Description

Metal strip coiling device

Technical Field

The utility model belongs to the technical field of the rolling technique of metal band material and specifically relates to a metal band material coiling mechanism is related to.

Background

In the production process of the nonferrous metal strip, the strip needs to be uncoiled and coiled for many times. Before coiling, the head of the strip needs to be wound on a sleeve, then the sleeve is rotated, and the strip is driven to rotate along with the sleeve by virtue of the friction force of the sleeve on the strip, and the process is called coiling. For thicker or stiffer strips, it is difficult to wind either manually or by means of a belt wrapper, the greatest reason being that the strip is not flexible, the bending surface in contact with the sleeve is not large enough, and the strip does not get enough friction to cause slipping. This is a pain point within the current industry, directly affecting the maximum strip thickness, and also the final hot rolled thickness.

SUMMERY OF THE UTILITY MODEL

Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "upper", "lower", "left", "right", "vertical", "horizontal", etc. are based on the directions or positional relationships shown in the drawings, which are only for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

A metal strip coiling device is used for manual operation coiling.

As shown in fig. 1, the sleeve 1 is mounted on a main shaft of a coiling machine, and the main shaft tightly supports the inner sleeve surface of the sleeve 1 through an inner supporting mechanism, so that the sleeve 1 rotates along with the main shaft. The sleeve 1 is made of metal, has good rigidity, and is used for supporting the rolling of a metal strip on the sleeve. The outer cylinder surface of the sleeve 1 is wound with a wrapping belt 2, in order to prevent the wrapping belt 2 from crushing the metal strip, the wrapping belt 2 is made of soft copper or rubber, and the thickness of the wrapping belt 2 is one fourth of the thickness of the metal strip. The head end of the wrapping band 2 is connected with the sleeve 1, and the rest part of the wrapping band 2 is used for wrapping the band head part 3 of the metal strip, so that the metal strip is coiled on the sleeve 1.

As a first connection mode, an axial clamping seam is arranged on the outer cylindrical surface of the sleeve 1, the head end of the wrapping tape 2 is inserted into the clamping seam, and the head end of the wrapping tape 2 is tightly connected with the clamping seam through the jacking screw 4 jacked from the inner cylindrical surface of the sleeve 1, so that the integrity of the outer cylindrical surface of the sleeve 1 can be ensured, and the metal strip can be prevented from being crushed by a threaded hole. In order to realize smooth transition of the bag clamping strap 2 and the outer cylindrical surface of the sleeve 1, the clamping seam has a certain gradient. The smooth transition of the wrapping band 2 on the outer cylindrical surface of the sleeve 1 can reduce the pressure injury of the protruding part on the surface of the metal strip.

As a second connection mode, as shown in fig. 2, an axially through slot is provided on the outer cylindrical surface of the sleeve 1, and the slot has a circular cross section and a closed-end structure. The head end of the wrapping belt 2 is provided with a circular arc-shaped turned edge which is inserted in the clamping groove and connected with the clamping groove. Compared with the first connection mode, the connection mode can prevent the connection part at the head end of the wrapping belt 2 from being broken due to bending fatigue.

As a third connection method, as shown in fig. 3, the connection method is different from the second connection method in that the cross section of the clamping groove is a T-shaped groove, the shape of the head end of the wrapping and clamping band 2 corresponds to the T-shaped groove, the wrapping and clamping band 2 is made of rubber, and the head end of the wrapping and clamping band 2 is formed by injection molding. Due to the adoption of injection molding, compared with the first and second connection modes, seamless smooth transition of the wrapping belt 2 on the outer cylinder surface of the sleeve 1 can be realized. Due to the fact that the rubber material is adopted, the connecting portion of the head end of the wrapping and clamping belt 2 is resistant to bending, and the wrapping and clamping belt 2 can be prevented from pressing the surface of the metal strip more comprehensively.

In the winding process, as shown in fig. 1, a sleeve 1 and a wrapping tape 2 are firstly installed on a main shaft of a winding machine according to the winding direction, then a tape head 3 of the metal strip is clamped between the sleeve 1 and the wrapping tape 2, the winding machine is started to slowly rotate the sleeve 1, at this time, the tail end of the wrapping tape 2 is pulled down by hands, and the wrapping tape 2 wraps the tape head 3 of the metal strip. Under the action of a lower pulling force, the head 3 of the metal strip generates bending deformation, the inner side surface of the metal strip is attached to the sleeve 1 to generate friction force, the outer side surface of the metal strip is attached to the wrapping and clamping belt 2 to generate friction force, the metal strip rotates along with the sleeve 1 under the action of the friction force and is pulled to generate tension, and the rolling of the thicker metal strip on the sleeve 1 is realized. As can be seen from fig. 1, the wrapping and clamping belt 2 wraps the belt head of the metal strip, so that the belt body is prevented from being crushed by the belt head.

The material of the strap 2 may be various, and may be metallic or non-metallic, such as rubber. When the package is taken 2 and is adopted rubber materials, rubber materials can prevent the area body crushing better on the one hand, and the coefficient of friction of on the other hand rubber and metal will be more than the coefficient of friction between metal and the metal, consequently can obtain bigger frictional force, and the quick roll-up reduces and slides, skids the damage that causes the metal strip surface. The disadvantage of using rubber for the strap 2 is that the tensile strength of the rubber band is low and cannot be made as thin as a metal band. The strap 2 can thus also combine the advantages of a metal strap and a rubber strap, namely that a rubber layer 22 is sprayed or glued on both sides of the metal base strap 21. As shown in fig. 4, the metal base band 21 may be provided with a plurality of rows of meshes, and the rubber layers 22 on both sides of the metal base band 21 may be connected together through the meshes, thereby improving the connection strength between the rubber layers 22 and the metal base band 21 and preventing the rubber layers 22 from falling off. After the measures are taken, the wrapping band 2 has good tensile strength, larger friction coefficient and elastic protection capability to the metal strip. In addition, the wrapping and clamping belt 2 can be added with netted warps and wefts in the rubber belt like a transmission belt, so that the wall thickness can be reduced, and the tensile strength of the rubber belt is improved.

The length of the bag clamp belt 2 is not suitable to be too long, and the overlong bag clamp belt 2 loses the function after being rolled. The bag clamp belt 2 is not too short, and the too short bag clamp belt cannot play a good rolling role and also brings danger to operators. In general, the length of the entrainment band 2 is preferably 1 to 3 times the circumference of the barrel surface of the sleeve 1.
