Abstract: The metal bending apparatus is an easily portable apparatus with substantial frame integrity. The vertical plate of the apparatus removably receives any of a plurality of different diameter nodes. Each node enables a different radius to be bent into existing sheet metal. While the ideal embodiment features node diameters of ¾ inch, 1 inch, 1 1/16 inch, and 1¾ inch, the nodes are not limited to these diameters only. To bend sheet metal, an edge of the metal is removably secured to the back side of the vertical plate via the metal retainer. The pivoting assembly is then pivoted over the metal and downwardly toward the front of the frame. The metal is thereby bent to the desired radius.

Abstract: In a reel furnace having a strip reeling device, the strip reeling device comprising a reel shaft, a reel drum supported on the reel shaft and at least one stirrup clamp, the reel shaft passing through a furnace wall delimiting the inner space of the reel furnace and being supported rotatably in supporting bearings outside the reel furnace, the reel drum and the at least one stirrup clamp being positioned with respect to one another by means of a connection element, and a gap for receiving a strip head being set between the reel drum and the at least one stirrup clamp. The useful life of the reel drum is appreciably increased and a strip thickness-dependent setting of the entry gap for the hot-rolled strip is ensured when the reel drum is designed as a closed body and the connection element is designed as an actuating device for fixing a specific gap width between the reel drum and the stirrup clamp and for clamping a strip head which has entered the gap.

Abstract: The present invention relates to a method and tooling suitable for handling closure blanks (5) having an external radius (6) at their cut edge at production speeds of about (1200) closures per minute. The external radius (6) limits formation of “angel hair” (a common problem in metal closure production). However, reversing the external radius causes a problem, when producing metal closures having a conventional inward curl at their peripheral edge. Accordingly, the invention proposes a modified curling rail (40) having a first portion (41) to uncurl the external curl (6) on the closure blank (5) and a second portion (45) to urge the straightened side wall of the closure blank (5) towards an inward curl.

As the first and second sets of cam followers follow the first and second cam surfaces, the inner knockout tooling and the outer die tooling move toward or away from an article to be worked on.

Abstract: Disclosed is a rolling mill comprising a roll stand with working rolls, a roll train located at the feeding end of the roll stand, and a control device. The working rolls form a roll gap. The control device triggers the roll stand such that the working rolls rotate at a certain peripheral speed while triggering the roll train located at the feeding end of the roll stand in such a way that the leading edge of the strip-shaped rolling stock reaches the roll gap at a feeding speed that is greater than the peripheral speed. The control device adjusts the peripheral speed and the feeding speed to each other in such a way that a potential angled position of the leading edge relative to the roll gap is at least reduced as a result of said adjustment.

Abstract: In a reinforcing bar binder in which a wire reel around which a reinforcing bar binding wire is wound is rotatably housed in a housing chamber in a binder main body, the wire is pulled out from the wire reel and wound around reinforcing bars, and the reinforcing bars are bound by twisting the wound portion, an opening is formed through one of both side walls of the housing chamber at a position corresponding to a shaft receiving portion formed on the wire reel. On the one side wall, a reel receiver which is supported so as to come into and come out from the opening is fitted to the shaft receiving portion of the wire reel when it is pushed into the inside of the side wall. A reel stopper moves along the wall surface of the one side wall and can engage with the reel receiver fitted to the shaft receiving portion. A leaf spring urges the reel stopper engaged with the reel receiver to the pushing-in side.

Abstract: A release mechanism for use in a leveling apparatus that performs a leveling process on a work object that has been wound in a coil configuration as a result of the work object being passed between a front side work roll in contact with the front side surface of the work object and a back side work roll that is in contact with the back side surface of the work, wherein the releasing mechanism switches between a work clamp state that allows performance of the leveling process and a release state that releases the work object from the clamp state by displacing a work roll support member that supports one of the work rolls relative to the another support member to change a distance between the work rolls by utilizing rotational movement of an electric motor.

Abstract: A primary intermediate formed article is formed into a substantially columnar shape. A secondary intermediate formed article is obtained by piercing a preliminary hole in the primary intermediate formed article such that a radial thickness of a prospective cam top part is larger than a radial thickness of a prospective cam base part, and by forming a positioning part. The positioning part is brought into contact with a tertiary intermediate forged article forging die so as to be positioned, and the secondary intermediate formed article is pressed and forged to form a tertiary intermediate forged article including a cam top, a cam base, and a deformed hole formed by deforming the preliminary hole. A finished cam lobe is obtained by piercing, in an area including the deformed hole.

Abstract: The invention relates to a roll bending device for the control of profile and flatness in the rolling of metal plates or strips. In particular the invention relates to the well known principle of roll bending by using hydraulic cylinders to modify the load distribution between rolls of a rolling mill stand and a rolled stock e.g. a metal plate or a strip in order to control the profile and flatness of the metal plate or strip. A special design to allow safe roll bending even at large roll gauges is presented. The new design allows safe operation even at large roll gauges and high side loads.
