Description

Technical Field

[0001] This invention relates to the field of aluminum rod technology, specifically to a high-strength corrosion-resistant aluminum rod and its preparation method. Background Technology

[0002] Aluminum rods are a type of aluminum product. The casting of aluminum rods includes melting, purification, impurity removal, degassing, slag removal, and casting processes. After aluminum rod production, the aluminum rod workpieces need to be stacked and transferred.

[0003] In existing technology, aluminum rods are directly stacked and bound with ropes for positioning. This results in collisions and wear between adjacent aluminum rods, and the exposed worn parts are prone to corrosion. If a wooden pad structure is added between two adjacent aluminum rods, it will inevitably increase the storage volume of the bound aluminum rods, thus increasing transportation costs.

[0004] Therefore, we need a high-strength, corrosion-resistant aluminum rod and its preparation method to solve the problem of collision and wear when existing aluminum rods are stacked. This method can ensure that the aluminum rods are neatly arranged while avoiding collision and wear between adjacent aluminum rods. Summary of the Invention

[0005] The purpose of this invention is to provide a high-strength corrosion-resistant aluminum rod and its preparation method, so as to solve the problem of collision and wear when stacking existing aluminum rods as mentioned in the background art. This invention can ensure that the aluminum rods are neatly arranged while avoiding collision and wear between adjacent aluminum rods.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-strength corrosion-resistant aluminum rod, comprising an aluminum rod body, the surface of which is coated with a high-strength anti-corrosion coating, protective sleeves fitted at both ends of the aluminum rod body, a reserved groove on the surface of the protective sleeve, multiple clamping handles movably inserted into the surface of the reserved groove, a rotating ring fitted inside the reserved groove, the rotating ring pressing the clamping handles to clamp the aluminum rod body, multiple notches on the surface of the rotating ring, when the rotating ring is rotated so that the notches and clamping handles are opposite each other, the clamping handles no longer clamp the aluminum rod body, and multiple mounting planes on the outer ring surface of the protective sleeve.

[0007] Preferably, the protective sleeve has a circular ring plate structure, and a sealing plate is fixed at one end of the protective sleeve. The diameter of the sealing plate is smaller than the outer diameter of the protective sleeve. There are four mounting planes, which are arranged in a cross shape.

[0008] Preferably, the reserved groove is an annular groove, and the surface of the reserved groove is provided with multiple insertion ports, each corresponding to a clamping handle. The clamping handle is movably inserted into the insertion port, and the end of the clamping handle facing the reserved groove is provided with two bevels, which are distributed in a figure-eight shape.

[0009] Preferably, the other end of the clamping handle is an arc-shaped curved surface with a notch. A rubber traction belt is fixed at the center of the notch. The two ends of the rubber traction belt are fixed to two parallel sidewalls of the insertion port, and a rubber pad is fixed on the arc-shaped curved surface. When the rotating ring squeezes the clamping handle to clamp the aluminum rod body, the rubber traction belt is in a state of tension deformation.

[0010] Preferably, a retaining ring is fixedly fitted inside the reserved groove, and a rubber ring is fixed on the side of the retaining ring facing the rotating ring. The rubber ring is clamped between the rotating ring and the retaining ring to produce elastic deformation.

[0011] Preferably, the outer ring surface of the rotating ring is provided with finger grooves, and there are multiple finger grooves, which are arranged at equal distances and of equal size along the outer ring surface of the rotating ring.

[0012] Preferably, the mounting surface at the top of the protective sleeve is fixed with an assembly block, and the mounting surface at the bottom of the protective sleeve is provided with an assembly groove. The assembly groove and the assembly block are matched. When the two sets of aluminum rod bodies are stacked, the assembly block at the top of one set of protective sleeves is inserted into the assembly groove at the bottom of the other set of protective sleeves.

