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;

Abstract

The invention discloses a semi-honeycomb steel belt hobbing machine for ensuring a uniform forced convection flow field. The machine comprises a feeder and a discharger, and further comprises two toothed trapezoidal gears having the same number of teeth, wherein the trapezoidal gears are mounted on a driving shaft and a driven shaft respectively; the driving shaft is connected with a spindle of a reducer motor via a coupler; the two trapezoidal gears are mounted in an engaged manner; and a clearance between tooth faces of the trapezoidal gears is the thickness of a steel belt. With the adoption of the technical scheme, the steel belt is extruded into a semi-hexagonal semi-honeycomb steel belt when the steel belt participates in an engagement process by using a gear engagement principle; the dimensional uniformity of the sides of a semi-hexagon is good; tensile deformation of the steel belt is small; production efficiency is high; a fine adjustment mechanism of a driven gear shaft is designed; the problems of excessive extrusion and tension of the steel belt due to fine change in the thickness of a steel sheet are solved by finely adjusting a distance between a driving gear and a driven gear; the problem of great arc distortion of the semi-honeycomb steel belt is solved by finely adjusting the parallelism of the driving gear and the driven gear; and the machine is simple in structure and convenient to use and adjust.

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] like 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 st...
