A positioning mechanism and modular assembly are adopted, multiple sets of components can move synchronously to form and prefabricate the multi-arc-shaped gray plastic part, demolding is convenient, and the forming quality is high.

The application relates to the technical field of steel structure node connection, and discloses a node connection structure and a cooling tower, which is used for the intersection node of two overlapped and intersected rod pieces and comprises two oppositely arranged clamping plates which are distributed on the two sides of the two rod pieces and are provided with limiting grooves on the inner sides corresponding to the two rod pieces; and a clamping piece which is clamped on the edges of the two clamping plates at two ends and is fastened and connected between the two clamping plates and the clamping piece to clamp and fix the two rod pieces between the two clamping plates. In the application, the rod pieces do not need to be broken at the node, the rod pieces are provided in length, the rod pieces are obliquely overlapped, the overall stability of the structure is stronger, the strength is higher, and the limiting grooves corresponding to the two rod pieces are arranged in the two clamping plates, the two rod pieces can be constrained and limited in the preset intersecting direction, the rod pieces can be prevented from sliding, and the stability of the overall structure is further improved.

The application discloses a high-temperature heating structure and a preparation method and application thereof, and belongs to the electric heating field. The application first prepares an insulating blank, forms a heating core by combining an electrically-conductive film with an electrode, presses the heating core between two layers of the insulating blank to form a prefabricated part, connects a wire after glue removal, high-temperature treatment and fine size processing, and finally obtains the high-temperature heating structure. The application has the advantages of no high molecule, double-side insulation, safety and high-temperature resistance, integrative structure, high strength and thermal stress resistance due to the high-temperature resistant fiber, large heating area, uniform heating, simple process and easy scale production, and has wide application in the precise thermal tooling equipment field in the semiconductor and electronic manufacturing field.

The present application relates to whip antenna technical field, specifically to carbon fiber whip antenna structure and forming method. The existing carbon fiber whip antenna conduction performance is poor, the resistance value is large, the radiation efficiency is low. The carbon fiber whip antenna structure includes first metal joint, carbon fiber tube and second metal joint and the conductive wire connecting two metal joints. Its forming method is that the first metal joint and the second metal joint are installed at both ends of the mold; carbon fiber prepreg is laid; the conductive wire is wound; carbon fiber prepreg is laid again; the antenna outer surface is wrapped with metal mesh; the metal mesh is wound and fixed with the conductive wire; the connecting part of the metal mesh and the first metal joint and the second metal joint is wound with carbon fiber prepreg respectively; compaction and solidification; demolding. The carbon fiber whip antenna has good conduction performance, small resistance value, high resistance radiation efficiency, light structure quality, excellent mechanical properties, fatigue resistance, corrosion resistance, large power bearing, high radiation efficiency, long service life, high efficiency of the workpiece.

The utility model relates to a rolling battery shell edge beam, which is formed by rolling and forming a steel belt, the section of the rolling battery shell edge beam is an integrated section shaped like a Chinese character'mu ', the rolling battery shell edge beam comprises a first closed cavity, a second closed cavity and a third closed cavity which are arranged in sequence, and the first closed cavity and the second closed cavity are separated by a first reinforcing vertical rib; the second closed cavity and the third closed cavity are separated through a second reinforcing vertical rib, the first closed cavity and the third closed cavity share one upper end face, and the first closed cavity and the second closed cavity share one first lower end face. The section structure of the edge beam is formed by the steel belt through roll bending, the forming mode is simple, the number of working procedures is small, the technology is simple, the section shaped like the Chinese character'mu 'can be achieved without the working procedures such as section tailor welding and repair welding, the structure is novel, strength is high, and practicability is high.
