Problems solved by technology

The actual use shows that the loading of the proportional relief valve is affected by the characteristics of the valve itself and the load volume. The dynamic characteristics of the system are relatively poor and cannot meet the requirements of followability. However, the use of servo valve loading, the system composition is complicated, the cost is relatively high, and it is harmful to the use environment. Demanding and difficult to maintain
In addition, in the systems currently used, the inertial force has a relatively large influence on the pressing force, and there is no compensation

Abstract

A constant-pressure and -power control system for pressing abrasive disc downward to grind steel bellite is composed of a loading unit with a master motor for driving abrasive disc, a hydraulic unit for controlling the pressing down of abrasive disc and with a motor having the frequency-varying speed regulation, and a control unit for controlling the output power of master motor. The pressing-down force of abrasive disc is controlled by three-way proportional valve to release pressure.

Description

1. Technical field [0001] The invention belongs to steel billet grinding machines, in particular to a steel billet grinding machine grinding wheel pressing constant pressure constant power composite control system. 2. Background technology [0002] At present, most of the reduction force control systems of billet grinding machines produced at home and abroad adopt the pressure control system loaded by servo valve, and there are also pressure control systems loaded by electro-hydraulic proportional relief valve, but these two loading systems have some shortcomings. The actual use shows that the loading of the proportional relief valve is affected by the characteristics of the valve itself and the load volume. The dynamic characteristics of the system are relatively poor and cannot meet the requirements of followability. However, the use of servo valve loading, the system composition is complicated, the cost is relatively high, and it is harmful to the use environment. It is d...
