Abstract
The utility model discloses a rubber lined sleeve capable of reducing coiling crease and rubbing print on band steel, which comprises a steel sleeve. A polyurethane protection sleeve is connected outside the steel sleeve. The surface roughness of the polyurethane protection sleeve is Ra 8 to 10 and the rigidity of the polyurethane protection sleeve is HS being equal to 50 to 55. In the rubber lined sleeve disclosed by the utility model, an internal steel structure plays a support role and orange peel processing is carried out on the surface of the external polyurethane protection sleeve, which can ensure that friction force is enough between a first circle of band steel and the sleeve. Moreover, the rigidity of the polyurethane protection sleeve can ensure that the coiling crease can be eliminated and tenacity is enough for avoiding overquick abrasion. Meanwhile, reasonable rigidity ensures certain elasticity. A head of the band steel can sink into a rubber surface, therefore the rubbing print and the coiling crease on the surface of the band steel are reduced and the surface quality of the band steel is improved.
Description
Technical field
The utility model relates to a kind of can alleviating and is with the steel generation to batch the line with rubber sleeve of creasing with the rubbing seal.
Background technology
At present, the middle operation of stainless steel sheet strip production and product all exist with volume type state.In process of production, when jaw is nipped when beginning to batch by band steel toe portion, can crease, can produce the interlayer changing of the relative positions because of unit tension force is different during the next procedure uncoiling, form rubbing and print, influence surface grade because of jaw and the bossing of taking the lead produce to batch.This problem also is a global difficult problem of puzzlement enterprises of producing stainless steel, and the common alleviation way of industry is: one, the form of jaw is transformed; Two, head cushioning corrugated paper when take-up, the degree of utilizing corrugation to alleviate to crease, this method has certain effect for batching alleviating of creasing, but causes the changing of the relative positions of interlayer when batching because of being encased inside of corrugated paper, and being reflected to belt steel surface is exactly the rubbing seal that we are referred to as.So batch and crease and rubbing seal is that a pair of this disappears that is long, because the geneogenous defective that reel causes.
The utility model content
The utility model is in order to overcome weak point of the prior art, to provide a kind of can alleviating to be with the steel generation to batch the line with rubber sleeve of creasing with the rubbing seal.
The utility model is achieved through the following technical solutions:
A kind of can alleviating is with the steel generation to batch the line with rubber sleeve of creasing with the rubbing seal; it is characterized in that; comprise the steel sleeve; described steel sleeve is externally connected to the polyurethane protective sleeve; described polyurethane protective sleeve adopts orange peel to handle; the Roughness Surface on Control that makes the polyurethane protective sleeve is at Ra8-10, and the hardness of described polyurethane protective sleeve is HS=50-55.
The thickness of described polyurethane protective sleeve is 10mm.
The utlity model has following technique effect:
In the line with rubber sleeve of the present utility model; the steel construction of internal layer plays a supportive role; the orange peel processing is done on outer polyurethane protective sleeve surface can guarantee between the first astragal steel and the sleeve enough frictional force is arranged; and; polyurethane protective sleeve hardness is between HS:50-55; both can guarantee to eliminate to batch to crease; can there be enough toughness to avoid rapid wear again; simultaneously; guaranteed certain elasticity by rational hardness; the head of band steel can fall into into colloid surface; reduced batching of belt steel surface and creased, and, in the uncoiling operation, can avoid coil of strip directly to produce the interlayer changing of the relative positions with contacting of mandrel; alleviate the rubbing seal of belt steel surface and batch and crease, improved the surface quality of band steel.
Description of drawings
Fig. 1 produces to batch and creases and the cutaway view of the line with rubber sleeve of rubbing seal for the utility model can alleviate the band steel.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Fig. 1 produces to batch and creases and the cutaway view of the line with rubber sleeve of rubbing seal for the utility model can alleviate the band steel; comprise steel sleeve 2; described steel sleeve 2 is externally connected to polyurethane protective sleeve 1; described polyurethane protective sleeve adopts orange peel to handle; the Roughness Surface on Control that makes the polyurethane protective sleeve is at Ra8-10, and the hardness of described polyurethane protective sleeve is HS=50-55.The thickness of described polyurethane protective sleeve is 10mm.
Before producing rubber-lined cover jacket casing of the present utility model is being batched on the movement uranium; utilize strap rolling-assisting device that steel band is rolled onto on the rubber-lined cover tube; making the band steel be close to the glue face twines; and one enclose and be rolled into coil of strip; because the polyurethane protective sleeve of line with rubber sleeve outside has rational hardness; the head of band steel can fall into into colloid surface; alleviated and taken the lead to press against seal (batch and crease) what the back batched that the band steel causes; described polyurethane protective sleeve has certain elasticity again simultaneously; coil of strip is after the line with rubber sleeve is unloaded in operation production down, and the polyurethane protective sleeve can return to the original form again and reuse.Secondly, when coil of strip (having the line with rubber sleeve) is gone up uncoiling production on the mandrel together with the rubber-lined cover jacket casing when flowing to next process, avoided coil of strip directly to produce the interlayer changing of the relative positions, alleviated the rubbing seal of belt steel surface, improved strip surface quality with contacting of mandrel.
Claims (2)
1. one kind can alleviate the band steel and produces to batch and crease and the line with rubber sleeve of rubbing seal; it is characterized in that; comprise the steel sleeve; described steel sleeve is externally connected to the polyurethane protective sleeve; the surface roughness of described polyurethane protective sleeve is Ra8-10, and the hardness of described polyurethane protective sleeve is HS=50-55.
2. according to claim 1 can alleviating is with the steel generation to batch the line with rubber sleeve of creasing with the rubbing seal, it is characterized in that the thickness of described polyurethane protective sleeve is 10mm.
