摘要： A pair of rotary die cylinders having co-acting cutting blades formed by integral lands projecting generally radially outwardly from the main body of each cylinder and a method of making them by rough machining a tool steel workpiece with conventional cutting tools to form the general contour and path of the cutting blades and thereafter final machining and simultaneously heat treating the cutting blades with a laser to provide an accurately formed and hardened cutting blade. Preferably, the rough machining with conventional cutting tools and the final machining and heat treating by a laser are performed with the same machine tool, such as a computerized numerical control (CNC) machining center. Such a machining center permits rapid and accurate rough machining as well as accurate final laser machining of the cutting blades. The more accurate final machining accomplished by a laser produces a more accurately formed cutting blade and also simultaneously heat treats the blade with minimal distortion of the blade and without any significant distortion of the core or body of the cylinder.

摘要： A method of making a rotary cutting tool for cutting a web of material comprises the steps of roll forming a first flexible die plate into a cylindrical shape, mounting the cylindrically shaped die plate onto a cylindrically shaped fixture, and machining cutting elements onto the roll formed die plate. The roll formed die plate may then be removed from the fixture and attached to a cylinder. The first die plate can cooperate with a second die plate attached to a second cylinder to cut the thin web of material.

摘要： A system to accurately align relative to each other a pair of rotary die cylinders having co-acting cutting blades formed by integral lands projecting generally radially outwardly from each cylinder. Each cylinder has an alignment groove formed therein such that when the cutting blades of the die cylinders are in alignment, the alignment grooves of each cylinder are aligned and define a slot between the cylinders which is constructed to receive an alignment pin. To initially align the die cylinders relative to each other, they are free to move both axially and rotatably relative to each other to permit the die cylinders to fully engage an alignment pin or pins inserted between the cylinders. Preferably, an alignment slot is provided adjacent each end of each cylinder with each slot constructed to receive a separate alignment pin to more accurately register or align the die cylinders relative to each other. With the cylinders fully engaging the alignment pins ensuring accurate alignment of the die cylinders, the bearings and other adjustment and cylinder mounting mechanisms may be locked in position to secure the cylinders in position and the alignment pins subsequently removed prior to operation of the rotary die cylinder machine.

摘要： A pair of rotary die cylinders with lands having coacting cutting edges which cut blanks from a web of material passing through the nip of the rotating dies. In cross section each land has an outer face and a pair of spaced apart side faces which are parallel to each other and perpendicular to the chord of the outer face to provide a clean cut and facilitate release of the cut blank from the cutting blades as it emerges from the nip of the dies. The die cylinders are journalled for rotation by recesses with frusto conical locating surfaces in their opposed ends. Each die cylinder is made by machining the recesses in the opposed ends of a generally cylindrical workpiece of tool steel and then utilizing the recesses to locate and orient the workpiece relative to a cutting tool to produce a cylindrical surface on the workpiece concentric with the axis of the recesses and then to machine away portions of the periphery of the cylindrical surface to form the cutting blade lands thereon. After machining is completed the cutting blade lands may be hardened by heat treating utilizing a laser beam directed onto the lands to heat them at an elevated temperature so that upon quenching they are hardened without any substantial hardening and resulting distortion of the core or body of the workpiece.
摘要翻译：一对旋转模具缸，其具有具有共同切割边缘的平台，其从穿过旋转模具的辊隙的材料卷材切割坯料。在横截面中，每个平台具有外表面和一对间隔开的侧面，它们彼此平行并且垂直于外表面的弦线，以提供干净的切口并便于将切割的坯料从切割刀片上释放从模具的咬合处出现。模具缸被支承在其相对端部的具有截头圆锥形定位表面的凹部旋转。每个模具缸通过在工具钢的大致圆柱形工件的相对端中加工凹槽来制造，然后利用凹槽来定位和定向工件相对于切削工具，以在工件上同轴的圆柱形表面凹部，然后将圆柱形表面的周边的部分加工，以在其上形成切割刀片台面。在加工完成之后，可以通过利用被引导到焊盘上的激光束进行热处理来切割刀片焊盘，以便在升高的温度下加热它们，使得在淬火时它们被硬化而没有任何实质的硬化，并导致芯体或主体的变形工件。

摘要： A rotary cutting tool comprises a rotary die cylinder having an axis of rotation, a pair of sides and a cylindrical surface, a die plate positioned around the cylindrical surface of the die cylinder and rigidly attached to the die cylinder at a first location, and an adjustable slide assembly operatively connecting the die plate to the die cylinder at a second location, and slidable with respect to the die cylinder between a retracted position and an extended position. The adjustable slide assembly is slidable along either a first direction around the axis of rotation of the die cylinder or a second direction parallel to the axis of rotation of the die cylinder. Adjustment of the adjustable slide assembly adjusts the position of the die plate with respect to the cylinder. The cylinder may be formed as a single piece assembly or as a first piece and a bar attached to the first piece. The bar can be machined to define in combination with the first piece the cylindrical surface.

摘要： An improved rotary die cutting apparatus and method for removing scrap material from work pieces such as paperboard blanks. One of the dies of a pair of rotary cutting dies is provided with gripper elements that extend over at least a portion of the area of the die corresponding to the areas over which the scrap portions are generated. The gripper elements grip, without piercing completely through, the scrap portions generated by the cutting operation of the dies. A stripping knife extends across the die carrying the scrap portions at a height above the gripper elements that provides clearance between the gripper elements and the stripping knife but contacts the scrap portions retained on the gripper elements.
