All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Thin metal strip in cold rolling plants needs to be wound to an elastic sleeve to facilitate storage and transportation of the strip. The coiled strip steel is generally defective in the belt mark, and the belt with the belt mark influences the use of the strip steel with the belt mark to cause waste of the belt steel with the belt mark. In order to reduce the waste of coiling the strip steel, the length of the strip steel with the head mark needs to be controlled within a certain meter. Because the position of the belt head protrudes out of the outer side wall of the elastic sleeve in the process of coiling the strip steel, the belt head mark is difficult to eliminate
In order to solve the technical problem that the belt mark on the coiled strip steel in the related art is difficult to eliminate, the application provides a coiling machine and a coiling method. A first aspect of the present application provides a coiler, referring to fig. 1, comprising a mandrel 10 and an elastic sleeve 20.
The mandrel 10 is rotatably mounted on a frame (not shown), and the elastic sleeve 20 is sleeved outside the mandrel 10. In order to facilitate the sleeve 20 to be sleeved on the mandrel 10, a telescopic rib (not shown) may be provided on the circumferential side of the mandrel 10, and the telescopic rib may be telescopic along the radial direction of the mandrel 10. When the elastic sleeve 20 is required to be sleeved on the peripheral side of the mandrel 10, the telescopic ribs shrink, the elastic sleeve 20 is sleeved on the peripheral side of the mandrel 10, and then the telescopic ribs relax to support the elastic sleeve 20 to reel the strip steel. When it is necessary to remove the elastic sleeve 20 from the circumferential side of the mandrel 10, the telescopic ribs contract, removing the elastic sleeve 20 from the circumferential side of the mandrel 10.
The elastic sleeve 20 is used for coiling the strip steel 30, and the elastic sleeve 20 is sleeved outside the mandrel 10. The elastic sleeve 20 is provided with an inner cavity 21 extending along the axial direction and a first opening 211 communicated with the inner cavity, and the first opening 211 is used for inputting and outputting gas in the inner cavity 21. When the elastic sleeve 20 winds the thin metal strip 30, the head 31 of the strip 30 can be threaded to the peripheral side wall of the elastic sleeve 20 and to a position corresponding to the inner cavity 21 using a winding aid. Because the elastic sleeve 20 has elasticity, when the strip steel 30 is wound on the elastic sleeve 20, the strip head 31 receives the pressure of the outer strip steel 30 and transmits the pressure to the elastic sleeve 20, the corresponding position of the elastic sleeve 20 and the strip head 31 of the strip steel 30 deforms and moves towards the inner part of the inner cavity 21, the corresponding position of the outer side wall of the elastic sleeve 20 and the strip head 31 is sunken towards the inner cavity 21, the strip head 31 can be clamped in the sunken space, thus the local stress of the strip head 31 of the strip steel 30 on the strip steel 30 can be reduced, the strip head mark is prevented from being generated due to the fact that the strip head 31 is pressed against the trace at the corresponding position of the strip head 31 by the outer strip steel 30, the waste of the strip steel 30 is further reduced, and the use rate of the strip steel 30 is improved.
The elastic sleeve 20 may be a rubber sleeve, and the hardness of the rubber sleeve is 65Shore a to 90Shore a, so that the elastic sleeve 20 has elasticity and a certain supporting force, and the practicability of the elastic sleeve 20 is improved. The material of the elastic sleeve 20 may be butyl rubber, natural rubber, etc., and may be set according to actual requirements, which is not limited in this application.
In order to deform the elastic sleeve 20 when the band head 31 is pressed by the outer band steel 30, the inner cavity 21 is close to the outer ring of the elastic sleeve 20 relative to the inner ring of the elastic sleeve 20, so that the distance between the inner side wall of the inner cavity 21 and the outer ring of the elastic sleeve 20 can be reduced, and the inner cavity 21 is close to the outer ring of the elastic sleeve 20 and the elastic sleeve 20 has elasticity. When the outer side wall of the elastic sleeve 20 is pressed at the corresponding position of the belt head 31, the outer side wall of the elastic sleeve 20 and the corresponding position of the belt head 31 can be deformed in time, so that along with the rapid rotation of the elastic sleeve 20, the outer side wall of the elastic sleeve 20 and the corresponding position of the belt head 31 can be deformed in time, and the belt head 31 with the belt head mark on the outer layer strip steel 30 is prevented.
