Description

Technical field:

[0002] The utility model relates to a tool for rotating the flat head direction of a working roller. Background technology:

[0004] After working for a period of time, the cold rolling mill needs to remove the working rolls for grinding, and then reinstall the working rolls. Then, a flat square sleeve is installed on the flat head at the end of the working roll so that it can be connected to the transmission shaft through a coupling. However, when the working rolls are reinstalled into the cold rolling mill, the position of the flat head at the end of the working roll is prone to not correspond to the position of the flat square sleeve, and the position needs to be adjusted at this time. There are currently two measures for adjusting the position of the flat head and adjusting the position of the flat square sleeve. Due to the large shape of the flat square sleeve, it is usually necessary to use lifting equipment for adjustment. During operation, the staff needs to repeatedly check the position of the flat head and adjust the flat head many times, which is inconvenient to operate; and when adjusting the position of the flat head, due to the narrow position, the staff cannot use force to turn the flat head by hand, resulting in considerable difficulties in adjusting the position of the flat head. For this reason, if a tool can be designed to facilitate the staff to manually turn the direction of the working flat head, it will improve the convenience of operation, and this case is born. Utility model content:

[0020] Figure 6 It is a schematic diagram of the main structure of the third embodiment of the present utility model. Specific implementation method:

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] Embodiment 1: Figures 1-2As shown, the utility model is a tool for rotating the direction of the flat head of a working roll, comprising an operating rod 1, an operating head 2 is fixed at one end of the operating rod 1, and a U-shaped operating port 4 for inserting and sleeved on the outside of the working flat head 3 is provided on the operating head 2, the width of the operating port 4 matches the width of the working flat head 3, and the opening of the operating port 4 is located at the end of the operating head 2 away from the operating rod 1. During operation, the U-shaped operating port 4 is inserted and sleeved on the outside of the working roll flat head 3, and the two side walls of the operating port 4 are in contact with the two side planes of the working roll flat head. Then, the operating head 2 is rotated by the operating rod 1, and the operating head drives the working roll flat head to rotate, so as to realize the rotation of the direction of the working roll flat head. The U-shaped operating head and the operating rod form a structure similar to a wrench, which is convenient for the staff to rotate the direction of the flat head at the end of the working roll, and the operation is simple and convenient.

[0025] In this embodiment, the side wall of the operating port 4 is provided with an anti-skid coating to prevent the operating head and the working flat head from slipping during use, thereby affecting normal operation.

[0026] In this embodiment, the operating head and the operating rod are both made of metal. Further, the operating head and the operating rod are welded and fixed.

[0027] Embodiment 2: Figures 2 to 4 As shown, the difference between this embodiment and the first embodiment is that the operating rod 1 is composed of a plurality of rod sections 5 coaxially spliced ​​together, so that the length of the operating rod can be adjusted as needed during use.

[0028] Specifically, a connecting protrusion A6 is coaxially provided at one end of the rod body 5, and a connecting hole A7 for matching with the connecting protrusion A6 is coaxially provided at the other end of the rod body 5. The outer peripheral side of the connecting protrusion A6 is provided with an external thread A, and the inner peripheral side of the connecting hole A7 is provided with an internal thread A for matching with the external thread A. When two sections of the rod body are spliced, the connecting protrusion A of one section of the rod body is screwed into the connecting hole A of the other section of the rod body, and the splicing is achieved by threaded connection, which is convenient for assembly and disassembly. It should be noted that the number of rod bodies can be increased or decreased according to needs during use.

[0029] Embodiment 3: Figures 5-6 As shown, the difference between this embodiment and the second embodiment is that it also includes a connecting elbow 8, which is a 90-degree elbow. The connecting elbow 8 is used to connect between the two sections of the rod body 5 to change the shape of the operating rod to adapt to operations in narrow positions. For example, when the operating rod is in a straight line, if the operating space is relatively narrow, it is inconvenient for the staff to hold the operating rod and operate it. By changing the operating rod into an L shape through the connecting elbow, the problem of inconvenience in operation caused by narrow space can be overcome to a certain extent.

[0030] Specifically, one end of the connecting elbow 8 is provided with a connecting protrusion B9 for matching with the connecting hole A7, and the outer peripheral side surface of the connecting protrusion B9 is provided with an external thread B for matching with the internal thread A; the other end of the connecting elbow 8 is provided with a connecting hole B10 for matching with the connecting protrusion A6, and the inner peripheral side surface of the connecting hole B10 is provided with an internal thread B for matching with the external thread A. That is, the connecting elbow is also matched with the rod body in a threaded connection manner, which is convenient for assembly and disassembly.

[0031] It should be noted that the connecting elbow can also be at other angles, such as 30 degrees, 60 degrees, etc., which can be selected according to needs.

[0032] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0033] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0034] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
