MACHINE FOR CUTTING ALUMINUM PROFILES FOR FRAMES AND SIMILAR ITEMS

Abstract

The present invention relates to a machine which allows to automatically cut aluminum profiles for frames, with lengths and angles corresponding to the dimensions of the window or door opening, previously set on the control panel. the advantages of having a considerably reduced overall dimensions and of allowing a more complete use of the sections, with a consequent reduction of waste, are described. For this purpose, the profile, instead of being pushed from behind, is gripped in the front part by a pliers, which does not protrude and does not interfere with any machining at the end of the piece.

Description

DESCRIPTION of the finding entitled: "Machine suitable for cutting aluminium profiles for window frames and similar", of the firm "LGF di Musson! Walter & CSnc", of Italian nationality, with registered office in Verucchio (FO), loc. Villa Verucchio, via Togliatti N.81, represented by its partner Mr. Grandi Francesco, through the agent Eng. Stefano Maschio, via Milite Ignoto N.44, Pesaro, registered in the Register under No. 53. The invention in question concerns a machine that allows the automatic cutting of aluminium profiles for window frames, with lengths and angles corresponding to the dimensions of the window or door opening, previously set on the control panel. The ever-increasing popularity of aluminum window frames has led to the development of electronically controlled machines capable of automatically making perpendicular or angled cuts on the profile being processed. They are essentially made up of a bench with workpiece support surface and pressure devices from a cutting head for its blocking and TEST OFFICE! | TRADE IN PESAR > THE OFFICIAL INDUSTRY CIANATO ÌBINO iANTE Tiltable. The profile is usually fed manually. Other, more automated machines are equipped with a sliding arm, fitted with a gripper that pushes the profile from the rear end. Given the considerable initial length of the profile, the arm with the gripper extends significantly beyond the bed, increasing the overall footprint of the machine. Another drawback is the inability to cut the end of the profile gripped by the gripper: sometimes, by just a few centimeters, the last segment of profile, which would otherwise be sufficiently long, cannot be used. The present invention overcomes these drawbacks. Compared to other machines of the same type, the one described offers the advantages of mechanically moving the profile, having a significantly smaller footprint, and allowing for more complete automatic use of the profiles, resulting in reduced processing times and waste. For this purpose the profile, instead of being pushed from behind, he is grabbed in the part Dr. Inor^SWANO MALE front by a gripper, which does not protrude from the machine bed and does not prevent any cutting of the terminal end of the piece. The invention is now described in detail, with reference to the attached drawing, which illustrates by way of example only one of its possible implementations. Fig. 1 shows a schematic side view of the machine. Fig.2 represents the machine seen frontally, from the entry side of the profile. Fig. 3 represents a top view. In these figures, 1 indicates the work surface, equipped with a series of rollers 2. 3, fig. 1, indicates a segment of profile already cut. 4 indicates the cutting head, which can be tilted, as shown in the dotted line in fig. 1, to make angled cuts. 5 indicates the slot for the blade to pass through. Profile 3 is taken in the front part 0 by the pneumatic gripper 6 and then dragged until the pre-established cutting point is in line with the blade. The profile is then Dolt. IDEANO JMSCH10 blocked by the pneumatic pressers 7, as shown in fig.2. The gripper 6 can translate longitudinally by virtue of the slide 8, which can slide on the guide 9, to impart the feed movement to the profile. The clamp can also be adjusted vertically and transversely, to position it according to the shape and dimensions of the profile. The vertical adjustment movement is obtained by means of the slide 10, sliding on the guide 11 of fig. 3; it is applied by means of the screw knob 12. The transverse adjustment movement is obtained by means of the slide 13, fig. 1, sliding on the guide 14; it is applied by means of the screw knob 15. The sequence of feed and cutting movements is automatically controlled by an electronic circuit, on which the dimensions of the door or window opening are previously set. Obviously the non-essential construction details may be different from those illustrated in by way of example only, without limitation to go beyond the scope of this invention. Pesaro, 08 / 03 / 94.