In order to make the deformation uniformity of the inner cavity 21 along the axis, the elastic sleeve 20 is provided with a second opening 212 communicated with the inner cavity 21, the first opening 211 and the second opening 212 are respectively located at two end faces of the elastic sleeve 20 along the axial direction, so that the inner cavity 21 can be communicated with the outside through the first opening 211 and the second opening 212, and when the outer side wall of the elastic sleeve 20 is pressed, the corresponding position of the outer side wall of the elastic sleeve 20 and the belt head 31 can be deformed in time.
Referring to fig. 2 to 4, the cross section of the inner cavity 21 along the axis perpendicular to the axis may be rectangular, and the long side of the rectangle is close to the outer sidewall of the elastic sleeve 20, so as to enlarge the corresponding area of the inner cavity 21 on the outer sidewall of the elastic sleeve 20, so that the tape head 31 is conveniently threaded to the peripheral sidewall of the elastic sleeve 20 and corresponds to the inner cavity 21.
Because the edge of the inner cavity 21 has larger supporting strength under the supporting of the inner side wall, the outer layer strip steel 30 can be directly abutted on the edge of the inner cavity 21, so that the position of the strip steel 30 corresponding to the edge of the inner cavity 21 can be stamped, and the use of the strip steel 30 is affected to cause the waste of the strip steel 30.
In some embodiments, in order to prevent the stamping from being generated at the position corresponding to the edge of the inner cavity 21 on the strip steel 30, the inner cavity 21 may also be crescent-shaped along the section perpendicular to the axis, and the crescent-shaped inner cavity 21 is bent towards the axis position of the elastic sleeve 20, so that the arc transition can be realized at the position corresponding to the outer side wall of the crescent-shaped inner cavity 21 and the outer side wall of the elastic sleeve 20, the edge of the inner cavity 21 is prevented from corresponding to the outer side wall of the elastic sleeve 20, the stamping generated at the position corresponding to the edge of the inner cavity 21 on the strip steel 30 is further reduced, and the utilization rate of the strip steel 30 is improved. In some embodiments, the cross section of the inner cavity 21 along the axis perpendicular to the axis may also be diamond, oval, circular, etc., and may be set according to practical situations, which is not limited in this application.
In order to facilitate the installation of the elastic sleeve 20 on the mandrel 10, the inner ring of the elastic sleeve 20 is provided with a 45-degree chamfer of 2mm to 5mm, and the chamfer can play a guiding role, so that the elastic sleeve 20 can be conveniently and smoothly sleeved on the periphery of the mandrel 10 under the guiding role of the chamfer, and the convenience of the elastic sleeve 20 in installation of the mandrel 10 is improved.
A second aspect of the present application provides a winding method, referring to fig. 5, the winding method is applied to the winding machine. The coiling method comprises the following steps:
102. an elastic sleeve 20 is mounted to the mandrel 10.
104. The band head 31 of the band steel 30 is threaded to the outer side wall of the elastic sleeve 20 and corresponds to the position of the inner cavity 21.
The elastic sleeve 20 for coiling the strip steel 30 is sleeved on the mandrel 10 of the coiling machine, in order to facilitate coiling the strip steel 30 to the elastic sleeve 20, the mandrel 10 is rotated to enable the inner cavity 21 to be located above, so that the strip head 31 of the strip steel 30 can be conveniently conveyed to a position above the elastic sleeve 20 corresponding to the inner cavity 21, and the strip head 31 of the strip steel 30 is penetrated to the outer side wall of the elastic sleeve 20 and corresponds to the inner cavity 21. The belt winding aid hugs the metal strip 30, the winding machine starts to rotate, and the winding process starts.
106. The mandrel 10 is rotated to apply a set tension to the strip 30 to wind the strip 30 out of the elastomeric sleeve 20.
As the mandrel 10 rotates, the mandrel 10 may drive the elastic sleeve 20 to rotate. To tighten the strip 30 around the elastic sleeve 20, the mandrel 10 is rotated to apply a set tension to the strip 30 to wind the strip 30 out of the elastic sleeve 20.
