Detailed ways

The implementation of the present utility model will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

Without loss of generality, this embodiment is described by taking the retaining of the inner ring of the metal strip coil as an example. It should be understood that the supporting device of the present application can be applied to any occasion of retaining the inner ring of the coil or repairing defects. Secondly, in the description of the present utility model, it should be noted that the orientations or positional relationships indicated by the terms "center", "middle", "inner", "outer" etc. are based on the orientations or positional relationships shown in the drawings, It is only for the convenience of describing the present invention and simplifying the description, but does not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and should not be understood as indicating or implying relative importance.

A supporting device for a metal coil provided in this embodiment includes two oppositely arranged central hinge blocks 1 and a threaded pull rod 6; the threaded pull rod 6 passes through the central holes on the two central hinge blocks 1, At least one central hinge block 1 can be moved and fixed along its axial direction on the threaded pull rod 6, and a plurality of support bars 2 equal in number are hinged on each central hinge block 1, and the two center hinge blocks The hinged support bars 2 on 1 correspond to each other and are connected by hinged joints 4 .

Referring to Fig. 1, there are four hinged joints 4 in the support device, and eight support bars 2. The support bars 2 are evenly distributed around the two central hinge blocks 1, and the support bars hinged on the two center hinge blocks correspond to each other, and the support bars are connected by hinge joints 4 between the two, so that connected into an approximate octahedral framework. Wherein all hinge relationships are realized by using the pin 3 . Of course, hinges or other structures other than this can also achieve hinged fixation. There is no limit structure at both ends of the threaded pull rod 6. After the central hinge block 1 is sleeved on the threaded pull rod 6, the central hinge block 1 can move axially on the threaded pull rod. At this time, the two nuts are screwed to on the threaded pull rod 6, and are respectively fixed on the outsides of the two central hinged blocks 1. At this time, a thread fit is formed between the nut and the threaded pull rod 6 , and the resistance center hinge block 1 moves axially on the threaded pull rod 6 . When the inner circle of the metal strip coil 8 collapses, first at least one nut is rotated towards the end of one end of the threaded tie rod 6 where it is located, so that the distance between the two central hinge blocks 1 tends to increase, and at this time the support The device shrinks gradually until it can be smoothly put into the metal strip coil 8 where the inner ring collapses, and then the shrinkage can be stopped. After being placed in the metal strip coil 8, in order to repair the collapse of the inner ring, it is necessary to make the distance between the two central hinge blocks 1 tend to decrease at this time, so at least one nut is rotated in a direction away from the end where it is located, so that Drive the support bar 2 and the hinged joint 4 to expand around and withstand the inner ring of the metal strip coil 8 until the repair of the metal strip coil 8 is completed.

It is worth mentioning that when the hinged joint 4 is in direct contact with the inner ring of the metal strip coil 8 , due to the high pressure, the inner ring of the metal strip coil 8 may be crushed. In view of this, in this embodiment, a buffer block 5 is provided on the outside of the hinge joint 4 , wherein the outside refers to the side away from the central hinge block 1 . The material of the buffer block 5 is preferably but not limited to polyurethane elastomer.

In addition, threaded holes are also provided at the corresponding positions of the two central hinge blocks 1 in the supporting device of this embodiment. When the two central hinge blocks 1 are close on the threaded pull rod 6, the bolt 7 is used to pass through the threaded hole and tightened with nuts so that the two center blocks are fixed at the nearest position. At this time, the threaded pull rod 6 is moved from Pull out in the support device, the support device can still maintain the support to the metal strip coil 8 inner ring. The supporting device after the threaded pull rod 6 is removed is more convenient for the transportation, storage or subsequent application of the metal strip coil 8 .

In addition to the structure of the threaded tie rod 6 described in this embodiment, one end of the threaded tie rod 6 can also be provided with a limiting structure, and the other end can pass through the center holes of the two central hinge blocks in sequence and then be connected with the nut. By rotating the nut so that it moves on the threaded pull rod 6, the central hinge block on one side of the nut is fixed on the inner side of the nut.

It should be noted that the support device provided in this embodiment can be used in the manufacturing process of the metal strip coil 8 in addition to being applied to the repair of the collapse of the inner ring, so as to avoid deformation or loosening of the metal strip coil 8 during the manufacturing process. In addition, the number of support bars and hinged joints is not limited to the number listed in the embodiment.

The above embodiments are only used to illustrate the utility model, but not to limit the utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present utility model will not depart from the spirit and scope of the technical solutions of the present utility model.
