Definitions
- the invention relates to a method for producing single-layer compacts from pulverulent substances by means of automatic presses, in which the powder is filled, pressed and ejected into a press tool in corresponding working positions within a press cycle.
- the invention has for its object to develop a method with which the quality of the molded parts, in particular with regard to weight tolerance and the length of the Cycle time can be significantly improved.
- This object is achieved according to the invention in that a multi-position automatic press is used and in that the press cycle is repeated at least once over one cycle.
- a multi-position press is by the DE-PS! 24 20 726 already known.
- the press cycle can be repeated over a cycle in accordance with the number of pressing tools used.
- Fig. 1 shows a schematic representation of the sequence of the method according to the invention in six parts on a multi-position press.
- the machine has two cycles.
- the first cycle consists of the filling process, which extends from F1A through F1 to F1E, the pressing process P1 and the ejecting process A1.
- the second press cycle consists of the filling process, which extends from F2A via F2 to F2E, the pressing process P2 and the ejection process A2.
- the filling process starts at F1A or F2A, with the press table moving clockwise according to direction arrow 1.
- the sub stamp of a filling die (not shown) (pressing tool) is moved downward over a cam plate, also not shown, so that powder can already flow into the filling space of the die.
- the press table stops and the filling process runs out slowly in order to achieve the smallest possible mass tolerance. Then the press table starts moving again. Excess powder is now wiped off the die using a scraper. The process is finished at F1E.
- the press table stops and the pressing process starts. The press table then moves in the A1 direction. The press table stops in this position and the finished compact is ejected.
- the press cycle described is repeated again. A total rotation of the press table corresponds to two press cycles with six standing positions.
- Fig. 2 shows a schematic representation of the sequence of the method on a multi-position press with four parts.
- the machine has two working cycles.
- the first cycle consists of the filling process, which extends from F1A through F1 to F1E, the pressing process P1 and the ejecting process A1.
- the second press cycle consists of the filling process, which extends from F2A via F2 to F2E, the pressing process P2 and the ejection process A2.
- the filling process starts at F1A and F2A, respectively, with the press table moving clockwise according to the direction arrow 1.
- the lower punch of a filling die (not shown) (pressing tool) is moved downwards via a cam plate, also not shown, so that powder can already flow into the filling space of the die.
- the press cycle can also be carried out three or more times via one revolution of the press table.
