摘要： In the width-direction bending step for the blade member, the blade member is clamped by a pair of rotary press claws 13, 14 from both sides in the thickness direction to be compressed in the thickness direction, whereby the compressed portion is extended in the longitudinal direction of the blade member and the blade member is bent in the width direction. In the thickness-direction bending step for the blade member, a working die portion comprises: a thickness-direction bending shaft 31; and a thickness-direction bending cylinder 32 which is fitted in a turning paired state onto the thickness-direction bending shaft. The thickness-direction bending shaft 31 and the thickness-direction bending cylinder 32 are relatively rotated, whereby the blade member is bent in the thickness direction.

摘要： A composite utility knife blade and method of making such a blade involves butt joining a tool steel wire to a front edge of an alloy steel backing strip. The wire is electron beam welded to the backing strip to form a composite strip defining a first metal portion formed by the alloy steel backing strip, a second metal portion formed by the tool steel wire, and a weld region joining the first and second metal portions. The composite strip is then annealed, and the annealed strip is straightened to eliminate any camber therein. The annealed composite strip is then hardened such that the first metal portion defines a surface hardness within the range of approximately 38 Rc to approximately 52 Rc, and the second metal portion defines a surface hardness within the range of approximately 60 Rc to approximately 57 Rc.

The hardened strip is then subjected to at least two tempering and quenching cycles. Then, facets are formed on the edge of the second metal portion to form a straight, tool steel cutting edge along at least one side of the composite strip. The composite strip is then scored at axially spaced locations to form a plurality of score lines, wherein each score line is oriented at an acute angle relative to the axis of the strip, and the plurality of score lines define a plurality of blade sections and scrap sections located between the blade sections. Each scrap section is bent outwardly relative to a plane of the composite strip on one side of a respective score line, the composite strip is then pressed on an opposite side of the respective score line, and the respective blade section is then snapped away from the bent scrap section along the respective score line.

摘要： A composite utility knife blade and method of making such a blade involves butt joining a high speed steel wire to a front edge of a carbon steel backing strip. Electron beam welding the wire to the backing strip and, in turn, forming a composite strip defining a first metal portion formed by the steel backing strip, a second metal portion formed by the high speed steel wire, and a weld region joining the first and second metal portions. The composite strip is then annealed, and the annealed strip is straightened to eliminate any camber therein. Then, a plurality of notches are formed, such as by punching, in axially spaced locations relative to each other along the back edge of the first metal portion of the annealed composite strip. The annealed and punched composite strip is then hardened such that the first metal portion defines a surface hardness within the range of approximately 38 Rc to approximately 52 Rc, and the second metal portion defines a surface hardness within the range of approximately 60 Rc to approximately 75 Rc. The hardened strip is then subjected to at least two tempering and quenching cycles. Then, facets are formed on the edge of the second metal portion by grinding, honing and stropping to, in turn, form an approximately straight, high speed steel cutting edge along the side of the composite strip opposite the back edge of the first metal portion. The composite strip is then die cut along shear lines axially spaced relative to each other. Each shear line is oriented at an acute angle relative to the back edge of the first metal portion, and two notches are located between adjacent shear lines. The die cutting of the composite strip forms a plurality of utility knife blades, wherein each utility knife blade defines an approximately trapezoidal peripheral configuration.

摘要： The present invention relates to an apparatus for bending a strip material such as a band blade. A stationary die having a slit through which the strip material is passed is integrated with a shaft body. A movable die which cooperates with the stationary die to bend the strip material is formed into a cylindrical shape. The rotation is transmitted from an electric motor, only to one end of the movable die. The replacement of the stationary die is facilitated by attaching the lower end of the shaft body by mounting bolts to a machine base through a mounting member. When the stationary die is to be replaced, the mounting bolts are removed, the shaft body and the mounting member are pulled out to the lower side of the machine base, and another shaft body is inserted from the lower side of the machine base, and the mounting member is fixed to the machine base by using the mounting bolts.

摘要： The present invention relates to an apparatus for bending a sheet die cutting knife to a specified shape, in which a knife is supported by a supporting mechanism and a clamping mechanism in connection with the upper face of the surface plate and bent by a bending mechanism in which the edge portion of the bending die which constitutes the bending mechanism is brought into contact, through vibrations and drive, with the knife side opposite to the direction along which the knife is about to be bent, by alternatively repeating a specified staying time and knife feeding time by the knife feeding mechanism every time such a bending process is carried out. This makes it possible to bend the knife to various shapes by properly changing the operating time of the bending mechanism and the feeding mechanism with a control device.

摘要： A hedge cutting bar is shown and described as having rivets for securing a cutting blade between a retaining blade and a stationary blade. The rivet structure includes a central flange and distal hubs whereby the central flange may occupy slots in the cutting blade while the hubs attach within respective mounting apertures of the stationary blade and the retaining blade. The thickness of the flange is greater than the thickness of the cutting blade whereby a gripping force provided by the rivet is taken up at the flange to avoid pinching of the cutting blade between the stationary blade and the retaining blade. The described fastening arrangement is less suspectable to loosening under the vibrational forces imposed during use of the hedge cutting bar than that of prior fastening arrangements.
摘要翻译：树篱切割杆被示出并描述为具有用于将切割刀片固定在保持刀片和固定刀片之间的铆钉。铆钉结构包括中心凸缘和远端毂，由此中心凸缘可以占据切割刀片中的狭槽，同时轮毂附接在固定刀片和保持刀片的相应安装孔内。凸缘的厚度大于切割刀片的厚度，由此由凸缘提供的夹持力被吸收在凸缘上，以避免刀片在固定刀片和保持刀片之间的夹紧。所描述的紧固装置在使用树篱切割杆时施加的振动力比先前的紧固装置的松动更不容易松动。

摘要： A method of making knives in which a separate blade and handle are bonded together by electron-beam welding which reduces the susceptibility to corrosion at the weld area and thereby increases the knife life. In addition, the blade can be unhardened when welded, and hardened after welding to reverse any structural changes occurring in the metal adjacent the weld and thereby more reliably reduce the susceptibility to corrosion at the weld area. The step of hardening the blade after welding can be used to provide satisfactory corrosion resistance in knives where separate blades and handles are joined by other welding techniques such as electrical seam and oxyacetylene welding.
