Abstract: A process for producing a hollow monoblock shaft from a pipe, the pipe initially having a constant diameter and a constant wall thickness, and the monoblock component including at least one area of its length being of a smaller outside diameter and a greater wall thickness than the constant diameter and constant wall thickness of the pipe. The process can be carried out simply and economically by the following process steps: selecting a pipe with a wall thickness which corresponds to the smallest wall thickness of the finished component, partial heating of at least one area of the pipe, axial upsetting the heated area of the pipe and radial forging the heated area of the pipe.

Abstract: An entry guide for a roll forming machine having fixed stop members for the different widths of sheet metal material which can be accommodated by the roll forming machine. The fixed stop members are offset in the vertical direction. Accordingly, when the roll forming machine is adapted to accommodate a different width of sheet metal material, there is no need to adjust the entry guide.

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.

The method uses an elongate preform member, and comprises forcing the preform member in the axial direction of its core through a helical deformation arrangement (22) in order to deform the preform member helically.

Abstract: A method of processing metal parts and the like by blanking includes the steps of performing a first blanking step on a semi-finished product in order to produce a blanked semi-finished product, and performing a subsequent processing of the blanked semi-finished product to produce a finished product. The first blanking step is performed leaving an allowance on the blanked semi-finished product, and wherein the subsequent processing includes at least one second blanking step by which the allowance is removed from the blanked semifinished product.

Abstract: A sheet of material (21, 61, 81) formed for control bending along a bend line (23, 63) while maintaining a continuous web of material (26) across the bend line (23, 63). The sheet has at least one groove (22, 62, 82) formed therein with a central groove portion (24, 64, 84) extending in the direction of and positioned proximate to a desired bend line (23, 63).

Abstract: The golf club hosel bending fixture immovably secures a golf club head therein in order to adjustably bend the hosel angle of the club head to “fine tune” the characteristics of the club. The fixture includes an angularly articulating crown jaw assembly, a relatively fixed lower jaw assembly generally opposite the crown jaw assembly, a longitudinally disposed back jaw assembly, and a club head face jaw disposed at the base of the crown jaw track in order to remain aligned with the crown jaw. The jaw clamp and base mechanisms are laterally symmetrical, in order to provide for both left- and right-hand club heads. Two orthogonal gauges are provided to check both loft and lie angles of the hosel relative to the club head and face. The gauges may be adjustably positioned to either side of the fixture, to check either left- or right-hand club heads.

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.

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.
