Description

Technical Field

[0001] The utility model belongs to the technical field of graphite steel working rolls for a two-roller stand of a plate and strip, and more specifically, particularly relates to an improved graphite steel working roll for a two-roller stand of a plate and strip. Background Art

[0002] The two-roller stand for plate and strip is a device used for rolling metal plates or strips, in which the working rolls are made of graphite steel. Graphite steel is a special steel with excellent wear resistance, high temperature resistance and thermal conductivity. It is suitable for manufacturing working rolls that need to withstand high temperature, high pressure and high load. The graphite steel working rolls for the two-roller stand for plate and strip play a vital role in the rolling process of metal plates or strips. They not only affect the processing efficiency and product quality, but also directly relate to the stable operation of the equipment and production costs.

[0003] At present, the graphite steel working rolls used in some two-roller stands for plate and strip are usually made in one piece. However, during the use of the graphite steel working rolls, the surface of the working rolls is easily damaged. Therefore, when the surface of the working rolls is damaged, the rolls can only be replaced as a whole, which greatly increases the production cost.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an improved graphite steel working roll for a two-roller stand for plate and strip is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0009] Furthermore, the number of the connecting blocks 1 is equal to the number of the connecting grooves 1, and the sizes of the connecting blocks 1 match those of the connecting grooves 1.

[0010] Furthermore, both sides of one end of the card block are beveled surfaces, the number of the card blocks is equal to the number of the card slots, and the sizes of the card blocks and the card slots match.

[0011] Furthermore, the size of the connecting block 2 matches that of the connecting groove 2.

[0012] Furthermore, a pair of mounting heads are mounted on both ends of the roller body.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] Through the coordinated use of connecting block 2, connecting groove 2, rotating block, screw rod, push block, clamping block and clamping groove, when the surface of the roller sleeve is damaged and needs to be replaced, a new roller sleeve is put on the outside of the roller body, and then the connecting block 2 is moved into the connecting groove 2, so that the baffle limits the roller body, and then the rotating block is rotated with the help of a tool, and the rotating block drives the screw rod to rotate. Since the screw rod is threadedly connected to the thread groove, the push block is driven forward when the screw rod rotates. When the push block is pushed forward, one end of a pair of clamping blocks with beveled surfaces can be pushed out of the movable groove respectively, and inserted into the clamping groove to fix the roller sleeve, thereby achieving the effect of quickly and conveniently replacing the roller sleeve, thereby reducing the replacement cost of the working roller.

[0027] Example:

[0028] As attached Figure 1 To Attachment Figure 7 As shown:

[0029] The utility model provides an improved graphite steel working roll for a two-roller frame of a plate and strip, comprising a roll body 1 and a roll sleeve 2, a plurality of connecting blocks 3 are installed on the periphery of the roll body 1, a slide groove 4 is provided at one end of the connecting block 3, a push block 5 is slidably connected in the slide groove 4, a threaded groove 501 is provided at one end of the push block 5, a screw rod 6 is threadedly connected in the threaded groove 501, movable grooves 7 are provided on both sides of the slide groove 4, a clamping block 8 is movably connected in the movable groove 7, a connecting block 9 is installed on the periphery of one end of the roll body 1, and the roll sleeve 2 is provided on the periphery of the roll body 1. The inner wall of the sleeve 2 is provided with a plurality of connecting grooves 10, and a pair of clamping grooves 11 are provided on both sides of the connecting groove 10. A baffle 12 is installed at one end of the roller sleeve 2, and a connecting groove 13 is provided on the surface of the baffle 12. The connecting block 9 moves into the connecting groove 13, so that the baffle 12 can limit the roller body 1. Since the screw rod 6 is threadedly connected with the thread groove 501, the screw rod 6 drives the push block 5 to move forward when it rotates. When the push block 5 is pushed forward, a pair of clamping blocks 8 can be pushed out from the movable groove 7 respectively.

[0030] One end of the screw rod 6 passes through one side of the slide slot 4 and is provided with a rotating block 601 . The rotating block 601 is rotated by a tool, and the rotating block 601 drives the screw rod 6 to rotate.

[0031] Among them, both sides of the end of the push block 5 away from the thread groove 501 are beveled surfaces. Since both sides of one end of the push block 5 are beveled surfaces, when the push block 5 is pushed forward, it is convenient to push the ends of a pair of clamping blocks 8 with beveled surfaces out of the movable groove 7 respectively.

[0032] The number of the connecting blocks 3 is equal to the number of the connecting grooves 10 , and the sizes of the connecting blocks 3 and the connecting grooves 10 match, and the roller body 1 is connected to the roller sleeve 2 through the connecting blocks 3 .

[0033] Among them, the two sides of one end of the block 8 are beveled surfaces, the number of blocks 8 is equal to that of the slots 11, and the sizes of the blocks 8 and the slots 11 match. The beveled surfaces on both sides of one end of the block 8 can reduce resistance, making it convenient to push the block 8 into the movable slot 7 when disassembling the roller sleeve 2.

[0034] The size of the second connection block 9 matches that of the second connection groove 13 .

[0035] A pair of mounting heads 14 are installed at both ends of the roller body 1, and the mounting heads 14 facilitate the installation of the working roller.

[0036] The working principle of this embodiment:

[0037] By using the connecting block 29, the connecting groove 213, the rotating block 601, the screw rod 6, the pushing block 5, the clamping block 8 and the clamping groove 11 in coordination, when the surface of the roller sleeve 2 is damaged and needs to be replaced, the new roller sleeve 2 is sleeved on the outside of the roller body 1, and the connecting block 29 is moved into the connecting groove 213, so that the baffle 12 limits the roller body 1, and then the rotating block 601 is rotated with the help of a tool, and the rotating block 601 drives the screw rod 6 to rotate. Since the screw rod 6 is threadedly connected to the thread groove 501, the screw rod 6 drives the pushing block 5 forward when it rotates. When the pushing block 5 is pushed forward, the ends of a pair of clamping blocks 8 with beveled surfaces can be pushed out of the movable groove 7 respectively, and inserted into the clamping groove 11, so as to fix the roller sleeve 2, thereby achieving the effect of quickly and conveniently replacing the roller sleeve 2, thereby reducing the replacement cost of the working roller.

[0038] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.
