Figure 2 is a view A-A.

Figure 3 shows the means for fixing reinforced billets.

Figure 4 shows the clamping mechanism.

Figure 5, 6 and 7 depict various configurations of the upper knives.

Installation for cutting strips of reinforced preform contains Electromechanical device 1 mounted on the rack 2, installed on the base plate 3. The device consists of an actuator 4 that is installed on the carriage 5, and the movable knife 6, reciprocating movement in a vertical plane. In the plate 3 has two rigidly fixed blade 7, separated by a gap 8 for the passage of podi the nogo knife. With the upper and lower sides of the plate is made of longitudinal guide grooves, respectively, 9 and 10, connected extended through the slit 11. In the crack set means for fixing reinforced preform 12.

The means 12 consists of a washer 13 is installed in the top of the longitudinal groove 9, the guide nut 14 in the lower groove 10, the cylindrical sleeve 15 mounted on the washer 13, and a screw 16 that is installed inside the sleeve 15 with the stop of the screw head at its end. The washer may be provided with a pointer (Vizir) 17. In the center of the washer 13 may be made of the recess 18 in which is mounted the sleeve 15.

On the cylindrical sleeve 15 of the fixing means 12 can be mounted clamping mechanism 19, consisting of a sleeve 20 with an external thread 21 on one end of the sleeve and the flange 22 at the other end and the washer 23.

Washer 23 communicates with the external thread of the sleeve 21. Between the flange 22 and washer 23 is formed a space for clamping reinforced preform 24.

The unit can be equipped with a 25 foot, reinforced retaining the workpiece, and the line 26, is installed on the base 3 parallel to the longitudinal groove 9.

The device operates as follows.

With the handle of the carriage 5 movable knife 6 is installed in the gap to a depth of 2-3 mm, Then use the reticle 17 and line 26 is set to the desired radius of the good is ADCI, which is fixed by means of 12, consisting of a tightened bolt 16 washers 13 and nuts 14 and sleeve 15. In the reinforced stocking 24 punch. Through the aperture of the workpiece is put on the sleeve 15, is clamped by the presser foot 25, then, while rotating the workpiece in a clockwise direction and the perforation of the upper knife 6 driven by the actuator 4 is the cutting strip.

Strip obtained in this way can have a very different shape. However, punched a hole in the process of cutting pads varies in size, which leads to a distortion of the specified form cut pads - if you run spacers in the form of a circle, the result obtained circumference can buy ellipsoid shape.

To improve the dimensional accuracy of the cut strips of the workpiece 24 is first mounted in the clamping mechanism 19, consisting of a sleeve 20 with a thread 21 and the flange 22 between the flange and the sleeve 23, is fixed by screwing the sleeve, and then Assembly mounted on the sleeve 15 of the fixing device 12, and then, rotating the sleeve 20 of the workpiece 24, they cut the workpiece circumference.

The use of the upper knife with different forms of blades additionally, you can extend your installation. Thus, the use of a knife in accordance with figure 5 allows you to cut strips in esname circuit. Knife in accordance with 6 allows you to cut the inner contour of the strip upon receiving it in the form of a ring, and a knife in accordance with 7 to produce a large line of cut with high quality and can be used for the production of several strips - one of the cut parts will be the outer contour of the first strip and the second internal circuit of the second strip.
