BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a material supply apparatus and an integral cutting-type chamfer provided with the material supply apparatus. More particularly, the present invention relates to a material supply apparatus for continuously supplying a raw material having a long length, And thus, the raw material is stably supplied, and the cutting operation and the chamfering operation are sequentially and simultaneously performed. Thus, the productivity is greatly improved.

Normally, a long material such as a rod or pipe is cut to a certain length as needed. At this time, cutting work of these materials is performed by an automatic cutting machine that cuts using a circular cutter or the like rotated by a pneumo-hydraulic cylinder or a motor, or an operator performs work using a rotary cutter provided in a manual cutting machine .

However, at the time of cutting the pipe, a worker cuts a pipe having a long length to a predetermined length using a cutting machine, and then performs a separate chamfering operation to prevent an accident caused by 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, there is a disadvantage that the work process is troublesome and the waste of the workforce and the working time are delayed

Accordingly, there has been developed a pipe cutting apparatus capable of uniformly maintaining the cutting face of the pipe and continuously performing the cutting and chamfering work of the pipe, and also a pipe cutting apparatus capable of automatically performing the cutting operation and chamfering operation of the pipe, A chamfer was also developed.

However, in most cases, the pipe cutting device and the chamfering device are formed separately, so that the overall size of the equipment becomes large. Even in the case of the integral structure, the overall structure is complicated due to the connection between the cutting operation and the cutting operation. Many cases where the lengths of the cut pipes do not coincide with each other, and a large number of defective products are found when the length is detected.

In addition, since the process of moving the cut pipe from the cutting device to the chamfering device is often carried out sequentially and not automatically, the work time is delayed and the workforce is wasted. In addition, a plurality of pipes stacked one at a time are separated and supplied to the cutting device And it is not easy to continuously supply the pipe by the cutting device.

[

When the raw material S is stopped near the end of the raw material supplying unit 100, the lifting and lowering unit 240 of the raw material conveying unit 200 moves the plunger 220 downward to the rear end of the raw material S . In this state, the horizontally moving part 230 horizontally moves along the guide rail 210 so that the pusher 220 horizontally moves the raw material S to the processing part. Accordingly, the raw material S is supplied to the machining portion via the raw material guide portion 300. [ As described above, when the feeding of the raw material S is completed, it is a matter of course that the plunger 220 is raised by the lifting / lowering moving part 240 and moved to the initial position by the horizontal moving part 230. [

The raw material guide part 300 guides the raw material S to the processing part by using a pair of guide rollers 310 arranged in the horizontal direction and at the same time the end part of the raw material S is stably . At this time, the pair of spacing adjusting gears 320 provided in the raw material guide unit 300 are rotated to rotate the guide roller 310 in the horizontal direction to correspond to the diameter of the raw material S, (310) feeds the raw material (S) to the machining portion while rotating the raw material (S).
