Description
Technical Field
The invention relates to a guide ring, in particular to a guide ring for a sleeve.
Background
In the continuous production process of galvanized sheets for automobiles, it is generally necessary to insert a steel coil into a reel of an uncoiler at the inlet end of a production line so as to be uncoiled for production. Because the rigid contact between general sheet metal coil of strip inner circle and the decoiler reel, in order to protect the coil of strip, prevent that the coil of strip inner circle from producing the impression, generally install the sleeve on the decoiler reel first, the sleeve material generally is the rubber material, then insert the coil of strip on the sleeve again.
Fig. 1 to 3 illustrate a process of mounting a sleeve on a reel of an unwinder and a process of inserting a steel coil into the sleeve in the related art. Fig. 1 is a schematic view of a prior art unwinder drum without a sleeve mounted thereon. Fig. 2 is a schematic view of a prior art uncoiler drum with a sleeve mounted thereon. Fig. 3 is a schematic view of a steel coil insertion sleeve in the prior art. As shown in fig. 1, 2, and 3, in order to protect the steel coil 4, usually, before the steel coil 4 is inserted into the uncoiler drum 1, the sleeve 2 is attached to the uncoiler drum 1, and then the steel coil 4 is inserted into the rotating sleeve 2. The uncoiler winding drum 1 drives the expansion and contraction of the sleeve 2 through the expansion and contraction of the sector blocks 3 so as to achieve the purpose of fixing the uncoiler winding drum and the inner ring of the steel coil 4.
In the prior art, before the steel coil is inserted into the sleeve, the outer diameter of the sleeve is usually 580mm, and the diameter of the innermost ring of the steel coil is usually about 610mm, so the gap between the innermost ring of the steel coil and the sleeve is usually about 15 mm. However, because the steel plate of the innermost circle of the steel coil is often loose with the tape tail (as shown in fig. 4), thereby causing the diameter of the innermost circle of the steel coil to be often less than 610mm, when the steel coil is inserted into the reel of the uncoiler in rotation, the innermost circle of the steel coil can interfere with the conical end surface of the sleeve, and the friction coefficient of the rubber is large, thereby causing the steel plate of the innermost circle of the steel coil to slide out of the inner circle, and finally causing the failure of inserting the steel coil.

Detailed Description
The synchronous expansion and contraction guide ring for a sleeve according to the present invention will be further described with reference to the following embodiments and the accompanying drawings, but the description should not be construed as unduly limiting the technical solution of the present invention.
Fig. 5 is an exploded view of the synchronous expansion and contraction guide ring for the sleeve according to an embodiment of the present invention. Figure 6 further illustrates the structure of the sector of figure 5.
As shown in fig. 5 and 6, the synchronous expansion and contraction guide ring in the present embodiment has a first end surface a and a second end surface B in the axial direction, wherein the diameter of the first end surface a is larger than that of the second end surface B, so that the synchronous expansion and contraction guide ring is tapered in shape to match the tapered end surface of the sleeve when it is used for the sleeve. Further, the synchronous expansion and contraction guide ring in the present embodiment includes the segments 5 provided in the circumferential direction thereof, and the number of the segments 5 may be 4, and the 4 segments collectively enclose the synchronous expansion and contraction guide ring in the present embodiment. It should be noted here that in the present embodiment, the material of the segments 5 is metal, preferably stainless steel material, so that the friction coefficient of the synchronous expansion and contraction guide ring in the present embodiment is relatively small, and the hardness is relatively high, so that even if the steel coil interferes with the synchronous expansion and contraction guide ring in the present embodiment due to the loose tail of the inner ring during the coil inserting process, the loose tail can easily slip away without causing the loose tail to be pushed out of the steel coil. In addition, since the reel of the uncoiler usually drives the sleeve to expand or contract through the expansion or contraction of its own segment, in this embodiment, an elastic element is connected between two adjacent segments 5, which may specifically include: a first elastic member 6 provided on the first circumference C and a second elastic member 7 provided on the second circumference D so that the diameter of the synchronous expanding and contracting guide ring in the present embodiment can be relatively expanded or reduced with the relative expansion or reduction of the sleeve diameter to fit the sleeve. It should be noted here that the first circumference C and the second circumference D are both located on the inner wall of the synchronous expansion and contraction guide ring, and the diameter of the first circumference C is larger than that of the second circumference D. In some embodiments, both the first elastic element 6 and the second elastic element 7 may be tension springs.
It should be noted that, in the present embodiment, at the joint of the adjacent segments 5, the inner wall of the segment 5 is further provided with a guide tongue 16 extending along the circumferential direction thereof, so that the synchronous expansion and contraction guide ring in the present embodiment can form a closed structure along with the expansion and contraction of the sleeve, and furthermore, the guide tongue 16 is machined with a chamfer 23, so that the gap between the guide tongue 16 and the sleeve is reduced when the guide tongue 16 overlaps with another segment.
