Abstract
The invention discloses a quality detection technology. Flange quality inspection mainly comprises labor quality inspection and photograph contrast quality inspection. The labor quality inspection belongs to preliminary detection and is mainly used for identifying unqualified flanges with obvious defects. Flanges subjected to the labor quality inspection enter a photograph-contrast detection step for precision detection. In the photograph-contrast detection step, front and back surfaces of each flange are pictured to obtain a front surface picture and a back surface picture, the front surface picture and the back surface picture are contrasted with a front surface standard picture and a back surface standard picture pre-stored in a control system respectively, and the contrast ratio of the front surface picture to the front surface standard picture and the contrast ratio of the back surface picture to the back surface standard picture are viewed, and thus the quality of the flange is detected. The quality detection technology detects the flange quality, ensures the excellent quality of delivered flanges, and provides good guarantee for maintaining the reputation and the economic benefit of a factor. The quality detection technology is good in flange quality detection effect and is worth popularizing.

Aforesaid a kind of quality testing technique, is characterized in that, standard against regulation in described step (6) is: reverse side photo and contrast≤95% of reverse side standard film be prestored into.
Beneficial effect of the present invention: a kind of quality testing technique provided by the invention, first by cleanup step, the chip produced when producing flange is cleaned out, and by cleaning step profound cleaning further, and dry after cleaning, provide convenient for follow-up flange detects.Quality inspection for flange mainly comprises artificial quality inspection and photo comparison's quality inspection, artificial quality inspection belongs to Preliminary detection, be mainly used in the substandard products flange identifying that those have open defect, these substandard products flanges there is the detectable defect of macroscopic appearance, such as flange surface out-of-flatness, flange there are bur or gap etc., after weeding out these substandard products flanges, remaining flange enters contrast detecting step of taking pictures, this step is accuracy detection, to the front of flange, reverse side is taken pictures respectively and is obtained full face, after reverse side photo, by full face, reverse side photo respectively with the positive criteria sheet pre-deposited in the controls, reverse side standard film contrasts, see the contrast of full face and positive criteria sheet, the contrast of reverse side photo and reverse side standard film, if contrast >=95% of full face and positive criteria sheet and contrast >=95% of reverse side photo and reverse side standard film, then illustrate that flange is certified products, may be used for follow-up sales, if contrast >=95% of contrast≤95% of full face and positive criteria sheet or reverse side photo and reverse side standard film, then illustrate that flange is underproof substandard products, needs again to process perfect.The quality of this quality testing technique to flange detects, and the excellent quality of flange of guaranteeing to dispatch from the factory, have good guarantee for the prestige and economic interests safeguarding producer, this technique is respond well for flange quality testing, is worthy to be popularized.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
A kind of quality testing technique, comprises the following steps:
Step (1), cleans out the chip on the flange machined; In this step, the mode of cleared of debris is utilize blower fan to dispel chip on flange, and blower fan produces powerful wind-force through flange thus the chip taken away on flange.
Step (2), puts into cleaning fluid by the flange after cleared of debris and cleans; In this step, cleaning fluid is the potpourri of clean-out system and water, can wash the dirt on flange.
Step (3), carries out drying to the flange cleaned up in step (2); Compare in dry environments after being cleaned up by flange and be beneficial to follow-up detection operation, drying mode is that nature dries.
Step (4), utilizes and manually carries out preliminary quality inspection to dried flange, weed out substandard products flange against regulation; Situation against regulation in this step has: flange has bur or gap, flange surface out-of-flatness.As long as there is the defect that naked eyes can identify be substandard products flange.
Step (5), the flange of not rejecting in step (4) is placed smooth one by one successively, taken pictures in the front of flange and obtain full face, and one by one full face and the positive criteria sheet pre-deposited are contrasted, weed out substandard products flange against regulation; Standard against regulation in this step is: full face and contrast≤95% of positive criteria sheet be prestored into, namely with positive criteria sheet for benchmark, detect the registration of full face and positive criteria sheet, if registration≤95% of the two, it is then underproof flange, if the two registration >=95%, be then the qualified flange in front, enter follow-up reverse side detecting step.
Step (6), by the flange of not rejecting in step (5) one by one successively turn-over to the reverse side of flange, the reverse side of flange is taken pictures and obtains reverse side photo, and one by one reverse side photo and the reverse side standard film pre-deposited are contrasted, weed out substandard products flange against regulation; Standard against regulation in this step and front similar, for: reverse side photo and contrast≤95% of the reverse side standard film be prestored into, same with reverse side standard film for benchmark, detecting the registration of reverse side photo and reverse side standard film, if registration≤95% of the two, is then underproof flange, if the two registration >=95%, be then the flange that reverse side is also qualified, now this flange have passed all detections, is qualified flange.
Step (7), by the qualified flange vanning of not rejecting in step (6).By for sale after the flange vanning of above quality inspection.
This kind of quality testing technique, is first cleaned out the chip produced when producing flange by cleanup step, and by cleaning step profound cleaning further, and dry after cleaning, provide convenient for follow-up flange detects.Quality inspection for flange mainly comprises artificial quality inspection and photo comparison's quality inspection, artificial quality inspection belongs to Preliminary detection, be mainly used in the substandard products flange identifying that those have open defect, these substandard products flanges there is the detectable defect of macroscopic appearance, such as flange surface out-of-flatness, flange there are bur or gap etc., after weeding out these substandard products flanges, remaining flange enters contrast detecting step of taking pictures, this step is accuracy detection, to the front of flange, reverse side is taken pictures respectively and is obtained full face, after reverse side photo, by full face, reverse side photo respectively with the positive criteria sheet pre-deposited in the controls, reverse side standard film contrasts, see the contrast of full face and positive criteria sheet, the contrast of reverse side photo and reverse side standard film, if contrast >=95% of full face and positive criteria sheet and contrast >=95% of reverse side photo and reverse side standard film, then illustrate that flange is certified products, may be used for follow-up sales, if contrast >=95% of contrast≤95% of full face and positive criteria sheet or reverse side photo and reverse side standard film, then illustrate that flange is underproof substandard products, needs again to process perfect.The quality of this quality testing technique to flange detects, and the excellent quality of flange of guaranteeing to dispatch from the factory, have good guarantee for the prestige and economic interests safeguarding producer, this technique is respond well for flange quality testing, is worthy to be popularized.
