Abstract

The present invention relates to a constant power saw cutting control device of a band sawing machine. The prior control device can not adjust the saw cutting feeding speed according to the change of saw cutting load. The constant power saw cutting control device of band sawing machine comprises a displacement sensor, a tension displacement sensor, a control circuit and a proportional reversing valve. The feeding displacement sensor is disposed in a hydraulic cylinder of a band sawing machine; the tension displacement sensor is disposed in a tension hydraulic cylinder of the band sawing machine; a signal output end of the feeding displacement sensor and a signal output end of the tension displacement sensor are respectively connected to a A / D sampling module in a control circuit; a signal output end of the control circuit is connected to a signal input end of the proportional reversing valve. In the present invention, the non-contact detection to the saw cutting load of a band saw blade is realized; and real-time feedback of the saw cutting load received by the band saw blade is realized during the saw cutting procedure; the practicability and reliability are both better than the practicability and reliability of direct detection.

Description

technical field

[0001] The invention belongs to the technical field of control, and relates to a constant power sawing control device for a band sawing machine. Background technique

[0002] As a kind of sawing machine, a band sawing machine is a machine tool that uses a band saw blade as a tool and is widely used in sawing ferrous metals, non-ferrous metals, and non-metallic materials. The system components of the band sawing machine are: bed and column parts, saw frame and belt drive part, tension part, guide part, workpiece clamping part, hydraulic transmission system, electrical control system, lubrication and cooling system. The sawing feed system of the band sawing machine is composed of a hydraulic transmission system control and an electrical control system. The hydraulic transmission system is a hydraulic circuit composed of pumps, valves, oil cylinders, fuel tanks, pipelines and other components. The electrical control system is a control circuit composed of elect...
