Definitions

  • the invention relates to a block forming machine and a method for height adjustment of a block forming machine.
  • Stone forming machines are known in various embodiments in the prior art. Essentially, it is a matter of providing a mold in a clocked process, of filling a concrete quantity into the mold cavities of the mold, of compacting the concrete quantity with a stamp and / or a vibrating device and then demoulding the moldings.
  • a stamp and / or a vibrating device When it has proven useful to insert underlay pallets in the stone forming machine and lower downwards and downwards open forms on the underlay palettes.
  • the concrete quantity is filled from a concrete bunker into a filling car and let into the mold from the filling car. Subsequently, the concrete is compacted with a vibrating device and with a punch pressing on the concrete. In the next step, the punch and the mold are raised and the base pallet with the moldings is removed from the stone forming machine.
  • Stone forming machines can be used to produce differently shaped stones. These may differ in height, in particular. For example, concrete slabs have a height of approx. 30 mm, while curbs may have a height of approx. 300 mm. In order to produce stones with different heights, the stone forming machine must be adjustable. Conventional stone forming machines have a main frame, inside which a height-adjustable subframe is arranged. For height adjustment spindle drives are usually provided. These can be turned by hand or with electric motors to the desired height. It has been shown that the spindle drives allow a very accurate adjustment. A disadvantage, however, is considered that the adjustment of the height is associated with a high workload, because the subframe in the main frame after a height adjustment must be adjusted consuming. In addition, the height adjustment with spindle drives is slow.
  • the block making machine has a bearing block and a main frame which can be fixed in height adjustable manner on the bearing block, wherein, in particular, at least one mold lifting device for raising and lowering a stone mold is provided on the main frame.
  • the main frame is movable relative to the bearing block by actuation of the supported on the bearing block Formhubvoriques, in particular raised or lowered.
  • the bearing block may be an arbitrarily designed support structure, such as a frame, a subframe or the like, or a foundation.
  • the Formhubvoriques comprises at least one Formhubzylinder and / or a form of traverse. Due to the mold cross-member, the device is stabilized so that lifting with only one lifting cylinder is possible. Also, a wider shape can be used. With a mold lifting cylinder, not only are higher molds NEN larger stroke quickly be moved, but according to the invention, the entire machine.
  • the Formhubvorraum is supported over at least one Abdschreibklotz relative to the bearing block.
  • the use of an ejector block ensures that the former and the pedestal do not come into direct contact. This is advantageous, on the one hand to provide the largest possible stroke of the mold lifting device for normal production operation and on the other hand, the stroke of the molding device need not be extended in addition to provide the lifting function for the main frame of the machine.
  • the Abdschreibklotz is only used in the stone forming machine when a height adjustment of the main frame is to take place.
  • At least one coupled to the bearing block and the main frame shape guide rod can be provided.
  • the shape guide rod has the task to guide the Formhubvorraum. In this way it is ensured that the orientation of the Formhubvortechnik is always the same. This is particularly advantageous when multiple Formhubzylinder be used, since they can not be operated as uniform in the rule, as would be necessary for a uniform lifting of the stone forming machine.
  • the mold lifting device is fixed to the mold guide rod.
  • the shape guide rod is then mounted on floating bearing on the main frame or on the bearing block. It has been found that a Formhubvorraum fixed to the mold guide rods is not tilted.
  • a punch lifting device for raising and lowering at least one punch can be provided on the main frame.
  • the punch lifting device comprises at least one punch lifting cylinder and / or a stamping crosshead.
  • At least one of the bearing block and the main frame coupled punch guide rod is provided.
  • the purpose of the punch guide rod is to keep the punch lifting device and the punch attached to the punch lifting device in a constant orientation regardless of the stroke position. In this way, a uniform contact pressure over the entire stamp support surface is achieved.
  • the punch lifting device is also fixed to the punch guide rod.
  • the punch guide rod is then mounted on floating bearing on the main frame or on the bearing block. It has been found that a stamp lift device tion, which is moved like a carriage along stationary punch guide rods, due to the high-acting forces and the partially uneven force introduction tends to tilt. This is prevented by the attachment of the Stempelhubvorraum to the punch guide rod.
  • the Formhubvorraum is coupled to the punch guide rod and / or the Stempelhubvorides is coupled to the mold guide rod. This mutual coupling increases the precision of alignment even with a particularly high force input. The arrangement is also space-saving.
  • mold guide rods and punch guide rods may be provided parallel to each other, wherein the mold guide rods are arranged diagonally opposite one another.
  • This arrangement in which the mold guide rods and the punch guide rods define edges of an imaginary cuboid, makes it possible to guide the stamp and / or the mold in a space-saving arrangement particularly stable against tilting.
  • the mold guide rod and / or the punch guide rod can be guided by at least one guide unit in the bearing block and / or in the main frame.
  • the guide unit is a floating bearing. In the guide unit, a guide rod is guided with high precision at low friction.
  • the block making machine has a main frame which can be fixed in height adjustable manner by at least one main frame locking unit on the bearing block.
  • the main frame relative to the bearing block can be lowered by loosening the Hauptrahmenfeststellü.
  • the advantage of this solution is the fact that the lowering can be done very quickly because the main frame no longer needs to be cranked down spindle drives.
  • the Formhubvorraum can be used.
  • the mold lifting device Before releasing the locking unit, the mold lifting device can be moved so that it is supported on the bearing block. This makes it possible to lower the main frame in a controlled manner by releasing the locking unit by retracting the lifting cylinder. If the main frame is at the desired height, this height can be fixed by tightening the locking unit.
  • the main frame on at least one longitudinal guide element such as a mandrel or a shaft
  • the bearing block with the locking unit can be fixed.
  • the mandrel has a double function here. First, it ensures accurate alignment of the main frame in the horizontal plane. On the other hand, it allows a precise height adjustment of the main frame.
  • the method according to the invention for height adjustment of a block making machine comprises the steps of the method of a forming device in a position supported on a bearing block; solving a main frame detecting unit for a main frame; operating the mold lift device such that the main frame is raised; and tightening the main frame detecting unit for the main frame.
