Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum processing, and in particular relates to a reel used for winding aluminum strips. Background Art

[0002] The finished aluminum coil is wound up with an aluminum core or paper core strip. With the long-term use of the reel, the wear and precision of its internal parts can easily cause the diameter expansion of the reel to be uncontrollable, causing the aluminum coil to slip during the winding process or the paper core of the finished roll to collapse. For the existing aluminum strip reel, first determine the diameter expansion size that needs to be adjusted, then adjust the relative position of the diameter adjusting nut through the diameter adjusting scale on the shaft head, move the diameter adjusting nut to the appropriate position, start the expansion and contraction cylinder to drive the core shaft to move horizontally until the free section of the core shaft and the diameter adjusting nut are against each other, at this time, the diameter expansion is adjusted to the target size. However, the shaft head bolts are prone to breakage due to the hydraulic shock of the expansion and contraction cylinder during the expansion process, causing the shaft head to fall off. The broken bolts are very likely to injure people, and the fallen shaft head is also likely to damage other equipment, seriously affecting production efficiency.

[0003] Therefore, it is urgent to design a reel with adjustable diameter expansion, strong stability and high safety. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a reel for winding aluminum strip, which is used to solve the problems of wear and precision reduction of internal parts of the reel, and easy breakage of shaft head bolts due to hydraulic impact of expansion and contraction cylinder during expansion, thereby improving product quality and production efficiency and reducing maintenance costs and safety risks.

[0006] Wherein, the positioning nut has various thickness specifications;

[0007] The reel is equipped with an expansion and contraction cylinder, which is used to drive the core shaft and the positioning nut to move horizontally along the reel body, thereby adjusting the relative position of the bow plate. When the expansion and contraction cylinder drives the positioning nut to abut against the reel body, the reel expands to the maximum diameter.

[0008] The utility model is further configured as follows: the number of the arc-shaped limiting plates and the number of the bow-shaped plates are both three.

[0009] The utility model is further configured as follows: the lower end of the plunger is configured in an inclined surface to match the inclined wedge groove.

A number of plungers 1 inserted into the core shaft 6 are arranged on the side of the arch plate 7 facing the reel body 11, and the number and spacing of the plungers 1 are the same as those of the disc springs 8, the lower end of the plunger 1 is arranged in an inclined surface, and the position of the core shaft 6 corresponding to the plunger 1 is provided with an inclined wedge groove 12, and the plunger 1 and the inclined wedge groove 12 are slidably matched. The left end of the reel body 11 is fixedly connected with a shaft head 2 , and the shaft head 2 is fixedly connected to the reel body 11 via a shaft head bolt 5 .

[0023] A diameter adjusting nut 4 facing the mandrel 6 is installed on the right side of the shaft head 2. The diameter adjusting nut 4 is retracted to the maximum limit and does not contact the mandrel 6. The diameter adjusting nut is used to limit the movement of the mandrel toward the shaft head, thereby limiting the further expansion of the reel. A positioning nut 9 threadedly connected to the mandrel 6 is provided at the right end of the reel body 11, and a nut step is provided on the left side of the positioning nut 9; a plurality of top screw holes are provided on the right side of the positioning nut 9, and the plurality of top screw holes are in geometrically equivalence with the shaft core 6, and top screws 10 are installed in the top screw holes.

[0024] Among them, the positioning nut 9 has a variety of thickness specifications;

When the expansion and contraction cylinder drives the positioning nut 9 to abut against the reel body 11, the reel expands to the maximum diameter.

[0026] The working principle of the utility model in the precise positioning of the reel expansion is as follows:

[0027] First, according to the production and diameter expansion requirements, select the positioning nut 9 of the corresponding thickness specification, then install the positioning nut 9 on the right end of the core shaft 6, and further fix it with the top screw 10 to prevent it from moving in the opposite direction under the action of internal force, to ensure the accuracy and stability of the expansion positioning, and then drive the core shaft 6 and the positioning nut 9 to move horizontally along the reel body 11 through the expansion and contraction cylinder until the left end of the positioning nut 9 is against the reel body 11, at this time, the diameter is adjusted to the target size. In the utility model, the diameter adjustment nut 4 is in the maximum avoidance position and does not contact the core shaft 6, so the shaft head bolt 5 is not subject to the diameter expansion force and is not easy to break, and the force acts on the positioning nut 9.

[0028] In summary, the utility model invention, by setting the positioning nut 9 and the top screw 10 structure, can accurately control the scale of the reel expansion diameter, and can withstand the lateral force applied by the expansion and contraction cylinder, thereby solving the accuracy and stability of the expansion positioning, and also solving the risk of the shaft head bolt 5 being easily broken when subjected to the lateral force.