[0013] Preferably, a slot is provided on the mounting surface of one side of the protective sleeve. The slot is an arc-shaped groove. An guide strip is fixed on the mounting surface of the other side of the protective sleeve. A rubber clip is fitted on the end of the guide strip away from the mounting surface. The rubber clip is an arc-shaped strip. The rubber clip matches the slot. When the two sets of aluminum rod bodies are assembled side by side, the rubber clip on the surface of one set of protective sleeves is inserted into the slot on the surface of the other set of protective sleeves.

[0014] Preferably, the high-strength anti-corrosion coating raw materials, by weight, comprise: 58-59 parts modified epoxy resin, 11-12 parts polyurethane resin, 16-17 parts cellulose acetate, 53-54 parts organic solvent, 1.6-1.7 parts pigment, 0.6-0.7 parts defoamer, 0.9-1.1 parts leveling agent, 0.08-0.09 parts mildew inhibitor, 4.4-4.6 parts modified attapulgite, 2.6-2.8 parts calcined kaolin, 2.6-2.7 parts talc, and aluminum-zirconium coupling agent TL-2.

[0015] 0.6-0.7 parts, hydrogenated castor oil 0.63-0.67 parts, ferric chloride 0.24-0.33 parts, cobalt octate 0.08-0.09 parts.

[0016] A method for preparing a high-strength corrosion-resistant aluminum rod includes the following steps:

[0017] S1: Weigh the raw materials according to the mass percentage of each component in the high-strength corrosion-resistant aluminum rod;

[0018] S2: Melt the raw materials by heating to obtain molten aluminum;

[0019] S3: When the temperature of the molten aluminum reaches 750℃-770℃, the molten aluminum is refined to obtain refined molten aluminum.

[0021] S5: Cool the refined aluminum liquid to 690℃-710℃, refine it using AlTi5C0.18 wire, degas it, filter it to remove impurities, and obtain the refined aluminum liquid.

[0022] S6: The refined aluminum liquid is placed in a mold and cast under the conditions of casting temperature of 670℃-690℃, casting speed of 250mm / min-550mm / min, and cooling water quenching of 100ton / h-120ton / h to obtain a casting rod.

[0023] S7: The cast rod is subjected to T6 heat treatment to obtain a high-strength corrosion-resistant aluminum rod with a size of Φ35mm-90mm.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] The high-strength corrosion-resistant aluminum rod and its preparation method proposed in this invention, by covering both ends of the aluminum rod body with protective sleeves, creates a narrow gap between two adjacent aluminum rod bodies, preventing contact and wear between the two aluminum rod bodies. Furthermore, the multiple mounting planes on the outer ring surface of the protective sleeves facilitate the neat placement of adjacent aluminum rod bodies. This further solves the problem of collision and wear when stacking aluminum rods, ensuring that the aluminum rods are neatly placed while preventing collision and wear between adjacent aluminum rods.

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] Please see Figures 1-2This invention provides a technical solution: a high-strength corrosion-resistant aluminum rod, comprising an aluminum rod body 1, the surface of which is coated with a high-strength anti-corrosion coating. Protective sleeves 2 are fitted at both ends of the aluminum rod body 1. Pre-reserved grooves 4 are formed on the surface of the protective sleeves 2. Multiple clamping handles 6 are movably inserted into the surface of the pre-reserved grooves 4. A rotating ring 11 is fitted inside the pre-reserved grooves 4. The rotating ring 11 presses against the clamping handles 6 to clamp the aluminum rod body 1. Multiple notches 12 are formed on the surface of the rotating ring 11. When the rotating ring 11 is rotated so that the notches 12 and the clamping handles 6 are aligned, the clamping handles 6... The aluminum rod body 1 is no longer clamped, and the outer ring surface of the protective sleeve 2 has multiple mounting planes 16. After the protective sleeve 2 is fitted on both ends of the aluminum rod body 1, there is a narrow gap between two adjacent aluminum rod bodies 1, which avoids contact between the two aluminum rod bodies 1 and causes bumping and wear. In addition, the multiple mounting planes 16 on the outer ring surface of the protective sleeve 2 facilitate the neat placement of two adjacent aluminum rod bodies 1. This further solves the problem of bumping and wear when stacking aluminum rods, and can ensure that the aluminum rods are neatly placed while avoiding bumping and wear between adjacent aluminum rods.

