Description

The invention relates to the woodworking industry, in particular to equipment for processing blanks of knife handles.

The purpose of the invention is higher productivity due to simultaneous cutting of half-closed grooves in the handles of knives.

Fig. 1 shows a machine for processing wooden blanks of knives handles, side view; Fig. 2 is the same, top view of Fig. 3, section A-A in Fig. 1, Fig. 4 shows a Z-shaped support for workpieces with a bracket and a spring-loaded two-arm lever with a roller.

The machine for processing blanks of knives handles includes a frame 1s. On which the drive 2 is fixed, transmitting rotation to the saws 3 and 4 (1 fixed on the main 5 and additional 6 saw shafts, and gears 7 and 8, rotating in the caliper 9, bracket 10 with a gshank 11, on which a double-arm lever-stop 12 is hinged on an axis, consisting of a support plate 13 rigidly connected to two side slats 14, at the opposite end of which a weight 15 is fixed, i.e. a load 15 is fixed on back to 10

The position of the lever 36 is controlled by means of an adjusting screw 40. The machine is also equipped with a guide plate 41, a tray 42 and a casing 43 covering the saws 3 and 4. The adjustment of the guide plate 41 and the support plate 13 relative to the axle of the saw 3 ( the position of the axis of the saw 4 relative to the axis of the saw 3 is set by the caliper 9 and is not subject to adjustment) carried out by means of adjustment plates 44 and 45. The length of the grooves 30 and 31, cut through in the workpiece 17, is adjusted with the help of 5 Z-shaped stop 32, and the depth help adjusting layer John 44 and 45.

The machine for processing blanks of knives handles works as follows.

When the actuating cylinder 19, which interacts with the shutter 18, is triggered, the next billet 17 from the magazine 15 enters the gripping zone located between the clamping jaws 29 o The blank 17 at one end rests on the guide plate 41, and the other interacts with the support plate 13 double-lever arm 12,

The board for feeding the blanks to the shoulder of the fish, which, under the weight of the billet chaga-stop 12. In addition to the tggo, the machine 17 occupies the position shown contains the magazine 16 with the blanks 17 in figure 1 with a solid line. After that, the cutter 18, brought into deist operation, includes the power cylinder 25,

Viy power cylinder 19, the mechanism

20 clamp billets power cylinder

21 with guides 22 fixed to frame 1. Plank 23 serves to adjust the clearance between guides

22 and the work clamping mechanism 20. The work clamping mechanism 20 is located in the self-centering cartridge and consists of a body 24 with a power cylinder 25 fixed on it, which is driven by means of two shoulder arms 27 slats 28 connected to the clamping jaws 29 on the axes 26. the final fixation of the workpiece 17, in which it is necessary to cut two semi-closed grooves 30 and 31 with the saws 3 and 4, is a Z-shaped stop 32 for the workpieces 17 as a longitudinal groove 33 for the saw 4;

. the stem of which interacts with the double-35 arms 27, which rotate around the axes 26, shear strap 28 and the associated jaws .29, clamping the workpiece 17. After clamping the workpiece 17, the power cylinder 21 moves the mechanism 20 for clamping the workpieces together with the workpiece 17 into the work area to the Z-shaped stop 32, where the saws 3 and 4 cut through the workpiece 17 grooves 30 and 3J. In order for the moment of contact of the workpiece 17

With the saw 4, the fixation of the workpiece 17 did not break. It was spring-loaded, 35 double shoulders lever 36 with roller 39. Freed from the weight of the workpiece 17 double shoulders lever 12, the load 15 is lowered by the load 15, the power cylinder 21 switches backward, returning the workpiece clamping mechanism 20 together with machined 34 with a spring loaded spring 35 with a two - workpiece 17 into the original with a posterior arm 36 mounted on the axis 37. At the end the lever 36 on the axis 38 is fixed by a support roller 39, Regu

The position of the lever 36 is controlled by means of an adjusting screw 40. The machine is also equipped with a guide plate 41, a tray 42 and a casing 43 covering the saws 3 and 4. The adjustment of the guide plate 41 and the support plate 13 relative to the axle of the saw 3 ( the position of the axis of the saw 4 relative to the axis of the saw 3 is set by the caliper 9 and is not subject to adjustment) is carried out by means of adjustment plates 44 and 45. The length of the grooves 30 and 31, cut through in the workpiece 17, is adjusted by means of a Z-shaped stop 32, and the depth adjusting plate 44 and 45.

the stem of which interacts with double-arm levers 27, which rotate around the axes 26, shear strap 28 and associated jaws .29, clamping the workpiece 17. After clamping the workpiece 17, the power cylinder 21 moves the workpiece clamping mechanism 20 together with the workpiece 17 into the work area to the Z-shaped stop 32, where the saws 3 and 4 cut through the workpiece 17 the grooves 30 and 3J.

With the saw 4, the fixation of the workpiece 17 did not break. It was spring-loaded, 35 double shoulders lever 36 with roller 39. Freed from the weight of the workpiece 17 double shoulders lever 12, the load 15 is lowered by the load 15, the power cylinder 21 switches back, moving the workpiece clamping mechanism 20 together with processing. Then the power cylinder 25 expands the clamping jaws 29, freeing the workpiece 17, which is not supported by the two-arm lever-stop 12 (the support plate 13 is above the workpiece 17), falls down to the tray-slither 42, from where it falls into - RU. Power cylinder 19 returns cutter 18 to its original position, and the cycle is repeated.
