SU1209366A1 - Arrangement for shaping chip root - Google Patents

Description

The invention relates to machine tools and can be used in the study of chip formation and contact phenomena in the cutting process, including the processing of the friction disk.

The purpose of the invention is to simplify the design of the device for obtaining the chip root.

Hd figure 1 shows the device, a general view; Fig. 2 shows a lock of instantaneous action.

The device for receiving the chip root, in particular when machining with a friction disk, is fixed on a machine tool, for example, milling or turning, and consists of a base 1 with stand 2 and guides 3- in which the workpiece 4 is placed, a tool in the form of a friction disk 5, drive the removal of the workpiece from the tool, made in the form of a spring 6, spaced between the workpiece 4 and the stand 7 fixed on the base 1, the spring 6 being fixed on the mandrel 8, the workpiece 4 is fixed from moving by fixing the clamp 9 whose axis is parallel guides 3, an interaction with the rack 2, and equipped with a squib 10, a friction disk 5 is installed in the spindle 11 of the machine and processes the workpiece 4, remove the structure 5

The direction of supply of the claimed device with respect to the friction disk is shown by arrow A (Fig. 1).

The latch 9 (FIG. 2) is made in the form of a rod, on the side surface of which there is a slot for placement

a squib 10 fitted with an ignition wire (cord) 13. The locking ends are pointed and enter the sockets (recesses) 14 and 15 made in the rack 2 and the workpiece 4.

The device works as follows. in a way.

Investigated billet 4 with the prepared outer surface is installed in the guides 3. With the help of a lever (not shown) the billet is displaced to the right, compressing the spring 6 fastened on the rack 7 on the mandrel 8. On the other hand, the fixture 9 is installed between with their pointed ends into the recesses (sockets) 5 made in the rack 2 and the workpiece 4. The tool-friction disk 5 mounted on the spindle 11 of the machine is rotated. Move the device to get the chip core to the right along arrow A (). When this occurs, the cutting of the allowance and the formation of pp 12,

To stop the cutting process instantly, the squib 10 explodes during machining of the workpiece, knocking latch 9 upwards (Fig. 2), as a result of which the workpiece 4 under the action of the compressed spring 6 and the response from the cutting forces shifts quickly in the guides 3 of the base 1 to the left.

Then, a cutting zone is cut out from the blank in a known manner for further studies.