[0042] Example 2

[0043] See attached document Figures 3 to 8 Based on Embodiment 1, in order to fix the protective sleeve 2 onto the aluminum rod body 1, the protective sleeve 2 has a circular ring plate structure. One end of the protective sleeve 2 is fixed with a sealing plate 3, the diameter of which is smaller than the outer diameter of the protective sleeve 2. There are four mounting planes 16, which are arranged in a cross shape. The reserved groove 4 is an annular groove, and multiple insertion ports 5 are opened on the surface of the reserved groove 4. The insertion ports 5 and the clamping handles 6 correspond one-to-one. The clamping handles 6 are movably inserted into the insertion ports 5. The end of the clamping handles 6 facing the reserved groove 4 has two bevels 10, which are arranged in a figure-eight shape. The other end of the clamping handles 6 has an arc-shaped curved surface, and openings are made on the arc-shaped curved surface. There is a notch 7, and a rubber traction belt 8 is fixed in the center of the notch 7. The two ends of the rubber traction belt 8 are respectively fixed on two parallel side walls of the insertion port 5, and a rubber pad 9 is fixed on the arc-shaped curved surface. When the rotating ring 11 squeezes the clamping handle 6 to clamp the aluminum rod body 1, the rubber traction belt 8 is in a state of tension deformation. A retaining ring 14 is fixed inside the reserved groove 4. A rubber ring 15 is fixed on the side of the retaining ring 14 facing the rotating ring 11. The rubber ring 15 is clamped between the rotating ring 11 and the retaining ring 14 and produces elastic deformation. The outer ring surface of the rotating ring 11 is provided with finger grooves 13. There are multiple finger grooves 13, and the multiple finger grooves 13 are arranged at equal distances and of equal size along the outer ring surface of the rotating ring 11.

[0044] Appendix Figure 4The protective sleeve 2 is securely installed at the end of the aluminum rod body 1. At this time, the notch 12 and the clamping handle 6 are misaligned, meaning that the rotating ring 11 squeezes the clamping handle 6 to clamp the aluminum rod body 1. The rubber traction belt 8 is also stretched and deformed by the clamping handle 6. The reason for adding a rubber ring 15 to the surface of the retaining ring 14 is that after the rotating ring 11 squeezes the rubber ring 15, the rebound force of the rubber ring 15 supports the rotating ring 11 against the side wall of the pre-reserved groove 4. At this time, there are no gaps between the two sets of rotating rings 11, meaning that the rotating ring 11 will not rotate unless propelled by an external force. When the aluminum rod body 1 is transported to the usage site… The protective sleeve 2 can be removed and reused. The specific operation is as follows: insert your finger into the finger groove 13 and rotate the rotating ring 11 around the reserved groove 4 until the notch 12 and the clamping handle 6 are opposite each other. At this time, the rubber traction band 8 rebounds and pulls the clamping handle 6 to move outward of the insertion port 5. One end of the clamping handle 6 is inserted into the notch 12. At this time, the clamping handle 6 no longer clamps the aluminum rod body 1. The protective sleeve 2 can be pulled away from the end of the aluminum rod body 1. This further solves the problem of collision and wear when stacking aluminum rods. It can ensure that the aluminum rods are neatly arranged while avoiding collision and wear between adjacent aluminum rods.

