The specific meaning of the above terms in the creation of the present utility model can be understood by those of ordinary skill in the art in a specific case.

It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element.

As shown in fig. 1 to 4, the anti-offset clamp for coiled material rolling disclosed by the utility model comprises a first flange 1, a second flange 2 and a locking piece 3, wherein the first flange 1 is provided with a first clamping section 12 and a first limiting section 11 which are arranged on a first plane and fixedly connected with each other; the second flange 2 has a second clamping section 22 corresponding to the first clamping section 12; the locking piece 3 is used for fixing the distance between the first flange 1 and the second flange 2; at least one opposite end of the first flange 1 and the second flange 2 is an open end 10, and the locking piece 2 is at least arranged at the open end 10; the first clamping section 12 and the second clamping section 22 each have opposing non-slip clamping surfaces 100.

The first plane is a plane in any direction, and the first clamping section 12 and the first limiting section 11 are arranged on the first plane, i.e. are coplanar.

Because the roller is cylindrical, in order to increase the contact area between the first flange 1 and the second flange 2 and the roller surface, and further improve the stability, the anti-slip clamping surface 100 is a cambered surface extending along the direction perpendicular to the first plane. The non-slip gripping surface 100 is provided with protrusions and/or a non-slip layer protruding from the non-slip gripping surface 100. Wherein the anti-slip layer is made of materials such as rubber which are deformed by extrusion; the anti-slip layer is a coating with coarse particles. The protrusions may be uniformly distributed on the anti-slip grip surface or may be irregularly distributed on the anti-slip grip surface, such as corrugated protrusions.

As shown in fig. 1, the locking member 3 may be an elastic rope, the first flange 1 and the second flange 2 are provided with L-shaped bending parts, one end of each bending part is a connecting end, and the extending direction of the other end is parallel to the first limiting section 11; the retaining member 3 can be the combination of bolt and nut, and first flange 1 and second flange 2 all are provided with the locating hole, and the bolt wears to locate in the locating hole, and the end that stretches out of bolt cooperates with nut screw thread, adjusts the interval of first flange 1 and second flange 2 through the distance of nut spiral, and then adjusts the elasticity of centre gripping between first flange 1 and the second flange 2.

In order to further improve the limiting effect, two ends of the first clamping section 12 are connected with coplanar first limiting sections 11. That is, the first limiting sections 11 are respectively arranged at two ends of the first clamping section 12, the first limiting sections 11 at the two ends extend and intersect, the intersecting angle is any included angle, and the included angle can be one of acute angle setting, right angle setting, obtuse angle setting and flat angle setting. Due to the first limiting section 11 arranged at the included angle, the force and the force distribution of limiting and resisting are further increased, and the coil rolling stability is better.

Because the clamp is directly clamped with the roller, although the clamp rotates along with the roller, the relative positions of the clamp, the roller and the coiled material curled edge are kept unchanged, the coiled material curled edge is in instant contact with the first flange and/or the second flange, friction is generated for a short time, and static electricity is not easy to generate. Compared with the prior limit mechanism, the installation position is fixed relative to the machine base, friction force is easy to generate along with the rotation of coiled materials and the relative sliding of the limit mechanism, the brought static is easy to absorb dust, and the static eliminating piece is required to be arranged and is matched with the limit mechanism together to achieve the effect of stable winding.

In order to ensure that the first flanges exert symmetry against the reaction force and use stability, the extension directions between the first limiting sections 11 are consistent. I.e. the included angles at which the first limiting sections 11 at the two ends extend and intersect are arranged in a flat angle.

In order to further improve the limiting effect and the use stability of the clamp, the two ends of the second clamping section 22 are provided with second limiting sections 21 which are in groups with the first limiting sections 11 and are parallel to each other. The first limit section 11 and the second limit section 21 are provided with a fixedly connected resisting surface, although the contact surface between the first flange 1 and the second flange 2 and the end part of the coiled material is enlarged, and the limit effect is improved. But is unfavorable for the flexible installation of the first flange 1 and the second flange 2 at the end of the roller, and is unfavorable for the adjustment of the distance between the first flange 1 and the second flange 2, and further for the adjustment of the sizes of the clamping forces and the rollers with different diameters. Further, the first limiting section 11 and the second limiting section 21 are disposed at intervals, that is, the first limiting section 11 and the second limiting section 21 may be disposed separately or may be disposed in a bifurcated manner.

