摘要： A method can be used for inserting a hairpin in a stator core. The method includes unwinding a coil spiral-wound on an uncoiler, forming a decoated portion by decoating a predetermined portion on the coil, bending the coil in multiple stages to two-dimensionally form a leg portion and a head portion of a hairpin, cutting the coil formed with the leg portion and the head portion by a predetermined length, and moving the hairpin to be inserted into a stator core while three-dimensionally forming the head portion.

摘要： A handheld tube bender with bending disc die that includes a die level and a rotating handle level that allows the user to make accurate, level bends in many planes. The die level and angle markings can be viewed from either the front or the back side of the tube bender to allow operation when the site of the tube to be bent and the angle required for the bend only allows the user to view the back side of the tube bender. The handheld tube bender may be limited to being able to bend a specific diameter of tube or may be adjustable to bend tube of many different diameters.

摘要： A conduit coupling includes a first connector at a first end of the conduit coupling, a second connector at a second end of the conduit coupling, and a stem between the first connector and the second connector. A first end of the stem is attached to the first connector. A second end of the stem is attached to the second connector. The stem is bent at a particular bend angle along a bend plane. The first connector includes an indicator that indicates an orientation of the bend plane.

摘要： Systems providing robotic bending used to bend a surgical rod are disclosed. Such systems may include a processor and memory coupled with the processor. The memory includes computer readable program code so that when the computer readable program code is executed by the processor, the processor performs operations including providing a set of transformation points corresponding to respective attachment implants, generating a bend plan for the surgical rod based on the set of transformation points, and generating an image output to render the set of transformation points and the bend plan on a display. Related methods and computer program products are also discussed.

摘要： A skate blade bending apparatus (35) may feature a unitary body (1) with a securement structure (10, 15) which holds a skate blade on its side, parallel to the ground, and a means for exerting downward force (8) on the side of the skate blade. The securement structure may feature movable anvils 15 which will change the imparted radius of curvature imparted upon the blade. Indicia (29) may be utilized to position said anvils (15) to ensure the process is repeatable on different blades. A handle (14) used with the means for exerting downward force (8) may be adjustable. The means for exerting downward force (8) and anvils (15) may be interchangeable with other shapes of similar structures for greater versatility.

摘要： Provided is a method of manufacturing a pipe including a large-diameter portion, a small-diameter portion, and a reduced diameter portion connecting the large-diameter portion and the small-diameter portion, the method comprising: forming a metal plate member into a U-shaped member having a U-shaped cross section; and forming the U-shaped member into a shape of the pipe. The U-shaped member includes: a curved portion facing an opening between both edges of the U-shaped cross section; and two facing side walls continued from the curved portion. An opening degree of the two facing side walls in a portion to form the small-diameter portion is larger than an opening degree of the two facing side walls in a portion to form the large-diameter portion.

摘要： One box body is attached to an undercarriage of a trailer, and provided with a brazing area, a gastight testing area, and a finishing area aligned with one another in this order along a first side wall of the box body the brazing area, a plurality of members are bonded together by brazing to produce a half-finished product. In the gastight testing area, gas-tightness of the half-finished product is tested. In the finishing area, the half-finished product is covered with a thermal insulator to completely produce a pipe component. As a result, it becomes possible to properly dispose a working area, where the pipe component is produced, in the interior space of one box body without losing workability.

摘要： A bending wheel of a tube bending apparatus includes a tube-accepting recess, proximal and distal wheel faces, and a rotation recess. The proximal wheel face includes a lever pivot anchor. A cam insert includes a shaft having a tool driving feature. The shaft is configured for selective insertion into the rotation recess. The cam insert includes a camming flange, which includes a lever urging feature. A keeper lever includes a keeper finger rigidly connected to a laterally extending lever arm and extending longitudinally from the proximal wheel face. An anchor end of the lever arm includes an arm pivot feature and a spaced-apart cam following feature configured to interact with the lever urging feature. Rotation of the cam insert causes rotation of the lever urging feature to drive the cam following feature of the keeper lever and pivot the lever arm in the same rotational direction.

摘要： A portable, self-contained conduit bender having a housing configured to house a reductive gear set, thereby improving safety and extending the life of the conduit bender by limiting exposure of the reductive gear set to dust and debris. The conduit bender includes a motor configured to drive a driven shaft at a first rotational output, a reductive gear set operably coupling the driven shaft to an output shaft, the reductive gear set configured to reduce the first rotational output of the driven shaft to a second rotational output of the output shaft, a housing defining an interior cavity configured to house the reductive gear set, such that only a portion of the output shaft emerges from the interior cavity, and a bender shoe coupleable to the output shaft, the bender shoe defining an arcuate channel configured to receive conduit during bending operations.
