Further, the hard layer is attached and clamped on two sides of the elastic layer.

Further, the hard layer is made of Teflon material.

Further, the elastic layer is made of polyurethane.

Furthermore, an adjusting ring is clamped between the backing ring and the bottom of the shearing ring groove.

Further, the adjusting ring is connected with the bottom of the shearing ring groove in an adhering mode.

Has the advantages that: the utility model discloses an anti-clamping and anti-embedding ultrathin stainless steel band high-speed longitudinal shearing device, which comprises a roller body; the surface of the roller body is provided with shearing ring grooves and annular blades in a staggered manner along the axial direction of the roller body; the roller bodies are correspondingly matched in pairs; the shearing ring grooves on different roller bodies are correspondingly embedded with the annular blades; a backing ring is arranged in the shearing ring groove; the backing ring comprises a hard layer and an elastic layer; the backing ring can not only push out the narrow band obtained after shearing by utilizing the resilience performance of the elastic layer to finish discharging, but also reduce the abrasion of the backing ring after long-time use by utilizing the abrasion resistance of the hard layer, thereby ensuring the stable working performance of the backing ring; in addition, the hard layer is specifically attached and clamped on two sides of the elastic layer, so that the elastic part can be protected, the attaching degree of the backing ring and the blade and the bottom of the groove is higher, and the processing effect is better.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in figure 1, the anti-blocking embedded ultra-thin stainless steel band high-speed longitudinal shearing device comprises a roller body 1; the surface of the roller body 1 is provided with shearing ring grooves 11 and annular blades 12 in a staggered manner along the axial direction of the roller body; the roller bodies 1 are correspondingly matched in pairs; different shearing ring grooves 11 on the roller body 1 are correspondingly embedded with annular blades 12; a backing ring 13 is arranged in the shearing ring groove 11; the backing ring 13 includes a hard layer 131 and an elastic layer 132.

Backing ring 13 is through combining together stereoplasm layer 131 and elastic layer 132 to both can utilize elastic layer 132 resilience performance to come to carry out the ejection of compact with the narrowband that obtains after the shearing, can utilize the wear-resisting characteristic of stereoplasm layer 131 to reduce the wearing and tearing of backing ring 13 after long-time the use again, thereby guarantee its stable working property.

The backing ring 13 has a thickness in a natural state smaller than the depth of the shear ring groove 11.

The height difference between the backing ring 13 and the shearing ring groove 11 can be used for adapting to the thickness of the strip and the thickness of the embedded part of the annular blade 12, so that the strip is prevented from being crushed.

The thickness of the backing ring 13 in a natural state accounts for 90-99% of the depth of the shearing ring groove 11.

Because the strip clamping and embedding condition is more likely to occur in the production of the ultrathin stainless steel strip, the natural thickness of the backing ring 13 is not too small, otherwise the stable resilience performance of the backing ring is affected, and if the natural thickness of the backing ring 13 is too small, the blade is easily crushed; preferably, the total thickness of the backing ring 13 is 4.8mm to 4.9mm, and the depth of the shear ring groove 11 is 5mm, leaving a gap of 0.1 mm.

The hard layer 131 is disposed on both sides of the elastic layer 132 in a fitting and clamping manner, and preferably, the thickness of the hard layer 131 on one side is 2mm, and the thickness of the polyurethane is 0.9 mm.

The elastic layer 132 is sandwiched in the middle to exert the elastic performance, and the wear-resistant property of the hard layer 131 ensures the long-term stability of the overall thickness of the backing ring 13, thereby exerting the continuous anti-jamming function.

The hard layer 131 is made of teflon.

The Teflon material has excellent wear resistance, and can meet the structural requirement of the backing ring 13 through bending processing.

The elastic layer 132 is made of polyurethane.

The polyurethane material has large compression amount and large deformation degree, and can ensure that the blades on two sides are attached to the blades and the bottom of the groove is tighter, thereby further improving the shearing effect.

An adjusting ring is clamped between the backing ring 13 and the bottom of the shearing ring groove 11.

When the backing ring 13 needs to be compatible with the processing of a belt material with a slightly larger thickness, an adjusting ring structure can be additionally arranged when the ultra-thin belt material needs to be adapted, so that the effect of reducing the gap is achieved, and the adaptability of the shearing device is favorably improved.

The adjusting ring is connected with the bottom of the shearing ring groove 11 in an adhering mode.

The form of bonding can let the adjustable ring can realize the quick detach to promote the assembly efficiency before the processing.

The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the utility model and these are intended to be within the scope of the utility model.
