Abstract
The utility model provides a steel coil inner diameter expansion washer, which consists of a female ring, a gasket and a countersunk head bolt; the annular female ring is sleeved with a gasket, one side of the female ring and the gasket is provided with an opening, 3 bolt holes are correspondingly arranged at intervals of 90 degrees along the outer circumference of the female ring and the gasket, and the female ring and the gasket are connected together through countersunk bolts. When the coil of strip internal diameter exceeded the reel inflation limit, according to coil of strip internal diameter size, on the gasket combination to the mother circle with appropriate thickness, then use two gaskets to install on the reel as a set, the coil of strip of wider specification can be established and is counted when increasing the gasket group. Because the washer is added on the winding drum, the maximum expansion diameter of the winding drum is increased, and the flat winding defect of the coiled steel coil can be effectively avoided, so that the waste judgment loss is reduced, the yield of the strip steel is improved, and the production cost is reduced.
Description
Technical field
The utility model belongs to the rolling machinery connector, relates in particular to a kind ofly for adjusting the reel limit of expansion, realizes the packing ring of coil of strip internal diameter expansion.
Background technology
In the hot-strip production process, impact due to factors such as site technique condition variations, often there is the internal diameter of coil of strip to surpass the reel limit of expansion, cause the coil of strip after part is batched to have flat volume defect, steel coil heart ovalize, be not the normal circular roll heart, bring very big puzzlement to next procedure production, a lot of coil of strips because of can't rewinding and uncoiling production have to by sentencing useless processing, thereby had a strong impact on the lumber recovery of product, cause unnecessary economic loss.
Summary of the invention
The utility model provides a kind of coil of strip internal diameter expansion packing ring, is intended to effectively solve because the coil of strip internal diameter surpasses the flat volume defect that the reel limit of expansion causes, thereby improves band steel lumber recovery, reduces and sentences useless loss.
For this reason, the solution that the utility model is taked is:
A kind of coil of strip internal diameter expansion packing ring, be comprised of mother's circle, pad and countersunk bolt; The female circle of annular overcoat has pad, female circle and pad one side opening, and along female circle and pad excircle interval, 90 ° correspondingly are provided with 3 bolts hole, female enclose and pad links together by countersunk bolt.
Described A/F is 45-55mm.
Described female circle is identical with gasket width.
Using method of the present utility model and beneficial effect are:
When occurring that the coil of strip internal diameter surpasses the situation of reel limit of expansion, according to the coil of strip internal diameter size, the shim pack of suitable thickness is incorporated into to female circle upper, two packing rings of then take are installed to respectively on reel as one group, and the coil of strip of wider specification can be established when increasing the washer sets number.Owing to having increased packing ring on reel, be equivalent to strengthen the reel footpath of rising sharply most, thereby flat volume defect appears in the coil of strip after can effectively avoiding batching, reduce and sentencing useless loss, improve the lumber recovery with steel, reduce production costs.
The accompanying drawing explanation
Fig. 1 is the packing ring top view;
Fig. 2 is the I section profile of Fig. 1.
In figure: female circle 1, pad 2, opening 3, countersunk bolt 4.
The specific embodiment
As seen from Figure 1, the utility model coil of strip internal diameter expansion packing ring system by mother enclose 1, pad 2 and countersunk bolt 4 formed.Female circle 1 is annular with pad 2, on the top of annulus and 90 °, two side intervals respectively correspondence be processed with 1 bolt hole, and enclose 1 mother and leave with the bottom of pad 2 opening 3 that a width is 50mm, so that the installation of packing ring.Female circle 1 thickness 8mm, width 40mm; Pad 2 width are identical with female circle 1 width, and thickness can be selected as required, and embodiment thickness is 10mm.
During use, pad 2 is enclosed within to the outside of female circle 1, and is fixedly connected with (see figure 2) with 3 countersunk bolts 4 and gets final product together.
Claims (3)
1. a coil of strip internal diameter expansion packing ring, is characterized in that, mother's circle, pad and countersunk bolt, consists of; The female circle of annular overcoat has pad, female circle and pad one side opening, and along female circle and pad excircle interval, 90 ° correspondingly are provided with 3 bolts hole, female enclose and pad links together by countersunk bolt.
2. coil of strip internal diameter expansion packing ring according to claim 1, is characterized in that, described A/F is 45-55mm.
3. coil of strip internal diameter expansion packing ring according to claim 1, is characterized in that, described female circle is identical with gasket width.