In some embodiments, rotating the mandrel 10 to apply a set tension to the strip 30 to cause the strip 30 to be coiled out of the elastomeric sleeve 20 includes: the mandrel 10 is rotated to sequentially apply a first tension, a second tension, and a third tension to the strip steel 30, so that the strip steel 30 is wound around the elastic sleeve 20.
Wherein the first tension is less than the third tension and the second tension is greater than the third tension.
The third tension is the tension at which the mandrel 10 normally winds the strip 30. When the elastic sleeve 20 begins to wind the strip steel 30, the mandrel 10 uses a first tension, which is less than the third tension, and the first tension may be 0.6 to 1.0 times the third tension. The strip steel 30 can be coiled under small tension of the mandrel 10, so that the coiled strip steel 30 at the outer layer is soft, the pressure of the strip head 31 of the strip steel 30 at the outer layer is reduced, the local stress of the strip head 31 of the strip steel 30 on the outer layer strip steel 30 can be reduced, the generation of the strip head marks at the positions corresponding to the strip head 31 of the outer layer strip steel 30 is prevented, the waste of the strip steel 30 can be reduced, and the utilization rate of the strip steel 30 is improved.
In the coiling process of the strip steel 30, the head of the metal strip steel 30 is coiled by using small tension, then the inner cavity 21 is formed in the axial direction of the cylinder body of the rubber elastic sleeve 20, the strip head 31 of the thin metal strip steel 30 is penetrated into the outer side wall of the rubber elastic sleeve 20 and corresponds to the inner cavity 21 to start coiling, the local stress of the strip head 31 of the thin metal strip steel 30 on the outer strip steel is reduced, and the defect of strip head printing in the coiling process is avoided.
The mandrel 10 may wind the strip 30 using a first tension between about 6 meters and about 12 meters and wind the strip 30 using a second tension that is greater than the third tension, which may be between about 1.1 and about 1.3 times the third tension. When the strip steel 30 of 6 to 12 m is wound on the elastic sleeve 20, the influence of the strip head 31 of the strip steel 30 on the outer strip steel 30 is reduced. The second tension is used for coiling the strip steel 30, and the second tension can be 1.1 to 1.3 times of the third tension, so that the strip steel 30 can be tightly coiled on the elastic sleeve 20, the compactness and stability of the strip steel 30 coil are improved, and the collapse of the strip steel 30 coil is prevented.
The first tension may be m times the third tension, and the second tension may be n times the third tension, where m is less than 1, n is greater than 1 and less than 2. The first tension and the second tension can be set according to actual requirements, and the application is not limited.
The mandrel 10 may use the second tension to wind the strip 30 to 200 meters to 400 meters and then return to the third tension in the form of a ramp slope, using the third tension to wind the strip 30. When the mandrel 10 is used to wind the strip 30 to 200 meters to 400 meters with the second tension, the compactness and stability of the strip 30 roll are improved. The strip steel 30 is coiled with a third tension until the strip steel 30 coiled on the elastic sleeve 20 reaches a preset coil weight, and the strip steel 30 coil is uncoiled and ready for the next coiling. The number of defective meters of the strip head mark can be reduced, the quality of the strip steel 30 is improved, and the yield and the production efficiency of the strip steel 30 are improved.
Because the elastic sleeve 20 has elasticity, when the strip steel 30 is wound on the elastic sleeve 20, the strip head 31 receives the pressure of the outer strip steel 30 and transmits the pressure to the elastic sleeve 20, the position of the elastic sleeve 20 corresponding to the strip head 31 of the strip steel 30 deforms and moves towards the inner part of the inner cavity 21, the position of the outer side wall of the elastic sleeve 20 corresponding to the strip head 31 is concave towards the inner cavity 21, and the strip head 31 can be clamped in the concave space, so that the local stress of the strip head 31 of the strip steel 30 on the strip steel 30 can be reduced, the generation of the strip head mark at the position of the outer strip steel 30 corresponding to the strip head 31 can be prevented, the waste of the strip steel 30 can be further reduced, and the use rate of the strip steel 30 can be improved.
