Description
Technical Field
The utility model relates to an engineering machine tool field.
Background
The new bright line coiler is positioned at the tail end of the whole production line, and after the coiler jaw clamps the steel strip, the coiler drum rotates to coil the steel strip into a steel coil. When a jaw of the coiling machine clamps a steel belt and the steel belt is coiled tightly, due to the reaction force of the steel belt, after the steel belt is used for 1-2 months, the faults that a jaw layering screw is loosened and the jaw layering screw is broken easily occur, so that the problem that the jaw clamps the steel belt tightly and loosens coils is caused. The original jaw pressing strip is directly fixed on the sector plate, the jaw is not provided with a flange on the sector plate, and the jaw is easy to shake when pulled by the friction force of a steel belt, and is easy to loosen or break after a long time.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a prevent not hard up device of coiling machine jaw to the above-mentioned problem exactly.
The purpose of the utility model is realized like this: a device for preventing a jaw of a coiling machine from loosening comprises an upper jaw of the coiling machine, a lower jaw of the coiling machine, a first jaw pressing strip, a second jaw pressing strip, a third jaw pressing strip and a fourth jaw pressing strip, wherein the first jaw pressing strip and the second jaw pressing strip are steel plates with middle bulges; the third jaw pressing strip is arranged along the front end of the upper part of the lower jaw of the coiling machine, the other end of the third jaw pressing strip is connected with the fourth jaw pressing strip, and the fourth jaw pressing strip is arranged on the upper part of the lower jaw of the coiling machine.
Further, the first jaw pressing strip and the second jaw pressing strip are both 600-650mm long, the middle bulge is 15-35mm long, the two sides are both 5-15mm long steel plates, and the steel plates are uniformly provided with 3-9 threaded holes with the diameters of 10-15mm and arranged on the upper jaw of the coiling machine through bolts.
Further, the third jaw pressing strip and the fourth jaw pressing strip are both steel plates with the length of 600-650mm and the width of 35-55mm, and 3-9 threaded holes with the diameter of 10-15mm are uniformly formed in the steel plates and are arranged on the lower jaw of the coiling machine through bolts.
Furthermore, the groove is a groove with a groove depth of 5-10mm, a length of 1200-1500mm and a width of 15-35 mm.
The utility model has the advantages that:
1. the jaw of the recoiling machine is clamped to clamp the steel strip more firmly, so that the time and the raw materials are saved.
2. The faults of loosening of the jaw pressing strip screw and breakage of the jaw pressing strip screw are avoided.
3. Avoiding quality coils caused by the looseness of the jaw.
4. Before improvement, the newly brightly produced steel coil has 2-3 quality coils of loose steel strips every 1-2 months, the quality coils avoided each year are about 15 coils, and the benefit is about 30 ten thousand yuan.

Wherein: 1. the device comprises a groove, 2, mounting positions of a first jaw pressing strip and a second jaw pressing strip, 3, mounting positions of a third jaw pressing strip and a fourth jaw pressing strip, 4, an upper jaw of a coiling machine and 5, a lower jaw of the coiling machine.
Detailed Description
In order to avoid loosening of the jaw pressing strip, the structural form of the jaw pressing strip and the base of the coiling machine is changed, the installation form of the jaw pressing strip and the base is changed, an embedded jaw device is newly designed, the fault that the jaw pressing strip is separated from the base is eliminated, and therefore the quality coiling problem of the coiling machine of the bright annealing line is solved. The device changes the structural forms (shown in the figure) of the jaw pressing strip and the upper and lower jaw bases of the coiling machine, changes the jaw pressing strip into an embedded type, and fixes the jaw pressing strip into the groove of the base by screws. When the steel belt is clamped by the clamping strip jaw pressing strip and the steel belt is subjected to the force of pulling the steel belt out, the jaw is prevented from shaking back and forth by the embedded structure, so that the loosening fault is eliminated. In addition, the former threaded hole is enlarged, and an internal hexagonal screw with the diameter of 8mm is changed into an internal hexagonal screw with the diameter of 12mm, so that the pretightening force for compressing the jaw is larger, and the screw is further prevented from loosening. The improved jaw pressing strip is not loosened any more, and the problem of loosening of the jaws of a new bright line coiling machine is eliminated. At present, the design method is applied to a new bright line coiler, and the quality problem of over-coiling and untightening steel strips does not occur in about one year after installation.
The design of the device avoids the problem of loosening of the jaws of the coiling machine by changing the installation mode and the fixing mode of the jaws of the coiling machine, and avoids quality coils caused by loosening of the jaws.
The above description is only for the specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art can make changes or modifications within the scope of the present invention.
