Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metal sheet technology, specifically relating to a surface treatment device for ultra-long plates. Background Technology
[0002] Surface treatment is a crucial process in the sheet metal processing industry, especially for finished sheets. In actual production, zirconium alloy sheets undergo final surface treatment—degreasing and pickling—after polishing to achieve the desired product delivery condition. The process typically involves placing sheets one by one into a pickling frame and slowly immersing them in the pickling solution. A crane moves back and forth to ensure uniform corrosion. However, for sheets that are long (2000mm≤L≤3000mm), narrow (50≤W≤200mm), and thin (δ≤3mm), their own weight often causes concavity and flatness deformation in the middle, posing a risk of them falling into the acid bath. This can render the sheets unusable and result in significant economic losses. Therefore, developing a novel surface treatment device for ultra-long sheets, with a design that supports the middle of the sheet and prevents it from falling into the pickling solution, is a necessary solution. Utility Model Content
[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide a surface treatment device for extra-long plates. After placing the extra-long plate in the device, it is placed in an acid pickling tank for surface treatment. The treatment process is safe and reliable, and the surface quality of the extra-long plate after surface treatment is pentagonal and meets the requirements.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] This invention proposes a surface treatment device for ultra-long plates, including an acid pickling frame with an open top. A first rotating rod and a second rotating rod are arranged parallel to each other on the upper end of the acid pickling frame. A first swing arm is arranged at intervals along the axial direction on the first rotating rod, and a second swing arm is arranged at intervals along the axial direction on the second rotating rod. The first swing arm and the second swing arm are staggered and are both located between the first rotating rod and the second rotating rod.
[0006] Specifically, both the first rotating rod and the second rotating rod are arranged along the length of the pickling frame and are at the same height.
[0007] Specifically, the pickling frame is also provided with a third rotating rod and a fourth rotating rod. The inner side of the third rotating rod is provided with a third swing arm at intervals along its axial direction, and the inner side of the fourth rotating rod is provided with a fourth swing arm at intervals along its axial direction. The third rotating rod is located below the first rotating rod, and the fourth rotating rod is located below the second rotating rod. The third swing arm is staggered from the first swing arm, and the fourth swing arm is staggered from the second swing arm.
[0008] Specifically, the lengths of the third and fourth swing arms are both less than the lengths of the first and second swing arms.
[0009] Specifically, the lengths of the third and fourth swing arms are both 1 / 4 to 1 / 3 of the distance between the third and fourth rotating rods.
[0010] Specifically, one end of the first rotating rod, one end of the second rotating rod, one end of the third rotating rod, and one end of the fourth rotating rod are respectively connected to the output shafts of the first servo motor, the second servo motor, the third servo motor, and the fourth servo motor located outside the pickling frame.
[0011] Specifically, one end of the first rotating rod is connected to the output shaft of the first servo motor located outside the pickling frame. The output shaft of the first servo motor is also connected to the end of the second rotating rod via a belt. One end of the fourth rotating rod is connected to the output shaft of the fourth servo motor located outside the pickling frame. The output shaft of the fourth servo motor is also connected to the third rotating rod via a belt.
[0012] Specifically, the pickling frame has a length of L and a width of W, where 2100mm≤L≤3500mm; 100mm≤W≤1000mm.
[0013] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:
[0014] (1) This utility model rotates the first rotating rod and the second rotating rod to make the first swing arm and the second swing arm cross into a "V" shape, and places the plate horizontally between the first swing arm and the second swing arm, so that the plate is connected to the first swing arm and the second swing arm at points, which increases the contact area between the plate and the pickling solution, avoids color difference and local unevenness on the surface of the plate during pickling, and ensures the stability of the surface quality of the plate after pickling. At the same time, multiple first swing arms and second swing arms cross to support the plate, effectively lifting the middle of the extra-long plate, so that the plate is not deformed and the flatness is reduced during the pickling operation, and ensures the safety, reliability and quality stability of the plate during the pickling process.
[0015] (2) The present invention also provides a third swing arm and a fourth swing arm, so that the plate can also be surface treated in a vertical operation mode. When the plate is upright in the processing device, the first swing arm and the second swing arm form a "V" shape to support the bottom of the plate, and the upper part of the plate rests on the third swing arm or the fourth swing arm. The present invention can perform surface treatment on the plate in both horizontal and vertical operation modes, which shows that the device has strong practicality and flexibility, making the application range and application environment of the device relatively wide.
[0016] (3) This utility model has a simple structure, is easy to operate, and has low manufacturing cost. Attached Figure Description

[0025] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses consistent with some aspects of this invention as detailed in the appended claims.
[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Example
[0027] refer to Figure 1 This embodiment proposes a surface treatment device for ultra-long plates, including an acid pickling frame 7 with an open top. A first rotating rod 1 and a second rotating rod 8 are arranged parallel to each other on the upper end of the acid pickling frame 7. A first swing arm 2 is arranged at intervals along the axial direction of the first rotating rod 1, and a second swing arm 9 is arranged at intervals along the axial direction of the second rotating rod 8. The first swing arm 2 and the second swing arm 9 are staggered and are both located between the first rotating rod 1 and the second rotating rod 8. Preferably, the first rotating rod 1 and the second rotating rod 8 are arranged along the length direction of the acid pickling frame 7 and are at the same height.
