Abstract

The invention relates to woodworking machinery and can be used in the production of wooden wedges. The purpose of the invention is to increase the productivity of the machine. The machine includes a frame 1, a drive roller table 2, guides 3 mounted at right angles to the longitudinal axis of the roller table 2 with a saw support 4 mounted on them with rollers 5, a circular saw and an electric motor. The support 4 is connected by a crank mechanism 8 with a drive 9. The machine also contains an additional saw support 11, similar in construction to the support 4 and installed at an acute angle to the longitudinal axis of the roller table 2. The drive of the roller table 2 is made in the form of a bevel gear drive, in which the gear is mounted on the roller shaft of the roller table 2, and the knowledge of the gear is connected through the overrunning and cam clutches with the gear in contact with the rack mounted on the main saw support. The workpiece is placed on a roller conveyor 2, with which it is moved by the amount of the part being cut when the support 4 is idle. The additional support 11 cuts the parts into a wedge. 5 il.

The invention relates to woodworking machinery and can be used in the production of wooden wedges,

The purpose of the invention is to increase productivity.

Figure 1 shows the proposed machine, a general view; figure 2 is the same, top view; on fig.Z - section aa in figure 2; figure 4 - section bb in fig. on fig.Z - section bb In fig14.

The machine for making wooden wedges includes a frame 1, a drive roller conveyor 2, guides 3 mounted at a right angle to the longitudinal axis of the rollers. On the guides 3, a saw-support A is mounted with rollers 5, a saw 6 and an electric motor 7. The saw-support 4 is connected by a crank mechanism 8 with an actuator 9.

The machine is also provided with additional guides 10 installed at an acute angle to the longitudinal axis of the roller table 2. Guides 10 also have a saw support 11 connected by a crank drive mechanism 12 with a drive 13. The roller table 2 is complete in the form of gear bevel gears 1A and 15. Moreover, the bevel gear 14 is mounted on the shaft 16 of the roller 17, and the gear 15 is equipped with an overrunning clutch 18 and connected with a cam clutch 19 to the shaft 20 on which the gear is fixed 21. The gear 21 contacts the gear rack 22, fixed and sawing the caliper 4. Rollers of the roller table 2 are interconnected by chain gears 23, mounted on the roller table 2 and the pressure roller 24, moreover, shows a wooden billet nna 25 nny wood wedge 26, the container 27.

The machine works as follows.

The workpiece 25 is placed on the roller table 2 under the pressure roller 24. Turns on the drives 9 and 13, Saw calipers 4 and 11 make working strokes. With

This caliper 4 performs a cross-cutting of the workpiece 25, and the caliper 11 makes the first move idle. In

the travel time of the slide 4 of the live rolls 2 does not rotate due to the overrunning clutch 18. During the return stroke of the saw slide 4, at the first moment the live rolls 2 also do not rotate,

as the clutch cams 19 are not yet in contact. After the saw 6 leaves the zone of the workpiece 25, the cams of the clutch 19 come into contact and the gear 15 turns the gear 14,

and the rollers 17 of the roll table 2 also rotate with it. The workpiece 25 moves by a measured amount. Then again calipers 4 and 11 make a working course. Caliper 4 makes a transverse cut, and caliper 11 cuts the resulting piece of the workpiece at an acute angle into a wedge. At the end of the roller table 2, the wedges are collected in container 27.

The use of the proposed machine allows to increase the productivity in the manufacture of wooden wedges.
