The invention relates to the processing of metals by pressure, in particular, to the design of dies, and can be used for hot bulk forming of cylindrical forgings with blind cavities in the ends.

The aim of the invention is to improve the performance of the stamp.

Figure 1 shows a stamp, longitudinal section; Figure 2 is the same cross-section.

The stamp for hot forging includes top 1 and bottom 2 plates- 11.1. In the grooves of the bottom plate 2, with the possibility of moving, the matrix 3 slides with the stream 4 are fixed on the connecting surfaces of the slant 5, made at an angle to the plane of the small plate, and in the slots of the lower plate, perpendicular to the slider matrices 3 with the ability to move secured crawlers - Ki 6 with punches 7. At the sliders b, the bevels 8 are made at an angle to the axis of the punches 7. On the upper plate 1, the wedge 9 is fixed with the bevels 10, interacting with the bevels of 5 matrix slider .3, with vertical sections 11 interacting with the faces of the 12 slider matrices 3, and with bevels 13, interacting with bevels of 8 sliders 6. In the sliders of matrix 3, 14 are placed with pushers 15, which abut against sliders 6 with poins 7. In the lower part of the sliders of Matrix 3 perpendicular to the MjX plane The arms are arranged with rods 16c springs 17.

The stamp works as follows.

A blank (not shown) is placed between the sliders of the matrix 3. When the press (not shown) is turned on, the top plate 1 with wedge 9 is moved to the bottom. The bevels 10 of the wedge 9 interact with the bevels 5 of the sliders of the matrix 3 and move the sliders of the matrix 3 in the directions towards each other until the brook 4 is closed around the workpiece. After that, with further movement of the wedge 9 downwards due to the interaction of the matrix 3 slides with the wedge 9 along the surfaces of the sections II and the faces 12, the stream 4 remains in a closed position, and the bevels 13 interact with the slides 8 of the slider 6 and move the slider 6

to the workpiece. Moving the sliders 6 causes the insertion of the punches 7 into the workpiece and the formation of deaf cavities at the ends of the workpiece.

After this, the top plate 1 is moved upwards. The sliders 6, under the action of the springs I4 and the pushers 15, when sliding the bevels 8 and 13 against each other, are moved apart, and the punches 7 release the workpiece.

Upon further upward movement of the plate 1 and the wedge 9 under the action of the springs 17 and the relative movement of the bevels 5 and the bevels 10, the slider of the dies 3 are dispersed, and opened from the stream 4 releases the workpiece. Thereafter, the preform is removed from the die and the punching cycle is completed.

Claims (1)

Invention Formula A stamp for a hot bulk punch containing an upper and lower plate, a composite matrix, two punches, and a die closing mechanism, characterized in that it is equipped with sliders with vertical edges and bevels located on the lower edge to increase productivity. the plate is movable, the punches are fixed on the above-mentioned crawls, both parts of the matrix are also made in the form of sliders with bevels and are placed on the bottom plate with the possibility of moving in the direction perpendicular to the direction of movement along pushes, the die closure mechanism is made in the form of a wedge with two pairs of internal bevels and vertical sections and is installed on the top plate with the ability of its pairs of bevels to interact with the punches and matrix bevels, as well as the said vertical sections — with edges of the matrix slides, The matrix sliders are equipped with spring-loaded pushers installed with the possibility of interaction with the sliders of the punches, as well as spring-loaded rods placed in the sliders on the side of the bottom plate and lennymi to cooperate with the latter. ifutZ Editor L.Povkhan Compiled by V.
