A tight space pilot, tight space pilot assembly, and related method includes a tight space pilot that can be installed into a die without fasteners, fastener apertures, or added blocks for mounting. The tight space pilot assembly includes ejectors that are retained by the pilot and a retaining ring that holds the tight space pilot in place in a die member.

A fin manufacturing apparatus includes: a first inter-row slit device that forms, by forming in a thin metal plate having a plurality of openings a plurality of slits extending in a longitudinal direction of the thin metal plate while leaving an uncut portion between the plurality of slits, metal strips partially coupled to each other in a transverse direction; a feed roller and a feeding device that convey, in the longitudinal direction, the metal strips in which the plurality of slits is formed by the first inter-row slit device; and a stacking device that (i) forms fins by cutting the uncut portion via which the metal strips are coupled to each other, to separate the metal strips and by cutting the metal strips at regular length intervals and (ii) stacks the formed fins.

A device and a method for manufacturing a laminated iron core are provided for including: a first supply unit of supplying a first adhesive to a first part of a predetermined region, the predetermined region corresponding to a punched member of a strip-shaped metal sheet intermittently fed in one predetermined direction; a second supply unit arranged at a downstream side in a conveyance direction of the metal sheet with respect to the first supply unit, and of supplying a second adhesive to a second part different from the first part of the predetermined region; and a punching unit of punching the predetermined region of the metal sheet to which the first supply unit and the second supply unit supply the first adhesive and the second adhesive, so as to form the punched member having the first adhesive and the second adhesive applied on the first part and the second part.

A device for manufacturing a laminated iron core includes: a punch unit configured to form protrusions, and including N number of punches as a set, the N being a natural number larger than M; and N number of auxiliary punches. The N number of auxiliary punches are configured such that L number of auxiliary punches selected from the N number of auxiliary punches performs a nullification processing on a metal sheet, the nullification processing being configured to nullify a processing with the L number of punches among the N number of punches, the L being the natural number that is obtained by subtracting the M from the N. According to the above configurations, for example, since a processing position with the plurality of punches is limited in one position, a positional accuracy of protrusions formed in punched members with the plurality of punches is improved.

A stamped steel detectable warning tile and method of forming such includes preforming structures in the tile and subsequently coining the structures to form tactile portions to provide satisfactory end results. Further, the tactile portions can be formed in a staggered fashion along a press to distribute tonnage and extend the lifespan of the press, as well as control a curvature of the tile due to the press operations.

A forming tool includes at least one first die half where the first die half has an insert part which is designed to move a finished component out of the first die half along a direction of motion where a displacement direction of the insert part is inclined relative to the direction of motion.

The invention relates to an apparatus for working, in particular for working without machining, for example for separating and/or forming, a web of material, having a plurality of individual tools for different manners of working the web of material with designated workpieces temporarily held therein, and having a machine direction along which the web of material with the designated workpieces and the plurality of individual tools can be moved incrementally relative to one another in such a way that the web of material can be worked multiple times within one work cycle by means of the plurality of individual tools, wherein the individual tools are designed as individual modules which can be fixed to one another to form an individual module cluster, but can be detached as well.

A shell including a central panel with an expandable bubble disposed thereon is provided. The use of an expandable bubble allows for an expandable rivet button and thereafter an expandable rivet that has an enhanced overlap of a tab body. Such an expandable rivet allows for the use of a metal sheet with a thinner base thickness.

At least one caulking group (13) that includes a plurality of caulking parts (14, 15) with different directions is formed on a plurality of thin plates (10) placed in a stacked state to fix the position of the stacked thin plates (10), and then a preset punching process is performed with respect to the thin plates (10) that have been positioned with pilot holes (12). This makes it possible to perform a high-accuracy punching process when punching the plurality of thin plates (10) placed in a stacked state, since positional deviations between the thin plates (10) are avoided and pilot pins (11) are prevented from deforming the periphery of the pilot holes (12).
