Description

Technical Field

[0001] This utility model belongs to the technical field of copper wire drawing equipment, and in particular relates to a mounting structure for the upper and lower plate fixed shafts of an automatic copper wire drawing take-up device. Background Technology

[0002] The existing structure uses a double-sleeve design, with the outer sleeve fixed by screws to the outer shell, restricting the axial freedom of the outer sleeve. "Copper drawing" refers to a process step in copper material processing, specifically the "drawing" stage in the stretching process of copper rods or wires. Automatic copper drawing and winding equipment enables automated loading and unloading of the wire reel. During automated loading and unloading, the reel is fixed by a combination of a fixed shaft and a movable shaft. To meet the requirements for automated loading and unloading of the copper drawing reel during winding, a movable shaft mounting structure is needed to fix the reel and drive its rotation for winding. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a movable shaft mounting structure for use in combination with a copper large-scale automatic take-up reel device.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a copper large take-up reel movable shaft with anti-rotation function, including a housing, a movable shaft assembly and an anti-rotation limiting assembly;

[0005] The movable shaft assembly consists of a bushing, a rotating shaft, an end cap, a guide ring, an end head, a first telescopic cylinder, a cylinder seat, a push plate, a first ball bearing, and a second ball bearing. The housing has a through hole with a limiting platform in the middle. Two guide rings are respectively installed inside the outer end of the through hole of the housing and abut against the limiting platform. The bushing is slidably installed inside the two guide rings. The cages of the two first ball bearings are fixedly installed inside the two ends of the bushing. The rotating shaft is fixedly installed inside the rotating body of the two first ball bearings. The end cap is fixedly installed on the right end of the bushing, and the end head is fixedly installed on the left end of the rotating shaft. The cylinder seat is fixedly installed on the housing. The cylinder body of the first telescopic cylinder is fixedly installed on the cylinder seat. The piston rod of the first telescopic cylinder is fixedly connected to the push plate. The rotating body of the second ball bearing is fixedly sleeved on the left end of the rotating shaft, and the push plate is fixedly sleeved on the cage of the second ball bearing.

[0006] Anti-rotation limit components are used to limit the rotation of the bushing.

[0007] Preferably, the anti-rotation limiting component consists of a first bearing seat, a second telescopic cylinder, a second bearing seat, and a guide rod. The first bearing seat and the second bearing seat are both fixedly installed on the housing. The lower end of the cylinder body of the second telescopic cylinder is hinged to the first bearing seat. The rear end of the guide rod is connected to the second bearing seat. The piston rod of the second telescopic cylinder is hinged to the middle of the guide rod. The upper and lower ends of the end cover are integrally formed with wing plates. The end cover is provided with a U-shaped guide groove that cooperates with the guide rod.

[0008] Preferably, the guide rod consists of a fixed rod and a movable rod. The rear end of the fixed rod is hinged to the second bearing seat, the piston rod of the second telescopic cylinder is hinged to the front end of the fixed rod, and the movable rod is screwed and fixedly installed at the front end of the fixed rod.

[0009] Preferably, the end is configured as a closed-bottom ring structure.

[0010] Compared with existing technologies, the advantages of this invention are: the movable shaft of the large copper take-up reel rotates only synchronously with the turntable of the empty reel and the fixed shaft assembly, while the bushing is in a non-rotating state with the anti-rotation limiting component. This avoids wear caused by relative rotation between the bushing and the guide ring, extending the service life of the movable shaft assembly. By setting a pneumatically liftable anti-rotation limiting component, the guide rod or the U-shaped guide groove of the end cover can be easily disassembled and replaced after wear, offering the advantage of easy maintenance.

