Definitions

  • the present specification refers to a machine for engraving reliefs on the surface of hides or other materials in general, the obvious purpose of which is to be configured as a machine capable of engraving different shapes and reliefs on the surface of a hide or other materials, which, before being incorporated into the machine in question, have been properly treated, the surface of the hide exhibiting a coating formed by different products, which, once incorporated into the machine and this operates, exhibit shapes totally different to the original hide before being treated.
  • This invention applies to the industry dedicated to the treatment of hides and skins or other materials in general, having a later application in the footwear and morocco leather articles and the manufacture of products based on skins or hides.
  • the machine for engraving reliefs on the surface of hides in general as proposed by the invention constitutes per se an evi-solution to the present problems on this matter, since, starting from same and after an appropiate treatment of the hide by using adequate processes, the resultant product can be utilized in different applications, being strengthened and capable of being utilized for manufacturing different articles that, without the action of the machine, they could not be used.
  • the machine for engraving reliefs on the surface of hides in general is constituted starting from the utilization of a high frequency generator with a useful power of 300 kW, which can be utilized totally or in part; the machine being also fitted with a hermetic press with a closing force of maximum 300 metric tons.
  • the invention contemplates to utilize a set of two automatic trays, a water/water heatexchanger to refrigerate the high frequency generator, and a second water/water heatexchanger in order to refrigerate the moulds.
  • the invention contemplates the existence of a supporting hydraulic station.
  • this machine must rely on an adequate electric connection, and, optionally, it is recommended that the plant relies on a 100 amp. automatic switch, fitted with an adjustable thermal relay and a series fuse with an adequate capacity.
  • the plant must rely on a water connection to cool the generator heatexchanger to have at least 150 liter/minute at a 3.5 bar pressure and a maximum temperature of 35 o C, and it is recommended to install a cooling tower fitted with an adequate pump with a capacity sufficient for efficiently dissipating 150,000 Kcal/hour with this flow.
  • the water connection for refrigerating the heatex- changer of tables must rely on an adequate capacity, which must not be less that 75 l/min at 3.5 bar pressure and a maximum temperature of 25 o C, and it is recommended to equip the installation with a compressor unit fitted with a corresponding pump, this unit being capable of efficiently dissipating 75,000 Kcal/h with this flow.
  • the plant is fitted with six oleohydraulic cylinders of 200 mm diameter each and 100 mm stroke, working at a pressure of 150 bars.
  • the machine installation counts on two additional cylinders of 80 mm diameter, and a stroke of 150 mm, to achieve the displacements.
  • the pressure must come from a hydraulic station, the pressure of which being adjustable, put on the press.
  • the generator must work at 12 kW and 37 amp, d/c, being inexcusably and adequately protected according to the machinery security standards.
  • the hide is firmly held against the mould by means of an adjustable force between 30 and 300 metric tons.
  • Fig. 1 shows a block diagram of the subject of the invention, related to a machine for engraving reliefs on the surface of hides in general.
  • Fig. 2 shows a side elevational view, duly sectioned, of the trays, one of them carrying a silicone mould, and the other one carrying the hide to be later submitted to the relative engraving treatment.
  • the machine for engraving reliefs on the surface of hides in general is constituted starting from a piece of furniture (1), provided with an electric connection and a 1000 amp.
  • automatic switch (2) fitted with an appropiate adjustable thermal relay , as well as the corresponding fuses.
  • the wiring will be always in accordance with the rated voltages, and the electric connection will be located on the floor at a height never less than 2.5 m.
  • the machine has a heatexchanger (3) for strays and tables, and a generator exchanger (4), as well as the corresponding water connections (8) and (9) for the generator and tables, respectively.
  • the invention contemplates an air connection (10).
  • the machine has two trays (5) and (6) and a high frequency airtight press (7).
  • the hide or skin (12) is placed on the upper part of the tray (6), while the silicone mould (11) is placed on the lower part of the tray (5); once the hides or skins are located on the tray the pressing operation is performed, the hide or skin receiving the relief delimited by the mould (11), and after a pre-established time, the upper part is lifted about 700 mm when each cycle is ended in order to allow the treated hide or skin to be unloaded and to load then the following hide or skin to be treated.
