Description

Technical Field

[0001] The utility model relates to cold-rolled steel bar production equipment, in particular to a cold-rolled wire coiling device, belonging to the technical field of machinery. Background Art

[0002] In the production of cold-rolled steel bars, a coiler (coiling device) is used when producing coils. After the steel bars are rolled into coils, they are tied with packing wires (packing tapes) and then transported out. The coilers currently used (generally with a cycloid for winding the wires one circle at a time) are generally driven by a motor, and the coiling adopts an expansion and contraction drum mechanism. The drum expands radially during coiling and contracts radially during unloading, so as to facilitate unloading of the rolled material coils. There are various mechanisms for reference in the prior art of expansion and contraction drums, such as CN105170700A. The expansion and contraction reel device is suitable for unwinding steel strips. It is also necessary to increase the design and function for winding wires. Chinese patent application No. 2018109413722 discloses a coil winding machine and a double-station winding system composed of the coil winding machine. The expansion and contraction reel relies on the conical head of the convex disc to extend into the interior of the reel to expand it. This has high requirements for the centering of the equipment manufacturing and installation. In the process of use, as the guide rail wears, the axis of the convex disc and the axis of the reel deviate or become larger, resulting in poor expansion and contraction. And the current winding machine is not easy to control during the manual threading of the strapping tape after the winding of a coil is completed. Summary of the invention

Four arc tiles 6 are respectively fixedly connected to the mounting seats on the corresponding axial beams, and the arc tiles are located outside the mounting plate 7. The inner ends of the two cranks on each axial beam are hinged on the first connecting rod 14, and the first connecting rod is hinged to one end of the second connecting rod 15. The hinge point of the two cranks on the same axial beam and the hinge point of the first connecting rod and the two cranks form a parallel four-bar linkage mechanism. The other end of the second connecting rod 15 is hinged on a fixed seat 16, and the fixed seat 16 is fixedly connected to the driving rod 4.