[0028] refer to Figure 2 and Figure 3 In this embodiment, when surface treating the plate 11, an appropriate amount of pickling solution is injected into the pickling frame 7. The first rotating rod 1 and the second rotating rod 8 are rotated so that the first swing arm 2 and the second swing arm 9 cross in a "V" shape within the pickling frame 7. The plate 11 is then placed horizontally between the first swing arm 2 and the second swing arm 9. At this time, the two long sides of the plate 11 form point contact with the first swing arm 2 and the second swing arm 9, so that the surface of the plate 11 can be uniformly treated. At the same time, the first swing arm 2 and the second swing arm 9 cross in a "V" shape to effectively support the middle of the extra-long plate 11, so that the plate 11 is not deformed or its flatness is reduced during the pickling process, thus effectively ensuring the surface quality of the plate 11.
[0029] To enable both horizontal and vertical operation of the plate 11, this embodiment also includes a third rotating rod 3 and a fourth rotating rod on the pickling frame 7. The third rotating rod 3 has a third swing arm 4 spaced axially along its inner side, and the fourth rotating rod has a fourth swing arm 10 spaced axially along its inner side. The third rotating rod 3 is located below the first rotating rod 1, and the fourth rotating rod is located below the second rotating rod 8. The third swing arm 4 is offset from the first swing arm 2, and the fourth swing arm 10 is offset from the second swing arm 9. When surface treating the plate 11, if the plate 11 is being surface treated horizontally, rotating the first rotating rod 1 and the second rotating rod 8 causes the first swing arm 2 and the second swing arm 9 to cross in a "V" shape within the pickling frame 7. Rotating the third rotating rod 3 and the fourth rotating rod causes the third swing arm 4 and the fourth swing arm 10 to both point vertically downwards, without affecting the horizontal placement of the plate 11. If the plate 11 is being surface treated vertically... When performing surface treatment in a vertical position, rotate the first rotating rod 1 and the second rotating rod 8 so that the first swing arm 2 and the second swing arm 9 cross in a "V" shape within the pickling frame 7. Rotate the third rotating rod 3 or the fourth rotating rod so that the third swing arm 4 passes through the space between the first swing arms 2 or the fourth swing arm 10 passes through the space between the second swing arms 9 to support the upper part of the plate 11. After the plate 11 is placed vertically into the pickling frame 7, the bottom end of the plate 11 is supported by the intersection of the first swing arm 2 and the second swing arm 9, and the upper part of the plate 11 is supported by the free ends of the third swing arm 4 and the fourth swing arm 10. In this way, the upper part of the plate 11 also rests against the third swing arm 4 or the fourth swing arm 10 in a point contact manner. In this embodiment, when the plate is in a vertical state, the third swing arm 4 or the fourth swing arm 10 preferably forms a 0° angle with the horizontal direction, and the lengths of the third swing arm 4 and the fourth swing arm 10 are both 2 / 7 of the distance between the third rotating rod 3 and the fourth rotating rod.
[0030] To enable the first swing arm 2, the second swing arm 9, the third swing arm 4, and the fourth swing arm 10 to rotate freely at different angles, one end of the first rotating rod 1, one end of the second rotating rod 8, one end of the third rotating rod 3, and one end of the fourth rotating rod can be connected to the output shafts of the first servo motor 5, the second servo motor, the third servo motor, and the fourth servo motor 6 located outside the pickling frame 7, respectively. That is, each rotating rod is controlled by a servo motor individually. Alternatively, one end of the first rotating rod 1 and one end of the fourth rotating rod can be connected to the output shafts of the first servo motor 5 and the fourth servo motor 6 located outside the pickling frame 7, respectively. The output shaft of the first servo motor 5 is also connected to the end of the second rotating rod 8 via a belt, and the output shaft of the fourth servo motor 6 is also connected to the end of the third rotating rod 3 via a belt.
[0031] In the above embodiments, the lengths of the first swing arm 2, the second swing arm 9, the third swing arm 4, and the fourth swing arm 10, as well as their included angles with the horizontal direction, can be determined according to design requirements, so as to place the plate 11 as required.
[0032] Because the extra-long plate 11 is relatively long (2000mm≤L≤3000mm), narrow in width (50≤W≤200mm), and thin in thickness (δ≤3mm), the specifications of the pickling frame 7, the distance between the first rotating rod 1 and the second rotating rod 8, the distance between the second rotating rod 8 and the third rotating rod 3, the length of the first rotating arm, the length of the second rotating arm, the length of the third rotating arm, the length of the fourth rotating arm, and the installation position of the servo motor can all be determined according to the specifications of the plate 11 or design requirements. While ensuring the safety of the pickling liquid level, the plate 11 should be able to be submerged in the pickling liquid after being placed in the pickling frame 7. Preferably, the lengths of the third swing arm 4 and the fourth swing arm 10 are both 1 / 4 to 1 / 3 of the distance between the third rotating rod 3 and the fourth rotating rod. The length L of the pickling frame 7 is set to 2100mm≤L≤3500mm, and the width W of the pickling frame 7 is set to 100mm≤W≤1000mm.
[0033] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this utility model.
[0034] It should be understood that this utility model is not limited to the content already described above, and various modifications and changes can be made without departing from its scope. The scope of this utility model is limited only by the appended claims.
