Definitions

  • the invention relates to a pressing device for pressing workpieces made of wood, plastic, metal and the like according to the preamble of claim 1.
  • pressing devices with which panels composed of lamellae are pressed with pressing tools against a base.
  • Such panels can consist of lamellae loosely fitted together or glued together. They are assembled edge to edge with layers of glue between them to form the panels.
  • the panels are pressed against a stop using a stamp and at the same time pressed onto the support with the pressing tool.
  • the invention is based on the object of designing the generic pressing device in such a way that reliable pressing of the workpieces is achieved in a structurally simple manner.
  • the pressing tool can be quickly adjusted into the pressing position or out of the pressing position into a starting position with the aid of the height adjustment device.
  • the pressure device with which the pressing pressure is generated, is dragged along. This enables the pressing tool to be adjusted quickly.
  • the pressure device is only actuated when the pressing tool rests on the workpieces to be pressed.
  • the height adjustment device has at least one piston-cylinder unit with a piston rod which is drive-connected to the pressing tool. With the piston rod, the pressing tool can be easily and quickly adjusted to the pressing position or moved back from the pressing position to the starting position.
  • the pressure device has at least one piston-cylinder unit, which has a piston rod that is drive-connected to the pressing tool. It is carried along when the pressing tool is adjusted by means of the height adjustment device.
  • the piston of the piston-cylinder unit of the pressure device advantageously separates two pressure chambers located on either side of the piston from one another.
  • the fluid or pressure medium used to pressurize the piston is displaced via a line during the height adjustment by means of the height adjustment device and thus during the entrainment process of the pressure device between the two pressure chambers of the piston-cylinder unit.
  • the two pressure chambers are not under pressure here, so that the piston rod and thus the piston can simply be taken along when the height of the pressing tool is adjusted.
  • One switching valve is switched in such a way that it connects the two pressure chambers on both sides of the piston with one another.
  • the other switching valve is switched in such a way that the pressure chamber, which is pressurized when the pressing tool is moved into the pressing position, is connected to the tank. Therefore, if the pressing tool is adjusted into the pressing position by means of the height adjustment device, the pressure chamber located in the front in the displacement direction can Pressure medium can be shifted over a switching valve in the other pressure chamber. Since its volume increases during the downward movement of the pressing tool, a negative pressure is created in this pressure chamber, which means that pressure medium is drawn in from the tank via the other open switching valve.
  • the pressing elements of the pressing tools are provided with fluid-filled elements so that a uniform distribution of pressure on the plate over its surface is achieved in the known pressing devices.
  • the uniform pressure distribution on the workpiece is advantageously achieved in that mechanical elements are used as pressure elements.
  • the pressure element located between the pressure plate and the plate carrier consists of a shaped body that can be compressed with limited elasticity.
  • the pressure element then behaves like a rigid body during the pressing process.
  • the material of the pressure element has a modulus of elasticity that is smaller than the modulus of elasticity of the workpiece. This ensures that the pressure generated by the pressing tool reaches the workpiece completely and that as little as possible is lost.
  • the pressure element is designed in the form of a plate and thus ensures that the required force is applied over the entire surface of the workpiece.
  • the pressure element which acts as a pressure compensation element, does not require an external pressure source, as is necessary with pressure hoses of conventional pressing devices.
  • the pressing device according to the invention has a very simple structure and can be manufactured particularly inexpensively.
  • the pressing device according to the invention works reliably and trouble-free.
  • the pressure element is advantageously formed by a porous material.
  • the pores in the material of the pressure element allow a limited elastic deformation, which has an advantageous effect on the even pressure distribution.
  • the strength of the pressure element increases after the pores have been compressed, so that very high pressures can also be exerted on the workpiece with the pressing tool.
  • a preferred material for the pressure element is cellular polyurethane. It is characterized in that it has a desired, relatively linear spring characteristic in a coordinated pressure range.
  • Suitable materials can be used for the pressure element depending on the pressure range of the pressing device and the spring characteristic or the e-modulus.
  • the pressure element advantageously has a constant thickness over its length and width. This ensures that the force can be transmitted evenly to the workpiece over the surface of the pressure element.
  • the pressing tool can have two or more pressure elements.
  • the pressure elements run parallel to one another at a distance.
  • narrow pressure elements are used, which can be easily manufactured and installed in the pressing tool.
  • the distance between the pressure elements is only so small that this distance does not lead to an uneven distribution of pressure on the workpiece.
  • Reliable pressure is applied to the workpieces if the press plate is made of metal, preferably steel.
  • the pressing device is provided with at least one alignment unit. It is used to align the workpieces again before the pressing process.
  • the alignment unit can be provided in such a way that it aligns the workpieces in their longitudinal direction or also transversely to their longitudinal direction.
  • the alignment unit can also be designed in such a way that it aligns the workpieces both in their longitudinal direction and transversely thereto.

  • the press tables 1 are fastened in a suitable manner on the inner sides of the side walls 8, 9 facing one another.
  • the press tables 1 are formed by individual sections that are connected to one another in abutting manner. In this way, the length of the press tables 1 can easily be adapted to the length of the pressure beams 3 or the press device.
  • the support 14 extends over the length and the total width of the two press tables 1, so that the slats 4 of the slat carpets 2 can rest cleanly on the press tables 1.
  • the support 14 is designed as a transport device, such as a transport chain.
  • At least two drives 15, 16 forming pressure devices are provided over the length of the pressure beam units 5, one behind the other at a distance.

  • the pressure cylinders 18 protrude upwards over the supports 17, so that an easy connection of the supply line for the respective energy medium is possible.
  • the pressure beam 3 has two connections 20 to which the piston rods 19 of the pressure cylinder 18 can be connected. By actuating the piston rods 19, the pressure bar 3 is adjusted in the vertical direction in order to carry out the pressing process or to cancel it again.
  • the length of the pressure bar 3 corresponds at least to the length of the slatted carpet 2 .
