Problems solved by technology

[0002] In the original control system, the working feed speed remains constant during the cutting process of the billet saw, but the billet is cut as a cylinder, and its cutting power changes in a curve according to the position. Cutting a large-diameter and high-hardness billet will have a negative impact on the equipment and the saw blade. The impact is caused, the work detection current fluctuates into a sawtooth wave, and the range of change gradually increases, resulting in frequent equipment alarms, and the loss rate of the billet saw blade increases by 12%.

Embodiment Construction

[0024] The constant torque intelligent control device and operation method of the billet cutting process of the present invention will be described in conjunction with the accompanying drawings.

[0025] The design concept of the constant torque intelligent control device and operation method of the billet cutting process of the present invention is based on the fact that during the billet cutting process, the feed motor speed is gradually reduced according to the diameter of the billet, and the purpose is to reduce the torque fluctuation of the motor during the sawing process , the current fluctuation will be stable, so as to protect the equipment and reduce the loss of the saw blade. The significance of this digital-analog control is that when the sawing speed cannot be adjusted due to the solidification of the module program in the transmission aspect, the control mathematical model is built in the PLC program, and then the sawing speed can be adjusted in a large range.

Abstract

The invention provides an intelligent control device of constant torque during billet cutting. The intelligent control device includes a Siemens PLC program procedure, a servo control part, and a mechanical driving part, the Siemens PLC program procedure is converted into the intelligent control procedure formed by a PLC executable control procedure, the saw feeding speed and the billet diameter are automatically executed based on different diameter billet parameters to form a mathematical model so as to realize a control procedure with the speed variables gradually decreasing and gradually increasing, and the analysis of a mathematical model established for the billet cutting travel is carried out. Meanwhile, the invention also provides an operating method of the intelligent control device of constant torque during billet cutting. The current impact frequency converter alarm caused by cutting blank material large load can be effectively reduced, the cutting efficiency cannot be reduced, and the loss of saw blades can be reduced. The digital-analog control modifies the sawing speed given program in a large scale, and the modified feeding speed regulation system can perform optimized cutting based on blank materials in different types.

Description

technical field [0001] The invention relates to a constant torque intelligent control device and an operation method for a billet cutting process. Background technique [0002] In the original control system, the working feed speed remains constant during the cutting process of the billet saw, but the billet is cut as a cylinder, and its cutting power changes in a curve according to the position. Cutting a large-diameter and high-hardness billet will have a negative impact on the equipment and the saw blade. The impact is caused, the work detection current fluctuates into a sawtooth wave, and the range of change gradually increases, resulting in frequent equipment alarms, and the loss rate of the billet saw blade increases by 12%. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a constant torque intelligent control device and operation method for the billet cutting process, which can reduce t...
