This invention relates to the field of door and window technology, and discloses an aluminum-clad wood door and window corner process, including an aluminum corner structure, a wood frame assembly, and a snap-fit ​​connection mechanism. The process includes the following steps: aligning the boss at the end of the wood frame with the guide groove of the aluminum corner, and inserting the boss into the guide groove at a 45° angle; rotating the wood frame to a vertical position until it is engaged and locked by the snap-fit ​​connection mechanism, and confirming that the wood frame is not loose after locking; applying weather-resistant sealant between the wood frame strip and the wood frame, and using self-tapping screws with anti-loosening structure to fix the wood frame strip and the wood frame together, completing the assembly. By using a standard aluminum corner and snap-fit ​​connection, the automatic engagement characteristic of the snap-fit ​​connection simplifies the on-site assembly process. The improved structure reduces the processing precision requirements of the wood components, reduces the scrap rate caused by dimensional deviations, and improves the utilization rate of raw materials, solving the shortcomings of low on-site assembly efficiency, high dependence on personnel skills, and serious waste of raw materials.

This invention relates to a wide-width high-temperature carbonization furnace, belonging to the technical field of carbon fiber production equipment. The furnace chamber of this invention has an arched top plate, and the connection between the arched top plate and the side plates is a sliding groove engagement. The furnace body contains an ash accumulation chamber, a graphite scraper capable of completely covering the ash accumulation chamber, and a graphite scraper driving mechanism. The ash accumulation chamber is connected to injection and suction ports located on both sides of the furnace body. The arched top plate of this invention, which is slidably supported by the side plates, provides strong structural stability. Furthermore, the movable graphite scraper and ash accumulation chamber within the furnace allow for automatic cleaning of the furnace without shutting down the production line.

This invention provides a cam, a harmonic reducer, and a robot. The cam includes a cam body with a groove extending radially to the outer edge of the cam body and penetrating the cam body along its thickness. According to this invention, by constructing a groove extending radially to the outer edge of the cam body and penetrating the cam body along its thickness, this design not only reduces the cam's own weight and decreases the contact area between the cam and the flexible bearing, resulting in better structural mechanical properties, but also provides a buffer space for elastic deformation and vibration absorption during the operation of the harmonic reducer. This facilitates high-speed, low-noise, and low-vibration operation of the harmonic reducer, thus meeting the design requirements of the robot.
