Description

Technical Field

[0001] The invention relates to the field of tools in the production process of aluminum materials, and in particular to an aluminum profile oxidation clamping device used in the loading and unloading process links of aluminum material oxidation. Background Art

[0002] In the process of aluminum production and processing, it is necessary to carry out oxidation treatment on the aluminum in production to achieve the ideal surface quality requirements. On the beam in the production workshop, a certain number of profiles are mainly hung by the clamp, and then the beam is placed in the oxidation tank surface by the manipulator, in which the end of the profile clamp is exposed 2-3 cm outside the tank liquid, and the rest is completely immersed in the oxidation liquid surface, and the profile surface with a certain film thickness and a certain color is obtained through the anodic oxidation reaction. In the process of loading and unloading, the reliability of the clamp quality and the rationality of the structure will be directly related to the production rhythm of loading and unloading. There are two kinds of traditional clamps: one is offline manual clamping, which is more common in horizontal oxidation lines. Its disadvantages are: the profile needs to be framed offline, and then a special person is responsible for transporting it to each clamping station; the horizontal clamping method has a slow manual clamping speed, and the staffing is 2-3 times that of the vertical oxidation line under the same output; on the other hand, horizontal oxidation is limited by the influence of the deflection of the profile on its length direction. The limited length of the profile will further affect the yield and output. In general, this offline horizontal clamping method requires more personnel to operate and has relatively lower economic benefits than vertical clamping. Another method is the online clamp of the vertical oxidation line. Compared with the horizontal offline clamping method, the vertical clamp has made a great breakthrough, but the clamps on the market have problems such as sticking, copper clamps wear quickly, poor acid and alkali resistance and fast corrosion, and failure to match the beam deflection, resulting in waste of profile length. Summary of the invention

[0003] In view of the above problems, the purpose of the present invention is to provide an aluminum profile oxidation clamping device which solves the disadvantages of the original oxidation clamps sticking to materials, copper plates not being wear-resistant, and having a relatively short service life, and improves the stability of automated production, reduces the frequency of clamp replacement, and reduces costs and increases efficiency.

[0004] To achieve the above-mentioned purpose, the present invention provides an aluminum profile oxidation clamping device, comprising a beam and a plurality of clamping mechanisms arranged on the beam, characterized in that the clamping mechanism comprises two side-by-side conductive large copper plates, a connecting small plate fixed by bolts between the two conductive large copper plates, a connecting rod structure respectively arranged on the two side-by-side conductive large copper plates on one side of the connecting small plate, and a spring arranged between the connecting rod structure and the connecting small plate. The connecting rod structure comprises a clamping small copper plate partially extending outside the end of the conductive large copper plate respectively arranged below the end of the conductive large copper plate, a first side plate and a second side plate respectively arranged on both sides of the conductive large copper plate above the corresponding clamping small copper plate, a first positioning shaft and a second positioning shaft arranged between the first side plate and the second side plate, a connecting straight piece arranged on the first positioning shaft, a bending piece arranged on the second positioning shaft to cooperate with the clamping small copper plate to clamp the material, and a crank arm arranged between the end of the connecting straight piece and the end of the bending piece.

[0005] One end of the spring is connected to the crank arm rod, and the other end is connected to the bolt on the connecting small plate.

[0006] In some embodiments, the bending member is an S-shaped bending member.

[0007] In some embodiments, the middle of the S-shaped bending piece is connected to the second positioning shaft. One end of the S-shaped bending piece is movably connected to the end of the crank arm, and the other end is provided with anti-slip teeth on the end surface contacting the small copper plate for clamping materials.

[0008] In some embodiments, the crank arm is an S-shaped crank arm.

[0009] In some embodiments, the bending position on the S-shaped crank arm is movably connected to the connecting straight piece.

[0010] In some embodiments, two side-by-side large conductive copper plates are respectively provided with a plurality of corresponding mounting holes, so that the mounting holes can adapt to the deflection design of the beam, realize compensation for the height change caused by the deflection, and thus improve the yield to a certain extent.

[0011] In some embodiments, a conductive ceramic coating is provided on the surface of the small copper plate for sandwiching materials, which can increase the wear resistance of the surface of the small copper plate for sandwiching materials.

