Description

Patent No. 21437 describes a machine for the manufacture of plaster drani, in which a cutter bar was used to cut the entire width of panels and cut them into shingles, which received a reciprocating motion from the crank mechanism, and two wedges, which were similar, were used to feed the workpiece. with the help of a screw with right and left cuts, in order to move the table in the vertical direction by the thickness of the draika.

In the proposed modification of the machine, the billet is supplied to the plow cutters by means of a rack-mounted spring platform connected to the billet supporting the ratchet gear, which is rotated at the end of the plow idling.

In FIG. 1 is a side view of the machine; FIG. 2 is a front view of it; FIG. 3 - his match; FIG. 4 side view of the plow; FIG. 5 view from the back; FIG. 6 view it from above.

On the frame J9, supported by legs //, 12, 13, a platform / 5 is placed, on which the workpiece 9 is fastened. The platform, besides its own weight, is pressed to the table 19 by springs / 5, which are attached to the rods 17, which serve as guidelines for platform when it is lifted above the table. Dran from the workpiece

9 is removed by means of a plow, receiving reciprocating movement from a connecting rod 2 connected with a finger on a flywheel 3 mounted on a shaft 10 driven by a pulley 14 from a drive (Fig. 2, 3). The guides for the plow / when moving it in the horizontal plane are the rods 22, fixed in the uprights 4 of the bed 19. To feed the workpiece 9 to the pliers / serve, is the rack 4, attached to the platform 18 and interlocking with the gear wheel 5, which is at the same time, a ratchet fitted with a locking pawl 16 and a working pawl on the rod 6 carrying the cross member 5 and the spring 7 placed between the cross member and the guide post for the rod b; , at the end of the idle stroke, the plane /, resting with its protrusion 10, on the cross member 5, moves the rod 6 to the right, with the pawl of which the wheel 5 turns and the platform 18 rises with the workpiece 9 by the thickness of the splint. When working stroke, the plow / spring 7 retracts the rod 6 with the dog in its original position. Plow 1 is provided with one horizontal knife 25 for cutting from the workpiece 9 full-width panels and vertical blades 25 for cutting the panels into shingles.

Subject invented.

In the machine tool described in patent No. 21447, a device for feeding the workpiece 9 to plow cutters /, characterized by

using a spring-supported platform 18 -

a gear rack 4 coupled to a gear wheel 5, a ratchet at the same time, provided with a locking pawl 16 and a working pawl on a spring rod 6 with a cross member 8, which the protrusion 10 acts on when it is idling at the plane 1.
