Plastic working method for magnesium alloy

A plastic working method for a magnesium alloy, wherein the magnesium alloy is subjected to a friction stir process whereby a probe at the tip portion of a tool rotating around an axial line is press-fitted to the surface of the magnesium alloy, the magnesium alloy is heated and softened by friction between the magnesium alloy and the rotating tool, and the tool is moved parallel to the surface of the magnesium alloy while the tool is rotated with the probe in the press-fitted state. When the length in a first direction of the region of the magnesium alloy being plastically worked is A, and the amount of shrinkage of the magnesium alloy in the first direction due to the friction stir process is , A+ is set as the length in the first direction of the region subjected to the friction stir process.

Devices and methods for bending or cutting implants

Devices and methods for bending or cutting implants are disclosed herein. In some embodiments, an instrument can include a rotatable drive shaft that urges first and second portions of a modular bending or cutting template toward one another to bend or cut an implant disposed between the template portions. A linkage assembly can be included to provide a mechanical advantage in urging the template portions toward one another. In some embodiments, an instrument can include a rotatable drive shaft that, depending on direction of rotation, pushes or pulls a first modular template portion with respect to a second modular template portion to bend an implant disposed between the template portions in one direction or another direction. In some embodiments, an instrument can include a worm drive that rotates a cutting wheel with respect to a cutting plate to cut an implant inserted through openings formed in the cutting wheel and the cutting plate.

Method and device for producing a metallic strip in a continuous casting and rolling process
10434552 · 2019-10-08 · ·

A method for producing a metallic strip by continuous casting-rolling, wherein a slab is cast in a casting machine and then sent to a finishing mill located downstream, relative to the transport direction of the strip. In the event that the transport of the slab or strip comes to a complete or substantially complete standstill, the following steps are carried out: (a) cutting through the strip at a first point; (b) cutting through the strip at a second point that is 0.1-5.0 m upstream from the first point; (c) removing the cut-out piece of strip to create a gap in the strip; (d) conveying new strip material into the area of the gap from the area located upstream of the first point; and (e) cutting off pieces of the new strip material conveyed from upstream according to step (d) and removing the pieces from the transport line.

Backplate, support frame for backlight unit, backlight unit and display device

The present invention relates to the display technology field, and provides a backplate, a plastic-iron integrated structure, a backlight unit, and a display device. The backplate is provided with a first through hole, and the first through hole has an inner wall and an outer wall which form a projection structure on the backplate. When the backplate is bonded with a plastic frame to form the plastic-iron integrated structure, the plastic frame not only contacts the inner wall of the first through hole, but also contacts the surface of the projection structure, thus increasing the contact area between the plastic frame and the backplate, and increasing the bonding force between the plastic frame and the backplate. Even when the plastic frame shrinks in case of fluctuations in temperature and/or humidity, the plastic frame is not easily separated from the backplate, and the stability of the formed plastic-iron integrated structure is improved.
