Description
Technical Field
The invention relates to a sawing machine cutting system.
Background
The steel with different cross-section shapes, such as metal round steel, formed by hot rolling, forging or cold drawing and other processing technologies is divided into fixed lengths by adopting a sawing mode at present, so that the steel is a proper material blank for subsequent processing. However, because the processing technology of the raw materials often has larger processing errors, the cross-sectional areas of the metal steel are different, the volumes of the metal materials after each sawing are different under the condition that the sawing length is a fixed value, and under some working conditions with higher precision requirements, the material blanks often have difficulty in meeting the precision requirements.
At present, the sawing machine industry does not have an effective method for measuring the section data only by manpower frequently, and only estimates the section data by an ideal calculation method, so that the next sawing length is obtained, the processing efficiency is low, and the error is high.

The sawing machine equal volume sawing control system is based on an image processing technology, calculates the cross-sectional area of a material before sawing each time through the image processing technology, obtains the feeding length of next sawing, and realizes equal volume sawing of the material.
The sawing machine equal volume sawing system comprises a material conveying device and a sawing device which are arranged on a frame, wherein the material conveying device comprises a hydraulic element 1 and a clamping element 3 driven by the hydraulic element, and the clamping mechanism 3 clamps sawing materials to advance; the sawing device comprises a saw blade 5; the method is characterized in that: the frame is also provided with an LED light source 6, a pneumatic spray gun 7 and a CCD camera 8 which are aligned with the section of sawing materials on the sawing device, the data output end of the CCD camera 8 is connected with an image acquisition system 9, and the control signal input end of the LED light source 6 and the control signal input end of the pneumatic spray gun 7 are respectively connected with the image acquisition system 9;
the image acquisition system 9 comprises a storage module for sawing material section standard images, a comparison module for comparing the sawing material section images shot by the CCD camera 8 with the sawing material section standard images, and an instruction output module; when the section images of the sawing material shot by the CCD camera 8 are different from the standard section images of the sawing material, the instruction output module controls the pneumatic spray gun 7 to spray so as to remove residual saw dust on the section of the sawing material, and instructs the CD camera 8 to extract the section images of the sawing material again for comparison by the comparison module; when the section image of the sawing material shot by the CCD camera 8 is not different from the standard section image of the sawing material, the image acquisition system 9 outputs the section image of the sawing material to the upper computer 10;
the image acquisition system 9, the upper computer 10 and the sawing machine automatic control system 11 are sequentially connected, the signal output end of the sawing machine automatic control system is connected with the control signal input end of the hydraulic element 1, and the hydraulic element 1 is communicated with the hydraulic loop of the clamping mechanism 3;
the image acquisition system 9 calculates the cross-sectional area according to the saw cutting material cross-sectional image output by the upper computer 10, obtains the next saw cutting length, and feeds the next saw cutting length to the sawing machine automatic control system 11;
the sawing machine automation control system 11 controls the hydraulic element 1 such that the material conveying means conveys the sawing material of the next sawing length to the sawing means.
The working principle of the invention is as follows: firstly, an LED light source is used for irradiating the section of the sawing material, and the principle that the metal material is easy to generate reflection light is used for weakening a background picture of the material in the image extraction process and presenting a regular section image. Before each sawing of the material, the image acquisition system performs image extraction on the saw cut section, and stores the saw cut section as a standard image for judging whether errors exist in subsequent image extraction.
The CCD camera is utilized to shoot the section of the saw cut material after illumination, and a large amount of image data is sent to the image acquisition system for analysis, and as a large amount of saw dust is generated in the saw cut process and is cooled by adopting cooling liquid, the saw dust residues and the cooling liquid adhesion easily occur on the section of the saw cut material, and errors are generated in image processing. Therefore, the image acquisition system compares the image acquired by the CCD camera with the original image, judges whether the boundary of the section image has deviation, and judges whether sawdust residues or cooling liquid adhesion exists according to the deviation.
When the image acquisition system considers that sawdust residues or cooling liquid adheres, the pneumatic spray gun positioned at the front section of the cutting section is directly controlled to instantly spray a large amount of high-pressure gas, the sawdust or the cutting liquid remained on the material section is blown away, then the image is extracted again through the CCD camera, the image is analyzed again through the image acquisition system, and if the boundary of the cross-section image of the material meets the boundary requirement of the cross-section image of the original material, the next sawing state can be considered.
