Abstract

CO / 1 BINDED STA / Vin for machining forgings, mainly complete ones, containing upper drive and lower fixed plates with respectively upper tool mounted on them, with sections for // 2 straightening and trimming of forgings, and lower tool in the form of a cut matrix, different that, in order to expand the range of the products obtained and increase the reliability of the stamp, it is provided with a support placed under the bottom plate under the workpiece with a working surface on the end of the upper plate, mat ICA is fixed relative to said support with an annular gap, the stamp is provided with radially placed knives in the gap facing the working portions to the top plate and the upper tool is formed as a single unit, which portions for straightening and cutting are alternately arranged from the center to the periphery of the order.

Description

The invention relates to the processing of metals by pressure, specifically to the hot forging of complete forgings.

The purpose of the invention is to expand the range of products obtained and increase the reliability of the stamp.

FIG. Figure 1 shows a stamp in the position before trimming the scrap (left part) and a stamp in the position after trimming the scrap, separation of the forging and straightening of the divided parts of the forging (right part); in fig. 2 shows section A-A in FIG. 1, an embodiment of knives for cutting the wallpaper ring; in fig. 3 - the same, the embodiment of knives for cutting the overlapped ring.

The stamp consists of an upper tool 1 with straightening areas 2, 3 and trimming 4, a matrix 5 with adjusting elements on the outer surface, a support 6 for a blank workpiece for cutting knives around 7. The support 6 is placed on the support 8 connected to the housing 9 and bottom plate 10. Stamp

also contains the top plate And, the clamping ring 12, fasteners 13-15. The stamp works in the following way. After placing a complete forging in the stamp consisting of an outer forging 16, a cladding ring 17 and a central forging 18, the die 5 and the support 6 are affected by the upper tool 1 on the forging, and its trimming section 4 cuts the cladding ring 17

knives 7 (fig. 1, half right). After the cut-off ring has been cut, the sections 2 and 3 press the forgings 16 and 18 against the support 6 and the matrix 5, the rod 6, and thus both of the combined forgings are straightened. After that, both forgings are removed from the punch, and the cover ring remains on the blades 7.

The next forging is machined in the same sequence, only the cladding ring at this time lays on the previous one and pushes it downward, cutting it into pieces, and these parts will fall into the team tank, which is substituted at the bottom (not shown).
