Description

Technical Field

[0001] This utility model relates to the field of rolling mill technology, specifically to a high-quality bar rolling mill device. Background Technology

[0002] The rolling mill roll is the main working component and tool that causes continuous plastic deformation of metal. The roll mainly consists of three parts: the roll body, the roll neck, and the shaft end. The roll body is the middle part of the roll that actually participates in the rolling of the metal. It has a smooth cylindrical or grooved surface. The roll neck is mounted in a bearing and transmits the rolling force to the stand through the bearing housing and the pressing device. The drive end shaft end is connected to a gear housing via a connecting shaft, transmitting the rotational torque of the motor to the roll.

[0003] Currently, in the use of bar mill rolls, the bar is rolled into shape in the groove. During long-term rolling operation, the groove surface of the roll will be worn, which will affect the rolling quality of the bar. When the groove is worn, the entire roll usually needs to be replaced, which is costly and wasteful of resources. Utility Model Content

[0004] The purpose of this utility model is to provide a high-quality bar mill roll device, which has the advantage that only some parts need to be replaced when the groove is worn, without the need to replace the whole roll, effectively reducing the cost of replacing the roll and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-quality bar mill roll device, comprising:

[0006] The assembly includes an installation mechanism, a roll body mechanism, and a rolling mechanism. The installation mechanism comprises a roll neck and an installation connecting plate. The roll neck is installed at the center of one end face of the installation connecting plate. The roll body mechanism is installed between the installation connecting plates and includes a roll body. Both end faces of the roll body are provided with an array of first threaded holes. The rolling mechanism is mounted on the roll body and includes a metal cylinder. A circular sleeve hole is provided on the metal cylinder, which is sleeved on the outside of the roll body, and the roll body is located inside the circular sleeve hole. An array of fixing plates is installed on the side end of the metal cylinder, and a second installation hole is provided on the fixing plate.

[0007] When using the high-quality bar rolling mill device of this utility model...

[0008] The roll neck is installed in the bearing of the rolling mill. During operation, the rolling mill causes the present invention to rotate. During the rotation, the bar passes through the rolling groove and is rolled into shape under the action of the rolling groove. When the rolling groove is worn and cannot perform normal rolling work, the present invention can be removed from the rolling mill, and then the second fixing bolt can be removed by rotating and disassembling. The fixing of the rolling mechanism can then be loosened, and the rolling mechanism can be removed along the roll body mechanism. Then, a new rolling mechanism can be installed according to the above operation.

[0009] Preferably, there are two mounting mechanisms, which are symmetrically distributed about the roller body mechanism.

[0010] Preferably, the side end of the mounting connecting plate is provided with a first mounting hole corresponding to the first threaded hole, and a first fixing bolt is installed in the first mounting hole and the first threaded hole.

[0011] Preferably, there are four rolling mechanisms, and the four rolling mechanisms are evenly and equidistantly distributed about the roll body.

[0012] Preferably, the outer surface of the metal cylinder is provided with a rolling groove.

[0013] Preferably, the roll body has a second threaded hole corresponding to the second mounting hole, and a second fixing bolt is installed in the second mounting hole and the second threaded hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] When the rolling groove wears down and cannot perform normal rolling operations, this utility model can be removed from the rolling mill, and then the second fixing bolt can be removed by rotating it to loosen the fixing of the rolling mechanism. The rolling mechanism can then be removed along the roll body mechanism. Only the rolling mechanism needs to be replaced, without replacing the entire roll, which reduces the replacement cost. The replacement operation is simple and quick, and convenient for bar rolling. Attached Figure Description
