[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a section steel processing machine, and more particularly, to easily move a rear end of a long section steel to a position corresponding to a main body vise provided close to a processing section. The present invention relates to a section steel processing machine having a configuration capable of being transported.

[0002]

2. Description of the Related Art Conventionally, a long work is carried into a processing machine by moving a gripper holding the work.

[0003]

[Problems to be Solved by the Invention] When shuttle feed is performed by gripping the upper part of a flange of an H-section steel or the like with a gripper, a single feed length becomes longer, and positioning accuracy becomes higher. When entering a region that interferes with the vice that is being gripped, it is necessary to avoid the vise.
As a result, extra time is required for gripping, and a mechanism for avoiding the vise is required, which may increase the cost of the processing machine and complicate the structure.

Further, when feeding by gripping the rear end of an H-beam or the like by means of a gripper, it is necessary to provide a feed length corresponding to the length of a long work, although the gripper is hardly changed. Therefore, when the apparatus is enlarged, and when the rear end portion of the H-section steel or the like is transported to a position corresponding to the vise, the vise and the gripper interfere with each other, so that further transport is impossible.

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention provides a main body vice capable of gripping a shaped steel at a position close to a processed portion for processing the shaped steel. The carriage provided movably along the roller conveyor supporting the section steel to be conveyed to the carriage is provided with a clamp arm extending in the longitudinal direction of the roller conveyor, and the tip section of the clamp arm can grip the section steel. In the section steel working machine provided with the work clamper of the above, a notch into which the work clamper can enter is provided in the fixed vice jaw provided in the main body vise, and the end of the section steel is clamped by the work clamper to perform the cutting. The end portion of the section steel can be conveyed to the machined portion through the notch.

For example, a main body vise 9 is provided on the near side (left side in the drawing) of the processing portion 7 for performing the drilling process in the X-axis direction, and a front vise 11 is provided on the other side (right side in the drawing) of the processing portion 7. .

At a side position of the roller conveyor 5, a guide table 13 extending in parallel is provided. Referring to FIG. 2, a guide rail 15 and a rack 25 are provided on the upper surface of the guide table 13, and a guide plate 18 is fixed to the upper surface of the rack 25. Since the guide roller 19 sandwiching the guide plate 18 from above and below is installed on the carriage 17 side, the carriage 17 is guided by the guide rail 15 and the guide plate 18 and supported on the guide table 13 so as to be reciprocally movable. I have.

In order to reciprocate the carriage 17 along the guide rail 15, the carriage 17 is provided with a traveling motor 23 having a pinion 21 mounted at the lower end of a rotating shaft. An encoder (not shown) is provided. The pinion 21 is a rack 25
It is provided so as to mesh with. Accordingly, by appropriately controlling and driving the traveling motor 23, the carriage 17

With the above construction, the vertical slider 31 can be moved up and down and positioned along the guide member 27 by appropriately operating the vertical movement cylinder 35.

The upper and lower sliders 31 each have a work clamper 3 for gripping a flange of the work W at the tip.
7 is provided so as to be swingable via a spherical bearing 41 and has a rear end (FIGS. 1 and 4).
Since the upper surface is kept substantially horizontal by contacting the upper surface with the pressing pin 43, it is possible to follow up / down, left / right vibrations and shakes during material conveyance. The work clamper 37 has a fixed clamp jaw 45 provided at a tip of a clamp arm 39 and a movable clamp jaw 49 supported by a hinge pin 47 so as to be rotatable in the horizontal direction with respect to the fixed clamp jaw 45. .

Each of the fixed clamp jaw 45 and the movable clamp jaw 49 has a shape having a purpose. That is, the fixed clamp jaw 45 has a vertically low shape so as to sandwich the interference region with the fixed vise, and the movable clamp jaw 49 has a narrow width so as to be inserted into a narrow work. The distal ends have grippers 51 and 53, respectively. In addition, a photoelectric sensor 55 is provided near the distal ends of the fixed clamp jaw 45 and the movable clamp jaw 49 so that the workpiece W can be clamped while detecting the workpiece W when clamping.

A cylinder 57 for rotating the movable clamp jaw 49 is provided on the rear side of the hinge pin 47 of the fixed clamp jaw 45 (see FIGS. 3 and 4). A spring 59 is provided for pulling the rear end of the movable clamp jaw 49 toward the fixed clamp jaw 45, and is attached to the movable clamp jaw 49 in such a direction that the distal end (right end in the figure) is always separated from the fixed clamp jaw 45. I'm going.

Accordingly, by injecting air or pressure oil into the first cylinder chamber 57A, the piston rod 57R is lowered in FIG. 4 and the movable clamp jaw 49 is rotated in the direction A in FIG. I do. Further, air or the like is injected into the second cylinder chamber 57B to raise the piston rod 57R in FIG. 4, and the movable clamp jaw 49 is rotated in the direction B in the drawing by the restoring force of the spring 59 to unclamp.