In addition, as can be seen from fig. 5 and 6, the inner wall of the synchronous expansion and contraction guide ring in the present embodiment has a plurality of positioning strips 8 protruding from the inner wall and distributed along the circumferential direction of the synchronous expansion and contraction guide ring, and each positioning strip 8 extends along the axial direction of the synchronous expansion and contraction guide ring, so that the synchronous expansion and contraction guide ring in the present embodiment can be embedded and matched with the corresponding positioning groove on the sleeve, thereby facilitating the synchronous expansion and contraction guide ring to expand and contract along the radial direction of the sleeve when the sleeve expands and contracts, but preventing the synchronous expansion and contraction guide ring and the sleeve from rotating relatively. In addition, in the embodiment, the inner wall of the synchronous expansion and contraction guide ring is also provided with positioning rings protruding from the inner wall, specifically comprises a first positioning ring 9 and a second positioning ring 10, wherein, it should be noted that, the radius of the circumference (i.e. the first circumference C) where the first positioning ring 9 is located is larger than the radius of the circumference (i.e. the second circumference D) where the second positioning ring 10 is located, both the first positioning ring 9 and the second positioning ring 10 extend along the circumferential direction of the synchronous expansion and contraction guide ring, so that the synchronous expansion and contraction guide ring in the embodiment can be embedded and matched with the corresponding positioning groove on the sleeve, therefore, when the synchronous expansion and contraction guide ring in the embodiment expands and contracts, the synchronous expansion and contraction guide ring provides circumferential guide for the synchronous expansion and contraction guide ring, can prevent the synchronous expansion and contraction guide ring from slipping along the inclined surface of the end part of the sleeve, and can also help the synchronous expansion and contraction guide ring in the embodiment to be fixed on the inclined surface of the end part of the sleeve. In this embodiment, the first retaining ring 9 and the second retaining ring 10 are provided with circular holes 15, so that the first elastic element 6 and the second elastic element 7 can pass through the circular holes 15, thereby achieving the connection between the adjacent segments 5.
In the present embodiment, the first positioning ring 9 and the second positioning ring 10 are respectively provided with a deformation slit 12 and a deformation slit 13 so that the synchronous expansion and contraction guide ring in the present embodiment can be appropriately deformed as the sleeve expands and contracts. Further, in the present embodiment, the second end surface B has an end wrap 11 extending radially inward from the inner wall of the synchronous expanding and contracting guide ring. The end wrap angle 11 is also provided with a deformation slit 14 so that the synchronous expansion and contraction guide ring in the present embodiment can be appropriately deformed as the sleeve expands and contracts. In addition, in the present embodiment, the two ends of the first positioning ring 9, the second positioning ring 10 and the wrap angle 11 are processed with circular chamfer angles 22, so that when the positioning ring and the rubber sleeve need to move relatively, the relative sliding between the two is facilitated.
Fig. 7 illustrates the insertion of the synchronous expansion and contraction guide ring for a sleeve according to the present invention in one embodiment with the end of the sleeve from a perspective. Fig. 8 illustrates another view of the synchronous expansion and contraction guide ring for a sleeve of the present invention in an embodiment in a manner of insert-fitting with the end of the sleeve. Fig. 9 is another view of the synchronous expansion and contraction guide ring for a sleeve of the present invention mounted on the end of the sleeve in one embodiment.
As shown in fig. 7, 8 and 9, and optionally in conjunction with fig. 5 and 6, the synchronous expansion and contraction guide ring for a sleeve according to the present invention is engaged with the end of the sleeve in an insertion manner:
when the synchronous expansion and contraction guide ring for the sleeve of the present invention is mounted to the sleeve 2, the first and second retainer rings 9 and 10 are respectively inserted into the first and second retainer ring grooves 20 and 21 of the sleeve 2, and the retainer strip 8 is inserted into the retainer strip groove 19, thereby preventing the synchronous expansion and contraction guide ring for the sleeve of the present invention from moving relative to the sleeve 2 in the axial and circumferential directions, and thus enabling the synchronous expansion and contraction guide ring to be stably mounted to the sleeve 2. In this mounted state, the first and second elastic elements 6 and 7 are respectively seated in the first and second elastic element grooves 17 and 18.
When the sleeve 2 expands and contracts in a state that the synchronous expansion and contraction guide ring is sleeved on the sleeve 2, the synchronous expansion and contraction guide ring and the sleeve 2 can synchronously expand and contract due to the fact that the first elastic element 6 and the second elastic element 7 are connected among the plurality of fan-shaped bodies 5 forming the synchronous expansion and contraction guide ring, and therefore guiding is provided for a steel coil inserted into the sleeve 2, and the problem that the steel coil is inserted into the sleeve to generate interference and cause coil insertion failure is effectively solved.
Therefore, the synchronous expansion and contraction guide ring for the sleeve is high in hardness and low in friction coefficient, can expand and contract along with expansion and contraction of the sleeve, and can effectively solve the problem that the coil inserting fails due to interference generated when a steel coil is inserted into the sleeve.