[0045] Example 3

[0046] See attached document Figure 9 and Figure 10 Based on Embodiment 2, in order to limit the two sets of stacked aluminum rod bodies 1, an assembly block 17 is fixed on the surface of the mounting plane 16 at the top of the protective sleeve 2, and an assembly groove 18 is opened on the surface of the mounting plane 16 at the bottom of the protective sleeve 2. The assembly groove 18 and the assembly block 17 match. When the two sets of aluminum rod bodies 1 are stacked, the assembly block 17 at the top of one set of protective sleeve 2 is inserted into the assembly groove 18 at the bottom of the other set of protective sleeve 2.

[0047] Furthermore, the length of the long side of the assembly slot 18 is less than the width of the mounting plane 16. Thus, after the two aluminum rod bodies 1 are stacked, the protective sleeves 2 corresponding to the two sets of aluminum rod bodies 1 are assembled by the assembly block 17 and the assembly slot 18, and there will be no problem of horizontal sliding. This further solves the problem of collision and wear when stacking aluminum rods, and can ensure that the aluminum rods are neatly arranged while avoiding collision and wear between adjacent aluminum rods.

[0048] Example 4

[0049] See attached document Figure 11 and Figure 12Based on Embodiment 3, in order to achieve the limiting of the two sets of aluminum rod bodies 1 when placed side by side, a slot 19 is opened on the surface of the mounting plane 16 on one side of the protective sleeve 2. The slot 19 is an arc-shaped groove. An guide strip 20 is fixed on the surface of the mounting plane 16 on the other side of the protective sleeve 2. A rubber clip 21 is sleeved on the end of the guide strip 20 away from the mounting plane 16. The rubber clip 21 is an arc-shaped strip. The rubber clip 21 matches the slot 19. When the two sets of aluminum rod bodies 1 are assembled side by side, the rubber clip 21 on the surface of one set of protective sleeve 2 is inserted into the slot 19 on the surface of the other set of protective sleeve 2. In this way, after the two aluminum rod bodies 1 are placed side by side, when there is no external tension, the protective sleeves 2 corresponding to the two sets of aluminum rod bodies 1 are engaged by the rubber clip 21 and the slot 19, which facilitates the neat placement of multiple sets of aluminum rod bodies 1 side by side. This further solves the problem of collision and wear when the existing aluminum rods are stacked. It can ensure that the aluminum rods are placed neatly while avoiding collision and wear between adjacent aluminum rods.

[0050] Example 5

[0051] Based on Example 4, in order to prepare a high-strength anti-corrosion coating, the raw materials for the high-strength anti-corrosion coating include, by weight: 58-59 parts modified epoxy resin, 11-12 parts polyurethane resin, 16-17 parts cellulose acetate, 53-54 parts organic solvent, 1.6-1.7 parts pigment, 0.6-0.7 parts defoamer, 0.9-1.1 parts leveling agent, 0.08-0.09 parts mildew inhibitor, 4.4-4.6 parts modified attapulgite, 2.6-2.8 parts calcined kaolin, 2.6-2.7 parts talc, 0.6-0.7 parts aluminum-zirconium coupling agent TL-2, 0.63-0.67 parts hydrogenated castor oil, 0.24-0.33 parts ferric chloride, and 0.08-0.09 parts cobalt octanoate.

[0052] Mix 68-72 parts by weight of epoxy resin and 29-33 parts by weight of styrene-butadiene-styrene block copolymer (SBS) evenly. Then add 47-50 parts by weight of mixed solvent, which consists of ethyl acetate and butyl acetate in a volume ratio of 6-7:1-2. Next, add 1.5-1.8 parts by weight of 2,5-dimethyl-2,5-bis(tert-butylperoxide)hexane, 0.4-0.5 parts by weight of sulfur, 0.2-0.3 parts by weight of zinc acrylate, and 0.1-0.3 parts by weight of 2,6-di-tert-butyl-4-methylphenol. Stir at 425-445 rpm. During stirring, raise the temperature to 90-93°C at a rate of 13-15°C / min, and then raise the temperature to 124-127°C at a rate of 0.5-0.8°C / min. After being heated for 5-6 hours, the modified epoxy resin was cooled to room temperature to obtain the modified attapulgite. In the preparation of the modified attapulgite, nano-attapulgite was placed in water and ultrasonically treated for 21-24 minutes to obtain 4.2-4.5 wt% material A. The ultrasonic treatment frequency was 16-20 kHz, the ultrasonic treatment power was 750-900 W, and the ultrasonic treatment pulse time was (5-7 s, 9-11 s). Material A and phytic acid were added to the inner liner of the hydrothermal reactor. The weight ratio of material A to phytic acid was 2-3:5-7. 0.1-0.2 mol / L sodium carbonate solution was added dropwise until the pH was 7-9. After sealing, the reactor was placed in an oven. The oven temperature was raised to 150-153℃ at an average heating rate of 7-10℃ / min and kept at that temperature for 92-95 hours. After cooling to room temperature, the modified attapulgite was obtained.

