Description

Material alignment device for chamfering device and one-line cutting chamfering machine having same {Material Alignment Device in Chamfering Apparatus and Integrated Cutting and Chamfering Machine with It}

The present invention relates to a material aligning device for a chamfering device, and more particularly, is provided in a chamfering device for chamfering both ends of the cut material after cutting a long raw material such as a pipe with a cutting device before chamfering the material By aligning the chamfering reference surface to the chamfering quality and the quality of the cut and chamfered product aligning device for chamfering device and a one-line cutting chamfering device having the same.

In general, a long material such as a rod or a pipe is cut into a predetermined length as necessary. At this time, the cutting of these materials is performed by an automatic cutter for cutting by using a circular cutter, such as a rotationally operated by a pneumatic cylinder or a motor, or by the operator using a rotary cutter equipped with a manual cutter. .

However, when cutting a pipe, a worker cuts a long pipe to a certain length by using a cutter, and then a separate chamfering work should be performed to prevent an accident due to the cut surface of the cut pipe. . In addition, since the pipe cut by the cutting operation must be moved to the place where the chamfering work is performed, it has disadvantages such as the cumbersome work process, waste of manpower and delay in working time.

Accordingly, a pipe cutting device capable of maintaining a uniform cutting surface of the pipe and continuously performing cutting and chamfering of the pipe has been developed, and a pipe cutting and automatic cutting and chamfering operation of the pipe can be performed. Chamfering machines were also developed.

However, in most cases, the pipe cutting device and the chamfering device are configured separately, which increases the overall size of the facility, and even the integral structure complicates the premise structure due to the connection of the pipe cutting work and the chamfering work. There are many cases where the lengths of the cut pipes do not match, and when the length is detected, a large number of defective products are found.

In addition, in the process of chamfering using the chamfering device in the chamfering device, the material is not normally aligned, there is a problem that the chamfering quality of the cut material is lowered.
