SU12467A1 - Device for storing pressed powder for the purpose of subsequent pressing - Google Patents

Description

 . In order to obtain B finished products, pressed objects, for example, buttons, from a powdered material, are prepared by first sub-pressing the tablets, which are then shaped into a forming tool. However, light injuries of these sub-pressed tablets occur very often, especially if they are to be colored or ornamented. The addition of pills to the molding tool takes a lot of time. The present invention, which relates to devices for preserving the pressed powder for the purpose of subsequent compression, is intended to eliminate these drawbacks by using a frame that is thicker than the thickness of the layer of the pressed powder used for pressing the powder.

In the schematic drawing of FIG. Figure 1 shows a section of the press d. And prepressing) peas, phpg. 2-section of the frame with a pre-compressed tablet; FIG. 3-section of the molding tool with a frame inserted into it with a subpress tablet, FIG. The 4-mold tool of FIG. 3 in position after molding.

The D.5I press of the subpressing of the tablets (Fig. 1) consists of a body 1 with a piston 2.

forming a movable bottom plate, and EZ

the upper fixed plate 3. The adaptations, which are intended for actuation of the pore and the press plates, are not shown in the drawing, for such are generally known. A plate 4 is placed on the press housing 1, having an opening 5 into which poron-like material 6 is pressed into piston 2, so that pressed material is firmly held in opening 1 of PTA 4 and forms tablet-like tablet 1 (Fig. 2), which is less thick than the frame, which aims to protect the tablet from damage during processing and storage. The molding tool for making desired objects, such as buttons, can be of any design. It consists (Fig. 3 and 4) of two matrices - the lower 8 and the upper 9, between which the tablet 7 is inserted and the frame 7 is inserted. When the upper matrix 9 is lowered onto the lower 8, tablet 7 is molded, at which time frame 4 releases a tablet, sitting on the lower cat 8 under the action of some 9.1 element of the molding tool, for example, under the pressure of a font 10, fortified in the upper matrix 9. However, the tablet may remain in the I frame during the press.

The frame 4 may have any number of holes, in which case the molding tool must consist of the corresponding number of upper and lower dies in order to simultaneously compress all the tablets sitting in the frame 4.

In hot pressing, work is accelerated by tes1, which is made of light weight

metal, for example an electron, since in this case the best thermal interaction between the metal plate and the tab of the wire is obtained.

The subject of the patent. A device for preserving the press powder for the purpose of subsequent pressing, characterized by the use of frame 4 (Fig. 1-4), the thickness of which is greater than the thickness of the pre-pressed powder layer 7.
