Bearing steel pipe flaw detection production line

Abstract

The invention discloses a bearing steel pipe flaw detection production line. A charging device is arranged at the front end of a conveying bracket, a low-frequency eddy current detecting device has a structure that a U-shaped detecting bracket is fixed on the conveying bracket, a detecting sliding block is arranged in the detecting bracket, a low-frequency eddy current detector is fixed on the detecting sliding block, a pressure wheel is arranged on the detecting sliding block and compressed on a bearing steel pipe, the upper end of a worm is hinged on the detecting bracket, the lower end of the worm is screwed on the detecting sliding block, the worm is meshed with a worm wheel, the worm wheel is arranged in a worm wheel box, a hand wheel is fixed on a rotating shaft of the worm wheel; the structure of a high-frequency eddy current detecting device is the same as that of the low-frequency eddy current detecting device. According to the bearing steel pipe flaw detection production line, during charging, semi-automatic charging is adopted, thus the labor intensity is lightened; during discharging, the bearing steel pipe falls onto a receiving belt and cannot hardly collide with the receiving frame; the high-frequency eddy current detecting device is adopted and is capable of detecting whether a flaw exists on the inner wall of the bearing steel pipe, thus the flaw detection effect is relatively good.

Description

Technical field: [0001] The invention relates to the technical field of bearing steel pipe production, and more specifically to a production line used for flaw detection of bearing steel pipes in the production process of bearing steel. Background technique: [0002] Bearing steel pipes need to be inspected for the quality of the bearing steel pipes before they leave the factory. The existing bearing steel pipe testing device uses a low-frequency eddy current flaw detector to detect whether there are metal cracks on the bearing steel pipe surface after placing the bearing steel pipe on a rolling conveyor belt. , And then manually unload and sort. The difference is: it adopts manual feeding, low production efficiency and high labor intensity. When unloading, the unqualified bearing steel pipe is removed by the unloading device, and the removed bearing steel pipe is easy to connect when blanking. Hard collision of the material rack can easily damage the quality of the bearing stee...

AI Technical Summary

Problems solved by technology

The disadvantage is that it adopts manual feeding, which has low production efficiency and high labor intensity. When unloading, the unqualified bearing steel pipe is removed by the unqualified bearing steel pipe. The hard collision of the material rack is easy to damage the quality of the bearing steel pipe

It can only detect flaws on the surface of the bearing steel pipe, making the flaw detection of the bearing steel pipe incomplete, and needs further improvement
