Abstract

Use: woodworking. SUMMARY OF THE INVENTION: The machine comprises a bed 1, a blade shaft 2 and pinch rollers 5. The front 7 and rear 8 tables have a lever mechanism 6 for moving them and are spring-loaded relative to the bed by springs 9. The bed is equipped with folding supports 13 for setting the tables in the upper position. When supplying the blank for the fuging operation, the rollers 11 are absent on the front table, the tables are set in a known manner. When gauging rollers 11 are mounted on the front table, their top forming surface 14 of table 8 is in the same plane that is located above the cutting circle. Tables 7 and 8 are flexible and press the workpiece against the pressure rollers. 1 il.

I

The invention relates to the woodworking industry, in particular to universal equipment for processing wooden workpieces.

The purpose of the invention is to expand technological capabilities and improve safety.

The drawing shows the proposed machine.

The machine consists of a bed 1, a knife shaft 2 and an arm 3 are fixed on it 10, along the groove 4 of which the pressure rollers move 5. In addition, the front 7 and rear 8 tables, which are spring loaded with springs, are mounted on the bed 1 using parallelogram lever movement mechanisms 6 9. In the front table 7, sockets 10 are made, into which easily removable rollers 11 are installed.

Mechanisms 6 _; the movements of the tables 7 and 8 20 contain clamps 12 and interact with the tilting stops 13 of the bed, which establish the working surface 14 of the rear table 8 and the plane 15. passing through the upper generators of the rollers 11 25 0.5-1 mm above the cutting circle (cutting edge of the knife 16 at its upper position).

The machine operates as follows.

When jointing, tables 7 and 8 are set to the required height (determined by the norms for conventional jointing machines) with the help of moving mechanisms 6 and are fixed with clamps 12. Moreover, the rollers 11 are not installed on the machine.

When switching to thicknessing operations, the pressure rollers 5 are set to a height relative to the cutting edge of the knife 40 16, equal to the thickness of the product, and the rollers 11 are installed in the nests 10. The mechanisms 6 for moving the tables 7 and 8 are unlocked, while the springs 9 raise the said tables. The movement is carried out before the interaction of the movement mechanisms 6 with the stops 13.

The machine is turned on and a workpiece is drawn into the gap between the pressure 5 and support rollers 11, which, having a greater thickness than the gap, rests on the pressure rollers 5 and moves the front table 7 down through the rollers 11, while the spring 9 of the front table 7 tends to raise the table 7 , pressing the workpiece to the pressure rollers 5. When the workpiece moves, it is machined to the size, while its front end interacts with the front face of the back table 8 and moves it, and the table 8 is lowered and the workpiece passes over it.

The spring 9 of the rear table 8 also compresses the workpiece to the pressure rollers 5. The reverse stroke of the workpiece is excluded due to jamming of the workpiece between the pressure rollers 5 and the working surface 14 of the rear table 8.

This ensures the exclusion of the ejection of the workpiece, i.e. safety improvement.

When the stops 13 are removed, tables 7 and 8 can rise, moving to each other, until they close above the knife shaft 2. which increases safety during sawing, milling, etc., operations.
