Description

Technical Field

[0001] The utility model belongs to the technical field of cold-rolled steel strip coiling, and in particular relates to a jaw-type coiling sleeve suitable for cold-rolled thin steel strips. Background Art

[0002] With the development of modern industry, the demand for cold-rolled thin-gauge steel strip products is increasing. At present, domestic and foreign processing companies generally adopt the direct coiling method of the coiler, and the coiler on the coiler is mostly in the form of a fan-shaped plate. Due to the bulges when the coil expands and contracts, the bulges often cause a large number of creases and scratches in the subsequent coiling process. The thinner the steel strip, the more obvious the creases, resulting in great waste and cost losses.

[0003] Moreover, the tension of the rolling mill is very high during the rolling process. The thinner the material strip, the greater the circumferential force and radial force on the reel during the coiling process. After the reel has been used for a period of time, the fan plate will be deformed. The clearance between some slots and the inclined wedge and the fan plate inside the reel is too small, while the clearance between some slots and the inclined wedge and the fan plate is too large. The supporting force on the plane of the fan plate is unbalanced, resulting in deeper scratches and wear on the fan plate and the pyramid, the expansion and contraction of the reel is hindered, and the failure rate of the reel increases.

[0020] As shown in the accompanying drawings, this embodiment provides a jaw-type winding sleeve suitable for cold-rolled thin strip steel, including a reel 1, with triangular cone-shaped fixed jaws 2 arranged on both sides of the reel 1, and a material trough 3 is opened on the reel 1 corresponding to the fixed jaw 2, and the material strip can be inserted into the fixed jaw 2 by means of the shovel plate provided by the rolling mill.

[0021] A triangular cone-shaped movable jaw body 4 is provided in cooperation with the fixed jaw 2. The movable jaw body 4 is arranged inside the fixed jaw 2. The upper and lower surfaces of the opening of the fixed jaw 2 are both subjected to rounded transition treatment.

[0022] The movable clamp body 4 is provided with a plurality of threaded holes, and the reel 1 is provided with a mounting hole concentrically corresponding to each threaded hole. The movable clamp body 4 is connected to the guide column 5 at the threaded hole, and the guide column 5 extends into the mounting hole respectively and correspondingly.

[0023] A spring 6 is sleeved on each guide post 5 . The length of the spring 6 is greater than that of the guide post 5 . The spring 6 can be compressed freely on the guide post 5 . The guide post 5 can prevent the spring 6 from deviating when it is compressed and deformed.

[0024] A locking column 7 is threadedly connected to the outer end of each spring 6 in the mounting hole. The locking column 7 can compress the spring 6 by pressing the spring 6. The compression amount of the spring 6 can be adjusted by rotating the locking column 7 to adjust the depth of the locking column 7 inserted into the reel 1, thereby controlling the pressure of the dynamic caliper body 4.

[0025] In order to process the installation hole, a groove is opened on the side of the reel 1. In order to avoid indentations in the groove when the material strip is wound on the reel 1, a pressure strip 8 is pressed at the other end of all the locking columns 7. The pressure strip 8 is stuck in the groove set on the side of the reel 1 to make the outer surface of the reel 1 smoother.

[0026] In order to facilitate positioning of the pressure strip 8 during installation, a boss 9 is provided on the pressure strip 8 at each light hole corresponding to the pressure strip 8. The boss 9 extends into the light hole to limit the axial movement of the pressure strip 8.

[0027] When the material is inserted into the bottom of the fixed jaw 2, the movable jaw body 4 is compressed by the force spring 6. Through the relationship between the action force and the reaction force, the force generated by the compression of the spring 6 squeezes the material strip through the movable jaw body 4, and the material groove 3 is shaped as a triangular groove, which increases the friction between the contact surface between the movable jaw body 4 and the fixed jaw 2 and the material strip when clamped. In this way, the head of the strip will not slip out of the fixed jaw 2 during the subsequent winding process, and the strip can be better wound.

[0028] In order to further avoid indentations during the winding process of the material strip on the reel 1, limit plates 10 are hinged at both ends of the pressure strip 8 on the reel 1. After the limit plates 10 are rotated, they can block the ends of the pressure strip 8 and limit the radial movement of the pressure strip 8.

[0029] In order to further fix the pressure strip 8 and the reel 1 and prevent the pressure strip 8 from moving, connecting screw holes are provided on the limit plate 10 corresponding to the ends of the pressure strip 8, and the limit plate 10 and the pressure strip 8 can be fixed by screws 11, thereby fixing the pressure strip 8 and the reel 1.

[0030] It can be understood that the above specific description of the utility model is only used to illustrate the utility model and is not limited to the technical solution described in the implementation mode of the utility model. Ordinary technicians in the field should understand that the utility model can still be modified or replaced by equivalents to achieve the same technical effect; as long as the use requirements are met, they are within the protection scope of the utility model.
