DEVICE FOR METAL SILICON WITH NIZA

V21LZ / 00

The device relates to tools and devices that provide forging processes of large forgings. Known corners for cutting ledges but forgings. in some sources they are called Triangular pinches Г ll, which are intended for cutting the ledges of stepped forgings. On large presses or presses with great efforts, for example, on a press of 10,000 ton-force, corners (triangles) have undergone structural changes relative to the indicated normal and have an additional tail of rectangular cross section, which is assembled on special rocker arms, and suspended from an axle suspension device, corner, etc. separation tool C23.

However, the indicated corner constructions and devices for their suspension provide a cut-in of metal from the top. Given that the corners for these presses have significant masses, plus the mass of the rocker arms, on which two corners are suspended for balance, the worker has to work in very difficult and dangerous conditions. The great complexity of the process is to install the corners after the first undercut when turning the forgings of large diameter on the line of the next undercut. Given that almost all modern presses are equipped with manipulators, it seems more appropriate to have a corner located rigidly from the bottom, and manipulate setting it to contact with metal for cutting to adjust the movement of the workpiece itself by means of a forging manipulator. Such a task was the subject of temniks. However, it was not solved, since there was no rational, reliable, but simple design of the device for its implementation.

The aim of the invention is to develop a method and device that improves productivity, quality and reduces the complexity of metal cutting.

The goal is carried out by a device for cutting metal from the bottom and is shown in the drawing.

On $ ig. 1 shows a general view of the device;

on $ ig. 2 - view A of Fig. 1;

in Fig.Z - section bb In Fig.2.

The device consists of a lower housing I, in which a longitudinal groove is made from the side of the upper end, i.e. the vertical walls of its 2 are made obliquely. In the center of the groove on the horizontal plane 3 there is, for example, a socket in which a fastening centering key 4 is installed. Through grooves are made in the transverse direction from the sides of the lower case 5. An angle b containing the dovetail 7 is installed in the J-shaped groove, side face 8 of which is made with a slope mutually parallel and adjacent, corresponding to the side branches of the groove of the lower case. In the transverse direction on the dovetail, through grooves 9 are made, co-main grooves 5 of the lower body. An groove 10 is made at the lower end of the dovetail corners, interacting with the mounting centering key 4. To attach the corners 6 to the lower case I, an ixator II is provided, which is passed through the transverse grooves 5 and 9 of the lower body of the striker I and the dovetail corners 7.

The operation of the device is as follows. The workpiece is set by the manipulator on the corner and the upper striker applies force to the upper sections, as a result of which sections of the notch from the bottom are obtained.

The slopes on the lower housing of the groove and on the dovetail corners are provided for convenience when removing corners, in cases of possible deformation of the cross section of the latter during hot crimping.

To cut metal from the bottom, it is necessary to set the corner at such a height that it corresponds to the location of the axis of the trunk of the manipulator, i.e. at the height of the usual lower bodies or press brackets 3, and taking into account the location from the trunk is taken into account by the height of the inserts installed in the lower body strikers 4..

The device proposed by the application solves the existing technical problem with the following distinctive features:

- a longitudinal groove of a W-type is made on the lower case;

- in the transverse direction of the lower case, through grooves are made through the grooves;

- a dovetail is provided at the bottom corner;

-interacting with a groove of the lower case;

-the side faces of which are made with slopes;

- mutually parallel and adjacent to the corresponding side walls of the groove of the lower case;

- from the transverse side of the walls of the groove of the lower body and the side inclined faces of the dovetail, the corners are made coaxially through the grooves;

-In which are installed | Ixators. Relatively new from the level of science and technology.

Let us dwell on some, requiring clarification.

In the practice of forging the production of large forgings on presses that pressurize the top drive with the operation of cutting, chopping, etc. produced by the top brisk contact on axes and corners. Similar operations from the bottom will have to be carried out by pressure of the upper striker on the forging, and the forging will not be on the lower striker, but on the tip of the corners. Therefore, direct analogues and prototypes were not found.
