Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of polishing equipment, in particular to a polishing and grinding device for self-cleaning cold rolling work rolls. BACKGROUND

[0002] The cold rolling work roll is a key component of the cold rolling mill, which directly contacts the rolled piece during the cold rolling production process. It is mainly used for rolling processing of metal plates, strips and the like. By applying pressure to the rolled piece, plastic deformation is generated, so as to achieve the required thickness, shape and surface quality. In order to ensure the rolling accuracy of the work roll, the outer wall of the work roll often needs to be polished and ground. The most common work roll grinding device in the prior art is a roller conveying grinding device. The roller conveying device conveys the work roll along its axial direction through two conveying shafts, so that the work roll contacts the grinding part in a way of rotating and conveying outward. Through the cooperation of the conveying shaft and the grinding part, full-range polishing and grinding operation of the work roll can be realized.

[0003] However, the roller conveying grinding device in the prior art can only convey and grind cold rolling work rolls of a single size, which has a small application range and poor use flexibility, so it cannot better meet the work needs of production activities. At the same time, the existing polishing and grinding equipment mostly adopts open grinding, that is, the grinding part is directly exposed to the outside. Therefore, the impurities and debris generated during the polishing and grinding process will splash everywhere. The impurities splashing everywhere will pollute the working environment and need to be cleaned. At the same time, the impurities and debris generally carry a high temperature. The high-temperature debris contacting with flammable materials can easily cause a fire, which has a great safety hazard. SUMMARY

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0030] In the following description, a lot of specific details are set forth in order to give a thorough understanding of the present application, but the present application can also be implemented in other ways different from the description, and those skilled in the art can make similar generalizations without departing from the concept of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0031] Reference Figures 1 to 12For the embodiment of the present application, a polishing device for self-cleaning cold rolling work roll is provided, which comprises a base 1, a polishing unit and an isolation component 8. The polishing unit comprises two sets of adjusting components 2 arranged equally on the base 1, a polishing component 3 vertically inserted into the adjusting components 2 in the middle position, and a conveying roller 4 and a guide roller 5 arranged in parallel between each set of two adjusting components 2. The conveying roller 4 and the guide roller 5 are common conveying structure and guide structure in the prior art. The isolation component 8 is the place where the polishing operation is performed. Referring to Figure 7 The isolation component 8 is arranged between the two sets of adjusting components 2. The isolation component 8 comprises an isolation assembly 81, a shifting component 82 arranged in the isolation assembly 81, two sets of separation assemblies 83 symmetrically arranged at both ends of the isolation assembly 81, and an adjusting assembly 84 arranged on the side of the isolation assembly 81. The isolation assembly 81 is the place where the polishing operation of the whole device is performed. The separation assemblies 83 are used to control the size of the opening connected to the outside at both ends of the isolation assembly 81. Referring to Figure 9 The shifting component 82 comprises two sets of symmetrically arranged gear rings 821. The gear rings 821 are composed of a plurality of arc-shaped toothed racks connected end to end. The gear rings 821 composed of a plurality of arc-shaped toothed racks are in a ring structure. The circular gear rings 821 can drive the separation assemblies 83 to rotate through the teeth on the inner side of the gear rings 821. The rotation amplitude of the whole shifting component 82 is relatively small, specifically around 0 to 50 degrees. The staggered arrangement of the shifting component 82 can avoid mutual blocking with the connecting ears 833. The inner wall of the isolation assembly 81 is also provided with a slot matching the gear rings 821. Referring to Figure 10, the separation assembly 83 comprises a plurality of arc-shaped partitions 831 in an arc-shaped structure, and the plurality of arc-shaped partitions 831 are stacked in a ring structure in a staggered manner. The device is provided with a half gear 832 at one end of each arc-shaped partition 831, and the half gear 832 is engaged with the gear rack of the gear ring 821 to drive. A connecting lug 833 is correspondingly arranged on the side surface of each arc-shaped partition 831 near the end of the half gear 832, and the arc-shaped partition 831 is rotatably connected in the isolation assembly 81 through the connecting lug 833. The opening surrounded by the plurality of arc-shaped partitions 831 is circular, and the circular structure can facilitate the passage of the cylindrical working roller 9. At the same time, the arc-shaped partition 831 is limitingly and rotatably connected in the isolation assembly 81 through the connecting lug 833, and the plurality of arc-shaped partitions 831 correspond to the plurality of arc-shaped gear racks on the gear ring 821 one by one. The arc-shaped partition 831 is rotatable about the end provided with the connecting lug 833 under the drive of the gear ring 821 through the engagement of the half gear 832 and the gear ring 821. The plurality of arc-shaped connecting lugs 833 are synchronously rotated by the rotation of the arc-shaped partition 831, which can reduce the size of the ring opening surrounded thereby. In addition, the inner sides of the plurality of arc-shaped partitions 831 are all arc-shaped structures, so that the shape of the ring gap formed by the plurality of arc-shaped partitions 831 after being reduced is also approximately arc-shaped. The arc-shaped opening can better isolate the arc-shaped outer wall of the working roller 9, further reduce the gap between the working roller 9 and the inlet and outlet 814, and ensure that the debris cannot flow outwards.

