This invention provides a double-sided asymmetrical rotor profile for a high-pressure twin-screw compressor, comprising a male screw rotor and a female screw rotor. The profiles of the male and female rotor teeth mesh with each other and have the same outer diameter. The tooth profiles of the female rotor teeth sequentially include: female I circular arc, female II circular arc, female III circular arc, female I elliptical arc, female circular arc envelope, female IV circular arc, female II elliptical arc, female straight line, and female V circular arc. The tooth profiles of the male rotor teeth sequentially include: male I circular arc, male I circular arc envelope, male II circular arc envelope, male I elliptical arc envelope, male II circular arc, male III circular arc, male II elliptical arc envelope, male straight line envelope, and male III circular arc envelope. This invention's tooth profile is easy to grind, achieving higher surface accuracy. It features a short contact line, wide sealing surface, small leakage triangle, and small pressure difference between working chambers, improving sealing performance, reducing noise and vibration of the main unit, and increasing the lifespan and long-term operational reliability of the main unit bearings.

This utility model relates to a hot stamping grid assembly inspection fixture, comprising a base, a plurality of first mounting seats vertically fixedly connected to the top of the base, a top plate horizontally fixedly connected to the top of the first mounting seats, a plurality of flip seats fixedly connected to the top of the top plate, a cover plate rotatably connected to the top of the flip seats, a mounting plate fixedly connected to the bottom of the other end of the cover plate, a plurality of first contour plates fixedly connected to the bottom of the mounting plate, and a pair of second mounting seats provided on both sides of the top plate, with second contour plates fixedly connected to the side walls of the second mounting seats. The beneficial effects of this utility model are that, by providing first, second, and third contour plates, the workpiece can be conveniently installed according to its contour, significantly improving installation accuracy. Simultaneously, it facilitates the inspection of the surface accuracy and edge contour of the workpiece, improving inspection efficiency.

The embodiment of the application provides a glass fiber honeycomb material processing method, and relates to the technical field of honeycomb composite material processing.The method is characterized in that: rough machining and semi-finishing machining are performed on the thin wall of a part to reserve a uniform machining allowance; the allowance after the semi-finishing machining is divided into a plurality of independent blocks separated from each other through block cutting; and the allowance after the block cutting is finished to a target size.Through the pre-separation of the allowance into independent blocks separated from each other, the stress transmission path between the allowance material and the reserved thin wall is cut off, the cutting force generated in the finishing is limited within a single block and cannot be continuously conducted to the node along the honeycomb wall, thereby preventing the node from being debonded and the thin wall from being missing, and ensuring the forming integrity and profile accuracy of the knife-edge thin wall.

This utility model discloses a stator blade machining milling cutter with convenient heat dissipation, relating to the field of milling cutter technology. It includes a tool holder with a machining head fixed to its bottom end. The machining head has a cooling assembly inside, comprising an annular sleeve rotatably connected to the curved outer wall of the tool holder, with a connecting pipe on one side of the annular sleeve. This utility model utilizes coolant flowing in an annular groove to cool the machining head, extending its service life. Simultaneously, the coolant is sprayed out from a cooling groove at the rear end of the tool holder, further improving the cooling effect and reducing heat transfer between the tool holder and the machining head. This rapidly removes cutting heat, preventing dimensional deviations caused by softening or thermal deformation of the blade material due to high temperatures, thus improving the blade's profile accuracy. Furthermore, the coolant sprayed from the cooling groove can directionally flush away chips, preventing long chips from entangled in the machining head and reducing scratches on the blade surface during machining.
