Roll finishing device

Abstract

The invention discloses a roll finishing device. The roll finishing device comprises a rolling wheel, a bearing block, a guide rail, a linear bearing, a cylinder guide rod connected with the guide rail as well as a belleville spring group and a sliding bearing which are mounted on the cylinder guide rod, wherein a rotary shaft is arranged in the bearing block, the rolling wheel is fixed at the lower end of the rotary shaft, the guide rail is inserted into the linear bearing and mounted on the bearing block, the linear bearing is inserted into a casing and fixed at the front end of the casing, one end of the cylinder guide rod is inserted into the guide rail, the other end is connected with a pressure sensor, the outer side of the pressure sensor is mounted on a regulating ring which is connected onto the casing, a first pressure bearing pad and a second pressure bearing pad are fixed on the cylinder guide rod, a gap between the first pressure bearing pad and the second pressure bearing pad is sleeved with the belleville spring group, the sliding bearing is arranged on the second pressure bearing pad, and the first pressure bearing pad is propped against the guide rail. The roll finishing device is compact in structure, rolling pressure input by the regulating ring is transmitted to a rolling cutter accurately, and pressure component loss is avoided.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment engineering, in particular to a rolling processing device. Background technique [0002] Rolling processing is to apply a certain pressure to the surface of the workpiece through a certain form of rolling tool, and use the plastic deformation of the metal at room temperature to achieve the purpose of finishing and strengthening the workpiece. Among the process parameters of rolling processing, the appropriate rolling pressure is the key factor to determine the quality of rolling. Therefore, during the rolling process, it is not only necessary to accurately control the size of the rolling pressure, but also to ensure that the rolling pressure does not fluctuate in a large range. [0003] The rolling pressure is usually transmitted to the rolling tool by using a spring as the working medium. In the existing patent literature, in the patent text of "Ultrasonic Rolling Device with Meas...

Problems solved by technology

The disadvantage of this patent is that during the rolling process, the coil spring bears the impact and vibration fed back to the rolling tool by the rotation of the workpiece at the same time

Because the natural frequency of the coil spring is low, it is easy to transmit high-frequency vibration; and the damping ratio of the coil spring is usually small, so it will have a high
