Abstract
The present invention relates to a kind of methods of rapid processing corner cut waveguide, realize the rapid processing to corner cut waveguide.The method of the present invention only needs 1 waveguide, it is come out according to corner cut size design bending route and with linear cutting equipment by bending dimensioned, the processing that seam welds are completed to corner cut waveguide after simple bending, significantly improves processing efficiency and reduces production cost.
Description
Technical field
The invention belongs to mechanical manufacturing fields, and in particular to a kind of high-efficiency machining method of rectangle corner cut waveguide.
Background technology
Waveguide is widely used in field of radar, it is a kind of thin-wall rectangular profile material tube, is manufactured according to requirements
At different waveguide device.Corner cut waveguide is a kind of component of radar electromagnetic wave transmission route, and major function is to change as needed
Transmission path realizes that electromagnetic wave transmits between each subsystem of radar under the premise of ensureing to transmit signal.
The raw material for processing corner cut waveguide are a kind of standard sections, the soft aluminum rectangular tube of generally elongated thin-walled.Row
Corner cut waveguide is generally formed using two waveguides and cover board welding in the industry, needs to process 3 kinds of parts.2 waveguide end faces are first
Splice after 45 ° of milling and weld together, then milling corner cut, last welded cover plate, whole process process is long and needs 2 welderings
It connects, be easy to cause deformation, influence product quality.And positioning tool is also needed to when 2 waveguide splicings, it just can guarantee position in this way
Set relationship.
Invention content
Technical problems to be solved
For the problem that current corner cut waveguide manufacturing procedure is long, efficiency is low, the present invention proposes a kind of rapid processing corner cut
The method of waveguide realizes the rapid processing to corner cut waveguide.The method of the present invention only needs 1 waveguide, according to corner cut size design
Bending route is simultaneously come out bending dimensioned with linear cutting equipment, and seam welds are completed corner cut after simple bending
The processing of waveguide significantly improves processing efficiency and reduces production cost.
Technical solution
A kind of method of rapid processing corner cut waveguide, it is characterised in that steps are as follows：
Step 1：The method that portion uses wire cutting in the waveguide is cut into two isosceles trapezoids up and down, two isosceles ladders
Shape shares short side, and the base angle of upper isosceles trapezoid and lower isosceles trapezoid is 45 °, and the waist of upper isosceles trapezoid is longUnder
The waist of isosceles trapezoid is longThe bottom edge A=2N of lower isosceles trapezoid；The bottom edge of lower isosceles trapezoid is most from waveguide
The width of bottom end is wall thickness；Wherein, d be waveguide inner wall vertical inflection point to the vertical range of waveguide inner wall trimming, t is wave guide wall
Thickness, b are the inside wall height of waveguide；
Step 2：Waveguide after cutting is converted into from intermediate cut place, wherein two waists of upper isosceles trapezoid overlap, under
Two waists of isosceles trapezoid draw a straight line and the bottom plate of lower isosceles trapezoid overlaps；
Step 3：Bending postwave conduit is corrected shape, ensures seam alignment；
Step 4：Welding institute seam.
Advantageous effect
A kind of method of rapid processing corner cut waveguide proposed by the present invention, compared with previous processing method, advantage
It is mainly reflected in following two aspects：
(1) production efficiency is high.The only single corner cut waveguide of conventional method just needs to process 3 kinds of parts, then 2 welding and milling
Manufacture could be completed after processing, double corner cut waveguides or more corner cut waveguides need more part combination weldings, process longer.The present invention
Method only processes a waveguide tube components as required to all corner cut waveguides, is welded after direct bending, significantly improves life
Produce efficiency.
(2) manufacturing cost is low.The method of the present invention process is few, is only once welded just by self poisoning after wire cutting appearance and size
Processing is completed, process is simple, easy to operate, energy-saving, saves production cost.

Specific implementation mode
In conjunction with embodiment, attached drawing, the invention will be further described：
Step 1：The method that portion uses wire cutting in the waveguide is cut into two isosceles trapezoids up and down, two isosceles ladders
Shape shares short side, and the base angle of upper isosceles trapezoid and lower isosceles trapezoid is 45 °, and the waist of upper isosceles trapezoid is longUnder
The waist of isosceles trapezoid is longThe bottom edge A=2N of lower isosceles trapezoid；The bottom edge of lower isosceles trapezoid is most from waveguide
The width of bottom end is wall thickness；Wherein, d be waveguide inner wall vertical inflection point to the vertical range of waveguide inner wall trimming, t is wave guide wall
Thickness, b are the inside wall height of waveguide；
Step 2：Waveguide after cutting is converted into from intermediate cut place, wherein two waists of upper isosceles trapezoid overlap, under
Two waists of isosceles trapezoid draw a straight line and the bottom plate of lower isosceles trapezoid overlaps；In bending process, plasticity occurs for waveguide
Deformation stops bending after bending to final size；
Step 3：Bending postwave conduit is corrected shape, ensures seam alignment；
Step 4：Welding institute seam.
