Description

Technical Field:

[0001] The utility model relates to the field of wire and cable production equipment, and particularly relates to a novel double-disk take-up and reel-changing device for a large copper wire drawing machine. Background Art:

[0002] The double-disk take-up device of the large copper wire drawing machine has a two-center-point shaftless structure. One center point is driven to rotate by a motor through a synchronous toothed belt. Additionally, a shaft pin is carried on the take-up flywheel disk, and a spring is installed inside the shaft pin, so that it can freely stretch and automatically insert into the hole carried by the take-up reel (the shaft pin is fixed to the take-up flywheel disk). Thus, the take-up reel is driven to rotate together by the integral rotation of the center-point flywheel disk and the shaft pin. The other center point is driven by a cylinder to move linearly, and a protection interlock device is provided at the tail of the center point to prevent phenomena such as the take-up reel falling off due to sudden power failure or air supply interruption. The shaft-pin locking-disk structure drives the take-up reel to rotate. After long-term use, slight stringing friction occurs between the shaft pin and the disk hole, which easily causes the shaft pin to gradually deform and become smaller, thereby reducing the normal tangential force and finally causing the shaft pin to break, which is likely to cause equipment or personal safety accidents. When the turntable is driven to rotate by the shaft pin, before starting the machine, it is necessary to align the positions of the disk hole and the shaft pin to avoid misalignment of the shaft pin and leakage of locking, so a large amount of time is required to complete the operation during each reel-changing and loading process, thus reducing production efficiency and production capacity. In the production of the locking pin locking-disk structure, the frequency of replacing the worn shaft pin parts is high, resulting in corresponding increases in maintenance manpower and material resources, and increasing the maintenance cost. For this reason, the utility model proposes a novel double-disk take-up and reel-changing device for a large copper wire drawing machine to solve the deficiencies and drawbacks existing in the prior art. Content of the Utility Model:

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies existing in the prior art and provide a novel double-disk take-up and reel-changing device for a large copper wire drawing machine.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A novel double-disk take-up and reel-changing device for a large copper wire drawing machine includes a pair of take-up flywheel disks for fixing the take-up reel. An activity groove for the take-up reel to be positioned is provided on the front side of the take-up flywheel disk. A circular groove is also provided at the center position of the activity groove. A circular polyurethane friction disk is detachably installed in the circular groove. The circular polyurethane friction disk is annular. A center point is provided at the center position of the take-up flywheel disk, and the center point is located at the middle position of the circular polyurethane friction disk.

[0006] Preferably, the circular polyurethane friction disk is provided with counterbore holes and mounting holes. The circular polyurethane friction disk is detachably and fixedly installed on the take-up flywheel disk through fixing bolts passing through the counterbore holes and into the mounting holes.

[0007] Preferably, the inner diameter of the circular groove is not less than the outer diameter of the circular polyurethane friction disc.

[0008] Preferably, tips are provided on both of the wire-receiving flywheel discs, and the tips abut against the wire-receiving disc.

[0009] The beneficial effects of the present utility model are as follows:

[0010] The structure of the present utility model can well solve the phenomenon that when there is crosstalk between the shaft pin and the disc tool during the production process, the shaft pin breaks due to the rotational inertia of the wire-receiving disc; the circular polyurethane friction disc lock disc production provided by the present utility model reduces the difficulty of aligning holes when the shaft pin is mounted on the disc, reduces the replacement of accessories such as shaft pins, improves production efficiency, and at the same time avoids the occurrence of safety accidents such as equipment caused by the breakage of the shaft pin.

[0016] The drawings are only for illustrative purposes and cannot be construed as a limitation to this patent; for better explaining this embodiment, some components in the drawings will be omitted, enlarged or reduced, and do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0017] Such as Figures 1-4As shown in the figure, a new type of double-disk wire-reeling and disk-changing device for a large copper wire-drawing machine includes a pair of wire-reeling flywheel disks 001 for fixing the wire-reeling disk 002. An activity groove 003 for positioning the wire-reeling disk 002 is provided on the front side of the wire-reeling flywheel disk 001. A circular groove 004 is also provided at the central position of the activity groove 003. A circular polyurethane friction disk 005 is detachably installed in the circular groove 004. The circular polyurethane friction disk 005 is annular. A center point 006 is provided at the center position of the wire-reeling flywheel disk 001, and the center point 006 is located at the middle position of the circular polyurethane friction disk 005.

[0018] A further optimized setting of this solution is as Figures 1-4 shown in the figure: A counterbore 007 is provided on the circular polyurethane friction disk 005, and a mounting hole 008 is provided on the circular polyurethane friction disk 005. The circular polyurethane friction disk 005 is detachably and fixedly installed on the wire-reeling flywheel disk 001 through a fixing bolt 009 that passes through the counterbore 007 and enters the mounting hole 008.

[0019] A further optimized setting of this solution is as Figures 1-4 shown in the figure: The inner diameter of the circular groove 004 is not less than the outer diameter of the circular polyurethane friction disk 005, which facilitates the installation and replacement of the circular polyurethane friction disk 005.

When the device is in wire-reeling operation, after the center point 006 is inserted into the wire-reeling disk 002, its rubber contacts the wire-reeling disk over a large area, and the wire-reeling disk 002 is tightened by the friction between the rubber and the wire-reeling disk to achieve the locking effect of the wire-reeling disk 002.
