Description

The invention relates to the processing of metals by pressure and can be used in all sectors of the economy

for stamping parts from lengthy

profile blanks elastic medium.

The purpose of the invention is to improve the reliability, durability, safety and expansion of technological capabilities.

FIG. 1 shows the installation of hydraulic presses for stamping long parts with elastic medium, general view; in fig. 2 - section A — A in FIG. 1, installation in the initial position; in fig. 3 - the same installation in the working position.

The interlocked installation of hydraulic presses for stamping long parts with elastic medium contains at least two presses 1 and 2, on the rods 3 and 4 of which the top plate 5 is fixed with a universal container 6, whose working chamber is equipped with an elastic pillow 7. The forming mandrel 8 is mounted on the bottom the plate 9. The grip side (long) walls of the working chamber bracket 10, based on the return spring 11 and 12 (Fig. 1 and 2) is installed in four guides 13 and 14 (in Fig. 1 two guides are shown) located between the station Aninah press. The return springs are fixed in guide sleeves 15. To ensure the required rigidity of the power circuit of the interlocked installation, the frame of the presses are connected by fastening walls 16 and 17 and the fastening beam 18. The frames of the presses are mounted on a common base 19.

Interlocked installation of hydraulic presses for stamping long parts with elastic medium works as follows.

The profile to be machined is installed in the groove of the forming mandrel 8 (FIG.

1 and 2). Under the action of the efforts of the presses 1 and 2, the container 6 moves down and enters the bracket 10 (Fig. 3). The increasing pressure of the elastic medium 7 acts on the processed profile and the walls of the working chamber. Under the action of increasing pressure of the elastic medium, the side walls of the working chamber deflect and grip them with the bracket 10. Further movement of the container 6 occurs together with the bracket 10, which moves in the guides 13 and 14 and compresses the return springs 11 and 12. After the stamping process is completed, the container 6 returns to its original position under the action of the efforts of the presses 1 and 2, and the bracket 10, moving in the guides 13 and 14, returns to its original position under the action of the return springs 11 and 12.

The proposed device allows you to prevent the destruction of the slit working chamber of the container from the action of cyclic loads from the elastic medium, to increase the reliability, durability and safety.

In addition, the proposed device allows stamping with a higher pressure of an elastic medium, which expands its technological capabilities to stamp lengthy parts of various complex configurations, for which it is necessary to change only the forming mandrel.

The durability of the working chamber of the proposed interlocked installation with a reinforcing bracket is more than 60 thousand cycles instead of 30 thousand from the known one.

The savings from the use of the proposed device in comparison with the base object in only one enterprise will be about 2000 rubles. in year.
