SU1402425A1 - Arrangement for guiding and pressing short-size blanks - Google Patents

Abstract

The invention relates to wood. The purpose of the invention is the elimination of overturning and ejection of blanks at the beginning of processing. Clamping and guiding plates 6 mounted on levers 7 and 8 are installed in housing 5. Lever 8 is connected to spring 9. Clamping plate 6, with its pointed ledge, enters the groove of the chip breaker 12. and with their pointed ledges they press the workpiece against the working plane of the table at the beginning of processing. The shoulder and chip breaker 12 contact on two lines, creating a total clamping force to the working plane. For reliable contact with the workpiece and prevention of its release, it is necessary that its height is not less than the height of the step. 4 pe. kn Fig. /

Description

FIELD: woodworking industry. gi, and more specifically to the production of musical instruments in, in the manufacture of blanks of wood of hardwood with the smallest length (about 100 mm), which can be used for details of the mechanics of the piano with the corresponding processing on reysmusovyh machines.

The aim of the invention is to prevent tipping and ejection of blanks at the beginning of processing.

Figure 1 shows the device section; in FIG. 2, the same; with the workpiece in the feed zone in FIG. 3, the same, with the workpiece in the zone of the start of processing in FIG. 4, section A-A in FIG.

On the work table 1 with the lodging lugs 2, workpieces 3 are laid. Above the working plane 4 of the table 1 there is a housing 5, in which pressure plates and guide plates 6 are mounted, fixed on levers 7 and 8. Lever 8 is connected to spring 9. Pressure clamp the plate 6 with its pointed ledge 10 enters the chipmaker 12 in the groove 11. In the feeding zone, the workpiece 3 contacts on one side with the working plane 4 of the table 1 and on the other with the surface 13 of the plate 6. In the zone of start of processing, the workpiece 3 contacts as with the surface 13 of the plate 6, so with a pointed ledge 10 and chip breaker 12.

The device works as follows.

The workpiece 3 is moved along the working plane 4 by the stops 2, while the plates 6 are raised and the entire surface 13 fits the workpiece to the work plane 4. The pressing force is created and adjusted by the springs 9 and the levers 7 and 8. The plates 6 left on each side create a continuous pressure

The rotation of the workpiece 3 and prevent its lateral displacement.

In the treatment start zone, the pressure plates 6 are raised by the amount of the pointed step 10, and the work force is affected by pressure forces distributed along a line perpendicular to the direction of movement from the step 10 and the chip breaker 12. For reliable contact of the stop with the workpiece and preventing its release, it is necessary its height was not less than the height of the ledge, i.e. h, where h is the height of the stop, h, is the height of the ledge.

In a device with pressure plates having steps, which enter into the grooves of the chipbreaker and are displaced relative to it in the zone of contact with the workpiece, sufficient forces are created to prevent it from tilting.

The invention will allow the use of solid wood wastes for the manufacture of piano mechanics and consumer goods.
