Description

The invention relates to the field of powder metallurgy to equipment for the treatment of powder blanks with high-pressure fluid. The most effective OMO can be used to create gas-stats for the treatment of powder blanks with high-pressure gas and high temperature gas.

The aim of the invention is to simplify the construction of reducing the size and reducing the metal intensity of the isostat.

Figure 1 schematically depicts an isostat with statics, displaced to a nor position. Loading and unloading of the workpiece; figure 2 - isostat with a statin, pulled down on the container; on fig.Z - section aa on fig.Z; Figures 4 to 7 show various positions of the frame with the unit for loading and unloading blanks.

The isostat contains a movable power base 1, hermetically sealed at the ends with plugs 2 and 3 fixed container A and a unit for loading and unloading blanks with clamps 5 of the lower stopper 3. It is equipped with a frame 6 and a drive 7 for moving it in {vertical direction to 8, fixed on the bed 1.,

The loading and unloading unit of the workpieces is made in the form of a drive 7 for moving the frame 6, rigidly mounted on the frame of the guides 8 and protruding in the direction of movement of the frame of the support 9, on which the fixings 5 of the lower stopper 3 are mounted. .

The vertical guides 8 comprise brackets 11 which are fastened.

to the frame 1. To the brackets I1, with the help of covers I2, screws 13, washers 14 and split rings 15, shafts 16 are fastened with eccentric wheels 17, On shafts 16, bearings 20 are fastened with nuts I8 and sleeves 19, on which rollers 21 are fitted Shafts 16 with eccentrics 17 allow you to adjust the distance between the rollers 2I. Container-A is installed on the table 22.

Isostat works as follows.

In the loading-unloading position (see Fig. 4), the movable power frame is installed coaxially with the container 4. Frame 6 is raised to the upper position. On the support 9, the latches 5 fix the bottom stopper 3. Place the workpiece 23 on the stopper 3. Then the frame 6 is lowered by the drive 7 into the lower position. Bearings 20 with rollers 2 provide movement of frame 6 along the pressure 8. Base frame 1 is relocated to a position where the cork 3 and support 9 is coaxial with the container 4 (see figure 5). Then driven

7 raise the frame 6 along the guides

8 and insert the stopper 3 with the blank 23 into the container 4 (see Fig. 6). Vyagod t clamps 5 from the bottom of the tube 3 and move the frame 1 to the position in which it is coaxial with the container 4 (see Fig. 7). Raise the pressure of the current medium in the container 4 from the source (not shown). At the end of the treatment cycle, the pressure in the container 4 is reduced to atmospheric and the listed operations are repeated in the reverse order.
