Abstract
The invention provides a resonant column fabrication method, which comprises the following steps: making a flanging pipe fitting from standard copper or brass pipe; making a hopper-like insert from a copper or brass bar; and pressing the hopper-like insert in the flanging pipe fitting in an interference manner, and fixing by silver brazing to obtain the resonant column. The method has the advantages of short production period, high material utilization rate (90%), easy processing, stable and reliable product performance, good consistency and interchangeability, and poor technical requirement for manufacturers.
Description
Technical field
The present invention relates to a kind of manufacture method of electric equipment products, particularly a kind of manufacture method of resonance post.
Background technology
The resonance post is one of key element that constitutes cavity body filter.According to the generation principle of cavity body filter resonance frequency, resonance post and closed metal cavity produce resonance frequency jointly, thereby realize the required frequency of filter.The resonance post also is resonant rod.The resonance post need have good electrical conductivity, so material adopts valuable red copper or brass surfaces silver-plated more.
The structure of resonance post as shown in Figure 1 and Figure 2, it comprises a body 1, band flange 2 in body top is provided with one and is used to insert the infundibulate connector 3 that sunk screw is fixedly linked resonance post and resonant cavity in the pipe of bottom.
The manufacture method of prior art resonance post is an integral structure component that adopts red copper bar blank to process through turning.Because axiality, flatness, roughness and the linear dimension of resonance post self are to the performance of filter influence greatly, so process equipment adopts numerically controlled lathe more and producer's technical ability is had relatively high expectations, the production cycle is long.Resonance post self its specific structure has also determined the waste of material simultaneously, and stock utilization only is 50%～60%.Material, process equipment, production cycle reach the price that the requirement of processor's technical ability has been improved the resonance post.Need in the filter to be equipped with a plurality of resonance posts, cause in a filter, the cost of resonance post is only second to cavity.
Summary of the invention
Purpose of the present invention is to overcome the problem that above-mentioned prior art exists, and a kind of manufacture method of new resonance post is provided.
The object of the present invention is achieved like this: a kind of manufacture method of resonance post may further comprise the steps:
A, be raw material, make the flange pipe fitting with standard red copper or brass tube;
B, be raw material, make the infundibulate mold insert with red copper or brass bar;
C, the interference of infundibulate mold insert is pressed in the flange pipe fitting and silver soldering is fixed, makes the resonance post.
The described flange pipe fitting inner wall of steps A is provided with the limited step that is used for setting-in infundibulate mold insert.
Handle through annular knurl on the described infundibulate mold insert of step B surface.
Compared with prior art, method of the present invention have with short production cycle, stock utilization is high (can reach 90%) and difficulty of processing is low, properties of product are stable, reliable, consistency interchangeability is good, to advantages such as manufacturing person's technical ability are less demanding.With red copper material resonances post is example, and price is 3/5 of a machining resonance post, has reduced cost significantly, has improved product profit.
Adopt method of the present invention, material is economized, operation is less, Mould Machining is easier, easily realizes mechanization and automation mechanized operation, and the efficient height can be fit to requirement of mass production.The present invention simultaneously adopts standard tube manufacture resonance post, has avoided the repeatedly punching press difficult point of drawing and forming, greatly reduces die cost.Resonance pole structure possesses good punching process character, higher, easy to operate, constant product quality of life-span.

Embodiment
The manufacture method of resonance post of the present invention is to be raw material with standard red copper or brass tube, makes the flange pipe fitting; With red copper or brass bar is raw material, makes the infundibulate mold insert; Then the interference of infundibulate mold insert is pressed in the flange pipe fitting and silver soldering is fixed, makes the resonance post.
The structure of the flange pipe fitting that the present invention makes comprises a body 1 as shown in Figure 3, Figure 4, and upper flange 2 is provided with the limited step 11 that is used for setting-in infundibulate mold insert at body 1 inwall.The copper tube or the brass tube of standard specification on the market selected in the making of flange pipe fitting for use, by diel pipe fitting is opened wide the place and expand outwardly and translate into edge-on minor face formation flange, the edge that utilizes punch die to repair cutting method orchid and pipe fitting again makes it to have certain diameter, certain altitude.The also available machining of the operation of wherein cutting edge is finished.The flange pipe fitting need carry out follow-up a small amount of machining, finish seamed edge bevelling and flange seamed edge fillet in bottom limited step, the bottom, the point discharge of resonance post burnt out filter when fillet can avoid filter to work under high-power state, the effect of limited step is the infundibulate mold insert that is pressed into spacing, and the seamed edge bevelling is for better ground connection when cooperating with resonant cavity in the bottom.
Structure such as Fig. 5, shown in Figure 6 of the infundibulate mold insert 3 that the present invention makes, the surface is provided with annular knurl 31.The making of infundibulate mold insert is a raw material with red copper or brass bar, adopts turning processing, and in surface knurling, the bottom seamed edge bevelling.The effect of surface knurling is that better interference effect, bottom edge chamfering are arranged when cooperating with the flange pipe fitting is to be convenient to welding in order to hold solder.The present invention adopts silver soldering.
