Embodiment 1

[0023] Such as figure 1 As shown, a method for controlling the stop angle of the roll head of a hot rolling roll grinder uses the bedside motor encoder to collect the current rotation angle and speed of the roll, and the signal of the positioning limit is switched on and off to correct the current roll rotation angle, and the roll stop command is executed when the angle is matched. The specific control method is as follows:

[0024] 1) When the roll grinding is qualified and meets the roll unloading conditions, the automatic control system gives the roll unloading command, and the grinding machine automatically returns to the initial grinding position;

[0025] 2) The automatic control system judges the preset data of the stop angle of the roll, and the preset value of the stop angle of the roll is set to 90°;

[0026] 3) The encoder KTY84ENCODER_D01_2048_SR installed on the bedside motor collects the angle and speed of the roll rotation. The numerical control system reads th...

[0032] Such as figure 1 As shown, a method for controlling the stop angle of the roll head of a hot rolling roll grinder uses the bedside motor encoder to collect the current rotation angle and speed of the roll, and the signal of the positioning limit is switched on and off to correct the current roll rotation angle, and the roll stop command is executed when the angle is matched. The specific control method is as follows:

[0033] 1) When the roll grinding is qualified and meets the roll unloading conditions, the automatic control system gives the roll unloading command, and the grinding machine automatically returns to the initial grinding position;

[0034] 2) The automatic control system judges the preset data of the stop angle of the roll, and the preset value of the stop angle of the roll is set to 0°;

[0035] 3) The encoder KTY84ENCODER_D01_2048_SR installed on the bedside motor collects the rotation angle and speed of the roll. The numerical control system reads the...

Abstract

The invention relates to a method for controlling a roller head stop angle of a hot rolling roller grinder. The method is characterized in that the existing rotation angle and existing rotation speed of a roller are collected through a machine head motor coder, a limit-positioning signal is on and off so as to correct the existing rotation angle, and a roller stop order is controlled when it is calculated that the angle is matched. According to the method for controlling the roller head stop angle of the hot rolling roller grinder, the roller head stop position of the roller can meet preset angle requirements after a program is executed every time, control deviation of the stop angle is within + / -2 degrees, and positioning is accurate. The automatically-processed qualified roller can be directly lifted down from the roller grinder and placed on an installing railway of a rolling mill in case the roller is installed to be used. The need of secondary working of manual adjustment by operators is avoided, so that machining with the roller grinder is smoother, and the problem of installing due to incorrectness of a roller head angle is avoided.

Description

technical field [0001] The invention relates to an automatic control method for roll stop of a numerically controlled roll grinder, in particular to a method for controlling the stop angle of a roll head of a hot roll grinder. Background technique [0002] The finishing mill unit of the hot rolling and continuous rolling production line has relatively high requirements for the installed rolls, especially the strict requirements for the installation angle of the roll head. If the angle is not correct, it will cause inaccurate installation and affect the production rhythm of the rolling line. Since the rolls are processed on the CNC roll grinder to be qualified, they are put on the installation track for installation and use. After the roll grinder is processed, the angle of the roll head directly corresponds to the installation angle. If the grinding machine does not control the angle of the roll head correctly, it will Will directly affect the installation. The CNC grinding...
