At least one of the passages (33, 34) can be closed means of a pivoting module (6), whereby the first plunger unit (21) and/or the second plunger unit (22) can be activated.
METHOD FOR MANUFACTURING A HIGH STRENGTH STEEL SHEET AND SHEET OBTAINED
A method for manufacturing a steel sheet having a yield strength YS of more than 1000 MPa, a tensile strength TS of more than 1150 MPa and a total elongation E of more than 8%, includes the steps ofpreparing a steel sheet through rolling from a steel containing in percent by weight 0.19% to 0.22% C, 2% to 2.6% Mn, 1.45% to 1.55% Si, 0.15% to 0.4% Cr, less than 0.020% P, less than 0.05% S, less than 0.08% N, 0.015% to 0.070% Al, the reminder being Fe and unavoidable impurities; and soaking the sheet at an annealing temperature TA between 860 C. and 890 C. for a time between 100 s and 210 s, cooling the sheet to a quenching temperature QT between 220 C. and 330 C., from a temperature TC not less than 500 C. at a cooling speed not less than 15 C./s, heating the steel sheet during a time between 115 s and 240 s up to a first overaging temperature TOA1 higher than 380 C., then heating the sheet during a time between 300 s and 610 s up to a second overaging temperature TOA2 between 420 and 450 C., cooling the steel sheet to a temperature less than 100 C. at a cooling speed less than 5 C./s. The structure of the steel contains more than 80% of tempered martensite, more than 5% of retained austenite, less than 5% of ferrite, less than 5% of bainite and less than 6% of fresh martensite.
Device for the manufacture of pharmaceutical patches
The present invention relates to a device for the manufacture of pharmaceutical patches, a method for the manufacture of pharmaceutical patches, and a package comprising a pharmaceutical patch obtainable by said method.
Rotary cutting die apparatus for cutting corrugated board including retainers for maintaining trim strippers closely adjacent trim cutting blades
A rotary cutting die assembly is provided that includes a die cylinder, an anvil, and a die board mounted to the die cylinder. The die board includes a series of trim cutting blades. Disposed on the outside of each trim cutting blade is a trim stripper. Secured to the die board adjacent the outside of the trim strippers is a series of retainers that generally retain the trim strippers between trip cutting blades and the retainers. This generally prevents cut pieces of trim from being packed and wedged into a gap between the trim cutting blades and the trim strippers.
Nick breaking device
A nick breaking device includes: a conveyor forming a transfer path on which a plate-shaped element having nicks formed thereon is transferred; and one or more pressing rollers provided on the transfer path of the nicks of the plate-shaped element so as to press the plate-shaped element such that the plate-shaped element is transferred while having a continuous wave shape and to break the nicks formed on the plate-shaped element.
Method for modifying the cutting trajectory for parts intended to be cut from a flexible material
A method is provided for automatically modifying the cutting paths for parts to be cut out from a flexible material by automatically moving a cutter tool along predetermined cutting paths. The cutting paths are associated with each part being defined by a succession of cutting segments forming a polygon. Two cutting segments are identified and belonging to two different parts for cutting out in the material and for which a maximum distance condition between these cutting segments is satisfied. Two cutting segments are verified for being situated facing each other, and that no other cutting segments lie between the two cutting segments. A common cutting path for the two cutting segments is computed, and a common cutting path is connected to the cutting paths of the two parts for cutting out to obtain modified cutting paths for the two parts for cutting out.
Apparatus and method for stripping away/pushing out a punched grid/internally formed part and ejecting a blanked part in a precision blanking press
In an apparatus and a method for stripping/pushing out a punched grid and for ejecting a blanked part from a die in a precision blanking press, the force of stripping/pushing out and ejection can be adjusted independent of the knife-edged ring force and the counterstay counteracting force while reducing the mass of the knife-edged ring and counterstay pistons, increasing the stripping/pushing and ejection speeds, and at the same time simplifying the hydraulic circuit.
SYSTEM FOR EXTRACTING CUT LAMINAR MATERIALS FOR CUTTING MACHINES OF FLEXIBLE LAMINAR MATERIALS
The system comprises a cutting table (1), said cutting table (1) being formed by a cutting surface (1A), which is formed by brush blocks (3), the brush blocks (3) comprising bristles, and combs (4) equipped with protrusions (5, 6) and installed on one edge of said cutting table (1), defining a proximal end that is closer to the edge of the cutting table (1) and a distal end further from the edge of the cutting table (1), the distal end of the protrusions (5, 6) of each comb (4) being inserted between the bristles of the brush blocks (3), in which the comb (4) comprises first protrusions (5) and second protrusions (6), the distal end of the first protrusions (5) being further from the edge of the table (1) than the distal end of the second protrusions (6).
Method and device for placing an insert in a cavity formed in a foil
To place an insert cut out of film with no gaps in a cavity formed in a foil, after placing the foil on a supporting substrate, the cavity is punched into the foil by means of a tubular cutting punch comprising an inner pusher with a cutting edge in the required shaped of the cavity and the insert, so that the edge goes through the thickness of the foil and cuts a slug out of it; the punch is lifted with the slug held inside the punch, without moving the foil, the film is brought between the foil and the edge of the punch, the punch is lowered once again so as to cut the insert out of the film and then push the insert cut in that way in the cavity with a pusher, and the punch and the pusher are removed, with the insert held in place in the cavity.
Clearing device, operating method thereof, and cutting device
A clearing device, an operating method thereof, and a cutting device are provided. The clearing device includes: an operating platform, including an operating surface; a first clearing unit, provided on a side of the operating platform close to the operating surface; a control unit, configured to communicate with the first clearing unit and control a clearing operation and a count of the operation of the first clearing unit; at least one detecting unit, provided on the operating platform and communicatively connected to the control unit, wherein the first clearing unit is configured to clear a foreign matter on the operating surface, the detecting unit is configured to detect a degree of cleanliness of the operating surface and send to the control unit a data signal which reflects the degree of cleanliness of the operating surface.
