plates 21 to move synchronously. In the process of the movement of the third sliding plate 21 (hereinafter, the description of the first extrusion block 22 and the second extrusion block 23 is based on the adjacent set of L-shaped frames 7 and related parts and Fig.10 For example, the third sliding plate 21 drives the first extrusion block 22 and the second extrusion block 23 thereon to move leftward. After the second extrusion block 23 contacts the second sliding member 17 on the left side, the second extrusion block 23 squeezes the second sliding member 17, so that the second sliding member 17 moves into the second fixed shell 16 and compresses the first elastic member until the upper bottom surface of the second extrusion block 23 and the second sliding member 17 are in an extruded state and then the second electric push rod 19 is closed.

[0066] During the movement of the second sliding member 17 into the second fixed shell 16, the second sliding member 17 pushes the hydraulic oil in the second fixed shell 16 into the first fixed shell 9 through the first oil guide pipe. The hydraulic oil entering the first fixed shell 9 pushes the transfer plate 18 to move. The movement of the transfer plate 18 drives the first sliding member 10 to move through the second elastic member. During the movement of the first sliding member 10, the side away from the transfer plate 18 contacts the corrugated plate and is blocked by the corrugated plate. After the first sliding member 10 is blocked by the corrugated plate, the transfer plate 18 continues to move and compresses the second elastic member. After compression, the second elastic member applies a thrust to the first sliding member 10. Finally, the corrugated plate is clamped and fixed by the corresponding first sliding members 10 on the two first sliding plates 6. By adjusting the angle of the rotating plate 8 and the first fixed shell 9 thereon, when the corrugated plate is fixed, the first sliding member 10 clamps the relatively flat area of ​​the tinplate to reduce damage to the corrugated plate.

[0067] After the corrugated plate is clamped, the staff starts the displacement module 3, and drives the support plate 5 to move downward through the displacement module 3, so that the bottom of the corrugated plate is placed in the passivation liquid in the liquid storage box 1. During the downward movement of the support plate 5, the second sliding plate 11 slides along the limit groove of the connecting member 15 and gradually breaks away from the limit, and the sliding column 12 gradually breaks away from contact with the corrugated plate. After the corrugated plate is completely placed in the passivation liquid, the displacement module 3 is closed to allow the corrugated plate to react in the passivation liquid. At this time, the liquid level of the passivation liquid is located between the second fixed shell 16 and the third sliding plate 21. , when the corrugated plate reacts in the passivation liquid for a period of time, the staff starts the second electric push rod 19 to retract its telescopic end. The retraction of the telescopic end of the second electric push rod 19 drives the third sliding plate 21 to move to the right through the connecting rod 20. Due to the pressure exerted by the first elastic member on the second extrusion block 23 through the second sliding member 17, the third sliding plate 21 only drives the first extrusion block 22 to move to the right while moving. The second extrusion block 23 slides relatively along the slide groove on the third sliding plate 21, and the first extrusion block 22 moves to stretch the elastic telescopic rod 24.

[0068] During the movement of the first extrusion block 22 to the right, after the first extrusion block 22 moves to contact the second sliding member 17 on the right, the first extrusion block 22 squeezes the second sliding member 17 to make it slide into the second fixed shell 16, and finally pushes out the first sliding member 10 in the first fixed shell 9 connected to the second fixed shell 16 on the right and clamps the corrugated plate (the action here is consistent with the action of the second extrusion block 23 squeezing the second sliding member 17 on the left to finally move the first sliding member 10 out), until the upper bottom surface of the first extrusion block 22 and the second sliding member 17 are in an extruded state, at this time the elastic telescopic rod 24 is stretched to the limit state, and then the first extrusion block 22 continues to move so that its upper bottom surface slides relative to the second sliding member 17 on the right, at this time the first extrusion block 22 moves while pulling the second extrusion block 23 to move through the elastic telescopic rod 24, until the upper bottom surface of the second extrusion block 23 is out of contact with the second sliding member 17 on the left and the second electric push rod 19 is closed, at this time the second sliding member 17 on the right is still in an extruded state with the upper bottom surface of the first extrusion block 22.

