摘要:
A torque converter has an end cover or input shell which is stamped from a sheet metal plate and has a stiffening fluid portion and an outer flow formed annular rim. The impeller, turbine and stator are assembled along with a torque converter clutch after which the rim portion of the end cover is welded to the impeller. The impeller and the cover have a flange or radially extending portion that is selectively trimmed to control the dynamic balance of the assembly. The turbine member is cast with the outer core and blade portions integral and an inner core member is welded thereto. This is completed prior to assembly within the torque converter.

Disclosed are an integrally formed fan guard and its manufacturing method. The fan guard includes a top side and a circumferential side around the outer periphery of the top side, and the top and circumferential sides are formed by a metal plate by a single or multiple stamping and extrusion method. An air hole is formed by stamping at the top side or both of the top and circumferential sides for flowing air, and a central through hole is formed at the center position of the top side. In the manufacturing method, the fan guard is formed by stamping or extruding a steel plate directly by stamping and extrusion equipments. The invention does not require a high welding skill, and the fan guard so manufactured has the advantages of high efficiency, consistency, and pass rate, and thus reducing the production cost significantly.

A method of manufacturing an integral reverse buckling fluid pressure rupturable apparatus comprised of a support body formed of a ductile material having opposite ends and having a recess extending inwardly from one of the opposite ends, the internal terminus of the recess being positioned in close proximity to the other of the opposite ends of the body or to the terminus of another recess extending inwardly from the other of the opposite ends, whereby a relatively thin integral concave-convex rupturable portion is formed in the body having a known reverse buckling rupture pressure.

A METHOD OF FORMING A REINFORCED SHEET METAL CORNER JOINT WHEREIN A FLANGE IS FORMED ACROSS A WELDED JOINT IN SUCH A WAY AS TO GATHER THE METAL TOWARD THE JOINT AND EFFECTIVELY PRECLUDE SPLITTING OF THE JOINT IN THE FORMATION OF THE REINFORCING FLANGE. THE METAL IS GATHERED TOWARD THE WELDED JOINT BY MEANS OF A V-SHAPED CONCAVE DIE WHEREBY THE EDGE OF THE METAL SHEETS IS PROGRESSIVELY TURNED AS THE DIE SURFACES MOVE ALONG THE METAL EDGE PROGRESSIVELY TOWARD THE APEX OF THE DIE. THE SHEET METAL IS FIRMLY HELD ADJACENT THE EDGE BY SUITABLE CLAMP MEANS PERMITTING THE EDGE TO BE TURNED BY THE DIE INTO ACURATE PERPENDICULAR RELATIONSHIP TO THE CORNER JOINT.

There is provided a method of producing acoustic damping elements having an acoustic resistance. For that purpose at least one sleeve with a hole having a diameter is placed below a base material. At least one hole is stamped in the base material by at least one punch having a punch diameter. The punching operation is repeated at various positions on the base material.

Disclosed is a multi-layered composite panel. The multi-layered composite panel comprises at least two sheets of thin plates with continuous waveform patterns having the same pitch and different heights in one direction are overlapped. In the multi-layered composite panel, an air layer is formed between the overlapping thin plates, orthogonal pressing portions, which divide the waveform patterns on the top and the bottom of the thin plates into the unit of triangle-patterned cell by being pressed orthogonally to cross each other on the top and the bottom of the thin plates overlapping in the orthogonal direction crossing the direction of the waveform patterns, are formed and an undercut portion is formed by pressing the centers of both sides connecting a groove and a ridge of each cell on the top and the bottom of the thin plates with opposite orthogonal pressing portions.

A method for manufacturing a vented board includes the steps of providing a metal plate, forming a mesh area in the plate, and punching a recessed portion on the plate to make at least one part of the mesh area extend to form a side wall of the recessed portion with a thickness of the mesh area substantially remaining constant. The mesh area includes a number of hole units. Each hole unit defines a hole and includes a plurality of borders bounding the hole. Every two adjacent hole units share a corresponding one of the plurality of borders. Before punching the recessed portion, a center line of each border is a curve line.
