Abstract

PURPOSE:To improve rigidity of frame thus to improve linearity of cutting line of plate to be cut by constructing such that scrap is discharged by a scrap discharger provided at the side of cutter through open section at the side of cutter. CONSTITUTION:A raser beam welder is provided with a cutter 20 and a scrap discharger 21. Then scraps 15, 16 are cut in a lower cutter 11 and in order to discharge scrap through a cutter 20, the discharger 21 is moved to the position shown by dashed line E to lift the scrap lifter while mounting scraps 15, 16 to the position below the dashed line E and to insert scrap into the discharger 21. When returning the discharger 21 to the original position, scrap is scratched from above the lifter then moved in the direction perpendicular with the cutting line and discharged onto a shooter. Consequently rigidity of frame is improved to improve linearity of cutting.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cutting machine built into a welding machine or the like that requires precision using a laser beam or the like, and particularly relates to the arrangement of a scrap discharge device in the cutting machine.

To explain the structure of a conventional laser beam welding machine, the laser beam is transmitted to the head 3, the processing spatula P3 focuses the laser beam, and irradiates the weld line with the laser beam.

Welded plates clamped by fixed crank bag and moving crank A1/3. /4' is its end /3. /A (Scrap below /S.

/A) are cut at the same time by the double-cut cutting machine t, and scrap /! , /A is a scrap discharging device 7 combined with the cutting machine B, and the scrap is placed on the container Y9 by the chute g located under the extension of the cutting line. The cutting machine 6 has an upper blade 10 and a lower blade //, and the cutting machine frame supporting these has an outlet /7 for discharging scraps.

In the conventional welding machine configured in this way, the plate to be welded /3
, /'I, as shown in FIG. and the plate to be welded/3. /ll and moved the cutting machine 6 to the position shown by dotted line A in FIG. 2, then lowered the upper blade 10 and cut the plate to be welded /3.
The ends of /4( are cut along the lines /g and /9 in Figure 7. The cut scraps /A- and /A are marked along the dotted line i s' in Figure 3.
, it is cut off into the lower blade as shown by '.

Return the cutting machine 6 to its original position as shown in Fig. 2, move the moving clamp in the direction of arrow B (Fig. 1), and cut the cutting line 19 of the plate to be welded 1 to the cutting line of the plate to be welded /3. /g. Next, a laser beam is emitted from the laser processing head r3, and the laser processing head r3 is directed in the direction of the arrow C to the plate to be welded/
Run on the butt line (same as the cutting line/g) of 3°/g. The laser beam is applied to the plates to be welded which are butted together at the butt line/3. /'Weld I. At the same time, when the cutting machine B returns to its original position, the scrap discharging device 7 moves forward once to the position indicated by the dotted line and then returns to its original position, as shown in Fig. 2, thereby discharging the scrap as shown by the lower blade //. be done. The scrap passes over the chute g and is conveyed onto the conveyor q (Fig. 1).

In the conventional welding machine configured and operated as described above,
In that cutting machine, a discharge port /7 for moving the scrap discharge device and scrap discharge was provided in the frame /J as shown in Fig. 3. Therefore, the mechanical strength of the frame /2 was reduced, and the laser Cutting line/g required by beam welding machine, etc.

There was a drawback that the linearity was /9.

(,?) Moreover, since the clamper, cutter, cutting machine, and scrap discharge device 7 are arranged in a straight line, there is also a drawback that the efficiency of the installation area is poor.

This invention was made in view of the above-mentioned drawbacks of conventional machines.It eliminates the drawbacks of the cutting machines built into conventional laser beam welding machines, etc., and has a frame with high rigidity. The aim is to provide a good and compact cutting machine.

In order to achieve the above objectives, the cutting machine according to the present invention has the following features:
The present invention is characterized in that the scrap discharge device is installed at a position retreated from the workpiece conveyance line of the cutting machine so as to discharge scrap from the cutting machine in a direction perpendicular to the cutting line of the cutting machine.

The present invention will be specifically described below with reference to the illustrated embodiments.

As shown in FIGS. D and 5, in one embodiment of the present invention, the laser beam welding machine has the same configuration and arrangement as the conventional machine shown in FIGS. , equivalent members are given the same reference numerals, so their explanation will be omitted. The cutting machine 20 has a scrap discharging device 21 in the lateral direction, unlike the one shown in FIG. located to discharge scrap in a direction perpendicular to the

Therefore, as shown in FIG.
1I is also installed below the scrap discharging device 2/ next to the frame of the cutting machine 20 and 22, and the conveyor 2 on the left is also arranged parallel to the cutting line of the cutting machine with an interval as shown in FIG. ing.

The laser beam welding machine with the built-in cutting machine configured as described above is exactly the same as the conventional machine, and the welding plate/3. /'I is cut and the drawing board is welded at the welding line, but the scrap /
The discharge mode of A; and /A is different. The cut scrap /Ar, /l is cut into the lower blade //, and the cutting machine 2
It remains the same until 0 returns to its original position from the cutting position, but
To discharge scrap, use a scrap discharge device: l/
Move the scrap lifter 23 (Fig. 3) to the position shown by the dashed line E in Fig. 3 and scrap/! .

(g) With /6 on it, raise it to the position below the dotted line and place the scrap on the dotted line / ! i', /b' into the scrap discharging device λ/. Next, when the scrap discharging device is returned to its original position as shown in the figure, the scrap is scraped off from above the scrap lifter 23, moved in a direction perpendicular to the cutting line of the cutting machine, and moved to the chute, 2 hiro ( (Fig. S), slides on the chute 21I, is placed on the conveyor S, and is conveyed.

As described above, according to the present invention, scrap is removed from the cutting machine by a scrap discharge device installed next to the cutting machine.
Since the scrap is discharged from the side opening (opening necessary for cutting the board), there is no need to make a hole in the frame 22 of the cutting machine 20 like the scrap outlet 17 of the frame/2. Therefore, the rigidity of the frame is improved, and the plate to be welded/l.

The linearity of the cutting lines /l and /9 is improved. Also the 7th
As shown in the figure, for the clamper + 1 and the cutting machine 20,
Since the scrap discharge device 21 is located on the side and is arranged in an L-shape, the efficiency of the installation area of the welding machine is improved and the welding machine can be made compact.
