摘要:
A temperature probe (1), particularly for thermoplastic mix extrusion machines, which comprises at least one casing (2), which is adapted to be inserted in an extrusion cylinder (4) substantially at right angles to the extrusion direction with one end thereof facing into the internal cavity (5) of the extrusion cylinder (4) so that it is in direct contact with the extrusion material contained in the internal cavity (5), and at least one thermocouple (3), which is accommodated in the casing (2) and is adapted to detect the temperature of the extrusion material by thermal conduction through the casing (2), the temperature probe (1) comprising thermally insulating means (6) which are interposed at least partially between the casing (2) and the extrusion cylinder (4) so as to reduce the thermal influence of the extrusion cylinder (4) on the measurement made by the thermocouple (3).
摘要:
An extrusion machine (1) with improved structure, comprising an internally hollow extrusion cylinder (2), at least one heating element associated with the extrusion cylinder (2), at least one cooling fan (30-39) which engages the outer surface of the extrusion cylinder (2), and at least one temperature probe (3) which is inserted in the extrusion cylinder (2), the temperature probe (3) facing the cavity (4) of the extrusion cylinder (2) and the temperature probe (3) being adapted to be in direct contact with the extrusion material contained in the cavity (4) of the extrusion cylinder (2).
摘要:
A wet wire drawing machine (la, 1 b), particularly for drawing very high strength steel wires, comprising: • - a station (2) for unwinding a coil of crude wire (3) from a rotating spool (200), • - a plurality of intermediate drawing stations (4, 5, 6) which are arranged sequentially with respect to each other and are provided with means (7) for the lubrication of at least the drawplates (8) with which they are provided, • - anti-slip pulling means (18) which are associated with the last intermediate wire drawing station (6) for the elimination of irregularities in the wire (19) processed in the intermediate wire drawing stations (4, 5, 6) and for attenuation of the vibrations of the rotating elements of the intermediate wire drawing stations (4, 5, 6), • - a final wire drawing station (24) which is provided with wire straightening means (25) so as to obtain a processed wire (19) having the desired geometric shape and mechanical characteristics, • - a coil winder (33) arranged in output with respect to the final wire drawing station (24) so as to wind the processed wire (19) into a coil (34).
摘要:
An apparatus (1) for cleaning, by abrasion, rod and the like with scale crust and surface oxide, that comprises, on a supporting frame (2), an assembly (3) for unwinding a wire or rod (F), on the surface of which a first abrasive cloth supporting spindle (20) and a second abrasive cloth supporting spindle (21) act; the first and second spindles (20, 21) are accommodated within a work zone defined by the supporting frame (2); the first and second spindles (20, 21) are directed toward each other and they are mutually and integrally joined to each other.
