Abstract

The invention relates to the processing of metals by pressure and can be used in mechanical engineering for the production of sheets with thickening on the edges. The purpose of the invention is the expansion of technological capabilities by increasing the length of the bulge. When the deforming roller (P) 6 acts on the edge of the sheet stock 9, it will thicken, bulging and forming a zig in the free zone ahead of P 6. The support roller 5 moves parallel to the direction of movement of P 6 and precipitates (rolls out) the formed ridge, as a result of which the thickening is aligned. The deforming 6 and podporny 5 rollers are installed respectively with the ability to move along the gap between the plates 1 and plates 3 and 4 and along the groove of the pressure plate perpendicular to their working plane m. A heating element 2 is installed in the support plate 1 under the roller 5. The device allows to obtain significant thickening along the edge of the sheet. 1 hp f-ly, 3 ill.

Description

eleven

The invention relates to the processing of metals by pressure and relates to devices for thickening the edges of the sheets.

The purpose of the invention is the expansion of technological capabilities by providing an increase in the length of the bulge.

FIG. 1 shows the device in the initial position, a longitudinal section; in fig. 2 - the same, in the process of forming a thickening; in fig. 3 is a view A of FIG. 2

The device contains a base plate 1 with heating elements 2, for example heating elements, mounted inside it along its entire length. A pressure plate is installed on the support plate 1, consisting of two plates 3 and 4, spaced from each other at a distance equal to the width of the retaining roller 5 and forming a groove between them. A deforming roller 6 is installed in the gap between the support 1 and the pressure plate, which can be moved in the axial and translational directions. The axial movement is provided, for example, by the mechanism 7 moving through the axis 8. Between the plates 3 and 4 of the pressure plate, a retaining roller 5 is installed along the groove between them and in the direction perpendicular to the base of the support plate 1 5 are located in one plane and perpendicular to each other.

The device works as follows.

Sheet billet 9 is installed on the support plate 1 and fixed on top of the pressure plate. With the help of heating elements 2, the deformation zone is heated along the entire length of the sheet stock 9 to a predetermined temperature. Install the bobbin roller 5 to its original position before touching the outer surface of the sheet blank 9. After that, the deforming roller 6 is placed into the gap between the support 1 and the pressure plates.

Using the mechanism 7, the working part of the deforming roller 6 is inserted into the end of the sheet stock 9 through the axis 8 and the process of deformation is performed, i.e. rolling the deforming roller 6 along the end of the sheet blank 9. When

The sheet material is deposited (thickened) between the base plate 1, the pressure plate plate 4 and the working surface of the deforming roller 6 into the gap with the material in the groove between the plates 3 and 4, in which the supporting roller 5 moves parallel to the deforming roller 6. Width the groove and, accordingly, the width of the retaining roller 5 is equal to the height of the required thickening. In the absence of a constant back-up over the entire length, a slight thickening occurs in the beginning of the upper part of the groove, t. closer to the deforming roller 6, and during further rolling, the workpiece 9 bulges between the plates 3 and 4 in the form of a ridge

2Q in the direction of the free surface. However, the use of a retaining roller 5 in the apparatus makes it possible to avoid this. The support roller 5 evenly rolls the metal over the entire height of the thickening zone, and when a ridge is formed on the free surface, it precipitates it to form an equal thickness thickening. The size of the settled part

30 sheet blanks 9 deforming

Roller 6 in one transition is determined depending on the thickness of the sheet 9, the size of the required thickening, as well as the material of the workpiece and is determined experimentally.

In the process of precipitation of the sheet blank 9 by the deforming roller 6, the material of the sheet blank 9 precipitates in the contact zone deforming the 4Q roller 6 with a gripping angle d, while the material of the sheet blank 9 moves, i.e. settles down, as it were, a little along a certain arc. Therefore, the retaining roller 5, setting g lennsh in the same plane as the deforming roller 6, immediately after the upsetting of the sheet stock 9 aligns the material in the zone of thickening and during each pass.

gQ deforming roller 6 rises

by the amount of thickening formed (thickness increment).

Rolling the edge of the sheet blank 9 is carried out in both directions gg, each time the deforming roller 6 is moved in the axial direction by the movement mechanism 7 by the value of h (the amount of draft) until a thickening with the specified parameters is obtained. After that, the deforming roller 6 and the retaining roller 5 are retracted to the initial position, release the sheet stock 9 and are removed from the base plate 1. As a result, sheet stock 9 is obtained with a thickening on the sheet edge. To obtain a bulge on the opposite edge, the latter is inverted, fixed again and the process is repeated. Since there is already a thickening on the opposite edge, on the pressure plate

In plate 3, it is necessary to make an additional displacement equal to the size of the resulting thickening.
