4results about How to "Solve molding difficulties" patented technology

The application discloses a composite landing gear for a vertical take-off and landing aircraft and a forming method thereof; the method comprises the following steps: S1, according to the structural shape of the landing gear, a hollow-structure metal frame 1 is made through 3D printing profiling; the surface of the metal frame is cleaned and is ready for use; S2, the two end openings of the metal frame are sealed, and a composite material prepreg is laid on the surface of the metal frame; meanwhile, cold extraction pre-compaction and hot pre-compaction are carried out during the laying process of the composite material prepreg; S3, after the laying of the composite material prepreg is completed, vacuum extraction is carried out for compaction, and then the metal frame is put into a hot pressing tank for solidification; S4, after the solidification, the material used for compaction is removed, the sealing material at the two ends of the metal frame is removed, and a plurality of connecting holes used for being connected with the aircraft body are processed at one end, so that the composite material landing gear is obtained. The forming method provided by the application adopts integral forming of the internal metal frame and the composite material part with an external special-shaped structure, so that the risk of assembly is reduced, and the assembly difficulty is reduced.

A side wall tail lamp mounting structure, comprising a side wall outer plate (1) and a tail lamp mounting plate assembly (2), the side wall outer plate (1) and the tail lamp mounting plate assembly (2) are welded, the tail lamp mounting plate assembly (2) comprises a tail lamp mounting connecting plate (21), an upper tail lamp mounting plate (22) and a lower tail lamp mounting plate (23), the lower tail lamp mounting plate (23) comprises a first welding edge (231) and a second welding edge (232), the first welding edge (231) and the second welding edge (232) are adjacent, the tail lamp mounting connecting plate (21) and the first welding edge (231) are welded, the upper tail lamp mounting plate (22) and the second welding edge (232) are welded, and the tail lamp mounting connecting plate (21) and the upper tail lamp mounting plate (22) are respectively welded on the side wall outer plate (1). A side wall tail lamp mounting method, an automobile tail lamp and an automobile are also disclosed. By splitting the traditional tail lamp mounting plate into smaller parts, the precision of the parts is improved; the problem that the tail lamp mounting plate is difficult to form and prone to cracking in the stamping direction due to the maximization of the tail lamp light-emitting area in the prior art is solved.

The application discloses a manufacturing method of bamboo shoot fiber nutrition rice, and belongs to the technical field of food processing. The manufacturing method of the bamboo shoot fiber nutrition rice is as follows: bamboo shoot raw materials are sliced, airflow dried, coarsely pulverized and ultra-micro pulverized to prepare fiber fine powder with a particle size of 1-10 microns; the fiber fine powder is mixed with glutinous rice powder or cassava starch, whey protein powder and the like according to a mass ratio of 7.15-88.97:7.85-85.86:0-36.53 to prepare pulp; 0.3g of glutamine transaminase is added for treatment; three-stage heating and extrusion molding are carried out; and after drying and polishing, the nutrition rice is prepared. The application improves the taste of the bamboo shoot raw materials through ultra-micro pulverization, solves the molding problem through enzyme treatment and segmented heating and extrusion, and prepares the nutrition rice with a dietary fiber content of 5-50.5% and a protein content of 5-30.7%, fills the market blank of high-dietary-fiber nutrition rice, and can fully utilize bamboo shoot resources, and has economic and social benefits.

This utility model belongs to the field of battery pack structure technology and discloses a battery pack cover structure, including an upper plate and a lower plate spaced apart, and a set of vertical ribs disposed between the upper plate and the lower plate. The set of vertical ribs includes multiple supporting vertical ribs spaced apart in a first direction, and each supporting vertical rib extends along a second direction and connects to the upper plate and the lower plate. The double-layer structure of the upper and lower plates ensures the overall rigidity of the cover structure, while solving the problem of complex design and stamping difficulties caused by similar box covers. It can ensure the rigidity of the cover structure without increasing its weight.