[0069] After the upper bottom surface of the second extrusion block 23 is out of contact with the second sliding member 17 on the left and the second electric push rod 19 is closed, the pressure of the second sliding member 17 on the second extrusion block 23 disappears, and the second extrusion block 23 gradually moves to the right under the action of the elastic telescopic rod 24 until the telescopic end of the elastic telescopic rod 24 is completely retracted and drives the second extrusion block 23 to fit with the first extrusion block 22 and then stops. In the process of the elastic telescopic rod 24 driving the second extrusion block 23 to return to its original position, the left second sliding member 17 is gradually returned to its original position under the action of the first elastic member. In the process of the second sliding member 17 returning to its original position, the second sliding member 17 enters the The hydraulic oil in the first fixed shell 9 flows back to the second fixed shell 16 through the first oil pipe. The hydraulic oil in the first fixed shell 9 flows back, and the elastic force of the second elastic member between the first sliding member 10 and the transfer plate 18 is released. After the elastic force of the second elastic member is released, the transfer plate 18 is gradually reset under the action of the returning hydraulic oil. The reset of the transfer plate 18 drives the first sliding member 10 to reset synchronously through the second elastic member. At this time, the clamping position of the corrugated plate is changed, so that the initial clamping position of the corrugated plate contacts the passivation liquid, so that the passivation liquid can completely cover the corrugated plate, thereby improving the passivation integrity of the corrugated plate.

[0070] After the corrugated plate reacts in the passivation solution for a specified time, the staff starts the displacement module 3, and drives the support plate 5 to move upward through the displacement module 3, so as to take the corrugated plate out of the passivation solution. In the process of the support plate 5 moving upward, the second sliding plate 11 and the limiting groove of the connecting member 15 are limited again. When the fixed plate 13 and the sliding column 12 are on the same horizontal plane, the displacement module 3 is temporarily stopped and the second electric push rod 19 is started, so that the telescopic end of the second electric push rod 19 extends out and drives the third sliding plate 21 to move through the connecting rod 20, so that the first extrusion block 22 moves leftward, and the first extrusion block 22 moves leftward to be connected with the right second extrusion block 21. The second sliding member 17 gradually leaves the extrusion state until the first extrusion block 22 and the second extrusion block 23 move to the initial position and then close the second electric push rod 19. After the first extrusion block 22 releases the extrusion of the second sliding member 17 on the right side, the second sliding member 17 is gradually reset under the action of the first elastic member, and finally the first sliding member 10 in the first fixed shell 9 connected to the right second fixed shell 16 is reset (the action here is consistent with the action when the second sliding member 17 on the left side is reset above). After the first sliding member 10 is reset, its clamping of the corrugated plate is released, and the staff transfers the corrugated plate through the external transfer device arranged in advance.

[0071] After all the corrugated plates are removed and transferred, the staff starts the first electric push rod 14 to retract its telescopic end. The retraction of the telescopic end of the first electric push rod 14 drives the second sliding plate 11 and the first sliding plate 6 to move to both sides until the sliding column 12 contacts the fixed plate 13 and is squeezed and reset by the fixed plate 13 and then stops. In the process of the sliding column 12 being squeezed and reset, the first sliding plate 6 drives the L-shaped frame 7 thereon to move in the direction close to the U-shaped rod 1301. After the L-shaped frame 7 contacts the limit block 1302 on the U-shaped rod 1301, the limit block 1302 squeezes the L-shaped frame 7 to slide and reset. After the L-shaped frame 7 is reset, the first sliding plate 6 continues to move to make the rotating plate 8 contact with the U-shaped rod 1301, and squeezes the rotating plate 8 through the U-shaped rod 1301 to reset the rotating plate 8.

[0072] After the rotating plate 8 and the sliding column 12 are reset, the staff controls the first electric push rod 14 to extend its telescopic end, and the extension of the telescopic end of the first electric push rod 14 drives the second sliding plate 11 and the first sliding plate 6 to move to the initial position. Then the staff closes the first electric push rod 14 and starts the displacement module 3. The displacement module 3 controls the support plate 5 to move upward until the sliding column 12 and the rotating plate 8 are on the same horizontal plane, and then the displacement module 3 is closed. Then the above operation can be repeated to passivate the corrugated plate again.

[0073] Example 2: Based on Example 1, please refer to Figure 6 , Figure 7 and Fig. 9 , and further includes: hydraulic cylinders 25, the number of which is the same as the number of the second fixed shells 16, which are respectively fixed to the adjacent first sliding plates 6, and a second oil pipeline is connected between the hydraulic cylinders 25 and the adjacent first fixed shells 9.

[0074] In the above solution, the hydraulic cylinder 25 is of an existing structure, the hydraulic rod in the hydraulic cylinder 25 is initially in an extended state, and the hydraulic cylinder 25 and the second oil pipeline are both filled with hydraulic oil.

[0075] See also Fig.10 , Fig.12 and Fig.13 , and also includes: fixed frames 26, the number of which is the same as the number of hydraulic cylinders 25, the fixed frames 26 are divided into a group of two, and the two fixed frames 26 in the same group are respectively fixed to the adjacent first extrusion block 22 and the second extrusion block 23, the fixed frames 26 are slidably connected with the extrusion plate 27, and a third elastic member is fixed between the two, the elastic coefficient of the third elastic member between the fixed frame 26 and the extrusion plate 27 is greater than the elastic coefficient of the second elastic member between the first sliding member 10 and the transfer plate 18, the extrusion plate 27 is extruded and matched with the telescopic end of the hydraulic rod in the adjacent hydraulic cylinder 25, and the two are magnetically matched.

