Abstract:
A machine for driving inserts into pieces of sheet metal includes a punch (50) and a die (46) movable relative to one another along an axis (A) along which the inserts are to be driven. The punch (50) and die (46) define a driving zone (52) therebetween, in which a hole (144) in the piece (22) in which an insert is to be driven is positioned. The axis (A) along which the inserts are to be driven is substantially horizontal and the pieces are held in a substantially vertical plane by an automatic handling device (26).
Abstract:
The system for producing bent sheet-metal articles comprises a bending machine (80) having a punch (84) and a die (86) which cooperate with each other and define a bending space, and a manipulator (64) having a movable head (76) which can grip a piece of sheet metal and place it in the bending space. Each piece to be bent has its own gripper and the head (76) of the manipulator (64) has rapid-attachment means for gripping and releasing the gripper associated with each piece. A table for defining the position of a piece to be bent, a manipulator for gripping and moving a piece of sheet metal by means of a floating head, a bending machine comprising an auxiliary structure for measuring the relative displacement of the punch and the die, and a device for automatically replacing tools of the bending machine are also described.
Abstract:
A liquid filter device (1) for use in water plants, comprising: a chamber (2); a filter cartridge (3) arranged internally of the chamber (2), comprising a wall (4) provided with openings (5) for filtering a liquid; scraping means (6); a liquid outlet (7); the filter cartridge (3) and the scraping means (6) being reciprocally arranged and mobile in such a way that the scraping means (6) can scrape the wall (4) of the filter cartridge (3) in order to remove material deposited thereon. Further, the chamber (2) is arranged such as to receive the liquid to be filtered; the filter cartridge (3) is internally connected to the liquid outlet (7) such that the liquid to be filtered contained in the chamber (2) is filtered across the wall (4) of the filter cartridge (3) and reaches the liquid outlet (7); the scraping means (6) are arranged externally of the filter cartridge (3) and internally of the chamber (2).
Abstract:
A machine for driving inserts into pieces of sheet metal includes an automatic loading device (60) having a plurality of cartridges (62) containing inserts (70) of different types. Each cartridge (62) can be connected selectively to an insert-supply duct integral with the punch (46).
Abstract:
A device for driving inserts into pieces of sheet metal includes a punch (1, 100) having a longitudinal axis of symmetry (5, 105), a thrust surface (9, 109) and a through hole extending along its longitudinal axis (5, 105) which constitutes a supply duct (6, 106) for the inserts. The through hole (6, 106), extends through the thrust surface (9, 109). A thrust rod (50, 150) applies a driving force to the inserts to move them into position in front of the thrust surface (9, 109) of the punch (1, 100). The thrust surface (9, 109) drives the head (42, 142) of the insert (40, 140) into a piece of sheet metal (30, 130) through a hole (31, 131) while plastically deforming the periphery of the hole (31, 131) which interfaces with the head (42, 142).
Abstract:
A panel bending machine comprising: - a fixed lower table (3), - a movable upper table (4), - a plurality of blank holder tools (1,2) borne by the lower table (3) and by the upper table (4) and able to hold a piece of sheet metal (12) in a fixed position, and - a bending device (5) comprising a support structure (8) bearing two mutually opposite bending tools (6, 7) in fixed position with respect to each other. The upper table (4) is movable relative to the lower table (3) in a vertical plane, and a plurality of bending punches and dies (19, 20) are provided, susceptible to be mounted on the upper table and on the lower table (3, 4) to replace the blank holder tools (1, 2).
Abstract:
A method and apparatus for the production of bent sheet metal pieces (12) is disclosed. In the method or apparatus, a cut (14) is made in a sheet of sheet metal (10) that defines the perimeter of piece (12) to be obtained. The cut (14) is interrupted at preselected points to form a series of microjoints (16) that keep the plan development of the piece (12) united with the stiffening frame (18) constituted by the remaining part of the metal sheet (10). At least one window (36, 38) is formed in the stiffening frame (18) in order to allow a pair of bending tools having a length greater than the length of the bend to form a bend (20, 22) on the piece (12) without interfering the stiffening frame (18) while the bend is being formed.
Abstract:
A magnetic separation device (1) for separating ferrous material contained in a liquid circulating in a heating circuit, comprising: a first container (2) comprising an inlet (20), an outlet (21), a discharge (22); a magnet (4); a second container (3) arranged internally of the first container (2) and comprising a plurality of openings (30); a casing (5) for containing the magnet (4) arranged at least partially internally of the second container (3), so as to be accessible from outside the magnetic separation device (1). The magnetic separation device (1) is designed so that it can assume a use configuration (A), in which the inlet (20) is in fluid communication with the outlet (21) and the magnet (4) is inserted in the casing (5), and a washing configuration (B), in which the inlet (20) is in fluid communication with the discharge (22) and the magnet (4) is extracted from the casing (5). The openings of the plurality of openings (30) of the second container (3) are reciprocally arranged so that when the device is in the use configuration (A), the liquid crosses the second container (3) and strikes the casing (5) so that the magnet (4) attracts the ferrous material contained in the liquid, and so that when the device is in the washing configuration (B), the liquid crosses the second container (3) drawing the ferrous material towards the discharge (22).
