The present invention is an angle V-groove cutter for making a predetermined groove on one side of the angle to bend at an angle to bend the L-shaped angle to 90 ° (or a predetermined angle), in particular, using the high pressure of the hydraulic cylinder It is designed to transfer the V-shaped cutting degree.

In order to bend the L-shaped angle at a predetermined angle, first, as shown in FIG. 1 (a), a predetermined V groove (H) must be provided on one side of the angle (A).

To this end, the conventional work was performed at least twice by using a hacksaw, a cutting grindstone or an oxygen melting torch according to the thickness thereof, and thus a long work time was required. Many manpower consumption, as well as tired workers, was a factor in the work efficiency.

The present invention devised to solve such a problem is to provide an angle V-groove cutter configured to cut the angle as if cut out with scissors by attaching the V-shaped cutting angle to the ram end slowly advancing into the hydraulic cylinder. It is meant to improve efficiency.

When described in detail with respect to the configuration and operation based on the accompanying drawings as follows.

As shown in FIG. 2, the cutter according to the present invention inserts a large weight ram 3 into the transfer guider 2 at the center of the upper surface of the table 1 so as to be slidably movable so that the platen 4 at the rear thereof may move forward and backward. The piston rods 5 'and 6' of the hydraulic cylinders 5 and 6 are disposed adjacent to the end surfaces of the rods 5 'and 6' in opposite directions, and the front face of the ram 3 has a V-shaped cutaway ( (7) attaches the V-shaped support (9) with a seat (8) in front of it, and attaches two single-stroke hydraulic cylinders (5) (6). Hydraulic pumps and hydraulic switching valves (not shown) are used for operation.

In order to give out the V groove (H) to the angle (A) by the present invention cutter as described above, the angle (A) of material on the seat (8) provided by the upper surface of the table (1) and the blade support (9) in front of the ram (3) ) And place the hydraulic pump (not shown).

That is, when the piston rod 5 'of the hydraulic cylinder 5 moves as shown in FIG. 3, the ram 3 moves forward together with the platen 4 adjacent to the end face of the piston rod 5' (indicated by "→"). Done.

Then, V-shaped cutout (7) attached obliquely to the tip of the ram (3) proceeds through the blade support (9), with its pointed portion first reaching the lower portion of the vertical inner surface of the angle (A), so it is angled like a cut out with scissors. The vertical one side of (A) is cut out, and a predetermined V groove (H) is cut out.

At this time, since the vertical outer surface of the angle (A) is supported on the front of the blade support (9) is to work safely without flow.

To return the ram 3 after the cutting operation is completed, operate the hydraulic switching valve (not shown) to shut off the hydraulic pressure of the hydraulic cylinder 5 and at the same time apply hydraulic pressure to the reverse hydraulic cylinder 6, the piston As the rod 6 'is advanced backward (indicated by "←"), the ram 3 is retracted together with the pressure plate 4, and the piston rod 6' of the hydraulic cylinder 6 is also manually returned.

By repeating the above operation, the V groove cutting operation of the angle can be performed.

For reference, the application of two single stroke hydraulic cylinders (5) and (6) to the angled V-groove cutter of the present invention effectively performs the forward and backward movement of the ram (3), which is a large weight object, and easily separates these hydraulic cylinders from the main body. The intention is to make it available to other devices.

Of course, only one reciprocating cylinder with a hydraulic port in two positions is possible.

As described above, according to the present invention, the V groove cutting operation of the angle can be performed by only one mechanical operation, so it can be performed within a short time (about 8 seconds), and the cutting surface is clean because it proceeds as if the V groove cutting is cut out. It does not require reworking of the cutting surface, and it is a very effective design that can contribute to the maximization of work efficiency because it can reduce the fatigue of man and worker.

Claims (1)

A large heavy ram 3 is slidably inserted into the transfer guide 2 at the center of the upper surface of the table 1 so that the platen 4 at the rear thereof moves the piston rod of the hydraulic cylinders 5 and 6 for forward and backward movements. 5 ') (6') sections adjacent to each other in opposite directions, and V-shaped cutaways 7 are attached to the front of the ram 3, while a seat 8 is placed on the front. Angle V groove cutter, characterized in that the V-shaped support (9) is fixed.
