The mounting frame 2 is in threaded connection with the roller seat 3.
At present, a coiler belt coiling assisting device generally adopts a shovel plate structure, the shovel plate plays a basic role of coiling assisting, but the problems of tower type, staggered layers, broken angles, folds and the like often occur in strip steel coiling due to the fact that the minimum clearance between the shovel plate and a coiler winding drum is too large, the clearance between the shovel plate and a belt steering roller is large, and right-angle protrusions on two sides of the shovel plate have large deviation limitation on wide strip steel, and normal production of strip steel coiling is greatly influenced.
Therefore, the design concept of the application is to redesign the wrapper assisting mechanism, and utilize the roller to replace the shovel plate, so as to solve the series of problems, and the innovation point of the application is as follows: the design of the shovel plate of the original wrapper is changed, the supporting roller with the belt steering function is additionally arranged, and the wrapper function of the belt wrapper is optimized and improved by utilizing the foundation and the function of the original equipment.
The problems existing at present are as follows:
as shown in fig. 2, a coiler mandrel is wrapped by a coiler-aid belt, strip steel passes through a shovel plate to complete a circle after penetrating, the wrapping angle of the mandrel belt is small, the strip steel cannot be attached to the coiler mandrel when a strip head passes through a position without belt wrapping, the gap is too large, and after the coiling speed is increased and the coiling weight is increased, the inner ring has a gap, and sliding exists between layers to cause tower-shaped staggered layers;
as shown in fig. 4, when coiling and threading, the head of the strip steel needs to pass through the gap transition between the belt steering roller of the coiling aid and the shovel plate, and because the gap is too large and cannot be adjusted, the head of the strip steel is easily inserted into the gap, the thick material can be folded, and the thin material can cause wrinkles;
as shown in fig. 6, when the strip steel head passes through the shovel plate of the wrapper during coiling and threading, because the edge part of the shovel plate is designed with an edge part right-angled protrusion, when a width raw material is produced, if the strip steel head deviates, the strip steel head can impact the protrusion part to cause a break angle, and the strip steel head needs to be rewound and cut off to coil and thread the strip steel again.
The application has the advantages that:
the wrap angle of a belt of the coiling aid to a coiling block is increased through design and modification, and the layer clearance of a steel coil during coiling is reduced or even eliminated, so that the tower shape and the staggered layer of the strip steel are avoided;
the design and the transformation avoid the gap transition when the strip steel passes through the coiler, and prevent the problems of the head part of the strip steel such as the break angle and the fold;
the edge bulge of the shovel plate of the belt wrapper is eliminated through design and modification, and the problem that the strip head is folded when the strip steel is coiled is solved.
The method comprises the following specific steps:
the method comprises the following steps of designing a roller seat roller according to the installation position and mode of an original shovel plate by utilizing the original equipment layout, installing the roller seat roller at the position of the original shovel plate, and synchronously adjusting the length (increased from 10235mm to 10500mm) of a wrapper belt and the stroke (increased from 1000mm to 1180mm) of a wrapper belt tensioning oil cylinder due to the change of the belt steering position and the increase of the wrap angle of a coiler mandrel;
first, as shown in fig. 1 and 2, the winding drum part of the original designed coiler is wrapped by a wrapper belt, the band steel penetrates through a shovel plate to complete a circle, the wrapping angle of the wrapper belt before transformation is small, the band steel cannot be attached to the winding drum when the band head passes through a position without the belt wrapping, the gap is too large, the winding speed is increased, the inner ring after the winding weight is increased is provided with a gap, sliding exists between layers to cause tower-shaped staggered layers, after transformation, the length of the wrapper belt is increased, the belt finally turns through a newly transformed roller wheel, the wrapping angle of the winding drum belt is increased, and the band steel can be completely attached to the winding drum to complete winding.
Second, as shown in fig. 3 and 4, when the strip steel head needs to pass through the gap between the belt steering roller and the shovel plate during coiling and threading in the original design, because the gap is too large and cannot be adjusted, the strip steel head is easily inserted into the gap, a break angle can appear, a thin material can cause wrinkles, the strip steel head needs to be reversed and cut off to thread the strip again, the shovel plate is changed into a roller after transformation, the belt is steered by the roller and completely wraps the winding drum, the strip steel head does not need to pass through the gap, and the break angle or the wrinkles disappear.
Third, as shown in fig. 5 and 6, the strip steel head passes through the shovel plate when the strip steel is threaded in the original design, because the edge part 1520mm in the middle of the shovel plate is designed with the edge part right-angled bulge, when 1500mm wide raw materials are produced, if the strip steel is threaded and deviated by more than 10mm, the strip steel head can impact the bulge part to cause a break angle, the strip steel needs to be rewound and threaded again after being cut off, the design of the shovel plate is cancelled after transformation, the roller is changed into the roller, the edge part bulge is eliminated, and the break angle caused by the strip steel threading deviation is avoided.
The benefits after trial operation after reconstruction: 3.45+73.15 ═ 76.6 ten thousand;
the basis of calculation is as follows:
1. the product quality benefit is as follows:
and performing accounting by referring to the related data of 10 months to 2020 months in 2019, wherein the total quantity of the average related strip steel quality problems accounts for one ten thousandth of the yield in the current month.
According to the 5# black flat line monthly yield of 12 ten thousand tons, the average reject rate of the quality problem t of the reject products caused by the wrapper is 0.01 percent, after technical improvement is implemented, 80 percent of the reject can be reduced by one ton, and the price of the reject products is 300 yuan higher than that of qualified products.
The benefits are as follows:
the single month benefit is 120000 × 0.01% × 80% × 300 ═ 2880 yuan;
the annual benefit is 2880 x 12 ═ 34560 yuan.
2. Yield benefit:
and performing accounting by referring to relevant data of 10 months to 2020 months in 2019, wherein the average yield influenced by the accident time caused by the design defect of the wrapper shovel head is 304.8 tons per month, and the calculation is performed according to 200 yuan per ton of steel benefit.
The benefits are as follows:
the single month benefit is 304.8 x 200-60960 yuan,
the annual benefit is 60960 × 12 ═ 731520 yuan.
