A precision positioning device of a unit-type die cutting & hot stamping machine includes a positioning element on an input end of a first imprinting element and a positioning element on an output end of each imprinting element. Two neighboring positioning elements accomplish the positioning between the two positioning elements together. Each positioning element is constituted by a positioning assembly installed symmetrically on each end of the imprinting element. The positioning assembly includes a positioning rod which can rotate against an installation shaft. Each positioning rod includes a positioning block which is provided with a reference surface. A rear side of the gripper is provided with a reference matching surface. By the positioning elements, the accuracy in the art of die cutting & hot stamping can be assured when the machine is performing a multiple-working-position procedure.

The invention relates to a method for producing a stamped metal sheet which has at least one interrupted cutting line in (17) for producing perforations or holding points, which is arranged on a base sheet (15), characterized in that a laser beam is used for producing at least one interruption (14). The invention also relates to a stamped metal sheet.

A die press system includes a die press device including a fixed platen and a moving platen, and accessory parts to be installed on the die press device. The accessory parts include a cutting blade set comprising a first cutting blade having a first tooth profile, and a second cutting blade having a second tooth profile, wherein one of the first cutting blade or the second cutting blade is to be installed on the fixed platen, and a pad set comprising a first padding block comprising a first padding layer composed of a first padding material having a first Shore value, and a second padding block comprising a second padding layer composed of a second padding material having a second Shore value, where the first Shore value is different from the second Shore value.

A manufacturing method of a three-dimensional object includes: a positioning step, an adhering step, a placing step, an additive manufacturing step, and a detaching step. In the positioning step, a fixing plate in which adhesive injection holes are formed is placed on a thin plate, and the thin plate is positioned on the fixing plate. In the adhering step, an adhesive is dripped to the adhesive injection holes, and the fixing plate is adhered to the thin plate. In the additive manufacturing step, a three-dimensional object in which the thin plate and a solidified layer are integrated is formed. In the detaching step, adhesion between the thin plate and the fixing plate is removed by a removing agent corresponding to the adhesive.

A die cutter includes an anvil cylinder, a die cylinder, and a sleeve that is mounted on the die cylinder for generating a pressing force on an anvil cover to force a locking component of the anvil cover into a locking component receptor of the anvil cylinder.

A system and a method for compensating misalignments of a die for cutting cardboard of a die cutter. The system comprises a processor configured to detect height-correcting elements in an image of a correction template for the die, and further configured to produce a digital file comprising a digital representation of detected height-correcting elements; and an optical device for projecting images configured to project the digital representation of the digital file on a pressure compensation plate of the die cutter. The method comprises digitally detecting height-correcting elements in an image of a correction template for the die; producing a digital representation of detected height-correcting elements; and projecting the digital representation on a pressure compensation plate of the die cutter.

Systems and methods of generating an image of a modified desired cutting die are described herein. One image of a desired cutting die is received; an entire cutting edge of the desired cutting die in the image is identified, an image of a modified desired cutting die based on the offset distance and desired tolerance is generated. By using the systems and methods, The amount of material used to create a plurality of pieces of the material with a cutting machine is reduced.

The invention is directed to a cutting post for mounting on a cutting apparatus and to the cutting apparatus. The cutting apparatus has at least one cutting blade and at least one cutting post. The cutting post includes at least one receptacle for the cutting blade and at least one cutting element having a cutting edge arranged at the head end of the cutting post. The cutting blade has a cutting blade edge and is held in the receptacle of the cutting post. The cutting blade edge of the cutting blade and the cutting edge of the cutting element of the cutting post conjointly form a continuous cutting contour.

A method of making a counter-die cutter for a die cutting machine having a die cutter and respective counter-die cutter includes: acquiring a digital drawing of a die cutter to be made, which is provided with comparing means; acquiring a digital drawing of a respective counter-die cutter to be made; providing a wooden support of the die cutter; making a plurality of comparing means on the support of the die cutter; making the die cutter; detecting the position and/or orientation of the comparing means of the finished die cutter; comparing the detected position and/or orientation with corresponding position and/or orientation of the comparing means being in the digital drawing of the die cutter; modifying the digital drawing of the counter-die cutter based on the detected differences to adapt the digital drawing to the finished die cutter; and making the counter-die cutter based on the modified digital drawing.

A knife cylinder is provided with a restraint parts disposed within a fixation hole; a compression coil spring for pressing the restraint parts inwardly of the fixation hole; an operating parts entering the inside of the restraint parts through a mounting hole; a protrusion provided to the restraint parts; a helical groove provided in the operating parts, the helical groove engaging with the protrusion and being configured so that, when the operating parts rotates, the helical groove can move the restraint parts from a first position to a second position; and a blocking groove provided in the outer surface of the operating parts and blocking the rotation of the operating parts in the reverse direction when the restraint parts is located at the second position.
