A method for texturizing a workpiece uses a die assembly installed within a press having a press ram. The method includes (a) delivering the workpiece onto a center die plate; (b) forcing the press ram against an upper die plate mounted above the center die plate to descend a first contact surface associated with the upper die plate and a plurality of blades mounted to the upper die plate toward the center die plate; (c) actuating horizontal movement of the blades; (d) driving the blades down into the workpiece; and (e) contacting the first contact surface to a second contact surface associated with the center die plate to descend the center die plate in unison with the upper die plate.

A liquid cooled coldplate has a tub with an inlet port and an outlet port and a plurality of pockets recessed within a top surface of the tub. Each pocket has a peripheral opening and a ledge, the ledge disposed inwardly and downwardly from the peripheral opening. The inlet port and outlet port are in fluid communication with the pocket via an inlet slot and an outlet slot. A plurality of cooling plates are each received by a pocket and recessed within the pocket. Each cooling plate comprises an electronics side for receiving electronics and enhanced side for cooling the cooling plate. The enhanced side of the cooling plate comprises a plurality of pins formed by micro deformation technology. The tub may be formed by extrusion.

Provided are a method for splitting longitudinally an end part of a metal plate or a metal rod having a rectangular, polygonal, or elliptical shape, in which the length of incision in the split portion can be freely adjusted and smooth split face can be formed; a metal part manufactured by such method; and a method for bonding such metal part. The present invention is characterized by the process comprising the steps of securing a metal plate by pinching both sides thereof with a clamping device, or securing a metal rod by pinching at least two opposite-facing portions on the periphery thereof with a clamping device; splitting longitudinally by slitting or cleaving the metal plate, or the metal rod, by pressing a slitting punch or a cleaving punch against the face of one end of the metal plate, or the metal rod; and advancing the splitting further by repeating the same operation of pressing the same punch stated above against the cleft of the splitting; and is characterized further in that, in each time of the press-splitting operation, the position of the clamping device on at least one side is moved in advance of the next pressing by a stroke corresponding to the distance from one end of the metal plate, or the metal rod, to the distal end of a split-desired portion.

A workpiece includes a material with a face and a first plurality of barbs and a second plurality of barbs extending integrally from the face. Each barb has a height above the face. The barbs of the first plurality are at least 10% higher than the barbs of the second plurality. The first plurality of barbs includes at least 10% of the barbs on the face and the second plurality of the barbs includes at least 10% of the barbs on the face. The barbs of the second plurality of barbs are bent and pointed.

A substrate for electronic components is formed by bonding a cooling metal layer to one side of a ceramic tile and bonding an electronic metal layer to the other side of the electronic tile. The substrate is secured to a machining base and the cooling metal layer surface is enhanced through an MDT process. In the process, fins are sliced into the cooling metal layer with a tool to a depth of less than the cooling metal layer thickness. The slicing forces material upward without removing material from the cooling metal layer, forming fins that extend beyond the original thickness of the cooling metal layer. The fins can be cross-sliced at an angle to form pins.

An apparatus is provided for texturing the surface of a brake plate has three die plates and spring supports therebetween. A toothed tooling mounts to the top die plate above an anvil on the center die plate both of which ride on posts held by the lower die plate. The toothed tooling comprises multiple blades each with multiple replaceable toothed inserts are held in a cartridge arrangement. The anvil receives brake plates from a separately supported plate feed mechanism with greatly reduced reciprocating mass. The complete die set can be set up on the bench and inserted ready to use in any style of press where the press ram contacts the upper die plate.

A process is provided for making bulk textured material sheeting. As a continuous supply of flat material sheeting is fed, the sheeting is repeatedly impacted with toothed knives, each knife creating a row of raised and generally pointed structures on the sheeting to texture the sheeting.

A protrusion forming device includes a holding portion holding an object that is be processed, a tool bit having a cutting portion capable of cutting an object held by a holding portion, and a drive portion capable of driving the tool bit. The tool bit is movable along a cut-in pathway so that the cutting portion is inserted into the object. The cutting portion is movable along a further-cut pathway so as to form a protrusion part that is cut in a linear shape and is connected to the object. The tool bit continuously contacts the protrusion part while moving along a forming pathway such that the protrusion part extends perpendicular to an outer surface of the object.

The invention relates to a method (100) for manufacturing a fastening arrangement for fastening a collar to a tube. The method comprises the steps of providing a hollow tube (10), arranging said tube for receiving at least one forming punch (30) in the axial direction of the tube, punching the tube with a forming punch at an inner radial part of an edge portion (16) of the tube in the axial direction of the tube, locally reducing the tube thickness, so that the material being punched is plastically relocated in the axial direction, locally forming a snap portion (11) in the form of a flange (12) in the radial direction towards the hollow inside of the tube, providing a collar (20) configured to be arranged on the tube, wherein the collar comprises at least one receiving portion (21) arranged to receive said snap portion, and arranging the collar to the tube such that the snap portion engages with said receiving portion.
