(54) MACHINE FOR HANDLING DETAILS ON CIRCUIT

one

The invention is related to the woodworking industry and can be used in machines for processing bent-glued parts along the contour.

A machine for machining parts along a contour containing a frame on which a turntable with a reversible mechanism is installed is equipped with a removable cradle, whose working surface is identical to the surface of the workpieces, cutting tools that can be moved relative to the workpieces, and installed between the cutting tools above the cradle , moreover, the working surface of the clamp is made identical to the surface of the workpieces 1.

The known machine has low productivity due to the slow rotation of the table by the worm gear and the need to change the copier when the contour is changed. The purpose of the invention is to increase the productivity of the machine.

The goal is achieved by the fact that the machine is equipped with a feed mechanism made in

the form of a movable carriage on which a table is installed, the table turning mechanism being designed as a pneumatic cylinder mounted on a carriage and pivotally connected to the table, while the mechanism of pressing the workpieces is also mounted on the carriage.

FIG. 1 shows a machine, a general view; see 2 shows section A-A in FIG. one.

On the base 1 on the guides 2 by means of the rollers 3 there is a feed mechanism, made in the form of a mobile carriage 4, on which table 5 with a removable cradle 6 is located with the possibility of turning about a vertical axis, whose working (top) surface

j is made identical to the profile of the package of blanks 7. On the carriage 4 there is a device for turning the table 5, made in the form of a pneumatic cylinder 8 and connected with a hinge 9 with a table 5. On opposite sides of the cradle 6 are disk

Claims (1)

20 saws 10 set in rotation by autonomous electric motors 11. Above the cradle 6 Between the saws 10 a clamping mechanism is installed, made in the form of a pneumatic cylinder 12 with clamps 13, which are connected to the rod of a pneumatic cylinder 12 by means of a hinge 14. 15. The clamping mechanism with the help of the bracket 16 is fixed on the carriage 4. To the lower part of the carriage 4, the bracket 17 is fixed, having a slot 18, 6 of which is movably hindered, a finger 19, attached to the sprocket 20, which is connected with a chain 21 gears 22 with gear The driver 23, the latter is connected with the V-belt transmission 24 with the electric motor 25. On the guides 26, which are fixed on the sides of the frame 1, frames 27 are installed with screws 28, stops 29, pneumatic cylinders 30 and guides 31 on which the plates 32 are mounted with fixed on these are electric motors ii. The machine works as follows. On the lodgement 6 table 5 stack package blanks 7. Pneumatic cylinder 12 through the hinge 14 and the clamps 13 is fixed on the lodgement 6 package blanks. The basis for fixing the package of blanks 7 is the corresponding configuration of the lodgement -6 and blanks 7. When the motor 25 is turned on, torque is transmitted to the finger 19 by means of a V-belt Transmission 24, gear 23, chain transmission 22 and sprocket 20. In this case, the finger 19 located in the slot 18 of the bracket 17, moves the carriage 4 to the zone of saws 10. Simultaneously with turning on the electric motor 25, the electric motors I are also included, on which shafts 10 are mounted. The blanks 7 fixed on the cradle 6, the table 5 and the carriage 4 move to her back position. In this case, the workpiece 7 sawdust-. on both sides. After the carriage 4 leaves the working zone of saws 10, the pneumatic cylinder 8 is turned on, which, by means of a hinge 9, rotates the table 5 with the cradle 6 and the package of blanks 7 by 90 ° through the hinge. At the same time as the pneumatic cylinder 8 is turned on, the pneumatic cylinders 30, which follow the guide 31 t electric motors; Do not saw 10 until the re-adjustable stops 29. When the carriage 4 moves to the initial position, the blanks 7 are sawn from the other two sides. After the carriage 4 returns to its original position, the pneumatic cylinders 30 of the plate 32 with the electric motors fixed to them 11 Saws 10 return to the initial position, the pneumatic cylinder 8 Rotates the table 5 with the cradle 6 and the blanks 7 fixed on it, to the initial position, the pressure from the pneumatic cylinder 12 is released and the spring 15, the clamp 13 rises, freeing the sawing of the workpiece 7, after which they are removed from the lodgement. With screws 28 install-. The saws are positioned and fixed to a predetermined sawing size of the workpieces 7. The machine is controlled by means of automation (not shown). In addition, the machine can operate in semi-automatic and manual modes. Claims A machine for machining parts along a contour that contains a frame on which a rotating table with a removable cradle is installed, which has a removable cradle, whose working surface is identical to the surface of the workpieces, mounted for moving relative to the workpieces, cutting tools and the workpiece pressing mechanism, mounted between cutting tools above the cradle , and the pressing surface is made identical to the surface of the workpieces, which is different in that, in order to increase production The machine is equipped with a feed mechanism made in the form of a pneumatic cylinder mounted on a carriage and pivotally connected by a table, while the mechanism for clamping the workpieces is also fixed on the carriage.
