Description

Technical Field

[0001] The invention belongs to the technical field of hot rolling finishing area flattening and trimming production lines, and in particular relates to a roller turning tooling for working rollers of a hot rolling flattening unit. Background Art

[0002] When the working rolls of the hot rolling skin-pass unit are being polished, they need to be rotated 360 degrees manually. Since the bearing seats of the working rolls are filled with dry oil required for the lubrication of the roll bearings, it is very difficult to manually drive the working rolls to rotate. Currently, "F" type tooling is generally used for roller rotation. Figure 1 As shown in the figure, the manual roller turning method is: clamp the front fork of the "F" type tooling to the flat head cover, and then arrange two people to hold the handle of the F type tooling together and turn the roller in a counterclockwise or clockwise direction. In the actual production process, the following problems still exist when using the "F" type tooling to turn the roller.

[0003] Since the front fork of the "F" type tooling is clamped on the flat head cover, it is easy to slip when the handle is turned hard, causing the fork to separate from the flat head cover, resulting in very low efficiency of using the "F" type tooling roller. In addition, when the F type tooling slips, the F type tooling falls and there is a risk of injuring people, and the operator is also prone to falling due to inertia.

[0004] Since the roller needs to rotate 360°, it is very inconvenient to operate the roller due to the limitations of the work space and the shape of the "F"-type tooling. Summary of the invention

[0005] The purpose of the present invention is to provide a roller turning tool for a working roll. The present invention effectively combines the mechanical structure of the flat head of the working roll to achieve the purpose of safe and easy roller turning, thereby improving the safety and operating efficiency of the roller turning operation.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a roller tooling for the working roller of a hot rolling and leveling mill unit, characterized in that it includes a circular main body, a plurality of driving teeth fixedly arranged along the periphery of the circular main body and a driving sleeve cooperating with the driving teeth; a limiting through hole matching the shape of a flat head cover of the working roller is opened on the circular main body. When in use, the limiting through hole on the circular main body is inserted into the flat head cover of the working roller, and then one end of the driving sleeve is inserted into the driving tooth. The working roller can be driven to rotate by rotating the driving sleeve.

[0007] Furthermore, the circular body and the driving teeth are integrally formed.

[0008] Furthermore, the manufacturing process of the circular body and the driving teeth as one is: using Q345 steel with a thickness of 15 mm, cutting according to the shape of the circular body and the driving teeth, and then frosting the surface to remove burrs to obtain an integrated structure that meets the requirements.

[0009] Furthermore, there are six driving teeth, which are evenly distributed along the circumferential side of the circular body.

[0010] Furthermore, the hand-held end of the driving sleeve is provided with anti-slip grooves.

[0011] The beneficial effects of the present invention are simple and quick operation, strong practicality and high safety. Specifically, the limiting through hole of the circular body of the present invention can be stably sleeved on the flat head cover of the working roll without slipping off. The driving sleeve cooperates with a plurality of driving teeth to rotate the roll, which can conveniently drive the working roll to rotate 360 ​​degrees, save time and labor, and improve the safety and efficiency of the roll operation.

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0017] like Figure 1 , 2 As shown, a roller fixture for a working roll of a hot rolling skin-pass unit of the present invention comprises a circular body 1, a plurality of driving teeth 2 fixedly arranged along the periphery of the circular body, and a driving sleeve 3 matched with the driving teeth. A limiting through hole 4 matching the shape of a flat head cover of the working roll is provided on the circular body 1. Preferably, the size of the limiting through hole 4 on the circular body 1 is 0.5-1.0 mm larger than the size of the flat head cover, which not only facilitates the tooling to be quickly inserted into the flat head cover, but also prevents the tooling from slipping on the flat head cover.

[0018] Furthermore, the circular body 1 and the driving teeth 2 are made in an integrated manner. The manufacturing process of the integrated molding is: Q345 steel with a thickness of 15 mm is cut according to the shape of the circular body and the driving teeth, and then the surface is frosted to remove burrs to obtain an integrated structure that meets the requirements. In this way, the integrated molding structure can ensure the overall rigidity, good stability and long service life.

[0019] Preferably, the driving teeth are provided with 6, and the 6 driving teeth are evenly arranged along the circumferential side of the circular body. During use, the driving sleeve 3 can switch different driving teeth for cooperation, so as to realize 360° rotation of the roller.

[0020] Furthermore, the hand-held end of the driving sleeve 3 is provided with anti-skid patterns 5 to prevent the hand-held portion from slipping and affecting the operation.

[0021] The steps of the method of use of the present invention are as follows: In the initial state, the working rolls of the hot rolling skin pass mill are Figure 4 As shown in a.

[0022] The limiting through hole of the circular body of the present invention is aligned with the flat head cover of the working roll, and pressed in, so that the circular body is stably sleeved on the flat head cover of the working roll, such as Figure 4 As shown in b.

[0023] Select a driving tooth that is convenient for operation according to the actual situation, and put one end of the driving sleeve onto the driving tooth. Figure 4 As shown in c.

[0024] The operator holds the drive sleeve and rotates it, driving the working roll to rotate a certain angle, such as Figure 4 As shown in middle d.

[0025] Take out the drive sleeve and put it on the next drive tooth, and repeat step 4 until the roller surface grinding of all working rollers is completed.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
