Half honeycomb steel belt hobbing machine to ensure uniform forced convection flow field

Abstract

The invention discloses a semi-honeycomb steel belt gear hobbing machine capable of ensuring uniform forced convection flow field. The driving shaft is connected with the main shaft of the reduction motor through a coupling, the two trapezoidal gears are installed in mesh with each other, and the gap between the tooth surfaces is the thickness of the steel strip. Using the above technical solution, using the principle of gear meshing, the steel strip is extruded into a semi-hexagonal semi-honeycomb steel strip during the meshing process of the steel strip. The deformation is small and the production efficiency is high; the fine-tuning mechanism of the driven gear shaft is designed, and by fine-tuning the distance between the main and driven wheels, the problem of excessive extrusion and stretching of the steel strip caused by the slight change in the thickness of the steel sheet is solved; The parallelism of the moving wheel solves the large arc distortion problem of the semi-honeycomb steel belt; the structure is simple, and the use and adjustment are convenient.

Description

technical field [0001] The invention belongs to the technical field of mechanical product processing technology, and relates to mechanical product processing equipment. More specifically, the invention relates to a semi-honeycomb steel belt hobbing machine that ensures uniform forced convection flow field. Background technique [0002] In recent years, with the demand for high-speed wind tunnel construction at home and abroad, more and more ventilation windows with small wind resistance, uniform flow field, and composed of metal honeycomb structure have been applied. This kind of honeycomb ventilation window is called honeycomb window. [0003] Such as Figure 8 , Figure 9 and Figure 10 As shown, the honeycomb window is made up of an outer frame 18 and a honeycomb panel 19 . [0004] According to needs, these windows are composed of hexagonal honeycomb grids of different sizes, and the grid material is about 0.1mm thick and 13mm wide soft magnetic steel strip or special...

AI Technical Summary

Problems solved by technology

[0016] 2. The extruded semi-honeycomb steel belt cannot have large arc distortion; otherwise, there will be local unevenness during the forming stage of the honeycomb panel, which will also affect the product performance;

[0017] 3. Try not to cause the steel strip to stretch during the extrusion forming process; otherwise, it may not only affect the straightness of the side of the semi-honeycomb steel strip, but also deform the hexagonal holes due to the gradual release of internal stress, which will eventually affect the product quality

Its disadvantages are: 1. If the 1.3m-long semi-honeycomb steel strip is extruded at the maximum, the overall size of the equipment will be large; in order to increase the rigidity, the size and weight of the equipment parts will also be large; 2. The production efficiency is low

The third disadvantage is that the steel strip is greatly stretched during the extrusion process, which does not meet the requirements

Its disadvantages are: 1. If the parallelism of the upper and lower gear shafts is not well adjusted, the large arc distortion of the semi-honeycomb steel belt will appear; 2. When extruding a parallel toothed belt with a circular gear, the tooth shape must be slightly changed The inner and outer angles of , that is, the inner angle is slightly increased, and the outer angle is slightly reduced, so as to form a circle