[0012] The beneficial effect of the present invention is to solve the drawbacks of the original oxidation clamps sticking to materials, copper plates not being wear-resistant, and having a relatively short service life, and to improve the stability of automated production, reduce the frequency of replacing clamps, and reduce costs and increase efficiency. After the improvement, the bending part and the small copper plate for clamping materials are opened and closed in coordination with each other through the motion trajectory of the connecting rod structure, so as to realize the functions of clamping and loosening the profiles, and solve the drawbacks of the original oxidation clamps sticking to materials. At the same time, the height between the bending part and the small copper plate for clamping materials can be adjusted by utilizing the motion trajectory of the connecting rod structure to adapt to the working conditions of the actual production of clamping materials, so that not only the original oxidation clamps sticking to materials are avoided, but also the use is more flexible. In addition, a conductive ceramic coating is added to the surface of the small copper plate for clamping materials. The electro-ceramic coating can increase the wear resistance between the small copper plate for clamping materials and the bending part, so as to increase the wear resistance and improve the service life of the overall structure. In addition, two rows of closely spaced holes are designed on the top of the large conductive copper plate to meet the height requirements of the clips at different positions relative to the beam. This is because the beam is a rigid structure supported at both ends. Under the dual effects of its own weight and the weight of the profile, the beam will have a more obvious deflection. Therefore, the profile close to the middle can compensate for the influence of the beam deflection on the profile according to the hole position, thereby compensating for the height change caused by the deflection, thereby improving the yield rate to a certain extent.

[0019] The invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1-6As shown, an oxidation clamping device for aluminum profiles includes a main beam 01 and a plurality of clamping mechanisms 02 arranged on the main beam 01, wherein the clamping mechanism 02 includes two side-by-side conductive large copper plates 21, a connecting small plate 23 connected and fixed by bolts 22 between the two conductive large copper plates 21, connecting rod structures 24 respectively arranged on the two side-by-side conductive large copper plates 21 on one side of the connecting small plate 23, and a spring 25 arranged between the connecting rod structure 24 and the connecting small plate 23. Through the motion trajectory of the connecting rod structure 24, the bending part and the clamping small copper plate are opened and closed in coordination with each other, so as to realize the function of clamping and loosening the profile, and solve the drawback of the original oxidation clamp sticking material. At the same time, the motion trajectory of the connecting rod structure 24 can be used to adjust the height between the bending part and the clamping small copper plate to adapt to the working conditions of clamping materials in actual production.

[0021] The connecting rod structure 24 includes a small copper plate 241 for clamping materials, which is partially extended to the outside of the end of the conductive large copper plate 21, respectively provided below the end of the conductive large copper plate 21, a first side plate 242 and a second side plate 243 respectively provided on both sides of the conductive large copper plate 21 above the corresponding small copper plate 241 for clamping materials, a first positioning shaft 244 and a second positioning shaft 245 provided between the first side plate 242 and the second side plate 243, a connecting straight piece 246 provided on the first positioning shaft 244, a bending piece 247 provided on the second positioning shaft 245 for clamping materials in cooperation with the small copper plate 241 for clamping materials, and a crank arm 248 provided between the end of the connecting straight piece 246 and the end of the bending piece 247.

[0022] One end of the spring 25 is connected to the crank arm 248, and the other end is connected to the bolt 22 on the connecting small plate 23. The bending piece 247 is an S-shaped bending piece. The middle position of the S-shaped bending piece 247 is connected to the second positioning shaft 245. One end of the S-shaped bending piece 247 is movably connected to the end of the crank arm 248, and the other end is provided with anti-slip teeth on the end surface that contacts the small copper plate 241 for clamping materials. The crank arm 248 is an S-shaped crank arm. The bending position on the S-shaped crank arm is movably connected to the connecting straight piece 246. A plurality of mounting holes 26 corresponding to each other are respectively and sequentially provided on the two side-by-side large conductive copper plates 21. The top of the conductive large copper plate 21 is designed with two rows of closely spaced holes to meet the height requirements of the clip relative to the beam 01 at different positions. The reason is that the beam 01 is a rigid structure supported at both ends. Under the dual effects of its own weight and the weight of the profile, the beam 01 will have a more obvious deflection. Therefore, the profile close to the middle can compensate for the influence of the deflection of the beam 01 on the profile according to the hole position. The traditional method is to make the profile longer, which will cause waste of the extruded finished product. This method can avoid this problem and has positive significance for improving the yield rate. Therefore, the top of the conductive large copper plate 21 is designed with two rows of closely spaced mounting holes 26 to meet the height requirements of the connecting rod structure 24 at different positions relative to the beam 01, so as to compensate for the height change caused by the deflection. The surface of the small copper plate 241 for clamping materials is provided with a conductive ceramic coating. The electroceramic coating can increase the wear resistance between the small copper plate 241 for clamping materials and the bending part 247. A layer of nano material is sprayed on the non-working surface to improve the acid and alkali resistance, thereby increasing the service life of the bending part 247 and the small copper plate 241 for clamping materials.

[0023] Working principle: The initial clamping force allows the profile to be firmly fixed between the bending part 247 of the connecting rod structure 24 and the small copper plate 241 for clamping materials. The external driving power acts on the crank arm 248 to further stretch the spring 25. However, after the profile is loosened, the bending part 247 and the small copper plate 241 for clamping materials can be automatically reset under the action of the contraction force of the spring 25.

[0024] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the invention.