[0053] Example 6

[0054] A method for preparing a high-strength corrosion-resistant aluminum rod includes the following steps:

[0055] S1: Weigh the raw materials according to the mass percentage of each component in the high-strength corrosion-resistant aluminum rod;

[0056] S2: Melt the raw materials by heating to obtain molten aluminum;

[0057] S3: When the temperature of the molten aluminum reaches 750℃-770℃, the molten aluminum is refined to obtain refined molten aluminum.

[0058] S4: Let the refined aluminum liquid stand and cool down;

[0059] S5: Cool the refined aluminum liquid to 690℃-710℃, refine it using AlTi5C0.18 wire, degas it, filter it to remove impurities, and obtain the refined aluminum liquid.

[0060] S6: The refined aluminum liquid is placed in a mold and cast under the conditions of casting temperature of 670℃-690℃, casting speed of 250mm / min-550mm / min, and cooling water quenching of 100ton / h-120ton / h to obtain a casting rod.

[0061] S7: The cast rod is subjected to T6 heat treatment to obtain a high-strength corrosion-resistant aluminum rod with a size of Φ35mm-90mm.

[0062] In actual use, attached Figure 4 The protective sleeve 2 is securely installed at the end of the aluminum rod body 1. At this time, the notch 12 and the clamping handle 6 are misaligned, that is, the rotating ring 11 squeezes the clamping handle 6 to clamp the aluminum rod body 1, and the rubber traction belt 8 is stretched and deformed by the clamping handle 6. The reason for adding a rubber ring 15 to the surface of the retaining ring 14 is that after the rotating ring 11 squeezes the rubber ring 15, the elastic force of the rubber ring 15 supports the rotating ring 11 against the side wall of the reserved groove 4. At this time, there is no gap between the two sets of rotating rings 11, that is, the rotating ring 11 will not rotate when there is no external force. After the aluminum rod body 1 is transported to the use site, the protective sleeve 2 is removed and reused. The specific operation is as follows: insert your finger into the finger groove 13 and rotate the rotating ring 11 around the reserved groove 4 until the notch 12 is reached. 2. Opposite to the clamping handle 6, the rubber traction belt 8 rebounds and pulls the clamping handle 6 to move outward of the insertion port 5. One end of the clamping handle 6 is inserted into the notch 12. At this time, the clamping handle 6 no longer clamps the aluminum rod body 1, and the protective sleeve 2 can be pulled away from the end of the aluminum rod body 1. Furthermore, the length of the long side of the assembly groove 18 is less than the width of the installation plane 16. Thus, after the two aluminum rod bodies 1 are stacked, the protective sleeves 2 corresponding to the two sets of aluminum rod bodies 1 are assembled by the assembly block 17 and the assembly groove 18, and there will be no problem of horizontal sliding. After the two aluminum rod bodies 1 are placed side by side, when there is no external tension, the protective sleeves 2 corresponding to the two sets of aluminum rod bodies 1 are engaged by the rubber clip 21 and the clip groove 19, which makes it easy for multiple sets of aluminum rod bodies 1 to be placed side by side neatly.

[0063] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
