A hot-press device includes: a heating furnace; a pair of punches which includes an upper punch and a lower punch provided in the heating furnace and vertically facing each other; a lower press ram which is connected to a lower surface of the lower punch; an upper press ram which is connected to an upper surface of the upper punch; and a pressing device which is connected to any one or both of the lower press ram and the upper press ram and presses the punch so that the pair of punches are close to each other, in which the lower press ram and/or the upper press ram includes a plurality of individual press rams which are disposed at intervals, each individual press ram having one end coupled to the pair of punches.

The present disclosure provides a pressing device which includes: at least two floating heads which are arranged side by side; a positioning member connecting with each floating head and defining a position of each floating head; a cover plate positioned above each floating head; and elastic members, each elastic member being provided between the cover plate and the corresponding floating head so as to make the cover plate slide up and down relative to each floating head. The pressing device can be adapted to a step type cell or a step type battery having a certain tolerance in thickness and can ensure that every step surface of the step type cell or the step type battery is uniformly pressed, thereby improving the quality of the battery.

A hydraulic powered press for hand tool repair is mounted to a wall and powered by an electric motor. A plurality of adjustable holders is secured about the side frame of the jack.

A punch system or assembly includes a punch body and a punch tip or insert with a working end and a stem configured for selective engagement and disengagement within a cavity in the punch body. A latch mechanism which can be operated without tools is configured to engage the punch tip stem within the axial cavity in a closed position, and to disengage the punch tip from the punch body in an open position.

An automated tablet tooling inspection system (100) for inspecting defects in tablet tooling's including upper punch, lower punch and die. The system (100) comprising of a base plate (101), a punch holder (102), a punch stopper (103), a die holder (104), a LM rail and carriage assembly (105), a LED Micrometer (107) to measure parameters of said tablet tooling, a Laser sensor or con focal sensor (108) to measure parameters of said tablet tooling and a control unit. The automated tooling inspection and system (100) reduces the inspection time of said tablet tooling by minimizing manual intervention; wherein said manual intervention is reduced by eliminating the requirement of changing configuration of said system (100) when a different type of tablet tooling is inspected such as TSM/Euro, B, D, BD, BB and BBS and the like.

A watch assembly method includes: processing a first bonding surface on a first connecting member, bonding a first laser adhesive layer on the first bonding surface and activating the first laser adhesive layer; processing a second bonding surface on a second connecting member, bonding a second laser adhesive layer on the second bonding surface and activating the second laser adhesive layer; fixing the second connecting member with the first connecting member preliminarily in such a manner that the first laser adhesive layer and the second laser adhesive layer face each other, and pressing the first connecting member and the second connecting member against each other until the first laser adhesive layer and the second laser adhesive layer are completely bonded and infiltrated.

A tablet punch. The tablet punch comprises an elongate fastener having a longitudinal extent, one or more punch components, each punch component having a longitudinal extent and being arranged to receive the elongate fastener, and a head component. The head component, configured to connect the tablet punch to a tablet compression machine, is arranged to receive the one or more punch components and the elongate fastener such that the elongate fastener fixedly connects the one or more punch components and the head component together. When the elongate fastener fixedly connects the head component and the one or more punch components together, the longitudinal extent of the elongate fastener is orientated substantially orthogonally relative to the longitudinal extent of the one or more punch components.

A tool and die set and related method of use of the tool and die set in a press for the compaction of a powder metal into a preform involves an uneven amount of positional deflection of at least two lower or upper tool members. This asymmetrical elastic response under load may help to eliminate cracking of the part after the compressive load is removed.

Disclosed is a method for producing a metal or ceramic component having regions of differing porosities. The method includes subjecting powder or a presintered precursor to a pressure-assisted pressing and sintering step, using at least one punch for the pressing step. The at least one punch has a contact surface that is intended for making contact with the powder or the presintered precursor and that has a flat outer region and an inner region having a concave recess. After the sintering step, a component is obtained that has a flat outer compacted region having a first porosity and an inner porous region having a second porosity. The component has, on at least one side, a defined transition region between the outer region and the inner region.

A press device for manufacturing compacted tablets from at least one mixture in powder form, including at least one compaction assembly including a lower punch and an upper punch each having an active compaction surface and placed on either side of a die. The lower punch has a longitudinal recess open on the side of the die, inside of which is mounted a central rod which is translatably mobile relative to the lower punch. The central rod is coupled to the lower punch by a resilient link provided so as to hold, in an inoperative position, the central rod in a maximum deployed position in which the central rod protrudes relative to the active surface of the lower punch. The invention also relates to a specific compaction method and to a multi-layer compacted tablet with a recess.
