DUNKES - Powder Presses / Massive Forming

pv160-dun45-pm-hydclamp

DUNKES에 분말금속 프레스는 정밀한 RAM control을 통하여 성형과정의 반복 정밀도가 매우 높음. 상부/하부 피스톤이 비례 제어 되는 ram control임

 

The DUNKES powder presses are used for the manufacture of formed parts from powder / granulates. Either 2 - or 4- column frames or frigid frames are used. Extremely accurate ram control (round or eight fold flat) in conjunction with proportional control for the upper and lower pistons ensure very high reproducible accuracy for the moulding process.

DUKES 분말금속 프레스에 있어서, 상하 피스톤의 편차는 ± 0.1 mm 이내임. 분말프레스에는 부속장치 및 기능은 분말 Filling station, 유압식 금형 clamping 장치, press cycle 스타트는 light-barrier에 의하여 시동되는 것 등을 포함함. 이러한 모든 요소가 CNC 또는 PC 컨트롤됨. 금형교환은, Filling 장치를 해체하지 않고 할 수 있으며, 타 기계에 비하여 매우 짧은 시간에 행할 수 있음. 분말에 filling 높이는 CNC 프로그램에 의하여 프로그래밍됨. Filling이 끝나면 자동으로 skimming이 이루어짐. 제품 (부품)의 높이는 프레스 사이클이 끝날 때 마다 매번 자동으로 재조정 되는 기능이 있어서, 계속적으로 다음번 사이클에 도움을 줌. 이것은 지능적이고 자기 수정기능을 갖는 것이며, 이로써 일관성 있는 제품 품질을 유지함.

The deviation of upper and lower pistons is, related to the stroke, approx. ± 0.1 mm! CNC or PC control technology are used to program and store all necessary data. Additional components for a powder press such as the filling station for the granulates, hydraulic tool clamping, or activating the pressing start by means of a light-barrier, provide further ways of reducing cycle or down times. The feed shoe at the rear of the press is integrated in the press process control. When changing tools, this feed shoe moves automatically. This means that a tool change can be carried out in a relatively short time without disassembling the filling device. The filling height of the powder/granulates is programmed using the CNC control. After filling, the mould is automatically skimmed off using specially developed software. This means that skimming can take place without any additional compression of the powder/granulates in the mould. The thickness of the pressed parts is controlled after the pressing process by an automatic readjustment of the filling height, which is incorporated in the next pressing cycle. Needless to say, there is an intelligent, self-correcting control which guarantees a consistent product quality.

Massive Forming

 

철판소재의 뎁드로잉 기술외, DUNKES는 Extrusion technology를 이용하여 고정밀 부품을 성형하는 기술을 보유하고 있음. 이 기술을 통하여 제품의 경도 (work- hardening)를 50%까지 증가 시킬 수 있음. 이 방식은 기계 절삭 가공보다 경제적인 방법임.

As an alternative to the deep-drawing technology of sheet metal there is also the possibility of manufacturing high precision parts using extrusion technology, e.g out of close-to-end-shape aluminum. Using this technique there is a work-hardening of up to 50% cal than machining, and less material is required. The DUNKES range of presses offers specially for this technology hydraulic presses which possess the necessary characteristics such as optimum frame rigidity, hydraulic knuckle-out axis in table and ram, as well as oversized eight-fold controlled ram for high precision. Programming is carried out by means of the various types of DUNKES control systems. Together with associated manufacturers of tools and of the method of forward/backward extrusion we can supply you with all necessary know-how and a complete package.
