Description of the Related Art A bar processing machine is a feed pipe that grips the rear end of a bar and feeds the bar in the longitudinal direction, and grips the bar fed by the feed pipe to reciprocate while rotating the bar. It is provided with a moving headstock, a tool rest for processing a bar that is rotated by the headstock, a guide bush for supporting the bar between the headstock and the tool rest, and the like.

際に前進し、主軸台が後退する際は棒材を介して後方に
押し戻されるようになっている。A weak forward force is applied to the feed pipe so as to follow the forward movement of the headstock, and the feedpipe advances when the headstock moves forward, and is pushed back backward through the rod when the headstock moves backward. It is like this.

たり掴んだりするようになっている。A grip device for temporarily gripping the bar is provided between the headstock and the guide bush. The grip device has scissors-like claws for sandwiching the bar, and the claws are opened and closed by an air cylinder or the like to release or grip the bar.

加工が行われる。However, the rod material penetrates through the rod material through holes of the headstock and the guide bush to reach the tool rest, and is cut by the tool of the tool rest. When the cutting is completed, the tool post retracts the tool, advances the other tool toward the bar, and separates the processed part from the bar. The headstock opens its collet chuck to perform the next processing, and retracts along the bar. At that time, the gripping device grips the bar so that the bar does not retract together with the headstock. When the headstock retracts by a predetermined stroke, the collet chuck grips a new portion of the bar and advances. Just before the headstock starts to move forward, the claws of the grip device release the bar. The tool of the tool rest approaches the tip of this bar, and processing is performed in the same manner as the previous time, and the other tool cuts off the location. After that, the same operation is repeated, and the entire length of the bar is processed.

る。However, in the conventional bar processing machine, since the bar is advanced by the feed pipe, the advancing speed of the feed pipe is faster than the moving speed of the headstock. When it is large, a large force is applied to the bar to bend the bar, and when the speed of the feed pipe is low, the bar comes off the chuck at the tip of the feed pipe. Further, when the headstock retracts during processing, the feed pipe also retracts via the rod material, and the advancing force acts on the feed pipe, which may cause the rod material to bend.

に時間がかかるという問題もある。Further, since the grip device is interposed between the headstock and the guide bush, the movement of the headstock is restricted and the processing content is also restricted. Further, there is a problem that the claw of the grip device cannot be closed while the bar is rotating, and the bar is scratched when the claw is closed. Further, it is necessary to take a timing between the operation of the collet chuck of the headstock and the operation of the claws of the grip device, and there is also a problem that processing takes time.

に止まる。Next, the headstock releases the rod and retracts to the feed roller side. At that time, for example, a stopper made of a blade for cutting off the processed portion is kept in contact with the front end of the bar. Further, the fluid is supplied from the fluid ejection hole member toward the surface of the bar, and the fluid flows toward the tool rest while being in contact with the surface of the bar. As a result, the rod is pushed toward the tool rest and its tip remains in contact with the stopper, and the rod remains at the position where the previous machining was completed, despite the backward movement of the headstock.

It is fitted inside. The fluid ejection hole member 8 has a block shape, and a fluid supply pipe 18 such as a hose is connected to a side surface of the fluid ejection hole member 8 via a connection fitting 19. A compressor (not shown), which is a source of compressed air, is provided upstream of the fluid supply pipe 18.
Is provided. A through hole 20 having a diameter larger than that of the bar A communicating with the through hole 16 of the guide bush 5 is provided in the fluid ejection hole member 8, and an annular vacant chamber 21 is provided so as to surround the through hole 20. There is. Between the annular space 21 and the through hole 20, one or a plurality of fluid ejection holes 22 that are inclined toward the front side are provided.

6 flows forward, joins the air flow a sucked from the inlet of the through hole 20 of the fluid ejection hole member 8, and blows out from the slot 17 toward the tip of the bar A. This air flow a flows while contacting the surface of the bar A, and urges the bar A forward. When the fluid ejection hole member 8 is arranged on the rear end side of the guide bush 5 as in this embodiment, the fluid flows in the guide bush 5, so that the contact area with the bar A is increased accordingly, and It is possible to urge A more strongly to the front and to prevent its retreat accurately.

And hits the stopper 4a to stop. Headstock 2
Has retracted to the feed roller 6 side, grips the new material of the bar A, and advances toward the tool rests 3, 4. As a result, the tip portion of the new material is cut by the cutting tool 3a of the one tool rest 3.

That is, the cutting blade 3a moves backward together with the tool rest 3, the cutting blade 4a advances toward the bar A by the tool rest 4, and cuts the finished part from the bar A. The cut-off blade 4a remains at that position even after the cut-off, and functions as a stopper.

つ。In the headstock 2, the collet chuck 2a is opened to perform the next processing, the rod A is released, and the feed roller 6 is released.
Retreat to the side. At that time, a valve (not shown) provided in the middle of the fluid supply pipe 18 is opened and the air is blown by the guide bush 5.
Flows in. The air flow a flows at a high speed while contacting the surface of the bar A, and pushes the bar A forward due to friction or the like, and the bar A stops by hitting the cutting tool 4a whose end is a stopper. Therefore, the bar A moves relative to the headstock 2 even if the headstock 2 retracts, and maintains the position at the end of machining.

る。When the headstock 2 retracts by a predetermined stroke L, the collet chuck 2a grips a new portion of the bar A and advances. Prior to this forward movement, the tool post 4 moves, the cutting tool 4a moves away from the bar A, and the cutting tool 3a approaches the bar A. When the headstock 2 is moved forward, air flow or the like is normally cut off, but since the collet chuck 2a holds the bar A, it does not matter if the flow continues. When the tip portion of the bar A is processed in the same manner as the previous time, the cutting blade 4a cuts off the product portion from the bar A.
After that, the same operation is repeated and the bar A is processed.

It spouts from 7 toward the tip of the bar A. Thus, when the processing for one bar A is completed, the residual material discharge device 7
Operates to remove the remaining material of the bar A from the headstock 2. When the residual material is removed, a new material of the bar material A is supplied thereafter, and is supplied to the headstock 2 by the feed roller 6.

Further, since the conventional grip device can be omitted, the headstock can be brought close to the guide bush and the stroke of the headstock is not restricted. Further, by omitting the conventional feed pipe and grip device, the structure of the bar processing machine can be downsized and simplified.
