BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel material processing machine, and more particularly to a steel material processing machine characterized by a center gauge for positioning a work to a work processing part provided with a plurality of dies.

[0002]

2. Description of the Related Art Conventionally, in a steel material processing machine in which a unit die is mounted on a turret table as a work processing portion, the work is positioned at a work processing position by contacting the work with a center gauge attached to a work support. It is common to do. This center gauge is usually provided detachably on a work table on which a work is placed by means of a pin.

[0003]

However, in such a conventional technique, when processing is performed by using a die unit such as when cutting a flat bar or a channel among steel materials, a die is used. Since the unit interferes with the center gauge, the center gauge must be removed and cutting must be performed. For this reason, when cutting short materials, there is no center gauge serving as a reference, so that it is difficult to position the work and it is difficult to cut the work at a right angle.

The purpose of the present invention is to pay attention to such a conventional technique. A steel working machine capable of positioning a work at a predetermined position even when processing a short work is provided. To provide.

[0005]

In order to achieve the above object, a steel working machine according to the present invention comprises a work processing section provided with a plurality of dies and a work support for supporting the work. A steel material processing machine that can be freely moved toward and away from the workpiece, wherein a center gauge provided on the workpiece support is moved along a workpiece feeding direction in order to avoid a desired mold provided in the workpiece processing part. It is provided so as to be slidable and fixed at an arbitrary position.

[0006]

According to the steel processing machine of the present invention, when processing is performed with a mold that does not interfere with the center gauge, the processing is performed by moving the center gauge forward in the workpiece feeding direction while positioning the center gauge in the workpiece feeding direction. . When processing is performed using a mold that interferes with the center gauge, the center gauge is slid and fixed in parallel with the workpiece feeding direction so as to avoid the mold unit. There is no need to remove the center gauge, and since the work can be guided in the immediate vicinity of the work processing portion, a short work can be accurately positioned, and a right angle can be easily formed in cutting.

The upper frame 7 has a ram 1 that presses a mold unit 9 on a turret table described later.
1 is provided movably up and down. A table 5 that can move back and forth with respect to the turret table is provided behind the turret table (front side), and an operation panel 13 is provided on a rear surface (front side) of the table 5.

On the right side of the table 5 in FIG. 11, there is provided a material feeding table 15 on which the work W is placed and fed. The feeder table 15 is configured such that a support frame 17 extending left and right continuously from the table 5 is supported by a support 19 so as to be movable back and forth.

On the left side of the table 5, a sizing table 21 is provided. The sizing table 21 has a channel-shaped sizing frame 23 extending in the left-right direction, and a plurality of columns 25 for supporting the sizing frame 23 movably back and forth. Similar to 17, it is integrally connected to the table 5. In addition, sizing table 21
Abutment plate 2 for positioning work W
7 is provided, and a DC servo motor 31 provided at the rear of the sizing device 29 is capable of moving and positioning in the left-right direction.

A plurality of transport rollers 33 for supporting the work W are rotatably provided on the support frame 17 and the fixed frame 23. Referring to FIG. 1 and FIG. 2 together, for example, a hydraulic cylinder 37 provided with a cylinder speed adjusting valve 35 is provided below the support frame 17 of the material feeding table 15, and the piston rod 39 is moved to the right. It is stretched in the direction.

At an intermediate position of the piston rod 39,
The lower ends of a plurality of (only one is shown in FIG. 2) rods 41 rotatably provided on the support frame 17 are connected. A V-groove roller 43 is rotatably provided at the upper end of the rod 41, and can reciprocate above the transport roller 33 by reciprocating the piston rod 39.

With the above-described configuration, the sizing device 29 is moved and positioned by the DC servo motor 31 and the left end of the work W is brought into contact with the abutting plate 27 to position the work W. At this time, the flat bar F
When a flat work W such as B is conveyed, the conveyance roller 33 is used, and a mountain-shaped work W such as an angle material is used.
Is transported, the piston rod 39 is moved rightward to position the V-groove roller 43 above the transport roller 33 to transport the angle material.

On the other hand, for example, a turret table 45 is provided rotatably and indexably as a work processing portion having a plurality of die units 9 for processing the work W in a radial manner, and an operation on the rear surface (front side) of the table 5 is performed. When the handle 47 provided on the board 13 is rotated, the table 5 serving as a work support can be moved back and forth integrally with the turret table 45 together with the support frame 17 and the fixed size frame 23.

Further, particularly when the diameter of the turret table 45 is large, the work W becomes unstable when machining a short work W. Therefore, the work W is not provided between the plurality of mold units 9 on the upper surface of the turret table 45. An auxiliary roller 49 that supports the work W from below when it is carried in is exchangeably and rotatably provided. If the auxiliary roller 49 is fixed to the turret table 45 as in the prior art, the auxiliary roller 49 does not match when the adjacent mold unit 9 is used, so the auxiliary roller 49 needs to be removed and it is troublesome.
It is rotatably supported on the turret table 45 to change its direction.

A pin hole (indicated by the same reference numeral 51 in the drawing) is provided on the turret table 45 at a predetermined position. After the auxiliary roller 49 is rotated in a desired direction, the pin 51 is rotatable. It can be fixed. In the case of processing an angle material, the V-shaped roller 5 as shown in FIG.
3 can be attached. The V-shaped roller 53 is provided with rollers 59, 59 rotatably mounted on an upper end portion of a Y-shaped frame 57 erected on a base plate 55, and the rollers 59, 59 rotate about rotating axes orthogonal to each other. Is to rotate. Thereby, the steel material can be stably supported.

