Problems solved by technology

Conventional machine tools use a mechanical reducer with single input shaft and multiple output shafts. Due to the influence of processing and assembly accuracy, the rotation accuracy of each output shaft is unstable, making the quality of the processed workpiece not stable enough, and the accuracy is difficult to improve, which cannot meet the higher requirements of users. Require

Abstract

The invention relates to the field of metal rolling, in particular to a numerical control roll machine. The numerical control roll machine comprises machine bodies including the upper machine body and the lower machine body, and further comprises a servo main shaft driving system, a proportional servo hydraulic sliding base feeding system and a numerical control system. The servo main shaft driving system, the proportional servo hydraulic sliding base feeding system, the numerical control system and the upper machine body are all fixed to the lower machine body, machine body side walls are arranged at the two ends of the upper machine body respectively, and the machine body side walls and the upper machine body are of an integrated structure. According to the numerical control roll machine, high-precision synchronous rotation of double main shafts is achieved, completely independent control over the two main shafts is achieved, automatic tooth position alignment can be achieved, and machining precision of the machine is improved.

Description

technical field [0001] The invention relates to the field of metal rolling, in particular to a numerically controlled rolling machine. Background technique [0002] The rolling mill is an advanced and advanced machine that uses the plasticity of certain metal materials at cold or normal temperature to extrude the rotary billet through the rotating rolling die under the action of external force for thread processing and spline parts processing. High-efficiency, high-quality, low-consumption chipless processing machine tools. According to the number of rolling die shafts that can be installed, it can be divided into single-slide rolling mill, two-axis rolling mill and three-axis rolling mill. [0003] The accuracy of the workpiece processed by the rolling machine is affected by the rotation accuracy and synchronization accuracy of each spindle. Conventional machine tools use a mechanical reducer with single input shaft and multiple output shafts. Due to the influence of proc...
