Description

Technical Field

[0001] The invention relates to the field of metal material processing and manufacturing, and in particular to an assembly production method for a pallet made of recycled aluminum. Background Art

[0002] Recycled aluminum is also called "secondary aluminum". It is obtained by smelting scrap aluminum parts and scrap aluminum materials. At present, the annual production of recycled aluminum in the world is about 4 million tons, accounting for a considerable share of the production of primary aluminum. Compared with the production of electrolytic aluminum, the reuse of recycled aluminum can reduce the damage to land vegetation and consume only about 5% of the energy of electrolytic aluminum, so it is increasingly valued. However, during the recycling and remelting process of recycled aluminum, due to the high amount of impurities, in order to ensure the performance of the products produced by recycled aluminum, the purification and impurity removal during the smelting and casting of recycled aluminum is particularly important.

[0003] Cable reels are also called cable reels, cable trays, cable reels, etc. They are disc-shaped, with cables wound around the outer edge of the disc. The core of the reel is a shaft hole, which can be inserted into the shaft, and the reel can be erected to achieve free rotation and gradually extend the cable. The structure is simple, sturdy and durable. Traditional cable reels are made of steel-wood mixed materials or steel. After the angle steel roller is bent into a circular frame, the joints are welded and fixed, and then the circular frame is welded and fixed to the spokes. The flat part of the reel is usually filled with wooden boards.

[0004] Although the manufacturing cost of traditional cable reels is low, they still have the following disadvantages: 1. The part of the cable reel filled with wooden boards requires a large amount of wood, which is not in line with the concept of environmental protection; and the wooden boards are easy to rot in the outdoor environment, which affects the service life; 2. The use of a steel frame makes the overall weight of the cable reel heavier, which is inconvenient during transportation and handling, and consumes more manpower, material resources and energy; 3. Usually, the cable reel is more complicated and costly to repair after damage. Therefore, if the damage is more serious, the whole cable reel will be scrapped and the residual value will be low; 4. The cable reel needs to occupy a large amount of space for storage when it is empty, which is not conducive to reducing storage costs.

[0005] The prior art about aluminum alloy cable tray was retrieved: 1. An aluminum alloy cable reel structure; 201621294464.9; An aluminum alloy cable reel structure, comprising a steel supporting frame constituting the cable reel, a winding shaft frame and side frames arranged at both ends of the winding shaft frame are provided in the steel supporting frame, locking bolts for easy assembly and disassembly are provided between the winding shaft frame and the side frames, an integral winding disc sleeve is provided outside the winding shaft frame, an embedded circular groove is provided on the inner side of the two side frames, a smooth side plate disc is provided in the embedded circular groove, two positioning square holes are provided on the side plate disc, and positioning tenons matching the positioning square holes are provided at each end of the winding disc sleeve; the winding disc sleeve and side plate disc processed by the utility model have smooth surfaces, are suitable for batch manufacturing, no longer need to splice and nail wooden boards, reliable quality control, easy assembly and use, and low overall manufacturing cost; the cable surface protective layer is not easily damaged during production, transportation and use.

The utility model provides an aluminum alloy cable take-up drum, which adopts an arc hole and a fixed component arranged on the take-up drum to fix the head and the end of the cable well on the take-up drum, thereby ensuring the quality of the cable product.

[0007] Although some cable reels made of aluminum alloy are introduced in existing literature, they still have disadvantages such as low aluminumization, insufficient overall structural stability, and inconvenient disassembly. In addition, existing aluminum alloy reels still use welding structures in whole or in part, which will cause annealing of aluminum alloy connection nodes, resulting in a serious decrease in local strength and affecting the overall strength of the reel. Summary of the invention

[0008] The present invention provides a method for assembling and producing a pallet made of recycled aluminum. All main parts of the cable reel are made of aluminum profiles and assembled, which has the advantages of light weight, green environmental protection, and detachable assembly. All connection nodes are connected in a non-welding manner, thereby avoiding mechanical loss and having high overall strength.

[0009] In order to achieve the above objectives, the technical solution of the present invention is as follows: A method for assembling and producing a pallet made of recycled aluminum, wherein two ends of a drum shaft are connected to one end of a spoke, the end of the drum is fixedly connected to the middle of the spoke, and an outer disk frame is fixedly connected to the other end of the spoke; The profile section of the roll is a multi-cavity hollow profile, one of the cavities of which can be embedded with an insert, a through hole is provided on the insert, the position of the through hole matches the through holes on the upper and lower end surfaces of the profile, and the insert is fixed to the two ends of the roll profile with bolts; The insert is made of steel, and through holes are set on the upper and lower end faces of the insert. Bolts pass through the upper and lower surfaces and the through holes of the drum profile to fix the insert to the end of the inner cavity of the drum profile; threaded holes are set on the side of the insert, and bolts pass through the through holes of the spokes to fix the spokes close to the drum profile.