Referring again to FIGS. 1 and 2, the support frame 17 is provided with guide projections 61 for positioning the work W in the front-rear direction when the work W is fed, and is provided with a table in the processing area. A center gauge 63 is provided on 5 corresponding to the guide projection 61, and forms a reference surface to which a workpiece W being fed or being processed is fitted. The center gauge 63 is a left center gauge 63F that guides the workpiece W on the left side of the machining area in the drawing.
And a right center gauge 63R for guiding the work W on the machining area and on the right side in the figure.

The left center gauge 63F is fixed to the table 5 as long as the mold unit 9 does not interfere when the turret table 45 moves rearward (downward in FIG. 1). The right center gauge 63R is on the table 5
It is slidably supported in the left-right direction (front-rear direction) in the figure along the gauge fixing member 65 provided above,
The range from the stopper 67 attached to the support frame 17 to the contact with the left center gauge 63F can be moved. Further, the right center gauge 63R is a pair of clamp levers 69, 69 provided on the gauge fixing member 65.
Can be fixed at any position.

With the above configuration, in the case of processing by the mold unit 9 which does not interfere with the center gauge 63, the right center gauge 63R is slid to the left side in the figure to make the protrusion 71 on the left end thereof. Front center gauge 63
F is fitted into the concave portion 72 at the right end. At the same time, the right center gauge 63R is fixed by the clamp levers 69,69.

In the case of machining with the mold unit 9 which interferes with the center gauge 63 during machining, the right center gauge 63R is separated from the left center gauge 63F to reach an arbitrary position corresponding to the selected mold unit 9. It is moved to the right side in the figure and is fixed by the clamp levers 69, 69 so as not to interfere with the mold unit 9.

With the above configuration, when processing the work W, the turret table 45 is first rotated to index a desired mold unit 9 into a processing area below the ram 11.
When the mold unit 9 of the type that comes into contact with the right center gauge 63R is selected,
Is moved to the right, and the handle 47 is operated to move the table 5 of the work support toward the turret table 45, that is, to the front, thereby positioning the table. At this time, the center gauge 63 is slid to the left to the immediate vicinity of the mold unit 9 and fixed by the clamp lever 69 so as to correspond to the shorter work W. Thereafter, the work W is positioned along the right center gauge 63R, and the die unit 9 is pressed by the ram 11 to perform processing.

As described above, since the center gauge 63 is freely slidable and freely fixed at an arbitrary position, the center gauge 63 can be easily moved to an area where the center gauge 63 does not interfere with the mold unit 9 and a short work W can be machined. In this case, the work W can be easily positioned by fixing the center gauge 63 in the vicinity of the mold unit 9, and the workpiece W can be cut accurately at right angles in the cutting process, thereby improving the processing accuracy. it can.

If an auxiliary roller 49 is provided between the plurality of mold units 9 on the turret table 45, it is possible to support even a shorter work W. Further, since the auxiliary roller 49 is rotatable, the auxiliary roller 49 can be aligned with the mold units 9 located on both sides of the auxiliary roller 49 in the material feeding direction. For this reason, it is not necessary to remove the auxiliary roller 49 even when using the adjacent mold unit 9, and the working efficiency is improved.

It should be noted that the present invention is not limited to the above embodiment, but can be implemented with appropriate modifications. That is, the left center gauge 63F and the right center gauge 6
If the 3Rs are both slidable and freely fixed at an arbitrary position, work guides immediately before and immediately after the mold unit 9 can be performed, and even a very short work W can be accurately machined, which is more effective. In this case, as shown in FIGS. 5 and 6, the left center gauge 63 </ b> F has a double structure in which the right end 73 in the figure is fixed to the left end 75 in the figure of the right center gauge 63 </ b> R. A hook 79 having a claw 77 at the tip on the right end side surface of the center gauge 63F is provided in a state urged by a spring 81 or the like, and the claw of the hook 79 is provided on a side surface of the left end portion 75 in the figure of the right center gauge 63R. You may make it provide the groove 83 with which 77 fits. Further, the left end of the left center gauge 63F may be tapered.

In the above embodiment, the auxiliary roller 4
9 was fixed with the pin 51, but instead may be as shown in FIG. 7 and FIG. That is, the auxiliary roller 49 uses a rotatable roller 89 rotatably supported on the upper end of a frame 87 erected on the base plate 85. A groove 91 (indicated by hatching in FIG. 7) corresponding to the mold unit 9 is provided on the upper surface of the turret table 45, and the base plate 85 of the auxiliary roller 49 is fitted into the groove 91 for positioning. It is.

Alternatively, as shown in FIG. 9, the auxiliary roller 49 is rotatable about a pin 93, and end blocks 95, 95 for determining the direction of the auxiliary roller 49 are provided. An abutment block 97 for determining the direction of the auxiliary roller 49 may be provided at the center.
In this case, the butting block 97 is
The auxiliary roller 49 is pressed by a spring 101 provided on a fixed block 99 fixed to the upper surface.

Further, as shown in FIG. 10, if the free bearing 103 is used instead of the auxiliary roller 49, it is not necessary to change the direction.

Furthermore, if the rotation axis of the auxiliary roller 49 is set parallel to the direction in which the work W is carried in, the work W can be easily moved in the front-rear direction.

[0029]

[Effect of the Invention] The steel material processing machine according to the present invention has the configuration as described above. When machining with a mold that interferes with the center gauge, the center gauge is parallel to the workpiece feeding direction. The mold unit is slid to such an extent that the mold unit is avoided and fixed at an appropriate position avoiding the mold unit.
