Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cold-drawn pipe crack detection, and more particularly to a cold-drawn pipe crack detection and sorting device. BACKGROUND

[0002] As an important branch of steel pipe production technology, the cold-drawn pipe has a unique forming process compared with the hot-rolled pipe. The cold-drawn pipe is processed on a specific cold-drawing machine by a multi-pass cold-drawing process during the expansion stage of the blank or raw pipe. During the cold-drawing process, the steel pipe is subjected to the combined action of drawing force, normal pressure and friction force, and sequentially undergoes key stages such as reduction of diameter, wall reduction and sizing, thereby producing plastic deformation and changing the internal structure, and finally obtaining a product with high precision and specific performance.

[0003] In the production and detection process of the cold-drawn pipe, in order to reduce the friction between the pipe body and the die and improve the ultrasonic detection effect, a proper amount of lubricant needs to be applied to the surface of the pipe body. However, if the local lubrication on the surface of the pipe body is insufficient, it will cause uneven deformation of the surface, and when the ultrasonic detection technology is used subsequently, the detection coverage is low, and the propagation of the detection wave is hindered, making it difficult to accurately detect the cracks or other defects on the surface of the steel pipe, seriously interfering with the accuracy and reliability of the product quality detection, and causing defective products to mix with qualified products, affecting the product qualification rate.

[0004] In addition, when sorting the cold-drawn pipe, the current common method is to guide the product to fall into the collection chamber through a guide rail. When the cold-drawn pipe collides with the bottom of the collection chamber or other cold-drawn pipes during the falling process, it may cause secondary surface damage, resulting in increased production cost and intensified product loss, and it is difficult to ensure that the quality of the cold-drawn pipe meets the standard requirements.

The device comprises a support, a driving assembly arranged on the support, and a detection assembly connected with the output shaft of the driving assembly; a sorting assembly is arranged at the bottom of the support, the sorting assembly comprises a driving shaft arranged horizontally on the support and a sorting groove for containing the cold-drawn pipe, the driving shaft and the sorting groove are arranged in parallel, and the driving shaft abuts against the cold-drawn pipe placed in the sorting groove; a first driving unit and a second driving unit are arranged at the bottom of the support, the output shaft of the first driving unit is connected with the driving shaft, the output shaft of the second driving unit is connected with the sorting groove, and the detection assembly is electrically connected with the second driving unit; a conveying belt assembly is arranged on one side of the sorting groove.

[0006] Preferably, the cross section of the sorting groove is arc-shaped.

[0007] Preferably, the sorting groove is arranged below the detection assembly.
