Universal automatic pipe making machine

Abstract

The invention discloses a universal automatic pipe making machine. The universal automatic pipe making machine comprises a steel belt clamping and conveying device, horizontal rolling devices, foldingrolling devices, a shaping device, an automatic grinding device and a straightening device, wherein the steel belt clamping and conveying device, the horizontal rolling devices, the folding rolling devices, the shaping device, the automatic grinding device and the straightening device are sequentially arranged, and the horizontal rolling devices, the folding rolling devices, the shaping device and the straightening device are each of an adjustable rolling structure. The universal automatic pipe making machine is high in universality degree, when products with different pipe diameters are made, it is only needed to adjust the transverse and longitudinal positions of rolling dies of the horizontal rolling devices, the folding rolling devices, the shaping device and the straightening device,and it is not needed to replace roller shaft dies, so that the production efficiency is high; each device can be automatically adjusted by using a servo motor and a central control system, so that the automation degree of the equipment is high; and the straightening device is arranged, so that finally discharged pipes can have high straightness and excellent quality.

Description

technical field [0001] The invention relates to an automatic pipe making machine, in particular to a universal automatic pipe making machine. Background technique [0002] The traditional pipe making machine has a low degree of versatility. When producing steel pipes of different specifications and sizes, it is necessary to replace the appropriate horizontal rolls, combined vertical rolls, straightening dies and other configuration components. Multiple sets of dies are required, and the manufacturing cost is high. , At the same time, it is difficult and time-consuming to replace the mold. The horizontal height and lateral position of the traditional roller mold need to be manually adjusted, and automatic electric adjustment cannot be realized, and the degree of automation of the equipment is low. Contents of the invention [0003] According to one aspect of the present invention, a universal automatic pipe making machine is provided, including a steel strip clamping devic...