The lower end of the polishing part 3 extends into the inlet and outlet 814 through the clearance groove 815. The inner wall of the isolation barrel 811 is a smooth circular structure, which can discharge the debris generated by polishing to the side surface of the device in the same direction in cooperation with the communication with the gear ring 821. At the same time, the smooth arc-shaped inner wall can avoid the accumulation of debris in the isolation barrel 811. The isolation barrel 811 is coaxial with the adjusting part 2, and the axes of the two are in the same straight line.

[0033] Further, referring to Figure 9 , the actuating part 82 further comprises a connecting rod 823 penetrating the adjusting groove 813, and a cross rod 822 transversely arranged between the two gear rings 821.

The screw rod 841 can push the push block 842 to move when rotating through the screw connection with the push block 842. The moving push block 842 can push the gear ring 821 to rotate in the isolation assembly 81 through the horizontal rod 822. The rotating gear ring 821 can drive the partition assembly 83 to rotate.

The slot 212 is used for limiting the extension assembly 23, so that the extension assembly 23 can only slide in and out under the limitation of the slot 212. The connecting gear 213 is used for connecting the transmission assembly 22 and the extension assembly 23.

[0037] Further, referring to Figure 4 The transmission assembly 22 comprises a limiting ring 221 rotatably connected to the limiting frame 214, a gear ring 222 arranged on the side of the limiting ring 221 and between the annular frame 211 and the limiting frame 214, and internal teeth 223 arranged on the inner side of the gear ring 222 and engaged with the connecting gear 213. The transmission assembly 22 is rotatably connected in the limiting assembly 21 through the limiting ring 221. The transmission assembly 22 can drive the connecting gear 213 to rotate through the engagement of the internal teeth 223 and the connecting gear 213.

The three sets of extension assemblies 23 are synchronously driven by the three sets of connecting gears 213, and can synchronously extend and retract, and the extension and retraction distances and directions of the three sets are the same.

[0039] Further, referring to Figure 2 The polishing component 3 includes a horizontal plate 31 arranged horizontally, a vertical plate 32 arranged vertically on the outer end of the horizontal plate 31, a polishing wheel 33 arranged on the lower end of the vertical plate 32, and a motor one 34 arranged on the horizontal plate 31. The polishing component 3 is a common grinding wheel polishing device in the prior art. The motor one 34 can drive the polishing wheel 33 to rotate and polish through a belt, so as to realize the polishing operation on the outer wall of the work roller 9 when the polishing wheel 33 contacts the work roller 9. The polishing component 3 extends the polishing wheel 33 into the isolation assembly 81 through the vertical plate 32. The vertical plate 32 can synchronously drive the polishing wheel 33 to move through the connection of the horizontal plate 31 and the extension assembly 23. Referring to the figure, in the conventional state, the distances of the polishing wheel 33, the conveying roller 4, and the guide roller 5 from the center of the limiting assembly 21 are the same. Therefore, when the three sets of extension assemblies 23 are synchronously driven to move by the adjusting component 2, the polishing wheel 33, the conveying roller 4, and the guide roller 5 are also synchronously moved and the moving distances are the same.

[0040] Further, referring to Figure 6 The end of the conveying roller 4 is connected with a driving component one 6.

The contraction rod 63 is an inwardly-contracted elastic structure. The contraction rod 63 can always tension the transmission belt 64 through cooperation with the auxiliary wheel 62, so as to ensure that the motor two 61 can drive the conveying roller 4 to rotate through the transmission belt 64. When the conveying roller 4 is moved by the extension assembly 23, the contraction rod 63 is pulled to a certain extent through the transmission belt 64, so as to extend upward to a certain extent, and the normal connection between the motor two 61 and the conveying roller 4 through the transmission belt 64 is maintained through the auxiliary wheel 62.