[0010] The outer disc frame profile is obtained by roller bending or press bending.

[0011] The assembly process includes the following steps: A. Place the drum shaft vertically, and connect one end of the drum shaft to the end of the spoke, and tighten the bolts to secure them; B. Connect the outer disc frame profile section by section with the other end of the spoke to form a complete outer disc frame ring, and tighten the bolts to fix it; C. Insert the blocks into the two ends of the inner cavity of the roll profile respectively, and fix them to the ends of the roll profile with bolts; D. Connect the drum profile piece by piece to the middle of the spoke, and anchor the spoke to the insert by bolts to finally form a ring-shaped drum; E. Install the spokes on the other end of the drum shaft and anchor the spokes to the insert with bolts; F. Connect the outer disc frame profile on the other side to the other end of the spoke section by section to form an outer disc frame ring on the other side, and tighten the bolts to fix it; G. Apply an insulating, pressure-resistant and weather-resistant coating on the surface of the drum to complete the assembly of the cable reel.

[0012] The reel surface coating can be made of polysilazane resin coating, which can be fully coated to prevent the reel surface from directly contacting the cable, protect the cable, and increase the life of the reel. The reel shaft is an extruded aluminum profile, and the cross-sectional shape of the profile is: a plurality of fixed limbs are radiated from the outer side of the round tube, the spoke ends are clamped in the middle of the fixed limbs, and bolts are passed through and anchored.

[0013] The spoke ends are anchored to the fixed limbs by bolts.

[0014] The reel is obtained by splicing a plurality of arc-shaped profiles end to end, and a through hole is arranged at the splicing position, which is anchored by bolts.

[0015] The plug-in profile ends can be better engaged and fixed, the curved profile will not be misplaced or deformed, and the overall stability is guaranteed.

[0016] The outer disc frame is obtained by splicing a number of arc-shaped profiles end to end. The cross-section of the outer disc frame profile is divided into a main body and a flange portion. The flange portion is located on the center line of the inner side of the main body. The overlapping portion of the profiles is spliced ​​as follows: the first profile is milled off half of the main body but the flange portion is retained, and the tail profile is milled off the other half of the main body but the flange portion is not retained.

[0017] The profile section of the outer disc frame is specially designed with an additional flange, which, on the one hand, enhances the radial deformation resistance of the profile; secondly, the flange increases the bolt anchoring area, making the fixation of the spokes and the outer disc frame more stable. The arc profile of the outer disc frame is connected end to end through the overlapping part, and the joint is more firm; because the flange is staggered with the main body, the weak point at the end joint of the profile is eliminated, improving the rigidity and stability of the outer disc frame.

[0018] At the position where the outer disc frame is connected to the spokes, the profile section of the outer disc frame is milled to remove half of the main body but retain the convex edge, and the formed groove plane is embedded with the spokes and then anchored with bolts.

[0019] The outer disc frame and the spokes are fastened with a mortise and tenon overlap structure, which ensures that the tangential stress between the outer disc frame and the spokes is well transmitted, preventing the bolts from bending and breaking due to excessive shear force.

[0020] At the position where the drum is connected to the spokes, a groove is milled on the profile cross-section of the drum, and the groove is embedded and connected with the spokes.

[0021] The drum and spokes are fastened with a mortise and tenon overlap structure, which allows the tangential stress between the drum and the spokes to be well transmitted, preventing the bolts from bending and breaking due to excessive shear force.

[0022] Advantages of the invention: 1. The present invention adopts recycled aluminum all-aluminum profiles to manufacture the cable reel, which overcomes the current situation that the traditional cable reel is made of materials such as wood boards, reduces the felling of forest trees, meets the current ecological and green development needs, and the aluminum alloy cable reel is superior to the existing cable reel in terms of moisture resistance, high temperature resistance, corrosion resistance, etc.

[0023] 2. The present invention utilizes recycled aluminum for remelting and casting, and the purification process and impurity removal process adopted are effective, thereby ensuring the impurity content in the aluminum body, thereby ensuring the mechanical properties and overall rigidity of the cable reel profile.

[0024] 3. The recycled aluminum alloy cable reel of the present invention has a lighter total weight. Compared with traditional cable reels of the same size, it is calculated that the weight can be reduced by more than 30%, which greatly reduces the transportation and lifting costs.

[0025] 4. The connection nodes of the all-aluminum cable reel of the present invention have no welding structure. Firstly, it can reduce the increase in production cost caused by the welding process; secondly, it avoids the loss of mechanical properties of aluminum alloy caused by high-temperature welding; thirdly, the bolt fastening is a reversible fastening form, which is more convenient for disassembly.

[0026] 5. The present invention can realize the standardization of cable reel components. When a part of the cable reel is damaged or deformed, it can be disassembled and the components can be replaced, thereby repairing the cable reel. The damaged parts can be 100% melted and recycled, greatly reducing the loss of resources. BRIEF DESCRIPTION OF THE DRAWINGS
