Abstract

Usage: in woodworking. The inventive thicknessing machine includes a fixed table 1, a knife shaft 2 with a drive, a support device in the form of a block 4 of smooth smooth rolls 7-10, a mechanism for clamping workpieces in the form of spring-loaded strips 17 with a notch on the outer surface, the base 16 of which interact with a movable wedge 15. There is a chip suction nozzle 22. The roller 10 is made eccentric. During the processing of different thickness blanks, the roller 10 interacts with the front end of one of the blanks, recesses it due to the spring bars 17 and advances to the next drive rollers 7-9. The workpiece with the non-machined side is rigidly pressed against these rollers due to the spring-loaded planks 17. 1 zpp-file, 5 silt.

The invention relates to technological equipment for processing non-metallic billets and can be used in the woodworking industry.

The purpose of the invention is to reduce vibration and noise levels, expanding the technological capabilities of the machine.

In FIG. 1 shows the machine, front view; figure 2 is a view of B in figure 1; on figs - view a in fig. 1; figure 4 is a section bb in figure 2; figure 5 - kinematic diagram of the machine,

The thicknessing machine includes a table 1, a knife shaft 2, a drive of a knife shaft 3, a block of feed rollers 4, a feed box of a drive of rollers 5, an electric motor 6 of a feed box, smooth rollers 7, 8, 9, an eccentric roller 10, a rack 11 with right guides, rack 12, screw 13, screw drive 14, wedge 15 movable, base 16 of the straps, strap 17 with a notch, springs 18, strap 19, gears 20 of smooth rollers, spurious wheels 21, nozzle 22 of the chip suction, workpiece 23.

A strap 19 is fixed on the table 1, a wedge 15 is installed along with the base 16 of the bars 17. Between them are the springs 18, the left stand 12 and the right stand 11. In the lower part to the table are fixed: drive 3 of the knife shaft 2, chip suction pipe 22; the block of four feed rollers 7. 8, 9, 10 is mounted on the rails of the right strut 11. A screw 13 enters the threaded hole of the block, the drive of which 14 is mounted on the left strut 12. The drive 5 and the electric motor 6 are connected via a V-belt drive to a smooth roller 8, and the gears 20 and spurious wheels 21 are engaged with each other. The workpiece 23 is located on the bar 17.

The machine operates as follows. The rotation of the drive 3 is transmitted to the knife shaft 2 1, the rotation from the electric motor 6 is transmitted to the feed box; From there, to the gear wheel 20 and further to the spurious gear 21. The gears are rigidly connected to the smooth rollers. Thus, the rotation of the latter is ensured.

The workpiece 23 is mounted on the table 1 with the surface to be treated. First, it is laid on the strips 17 and is sent under the eccentric roller 10, which rotates, recesses the bar and simultaneously moves it in the longitudinal direction under the smooth roller 9. The springs 18, acting on the strips 17, press the bar against the smooth rollers. The roller 8 provides the passage of the NED bar with a knife shaft, and

the roller 7 provides, together with the rollers 8 and 9, the supply of the bar until its final processing.

If a number of different thicknesses are supplied

bars, then the roller 10, acting on them, aligns the planes of the bars parallel to the machined surfaces, recessing the bars by an amount corresponding to the height of each bar. Thus, the upper surfaces of the bars are in the same plane as the smooth rollers. In this case, the strips 17 are moved in an upright position and by a different amount, compensating for the difference in thickness of the bars. The chips are removed through the suction nozzle 22. The following adjustments are provided in the machine: according to the height of the processed bars by moving the block 4 relative to the outside

the plane of the bar 19, according to the magnitude of the effort of pressing the bar against the rolls by displacing the base 16 using a movable wedge 15.

Moving the feed rollers is carried out using a screw 13, which receives rotation from the drive 14. Formed during cutting, the chips are removed using the suction nozzle 22. The counter 11 is guiding when moving the block of feed rollers, and the counter left 12 receives the force from the screw 13, moving the feed roller block.

Compared with the prototype, the inventive machine has a number of advantages.

By positioning the knife shaft and the chip suction nozzle inside the fixed table, isolation from surrounding noise sources is achieved. and.

consequently, a reduction to its sanitary standards. Reliable clamping of the bars during processing, especially in the cutting zone, eliminates their vibration. Notches on planks in the form of sharp teeth facing

in the direction of movement of the workpiece, prevents the ejection of the workpiece during manual loading of the machine. Smooth feed rollers serve for this purpose, and the bond of the workpieces with them does not stop during processing. For this reason, there is no claw protection device in the machine.