Further, the outer Zhou Jun of the first limiting section 11 and the second limiting section 21 are sleeved with limiting rollers 13; or the first limiting section 11 and the second limiting section 21 are both provided with convex abutting cambered surfaces, and the extending direction of the abutting cambered surfaces is consistent with that of the first limiting section 11. The first limiting section 11 and the second limiting section 21 are of any geometric body, the limiting roller 13 is a hollow cylinder, the first limiting section 11 and the second limiting section 21 are sleeved, friction surfaces are reduced when the first limiting section 11 and the second limiting section 21 are in crimping butt joint with coiled materials, and abrasion of the first limiting section 11 and the second limiting section 21 to coiled materials is further reduced. The first limiting section 11 and the second limiting section 21 are arbitrary geometric bodies, but are provided with convex abutting cambered surfaces, so that friction surfaces of the first limiting section 11 and the second limiting section 21 and coiled material curled edges can be reduced, and abrasion of the first limiting section 11 and the second limiting section 21 to the coiled material curled edges is further reduced. In order to simplify the structure and processing of the first limiting section 11 and the second limiting section 21, further, the first limiting section 11 and the second limiting section 21 are both cylinders. Further, the first limiting section 11 and the second limiting section 21 are made of stainless steel.

As shown in fig. 1, in an embodiment, opposite ends of the first flange 1 and the second flange 2 are open ends 10, so that the open ends 10 are provided with locking members 3, and a protruding structure formed by combining a bending portion or a bolt and a nut faces one side of the first plane, and the other side faces the coiled material for curling, so that the operation is convenient and the coiled material is not damaged.

In another embodiment, as shown in fig. 2, a group of ends opposite to the first limiting section 11 and the second limiting section 21 are fixed ends 20, and the fixed ends 20 are in arc transition connection; the other group of ends opposite to the first limiting section 11 and the second limiting section 21 are open ends 10, and the open ends 10 are provided with locking pieces 3. I.e. the opposite ends of the first flange 1 and the second flange 2 are open ends 10. In order to increase the clamping force created by the pinching of the open end 10, the spacing of the open end 10 from the center of the first clamping section 12 is less than or equal to the spacing of the fixed end 20 from the center of the first clamping section 12. The principle is that the moment arm is small and the moment at the other end can be balanced by increasing the force. In order to prevent the fixed end 20 from wearing the rolled edge of the coiled material, the fixed end 20 is offset towards one side of the bending part, and the fixed end 20 and the first plane form an acute included angle.

As shown in fig. 3, in a preferred embodiment, a group of ends opposite to the first limiting section 11 and the second limiting section 21 are fixed ends 20, and the fixed ends 20 are in arc transition connection; the other group of ends opposite to the first limiting section 11 and the second limiting section 21 are open ends 10, and the fixed ends 20 and the open ends 10 are provided with locking pieces 3.

In another preferred embodiment, as shown in fig. 4, in order to increase the clamping force and provide anti-slip property, after simplifying the structure, the first clamping section 12 and the second clamping section 22 are arranged in parallel by at least two arc-shaped steel bodies, and the arrangement direction of the steel bodies is perpendicular to the first plane. For keeping flatness and stability of the resisting surface of the clamp, and for simplifying the structure and improving the application universality, the first flange 1 and the second flange 2 are integrally connected, the first limiting section 11 and the second limiting section 21 are also formed by at least two arc-shaped steel bodies in parallel, the arrangement direction of the steel bodies is vertical to the first plane, namely, the clamp is formed by arranging and fixedly connecting at least two stainless steel pipes in parallel, and the arrangement direction of the pipes is vertical to the first plane. The pipe bodies are fixedly connected in a welding mode.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several modifications and variations can be made without departing from the technical principle of the present utility model, and these modifications and variations should also be regarded as the scope of the utility model.
