Abstract
The utility model relates to an elastic sleeve for a cold-rolled strip steel uncoiler/coiler mandrel, which is capable of decreasing strip steel scratches and strip head marks. The inner diameter of the elastic sleeve is 1-5mm smaller than the contraction outer diameter of the uncoiler/coiler mandrel, the wall thickness of the elastic sleeve made of polyurethane ranges from 25mm to 80mm, and the shore hardness of the elastic sleeve ranges from 55 to 75. The elastic sleeve for the cold-rolled strip steel uncoiler/coiler mandrel is extremely convenient in installation, a reel contacts an inner hole of a steel coil through the elastic sleeve during expansion, no obvious reel impression is generated on the surface of strip steel basically, scratches of different degrees and reel impressions on strip steel heads are decreased to the maximum limit, loss of the strip steel is reduced greatly, and economic benefits are extremely obvious.
Description
Technical field
The utility model relates to a kind of cold-strip steel uncoiler/coiling machine annex, and specifically, the utility model relates to the resilient sleeve that a kind of cold-strip steel uncoiler/coiler mandrel is used.
Background technology
In the cold-reduced sheet production process, because the band steel has certain thickness, in uncoiling and coiling process, can cause wiping in various degree to scratch (spool seal) and belt end seal, and (steel) take the lead an impression that is produced in rolling up, in volume, there are tens meters, or even 100-200 rice.Along with the increase of the expensive goods demand of Automobile Plate, tame electroplax, silicon steel plate, packaging for foodstuff plate, each user is also more and more higher to the requirement of product made from steel quality, and this part cold-reduced sheet that has impression can only go out of use, and has caused a large amount of wastes.At present, domestic and international cold rolling industry reduces in the steel plate production process for improving plate quality, uncoiling or batch the wiping that causes and scratch (spool seal) and belt end seal, and general the employing increases directly plate or rubber bush, but really reaches perfect condition seldom.
The utility model content
The purpose of this utility model provides a kind of band steel that can reduce and wipes the resilient sleeve that the cold-strip steel uncoiler/coiler mandrel of the generation of scuffing and belt end seal is used.
The purpose of this utility model is achieved in that
The resilient sleeve that a kind of cold-strip steel uncoiler/coiler mandrel is used, described resilient sleeve is the contraction external diameter little 1-5mm of internal diameter than uncoiler/coiler mandrel, wall thickness is the polyurethane sleeve of 25-80mm, and the hardness of described resilient sleeve is Shao Er hardness 55-75 degree.
Further, the outer surface of described resilient sleeve is provided with positive and negative helix groove, and the inner surface of described resilient sleeve is evenly distributed with 8-28 bar axial groove.Described resilient sleeve one end endoporus is processed with interior chamfering, packs on uncoiler/coiling machine spool to make things convenient for resilient sleeve; Other end external process has outer chamfering, stretches into the coil of strip endoporus with the spool that conveniently installs resilient sleeve, and along with the spreading resilient sleeve of spool is followed tensioner, outer surface and coil of strip endoporus fit tightly guarantees not have skidding.
Wherein, the pitch of described positive and negative helix groove is 25-75mm, and groove depth is 2-6mm, and groove width is 2-8mm; The groove depth of described axial groove is 2-8mm, and groove width is 2-8mm; Chamfering is of a size of 10-30mm * 20 °-50 ° in described; Described outer chamfering is of a size of 10-30mm * 40 °-70 °.
The utility model is owing to adopted technique scheme, make it compared with prior art, have the following advantages and good effect: the resilient sleeve that the utility model cold-strip steel uncoiler/coiler mandrel is used is installed very convenient, spool is by the endoporus of resilient sleeve contact coil of strip in the harmomegathus process, belt steel surface can not produce tangible spool impression substantially, reduced band steel toe wiping scuffing and spool impression in various degree to greatest extent, greatly reduce the loss of band steel, economic benefit is fairly obvious.
Description of drawings
To embodiment of the present utility model and in conjunction with the description of its accompanying drawing, can further understand the purpose of this utility model, specific structural features and advantage by following.Wherein:
The structural representation of the resilient sleeve that Fig. 1 uses for the utility model cold-strip steel uncoiler/coiler mandrel;
Fig. 2 is a side view embodiment illustrated in fig. 1;
Fig. 3 is the I-I partial enlarged drawing of Fig. 1;
Fig. 4 is the II-II partial enlarged drawing of Fig. 2;
The user mode reference diagram (before the resilient sleeve tensioner) of the resilient sleeve that Fig. 5 uses for the utility model cold-strip steel uncoiler/coiler mandrel;
The user mode reference diagram (after the resilient sleeve tensioner) of the resilient sleeve that Fig. 6 uses for the utility model cold-strip steel uncoiler/coiler mandrel.
The specific embodiment
As shown in Figure 1 and Figure 2, the resilient sleeve that a kind of cold-strip steel uncoiler/coiler mandrel is used, resilient sleeve 1 are that internal diameter is more smaller than the contraction external diameter of uncoiler/coiler mandrel, are 1mm in the present embodiment, wall thickness is the polyurethane sleeve of 60mm, and the hardness of resilient sleeve 1 is Shao Er hardness 70 degree.The outer surface of resilient sleeve 1 is provided with positive and negative helix groove 11 (in conjunction with shown in Figure 3), and pitch is 50mm, and groove depth is 2mm, and groove width is 4mm; The inner surface of resilient sleeve 1 is evenly distributed with 16 axial grooves 12 (in conjunction with shown in Figure 4), and groove depth is 2mm, and groove width is 4mm.Resilient sleeve 1 one end endoporus are processed with interior chamfering 2, make things convenient for resilient sleeve 1 to pack on the spool 4 of uncoiler/coiling machine, and in the present embodiment, interior chamfering is of a size of 20 * 30 °; Other end external process has outer chamfering 3, and the spool 4 that conveniently installs the uncoiler/coiling machine of resilient sleeve 1 stretches in the endoporus of coil of strip 5, and in the present embodiment, outer chamfering is of a size of 20 * 60 °.
When the resilient sleeve of using when the utility model cold-strip steel uncoiler/coiler mandrel is used for uncoiler, resilient sleeve 1 is installed on the spool 4 of uncoiler, and spool 4 is tensioner not, as shown in Figure 5, between resilient sleeve 1 and the coil of strip 5 certain clearance is arranged, the endoporus that is beneficial to coil of strip 5 is easily packed on the spool 4 of uncoiler.Spreading along with the spool 4 of uncoiler, as shown in Figure 6, it is big that the external diameter of spool 4 becomes, the external diameter of the endoporus of resilient sleeve 1 and spool 4 is combined closely, continuation drives resilient sleeve 1 spreading along with the external diameter of spool 4 becomes big, and the external diameter of resilient sleeve 1 also fits tightly with the internal diameter of coil of strip 5, the endoporus of the outer surface of resilient sleeve 1 and coil of strip 5 fits tightly guarantees not have skidding, and spool 4 just can be rotated uncoiling work.After uncoiling finished, spool 4 shrank, because the material behavior of resilient sleeve 1, resilient sleeve 1 shrinks automatically and recovers reset condition.Just can repeat uncoiling work once more thereupon.
Otherwise, when the resilient sleeve of using when the utility model cold-strip steel uncoiler/coiler mandrel is used for coiling machine, in advance resilient sleeve 1 is installed on the spool 4 of coiling machine, and be in tensioner state (as shown in Figure 6), batch the work of band steel, batching spool 4 contractions (as shown in Figure 5) that finish the back coiling machine, just can unload volume work.
