Stock lifter assembly
11267036 · 2022-03-08 · ·

A stock lifter for metal forming dies includes a self-contained assembly. The assembly includes a guide pin that reciprocates within a base. A hardened end cap, which contacts the stock, is attached to the guide pin. A spring is located on the exterior surface of a portion of the base and surrounds the guide pin body. One end of the spring contacts a surface on the cap, while the other end of the spring contacts a surface on the base or an optional mounting flange that is attached above the base. Thus, the stock lifter assembly has a hardened cap for the stock to slide on and a larger, externally mounted spring that provides longer life for the stock lifter. The stock lifter assembly can be made of several different lengths and sizes by using longer or wider guide pins and springs.

Powder press having a cone-shaped substructure

The invention relates to a powder press, comprising a tool structure, which has a conical substructure having lower rams nested in each other, wherein each lower ram has a longitudinal extent, in particular a cylindrical longitudinal extent, which is guided in a die, wherein, in the case of at least two longitudinal extents of the lower rams, each longitudinal extent is adjoined by a conical enlargement, wherein the conical enlargements can be guided in each other, wherein the region of the conical enlargement has an inner wall and an outer wall, which expand conically and which are preferably longer than the longitudinal extent. The invention further relates to a method for operating a powder press and to a computer program product having computer program code means that can be executed on a computer system in order to perform the method.

Powder compaction mold and method for manufacturing powder compact

A powder compaction mold includes a die and upper and lower punches configured to fit into the die and is configured to compress a powder between the upper and lower punches to manufacture a powder compact. Of the members forming the powder compaction mold, at least one of two members in sliding contact with each other has therein a vent passage through which gas is vented from a filling space for the powder surrounded by the die and the lower punch to an outside of the powder compaction mold. The vent passage has a gas intake port that is open to a clearance section formed between the two members and connecting to the filling space.

COLD COMPRESSION MOULD PROCESS AND APPARATUS
20210276295 · 2021-09-09 ·

The process immerses a plurality of smaller solids in a liquid softening/solvent/bonding agent (i.e. water, oils, solvent or some other combination). This reagent reacts with the solids over a period of time so that when the cavity containing the solid/liquid mixture is compressed, the solids and any other additives (i.e. oatmeal, spices, other foreign objects, etc . . . ) are forced together and force the liquid softening/solvent/bonding agent out. The expelled liquids are removed from the solids and additives which are then allowed to dry/bond/fuse thereby forming a solid bond. Whereas there is prior art utilizing aspects of this process specifically in soap scrap bonding, this method is the only method of compressing solids that does not require electricity and where the disparate solid pieces and the bonding agent/liquid are all contained in one vessel that enable the solids to react with the liquids and then be compressed removing the bonding agent/liquid and leaving only the solids which can then form a permanent bond, all in one device (see FIG. 8: Novel Mould Assembly , FIG. 10—Mould Assembly Option, FIG. 12—Novel Mould Assembly with Option Plunger Design). Furthermore, this design can incorporate the collection and if desired recycling of the reagent within the mould itself (i.e. a hollow cavity in the plunger and if necessary a collection vessel attached to the cap and/or stabilizing base). Finally, the plunger design allows the device to be used with or without any mechanical aids to prevent it from binding during longitudinal movement during compression of the mould/plunger. This, first of all, simplifies the mechanics of the device and allows the mould to be used by young and old alike regardless of ability.

This device will have applications in many industries but especially the craft industry (i.e. cheese making and soap making).
