SU393054A1 - INSTALLATION FOR PACKET CUTTING OF SHEET - Google Patents

Description

one

The invention can be used for gas cutting parts, such as elliptical bottoms, from a sheet.

Installations for the package cutting of sheet parts are known, comprising a table for parts fastened on the frame and a portal moving along the table with a cylinder mounted thereon, on which the clamping plate is fixed, as well as a carriage with a cutter.

However, these installations are not productive enough.

In order to improve the performance in the proposed installation, the pressure plate is made in the form of a replaceable copier, the paired guides of which are movably mounted with a carriage with a cutter.

FIG. 1 shows the proposed installation, the general view; in fig. 2 - the same, top view; in fig. 3 - the same, side view.

The installation comprises a frame 1 with a table 2 and stops 3 on which self-propelled trolleys 4 are located, a portal 5 with a pneumatic device 6 mounted on it, in the lower part of which a clamping plate 7 is fastened to the stem, made in the form of a replaceable copier. On the rails 8 of the latter, the self-propelled carriage 9 is mounted for movement with a cutting torch 10 for gas cutting. In the lower part of the trolley 4 of the gantry 5, the stops 11 are fixed with clamps 12 entering the grooves 13 of the base 14, fixed on the frame /. On the trolleys of the portal, the grippers 15 are also strengthened, covering the rail heads 16.

The installation works as follows.

The sheet elements of the package are laid on table 2 and are sent to the stops 3, after which the drives of the trolleys 4 of the port 5 are turned on and the clips 12 automatically turn on. When the portal 5 moves along the rails 16, the stops 12 stops enter the cutting position 13 of the shoes 14, the portal is stopped, and the latches 12 are turned off.

Then pneumatic device 6 is turned on, on the brush of which the replaceable clamping plate 7 is fixed, and in the cutting zone the package is compressed. After this, the drive of the self-propelled carriage 9 with the cutter 10, and the carriage 9

begins to move on the guide 8 around the perimeter of the clamping plate, which also serves as a rider.

The carriage 9 automatically stops, the pneumatic device 6 is turned on to rise, and

presser plate 7 is raised.

Then, at the same time as the portal is turned on, the latches 12 are automatically turned on, which extend from the slots 13 of the bashmaks 14. The portal moves to the next position

the cycle is repeated to the last position.

Preventing the separation of the portal 5 from the rails 16 when the stack sheets are pressed by the pneumatic device is carried out by the grippers 15, which cover the rail head 16 with a gap and freely move along the rail head as the portal moves.

Subject invention

An arrangement for batch cutting of sheet metal parts containing reinforced on the frame

a table for parts and a portal moving along the table with a cylinder mounted on it, a plate attached to the stem of the clamp, and a carriage with a cutter, characterized in that, in order to increase productivity, the pressing plate is designed as a replaceable copier, on the guides of which movably mounted carriage with a cutter.
