Description

Technical Field

[0001] The utility model relates to the technical field of steel cord production, and particularly relates to a limiting device for preventing steel wires from slipping off. Background Art

[0002] During the production process of steel cord, the steel wires need to go through multiple drawing processes. The drawing process is a metal plastic processing process in which a wire rod or wire blank is drawn out from the die hole of a drawing die under the action of a drawing force to produce steel wires or non-ferrous metal wires with a small cross-section. After the initial drawing is completed, the steel wires need to be arranged on the take-up frame in an orderly manner. The existing method is to wind the steel wires onto the drum of the take-up frame after passing through the straightener. There is an inclination angle in the winding direction of the steel wires on the drum. When winding, the latter circle of the steel wire pushes the former circle to wind forward until the entire drum is full.

[0003] In order to prevent the steel wires from being wound at the start of take-up, a limiting pressure block is arranged between the straightener and the drum. The steel wires pass through the limiting pressure block after being straightened by the straightener and then are wound around the drum. The tightly fitting steel wires on the drum are restricted by the limiting pressure block to avoid the phenomenon of wire entanglement, ensuring the smooth progress of subsequent intermediate drawing and wire release.

[0004] The existing limiting pressure block adjusts its relative position with the drum through a connecting rod and a screw. However, as the limiting pressure block wears, it will cause the limiting pressure block to be unable to effectively restrict the steel wires tightly fitting on the drum, and manual maintenance and adjustment are required in a timely manner. Otherwise, the effective control of take-up will be gradually lost, affecting the stability of take-up. Content of the Utility Model

[0005] The purpose of the utility model is to provide a limiting device for preventing steel wires from slipping off, which can keep the pressure of the pressure block on the steel wires continuously, prevent the effective control of take-up from being gradually lost due to wear, and effectively improve the stability of take-up.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: a limiting device for preventing steel wires from slipping off, including a mounting seat, a swing rod assembly is rotatably connected to the mounting seat. The swing rod assembly includes a rotating shaft sleeve, a first connecting rod and a second connecting rod are respectively connected to the rotating shaft sleeve. A vertical plate is arranged on one side of the mounting seat. At least one tension spring is connected between the vertical plate and the first connecting rod. When the tension spring pulls the first connecting rod, the second connecting rod keeps pressing down, and a pressure block is arranged on the second connecting rod.

[0007] A further improvement scheme of the utility model is that an avoidance opening is arranged on the vertical plate. An adjusting bolt with one end penetrating into the avoidance opening is arranged on the first connecting rod. A limiting nut is threadedly connected to the adjusting bolt. The diameter of the avoidance opening is larger than the diameter of the adjusting bolt and smaller than the diameter of the limiting nut. When the tension spring pulls the first connecting rod, the limiting nut abuts against the vertical plate.

[0008] A further improvement of the utility model is that at least one set of spring hooks are respectively arranged on the opposite surfaces of the vertical plate and the first connecting rod, and both ends of the tension spring are connected to the two spring hooks.

[0009] A further improvement of the utility model is that the mounting seat includes a base plate, a waist-shaped hole is arranged on the base plate, an adjusting plate is arranged on one side of the base plate, the adjusting plate is fixed on the base plate by a locking bolt passing through the waist-shaped hole, the vertical plate is arranged at one end of the base plate, and the rotating shaft sleeve is rotatably connected to the adjusting plate.

[0010] A further improvement of the utility model is that a rotating shaft is horizontally arranged on the plate surface of the adjusting plate, and the rotating shaft sleeve is rotatably connected to the rotating shaft.

[0011] A further improvement of the utility model is that the pressing block is detachably connected to the second connecting rod by bolts.

[0012] A further improvement of the utility model is that the included angle between the first connecting rod and the second connecting rod is less than 120°.

[0013] A further improvement of the utility model is that a protection mechanism is further arranged on the mounting seat, and the protection mechanism includes a threaded hole plate arranged on the side of the first connecting rod away from the vertical plate, and a limit bolt is threadedly connected to the threaded hole plate.

[0014] The beneficial effects of the utility model are as follows:

[0015] By arranging the tension spring, under the tension of the tension spring, the second connecting rod is continuously pressed down, so that the pressing block continuously maintains pressure to limit the steel wire. After the pressing block is worn, it can automatically press down under the action of the tension of the tension spring, realizing automatic compensation, preventing the effective control of wire winding from being gradually lost due to wear, and effectively improving the stability of wire winding.

[0016] An avoidance opening is arranged on the vertical plate of the utility model. By arranging the limit nut on the adjusting bolt to abut against the vertical plate, the range of the tension spring pulling the first connecting rod is limited. When the first connecting rod is pulled to a certain extent, it is restricted, and further the degree of the pressing block pressing down is limited, which is convenient for adjusting the pressure of the pressing block on the steel wire.

[0017] By arranging the protection mechanism, the rotation of the first connecting rod can be restricted by arranging the limit bolt, preventing the first connecting rod from rotating excessively clockwise after the tension spring accidentally detaches, resulting in the pressing block lifting and losing the restriction on the steel wire, and improving the safety of wire winding.

A threaded hole is provided on the vertical plate 5, and the adjusting bolt 8 is threadedly connected to the threaded hole on the vertical plate 5. One end of the rod portion of the adjusting bolt 8 can abut against the first connecting rod 3, thereby restricting the rotation of the first connecting rod 3.
