Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates to an improved drilling machine for metal sheet panels.

[0002]

2. Description of the Related Art As is well known, a drilling machine for a metal sheet panel generally has a work table for a panel to be drilled, a groove through which the work table passes, and a drilling head. It has a C-shaped or arch-shaped annular support structure and a moving means (manipulator) for holding a panel on a work table to be punched on one side thereof and moving it in harmony with a drilling head. .

In general, the panel must be perforated, for example, at equal intervals along all sides and very far from each other, so that the manipulator must be perforated in harmony with the perforation head. It must have an extended stroke so that it can be moved to all these places where it must be opened. Depending on the size of the panel, such strokes can be performed in a continuous process: gripping the panel, moving the panel a predetermined distance, releasing the panel, returning the manipulator to its original position,
Since the panel needs to be moved again when holding the panel again and performing the same operation as before, it can be made very large. Obviously, this makes the processing time very slow.

BRIEF DESCRIPTION OF THE DRAWINGS The features and advantages of the present invention will be more clearly shown by the following detailed description of some embodiments, given by way of non-limiting example in the accompanying drawings, in which: FIG.

Referring to FIGS. 1 to 7, these figures show a drilling machine according to a first embodiment of the present invention. Such a drilling machine comprises a worktable 1 and a support structure 2 for a panel to be drilled, the support structure 2 having an annular substantially closed arch shape as shown in FIGS. As shown, it can be formed from two substantially C-shaped or arched structures 2 ', 2 ". In both cases, the support structure 2 has a central groove 3 through which the worktable 1 passes.

Two substantially opposing drilling heads 4 ', 4 "
Are mounted inside the groove 3 of the support structure 2. Each drilling head comprises two overlapping hexahedral blocks 5,6. The former are known as perforated holder blocks and are fixed on top of the support structure 2 and are provided with one or more perforating tools. The latter is what is known as a matrix holder block, which is fixed below the support structure and is located below the worktable 1 and is provided with each matrix dies for drilling tools. I have. In the example shown, the two drilling heads are "multi-press"
Type. That is, in the drilling holder block 5, each drilling head is provided with a large number of drilling tools 7 (small tools) and 8 (large tools), and these tools have various sizes, and each has an actuator piston 9, Ten
Can operate independently of each other, and a large number of matrix dies 11
(For small tools) and 12 (for large tools) are provided. Drilling heads of this type are already known and are disclosed, for example, in U.S. Pat. No. 4,391,123. This head enables a number of drilling operations without having to substitute a drilling tool. As an alternative, the drilling heads can be of the "monopress" type, where in the drilling holder block each head is provided with a single actuator piston and each with a drilling matrix. A set of high-speed switching systems is provided or not provided. This is not essential for the purpose of the present invention.

Still referring to FIGS. 1 to 7, the drilling machine includes two manipulators 13 and 14, which are arranged at the two ends of the work table 1 so as to coincide with each other. Each of the manipulators 13 and 14 is indicated by a symbol Y in FIG.
A first carriage 15 movable along a slide guide 16 in a direction perpendicular to the support structure 2;
And a second carriage 17 movable along a direction parallel to the support structure 2 as shown in FIG. Pliers on carriage 17
Pinchers 18 are provided which enable the pliers to hold the metal sheet panel P with its edges corresponding to the carriage 17.

Referring to FIG. 2 to FIG. 4, the panel P1 for performing the boring process is automatically or automatically aligned with the manipulator 13 in the direction indicated by the reference symbol A in FIG. The same applies to the work table 1, while the manipulator 14 is provided with the drilling head 4 ′,
Engage with the previous panel P0, which has been transported for drilling equally by 4 ". Center positioning means 19 (for example pawls which project and retract with respect to the worktable 1).
After the center of the panel P1 is positioned with the assistance of the manipulator 13, the manipulator 13 holds one rear edge of the panel P1 with its pliers 18. Referring to FIG. 3, once the processing of the panel P0 is completed, the carriage 15 of the manipulator 14
, Whereby the working area in the support structure is cleaned, and the movement of the carriage 17 in either direction indicated by S in FIG. 3 releases the panel P0. At the same time, the carriage 15 of the manipulator 13 advances along the guide 16 in the Y direction, whereby the front edge of the panel P1 is introduced into the machining area in the groove of the support structure 2. The carriage 17 of the manipulator 13 moves in the X direction, while moving the panel P1 to various positions so that the drilling heads 4 ', 4 "can work at desired positions. The edge of the panel P1 Or, more generally, once machining of the first half is completed, manipulator 14 advances along guide 16 and grips the leading edge of panel P1 with pliers 18. Thereby, panel P1 is moved between the two manipulators. The manipulator 13 releases the panel P1, retreats along the guide 16, and returns to the position shown in FIG.
On the other hand, the manipulator 14 moves the panel P1 to various positions where it is necessary to machine the edge, or more generally the rear half. The manipulator 13 is ready to receive a new panel, whereby the processing cycle is repeated.

Due to the fact that two drilling heads, instead of a single drilling head such as the known drilling machines, are mounted on the support structure 2 at substantially predetermined intervals, the carriage 17 of the manipulator is moved. The path in the X direction that must be moved is significantly reduced. In particular, it is possible to avoid the movement of the panel in a very slow processing successive stage by the pliers of the manipulator gripping the panel, so that when the carriage 17 moves along the X direction and releases the panel, the carriage 17 returns to its initial position and again grabs the panel, whereby the movement is repeated. For example, with a stroke of 1500 mm along the X direction, the drilling machine can process a sheet with a length of 2500 to 2600 mm along the X direction without moving on a continuous stage. Become.

The two drilling heads 4 ', 4 "can be fixed to the arch 2. The arch 2 has a drilling head.
4 ', 4 "can also be provided at a number of fixed positions, so that the spacing between the heads can be varied during assembly of the device. Alternatively, as shown schematically in FIG. In order to adjust the distance between the two heads (or one of them) according to the size of the panel to be perforated, the slider 50, the guide 51 and, for example, With screw 52, X
It can also be mounted in a sliding path along the direction.

FIG. 7 shows a modification of the above-described punching machine.
Here, the support structure 2 is not in the form of a closed arch, but is formed of two arches 2 ', 2 ". The two arches 2', 2" have two drilling heads 4 ', 2'. It can also be made movable, preferably with respect to the base 100 of the drilling machine, so that the distance between the 4 "is adjustable.

FIGS. 8 to 10 show a punch according to a second embodiment of the present invention. Unlike the previously described embodiment, this drilling machine has a single manipulator 13,
A rotating body 60 for rotating a panel to be processed is provided. In fact, the single manipulator 13 cannot be machined without the rotating body 60 in correspondence with the edge of the panel that engages the pliers 18. The rotator 60 makes it possible to once complete all the boring operations on the free end side of the panel, and it is also possible to perform boring operations on the other end side of the panel. FIG. 9 shows a rotation operation of the panel P by the rotating body 60.
