Abstract

The invention relates to a device for measuring cutting wire and improves the reliability and durability of the device. On base 8, a housing 9 is fixed, on which a spring-loaded disk 4 with a vertical axis of rotation and an annular friction lining 17 is mounted with the possibility of angular rotation, as well as an inertial movement limiter made in the form of an L-shaped rod, the horizontal shelf of which is provided with a friction lining. The fixed disk is mounted for engagement with a movable disk in which knives are installed and there are radial grooves for accommodating stops made in the form of adjustable prismatic rods with wedge tips. A spring loaded friction disk 3 with a horizontal axis of rotation interacts with disk 4 and is connected with feed rollers 5 and 6. A wire is placed between the feed rollers 5 and 6. A moving disk with knives is set in motion, an adjustable stop causes the spring loaded disk 4 with a vertical axis to rotate rotation, which through the disk 3 and the feed rollers 5 and 6 moves the wire to the cutting zone. 3 hp f-ly, 5 ill.

The invention relates to metalworking, namely to devices. For measuring wire cutting, incl. from refractory alloys,

The goal of the invention is to increase the reliability and durability of the device.

Figure 1 shows the device, section aa in figure 2; figure 2 is the same, top view; in Fig.3 is a section BB in Fig.2; figure 4 is a view In fig; figure 5 is a view of G in Fig.Z.

The fixed disk 1 is mounted to interact with the movable disk 2. A spring-loaded friction disk 3 with a horizontal axis of rotation interacts with a spring-loaded disk 4 with a vertical axis of rotation and is connected with the feed rollers 5, 6. The limiter 7 of inertial motion is mounted on the base 8, on the body 9, which serves to accommodate the shaft 10, inside which the compression spring 11 is mounted, is fixed. A spring-loaded friction disk 3 with a horizontal axis of rotation is placed on axis 12, and the feed roller 6 is on axis 13, which is fixed in a spring-loaded insert 14, pressed against the lid 15. The spring-loaded insert 14 is installed in a groove made in the plate 16. The spring-loaded disk 4 with vertical the axis of rotation is provided with an annular friction lining 17. The plate 16 is rigidly connected to the elastic housing 18. In a spring-loaded friction disk 3 with a horizontal AXIS of rotation, pins 19 are fixed, and screws 20 fasten 15 to the plate 16. Screws 21 are installed in plate 16, screws 22 — in the elastic housing 18, and the screws 23 — in the base 8. L-cut screws 24 secure the base 8 to the guide rails, for example, a lathe (not shown). The limiter 7 of the inertial movement is made in the form of an L-shaped rod

with a horizontal shelf 25. Screws 26 secure the housing 9 to the base 8. Nuts 27 and 28 secure the plate and the elastic housing 18, respectively. The spring ring 29 determines the position of the feed roller 6 on the axis 13. A bearing 30 is placed on the shaft 10, Pechivanadiy ease of rotation of the spring-loaded disk 4 with a vertical axis of rotation. Kriszha 15 is spring-loaded with spring 31 relative to liner 14, and spring 32 ensures that the friction disk 3 is pressed against the spring-loaded disk 4 with an annular friction lining 17. The horizontal shelf 25 of the L-shaped rod 7 is provided with an additional friction lining 33 interacting with the end surface of the friction disk 4 with a vertical axis of rotation. Spring washers 34-37 ensure reliable fastening of the parts 15, 9, 7 and 24. Precise fixing of the housing 9 relative to the base B is achieved using pins 38. Each adjustable stop is made in the form of a prismatic rod 39 placed in the radial groove 40 of the movable disk 2. Prismatic rod 39 has a wedge-shaped tip 41. and a groove 42 into which the screw shaft 43 enters. Rotation of the movable disk 2 is provided, for example, by fastening the shank 44 in the lathe chuck (not shown). The knives 45 are fixed in the movable disk 2, and the fixed disk by means of a conical shank 46 - in the hole of the quill 47 of the tailstock 47 of the lathe (not shown) ..

The device works as follows. .

Before cutting the wire, the prismatic rod 39 moves in the radial groove 40 and extends from the movable disk 2 to a certain

the value depends on the length of the dimensional elements into which the wire should be cut. Before cutting, the knives 45 are fixed in the movable disk 2 so that their part protruding from the end face of the disk 2 is equal to the length elements of the wire. The wire is then placed between the feed rollers 5 and 6 and the movable disk 2 c 45 is rotated. With its wedge-shaped tip 41, the prismatic rod 39, in contact with the spring-loaded disk 4 with the vertical axis of rotation, moves it down and it comes out of contact with the additional friction pad 33 placed on the horizontal shelf of the inertia limiter 7. At the same time, the disk 4 also rotates; with its annular friction lining 17, the spring-loaded disk 3 with a horizontal axis of rotation rotates. The spring-loaded friction disk 3 uses the pins 19 to rotate the feed roller 5 ,. which, rotating together with the roller 6, moves the wire to contact with the end face of the movable disk 2, the knives 45 of which are made after this piece of the Wire measuring element the spring 11 moves upward, comes into contact with the additional friction pad 33 of the L-shaped rod 7 and stops by friction forces.

The proposed device, in comparison with the prototype, is distinguished by greater reliability and durability.
