Abstract: A bending assembly for extruded, stock material specifically including elongated channel stock initially supported on a mandrel in an operative position relative to a forming assembly which includes a movable section and a fixed section. The movable section includes a forming channel disposed about a periphery thereof and having a predetermined curved configuration corresponding to the intended curve of the stock material to be bent. Cooperative placement and structuring of the movable and fixed sections continuously force the stock material into the forming channel and along the length thereof upon travel of the movable section through a forming cycle. A locking assembly is structured to secure the stock material to the movable section, such that the stock material moves relative to the both the movable and fixed sections and with the movable section during the forming cycle. A brace assembly is mounted interiorly of the stock material in order to prevent unwanted deformation thereof.

Abstract: A contact magazine loader for guiding the insertion of individual electrical contacts into a crimping section of a crimping tool. A magazine is adapted to be placed in removable and rotatable engagement with a hand-held crimping tool. The magazine is approximately cylindrical, has a plurality of channels evenly dispersed around the radial periphery of the magazine, and is preloadable with electrical contacts. Each preloaded electrical contact is positioned within an individual insert casing. Each insert casing is adapted to being linearly slideably received into one of the channels. As a shuttle assembly is moved into compressed configuration, an insert casing guides the preloaded electrical contact into the crimping section of the hand-held crimper. A trigger assembly allows a user, with a single movement, to cause the shuttle assembly to return to its released configuration, and to rotate the magazine to axially align a subsequent casing with the crimping section of the hand held crimper.

Abstract: A steel pipe drawing apparatus, which can manufacture a drawn steel pipe which is a long object with high accuracy and at high speed as well as improves dimensional accuracy of respective thick-wall portions and cutting positions of the drawn steel pipe, is realized. When a stepped drawn steel pipe is manufactured by moving a die and a plug relatively in the same direction as a steel pipe drawing direction and in an opposite direction thereto, a first hydraulic cylinder moves the die relatively in a direction corresponding to the steel pipe drawing direction, and a second hydraulic cylinder moves the plug relatively in a direction opposite to a moving direction of the die. At this time, a position detecting sensor detects a stroke position of the second hydraulic cylinder, and a computer receives positional information detected by the position detecting sensor and controls a moving velocity of the second hydraulic cylinder.

Abstract: Apparatus and method of controlling strip geometry in casting strip having a rolling mill. A target thickness profile is calculated as a function of the measured entry thickness profile of the strip while satisfying profile and flatness parameters. A differential strain feedback from longitudinal strain in the strip is calculated by a control system by comparing the exit thickness profile with the target thickness profile, and a control signal is generated to control a device capable of affecting the geometry of the strip processed by the hot rolling mill. A feed-forward control reference and/or sensitivity vector may also be calculated as a function of the target thickness profile, and used in generating the control signal sent to the control device. The control device may be selected from one or more of the group consisting of a bending controller, gap controller and coolant controller.

Abstract: A method corrects a head suspension by irradiating an objective part of the head suspension with a laser beam. The method is capable of precisely correcting the head suspension even when correcting the head suspension a plurality of times. The method removes residual stress created by the preceding correction from the head suspension, and then, carries out the next correction. Accordingly, the method can precisely correct the objective part of the head suspension with a laser beam even if the objective part has once been irradiated with a laser beam in the preceding correction.

The die assembly according to the present invention comprises a die core (3); at least one pre-stressed ring (2) placed around the die core (3); and a die casing (1) surrounding the ring (2), wherein the ring (2) is plastically deformed and hardened by press fitting it to the casing (1) so that the ring has compression stress exceeding its material yield limit by 10-40%, and the mating geometric feature (5) of the core and the ring is tapered towards the exit, to thereby obtain a rigid container system in which a die core can be press fitted with a great force without die cracking. As a result, a long lasting die assembly with surprisingly high performance, small dimension and low production cost is obtained by assembling the die core by a great force without die cracking.

Abstract: This invention is a manually operated tube bending machine with a power drive mechanism that is adjustably set to a desired bend speed. The bending machine includes a bending die, a counter die and a rotating hook die to form a desired bend into a tube or pipe. The tube bender includes a drive wheel with ratchet teeth around its perimeter. A drive pin grips one of the ratchet teeth. The drive pin is secured to a lever and torque bar. During each bending stroke, the lever and torque bar incrementally rotate the drive wheel a desired amount. The rotation of the drive wheel and hook die draw the tube through the bending and counter dies to bend the tube. An anti-spring back mechanism holds the position of the drive wheel while the power drive mechanism is advanced to grip the next ratchet tooth of the drive wheel.
