Definitions
- the invention relates to a method for three-dimensional forming of sheet material, in particular natural fibers, such. Paper or cardboard, with a piston and a box-shaped opposite, into which the material is drawn.
- the invention has for its object to propose a forming process with which this uncontrolled wrinkling is avoided.
- a forming process with which this uncontrolled wrinkling is avoided.
- thermoforming result This further improves the thermoforming result.
- wrinkle distribution can be further improved.
- spring-loaded against the sheet material can press and / or acting against the sheet material pressure of the pleat holder can be controlled or regulated.
- the diameter of the die is variable.
- the diameter of the die can also be deep-drawn conical.
- the diameter is not limited to circular deep drawing. Rather, all conceivable forms are possible. This includes just circular, oval, polygonal, square, etc.
- the die is constructed of segments that are movable relative to each other. As a result, the diameter can be changed in a simple manner.
- thermoforming piston is conical.
- thermoforming piston is variable in terms of its diameter, wherein segments may be provided which are mutually movable.
- thermoforming piston with variable diameter can be used very well in a conical die.
- One possibility for modifying the diameter of the deep-drawing piston is a construction of mutually adjustable segments.
- thermoforming piston is changeable by internal pressure in its shape and / or its dimensions, wherein the pressure can be established by means of compressed air or a hydraulic medium.
- Such a deep-drawing piston can be used both in a conical Martrize and in a variable diameter die. According to the invention, it has also proven to be very advantageous if in the axial direction to Tiefziehkolben a counter punch is provided, which presses the material during the forming against the deep-drawing piston, wherein the counter punch can be made variable and adjustable.
- the material is reliably guided during forming, so that no uncontrolled movements of the material can occur.
- the holding force can be set very accurately.
- a calibration device in which the formed material is pressed against the piston.
- the resulting small wrinkles during forming can be equalized in a simple manner.
- Embodiment of the invention the material before, during and / or moistened after forming and / or calibration at least on one side.
- the material is heated before, during and / or after the forming and / or before and / or during the calibration.
- the temperature and / or the processing moisture of the material is selected or adjusted depending on the material used.
- a further advantageous embodiment of the invention is that the material is or will be provided at least on one side with a plastic layer.
- the fibrous material is effectively protected against internal and / or external influences.
- the open end is transferred to a sealing edge.
- the created container can be closed after its filling in a simple manner.
- the sealing edge is additionally compacted, wherein the densification can take place with the supply of heat and / or after previous moistening.
- Fig. 1 is a schematic representation of the sequence of the invention
- Fig. 2 is a schematic representation of the process of the invention
- 1 denotes a device with which paper or cardboard or fiber-containing material 2 can be converted from a flat state into a cup or dish-shaped state.
- the device 1 has a piston 3, as well as a conical in this exemplary embodiment bush-shaped die 4, which acts as the opposite of the piston 3.
- the material 2 is pressed by the piston 3 in the die 4.
- the material 2 is pressed by a fold holder 5 against the top of the die 4, so that it can only slip in controlled when entering the die 4.
- the piston 3 is formed variable. Either this is composed of segments, so that the respective diameter of the piston 3 can be changed by moving the segments to each other, or the piston 3 is changed by application of compressed air or a hydraulic medium in size and / or shape.
- the diameter of the piston 3 at any time at least approximately corresponding to the respective diameter of the die 4 minus twice the thickness of the material 2, so that the piston 3, the material 2 and the die 4 closely abut each other. There should be at most a small gap. But it is also conceivable that the piston 3, the material 2 pressed slightly against the inside of the die 4.
- the fold holder 5 ensures that not only small and evenly distributed wrinkles during thermoforming of the material 2 arise, but these are at least largely equalized. If the piston 3 is slightly smaller with respect to the die 4, then it is also conceivable that the manufactured article 7, the formed part, is calibrated again after the forming process and the finely distributed wrinkles are pressed.
- the result is a smooth surface in the walls of the paper or cardboard deep drawn article.
- a conical piston 23 is provided, and the die 24 adapts its diameter to the respective position of the piston 23.
- the die 24 can for example be moved against each other
- the fold holder can spring loaded against the sheet material 2 press. But it is also possible a hydraulic, electromechanical or otherwise
- control or is configured adjustable.
- a combination between spring load and controlled or regulated hydraulic / pneumatic / actuators is also conceivable.
- the material 2 in the bottom region between the piston 3 and the counter punch 6 itself is transformed.
- the embossing takes place by the piston 3 and the counter punch 6 before the actual forming process.
- the piston 3 and counter punch 6 can already close under Faltenhalterkraft and bring in the embossing. In this case, a drawing operation is made against the actual pulling forming, whereby the scope in terms
- Calibrator 8 moves from the piston 3, where the wall portion is pressed against the piston 3 and thereby the small and finely divided wrinkles formed are equalized.
- gravity can also cause the generated articles 7 to fall out.
- the top wall area can be widened or an edge flange formed.
- This edge flange can be transferred either into a flat sealing edge or into a mouth roll.
- the material 2 can be moistened before or during this process one or both sides.
- a heating is possible, with a radiant heater for the material or heating of the forming tools is conceivable.
- a coating, impregnation or other treatment of the material, for example with a plastic is also possible to improve the tightness of the finished part 7, wherein this coating can be made inside or outside or on both sides.
- a coating or treatment can also influence the deep-drawing process.
