SU1238978A1 - Device for protecting vertical rotary machine working tool from breaking - Google Patents

Description

The invention relates to forging and pressing machinery, in particular, to the design of safety devices.

The purpose of the invention is to increase the reliability of the machine and the durability of the working tool.

FIG. 1 shows the device in the initial position of the upper and lower parts of the working tool, general view; in fig. 2 - the same, with closed parts of the working tool, in the process of processing the workpiece; in fig. 3 - the same, in the absence of a blank between the parts of the working tool, in FIG. 4 is a view A of FIG. 2; in fig. 5 shows the node I in FIG. one; in fig. 6 — node II in FIG. one.

The device contains placed in a cylindrical slider 1 of the machine with the ability to interact with the upper part 2 of the working tool rod 3, spring-loaded relative to the slider 1 by means of a spring 4 and the sleeve 5 concentric with it with a conical end 6, rollers 7 with conical ends 8 and placed between the rollers 7 elastic element 9, as well as a shock absorber 10 installed with the coverage of the rod 3 between the end face of the slide 1 and the upper part 2 of the working tool. The rollers 7 are placed in the holes 11, made in the slider 1 perpendicular to its axis. In the sleeve 5, from the side of the lower part 12 of the working tool, there is a conical cavity 13, and the sleeve 5 is installed with the slider 1 encompassing. Above the sleeve 5, a nut 14 is placed on the slider 1 to adjust the position of the sleeve 5 along the slider 1. Lower part 12 of the working tool installed on the stock 15 of the machine.

In the initial position, the thrust end

The device works as follows. If there is a condenser housing 19 with a foil outlet 20 on the lower part 12 of the working tool while moving the slider 1 with the sleeve 5 down, the latter with its conical cavity 13 abuts the case 19. Further movement of the slider 1 downwards causes the slider 1 to compress the spring 4, and the sleeve 5 is displaced relative to the slider 1, the interaction of its conical end 6 with the conical ends 8 of the rollers 7, shifting the latter to the axis of the slide 1, compressing the elastic element 9. In this case, the stop end 16 of the rod 3 receives a hard stop in the form of rollers 7, h This ensures the normal operation of the machine, i.e., cold welding of housing 19 with a foil lead 20.

During the return stroke of the slider 1, the sleeve 5 returns, thanks to the spring 4, to its original position, as well as the rollers 7, thanks to the gift of the elastic element 9.

In the absence of the housing 19 on the lower part 12 of the working tool, when moving the slide 1 with the sleeve 5 down, the lower part 12 of the working tool enters the sleeve 5, abutting the top part 2 of the tool, compressing the shock absorber 10. At the same time, the rod 3 moves up and passes between the rollers 7, entering into the holes 11, ensuring the absence of force interaction between the parts of the working tool, i.e. eliminating the possibility of it breaking15

During the return stroke of the slide 1, the rod 3 with the upper part 2 of the working tool returns to its original position.

The technical and economic effect of the introduction of the stock 3 of the rod 3 is shifted downwards relative to the bearing of the invention, is provided by

version 11, and the flat ends 17 of the rollers 7 are offset to the side relative to the hole 18 of the slide 1.