[0016] The present invention will now be described in detail with reference to specific embodiments:

[0017] like Figures 1 to 4 The copper large take-up reel movable shaft with anti-rotation function shown includes a housing 1, a movable shaft assembly 2, and an anti-rotation limiting assembly 3;

[0018] The movable shaft assembly 2 consists of a bushing 20, a rotating shaft 7, an end cap 21, a guide ring 22, an end head 23, a first telescopic cylinder 4, a cylinder seat 41, a push plate 42, a first ball bearing 5, and a second ball bearing 6. The housing 1 has a through hole with a limiting platform in the middle. The two guide rings 22 are respectively installed inside the outer end of the through hole of the housing 1 and abut against the limiting platform. The bushing 20 is slidably installed inside the two guide rings 22. The cages of the two first ball bearings 5 ​​are fixedly installed inside the bushing 20. The shaft 7 is fixedly installed in the rotating body of the two first ball bearings 5, the end cap 21 is fixedly installed in the right end of the bushing 20, the end head 23 is fixedly installed in the left end of the shaft 7, the cylinder seat 41 is fixedly installed in the housing 1, the cylinder body of the first telescopic cylinder 4 is fixedly installed in the cylinder seat 41, the piston rod of the first telescopic cylinder 4 is fixedly connected to the push plate 42, the rotating body of the second ball bearing 6 is fixedly sleeved in the left end of the shaft 7, and the push plate 42 is fixedly sleeved in the cage of the second ball bearing 6.

[0019] The anti-rotation limiting component 3 is used to limit the rotation of the bushing 20.

[0020] The anti-rotation limiting component 3 consists of a first bearing seat 31, a second telescopic cylinder 32, a second bearing seat 33, and a guide rod 34. The first bearing seat 31 and the second bearing seat 33 are both fixedly installed on the housing 1. The lower end of the cylinder body of the second telescopic cylinder 32 is hinged to the first bearing seat 31. The rear end of the guide rod 34 is connected to the second bearing seat 33. The piston rod of the second telescopic cylinder 32 is hinged to the middle of the guide rod 34. The end cover 21 has wing plates 210 integrally formed at both ends. The end cover 21 has a U-shaped guide groove 211 that cooperates with the guide rod 34. When the piston rod of the second telescopic cylinder 32 extends, it pushes the guide rod 34 to move to a horizontal state. The guide rod 34 slides in the U-shaped guide groove 211 of the end cover 21, thus limiting the rotation of the combination of the end cover 21 and the bushing 20.

[0021] The guide rod 34 consists of a fixed rod and a movable rod. The rear end of the fixed rod is hinged to the second bearing seat 33. The piston rod of the second telescopic cylinder 32 is hinged to the front end of the fixed rod. The movable rod is screwed and fixedly installed at the front end of the fixed rod. After the movable rod wears out, it can be disassembled and replaced separately. When the U-shaped guide groove 211 of one side wing plate 210 of the end cover 21 wears out, the assembly of the end cover 21 and the bushing 20 is rotated 180° and the U-shaped guide groove 211 of the other side wing plate 210 is used. After the U-shaped guide grooves 211 of both wing plates 210 wear out, the end cover 21 is removed and replaced.

[0022] The end 23 is configured as a closed-bottom ring structure. The ring structure can cooperate with the end groove of the fixed shaft assembly. The ring structure can reduce the amount of material used, thereby reducing the weight of the outer end of the rotating shaft 7.

[0023] When the empty wire reel to be taken up is clamped and fixed on the fixed shaft assembly and the movable shaft assembly 2, the piston rod of the first telescopic cylinder 4 extends and pushes the assembly of bushing 20, end cover 21, rotating shaft 7 and end head 23 to slide outward along the guide ring 22. The bushing 20 passes through the center hole of the empty wire reel and supports it until the end head 23 of the rotating shaft 7 is engaged with the end head of the fixed shaft assembly and is radially fixed. After the empty wire reel is hung on the turntable of the fixed shaft assembly, there is a gap between the empty wire reel and the bushing 20. The rotating shaft 7 rotates synchronously with the turntable of the empty wire reel and the fixed shaft assembly. The bushing 20 is in a non-rotating state under the anti-rotation limit assembly 3 to avoid wear.
