Abstract: A process for manufacturing a surgical needle incorporates at least one pressing operation which, preferably, in conjunction with a trimming and/or etching process, ultimately forms the sharpened needle end. The grinding operation in the preferred process does not produce the primary sharpened edges of the needle, but, rather is incorporated, in one instance, to reduce excess needle material prior to the pressing operation. Consequently, the amount of flash material generated during pressing is substantially reduced. This feature desirably enhances the subsequent trimming and etching operations, and produces a needle which is extremely sharp, durable and exhibits an improved retention of sharpness over periods of prolonged use.

Abstract: A method of using a tool for punching orifice that has wall surfaces extending at an angle relative to a generally planar surface of a workpiece. The method includes sequentially forming two spaced apart impressions formed in the workpiece between first and second generally planar surfaces spaced apart along a longitudinal axis of the workpiece. The two spaced apart impressions form a first orifice wall surface disposed at an obtuse angle with respect to the generally planar surface facing the tool and a second orifice wall surface disposed at an acute angle with respect to the generally planar surface, and coincidental with the punching process, a retention arrangement that secures the workpiece during the forming of the orifice.

Abstract: There is provided a first die in which a plurality of projections are arrayed in a first direction with a fixed pitch. Each projection is elongated in a second direction perpendicular to the first direction. The first die faces a first face of a plate member.

Abstract: The present invention is a bending machine for bending material such as steel to form cutting dies for products such as cloth, leather or the like. Coiled material is fed through a material washer, straightener and printer by a material feeder to a bending head. If required the material is forwarded through the bending head to a heating unit and retracted to the bending unit to aid in bending. A nicking tool is also provided ahead of the bending tool to nick the material. The nicks enable the cutting die to cut notches in the product being cut. A support surface at the output end of the machine supports the material as it is bent into the required form.

Abstract: A method of producing a forged part includes holding a material by a jig, upsetting the material, held by the jig, to a predetermined length by a pair of upsetting dies disposed on both ends of the material, while pressing the upsetting dies on the material, so as to produce large-diameter portions at the respective axial ends of the material. Next, a bending operation and a forging operation are made to the upset material, in that order. When forging, a direction, in which the material is forged, is set, so that a burr generated on the material by upsetting is included in a burr generated on the material by forging. Next, a finish-machining operation is made to the forged material to remove the burr left on the outer periphery of the material after forging. Thereafter, the finish-machined material is drilled to form bush-mounting holes in the large-diameter portions.

Abstract: There is provided a first die, in which a plurality of projections are arrayed in a first direction with a fixed pitch to form at least one array of the projections. Each of the projections is elongated in a second direction perpendicular to the first direction. The first die faces a first face of the plate member. A second die is opposed to the first die while supporting a second face of the plate member. At least one first region is formed on the plate member so as to have a less rigidity than another region of the plate member. The first die and the second die are approached so that the projections are dug into a second region in the first face of the plate member, thereby forming partitioned recesses to be pressure generating chambers of a liquid ejection head. The at least one first region is adjacent to at least one of ends in the first direction of the second region, such that the first region and the second region are arranged in the second direction.

Abstract: A hand rivet squeezer with adjustable handles includes a riveting head body, and C-shaped anvil yoke and stationary and lever swing-arm handles attached to the body. A mechanical linkage inside the body converts pivoting forces applied to the lever swing-arm into axial forces applied to a plunger pushing it from inside the body into the C-shaped yoke. The preferred mechanical linkage is a rack-and-pinion type design or alternatively a cam between the lever swing arm and the plunger. The handles are adjustable such that their angle relative the rivet head body can be varied depending on the access available around a solid rivet to be installed. The handles are engaged or locked to the body but may be unlocked or slidably disengaged and pivoted up to 90 degrees relative the body.

In order to prevent forces resulting from compressive or stretching strain during the bending process, one of these means does not apply any longitudinal forces onto the wire by design. In another implementation, the apparatus for bending orthodontic wires has a gimbal-mounted gripper for bending the wire. Furthermore, a method is disclosed for applying two bends at the same longitudinal wire location in two different directions.