FIG. 5 shows a fixed vice jaw 61 in the main body vise 9 and a fixed vice jaw 63 in the front vise 11. FIG. 6 shows a fixed vice jaw 61 and a movable vice jaw 65 of the main body vise 9. In the main body vise 9, a movable bed 69 is moved toward and away from a fixed vice jaw 61 attached to a fixed bed 67 fixed to the main body of the shaped steel working machine 1 by a hydraulic cylinder or the like (not shown), whereby a fixed vise is provided. The work W is clamped or unclamped by the cooperation of the jaws 61 and the movable vice jaws 65 provided on the movable bed 69.

Notches 73L and 73R for rollers 71 for supporting the work W from below are provided at positions corresponding to the lower part of the work W on the surfaces facing the fixed vice jaw 61 and the movable vice jaw 65, respectively. ing. The notch 73R on the right side in the figure is formed to be larger than the notch 73L on the left side, so that the fixed clamp jaw 45 can enter the inside of the main body vise 9 with the lower end of the work W clamped, and the notch 73R , The workpiece W can be fed. The fixed vice jaws 61 grip the workpiece W with a clamp surface as wide as possible, and do not interfere with the fixed clamp jaws 61.

Next, with reference to FIGS. 1 and 7, the operation of transporting the work W (here, an H-section steel will be described as an example) will be described. The H-section steel W placed on the roller conveyor 5 with the flange WF standing in the vertical direction is machined into the processing section 7.
First, the clamp arm 39 is positioned above the H-shaped steel W by moving the vertical slider 31 up and down, and the carriage 17 is moved backward in the X-axis.

The photoelectric sensor 5 provided on the work clamper 37
5, the H-shaped steel W is detected, the upper end of the flange WF of the H-shaped steel W is clamped by a grip 53 provided on the lower surface of the tip of the work clamper 37, and the position in the X-axis direction is determined by an encoder (not shown). The traveling motor 23 is operated while detecting, and the carriage 17 is moved forward.

Subsequently, when the H-section steel W is long, the work clamper 37 is unclamped and raised, moved in the X-axis rearward direction, and then again clamped to the X-axis frontward direction. To move forward. By repeating this, a so-called shuttle feed is performed. When the upper end is clamped, the H-shaped steel W can be carried in only before the main body vise 9.

When the remaining length of the work is within the feed range of the carriage 17, the H-shaped steel W is once grasped by the main body vise 9, the work clamper 37 is unclamped, and the carriage 17 is moved rearward of the H-shaped steel W. The work clamper 37 is lowered to a predetermined position (the height position of the notch 73R provided on the fixed vice jaw 61) by lowering the upper and lower slider 31. Then, the carriage 17 is advanced again, the H-shaped steel W is detected by the photoelectric sensor 55, and then the gripper 5 provided at the tip of the work clamper 37 is moved.
1 clamps the tail end of the H-section steel W.

Then, the main body vise 9 is unclamped and the carriage 17 is moved to feed the H-shaped steel W. If the upper end is grasped in this section, the work clamper 37 interferes with the main body vise 9, but the fixed vice jaw 61 of the main body vise 9 is provided with a notch 73R, and the work clamper 37 enters the notch 73R. Interference can be avoided.

As described above, the shuttle feed can be lengthened by clamping the upper end of the H-shaped steel W up to the front of the main body vise 9. As a result, the number of times of grip change can be reduced, so that the material feeding length can be made accurate and the working time can be shortened.

When the tail end of the work is gripped, the fixed vice jaw 61 of the main body vise 9 is provided with a notch 73R so as not to interfere with the work clamper 37.
Interference between the work clamper 37 and the fixed vice jaw 61 can be avoided. For this reason, the carriage 17 can be moved to the vicinity of the processing section 7 while the rear end of the H-section steel W is clamped, and the rear end of the section steel W can be positioned with respect to the processing section 7. Also, you can send the material
Since the processed H-section steel W can be carried out to the front vise 11, the H-section steel W can be positioned in the processing section 7 over a range from the front end to the rear end of the section steel, and the processing becomes easy.

Further, since the work clamper 37 is provided with the photoelectric sensor 55, when the H-section steel W is clamped, it can be clamped accurately without colliding with and damaging the H-section steel W. . Further, the same photoelectric sensor 55 can be used when clamping the upper end of the H-section steel W and when clamping the rear end of the H-section steel W,
Cost reduction can be achieved.

The grippers 51 and 53 are provided at the distal end and the lower surface of the distal end of the work clamper 37, respectively, and are located below the lower surface of the clamp arm. Without H-section steel W
Can be gripped at the top and rear ends of the.

It should be noted that the present invention is not limited to the above-described embodiment, but can be implemented with appropriate modifications. In the above embodiment, the feeding of the H-shaped steel W, which is a long material, has been described.
If the rear end portion of the H-section steel W is gripped by using No. 7, there is no change in gripping, which is more effective.