[0076] In the above scheme, the third elastic member between the fixed frame 26 and the extrusion plate 27 is set as a spring, which is used to drive the extrusion plate 27 to reset. The elastic coefficient of the third elastic member between the fixed frame 26 and the extrusion plate 27 is greater than the elastic coefficient of the second elastic member between the first sliding member 10 and the transmission plate 18, so that the extrusion plate 27 pushes the transmission plate 18 to compress the second elastic member to the limit through the hydraulic oil in the hydraulic cylinder 25 each time before compressing the third elastic member, ensuring that the second elastic member is compressed to the same state each time. The extrusion plate 27 is magnetically matched with the telescopic end of the hydraulic rod in the adjacent hydraulic cylinder 25, so that the extrusion plate 27 can drive the hydraulic rod in the hydraulic cylinder 25 to reset.

[0077] When fixing the corrugated plate, the second extrusion block 23 squeezes the second sliding member 17 so that the first sliding member 10 clamps the corrugated plate. After the upper bottom surface of the second extrusion block 23 and the second sliding member 17 are in a mutually squeezed state, the second extrusion block 23 continues to move so that the extrusion plate 27 squeezes the telescopic end of the hydraulic rod in the hydraulic cylinder 25, so that the hydraulic rod of the hydraulic cylinder 25 slides inward, and the hydraulic oil in the hydraulic cylinder 25 is pushed into the first fixed shell 9 through the second oil guide pipe. The hydraulic oil entering the first fixed shell 9 squeezes the transmission plate 18, so that the transmission plate 18 and the first The second elastic member between the sliding members 10 is compressed to the limit state, and then the second extrusion block 23 continues to move. At this time, the hydraulic oil in the hydraulic cylinder 25 cannot enter the first fixed shell 9, so that the extrusion plate 27 slides along the fixed frame 26 and squeezes the third elastic member between the two, until the right side of the upper bottom surface of the second extrusion block 23 is in the corresponding position with the second sliding member 17, and stops. The hydraulic oil in the hydraulic cylinder 25 supplements the hydraulic oil in the first fixed shell 9, so that the clamping force of the first sliding member 10 on the corrugated plate is maintained at the same force, thereby improving the stability of the clamping of the corrugated plate.

[0078] During the process of resetting after the second extrusion block 23 is out of contact with the second sliding member 17, the elastic force of the third elastic member between the extrusion plate 27 and the fixed frame 26 is released, and the extrusion plate 27 releases the extrusion of the hydraulic rod in the hydraulic cylinder 25 and moves away from the hydraulic cylinder 25. The extrusion plate 27 drives the hydraulic rod of the hydraulic cylinder 25 to move and reset through magnetic force. The reset of the hydraulic rod of the hydraulic cylinder 25 draws the hydraulic oil in the first fixed shell 9 back into the hydraulic cylinder 25, so that the transfer plate 18 moves and resets and drives the first sliding member 10 to reset through the second elastic member.

[0080] S1: Place the corrugated plate between the two second sliding plates 11, and the first electric push rod 14 drives the sliding column 12 and the first fixed shell 9, so that the first fixed shell 9 changes its angle to be perpendicular to the corrugated plate;

[0081] S2: The second electric push rod 19 drives the second extrusion block 23, and the second extrusion block 23 controls the first sliding member 10 to fix the corrugated plate;

[0082] S3: After the corrugated plate is fixed, the second extrusion block 23 drives the hydraulic cylinder 25, and the transmission plate 18 compresses the second elastic member;

[0083] S4: After the corrugated plate is fixed, the displacement module 3 drives the support plate 5 to immerse the corrugated plate in the passivation liquid;

[0084] S5: When the corrugated plate reacts with the passivation liquid, the second electric push rod 19 drives the first extrusion block 22, and the first extrusion block 22 controls the second extrusion block 23 and the first sliding member 10 to change the fixed position of the corrugated plate;

[0085] S6: After the reaction between the corrugated plate and the passivation liquid is finished, the displacement module 3 drives the support plate 5 to move the corrugated plate out of the passivation liquid;

[0086] S7: After the corrugated plate is removed from the passivation liquid, the second electric push rod 19 drives the first extrusion block 22 to release the corrugated plate and remove it, and the first sliding member 10 is reset;

[0087] S8: After the corrugated plate is removed, the first electric push rod 14 drives the sliding column 12 and the first fixed shell 9, and the sliding column 12 and the first fixed shell 9 are reset;
