Description

In the proposed invention, with regard to the device of the machine with an end rim saw, a suitably arranged feeding mechanism and zhehanizm are collectively used to communicate the rocking saw

In the schematic drawing, FIG. 1 is a side view of the proposed machine; FIG. 2iZ-transverse sections of it; FIG. 4- giving mechanism; FIG. 5 - transmission from the drive shaft to the feed roller; FIG. 6-top view of the machine.

A circular saw 2 (Fig. 1; 2), protected by a casing 1, is driven by a pulley 5 sitting on the drive shaft 5 by means of an endless belt 35 and a pulley, 4, whereby the ratio of the rotation speed of the pulley 5 to the pulley 4 as 1 : 3. Sitting on the same shaft 5, the gear 8 rotates three times the larger gear 7, mounted on the shaft 7. On the shaft 5, in addition, the bevel gear 9, the rotating roller 31 is mounted, by means of the gear 10. The gear 11 on the roller 31, into its turn, rotates the bevel gear 12, mounted on the shaft 12, which causes the roller 25 to rotate (FIGS. 5 and 6), which has teeth around the circumference to grip the machined

subject 26 (Fig. 4). In the bearings 23 (FIG. 2) connected to each other by the frame 15, the saw shaft 2 and the drive shaft 5 rotate with the pulley 5. On the drive shaft 5 a pulley 6 is mounted, transmitting, by means of an endless belt. from car to saw. The entire system with four bearings 23, a shaft 2, a pulley 4 and a saw 2 is rotated on the shaft by means of a rod 13 receiving movement from a finger 27 on gear 7 and equipped with a hinge 28 placed in the slit 24 of the frame 15 (Fig. 1). On the shaft 7, there is a passenger eccentric 20 with goy 14, a bolt 29 with a lever 16 pivoting around point 17, an end 18 of which is fastened with a brace 34 connected by ends with an axis of the roller 3 that presses the lever 29 up to the top, pressing down , in turn, on the rollers 19, mounted on the springs 33; the springs 33 are stretched and the workpiece 26 together with the rollers 19 is lowered, the entrance to the contact with the teeth of the rotating roller 25, which advances the board by a certain length. When the end 29 of the lever 16 is lowered, the destabilization between the roller and the object being processed is broken and the hearth stops at the last. The rod 13, by means of a strap 28, slides the rotating saw onto the board and, after the latter has been sawn through, returns the saw to its original position shown in FIG. one.

In this way, the workpiece is cut into pieces of the same length. Shafts 5 and 7 lie, each, in two bearings 21,22, reinforced in a fixed frame 30.

The subject of the patent.

A machine with an orchid circular saw, characterized by the combined use of: 1) a mechanism for communicating the saw rocking movements, consisting of associated with the frame 15, by means of a rocker slot 24 and a hinge 28, a rod 13, receiving movement from a finger 27 on the / wheel 7 interlocking with gear 8 on the drive shaft of the saw, and 2) a feeder mechanism consisting of an eccentric 20 fixed on the shaft 7 of the wheel, indicating a swinging motion to the lever 14-17-18, transmitting these swings using the bracket 34 to the roller 3 designed periodically about press the workpiece 26 on the workpiece, and, through bliss and on the rollers 19 suspended from the fixed supports by means of springs 33, in order to press the object on the drive roller 25, receiving constant rotation from the machine's drive shaft using two pairs of bevel wheels 9,10 and 11, 12 and their corresponding shafts.
