Description

The invention relates to machines for the treatment of predominantly wooden fittings such as bodies of revolution and can be used in the forestry, woodworking and local industries for the manufacture of parts for board games, for example, Lotto parts.

The purpose of the invention is to simplify the design and increase productivity by eliminating manual labor.

FIG. 1 shows a machine, a general view; in fig. 2 - the same plan view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 2

The machine for processing shaped articles consists of a bed 1, on the upper part of which there are mounted guides 2 in which the plate 3 is movably mounted.

On the plate 3, parallel to each other, cutting mechanisms 4 are installed, each of which is made in the form of a rotational mechanism coaxially arranged, and a mechanism for clamping workpieces made in the form of a horizontal rod 5, which is spring-loaded with a spring 6 and mounted movably relative to the frame 1 in the support 7.

The rod 5 is made at one end of the hollow, where the spindle 8 is mounted on bearings 9. At the other end, the rod 5 is designed as a fork, in which rollers 10 and 11 are vertically mounted at different heights, which interact with the copiers 12 and figured stops 13, fixed on the frame of the machine 1 pivotally and spring-loaded.

At the end of the spindle 8 of the clamping mechanism, interchangeable stamps 14 with numerals are fastened (fastening screws not shown).

The rotation mechanism consists of an electric motor 15, a clutch 16 and a spindle 17, at the end of which replaceable dies 18 are mounted, similar to dies 14.

Along the edges of the frame 1 in the plane perpendicular to the mechanisms of cutting 4, figured cutters 19 are installed.

The plate 3 with the cutting mechanisms is provided with a mechanism for its reciprocating movement along the figured cutters 19 in the form of, for example, a rocker mechanism (conventionally not shown).

The blanks 20 are fed from the store along the chute 21 to the supporting platform 22 fixed to the frame 1.

The axis of symmetry of the swinging spring-loaded figured stops 13 coincides with

support site 22 and a store for blanks.

The machine works as follows. Billets 20 for details of the game "Lotto

served on the tray 21 to the support platform 22. At the same time, the plate 3 is moved along the guides 2 relative to the bed. In this case, the roller 11 runs over the figured stop 13, and the rod 5, moving in the support 7, is retracted to the extreme right position (Fig. 2), and the spring 6 is compressed. In order to prevent the rod 5 from turning, under the action of a torque, prismatic guides are provided in the support 7.

When the plate 3, having made a reciprocating motion along the guides 2, reaches the end position, the roller 11 comes out of contact with the figured support 13. The spring 6 is opened and the rod 5 moves to the left in the support 7 and the dies

14 captures the workpiece 20. When the plate 3 reverses along the guides 2, the roller 11 pushes out the figure-stop 13 pressed by the spring, and the roller 10 runs onto the copier 12. The workpiece is pressed by the rod 5, and the replaceable dies 14 and 18

stamped on the end of the desired number. The rotation drive is turned on, so the clamped workpiece 20 slides over the shaped cutter 19 and is machined. Then, the plate 3 is retracted from the cutter 19, while the roller 11 moves along the figure stop 13 to its original position. The unclamping of the dies 14 and 18 occurs and the workpiece 20, fully processed, falls into the container for the finished products. When the roller 11 comes down from the figure stop 13, the rod 5 under

the action of the spring b captures the new workpiece.

Since the machine is made of two cutting mechanisms, the processing of the workpieces 20 is carried out sequentially during the return stroke of the plate 3, repeating the whole described process for another workpiece.

Thus, the processing of parts is carried out consistently, eliminating idle and fully manual labor.

An increase in the productivity of the proposed machine in comparison with the known ones is achieved by eliminating manual labor, combining the operations of clamping the workpiece and simultaneously stamping the numbers, as well as eliminating idle strokes.
