Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a cutting apparatus for cutting a round bar made of a metal such as stainless steel or iron to a predetermined length, and more particularly to an automatic cutting apparatus for automatically feeding a round bar and automatically cutting a supplied round bar To provide ease of use.

Generally, the round bar is widely used as a basic material in various fields such as various construction members used in a construction site or a factory for manufacturing a valve body depending on the use range.

In order to cut such a round bar into a predetermined length, it is conventionally cut using a manual saw blade or an automatic saw blade using electricity after marking the position where the cut is conventionally performed. The efficiency is very low, and dangerous situations may arise in which a floating element is generated due to fragmentation in cutting the round bar.

Therefore, in order to solve the above-mentioned problems, recently, a cutting device for cutting a round bar into a certain length has been used. However, this requires complicated operations because the operator has to manually operate various steps in order to cut the round bar. There is a problem that the productivity drops because the worker has to supply another round bar.

Accordingly, there has been proposed a feeder that automatically feeds the round rods to the cutting apparatus one by one using a moving chain in a state where a large number of round rods are stacked on the load chain. However, this is because the feeder is separately provided in the cutting apparatus, And there are several steps for supplying the cutting device, so that the cutting operation speed can not be made quickly and the productivity is lowered.

Registration No. 10-0807072 (2008.02.18) Registration No. 10-0992195 (October 29, 2010)

Accordingly, the present invention is automatically supplied one by one in a state in which a large amount of round rods are loaded, and at the same time, it is cut to a certain size by an automatic line through a cutting device, thereby improving workability and productivity.

In order to achieve the above object, according to the present invention, there is provided a conveying apparatus for conveying a round bar supplied to a conveying rail to a cutting device, a conveying rail for conveying the round bar supplied to the conveying rail to a cutting device, And a cutting device for cutting a round bar to be fed through the feeder power section to a predetermined size after the forward and backward cutting for cutting the feed bar is completed, So that a series of processes from the supply of the round bar to the cutting process are automatically performed.

Therefore, according to the present invention, when the round bar is cut to a certain size and the round bar is cut, the automatic bar feed device is operated as an automated line to improve the productivity of raw materials required for product production So that mass production is possible, which is economical effect.
