Description

Technical Field

[0001] The utility model relates to the technical field of high-precision rollers, in particular to a high-precision roller dedicated to metallurgical equipment. Background Art

[0002] The rollers used for cold rolling are generally flat rollers, which are used to roll plates and strips. In a broad sense, cold rolling rollers include working rollers in contact with the rolled pieces and backup rollers that serve as support. Since the backup rollers are a self-contained system, cold rolling rollers are often narrowly referred to as cold rolling working rollers. Cold rolling rollers must have sufficient strength, uniform high hardness and surface quality to withstand extremely high rolling forces, ensure sufficient wear resistance, and meet the precision requirements of rolled materials. Forged steel rollers that can be quenched to high hardness are used as cold rolling rollers.

[0003] For example, the patent document with the announcement number CN 210046320 U discloses a high-precision roller fixing device, including a support column, a bottom plate and a base. The base is a disc-shaped structure, the center of the base is rotatably connected to a rotating seat, the upper part of the rotating seat is rotatably connected to a rotating block, the top surface of the rotating block is welded to the center of the bottom surface of the bottom plate, and two support columns are symmetrically welded on both sides of the top surface of the bottom plate. The upper parts of the two support columns are movably connected to the roller through bearings, and the top surfaces of the two support columns are fixed with an upper cover plate for clamping the bearings by bolts. In the present utility model, the connection between the rotating seat and the base facilitates the rotation of the fixing device as a whole, and the rotational connection between the base and the rotating seat and the screws on both sides of the base that penetrate and extend to the ground facilitate the adjustment of the tilt angle of the fixing device as a whole. This can reduce installation requirements and achieve installation accuracy requirements and higher flexibility through later adjustments.

[0004] However, when this structure is used for high-precision rolling rollers specially used for metallurgical equipment, due to the limitations of its own structure, it is often only possible to perform the replacement and use operation of a single rolling roller. As a result, the entire equipment needs to be shut down for a long time during the actual replacement of the high-precision rolling rollers, affecting the overall production efficiency of the equipment. At the same time, when the equipment is replacing the high-precision rolling rollers, it is unable to achieve more stable positioning operations and cannot meet daily use needs. Therefore, it is urgent to design a high-precision rolling roller specially used for metallurgical equipment to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a high-precision rolling roller specially used for metallurgical equipment, so as to solve the problem proposed in the above background technology that when the existing structure is used for the high-precision rolling roller specially used for metallurgical equipment, due to the limitation of its own structure, it is often only possible to perform the replacement and use operation of a single rolling roller, resulting in the actual replacement process of the high-precision rolling roller, and the entire equipment needs to be shut down for a long time, affecting the overall production efficiency of the equipment. At the same time, when the equipment is replacing the high-precision rolling roller, it is unable to achieve a more stable positioning operation and cannot meet the daily use needs.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a high-precision rolling roller for metallurgical equipment, comprising a central rotating frame, wherein the upper and lower ends of the central rotating frame are fixedly connected to a connecting frame, one end of the connecting frame is fixedly connected to a mounting roller frame, and a rolling roller body is arranged inside the mounting roller frame;

[0007] A first side frame and a second side frame, the first side frame is provided at one end of the central rotating frame, the second side frame is provided at the other end of the central rotating frame, a flip motor is provided at one end of the second side frame, and an air control pump is provided at one end of the first side frame.

[0008] Preferably, the bottom ends of the first side frame and the second side frame are fixedly connected with a dismantling frame, and the top ends of the first side frame and the second side frame are fixedly connected with a running frame.

[0009] Preferably, a dismantling groove is provided at the bottom of the dismantling frame, and a positioning airbag is provided inside the running frame.

[0010] Preferably, disassembly holes are provided at both ends of the mounting roller frame, and disassembly bolts are provided inside the disassembly holes.

[0011] Preferably, rotating shaft seats are provided at both ends of the central rotating frame, and a fixing airbag is provided inside the connecting frame.

[0012] Preferably, one end of the top-fixing airbag is fixedly connected to a top-fixing plate, and a top-fixing arc groove is provided on the surface of the top-fixing plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The high-precision rolling rollers specially used for metallurgical equipment can be quickly switched up and down by the central turret, connecting frame, mounting roller frame, roller body, second side frame, flip motor, dismantling frame, dismantling groove, dismantling hole, dismantling bolt and rotating shaft seat. In actual use, the staff first installs the two sets of roller bodies inside the upper and lower mounting roller frames respectively. Then, the flip motor at one end of the second side frame can be started to drive the center turret between the first side frame and the second side frame, and quickly rotate and switch the adjustment operation at the rotating shaft seats at both ends, so that the center turret can drive the upper and lower sets of roller bodies to be quickly switched through the upper and lower connecting frames and mounting roller frames, meeting the daily replacement and use needs of the roller body. At the same time, the roller body can quickly unscrew the dismantling bolt of the dismantling hole at the dismantling groove of the dismantling frame, and then the roller body can be dismantled, which reflects the practicality of the equipment design.

[0015] The high-precision rolling rollers specially used for metallurgical equipment further improve the overall use effect of the equipment by setting the central rotating frame, first side frame, air control pump, dismantling frame, running frame, positioning airbag, top fixing airbag, top fixing plate and top fixing arc groove. In daily use, the staff can start the air control pump at one end of the first side frame to inflate the positioning airbags inside the upper and lower dismantling frames and the running frame of the second side frame, so that the positioning airbags extend into the dismantling hole at one end of the mounting roll frame to perform adaptive top fixing operations, so that the mounting roll frame and the roll body can be more efficiently positioned and tightened between the first side frame and the second side frame, avoiding the problem of active offset of the subsequent roll body during use. At the same time, when the roll body is replaced at the dismantling frame, the top fixing airbag inside the connecting frame can be started to adaptively fix the top fixing arc groove of the top fixing plate at one end to the side of the roll body, thereby ensuring the positioning auxiliary operation of the overall rapid replacement of the roll body, reflecting the comprehensiveness of the equipment design.
